29 check-ins using file src/sqlite.h.in version 442c109e

2013-08-07
16:38
Fix typos in a comment in analyze.c. No code changes. (check-in: 812ed0c5 user: dan tags: sqlite_stat4)
16:15
Change the way samples for the sqlite_stat4 table are collected. (check-in: 13ed5ac1 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: 1e80c4b1 user: drh tags: sqlite_stat4)
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)
01:18
Fix typos and add clarification to comments in where.c. No code changes. (check-in: f8d8790e user: drh tags: trunk)
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)
19:18
Fix a test case related to partial indices so that it works even if STAT3 is disabled. (check-in: 153c6450 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: 89930ea3 user: drh tags: trunk)
18:21
Update the configure script to use the latest version number (3.8.0). (check-in: 52e8ec5e user: drh tags: trunk)
17:24
Add a testcase() macro to verify OOM coverage. (check-in: d43dcbc4 user: drh tags: trunk)
16:56
Remove unreachable branches in expr.c, replacing them with assert() and testcase() statements. (check-in: 9103c27c user: drh tags: trunk)
14:36
For the ".import" command of the command-line shell, start a transaction if there is not one active already. (check-in: 5dcc2d91 user: drh tags: trunk)
14:01
Clean up the input reader in the command-line shell for improved legibility and performance. (check-in: 2b1743d6 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: 924f7e4d user: drh tags: trunk)
2013-08-05
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)
20:11
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)
13:31
Fix typos in documentation for SQLITE_DBSTATUS_DEFERRED_FKS . No changes to code. (check-in: f3efbfcd user: drh tags: trunk)
