2014-05-08

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
17:19
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: 0deac873 user: drh tags: tkt-55746f9e

Add two new static mutexes, SQLITE_MUTEX_STATIC_APP1 and _APP2, for use by the application program.

20:24
Add #ifdefs for test coverage. Add a testcase(). check-in: be2702ce user: drh tags: trunk
10:19
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

20:32
Merge in all recent changes and enhancements from trunk. check-in: 84243f84 user: drh tags: win32-none

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

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

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

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
