20:04
Improved auto-detection of EXPLAIN output in the shell. (Closed-Leaf check-in: 6c6d7a6e user: drh tags: auto-explain)

Merge latest trunk changes with this branch. (check-in: 1a4182ee user: dan tags: schemalint)
02:12
Make sure every co-routines has its own set of temporary registers and does not share temporaries, since a co-routine might expect the content of a temporary register to be preserved across an OP_Yield. Proposed fix for ticket [d06a25c84454a]. (check-in: ca72be86 user: drh tags: trunk)
2016-02-08

Add code to get the tokenizer character-class logic working for EBCDIC. (Closed-Leaf check-in: 04f7da77 user: drh tags: tokenizer-char-class)
03:23
Faster keywordCode() implementation by taking advantage of the fact that the input is always pure ASCII alphabetic and underscore and that the keyword table is always upper-case. (check-in: ff406b97 user: drh tags: tokenizer-char-class)
02:30
Demonstrate a much faster sqlite3GetToken() routine by using a lookup table to map initial token characters into a character class. This check-in does not work for EBCDIC. More optimization needed. (check-in: 9115baa1 user: drh tags: tokenizer-char-class)
2016-02-07
20:39
Fix harmless compiler warning in 'srcck1' tool and add it to the clean targets. (check-in: 852a529a user: mistachkin tags: trunk)

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: d8b7b199 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: 7453790c 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: 6d7d4703 user: drh tags: trunk)
20:12
Improve performance of fts5 queries. (check-in: 2334e882 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: 4c9222f7 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: 5d7c0928 user: dan tags: trunk)

15:52

02:10
Make use of covering indexes in the OR optimization. (check-in: 9de3d712 user: drh tags: trunk)

2016-01-29
21:16

18:04
Prepend "rc!=SQLITE_OK || " to the nExtraDelete assert() condition. (check-in: 2a055ed0 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: ab946039 user: drh tags: OR-clause-improvement)
08:38
Avoid two more instances of pointer arithmetic on freed pointers. (check-in: 2910ef64 user: dan tags: trunk)
2016-01-28
18:22
Modify the order of terms in an "if" condition to avoid implicitly comparing a dangling pointer to NULL following an OOM error. (check-in: 5372f800 user: dan tags: trunk)

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: dde1db0d user: drh tags: fordelete-assert)
07:28
