2011-12-21
18:04
Fix other problems where 32-bit integer overflow may cause a problem. Two that require an improbably large sub-journal and two in test harness code. Ticket [ac0ff496b7e2] (check-in: c723e3e1 user: dan tags: trunk)
17:00
Avoid 32-bit overflow when calculating the byte offset of an overflow page in SQLITE_DIRECT_OVERFLOW_READ code. Fix for [ac0ff496b7]. (check-in: c5256b59 user: dan tags: trunk)
14:42
Add the ability to enable or disable SQLITE_IOCAP_ZERO_DAMAGE using a URI parameter for both unix and windows. Add a file-control to query or disable the ZERO_DAMAGE setting. Add the -uri option to the "sqlite3" TCL command in tclsqlite3.c. Allow the sqlite3_uri_parameter() interface to accept a NULL pointer for its first parameter. (check-in: c83627b7 user: drh tags: statvfs)
2011-12-20
22:18
Remove the code that tries to detect OOO header writes on a WAL recovery. The code is made obsolete by syncing the WAL header. (check-in: 7ac713a1 user: drh tags: statvfs)
20:13
Refactor the sqlite3WalFrames() routine for clarity of presentation. Do the padded transaction sync as the write pointer crosses the final sector boundary instead of at the end, for efficiency. Always sync the WAL header immediately after it is written. (check-in: 92c73b42 user: drh tags: statvfs)
13:13
Assert that the isCommit parameter to sqlite3WalFrames() is zero if and only if the nTruncate parameter is zero. (check-in: 979daf92 user: drh tags: trunk)
2011-12-19
15:46

2011-12-17
20:02
For improved clarity of presentation, refactor some of the code associated with ZERO_DAMAGE and sector-size. (check-in: 1dde96c9 user: drh tags: statvfs)
19:49
Add SQLITE_IOCAP_ZERO_DAMAGE and enable it for both unix and windows. Use this device characteristic to reduce the required work in journaling. A side effect is that this changes the default page exists back to 1024 even with the use of statvfs(). (check-in: a0be6ea4 user: drh tags: statvfs)
16:25
Fix a bad #endif with the previous check-in on this branch. (check-in: 915713ff user: drh tags: statvfs)
16:09
Add support for statvfs() in os_unix.c, for determining the sector size. This causes many TCL test failures under Linux. (check-in: e0d44450 user: drh tags: statvfs)
13:45
Merge in changes that cause the first sector of the WAL file to be synced when the WAL restarts. This is a fix for the power-loss corruption problem described in ticket [ff5be73dee086] (check-in: 44ca4d12 user: drh tags: trunk)
08:10
Add tests to walcrash3.test. (check-in: d7688042 user: dan tags: trunk)
01:31

2011-12-16
21:26
Enhance the WAL header sync so that it honors the various synchronous pragmas, settings, and device characteristics. (Closed-Leaf check-in: 9799241f user: drh tags: wal-header-sync)
19:34
Proposed changes that ensure that the WAL header is written prior to the first commit mark. (check-in: 91d0437c user: drh tags: wal-header-sync)
17:01
Add code for a test that was failing before the persistent-wal related changes of [09ccc4a1be]. (check-in: 49d21ce5 user: dan tags: trunk)
15:38
Merge the fix for [a1fa75cbdd02] from the experimental branch. Also fix the persistent-wal mode feature of truncating the WAL on close so that it always truncates the WAL to zero bytes. (check-in: 09ccc4a1 user: drh tags: trunk)
15:11
Improved logging of master-journal name conflicts. (check-in: b1005ef4 user: drh tags: trunk)
13:42
Merge the nx-devkit changes into trunk. (check-in: cf3bccc2 user: drh tags: trunk)

2011-12-13
15:37
Merge the nx-devkit changes into trunk. (check-in: 03a70c3d user: drh tags: trunk)
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)
2011-12-12
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)
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)

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)

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)

Make no assumptions about the initial state of VDBE registers. (check-in: 521d72bd user: drh tags: uninit-vdbe-mem)
13:24
Modify the OP_Once opcode so that it works correctly in trigger sub-programs. This is a candidate fix for [7bbfb7d442]. (check-in: 557c6905 user: dan tags: trunk)
05:52
The Windows OS flavor #ifdefs must be performed after the 'windows.h' file has been included. (check-in: 3702a31e user: mistachkin tags: trunk)
2011-12-08
21:08
Merge the latest trunk changes into the apple-osx branch. (check-in: 59e0d4f3 user: drh tags: apple-osx)
20:41
Hand merge the zone allocator for MacOS from the apple-osx branch. (check-in: 0d955c20 user: drh tags: trunk)

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.
