2012-12-14
| ||
| 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: d6e045f89c user: drh tags: vtab-IN-opt) | |
|
2012-12-13
| ||
| 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: 7280e14cd8 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: 120c82d56e user: drh tags: trunk) | |
| 13:36 | Version 3.7.15 (check-in: cd0b37c526 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: 81d9ee0f0d user: drh tags: trunk) | |
| 19:10 | Fix a typo in a comment that is used to generate documentation. No changes to code. (check-in: e38adb60a7 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: bd7aeeb691 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: 75e545a9e2 user: dan tags: trunk) | |
| 09:08 | Remove a reference to JumpOnce from a comment in vdbe.c. No code changes. (check-in: ee662c039d 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: 4f6d69ae94 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: 92c9ab56b1 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: 8542e6180d 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: cdbfa66483 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: b3f5366811 user: drh tags: ticket-71e333e7) | |
| 13:26 | Fix the header comment on the OP_Compare operator. (check-in: 2722f4074f user: drh tags: ticket-71e333e7) | |
| 06:46 | Merge updates from trunk. (check-in: e65db42c9f 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: 1a9db8dc2f user: drh tags: ticket-71e333e7) | |
| 03:34 | Veryquick passes all tests now. (check-in: 7b96115e81 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: f66c1db296 user: drh tags: ticket-71e333e7) | |
|
2012-12-07
| ||

| 23:10 | For an ORDER BY on a compound SELECT, take the collating sequence from the left-most term of the compound. (check-in: 8e724b383d user: drh tags: ticket-71e333e7) | |
| 22:54 | Do not report missing collating functions while parsing the schema. Also remove a stray comment. (check-in: e313edca04 user: drh tags: ticket-71e333e7) | |
| 22:18 | Fix a long-standing issue with the distinct-as-aggregate optimization that only expressed when the new collating-sequence logic is turned on. (check-in: 0aaf52a339 user: drh tags: ticket-71e333e7) | |
| 21:02 | Fix the processing of ORDER BY clauses with COLLATE terms on compound queries. 52 veryquick test failures remain. (check-in: 49654453ad user: drh tags: ticket-71e333e7) | |
| 20:31 | Many more tests are passing. Only about 100 failures remain in veryquick. (check-in: f9fa7581c0 user: drh tags: ticket-71e333e7) | |
| 19:28 | Ensure the VerifyCookie sub-routine has been run before the database is accessed in an obscure case. Fix for ticket [d6b36be38]. (check-in: 2d5f37c99a user: dan tags: trunk) | |
| 18:38 | Some errors in veryquick resolved. Many more to go. (check-in: 972443b4eb user: drh tags: ticket-71e333e7) | |
| 14:02 | Veryquick now runs to completion without segfaulting or asserting. But there are still lots of errors. (check-in: 7fafab12e4 user: drh tags: ticket-71e333e7) | |
| 10:55 | Do not run test file malloc3.test as part of the inmemory_journal permutation. Explanation is in a comment at the top of malloc3.test. (check-in: df1827b19e user: dan tags: trunk) | |
| 09:08 | Spelling and header fixes for the async extension. (check-in: 930ba85262 user: mistachkin tags: trunk) | |
|
2012-12-06
| ||
| 23:16 | In the async VFS, treat the new error code SQLITE_IOERR_DELETE_NOENT as success for xDelete. (check-in: c507ca4a8e 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: fd011cb22f user: drh tags: ticket-71e333e7) | |
| 19:41 | Merge the constant-refactoring-in-triggers branch with the trunk. (check-in: 79ef8e3c77 user: dan tags: trunk) | |
| 19:37 | Apply the same restrictions on constant refactoring to statements within a trigger program as top-level statements. Candidate fix for [ae3c5670b6]. (Closed-Leaf check-in: 0c31a46801 user: dan tags: constant-refactoring-in-triggers) | |
| 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: 1a63b1d5fa user: drh tags: trunk) | |
| 15:15 | Add a test case that demonstrates ticket [71e333e7d2e642]. (check-in: cc6e0785df user: drh tags: ticket-71e333e7) | |
| 04:33 | For the sqlite3-all.c target, use backslashes when calling the splitter script via the MSVC makefile. (check-in: d507648d82 user: mistachkin tags: trunk) | |
| 04:19 | Bring the ancient malloc3.test file closer into relevance with the latest core code. (check-in: 9793a21c13 user: mistachkin tags: trunk) | |
| 02:56 | Stop using the TCL_LIBS configuration variable when linking with Tcl. Remove superfluous 'rm' command from the "clean" target. (check-in: 1551277208 user: drh tags: trunk) | |
| 01:03 | Remove obsolete comments from the definition of the CollSeq object. (check-in: 7b6951016f user: drh tags: trunk) | |
| 00:16 | Stop using the TCL_LIBS configuration variable when linking with Tcl. Remove superfluous 'rm' command. (Closed-Leaf check-in: e1feab9834 user: mistachkin tags: noTclLibs) | |
|
2012-12-05
| ||
| 19:04 | Disable a couple of tests in where.test when running the "no_optimization" permutation. (check-in: 5e961e37c5 user: dan tags: trunk) | |
| 16:44 | Modify a query in test/thread001.test to ensure that results are returned in the order expected by the test. (check-in: 51cbddd51d 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: 40c143955e 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: 9f6c68856b 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: bdceca2738 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: 11aa47b0a8 user: dan tags: trunk) | |
| 09:12 | Update a couple of test scripts so that they work in auto-vacuum mode. (check-in: 04ab2dc691 user: dan tags: trunk) | |
|
2012-12-04
| ||
| 11:03 | Fix a harmless compiler warning. (check-in: 12693deba9 user: drh tags: trunk) | |
| 05:24 | Add a test to ensure that the fix in [b0c1ba655d] has worked. (check-in: 41806de5c8 user: dan tags: trunk) | |
| 05:21 | Add a test to ensure that the fix in [b0c1ba655d] has worked. (Closed-Leaf check-in: 59c233942e user: dan tags: mistake) | |
| 00:59 | Improvements to the 'tcl' shell output mode. Escape doublequotes, set separator to space when mode is set, and skip separator after final column. (check-in: 487ba75313 user: drh tags: trunk) | |
| 00:53 | Fix an uninitialized variable detected by valgrind. (check-in: ffd1e51490 user: drh tags: trunk) | |
| 00:37 | Fix an out-of-order function declaration when compiled with MEMDEBUG. (check-in: 6d31557837 user: mistachkin tags: trunk) | |

|
2012-12-03
| ||
| 19:42 | Remove an unreachable condition. Replace it with an assert(). (check-in: 7d5fc1a339 user: drh 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: b0c1ba655d 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: 2e5e651527 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: 3d548db7eb 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: ba8d08b670 user: drh tags: sessions) | |
| 21:22 | Add the SQLLOG capability to trunk. (check-in: f0843f885a user: drh tags: trunk) | |
| 21:12 | Improved detection of file-does-not-exist in winDelete. (check-in: 92e9b5bc05 user: drh tags: trunk) | |
| 16:39 | Get SQLLOG working on windows. Fix a couple of compiler warnings. (Closed-Leaf check-in: b3809c937b user: drh tags: sqllog) | |
| 15:56 | Fix a problem causing the "number-of-documents" field maintained by FTS4 to be set incorrectly by REPLACE queries. (check-in: e38fb02d5e user: dan 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: 429c5b2056 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: cd501bbccf 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: 692ad3c02b 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: d4c36d4991 user: drh tags: trunk) | |
|
2012-11-13
| ||
| 11:16 | Strive to use posix_fallocate() rather than ftruncate() when posix_fallocate() is available. Ticket [5eaa61ea18]. (check-in: 29980b08ec 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: 597333f102 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: 356259617c user: drh tags: tkt-5eaa61ea18) | |
|
2012-11-10
| ||
| 01:27 | Merge the latest changes from trunk: chiefly the outer/inner loop query optimizer scoring enhancement and the INSTR() function. (check-in: 2993ca2020 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: 5a3b07f0f5 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: bed9c172ce 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: 3f87f4593b 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: 51bfd63b7f user: drh tags: inner-loop-cost) | |
| 17:59 | Try to take into account the cost of inner loops when selecting which table of a join to use for the outer loop. (check-in: 942556342a user: drh tags: inner-loop-cost) | |
|
2012-11-06
| ||
| 20:39 | Adjust the SQLITE_DBSTATUS_STMT_USED calculation to take the modified usage of sqlite3VdbeClearObject() into account. (check-in: 82eb7eadb8 user: mistachkin tags: trunk) | |
| 18:41 | In test_quota.c, provide a work-around for the missing _chsize_s() function in mingw. (check-in: 6b4979e86c user: drh tags: trunk) | |

| 21:03 | Pull all the latest trunk enhancements into the sessions branch. (check-in: fce667f2d9 user: drh tags: sessions) | |
| 18:09 | Enable the use of coroutines as an alternative to manifesting views used in a FROM clause. (check-in: 9dca18f5fe user: drh tags: trunk) | |
| 15:31 | Make sure that the optimizer never tries to create an automatic index on a coroutine subquery. (Closed-Leaf check-in: f83aa0de84 user: drh tags: subquery-as-coroutine) | |
| 14:44 | Fix a typo in the header comment for the OpenPseudo opcode. (check-in: 4f1061230e 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: 564631f3e4 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: 7af3acbbd4 user: drh tags: subquery-as-coroutine) | |
|
2012-10-29

| 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: 317c80cba3 user: drh tags: trunk) | |
