Backport check-in [62678be3df35cd]: When the same index is used for all OR-terms in a WHERE clause, then try to use that index as a covering index. Leaf check-in: 865dfcba user: drh tags: branch-3.7.2

Cherrypick the [3513bf6ee090d9] so that the sqlite_source_id() function works correctly even with newer versions of Fossil check-in: 89d63a0e user: drh tags: branch-3.7.2
20:36
Cherrypick changes [53f5cfe115] and [1f7ef0af8d] in order to fix an issue with DISTINCT check-in: 14bc58ca user: drh tags: branch-3.7.2
2011-08-26
18:04
Merge the branch-3.7.2 changes into the stat3-3.7.2 subbranch. Also fix some test script issues. check-in: a42db19d user: drh tags: stat3-3.7.2
17:17
Cherrypick the recursion fix to test_vfs.c from [065e5a5ea4f82]. Also fix the nan.test module to handle upper/lower case changes in TCL. check-in: 41b5f869 user: drh tags: branch-3.7.2
13:52
Merge branches branch-3.7.2 and stat3-enhancement into a new branch for testing purposes. check-in: 0df04f92 user: drh tags: stat3-3.7.2
2011-07-13
18:53
Cherrypicked from trunk: Do not try to use STAT2 for row estimates if the index is unique or nearly so. check-in: d55b64ef user: drh tags: branch-3.7.2

14:48
Cherrypick change [9f14fa56ba] (the fix for [54844eea3f]) from the trunk. check-in: 7afb2354 user: dan tags: branch-3.7.2

Cherrypick change [27c65d4d9c] into the 3.7.2 branch. check-in: 9bbcd8c0 user: dan tags: branch-3.7.2

Cherrypick [45e581bff7] into the 3.7.2 branch. check-in: c593792c user: dan tags: branch-3.7.2

Backport check-ins [0900e35348f4b9bf3] and [4fead8e714c7e50] to the 3.7.2 branch. These check-ins provide hints to the btree layer for when it is possible to use a hash table rather than a btree to implement an index. The SQLite BTree layer does not use these hints, but alternative btree layers might. check-in: 7155e6f3 user: drh tags: branch-3.7.2

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
2011-04-09
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
01:59
This is the beginning of an attempt to backport recent query planner enhancements to version 3.7.2. The code in this version builds and runs and seems to give correct answers, but it generates suboptimal query plans and hence many of the test cases fail. The test script gives up after 1000 errors. check-in: e72cf118 user: drh tags: branch-3.7.2
