20:24
Enhance the unix VFS so that it keeps track of the size of unlinked files internally and thus avoids the need to call fstat() on those files, since fstat() does not work reliably on unlinked files on some implementations of FuseFS. (check-in: 10707d35 user: drh tags: trunk)
20:06
Enhance the unix VFS so that it keeps track of the size of unlinked files internally and thus avoids the need to call fstat() on those files, since fstat() does not work reliably on unlinked files on some implementations of FuseFS.

13:11
Modify the %nonassoc directive in lemon so that it generates a run-time error rather than a parsing conflict. This changes is due to a bug report on the mailing list. SQLite does not use the %nonassoc directive in its grammar so this change does not affect SQLite. (check-in: 1925f3a0 user: drh tags: trunk)
2014-06-06
20:49
Add a test case to ensure that estLog() works for negative numbers. (check-in: 813469d9 user: drh tags: trunk)
20:20
Make sure the estLog() routine in the query planner handles negative values correctly (always returning 1). Prior to this change, estLog(-1) would return a large number which could throw off the cost computations in the query planner in obscure circumstances. (check-in: 75437bee user: drh tags: trunk)
17:09
Fix an obsolete comment on the whereRangeScanEst() routine. No changes to code. (check-in: b16bf851 user: drh tags: trunk)

18:27
Fix a problem in the shell when importing CSV files. If the leftmost field of the first row in the CSV file was both zero bytes in size and unquoted, no data was imported. (check-in: 856d44a2 user: dan tags: trunk)
16:40
Fix a problem in FTS4 where columns with names that are prefixes of any notindexed column were also being (incorrectly) marked as not indexed. For example in "CREATE ... t1(abc, bc, abcd, notindexed=abcd)", both abc and abcd were being treated as notindexed. (check-in: d90c4964 user: dan tags: trunk)
2014-05-24
17:15
Remove references in comments to VDBE opcodes that no longer exist. This is a documentation change only; no changes to code. (check-in: ebfb51fe user: drh tags: trunk)
2014-05-23

Changes to the output of EXPLAIN QUERY PLAN to make it clearer when a query uses the PRIMARY KEY index of a WITHOUT ROWID table. (check-in: 9268df30 user: dan tags: trunk)
12:03
In the command-line shell, if three or more interrupt signals (control-c) are received in a row without a response from sqlite3_interrupt() then call exit(1) immediately. This allows control-C to interrupt the shell even if it is stuck in a computation or loop that does not involve the VDBE. (check-in: b5cde571 user: drh tags: trunk)
11:48
Make sure sufficient VDBE registers are allocated for an INSERT...SELECT when there is an idlist on the insert table that includes an explicit rowid. Ticket [e9654505cfda93610585fde5a9bbf2e730c8a8d5] (check-in: 9a2dd187 user: drh tags: trunk)

Make sure the group_concat() function returns an empty string, not a NULL, if it has at least one input row. Fix for ticket [55746f9e65f8587]. (check-in: d01cedaa user: drh tags: trunk)
18:21
Ensure that the sqlite3StrAccumAppend() routine is never called with a NULL second argument. Doing so is harmless when N==0, but it causes an assert() to fail that was placed to quiet static analyzers. (Closed-Leaf check-in: f03fbf37 user: drh tags: tkt-55746f9e)

20:24
Add #ifdefs for test coverage. Add a testcase(). (check-in: be2702ce user: drh tags: trunk)

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

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)

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)
