Remove the BtreeMutexArray object - use the Vdbe.btreeMask field to accomplish the same result. Add a generation counter to btree mutexes in order to assert that mutexes are never temporarily dropped over a range of instructions in order to do deadlock avoidance in some subroutine. Lock all btrees in any Vdbe program that uses OP_ParseSchema. (check-in: d81708f7 user: drh tags: trunk)

17:53
Change analyze7.test so that it works without SQLITE_ENABLE_STAT2 defined. (check-in: 9415201c user: dan tags: trunk)
16:50
When simulating an error in the close() system call, close the file descriptor anyway. Otherwise long running tests leak too many file-descriptors and crash. (check-in: 81ddbf43 user: dan tags: trunk)

The first simple test-case appears to be working now. (check-in: dd41155b user: drh tags: word-fuzzer)
15:40
Fix a problem whereby following an IO error in CommitPhaseTwo() of a multi-file transaction the b-tree layer could be left in TRANS_WRITE state, causing problems later on. (check-in: dbe569a0 user: dan tags: trunk)
14:08
Further improvements to the fuzzer. It still is not quite working. Pausing to work on other things.... (check-in: 5f2f2fce user: drh tags: word-fuzzer)
10:04

Fix problem with tableapi.test on Windows. (check-in: 69fe0c87 user: shaneh tags: trunk)
01:34
The changes to fix [f7b4edece25c9948] mean that the schema is always loaded whenever a prepared statement is running. This means that a couple of branches can be eliminated and one operand of OP_ParseSchema can be removed. (check-in: b6e268fc user: drh tags: trunk)
2011-03-23
22:54

01:58
Comment enhancement to better explain the logic in the "x IS NULL" optimization. (check-in: 869f8947 user: drh tags: trunk)
01:34

2011-03-16
18:54
Additional interpretation of flags and constants in the VFS trace output. (check-in: 3e984195 user: drh tags: trunk)

2011-03-12
18:10
In the "unix-excl" VFS, use the heap for shared memory, since only a single process is able to read or write the database. (Closed-Leaf check-in: a05a6d40 user: drh tags: unix-excl)
17:02
Add the new optional "unix-excl" VFS. This VFS grabs an exclusive lock on the database preventing other processes from accessing it, but continues to allow other database connections from the same process. (check-in: 00051c32 user: drh tags: unix-excl)
04:58
More tests for SQLITE_OMIT_UNIQUE_ENFORCEMENT and minor change to implementation. (check-in: b8699943 user: shaneh tags: trunk)

Skip unique constraint enforcement if compiled with SQLITE_OMIT_UNIQUE_ENFORCEMENT. (check-in: ba85bf8c user: shaneh tags: trunk)
03:54
Minor clean-up of previous mem5 allocator fix. (check-in: 36438423 user: shaneh tags: trunk)
2011-03-09
21:36
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)
2011-03-08
16:39
Merge the syscall-override changes into trunk. (check-in: 36d79e6f user: drh tags: trunk)
14:05
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)

20:59
Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. (check-in: abf21394 user: drh tags: trunk)
13:54
Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. (check-in: 04abab71 user: drh tags: trunk)
2011-03-04
15:43
Handle EINTR errors from open(). (Closed-Leaf check-in: a7d176b2 user: drh tags: syscall-override)
00:56
Do a better job of choosing the join table order when the tables having very different numbers of rows. (check-in: 952f5e8c user: drh tags: trunk)

17:54
Fix bugs in [7b6e30e6a7] that only show up on Mac. (check-in: ec55e8c6 user: drh tags: trunk)
15:44
Make sure the rtreenode() testing and analysis routine in the RTREE extension can handle 64-bit rowids. This fix is in response to a message on the mailing list. (check-in: 24602557 user: drh tags: trunk)
15:09
Proof-of-concept prototype for the proposed xSetSystemCall extension method on the VFS. (check-in: 92b5a76a user: drh tags: syscall-override)
02:08
Log all error from close() in os_unix.c to sqlite3_log() but do not attempt to report errors back up to the application. Update the unix error logging to put the most important information earlier in the message. (check-in: 7b6e30e6 user: drh tags: trunk)
2011-02-25
03:25
Comment out some code in os_unix.c that only runs on MacOSX with SQLITE_ENABLE_LOCKING_STYLE. (check-in: 4e50b036 user: drh tags: trunk)
