Very small enhancement to dispatch speed for SQL functions. check-in: 3c3228ed user: drh tags: trunk
14:04

13:29
Proof of concept for a "PRAGMA vdbe_cycle_limit=N" command. When N>0, invoke sqlite3_interrupt() whenever any byte code program uses more than N virtual machine cycles. Leaf check-in: 9626b41e user: drh tags: vdbe_cycle_limit
2017-02-20
23:32

Updated comments. No code changes. check-in: e842ad39 user: drh tags: auto-analyze
20:05
Add an optimization to OP_Column to speed up sequential OP_Column instructions that read earlier fields from the same cursor. Attempt to reorder OP_Column opcodes so as to take advantage of this. Leaf check-in: c1adf959 user: dan tags: sort-column-opcodes
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

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

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
01:43
Enable the ".wheretrace" and ".selecttrace" extensions in the command-line shell when compiled on Windows using DEBUG=3 or higher. Fix a harmless warning in the shell that comes up when compiled this way. check-in: 8a03be1d user: drh tags: trunk
2017-02-16
21:29

20:52
Change the name of WhereInfo.pDistinctSet to pResultSet, since it is now used for more than just DISTINCT processing. check-in: 9fc5cd50 user: drh tags: trunk
17:18
Change two MallocZero() calls into MallocRaw() to avoid unnecessary memset(). check-in: ff5e733c user: drh tags: trunk

15:11
Remove the CLANG_VERSION macro, since we have learned that version numbers in clang are "marketing" and are inconsistent and unreliable. Builds using clang will still use the GCC_VERSION macro since clang works hard to be gcc compatible. check-in: 8d3f485d user: drh tags: branch-3.17
15:09
