12 check-ins using file src/analyze.c version 0a58e3d8

2012-08-25
00:49
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
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)

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)
2011-07-12
14:48
Cherrypick change [9f14fa56ba] (the fix for [54844eea3f]) from the trunk. (check-in: 7afb2354 user: dan tags: branch-3.7.2)
2011-07-02
15:42
Cherrypick change [27c65d4d9c] into the 3.7.2 branch. (check-in: 9bbcd8c0 user: dan tags: branch-3.7.2)
13:34
Cherrypick [45e581bff7] into the 3.7.2 branch. (check-in: c593792c user: dan tags: branch-3.7.2)
2011-05-01
22:57
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)
2011-04-15
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)
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)
2011-03-29
15:00
If the keyword "unordered" appears at the end of the SQLITE_STAT1.STAT column for an index, then use that index for equality lookups only, never for range queries or sorting. (Closed-Leaf check-in: 3b964155 user: drh tags: unordered-index-hack)
