| 18:07 | Merge in the latest changes from trunk. (Closed-Leaf check-in: c78b0d302c user: drh tags: uri-enhancement) | |
| 16:38 | Fix typos in a comment in analyze.c. No code changes. (check-in: 812ed0c58f user: dan tags: sqlite_stat4) | |
| 16:15 | Change the way samples for the sqlite_stat4 table are collected. (check-in: 13ed5ac135 user: dan tags: sqlite_stat4) | |
| 16:04 | Fix the ".dump" command on the command-line shell so that it works for "sqlite_stat4" in addition to "sqlite_stat1". (check-in: 1e80c4b12d user: drh tags: sqlite_stat4) | |
| 15:57 | Remove the unused sqlite3Utf8to16() utility function. (check-in: 9159b43eb2 user: drh tags: sqlite_stat4) | |
| 15:52 | When estimating the number of rows scanned using data from the sqlite_stat4 table, avoid allocating UnpackedRecord and KeyInfo structures until they are definitely required. (check-in: 353950a526 user: dan tags: sqlite_stat4) | |
| 14:18 | Add a guard #ifndef to test_intarray.h to prevent harm if it is #included more than once. Add a comment on the closing #endif of the guards on sqlite3.h and test_multiplex.h. (check-in: 0ad83ceb79 user: drh tags: trunk) | |
| 01:18 | Fix typos and add clarification to comments in where.c. No code changes. (check-in: f8d8790ede user: drh tags: trunk) | |

| 20:15 | Fixes for builds without SQLITE_ENABLE_STAT4. (check-in: 84999e27cc user: dan tags: sqlite_stat4) | |
| 20:01 | When possible, use the multi-column samples in sqlite_stat4 to estimate the number of index rows scanned by a query plan. (check-in: 2973f5ca73 user: dan tags: sqlite_stat4) | |
| 19:18 | Fix a test case related to partial indices so that it works even if STAT3 is disabled. (check-in: 153c645025 user: drh tags: trunk) | |
| 18:35 | Adjust #ifdefs in test_autoext.c so that it compiles with SQLITE_OMIT_LOAD_EXTENSION. Fix compiler warnings in two other test modules. No changes to the core. (check-in: 89930ea3c3 user: drh tags: trunk) | |
| 18:21 | Update the configure script to use the latest version number (3.8.0). (check-in: 52e8ec5e24 user: drh tags: trunk) | |
| 17:24 | Add a testcase() macro to verify OOM coverage. (check-in: d43dcbc488 user: drh tags: trunk) | |
| 16:56 | Remove unreachable branches in expr.c, replacing them with assert() and testcase() statements. (check-in: 9103c27ceb user: drh tags: trunk) | |
| 14:52 | Merge in the latest changes from trunk. (check-in: 69d5bed017 user: drh tags: sessions) | |
| 14:36 | For the ".import" command of the command-line shell, start a transaction if there is not one active already. (check-in: 5dcc2d91bd user: drh tags: trunk) | |
| 14:01 | Clean up the input reader in the command-line shell for improved legibility and performance. (check-in: 2b1743d601 user: drh tags: trunk) | |
| 07:45 | More than double the speed of the resolveP2Values() routine in vdbeaux.c by moving from an extended if-else on every opcode to a switch. Opcodes are reordered in mkopcodesh.awk to put the switched opcodes close together, for additional performance and to reduce code footprint. (check-in: 924f7e4d7a user: drh tags: trunk) | |

| 22:05 | Performance optimization: Avoid calling convertCompoundSelecctToSubquery() on queries that do not use the UNION, EXCEPT, or INTERSECT operators. (check-in: c589b2fed7 user: drh tags: trunk) | |
| 21:54 | For the vtshim module, always zero out the xChildDestroy function pointer after calling it. (check-in: 240f7252c6 user: mistachkin tags: trunk) | |
| 19:11 | Factor all KeyInfo object allocations into a single function: sqlite3KeyInfoAlloc(). Always allocate enough space so that sqlite3VdbeRecordCompare() can avoid checking boundaries and hence run faster. (check-in: 7301bedd94 user: drh tags: trunk) | |
| 19:04 | Modify the vdbe code generated by ANALYZE to use fewer memory cells and cursor slots. (check-in: 4a51cf289f user: dan tags: sqlite_stat4) | |
| 18:00 | Use N separate cursors when scanning an index with N columns to collect sqlite_stat4 data. This fixes a problem with collecting incorrect nEq values from multi-column indexes. (check-in: 3a71afe674 user: dan tags: sqlite_stat4) | |
| 15:32 | Improve performance of sqlite3VdbeRecordCompare() by using an approximation that might give false negatives and only running the more expensive exact subexpression if the approximation fails. (check-in: 28979dcd16 user: drh tags: trunk) | |
| 12:31 | Add a missing '#include "tcl.h"' to test_rtree.c. (check-in: 4b8b426f10 user: drh tags: trunk) | |
| 05:34 | Fix a couple of problems in code related to sqlite_stat4. (check-in: badd24d987 user: dan tags: sqlite_stat4) | |

| 20:24 | Begin adding experimental sqlite_stat4 table. This commit is buggy. (check-in: 2beea303a1 user: dan tags: sqlite_stat4) | |
|
2013-08-02
| ||
| 23:40 | Updates to requirements marks. No code changes. (check-in: 213020769f user: drh tags: trunk) | |
| 20:44 | Merge in the latest trunk changes, including partial indexes, the MAX_PATH fix in os_win.c, and the sqlite3_cancel_auto_extension() API. (check-in: 7e1acb3907 user: drh tags: sessions) | |
| 20:11 | Add NEVER() and ALWAYS() macros on some unreachable yet prudent branches. (check-in: c5c0a8ab6c user: drh tags: trunk) | |
| 16:41 | Add support for partial indices. (check-in: 478113f18b user: drh tags: trunk) | |
| 14:18 | Silently ignore database name qualifiers in CHECK constraints and in partial index WHERE clauses. (Closed-Leaf check-in: 2e8c845eb5 user: drh tags: partial-indices) | |
| 13:31 | Fix typos in documentation for SQLITE_DBSTATUS_DEFERRED_FKS . No changes to code. (check-in: f3efbfcd51 user: drh tags: trunk) | |
|
2013-08-01
| ||
| 22:27 | Fix the CREATE INDEX statement so that trying to create a TEMP index on a non-TEMP table throws an error rather than segfaulting. (check-in: e3c8935f87 user: drh tags: trunk) | |
| 22:26 | Fix an incorrect expected result in a test case in corruptG.test. (check-in: 6913831ad2 user: drh tags: trunk) | |
| 20:26 | Fix a potential buffer overread in sqlite3VdbeRecordCompare() when a serial_type specifies a field that starts in bounds but is much too large for the allocated buffer. Mostly harmless. The overread is unlikely to go more than one or two bytes past the end of the buffer. (check-in: e436b2f4e5 user: drh tags: trunk) | |
| 19:17 | Make sure signed integer overflow does not cause a segfault while attempting to read a corrupt database where the header size varint on a record is larger than the maximum 32-bit signed integer. (check-in: c3baca99f4 user: drh tags: trunk) | |
| 17:43 | Add test case for the problem fixed by [127a5b776d]. (check-in: 65816718b5 user: dan tags: trunk) | |
| 17:21 | An improved method for avoiding the use of the STAT3 samples to compute the estimated number of outputs when the left-most index is equality constrained. This check-in undoes the previous fix and applies a new one. (check-in: 127a5b776d user: drh tags: trunk) | |
| 16:52 | Avoid using left-most column STAT3 samples if the left-most column has an equality constrain and there are inequality constraints on the second column. (check-in: 31b4e63b3c user: drh tags: trunk) | |
| 16:02 | Fix bug in the logic that determines the end of a CREATE INDEX statement. Added a VACUUM test case that exposed the bug. (check-in: 2e3df0bc90 user: drh tags: partial-indices) | |
| 15:09 | More test cases and corresponding bug fixes. (check-in: 0c8cfdfae2 user: drh tags: partial-indices) | |
| 13:04 | Fill out an initial implementation of the sqlite3ExprImpliesExpr() function. (check-in: 8e07aa2ad5 user: drh tags: partial-indices) | |
| 12:21 | Refactor internal function name sqlite3VdbeGetValue() to sqlite3VdbeGetBoundValue(). (check-in: 81834c3023 user: drh tags: partial-indices) | |
| 04:39 | Fix the ANALYZE command to work with partial indices. (check-in: 60353124f4 user: drh tags: partial-indices) | |
| 03:36 | Test cases and bug fixes for the partial index logic. (check-in: 6b73ae7c12 user: drh tags: partial-indices) | |
| 01:14 | Add the logic to keep partial indices up to date through DML statements and when new partial indices are created. This new logic is untested except to verify that it does not interfere with full indices. (check-in: fb9044d15a user: drh tags: partial-indices) | |

| 23:28 | Limit the number of memset() calls used when determining a temporary file name on Windows. Also, fix a harmless compiler warning. (check-in: 136fc2931b user: mistachkin 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: 8ca3eac111 user: drh tags: partial-indices) | |
