2011-03-17
16:45
Update the implementation of ".testctrl" in the command-line shell to use a look-up table rather than a long sequence of if-elses. Shorten source code lines of shell.c to 80 characters or less. (check-in: 54bacb95 user: drh tags: trunk)
01:58

01:34
Enhances to the query planner such that "x IS NULL" constraints take the STAT2 statistics into account, just like "x=VALUE" constraints. (check-in: 23531768 user: drh tags: trunk)
2011-03-16
18:54
Additional interpretation of flags and constants in the VFS trace output. (check-in: 3e984195 user: drh tags: trunk)

2011-03-15
19:08
Make the "unix-excl" VFS work exactly like "unix" if the database file is read-only. (check-in: d9846834 user: drh tags: trunk)
18:35
Fix an out-of-order variable declaration in shell.c. (check-in: 72570846 user: drh tags: trunk)

02:55
Fix cut-and-paste typo in debugging print statement in winMutexTry(). (check-in: def98fd2 user: shaneh tags: trunk)

Fix issue with mem5 allocator when min request size is larger thatn 2^30. (check-in: d7dae06f user: shaneh tags: trunk)
21:02
Omit unnecessary OP_Next and OP_Prev operators when uniqueness constraints guarantee that the code will only make one pass through the loop. (check-in: f000c9b2 user: drh tags: trunk)
11:04
Updates to the OS/2 implementation from Rich Walsh. (check-in: dc46156a user: drh tags: trunk)

16:39
Merge the syscall-override changes into trunk. (check-in: 36d79e6f user: drh tags: trunk)

Unix errno integer can vary from one system to the next. So do not depend on specific errno values in test cases. (check-in: ddb747d3 user: drh tags: trunk)
13:06
Fix two compiler warnings. No functional code changes. (check-in: c829868a user: drh tags: trunk)
