2016-02-03
22:14
In the VDBE loop, only check for OOM errors at jumps rather than after every opcode, for about a 0.5% performance increase. (check-in: 632071bac5 user: drh tags: trunk)
20:04
Improve performance of fts5 prefix queries on detail=col tables. (check-in: ca11f46db0 user: dan tags: trunk)
19:52
Fix markup errors in comments used to generate the documentation - specifically in the documentation on the OP_Seek opcode. (check-in: ef252bc4b5 user: drh tags: trunk)
19:20
Add "PRAGMA synchronous=EXTRA" which syncs the directory containing the rollback journal when the rollback journal is deleted in order to commit a transaction in DELETE mode. (check-in: af92401826 user: drh tags: trunk)
01:55
Enhance the internal sqlite3VdbeAddOpList() interface to automatically update jump destinations. Use this feature to simplify the AUTOINCREMENT code generator. (check-in: ae8b9d2edf user: drh tags: trunk)
2016-02-02
21:19
Add tests to restore full coverage of fts5 code. (check-in: 063755c815 user: dan tags: trunk)
17:40
Enhance the performance of fts5 AND and OR queries. (check-in: 62ea9e5ab8 user: dan tags: trunk)
02:53
Merge recent enhancements from trunk. (check-in: 347f6a80c2 user: drh tags: begin-concurrent)

Merge all recent enhancements from trunk. (check-in: f3f9200115 user: drh tags: sessions)
02:04
Enhance the comment on the sqlite3_index_constraint object to bring attention to the fact than iColumn field can be negative for a rowid. (check-in: d8b7b1996e user: drh tags: trunk)
00:59
Add the SQLITE_DBCONFIG_REQUIRE_WRITE_TXN connection setting, which if enabled requires all write operations to be enclosed within BEGIN ... COMMIT. (Leaf check-in: 7453790c3b user: drh tags: require-write-txn)
2016-02-01
21:48
Change the OP_SetCookie instruction to write the literal P3 value, not the value in register P3. (check-in: 6d7d4703eb user: drh tags: trunk)
20:12
Improve performance of fts5 queries. (check-in: 2334e88244 user: dan tags: trunk)
17:20
Number VDBE opcodes starting with 0 instead of 1, as this obviates the lower-bound test on "switch(opcode){...}", making the code smaller and faster. (check-in: 4c9222f75b user: drh tags: trunk)
16:36
Update walcrash.test to ensure that, during a particular test, enough data is written to cause SQLite to sync the wal file 14 times. (check-in: 5d7c092869 user: dan tags: trunk)
13:58
Fix a problem causing the OR/covering-index optimization to be disabled if compile time parameter SQLITE_MAX_ATTACHED were set to greater than 30. (check-in: a17712bf8d user: dan tags: trunk)
13:21
Minor simplification to the OP_AutoCommit opcode. Fix some code comments related to transaction control. (check-in: a9b6a0672f user: drh tags: trunk)
00:21
Fix an assert() that might fail on a corrupt database. (check-in: 22eaced727 user: drh tags: trunk)
2016-01-30
21:09
Fix new test cases in stat.test so that they work with -DSQLITE_DEFAULT_AUTOVACUUM=1 builds. (check-in: a2810cf65d user: dan tags: trunk)
19:16
Performance enhancement for fts5 column filter queries on detail=full tables. (check-in: 13fb4aa6a8 user: dan tags: trunk)
16:59
Merge the implementation of OP_IdxRowid and OP_Seek so that OP_Seek no longer requires the rowid register and a separate OP_IdxRowid call. Shorter and faster prepared statements result. (check-in: 9bec50a1e7 user: drh tags: trunk)
15:52
Only honor the register subtype value if the MEM_Subtype flag is set. Revised and improved fix for ticket [f45ac567eaa9f9]. (check-in: 1f4c667f37 user: drh tags: trunk)
15:46
A different way to clear the subtype on VDBE registers when the value of the register is overwritten with new content. To fix [[f45ac567eaa9f93]. (Closed-Leaf check-in: 2e9fb1295c user: dan tags: clear-subtype-flag)
14:53
Take care to clear the subtype on VDBE registers when the value of the register is overwritten with new content. (Closed-Leaf check-in: ec653cbcae user: drh tags: clear-subtype-fail)
14:17
Output subtype information on register traces for PRAGMA vdbe_trace. (check-in: 96b780209c user: drh tags: trunk)
13:32
Add the BTREE_FORDELETE and BTREE_AUXDELETE flags to the b-tree layer interface and use them. Add assert() statement to verify that they are correct. (check-in: 85c467041c user: drh tags: trunk)
12:50
Simplification and size reduction to the printf logic. Remove the bFlags parameter from sqlite3VXPrintf() and sqlite3XPrintf(). Use sqlite3XPrintf() instead of sqlite3_snprintf() for rendering P4 values in EXPLAIN output. (check-in: 0bdb41c45a user: drh tags: trunk)
02:10
Make use of covering indexes in the OR optimization. (check-in: 9de3d71230 user: drh tags: trunk)
00:45
Change the P4_INTARRAY so that always begins with a length integer. Print the content of the INTARRAY on EXPLAIN output. (Closed-Leaf check-in: 6c520d5726 user: drh tags: covering-or)
2016-01-29
21:16

Remove a stray "exit" in a test script. (Closed-Leaf check-in: 10c88bf9f2 user: drh tags: fordelete-assert)
18:11
Avoid unnecessary WHERE clause term tests when coding a join where one of the tables contains a OR constraint. (check-in: 512caa1ad3 user: drh tags: trunk)
18:04
Prepend "rc!=SQLITE_OK || " to the nExtraDelete assert() condition. (check-in: 2a055ed0af user: dan tags: fordelete-assert)
16:57
Avoid unnecessary WHERE clause term tests when coding a join where one of the tables contains a OR constraint. (Closed-Leaf check-in: ab94603974 user: drh tags: OR-clause-improvement)
08:38
Avoid two more instances of pointer arithmetic on freed pointers. (check-in: 2910ef6409 user: dan tags: trunk)
2016-01-28
18:22

2016-01-27
23:50
Make the MSVC batch build tool sub-routine 'fn_UnsetVariable' a bit more robust. (check-in: 1edd5f31b9 user: mistachkin tags: trunk)
16:26
Change the name of the BTREE_IDXDELETE flag to BTREE_AUXDELETE, to better reflect its purpose. (check-in: 1d3bf6bebd user: drh tags: fordelete-assert)
16:17
Fix tests in fordelete.test to test for the BTREE_AUXDELETE flag. (check-in: bbd25cf179 user: dan tags: fordelete-assert)
15:49
Add assert() statements on the nExtraDelete variable in vdbe.c to try to verify that the FORDELETE and IDXDELETE flags are being generated correctly. Those flags are not currently generated correctly, and so the assert()s trip on this check-in. (check-in: dde1db0dd2 user: drh tags: fordelete-assert)
07:28
