| 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: a0be6ea464 user: drh tags: statvfs) | |
| 16:25 | Fix a bad #endif with the previous check-in on this branch. (check-in: 915713ffe4 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: e0d44450b9 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: 44ca4d1233 user: drh tags: trunk) | |
| 08:10 | Add tests to walcrash3.test. (check-in: d768804280 user: dan tags: trunk) | |
| 01:31 | Make sure the Salt-1 value in the WAL file is sequentially numbered at each checkpoint, as it says it should be in the documentation. (check-in: 7b63b11b93 user: drh tags: trunk) | |

| 21:26 | Enhance the WAL header sync so that it honors the various synchronous pragmas, settings, and device characteristics. (Closed-Leaf check-in: 9799241f7d 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: 91d0437c07 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: 49d21ce50f 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: 09ccc4a1be user: drh tags: trunk) | |
| 15:11 | Improved logging of master-journal name conflicts. (check-in: b1005ef46c user: drh tags: trunk) | |
| 13:42 | Merge the nx-devkit changes into trunk. (check-in: cf3bccc2e9 user: drh tags: trunk) | |
| 13:24 | Experimental fix for [a1fa75cbdd]. (Closed-Leaf check-in: 6492af76ea user: dan tags: experimental) | |

| 17:44 | Add stdio support to the quota VFS. (check-in: 322bd15f97 user: drh tags: trunk) | |

| 18:33 | Merge the nx-devkit changes into trunk. This includes the new SQLITE_FCNTL_VFSNAME file-control. (check-in: da118e02c0 user: drh tags: trunk) | |
| 00:37 | Treat a zero return value from the Win32 APIs MultiByteToWideChar and WideCharToMultiByte as an error condition. (check-in: c65e5a36f1 user: mistachkin tags: trunk) | |

| 15:37 | Merge the nx-devkit changes into trunk. (check-in: 03a70c3dae 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: 199f52bced 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: 255d21499b user: dan tags: experimental) | |
|

| 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: 169e12295c user: dan tags: trunk) | |
| 18:55 | Change the multiplexor VFS so that xTruncate is a no-op on database files. (check-in: ee1e012256 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: 713071c493 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: 9b2691aa91 user: drh tags: trunk) | |
|

| 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: 05bf8a0b17 user: drh tags: trunk) | |
| 21:51 | Update comments describing the flattening optimization in select.c. (check-in: dab4c137a8 user: drh tags: trunk) | |
| 02:30 | Fix STAT3 so that it works with the new uninitialized register logic of the VDBE. Ticket [7bbfb7d4422ff] (check-in: d11a57985c user: drh tags: trunk) | |
| 02:29 | Fix harmless compiler warnings. (check-in: 1e6a698aab user: drh tags: trunk) | |
|

| 23:18 | Minor cleanups of the compound-subquery flattening logic. New test cases added for joins the compound subquery. (check-in: 5061d85ff9 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: 3d4b4f4fb7 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: bcbc7152d4 user: drh tags: trunk) | |
| 14:44 | Merge the latest trunk changes into tree-explain branch. (Closed-Leaf check-in: 1a360da0f8 user: drh tags: tree-explain) | |
| 13:49 | Always use _msize() to get memory allocation sizes on windows, without having to do anything special in the makefile. (check-in: 256e27bd11 user: drh tags: trunk) | |
|

| 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: 0064bab771 user: drh tags: trunk) | |
| 17:51 | Remove an unnecessary condition. (Closed-Leaf check-in: d9ba023c60 user: drh tags: uninit-vdbe-mem) | |
| 17:38 | Remove an unnecessary initialization of Vdbe.aOnceFlag. (check-in: 421714dad3 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: 6a9fb47d50 user: drh tags: uninit-vdbe-mem) | |
| 16:59 | Previous check-in broke auto-increment. This check-in appears to fix it. (check-in: 28ffd39c71 user: drh tags: uninit-vdbe-mem) | |
| 16:21 | Make no assumptions about the initial state of VDBE registers. (check-in: 521d72bdf6 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: 557c69055a user: dan tags: trunk) | |
| 05:52 | The Windows OS flavor #ifdefs must be performed after the 'windows.h' file has been included. (check-in: 3702a31e56 user: mistachkin tags: trunk) | |

| 21:08 | Merge the latest trunk changes into the apple-osx branch. (check-in: 59e0d4f3d9 user: drh tags: apple-osx) | |
| 20:41 | Hand merge the zone allocator for MacOS from the apple-osx branch. (check-in: 0d955c20c0 user: drh tags: trunk) | |
| 19:50 | In persistent WAL mode, truncate the WAL file to the size specified by the journal_size_limit pragma when disconnecting from the WAL. (check-in: 9687b305c2 user: drh tags: trunk) | |
| 03:51 | Follow the previously established pattern for detecting preprocessor defines for specific flavors of Windows (for NT in this case). (check-in: a0d92193dd user: mistachkin tags: trunk) | |
|

| 22:49 | Additional detail added to the tree-explain output for SELECT statements. (check-in: 7b457ea455 user: drh tags: tree-explain) | |
| 15:33 | More compact notation for the parse-tree view. (check-in: 0eb3f8b1e3 user: drh tags: tree-explain) | |
| 01:55 | Cherrypick the [7e5b56b1c6] fix for the sqlite3SelectDup() routine into trunk. (check-in: 7fc535090c user: drh tags: trunk) | |
| 01:47 | Bug fix in sqlite3SelectDup(). Make sure the pNext pointer is valid. (check-in: 7e5b56b1c6 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: 0aa7d3d234 user: drh tags: tree-explain) | |
|
2011-12-06
| ||
| 19:44 | Begin adding the data-structure explaining subsystem. All is contained within (check-in: 79ae51c5b1 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: 162421dadf user: dan tags: trunk) | |
