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: ceee03c7 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: 87614b62 user: drh tags: trunk)
15:41
Merge the windows xSyscall enhancements into trunk. (check-in: c1fab9ac user: drh tags: trunk)

Make sure to flag benign malloc failures in the Windows VFS as such. Expand use of the DO_OS_MALLOC_TEST to cover the VFS functions that can now return an out of memory error. Support an experimental --match option to the test suite that will run only those tests matching the specified pattern. (Closed-Leaf check-in: 76dec8aa user: mistachkin tags: winSyscall)
2011-11-11
23:51
Catch and report errors from sqlite3OsFullPathname(). (check-in: 77119785 user: drh tags: trunk)

22:08
Work in progress to implement the 'syscall' functionality for Windows. (check-in: ed88fb00 user: mistachkin tags: winSyscall)

Pull over all the latest changes from trunk. (check-in: 1bbbf857 user: drh tags: experimental-pcache)

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: 8f287979 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: 32ab3657 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: 6bda711f 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: 0e53ecad 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: 0c951a97 user: drh tags: trunk)
17:01
When compiling with MSVC, use the _msize function. (check-in: 797a1479 user: mistachkin tags: experimental-pcache)
16:12
Minor changes needed to restore full branch test coverage. (check-in: bc10a753 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: 2e8ab3ce 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: 4da70956 user: drh tags: experimental-pcache)
2011-11-08

Add a makefile target for tclsqlite3.c to Makefile.in. (check-in: f521b6b7 user: drh tags: trunk)
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: a35f52b1 user: drh tags: trunk)
2011-11-06
05:06
Move function sqlite3PagerClearCache() out of the "ifndef SQLITE_OMIT_WAL" block and into an "ifndef SQLITE_OMIT_VACUUM" block. (check-in: 5dbfaed8 user: dan tags: trunk)
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: e3f368cd 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: 5e1d247e user: dan tags: trunk)
10:37
Add a missing va_end() macro to fts3.c. (check-in: e6f82574 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: e2f08426 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: b06bf3b3 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: 6f9898db user: drh tags: trunk)
2011-11-01

06:52
Update fts3fault.test to account for the sqlite3_errmsg() related changes in [8f88cc4e61] and [dcb7879347]. (check-in: 3f2d49c6 user: dan tags: trunk)
2011-10-29

15:29
Add a test for [48f29963] that does not depend on FTS. (check-in: fb15f545 user: dan tags: trunk)

01:33
Avoid reporting a NOMEM error if a memory allocation fails while copying the error message from a prepared statement into the database connection. (check-in: dcb78793 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: 8f88cc4e 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: d980c5b2 user: drh tags: trunk)
2011-10-21
19:06
Purge lingering references to SQLITE_STAT2 from the code and test scripts. (check-in: aed2bf7a user: drh tags: trunk)
16:47
Remove stale requirements marks from the query planner. (check-in: 76de9914 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: 07159e84 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: 2b35c514 user: drh tags: trunk)
