Bug fix in sqlite3SelectDup(). Make sure the pNext pointer is valid. check-in: 7e5b56b1 user: drh tags: tree-explain
01:23
Improvements to the data-structure explain subsystem. Most queries now give a reasonably detailed graph of their parse tree. check-in: 0aa7d3d2 user: drh tags: tree-explain
2011-12-06
19:44
Begin adding the data-structure explaining subsystem. All is contained within check-in: 79ae51c5 user: drh tags: tree-explain
13:46
Add file tkt-3a77c9714e.test, containing tests to verify that the problem documented by ticket [3a77c9714e] has been fixed. check-in: 162421da user: dan tags: trunk
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. Candidate fix for ticket [3a77c9714e63330] check-in: 092d5331 user: drh tags: trunk
00:47
Merge the winGetLastError fixes into trunk. check-in: 5b03ba9d user: drh tags: trunk

Add test logic and some test cases. check-in: a4730586 user: drh tags: quota-stdio
18:44
Add stdio-like I/O interfaces to the test_quota VFS. This is a prototype change for discussion and is mostly untested. This is an alternative to adding stdio-like I/O interfaces in the core. There is no guarantee that this code will make it into the trunk. If it does get to trunk, there could be many changes to the interface first. check-in: bd3ce723 user: drh tags: quota-stdio
02:32
Add a prototype implementation of stdio-like routines for accessing the VFS. This is intended as documentation. The code is untested.

16:23
Remove code made obsolete by the changes to index processing that allow range search on the rowid. check-in: a5418c7f user: drh tags: trunk
15:41
Fix an invalid assert() statement added by [3b58f5f066]. check-in: 888b09dd user: dan tags: trunk

2011-11-13
21:44
Add a version number to the sqlite3_pcache_methods2 object. Other PCACHE2 documentation improvements. Closed-Leaf check-in: 9f839ac0 user: drh tags: experimental-pcache
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

23:51
Catch and report errors from sqlite3OsFullPathname(). check-in: 77119785 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: 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

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
14:23
A negative value N for the cache_size pragma adjusts the number of cache pages to use approximately N kibibytes of memory. check-in: b3faa680 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

16:46
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

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

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

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
