22:33
Update a shell test case. check-in: b84008cb user: mistachkin tags: asciiMode

2014-07-23
23:57
Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. check-in: 729ece40 user: drh tags: trunk
19:37
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. check-in: 30033f96 user: drh tags: faster-analyze
19:31
Add a snippet() function to fts5. check-in: bdc58fd2 user: dan tags: fts5

15:51
Updated documentation on sqlite3_temp_directory. No changes to code. check-in: e6225a7b user: drh tags: trunk
14:52
Remove a surplus function prototype. #ifdef code that is not used when hex integers are omitted at compile time. check-in: a5b383e0 user: drh tags: hex-literal
13:40
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. This preserves backwards compatibility. Also: Throw an error on any hex literal that is too big to fit into 64 bits. check-in: 6c6f0de5 user: drh tags: hex-literal
02:07
Casting hex literals directly from string to float always results in a positive number. check-in: 4b86ccdf user: drh tags: hex-literal

2014-07-22
22:46
When running ANALYZE, it is not necessary to check the right-most key column for changes since that column will always change if none of the previous columns have. check-in: 48f40861 user: drh tags: trunk
20:02
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. Update the OR-optimization logic to make use of OP_ReopenIdx in order to avoid unnecessary cursor open requests sent to the B-Tree layer. check-in: 77f412ca user: drh tags: trunk
19:14
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. check-in: eed754fe user: drh tags: trunk
16:00
Fix the index name for the shadow tables in the spellfix1 extension so that multiple instances of the spellfix1 virtual table can each have their own index. check-in: 438c348a user: drh tags: trunk
15:33
Correction: The maximum SQLITE_MAX_ATTACHED value to avoid overflowing a signed 8-bit integer is 125, not 127. check-in: 48e37802 user: drh tags: trunk
14:58
Enhance the sqlite_stat1.stat parsing to allow additional text parameters at the end. Unrecognized parameters are silently ignored. check-in: ca2a5a2c user: drh tags: trunk
14:42
Expire prepared statements after running ANALYZE. check-in: b083a961 user: drh tags: trunk
12:05
Enhance the comment on whereLoopAddBtree(). No changes to code. check-in: b22dd165 user: drh tags: trunk
00:40
For the OR-optimization, avoid generating OP_OpenRead opcodes that reopen exactly the same index. check-in: b67a6e33 user: drh tags: trunk
2014-07-21
20:07
Limit the maximum SQLITE_MAX_ATTACHED to 127, since a signed character is sometimes used to store the database index. check-in: f1c76c7c user: drh tags: trunk
15:45
Fix DELETE and UPDATE operations on fts5 tables. check-in: d44d3a85 user: dan tags: fts5
15:44

17:57
Update the sqlite3_stmt_busy() function so that it correctly returns true for "ROLLBACK" statements that have been stepped but not yet reset. check-in: 61cee3c0 user: dan tags: trunk
17:49

Improved documentation for checkpoints and the busy handler. No changes to code. check-in: ca92c024 user: drh tags: trunk
17:39
SQLite has long accepted some unadvertised and non-standard join syntax. Add a test to ensure that future versions continue to accept this non-standard syntax, to avoid breaking legacy applications that use the undefined syntax. check-in: 824dde7f user: drh tags: trunk
14:43
Improvements to the ".fullschema" command in the command-line shell. check-in: fa80c64c user: drh tags: trunk

2014-07-14
19:04
In the expression passed to sqlite3BtreeCursorHint() for the inner loops of joins, replace any TK_COLUMN references to columns in the outer loops with TK_REGISTER expressions (Expr.iTable indicates the specific register containing the value). There are no automated tests for this yet. check-in: f9dddd00 user: dan tags: cursor-hints
2014-07-10
20:21
