Add a missing call to "test_sqlite3_log" to multiplex.test. (check-in: 0708f9df user: dan tags: trunk)

Fix a leaked database handle in pager2.test. (check-in: 47457b04 user: dan tags: trunk)

11:57
Add further tests for the extension APIs with "ORDER BY rank" queries. (check-in: 37a417d2 user: dan tags: fts5)

11:54
Have calls to the xFilter() method of rtree virtual tables ensure that cursor is initialized before proceeding. Fix for [d2889096e7bdeac]. (check-in: 8cc41b0b user: dan tags: trunk)

18:57
In vdbesort.c, rename vdbeSorterDoCompare() to vdbeMergeEngineCompare() and move it closer to the one place where it is called. Other minor comment changes. (check-in: 09d50d9f user: drh tags: threads)
17:18
In vdbesort.c, rename all pointers to sqlite3_file objects "pFd" and use the name "pFile" only for pointers to SortFile objects. Other comment enhancements. (check-in: 518290a7 user: drh tags: threads)
15:01
Merge recent trunk changes into the threads branch. (check-in: 163c247b user: drh tags: threads)

12:09
In the command-line shell, in CSV output mode, terminate rows with CRNL but do not expand NL characters in data into CRNL. Provide the extra -newline command-line option and the extra argument to .separator to designate an alternative newline character sequence for CSV output. (check-in: 16c8ce10 user: drh tags: trunk)
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)

Reformatting a few test cases for clarity. (check-in: 7e1bbacb 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
Allow the SQLITE_MAX_ATTACHED compile-time option to be larger than 62. The default limit on the number of attached databases remains 10. (check-in: 1a817ae2 user: drh tags: trunk)
14:22
Add the xTokenize extension API. (check-in: 8c6b0aff user: dan tags: fts5)

20:15
Add new ASCII mode to the shell capable of importing and exporting using the official unit and record separators (i.e. 0x1F and 0x1E, respectively). (check-in: 7fe601ea user: mistachkin tags: asciiMode)
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
Fix harmless compiler warnings in the showdb and showwal tools and in the unicode tokenizer of FTS3. (check-in: 574cc8eb user: drh tags: trunk)
15:44
Fix some harmess compiler warnings in the FTS3 Unicode module. (Closed-Leaf check-in: c01caea5 user: mistachkin tags: toolWarnings)
15:40
Fix warnings related to having a 64-bit size_t. (check-in: 29ac9336 user: mistachkin tags: toolWarnings)
