15:18
Backport check-in [9f9f32882501ac9] to provide EXPLAIN QUERY PLAN output for the count(*) optimization. Also backport check-in [a8761a9128de945aa] to prevent unordered indices from being used on a full table scan. The first backport was necessary in order to test the second. (check-in: 8d924e16 user: drh tags: branch-3.7.2)

03:30
Back port the unordered-index-hack to the 3.7.2 branch. (check-in: 80353020 user: drh tags: branch-3.7.2)
2011-04-08
23:36
Backport test cases from trunk that seek to prove that the IS NOT NULL query optimization is working. (check-in: 9eff4702 user: drh tags: branch-3.7.2)
23:05
Make sure the query planner is able to correctly analyze NULL value samples in the sqlite_stat2 table. This is a backport of changes from check-in [f73a167b434f] (check-in: 1d637889 user: drh tags: branch-3.7.2)
23:04
Make sure the left-hand side of the IS NOT NULL operator is a simple column and not a general expression before applying the IS NOT NULL optimization. This is a backport of check-in [543f75a6abe3]. (check-in: e8177e01 user: drh tags: branch-3.7.2)
2011-03-31
18:36
Provide hints to the btree layer Next and Previous primitives to let them know if they can be no-ops if the underlying index is unique. (check-in: a5aae174 user: drh tags: branch-3.7.2)
2011-03-17
01:53
Backport the "x IS NULL" query planner enhancement of [2353176811f] to the 3.7.2 branch. (check-in: 68daf20d user: drh tags: branch-3.7.2)
2011-03-12
05:55
Backport the SQLITE_OMIT_UNIQUE_ENFORCEMENT change from check-in [b86999436e] on the trunk. (check-in: 668b91db user: shaneh tags: branch-3.7.2)
2011-03-09
22:09
Backport the OP_Next and OP_Prev for UNIQUE indices patch from checkin [f000c9b2b7] on the trunk. (check-in: 2d55234e user: drh tags: branch-3.7.2)
2011-03-04
01:23
Backport the query planner enhancement of [952f5e8c69904] to the 3.7.2 branch. (check-in: 440d9956 user: drh tags: branch-3.7.2)
2011-02-12
14:23
Fix the expected output on tests so that it corresponds to the new query planner results. All of veryquick.test is now passing with SQLITE_ENABLE_STAT2. (check-in: f2a8b5cc user: drh tags: branch-3.7.2)
05:34
Fix problems in the backport, reducing the number of errors in the TCL tests to just a few dozen. Most of the remaining errors seem to be real and desirable changes of behavior. (check-in: 9d2b0af2 user: drh tags: branch-3.7.2)
