[f8105085] Leaf: Prevent the WhereLoop.rSetup cost estimate from going negative on complex queries. (user: drh, tags: trunk)
2016-06-25
11:43
[507014e4] Fix the handling of OP_Eq opcodes that compare a register against itself and that require an affinity change. (user: drh, tags: trunk)

[77e4f7a3] Fix the ctime.test script so that it works with clang. (user: drh, tags: trunk)

[67c39e16] Fix the Makefile.in to avoid unnecessary recompiles of sqlite3.c. (user: drh, tags: trunk)
2016-06-23
16:48
[b8671e94] Update the sqldiff utility so that if the --vtab switch is specified "rtree", "fts3", "fts4" and "fts5" tables are diff'd directly and the underlying real database tables ignored. Without this switch, all virtual tables are ignored and the diff is performed on the underlying real tables. (user: dan, tags: trunk)
12:35
[91113142] Fix the build for -DSQLITE_OMIT_VIRTUALTABLE (user: drh, tags: trunk)

[5d0a9d4c] Closed-Leaf: Update the sqldiff utility so that if the --vtab switch is specified "rtree", "fts3", "fts4" and "fts5" tables are diff'd directly and the underlying real database tables ignored. Without this switch, all virtual tables are ignored and the diff is performed on the underlying real tables. (user: dan, tags: sqldiff-vtab-support)

[913e5956] For a table on the rhs of a LEFT JOIN operator, do not include terms like "IS NULL" from the WHERE clause in the cursor-hint. These may be false for rows that the cursor would otherwise visit, but true for a row of all NULL values generated by the LEFT JOIN. (user: dan, tags: trunk)
17:22
[7455d932] Closed-Leaf: Allow LIKE operators that appear in a WHERE clause to be included in the cursor-hint for a cursor on the rhs of a LEFT JOIN. (user: dan, tags: cursor-hints)
2016-06-17
19:27
[998095ab] Include WHERE terms in the cursor-hint passed to a cursor opened for the rhs of a LEFT JOIN iff we can be sure that those terms will not evaluate to true if the LEFT JOIN generates a row of NULLs. (user: dan, tags: cursor-hints)
14:59
[fcd12b69] Fix a duplicate test name in cursorhint2.test. (user: dan, tags: cursor-hints)
14:47
[c1a5a57c] Fix a typo in the cursorhint2.test script. (user: dan, tags: cursor-hints)
14:33
[2a2346b0] If a table is on the rhs of a LEFT JOIN, include only terms from the joins ON(...) clause in the cursor-hint passed via OP_CursorHint. (user: dan, tags: cursor-hints)
2016-06-16

[0b1579ca] Add a missing OP_ColumnsUsed opcode to code for expressions like "? IN (SELECT ...)" in cases where expression can use an index that may contain NULL values. (user: dan, tags: trunk)
11:16
[48b555c4] Fix a typo in a comment on the SrcList object. (user: drh, tags: trunk)
2016-06-13

[0230ca17] Fix RBU so that it builds with -DSQLITE_ENABLE_8_3_NAMES. Fix "PRAGMA compile_options" for SQLITE_ENABLE_8_3_NAMES such that it reports the numeric setting: "1" or "2". (user: drh, tags: trunk)
15:59
[a1e1cdc5] Fix the declaration of the table implemented by DBSTAT so that it uses correct datatypes. (user: drh, tags: trunk)
12:51
[fcf6114b] Fix an incorrect assert() in the btree logic. (user: drh, tags: trunk)
12:34
[d362ba15] Fix the "onecolumn" and "exists" methods of the TCL interface so that they work in combination with the "profile" callback. (user: drh, tags: trunk)
2016-06-10
22:49
[53a1e5d5] Enhance "PRAGMA table_info" to that it provides information about eponymous virtual tables. (user: drh, tags: trunk)
2016-06-08
18:07
[fe187432] Prefer to use partial indexes for full table scans when that is possible. (user: drh, tags: trunk)
14:04
[f48a4ad3] Add the "dbhash.exe" utility program that computes a SHA1 hash over the invariant content of an SQLite database file. Free space in the file, the page size, auto_vacuum status, text encoding, and so forth do not change the hash. Only the content matters. (user: drh, tags: trunk)
13:59
[fb276815] Closed-Leaf: Fix an undersized buffer in the SHA1 implementation. (user: drh, tags: dbhash)
13:49
[44f157e0] Fix the dbhash utility so that it ignores the root page number when hashing the sqlite_master table. Add new command-line options. Add the ability to hash multiple databases with a single command. (user: drh, tags: dbhash)
01:03
[2247649c] An initial attempt at a "dbhash" command-line utility. (user: drh, tags: dbhash)

[e404ad70] In winFullPathname, translate '/X:' to 'X:' before doing anything else. (user: mistachkin, tags: trunk)
20:27
[f8470ffc] Translate filenames of the form "/c:/*" into just "c:/*" on WinRT and Cygwin. (SQLite has long done this for Win32/WinNT.) (user: drh, tags: trunk)
18:17
[3665a2f5] Fix lempar.c so that the shift-reduce optimization works for error processing. This is a Lemon issue only and has no impact on SQLite. (user: drh, tags: trunk)
13:24
[45531654] Initialize the yyerrcnt variable in the lemon parser template. This has no effect on SQLite itself. (user: drh, tags: trunk)
01:54
[e106a77d] Small performance boost and size decrease in sqlite3BtreeMovetoUnpacked(). (user: drh, tags: trunk)
