Update a test case in wal2.test that explicitly corrupts a checksum in the wal file to account for the fact that the first byte of said checksum may initially be 0xFF. (check-in: 2b935bde user: dan tags: trunk)
01:49
Take out the special handling of nolock=true in os_win.c and add it to pager.c, so that it works for all VFSes. Add the pPager->noLock boolean for clarity. (check-in: 725c1c14 user: drh tags: win32-none)
01:20
Avoid unnecessary xUnlock operations on temp file. (check-in: 1829c38c user: drh tags: win32-none)
01:13
Add the immutable=TRUE query parameter and SQLITE_IOCAP_IMMUTABLE, either of which prevents locking of the database and omits tests for existance of journal files. (check-in: 71f152c8 user: drh tags: win32-none)

Merge in all recent changes and enhancements from trunk. (check-in: 84243f84 user: drh tags: win32-none)
18:11
Fix a problem in calculating the costs of "OR" scans. (check-in: 9bbca48b user: dan tags: trunk)
15:22
Modify the way the costs of various query plans are estimated. If the user supplies a likelihood() value (or equivalent) on an indexed WHERE constraint, use it to estimate the number of index rows visited. (check-in: 90e36676 user: dan tags: trunk)
15:00
Add text to the header comment of whereLoopAddBtree() describing how the costs of various b-tree loops are estimated. (Closed-Leaf check-in: 05e6e16c user: dan tags: experimental-costs)
14:53
Update a couple of test cases to account for the fact that this branch prefers an index scan and partial sort over a full-table scan and full external sort. (check-in: 9b975bf3 user: dan tags: experimental-costs)
14:47
Fix a couple of out-of-date comments in where.c. (check-in: eefeda32 user: dan tags: experimental-costs)

19:34
The trunk assumes that an open range constraint on an indexed term (col>?) term matches 1/4 of the indexed rows, and that a closed constraint (col BETWEEN ? AND ?) matches 1/64. Change this branch to do the same. (check-in: 4047ac75 user: dan tags: experimental-costs)
17:56
Add the sqlite3_rtree_query_callback() API to the RTree virtual table. (Cherrypick from the sessions branch.) (check-in: af2cbe64 user: drh tags: trunk)
17:51
Add the sqlite3_rtree_query_callback() API to the RTree virtual table. (check-in: 3dca2809 user: drh tags: sessions)
15:11
Update unordered.test to take into account for the fact that SQLite now prefers a full-table scan over a non-covering index scan that visits a large percentage of the table rows. (check-in: 20f468df user: dan tags: experimental-costs)
12:08
Add an extra column to a table in analyze9.test to give the planner a little more reason to select an index. (check-in: 1b95544f user: dan tags: experimental-costs)
10:00
Update test script analyze3.test to account for the fact that SQLite now prefers a full-table scan over a non-covering index scan that visits a large percentage of the table rows. (check-in: 35f46a55 user: dan tags: experimental-costs)
09:35
Modify internal function whereLoopAdjustCost() so that it does not prefer a skip-scan over a regular index scan even if the regular scan uses a subset of the WHERE terms used by the skip-scan. (check-in: 88a5758d user: dan tags: experimental-costs)
08:49
Fix an error in estimating of the number of rows visited by a range scan. (check-in: d491de62 user: dan tags: experimental-costs)

17:52
Allow the xfer optimization to proceed if the DEFAULT on the very first column of the two tables is different. This is a refinement of the fix for ticket [f67b41381a]. (check-in: 349f4834 user: drh tags: trunk)
14:07
Avoid transfering records between tables unless the default values for all columns are the same. Fix for [f67b41381a]. (check-in: f8c4c495 user: dan tags: trunk)
2014-04-25
20:22
If the user provides likelihood() data for a WHERE clause term used as part of an index key, have the planner use it when calculating the expected number of rows visited by the loop. (check-in: c51efaa5 user: dan tags: experimental-costs)
17:37
Add test cases to ensure correct operation of joins with a virtual table that include DISTINCT and ORDER BY clauses. Verification for ticket [388d01d4bb8f9]. (check-in: 5ada136f user: drh tags: trunk)

Store values loaded from the stat1 table as logarithmic values in memory. (check-in: 1bd74c49 user: dan tags: experimental-costs)
14:42
Make sure ORDER BY clauses on joins that involve virtual tables and that have a DISTINCT clause work correctly. This is a candidate fix for ticket [388d01d4bb8f9]. Test cases for that ticket will be checked in separately. (check-in: 17113812 user: drh tags: trunk)
12:35
When VDBE_PROFILE is enabled, ignore negative opcode times, which sometimes occur, perhaps due to context swaps. (check-in: 4e88042f user: drh tags: trunk)

Comment tweaks on the test case for the [b75a9ca6b0] bug fix. (check-in: 65d2544a user: drh tags: trunk)
13:21
Avoid discarding an ORDER BY clause in the case where an identical GROUP BY clauses uses an index to group, but not sort, the rows. Fix for [b75a9ca6b0]. (check-in: de9a490f user: dan tags: trunk)
2014-04-18
22:20
Clean up the proper-subset cost adjustment logic to make it more compact and easier to read and so that full branch test coverage is more easily obtained. (check-in: 9a5d38c7 user: drh tags: trunk)
00:49
Add the SQLITE_RUNTIME_BYTEORDER compile-time option to force SQLite to check the processor byte-order at run-time. Add additional compile-time byte order checks for ARM, PPC, and SPARC. (check-in: 2c536387 user: drh tags: trunk)
00:06
Add the SQLITE_TESTCTRL_BYTEORDER test control to interrogate SQLite's notion of the processor byte order and whether the byte order is known at compile-time or determined at run-time. (check-in: 9c696196 user: drh tags: trunk)

Make sure the undocumented sqlite_rename_parent() function does not crash even if it is invoked with NULL arguments. Ticket [264b970c4379fd4b94] (check-in: c6fa8d0d user: drh tags: trunk)
2014-04-13

19:15
Make sure column cache elements are cleared correctly when jumping over code for key generation in a partial index. Fix for ticket [2ea3e9fe6379fc3f6]. (check-in: 3122b836 user: drh tags: trunk)
2014-04-10

Performance improvements when reading large blobs, especially if SQLITE_DIRECT_OVERFLOW_READ is defined. (check-in: 2312eb6a user: drh tags: trunk)
18:20
Merge changes to the query planner that strive to ensure that any index usage that is a proper subset of some other index usage always has a slightly higher cost. (check-in: 683dd379 user: drh tags: trunk)
14:12
Ensure the "PRAGMA journal_mode=WAL" works coming from any other journal_mode with ATTACH-ed databases. (check-in: e54330b4 user: drh tags: trunk)
2014-04-03
16:29
Use OP_Copy instead of OP_SCopy when moving results out of a subquery, to prevent the subquery results from changing out from under the outer query. Fix for ticket [98825a79ce1456]. Problem introduced by check-in [1e64dd782a126f48d78]. (check-in: d5513dfa user: drh tags: trunk)

Remove an unnecessary conditional. (Closed-Leaf check-in: 7473c4df user: drh tags: query-plan-experiments)
19:49
Also make sure an index that is a proper subset of some other index has a higher cost than that other index. Add test cases. (check-in: b7830d23 user: drh tags: query-plan-experiments)
18:24
Make sure that an index that covers a proper superset of the WHERE clause terms of some other index has a lower cost than the other index. (check-in: ea8b0910 user: drh tags: query-plan-experiments)
13:42
Avoid a (harmless) buffer overread that is possible on an OOM when MEMSYS5 is engaged. (check-in: b3296267 user: drh tags: trunk)
2014-03-29
21:16
Experiments in picking better query plans, especially when the usage of one index is a subset of another. (check-in: 8f869ca7 user: drh tags: query-plan-experiments)
2014-03-28
14:41
Disable the wal64k.test script for non-unix systems since it depends on unix-only features. (check-in: 27deb6e4 user: drh tags: trunk)
12:56
Fix a harmless compiler warning. (check-in: a4e47150 user: drh tags: trunk)
03:12
Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter database corruption, they will set the UnpackedRecord.isCorrupt field and return 0. The sqlite3BtreeMovetoUnpacked() routine detects this and returns SQLITE_CORRUPT, causing the corruption to be reported back to the top-level. (check-in: 7fa85eaa user: drh tags: trunk)
2014-03-27
18:36
Minor cleanup of the code in the query planner that computes the costs estimates for the various plans. There are no changes to the costs at this time. But the code is slightly more readable now and that might facilitate future enhancements. (check-in: 9b4d7226 user: drh tags: trunk)
14:05
Enhance the logest.c utility with new operators: "dup", "inv", "log", and "nlogn". Provide help on an invalid input. (check-in: b4bd2a06 user: drh tags: trunk)
2014-03-26
