13:24
Do not reuse temp registers originally allocated to a subroutine within the main body of the program logic, since if the subroutine is called while the reused temp registers are in use, their values will get clobbered.

2011-11-12
23:10
Attempt to modify btree.c so that it assumes that calls to sqlite3PagerWrite() will reallocate the page buffer. As there is not good way to test this assumption yet, probably a few spots were missed. (check-in: ceee03c79a user: drh tags: experimental-pcache)
16:46
Remove a couple of incorrect assert statements so that the test suite will run with -DSQLITE_DEFAULT_CACHE_SIZE=0. (check-in: 87614b62ac user: drh tags: trunk)

2011-11-11
23:51
Catch and report errors from sqlite3OsFullPathname(). (check-in: 77119785c8 user: drh tags: trunk)

2011-11-10
21:45
Expand passing of a last error argument to the getLastErrorMsg function. Also, remove unused SQLITE_W32_THREADS define. (check-in: 8f28797984 user: mistachkin tags: trunk)
20:21
In winAccess, save the Win32 last error value prior to invoking user logging callback. Also, explicitly pass the Win32 last error value to winLogError in order to keep it accurate. Fixes a problem reported on the mailing list. (check-in: 32ab365715 user: mistachkin tags: trunk)
02:39
Follow-on to the previous check-in to prevent a division by zero if the lookahead slot size is something goofy like 6 on a 32-bit machine. (check-in: 6bda711f93 user: drh tags: experimental-pcache)
02:24
Use sqlite3MallocSize() to get the actual size of the memory allocation used for lookaside cache and increase the size of the cache to use the full allocation. (check-in: 0e53ecad94 user: drh tags: experimental-pcache)
2011-11-09
18:07
Omit an unnecessary Sleep() call in windows pending-lock retry logic. Enhance the comment on that logic to discourage people from copying it into other VFSes. (check-in: 0c951a9704 user: drh tags: trunk)
17:01
When compiling with MSVC, use the _msize function. (check-in: 797a147934 user: mistachkin tags: experimental-pcache)
16:12
Minor changes needed to restore full branch test coverage. (check-in: bc10a75357 user: drh tags: experimental-pcache)

A negative value N for the cache_size pragma adjusts the number of cache pages to use approximately N kibibytes of memory. (check-in: b3faa680ae user: drh tags: experimental-pcache)
01:53
For the mem1.c system malloc implementation, use the malloc_usable_size() function if the HAVE_MALLOC_USABLE_SIZE macro is defined. Update autoconf to look for that function when configuring. (check-in: 2e8ab3cedf user: drh tags: experimental-pcache)
00:06
Update the API documentation for the new pcache2 interface. Change the order of parameters on the xCreate method of pcache2. (check-in: 4da7095683 user: drh tags: experimental-pcache)

13:05
Change the default file format from 1 to 4. This means that, unless PRAGMA legacy_file_format=ON is used first, new databases will not be readable by versions prior to 3.3.0 (2006-01-10). (check-in: a35f52b1ad user: drh tags: trunk)
2011-11-06
05:06

2011-11-04
14:36
Update the xfer optimization code so that the xfer optimization can be used with INTEGER PRIMARY KEY ON CONFLICT ... as long as the destination table is initially empty. Improvements to the comments on the xfer optimization. New test cases added. (check-in: e3f368cd5e user: drh tags: trunk)
12:05
Change a memcpy() in sqlite3FileSuffix() to memmove() on the grounds that the source and destination may overlap. (check-in: 5e1d247e5b user: dan tags: trunk)

02:24
Use mkdir() and rmdir() rather than open() and unlink() to create the lock files with the unix-dotlock VFS. The change is backwards compatible and, we are told, works better on some network filesystems. (check-in: e2f08426d7 user: drh tags: trunk)
00:35
Enhance the shell so that the ".schema" command works with case insensitive LIKE patterns even with PRAGMA cache_sensitive_like=ON. (check-in: b06bf3b360 user: drh tags: trunk)
00:23
Make sure the INSERT INTO ... SELECT statement works correctly even when the destination table contains an INTEGER PRIMARY KEY ON CONFLICT... column. Ticket [676bc02b87176125]. (check-in: 6f9898db7f user: drh tags: trunk)

2011-10-27
15:19
If an error occurs within sqlite3_step() on a statement prepared using sqlite3_prepare_v2(), transfer both the error code and error message to the database handle before sqlite3_step() returns (so that they are available via sqlite3_errcode() and sqlite3_errmsg(). Prior to this commit, only the error code was transfered. The error message was not available until after either sqlite3_reset() or sqlite3_finalize() had been called on the statement handle. (check-in: 8f88cc4e61 user: dan tags: trunk)
2011-10-22
21:00
Avoid a harmless reference to an uninitialized variable following an error in FTS3. This is not a bug. The change is to silence a valgrind warning. (check-in: d980c5b22f user: drh tags: trunk)
2011-10-21
19:06
Purge lingering references to SQLITE_STAT2 from the code and test scripts. (check-in: aed2bf7a3c user: drh tags: trunk)

Remove stale requirements marks from the query planner. (check-in: 76de9914be user: drh tags: trunk)
14:27
If an error occurs while writing to the database file during a VACUUM, discard the contents of the in-memory cache. This is required as if the database is a zipvfs database, the contents of the cache may be inconsistent with respect to the database as stored on disk. (check-in: 07159e84b4 user: dan tags: trunk)
2011-10-20
18:23
Fix an issue with finding the access permissions of journal files when 8+3 filenames are in use. (check-in: 2b35c5144d user: drh tags: trunk)

16:20
Merge the fts4-content branch with the trunk. (check-in: 8a4077057d user: dan tags: trunk)
15:52
Have FTS3 ignore ^ prefixes. The ^ syntax is only supported on FTS4 tables. (Closed-Leaf check-in: df36ac9481 user: dan tags: fts4-content)
