Allow test_bestindex.c to set the omit flag for a constraint. (check-in: 759b9d5b user: dan tags: test-bestindex)
18:07
Add test code useful for testing the planners use of teh virtual table xBestIndex() method. (check-in: de034c0d user: dan tags: test-bestindex)
14:31
Change the estimated row counts in stat1 to be one-third worst-case and two-threads average case. (check-in: 21bfd47c user: drh tags: analyze-worst-case)
12:45
Fix test cases to align with the improved stats computation. (check-in: 810967bf user: drh tags: analyze-worst-case)

23:02
Improvements to the logic for adding the "noskipscan" flag to stat1 entries. (check-in: 421b5b54 user: drh tags: analyze-worst-case)
21:27
The ANALYZE command automatically appends "noskipscan" to sqlite_stat1 entries that have large worst-case repeat estimates but small average repeat estimates. (check-in: 6326ba58 user: drh tags: analyze-worst-case)
20:18
When using a temporary file for a statement journal, store the first 64KiB in memory. If the file grows larger than that, flush it to disk and free the memory. Hardcoding to 64KiB is just an experiment to check that the memjournal.c code works. (check-in: 44b2dc18 user: dan tags: memjournal-exp)
20:00
Fix minor problems with new code in memjournal.c. (check-in: 9fd3f7b9 user: dan tags: memjournal-exp)

13:44
Very minor improvement to the performance and reduction in size to the parser by capturing the name and datatype of table columns in a single grammar rule reduction. (check-in: 4b55c520 user: drh tags: trunk)
13:37
Further simplifications to the grammar. (Closed-Leaf check-in: 519fd03b user: drh tags: schema-storage)
2016-02-27
23:25
Update the parser so that it pulls out the column name and type all in one go, rather than using separate reductions. (check-in: ad3ffe2e user: drh tags: schema-storage)
21:16
Eliminate the need for the Column.zDflt (using Column.pDflt instead) to reduce the amount of memory needed to hold the schema. (check-in: d8c94a46 user: drh tags: trunk)
20:14
Extend the code in memjournal.c so that it subsumes the role of journal.c. And (untested) can flush journal or statement journal files to disk after they grow to a specified size. (check-in: e0b0b431 user: dan tags: memjournal-exp)
19:19
Tighter description of I/O stats in the shell. Show I/O stats on speedtest1.c. (check-in: f681d800 user: drh tags: trunk)

Experimental "PRAGMA onconflict=FAIL" statement to change the default ON CONFLICT algorithm to something other than ABORT. (check-in: 3a0c347c user: drh tags: pragma-onconflict)
17:12
Enhance the ".stats" command in sqlite3.exe to show one-time stats information if invoked with one argument. Also show /proc/PID/io information if run on Linux. (check-in: 3c36948f user: drh tags: trunk)
14:04
Fix a requirement mark to conform to a typo fix in the documentation. (check-in: d1392c62 user: drh tags: trunk)
14:00
Enhance documentation of sqlite3_snapshot_open() to explain that the database connection must have participated in at least one read operation prior to the beginning of the transaction for which the snapshot is to be opened. Add test cases for this fact. (check-in: 33dd671c user: drh tags: trunk)
00:21
Add 'Replace.exe' to the MSVC clean target. (check-in: c2277fab user: mistachkin tags: trunk)

Fix the ICU extension LIKE function so that it does not read past the end of a buffer if it it passed malformed utf-8. (check-in: 424b7aee user: dan tags: trunk)
15:38
Provide the new SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER option to sqlite3_db_config() that can be used to activate the two-argument version of fts3_tokenizer() for a specific database connection at run-time. (check-in: 374b5108 user: drh tags: trunk)
13:22
Fix a typo in a comment (though an important comment in that it is used to generate documentation). (check-in: ff3d7f84 user: drh tags: trunk)
04:13
Ephemeral tables used to hold manifested views may not be unordered since they might be subject to an ordered comparison if they are part of a join. (check-in: 3ef6a315 user: drh tags: trunk)

21:38
Small optimization in FK handling. (check-in: e0d25913 user: mistachkin tags: trunk)

21:19
Change the "PRAGMA stats" command to report size values in LogEst units. The eliminates the need for sqlite3LogEstToInt() unless non-standard compile-time options are used, so leave it out except in those cases. (check-in: 832c237f user: drh tags: trunk)
20:17
Disable the RESTRICT foreign key action if "PRAGMA defer_foreign_keys" is set. (check-in: 9ffff484 user: dan tags: trunk)

Do not use an automatic index on an outer loop that only runs once. (check-in: 5957e793 user: drh tags: planner-improvements)
16:04
Take the LIMIT clause into account when estimating the cost of sorting. (check-in: d491745c user: drh tags: planner-improvements)
13:33
In the command-line shell: When the ".import" command is creating a new table using column names from the first row of CSV input, make sure double-quotes in the name are properly escaped. (check-in: 2e67a1c8 user: drh tags: trunk)
08:02
Improve readability and logging of the vsixtest script. (check-in: 4fe7c4e9 user: mistachkin tags: vsixTest)

Extend [3e9ed1ae] so that covering indexes on WITHOUT ROWID tables are also identified. (check-in: e721975f user: dan tags: trunk)
19:57
Change a char* to const char* in order to suppress some harmless compiler warnings. (check-in: 56f62e34 user: drh tags: trunk)
17:18
When an index completely covers a table, it can be used as a covering index even if columns past the 63rd column are indexed and accessed. (check-in: 3e9ed1ae user: drh tags: trunk)
16:14
Fix a problem with handling identifiers that start with "x" if SQLITE_OMIT_BLOB_LITERAL is defined. (check-in: b65217c6 user: dan tags: trunk)
15:43
Identify indexes that completely cover their table. (Closed-Leaf check-in: 71d488b5 user: drh tags: covering-index)

14:53
Merge the tokenizer buffer overrun bug-fix from trunk. (check-in: 82e7e31b user: drh tags: apple-osx)
14:49
Avoid a potential buffer overrun if an SQL statement being parsed ends with an illegal "!" token. (This problem was detected by fuzzcheck running under valgrind. The problem was introduced by check-in [9570b6b43df3], two days ago and has not appeared in a release.) (check-in: 2a8d97e7 user: drh tags: trunk)
14:03
Improved handling of the -v option on the fuzzcheck test program. (check-in: c8cd7804 user: drh tags: trunk)

2016-02-17
20:47
When VDBE opcodes fail, they cause an immediate exit from the loop, rather than depending on the rc==SQLITE_OK test at the top of the loop. This is faster and smaller. (check-in: 24c7151c user: drh tags: trunk)
18:44
Fix up all VDBE opcodes so that they cause an immediate exit on any kind of error, and thereby eliminate the need to test "rc" at the top of the loop. Resulting code is a little smaller and faster. (Closed-Leaf check-in: a444633a user: drh tags: vdbe-performance)
15:01
Bump the version number to 3.12.0. (check-in: c17d7276 user: drh tags: trunk)
14:48
Remove the "#ifdef SQLITE_TEST" condition from fts5_test_mi.c. Update fts5_main.c so that if SQLITE_FTS5_TEST_MI is defined when it is built the fts5_test_mi.c entry point is automatically called. This makes it easier to build versions of fts5 that include the matchinfo() demo by default. (check-in: 87e6e225 user: dan tags: trunk)
14:11
Improve test coverage of demo code in fts5_test_mi.c. (check-in: 8a78050d user: dan tags: trunk)
