[7c6fbcfe6e] Leaf: Clean up the IN operator code generation logic to make it easier to reason about. In the process, improve code generation to omit some unused OP_Null operations. (user: drh, tags: trunk)
15:34
[e13175d357] Closed-Leaf: The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple. (user: drh, tags: IN-operator-improvements)
14:46
[ee0fd6aaf9] Begin making changes to the IN operator in an attempt to make it run faster and to make the code easier to understand. (user: drh, tags: IN-operator-improvements)

19:41
[4cc048c365] Add hidden column "rank". Currently this always returns the same value as the bm25() function. (user: dan, tags: fts5)

2014-07-23
23:57

19:37
[30033f9650] Ugh. Consecutive UNIQUE index entries are only distinct if the index is on NOT NULL columns. So the previous version was not quite right. This check-in fixes the problem. (user: drh, tags: faster-analyze)

13:40
[6c6f0de59b] Change the hex literal processing so that only the SQL parser understands hex literals. Casting and coercing string literals into numeric values does not understand hexadecimal integers.

20:02
[77f412caf0] Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes a no-op if the cursor is already open on the same index.

19:14
[eed754fe93] The optimization of check-in b67a6e33f2 does not work (it generates incorrect VDBE code) if an OR term is AND-ed with a constant expression. So back that optimization out and add a test case to make sure it does not get added back in. (user: drh, tags: trunk)

15:44

16:41

15:01
[b0b4c776c3] Add the ".eqp" dot-command to the ".help" output in the command-line shell. This was accidently omitted when the ".eqp" command was originally implemented for SQLite 3.8.4 (check-in e6ecf7337658624). (user: drh, tags: trunk)

20:24
[10707d3578] Enhance the unix VFS so that it keeps track of the size of unlinked files internally and thus avoids the need to call fstat() on those files, since fstat() does not work reliably on unlinked files on some implementations of FuseFS. (user: drh, tags: trunk)
20:06
[c41df393c6] Closed-Leaf: Enhance the unix VFS so that it keeps track of the size of unlinked files internally and thus avoids the need to call fstat() on those files, since fstat() does not work reliably on unlinked files on some implementations of FuseFS.

13:11
[1925f3a0a2] Modify the %nonassoc directive in lemon so that it generates a run-time error rather than a parsing conflict. This changes is due to a bug report on the mailing list.

2014-06-06
20:49

20:20
[75437bee49] Make sure the estLog() routine in the query planner handles negative values correctly (always returning 1). Prior to this change, estLog(-1) would return a large number which could throw off the cost computations in the query planner in obscure circumstances. (user: drh, tags: trunk)
17:09
