| 15:57 | Remove the unused sqlite3Utf8to16() utility function. (check-in: 9159b43e 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: 353950a5 user: dan tags: sqlite_stat4) | |
|
2013-08-06
| ||
| 20:15 | Fixes for builds without SQLITE_ENABLE_STAT4. (check-in: 84999e27 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: 2973f5ca user: dan tags: sqlite_stat4) | |
| 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: 924f7e4d 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: c589b2fe user: drh tags: trunk) | |
| 21:54 | For the vtshim module, always zero out the xChildDestroy function pointer after calling it. (check-in: 240f7252 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: 7301bedd user: drh tags: trunk) | |
| 19:04 | Modify the vdbe code generated by ANALYZE to use fewer memory cells and cursor slots. (check-in: 4a51cf28 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: 3a71afe6 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: 28979dcd user: drh tags: trunk) | |
| 12:31 | Add a missing '#include "tcl.h"' to test_rtree.c. (check-in: 4b8b426f user: drh tags: trunk) | |
| 05:34 | Fix a couple of problems in code related to sqlite_stat4. (check-in: badd24d9 user: dan tags: sqlite_stat4) | |
|
2013-08-03
| ||
| 20:24 | Begin adding experimental sqlite_stat4 table. This commit is buggy. (check-in: 2beea303 user: dan tags: sqlite_stat4) | |
|
2013-08-02
| ||
| 23:40 | Updates to requirements marks. No code changes. (check-in: 21302076 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: 7e1acb39 user: drh tags: sessions) | |
| 20:11 | Add NEVER() and ALWAYS() macros on some unreachable yet prudent branches. (check-in: c5c0a8ab user: drh tags: trunk) | |
| 16:41 | Add support for partial indices. (check-in: 478113f1 user: drh tags: trunk) | |
| 14:18 | Silently ignore database name qualifiers in CHECK constraints and in partial index WHERE clauses. (Closed-Leaf check-in: 2e8c845e user: drh tags: partial-indices) | |
| 13:31 | Fix typos in documentation for SQLITE_DBSTATUS_DEFERRED_FKS . No changes to code. (check-in: f3efbfcd 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: e3c8935f user: drh tags: trunk) | |
| 22:26 | Fix an incorrect expected result in a test case in corruptG.test. (check-in: 6913831a 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: e436b2f4 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: c3baca99 user: drh tags: trunk) | |
| 17:43 | Add test case for the problem fixed by [127a5b776d]. (check-in: 65816718 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: 127a5b77 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: 31b4e63b 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: 2e3df0bc user: drh tags: partial-indices) | |
| 15:09 | More test cases and corresponding bug fixes. (check-in: 0c8cfdfa user: drh tags: partial-indices) | |
| 13:04 | Fill out an initial implementation of the sqlite3ExprImpliesExpr() function. (check-in: 8e07aa2a user: drh tags: partial-indices) | |
| 12:21 | Refactor internal function name sqlite3VdbeGetValue() to sqlite3VdbeGetBoundValue(). (check-in: 81834c30 user: drh tags: partial-indices) | |
| 04:39 | Fix the ANALYZE command to work with partial indices. (check-in: 60353124 user: drh tags: partial-indices) | |
| 03:36 | Test cases and bug fixes for the partial index logic. (check-in: 6b73ae7c 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: fb9044d1 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: 136fc293 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: 8ca3eac1 user: drh tags: partial-indices) | |
| 22:39 | Slight modifications to path name translation handling for Cygwin. (check-in: 33ba1f4c user: mistachkin tags: trunk) | |
| 22:27 | Use a new error code to represent a failure to get the configured temporary directory on Windows. (check-in: c93d891b user: mistachkin tags: trunk) | |
| 19:55 | The MAX_PATH constant in windows is measured in characters, so multiple by 3 to get the number of bytes assuming worst-case UTF8 pathnames. (check-in: bb06e157 user: drh tags: trunk) | |
| 19:05 | Resolve names in CREATE INDEX WHERE clauses and detect errors. Disallow expressions that contain variables, subqueries, or functions. The expression is still not used for anything, however. still unused. (check-in: f2aa7842 user: drh tags: partial-indices) | |
| 18:12 | Here begins an experimental branch for exploring the idea of a partial index. This check-in is able to parse a WHERE clause on a CREATE INDEX statement, but does not actually do anythingn with that WHERE clause yet. (check-in: 6794b2dc user: drh tags: partial-indices) | |

| 15:10 | Reduce the size of the stack required by the codeOneLoopStart() function in where.c. (check-in: eb6d4278 user: drh tags: trunk) | |
|
2013-07-29
| ||
| 19:03 | For the MSVC makefile, recompile vdbe.lo and parse.lo first. (check-in: 9e819f0f user: mistachkin tags: trunk) | |
| 15:54 | Comment and preprocessor macro cleanup. (check-in: c0809b5e user: drh tags: trunk) | |
| 13:51 | In main.mk, always recompile vdbe.o and parse.o first, since changes to either parse.y or vdbe.c will cause all files to be recompiled and if there are syntax errors in vdbe.c or parse.y we want to hit them early in the compile process. (check-in: a94a66d1 user: drh tags: trunk) | |
|
2013-07-25
| ||
| 17:07 | In the command-line shell, work around the fact that popen() and pclose() are not defined in stdio.h. in C89 and later. (check-in: 8bcbb33f user: drh tags: trunk) | |
