17:44
Add stdio support to the quota VFS. check-in: 322bd15f user: drh tags: trunk
17:42
Use _commit() rather than FlushFileBuffers() as a substitute for fsync() on windows. Also cast for C++ and add support for SQLITE_FCNTL_VFSNAME. Closed-Leaf check-in: e85cfe9a user: drh tags: quota-stdio
17:00
When deleting a file with the multiplexor VFS, also delete any overflow files that exist. check-in: 3af1feaa user: dan tags: nx-devkit
13:29
Make sure the chunksize in test_multiplex does not cause the pending byte to fall near the end of a chunk. Adjust the chunksize upward as necessary to prevent this. check-in: e05f8a29 user: drh tags: nx-devkit
11:45
Fix some problems with dropped error codes in multiplexOpen(). check-in: 2d50f781 user: dan tags: nx-devkit
02:22
In the multiplexor, do not try to delete overflow files that do not exist. And assume all but the last overflow file is the size of the chunk size. check-in: a822a80d user: drh tags: nx-devkit
2011-12-14
18:33
Merge the nx-devkit changes into trunk. This includes the new SQLITE_FCNTL_VFSNAME file-control. check-in: da118e02 user: drh tags: trunk
18:28
Merge the VFSNAME file-control addition into the nx-devkit branch. check-in: 08c1dc51 user: drh tags: nx-devkit
17:53
Add a file-control that will discover the name of the bottom-level VFS and all the shims in between. Closed-Leaf check-in: cdbfb553 user: drh tags: vfsname-filectrl
01:38
Improvements to comments. No code changes. check-in: 08bbbd8e user: drh tags: nx-devkit
00:37
Treat a zero return value from the Win32 APIs MultiByteToWideChar and WideCharToMultiByte as an error condition. check-in: c65e5a36 user: mistachkin tags: trunk
00:04
Harden the utf8-to-mbcs converter in the quota module against failures. check-in: 1cda511d user: drh tags: quota-stdio
2011-12-13
23:26
Enhancements to test_quota.c: Remove the external dependency on sqlite3_win32_utf8_to_msbc(). Add an extra parameter to quota_fflush() that will also do an fsync (or the equivalent). check-in: 92f4188f user: drh tags: quota-stdio
19:03
Add a hard limit to the number of chunks a multiplexed database may consist of if ENABLE_8_3_NAMES is defined. check-in: 43a12640 user: dan tags: nx-devkit
18:22
Change the SQLITE_EXTRA_INIT routine to take a single argument which is a pointer to a string. Call SQLITE_EXTRA_INIT with a NULL argument. Fixes to multiplexor to treat the VFS properly in corner cases. Fix the initialization of multiplex3.test. check-in: 8e65b913 user: drh tags: nx-devkit
16:40
Add extra tests for the multiplexor VFS. No changes to code. check-in: c7de6f68 user: dan tags: nx-devkit
15:37
Merge the nx-devkit changes into trunk. check-in: 03a70c3d user: drh tags: trunk
15:25
Update the multiplex.test script to conform to that found in the "experimental" branch off of trunk. check-in: 2eb79efb user: drh tags: nx-devkit
15:02
Move the multiplexor changes in the experimental branch (check-ins [255d21499b] and [199f52bced]) into the nx-devkit branch. check-in: eb95d2f7 user: drh tags: nx-devkit
12:10
This branch merged with nx-devkit and from there into trunk. Was: In the multiplexor, instead of generating a unique file-name when SQLite opens a temp file, allow the underlying VFS to generate a different temp file for each chunk. Given the changes to the xFileSize method, it is no longer necessary for the different chunks of a temp file to use the same base name. Closed-Leaf check-in: 199f52bc user: dan tags: experimental
11:15
Change the way IO errors are handled in the xFileSize method of the multiplexor VFS. Add test file multiplex3.test. check-in: 255d2149 user: dan tags: experimental
04:08
When an sqlite3_auto_extension() function fails, report back its actual error code, not the generic SQLITE_ERROR. check-in: ce55f250 user: drh tags: nx-devkit
02:41
When the multiplexor FileSize procedure fails to open the file, assume that the file is zero bytes in size. check-in: dc8118cd user: drh tags: nx-devkit
01:34
Add a compile-time shutdown procedure to be called by sqlite3_shutdown() to undo the effects of the compile-time initialization procedure. check-in: c2ed86f5 user: drh tags: nx-devkit
2011-12-12
20:01
Backport a minimal set of changes needed to get 8+3 filenames and the multiplexor shim playing well together. check-in: c4e2ce48 user: drh tags: nx-devkit
19:48
Fix os_unix.c so that, unless 8.3 filenames are actually in use, journal and wal file permissions are assigned correctly even if SQLITE_ENABLE_8_3_NAMES is defined. check-in: 169e1229 user: dan tags: trunk
19:47
Make sure the quota logic is usable as C++. check-in: f4534bd3 user: drh tags: quota-stdio
18:55
Change the multiplexor VFS so that xTruncate is a no-op on database files. check-in: ee1e0122 user: dan tags: trunk
18:21
Fix for the xFileSize method of test_multiplex.c when used on a file opened with the DELETEONCLOSE flag set. check-in: 713071c4 user: dan tags: trunk
16:51
Add magic comments to shell.c to make it easier for scripts to insert additional version information displays for custom builds. check-in: 9b2691aa user: drh tags: trunk
2011-12-11
22:44
In the multiplexor shim, when using 8+3 filenames, begin numbering journal overflow files with 101 instead of 001 to avoid name collisions with the main database file. check-in: 05bf8a0b user: drh tags: trunk
21:51
Update comments describing the flattening optimization in select.c. check-in: dab4c137 user: drh tags: trunk
02:30

02:29
Fix harmless compiler warnings. check-in: 1e6a698a user: drh tags: trunk
2011-12-10
23:18
Minor cleanups of the compound-subquery flattening logic. New test cases added for joins the compound subquery. check-in: 5061d85f user: drh tags: trunk
17:17
Allow UNION ALL compounds to be promoted up to replace a simple wrapper SELECT even if the compounds are joins. check-in: 3d4b4f4f user: drh tags: trunk
15:55
Import the experimental parse-tree explainer, with fixes, from the tree-explain branch. Disabled by default. Use SQLITE_ENABLE_TREE_EXPLAIN to turn it on. check-in: bcbc7152 user: drh tags: trunk

2011-12-09
18:06
Change the VDBE so that all registers are initialized to "Invalid" instead of NULL and report errors on any attempted read of an Invalid register. This will help prevent future bugs similar to [7bbfb7d442]. check-in: 0064bab7 user: drh tags: trunk
17:51
Remove an unnecessary condition. Closed-Leaf check-in: d9ba023c user: drh tags: uninit-vdbe-mem
17:38
Remove an unnecessary initialization of Vdbe.aOnceFlag. check-in: 421714da user: drh tags: uninit-vdbe-mem
17:27
Take out the OP_JumpOnce opcode. Revert compound SELECT to use OP_IfNot, which is the correct behavior. Mark trigger registers as initially invalid. check-in: 6a9fb47d user: drh tags: uninit-vdbe-mem
16:59
Previous check-in broke auto-increment. This check-in appears to fix it. check-in: 28ffd39c user: drh tags: uninit-vdbe-mem
16:21
Make no assumptions about the initial state of VDBE registers. check-in: 521d72bd user: drh tags: uninit-vdbe-mem
13:24

2011-12-07
22:49
Additional detail added to the tree-explain output for SELECT statements. check-in: 7b457ea4 user: drh tags: tree-explain

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
2011-12-03

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. There is no guarantee that any of this will ever make it into trunk. Substantial revision is possible prior to reaching trunk, if it ever does. Closed-Leaf check-in: 8936542b user: drh tags: vfs-stdio
2011-11-29

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
15:27

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
03:17
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

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
2011-11-09

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

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

2011-10-27
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
