2013-03-08
18:16		If SQLITE_OMIT_UTF16 is defined, avoid setting the 'enc' field of Schema objects to any value except SQLITE_UTF8. Otherwise, assert() statements may fail or spurious SQLITE_NOMEM errors may be returned at the vdbe level later on. (check-in: f2fecfb2 user: dan tags: trunk)
07:10		If SQLITE_OMIT_UTF16 is defined, avoid setting the 'enc' field of Schema objects to any value except SQLITE_UTF8. Otherwise, assert() statements may fail or spurious SQLITE_NOMEM errors may be returned at the vdbe level later on. (Closed-Leaf check-in: 69746ef7 user: dan tags: experimental)

16:40		If a rollback mode transaction reduces the size of the database file, avoid actually truncating the file until after the transaction has been committed (but before the db has been unlocked). This means pages that are removed from the database by truncating the file need not be journalled. (check-in: b73847f1 user: dan tags: incr-vacuum-opt)
2013-02-22
20:57		Fix a problem with the previous commit. (check-in: 720a3cea user: dan tags: incr-vacuum-opt)

01:00		Allow an index to be used for sorting even if prior terms of the index are constrained by IN operators. (check-in: 2cef8b68 user: drh tags: trunk)
2013-02-12
22:20		Improve memory allocation error handling on WinCE. (check-in: cdbca259 user: drh tags: trunk)
22:09		A bug report coming from from Firefox (https://bugzilla.mozilla.org/show_bug.cgi?id=840377) describes an infinite recursion. We are unable to reproduce the problem. Nevertheless, this check-in should prevent the problem from ever occurring again. (check-in: b7222a2b user: drh tags: trunk)
09:46		Improve memory allocation error handling on WinCE. (Closed-Leaf check-in: 09dfc0c9 user: mistachkin tags: wince)
2013-02-11
13:47		Add extended error codes for all SQLITE_CONSTRAINT errors. (check-in: 939d8282 user: drh tags: trunk)
2013-02-09
15:37		Rename SQLITE_CONSTRAINT_RAISE to SQLITE_CONSTRAINT_TRIGGER. Put the extended constraint error codes in alphabetical order. Add many test cases for the extended constraint error codes. (Closed-Leaf check-in: 3f674375 user: drh tags: constraint-error-codes)
13:58		Add extended error codes for constraint errors. (check-in: 54611046 user: drh tags: constraint-error-codes)
2013-02-08
23:18		Fix a potential NULL-pointer dereference following an OOM error in the query planner logic for virtual tables with OR-connected terms. (Closed-Leaf check-in: 71b6c260 user: drh tags: IN-with-ORDERBY)
20:39		Make sure the virtual tables that take advantage of IN operators sort the RHS of the IN operator in the correct order according to the ORDER BY clause. (check-in: b016b754 user: drh tags: IN-with-ORDERBY)
18:48		Loop through the elements on the RHS of an IN operator in reverse order when the ORDER BY clauses specifies DESC. (check-in: f78395c8 user: drh tags: IN-with-ORDERBY)
16:04		Allow the "a=?1 OR a=?2" to "a IN (?1,?2)" transformation to work on virtual tables again. This was formerly restricted because virtual tables could not optimize IN terms. (See check-in [fad88e71cf195e].) But IN terms are now used by virtual tables (as of check-in [3d65c70343]) so the restriction can now be removed. (check-in: a917c1f0 user: drh tags: IN-with-ORDERBY)
2013-02-07
21:15		Allow an index to be used for sorting even if prior terms of the index are constrained by IN operators. (check-in: 98bf668a user: drh tags: IN-with-ORDERBY)
09:33		Fix harmless compiler warnings. (check-in: 4a7b4ee0 user: drh tags: trunk)
05:12		Add the ability to skip defining the localtime() function when being compiled for WinCE. (check-in: e1640876 user: mistachkin tags: trunk)
2013-01-30
01:46		Remove some debugging logic accidently left in the limit.test module. (check-in: 7d346250 user: drh tags: trunk)
2013-01-29
23:55		Fix LIMIT and OFFSET so that they work and do not leak memory even on complex queries involving deeply nested views of UNION ALL compounds. Ticket [db4d96798da8]. Secondary to ticket [d58ccbb3f1b7]. (check-in: 497ee36c user: drh tags: trunk)
19:14		New debugging pragmas: PRAGMA vdbe_debug=ON is short-hand for the sql_trace, vdbe_listing, and vdbe_trace pragmas. PRAGMA vdbe_debug enables tracing of sqlite3VdbeAddOp() calls. None of this is active unless compiled with SQLITE_DEBUG. (check-in: ae565ff3 user: drh tags: trunk)
2013-01-28
22:52		Fix an issue with the SQLITE_TESTCTRL_EXPLAIN_STMT and compound queries with multiple terms. (check-in: a6499c25 user: drh tags: trunk)
19:00		Issue an error message and quit (rather than overflowing a reference counter) if the number of references to a table exceeds the maximum due to nested UNION views. Fix for ticket [d58ccbb3f1]. (check-in: c2462a95 user: drh tags: trunk)
18:18		Cause the command-line shell to issue an error message if you give something that does not look like a boolean value to a dot-command that wants a boolean argument. (check-in: b4d94947 user: drh tags: trunk)
2013-01-26
19:31		Add a single test case to fts4unicode.test to verify that title-case maps to lower case. (check-in: 955a9459 user: drh tags: trunk)
19:26		Add a single test case to fts4unicode.test to verify that title-case maps to lower case. (Leaf check-in: 46f7c930 user: drh tags: branch-3.7.15)
2013-01-25
19:11		Fix the test_spellfix.c extension so that it can be made loadable at run-time. Add spellfix to the shell when building using the build-shell.sh script. (check-in: 7813b17d user: drh tags: trunk)
18:33		Enhance the command-line shell so that adding a non-zero numeric argument to the ".exit" command causes an immediate exit without cleaning up. This can be used (for example) to cause journal files to be left behind. (check-in: 8ba951d1 user: drh tags: trunk)
15:59		Add btree-page decoding logic to showwal.c. Commands of the form: "showwal $FILE 123bmc" show the content of the btree page in frame 123. "b" means decode the btree. "c" means show cell content. "m" means give a map of the btree page. (check-in: 93b159da user: drh tags: trunk)
15:31		Further improvements to showwal.c: Reset the checksum after each frame so that only individual checksum failures are shown. And only show failures, not correct checksums. (check-in: 4e2bf575 user: drh tags: trunk)
15:09		Enhance the "showwal" utility program to show checksum failures on frames. (check-in: a7f6d198 user: drh tags: trunk)
02:10		Enhancements to the query planner to exploit transitive relationships in the WHERE clause, and other minor changes to bring the sessions branch into alignment with the trunk. (check-in: 82d3d1ae user: drh tags: sessions)
2013-01-23
18:53		Improved parsing of the arguments to the ".backup" command in the command-line shell. (check-in: f1127e87 user: drh tags: trunk)
18:44		Fix a double-free() call that can occur when SQLITE_ENABLE_TREE_EXPLAIN is defined. (check-in: 5bfb5967 user: drh tags: trunk)
2013-01-20
00:18		Fix a typo in a comment in the test_regexp.c test file. (check-in: 68346af7 user: drh tags: trunk)
2013-01-18
03:35		The \xXX escape in the test_regexp.c must be followed by exactly two hex digits. (check-in: 82957495 user: drh tags: trunk)
2013-01-17
17:20		Enhance the query planner to exploit transitivity of join constraints. (check-in: 38852f15 user: drh tags: trunk)

16:43		Add the ability to disable transitive constraints using the sqlite3_test_control(SQLITE_TESTCTRL_OPTIMIZATIONS) interface. (Closed-Leaf check-in: 593d67c8 user: drh tags: transitive-constraints)
16:18		Avoid unnecessary collating sequence and affinity restrictions on the use of transitivity. Add test cases to show that the restrictions are not needed. (check-in: 56549f45 user: drh tags: transitive-constraints)
15:05		Make more aggressive use of transitivity in optimizing queries. Add a test case. (check-in: d9676284 user: drh tags: transitive-constraints)
03:18		Enhance RTree virtual table creation error messages that involve the getNodeSize() function. (Closed-Leaf check-in: 652233d6 user: mistachkin tags: rtreeErrMsg)
03:18		Make the 'fs' virtual table module portable to Windows. (Closed-Leaf check-in: dd473cae user: mistachkin tags: fsVfsWin)
00:08		Improved comments explaining the operation of the findTerm() utility routine in where.c. Increase the maximum number of levels of transitivity from 4 to 11. (check-in: fe152f8b user: drh tags: transitive-constraints)
2013-01-16
20:33		Fix the activate_extensions pragma so that it is a no-op when the required argument is omitted. (check-in: 6195ebd8 user: drh tags: trunk)
17:08		Enhance the query planner to exploit transitivity of join constraints in a multi-way join. (check-in: 13171eb5 user: drh tags: transitive-constraints)
00:46		Improvements to query planning for joins: Avoid unnecessary calls to "optimal scan" checks in cases where table reordering is not possible. Make sure optimal scan checks are carried out for CROSS JOINs and LEFT JOINs. (check-in: d5ebb787 user: drh tags: trunk)
2013-01-15
18:49		Fix a missing word in a comment. Enhance the "wheretrace" debugging output to show the estimated cost of each table option while planning the join order. (check-in: ac4e119a user: drh tags: trunk)
16:15		Clarification to a comment in where.c. No code changes. (check-in: 04507c17 user: drh tags: trunk)
2013-01-11
09:58		Add another test for the fts4 content= option. (check-in: 7e6007a0 user: dan tags: trunk)
2013-01-09
15:44		Check in an extra test for the fts4 "content=" option. No code changes. (check-in: 0d0e5ab8 user: dan tags: trunk)
14:49		Merge latest trunk changes into the sessions branch, especially the ORDER BY bug fix of 3.7.15.2. (check-in: 34af6fac user: drh tags: sessions)
11:53		Version 3.7.15.2 (check-in: c0e09560 user: drh tags: version-3.7.15.2, branch-3.7.15)
11:44		Fix an over-aggressive optimization of ORDER BY on a three-way join where the second table is UNIQUE and the ORDER BY occurs on the third table. Ticket [c997b11c4d53a2ee]. (check-in: 3d0609c9 user: drh tags: branch-3.7.15)
11:31		Fix an over-aggressive optimization of ORDER BY on a three-way join where the second table is UNIQUE and the ORDER BY occurs on the third table. Ticket [c997b11c4d53a2]. (check-in: 5774f217 user: drh tags: trunk)
11:27		Fix the date on the new orderby3.test test case. (check-in: 7249bfc2 user: drh tags: trunk)
11:25		Add a test case that demonstrates ticket [c997b11c4d53a2ee9983]. (check-in: 598f5f75 user: drh tags: trunk)
2013-01-08
17:24		Merge updates from trunk. (Closed-Leaf check-in: f29680c4 user: mistachkin tags: configReadOnly)
12:48		Do not raise an error if an unknown SQL function is found in a CHECK constraint while parsing the schema of an existing database. (check-in: cda79028 user: drh tags: trunk)
2013-01-07
17:31		Merge updates from trunk. (check-in: bf90f1fb user: mistachkin tags: configReadOnly)
13:26		Do not raise an error if an unknown SQL function is found in a CHECK constraint while parsing the schema of an existing database. This version causes a run-time error when processing STAT3 tables. (Closed-Leaf check-in: 0a1207c8 user: dan tags: mistake)
2013-01-05
17:17		More bug fixes to the test_regexp.c module. Bring test_regexp.c into alignment with the regexp.c file in the Fossil sources. (check-in: 7695b88f user: drh tags: trunk)
2013-01-04
22:26		Remove superfluous text from a comment. (check-in: e9ac5339 user: mistachkin tags: trunk)
20:45		Do not use umask() since it change the umask for the entire process, not just the thread using SQLite. Make whatever permission changes are needed using fchmod() after the file is created, instead. (check-in: 6c4c2b7d user: drh tags: trunk)
19:22		Fix an out-of-order local variable declaration in test_regexp.c. (check-in: 8285b15a user: drh tags: trunk)

22:22		Merge recent trunk changes into the sessions branch. (check-in: 7e068e39 user: drh tags: sessions)
19:34		Bring back test_regexp changes that were made when porting to Fossil. Also fix some bugs that were introduced by the Fossil port. (check-in: 45c158b1 user: drh tags: trunk)
18:07		Improvements to column name resolution in queries with parenthesized FROM clauses. Also includes a fix for ticket [beba9cae6345a3]. (check-in: 99127a66 user: drh tags: trunk)
17:34		Further corner-case fixes to the name resolution logic. (Closed-Leaf check-in: 20730bad user: drh tags: name-resolution-fix)
16:54		Remove an incorrect assert() statement (ticket [beba9cae6345a]). Fix other minor problems in the name resolution logic. (check-in: afe96a11 user: drh tags: name-resolution-fix)
00:45		Now supports result sets of the form "TABLE.*" with nested FROM clauses. (check-in: 4cf5ed7e user: drh tags: name-resolution-fix)
2013-01-02
14:57		When resolving result-set name collisions, make them x:1, x:2, x:3, etc. instead of x:1, x:1:1, x:1;1;1. (check-in: ef01e304 user: drh tags: name-resolution-fix)
12:29		Merge all the latest trunk changes into the name-resolution enhancement branch. (check-in: a5f4d2b6 user: drh tags: name-resolution-fix)
2013-01-01
14:01		Reduce the size of the Index object (by 8 bytes on x64). (check-in: 5a2ac944 user: drh tags: trunk)
13:55		Enhance the table_info pragma so that the pk column shows the order of the columns in a multi-column primary key. (check-in: 3076a890 user: drh tags: trunk)
2012-12-31
20:16		More test cases for the REGEXP operator. Fix minor bugs uncovered by these test cases. (check-in: a611c750 user: drh tags: trunk)
19:18		Add the test_regexp.c module containing a cross-platform implementation of the REGEXP operator. (check-in: 46c8c01b user: drh tags: trunk)
2012-12-21
16:15		Ensure the database size field in the db header of a backup database is set correctly. Fix for [0cfd98ee201]. (check-in: ff6857b6 user: dan tags: trunk)
2012-12-20
01:15		Add PRAGMA foreign_key_check. Name the child and parent tables as part of a "foreign key mismatch" error. (check-in: e408dc90 user: drh tags: trunk)
00:32		Remove an unreachable branch operation from the foreign_key_check pragma. (Closed-Leaf check-in: b5a8f316 user: drh tags: foreign-key-check)
2012-12-19
20:39		Version 3.7.15.1 (check-in: 6b85b767 user: drh tags: release, version-3.7.15.1, branch-3.7.15)
17:10		Backport to the 3.7.15 branch the fix to the segfault problem of ticket [a7b7803e8d1e869] which involved the use of "AS" named result columns as logical terms of the WHERE clause. Also, change the version number to 3.7.15.1. (check-in: bae528f4 user: drh tags: branch-3.7.15)
16:58		Fix the segfault problem of ticket [a7b7803e8d1e869] which involved the use of "AS" named result columns as logical terms of the WHERE clause. (check-in: b3c9e8f8 user: drh tags: trunk)
16:32		A couple more test cases. (Closed-Leaf check-in: 0ae14217 user: drh tags: tkt-a7b7803e)
16:25		Additional test cases involving the use of a result column specified by its "AS" name as a logical term of the WHERE clause. Ticket [a7b7803e8d1e8699cd]. (check-in: d7cc364e user: drh tags: tkt-a7b7803e)
15:53		Proposed fix for ticket [a7b7803e8d1e8699cd8a]. (check-in: 3d0e00c7 user: drh tags: tkt-a7b7803e)
13:41		Add commentary to the ExprList object to explain how zSpan is overloaded. Add test cases for the new name resolution functionality. (check-in: 3e7d84db user: drh tags: name-resolution-fix)
02:36		Better resolution of table and column names in joins where some of the terms of the FROM clause are parenthesized. (check-in: 7344e791 user: drh tags: name-resolution-fix)
2012-12-18
19:36		Optimize the degenerate case of a FROM clause table name enclosed all by itself inside parentheses. Generate code as if the parentheses did not exist, rather than the old behavior of manifesting the parenthesized table into a transient table. Also, tag every FROM-clause SELECT subquery that is generated by a parenthesized FROM-clause expression using the SF_NestedFrom flag. The new SF_NestedFrom flag is not yet used for anything. (check-in: 7fecced4 user: drh tags: trunk)
16:07		Resolve names in FROM-clause subqueries prior to resolving names in the result set expressions of a SELECT statement. (check-in: 9b67c633 user: drh tags: trunk)

11:59		On atomic-write capable systems, if copying the contents of an in-memory journal to disk fails, close the (on disk) journal file before returning the error to the caller. This causes the subsequent rollback operation to use the in-memory journal. Fix for [df678d738adb]. (check-in: 8183d8d7 user: dan tags: trunk)
2012-12-17
22:32		Added test cases for PRAGMA foreign_key_check. Fixed a bug that appears when the column order of the child and parent differ. (check-in: 25411f83 user: drh tags: foreign-key-check)
20:57		Add to the foreign_key_check pragma an extra output column "parent" that contains the name of the parent table for the constraint that failed. (check-in: 97f7f737 user: drh tags: foreign-key-check)
20:40		Enhance the error message for "foreign key mismatch" to include the names of the child and parent tables. Begin adding test cases for PRAGMA foreign_key_check. Make sure PRAGMA foreign_key_check gets all necessary table locks. (check-in: 0f996352 user: drh tags: foreign-key-check)
18:43		"PRAGMA foreign_key_check" with no argument checks the foreign keys on all tables. (check-in: 57d47423 user: drh tags: foreign-key-check)
18:05		Fix an issue with child keys that are not INTEGER PRIMARY KEY referencing INTEGER PRIMARY KEY in the parent. (check-in: 603b695b user: drh tags: foreign-key-check)
16:46		Prototype for PRAGMA that checks all foreign key constraints on a table. (check-in: 01c980e9 user: drh tags: foreign-key-check)
2012-12-14
17:54		Optimize IN operators in the WHERE clause of queries using virtual tables. (check-in: 3d65c703 user: drh tags: trunk)
17:48		Remove an unreachable branch. Improvements to comments. (Closed-Leaf check-in: d2fb7619 user: drh tags: vtab-IN-opt)
15:54		Merge in all the trunk changes that have occurred since this branch was opened. (check-in: 6d507e4d user: drh tags: vtab-IN-opt)
15:36		Fix the virtual table IN optimizer so that it work even if the virtual table implementation leaves the sqlite3_index_info.aConstraintUsage[].omit flag clear for an equality constraint that it intends to use. (check-in: d6e045f8 user: drh tags: vtab-IN-opt)
2012-12-13
18:57		Generalize the min/max optimization so that if an appropriate index exists, the index it can be used by any aggregate query that contains only a single max() or min() and does not contain a GROUP BY clause. (check-in: 52e75594 user: drh tags: trunk)
18:51		Increase the version number to 3.7.16 in advance of adding new features for the next release. (check-in: 8bcf5f51 user: drh tags: trunk)
16:37		Attempt to further generalize the min/max optimization so that, if an appropriate index exists, it can be used by any aggregate query that contains only a single aggregate of the form max(colname) or min(colname) and does not contain a GROUP BY clause. (Closed-Leaf check-in: 7280e14c user: dan tags: minmax-opt)
2012-12-12
14:30		Allow the error message from "PRAGMA integrity_check" to be longer than 20,000 bytes. (check-in: 120c82d5 user: drh tags: trunk)
13:36		Version 3.7.15 (check-in: cd0b37c5 user: dan tags: trunk, release, version-3.7.15)
2012-12-11
19:40		Update requirements marks and test cases for multi-VALUE INSERT and to fix typos in requirements text. (check-in: 81d9ee0f user: drh tags: trunk)
19:10		Fix a typo in a comment that is used to generate documentation. No changes to code. (check-in: e38adb60 user: drh tags: trunk)
2012-12-10
22:19		When an arithmetic operation with two integer operands must give a floating-point answer due to overflow, make sure the answer is not rounded back to integer by affinity. (check-in: bd7aeeb6 user: drh tags: trunk)
10:22		Modify releasetest.tcl so that it runs the "checksymbols" test on a build without SQLITE_DEBUG defined. If SQLITE_DEBUG is defined, the sqlite3WhereTrace variable causes the test to fail. (check-in: 75e545a9 user: dan tags: trunk)
09:08		Remove a reference to JumpOnce from a comment in vdbe.c. No code changes. (check-in: ee662c03 user: dan tags: trunk)
2012-12-08
23:37		Pull the latest trunk changes into the sessions branch, and in particular the collating-sequence refactorization. (check-in: 4f6d69ae user: drh tags: sessions)
22:14		Factor some work out of the index loop of the bestBtreeIndex() routine for a small performance increase. (check-in: 92c9ab56 user: drh tags: trunk)
21:51		Refactor collating-sequence handling as a fix for ticket [71e333e7d2e642]. The Expr.pColl field is removed from the Expr object. The COLLATE operator now becomes a separate instance of Expr in the expression tree. The code generator looks up the correct collating function as needed, rather than referring to Expr.pColl. (check-in: 8542e618 user: drh tags: trunk)
21:36		Adjustments to the collating-sequence refactoring to facilitate full-coverage testing and to fix some minor issues found by TH3. (Closed-Leaf check-in: cdbfa664 user: drh tags: ticket-71e333e7)
14:16		Make sure WHERE clause constraints A=B and B=A work the same even with COLLATE clauses. (check-in: b3f53668 user: drh tags: ticket-71e333e7)
13:26		Fix the header comment on the OP_Compare operator. (check-in: 2722f407 user: drh tags: ticket-71e333e7)
06:46		Merge updates from trunk. (check-in: e65db42c user: mistachkin tags: configReadOnly)
04:10		Duplicating check constraint expressions prior to code generation is no longer required, and so it is removed. (check-in: 1a9db8dc user: drh tags: ticket-71e333e7)
03:34		Veryquick passes all tests now. (check-in: 7b96115e user: drh tags: ticket-71e333e7)
00:52		Recognize TK_COLLATE operators that have been transformed into TK_REGISTER. Skip both TK_COLLATE and TK_AS operators when looking for the top of an expression. (check-in: f66c1db2 user: drh tags: ticket-71e333e7)
2012-12-07

21:02		Fix the processing of ORDER BY clauses with COLLATE terms on compound queries. 52 veryquick test failures remain. (check-in: 49654453 user: drh tags: ticket-71e333e7)
20:31		Many more tests are passing. Only about 100 failures remain in veryquick. (check-in: f9fa7581 user: drh tags: ticket-71e333e7)

23:16		In the async VFS, treat the new error code SQLITE_IOERR_DELETE_NOENT as success for xDelete. (check-in: c507ca4a user: mistachkin tags: trunk)
21:16		Remove the Expr.pColl field and compute the collating sequence as it is needed. This fixes the test script "shared9.test", though there is still a memory leak. And there are other problems. Consider this a work-in-progress. (check-in: fd011cb2 user: drh tags: ticket-71e333e7)
20:27		Cherrypick [79ef8e3c77] (Apply the same restrictions on constant refactoring to statements within a trigger program as top-level statements). (Leaf check-in: 34aafb74 user: dan tags: branch-3.7.9)

19:01		Add the SQLITE_FCNTL_TEMPFILENAME file control that asks the underlying VFS to return a new temporary filename. Per request from NSS team at Mozilla. (check-in: 1a63b1d5 user: drh tags: trunk)
15:15		Add a test case that demonstrates ticket [71e333e7d2e642]. (check-in: cc6e0785 user: drh tags: ticket-71e333e7)

16:44		Modify a query in test/thread001.test to ensure that results are returned in the order expected by the test. (check-in: 51cbddd5 user: dan tags: trunk)
14:37		Fixes to a test case in shared_err.test. The fix is to prevent sqlite3_prepare() from being called when the test intends to test the response of sqlite3_step() to an OOM condition. (check-in: 40c14395 user: dan tags: trunk)
14:31		Make sure memory is freed using a routine that is compatible with the routine used to allocate the memory. The SQLITE_MEMDEBUG compile-time option enforces this. (check-in: 9f6c6885 user: drh tags: trunk)
11:30		Since errors are ignored anyway, use sqlite3OsFileControlHint() instead of OsFileControl() to invoke the SQLITE_FCNTL_BUSY_HANDLER file-control. (check-in: bdceca27 user: dan tags: trunk)
10:01		If the atomic-write property is enabled, a transaction may be committed in journal_mode=DELETE mode without ever actually creating a journal file on disk. In this case, do not attempt to unlink() the journal file when committing the transaction. (check-in: 11aa47b0 user: dan tags: trunk)
09:12		Update a couple of test scripts so that they work in auto-vacuum mode. (check-in: 04ab2dc6 user: dan tags: trunk)

17:04		Make sure that the optimization that set the maximum column that will be used on a particular query does not mistakenly change an opcode other than OP_OpenRead or OP_OpenWrite. In particular, make sure it does not overwrite the P4 field of an OP_SorterOpen. (check-in: b0c1ba65 user: drh tags: trunk)
2012-12-01
20:21		Do not exit the command-line shell if a ".read" command invokes a script that contains two errors. But reported on the mailing list. (check-in: 2e5e6515 user: drh tags: trunk)
2012-11-29
14:26		Mark the "async" module as deprecated as its functionality has been superceded by WAL mode. This closes ticket [f46ca03b55ae0e] (check-in: 3d548db7 user: drh tags: trunk)
2012-11-27
21:56		Update the sessions branch to include the SQLLOG enhancement, the SQLITE_IOERR_DELETE_NOENT fix, and a fix for the number-of-documents bug in FTS4. (check-in: ba8d08b6 user: drh tags: sessions)
21:22		Add the SQLLOG capability to trunk. (check-in: f0843f88 user: drh tags: trunk)
21:12		Improved detection of file-does-not-exist in winDelete. (check-in: 92e9b5bc user: drh tags: trunk)

10:56		Fix problems in test_sqllog.c. Clarify the experimental SQLITE_CONFIG_SQLLOG interface. Handle at least the more likely error conditions in test_sqllog.c. (check-in: 429c5b20 user: dan tags: sqllog)
2012-11-26
19:50		Add an option to register global hooks used for logging all SQL executed by an application. (check-in: cd501bbc user: dan tags: sqllog)
2012-11-21
02:10		In winDelete, determine that a file does not exist by checking for a last error of ERROR_FILE_NOT_FOUND or ERROR_PATH_NOT_FOUND. (Closed-Leaf check-in: 692ad3c0 user: mistachkin tags: winNotFound)
2012-11-20
15:06		Have the windows implementation of xDelete return SQLITE_IOERR_DELETE_NOENT if the file to be deleted does not exist. The unix implementation was previously modified to behave this way. The current changes simply brings the two implementations into alignment. (check-in: d4c36d49 user: drh tags: trunk)

11:16		Strive to use posix_fallocate() rather than ftruncate() when posix_fallocate() is available. Ticket [5eaa61ea18]. (check-in: 29980b08 user: drh tags: trunk)
11:08		Use preprocessor macros to automatically detect whether or not posix_allocate() is available. (It is generally available on Linux but not on Mac.) Ticket [5eaa61ea1881040b17449ca043b6f8fd9ca55dc3] (Closed-Leaf check-in: 597333f1 user: drh tags: tkt-5eaa61ea18)
10:54		When available, use posix_fallocate() rather than ftruncate() to allocate space for mmap()ed -shm files, since posix_fallocate() gives an error if no disk space is available whereas ftruncate() is silent and leaves the system vulnerable to a SIGBUS upon first write to the mmap()ed region. Ticket [5eaa61ea1881040b17449ca043b6f8fd9ca55dc3] (check-in: 35625961 user: drh tags: tkt-5eaa61ea18)

01:27		Merge the latest changes from trunk: chiefly the outer/inner loop query optimizer scoring enhancement and the INSTR() function. (check-in: 2993ca20 user: drh tags: sessions)
2012-11-09
21:40		Only log unlink() errors if the error is something other than SQLITE_IOERR_DELETE_NOENT. The error is still reported up the stack, it is simply not added to the sqlite3_log(). (check-in: 5a3b07f0 user: drh tags: trunk)
20:17		Change os_unix.c to propagate ENOENT errors back to sqlite as SQLITE_IOERR_DELETE_NOENT. Have SQLite ignore these where they are benign and propagate them back to the caller where they may indicate a file-system malfunction of some description. (check-in: bed9c172 user: dan tags: trunk)
18:32		Take into account the cost of inner loops when selecting which table of a join to use for the next outer loop. (check-in: 3f87f459 user: drh tags: trunk)
18:22		Disable the table selection rule that tried to prevent full table scans from migrating to the outer loop unless they were optimal. The new scaling of outer-loop costs by cost of inner loops obviates the need for that step. And, in fact, that step causes problems with the new inner-loop cost accounting. (Closed-Leaf check-in: 51bfd63b user: drh tags: inner-loop-cost)

2012-11-05
16:36		Merge the omit-wal-fix branch into branch-3.7.9 where it belongs, and in so doing get branch-3.7.9 working with SQLITE_OMIT_WAL. (check-in: 03919517 user: drh tags: branch-3.7.9)
13:51		Add the INSTR() SQL function. (check-in: a4c181cb user: drh tags: trunk)

14:44		Fix a typo in the header comment for the OpenPseudo opcode. (check-in: 4f106123 user: drh tags: subquery-as-coroutine)
14:39		Make it possible to disable the subquery-by-coroutine optimization using sqlite3_test_control(). Remove an always-false conditional. (check-in: 564631f3 user: drh tags: subquery-as-coroutine)
00:29		Add an optimization that attempts to run a subquery as a coroutine rather than manifesting it into a temporary table. (check-in: 7af3acbb user: drh tags: subquery-as-coroutine)
2012-10-29
14:27		Make the multiplexor and the IntArray extensions callable from C++. (check-in: cbd8fddf user: drh tags: trunk)

15:23		Improvements to the command-line argument parsing in the command-line shell. Command-line options can now occur either before or after the database name and first command and are still accepted and processed. Command-line options are processed even if no database name is given (and :memory: is assumed). (check-in: 317c80cb user: drh tags: trunk)

2012-10-06
03:48		Changes for WinRT compatibility. Also, allow version resource compilation and embedding to be disabled at compile-time. (check-in: 4b0facc1 user: mistachkin tags: trunk)
2012-10-05
19:43		Fix a problem in shared-cache mode where a COMMIT statement might cause a busy-handler belonging to a shared-cache connection other than the current writer to be invoked. (check-in: e0c889d6 user: dan tags: trunk)

15:36		Increase the version number to 3.7.14.1. The version of autoconf used is different from the previous release so there are huge differences in the generated "configure" script. (check-in: 972dbd5f user: drh tags: branch-3.7.14)
12:10		Yet another refactoring of ORDER BY logic in the query planner. This particular check-in works mostly, but still has a few minor issues. (check-in: 8f448745 user: drh tags: qp-enhancements)
2012-10-03
20:25		Merge updates from trunk. (check-in: 1138815c user: mistachkin tags: configReadOnly)

Add test cases to verify correct behavior of the ORDER BY optimization when the covering-index-scan optimization is disabled. Fix a harmless compiler warning in the TCL interface. (check-in: 956e4d7f user: drh tags: trunk)
12:38		Fix a query planner problem that only occurs when covering-index-scan is disabled. Fix to tests whose output changed due to the new and more aggressive ORDER BY optimization. (Closed-Leaf check-in: 0f9bb901 user: drh tags: qp-enhancements)
11:11		Fix the TCL interface so that SQL functions implemented in TCL honor the "nullvalue" setting. Also remove from the TCL interface some unused legacy UTF8 translation code left over from SQLite2. (check-in: 9bf64b66 user: drh tags: branch-3.7.14)
11:02		Fix the TCL interface so that SQL functions implemented in TCL honor the "nullvalue" setting. Also remove from the TCL interface some unused legacy UTF8 translation code left over from SQLite2. (check-in: c1f10a26 user: drh tags: trunk)

22:54		Work around an optimization issue with the MSVC compiler for ARM. (check-in: 7d301fdf user: mistachkin tags: trunk)
15:19		More lenient handling of ORDER BY optimization in joins with mixed ASC/DESC. This is a better and less restrictive fix for the problem addressed by the previous check-in. (check-in: abcf6a5d user: drh tags: trunk)
14:11		Only continue an ORDER BY optimization into inner loops if the equality constraints on the inner loop match terms of an outer ordered index that are actually used by the ORDER BY clause. (check-in: b0e7b4df user: drh tags: trunk)
01:46		Factor an invariant out the loop termination condition for the ORDER BY satisfied-by-index analyzer routine. (check-in: 545bb336 user: drh tags: trunk)

20:32		Fix harmless compiler warnings. (check-in: 59c2be75 user: drh tags: trunk)
20:12		Fix several compiler warnings seen with MSVC. (Closed-Leaf check-in: 8b5f617c user: mistachkin tags: msvcWarnings)
18:44		Add SQLITE_FCNTL_BUSYHANDLER. Invoked to provide access to the busy-handler callback to custom VFS implementations. (check-in: 1262d2f4 user: dan tags: trunk)
17:44		Minor changes to the query planner for improved test coverage. (check-in: c12044df user: drh tags: trunk)
12:44		Omit the sqlite3GetReservedNoMutex() routine in build configurations where it is not used. (check-in: f193dbb6 user: drh tags: trunk)
12:16		Make sure the size parameter to read and write VFS methods in the unix VFS do not become too big or go negative. This was not actually possible in the current code. The checks are added to make sure some future bug does not make it possible. (check-in: daebe3bd user: drh tags: trunk)
06:50		Ensure that the value returned by xSectorSize() is reasonable (currently defined as between 2^5 and 2^16 bytes) before using it to calculate the amount of padding to add to a wal file. (check-in: 6b4ff83b user: dan tags: trunk)
2012-09-29

2012-09-28
20:23		Avoid calling sqlite3BtreeEnter() in a corner case where the corresponding database handle mutex (sqlite3.mutex) may not be held. This prevents a potential deadlock or crash that can occur if the backup API, shared-cache mode and SQLITE_HAVE_CODEC are all in use. (check-in: 89b8c377 user: dan tags: trunk)
18:13		Modify the clearCell function to use SQLITE_CORRUPT_BKPT in the one place it was not. (check-in: 472beb30 user: mistachkin tags: trunk)
13:05		Merge the latest trunk changes (especially "PRAGMA busy_timeout" and the ORDER BY query planner optimizations) into the sessions branch. (check-in: 6ca8eae1 user: drh tags: sessions)
12:55		Update the sessionfault-9.1 and -9.2 tests to account for the change in version 3.7.11 in which a pending statement no longer blocks ROLLBACK but instead causes the next call on that statement to return SQLITE_ABORT. (check-in: fae9eb19 user: drh tags: sessions)
10:57		Merge the latest trunk changes (PRAGMA busy_timeout and the ORDER BY query planner enhancements) into the apple-osx branch. (check-in: 6a5c59dd user: drh tags: apple-osx)
00:44		Query planner enhancements to be more agressive about optimizing out ORDER BY clauses - in particular the query planner now has the ability to omit ORDER BY clauses that span multiple tables in a join. (check-in: 1e874629 user: drh tags: trunk)
2012-09-27
23:27		Fix some corner case behavior in the new ORDER BY optimization logic. Remove the SQLITE_OrderByIdx bit from the SQLITE_TESTCTRL_OPTIMIZATIONS mask, since enabling it caused many TH3 tests to fail when the NO_OPT configuration parameter was engaged, and since there really isn't any need to turn that optimization off. The SQLITE_OrderByIdxJoin bit remains. (Closed-Leaf check-in: 98b63371 user: drh tags: qp-enhancements)
21:03		Modify generation of resource header file for MSVC so that it can work from outside the working directory. (check-in: 20caf80c user: mistachkin tags: trunk)

17:31		Test cases and bug fixes applied to the ORDER BY optimization for joins. Some test cases fail, but except for the new orderby1.test failures, all failures appear to be issues with the tests, not with the core code. (check-in: 75cda864 user: drh tags: qp-enhancements)
15:05		Add more bits to the bit vector that is used to disable optimizations for built-in test. Add specific bit patterns to disable ORDER BY using an index in general and for joins. Use macros to test for bits in the disabled-optimization bit vector, in order to make the code clearer. (check-in: d2fcba1e user: drh tags: qp-enhancements)
14:11		Enable ORDER BY clauses that span joins to be optimized out. (check-in: c29538f9 user: drh tags: qp-enhancements)
12:11		Merge the "PRAGMA busy_timeout" change into trunk. (check-in: 1a679a1e user: drh tags: trunk)
12:05		Further tweaks to the query planner logic in preparation for adding ORDER BY opt-out for joins. (check-in: 53efc10a user: drh tags: qp-enhancements)
2012-09-26
23:17		Further refactoring of the ORDER BY related query-planning logic in order to make it easier to extend to support optimizing out ORDER BY on joins. No actual behavior changes, yet. (check-in: 96496dda user: drh tags: qp-enhancements)
2012-09-25
20:43		Augment the WhereBestIdx structure to pass down into the query planner information that might be used to better detect ORDER BY and DISTINCT optimizations spanning multiple tables of a join. (check-in: 4226e51f user: drh tags: qp-enhancements)
14:29		Pass information around between the major routines of the query planner using a single pointer to a structure rather than a long list of parameters. (check-in: 1104d42e user: drh tags: qp-enhancements)
12:45		Merge updates from trunk. (check-in: 4a470741 user: mistachkin tags: configReadOnly)

15:30		Change the internal sqlite3WhereBegin() to report that the ORDER BY clause is satisfied by indices using the WhereInfo.nOBSat field of the returned structure. (check-in: 22989f35 user: drh tags: trunk)
11:43		Update documentation to describe the threadsafety of sqlite3_enable_shared_cache(). (check-in: e081890c user: drh tags: trunk)
2012-09-21
22:50		Enable query planner tracing using the new (and undocumented) ".wheretrace 1" command in the command-line shell if both the shell and the core are compiled with SQLITE_DEBUG and SQLITE_ENABLE_WHERETRACE. This is not a supported API. Use for testing and debugging only. (check-in: 1be4b16b user: drh tags: trunk)
13:40		Command-line shell enhancements: Added the ".print" command. Enhanced the ".width" command so that negative widths will right-justify. (check-in: a1d8269d user: drh tags: trunk)
00:04		Consolidate more of the DISTINCT processing logic into a single spot in the code. Reduce the number of OP_Column operations needed to perform a WHERE_DISTINCT_ORDERED. (check-in: 79e922f7 user: drh tags: trunk)
2012-09-20
15:41		Continuing incremental enhancements of SELECT code generation: Remove the Select.affinity field. Use SelectDest.affSdst instead. (check-in: cf40b7b5 user: drh tags: trunk)
14:26		Refactoring of DISTINCT code. Change the name of the local variable "distinct" to "distinctTab". Generate cleaner code w/o unnecessary P4 and P5 values on the OP_Null for WHERE_DISTINCT_ORDERED. (check-in: 0cda241a user: drh tags: trunk)
2012-09-19
21:15		Tighter VDBE code for the WHERE_DISTINCT_ORDERED case of DISTINCT keyword handling. (check-in: 94b48064 user: drh tags: trunk)

00:35		Merge the covering-index-scan optimization into trunk. (check-in: ddd5d789 user: drh tags: trunk)
2012-09-18
23:21		Silence harmless compiler warning seen with SQLITE_OMIT_DEPRECATED. (check-in: c5cee969 user: mistachkin tags: trunk)
19:29		Enhance IN processing to allow efficient use of indices with numeric affinities. Add test cases for IN processing that would have spotted the error in the [2be661a48023f4] check-in. (check-in: 5ded9b68 user: drh tags: trunk)
17:32		This change generates incorrect code when there are two or more IN operators in the WHERE clause that are both used by the same index. Was: Omit an unnecessary OP_IfNull that immediately follows an OP_Rowid. (Closed-Leaf check-in: 2be661a4 user: drh tags: mistake)
17:08		Enhancements to the comments on sqlite3FindInIndex(). No code changes. (check-in: b1a4c394 user: drh tags: trunk)
14:00		Add the stack_usage.tcl script for analyzing the output of objdump on the amalgamation and estimating the sizes of stack frames on each function. (check-in: 030013ff user: drh tags: trunk)
13:20		Update the vdbe-compress.tcl script so that it accepts variable declarations inside of #ifdef...#endif. This enhancement is needed due to the change of check-in [39866c0ede5d6ef4]. (check-in: e7db056a user: drh tags: trunk)
2012-09-17
21:24		Make sure the WHERE_IDX_ONLY flag is not set on query plans that will not be using an index. (Closed-Leaf check-in: 698b2a28 user: drh tags: fullscan-covering-index)
20:44		Add the ability to disable the covering-index-scan optimization at compile-time, start-time, or at run-time. Add test cases to check this configurability. (check-in: ccb8ecc3 user: drh tags: fullscan-covering-index)
19:26		Merge recent trunk changes into the fullscan-covering-index branch. (check-in: 1c0bf030 user: drh tags: fullscan-covering-index)
19:12		Remove obsolete bits from the bitvector that defines disabled optimizations in the SQLITE_TESTCTRL_OPTIMIZATIONS verb of sqlite3_test_control(). (check-in: 4c21ee2d user: drh tags: trunk)
18:56		Remove an unnecessary parameter from sqlite3Utf8Read() resulting in a slight performance increase. (check-in: 8b962c94 user: drh tags: trunk)
17:16		Make sure the KeyInfo.aSortOrder array is always allocated so that we never have to test for KeyInfo.aSortOrder==0 in performance-critical loops. (check-in: 45793f0b user: drh tags: trunk)
15:36		Performance enhancement in the sqlite3VdbeSerialType() routine. (check-in: ad298f52 user: drh tags: trunk)
2012-09-15
18:45		Attempt to use a covering index even on a full table scan, under the theory that the index will be smaller and require less disk I/O and thus be faster. (check-in: cfaa7bc1 user: drh tags: fullscan-covering-index)
13:39		Make sure the name of rollback journal files are double-zero terminated when they are passed into the VFS. (check-in: 8711a844 user: drh tags: trunk)
13:29		Factor out the code that generates a co-routine for evaluating the SELECT on the RHS of an INSERT statement so that the same code can potentially be reused in other places. (check-in: a93ee09c user: drh tags: trunk)
2012-09-13

2012-08-08
14:04		When populating an index b-tree as part of a CREATE INDEX or REINDEX statement, distribute cells between up to three siblings in balance_nonroot() instead of four. This produces identical database files, but is slightly faster. (check-in: b0d31e77 user: dan tags: trunk)

18:50		When reusing pages as part of creating a new index, allocate the leaves from each free-list trunk page in ascending order, instead of trying to maximize localization for each individual allocation. This increases the chance that pages will be written to disk in ascending order by a large CREATE INDEX statement, improving overall performance.

14:23		Add the ieee754() SQL function that interprets a blob as a big-endian double. Arrange for the quote() SQL function to emit ieee754() functions in its output so that floating-point values in the database are exactly preserved by a ".dump" command in the shell. (Closed-Leaf check-in: 87597e98 user: drh tags: ieee754-func)
08:00		Fix a few compilation issues that can occur with certain compilers (e.g. GCC 2.95.3, MSVC). (check-in: f970a3de user: mistachkin tags: compiler-compat)
2012-06-16
15:26		In Lemon, when comparing the output to the *.h file to see if it has changed, make sure that the proposed new output and the preexisting output are the same size before deciding that they are the same. (check-in: 0c2fb18d user: drh tags: trunk)
2012-06-15
20:42		Fix compiler warning. (Closed-Leaf check-in: 37d9bc06 user: mistachkin tags: deferred-close)

07:24		Fix a malloc/free mismatch in pager.c (sqlite3_free() called on a buffer allocated by sqlite3DbMalloc()). (check-in: 506008f0 user: dan tags: trunk)
02:35		Provide an (undocumented) compile-time option to disable the page cache overflow counter, in order to avoid a mutex. (check-in: 208825cd user: drh tags: trunk)
2012-06-06
23:59		Fix harmless Clang warnings. (check-in: 31fe1985 user: drh tags: trunk)
23:25		Fix an #if that is applicable to WinRT, even thought it is currently disabled by another #if. (check-in: baa8b783 user: mistachkin tags: trunk)
23:23		Merge the changes need to compile on WinRT into trunk. (check-in: 61360ca6 user: drh tags: trunk)
19:51		Disable FTS unicode61 by default. It is enabled by specifying compile time option SQLITE_ENABLE_FTS4_UNICODE61. (check-in: eccd6b65 user: dan tags: trunk)
19:30		Have the FTS unicode61 strip out diacritics when tokenizing text. This can be disabled by specifying the tokenizer option "remove_diacritics=0". (check-in: 790f76a5 user: dan tags: trunk)
19:01		Avoid resetting the shared-cache schema when on of the connections using the shared cache closes. Delay resetting the schema until the last connection closes. (check-in: 635e3a76 user: drh tags: trunk)
10:56		Make sure the Index.azColl pointers do not point to connection-specific memory. Also, remove an unnecessary reinitialization to sqlite3.pDfltColl. (Closed-Leaf check-in: c469850b user: drh tags: shared-schema)
2012-06-05
19:20		Merge the latest trunk changes into shared-schema branch. Also fix a C99-ism in that branch. (check-in: 42338e9e user: drh tags: shared-schema)

05:18		When not compiling for WinRT, skip using a couple Win32 APIs unavailable when compiling with MinGW. (check-in: eb29e2d9 user: mistachkin tags: winrt)
2012-06-02
17:09		Revert sqlite3_close() to legacy behavior. Create a new sqlite3_close_v2() interface that exhibits the deferred-close behavior. This minimizes the chance of breakage in legacy apps. (check-in: c4b86211 user: drh tags: deferred-close)
14:32		The sqlite3_close() interface returns SQLITE_OK even if there are outstanding sqlite3_stmt and sqlite3_backup objects. The connection becomes a zombie. Resource deallocation is deferred until the last sqlite3_stmt or sqlite3_backup object closes. This is intended to help SQLite play nicer with garbage collectors. (check-in: e276a02b user: drh tags: deferred-close)
2012-05-31
22:12		Update several APIs to enable compilation with newer revisions of WinRT. (check-in: 54de739f user: mistachkin tags: winrt)

00:21		Only call fchown when running as root and supporting files mismatch the database owner & perms (check-in: ed53b645 user: adam tags: apple-osx)
2012-05-29
19:25		Link the NDEBUG macro to SQLITE_DEBUG so that when SQLITE_DEBUG is defined, NDEBUG is automatically undefined an dwhen SQLITE_DEBUG is undefined NDEBUG is automatically defined. (check-in: 07935d10 user: drh tags: trunk)
17:59		Fix a typo (a repeated "or") in the documentation. No changes to code. (check-in: 6fec6cf1 user: drh tags: trunk)
17:02		Changes some NDEBUG macros to SQLITE_DEBUG in os_unix.c. The is a notational change only and really should not effect the code. (check-in: 8e302570 user: drh tags: trunk)
00:48		Merge the 64-to-32-bit RTree rounding fixes from trunk into the sessions branch. (check-in: 7eff45c2 user: drh tags: sessions)
00:39		In the RTree module, make sure all double-to-float conversions round in a direction to increase the size of element bounding boxes. (check-in: 0abdc290 user: drh tags: trunk)
00:30		Refactor the float-to-double rounding routines so that they compile without warnings. (Closed-Leaf check-in: f607ad27 user: drh tags: rtree-32bit-rounding)
2012-05-28
20:22		Fix the MSVC makefile so that it works with the unicode61 tokenizer. (check-in: 48015814 user: drh tags: trunk)
20:16		Simplification to the coordinate rounding logic in RTree. (check-in: df24072d user: drh tags: rtree-32bit-rounding)
19:19		When converting 64-bit floating point coordinates to 32-bit in RTree, take care to round the values such that the size of the bounding box is enlarged. (check-in: f4e8ff03 user: drh tags: rtree-32bit-rounding)
18:22		Merge the unicode61 tokenizer and the shared-cache-memory database changes into the sessions branch. (check-in: df817e70 user: drh tags: sessions)
17:51		Updates regarding URI query parameters and shared cache in the documentation derived from comments in sqlite.h.in. No changes to code. (check-in: bcc72d41 user: drh tags: trunk)
15:32		Fix Makefile.in so that it works with the new unicode tokenizer of FTS3/4. Update the version number to 3.7.13. (check-in: b8720d04 user: drh tags: trunk)
13:58		Add the mode=memory option to URI filenames, which when present forces the database to be an in-memory database. This enables named in-memory databases. (check-in: 651520fa user: drh tags: trunk)
12:22		Omit the fts3 unicode character class routines from the build if fts3/4 is disabled. (check-in: c00bb5d4 user: drh tags: trunk)
2012-05-27
22:42		Merge into trunk the changes that permit :memory: databases to use shared cache. (check-in: e72179f3 user: drh tags: trunk)
01:19		Have user interfaces report out the filename of in-memory databases as an empty string, as it always has. This simplifies the changes. (Closed-Leaf check-in: 595dfdbf user: drh tags: shared-cache-memdb)
00:11		Fix corner-case problems with shared-cache for in-memory databases. (Closed-Leaf check-in: 997ef5f6 user: drh tags: shared-cache-memdb)
2012-05-26
20:08		Only allow :memory: databases to share cache if there are created using a URI filename. This minimizes the risk of breakages in legacy applications that have shared-cache enabled but also use :memory: databases which they expect to keep separate. (check-in: e3ad61e0 user: drh tags: shared-cache-memdb)
18:42		Merge fts4-unicode branch with trunk. (check-in: 25ba1f84 user: dan tags: trunk)
18:28		If SQLITE_DISABLE_FTS3_UNICODE is defined, do not build the "unicode61" tokenizer. (Closed-Leaf check-in: e71495a8 user: dan tags: fts4-unicode)
18:06		Enable the use of shared cache for an in-memory database, so that separate database connections can share the same in-memory database. (check-in: 4590e433 user: drh tags: shared-cache-memdb)
17:57		Change the format of the tables used by sqlite3FtsUnicodeTolower() to make them a little smaller. (check-in: b89d3834 user: dan tags: fts4-unicode)

19:50		Add special fast paths to sqlite3FtsUnicodeTolower() and Isalnum() for codepoints in the ASCII range. (check-in: cf7b25d4 user: dan tags: fts4-unicode)
18:48		Fix comments in generated file fts3_unicode2.c. (check-in: 3dc567ef user: dan tags: fts4-unicode)
17:50		Add an experimental tokenizer to fts4 - "unicode". This tokenizer works in the same way except that it understands unicode "simple case folding" and recognizes all characters not classified as "Letters" or "Numbers" by unicode as token separators. (check-in: 0c13570e user: dan tags: fts4-unicode)
2012-05-22
19:25		Use the new test suite helper procedure 'get_pwd' to query the current directory from tests. (check-in: 1dd01e40 user: mistachkin tags: winrt)

19:11		Convert the NameContext object from using u8 booleans to using individual bits in a single u8 as its booleans. This change might become a basis for a fix for [c2ad16f997ee9c]. (check-in: 72226096 user: drh tags: nested-agg)
16:59		Make sure lookaside memory allocations are unusable after they are freed. (check-in: 3869aef6 user: drh tags: trunk)
12:25		Move some #defines earlier in the file for test_quota.c in order to avoid a use before definition. (check-in: fda1ea0b user: drh tags: trunk)
05:02		Allow the sqlite3ExplainBegin function to be compiled by MSVC. (check-in: 18555128 user: mistachkin tags: trunk)
03:15		Change the ".schema" command of the shell to output VIEWs in declared order, rather than alphabetical order, so that nested views will appear in the correct order. Fix for ticket [cfe84e86839e59e8]. (check-in: e092ff69 user: drh tags: trunk)
2012-05-20
20:23		Fix a test case so that it works even with very long pathnames. (check-in: ecd4a063 user: drh tags: trunk)
20:14		Check-in included unrelated debugging code by mistake. Was: Fix a test case in the shell1.test script so that it works even for very long pathnames. (Closed-Leaf check-in: 0c0a0398 user: drh tags: mistake)
2012-05-17
21:04		Merge updates from trunk. (check-in: 224c65e4 user: mistachkin tags: winrt)
14:17		Stylistic fixes: limit source code line length to 80 characters. C89-style comments only, not C++/C99 style. (check-in: 4068abe0 user: drh tags: apple-osx)

2012-05-15
18:28		The former sqlite3ResetInternalSchema() routine was really two different routines, selected by parameter, each with a confused mission. So split this routine up into three separate smaller routines, calling each separately as needed. Hopefully this will make further refactoring and schema reset collateral damage containment easier. (check-in: aa0c3493 user: drh tags: shared-schema)
17:15		When a connection disconnects from a shared-cache database, only delete the in-memory schema if there are no other connections. (check-in: 46f4eb54 user: dan tags: shared-schema)

01:08		Enhance the do_test proc in the test suite so that if the expected result is of the form "/.../" or "~/.../" then regular expression matching is done between result and the "..." part of the expectation. In the ~/.../ case, we expect there to be no match. (check-in: c9a73440 user: drh tags: trunk)
2012-04-26

2012-04-21
11:33		If terminating interactive input to the command-line shell with ^D, issue an extra \n to move the cursor to the next line before exiting. This check-in also accidently adds the test_spellfix.c file to the source tree. (check-in: feff1ef0 user: drh tags: trunk)
00:31		Merge the latest trunk changes into the WinRT branch (fixes for tickets [2a5629202f] and [385a5b56b9]). (check-in: 25478dcf user: mistachkin tags: winrt)

18:42		Fix a problem with NULL handling in aggregate min/max when returning values from the row containing the min or max. (Closed-Leaf check-in: f27c7b4f user: drh tags: output-minmax-row)
17:35		For queries of the form "SELECT p, max(q) FROM t1", the value of column p returned is the one on the same row that holds the maximum value of q. (check-in: adb29232 user: drh tags: output-minmax-row)

20:43		Only invalidate the schema when the OP_ParseSchema opcode fails, not on any general failure of a vdbe program. (check-in: 11f68d99 user: drh tags: trunk)
16:29		Fix an FTS problem triggered by querying for an N character prefix using an N+1 character prefix index after rows have been deleted from the FTS table. Fix for [edb497982c]. (check-in: c05c3fd2 user: dan tags: trunk)
2012-01-24
10:08		Changes to the async-io module so that the xFileControl method returns SQLITE_NOTFOUND when a file-control is not recognized and so that it adds the second nul-terminator byte to filenames passed to the xOpen method of the underlying VFS. (check-in: 7036886e user: dan tags: trunk)
2012-01-20
15:05		Cherrypick the fix from [629108c8e5376f989] into the nx-devkit branch. (check-in: d7374568 user: drh tags: nx-devkit)
2012-01-19
16:57		Make the use and function of SQLITE_DYNAMIC clearer. Add assert() statement to help ensure that SQLITE_DYNAMIC is not misused. (check-in: ab80f2c3 user: drh tags: trunk)
2012-01-18
18:22		Avoid overriding the malloc_usable_size symbol using the C preprocessor as this might be confusing the build on some systems. (check-in: bbaec351 user: drh tags: trunk)
12:46		Add the SQLITE_WITHOUT_MSIZE and SQLITE_WITHOUT_ZONEMALLOC macros in mem1.c to disable the use of _msize() on windows and the zone memory allocator on Apple products, respectively. (check-in: 238e35a4 user: drh tags: trunk)
01:14		Remove a redundant assignment from the VM. (check-in: d0dabe2f user: drh tags: trunk)
01:09		Fix typo in comment. (check-in: 199edb68 user: mistachkin tags: trunk)
2012-01-17

2012-01-16
16:56		Enhance the command-lin shell to interpret CSV files as described by the wikipedia article on CSV. (check-in: 93aa17d8 user: drh tags: trunk)
16:39		Test the fts4 content and prefix options together. (check-in: de11cd5c user: dan tags: trunk)
13:28		Version 3.7.10 (check-in: ebd01a8d user: drh tags: trunk, release, version-3.7.10)
13:00		Rebuild the configure script using autoconf 2.68 since autoconf 2.65 (previously used) appears to build incorrect scripts for Mac. (check-in: 9da1cd0a user: drh tags: trunk)
12:33		Support building with SQLITE_ENABLE_SESSION under MSVC. (check-in: 2845654d user: mistachkin tags: sessions)
2012-01-14
14:13		Merge the latest trunk changes into the apple-osx branch. (check-in: 2cc414cd user: drh tags: apple-osx)

03:34		Make sure the EXTERN macro is properly defined when building targets that require it (e.g. on MinGW). (check-in: 88ad2f23 user: mistachkin tags: trunk)
00:42		In the multiplexor routine that determines the size of an overflow file, return 0 and leave the error code unchanges if there were prior errors. This prevents some I/O errors from going unreported in nx-devkit tests. (check-in: 6da0821a user: drh tags: trunk)
2012-01-13
16:48		Fix documentation typos. No changes to code. (check-in: 0b857613 user: drh tags: trunk)

15:50		Update the documentation for the sqlite3_uri_*() routines to make it clear that there argument must be a database filename passed into xOpen(). No changes to code. (check-in: 08230a3a user: drh tags: trunk)
15:21		Fix backup2.test so that it passes on OpenBSD (which produces a slightly different error message in one case). (check-in: 227cfe11 user: dan tags: trunk)
14:50		Do not throw an error from within test_journal.c if a database file size is not an integer multiple of the page-size. (check-in: 3f4899a9 user: dan tags: trunk)
10:51		Omit test file zerodamage.test from the inmemory_journal permutation. (check-in: 0c0051b1 user: dan tags: trunk)
10:04		Fix test case issues related to errors in file-controls and the PSOW flag. (check-in: 5afbcd49 user: dan tags: trunk)
2012-01-12
16:41		Fix issues in test cases so that they work with DEFAULT_AUTOVACUUM defined. And with a small default cache-size. (check-in: a298465c user: dan tags: trunk)
15:05		Fix typos in a testcase() macro introduced by the previous commit. (check-in: 0467742f user: dan tags: trunk)
14:25		Remove some assert() statements that can fail with corrupt databases. (check-in: 7654ae71 user: dan tags: trunk)
2012-01-11
16:16		Remove code made unreachable by the enhancement of the previous check-in. (check-in: 9e31a275 user: drh tags: trunk)
15:47		Make the pager less vulnerable to problems caused by shifting sector sizes when rolling back a hot journal. (check-in: 629108c8 user: drh tags: trunk)
11:20		Fix the sqlite3_quota_file() function in test_quota.c so that it adds the second nul-terminator to all file names that will be passed to a VFS xOpen method. (check-in: 3013f9a6 user: dan tags: trunk)
01:01		Prevent winOpenSharedMemory from masking the real return code from its call to winOpen. Also, add asserts to check the double-zero termination of database file names. (check-in: 93a65776 user: mistachkin tags: trunk)
00:38		Make sure filenames handed to the VFS by the fake_big_file test procedure are double-zero terminated. (check-in: d0a86860 user: drh tags: trunk)
2012-01-10
23:18		Only require double-zero terminators on database filenames, not any every files supplied to the xOpen method. This backs out [2544f233f1]. Also refactor the fillInUnixFile() routine in os_unix.c to reduce the number of parameters. (check-in: cb774b26 user: drh tags: trunk)
17:59		Refactor sqlite3OsFileControlNoFail() into sqlite3FileControlHint(). (check-in: 722735a4 user: drh tags: trunk)
17:28		Avoid passing strings with a single nul-terminator (two are required) to the VFS xOpen() method from within the code that checks to see if a master-journal file may be safely deleted. (check-in: 2544f233 user: dan tags: trunk)
16:56		Add function sqlite3OsFileControlNoFail(), which is the same as sqlite3OsFileControl() except that it does not simulate OOM errors. This saves adding calls to the BenignMalloc() functions around each of the invocations of sqliteOsFileControl() that ignore the return code. (check-in: af59b182 user: dan tags: trunk)
16:40		Check the return code from sqlite3OsFileControl() in sqlite3BtreeCopyFile() and report any errors that it generates. (check-in: 7f852ac6 user: drh tags: trunk)
00:24		Remove the BenignMalloc() from around the call to FCNTL_OVERWRITE. Add new ones around sqlite3OsDelete(). Fix an assert that causes problems for the nx-devkit. (check-in: 38bc4236 user: drh tags: trunk)
2012-01-09
14:57		Cherry-pick the fix to surplus overflow files in the multiplexor, check-in [1238619756c0c] in the trunk. (check-in: 2f8c62c3 user: drh tags: nx-devkit)
14:19		Cosmetic changes to lemon. No changes to core functionality nor impact on SQLite. (check-in: 393fc78a user: drh tags: trunk)
13:41		Make sure the multiplexor does not create unnecessary overflow files. (check-in: 12386197 user: drh tags: trunk)
11:37		Have test_multiplex.c add a second nul-terminator byte to the strings that it passes to the xOpen method of the underlying VFS, in case that VFS passes the string to sqlite3_uri_parameter() or similar. (check-in: 12f5b8c9 user: dan tags: trunk)
2012-01-08
22:18		Fix typos in commands. Combine the ExpandBlob and expandBlob macros into one. (check-in: fc9179e1 user: drh tags: trunk)
12:32		Make sure the shared-memory filename sythesized by os_win.c is double-zero terminated, so that it can be used with sqlite3_uri_parameter(). (check-in: 429380f9 user: drh tags: trunk)
00:54		Fix harmless compiler warning seen with MSVC. (check-in: 9612bcd6 user: mistachkin tags: trunk)
2012-01-07
15:17		Fix a bug in lemon in computation of which non-terminals can generate an empty string. This bug and the fix make absolutely no difference for the grammar used by SQLite, but it can make a difference when lemon is used in other grammars. (check-in: ce32775b user: drh tags: trunk)
2012-01-06
13:58		Add missing finish_test to the end of the zerodamage.test module. Disable the zerodamage module if virtual tables are omitted from the build. (check-in: d2a5685b user: drh tags: trunk)
2012-01-05
23:32		Combine various boolean variables in the BtShared structure into a single boolean vector. Also make performance improvement simplifications to sqlite3BtreeMovetoUnpacked(). (check-in: 11949331 user: drh tags: trunk)
21:19		Make sure the name of the shared memory file has two zero-terminators in the UNIX VFS, so that sqlite3_uri_parameter() will work correctly on that name. (check-in: 3d088ba5 user: drh tags: trunk)
18:33		Fix an incorrect assert() on the sqlite3FileSuffix3() function. (check-in: 24db54bd user: drh tags: trunk)
16:07		Change the unix VFS so that it ignores all but the least-significant bit of the syncDir flag to xDelete. Add an assert to prove that the core only ever uses that one bit. (check-in: e75fd3b2 user: drh tags: trunk)
13:02		Merge all of the latest trunk changes into the sessions branch. (check-in: a9bcb432 user: drh tags: sessions)
12:38		Ensure 8-byte alignment of Index.aiRowEst elements even if the size of an Index object is not a multiple of 8 bytes. (check-in: 1378f905 user: drh tags: trunk)
11:43		Remove the SQLITE_FCNTL_SYNC_OMITTED cases from the unix and windows VFSes as they are no longer needed because of check-in [fd3822f1f2]. (check-in: 7cf568a1 user: drh tags: trunk)
2012-01-04
12:57		Fix typos and comments and make minor changes to a few function names, as suggested by readership. (check-in: e9d05cbb user: drh tags: trunk)
2012-01-03
21:54		Pull all the latest trunk changes over into the apple-osx branch. (check-in: 8a048423 user: drh tags: apple-osx)
21:33		Experimental changes to prevent buffer overreads when parsing a corrupt database file. (Closed-Leaf check-in: 9e5add51 user: drh tags: no-overread)
14:50		Make sure filenames passed into sqlite3OsOpen() always have the extra zero-terminators needed by sqlite3_uri_parameter(). (check-in: d73e93cf user: drh tags: trunk)
2012-01-02
18:20		Remove the code that attempts to find the sector size from the OS and hardcode the xSectorSize methods of the unix and windows VFSes to return SQLITE_DEFAULT_SECTOR_SIZE, which is now set to 4096 unless overridden. (check-in: 03d8362c user: drh tags: trunk)
18:00		Change page quantities in pcache1.c to unsigned. (check-in: da52e6e8 user: drh tags: trunk)
16:38		Remove an incorrect assert() in btree.c. (check-in: c1691d99 user: drh tags: trunk)
15:45		Make sure large negative arguments to PRAGMA cache_size do not cause 32-bit signed integer overflow. Also correct a requirements mark. (check-in: 17c30634 user: drh tags: trunk)
14:50		Have SQLITE_FCNTL_SYNC_OMITTED use the normal method of returning an error code. (check-in: fd3822f1 user: dan tags: trunk)
12:41		Fix the build so that it works when SQLITE_ENABLE_8_3_NAMES=1. (check-in: d9761f15 user: drh tags: trunk)
2012-01-01
13:58		Tweaks to improve testability. (check-in: e3a929e4 user: drh tags: trunk)
2011-12-31

2011-12-30
18:16		Add calls to the BenignMalloc() functions around the SQLITE_FCNTL_SIZE_HINT call in pager.c. (check-in: c17a3f5e user: dan tags: trunk)
16:16		Fix a typo in the documentation for PCACHE2. No changes to code. (check-in: 46e7903a user: drh tags: trunk)
16:09		Change dbstatus.test to account for the fact that the value reported by DBSTATUS_SCHEMA_USED may be slightly lower than the actual memory used on osx (check-in: 6f2010c8 user: dan tags: trunk)
16:07		Fix up requirements marks for syntax diagrams to reflect the new and improved GIF renderings. (check-in: 1bb23a3b user: drh tags: trunk)
15:17		Update the text of requirements associated with sqlite3_pcache_methods2. Update requirements marks embedded in code. All of the above are comment changes only; there are no changes to code in this check-in. (check-in: f945c41a user: drh tags: trunk)
11:43		Hold the database handle mutex for the duration of sqlite3_db_release_memory(). (check-in: eeaf2988 user: dan tags: trunk)
10:54		Minor changes to fix compilation with SQLITE_OMIT_WAL and SQLITE_OMIT_WSD defined. (check-in: 26a513a8 user: dan tags: trunk)
09:00		Change an implicit i64-to-int cast in pager.c to an explicit cast. (check-in: 6a71ba9c user: dan tags: trunk)
05:08		Fix some typos in comments. No code changes. (check-in: 4edc5994 user: dan tags: trunk)
2011-12-23
20:49		Documentation updates. No changes to code. (check-in: a8a1a639 user: drh tags: trunk)
13:32		Avoid excess syncs when padding a transaction in a WAL. (check-in: 1f24ae71 user: drh tags: trunk)
11:07		Fix a problem with [f9c4a7c8f4] as applied to this branch. (Leaf check-in: e6a04bf9 user: dan tags: branch-3.7.6)
02:07		Merge the POWERSAFE_OVERWRITE features and the use of statvfs() from the statvfs branch into trunk. (check-in: 2370d70e user: drh tags: trunk)
01:04		Change the name ZERO_DAMAGE to the more descriptive POWERSAFE_OVERWRITE. The query parameter used to control this device characteristic is now "psow". (Closed-Leaf check-in: 6191c5e4 user: drh tags: statvfs)
00:25		Merge the latest trunk changes into the statvfs branch. (check-in: d5e36327 user: drh tags: statvfs)
00:07		Add interfaces sqlite3_uri_boolean() and sqlite3_uri_int64() which are wrappers around sqlite3_uri_parameter() combined with internal routines for converting strings to booleans and 64-bit integers. (check-in: 83d26b9a user: drh tags: trunk)
2011-12-22
18:44		Backport the fixes for Coverity-discovered problems in [1c27d84216], [676acce274], and [f9c4a7c8f4] from trunk to the 3.7.6 branch. (check-in: a61786e7 user: drh tags: branch-3.7.6)
17:31		Fix minor issues with FTS and RTREE discovered by coverity. (check-in: 1c27d842 user: drh tags: trunk)
17:10		Check the return code from sqlite3_initialize() called from within sqlite3_soft_heap_limit64() and return an error from sqlite3_soft_heap_limit64() if sqlite3_initialize() fails. (check-in: 676acce2 user: drh tags: trunk)
15:30		Fix a problem in fts3_write.c causing stack memory to be referenced after it is out of scope. (check-in: f9c4a7c8 user: dan tags: trunk)
02:10		Merge recent trunk changes into the statvfs branch. (check-in: 995ec8a4 user: drh tags: statvfs)
01:46		Remove a redundant assignment operator. (check-in: 19a6852a user: drh tags: statvfs)
2011-12-21
23:38		Cherry-pick the SQLITE_DIRECT_OVERFLOW_READ fix for ticket [ac0ff496b7e] of changes [c5256b59ad] and [c723e3e18a] into the nx-devkit branch. (check-in: 42f31f19 user: drh tags: nx-devkit)
18:04		Fix other problems where 32-bit integer overflow may cause a problem. Two that require an improbably large sub-journal and two in test harness code. Ticket [ac0ff496b7e2] (check-in: c723e3e1 user: dan tags: trunk)
17:00		Avoid 32-bit overflow when calculating the byte offset of an overflow page in SQLITE_DIRECT_OVERFLOW_READ code. Fix for [ac0ff496b7]. (check-in: c5256b59 user: dan tags: trunk)
14:42		Add the ability to enable or disable SQLITE_IOCAP_ZERO_DAMAGE using a URI parameter for both unix and windows. Add a file-control to query or disable the ZERO_DAMAGE setting. Add the -uri option to the "sqlite3" TCL command in tclsqlite3.c. Allow the sqlite3_uri_parameter() interface to accept a NULL pointer for its first parameter. (check-in: c83627b7 user: drh tags: statvfs)
2011-12-20
22:18		Remove the code that tries to detect OOO header writes on a WAL recovery. The code is made obsolete by syncing the WAL header. (check-in: 7ac713a1 user: drh tags: statvfs)
20:13		Refactor the sqlite3WalFrames() routine for clarity of presentation. Do the padded transaction sync as the write pointer crosses the final sector boundary instead of at the end, for efficiency. Always sync the WAL header immediately after it is written. (check-in: 92c73b42 user: drh tags: statvfs)
13:13		Assert that the isCommit parameter to sqlite3WalFrames() is zero if and only if the nTruncate parameter is zero. (check-in: 979daf92 user: drh tags: trunk)
2011-12-19
15:46		Add test for WAL mode to unixexcl.test. (check-in: 4d518bd4 user: dan tags: trunk)
11:57		Merge [21b76af6ed] into statvfs branch. (check-in: e694f7b1 user: dan tags: statvfs)
11:16		Fix a couple of test cases to account for the master-journal name related change in [cf3bccc2]. (check-in: 21b76af6 user: dan tags: trunk)
10:07		Modify test cases to account for the ZERO_DAMAGE change. (check-in: 68684495 user: dan tags: statvfs)
00:31		Some fixes to the test suite so that it works with ZERO_DAMAGE set to true. Still lots more problems remain. (check-in: 41891b23 user: drh tags: statvfs)
2011-12-17
20:02		For improved clarity of presentation, refactor some of the code associated with ZERO_DAMAGE and sector-size. (check-in: 1dde96c9 user: drh tags: statvfs)
19:49		Add SQLITE_IOCAP_ZERO_DAMAGE and enable it for both unix and windows. Use this device characteristic to reduce the required work in journaling. A side effect is that this changes the default page exists back to 1024 even with the use of statvfs(). (check-in: a0be6ea4 user: drh tags: statvfs)
16:25		Fix a bad #endif with the previous check-in on this branch. (check-in: 915713ff user: drh tags: statvfs)
16:09		Add support for statvfs() in os_unix.c, for determining the sector size. This causes many TCL test failures under Linux. (check-in: e0d44450 user: drh tags: statvfs)
13:45		Merge in changes that cause the first sector of the WAL file to be synced when the WAL restarts. This is a fix for the power-loss corruption problem described in ticket [ff5be73dee086] (check-in: 44ca4d12 user: drh tags: trunk)
08:10		Add tests to walcrash3.test. (check-in: d7688042 user: dan tags: trunk)
01:31		Make sure the Salt-1 value in the WAL file is sequentially numbered at each checkpoint, as it says it should be in the documentation. (check-in: 7b63b11b user: drh tags: trunk)
2011-12-16
21:26		Enhance the WAL header sync so that it honors the various synchronous pragmas, settings, and device characteristics. (Closed-Leaf check-in: 9799241f user: drh tags: wal-header-sync)
19:34		Proposed changes that ensure that the WAL header is written prior to the first commit mark. (check-in: 91d0437c user: drh tags: wal-header-sync)
17:01		Add code for a test that was failing before the persistent-wal related changes of [09ccc4a1be]. (check-in: 49d21ce5 user: dan tags: trunk)
15:38		Merge the fix for [a1fa75cbdd02] from the experimental branch. Also fix the persistent-wal mode feature of truncating the WAL on close so that it always truncates the WAL to zero bytes. (check-in: 09ccc4a1 user: drh tags: trunk)
15:11		Improved logging of master-journal name conflicts. (check-in: b1005ef4 user: drh tags: trunk)
13:42		Merge the nx-devkit changes into trunk. (check-in: cf3bccc2 user: drh tags: trunk)
13:24		Experimental fix for [a1fa75cbdd]. (Closed-Leaf check-in: 6492af76 user: dan tags: experimental)
05:50		Tweaks to the way multiplexSubOpen() works, for backwards compatibility. (check-in: bb403388 user: drh tags: nx-devkit)
05:09		Fix a potential infinite loop (inserted by the previous check-in) on the multiplexWrite() method of the multiplexor. (check-in: 022bf427 user: drh tags: nx-devkit)
04:57		The xTruncate method for the multiplexor now changes surplus overflow files to zero-length by default. Or if the "truncate" query parameter is used, it actually deletes the surplus overflow files. This allows VACUUM to shrink the database again. (check-in: 5aefef04 user: drh tags: nx-devkit)
01:30		Call sqlite3_log() with an appropriate message if unable to find a unique master-journal filename. (check-in: e9177f7d user: drh tags: nx-devkit)
01:21		A better solution to being unable to find a unique master-journal filename: just delete an existing master-journal and reuse it. (check-in: 2685c2b9 user: drh tags: nx-devkit)
00:33		Make sure the antipenultimate character of master-journal filenames is a "9" in order to avoid collisions with other files in 8+3 filename mode. Also, limit the number of attempts at finding a unique master-journal filename. (check-in: 34a04836 user: drh tags: nx-devkit)
2011-12-15
17:44		Add stdio support to the quota VFS. (check-in: 322bd15f user: drh tags: trunk)
17:42		Use _commit() rather than FlushFileBuffers() as a substitute for fsync() on windows. Also cast for C++ and add support for SQLITE_FCNTL_VFSNAME. (Closed-Leaf check-in: e85cfe9a user: drh tags: quota-stdio)
17:00		When deleting a file with the multiplexor VFS, also delete any overflow files that exist. (check-in: 3af1feaa user: dan tags: nx-devkit)
13:29		Make sure the chunksize in test_multiplex does not cause the pending byte to fall near the end of a chunk. Adjust the chunksize upward as necessary to prevent this. (check-in: e05f8a29 user: drh tags: nx-devkit)
11:45		Fix some problems with dropped error codes in multiplexOpen(). (check-in: 2d50f781 user: dan tags: nx-devkit)
02:22		In the multiplexor, do not try to delete overflow files that do not exist. And assume all but the last overflow file is the size of the chunk size. (check-in: a822a80d user: drh tags: nx-devkit)
2011-12-14
18:33		Merge the nx-devkit changes into trunk. This includes the new SQLITE_FCNTL_VFSNAME file-control. (check-in: da118e02 user: drh tags: trunk)
18:28		Merge the VFSNAME file-control addition into the nx-devkit branch. (check-in: 08c1dc51 user: drh tags: nx-devkit)
17:53		Add a file-control that will discover the name of the bottom-level VFS and all the shims in between. (Closed-Leaf check-in: cdbfb553 user: drh tags: vfsname-filectrl)
01:38		Improvements to comments. No code changes. (check-in: 08bbbd8e user: drh tags: nx-devkit)
00:37		Treat a zero return value from the Win32 APIs MultiByteToWideChar and WideCharToMultiByte as an error condition. (check-in: c65e5a36 user: mistachkin tags: trunk)
00:04		Harden the utf8-to-mbcs converter in the quota module against failures. (check-in: 1cda511d user: drh tags: quota-stdio)
2011-12-13
23:26		Enhancements to test_quota.c: Remove the external dependency on sqlite3_win32_utf8_to_msbc(). Add an extra parameter to quota_fflush() that will also do an fsync (or the equivalent). (check-in: 92f4188f user: drh tags: quota-stdio)
19:03		Add a hard limit to the number of chunks a multiplexed database may consist of if ENABLE_8_3_NAMES is defined. (check-in: 43a12640 user: dan tags: nx-devkit)
18:22		Change the SQLITE_EXTRA_INIT routine to take a single argument which is a pointer to a string. Call SQLITE_EXTRA_INIT with a NULL argument.

15:02		Move the multiplexor changes in the experimental branch (check-ins [255d21499b] and [199f52bced]) into the nx-devkit branch. (check-in: eb95d2f7 user: drh tags: nx-devkit)
12:10		This branch merged with nx-devkit and from there into trunk. Was: In the multiplexor, instead of generating a unique file-name when SQLite opens a temp file, allow the underlying VFS to generate a different temp file for each chunk. Given the changes to the xFileSize method, it is no longer necessary for the different chunks of a temp file to use the same base name. (Closed-Leaf check-in: 199f52bc user: dan tags: experimental)
11:15		Change the way IO errors are handled in the xFileSize method of the multiplexor VFS. Add test file multiplex3.test. (check-in: 255d2149 user: dan tags: experimental)
04:08		When an sqlite3_auto_extension() function fails, report back its actual error code, not the generic SQLITE_ERROR. (check-in: ce55f250 user: drh tags: nx-devkit)
02:41		When the multiplexor FileSize procedure fails to open the file, assume that the file is zero bytes in size. (check-in: dc8118cd user: drh tags: nx-devkit)
01:34		Add a compile-time shutdown procedure to be called by sqlite3_shutdown() to undo the effects of the compile-time initialization procedure. (check-in: c2ed86f5 user: drh tags: nx-devkit)
2011-12-12
20:01		Backport a minimal set of changes needed to get 8+3 filenames and the multiplexor shim playing well together. (check-in: c4e2ce48 user: drh tags: nx-devkit)
19:48		Fix os_unix.c so that, unless 8.3 filenames are actually in use, journal and wal file permissions are assigned correctly even if SQLITE_ENABLE_8_3_NAMES is defined. (check-in: 169e1229 user: dan tags: trunk)
19:47		Make sure the quota logic is usable as C++. (check-in: f4534bd3 user: drh tags: quota-stdio)

18:21		Fix for the xFileSize method of test_multiplex.c when used on a file opened with the DELETEONCLOSE flag set. (check-in: 713071c4 user: dan tags: trunk)
16:51		Add magic comments to shell.c to make it easier for scripts to insert additional version information displays for custom builds. (check-in: 9b2691aa user: drh tags: trunk)
2011-12-11
22:44		In the multiplexor shim, when using 8+3 filenames, begin numbering journal overflow files with 101 instead of 001 to avoid name collisions with the main database file. (check-in: 05bf8a0b user: drh tags: trunk)
21:51		Update comments describing the flattening optimization in select.c. (check-in: dab4c137 user: drh tags: trunk)
02:30		Fix STAT3 so that it works with the new uninitialized register logic of the VDBE. Ticket [7bbfb7d4422ff] (check-in: d11a5798 user: drh tags: trunk)
02:29		Fix harmless compiler warnings. (check-in: 1e6a698a user: drh tags: trunk)
2011-12-10
23:18		Minor cleanups of the compound-subquery flattening logic. New test cases added for joins the compound subquery. (check-in: 5061d85f user: drh tags: trunk)
17:17		Allow UNION ALL compounds to be promoted up to replace a simple wrapper SELECT even if the compounds are joins. (check-in: 3d4b4f4f user: drh tags: trunk)
15:55		Import the experimental parse-tree explainer, with fixes, from the tree-explain branch. Disabled by default. Use SQLITE_ENABLE_TREE_EXPLAIN to turn it on. (check-in: bcbc7152 user: drh tags: trunk)

2011-12-09
18:06		Change the VDBE so that all registers are initialized to "Invalid" instead of NULL and report errors on any attempted read of an Invalid register. This will help prevent future bugs similar to [7bbfb7d442]. (check-in: 0064bab7 user: drh tags: trunk)
17:51		Remove an unnecessary condition. (Closed-Leaf check-in: d9ba023c user: drh tags: uninit-vdbe-mem)
17:38		Remove an unnecessary initialization of Vdbe.aOnceFlag. (check-in: 421714da user: drh tags: uninit-vdbe-mem)
17:27		Take out the OP_JumpOnce opcode. Revert compound SELECT to use OP_IfNot, which is the correct behavior. Mark trigger registers as initially invalid. (check-in: 6a9fb47d user: drh tags: uninit-vdbe-mem)
16:59		Previous check-in broke auto-increment. This check-in appears to fix it. (check-in: 28ffd39c user: drh tags: uninit-vdbe-mem)
16:21		Make no assumptions about the initial state of VDBE registers. (check-in: 521d72bd user: drh tags: uninit-vdbe-mem)

01:23		Improvements to the data-structure explain subsystem. Most queries now give a reasonably detailed graph of their parse tree. (check-in: 0aa7d3d2 user: drh tags: tree-explain)
2011-12-06
19:44		Begin adding the data-structure explaining subsystem. All is contained within (check-in: 79ae51c5 user: drh tags: tree-explain)
13:46		Add file tkt-3a77c9714e.test, containing tests to verify that the problem documented by ticket [3a77c9714e] has been fixed. (check-in: 162421da user: dan tags: trunk)
13:24		Do not reuse temp registers originally allocated to a subroutine within the main body of the program logic, since if the subroutine is called while the reused temp registers are in use, their values will get clobbered. Candidate fix for ticket [3a77c9714e63330] (check-in: 092d5331 user: drh tags: trunk)
00:47		Merge the winGetLastError fixes into trunk. (check-in: 5b03ba9d user: drh tags: trunk)

18:44		Add stdio-like I/O interfaces to the test_quota VFS. This is a prototype change for discussion and is mostly untested. This is an alternative to adding stdio-like I/O interfaces in the core. There is no guarantee that this code will make it into the trunk. If it does get to trunk, there could be many changes to the interface first. (check-in: bd3ce723 user: drh tags: quota-stdio)
02:32		Add a prototype implementation of stdio-like routines for accessing the VFS. This is intended as documentation. The code is untested. There is no guarantee that any of this will ever make it into trunk. Substantial revision is possible prior to reaching trunk, if it ever does. (Closed-Leaf check-in: 8936542b user: drh tags: vfs-stdio)
2011-11-29

18:08		Merge the PCACHE2 changes into trunk. (check-in: 457513f2 user: drh tags: trunk)
17:32		Change the multiplexor suffix from 2 to 3 digits. (Closed-Leaf check-in: 06e0cdaf user: drh tags: 3-digit-multiplex-suffix)
16:23		Remove code made obsolete by the changes to index processing that allow range search on the rowid. (check-in: a5418c7f user: drh tags: trunk)
15:41		Fix an invalid assert() statement added by [3b58f5f066]. (check-in: 888b09dd user: dan tags: trunk)
15:27		Where possible, take advantage of the rowid at the end of index records to optimize range constraints (<, >, <=, >=) on the rowid column. (check-in: 3b58f5f0 user: dan tags: trunk)
08:18		Update memsubsys1.test to account for the recently increased size of the MemPage structure in btreeInt.h. (check-in: 4fb3ca75 user: dan tags: trunk)
2011-11-14
12:34		Further work on mmap(). Still does not work right - autovacuum tests are the first to fail. (Closed-Leaf check-in: 638a39bb user: drh tags: mmap-experimental)
03:00		Forward port the 8-byte alignment fix from branch-3.7.9. (check-in: ebf6eb6e user: drh tags: trunk)

01:55		Begin making experimental changes to use mmap() for reading content from a database. The code compiles, but crashes on the test suite. (check-in: 09be42d5 user: drh tags: mmap-experimental)
2011-11-13
21:44		Add a version number to the sqlite3_pcache_methods2 object. Other PCACHE2 documentation improvements. (Closed-Leaf check-in: 9f839ac0 user: drh tags: experimental-pcache)
2011-11-12
23:10		Attempt to modify btree.c so that it assumes that calls to sqlite3PagerWrite() will reallocate the page buffer. As there is not good way to test this assumption yet, probably a few spots were missed. (check-in: ceee03c7 user: drh tags: experimental-pcache)
16:46		Remove a couple of incorrect assert statements so that the test suite will run with -DSQLITE_DEFAULT_CACHE_SIZE=0. (check-in: 87614b62 user: drh tags: trunk)
15:41		Merge the windows xSyscall enhancements into trunk. (check-in: c1fab9ac user: drh tags: trunk)
03:17		Make sure to flag benign malloc failures in the Windows VFS as such. Expand use of the DO_OS_MALLOC_TEST to cover the VFS functions that can now return an out of memory error.

2011-11-10
21:45		Expand passing of a last error argument to the getLastErrorMsg function. Also, remove unused SQLITE_W32_THREADS define. (check-in: 8f287979 user: mistachkin tags: trunk)
20:21		In winAccess, save the Win32 last error value prior to invoking user logging callback. Also, explicitly pass the Win32 last error value to winLogError in order to keep it accurate. Fixes a problem reported on the mailing list. (check-in: 32ab3657 user: mistachkin tags: trunk)
02:39		Follow-on to the previous check-in to prevent a division by zero if the lookahead slot size is something goofy like 6 on a 32-bit machine. (check-in: 6bda711f user: drh tags: experimental-pcache)

2011-11-09
18:07		Omit an unnecessary Sleep() call in windows pending-lock retry logic. Enhance the comment on that logic to discourage people from copying it into other VFSes. (check-in: 0c951a97 user: drh tags: trunk)
17:01		When compiling with MSVC, use the _msize function. (check-in: 797a1479 user: mistachkin tags: experimental-pcache)
16:12		Minor changes needed to restore full branch test coverage. (check-in: bc10a753 user: drh tags: experimental-pcache)
14:23		A negative value N for the cache_size pragma adjusts the number of cache pages to use approximately N kibibytes of memory. (check-in: b3faa680 user: drh tags: experimental-pcache)
01:53		For the mem1.c system malloc implementation, use the malloc_usable_size() function if the HAVE_MALLOC_USABLE_SIZE macro is defined. Update autoconf to look for that function when configuring. (check-in: 2e8ab3ce user: drh tags: experimental-pcache)
00:06		Update the API documentation for the new pcache2 interface. Change the order of parameters on the xCreate method of pcache2. (check-in: 4da70956 user: drh tags: experimental-pcache)
2011-11-08

2011-11-07
18:16		Make the unix VFS tolerant of read() calls that return less than the requested number of bytes. (check-in: a210695a user: drh tags: trunk)
17:54		Amplify the restriction on commit-hooks that they cannot recursively run SQL on the same database connection. (check-in: 4fe5b731 user: drh tags: trunk)
16:46		Add a makefile target for tclsqlite3.c to Makefile.in. (check-in: f521b6b7 user: drh tags: trunk)
13:05		Change the default file format from 1 to 4. This means that, unless PRAGMA legacy_file_format=ON is used first, new databases will not be readable by versions prior to 3.3.0 (2006-01-10). (check-in: a35f52b1 user: drh tags: trunk)
2011-11-06
05:06		Move function sqlite3PagerClearCache() out of the "ifndef SQLITE_OMIT_WAL" block and into an "ifndef SQLITE_OMIT_VACUUM" block. (check-in: 5dbfaed8 user: dan tags: trunk)
2011-11-04
14:36		Update the xfer optimization code so that the xfer optimization can be used with INTEGER PRIMARY KEY ON CONFLICT ... as long as the destination table is initially empty. Improvements to the comments on the xfer optimization. New test cases added. (check-in: e3f368cd user: drh tags: trunk)

02:24		Use mkdir() and rmdir() rather than open() and unlink() to create the lock files with the unix-dotlock VFS. The change is backwards compatible and, we are told, works better on some network filesystems. (check-in: e2f08426 user: drh tags: trunk)
00:35		Enhance the shell so that the ".schema" command works with case insensitive LIKE patterns even with PRAGMA cache_sensitive_like=ON. (check-in: b06bf3b3 user: drh tags: trunk)
00:23		Make sure the INSERT INTO ... SELECT statement works correctly even when the destination table contains an INTEGER PRIMARY KEY ON CONFLICT... column. Ticket [676bc02b87176125]. (check-in: 6f9898db user: drh tags: trunk)
2011-11-01

21:49		Add assert() statements and eliminate needless variable assignments in order to get the clang scan-build utility to report zero problems against the SQLite core. Clang's static analysis did find one real problem - but it was in the command-line shell, not in the SQLite core. (check-in: 60fee957 user: drh tags: trunk)
2011-10-13
18:08		Change the makefile to delete both plain and ".exe" variants of build tools. Ticket [92bd6eaf04e117] (check-in: 19536a38 user: drh tags: trunk)
18:00		Simplifications to the upper() and lower() SQL functions.

00:17		The build works again with -DSQLITE_OMIT_MERGE_SORT. The merge-sorter now avoids spilling to disk (letting the in-memory linked list grow without bound) if PRAGMA temp_store=3. (check-in: 68e26c44 user: drh tags: merge-sort)
2011-09-02

23:57		Avoid using uninitialized variables after failures in the merge sort code. (check-in: 2869ed28 user: drh tags: trunk)
21:01		Formerly, we enabled fdatasync() on linux only. But now we learn that fdatasync() is not supported on Android. So we disable fdatasync() on Linux too. It can be reenabled at compile-time for those who really need it. (check-in: 70b5b309 user: drh tags: trunk)
20:47		Add the SQLITE_MAX_SCHEMA_RETRY compile-time option to the set of options understood by "PRAGMA compile_options;" and by the "sqlite_compileoption_used()" function. (check-in: 1b124af4 user: drh tags: trunk)
19:40		The server1.test script should only run if mutexes are functional. Fix to the #ifdef change of check-in [9e6a4c1473]. (check-in: 64898485 user: drh tags: trunk)
18:35		Always include the unixShm.id field, even when not debugging. (check-in: 07803476 user: drh tags: trunk)
18:04		Only create the sqlite3OSTrace global variable if compiling with SQLITE_TEST. (check-in: 9e6a4c14 user: drh tags: trunk)
17:46		Backslash escaping is not working right in tostr.awk on the latest ubuntu. The easiest fix is to simply not use any backslashes in the spaceanal.tcl script. (check-in: df550066 user: drh tags: trunk)
13:27		Add checks to make sure cells in corrupt database files do not overflow a page when doing autovacuum. Problem detected by valgrind. (check-in: d0b347b4 user: drh tags: trunk)
2011-08-30
19:52		Enable the thread test logic to work with the SQLITE_HAS_CODEC compile-time option. (check-in: 20ddfb47 user: drh tags: trunk)
01:29		Change the build process so that it does not require the unix "sort" command. This avoids confusion between ms-sort and mingw-sort on windows systems. (check-in: f1bd5bba user: drh tags: trunk)
01:23		Make sure SQLITE_FCNTL_SIZE_HINT a no-op if the chunk size is not greater than zero. (check-in: 88b763e8 user: mistachkin tags: trunk)
00:58		Fix a total unimportant file descriptor leak in lemon. This is to silence warning messages. (check-in: e95cf2c5 user: drh tags: trunk)

00:34		Create a new pager type, PAGER_SORTER, for use in the external merge sort. Such pagers are always held in memory but do report when they are under memory pressure by calling pagerStress. (check-in: c71d7320 user: drh tags: trunk)
2011-08-25
20:18		Reorder some of the branches in backup.c in order to make the code easier to test. (check-in: 2c443d47 user: drh tags: trunk)
19:28		Replace an assert() that a condition may not occur in backup.c with code to handle that condition, which can occur. (check-in: 472c74b3 user: dan tags: trunk)
18:54		Fix harmless compiler warnings in test code. No changes to the core. (check-in: 16f83fec user: drh tags: trunk)

2011-08-23
23:41		Simplifications to the SQLITE_PAGECACHE_BLOCKALLOC logic. Reduce the number of difficult-to-reach branches. (check-in: d5d835fe user: drh tags: trunk)
20:11		If the application-defined openDirectory() function returns SQLITE_CANTOPEN, then silently ignore the error. This allows the chromium sandbox to disallow opening of directories without causing errors. (check-in: 880b5115 user: drh tags: trunk)
19:46		Change the way the "crash" VFS (test6.c) handles SQLITE_FCNTL_SIZE_HINT. (check-in: 40dd8a60 user: dan tags: trunk)
18:06		Merge latest trunk changes into the apple-osx branch. (check-in: c5f7977b user: dan tags: apple-osx)
16:41		Have the "crash" VFS used by the tcl tests (test6.c) handle SQLITE_FCNTL_SIZE_HINT internally, instead of passing it directly through to the underlying VFS. This is important if the crash VFS is simulating non-default device characteristics such as SQLITE_DEVCAP_SEQUENTIAL or ATOMIC. (check-in: fac8bc8f user: dan tags: trunk)
13:27		Ifdef out routines in pcache1.c that are used only when SQLITE_PAGECACHE_BLOCKALLOC is defined. (check-in: 0da292da user: drh tags: trunk)

11:47		When copying a rollback mode database over a WAL database using the backup API, leave the destination database in WAL mode (instead of switching it to rollback mode). Fix for [af95b8c609]. (check-in: 35e6ac18 user: dan tags: trunk)
05:10		Change to test instrumentation of os_unix.c: Regard IO errors that occur within SQLITE_FCNTL_SIZE_HINT requests as benign. (This check-in was intended for trunk and went onto the branch accidentally.) (Closed-Leaf check-in: ca47da2a user: dan tags: pager-blockalloc)
00:01		Remove a branch that is always true. (check-in: a6568192 user: drh tags: trunk)

09:54		Fix for [b1d3a2e531]. (check-in: 3f3acee4 user: dan tags: trunk)
2011-08-19
18:15		Experimental change: If SQLITE_PAGECACHE_BLOCKALLOC is defined, instead of allocating pages one at a time, allocate blocks of between 15 and 63 pages in a single allocation. (check-in: 63597097 user: dan tags: pager-blockalloc)
14:54		When retrying a write() after an EINTR error on unix, be sure to also rerun the previous lseek(). Ticket [e59bdf6116036a] (check-in: 21452f3a user: drh tags: trunk)
2011-08-18

00:40		Use OP_Sort rather than OP_Rewind in order to sort the content of a new index on the CREATE INDEX statement. Add an ALWAYS() to the merge sort logic to document an unreachable branch. (check-in: f01766f4 user: drh tags: trunk)
2011-08-16
17:06		Fix a few harmless compiler warnings. Add SQLITE_ENABLE_STAT3 to the standard compiler warning script. (check-in: 3d68f9af user: drh tags: stat3-enhancement)
02:07		Allow the sqlite3VdbeJumpHere() routine to accept a negative or zero address if a prior memory allocation error has occurred. The new sqlite_stat3 logic needs this. (check-in: 9650d796 user: drh tags: stat3-enhancement)
01:15		Add the analyze8.test test module for sqlite_stat3. (check-in: 2c83ac89 user: drh tags: stat3-enhancement)

15:27		New makefile target "sqlite3-debug.c" builds an amalgamation that include appropriate "#line" macros relating the code back to the original source files. (check-in: 26f2da24 user: drh tags: trunk)
14:41		When opening a temporary file to use in a merge-sort, pass SQLITE_OPEN_TEMP_JOURNAL instead of SQLITE_OPEN_TEMP_DB. This is a better fit, as merge-sort files are written and read sequentially like journal files. (check-in: bd04756b user: dan tags: trunk)
12:58		Update some test cases to work with sqlite_stat3 instead of sqlite_stat2. (check-in: 2504bcfb user: drh tags: stat3-enhancement)
12:02		Fix a couple of typos in comments in analyze.c. (check-in: ae31dc67 user: dan tags: stat3-enhancement)

15:02		Add the SQLITE_OMIT_MERGE_SORT pre-processor directive. To omit the code in vdbesort.c. (check-in: 4ced2394 user: dan tags: experimental)
11:59		Add tests to improve coverage of vdbesort.c. (check-in: 87a15917 user: dan tags: experimental)
01:51		Begin a branch that experimentally replaces sqlite_stat2 with a new table called sqlite_stat3 that will hopefully facilitate better query planning decisions. (check-in: 52e1d7e8 user: drh tags: stat3-enhancement)
2011-08-10
01:52		Make the openDirectory routine in os_unix.c overrideable so that it can be turned into a harmless no-op for the chromium sandbox. (check-in: 6b236069 user: drh tags: trunk)
2011-08-09
18:14		Add command-line utilities "offsets.c" and "extract.c" for use in low-level analyzsis of database files. (check-in: dfa22ed4 user: drh tags: trunk)
2011-08-08
23:48		In os_unix.c, do not open the directory containing the database file when the database file is opened. Instead, wait until time to fsync() the directory. And do not report an error if the open fails, since some systems (Ex: AIX and a chromium sandbox) are unable to open and fsync directories. (check-in: 713b1b7d user: drh tags: trunk)
23:18		Allow the unlink() system call to be overridden in os_unix.c. (check-in: 8d1b5c3a user: drh tags: trunk)
19:26		Remove redundant parameter from vdbeSorterInitMerge() in vdbesort.c. (check-in: eec8c0df user: dan tags: experimental)
17:18		Add code to actually use the sqlite_stat2.cnt field in the query planner. This changes some plans resulting in a few failures in analyze5.test. (Closed-Leaf check-in: d1248165 user: drh tags: query-planner-tweaks)
16:44		Add fault-injection and other tests (and fixes) to improve coverage of vdbesort.c. (check-in: 0e6defa6 user: dan tags: experimental)
2011-08-07
01:31		Remove relevant elements from the sqlite_stat2 table when doing a DROP INDEX or DROP TABLE. (check-in: 3c8f97ae user: drh tags: trunk)

2011-06-09
17:53		Fix a line in pcache1.c where a global data structure is accessed without using the GLOBAL() macro. This causes a subtle malfunction on test systems that use SQLITE_OMIT_WSD. (check-in: b11b2e1f user: dan tags: trunk)
10:48		Fix problems to do with using both OR and NEAR operators in a single expression. (check-in: 4e8dd19e user: dan tags: fts3-prefix-search)

20:04		Allow the "order=DESC" and "order=ASC" parameters in FTS4 "CREATE VIRTUAL TABLE" statements. Tables created with "order=DESC" store all doclists in descending order, which allows optimizations normally applied to "ORDER BY docid ASC" queries to be used with "ORDER BY docid DESC" queries instead. (check-in: f6a0193f user: dan tags: fts3-prefix-search)
01:43		Performance improvement to the btree search routine. (check-in: 65db822f user: drh tags: trunk)

13:04		Merge the read-only shared memory branch into trunk. After this merge, an unprivileged process can open WAL-mode databases owned by another user as long as a database connection with write permission exists on the database file and if the readonly_shm=1 URI query parameter is supplied. (check-in: 19084a66 user: drh tags: trunk)
2011-06-01
20:13		Make use of the sqlite3GetBoolean() interface for more robust processing of the readonly_shm query parameter inside of unixShmMap(). (Closed-Leaf check-in: 1f930d7e user: drh tags: wal-readonly)

11:26		Toward version 3.7.5.1. This check-in updates the version number and also patches the pager so that it never spills cache while in WAL mode. The latter patch fixes ticket [2d1a5c67dfc23] and also prevents excessive WAL file sizes if the pager cache starts thrashing. A few test cases fail. (Leaf check-in: 2e5a912a user: drh tags: branch-3.7.5)
2011-05-31

15:36		Do not invoke the xRollbackTo or xRelease methods of a virtual table without having first invoked an appropriate xSavepoint method. Add assert() statements to FTS3/4 to verify that this is happening in all cases. (check-in: 651ef242 user: drh tags: trunk)
00:35		Make sure the savepoint index is correct one calls to sqlite3VtabSavepoint with SAVEPOINT_BEGIN. (check-in: a9d09566 user: drh tags: trunk)

01:50		Fix the URI test script so that it works even if there is a subdirectory named "test". (check-in: 2018d4e1 user: drh tags: trunk)
01:49		Mark an unreachable branch in the recent WAL problem as unreachable. (check-in: 3e8a29ff user: drh tags: trunk)
2011-05-19

2011-05-13
18:51		Make arrangements so that virtual table inserts into shadow tables do not modify the sqlite3_last_insert_rowid() return. Document that this is how sqlite3_last_insert_rowid() works. (check-in: e569f18b user: drh tags: trunk)
17:11		Rather than document goofy behavior, it seems better to make the behavior less goofy. (Was: Updates to the sqlite3_last_insert_rowid() documentation - to make it clear that the function does not work for virtual tables.) (Closed-Leaf check-in: f88dfac3 user: drh tags: mistake)
17:11		Also add fts3_term.c to main.mk. (check-in: 966f2d2c user: drh tags: trunk)

2011-05-11
20:54		Improvements to documentation hyperlinks. Change the value of SQLITE_OPEN_URI to an unreserved value. (check-in: 851ab75d user: drh tags: trunk)

2011-05-10
18:39		Have flags passed to sqlite3_open_v2() apply to the main and any attached databases. And change things so that any "mode=xxx" or "cache=xxx" options specified as part of a URI for the main database do not also apply to attached databases. (check-in: 3e490915 user: dan tags: trunk)
17:43		Update URI test cases to account for the new error message format. (check-in: 5bde5680 user: dan tags: trunk)

18:55		Merge the uri branch with the trunk. (check-in: 88df33c4 user: dan tags: trunk)
18:53		Remove some unnecessary modifications from the uri branch. Add a test to show that ATTACH only interprets its argument as a URI if the connection was opened with SQLITE_OPEN_URI (or URI interpretation is globally enabled). (Closed-Leaf check-in: aa90b943 user: dan tags: uri)
18:34		Update comments and documentation associated with new URI parsing code. Add test file e_uri.test, containing tests mapped to documentation regarding URI filenames. (check-in: 92751788 user: dan tags: uri)

22:57		Backport check-ins [0900e35348f4b9bf3] and [4fead8e714c7e50] to the 3.7.2 branch. These check-ins provide hints to the btree layer for when it is possible to use a hash table rather than a btree to implement an index. The SQLite BTree layer does not use these hints, but alternative btree layers might. (check-in: 7155e6f3 user: drh tags: branch-3.7.2)
2011-04-28
18:46		Have r-tree virtual tables support on-conflict clauses. (check-in: 822ab52f user: dan tags: vtab-conflict)

15:54		Have the ATTACH command do URI interpretation in the same way as sqlite3_open() and sqlite3_open_v2() do. (check-in: 68240e75 user: dan tags: uri)
10:12		Fix parsing of %00 in uri handling code. (check-in: 44f0874a user: dan tags: uri)
2011-04-22

17:14		Change the prototype for the open() system call to agree with Posix. Though a faulty function prototype in a pointer cast is a seemingly innocuous error, the correct prototype is necessary for pthreads to work correctly on NetBSD. (check-in: 986f2f25 user: drh tags: branch-3.7.6)
17:09		Change the prototype for the open() system call to agree with Posix. Though a faulty function prototype in a pointer cast is a seemingly innocuous error, the correct prototype is necessary for pthreads to work correctly on NetBSD. (check-in: 3e135748 user: drh tags: trunk)
00:55		Adjust some test cases in triggerC.test to handle non-default SQLITE_MAX_TRIGGER_DEPTH settings. (check-in: 9d6c6129 user: shaneh tags: trunk)

02:09		Do not do a backup if the number of reserved bytes in the source and destination do not match. Try to make the match, but if unable fail. (check-in: 0ca8a233 user: drh tags: trunk)
2011-04-08

23:04		Make sure the left-hand side of the IS NOT NULL operator is a simple column and not a general expression before applying the IS NOT NULL optimization. This is a backport of check-in [543f75a6abe3]. (check-in: e8177e01 user: drh tags: branch-3.7.2)
21:35		Always make sure the left-hand side of the IS NOT NULL operator is a simple column, not a general expression, before applying the IS NOT NULL query optimization. (check-in: 543f75a6 user: drh tags: trunk)

22:33		Merge in the latest changes from the trunk. (check-in: 435b57dc user: drh tags: sessions)
22:05		Fix a performance regression: Keep two btree masks in each prepared statement; one for btrees used and another for btrees that require locks. Only try to lock the btrees identified by the second mask. (check-in: 614de91a user: drh tags: trunk)
19:15		Fix a benign inaccuracy in the os_unix.c SQLITE_FCNTL_SIZE_HINT code. (check-in: 61a6ccbe user: dan tags: trunk)
17:54		Changes to support building with various SQLITE_OMIT_XXX options defined. (check-in: 2039ed95 user: dan tags: trunk)

22:10		Merge the latest trunk changes into the apple-osx branch. (check-in: c77a767c user: drh tags: apple-osx)
22:08		Suppress many harmless compiler warnings, mostly signed/unsigned comparisons within asserts or unused parameters in extensions. (check-in: 3eeb0ff7 user: drh tags: trunk)
19:27		Simplifications to the sqlite3BtreeEnterAll() and LeaveAll() routines. Just have them call BtreeEnter and BtreeLeave() repeatedly rather than trying to be clever. (check-in: 51039b35 user: drh tags: trunk)
19:26		Simplifications to the sqlite3ResetInternalSchema() logic to eliminate unreachable branches. (check-in: a4c3ac98 user: drh tags: trunk)
18:34		Remove dead code from the OP_JournalMode opcode in the VDBE. This code seems to have been useless since [f88c6367d2] on 2010-08-07. (check-in: a89f24e2 user: drh tags: trunk)
17:31		Remove the mutex counter and the logic that attempts to verify that btree mutexes are held continuously. We are not making that assumption at this time. (check-in: 242ce7cf user: drh tags: trunk)
16:09		When committing a WAL transaction, do not write any pages to the WAL file with page numbers greater than the size of the database image in pages. (check-in: 311d0b61 user: dan tags: trunk)

12:25		Fix the P4_TRANSIENT constant so that it works correct - so that it really makes a copy of the string for the P4 argument. Use P4_TRANSIENT wherever appropriate. Change P4_STATICs of schema names to P4_TRANSIENT. (check-in: bf664b20 user: drh tags: trunk)
11:26		Improved comment on the sqlite3SrcListLookup function. (check-in: bcbc9ff5 user: drh tags: trunk)

14:05		Merge test_syscall.c fix from the trunk. (check-in: 1e1a23cc user: dan tags: schema-parse-refactor)
14:03		Have test_syscall.c include "sqliteInt.h". Otherwise the SQLITE_OS_UNIX symbol may not be defined correctly. (check-in: fda8fadd user: dan tags: trunk)
13:40		Rename sqlite3SchemaFree() to sqlite3SchemaClear() to more accurately reflect its function. (check-in: 71d74400 user: drh tags: schema-parse-refactor)

12:29		Move the expired-statement test for OP_Function until after all memory has been freed. The test is still commented out, however. (check-in: 425e3edb user: drh tags: trunk)
07:05		Changes to oserror.test and syscall.test so that they work with the in-memory journal permutation test. (check-in: 4e996f36 user: dan tags: trunk)
03:27		Suppress unused parameter warnings in sqlite3VdbeEnter() and related routines. (check-in: f8e98ab3 user: drh tags: trunk)
00:14		Remove the BtreeMutexArray object - use the Vdbe.btreeMask field to accomplish the same result. Add a generation counter to btree mutexes in order to assert that mutexes are never temporarily dropped over a range of instructions in order to do deadlock avoidance in some subroutine. Lock all btrees in any Vdbe program that uses OP_ParseSchema. (check-in: d81708f7 user: drh tags: trunk)
2011-04-03
18:19		Make sure that the constant 1 is cast to yDbType before shifting to create an attached database mask. This check-in is a follow-up and fix to the [7aaf8772274422] change that increases the maximum number of attached databases from 30 to 62. (check-in: e2a09ea7 user: drh tags: trunk)

17:00		Avoid returning SQLITE_NOTFOUND when the unix xSetSystemCall interface is invoked with NULL passed as the second argument, even if all the default system calls are already installed. (check-in: 3b91eaaa user: dan tags: trunk)
16:50		When resetting any non-TEMP schema, also reset the TEMP schema since it might be holding references to the non-TEMP schema that just got reset. (check-in: 211d5dde user: drh tags: schema-parse-refactor)
16:28		Begin a series of changes designed to reduce the scope and frequency of invalidating schemas. Design goals are that the internal schema should never be deleted out from under a prepared statement that is running and that all prepared statements should be expired if the schema is invalidated. At the same time, minimize the number of schema invalidations. This change merely revises the sqlite3ResetInternalSchema() function to use -1 as the wildcard for "all" rather than 0, so that we can reset the main schema independently of all the others. (check-in: 6a8ad6e3 user: drh tags: schema-parse-refactor)
09:44		Fix a race condition in OP_ParseSchema. (check-in: 71a799b0 user: dan tags: trunk)

18:39		Merge the multiplexer enhancements back into the trunk. (check-in: 2c125710 user: drh tags: trunk)
18:12		Add a script that will break the amalgamation source file up into 4 or 5 smaller source files, each 32K lines or fewer, and a single "sqlite3-all.c" source file that #includes the others. (check-in: 5d34e64d user: drh tags: trunk)
17:53		Change analyze7.test so that it works without SQLITE_ENABLE_STAT2 defined. (check-in: 9415201c user: dan tags: trunk)
16:50		When simulating an error in the close() system call, close the file descriptor anyway. Otherwise long running tests leak too many file-descriptors and crash. (check-in: 81ddbf43 user: dan tags: trunk)
15:43		Merge latest trunk changes. (check-in: d184cf00 user: dan tags: sessions)
15:30		If the sessions module is being built as part of the amalgamation, do not try to include sqliteInt.h and vdbeInt.h. (check-in: f87bfe6e user: dan tags: sessions)
15:15		Ensure that it is not possible to add a column to a system table using ALTER TABLE. (check-in: d9707ef8 user: dan tags: trunk)
14:26		Merge the ANALYZE-index enhancement into trunk. (check-in: 7e237aea user: drh tags: trunk)
14:22		Removed dependency on sqliteInt.h so that multiplex VFS shim can be compiled as loadable module. (Closed-Leaf check-in: 718f1ad7 user: shaneh tags: multiplex-enhancements)
14:04		Test cases for ANALYZE-index. (Closed-Leaf check-in: 365896cb user: drh tags: analyze-idx)
13:29		Move a variable declaration inside an #ifdef to avoid a compiler warning. (check-in: 7a6d05df user: drh tags: trunk)

2011-03-31
18:36		Provide hints to the btree layer Next and Previous primitives to let them know if they can be no-ops if the underlying index is unique. (check-in: a5aae174 user: drh tags: branch-3.7.2)
15:11		Enable/disable support. (check-in: b3c6d9aa user: shaneh tags: multiplex-enhancements)
13:14		Add tests and fixes for SELECT multiplex_control(op, val); (check-in: fee9734c user: shaneh tags: multiplex-enhancements)
05:31		Additional test cases; Round chunk size up to a multiple of max page size; (check-in: 36e364a3 user: shaneh tags: multiplex-enhancements)
02:03		Change the ANALYZE command so that it will accept an index name as its argument and only reanalyze that one index. A quick smoke-test works. Need to study the implications to the query planner and test corner cases. (check-in: c8f9edd9 user: drh tags: analyze-idx)
2011-03-30
21:04		Add the SQLITE_ENABLE_PREUPDATE_HOOK compile-time option. (check-in: 66345214 user: drh tags: sessions)

02:03		Merge in all the latest changes from trunk. (check-in: b11d941e user: drh tags: sessions)
01:43		Move to an O(NlogN) algorithm for the priority queue. An insertion sort was way too slow. (check-in: 7958cbba user: drh tags: word-fuzzer)
2011-03-29
23:41		Add support for rowid. (check-in: 2cf4158f user: drh tags: word-fuzzer)

15:40		Fix a problem whereby following an IO error in CommitPhaseTwo() of a multi-file transaction the b-tree layer could be left in TRANS_WRITE state, causing problems later on. (check-in: dbe569a0 user: dan tags: trunk)
15:00		If the keyword "unordered" appears at the end of the SQLITE_STAT1.STAT column for an index, then use that index for equality lookups only, never for range queries or sorting. (Closed-Leaf check-in: 3b964155 user: drh tags: unordered-index-hack)
14:08		Further improvements to the fuzzer. It still is not quite working. Pausing to work on other things.... (check-in: 5f2f2fce user: drh tags: word-fuzzer)
10:04		Fix a problem in the unix VFS implementation of xNextSystemCall(). Also some typos that prevent compilation when HAVE_POSIX_FALLOCATE is defined. (check-in: bc6cce81 user: dan tags: trunk)
05:06		In-progress changes - do not use; Removed prefix support; Added file control interface to enable/disable and adjust chunk size; added app-def function for same; (check-in: bc02d0c1 user: shaneh tags: multiplex-enhancements)
01:47		Fix the documentation for the sqlite3_column_*_name() functions to describe that the information can be invalidated when a prepared statement is reprepared by the first invocation of an sqlite3_step() for a particular execution cycle. (check-in: 7270f80a user: drh tags: trunk)
2011-03-28
19:10		Add test infrastructure (and some tests) to inject faults into os_unix.c using the new xSetSystemCall interface. (check-in: 0e1d20df user: dan tags: trunk)
2011-03-26
19:04		Added most of the logic. Simple test runs without segfaulting but does not give the correct answer. (check-in: fb4c31ea user: drh tags: word-fuzzer)
15:05		Skeleton code for the word-fuzzer virtual table. (check-in: ea3a4ee1 user: drh tags: word-fuzzer)

2011-03-24
17:43		Minor change to sqlite3Utf8Read() to make consistent with READ_UTF8() usage and avoid implementation defined usages of <<. Added some additional UTF-8 test cases. (check-in: 7173b392 user: shaneh tags: trunk)
17:37		Fix problem with tableapi.test on Windows. (check-in: 69fe0c87 user: shaneh tags: trunk)

2011-03-23
22:54		Fix a signed/unsigned comparison compiler warning. (check-in: c81da6f9 user: drh tags: trunk)

16:45		Update the implementation of ".testctrl" in the command-line shell to use a look-up table rather than a long sequence of if-elses. Shorten source code lines of shell.c to 80 characters or less. (check-in: 54bacb95 user: drh tags: trunk)
01:58		Comment enhancement to better explain the logic in the "x IS NULL" optimization. (check-in: 869f8947 user: drh tags: trunk)
01:53		Backport the "x IS NULL" query planner enhancement of [2353176811f] to the 3.7.2 branch. (check-in: 68daf20d user: drh tags: branch-3.7.2)
01:34		Enhances to the query planner such that "x IS NULL" constraints take the STAT2 statistics into account, just like "x=VALUE" constraints. (check-in: 23531768 user: drh tags: trunk)
2011-03-16
19:59		Add the sqlite3_preupdate_new() API, for retrieving the new.* values from within a pre-update callback. (check-in: 526545c4 user: dan tags: sessions)

2011-03-12
18:10		In the "unix-excl" VFS, use the heap for shared memory, since only a single process is able to read or write the database. (Closed-Leaf check-in: a05a6d40 user: drh tags: unix-excl)
17:22		Fix some issues with UPDATE changes in the session module. (check-in: 57862efe user: dan tags: sessions)
17:02		Add the new optional "unix-excl" VFS. This VFS grabs an exclusive lock on the database preventing other processes from accessing it, but continues to allow other database connections from the same process. (check-in: 00051c32 user: drh tags: unix-excl)
05:55		Backport the SQLITE_OMIT_UNIQUE_ENFORCEMENT change from check-in [b86999436e] on the trunk. (check-in: 668b91db user: shaneh tags: branch-3.7.2)

16:39		Merge the syscall-override changes into trunk. (check-in: 36d79e6f user: drh tags: trunk)
14:05		Unix errno integer can vary from one system to the next. So do not depend on specific errno values in test cases. (check-in: ddb747d3 user: drh tags: trunk)
13:06		Fix two compiler warnings. No functional code changes. (check-in: c829868a user: drh tags: trunk)
02:38		Fix additional cases of possible signed integer overflow, especially with regard to negation. (check-in: 2d5800bd user: drh tags: trunk)

21:54		Another minor simplification brought to light by clang. (check-in: 3bfbf026 user: drh tags: trunk)
21:28		Remove dead code identified by the clang static analyzer. (check-in: 01a79d5a user: drh tags: trunk)
2011-03-05
21:41		Simplifications to the overflow-free multiplier. Also remove some commented-out code that was left in that subroutine by mistake on the previous check-in. (check-in: 55fc25fd user: drh tags: trunk)
20:59		Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. (check-in: abf21394 user: drh tags: trunk)
13:54		Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. (check-in: 04abab71 user: drh tags: trunk)
2011-03-04
15:43		Handle EINTR errors from open(). (Closed-Leaf check-in: a7d176b2 user: drh tags: syscall-override)

15:09		Proof-of-concept prototype for the proposed xSetSystemCall extension method on the VFS. (check-in: 92b5a76a user: drh tags: syscall-override)
02:08		Log all error from close() in os_unix.c to sqlite3_log() but do not attempt to report errors back up to the application. Update the unix error logging to put the most important information earlier in the message. (check-in: 7b6e30e6 user: drh tags: trunk)
2011-03-01
18:42		Add the experimental sqlite3_preupdate_hook() API. (check-in: 6145d7b8 user: dan tags: sessions)
2011-02-25
03:25		Comment out some code in os_unix.c that only runs on MacOSX with SQLITE_ENABLE_LOCKING_STYLE. (check-in: 4e50b036 user: drh tags: trunk)
2011-02-24
21:10		Fix a typo in a comment. No changes to code. (check-in: af475618 user: drh tags: trunk)
2011-02-23
22:39		Reserve a range of bits in the SQLITE_OPEN_xxxx bit vector for future expansion. (check-in: 9b904654 user: drh tags: trunk)
14:33		Automatically retry system calls that fail with EINTR. This is a backport of the changes from [b9d29ea385bafc] and [af9ba2a6d2c379]. (Leaf check-in: 8609a15d user: drh tags: branch-3.7.4)

13:53		The robust_flock() fix that accidently included some unrelated, though harmless changes. I should follow my own checklist! (Closed-Leaf check-in: e701efbd user: drh tags: mistake)
13:33		Retry selected system calls on unix when they fail with EINTR. (check-in: b9d29ea3 user: drh tags: trunk)
2011-02-22
03:34		When a stale schema-cookie is seen, expire only the one statement that encountered the bad cookie, not every statement on the database connection. Ticket [b72787b1a7cea1f] (check-in: 1bca0a7e user: drh tags: trunk)
2011-02-21
17:49		Fix a problem with "EXPLAIN QUERY PLAN SELECT count(*) FROM tbl". (check-in: 9f9f3288 user: dan tags: trunk)

03:40		Do not report the database corruption if the the db size header field is greater than the file size on disk unless the two change-counter header fields are identical. Fix for ticket [89b8c9ac54]. Backport by cherrypick of [00c4596f0b270]. (check-in: e2616004 user: drh tags: branch-3.7.4)
03:32		Make sure the change-counter and SQLite-version fields of the header are set correctly even after vacuuming. This is a backport of changes [0be92a7576] and [04fa1e1690] to address ticket [5d863f876ee]. (check-in: 442be135 user: drh tags: branch-3.7.4)
03:27		Do not raise an SQLITE_CORRUPT error in Recoverymode if the database size in the header is larger than the physical file size. This is a cherrypick of checkin [114640d920e16c8] (check-in: 7701b077 user: drh tags: branch-3.7.4)
03:22		Backport the sqlite3.h generator fix so that it works with newer versions of Fossil. See [3513bf6ee090d9b] for the original. (check-in: 29597a71 user: drh tags: branch-3.7.4)
03:20		Backport the changes of checkin [cf86affcb7d308949] ("Make wal_checkpoint a no-op if a prior checkpoint has already copied all WAL content into the database.") to the 3.7.4 release. (check-in: e6e540ab user: drh tags: branch-3.7.4)
03:11		Backport the SQLITE_PROTOCOL fix and the extra defensive measure to version 3.7.4. (check-in: bcc22c4b user: drh tags: branch-3.7.4)
2011-02-19
23:18		An SQLITE_PROTOCOL error counts as a locking error for verification purposes. (check-in: e87d499a user: drh tags: trunk)
17:02		Change a testcase() added by the previous checkin into an assert(). (check-in: 6f3dad32 user: drh tags: trunk)
16:51		Add testcase macros to verify that all return values from walTryBeginRead() are tested. (check-in: 262b6fca user: drh tags: trunk)
15:22		Changes to make WAL more robust against SQLITE_PROTOCOL errors. (check-in: fd578a32 user: drh tags: trunk)

2011-02-18
17:23		Fix the sqlite3ValueFromExpr() routine so that it returns SQLITE_NOMEM on an OOM when trying to extract a NULL. (check-in: 1061e94f user: drh tags: trunk)
2011-02-17
15:58		Remove a no-op code path from sqlite3ExprIsInteger(). Replace it with an assert() that proves it always does nothing. (check-in: 7af66d1b user: drh tags: trunk)
13:52		Remove an assert() that was made redundant by the previous checkin. (check-in: 21db7191 user: drh tags: trunk)
13:33		Add an ALWAYS() around a always-true test in where.c. (check-in: 8123283e user: drh tags: trunk)
2011-02-16
23:32		Fix harmless compiler warnings in the query planner. (check-in: 31fc4ba6 user: drh tags: trunk)

2011-02-14
03:49		Skip some tests in capi3e.test when compiled with SQLITE_OMIT_UTF16. (check-in: b04304b9 user: shaneh tags: trunk)
2011-02-12
14:23		Fix the expected output on tests so that it corresponds to the new query planner results. All of veryquick.test is now passing with SQLITE_ENABLE_STAT2. (check-in: f2a8b5cc user: drh tags: branch-3.7.2)
05:34		Fix problems in the backport, reducing the number of errors in the TCL tests to just a few dozen. Most of the remaining errors seem to be real and desirable changes of behavior. (check-in: 9d2b0af2 user: drh tags: branch-3.7.2)
01:59		This is the beginning of an attempt to backport recent query planner enhancements to version 3.7.2. The code in this version builds and runs and seems to give correct answers, but it generates suboptimal query plans and hence many of the test cases fail. The test script gives up after 1000 errors. (check-in: e72cf118 user: drh tags: branch-3.7.2)
2011-02-11
22:54		Add a NEVER() around a test that is believed to always be false. (check-in: f7e2ea33 user: drh tags: trunk)
20:52		Skip flattening if subquery has LIMIT and outer query is DISTINCT. Fix for ticket [752e1646fc]. (check-in: 55973999 user: shaneh tags: trunk)
06:59		Fix a bug in the new WHERE-clause processing that tries to use an index to resolve IS NOT NULL constraints when SQLITE_ENABLE_STAT2 is defined. The bug could cause memory overruns and segfaults. The bug was new to the code and has not appeared in an official release. Found during structural testing. (check-in: a5c36b9f user: drh tags: trunk)
03:56		Allow an index paired with an IS NULL constraint to be used for sorting under the condition that the index be treated as a non-unique index. (check-in: d78949fc user: drh tags: trunk)
02:43		Disable unused NULL tests when SQLITE_ENABLE_STAT2 is not in use. (check-in: 5ecd1178 user: drh tags: trunk)
2011-02-10

17:46		Prevent a segfault when automatic indices try to use a column with an unknown collating function. Ticket [77aa3b1e6592582e38605d36]. This check-in also removes some stray \r characters unrelated to the problem. (check-in: f01030a0 user: drh tags: trunk)
01:49		This is a version of the SQLite 3.7.5 release with Apple's changes for MacOS. (check-in: 55d2e55b user: drh tags: apple-osx)

2011-02-09
19:55		Make sure code *compiles* with each OMIT and ENABLE option. Mostly changes to test modules. (check-in: 7cc515ed user: shaneh tags: trunk)
18:19		Do not report corruption if the the db size header field is greater than the file size on disk unless the two change-counter header fields are identical. Fix for ticket [89b8c9ac54]. (check-in: 00c4596f user: dan tags: trunk)
15:25		Update Makefile.in for fts3_aux changes. (check-in: 38b7cb33 user: shaneh tags: trunk)
03:04		Use macros to define the relative costs of search and seek operations when computing costs in the query planner. Current constants seems wrong and need to be fixed, but doing so will alter test results. Need more experimentation to determine accurate relative costs. (check-in: 5f2ec44b user: drh tags: trunk)
03:03		Simplifications to the sqlite3_wal_checkpoint_v2() logic. (check-in: 652b8835 user: drh tags: trunk)
2011-02-07
23:56		Cleanup to the OP_Checkpoint opcode. (check-in: f611a5a8 user: drh tags: trunk)
16:24		Fix some test cases in walfault.test. Extend one test case to restore code coverage. Add wal5.test to the "coverage-wal" permutation. (check-in: f83b07ac user: dan tags: trunk)
15:12		Change blocking-checkpoint tests so that they run once using "PRAGMA wal_checkpoint" and once using calls to sqlite3_wal_checkpoint_v2(). Also fix edge cases surrounding the output variables set by wal_checkpoint_v2(). (check-in: 5a4b6652 user: dan tags: trunk)
2011-02-05
15:47		Ensure fts4aux can handle a table name in single or double quotes as a constructor argument. (check-in: 929d62e4 user: dan tags: trunk)
14:37		Add test cases for fts4aux. Fix a bug affecting fts3 tables with multiple columns. (check-in: dc511e60 user: dan tags: trunk)
2011-02-04

14:28		Significant changes have occurred since the 3.7.5 release so go ahead and increase the version number to 3.7.6. (check-in: 999c915a user: drh tags: trunk)
06:36		Merge the stat2 query planner enhancements into the trunk. (check-in: 499edcbc user: drh tags: trunk)
05:47		If a deferred foreign key constraint fails on a statement that is not part of a larger transation, make sure that the statement fully ends so that subsequent invocations of the same statement will not pass the constraint because they think the transaction is not closed. This is a merge of the deferred-fk-quirk branch together with a test case. (check-in: 2f94d462 user: drh tags: trunk)
00:51		Fix the ATTACH command so that the filename argument can be any expression and so that if authorizer callback gets a NULL pointer for the filename if the filename argument is anything other than a string literal. Ticket [9013e13dba5b58c7] (check-in: e64e1453 user: drh tags: trunk)

2011-02-01
18:59		Remove extra instances of the text "checked out." from sqlite.h.in. Also add new file fts3_aux.c to mksqlite3c.tcl. (check-in: 9897da22 user: dan tags: fts4aux)
18:00		Fix a problem causing builds with SQLITE_OMIT_WAL defined to fail. (check-in: b9b48dd8 user: dan tags: fts4aux)
17:55		Fix a case in fts4 where a corrupt %_stat table could lead to a crash. (check-in: 4ade96ce user: dan tags: fts4aux)
16:34		Add virtual table module "fts4aux", used to inspect the full-text index of an fts4 table directly. Also add the "compress" and "uncompress" fts4 options. (check-in: b010ddcc user: dan tags: fts4aux)
00:04		Version 3.7.5 (check-in: ed759d5a user: drh tags: trunk, release, version-3.7.5)
2011-01-28
17:02		Bogus release candidate. (Closed-Leaf check-in: 38ca1daa user: drh tags: mistake)
16:45		Add test script pagerfault3.test. No changes to code or existing tests. (check-in: 682fe41e user: dan tags: trunk)
15:46		Change pager_truncate() to a different method for extending files while also ensuring that writes are page-size and page-aligned. (check-in: 874bc884 user: drh tags: trunk)
15:07		When extending a database file, do so by writing one or more page-size chunks of data to the file, instead of just a single byte to the end. (check-in: 58577135 user: dan tags: trunk)
03:13		Reactivate the analyze5.test script. (Closed-Leaf check-in: a2a9f640 user: drh tags: stat2-enhancement)
01:57		Change the weighting of binary searches on tables to 1/10th the cost of a search on an index. Change the assumed reduction in search space from a indexed range constraint from 1/3rd to 1/4th. Do not let the estimated number of rows drop below 1. (check-in: 4847c6cb user: drh tags: stat2-enhancement)
2011-01-27
18:48		Pull in all the changes from trunk up through the version 3.7.5 release candidate 1. (check-in: 09d6c91d user: drh tags: apple-osx)
14:35		SQLite version 3.7.5 release candidate 1 (check-in: 35ac78f5 user: drh tags: trunk)
2011-01-26
19:46		Update all built-in VFSes to return SQLITE_OK for the SQLITE_FCNTL_SYNC_OMITTED file-control operation. Also change the xFileControl methods to return SQLITE_NOTFOUND for unrecognized operation codes. (check-in: 6f2c72a0 user: drh tags: trunk)
15:23		Update test file mutex1.test to account for [e3b500fb5d]. (check-in: c86e46f4 user: dan tags: trunk)
13:28		More mutexes around another sqlite3StatusAdd() call. (check-in: e3b500fb user: drh tags: trunk)
13:24		Add a mutex around an sqlite3StatusAdd() call to prevent the pagecount overflow measurements from getting off in multithreaded applications. (check-in: 3d8b298d user: drh tags: trunk)
07:25		Update mutex1.test so that it works with the memsubsys1 permutation (pagecache memory). Change a few instances of SQLITE_MUTEX_STATIC_LRU2 in comments and test code to STATIC_PMEM. (check-in: 456bd5c6 user: dan tags: trunk)
06:13		Changes to exclusive2.test to make it more deterministic. (check-in: 84b0c2bc user: dan tags: trunk)
00:07		Rename the PCache1.mxPinned field to n90pct (since it is 90% of nMax) in order to distinguish it from PGroup.mxPinned. Fix the computation of n90pct so that it does not overflow adversely on excessively large cache sizes. (check-in: c85202ba user: drh tags: trunk)
2011-01-25
18:30		Fix new compiler warnings in pcache1.c that were introduced by the recent performance enhancement patches of [e14649301138b684]. (check-in: c17703ec user: drh tags: trunk)
18:19		Add a missing call to sqlite3PagerSync() removed by [ce552d975] to the backup code. (check-in: 1965b853 user: dan tags: trunk)
16:48		Make sure the return code from doing an xSync is correctly initialized so that a valid return code is produced regardless of the path taken through the logic. (check-in: f12b5d76 user: drh tags: trunk)
16:20		Change the name of SQLITE_FCNTL_SYNC to SQLITE_FCNTL_SYNC_OMITTED and only send it when PRAGMA synchronous=OFF. Add better documentation to explain what that file-control opcode is used for. (check-in: 64914980 user: drh tags: trunk)
13:43		Fix a couple of typos in comments. No changes to actual code. (check-in: 9167fdb3 user: dan tags: trunk)
11:33		Fix a broken assert() in pager.c. (check-in: 13108ce1 user: dan tags: trunk)
09:54		Fix a problem in memsubsys1.test. Modifications to test code only. (check-in: 7ef3f7cb user: dan tags: trunk)
04:34		Shave a few cycles so that performance is better than 3.7.4 in speed tests. (check-in: e1464930 user: drh tags: trunk)
2011-01-24

19:45		Fix a typo in the documentation for sqlite3_snprintf(). No changes to code. (check-in: 8d106541 user: drh tags: trunk)
19:14		Fix a harmless compiler warning (a shadowed local variable) in analyze.c. (check-in: a1ad7fb3 user: drh tags: trunk)
17:46		Restructuring and generalizing analyze5.test. The whole script is currently disabled and will need to be reenabled prior to merging with trunk. (check-in: 31fcc706 user: drh tags: stat2-enhancement)
16:00		Ensure that if a deferred FK constraint is violated by a statement that creates its own implicit transaction, the statement is not an "active-write" after sqlite3_step() returns. (Closed-Leaf check-in: 8063197e user: dan tags: deferred-fk-quirk)
15:11		Change the cost estimator in the query planner to take into account the logN rowid lookup cost when going from an index to a table. (check-in: b442525b user: drh tags: stat2-enhancement)
2011-01-22
13:32		Modify the trace callback mechanism so that SQL commands executed from within virtual table or user function callbacks are passed to the trace callback without parameter expansion and enclosed in SQL comments. (check-in: a764915b user: dan tags: trunk)
00:10		Add the ability to use indices for constraints of the form "x IS NOT NULL" when sqlite_stat2 is available and most entries for column x are NULL. (check-in: 5d5bddd2 user: drh tags: stat2-enhancement)
2011-01-21
18:25		Change sqlite3StrAccumAppend() to use realloc instead of malloc. (check-in: 380f61df user: dan tags: trunk)
18:18		Adjustments to the result row estimator for the IN operator so that it gives the same estimates as the equivalent OR operator. Test cases for the same. (check-in: c82cb9c0 user: drh tags: stat2-enhancement)
16:27		Make use of histogram data to make better estimates for the number of rows that will be returned from "x IN (v1,v2,v3,...)" constraints. (check-in: fd3977a2 user: drh tags: stat2-enhancement)
15:52		Add options to test command [do_faultsim_test] to support testing VFS implementations. (check-in: 503ad889 user: dan tags: trunk)
14:37		Add the ability to use indices when a range contraint is bounded on the lower end by NULL. (check-in: f73a167b user: drh tags: stat2-enhancement)
2011-01-20
20:36		Update ANALYZE test cases to check out the use of histograms for equality constraints. (check-in: c7b59afa user: drh tags: stat2-enhancement)
16:52		Use histogram data to improve the row-count estimates on equality constraints. (check-in: 6bfc5c69 user: drh tags: stat2-enhancement)
02:56		The first of a planned series of enhancements to the query planner that enable it to make better use of sqlite_stat2 histograms when the table has many repeated values. (check-in: 2cd374cd user: drh tags: stat2-enhancement)
2011-01-19
21:58		Comment improvements in pcache1.c. No changes to code. (check-in: 9660a0a2 user: drh tags: trunk)
2011-01-18
17:34		Pull over all the latest trunk changes. (check-in: ca86d04b user: drh tags: wal-trace-375)
17:03		Do not use mutexes in the pcache implementation unless SQLITE_ENABLE_MEMORY_MANAGMENT is defined. This is a performance enhancement. A side effect is that pcaches will not steal pages from one another unless ENABLE_MEMORY_MANAGEMENT is set, or unless SQLITE_THREADSAFE=0. (check-in: e5ca59e6 user: drh tags: trunk)
16:13		Get all test cases working with the mutex-free-pcache implementation. (Closed-Leaf check-in: 2dc98d29 user: drh tags: mutex-free-pcache)
15:17		Do not use SQLITE_MUTEX_STATIC_MEM2 since it has been reused as STATIC_OPEN. Instead, create a new static mutex STATIC_PMEM which is an alias for the unused STATIC_LRU2. (check-in: f1cf02ef user: drh tags: mutex-free-pcache)
2011-01-17
21:32		Here is a completely new implementation of the mutex-free-pcache. This one uses a common code base and automatically selects whether or not to use mutexes depending on compile-time and start-time options. (check-in: d094a1bf user: drh tags: mutex-free-pcache)
18:30		Fix a typo in the documentation for sqlite3_stmt_readonly(). (check-in: 56417a33 user: drh tags: trunk)
17:42		Add the SQLITE_OMIT_AUTORESET compile-time option which if enabled causes the sqlite3_step() routine to return SQLITE_MISUSE if it is called after it has previously returned anything other than SQLITE_ROW, SQLITE_BUSY, or SQLITE_LOCKED. (check-in: 053ce76d user: drh tags: trunk)
02:24		Add back an ALWAYS() to regain full test coverage. (check-in: b93f6f3e user: drh tags: trunk)
2011-01-16
22:37		On a backup from a smaller to a larger page size, do not begin committing the transaction until the source pages after the pending byte have been copied. (check-in: 612e2599 user: drh tags: trunk)
00:56		Make sure the change-counter and SQLite-version fields of the header are set correctly even when doing a VACUUM with locking_mode=EXCLUSIVE. Ticket [5d863f876ee9561b]. (check-in: 04fa1e16 user: drh tags: trunk)
2011-01-15
21:42		Make sure the change counter and SQLite version numbers in the header are set correctly, even when running in WAL mode and when VACUUMing in WAL mode. Ticket [5d863f876ee9561b9]. (check-in: 0be92a75 user: drh tags: trunk)
18:11		Fix the change-counter increment for WAL pages so that it works even when invoked from xStress. Ticket [5d863f876ee9561b95e2]. (Closed-Leaf check-in: 228e7c34 user: drh tags: bug-5d863f87)
17:12		Increment the change counter and update the SQLite version number whenever page 1 is added to the WAL. Ticket [5d863f876ee9561b9] (check-in: c1e0d09c user: drh tags: bug-5d863f87)
16:52		Add a test case demonstrating the problem described by ticket [5d863f876e]. (check-in: af54963f user: dan tags: trunk)
2011-01-14
16:43		Rerun autoconf to bring the configure script up-to-date. (check-in: 14217464 user: drh tags: trunk)
16:12		Provide an alternative and experimental pcache implementation that avoids the use of mutexes at the expense of using more memory. (Closed-Leaf check-in: 2ea5bd12 user: drh tags: mutex-free-pcache)
15:17		Fix comments, including some documentation comments, in the page cache logic. No code changes. (check-in: c80e9c1a user: drh tags: trunk)
11:51		Fix a bug in test code (test_vfs.c). (check-in: 772a3845 user: dan tags: trunk)
2011-01-13
16:10		Fix a typo on the sqlite3_open_v2() documentation. (check-in: b0add45a user: drh tags: trunk)
11:20		Fix a couple of crashes in fts3 that can occur if the database contents are inconsistent. (check-in: 811e12cd user: dan tags: trunk)
10:58		Fix a segfault that can occur in matchinfo if an fts4 table contains mostly zero-length documents. Specifically, if the table contains more rows than it does bytes of text. (check-in: fe904766 user: dan tags: trunk)
2011-01-12
17:56		Do not raise an SQLITE_CORRUPT error in Recoverymode if the database size in the header is larger than the physical file size. This facilitates recovery of a database in which the database size field has been corrupted. (check-in: 114640d9 user: drh tags: trunk)
2011-01-11
17:40		Merge accidentally created fork. (check-in: b7d080b8 user: dan tags: trunk)
17:39		Add the SQLITE_FCNTL_SYNC file-control. (check-in: b3f2f465 user: dan tags: trunk)
17:38		Change the page size of the destination database in a backup, if it is changeable, prior to starting the backup. (check-in: a5e4e0ca user: drh tags: trunk)
16:09		If a rollback is attempted in journal_mode=off mode, force SQLite to discard the contents of the pager cache before processing any subsequent queries. (check-in: ece7efce user: dan tags: trunk)
12:46		Fix the sqlite3.h generator script so that it generates the correct SQLITE_SOURCE_ID string with the latest versions of Fossil that include fractional seconds on the date/time stamp. (check-in: 3513bf6e user: drh tags: trunk)
01:42		A proposed change to the sqlite3_step() API such that it will only auto-reset following an SQLITE_BUSY or SQLITE_LOCKED error. Calls after any other result other than SQLITE_ROW will return SQLITE_MISUSE. (Closed-Leaf check-in: d1b3c54f user: drh tags: step-autoreset)
2011-01-10
21:01		Update pager requirements to account for the ZIPVFS extension. (check-in: d94e59b5 user: drh tags: trunk)
2011-01-07
02:50		Reorder the fields in private structures in an effort to reduce alignment gaps and thus make the structures smaller, and to put frequently accessed fields first. Also update some obsolete comments. Valgrind shows a very slight performance improvement. (check-in: 378a1d13 user: drh tags: trunk)
2011-01-06
15:51		Enhance the showdb tool to show overflow page pointers at the end of overflow cells. (check-in: cda5eab1 user: drh tags: trunk)
01:26		Enhance the showdb tool to show a btree page layout. Add limit checks so that overflow content does not overflow the buffer. (check-in: 57ffa07e user: drh tags: trunk)
2011-01-05
21:46		Fix a bug in the showdb utility: the serial types for BLOB and TEXT where reversed. (check-in: 65a13faf user: drh tags: trunk)
21:20		Enhancements to the "showdb" debugging tool. Add the ability to display the content of a cell. (check-in: e9023a4e user: drh tags: trunk)
13:43		Increment the version number to 3.7.5. (check-in: 9ec3896e user: drh tags: trunk)
13:07		Cherrypick the WAL error logging from the pre-3.7.5 line into a branch for version 3.7.2. Include the sqlite3_vsnprintf() interface. This checkin is intended for debugging and not for release. (Leaf check-in: 6549e767 user: drh tags: wal-trace-372)
12:50		Add detailed error logging to WAL in an effort to track down an obscure SQLITE_PROTOCOL problem. This code is intended for debugging and not for release. (check-in: 2c2afdd0 user: drh tags: wal-trace-375)
12:20		Add the sqlite3_vsnprintf() interface. (check-in: fc67adea user: drh tags: trunk)
2011-01-04
20:06		Fix a null-pointer dereference that can occur on an OOM error while running ANALYZE with SQLITE_ENABLE_STAT2. (check-in: 73128d4e user: drh tags: trunk)
19:01		Fix the ANALYZE command so that it takes collating sequences into account when gathering index statistics. (check-in: a5867cfc user: drh tags: trunk)
17:57		The ANALYZE command now counts at all rows of an index, even those containing NULL values. A valid sqlite_stat1 entry is created even if the index contains nothing but NULLs. (check-in: 824c8dd3 user: drh tags: trunk)
2010-12-29
18:24		Have testfixture invoke C routine Zipvfs_Init() when creating a new interpreter if SQLITE_ENABLE_ZIPVFS is defined. (check-in: 430635da user: dan tags: trunk)
10:49		Fix some off-by-one errors in the comments for API functions create_function() and value_blob(). No changes to code or tests. (check-in: 7ded90ba user: dan tags: trunk)
2010-12-24
15:49		Reduce the number of calls to sqlite3_realloc() made by fts3 when querying for position information of a term prefix. (check-in: 7088d945 user: dan tags: trunk)
2010-12-22
21:48		Do not include <sys/mmap.h> if SQLITE_OMIT_WAL is defined. (check-in: b82e85ec user: drh tags: trunk)
2010-12-21
21:28		Add test cases for the new lookaside hit and miss status outputs. Add the output of lookaside hit and miss to the command-line shell statistics. (check-in: b0888047 user: drh tags: trunk)
20:36		Merge into the trunk the experimental enhancements to sqlite3_db_status() for measuring lookaside memory allocator performance. (check-in: 8c3b06c2 user: drh tags: trunk)
00:20		Remove the obsolete compile-time option SQLITE_THREAD_OVERRIDE_LOCK from the autoconf makefile. Needed only for LinuxThreads, which we no longer support. (check-in: 09f6c053 user: drh tags: trunk)
00:16		Rearrange a variable declaration in the proxy locking code to avoid a harmless compiler warning on recent MacOS versions. (check-in: 39bbd355 user: drh tags: trunk)
2010-12-20
17:00		Clarify the documentation of the SQLITE_STATUS_MALLOC_COUNT parameter to sqlite3_status(). (check-in: 3b41bcc3 user: drh tags: trunk)
15:51		Add additional DBSTATUS options for measuring the hit and miss rates against the lookaside memory pool - information useful in tuning the lookaside size. Currently experimental pending analysis of performance impact. (Closed-Leaf check-in: 34613f1d user: drh tags: experimental)
2010-12-17
14:03		Add the "-heap" option to the command-line shell - to allocate a fixed heap for use with SQLITE_ENABLE_MEMSYS5. (check-in: 74fff692 user: drh tags: trunk)
01:00		Fix minor typos in the sqlite3_backup documentation. (check-in: df430be5 user: drh tags: trunk)
2010-12-16
20:35		Improvements to the documentation for sqlite3_backup. No code changes. (check-in: f83609f4 user: drh tags: trunk)
19:52		Fix an assertion fault that can only occur if SQLITE_ENABLE_STAT2 is defined and the constant folding optimization is disabled using sqlite3_test_control(). Problem introduced by [ad8bc68197f2b4] but we missed it prior to the 3.7.4 release due to taking shortcuts and skipping tests in the release checklist. (check-in: 70a3d817 user: drh tags: trunk)
02:06		Make wal_checkpoint a no-op if a prior checkpoint has already copied all WAL content into the database. This prevents a concurrent write to the database from resetting the wal-index out from under the WalIterator of the checkpoint as it is initializing. (check-in: cf86affc user: drh tags: trunk)
2010-12-15
21:02		Enhanced comments in wal.c and declare some procedure parameters "const". No changes to the generated code. (check-in: d0e4375b user: drh tags: trunk)
18:54		When registering the built-in LIKE and GLOB functions, make sure that they are tagged with SQLITE_UTF8 so that if other application-defined LIKE and GLOB implementations are provided for UTF16, then the appropriate function will be selected. (check-in: e1660764 user: drh tags: trunk)
2010-12-10
17:06		Fix a performance regression in matchinfo(). (check-in: fa37d8eb user: dan tags: trunk)
2010-12-09
19:15		Add support for the SQLITE_DEFAULT_FOREIGN_KEYS compile-time option. (check-in: c959945a user: drh tags: trunk)
18:55		Mention the SQLITE_DEFAULT_WAL_AUTOCHECKPOINT compile-time option in the documentation for the sqlite3_wal_autocheckpoint() interface. (check-in: 5a52dd59 user: drh tags: trunk)
2010-12-08
18:30		Update the sqlite3_stmt_readonly() interface so that its output is well-defined for all prepared statements, and so that it gives the correct result for VACUUM. (check-in: 9c19b7ae user: drh tags: trunk)
03:28		The command-line shell ignore errors in sqlite3_close() when shutting down. (check-in: 925332c3 user: drh tags: trunk)
00:02		Changes to the shell which should, in theory, allow it to work with libeditline as an alternative to libreadline. (check-in: e474fd9e user: drh tags: trunk)
2010-12-07
23:24		Improved documentation for SQLITE_FCNTL_FILE_POINTER. (check-in: 43935548 user: drh tags: trunk)
20:14		Version 3.7.4 (check-in: a586a4de user: drh tags: trunk, release, version-3.7.4)
17:12		Work around restriction in Windows file locking. (check-in: fe441df9 user: shaneh tags: trunk)
16:39		Fix a bug in the demo "superlock" code preventing locks from being released in some circumstances. (check-in: 65c39379 user: dan tags: trunk)
15:49		Merge in all changes to the trunk through version 3.7.4rc3. (check-in: d2ccf7fc user: drh tags: apple-osx)
14:59		Version 3.7.4 release candidate 3 (check-in: 11c74c0d user: drh tags: trunk)
14:32		Run some of the existing test scripts with optimizations disabled as part of all.test. (check-in: b0634d2f user: dan tags: trunk)
07:57		Add tests to tkt-80ba201079.test. (check-in: c370338c user: dan tags: trunk)
2010-12-06
21:09		Fix the build so that it once again works with SQLITE_OMIT_SHARED_CACHE and SQLITE_OMIT_AUTOVACUUM. (check-in: fabcb6b9 user: drh tags: trunk)
21:06		Add the ability to disable constant factoring using sqlite3_test_control(). Add a TCL interface to this new capability and add tests cases to the TCL test scripts to actually use the new capability. (check-in: ad8bc681 user: drh tags: trunk)
18:59		Back out part of the previous change that was not really necessary in order to fix [80ba201079ea60], and which in fact serves no useful purpose. (check-in: fa9eef86 user: drh tags: trunk)
18:50		Initialize all constants at the very beginning of a prepared statement. Do not allow constant initialization to occur once control flow has a chance to diverge, to avoid the possibility of having uninitialized registers. Ticket [80ba201079ea60807]. (check-in: c5c53152 user: drh tags: trunk)
17:11		Have sqlite3_blob_bytes() return 0 following a failed call to sqlite3_reopen_blob(). (check-in: 476a8b49 user: dan tags: trunk)
2010-12-04
19:35		Version 3.7.4 release candidate 2. (check-in: 40756fe1 user: drh tags: trunk)
18:20		Fix a memory leak in fts3 that can occur in an OOM condition. (check-in: 507027b7 user: dan tags: trunk)
2010-12-03
18:57		Remove an over-zealous call to memAboutToChange() from OP_MustBeInt. OP_MustBeInt will never invalidate the Mem.z pointer so the memAboutToChange() call is not necessary. (check-in: 841cf7a7 user: drh tags: trunk)
15:41		Version 3.7.4 release candidate 1 (check-in: 2e800cb8 user: drh tags: trunk)
15:04		Add tests for fts3 to backcompat.test. (check-in: b4eafde8 user: dan tags: trunk)
10:32		Add the "valgrind" permutation. This is the same as veryquick.test except that it omits the multi-process tests that do not work under valgrind. No changes to production or existing test code. (check-in: 49531300 user: dan tags: trunk)
2010-12-02
17:39		Fix a bug causing fts3 to incorrectly return SQLITE_CORRUPT. (check-in: 099195b1 user: dan tags: trunk)
14:47		Exclude a test case from the inmemory_journal permutation of multiplex.test. (check-in: 474196d6 user: dan tags: trunk)
11:24		Fix a (harmless) valgrind warning in the rtree extension. (check-in: a94b9a39 user: dan tags: trunk)
06:08		Update misc7.test to account for EQP changes. (check-in: 917af565 user: dan tags: trunk)
2010-12-01
23:42		Changed multiplex shim's xFilesize to return an error on mismatched chunk size. Added test of same. (check-in: 6818c6e4 user: shaneh tags: trunk)
22:08		Make sure a test of multiplex shim doesn't fail if a file already exists. (check-in: 80de240a user: shaneh tags: trunk)

06:22		Add tests to walmode.test. (check-in: 5aa2bdb5 user: dan tags: trunk)
03:13		Changes to os_win.c to have it simulate IO errors like os_unix.c. (check-in: 0d53da94 user: shaneh tags: trunk)
2010-07-07
21:06		Make the initial salt values in the WAL header random values, not zero. (check-in: baa5eddd user: drh tags: trunk)

13:54		Make sure the schema is loaded before preparing a "PRAGMA journal_mode" command. This helps it return meaningful results when it is the first command executed by a new database connection. (check-in: ef126e77 user: dan tags: trunk)
13:43		Add testcase macros to ensure that large-file cases are tested in WAL. (check-in: 8156b57a user: drh tags: trunk)
11:43		Run some fts3 tests as part of the "wal" permutation. (check-in: 8657455a user: dan tags: trunk)
11:05		Change the async-IO extension to return SQLITE_IOERR_SHORT_READ when appropriate. This prevents a valgrind warning in the test suite. (check-in: d9e32879 user: dan tags: trunk)
09:48		Fix a problem with writing to databases larger than 2^32 bytes with WAL mode. (check-in: b956ddca user: dan tags: trunk)
01:52		Remote the SQLITE_OMIT_GLOBALRECOVER macro - it is subsumed by SQLITE_OMIT_DEPRECATED. Add support to sqlite3_compileoption_used() for SQLITE_OMIT_WAL. (check-in: 21a2db90 user: drh tags: trunk)
2010-07-06
20:37		Minor changes to Makefile.in to bring it more inline with main.mk. (check-in: 5621862b user: shaneh tags: trunk)
20:34		Changes to pager1.test to support Windows. (check-in: fce689eb user: shaneh tags: trunk)
20:33		Modified the xWrite() method on Windows to differentiate between IO and disk full error returns. (check-in: ca4b7ffb user: shaneh tags: trunk)
11:26		Do not do the *-closeallfiles test for notify2.test. It uses multiple threads. (check-in: fb09152d user: dan tags: trunk)
10:55		Before calling Tcl_ExitThread() in a multi-threaded test, call Tcl_DoOneEvent() as many times as necessary to handle any queued events. (check-in: b3399b40 user: dan tags: trunk)
09:29		Reorder variable declarations in the previous check-in to avoid putting code before declarations when not testing. (check-in: d1fe8ab4 user: drh tags: trunk)

2010-07-05
21:00		Modify the VFS xAccess() method on winNT so that it returns false for an exists test of a zero-length file. This makes the windows VFS work the same as the unix VFS. (check-in: ec35f254 user: drh tags: trunk)
19:13		Simplify the previous commit by removing the pagerCheckForOrDeleteWAL() wrapper. (check-in: a1324d12 user: dan tags: trunk)
19:03		Allocate a buffer containing the full path-name to the associated WAL file when a pager is created. This saves having to construct a new buffer each time a new read-transaction is opened and SQLite checks for the existance of a WAL file. (check-in: 3053a4ad user: dan tags: trunk)
17:43		When rolling back page 1 from a journal, restore the "nReserve" setting in case it has been corrupted by a prior crash. (check-in: c0d124da user: drh tags: trunk)
14:54		Do not report an error if the open-file-count is not as it should be after running a multi-threaded test. The counter instrumentation is not thread-safe. (check-in: ea80b21c user: dan tags: trunk)
12:54		Call Tcl_ExitThread() from within threads created using Tcl_CreateThread(). Not doing so causes notifier related errors on OSX. (check-in: 684eae66 user: dan tags: trunk)
05:54		Add any files specified as part of the QUICKTEST_INCLUDE environment variable to the set of test files run as part of "make test". Release testing uses this trick. (check-in: a40a6e7d user: dan tags: trunk)
05:31		Fix typos in permutations.test. (check-in: b6600ecb user: dan tags: trunk)
2010-07-03

08:01		Do not attempt to open a WAL file for an in-memory or temporary database. Even if the database header suggests that it is a WAL database. (check-in: 0fd80924 user: dan tags: mistake)
05:56		Change code in OP_Rewind to avoid a valgrind warning following an error in the btree layer. This change does not fix any bug, just a warning. (check-in: 4f62dbcf user: dan tags: mistake)
01:44		Fix a buffer overrun in the where.c. Problem detected by valgrind. (check-in: 15bb6233 user: drh tags: mistake)
2010-07-02
19:49		Changes to os_win.c to have it return same error code as os_unix.c. (check-in: 33b6f069 user: shaneh tags: mistake)
19:36		Omit the OP_JournalMode opcode from the VDBE when SQLITE_OMIT_PRAGMA is defined. (check-in: 565ff65c user: drh tags: mistake)
19:04		Fix a bug in test_vfs.c causing an assert to fail. Changes to test code only. (check-in: 336ce7d2 user: dan tags: mistake)
18:58		Do not run the tests in notify3.test unless the unlock-notify API is available. (check-in: 0d7fd6fe user: dan tags: mistake)
18:44		Take out the incomplete initializer on the constant "dummy" in sqlite3VdbeGetOp(). Add a comment that the MSVC warning there should be ignored. (check-in: 452ccaa9 user: drh tags: mistake)
18:15		Fix a couple more compiler warnings under MSVC. (check-in: 26bc27e3 user: shaneh tags: mistake)

17:07		Remove a couple of C++ style comments from pager.c. (check-in: 4f12e8eb user: drh tags: mistake)
17:05		Fix some warnings when compiling under MSVC. (check-in: 70833877 user: shaneh tags: mistake)
16:36		Add initializers for the xShmXXX() members to an sqlite3_io_methods structure in journal.c. This doesn't fix any real problem, just prevents a compiler warning. (check-in: dafb3577 user: dan tags: trunk)
15:35		Remove an unused call to sqlite3PageBegin() from pager_write(). Replace it with an assert(). (check-in: 01c12782 user: drh tags: trunk)
13:49		Run tkt-9d68c883.test along with the other pager.c coverage tests. Add a test case to pager1.test. (check-in: c6714b0d user: dan tags: trunk)
11:27		Additional test cases to cover branches in pager.c. (check-in: eddfb2b4 user: dan tags: trunk)
01:18		Add a NEVER to sqlite3PagerCommitPhaseTwo() because it is now no longer possible to invoke that function without holding a RESERVED lock. (check-in: 6ae76172 user: drh tags: trunk)
2010-07-01
19:45		If you delete a database file but not its *-wal file, then open the database (thus creating a new empty database file) the *-wal file is automatically deleted. (check-in: 95c69dfb user: drh tags: trunk)
19:01		Add tests to pager1.test and pagerfault.test. (check-in: c6e75950 user: dan tags: trunk)

10:36		Add further test cases. Fix an assert() in pager.c. (check-in: 8e65c0e3 user: dan tags: trunk)
04:36		Do not call pager_open_journal() from within PagerBegin() if the connection is in exclusive-access mode. It will be called from within PagerWrite() just as it is for non-exclusive mode anyway. (check-in: cdf2c5c2 user: dan tags: trunk)
04:29		Add coverage test cases. Have sqlite3_backup_step() transform SQLITE_IOERR_NOMEM to SQLITE_NOMEM before returning. (check-in: 5e19bc36 user: dan tags: trunk)
2010-06-29
10:30		Add tests to pager1.test and pagerfault.test. (check-in: 008513ee user: dan tags: trunk)

11:23		Fix some errors when compiling with SQLITE_OMIT_WAL. (check-in: 3b68cb9c user: dan tags: trunk)
11:06		Remove debugging code from test script. (check-in: a85ae332 user: dan tags: trunk)
10:15		Currently, if SQLite cannot find a table or index referred to by a query, it reloads the database schema from disk to see if the table or index has been added since the schema was cached in memory. Extend this behaviour to columns (which may have been added using ALTER TABLE) and fix some obscure cases related to tables and indexes (INDEXED BY, DROP TABLE etc.). (check-in: 4932f228 user: dan tags: trunk)
2010-06-26
22:16		Make walIndexTryHdr() a private function. Fix an issue with SQLITE_MUTEX_NOOP. (check-in: ec65bbd0 user: drh tags: trunk)

20:00		Suppress a couple uninitialized variable warnings. (check-in: 29571e22 user: drh tags: trunk)
19:03		Add test file tkt-d11f09d36e.test. (check-in: 6e469b63 user: dan tags: trunk)
19:02		Remove a NEVER() in pager that can in fact be reached in obscure failure cases. (check-in: 42b8bd1c user: drh tags: trunk)
17:15		Fix a case where the doNotSyncSpill flag may remain permanently set following an IO error. (check-in: 56c7d111 user: dan tags: trunk)
15:42		When synchronous=NORMAL, use the same journal file format as with synchronous=FULL (i.e. multiple journal headers within the one journal). Fix for [d11f09d36e]. (check-in: 2eaf5ee0 user: dan tags: trunk)
2010-06-25
19:09		Further test cases for pager1.test and pagerfault.test. (check-in: bfd563c4 user: dan tags: trunk)
16:34		Reduce the average (but not maximum) size of the allocations made as part of a checkpoint. (check-in: 4a7fd91b user: dan tags: trunk)
15:16		Reduce the size of the large allocation (approx 8KB for every 4000 frames in the log) that occurs during checkpoint. Use the 'scratch' memory for this allocation instead of the general purpose allocation. (check-in: 29887487 user: dan tags: trunk)
14:17		Fix up a branch in sqlite3ValueFromExpr() so that we can achieve full branch test coverage regardless of whether or not SQLITE_ENABLE_STAT2 is used. (check-in: af471ed7 user: drh tags: trunk)
12:52		Change the name of the shared-memory file on windows from *-wal-index to *-shm, for consistency with unix. (check-in: 5995cb15 user: drh tags: trunk)
11:35		Modify the merge-sort in wal.c so that it does not use recursion. (check-in: daea6c05 user: dan tags: trunk)
2010-06-24
19:16		Add test cases to pager1.test and pagerfault.test. (check-in: 4941e437 user: dan tags: trunk)
18:36		Revert to allowing a cache spill during writes of multiple pages within a single sector as long as the spill does not require a journal sync and a new journal header. (check-in: 7d83fbae user: drh tags: trunk)
17:37		Modify ctime.test to work with SQLITE_THREADSAFE=2. (check-in: c6db3b30 user: dan tags: trunk)
14:52		Disable memory-pressure induced cache spill during savepoint rollback. (check-in: a55eb4c3 user: drh tags: trunk)
13:24		Add a coverage test to pagerfault.test. (check-in: b58db67e user: dan tags: trunk)
10:50		Add coverage tests. Remove a NEVER macro from pager.c, as the condition can now be true in wal mode. (check-in: 7aac9ad6 user: dan tags: trunk)
02:46		Make sure the wal-index reader detects an incorrect version number even if it had to hold a lock in order to read the wal-index. Also, expand and enhance various comments in wal.c. (check-in: 2e6a462c user: drh tags: trunk)
2010-06-23
22:00		Fix and/or improve comments in wal.c. No code changes. (check-in: ee9991be user: drh tags: trunk)
19:27		Add test case for SQLITE_FULL errors to pagerfault.test. Remove a NEVER macro in pager.c that this hits. (check-in: 3e9680c4 user: dan tags: trunk)
17:59		Include the SOURCE_ID value in the log messages output for corruption, misuse, and CANTOPEN errors. (check-in: 1727a81f user: drh tags: trunk)
17:58		Adjust the shared-memory locking range to account for the new version number values in the wal-index header. (check-in: a6dc0df3 user: drh tags: trunk)
15:55		Add a version number to the wal-index header. If SQLite encounters a version number in either the wal or wal-index files that it does not understand, the operation is abandoned and SQLITE_CANTOPEN returned. (check-in: 8d0f8a7f user: dan tags: trunk)
15:18		Fix the xCurrentTimeInt64 interface on windows. It was off by a factor of 10. (check-in: 51ef43b9 user: drh tags: trunk)

18:12		Change the name of IOCAP_SAFE_DELETE to IOCAP_UNDELETABLE_WHEN_OPEN. Have the xDeviceCharacteristics() method of the win32 VFS return this flag. (check-in: 5a5ff4e3 user: dan tags: experimental)
17:26		Add tests to pager1.test and pagerfault.test. (check-in: f5df83fd user: dan tags: experimental)
15:10		Change the unix VFS to always allocate shared-memory using a file in the same directory as the database. Otherwise, a chroot might cause different processes to use different shared memory files resulting in database corruption. (check-in: 2241788b user: drh tags: trunk)
11:30		Add tests to pager1.test and pagerfault.test. (check-in: 58c0b5bf user: dan tags: experimental)
2010-06-18
18:59		Add tests to pager1.test. (check-in: 582fca89 user: dan tags: experimental)
16:13		Rearrange some code in OP_JournalMode to avoid incorrect returns from subsequent invocations of "PRAGMA journal_mode" following an IO error. (check-in: ce0a4a9b user: dan tags: experimental)
11:10		Change the implementation of the unix implementation of xAccess() so that it returns 0 (does not exist) to an SQLITE_ACCESS_EXISTS query on a file that exists but is zero bytes in size. (check-in: 077b0e5b user: dan tags: experimental)
2010-06-17
17:05		Apply [b9b11855e8] (the alternate fix to [fc62af4523]) to the trunk. (check-in: 9a949a3a user: dan tags: trunk)
16:44		Merge trunk change [7c3a86b9c7]. (check-in: bd7bc4e0 user: dan tags: experimental)
16:44		A different fix to [fc62af4523]. When changing from journal_mode=PERSIST or TRINCATE to some other rollback mode, delete the journal file only if a RESERVED lock can be obtained on the database file first. (check-in: b9b11855 user: dan tags: experimental)
16:08		Fix the tkt-fc62af4523.test to work around non-randomness of the randomblob() function when in testing mode. (check-in: 7c3a86b9 user: drh tags: trunk)
11:36		Fix bug in journal2.test. (check-in: c1e04f1d user: dan tags: experimental)

10:24		Add test case for [fc62af4523]. (check-in: cccd32c6 user: dan tags: trunk)
06:19		Merge fix [f80c3f922a] with experimental changes. (check-in: 20133e9c user: dan tags: experimental)
02:13		Bug fix: Only trust the database size number at offset 28 if the change counter at offset 24 matches the version number counter at offset 92. This prevents corruption in the case of two applications writing to the database where one is an older version of SQLite and the other is a newer version. (check-in: f80c3f92 user: drh tags: trunk)
2010-06-16
19:48		Merge in changes up to and including the 3.6.23.1 release. (check-in: 21ca87f6 user: drh tags: apple-osx)
19:04		Experimental change: On systems where it is not possible to unlink a file while one or more processes has it open (i.e. not unix), avoid closing the journal file each time the database is unlocked and reopening it at the start of each transaction. (check-in: bede8c8a user: dan tags: experimental)
12:30		Add extra test cases to pager1.test. (check-in: ad320957 user: dan tags: trunk)

14:06		Merge in [2c5e48a485]. Merge in [2c5e48a485]. Merge in [2c5e48a485]. (check-in: 03c0f4fd user: dan tags: trunk)
13:56		Changes to the way tcl test scripts work. No changes to production code. (Closed-Leaf check-in: 2c5e48a4 user: dan tags: experimental)
12:09		Minor tweaks to the interface documentation - adding hyperlinks. (check-in: 07b2fdd1 user: drh tags: trunk)
11:21		Updates to comments and testcase() macros in wal.c. (check-in: 4d90cc0b user: drh tags: trunk)
2010-06-14
18:06		Fix an error in the walfault.test script introduced by the previous check-in. (check-in: a2b9374f user: drh tags: trunk)
18:01		Move the xShmMap method to in between xShmLock and xShmBarrier, since it seems to fit in there logically. (check-in: 58dfd83d user: drh tags: trunk)
17:09		Merge the experimental shared-memory mmap-by-chunk changes into the trunk. (check-in: f295e7ed user: drh tags: trunk)
16:16		Add the new xShmMap (formerly xShmPage) to os_win.c. (check-in: 13e7a824 user: dan tags: experimental)
14:07		Remove xShmGet/Size/Release from the sqlite3_vfs structure. Change the name of xShmPage to xShmMap. Remove some code that is now unused from os_unix.c and some of the test VFS implementations. (check-in: fc0cabc1 user: dan tags: experimental)
11:49		Update some comments in wal.c. No code changes. (check-in: 1ce9c92b user: dan tags: experimental)
11:18		Change the interface to internal function walGetHash() to make it easier to follow. (check-in: 5e8e2e97 user: dan tags: experimental)
10:30		Add the xShmPage method to the "crash" vfs in test6.c. (check-in: 1008f536 user: dan tags: experimental)
07:53		Add some fault-injection tests to improve coverage. (check-in: 37b26d12 user: dan tags: experimental)
2010-06-12
12:02		Fix some problems with handling IO errors on the experimental branch. (check-in: eade8bc2 user: dan tags: experimental)
2010-06-11
19:04		Experimental change to the xShmXXX parts of the VFS interface. (check-in: ca68472d user: dan tags: experimental)
17:01		Refactor and simplify the logic used to change journalmode. (check-in: 95cc3f6f user: drh tags: trunk)
2010-06-10
16:25		Adding original art for the new SQLite logo. (check-in: af353bd8 user: drh tags: trunk)
14:07		Add the SQLITE_TESTCTRL_PGHDRSZ verb for sqlite3_test_control() used to get the size of pcache headers for testing purposes. (check-in: 5d694f04 user: drh tags: trunk)
10:51		Update the test VFS in test_journal.c so that it implements the xCurrentTimeInt64 method. (check-in: ec3b4a7e user: drh tags: trunk)
06:53		Store the MemPage structure in memory following, instead of preceding, the page data for cached pages. This reduces the likelihood of a corrupt database page image causing SQLite to read past the end of a buffer. (check-in: 0ce42e76 user: dan tags: trunk)
01:07		Remove a condition that must always be true. Replace it with an assert(). (check-in: 7abcd54e user: drh tags: trunk)
2010-06-09
19:01		Fix test script problems causing errors in the "inmemory_journal" permutations. (check-in: ea05b7f9 user: dan tags: trunk)
16:58		When restarting (wrapping) a log file, set all unused aReadMark[] slots to READMARK_NOT_USED instead of 0. Setting them to 0 does not cause a problem, but may cause SQLite to obtain and release a few more file locks than would otherwise be necessary. (check-in: 0797b10c user: dan tags: trunk)
15:47		Fix for ticket [f973c7ac31]. (check-in: 6eb058dd user: dan tags: trunk)
14:45		Shift the meaning of aReadMark[] back so that +1 offset from mxFrame is removed. Add the new READMARK_NOT_USED value (0xffffffff) instead of zero to signal an aReadMark[] that is not in use. (check-in: c576827d user: drh tags: trunk)
11:28		Simpler fix for the race condition also fixed by [7c102c7b5f] (check-in: 3c2de820 user: dan tags: trunk)
11:02		Fix for race condition in WAL locking code. (Closed-Leaf check-in: 7c102c7b user: dan tags: mistake)
2010-06-08
15:50		Close database opened by tester.tcl when it is sourced in all.test. Because test scripts are now run in slave interpreters, this connection was not being closed by the first script run as it was previously. (check-in: b072e9f6 user: dan tags: trunk)
15:16		Changes to wal3.test to support small default cache size settings. And builds that create autovacuum databases by default. (check-in: ac4cc257 user: dan tags: trunk)
2010-06-07
19:26		In os_unix.c, call munmap() to unmap a shared-memory region prior to closing the associated file descriptor. (check-in: 95cc976f user: dan tags: trunk)
17:47		Change all.test, quick.test and permutations.test so that they use a separate interpreter for each test file. (check-in: 7c33eb5a user: dan tags: trunk)
14:28		Refactor some of the global variables and commands used by tester.tcl. (check-in: c2edf8e1 user: dan tags: trunk)
06:11		Add a couple of extra coverage tests for wal.c. (check-in: cfe60254 user: dan tags: trunk)
2010-06-05
19:18		Add further test cases for the logic in sqlite3WalBeginReadTransaction(). (check-in: a49713db user: dan tags: trunk)
18:34		Clarify the purpose of a test for a race-condition in sqlite3WalBeginReadTransaction(). (check-in: c041c6a9 user: dan tags: trunk)
18:12		Remove a condition from sqlite3WalRead() that is unreachable as of the changes to clear entries out of the wal-index hash tables on transaction or savepoint rollback. (check-in: 39420473 user: dan tags: trunk)
14:42		Mark a condition in wal.c as ALWAYS(). (check-in: 3fe0cc78 user: dan tags: trunk)
11:53		Add extra coverage test cases for wal.c. No changes to production code. (check-in: f9d4ae0e user: dan tags: trunk)
2010-06-04
18:38		Clarify an assert in sqlite3WalExclusiveMode(). (check-in: 25585069 user: dan tags: trunk)
17:16		Remove an unnecessary branch from wal.c. (check-in: 8e54786c user: dan tags: trunk)
15:59		Add an English language error message to corresponding to SQLITE_PROTOCOL. "locking protocol". (check-in: ca327e32 user: dan tags: trunk)
12:22		Add test for the code that detects an inconsistent pair of wal-index headers to wal2.test. (check-in: 157feba1 user: dan tags: trunk)
11:56		If an attempt to sync the database file as part of a checkpoint fails, do not update the shared "nBackfill" variable. Otherwise, another process could wrap the log and overwrite content before it is synced into the database. (check-in: b813233d user: dan tags: trunk)
10:37		Fix a problem where an SQLITE_BUSY in the checkpoint code was being treated as an IO error (abandoning, instead of just limiting, the checkpoint). (check-in: 02c4040c user: dan tags: trunk)
2010-06-03
19:10		Fix another problem in test_vfs.c. (check-in: df7d5989 user: dan tags: trunk)
18:20		Have test_vfs.c simulate IO errors in xShmLock. (check-in: fcbf7cf1 user: dan tags: trunk)
18:02		Performance fix for winShmClose(). (check-in: ed7774de user: drh tags: trunk)
16:58		Add extra tests for removing elements from wal-index hash tables as part of a rollback. (check-in: af3e598a user: dan tags: trunk)
12:35		Delay opening the sub-journal until SQLite actually needs to write data to it. (check-in: c43deb33 user: dan tags: trunk)
12:09		Remove global variables when compiled with SQLITE_OMIT_WSD (check-in: dd10a547 user: drh tags: trunk)
09:25		Enhancements to test_vfs.c and walfault.test. (check-in: ac0de2f3 user: dan tags: trunk)
09:17		If an error (OOM or SQLITE_FULL error) occurs while executing an SQL statement and a statement-transaction is automatically rolled back as a result, if a second error occurs during the statement rollback do a full transaction rollback instead. Otherwise the client can be left with an inconsistent cache. This can affect both WAL and rollback modes. (check-in: eb80ddc6 user: dan tags: trunk)
09:01		If a malloc fails while allocating a savepoint object at the pager level, do not try to roll that savepoint back later on. (check-in: 91cb08ff user: dan tags: trunk)
2010-06-02
20:38		When a lock fails due to an I/O error (not an SQLITE_BUSY) then the checkpoint should fail. (check-in: c6eb0a27 user: drh tags: trunk)
18:59		Fix a problem with rolling back to a savepoint opened before the writer decided to wrap the log file. (check-in: 6b4aed6a user: dan tags: trunk)
17:15		If an error occurs while writing frames to the log to commit a transaction, do not mark the pages as clean in the cache. Otherwise, the subsequent rollback does not roll them back (leaving the client to continue with a cache that makes it appear that the transaction was committed - inconsistent with the database on disk). (check-in: cb571c1b user: dan tags: trunk)
16:40		Added implementation of vfslog_time() for Windows testing. (check-in: b3109f85 user: shaneh tags: trunk)
16:39		Updated wal2.test for windows testing. (check-in: c3606f39 user: shaneh tags: trunk)
15:59		Make sure the directory used by os_unix.c for shared-memory files is always the same, regardless of individual client permissions and environment variable settings. (check-in: f97bd520 user: drh tags: trunk)
15:43		When walTryBeginRead() encounters an I/O error trying to set a lock (as opposed to SQLITE_BUSY) be sure to propagate that error back up the call stack. (check-in: aa2c2b67 user: drh tags: trunk)
14:45		Changes to make WAL more robust against SHM locking failures and OOM errors. (check-in: ebf40413 user: drh tags: trunk)
14:43		In the rowhash.test, make sure global variables are cleared prior to use. (check-in: 28efe0a4 user: drh tags: trunk)
12:58		Undo one of the "const" markers from the previous check-in because the value needs to be changable, even if it is not actually ever changed in the current implementation. (check-in: c24ac356 user: drh tags: trunk)
05:53		Add some 'const' markers to static data that is really constant. (check-in: e7073e23 user: dan tags: trunk)
2010-06-01
21:02		The shared-memory used by WAL on linux now really is shared memory in /dev/shm. On other unix flavors, the file is in a temporary directory rather than in the same directory as the database. (check-in: fc18c4aa user: drh tags: trunk)
19:15		Changes to the way faults are injected into xShmXXX VFS calls. (check-in: 716d99f3 user: dan tags: trunk)
17:46		Change the OOM and IO error test cases in walfault.test so that each test case runs both types of error simulation. (check-in: b627e153 user: dan tags: trunk)
15:44		Delay the decision to restart the log file until data is actually ready to be written to the log file (instead of at the start of a write transaction). (check-in: b1abfaaf user: dan tags: trunk)
15:24		The incremental checkpoint feature is not perfect yet, but it is working well enough to merge it into the trunk. (check-in: 1d3e569e user: drh tags: trunk)
14:30		Merge with [15abbc3416]. (Closed-Leaf check-in: f4b9003a user: dan tags: wal-incr-ckpt)
14:12		If an attempt to get a read-lock on the WAL fails with SQLITE_BUSY_RECOVER, call the busy-handler at the btree level. (check-in: ce644965 user: dan tags: wal-incr-ckpt)
13:17		Fix a bug introduced by the previous check-in but only seen if SQLITE_ENABLE_EXPENSIVE_ASSERTS is turned on. (check-in: 9c9ec899 user: drh tags: wal-incr-ckpt)
12:58		Fix an off-by-one boundary-value issue in walCleanupHash(). (check-in: f039552e user: drh tags: wal-incr-ckpt)
11:08		Do not hold the shared-memory mutex in os_unix.c if returning NULL. (check-in: 9622dd46 user: dan tags: wal-incr-ckpt)
10:44		If the checkpoint fails to obtain an exclusive lock on one of the read-lock bytes, do not consider this an error. (check-in: 9e95e357 user: dan tags: wal-incr-ckpt)
07:51		Fixes to the test cases in wal2.test. (check-in: cd5fbcbc user: dan tags: wal-incr-ckpt)
01:08		Comment edits and cleanup in wal.c. No functional code changes. (check-in: e8e666ab user: drh tags: wal-incr-ckpt)
00:28		Attempt to get the filectrl.test script running. (check-in: e46a8f2b user: drh tags: wal-incr-ckpt)
00:03		Fix os_unix.c so that it will compile and build on a Mac. (check-in: bc707c83 user: drh tags: wal-incr-ckpt)
2010-05-31
20:28		Fix issues with locking_mode=EXCLUSIVE in WAL. (check-in: 8deba0ce user: drh tags: wal-incr-ckpt)
18:24		Add an "isInit" field in the wal-index header that must be non-zero for a valid header. Use this to detect an uninitialized wal-index. (check-in: a16fde19 user: drh tags: wal-incr-ckpt)
16:56		Fix an inconsistent #ifdef in wal.c. Fix os_unix.c so that it does not allow moving an SHM lock directly exclusive to shared without going through unlocked. (check-in: 552658da user: drh tags: wal-incr-ckpt)
16:41		Avoid dropping the checkpoint lock after a recovery run as a precursor to a checkpoint operation. (check-in: cc25cfa0 user: dan tags: wal-incr-ckpt)
16:17		Zero the checkpoint header as the last step of successful WAL recovery. Avoid an unnecessary lock/unlock in WalBeginReadTransaction. (check-in: db3509c5 user: dan tags: wal-incr-ckpt)
16:10		Get the new xShmLock interface design working on os_win.c. (check-in: 149a7082 user: drh tags: wal-incr-ckpt)
14:39		Make sure WAL alway requests enough shared-memory space. (check-in: 138f1283 user: drh tags: wal-incr-ckpt)
14:28		Remove the tests that enable tracing based on the existance of the "vdbe_*" files when in SQLITE_DEBUG mode. (check-in: cdbb4e7c user: drh tags: wal-incr-ckpt)
14:18		Update another test case in wal.test. (check-in: 99fde69e user: dan tags: wal-incr-ckpt)
13:11		Change WAL test cases to account for the improved concurrency in the new checkpoint logic. (check-in: 2d6f2485 user: drh tags: wal-incr-ckpt)
12:30		Do not fail a checkpoint just because active readers prevent backfill. (check-in: 9aa4243e user: drh tags: wal-incr-ckpt)
12:15		Add WALTRACE() macros to help with debugging and analysis. (check-in: 765c3318 user: drh tags: wal-incr-ckpt)
12:02		Another minor fix to checkpoint on the WAL branch. (check-in: 853f1e3f user: dan tags: wal-incr-ckpt)

11:16		Fix some asserts and other things in the new WAL branch. (check-in: 181ceb32 user: dan tags: wal-incr-ckpt)
06:38		Changes to the way one of the WAL/OOM tests works. (check-in: 15abbc34 user: dan tags: trunk)
01:41		WAL runs but quickly deadlocks. (check-in: ace58acb user: drh tags: wal-incr-ckpt)
2010-05-30
19:55		Initial code for incremental checkpoint in WAL mode. This check-in compiles on unix and runs as long as you do not engage WAL mode. WAL mode crashes and burns. Consider this check-in a baseline implementation for getting the new capability up and running. (check-in: ef3ba7a1 user: drh tags: wal-incr-ckpt)
2010-05-29
08:40		Add tests to fkey2.test to check that ON CONFLICT clauses do not affect SQLite's behaviour when an FK constraint is violated. (check-in: e9e5b100 user: dan tags: trunk)
06:18		Minor changes to checksum related test cases. (check-in: 60c22bde user: dan tags: trunk)
2010-05-28
11:16		Add a test to walcksum.test to stress the checksum calculation. (check-in: 778d0c17 user: dan tags: trunk)
2010-05-26
17:31		Make sure the wal-index mapping is always large enough to cover the entire active area of the wal-index. (check-in: 42705bab user: drh tags: trunk)
15:06		Change the semantics of xShmGet() such that it will never increase the size of shared memory. xShmSize() must be used to grow the size of shared memory. A shared memory segment size cannot be shrunk (except by dropping it). (check-in: 72de0073 user: drh tags: trunk)
2010-05-25
15:53		Updated header comments in wal.c. No functional code changes. (check-in: 687632a6 user: drh tags: trunk)
15:23		Add a busy-handler to a test case in walthread.test to prevent errors. (check-in: d3d348aa user: dan tags: trunk)
13:49		Modify walcrash2.test so that it works with DEFAULT_AUTOVACUUM=1. (check-in: 77438882 user: dan tags: trunk)
13:40		Update header comments in wal.c to correctly describe the WAL file format. Update the locking region offsets in os_unix.c and os_win.c and add assert() statement to verify that the locking region offsets are correct. (check-in: 40030c07 user: drh tags: trunk)
10:50		If a writer exits unexpectedly in the middle of a transaction, have the following writer remove any wal-index hash-table entries left by the interrupted transaction. (check-in: ed77556a user: dan tags: trunk)
02:24		Remove unreachable code associated with WAL from the pager. (check-in: 54c1718e user: drh tags: trunk)
2010-05-24
20:27		OOM errors during an auto-checkpoint are benign. (check-in: 3d252ce5 user: drh tags: trunk)
20:24		Remove the walmode.test case from the inmemory_journal test of permutations.test. (check-in: 27ba9c21 user: drh tags: trunk)
17:00		Fix the wal2.test script so that it works in auto_vacuum mode. (check-in: 6a818afb user: drh tags: trunk)
13:57		Change the checksum used in WAL files so that each frames checksum depends on the content of the WAL header and all frame headers and content up to and including the frame to which the checksum is attached. (check-in: 8a53f12c user: dan tags: trunk)
13:28		Make sure a WAL frame of all zeros is detected as an invalid frame. (check-in: 02d99ad4 user: drh tags: trunk)
12:34		Fix up test_osinst.c to work with SQLITE_OMIT_VIRTUALTABLE. (check-in: 51fd3815 user: drh tags: trunk)
10:39		Change the WAL file format to support two kinds of checksums - one that is fast to calculate on little-endian architectures and another that is fast on big-endian architectures. A flag in the wal-header indicates which the file uses. (check-in: 65ba804d user: dan tags: trunk)
2010-05-22
08:22		Add a couple of missing methods to test_osinst.c.. (check-in: 5c9e9c06 user: dan tags: trunk)
00:55		Add several EXPENSIVE_ASSERT code blocks to validate the wal-index hash table. Fix the bugs that these code blocks fine. Rename walClearHash() to walCleanupHash() and simplify its interface. (check-in: 7aade899 user: drh tags: trunk)
2010-05-21
19:15		Fix another bug in walClearHash(). (check-in: 40f80ffe user: dan tags: trunk)
18:24		Comment out the SQLITE_FCNTL_SIZE_HINT from os_unix.c since it does not seem to provide any performance gain there. (check-in: 7d01309d user: drh tags: trunk)
16:23		Correct an off-by-one bug in the previous commit. (check-in: 75a1130d user: dan tags: trunk)
15:31		Remove entries from wal-index hash tables when a rollback or savepoint rollback occurs. (check-in: 36795c2b user: dan tags: trunk)
13:16		Fix the wal-index header read routine so that it correctly detects a zero header as being malformed and in need of a wal-index rebuild. (check-in: 1a4eb3a3 user: drh tags: trunk)
2010-05-20
23:51		Add a new xShmBarrier method to the VFS - a shared-memory fence operation. Implement the same in both unix and win32. Use it to make the WAL subsystem more robust. (check-in: 1bd011c9 user: drh tags: trunk)
21:21		Make use of the extra information in the WAL header and frame header to enhance robustness. (check-in: 9580ecb7 user: drh tags: trunk)
16:45		Convert the wal-header and frame-header to 24 bytes. Extra information in both headers is designed to enhance robustness after crashes, though the extra information is currently unused. This is a snapshot of a work in progress. (check-in: 66970643 user: drh tags: trunk)
2010-05-19
23:41		Merge WIN32 WAL support into trunk. Still some issues with locking to resolve. (check-in: 43377663 user: shaneh tags: trunk)
22:09		Cherry-pick the SQLITE_FCNTL_SIZE_HINT patch (check-in [2b7e3b4a30d6a7c4a8] and bump the version number to 3.6.23.2. (check-in: 776679af user: drh tags: branch-3.6.23)
20:30		Disable the corruptE test which SQLITE_OVERSIZE_CELL_CHECK is enabled. This is a cherrypick merge from check-in [1dc4f9fe9b83467ba]. (check-in: a40d080c user: drh tags: branch-3.6.23)
19:39		Add the SQLITE_FCNTL_SIZE_HINT to the os_win.c VFS. (check-in: 9894118d user: drh tags: trunk)
19:26		Add the SQLITE_FCNTL_SIZE_HINT operator to sqlite3_file_control() and use it to give the VFS hints about the ultimate size of a database file when the file is growing. (check-in: 2b7e3b4a user: drh tags: trunk)
19:09		Fix a bug in the new checkpoint computation. Also update the checkpoint algorithm in the test scripts to align with the new implementation. (check-in: 8b6056f2 user: drh tags: trunk)
18:08		Revise the checksumming algorithm in wal.c. More variable refactoring. (check-in: 542b90eb user: drh tags: trunk)
17:49		Refactoring some variable names in wal.c. (check-in: 1d201ff5 user: drh tags: trunk)
01:53		Add a large comment to wal.c describing the WAL and wal-index file formats. (check-in: a71a22b5 user: drh tags: trunk)
2010-05-18
23:29		Update the wal-index hash format so that hash-table space is reused following a rollback, thus preventing hash table overflows. Add assert()s to verify that hash tables do not overfill. Further refactoring of the wal-index code. (check-in: ada9a8c7 user: drh tags: trunk)
18:01		Refactoring of the WalIterator implementation. (check-in: b5b60fdc user: drh tags: trunk)
13:27		Mark the shared-memory in the WAL implementation as volatile. (check-in: 0a678790 user: drh tags: trunk)
12:56		Comment clarifications in wal.c. (check-in: a029be10 user: drh tags: trunk)

18:01		Refactoring the VFS-SHM methods used by WAL. This version compiles and runs non-WAL test cases but crashes and burns on wal.test. (check-in: 2b00152c user: drh tags: wal-refactor)
17:14		Updates to WAL support in os_win.c: pulled in latest changes from src/os_unix.c; updated tracing; misc. improvements. (check-in: 76504726 user: shaneh tags: wal-win32)
13:50		Remove the OP_Variable optimization of check-in [48b77b04935d894] since it can lead to malfunctions as described in ticket [26ff0c82d1e90]. (check-in: 7838163d user: drh tags: trunk)

2010-05-11
16:29		Have os_unix.c use the suffix "-wal-index" for wal-index files instead of "-wal-inde". (check-in: 885e854e user: dan tags: trunk)
14:00		When an attempt to change journal_mode fails due to locks, be sure to leave internal structures in a consistent state. (check-in: cf3d1e0b user: drh tags: trunk)

11:20		Enhance the OP_JournalMode opcode with an ignore-errors option and use that option the ATTACH command. (check-in: 0bdea4cf user: drh tags: trunk)
2010-05-07
20:34		When running a checkpoint while in locking_mode=EXCLUSIVE, be sure to move the wal-index lock to UNLOCK from READ prior to promoting to CHECKPOINT. (check-in: be114bdf user: drh tags: trunk)
20:02		Change the xShmOpen() method of the VFS to take the database file name as its argument, not the WAL file name. Also fix some unrelated compiler warnings. (check-in: a65c2939 user: drh tags: trunk)
18:23		Additional tweaks to API documentation. No functional code changes. (check-in: e1230782 user: drh tags: trunk)

00:28		Another attempt to fix permutations.test so that it excludes WAL tests from the journaltest permutation. (check-in: 58c40442 user: drh tags: trunk)
2010-05-06
22:21		Remove savepoint6.test from the set of tests run by journaltest since savepoint6.test uses journal_mode=WAL. (check-in: 811b45a9 user: drh tags: trunk)
21:37		The PRAGMA journal_mode=WAL; command now makes WAL the default journal mode for new databases added with ATTACH, so the behavior is consistent with the other journal modes. (check-in: c3520460 user: drh tags: trunk)
20:19		Make sure to do a clean shutdown of the library upon existing the shell in order to remove WAL files. (check-in: c1762dda user: drh tags: trunk)

18:48		Instead of transitioning to RECOVER state from CHECKPOINT when a recovery is required, perform the recovery while holding the CHECKPOINT lock. (check-in: bb0b6021 user: dan tags: trunk)
18:27		If recovery is run before a checkpoint, change back to a CHECKPOINT lock before performing the actual checkpoint. (check-in: dc98ee16 user: dan tags: trunk)
18:04		Only pass -1 as the size parameter to xShmGet when the caller does not care what size mapping is returned. Only call xShmSize when the underlying allocation (not the mapping) should be resized. (check-in: 637f51dd user: dan tags: trunk)
17:28		Fix a bug whereby an old snapshot could be checkpointed (and subsequent transactions discarded) if the last connection to disconnect from a WAL database happended to be holding an out-of-date wal-index header. (check-in: d0c0034b user: dan tags: trunk)
16:06		After throwing an error to say that one cannot change into WAL mode within a tranactions, do not then go and change into WAL mode. (check-in: 56a17dae user: drh tags: trunk)
15:56		Further coverage tests. (check-in: 98a9713e user: dan tags: trunk)

07:43		Add tests for handling errors returned by xShm VFS methods. (check-in: fbbcacb1 user: dan tags: trunk)
2010-05-05
20:00		Change the behavior of the sqlite3_wal_hook() callback. It should now return SQLITE_OK or an error code and the error code is propagated back up the stack. If a checkpoint is desired, the callback should invoke sqlite3_wal_callback() itself. (check-in: 1b14195e user: drh tags: trunk)
19:09		Further simplifications to the SHM locking logic. Remove the SQLITE_SHM_QUERY option. Unify the WRITE to READ and RECOVER to READ transitions. (check-in: e9bfa6e4 user: drh tags: trunk)
19:04		Test the handling of errors returned by the xShmXXX() APIs. (check-in: 72663123 user: dan tags: trunk)
18:46		Do not compare page sizes on source and destination of backup until transactions are started and the page sizes are locked. This is a fix to check-in [7bd44794c4]. (check-in: ec715778 user: drh tags: trunk)
18:20		Simplifications to the SHM locking implementation in os_unix.c. (check-in: 9de05bfb user: drh tags: trunk)
16:23		Prohibit backup if the destination is using WAL and has a different page size from the source. (check-in: 7bd44794 user: drh tags: trunk)
15:33		When closing a WAL database, if the exclusive lock on the database file is obtained and the database successfully checkpointed, delete the wal-index file from the file system. (check-in: 2ac5d96c user: dan tags: trunk)
04:11		Make sure the page size of the main database is fixed following a failed VACUUM attempt. Otherwise, two consecutive failed VACUUM attempts with attempted page_size changes on encrypted or WAL databases could result in database corruption. (check-in: 208e7d5d user: drh tags: trunk)
03:39		Do not attempt to modify the page_size when running VACUUM on a WAL database. (check-in: 58a1a59b user: drh tags: trunk)
00:22		Get the previous mutex fix working with SQLITE_DEBUG and with the amalgamation. (check-in: df19928f user: drh tags: trunk)
00:05		When the in single-threaded mode, the sqlite3_mutex_alloc() interface still returns a non-NULL value. The mutex doesn't do anything, but it tests non-NULL. This way, extensions (or VFSes) that use sqlite3_mutex_alloc() can tell the difference between an OOM error and mutexes being disabled. (check-in: 451fd175 user: drh tags: trunk)
2010-05-04
18:50		When sqlite3PagerPagecount() is called without any locks, always return the physical file size, not the logical file size. (check-in: 4016b422 user: drh tags: trunk)

19:17		Fix a bug in the computation of the current time for the alternative CURRENT_TIMESTAMP functions used when SQLITE_OMIT_DATETIME is defined. (check-in: e7ded46b user: drh tags: trunk)
18:51		Documentation stubs for sqlite3_wal_autocheckpoint and sqlite3_wal_checkpoint. (check-in: 31376242 user: drh tags: trunk)
18:22		Fix a bug in the xCurrentTime() method of the os_unix.c VFS. (check-in: 551df11a user: drh tags: trunk)
18:01		Add a test to simulate an OOM during log recovery to walfault.test. (check-in: 7ed85e87 user: dan tags: trunk)
17:24		Clear global variable "seconds" before use in walthread.test. (check-in: a35551a5 user: drh tags: trunk)

16:36		Update the crash-test VFS in test6.c to pass-through the shared-memory methods to the real underlying VFS. This fixes the walcrash.test script. (check-in: ea09ff37 user: drh tags: trunk)
16:30		Change the VFS definition so that all methods take a VFS object pointer as their first parameter. (check-in: 43b5b07f user: drh tags: trunk)
15:58		Have sqlite3_wal_checkpoint() handle a zero-length string in the same way as a NULL pointer. Fix "PRAGMA wal_checkpoint" so that it checkpoints all attached databases. (check-in: 7fecd21f user: dan tags: trunk)
14:32		Use VFS method xCurrentTimeInt64 instead of xCurrentTime when it is available. Provide an implementation of xCurrentTimeInt64 for os_unix.c. (check-in: ab77b3ae user: drh tags: trunk)
14:08		Merge the write-ahead-logging changes into the trunk. (check-in: de9ae443 user: drh tags: trunk)
14:05		If the sqlite3_wal_checkpoint() API is passed a NULL pointer in place of a database name, attempt to checkpoint all attached databases. (Closed-Leaf check-in: 27a5c09c user: dan tags: wal)
13:37		Make sure the mutex is held while calling sqlite3ApiExit() in sqlite3_wal_checkpoint(). Other cleanup of WAL logic. (check-in: 11a85b82 user: drh tags: wal)
12:14		Have sqlite3_wal_checkpoint() populate the database handle error message and error code (as returned by sqlite3_errmsg() and sqlite3_errcode()). (check-in: ff234cf5 user: dan tags: wal)
11:05		Add the "PRAGMA wal_autocheckpoint" command. Rename "PRAGMA checkpoint" to "PRAGMA wal_checkpoint". (check-in: 714e5947 user: dan tags: wal)
08:19		Merge two wal leaves. (check-in: 23c0e6c3 user: dan tags: wal)
08:04		Add the sqlite3_wal_checkpoint() and sqlite3_wal_autocheckpoint() APIs. (check-in: 9803196d user: dan tags: wal)
2010-05-01
20:17		Change the SHM interface so that it does not take the name of the shared object but rather the name of the WAL file and derives its own name from that. Remove the xShmDelete method from the VFS and replace it with a delete flag on xShmClose. (check-in: 94dea5f9 user: drh tags: wal)

11:19		Fix the sqlite3_mutex_alloc() interface to return NULL (not segfault) when operating in threadsafe mode. (This is a general-purpose bug fix which really ought to be ported to trunk.) (check-in: 64840a3c user: drh tags: wal)
08:30		Add test case demonstrating deadlock during recovery of very large log files. No fix yet. (check-in: 63ea318e user: dan tags: wal)
00:59		Do not allow journal_mode=WAL if the underlying VFS does not support xShmOpen. (check-in: d1fcccec user: drh tags: wal)

17:47		Change the SHM VFS logic in os_unix.c so that it does not hold an exclusive lock n the mapped memory when also holding a CHECKPOINT lock. This improves concurrency between readers and checkpointers. (check-in: 8660cda6 user: drh tags: wal)
17:28		Remove some obsolete debugging parameters. (check-in: a012aed4 user: drh tags: wal)

16:41		Fix a problem in the previous commit. Both unixShm.lockState and unixShm.readLock should be set to READ when downgrading from a WRITE to a READ lock (check-in: 90119fec user: dan tags: wal)
16:38		Fix a bug whereby upgrading from a READ_FULL to a WRITE lock, and then back to a read lock was dropping all WAL locks. (check-in: 55f5af5e user: dan tags: wal)
16:24		Reapply commits [837d82a929] and [c05e7dca17] that were accidentally overwritten. (check-in: 598de527 user: dan tags: wal)

15:49		When closing a WAL connection, attempt an exclusive lock on the database file. If the lock is obtained, checkpoint the database and delete the wal and wal-index files. (check-in: c05e7dca user: dan tags: wal)
15:24		If a reader attempts to upgrade to a writer, but is not reading the most recent database snapshot, return SQLITE_BUSY. (check-in: 837d82a9 user: dan tags: wal)
14:39		Separate the concepts of underlying storage size and mapped size in the VFS shared-memory implementation. (check-in: 4cbe49f1 user: drh tags: wal)
11:43		Add a missing walIndexUnmap() call to the checkpoint code. Change a couple of SQLITE_CANTOPEN constants to SQLITE_CANTOPEN_BKPT. (check-in: 1f9e8c5c user: dan tags: wal)
10:24		Fix an assert() in sqlite3WalRead(). (check-in: 2e7a0050 user: dan tags: wal)

00:04		Begin moving WAL-specific I/O into the VFS. This checkin contains VFS infrastructure but it is untested and is not yet hooked up to the WAL. The version number is bumped to 3.7.0 because of the VFS extension. (check-in: f5e615c2 user: drh tags: wal)
2010-04-25
20:58		Remove an unreachable branch from the function initialization logic. (check-in: 064d3ddd user: drh tags: trunk)

17:34		Do not sync any files in wal mode if "PRAGMA synchronous=off" is set. If files are synced, pass either SQLITE_SYNC_FULL or SQLITE_SYNC_NORMAL to the xSync() callback as configured by "PRAGMA fullfsync". (check-in: 0ae91b00 user: dan tags: wal)
16:10		It is possible for sqlite3.pUnlockConnection to be non-NULL when sqlite3.pBlockingConnection is NULL, as the notify1.test script demonstrates. (Closed-Leaf check-in: 95ff76ef user: drh tags: experimental)
15:45		Merge with trunk commit [3e646e3f4c]. (check-in: 43463970 user: dan tags: wal)
15:42		In synchronous=normal mode, do not sync the log after every transaction. In synchronous=full mode, sync the log and add any extra frames required to avoid blast-radius related problems after each transaction. (check-in: 9bc9b684 user: dan tags: wal)
12:53		Change sqlite3_step() so that it automatically calls sqlite3_reset() instead of returning SQLITE_MISUSE when invoked on a prepared statement that previously returned any value other than SQLITE_ROW. (check-in: 3e646e3f user: drh tags: trunk)

2010-04-14
19:01		The query planner uses non-indexable WHERE clause terms to reduce the estimated number of output rows, then uses the estimated number of output rows as a tie-breaker when choosing table order. (check-in: b87cb0c2 user: drh tags: trunk)
18:50		Add tests and fix bugs in WAL locking mechanism. (check-in: c18077f2 user: dan tags: wal)

06:18		Test that the rollback-hook is invoked if a commit-hook implementation returns non-zero (causing a rollback). Remove documentation comment that says otherwise from sqlite.h.in. (check-in: 012cf101 user: dan tags: trunk)
2010-04-12
20:54		Add e_fts3.test to the set of tests excluded from the inmemory_journal exclusion list, since it does simulated OOM errors which trigger I/O errors and SQLite is unable to recover from I/O errors without a persistent journal. (check-in: e7e7127f user: drh tags: trunk)
19:44		Recent changes cause the xSync method of the memory journal implementation to be used, so remove the assert(0). (check-in: 1f2cb940 user: drh tags: trunk)

17:08		Fix a problem where a process in exclusive mode could delete a hot-journal file without rolling it back from within sqlite3_close() or DETACH. This problem was introduced by commits from the past few days; it is not present in any release. (check-in: 51a61395 user: dan tags: trunk)
14:51		Reset the simulated device in the test harness to its default configuration whenever it is restarted. (check-in: 562d20e6 user: drh tags: trunk)
2010-04-10
17:52		Fix issues and clarify the operation of pager_playback_one_page(). A block comment in pager.c identifies 13 invariants on the pager subsystem. Ticket [9d68c883132c8]. (check-in: 09065976 user: drh tags: trunk)
2010-04-09

15:01		Fix the computation of the number of rows in a table during automatic index generation. (check-in: edeab06a user: drh tags: trunk)
14:38		Fix an integer overflow bug in the automatic index logic. The bug was detected by the testcase() macros added in the previous check-in. Also add some more testcase() macros, since this issue points up their importance. (check-in: af97b488 user: drh tags: trunk)
14:15		Add testcase() macros to the automatic index logic to insure that boundary cases are tested. (check-in: 72865478 user: drh tags: trunk)
11:35		Make sure F_OK, R_OK, and W_OK are defined in test_demovfs.c. Define them manually if they are not. This is necessary to get the module to compile on some systems. (check-in: 7c8afc32 user: drh tags: trunk)
01:16		Merge automatic index changes into the trunk. (check-in: bf7b8d86 user: drh tags: trunk)

2010-04-07
20:32		Pull over the latest changes from the trunk. (check-in: e388fe8b user: drh tags: experimental)
20:29		When rolling back a savepoint to the beginning of the transaction, make sure to initialize the database size in the btree layer correctly even if the database size field of the header is zeroed. (check-in: a3540c6a user: drh tags: trunk)
19:32		Add an interface to the SQLITE_STMTSTATUS_AUTOINDEX status information to the TCL bindings. Add some simple automatic index test cases. (check-in: 1f404412 user: drh tags: experimental)
16:54		Wrap all automatic index changes inside SQLITE_OMIT_AUTOMATIC_INDEX. Add the automatic_index PRAGMA to turn it on and off. (check-in: a811a47f user: drh tags: experimental)
14:59		Make sure that all automatic indices are covering indices. Otherwise, the table and index might be used together in a query but the table could get out of sync with the automatic index through out-of-band changes. (check-in: 23643131 user: drh tags: experimental)
14:33		Enhance comments on the SrcList object definition to better explain the operation of the SrcList.a[].colUsed field. No changes to code. (check-in: c0f67ea1 user: drh tags: experimental)

16:15		Zero the filesize-in-header word for bigfile.tcl. Remove bigfile.tcl from the journaltest permutation. (check-in: 63610c71 user: drh tags: trunk)
13:41		Do not journal the content of freelist leaf pages. This restores an optimization that was accidently undone by check-in [12f7346c13] on 2009-01-20. (check-in: b1e7a1a6 user: drh tags: trunk)
02:47		Remove a NEVER in sqlite3PagerPagecount() that can in fact be true. (check-in: 8f005337 user: drh tags: trunk)

21:13		The btree layer now tracks when a database is empty at the start of a transaction and rolls back to that state. (Closed-Leaf check-in: 01ef6c19 user: drh tags: experimental)
19:36		Fix issues with the io.test script. There is still a problem with a ROLLBACK TO not working on an initially empty database files. And much more testing is needed. (check-in: 09786e2a user: drh tags: experimental)
2010-03-27
17:12		Experimental changes that cause SQLite to use bytes 28..31 of the database header to determine the database size, rather than using the actual database size. This allows database space to be preallocated. (check-in: b844ac6f user: drh tags: experimental)
09:44		Increase the estimated cost of using a virtual table as the outer loop of a join when there exists an ORDER BY clause that is not satisfied by the virtual table. Fix for [775b39dd3c]. (check-in: 9e075e70 user: dan tags: trunk)

11:55		Attempt to suppress a warning from Borland Code Guard. (check-in: be278979 user: drh tags: trunk)
2010-03-23
18:24		More commenting and documentation enhancements in FTS3. (check-in: 892e2867 user: drh tags: trunk)
15:46		Fix up obsolete comments in FTS3 to conform to the latest nomenclature. Add new comments to better explain FTS3 operation. (check-in: 3e4a0082 user: drh tags: trunk)
15:29		Close the auxiliary database db2 at the end of the crash8.test script. (check-in: 0fbdc431 user: drh tags: trunk)
2010-03-22
23:55		Sync the database file after a rollback. This is a cherrypick merge of check-in [b21b911f23]. (Leaf check-in: 82dd61fc user: drh tags: branch-3.6.22)

17:13		After a rollback that writes or truncates the database file, sync the database file before invalidating the journal contents. Fix for [015d3820f2]. (check-in: b21b911f user: dan tags: trunk)
15:47		Disable the "init.test" test script when compiled with SQLITE_THREADSAFE=0. (check-in: ad68fa65 user: drh tags: trunk)
04:32		Change the formatting of the preprocessor macros surrounding the compileoption interface in sqlite.h.in. This is so the documentation produced by parsing this part of sqlite.h.in is formatted similarly to the docs for the deprecated interfaces (with the #ifndef visible on the webpage). (check-in: 161958d1 user: dan tags: trunk)
2010-03-19
19:23		Put an ALWAYS() around a condition in pcache.c that must always be true in the current implementation. (check-in: 88810cd0 user: drh tags: trunk)

2010-03-13
02:15		Store the database size in pages in bytes 28..31 of the header. Currently this is for forensic use only, but it might be used in the future. (check-in: 59f75bba user: drh tags: trunk)
2010-03-12
16:32		Add assert()s to mem2.c (activated by SQLITE_MEMDEBUG) which verify that memory alloctions that might have come from lookaside are always freed using a lookaside-aware free routine. (check-in: c2af2164 user: drh tags: trunk)
2010-03-10
23:13		Move the ctime.c source module near the beginning of the list of files inserted into the amalgamation so that #defines that are overridden in other modules will not effect the values returned by sqlite3_compiletime_used(). (check-in: bb591802 user: drh tags: trunk)
21:42		Add the SQLITE_DBSTATUS_CACHE_SIZE verb for sqlite3_db_status(). The highwater mark does not yet work on this verb. (check-in: 418c6d81 user: drh tags: trunk)
20:06		Remove the "experimental" markings on most interfaces that have been around for multiple releases. (check-in: d670e8bd user: drh tags: trunk)

13:12		Version 3.6.23 release candidate 3 (check-in: 747baea5 user: drh tags: trunk)
13:02		Check-in [87a6a9970b] did not completely disable FTS4. This check-in aims to finish the job. (check-in: 0259b629 user: drh tags: trunk)
12:35		Version 3.6.23 release candidate 2 (check-in: 73f4d292 user: drh tags: trunk)

2010-03-05
20:17		Make sure the dbFileVers field in the Pager object is properly initialized even if there is an I/O error while reading its content off of disk. (check-in: 81ff698f user: drh tags: trunk)
18:46		Change a condition in sqlite3VdbeMemShallowCopy() to avoid accessing an unitialized variable (doing so was not dangerous, but caused a valgrind error). (check-in: 4793c381 user: dan tags: trunk)
17:27		Fix a one byte buffer overread in fts3. (check-in: 6e3e014a user: dan tags: trunk)

13:53		Adjustments to #ifdefs so that the #include of <sys/mount.h> is not included twice, because that confuses the amalgamation builder. (check-in: 27413fc8 user: drh tags: trunk)
13:41		Adjust some #ifdefs so that the build works on Mac both with and without SQLITE_ENABLE_LOCKING_STYLE. (check-in: 0cc981f1 user: drh tags: trunk)
2010-03-04
22:36		Second thoughts: Let Tiger users set SQLITE_ENABLE_LOCKING_STYLE=0. Was: Change SQLITE_ENABLE_LOCKING_STYLE to default off, even on Macs, since older Macs (Tiger) cannot compile the latest proxy locking sources. (Closed-Leaf check-in: 1a0fa8d1 user: drh tags: mistake)
17:58		Fix for [9abd6aa831]. Do not overread a buffer used for an %q or %w conversion with a precision specifier. (check-in: 5e472896 user: dan tags: trunk)

17:06		Whoops, that shouldn't have been in the merge. Removed buggy code. (check-in: 64372800 user: icculus tags: lemon-update-2010)
17:00		Use Strsafe() instead of strdup(). Fixes Visual Studio complaining. (check-in: 89d8f98e user: icculus tags: lemon-update-2010)
16:54		Merged trunk to lemon-update-2010 branch. (check-in: 88b466ba user: icculus tags: lemon-update-2010)
16:02		Fix some extra instances of the constants addressed by [83e47ca006]. (check-in: 0354ab27 user: dan tags: trunk)
15:18		Factor out constant expressions in sqlite3GetVarint() to work around nuisance warning messages from the RVT compiler. (check-in: 83e47ca0 user: drh tags: trunk)
14:23		Modify the command line tool to disable all mutexes. The command line tool is single-threaded. (check-in: 00e56790 user: dan tags: trunk)
08:18		Fix another instance of the same warning-inducing expression in util.c. (Closed-Leaf check-in: 80c64e16 user: dan tags: mistake)
08:12		Silence a compiler warning by using a constant value instead of a constant expression that some compilers mistakenly believe causes bitshift overflow. (check-in: 587109c8 user: dan tags: mistake)
00:02		When TEMP files are in memory, also put the massive TEMP file used by the VACUUM command in memory. This is a cherry-pick merge of [9daf4e7d07] (check-in: e5342234 user: drh tags: branch-3.6.22)
2010-03-02
23:34		When TEMP files are in memory, also put the massive TEMP file used by the VACUUM command in memory. (check-in: 9daf4e7d user: drh tags: trunk)
2010-02-26
22:05		fix merge error and compiler warning (check-in: 5c0afe70 user: adam tags: apple-osx)
20:54		More double free paranoia (check-in: 62dfb44b user: adam tags: apple-osx)
16:37		Rename the sqlite_compile_option_*() SQL functions to sqlite_compileoption_*() for consistency with the C/C++ interface. (check-in: dd4962aa user: drh tags: trunk)

01:47		Start a new branch for release 3.6.22 plus limited enhancements and fixes. This first check-in includes the performance enhancements of check-ins [26cb1df735], [61a2c8d4d6], and [27dc5b1c52] (check-in: 95882598 user: drh tags: branch-3.6.22)
2010-02-24
21:44		Add testcase() macros beside each sqlite3_log() call to make sure it is tested with both logging enable and disabled. (check-in: 1168763d user: drh tags: trunk)
19:36		Changes to compile time option diags to report values for some defines. Added test cases to TCL test suite (ctime.test). (check-in: dd480f62 user: shaneh tags: trunk)
19:23		Add a sqlite3_log() call on anonymous constraint failures. Fix the output of test cases having to do with improved reprepare reporting. Fix the VACUUM command to report more helpful error messages when things go wrong. (check-in: 69a49318 user: drh tags: trunk)
18:40		Fix an incorrect ALWAYS() macro in vdbeapi.c. Fix the output of a few test cases that changed due to better error propagation out of reprepare. (check-in: a8c984c1 user: drh tags: trunk)
18:25		Remove an unused variable from rtree. (check-in: 8e60d399 user: drh tags: trunk)

2010-02-23
21:08		Fix the stmt.test test script so that it works with SQLITE_TEMP_STORE=3. (check-in: 8bf710ce user: drh tags: trunk)
20:32		Merge the compile-time option introspection interfaces into the trunk. (check-in: 9f429434 user: drh tags: trunk)
20:11		Continuing improvements to error reporting and the sqlite3_log() routine. (check-in: edea3bb7 user: drh tags: trunk)
20:08		Refactored compile time option diagnostic support to use strings identifiers instead of bitmask. (Closed-Leaf check-in: 76a0294a user: shaneh tags: compile_opts)
18:05		Fix a segfault that can occur if a malloc fails in ATTACH in shared-cache mode. (check-in: e3713737 user: dan tags: trunk)

01:01		Remove the ".genfkey" command from the shell. We've had foreign-key support in the core since 3.6.19. Anyone who still needs the simulated foreign-key triggers can always generate them with an older version of the shell. (check-in: c4401fc9 user: drh tags: trunk)
2010-02-22
23:17		Fix an assertion-fault/segfault problem that comes up when trying to VACUUM an auto-vacuumed database with a large schema. Ticket [da1151f97df244]. (check-in: 86d50ce5 user: drh tags: trunk)
19:37		Merge in the massive clean-up and ANSI-fication of Lemon carried out by Ryan Gordon. There are no functional changes to SQLite itself - Lemon still generates exactly the same parsing automaton from exactly the same grammar. (check-in: 1e8b8420 user: drh tags: trunk)
19:32		Log all error messages if logging is enabled. (check-in: a8076aed user: drh tags: trunk)
2010-02-19

19:34		Merge latest changes from the trunk into the apple-osx branch. (check-in: 4b72e39b user: drh tags: apple-osx)
17:48		Consistent use of #ifdef for SQLITE_HAS_CODEC to avoid confusion. (check-in: 34a3413a user: shaneh tags: trunk)
05:40		Removed unused variables. (check-in: ca570a02 user: icculus tags: lemon-update-2010)
04:19		Avoid using the internal printf routine for round(x,y) in the common case where y==0. (check-in: d76ad8b3 user: shaneh tags: trunk)
03:57		More rounding tests. (check-in: 3863638b user: shaneh tags: trunk)
2010-02-16
22:06		Remove duplicated assignment in realloc. (check-in: c419955d user: shaneh tags: trunk)
22:00		Added additional rounding tests. (check-in: b8ee76bc user: shaneh tags: trunk)
16:09		Removed %expect directive, on drh's advice. (check-in: b43ac330 user: icculus tags: lemon-update-2010)
16:07		Patched to compile. Accidentally removed va_list declaration. (check-in: 673d470c user: icculus tags: lemon-update-2010)
12:18		Change a C++ style comment in os_unix.c to use normal C style commenting. (check-in: 7a193309 user: dan tags: trunk)
10:59		Fix for [e9a9fde1f4]. When opening an existing rtree, determine the node size by inspecting the root node of the r-tree structure (instead of assuming it is a function of the page-size). (check-in: ebc9433f user: dan tags: trunk)
2010-02-15
18:03		Fix the ALTER TABLE RENAME command so that it converts FOREIGN KEY constraints in ATTACH-ed and in TEMP tables as well as in the main database. Ticket [13336e9c3c8c3f]. (check-in: ab197d0a user: drh tags: trunk)
16:54		When creating a trigger on a main database table when there is a TEMP table with the same name, make sure the trigger is bound to the main table. Ticket [985771e11612]. (check-in: ec914af3 user: drh tags: trunk)
15:47		Fix a compiler warning in shell.c. Updates to comments in trigger.c. (check-in: c727601e user: drh tags: trunk)

00:01		Removed the 80-char line formatting for ErrorMsg(), on dhr's suggestion. (check-in: 132ea4e5 user: icculus tags: lemon-update-2010)
2010-02-14
17:14		Make Lemon able to compile as C++ code. (check-in: 75a1060b user: icculus tags: lemon-update-2010)
05:42		Added option to not clip error output. This is useful for IDEs and other tools that benefit from full path information, so they can jump directly to the error line in the source code. (check-in: 90602030 user: icculus tags: lemon-update-2010)
05:34		Delete output files if this is a failed run. Otherwise, the fail will stop a Makefile from progressing, but if you immediately run the build again, Make will think the output files are up to date, since they are newer (albeit incomplete/incorrect). (check-in: e38c08d9 user: icculus tags: lemon-update-2010)
05:19		Added %expect directive, to consider a certain number of conflicts "correct." This has the side effect of changing the process exit code to never overflow. (check-in: d8bab8cf user: icculus tags: lemon-update-2010)
00:48		Added -T option, to specify a template filename on the command line. The default is still "lempar.c", though. (check-in: e6cbe1e5 user: icculus tags: lemon-update-2010)
2010-02-13

2009-11-04
23:02		Fix a typo on the ynVar typedef that unfortunately caused 3.6.20 to be released with a "bug" that causes excess memory usage for Expr objects.

03:01		Do not run ON UPDATE actions of a foreign key constraint unless at least one column value really does change. (check-in: 71ac8e28 user: drh tags: trunk)
02:29		Generalize the IS and IS NOT operators so that their right-hand side can be an arbitrary expression and not simple the constant NULL. They work like = and <> except that NULL values compare equal to one another an unequal to everything else. (check-in: 98853f61 user: drh tags: trunk)
2009-09-22
20:08		Factor the UMINUS and UPLUS tokens out of the parser so that the parser tables can go back to using 8-bit values instead of 16-bit values. (check-in: 3fc938c9 user: drh tags: trunk)

2009-09-14
23:47		Make sure sufficient space is allocated for at least one VDBE cursor when autoincrement is used. Ticket [a696379c1f088]. (check-in: 2b2a1ef7 user: drh tags: trunk)

2009-09-09
18:46		Trying to open a transaction in one thread and close it in another is a misuse with LinuxThreads. Doing so may cause memory and file-descriptors to be leaked. Update an assert() and some test cases to account for this. (check-in: ef99eb57 user: dan tags: trunk)
16:10		Suppress some harmless compiler warnings. (check-in: f0c72a53 user: drh tags: trunk)
15:29		Bug fix in the SQLITE_OPEN_PRIVATECACHE option added a few minutes ago. (check-in: f3a0f23b user: drh tags: trunk)
15:06		Add some tests that involve BEFORE UPDATE or BEFORE DELETE triggers messing with the row being updated or deleted. SQLite behaviour in this scenario is undefined, so the tests just check that the behaviour is relatively sane and there are no crashes. (check-in: 9a4c59a2 user: dan tags: trunk)
14:48		Update the README file to state that TCL is required in order to run the makefiles for SQLite. Ticket [7d96113ff]. (check-in: ba20091a user: drh tags: trunk)

06:14		Fix a bug in where.c that could cause SQLite to write to freed memory while compiling a query with many terms in the WHERE clause. (CVS 6952) (check-in: 8161af84 user: danielk1977 tags: trunk)
2009-07-29
06:04		Add a test to mallocI.test to show that a shared lock is correctly released if an OOM condition occurs while parsing a database schema. (CVS 6951) (check-in: 5a82620e user: danielk1977 tags: trunk)
2009-07-28
16:44		Add the experimental API sqlite3_strnicmp(). Modify fts3 so that in terms like 'column_name:token' the column_name is interpreted in a case-insenstive fashion. Ticket #3996. (CVS 6950) (check-in: 4571aa9e user: danielk1977 tags: trunk)
13:30		When flattening a SELECT query, do not discard collation sequences explicitly attached to expressions in the parent query. Fix for #3997. (CVS 6949) (check-in: b2784cf5 user: danielk1977 tags: trunk)

2009-07-27
14:15		If there is a hot-journal in the file-system, a connection with journal_mode=memory set may have to open it to effect rollback. Account for this in pager_end_transaction(). This prevents an assert from failing in the in-memory journal permutation test. (CVS 6947) (check-in: 224bc69a user: danielk1977 tags: trunk)
11:41		Do not simulate OOM conditions in the sqlite3OsXXX() calls if the underlying file is an in-memory journal file. (CVS 6946) (check-in: d4868117 user: danielk1977 tags: trunk)

2009-07-25
22:13		The noReadlock property on a pager object implies the readOnly property. Use this fact to simplify the logic in sqlite3PagerSharedLock(). (CVS 6944) (check-in: 886e665f user: drh tags: trunk)

13:42		Remove the "proc zeroblob" implementation from incrvacuum2.test. It is no longer required as of (6906) and, as #3988 points out, unreliable. (CVS 6936) (check-in: 03153831 user: danielk1977 tags: trunk)
11:46		Add files that should have gone in with the previous checkin. (CVS 6935) (check-in: 64c7afc7 user: danielk1977 tags: trunk)
11:40		Add a complex assert() that checks a pager invariant. (CVS 6934) (check-in: 2e08ad7b user: danielk1977 tags: trunk)
04:12		Add assert() statements to more tightly constrain the state of pager.c. Remove the three pager*.test scripts since they violate the constraints asserted above by modifying the state of the system in ways that it cannot be modified in a live system. (CVS 6933) (check-in: 3b6d370e user: drh tags: trunk)
00:13		Remove two more overzealous assert() statements. (CVS 6932) (check-in: 788aa9dd user: drh tags: trunk)

2009-07-21
19:25		Change getAndInitPage() (btree.c) to use only PagerAcquire(), not PagerLookup() and PagerAcquire(). (CVS 6916) (check-in: 0b41dfc0 user: danielk1977 tags: trunk)

17:11		Modify various routines inside btree.c to take a pointer to the return-code as a parameter and to no-op if the return-code storage location already contains a non-zero code. (CVS 6911) (check-in: 7dcf2a78 user: drh tags: trunk)
12:33		Use an ALWAYS() on a conditional in btmutex.c that is always true. (CVS 6910) (check-in: 609022ca user: drh tags: trunk)

2009-07-18
20:01		Code tweaks in support of full-coverage testing. (CVS 6907) (check-in: 22c6dbfd user: drh tags: trunk)
14:36		Add some code to sqlite3VdbeMemSetZeroBlob() so that it works (less efficiently) even when OMIT_INCRBLOB is defined. Ticket #3977. (CVS 6906) (check-in: f5f7259d user: danielk1977 tags: trunk)
11:52		When the asynchronous IO backend opens a file with the EXCLUSIVE flag set, make sure only a single file-descriptor is opened (not one for reading and one for writing). This change fixes #3978. (CVS 6905) (check-in: 630e669b user: danielk1977 tags: trunk)
08:30		Changes to test scripts so that (make test) works when OMIT_INCRBLOB is defined. (CVS 6904) (check-in: 1dd834a3 user: danielk1977 tags: trunk)
2009-07-17
17:25		Fix a subtle problem that can occur when a transaction is automatically rolled back, and afterwards a VM that had opened a statement transaction within the abandoned transaction is finalized. Fixes an assert() that was failing in rtree3.test. (CVS 6903) (check-in: 910df46e user: danielk1977 tags: trunk)
16:54		Return a meaningful error message if a keyword is used as an rtree table column name. Ticket #3970. (CVS 6902) (check-in: 046efe46 user: danielk1977 tags: trunk)
14:37		Skip all tests in tableapi.test if SQLITE_OMIT_GET_TABLE defined. Ticket #3975. (CVS 6901) (check-in: 0219a543 user: shane tags: trunk)

2009-07-15
18:15		Fix a potential database corruption following DROP TABLE when the pending byte page corresponds to a ptrmap page. This situation cannot happen in a real deployment - but it still needs to be fixed. (CVS 6897) (check-in: 6242db39 user: drh tags: trunk)
17:25		Simplifications to btree.c in support of structural testing. Renamed the "skip" field of the BtCursor object to "skipNext" to make it easier to search for places where it is used. (CVS 6896) (check-in: d3897235 user: drh tags: trunk)

2009-07-14
18:35		Add comments and assert() statements to show that the return value from sqlite3BtreeKeySize() and sqlite3BtreeData() usually do not matter. Ticket #3968.

2009-07-13
15:52		Remove the SQLITE_CommitBusy flag. This was an attempt to block recursion on the sqlite3_commit_hook() interface. But such recursion is explicitly disallowed, so the flag is pointless. (CVS 6889) (check-in: 1c2bfc43 user: drh tags: trunk)
13:18		Change an unreachable condition in btree.c to a NEVER(). (CVS 6888) (check-in: 9f800e11 user: danielk1977 tags: trunk)
11:22		In sqlite3PagerWrite(), do not set the PGHDR_NEED_SYNC flag on a page if an IO error occured while attempting to journal it. (CVS 6887) (check-in: b9be365d user: danielk1977 tags: trunk)

07:30		Remove a case from BtreeMovetoUnpacked() that is unreachable as of (6881). (CVS 6885) (check-in: 39ce2097 user: danielk1977 tags: trunk)
2009-07-12
02:32		Simplifications to btree.c to help facilitate coverage testing. (CVS 6884) (check-in: dfb146ef user: drh tags: trunk)
02:31		When an OOM fault occurs while moving a page for autovacuum in an in-memory database, be sure to undo the page move prior to returning the error, to avoid corrupting the in-memory database file. (CVS 6883) (check-in: d0964b93 user: drh tags: trunk)
2009-07-11

06:55		Modify the integrity-check code so that each b-tree page inspected is reinitialized while doing so, even if an initialized copy exists in the cache. This prevents an assert from failing when running integrity_check on a corrupt database. (CVS 6877) (check-in: 709576c6 user: danielk1977 tags: trunk)
05:06		Remove unreachable condition from btree.c. (CVS 6876) (check-in: 47b40fef user: danielk1977 tags: trunk)
2009-07-10

2009-07-09
13:25		Fix two faulty assert() statements btree. (It was possible for the assertions to be false given a corrupt database file as input.) (CVS 6872) (check-in: 9403f04d user: drh tags: trunk)
11:36		Remove an unused branch from btree.c. (CVS 6871) (check-in: 45efb78a user: danielk1977 tags: trunk)
08:27		In btree.c, have setSharedCacheLock() assume that the b-tree is sharable instead of checking to see if it is. The caller has already performed this check. (CVS 6870) (check-in: 3190eefd user: danielk1977 tags: trunk)
05:07		Restore (btree_set_cache_size) to test3.c. This is used on unix for the tcl "crash tests". Make some functions no longer used outside of btree.c static. (CVS 6869) (check-in: 1d96ce8c user: danielk1977 tags: trunk)
03:20		removed the test function sqlite3BtreeFlags() (test code only); (CVS 6868) (check-in: 579ba6c8 user: shane tags: trunk)

01:49		Simplifications to sqlite3BtreeInsert() and allocateSpace(). Added many testcase() macros to verify boundary conditions in btree.c. (CVS 6858) (check-in: aab82a22 user: drh tags: trunk)
2009-07-07
17:38		Improvements to corrupt database detection in defragmentPage(). (CVS 6857) (check-in: 87bbc8d6 user: drh tags: trunk)
15:47		Do not load the root-page of a b-tree table/index when opening a cursor. Instead, allow it to be loaded when the cursor is first used (in function moveToRoot()). Also move the root-page flags sanity checks that were a part of the OP_OpenRead/OpenWrite opcodes into the moveToRoot() function. (CVS 6856) (check-in: 06dcfe72 user: danielk1977 tags: trunk)
13:56		If an error occurs in PagerBegin(), call pager_end_transaction() to reset the internal state of the pager object. (CVS 6855) (check-in: ea7ed166 user: danielk1977 tags: trunk)

2009-07-06
21:54		Fix the pager so that it remembers the name of the journal for an in-memory database as an empty string. This is important when committing a multi-database transaction that includes one or more attached memory databases. (CVS 6852) (check-in: 31a5e819 user: drh tags: trunk)
19:03		Fix the backup logic so that it detects a failure to sqlite3BtreeUpdateMeta() and reports that failure back up to the top level. (CVS 6851) (check-in: 471b92f2 user: drh tags: trunk)
18:56		Make the sqlite3BtreeMoveto function static, since it is only used from within btree.c. Remove unused function lockBtreeWithRetry from btree.c. (CVS 6850) (check-in: 30d5ec62 user: danielk1977 tags: trunk)
00:44		Simplifications and comment cleanup in vdbeaux.c. (CVS 6849) (check-in: 1636e783 user: drh tags: trunk)

22:54		Remove two unused fields from the Parse structure. The TCL interface now removes leading whitespace from SQL statements before parsing them. (CVS 6846) (check-in: 983cb692 user: drh tags: trunk)
19:19		Remove unused code (that was commented out) from prepare.c. Remove an incorrect NEVER() macro. Fix the comment on schemaIsValid() to correctly describe its return behavior. (CVS 6845) (check-in: 90deb658 user: drh tags: trunk)
19:18		Cause sqlite3_exec() to return SQLITE_NOMEM if it cannot allocate memory to hold the error message for some other error. (CVS 6844) (check-in: e9849292 user: drh tags: trunk)
17:23		Remove an unused variable from the test code in test3.c. (CVS 6843) (check-in: 9e35bec9 user: drh tags: trunk)
17:09		Add a version of the Lemon parser template "lempar.c" to the src/ subfolder. This new parser template contains a couple of NEVER() macros that disable tests that are needed for general grammars but not for the specific grammar used by SQLite. SQLite builds with the modified lempar.c. (CVS 6842) (check-in: d426cc64 user: drh tags: trunk)
16:25		Simplify the way the read-uncommitted flag is handled to facilitate test coverage. (CVS 6841) (check-in: e2112d61 user: danielk1977 tags: trunk)
15:37		Make explicit the restrictions on UPDATE, DELETE, and INSERT statement syntax within triggers. Ticket #3947. (CVS 6840) (check-in: c8bf40df user: drh tags: trunk)
12:57		Test the result of pthread_create() and do not call pthread_join() if the thread creation failed. Ticket #3933. (CVS 6839) (check-in: 304c5110 user: drh tags: trunk)
2009-07-02
18:40		Fix to sqlite3AuthRead to accommodate "new" or "old" references that are used in a context where a column reference may also be used (i.e. "SELECT new.
17:21		When a b-tree transaction is committed when there are open cursors, downgrade shared-cache write-locks to read-locks instead of relinquishing all locks. Fix for #3942. (CVS 6837) (check-in: 611e704f user: danielk1977 tags: trunk)
07:47		Cause opening a transaction on a sharable b-tree module automatically obtain a read-lock on page 1. This means there is no way for sqlite3BtreeGetMeta() to fail. (CVS 6836) (check-in: e3c055f1 user: danielk1977 tags: trunk)
05:23		Fix for compilation with OMIT_AUTOVACUUM defined. Ticket #3940. (CVS 6835) (check-in: 8f0591ae user: danielk1977 tags: trunk)
2009-07-01
18:09		Change to test code and scripts allowing memsys3 to be tested using a build that has both memsys3 and memsys5 enabled. (CVS 6834) (check-in: a00aeec2 user: danielk1977 tags: trunk)
18:04		Fix a 1-byte buffer overwrite that can occur when a virtual table overloads an SQL function. (CVS 6833) (check-in: bfe336a8 user: danielk1977 tags: trunk)
16:12		Report an error if a USING or ON clause is specified following a from-list element that is not to the right of a join operator. Fix for #3846. (CVS 6832) (check-in: 29b48972 user: danielk1977 tags: trunk)
14:56		Do not ignore alias "a" in a query of the form "SELECT ... FROM (...) AS a" Fix for #3935. Also expand upon (6751) to fix some similar obscure memory leaks. (CVS 6831) (check-in: 42f9d1e5 user: danielk1977 tags: trunk)
2009-06-29
06:00		Cause incremental-blob read/write operations lock shared-cache tables in the same way as normal SQL read/writes. Add complex assert statements to make sure tehe correct shared-cache locks are held when accessing the database. Eliminate some redundant checks from btree.c. (CVS 6830) (check-in: f17ef378 user: danielk1977 tags: trunk)
2009-06-27
14:10		Version 3.6.16 (CVS 6829) (check-in: ff691a6b user: drh tags: trunk, release)
11:17		Fix an instance where sqlite3JumpHere() might be called with a negative address following an OOM fault. (CVS 6828) (check-in: 49f22e55 user: drh tags: trunk)
00:48		Fix a bug in sqlite3_realloc() - if called with a size of more than 2147483392 it returns 0 but it also releases the prior allocation. (CVS 6827) (check-in: 653df0af user: drh tags: trunk)
2009-06-26
18:35		Remove incorrect NEVER() macros from malloc.c. The allocations can be exceeded using sqlite3_malloc() and sqlite3_realloc(). (CVS 6826) (check-in: 0d345e59 user: drh tags: trunk)
16:32		Removed a few compiler warnings under MSVC. (CVS 6825) (check-in: f01a9fc3 user: shane tags: trunk)
15:14		Remove the priorNewRowid field from the sqlite3 structure. Use the last_insert_rowid as the initial value when searching for a new random rowid in the OP_NewRowid opcode. (CVS 6824) (check-in: 96729b2d user: drh tags: trunk)
14:17		Skip a couple tests requiring working 64bit int support on platforms without that support. Test code change only. (CVS 6823) (check-in: d8c8145c user: shane tags: trunk)
14:04		When sqlite3VdbeAddOp() fails due to an OOM fault, return an address of 1 rather than zero so that there appears to always be a prior instruction. This prevents a negative jump-to address computation in where.c following an OOM fault. (CVS 6822) (check-in: fe02339c user: drh tags: trunk)
12:30		Fix a test script problem in exclusive.test. (CVS 6821) (check-in: a52ef5a4 user: danielk1977 tags: trunk)
12:15		Fix the new pager.c changes so that they compile with IOTRACE defined. Fix an out-of-order variable definition in vdbeaux.c. (CVS 6820) (check-in: ac145028 user: drh tags: trunk)
10:39		Another change to test_journal.c to account for (6817). Again, only test code has changed. (CVS 6819) (check-in: 58884b6c user: danielk1977 tags: trunk)
09:01		Update test_journal.c to account for (6817). Changes to test code only. (CVS 6818) (check-in: 542ee8cc user: danielk1977 tags: trunk)
07:12		Avoid writing the 8-byte journal-header magic until the journal-header is synced. In persistent journal-mode, this prevents any old content that follows an unsynced journal-header from being interpreted as part of the rollback journal. (CVS 6817) (check-in: a5ecffcf user: danielk1977 tags: trunk)
2009-06-25
16:11		Fix a problem with a return code being ignored in insertCell(). (CVS 6816) (check-in: bb5f1c01 user: danielk1977 tags: trunk)
11:50		Get the notify2.test running again by removing an ALWAYS() that was mistakenly inserted and by taking care not to report corruption following an SQLITE_LOCKED failure during schema parsing. (CVS 6815) (check-in: 6e9140a7 user: drh tags: trunk)
09:40		Replace an "if" condition that is always true in btree.c with an assert(). (CVS 6814) (check-in: daadbd9a user: danielk1977 tags: trunk)
01:47		Improved handling of oversize string and blob errors. Other simplifications in support of full coverage testing. (CVS 6813) (check-in: 8b340766 user: drh tags: trunk)
2009-06-24
13:16		Remove an ALWAYS() macro from vdbe.c that sometimes fails on thread tests. (CVS 6812) (check-in: 52eac078 user: drh tags: trunk)
13:13		Disable the new malloc-37 test when locking_mode==exclusive. The test basically works, but sometimes reports "database is locked" instead of "out of memory" and that messes up the error reporting. (CVS 6811) (check-in: 3b8f9dec user: drh tags: trunk)
11:08		Remove a declaration of the sqlite3Assert() function that was deleted by the previous check-in. (CVS 6810) (check-in: ee20b6a2 user: drh tags: trunk)
10:26		Remove the sqlite3Assert() function. The ALWAYS() and NEVER() macros call assert() directly when compiled with SQLITE_DEBUG. (CVS 6809) (check-in: d8fc373f user: drh tags: trunk)
05:40		Simplify things by rolling the functionality of balance_shallower() into balance_nonroot(). (CVS 6808) (check-in: 11750c6a user: danielk1977 tags: trunk)
2009-06-23
20:28		Enhance autoincrement so that it works with triggers that also do autoincrement inserts, even multiple inserts into the same table. Ticket #3928 (CVS 6807) (check-in: 1330993d user: drh tags: trunk)
16:40		Remove a condition from balance_nonroot() that is always true. (CVS 6806) (check-in: c5dc80e6 user: danielk1977 tags: trunk)
15:43		Call balance_shallower() from balance_nonroot() instead of from balance(). This simplifies coverage testing a bit. (CVS 6805) (check-in: da9893e2 user: danielk1977 tags: trunk)
14:39		Update the configure script for version 3.6.16 (CVS 6804) (check-in: b614e554 user: drh tags: trunk)
14:18		Update the version number in preparation for the next release. (CVS 6803) (check-in: 207c4a02 user: drh tags: trunk)
14:15		Simplifications to vdbe.c to promote better test coverage. (CVS 6802) (check-in: 3ffc93d7 user: drh tags: trunk)
11:53		Add a test to verify that #3929 is fixed. (CVS 6801) (check-in: 16c1ae9b user: danielk1977 tags: trunk)
11:22		Fix a failing assert in btree.c. The same bug was causing a spurious SQLITE_CORRUPT return when compiled without SQLITE_DEBUG. (CVS 6800) (check-in: 47ec8749 user: danielk1977 tags: trunk)
2009-06-22
19:05		Simplifications to vdbe.c and it service routines in support of coverage testing. (CVS 6799) (check-in: 308f2e61 user: drh tags: trunk)
18:03		Remove a condition that is always true from btree.c. (CVS 6798) (check-in: 3ec8b37a user: danielk1977 tags: trunk)
12:05		Make sure sqlite3BtreeCreateTable() returns an error code if the largest rootpage field is invalid in auto_vacuum mode. Update file-format comments to describe all of the "meta" values. (CVS 6797) (check-in: bda38f5e user: drh tags: trunk)
11:10		More simplifications to vdbe.c. Remove a NEVER() from vdbe.c that is possible after all. (CVS 6796) (check-in: c8f009bd user: drh tags: trunk)
05:43		If an OOM error occurs just after obtaining a shared lock on the database file, release the lock before returning. (CVS 6795) (check-in: 971a9650 user: danielk1977 tags: trunk)
00:55		Simplifications to vdbe.c in support of coverage testing. (CVS 6794) (check-in: 16680f05 user: drh tags: trunk)
2009-06-20
18:52		When recovering from the error-state in pagerSharedLock(), do not search for a hot-journal in the file-system if the pager is configured to use an anonymous temp file as the journal. (CVS 6793) (check-in: 4b46805c user: danielk1977 tags: trunk)
11:54		If after obtaining an exclusive lock to rollback a hot-journal file it is found that the journal file has been deleted, do not return an SQLITE_BUSY error. Just downgrade the lock and continue with the current operation. This eliminates a spurious SQLITE_BUSY error caused by a race condition. (CVS 6792) (check-in: 9a066600 user: danielk1977 tags: trunk)
2009-06-19
22:50		Improved documentation on the VFS methods. Ticket #3925. (CVS 6791) (check-in: f66fc771 user: drh tags: trunk)
22:23		Do now allow a COMMIT to occur while even a single write operating is in progress. (CVS 6790) (check-in: 605520ec user: drh tags: trunk)
18:32		Fix the comment on the sqlite3PExpr() subroutine. Ticket #3924. (CVS 6789) (check-in: 4bb96db6 user: drh tags: trunk)
17:50		If a call is made to sqlite3PagerAcquire when there are no outstanding references to any pages and the pager is in the error-state, try to exit the error-state at this point. Previously this was only attempted if the pager was configured to use exclusive mode. (CVS 6788) (check-in: 62db08bc user: danielk1977 tags: trunk)
16:44		Make sure group_concat() ignores initial NULL values. (CVS 6787) (check-in: 90c3b23c user: drh tags: trunk)
14:06		Reorganize and cleanup the prepared statement object. Remove code that has been commented out for ages and is no longer relevant to anything. (CVS 6786) (check-in: 37ae5f5e user: drh tags: trunk)
02:25		Fix a possible segfault when backing up an encrypted database. (CVS 6785) (check-in: 7d8f178c user: drh tags: trunk)
00:33		Make sure the sqlite3VdbeGetOp() subroutine works even when SQLite is compiled with SQLITE_OMIT_TRACE. (CVS 6784) (check-in: 1c8ec2a6 user: drh tags: trunk)
2009-06-18
20:52		Changes to the backup functionality so that it works better with codecs. (CVS 6783) (check-in: 87d6796d user: drh tags: trunk)
17:22		Move codec management from database connections into the pager so that it will work together with shared cache. (CVS 6782) (check-in: ed08b53c user: drh tags: trunk)
11:34		Update the filefmt.test test script to conform to the previous check-in. (CVS 6781) (check-in: 40a40e81 user: drh tags: trunk)
11:29		Reduce the minimum usable page space to 480 byte from 500 bytes. (CVS 6780) (check-in: db4fb835 user: drh tags: trunk)
00:41		Remove the P3 operand from OP_IsNull since it was not being used. (CVS 6779) (check-in: 767ef1e4 user: drh tags: trunk)
2009-06-17
22:50		Avoid an assertion fault if an out-of-memory error occurs while trying to run the string-concatentation operator on a zero-blob. (This is an absurd thing to do, but even so, we still should not fault.) (CVS 6778) (check-in: 0def0b76 user: drh tags: trunk)
21:42		Fix a problem in vdbe.c that could cause a double-free of memory if the SQLITE_LIMIT_LENGTH is changed after a statement is prepared but before it is run. Also remove debugging statements from tkt3841.test. (CVS 6777) (check-in: 3d7327fd user: drh tags: trunk)
16:20		Use caution to avoid integer overflow when doing real to integer affinity operations. Ticket #3922. (CVS 6776) (check-in: 39255946 user: drh tags: trunk)
13:57		Fix a potential segfault following database corruption. Problem made visible by check-in (6772). (CVS 6775) (check-in: 69eb0ff8 user: drh tags: trunk)
13:09		Suppress some -Wextra compiler warnings from GCC. (CVS 6774) (check-in: 59ec937c user: drh tags: trunk)
11:49		Fix a bug affecting secure-delete mode introduced by (6768). (CVS 6773) (check-in: a433ca82 user: danielk1977 tags: trunk)
11:13		Fix for #3918. Also, fix the TRACE macros in balance_nonroot(). (CVS 6772) (check-in: 368e44ec user: danielk1977 tags: trunk)
01:17		A minor simplification to the tokenizer. (CVS 6771) (check-in: 18f2076a user: drh tags: trunk)
00:35		Changes to prepare.c and callback.c to promote better test coverage. (CVS 6770) (check-in: 08cca219 user: drh tags: trunk)
2009-06-16
17:49		Changes sqlite3_prepare_v2() (and related routines) so that if it fails due to a missing table and the schema is out of date, it retries once before returning SQLITE_SCHEMA. Other changes to prepare.c to facilitate coverage testing. (CVS 6769) (check-in: 256ec3c6 user: drh tags: trunk)
16:50		Changes to balance_nonroot() and BtreeDelete() to simplify delete operations and reduce stack/heap usage while balancing b-tree structures. (CVS 6768) (check-in: 092b276e user: danielk1977 tags: trunk)
14:15		Fix a link error and warning that can occur in where.c when compiling under MSVC with SQLITE_OMIT_VIRTUALTABLE defined. Ticket #3914. (CVS 6767) (check-in: 793c93be user: shane tags: trunk)
04:35		Leave out a redundant line in build.c. Ticket #3916. (CVS 6766) (check-in: d9f997ae user: danielk1977 tags: trunk)
04:31		Remove a duplicate assert from btree.c. Ticket #3915. (CVS 6765) (check-in: d89542cd user: danielk1977 tags: trunk)
2009-06-15
23:15		Additional updates to the symbol resolver and expression tree walker to facilitate test coverage. (CVS 6764) (check-in: a49c2d4b user: drh tags: trunk)
20:45		Changes to allow a clean compile with no floating-point instructions generated when SQLITE_OMIT_FLOATING_POINT is used. (CVS 6763) (check-in: 1591b832 user: drh tags: trunk)
18:32		Updates to resolve.c to facilitate full coverage testing. (CVS 6762) (check-in: c50f0f28 user: drh tags: trunk)
16:27		Fix compiler warnings with MSVC build. (CVS 6761) (check-in: e1e64307 user: shane tags: trunk)
03:28		Version 3.6.15 (CVS 6760) (check-in: aff34826 user: drh tags: trunk, release, version-3.6.15)
00:04		Update the configuration script for version 3.6.15. (CVS 6759) (check-in: 14df65dc user: drh tags: trunk)
2009-06-14
12:47		Detect database corruption and abort balance_nonroot() before the corruption causes problems. (CVS 6758) (check-in: 3448b39d user: drh tags: trunk)
2009-06-12
17:46		Change lemon so that it does not generate yytestcase() macros on destructor cases since destructors are commonly unreachable in a reasonable grammar. For the reduce-rule switch, gather all no-ops into the "default:" case. (CVS 6757) (check-in: caebfe82 user: drh tags: trunk)
15:47		The previous check-in ((6755)) put in more yytestcase() macros than are called for. This check-in addresses that problem. (CVS 6756) (check-in: a5b182f9 user: drh tags: trunk)
13:53		The lemon parser generator now inserts yytestcase() macros on reduce action and on each destructor, to verify that all have been executed. yytestcase() is a no-op by default but can be set to something more useful inside of %include. (CVS 6755) (check-in: fe9c9177 user: drh tags: trunk)
12:50		In lemon: omit unused entries from the end of the yyFallback array. (CVS 6754) (check-in: 9cfbe2ba user: drh tags: trunk)
12:04		Enable the SQLITE_LIMIT_FUNCTION_ARG limiter. (CVS 6753) (check-in: a17e3317 user: drh tags: trunk)
11:42		Remove a C++-ism from the code. Ticket #3912. (CVS 6752) (check-in: bc729bc3 user: drh tags: trunk)
03:47		An additional memory leak in the parser fixed. Ticket #3911. (CVS 6751) (check-in: 6197b492 user: drh tags: trunk)
03:27		Make sure nested queries with USING clauses do not leak memory. Preliminary fix for ticket #3911. (CVS 6750) (check-in: bd341a10 user: drh tags: trunk)
02:27		Modifications to the parser to eliminate unreachable code. (CVS 6749) (check-in: 457e0b24 user: drh tags: trunk)
2009-06-11
17:32		Honor the SQLITE_OPEN_READONLY flag even on a :memory: or temporary database, even though such a database is pointless. Ticket #3908. (CVS 6748) (check-in: 73ba841a user: drh tags: trunk)
17:04		Add an ALWAYS() to a conditional in where.c. (CVS 6747) (check-in: 1fdb3e1e user: drh tags: trunk)
00:47		Changes to reenable codec operation and to handle memory allocation failures within a codec. (CVS 6746) (check-in: 43a6ca98 user: drh tags: trunk)
2009-06-10
19:33		Do not let the reverse_unordered_selects pragma force the use of an index that would not otherwise be used. Ticket #3904. Also: remove an test which is always true. (CVS 6745) (check-in: 78a391dc user: drh tags: trunk)
11:07		Remove a NEVER() that can sometimes occur on an OOM error. (CVS 6744) (check-in: c27f23bb user: drh tags: trunk)
09:11		Minor tweak to balance_quick() to save a few instructions. (CVS 6743) (check-in: 9ace9959 user: danielk1977 tags: trunk)
2009-06-09
19:53		Remove the actual checks that verify that memory pools (such as set up using SQLITE_CONFIG_HEAP) are 8-byte aligned. But document that 8-byte alignment is required. (CVS 6742) (check-in: e9b55ccc user: drh tags: trunk)
18:58		Fix compiler warnings with MSVC build. (CVS 6741) (check-in: 0bd84e73 user: shane tags: trunk)
18:14		Avoid a false failure report in the test scripts caused by the vdbe stack "compression" script. (CVS 6740) (check-in: 9d332989 user: shane tags: trunk)
18:02		Require that the buffer specified by SQLITE_CONFIG_HEAP be 8-byte aligned. (CVS 6739) (check-in: 18b78068 user: drh tags: trunk)
18:01		Changes to tokenize.c to facilitate full coverage testing. (CVS 6738) (check-in: 5e8c48cf user: drh tags: trunk)
15:25		Change savepoint4.test to limit database growth. Otherwise the test can take a very long time to run, depending on the prng. (CVS 6737) (check-in: ed1d4f47 user: danielk1977 tags: trunk)
14:27		Modify mkkeywordhash.c so that it puts the original text of each token in a comment beside the "testcase()" macros. (CVS 6736) (check-in: a7d0817c user: drh tags: trunk)
13:42		Enable cell overflow checking in sqlite3BtreeInitPage() using the compile-time option SQLITE_ENABLE_OVERSIZE_CELL_CHECK. Change the tests so that they recognize different error messages depending on the setting of this macro. (CVS 6735) (check-in: 56bff6eb user: drh tags: trunk)
11:34		Avoid calling fillInCell() to create an internal node intkey cell from balance_nonroot(). A single putVarint() does the same thing more quickly. (CVS 6734) (check-in: 2e5d42ae user: danielk1977 tags: trunk)
10:37		Only do the cell overread checks in sqlite3BtreeInitPage if SQLITE_OVERREAD_CHECK is defined at compile-time. (CVS 6733) (check-in: 49f544eb user: drh tags: trunk)
09:41		Do not clear the MemPage.nFree variable when insertCell() adds an overflow cell to a page. Not doing this means balance_quick() can avoid a call to sqlite3BtreeInitPage(). (CVS 6732) (check-in: 8f1c1f61 user: danielk1977 tags: trunk)
2009-06-08
19:44		Additional comments to clarify the operation of the LIKE optimizer in where.c. (CVS 6731) (check-in: cc9c1217 user: drh tags: trunk)
17:11		Clarification of the operation of the OR-term optimizer in where.c. (CVS 6730) (check-in: 6b42dc3d user: drh tags: trunk)
14:49		Change the btree balance code so that it does not call balance_nonroot() recursively. (CVS 6729) (check-in: 7863db90 user: danielk1977 tags: trunk)

16:08		Fix an error in the malloc.test test script causing a small buffer overread. (CVS 6725) (check-in: 4d129bee user: danielk1977 tags: trunk)
15:17		Make sure the result of sqlite3VdbeGetOp() is not used as an array following an OOM error, since after (6691) it might be a single-entry dummy opcode. (CVS 6724) (check-in: 127b1398 user: drh tags: trunk)
14:13		When building in debug mode with gcc, force the nullMem variable in function columnMem() to be aligned to an 8-byte boundary. Otherwise an assert() statement may fail. (CVS 6723) (check-in: 3fd6c72d user: danielk1977 tags: trunk)
2009-06-05
18:44		Detect when database corruption causes an attemp to set the pointer map value for a pointer map page and report the corruption. (CVS 6722) (check-in: 3ae4880b user: drh tags: trunk)
17:09		Remove leftover "breakpoint" commands from test scripts. Also remove blank lines at the end of scripts. (CVS 6721) (check-in: 1fef16ec user: drh tags: trunk)
16:46		Do not cast an unsigned int into an int for comparison. (CVS 6720) (check-in: 302ab855 user: drh tags: trunk)
14:17		Take care that a corrupt variable-length integer does not cause 32-bit integer overflow when parsing a record format, nor cause excessively large memory allocations. (CVS 6719) (check-in: 38b20327 user: drh tags: trunk)
2009-06-04
19:06		Earlier detection of freelist corruption in the page allocation routines. (CVS 6718) (check-in: e557c8e5 user: drh tags: trunk)

Also update the corrupt7.test result vectors for a couple of cases where the error report on database corruption changed due to earlier detection. (CVS 6717) (check-in: 1335e444 user: drh tags: trunk)
16:14		If the root page of a btree is empty and is also not a leaf page and the page is not page 1, then report database corruption. (CVS 6716) (check-in: 52b02ca5 user: drh tags: trunk)

2009-06-03
21:04		Change the pcache1.c implementation so that the "header" occurs at the end of page buffer, not at the beginning. This insures that the 20 bytes immediately following the page buffer are mapped if a read of the page buffer overruns due to a malformed cell. (CVS 6711) (check-in: c54de1f5 user: drh tags: trunk)
17:26		Add corruptD.test, a container for testing the "cell overflow" problem. Also shuffle a small amount of code in BtreeInitPage() to check that the page header pointer to the start of the cell offset array is set to a sane value. (CVS 6710) (check-in: 7fa5d3cb user: danielk1977 tags: trunk)
11:25		Define a set of constants to use as the "index" argument to sqlite3BtreeGetMeta and UpdateMeta. This makes some parts of the code easier to follow. (CVS 6709) (check-in: 6dbf4eca user: danielk1977 tags: trunk)

15:21		Add the vdbe-compress.tcl script which automatically refactors the sqlite3VdbeExec() routine to use less stack space. Use this script when constructing the amalgamation. (CVS 6704) (check-in: 7f433918 user: drh tags: trunk)
2009-06-01

18:18		Malloc for space to hold the Parse object in sqlite3_prepare() and friends. Or, if compiled with SQLITE_USE_ALLOCA, obtain space for the object from alloca(). (CVS 6702) (check-in: c7c0c58e user: drh tags: trunk)
17:10		Added assert to verify winMutex system is inited before "static" mutexes are used. (CVS 6701) (check-in: b126013b user: shane tags: trunk)

2009-05-29
19:00		Enhance the sqlite3VdbeGetOp() routine so that it always returns a pointer to VdbeOp, even following an OOM fault. This simplifies error handling in callers. Cleanup to the column cache logic and the expr.c source module. (CVS 6691) (check-in: ede06dac user: drh tags: trunk)
14:39		Refinements in expression handling logic that have resulted from recent structural testing. (CVS 6690) (check-in: bd89f2c2 user: drh tags: trunk)
11:57		Still more refinements to the hasHotJournal() fix of ticket #3883. (CVS 6689) (check-in: 726b425e user: drh tags: trunk)
10:55		The hasHotJournal() fix of check-in (6687) causes some minor problems in various alternative operating modes, such as locking_mode=EXCLUSIVE. This additional patch attempts to fix those concerns. Ticket #3883. (CVS 6688) (check-in: a2ba61d9 user: drh tags: trunk)
00:30		Modify the hasHotJournal() routine to return a false-positive if it is unable to open the journal file to check its header due to a race condition. Processing downstream of hasHotJournal() already knows how to deal with false-positives. Ticket #3883. (CVS 6687) (check-in: d6b5d8e1 user: drh tags: trunk)
2009-05-28

11:05		Workaround the need for internal API sqlite3BtreeCursorDb(). It was only being used for an assert() statement, which can be done differently. (CVS 6683) (check-in: 5904af6e user: danielk1977 tags: trunk)
01:00		Additional refinements to Expr handling. Restore compression of trigger expressions. Change Expr.zToken to Expr.u.zToken and added Expr.u.iValue. Remove an unnecessary ExprDup from CHECK constraint processing. And so forth. (CVS 6682) (check-in: 4ac2bdfb user: drh tags: trunk)

11:08		In the previous, the upper bound on the number of function arguments is 127, not 255. Ticket #3876 (CVS 6673) (check-in: 4fe4c5fa user: drh tags: trunk)
11:07		Correct and clarify the documentation on the third parameter to sqlite3_create_function(). (CVS 6672) (check-in: 6b7929ed user: drh tags: trunk)
2009-05-22
15:43		Do not transform a WHERE clause of the form "a = ? OR a = ?" to "a IN (?, ?)" if "a" is a column of a virtual table. Ticket #3871. (CVS 6671) (check-in: fad88e71 user: danielk1977 tags: trunk)
11:12		Add an assert() to pcache1.c to double-check that page cache buffer memory is never allocated if pcache1 is not enabled. Ticket #3872 (CVS 6670) (check-in: 93369d91 user: drh tags: trunk)
11:10		Additional changes to pcache1 to prevent the page buffer memory from being configured if pcache1 is not enabled. Ticket #3872. (CVS 6669) (check-in: 5153ad19 user: drh tags: trunk)

20:53		Rework the logic that generates a schema for tables created using "CREATE TABLE ... AS SELECT ...". Instead of trying to copy the raw datatype string from the right-hand side, just make the type one of TEXT, INT, REAL, NUM, or nothing. This is much simpler than trying to parse and quote datatype strings. Other minor implifications to build.c are bundled with this change. (CVS 6626) (check-in: 33cf8359 user: drh tags: trunk)
18:22		Enhance the parser to allow nested parentheses in the module argument of a CREATE VIRTUAL TABLE statement. (CVS 6625) (check-in: 93772bd7 user: drh tags: trunk)

2009-05-04
20:20		Make sure va_arg() does not occur on the same line as any "if" statement or "?" operator. (CVS 6602) (check-in: 3543be6e user: drh tags: trunk)
19:01		Avoid parsing cells that fit entirely on the b-tree page when searching a b-tree index. (CVS 6601) (check-in: 77a82395 user: danielk1977 tags: trunk)

01:58		Work toward cleaning up the authorizer interface. Work is on-going. This is an incremental check-in. (CVS 6598) (check-in: 694662f7 user: drh tags: trunk)
2009-05-03
20:23		Changes to facility full coverage testing of util.c. (CVS 6597) (check-in: a6122990 user: drh tags: trunk)

15:46		Simplifications to the uniqueness constraint failure error message generation code. (CVS 6595) (check-in: 8f3cac76 user: drh tags: trunk)
13:29		Remove the aFKey hash table, which was not being used. Simplify the FKey object. Simplify the hash.c module since the copyKey parameter formerly used only by aFKey is now no longer required. (CVS 6594) (check-in: 80c43a35 user: drh tags: trunk)
12:02		Reduce the size of an integer literal in rowhash.tcl so that the test is able to run with the default TCL installation on Mac OS 10.5. (CVS 6593) (check-in: 2229acce user: drh tags: trunk)
10:03		When a cursor points at the last entry of an intkey btree after an insert, leave it there (instead of moving it to the tree root node). This speeds up statements of the form "INSERT INTO ... SELECT ..." that use auto-generated rowids. (CVS 6592) (check-in: 9950c0a7 user: danielk1977 tags: trunk)
07:36		Do not reset the cursor before seeking it in sqlite3BtreeInsert(). This speeds up INSERT operations that use auto-generated rowid values. (CVS 6591) (check-in: 20c4acc2 user: danielk1977 tags: trunk)
00:28		When checking indices for xfer compatibility, compare collating sequences by string, not by pointer. (CVS 6590) (check-in: 7d2b80c7 user: drh tags: trunk)
2009-05-01
21:13		Record within the Token structure itself whether or not the token has been dequoted. This steals one bit from the length of a token and thus limits the size of tokens to 1GiB. (CVS 6589) (check-in: 12bcb03d user: drh tags: trunk)
15:17		Fix an error message that is generated if the number of columns do not match on an INSERT into a virtual table with hidden columns. (CVS 6588) (check-in: 795b453c user: drh tags: trunk)
13:16		Update PRAGMA integrity_check so that it treats SQLITE_IOERR_NOMEM errors from underlying components the same as SQLITE_NOMEM errors. (CVS 6587) (check-in: 26444f2a user: drh tags: trunk)
10:55		Change lock2.test so that it does not enter a busy loop if the child process exists unexpectedly. (CVS 6586) (check-in: 164a7f5a user: danielk1977 tags: trunk)

15:59		Documentation updates for sqlite3_set_authorizer(). No changes to code. (CVS 6579) (check-in: 41f39c31 user: drh tags: trunk)
13:30		Disallow attaching the same database multiple times to the same db connection in shared cache mode, since doing so leads to deadlock. (CVS 6578) (check-in: 715f14f1 user: drh tags: trunk)
12:25		Fix apparent typo on exclusive.test in the (6575) check-in. (CVS 6577) (check-in: 95d22405 user: drh tags: trunk)
12:25		Changes sqlite3TempInMemory() to take a const parameter. (CVS 6576) (check-in: aa29a14c user: drh tags: trunk)
09:10		When SQLite is configured to use in-memory temp files (either by setting SQLITE_TEMP_STORE during compilation or using the temp_store pragma at run time), store statement/savepoint journals in memory also. Ticket #3825. (CVS 6575) (check-in: 38f8c5a1 user: danielk1977 tags: trunk)
05:40		Fix a memory leak introduced in the previous check-in. (CVS 6574) (check-in: f082bf36 user: drh tags: trunk)
05:19		Take care not to leave a zombie attached database if the attachment fails due to an encoding mismatch. Update attach logic to always use dynamically allocated error message strings. (CVS 6573) (check-in: a6cb4002 user: drh tags: trunk)
01:22		Remove always-true tests from attach.c. In btree.c, always test the return from sqlite3PagerSetPagesize() since it might return SQLITE_NOMEM. (CVS 6572) (check-in: 8bf60b24 user: drh tags: trunk)
00:11		Remove an always-true test from delete.c. Move the sqlite3OpenTable() routine from delete.c to insert.c since it is not used in delete.c. (CVS 6571) (check-in: 71756dc8 user: drh tags: trunk)
2009-04-29
18:12		Fixed compile for MSVC; removed compiler warnings; changes for NDEBUG build; minor code tweaks. (CVS 6570) (check-in: e98b1242 user: shane tags: trunk)

11:50		Fix a case in where.c where a crash can follow a malloc failure. Also modify test code in test8.c to check a return code that was being dropped (causing a test in vtab_err.test to fail). (CVS 6567) (check-in: 9664e2b6 user: danielk1977 tags: trunk)
11:31		Add a version of cellSizePtr() that is faster than using sqlite3BtreeParseCellPtr(). This speeds up balance_nonroot(). (CVS 6566) (check-in: e8f7f7b7 user: danielk1977 tags: trunk)
06:27		Simplify a conditional expression in btree.c. (CVS 6565) (check-in: fc3a5ac2 user: danielk1977 tags: trunk)
2009-04-28
18:00		Fix an out-of-order test number in blob.test. Cosmetic change. No changes to code. Ticket #3830. (CVS 6564) (check-in: e8556542 user: drh tags: trunk)
17:33		Fix asserts in hash.c so that zero-length symbols can be used. (CVS 6563) (check-in: fe9f00aa user: drh tags: trunk)
16:37		When testing with TEMP_STORE=3 and the test pcache, only run 20 iterations in trans.test. Otherwise the test pcache runs out of memory. (CVS 6562) (check-in: 0799b729 user: danielk1977 tags: trunk)
16:35		Remove an unused function declaration from hash.h. (CVS 6561) (check-in: fcf70bb8 user: drh tags: trunk)
15:48		Further adjustment to rowhash.test to account for rowid collisions. (CVS 6560) (check-in: 94a23f99 user: danielk1977 tags: trunk)
15:43		Simplifications to the symbol table implementation in hash.c. For very small symbol tables (less than 10 entries) a simple linked list is used instead of a hash table. Number of hash table buckets is limited to prevent large allocations. (CVS 6559) (check-in: 5c737835 user: drh tags: trunk)
15:35		Have sqlite3_create_collation() return MISUSE if passed an encoding value other than SQLITE_UTF8, SQLITE_UTF16LE, SQLITE_UTF16BE, SQLITE_UTF16 or SQLITE_UTF16_ALIGNED. (CVS 6558) (check-in: 7975b6f2 user: danielk1977 tags: trunk)

12:08		Another fix to the same assert as in (6555). It can also fail after a malloc error. (CVS 6556) (check-in: e096f90a user: danielk1977 tags: trunk)
11:10		Fix an assert that could fail after a parse error in expr.c. (CVS 6555) (check-in: a37d1174 user: danielk1977 tags: trunk)
05:27		Avoid changing the pager journal-mode once a write-transaction is open, even if no database pages have been modified. (CVS 6554) (check-in: ad8aba3e user: danielk1977 tags: trunk)
04:51		Add test cases for sqlite3_complete with an EXPLAIN QUERY PLAN on a CREATE TRIGGER statement. Ticket #3828. (CVS 6553) (check-in: 6b86b40e user: drh tags: trunk)
04:47		Make sure sqlite3_open16() always zeros the db return pointer if SQLite initialization fails. (CVS 6552) (check-in: 057c7d17 user: drh tags: trunk)
04:46		Enhance sqlite3_complete() so that it understands EXPLAIN QUERY PLAN. Ticket #3828. Testing is done in TH3. (CVS 6551) (check-in: 3ac1b15f user: drh tags: trunk)
2009-04-27
18:46		Bring the documenation and implementation of sqlite3_collation_needed() into agreement. Use a more efficient implementation of sqlite3ErrStr(). sqlite3_result_error_code() now calls sqlite3ErrStr() if no prior error string was set. (CVS 6550) (check-in: cb9af829 user: drh tags: trunk)
2009-04-25
08:39		Tests for the new asynchronous IO API. (CVS 6549) (check-in: 11b2564e user: danielk1977 tags: trunk)
2009-04-24
20:32		Add another test case for the "x IS NULL" uniqueness problem of ticket #3824. No changes to code. This just double-checks that everything is working now. (CVS 6548) (check-in: 3ceae357 user: drh tags: trunk)
18:06		Dequote the "from" table in a FOREIGN KEY definition (affects the output of "pragma foreign_key_list). Fix for #3800. (CVS 6547) (check-in: 600482d1 user: danielk1977 tags: trunk)
15:46		Get rid of the special RowSet processing in where.c and move that into clients. Added the WHERE_DUPLICATES_OK option to eliminate an unnecessary RowSet during DELETE with a WHERE clause containing ORs. (CVS 6546) (check-in: 98606bee user: drh tags: trunk)
14:51		Make sure that the optimizer realizes that an "x IS NULL" contraint does not necessarily give a single-row result even on a UNIQUE index. Ticket #3824. (CVS 6545) (check-in: 207335fd user: drh tags: trunk)
10:13		Make selecting the asynchronous IO file-locking mode a runtime operation. Still untested. (CVS 6544) (check-in: 577277e8 user: danielk1977 tags: trunk)
09:27		Improve comments and documentation of the asynchronous IO VFS module. (CVS 6543) (check-in: 92bc6be2 user: danielk1977 tags: trunk)
2009-04-23
19:08		os_win.c, winOpen(), changed to handle the SQLITE_OPEN_EXCLUSIVE flag and sharing modes in the same manner as os_unix.c. Ticket #3821. (CVS 6542) (check-in: 18fef3fc user: shane tags: trunk)
18:42		Updated misc. test scripts for Windows testing with gcc/cygwin; (CVS 6541) (check-in: 1e2c7159 user: shane tags: trunk)

14:58		Move the asynchronous IO code from src/test_async.c to ext/async/. Refactor it to be a standalone module and to support windows. (CVS 6539) (check-in: e71fb0fb user: danielk1977 tags: trunk)
13:22		Rework the column-cache mechanism to be more robust (and more correct). The column-alias cache is currently disabled, (CVS 6538) (check-in: dd4d67a6 user: drh tags: trunk)
2009-04-22
17:15		Eliminate the OP_VRowid opcode. The regular OP_Rowid now work for both regular and virtual tables. (CVS 6537) (check-in: ecbef450 user: drh tags: trunk)
15:32		Change the OP_Rowid opcode so that a deferred OP_Seek is pending, it simply pulls the rowid from the deferred seek target and does not actually move the cursor or do a seek. Other where.c cleanups. (CVS 6536) (check-in: 1c508a99 user: drh tags: trunk)
02:15		Remove the rowhash object from the code. Rowset now fills its role. (CVS 6535) (check-in: e963bed0 user: drh tags: trunk)
00:47		Extend the Rowset object to contain all the capabilities of Rowhash in addition to its legacy capabilities. Use Rowset to replace Rowhash. In addition to requiring less code, This removes the 2^32 result row limitation, uses less memory, and gives better bounds on worst-case performance. The Rowhash implementation has yet to be removed. (CVS 6534) (check-in: b101cf70 user: drh tags: trunk)
2009-04-21
18:20		Move RowHashBlock.nUsed to RowHash.nUsed. Fix a typo in a comment in test_async.c. (CVS 6533) (check-in: 799d31d9 user: danielk1977 tags: trunk)
17:23		Fix a segfault that followed a malloc failure introduced by (6527). (CVS 6532) (check-in: 08e71b11 user: danielk1977 tags: trunk)
17:13		Adjust the rowhash.test module so that it recovers gracefully in the rare event of a rowid collision. (CVS 6531) (check-in: 72e16809 user: drh tags: trunk)
16:15		Allocate the initial RowHash object using lookaside. (CVS 6530) (check-in: 9b30ab71 user: drh tags: trunk)

2009-04-20
17:43		Change the journal_mode pragma so that it always returns the current journal mode, even on a failed attempt to change the journal mode. Allow the journal mode to be changed as long as there is not a pending transaction. Ticket #3811. (CVS 6526) (check-in: 419e320a user: drh tags: trunk)
13:32		Add new tests to show that journal_mode=OFF works with locking_mode=EXCLUSIVE as long as the journal_mode is set prior to the first transaction. Ticket #3811. (CVS 6525) (check-in: e62ac26f user: drh tags: trunk)
12:31		Clarify the documentation to make it clear that sqlite3_interrupt() does not effect new SQL statements that are started after the running statement count reaches zero. Ticket #3815. (CVS 6524) (check-in: 3182e8bf user: drh tags: trunk)
12:07		Do not use deprecated interfaces internally when compiling with SQLITE_OMIT_DEPRECATED. Ticket #3813. (CVS 6523) (check-in: 7f17956d user: drh tags: trunk)
11:34		Speed improvements by avoiding unnecessary calls to fstat() and ftruncate(). (CVS 6522) (check-in: 5b7e3a41 user: drh tags: trunk)
2009-04-19

2009-04-17
16:54		Revise the implementation of sqlite3_initialize() slightly in order to make it more easily testable. The functionality should be unchanged. (CVS 6519) (check-in: bb1a390a user: drh tags: trunk)
15:18		Get the behavior of SQLITE_HAVE_ISNAN right. It was reversed in check-in (6517). Ticket #3809. (CVS 6518) (check-in: 97c6ea23 user: drh tags: trunk)
11:57		Add the SQLITE_HAVE_ISNAN compile-time option which, if present, causes SQLite to use the math library isnan() function rather than its own homebrew implementation of isnan(). (CVS 6517) (check-in: 54d23521 user: drh tags: trunk)
11:56		Check-in (6514) did not completely remove the obsolete test, resulting in a segfault. This check-in finishes the job. Ticket #3802. (CVS 6516) (check-in: c29b37ea user: drh tags: trunk)
2009-04-16
17:45		Add NEVER and ALWAYS tags to conditionals in analyze.c that always false or true. (CVS 6515) (check-in: fbbc80ea user: drh tags: trunk)

00:24		In a 3-fold compound SELECT make sure early code generation of the SELECTs to the right do not dereference non-existant columns in SELECTs on the left. (CVS 6511) (check-in: 414f3408 user: drh tags: trunk)
2009-04-15
15:16		Fix the group_concat() function so that it inserts the separator string even if the initial content strings are empty. Ticket #3806. (CVS 6510) (check-in: b83fbf15 user: drh tags: trunk)

13:07		Disable the temptrigger.test test script when shared cache is disabled. Ticket #3801. (CVS 6507) (check-in: feedbce8 user: drh tags: trunk)
2009-04-14

12:58		Change the sqlite3_bind_value() implementation to use a default branch on the type switch so that there are no untested jumps in the switch. (CVS 6505) (check-in: d0a8bd6a user: drh tags: trunk)
12:43		Reimplement the sqlite3_bind_value() interface so that it works when the value being bound comes from a different database connection. (CVS 6504) (check-in: 3db0c798 user: drh tags: trunk)
2009-04-13
14:43		Enhancements to virtual table documentation. Comment changes only. No changes to code. (CVS 6503) (check-in: b0b2b283 user: drh tags: trunk)

2009-04-11
19:09		Fix malloc5.test so it work on both 64-bit and 32-bit systems. The ::tcl_platform(wordSize) variable has to be used to adjust some memory sizes. (CVS 6499) (check-in: ea20f78e user: drh tags: trunk)
16:27		Fix an obscure problem with recovery from I/O errors while rolling back. (CVS 6498) (check-in: 24ff4861 user: drh tags: trunk)

14:46		Allocate a little extra scratch space for the memsubsys1 tests. The extra space is needed in some configurations. (CVS 6495) (check-in: 54844192 user: drh tags: trunk)
11:38		Increase the hard upper bound on the number of pcache pages in test_pcache when the test harness is compiled for in-memory temp tables. Some of the test cases need to extra memory to avoid unplanned out of memory errors. (CVS 6494) (check-in: 7f2d6a0b user: drh tags: trunk)
10:25		Replace invocation of (really_finish_test) from async.test with (finish_test). Otherwise a tcl exception may be thrown when running permutations. (CVS 6493) (check-in: e6465e9d user: danielk1977 tags: trunk)
09:51		In sqlite3PagerMovepage(), avoid holding a reference to page number X when calling sqlite3PcacheRekey() to move another page to page number X. (CVS 6492) (check-in: 4447c94f user: danielk1977 tags: trunk)
2009-04-10
23:11		Remove more unused branches from vdbeapi.c. (CVS 6491) (check-in: 447e9595 user: drh tags: trunk)
20:55		In the async test, make sure procedures do not get renamed over top of one another. (CVS 6490) (check-in: b6430cc4 user: drh tags: trunk)
20:32		Remove unused branches from the vdbeapi.c module. (CVS 6489) (check-in: 7ae0fc7e user: drh tags: trunk)
18:41		Increase the error tolerance when verifying the approximate size of a pseudo-random database in backup_ioerr.test. Otherwise the test could fail depending on the PRNG seed. (CVS 6488) (check-in: deda5ab3 user: danielk1977 tags: trunk)
18:32		Do not run io.test as part of the inmemory_journal permutation. io.test uses the tcl API to test for journal files in the file-system (which of course never exist when running with in-memory journals). (CVS 6487) (check-in: 493f03bd user: danielk1977 tags: trunk)
18:21		Re-enable the alt_pcache tests in permutations.test so that they run automatically during a full regression. Fix async.test so that it works with the permutation.test pcacheNN test modules. (CVS 6486) (check-in: 310192cc user: drh tags: trunk)
15:42		Fix MSVC compiler warning in vdbeaux.c. (CVS 6485) (check-in: d619465e user: shane tags: trunk)
15:38		Disable the select1-15 tests when locking_mode is EXCLUSIVE. Ticket #3771. (CVS 6484) (check-in: 88cefbb4 user: drh tags: trunk)
15:02		Changes to jrnlmode.test to account for in-memory temp databases. (CVS 6483) (check-in: c31d4359 user: danielk1977 tags: trunk)
14:28		Simplifications and additional comments on the sqlite3_get_table() implementation. Changes to facilitate full branch test coverage. (CVS 6482) (check-in: 57e3e6b3 user: drh tags: trunk)
12:55		Changes to ensure that when running in shared-cache mode with a non-threadsafe build, the correct busy-handler callback is always invoked. (CVS 6481) (check-in: 683e4bd7 user: danielk1977 tags: trunk)
09:47		Always set BtShared.db when entering the BtShared mutex. Ticket #3793. (CVS 6480) (check-in: ed6620ba user: danielk1977 tags: trunk)
00:56		Force 8-byte alignment of sqlite3_value objects in the sqlite3VdbeUnpackRecord() primitive. Ticket #3777. (CVS 6479) (check-in: 2cc68272 user: drh tags: trunk)
2009-04-09
21:02		Increase the version number to 3.6.13 in preparation for the next release. (CVS 6478) (check-in: 9a09a474 user: drh tags: trunk)
14:27		Provide dummy DWORD arguments to output parameters of GetDiskFreeSpace(A|W), NULL causes access violations on Windows NT 4.0 (CVS 6477) (check-in: 5350a658 user: chw tags: trunk)
14:02		Remove misuse detection from the deprecated sqlite3_transfer_bindings() interface. The code was hard to test and was simply taking up space. (CVS 6476) (check-in: 4cd82910 user: drh tags: trunk)
01:23		Enhance sqlite3_shutdown() so that it automatically invokes sqlite3_reset_auto_extension(). This is a harmless no-op if applications are already calling sqlite3_reset_auto_extension() prior to sqlite3_shutdown(). And it prevents possible memory corruption if they do not. So it works either way. Most of the changes are to the test cases. (CVS 6475) (check-in: 0c41f7cf user: drh tags: trunk)
2009-04-08
23:05		Simplify the implementation of the columnName() function in vdbeapi.c. This is a code cleanup only - no behavior changes. (CVS 6474) (check-in: 0628f586 user: drh tags: trunk)
23:04		Add an assert() to the implementation of count(*) that checks the correct operation of the sqlite3_aggregate_count() function. (CVS 6473) (check-in: f322be38 user: drh tags: trunk)
16:10		Reconfigure the default case for the printf switch in order to improve branch coverage. (CVS 6472) (check-in: 3cc79162 user: drh tags: trunk)
15:45		Remove a pair unnecessary conditions from printf.c. The "db" parameter is now required for sqlite3MPrintf(). (CVS 6471) (check-in: 6fe8b5d7 user: drh tags: trunk)
13:51		Minor refactoring of the expression-compaction logic for clarity of presentation. New comments added. The EXPRDUP_DISTINCTSPAN flag is removed as obsolete. (CVS 6470) (check-in: 44ded2ea user: drh tags: trunk)
12:21		Do not attempt to walk a TokenOnly or SpanOnly expression tree node. Ticket #3791. (CVS 6469) (check-in: 8362d883 user: drh tags: trunk)
11:49		Add a comment to printf.c - no changes to code. (CVS 6468) (check-in: ee5a4a0e user: drh tags: trunk)
2009-04-07
22:06		Fix the sqlite3_unlock_notify() interface so that when the callback is NULL it simply cancels any outstanding callbacks. (CVS 6467) (check-in: 9ccfcb76 user: drh tags: trunk)
22:05		Remove two unused tests from the integrity_check pragma logic. (CVS 6466) (check-in: 22999d31 user: drh tags: trunk)
14:38		Fix an incorrect assert in btree.c. (CVS 6465) (check-in: 2c1f5983 user: danielk1977 tags: trunk)

13:48		Only enable WHERE-tracing when both TEST and DEBUG are enabled. (CVS 6463) (check-in: 55b93649 user: drh tags: trunk)
11:21		Change "... myfunction() { ... }" to "... myfunction(void) { ... }" in a few pla ces. Ticket #3783. (CVS 6462) (check-in: 6f79e6ae user: danielk1977 tags: trunk)
09:16		Have OP_IdxRowid handle the case where the index entry it is reading from is deleted. (CVS 6461) (check-in: cdad29b5 user: danielk1977 tags: trunk)
05:35		Compile fixes and improvements for vxwork: fixed deadlock in semClose, detect if fcntl is usable, fall back to named semaphores if not. (CVS 6460) (check-in: efd0682b user: chw tags: trunk)
00:49		Remove an unused test for EXPLAIN-mode in the PRAGMA processing. (CVS 6459) (check-in: 909683b3 user: drh tags: trunk)
00:43		Always enable WHERE-tracing on a test build. Oops - accidentally included a debugging change to pragma.c in this check-in. The real fix for the pragma problem is in the following checking. (CVS 6458) (check-in: 567cf90b user: drh tags: trunk)
00:35		It is OK for a unix file descriptor to be zero. It just can't be negative. Adjust an assert accordingly. Ticket #3781. (CVS 6457) (check-in: 47aa7eb0 user: drh tags: trunk)
2009-04-06
17:50		Test cases and minor code changes to increase coverage of btree.c. (CVS 6456) (check-in: def3a016 user: danielk1977 tags: trunk)
15:55		Updates and clarification to the documentation of the sqlite3_temp_directory global variable. No changes to code. (CVS 6455) (check-in: aea99c57 user: drh tags: trunk)
14:16		Allow "default" to be a keyword used by PRAGMA statements. (CVS 6454) (check-in: ed99d2d9 user: drh tags: trunk)
12:26		Make sure the reverse_unordered_selects pragma works even on unindexed tables that are queried without a WHERE clause (CVS 6453) (check-in: d8c6b28a user: drh tags: trunk)
11:11		Check-in (6450) introduced the possibility of calling memset() with a negative 3rd argument. This fixes that bug. Ticket #3777. (CVS 6452) (check-in: 8ca612c4 user: drh tags: trunk)
2009-04-05
15:18		Fix a segfault in Lemon that occurs if the input grammar does not define a type for tokens. This does not effect SQLite since the SQLite grammar does define a type for tokens. (CVS 6451) (check-in: 4424aee9 user: drh tags: trunk)
12:22		Additional code to make sure and to assert that memory allocations have 8-byte alignment. Ticket #3777. (CVS 6450) (check-in: 208382e0 user: drh tags: trunk)
2009-04-04
16:02		Allow the journal_size_limit to be larger than 2147483647 bytes. (CVS 6449) (check-in: 81931259 user: drh tags: trunk)
15:53		Allow the journal_mode for in-memory databases to be either OFF or MEMORY, not just MEMORY. (CVS 6448) (check-in: 11c77f4c user: drh tags: trunk)
14:04		Clarify the meanings of the SQLITE_SYNC_NORMAL and SQLITE_SYNC_FULL flags passed into the xSync method of the VFS. Comment changes only - no changes to code. (CVS 6447) (check-in: c47aeb37 user: drh tags: trunk)
2009-04-03
12:12		Remove a blank line in sqlite.h.in that was preventing the SQLITE_LOCKED_SHAREDCACHE constant appears in the automatically-generated documentation. Ticket #3775. (CVS 6446) (check-in: 65f9d3b9 user: drh tags: trunk)
12:04		Use integer rather than floating point compuations in converting from julian day number to unix-time to avoid round-off errors on Borland compilers. Ticket #3769. (CVS 6445) (check-in: c26f97bd user: drh tags: trunk)
01:43		Fix the PRAGMA parser so that it can accept negative numbers in parentheses, like the syntax diagrams say it should be able to. (CVS 6444) (check-in: 286e8317 user: drh tags: trunk)
2009-04-02
20:27		Make sure count(*) works on the sqlite_master table of an empty database. Ticket #3774. (CVS 6443) (check-in: e0c1a780 user: drh tags: trunk)
20:16		Make sure the VACUUM statement locks down the page_size and auto_vacuum modes after it runs. Otherwise, pragmas might change these settings on a populated database, resulting in problems. (CVS 6442) (check-in: 85e6a474 user: drh tags: trunk)
18:32		Fix the sqlite3_prepare() family of interfaces so that they zero the *ppStmt value even on an SQLITE_MISUSE return. Make it clear in the documentation that the ppStmt parameter cannot be zero. (CVS 6441) (check-in: 23bf9f26 user: drh tags: trunk)
18:28		Fix a problem causing the BtShared.isPending flag to be cleared to early. Also coverage improvements for btree.c. (CVS 6440) (check-in: 8f142344 user: danielk1977 tags: trunk)
17:23		Ensure the required VerifyCookie/Transaction/TableLock opcodes are added for "x IN (SELECT c FROM t)" expressions. Ticket #3771. (CVS 6439) (check-in: 058a2f20 user: danielk1977 tags: trunk)
17:22		Fix a couple of harmless nuisance warnings. (CVS 6438) (check-in: 53dac0a4 user: drh tags: trunk)
16:59		Disable the query flattening optimization when the subquery is a compound query with an ORDER BY clause. Ticket #3773 shows why that combination does not work. (CVS 6437) (check-in: 23f90d50 user: drh tags: trunk)
14:05		Change the way that the random() SQL function prevents the maximum negative integer so that it is testable. (CVS 6436) (check-in: 995f2b9b user: drh tags: trunk)
13:36		Use ALWAYS and NEVER macros on unchangeable conditions within func.c. (CVS 6435) (check-in: eb65e64e user: drh tags: trunk)
10:16		In the built-in SQL function implementations, improve some comments, fix an off-by-one error in detecting over-size strings, and add testcase() macros to verify that boundary values have been tested. (CVS 6434) (check-in: 868a487f user: drh tags: trunk)
09:07		Enforce the run-time sqlite3_limit() length limit on zeroblob(), not just the compile-time SQLITE_MAX_LENGTH limit. (CVS 6433) (check-in: a04f9e79 user: drh tags: trunk)
2009-04-01
23:49		Increase test coverage of bitvec.c slightly. Fix the line length on a comment in bitvec.c. (CVS 6432) (check-in: ca3aa3ba user: drh tags: trunk)
23:09		Mark untestable branches of memjournal.c as such. Reduce the size of a single block allocation to a power of two. Reenable the inmemory_journal permutation test. (CVS 6431) (check-in: 05c182a5 user: drh tags: trunk)
20:44		Fix the strftime() function so that the %s format can handle dates outside of the range of 1901 to 2038. Ticket #3769. (CVS 6430) (check-in: a95b843a user: drh tags: trunk)

18:40		Fix a bug in the sqlite3Utf16ByteLen() function so that it computes the correct length even for strings that contain surrogate pairs. Ticket #3766. (CVS 6427) (check-in: 766bb7e5 user: drh tags: trunk)
18:25		Test that two database connections that use different VFS implementations may not share a cache. (CVS 6426) (check-in: 3a92c956 user: danielk1977 tags: trunk)
18:03		Remove the unused SQLITE_Vtab flag. (CVS 6425) (check-in: fdd78962 user: danielk1977 tags: trunk)
17:13		In pageReinit() in btree.c, only reinitialize a page if there are one or more references to it, not including the transient reference held by pager.c. This was always the intent. (CVS 6424) (check-in: 0c5a7d11 user: danielk1977 tags: trunk)
16:33		Remove dead code from the UTF conversion routines. Fix a bug in sqlite3_prepare16_v2() in which an out-of-memory error fails to set the statement return pointer to NULL. (CVS 6423) (check-in: 94e2f815 user: drh tags: trunk)
16:25		Remove an unreachable branch from allocateSpace() in btree.c. Add comments and asserts to the same function. (CVS 6422) (check-in: f8e15a54 user: danielk1977 tags: trunk)
09:41		Add some assert() statements to querySharedCacheTableLock(). (CVS 6421) (check-in: 3e3b5e86 user: danielk1977 tags: trunk)
07:38		add a sanity check to make sure the configure script and VERSION file are always in sync (CVS 6420) (check-in: 1b9da6d7 user: vapier tags: trunk)

01:32		Remove two unused lines from pcache.c. (CVS 6415) (check-in: d5cab05c user: drh tags: trunk)
00:50		Added a test case for ticket #3672. (CVS 6414) (check-in: 7f40576d user: drh tags: trunk)
2009-03-30

12:56		Avoid calls to newer TCL interfaces in the test logic. This helps the TCL test harness compile without warnings and link when using older versions of the TCL library. (CVS 6409) (check-in: 1ad17637 user: drh tags: trunk)
12:42		Avoid all use of the "LL" suffix for long-long integer literals. Ticket #3759. (CVS 6408) (check-in: 7ef36935 user: drh tags: trunk)
11:59		Display a warning that the notify2-3 test sometimes fails on single-core machines. (CVS 6407) (check-in: ab7c718d user: drh tags: trunk)
07:39		Another change related to (6401) and (6402): When an attempt to unlock a file fails in os_unix.c, close all files held open waiting for the unlock event anyway. This prevents a file-descriptor leak when testing IO errors. (CVS 6406) (check-in: 50fbcdea user: danielk1977 tags: trunk)
2009-03-29
15:12		Add a comment to the doubleToInt64() routine that explains why returning minInt is in fact correct when it seems like maxInt should be returned. (CVS 6405) (check-in: 7f3be360 user: drh tags: trunk)
00:15		Turn off the debugging macros in where.c - left on by mistake in the previous check-in. (CVS 6404) (check-in: b601a575 user: drh tags: trunk)

23:23		In the unix-backend, when simulating an I/O error on an unlock operation, still mark the connection as unlocked to avoid a future assert(). (CVS 6401) (check-in: fb35cff8 user: drh tags: trunk)
18:56		The test_async.c module must pass an unchanging filename to the underlying VFS. (CVS 6400) (check-in: d1eeee21 user: drh tags: trunk)
17:21		Fix thread related problems in test modules test_async.c and test_journal.c. (CVS 6399) (check-in: 45df27a2 user: danielk1977 tags: trunk)

10:54		The fix in (6395) was not correct. Fix #3756 a different way. (CVS 6397) (check-in: 9278f7b1 user: danielk1977 tags: trunk)
07:03		Fix a couple of test script bugs. No changes to SQLite code. (CVS 6396) (check-in: c9fa329f user: danielk1977 tags: trunk)
06:59		Fix readDbPage() so that if an SQLITE_IOERR_SHORT_READ is encountered, the page content is zeroed. Ticket #3756. (CVS 6395) (check-in: 647e3b15 user: danielk1977 tags: trunk)
2009-03-27
15:26		When "PRAGMA case_sensitive_like" is invoked, override all existing "LIKE" functions, including UTF-16 versions. (CVS 6394) (check-in: 1c6521e5 user: danielk1977 tags: trunk)
12:44		Fix another compiler warning in the test logic of tclsqlite.c. (CVS 6393) (check-in: 47ffc4dc user: drh tags: trunk)

2009-03-26
17:13		Check that the first byte of a potentially hot journal file is non-zero before beginning hot-journal rollback. Fix for #3751 and #3745. (CVS 6390) (check-in: 80241a05 user: danielk1977 tags: trunk)
14:48		Prevent the tcl test suite from throwing an exception when a threadsafe SQLite is linked against a non-threadsafe Tcl for testing. Print a warning instead. Ticket #3753. (CVS 6389) (check-in: a22e7c81 user: danielk1977 tags: trunk)
12:20		Added new tests of the scratch memory allocator for increased test coverage. (CVS 6388) (check-in: e99e28ef user: drh tags: trunk)
11:49		Ensure that the test vfs in test_journal.c zeroes sqlite3_file.pMethods if an xOpen() call fails. Similar problem to that fixed by #6384. This was a problem with test code, not SQLite itself. (CVS 6387) (check-in: 45ae830d user: danielk1977 tags: trunk)
2009-03-25
16:51		Remove an unused parameter from sqlite3DequoteExpr. Fix another unrelated and harmless compiler warning. (CVS 6386) (check-in: 8589b0fc user: drh tags: trunk)
15:43		Fix a problem preventing sqlite3_extended_errcode() from working correctly. (CVS 6385) (check-in: de469c46 user: danielk1977 tags: trunk)
14:24		When a VFS.xOpen fails, make sure the pMethods pointer is zeroed on the sqlite3_file object so that subsequent xClose() operations against that same file handler are no-ops. Bug in the test_async.c module only - not in the core library. Ticket #3744. (CVS 6384) (check-in: c32b4541 user: drh tags: trunk)
01:06		Use fdatasync() only on linux, unless -Dfdatasync=fdatasync is set at compilation time. (CVS 6383) (check-in: cbf2ca4c user: drh tags: trunk)
2009-03-24
18:42		Change OS_UNIX to SQLITE_OS_UNIX in test_thread.c. Modify notify2.test to print out its timings in addition to reporting success or failure. (CVS 6382) (check-in: 940d72d2 user: drh tags: trunk)
17:43		Get the OOM tester in async2.test working again. (CVS 6381) (check-in: f398a2d1 user: drh tags: trunk)
16:55		Adjust the lock.test and lock3.test scripts so that they work with the asynchronous VFS. (CVS 6380) (check-in: 40df926b user: drh tags: trunk)
16:27		Include sqliteInt.h in test_async.c so that the asynchronous VFS tests will run even if SQLITE_OS_UNIX is not explicitly defined. (CVS 6379) (check-in: 29b0d6a3 user: drh tags: trunk)
15:31		New assert()s added to verify that the Expr.token value is used correctly. Ticket #3743. (CVS 6378) (check-in: cf3d84ab user: drh tags: trunk)
15:08		Changes to insure that lookaside memory allocations are never used to hold schema content. Ticket #3743. (CVS 6377) (check-in: ea74d8dc user: drh tags: trunk)
04:46		Add a comment to prepare.c explaining why the lookaside buffer is disabled before sqlite3_exec() is called to parse a schema statement. No code changes. (CVS 6376) (check-in: 8ca6a665 user: danielk1977 tags: trunk)
2009-03-23
21:37		Clarify the meaning of a comment. No changes to code. (CVS 6375) (check-in: 7c2df04b user: drh tags: trunk)
17:49		Add asserts to make sure that database connection locks are held when accessing the lookaside memory allocation buffers. No defects were found. (CVS 6374) (check-in: 8a9f3e66 user: drh tags: trunk)
17:11		Fix an obscure race condition that can occur when multiple threads, shared cache and DDL statements are combined. Enhance notify2.test to test this scenario. (CVS 6373) (check-in: 92ec5975 user: danielk1977 tags: trunk)
04:33		Use the ROUND8() macro to round an integer up to the nearest multiple of 8 and ROUNDDOWN8() macro to round down to the nearest multiple of 8. This is a cosmetic change. (CVS 6372) (check-in: db1d4d2f user: danielk1977 tags: trunk)
02:34		Fix compiler warning in MSVC. (CVS 6371) (check-in: 83a4d5b3 user: shane tags: trunk)
2009-03-22

2009-03-21
16:19		Update comments in build.c to conform to the latest implementation. (CVS 6369) (check-in: a915e8e0 user: drh tags: trunk)
14:56		Rig the unix backend to use fdatasync() by default, without having to set the HAVE_FDATASYNC macro. Systems that do not support fdatasync() can be compiled using -Dfdatasync=fsync. (CVS 6368) (check-in: a3315627 user: drh tags: trunk)
14:41		On unix, always use fdatasync() instead of fsync() when available, even if the file size changes, since (we are told) fdatasync() will automatically flush the inode when the file size changes. (CVS 6367) (check-in: 0d6b11bc user: drh tags: trunk)
2009-03-20
15:16		Add a test to try to hit the race-condition fixed by (6363). (CVS 6366) (check-in: 4310411f user: danielk1977 tags: trunk)

13:15		Rename the unused MEM2 static mutex to OPEN and reuse it to serialize access to the sqlite3BtreeOpen() routine to prevent a race condition on detection of sharable caches. Ticket #3735. (CVS 6363) (check-in: 19fa5a29 user: drh tags: trunk)
10:24		Fix a problem in thread005.test cause errors on osx. (CVS 6362) (check-in: 56e6fca1 user: danielk1977 tags: trunk)
09:09		Fix a problem in loadext.test causing an error on OSX. This is not a real problem, just a case of the test script expecting a slightly different error message than the one returned. (CVS 6361) (check-in: 18680989 user: danielk1977 tags: trunk)
2009-03-19
18:51		Fix a couple of fairly obscure cases where an assert() could fail following a malloc failure. (CVS 6360) (check-in: cc0d9256 user: danielk1977 tags: trunk)
07:58		Change sqlite3_step() to return SQLITE_LOCKED if a statement cannot be re-compiled due to locks on the shared-cache schema. Also add a blocking wrapper of sqlite3_prepare_v2() to the test code. (CVS 6359) (check-in: e8be1af9 user: danielk1977 tags: trunk)
2009-03-18
18:43		Fix a crash that could occur when creating an index in shared-cache mode with lookaside enabled. (CVS 6358) (check-in: 097737e3 user: danielk1977 tags: trunk)

2009-03-17
22:33		Move the rowid cache out of VdbeCursor and into BtCursor. When multiple BtCursors are open on the same table, set their rowid cache all at the same time. Ticket #3731. (CVS 6354) (check-in: 18978583 user: drh tags: trunk)
17:49		Fix a problem that could cause a crash when a shared-cache schema contains column default values. (CVS 6353) (check-in: afadddc3 user: danielk1977 tags: trunk)

10:59		Remove surplus white space from shell.c. Use strlen30() instead of strlen(). (CVS 6346) (check-in: 324a1aff user: drh tags: trunk)
2009-03-14
08:37		Fix for #3719. When synthesizing a CREATE TABLE statement as as result of a "CREATE TABLE AS", quote the column type names unless they are simple identifiers or simple identifiers followed by one or two dimensions (e.g. "VARCHAR(10)").

2009-03-05
14:59		Begin purging dirty pages from the cache once 90% of the cache is dirty (insteadof waiting until it is 100% dirty). This improves performance in some circumstances by effectively reserving 10% of the configured page-cache for frequently reused read-only pages. (CVS 6341) (check-in: 823fe7f5 user: danielk1977 tags: trunk)
14:53		Comment out a recently added assert statement that is failing. (CVS 6340) (check-in: d0b2015f user: danielk1977 tags: trunk)

14:24		Fix the SQLITE_ENABLE_UPDATE_DELETE_LIMIT option for the new Expr compression logic of check-in (6305). Bug discovered during regression testing. (CVS 6333) (check-in: 91969eda user: drh tags: trunk)
01:22		Fix a bug in the GROUP BY alias name resolution. The bug was by check-in (6305). Discovered by regression test on 64-bit linux. Test cases added so that the problems is detected on 32-bit systems. (CVS 6332) (check-in: fa000850 user: drh tags: trunk)
2009-03-01
22:29		Suppress some compiler warnings (where possible). Ticket #3696. (CVS 6331) (check-in: a2373e54 user: drh tags: trunk)

2009-02-28
10:47		Instead of linking temporary triggers on non-temporary tables into the Table.pTrigger list, search the temp schema for them on demand. Fix for #3688. (CVS 6329) (check-in: 3befe1ef user: danielk1977 tags: trunk)
2009-02-26
07:15		In sqlite3_table_column_metadata(), hold the mutex on all attached BtShared objects while accessing schema objects. Fix for #3679. (CVS 6328) (check-in: d197afd6 user: danielk1977 tags: trunk)
2009-02-25
19:07		Move the new genfkey shell command out from within #ifdef _WIN32_ (CVS 6327) (check-in: 48ee0e47 user: drh tags: trunk)
15:43		Remove genfkey.c. Change genfkey.README to talk about the new shell dot-command, not the old standalone genfkey program. (CVS 6326) (check-in: 36d69966 user: danielk1977 tags: trunk)
15:22		Add the 'genfkey' functionality to the sqlite3 shell. Accessed using a new dot-command - ".genfkey". (CVS 6325) (check-in: 0a59fb28 user: danielk1977 tags: trunk)

10:14		Reverse commit (6315) for now. (CVS 6317) (check-in: 0e7c369c user: danielk1977 tags: trunk)
10:01		Optimize queries of the form "SELECT count(*) FROM <tbl>" by adding a sqlite3BtreeCount() interface to the btree layer. (CVS 6316) (check-in: d4aa6593 user: danielk1977 tags: trunk)
2009-02-23
17:33		Scan an index instead of a table for "SELECT count(*) FROM <tbl>" queries. Because an index is usually smaller than a table on disk, this saves some IO. (CVS 6315) (check-in: 294ba6f7 user: danielk1977 tags: trunk)
16:52		Add the reverse_unordered_selects pragma. (CVS 6314) (check-in: bc078e00 user: drh tags: trunk)
14:42		Ensure the return value of sqlite3_errmsg16() is aligned on a 2-byte boundary. Ticket #3665. (CVS 6313) (check-in: 9b8acf83 user: danielk1977 tags: trunk)
2009-02-21
22:38		The sqlite3.def file is automatically generated and is not suppose to be part of the source code repository. So it is hereby removed. Ticket #3671. (CVS 6312) (check-in: 5dcda154 user: drh tags: trunk)
2009-02-20
22:27		unbreak Autoconf-based build procedure by added missing backup.lo to the list of library objects (CVS 6311) (check-in: 94945801 user: rse tags: trunk)
10:58		Instead of using SetNumColumns, specify the number of columns in a table or index using the P4 argument. (CVS 6310) (check-in: e43ed649 user: danielk1977 tags: trunk)
03:55		Add a count parameter to the OP_Variable opcode and use it to simplify prepared statements that copy consecutive unnamed parameters into consecutive registers (a common case). (CVS 6309) (check-in: 48b77b04 user: drh tags: trunk)
03:02		Add the OP_HaltIfNull opcode and use it to simplify prepared statements for INSERTs and UPDATEs of tables with NOT NULL columns. (CVS 6308) (check-in: feccad8d user: drh tags: trunk)
01:28		Reuse space left-over opcode space at the end of the VDBE opcode array to store memory cells, VDBE cursors, and other content needed by the VDBE. This reduces the memory required by a prepared statement. (CVS 6307) (check-in: 58a18092 user: drh tags: trunk)
2009-02-19
20:50		Remove code in malloc.c that was already commented out using #if 0. (CVS 6306) (check-in: e1ad757e user: drh tags: trunk)
14:39		Changes to reduce the heap space consumed by triggers, views and tables in the in-memory representation of the schema. Also to reduce the space used by prepared statements slightly. (CVS 6305) (check-in: d9f6ffbc user: danielk1977 tags: trunk)
2009-02-18
20:31		Make sure the auto_vacuum=INCREMENTAL setting is preserved across a VACUUM. Ticket #3663. (CVS 6304) (check-in: ded04f12 user: drh tags: trunk)
18:37		Move the text of C-API requirements out of the sqlite.h.in source file and into separate files in the "docsrc" CM system. Comment changes only - no changes to code. (CVS 6303) (check-in: 419eb48b user: drh tags: trunk)
12:25		Fix the amalgamation builder to mark sqlite3PagerBackupPtr as private. Ticket #3662. (CVS 6302) (check-in: fb281950 user: drh tags: trunk)
04:35		run autoconf so the updated version is in the configure script (CVS 6301) (check-in: edbb3586 user: vapier tags: trunk)
04:34		break libsqlite3.la install step out so the tcl install step can depend on it as well (CVS 6300) (check-in: 0998c554 user: vapier tags: trunk)
00:00		Version 3.6.11 (CVS 6299) (check-in: 6abd630c user: drh tags: trunk, release)
2009-02-17
18:37		Add tests to double-check that nothing within SQLite ever tries to allocate amounts of memory that are close to the maximum signed integer, leading to an integer overflow within malloc(). This is not currently a problem. The extra tests just insure it never becomes a problem. (CVS 6298) (check-in: f6ba7bb9 user: drh tags: trunk)
17:56		Initialize an uninitialized buffer to silence a valgrind warning during a VACUUM operation. (CVS 6297) (check-in: 8c61968b user: danielk1977 tags: trunk)
16:29		Allow sqlite3_shutdown() to be called by a process before sqlite3_initialize() is. Prior to this commit such a call could segfault. (CVS 6296) (check-in: 79431c58 user: danielk1977 tags: trunk)
16:17		Make sure result variables are initialized or unused following a failure of the xFullPathname VFS interface. Problem detected by valgrind. (CVS 6295) (check-in: 59a47551 user: drh tags: trunk)
2009-02-16
17:55		Changes to remove some compiler warnings from MSVC. (CVS 6294) (check-in: 68f15442 user: shane tags: trunk)

2009-02-13
16:59		Make sure OOM errors in the ANALYSIS loader get reported back out to high-level layers. Strange behavior can result otherwise. (CVS 6292) (check-in: 88a6355c user: drh tags: trunk)
03:43		Correctly handle attempts to add a UNIQUE or PRIMARY KEY column using the ALTER TABLE statement. Ticket #3651. (CVS 6291) (check-in: dd179ff2 user: drh tags: trunk)
2009-02-12
17:07		Add additional cross-references from API documentation to other documents. Comment changes only; no changes to code. (CVS 6290) (check-in: 97203a0a user: drh tags: trunk)
17:06		Update thread tests to clear the sqlite_open_file_count counter at the end. This counter is not threadsafe and can end up with an invalid value at the end of the thread tests. (CVS 6289) (check-in: 8c4d71a1 user: drh tags: trunk)
17:01		Fix some edge cases with backing up databases that are exactly PENDING_BYTE bytes in size, or just slightly larger. (CVS 6288) (check-in: 2fc450e8 user: danielk1977 tags: trunk)
09:36		Modify lock.test to account for "PRAGMA lock_status" returning "unknown" for in-memory databases. (CVS 6287) (check-in: 9a6e558b user: danielk1977 tags: trunk)
09:11		Fix a case where during a rollback triggered by an IO or malloc error an unjournalled region of the database could be written to (with it's original data). This was causing an assert in test_journal.c to fail. Add a test case in ioerr2.test to trigger this case. (CVS 6286) (check-in: 315a6692 user: danielk1977 tags: trunk)
2009-02-11
16:06		Updated for Windows compatibility. Test scripts only. (CVS 6285) (check-in: 2522ad1d user: shane tags: trunk)

15:11		Fix the backup.test script so that it works regardless of the value of SQLITE_TEMP_STORE and the initial contents of the file-system. (CVS 6283) (check-in: da660ea7 user: danielk1977 tags: trunk)
15:04		Add hyperlinks from sqlite3_limit() documention to the limits.html page. Comment changes only - no changes to code. (CVS 6282) (check-in: f0189ec8 user: drh tags: trunk)
14:27		Fix the crashtest infrastructure so that it doesn't trigger the "don't write to the locking region" assert in os_unix.c. (CVS 6281) (check-in: b7fd4615 user: danielk1977 tags: trunk)
07:38		Modify the test_journal.c code to (1) account for the backup code writing to parts of the pending-byte page when changing a databases page-size, and (2) to avoid reading from the pending-byte page and triggering the assert in os_unix.c. Changes to test code only. (CVS 6280) (check-in: 48796216 user: danielk1977 tags: trunk)
05:18		In test_mutex.c, zero the global structure staticly instead of in Sqlitetest_mutex_Init(). This is because Sqlitetest_mutex_Init() is now called by each thread during thread tests ((6193)). Test code changes only. (CVS 6279) (check-in: 8b318b93 user: danielk1977 tags: trunk)
2009-02-10
18:54		For the "onefile" demo, pass SQLITE_OPEN_TEMP_DB instead of MAIN_DB to the OS layer when opening the single file. This is to work around the assert() in os_unix.c that tests that the locking region is not written to. (CVS 6278) (check-in: 2da076a2 user: danielk1977 tags: trunk)
14:45		Reduce the number of iterations in one of the savepoint4.test crash tests. (CVS 6277) (check-in: fafb07b8 user: danielk1977 tags: trunk)
14:28		Prevent code in test6.c from reading the 512 byte locking region (the PENDING_BYTE page) of a database file. Doing so triggers an assert failure in os_unix.c. (CVS 6276) (check-in: 2a6a4316 user: danielk1977 tags: trunk)
13:41		Create links from backup API documentation to the backup application note. Comment changes only - no changes to code. (CVS 6275) (check-in: 85de23fb user: drh tags: trunk)
11:17		Reenable triggering vdbe tracing by creating file-system entries. Add a (redundant) test that modifying the temp schema expires all prepared statements. (CVS 6274) (check-in: f6590dac user: danielk1977 tags: trunk)
10:44		Do not always open a transaction on the temp database when writing to the main or another attached database. (CVS 6273) (check-in: f76b0b81 user: danielk1977 tags: trunk)
05:45		Fix a bug in test file misc7.test. No code changes. (CVS 6272) (check-in: d919d2a1 user: danielk1977 tags: trunk)
2009-02-09
18:55		Fix a problem in backup.c causing OsTruncate() to be called with an argument larger than the current file-size. (CVS 6271) (check-in: b34bde80 user: danielk1977 tags: trunk)
17:34		Add assert() statements to os_unix.c which fire if there is a read or write for the locking region of a database file. (CVS 6270) (check-in: 93e792ff user: drh tags: trunk)
13:19		Better error message when DISTINCT is used on an aggregate function that takes two or more arguments. Ticket #3641. (CVS 6269) (check-in: e20bf384 user: drh tags: trunk)
05:32		Ignore the return structure of and F_GETLK fcntl() call on djgpp. Fix for #3642. (CVS 6268) (check-in: 8227af34 user: danielk1977 tags: trunk)

05:59		Changes to the backup API: (1) if a negative number is passed as the second argument to backup_step(), this is interpreted as "copy all remaining pages" and (2) if backup_finish() is called after backup_step() fails with a BUSY or LOCKED error, then this error is also returned by backup_finish() (same handling as for other errors encountered by backup_step()). (CVS 6266) (check-in: 9b8c8b18 user: danielk1977 tags: trunk)
2009-02-05
17:00		Fix a test case that was still using the old pending_byte mechanism. (CVS 6265) (check-in: 08ec4f2c user: drh tags: trunk)
16:53		Fix the declaration of sqlite3PendingByte so that it works with the amalgamation. (CVS 6264) (check-in: 193c871f user: drh tags: trunk)
16:31		Make the pending byte adjustable via sqlite3_test_control() on all builds, not just on test builds. (CVS 6263) (check-in: e8f192e2 user: drh tags: trunk)
03:16		Fixed error detection in winTrucate() in os_win.c. Windows version only. Ticket #3640. (CVS 6262) (check-in: 82e03f1b user: shane tags: trunk)
03:00		Improved overrun detection in mem2.c (SQLITE_MEMDEBUG). Previously was only checking up to 3 extra bytes allocated due to rounding. (CVS 6261) (check-in: a6fe3d6b user: shane tags: trunk)
2009-02-04
22:46		Add "backup" and "restore" methods to the TCL interfaces and test cases to exercise those methods. (CVS 6260) (check-in: e420a3ce user: drh tags: trunk)
20:55		Add ".backup" and ".restore" commands to the CLI - implemented using the new backup API. (CVS 6259) (check-in: 003e1d62 user: drh tags: trunk)
20:08		Increase the version number to 3.6.11. (CVS 6258) (check-in: 0882a028 user: drh tags: trunk)
19:16		If the truncate operation fails in journalmode=TRUNCATE, do not fall back to overwriting the journal header with zeros. Simply fail the operation. (CVS 6257) (check-in: d4af60e5 user: drh tags: trunk)
17:40		Simplify wording of backup API error message. Decapitalize some other error messages. (CVS 6256) (check-in: f92405af user: drh tags: trunk)
16:56		The sqlite3_backup_init() interface must lock the destination in case it needs to change the error message. (CVS 6255) (check-in: 572378d3 user: drh tags: trunk)

11:57		Ensure that thread001.test and thread002.test reset the global shared-cache-enabled setting before they finish. (CVS 6253) (check-in: 416288a9 user: danielk1977 tags: trunk)
10:09		Do not attempt to use the sub-journal file descriptor if it is not opened (as in journal_mode=off mode). Ticket #3636. (CVS 6252) (check-in: 20bd7605 user: danielk1977 tags: trunk)
08:17		Fix a bug in malloc.test causing the exclusive permutation to fail. Changes to test code only. (CVS 6251) (check-in: 72745bde user: danielk1977 tags: trunk)
03:59		Changes to completely remove all floating point ops if SQLITE_OMIT_FLOATING_POINT defined. Note that w/o fp, date/time, round, nan, etc. are all gone or limited in functionality. Updated some of the test scripts to support missing fp and 64-bit functionality. Ticket #3029. (CVS 6250) (check-in: 5cef4000 user: shane tags: trunk)
01:49		Remove compiler warnings under MSVC. (CVS 6249) (check-in: 6301f08a user: shane tags: trunk)
2009-02-03
22:51		Correction to check-ins (6246) and (6247): The backup object might not hold a valid destination connection pointer. Also, do not reset the page cache when establishing a read-lock while there is a persistent or truncated journal, only if there is a journal that really needs to rollback. Otherwise backups always reset whenever the source database file is read. (CVS 6248) (check-in: 7f827ba9 user: drh tags: trunk)
22:17		A backup must clear the internal schema of the destination database so that the schema will be reloaded for the next sqlite3_prepare() (CVS 6247) (check-in: 76f23a43 user: drh tags: trunk)
21:13		Must hold mutex on the destination during backups. Add documentation to warn programmers that attempting to use the destination connection during a backup can lead to deadlock. (CVS 6246) (check-in: 5f6c06b9 user: drh tags: trunk)
19:55		Fixed postToParent() return type (Tcl_ThreadCreateType) in test_thread.c to compile with MSVC. Removed a few compiler warnings. Test harness change only. (CVS 6245) (check-in: e9475aba user: shane tags: trunk)

16:25		Fix the sqlite3_mprintf_long test command (added by check-in (6224) in order to address ticket #3621) so that it works on systems with sizeof(int)==4 and sizeof(long)==8. (CVS 6240) (check-in: 2e45c2a8 user: drh tags: trunk)
15:50		Remove several compiler warnings. (CVS 6239) (check-in: 85e9196d user: drh tags: trunk)

15:27		Check at the write() call to work around the msdos bug in OSX actually succeeds and throw an error if it does not. #ifdef out the work-around for all platforms other than OSX. Ticket #3633. (CVS 6237) (check-in: b054b569 user: drh tags: trunk)
13:51		Add a special rule to the amalgamation generator to deal with the sqlite3OsDlSym function. Ticket #3631. (CVS 6236) (check-in: 876f874c user: drh tags: trunk)
13:19		Fix a problem in check-in (6226) which could cause an assertion fault following a malloc failure. The prior check-in was for ticket #3624. (CVS 6235) (check-in: 1ffe44e9 user: drh tags: trunk)
13:10		Check-in (6230) introduced a bugs in SUBSTR() which was caught by the fuzz tester. Fixed by this check-in. Related to ticket #3628. (CVS 6234) (check-in: cd2e7f6c user: drh tags: trunk)
2009-02-02
21:57		Make group_concat() a 1- or 2-value function, as the documentation says it should be. Use the md5sum() function to verify ticket #3179, not group_concat(). This undoes the ill-advised group_concat() change of check-in (5233). (CVS 6233) (check-in: f2ae82c4 user: drh tags: trunk)
18:03		Omit the TEMP keyword from the schema of TEMP tables created using CREATE TEMP TABLE AS SELECT ..... Ticket #3630. (CVS 6232) (check-in: 3b0a2554 user: drh tags: trunk)

19:23		Fix the SUBSTR() function so that when the 3rd argument is negative, it counts backwards from the selected start point. Ticket #3625. (CVS 6227) (check-in: 2217339b user: drh tags: trunk)
18:08		Change the replace() function to return a copy of its first argument when the 2nd argument is an empty string. Ticket #3624. (CVS 6226) (check-in: ffebf10f user: drh tags: trunk)

2009-01-29
19:27		Add test cases to make sure that keywords that we say can be used as identifiers really can be used as identifiers. These tests were inspired by ticket #3612, but they do not directly address ticket #3612. (CVS 6214) (check-in: 6041ca87 user: drh tags: trunk)
02:54		add a cvsignore file (CVS 6213) (check-in: 68c8cdd7 user: vapier tags: trunk)

2009-01-22
23:04		Fix the VACUUM command so that it does not commit a transaction when it is mistakenly run within a transaction - it should leave the transaction open. (CVS 6200) (check-in: 75cc709b user: drh tags: trunk)
17:12		Silence a C++ builder warning by writing "if( (rc = function())!=SQLITE_OK )" instead of "if( (rc = function()) )" in two places in pager.c. Ticket #3605. (CVS 6199) (check-in: 78ae96de user: danielk1977 tags: trunk)
2009-01-21
17:45		Add a comment to fts3_tokenizer.h to make it clear how the xNext() method is supposed to set its output variables. Make sure the output variables of xNext() are only used if SQLITE_OK is returned. Ticket #3604. (CVS 6198) (check-in: 5b3c075f user: danielk1977 tags: trunk)
2009-01-20

2009-01-19
20:49		Make sure the *pzErrMsg return from sqlite3_get_table() is aways zeroed. Ticket #3598. (CVS 6195) (check-in: 7035c35d user: drh tags: trunk)

16:59		Fix a bug that was preventing SQLite from releasing locks properly under obscure circumstances. (CVS 6192) (check-in: 502c66df user: danielk1977 tags: trunk)
15:53		Back out the Makefile.in changes from check-in (6181) because of reports (ticket #3594) that they do not work on NetBSD. Separately, documentation is updated to make clear that configure and Makefile.in are unsupported. (CVS 6191) (check-in: 2d79aaab user: drh tags: trunk)

2009-01-10
18:51		Do not run crash8.test as part of the "journaltest" permutation. crash8.test uses "PRAGMA synchronous=off", which is incompatible with journaltest. (CVS 6162) (check-in: 5f184da6 user: danielk1977 tags: trunk)
17:57		Remove the unused Pager.alwaysRollback flag. Fix a couple of comments in pager.c. (CVS 6161) (check-in: 8f0672af user: danielk1977 tags: trunk)
