2013-10-24
19:48
Update the interface to the sqlite3GenerateRowDelete() utility so that it is able to handle WITHOUT ROWID tables. The implementation still needs to be completed. (check-in: 85daf517 user: drh tags: omit-rowid)
15:20
Add the ".open" command to the command-line shell. (check-in: 21eccb91 user: drh tags: trunk)

Delete PRIMARY KEY index entries last. Only construct the unique prefix of an index key when deleting entries from an index. (check-in: 0e56ba69 user: drh tags: omit-rowid)
11:55
Remove an obsolete comment from the VDBE. No code changes. (check-in: 53bb070c user: drh tags: omit-rowid)

2013-10-22
18:01
The Index object now has nKeyCol and nColumn. nColumn is the total number of columns and nKeyCol is the number of key columns. Currently these always differ by one. Refactor aiColumn[] to be of type i16 instead of int. (check-in: a106ce86 user: drh tags: omit-rowid)
14:28
Add a procedure to handle the messy details of allocating an Index object from the heap. (check-in: 45efc94f user: drh tags: omit-rowid)
10:23
Extra backwards-compatibility tests verify that UNIQUE and PRIMARY KEY indices are created in the correct order. Other backwards-compatibility tests already cover this, but it does not hurt to double up. (check-in: 5ca0ea2e user: drh tags: omit-rowid)
01:18
Previous refactor is not going to be helpful because implied indices must be created in the same order that they appear in the CREATE TABLE statement for backwards compatibility. This is a much smaller change to clean up a few loose ends. (check-in: 824b549f user: drh tags: omit-rowid)
2013-10-21

2013-10-19
23:31
Experimental changes toward "index only" tables. Add the ability to specify options on CREATE TABLE statements using the WITH clause modeled after PostgreSQL and SQL Server. Only the "omit_rowid" option is currently recognized and that option is currently a no-op. (check-in: 0248ec5e user: drh tags: omit-rowid)

12:38
Estimate row sizes for tables and indices and use those estimates during query planning. Enhance the index_info pragma to show the estimated row sizes and to show the estimated row size for the main table as well. Allow an alternative row size estimate to be specified in the sqlite_stat1 table. (check-in: d27b88b8 user: drh tags: trunk)
2013-10-09

Fix compilation issue with MSVC. (check-in: 36d64dc3 user: mistachkin tags: trunk)
17:32
Multiply all cursor step cost estimates by the estimated size of the row in bytes, in order to get the query planner ot make use of estimated row sizes. This check-in uses magic numbers in a few places (for example, estimates of the size of output rows) and needs lots of refinement. Consider this a proof-of-concept only. (check-in: cb34cfe5 user: drh tags: row-size-est)

19:18
Completely remove the iScanRatio field. The PRAGMA index_list(TABLE) command shows the estimated row size in the forth column. It also generates a row for the table with an index name of NULL. The query planner still does not take row size estimates into account - that is the next step. (check-in: 8b4aa0c7 user: drh tags: row-size-est)
18:32
Improvements to the LogEst command-line tool used to convert between ordinary numbers and the LogEst representation. (check-in: 5252aeb6 user: drh tags: row-size-est)
18:16
Begin an experimental refactoring to estimate the average number of bytes in table and index rows and to use that information in query planner. Begin by renaming WhereCost to LogEst and making that type and its conversion routines available outside of where.c. (check-in: 66c4a251 user: drh tags: row-size-est)
02:56

Further refinements of the index scanning speed logic. (check-in: e5d9371d user: drh tags: index-scan-rate)
18:17
If an "INSERT INTO ... SELECT" can use the xfer optimization, pass the OPFLAG_BULKCSR hint to btree cursors used to update indices. This results in a tighter key packing. (check-in: 087af29e user: dan tags: trunk)
15:58
Fix test cases so that they work when the query planner uses index size estimates to determine whether or not to try an covering index scan. (check-in: 2f394de8 user: drh tags: index-scan-rate)
15:30
Improved estimates of the relative speed of index scans based on declared datatypes of columns in the table. Add "r" column to PRAGMA index_info, showing the estimated relative scan rate. (check-in: 07462bb6 user: drh tags: index-scan-rate)

Allow FTS4 multi-token phrases to use a combination of in-memory and incrementally loaded doclists. This allows phrases to (partially) benefit from incremental doclists without disabling the deferred token optimization. (check-in: f6819c5f user: dan tags: fts4-docid-range-constraints)
19:21
Experimental branch allowing different postulated scan rates for each index. (check-in: d59d97b0 user: drh tags: index-scan-rate)

The sqlite3FixInit() routine cannot fail. So change the return type from "int" to "void". (check-in: 500c5932 user: drh tags: trunk)
14:08
Rework the PRAGMA implementation to only call sqlite3ReadSchema() from a single place, based on a flag in the pragma table, rather than separately from each case which needs the schema. (check-in: 8338232a user: drh tags: trunk)
12:29
Return an error if an attempt is made to create a trigger with an SQL variable embedded within it. If such a variable reference is found within a trigger definition loaded from the sqlite_master table, silently replace it with a NULL. (check-in: f35f6ae3 user: dan tags: trunk)

23:22
Add logic to the query planner to only use partial indices if the WHERE clause constrains the search to rows covered by the partial index. This is just infrastructure. The key routine, sqlite3ExprImpliesExpr(), is currently a no-op so that partial indices will never be used. (check-in: 8ca3eac1 user: drh tags: partial-indices)

Add the experimental "query_only" pragma. (check-in: 6557c407 user: drh tags: trunk)
15:03
Add the "defer_foreign_keys" pragma and the SQLITE_DBSTATUS_DEFERRED_FKS value for sqlite3_db_status(). This is a cherry-pick of a sequence of five checkins in the sessions branch between [1d44e5d3c2] and [d39e65fe70]. (check-in: 527121ac user: drh tags: trunk)

2013-05-31
20:43
The NGQP might not find a solution if INDEXED BY constraints on the query are set wrong. If that is the case, print a "no query solution" error and abort before trying to use the non-existant solution. (check-in: 42511a7e user: drh tags: nextgen-query-plan-exp)
20:28
Do not search using ON clause constraints of LEFT JOINs to the right of the table. (check-in: 723f901a user: drh tags: nextgen-query-plan-exp)

Make sure a unique cursor number is allocated for automatic indices. (check-in: 433d1aec user: drh tags: nextgen-query-plan-exp)
19:14
Do not attempt to generate code in the NGQP if there have been prior errors, since with prior errors some of the expressions might not be fully named resolved. (check-in: 665e4291 user: drh tags: nextgen-query-plan-exp)

19:29
Futher simplifications to the NGQP. Fix some test cases to use EXPLAIN QUERY PLAN rather than the (now obsolete) sqlite_query_plan global variable. (check-in: ae985db4 user: drh tags: nextgen-query-plan-exp)
19:28
The expected result in a test case can be of the form "*glob*" or "~*glob*" to match or not match the GLOB pattern. This is useful for matching EXPLAIN QUERY PLAN output that contains regular expression syntax characters like "?", "(", and ")". (check-in: a3b4e261 user: drh tags: nextgen-query-plan-exp)
17:43
Cut over the NGQP query planner. Remove lots of legacy code. This check-in compiles but does not work. The test suite gets incorrect answers and crashes. (check-in: 001539df user: drh tags: nextgen-query-plan-exp)

When writing to an FTS table, take an exclusive shared-cache lock on the %_segdir table before writing. Otherwise, an xCommit() call may report an SQLITE_LOCKED error. (check-in: 3cd2da42 user: dan tags: trunk)
2013-05-24
14:52
Record in the WhereLoop object the set of virtual table constraints that need not be separately checked. (check-in: b49fa745 user: drh tags: nextgen-query-plan-exp)

01:40
Cause the mmap_size PRAGMA to immediately change the mmap space if the database connection is already active. In particular, reducing mmap_size will immediately free up process address space. (check-in: 76117792 user: drh tags: trunk)
2013-05-22
20:49
Use the NGQP plan for EXPLAIN QUERY PLAN output. This change causes 207 errors in veryquick.test, many of which are benign. (check-in: f783e8e6 user: drh tags: nextgen-query-plan-exp)

17:15
Fix a bug in SQLITE_TRACE_SIZE_LIMIT that was introduced by check-in [1a1cf5aa86734c8]. That check-in was to remove harmless compiler warnings. So once again, we have introduced a real bug into SQLite by attempting to eliminate a harmless compiler warning. (check-in: cec2bcb4 user: drh tags: trunk)
16:41
In test file test_syscall.c, include sqliteInt.h before any tcl or system include files. This ensures that the magical defines in sqliteInt.h really do enable large file support (and set things up so that sizeof(off_t)==8). (check-in: 0f355bb1 user: dan tags: trunk)
12:52

17:08
Make sure an sqlite3_close() or a rollback on one shared-cache connection does not disrupt the operation of other connections using the same shared cache. Fix for ticket [e636a050b709]. (check-in: 5cc1cc55 user: drh tags: trunk)

13:05
Add the rot13.c loadable extension. (check-in: 8f9bd8e7 user: drh tags: trunk)
10:21
When closing a connection, avoid tripping active cursors belonging to a different shared-cache client.

Expand scope of the SQLITE_MAX_MMAP_SIZE define for the Win32 VFS. (check-in: f4b8faab user: mistachkin tags: trunk)
17:03
Refactoring the mmap interface. The controlling pragma is now "mmap_size" instead of "mmap_limit". Also change SQLITE_CONFIG_MMAP_LIMIT and SQLITE_FCNTL_MMAP_LIMIT to SQLITE_CONFIG_MMAP_SIZE and SQLITE_FCNTL_MMAP_SIZE, respecctively. The default mmap_size is now always 0, meaning that memory mapped I/O is off by default. There is a new compile-time option SQLITE_MAX_MMAP_SIZE that determines a hard upper bound on the mmap_size. Setting SQLITE_MAX_MMAP_SIZE to zero disables the memory-mapped I/O logic and causes it to be omitted from the build. An extra argument is added to SQLITE_CONFIG_MMAP_SIZE that can optionally lower the SQLITE_MAX_MMAP_SIZE at start-time. The SQLITE_MAX_MMAP_SIZE is zero for platforms where we know that it does not work, meaning that it cannot be turned on by mistake on those platforms. (check-in: ea1404a1 user: drh tags: trunk)

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)

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)

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.

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.

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.

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.

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)

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)

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)

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.

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)

When non-aggregate columns occur in an aggregate query with a single min() or max(), then the values of the non-aggregate columns are taken from one of the rows that was the min() or max(). (check-in: fa13edd3 user: drh tags: trunk)
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)

18:00
Fix compiler warnings in the TCL test harness. (check-in: c4cd38a0 user: drh tags: trunk)
16:02
Do not rely on the _WIN32_WINNT macro as vs2005 does not define it by default. Instead, always assume winNT unless the makefile explicitly sets SQLITE_OS_WINNT=0. (check-in: 1ce4d21d user: drh tags: trunk)
2012-01-28
21:08
Update the .dump command of the command-line shell so that it (1) avoids putting the semicolon of a DDL statement on the same line as a comment, (2) avoids long expression, even when dumping a table with many columns, and (3) avoids unnecessary quoting of the table name. This fixes tickets [c04a8b8a4f] and [232637c465]. Shell change only; no changes to the SQLite core. (check-in: e6eea8d5 user: drh tags: trunk)
19:44
Remove a couple of unnecessary nonterminals from the grammar. (check-in: 2b2a7d8d user: drh tags: trunk)

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

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)

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)

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)

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)

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)
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)

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)

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)

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)

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

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)

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)

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)

2011-12-13
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)

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)
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)

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)
