22 check-ins related to "auto-analyze"

2017-03-06
17:33
Add an initial implementation of the "PRAGMA optimize" command. check-in: 137aeb2b user: drh tags: trunk
11:39
Merge updates from trunk. Closed-Leaf check-in: 5f7fc79a user: drh tags: auto-analyze
2017-03-03
21:51
If a reprepare is needed after binding to a variable with a number larger than 32, set only the high-order bit of the Vdbe.expmask rather than setting all bits. This could potentially result in fewer false-positive reprepares. check-in: 45797fee user: drh tags: trunk
2017-03-02
14:17
Add an optional bitmask of allowed optimizations on the "PRAGMA optimize" command. The 0x01 bit is Debug Mode. check-in: a35388ee user: drh tags: auto-analyze
13:22
Merge recent trunk enhancements. check-in: c60cdb47 user: drh tags: auto-analyze
13:13
Make sure the Vdbe.expmask value is set correctly in sqlite3VdbeSwap(). This fixes a problem introduced by [a8fd7052]. check-in: 29f54b89 user: drh tags: trunk
2017-02-23
02:15
Add two NEVER() operators in the sqlite3BtreeRowCountEst() routine. check-in: 7a959f6d user: drh tags: auto-analyze
00:58
Do a single OP_Expire at the very end of "PRAGMA optimize", and omit the OP_Expire on ANALYZE commands invoked by the pragma. check-in: 188300a3 user: drh tags: auto-analyze
2017-02-22
20:24
Change the name of the analyze_as_needed pragma to "optimize". Enhance the comment (which will become documentation, assuming these changes land on trunk) to explain that the optimize pragma is likely to be enhanced in various ways in future releases and that applications should not depend upon the current behavior. check-in: 9fced545 user: drh tags: auto-analyze
19:49
Merge integrity_check and other improvements from trunk. check-in: fe073905 user: drh tags: auto-analyze
19:41
Move a branch condition in analyze.c inside an #ifdef SQLITE_ENABLE_STAT4 block. check-in: d6afd98d user: dan tags: trunk
2017-02-20
13:11
Merge fixes from trunk. check-in: ff213f2e user: drh tags: auto-analyze
2017-02-18
22:52
Updated comments. No code changes. check-in: e842ad39 user: drh tags: auto-analyze
15:58
Add the OP_SqlExec opcode and use it to implement "PRAGMA analyze_as_needed", invoking ANALYZE subcommands as necessary. This simplifies the implementation. check-in: d386015f user: drh tags: auto-analyze
13:47
Add the SQLITE_BUG_COMPATIBLE_20160819 compile-time option to omit the error message when an unrecognized argument is provided to the VACUUM command. check-in: 49181427 user: drh tags: trunk
02:42
Fix errors in the table resize detection. check-in: 4229caec user: drh tags: auto-analyze
02:19
In the analyze_as_needed pragma, avoid running unnecessary OP_LoadAnalysis and OP_Expire opcodes. Make the analyze_as_needed pragma responsive to the schema name. check-in: 882599a4 user: drh tags: auto-analyze
2017-02-17
19:24
The analyze_as_needed pragma now responds to table size growth and will automatically rerun the analysis after each 10x size increase. check-in: bfbdd074 user: drh tags: auto-analyze
16:26
Add the "PRAGMA analyze_as_needed" command. check-in: e93db237 user: drh tags: auto-analyze
15:26
Set the TF_StatsUsed flag on tables when the query planner outcome is affected by the sqlite_stat1 data. Also, change the column names of the "PRAGMA stats" command so that they are not keywords. check-in: fb2b8ae8 user: drh tags: auto-analyze
13:38
Enhance the Index and Table objects so that they remember if their stats come from the sqlite_stat1 table. Make the "PRAGMA stats" an SQLITE_DEBUG only pragma. Add the flags column to "PRAGMA stats". These are all preliminary steps toward a "PRAGMA analyze_ifneeded;" feature. check-in: 85026c8e user: drh tags: auto-analyze
02:04
Fix a test case that was made to fail by the LIKE optimization enhancement in check-in [158290c0ab] but which went unnoticed because test builds were running with ICU enabled and ICU disables the LIKE optimization. check-in: 218b2bbb user: drh tags: trunk
