The robust_flock() fix that accidently included some unrelated, though harmless changes. I should follow my own checklist! (Closed-Leaf check-in: e701efbd1d user: drh tags: mistake)
13:33
Retry selected system calls on unix when they fail with EINTR. (check-in: b9d29ea385 user: drh tags: trunk)

03:34
When a stale schema-cookie is seen, expire only the one statement that encountered the bad cookie, not every statement on the database connection. Ticket [b72787b1a7cea1f] (check-in: 1bca0a7e19 user: drh tags: trunk)

An SQLITE_PROTOCOL error counts as a locking error for verification purposes. (check-in: e87d499a4f user: drh tags: trunk)

2011-02-18
17:23
Fix the sqlite3ValueFromExpr() routine so that it returns SQLITE_NOMEM on an OOM when trying to extract a NULL. (check-in: 1061e94fa9 user: drh tags: trunk)
2011-02-17

2011-02-14
03:49
Skip some tests in capi3e.test when compiled with SQLITE_OMIT_UTF16. (check-in: b04304b967 user: shaneh tags: trunk)
2011-02-11
22:54
Add a NEVER() around a test that is believed to always be false. (check-in: f7e2ea33d5 user: drh tags: trunk)
20:52
Skip flattening if subquery has LIMIT and outer query is DISTINCT. Fix for ticket [752e1646fc]. (check-in: 5597399988 user: shaneh tags: trunk)
06:59
Fix a bug in the new WHERE-clause processing that tries to use an index to resolve IS NOT NULL constraints when SQLITE_ENABLE_STAT2 is defined. The bug could cause memory overruns and segfaults. The bug was new to the code and has not appeared in an official release. Found during structural testing. (check-in: a5c36b9f39 user: drh tags: trunk)
03:56
Allow an index paired with an IS NULL constraint to be used for sorting under the condition that the index be treated as a non-unique index. (check-in: d78949fc93 user: drh tags: trunk)
02:43
Disable unused NULL tests when SQLITE_ENABLE_STAT2 is not in use. (check-in: 5ecd117882 user: drh tags: trunk)
2011-02-10
21:08
Add .testctrl option to CLI. (check-in: f85afa0ecc user: shaneh tags: trunk)
18:56
Split the documentation for sqlite3_wal_checkpoint_v2() and its constants onto separate pages. No changes to code. (check-in: 0ef8ffd12f user: drh tags: trunk)
17:46
Prevent a segfault when automatic indices try to use a column with an unknown collating function. Ticket [77aa3b1e6592582e38605d36]. This check-in also removes some stray \r characters unrelated to the problem. (check-in: f01030a0df user: drh tags: trunk)
00:08
Refactor the cost function in the query planner. Give extra cost (thus reduce likelihood of selection) to full table scans. (check-in: 878da276eb user: drh tags: trunk)
2011-02-09
19:55
Make sure code *compiles* with each OMIT and ENABLE option. Mostly changes to test modules. (check-in: 7cc515edc9 user: shaneh tags: trunk)
18:19
Do not report corruption if the the db size header field is greater than the file size on disk unless the two change-counter header fields are identical. Fix for ticket [89b8c9ac54]. (check-in: 00c4596f0b user: dan tags: trunk)
15:25
Update Makefile.in for fts3_aux changes. (check-in: 38b7cb33c5 user: shaneh tags: trunk)
03:04
Use macros to define the relative costs of search and seek operations when computing costs in the query planner. Current constants seems wrong and need to be fixed, but doing so will alter test results. Need more experimentation to determine accurate relative costs. (check-in: 5f2ec44b22 user: drh tags: trunk)
03:03
Simplifications to the sqlite3_wal_checkpoint_v2() logic. (check-in: 652b8835c5 user: drh tags: trunk)
2011-02-07
23:56
Cleanup to the OP_Checkpoint opcode. (check-in: f611a5a879 user: drh tags: trunk)
16:24
Fix some test cases in walfault.test. Extend one test case to restore code coverage. Add wal5.test to the "coverage-wal" permutation. (check-in: f83b07ace3 user: dan tags: trunk)
15:12
Change blocking-checkpoint tests so that they run once using "PRAGMA wal_checkpoint" and once using calls to sqlite3_wal_checkpoint_v2(). Also fix edge cases surrounding the output variables set by wal_checkpoint_v2(). (check-in: 5a4b6652cf user: dan tags: trunk)
2011-02-05
15:47
Ensure fts4aux can handle a table name in single or double quotes as a constructor argument. (check-in: 929d62e496 user: dan tags: trunk)
14:37
Add test cases for fts4aux. Fix a bug affecting fts3 tables with multiple columns. (check-in: dc511e60a6 user: dan tags: trunk)
2011-02-04
18:56
Change fts4aux to (additionally) report on term frequency in individual columns of an fts table. (check-in: 3996f92a9a user: dan tags: trunk)
14:28
Significant changes have occurred since the 3.7.5 release so go ahead and increase the version number to 3.7.6. (check-in: 999c915a4a user: drh tags: trunk)
06:36
Merge the stat2 query planner enhancements into the trunk. (check-in: 499edcbc8a user: drh tags: trunk)
2011-01-28
03:13
Reactivate the analyze5.test script. (Closed-Leaf check-in: a2a9f6401c user: drh tags: stat2-enhancement)
01:57
Change the weighting of binary searches on tables to 1/10th the cost of a search on an index. Change the assumed reduction in search space from a indexed range constraint from 1/3rd to 1/4th. Do not let the estimated number of rows drop below 1. (check-in: 4847c6cb71 user: drh tags: stat2-enhancement)
2011-01-24
17:46
Restructuring and generalizing analyze5.test. The whole script is currently disabled and will need to be reenabled prior to merging with trunk. (check-in: 31fcc7067b user: drh tags: stat2-enhancement)
15:11
Change the cost estimator in the query planner to take into account the logN rowid lookup cost when going from an index to a table. (check-in: b442525b0b user: drh tags: stat2-enhancement)
2011-01-22
00:10
Add the ability to use indices for constraints of the form "x IS NOT NULL" when sqlite_stat2 is available and most entries for column x are NULL. (check-in: 5d5bddd290 user: drh tags: stat2-enhancement)
2011-01-21
18:18
Adjustments to the result row estimator for the IN operator so that it gives the same estimates as the equivalent OR operator. Test cases for the same. (check-in: c82cb9c028 user: drh tags: stat2-enhancement)
16:27
Make use of histogram data to make better estimates for the number of rows that will be returned from "x IN (v1,v2,v3,...)" constraints. (check-in: fd3977a27a user: drh tags: stat2-enhancement)
14:37
Add the ability to use indices when a range contraint is bounded on the lower end by NULL. (check-in: f73a167b43 user: drh tags: stat2-enhancement)
