2010-05-18
| ||
| 12:37 | Keep additional state information in the pager in an effort to reduce the number of SQLITE_FCNTL_SIZE_HINTs. (Note: This change was found to make no performance difference and so has been moved onto a side branch. Use the parent check-in instead of this one.) Closed-Leaf check-in: 97d88a86 user: drh tags: branch-3.6.1-exp | |
|
2010-05-17
| ||
| 20:16 | Remove an unreachable test from wal.c. check-in: 7162c456 user: drh tags: trunk | |
| 15:52 | An improvement to the SQLITE_FCNTL_SIZE_HINT change that invokes the hint less often and only when really needed. check-in: a1d20ceb user: drh tags: branch-3.6.1 | |
| 15:33 | Invoke the SQLITE_FCNTL_SIZE_HINT opcode on the sqlite3_file_control() interface for database files before extending the size of the file. The VFS can use this hint to preallocate space. check-in: 9a083711 user: drh tags: branch-3.6.1 | |
|
2010-05-15
| ||
| 10:24 | Add a note to the documentation of sqlite3_wal_hook() to say not to return SQLITE_ROW or SQLITE_DONE. Or any other value that is not a valid SQLite error code. check-in: 2f0b6cbf user: dan tags: trunk | |
| 01:09 | Silently ignore errors trying to set the default journal_mode while doing an ATTACH. check-in: b9af4ad2 user: drh tags: trunk | |
|
2010-05-14
| ||
| 20:15 | Fix a typo that (by bad luck) was not a syntax error but which caused some important lines of code to be skipped when SQLITE_DEBUG was not used. check-in: 9ef99d97 user: drh tags: trunk | |
| 19:24 | Make sure the value of an INTEGER PRIMARY KEY column supplied to triggers and especially to FK constraints really contains the ROWID and not the NULL that is stored in the column itself. Ticket [dd08e5a988d00dec]. check-in: 636f8609 user: drh tags: trunk | |
| 16:34 | Pull in all the latest changes from the trunk. Update the win32 SHM methods to work with the new interface design. Closed-Leaf check-in: 4b69f2cd user: drh tags: wal-win32 | |
| 14:52 | Simplifications to the SHM implementation in os_unix.c, taking advantage of the removal of the LinuxThreads mess. check-in: d1debe5d user: drh tags: trunk | |
| 12:43 | Simplify os_unix.c by removing support for LinuxThreads. Linux systems must either use NPTL or else not share database connections across threads. check-in: e294b696 user: drh tags: trunk | |
| 11:30 | Change the OSTRACEn() macro to OSTRACE(()). Also rename some internal fields and variables in os_unix.c to be more meaningful and searchable. check-in: 5fe529f2 user: drh tags: trunk | |
| 10:43 | Fix test_osinst.c so that it does not depend on gettimeofday() unless SQLITE_OS_UNIX is defined and NO_GETTOD is not defined. check-in: 2a4014b7 user: dan tags: trunk | |
| 08:39 | Add xShmXXX methods to test_osinst.c. check-in: b8a9b37a user: dan tags: trunk | |
|
2010-05-13

| 20:19 | Make debugging elements of the sqlite3_mutex object volatile and make them only appear when compiling with SQLITE_DEBUG. Ticket [51914f6acd2cb462]. check-in: e823c60c user: drh tags: trunk | |
| 15:44 | Allow sqlite3WalCheckpoint() to be called even if the WAL is in the SQLITE_SHM_READ state, as sometimes happens after an error. check-in: 175b296f user: drh tags: trunk | |
| 09:40 | Remerge mistaken test_osinst.c changes. check-in: e8c10d3c user: dan tags: trunk | |

| 06:19 | Modify the VFS in test_vfs.c to match the refactoring of the xShmXXX methods. check-in: 25e72f81 user: dan tags: wal-refactor | |
|
2010-05-12
| ||
| 19:02 | (Moved to the mistake branch due to compile errors in test_osinst.c.) Change the vfs instrumentation code in test_osinst.c to make it easier to deploy. Add a vtab implementation for reading the binary log file format. check-in: ee13c884 user: dan tags: mistake | |
| 18:30 | Fix for the test_devsym.c test module for the VFS-SHM refactoring. check-in: 49d62933 user: drh tags: wal-refactor | |
| 18:10 | A couple simple fixes to get wal.test mostly working. check-in: c7445812 user: drh tags: wal-refactor | |
| 18:01 | Refactoring the VFS-SHM methods used by WAL. This version compiles and runs non-WAL test cases but crashes and burns on wal.test. check-in: 2b00152c user: drh tags: wal-refactor | |
| 17:14 | Updates to WAL support in os_win.c: pulled in latest changes from src/os_unix.c; updated tracing; misc. improvements. check-in: 76504726 user: shaneh tags: wal-win32 | |
| 13:50 | Remove the OP_Variable optimization of check-in [48b77b04935d894] since it can lead to malfunctions as described in ticket [26ff0c82d1e90]. check-in: 7838163d user: drh tags: trunk | |
| 06:54 | Remove a branch made redundant by the earlier exclusive-mode changes. check-in: c501b2ed user: dan tags: trunk | |
|
2010-05-11
| ||
| 16:29 | Have os_unix.c use the suffix "-wal-index" for wal-index files instead of "-wal-inde". check-in: 885e854e user: dan tags: trunk | |
| 14:00 | When an attempt to change journal_mode fails due to locks, be sure to leave internal structures in a consistent state. check-in: cf3d1e0b user: drh tags: trunk | |
| 12:19 | Changes so that WAL and exclusive-locking mode work together. check-in: 71e7b1cf user: dan tags: trunk | |
| 02:49 | Initial port of WAL VFS support from os_unix.c to os_win.c. check-in: 111ad59f user: shaneh tags: wal-win32 | |
| 02:46 | Updates to WAL TCL test scripts to support running on Windows. check-in: 6a563080 user: shaneh tags: trunk | |
|
2010-05-10
| ||
| 19:51 | Fix an off-by-one error while constructing the name of the mmap file for the wal-index under os_unix.c. check-in: 6e3735f7 user: drh tags: trunk | |

| 14:46 | Modify the format of the wal-index to use a hash table to index log file segments. check-in: 40b0a635 user: dan tags: trunk | |
| 14:10 | If an ATTACH command fails due to OP_JournalMode but still attaches the database, make sure VACUUM still detaches it when done. check-in: 6ecdc7ba user: drh tags: trunk | |
| 11:20 | Enhance the OP_JournalMode opcode with an ignore-errors option and use that option the ATTACH command. check-in: 0bdea4cf user: drh tags: trunk | |
|
2010-05-07
| ||
| 20:34 | When running a checkpoint while in locking_mode=EXCLUSIVE, be sure to move the wal-index lock to UNLOCK from READ prior to promoting to CHECKPOINT. check-in: be114bdf user: drh tags: trunk | |
| 20:02 | Change the xShmOpen() method of the VFS to take the database file name as its argument, not the WAL file name. Also fix some unrelated compiler warnings. check-in: a65c2939 user: drh tags: trunk | |
| 18:23 | Additional tweaks to API documentation. No functional code changes. check-in: e1230782 user: drh tags: trunk | |
| 13:57 | Updates to documentation on the C interfaces supporting WAL. No functional changes to code. check-in: 681ba20c user: drh tags: trunk | |
| 13:52 | Fix a recently introduced problem in wal.test. check-in: 79b52d0f user: dan tags: trunk | |
| 12:49 | Change wal.test and walhook.test so that they work with DEFAULT_AUTOVACUUM=1 builds. check-in: 4cde9290 user: dan tags: trunk | |
| 09:43 | Test another IO error case in wal.c. check-in: 8b3b5ab8 user: dan tags: trunk | |
| 06:59 | Fix a problem with checkpointing large log files created by an external process. check-in: 8f94bde5 user: dan tags: trunk | |
| 05:46 | Since walIndexTryHdr() can no longer encounter any error conditions, change tehe function signature so that it does not return an error code. This removes unreachable branches from other code. check-in: 061a282c user: dan tags: trunk | |
| 00:28 | Another attempt to fix permutations.test so that it excludes WAL tests from the journaltest permutation. check-in: 58c40442 user: drh tags: trunk | |
|
2010-05-06
| ||
| 22:21 | Remove savepoint6.test from the set of tests run by journaltest since savepoint6.test uses journal_mode=WAL. check-in: 811b45a9 user: drh tags: trunk | |
| 21:37 | The PRAGMA journal_mode=WAL; command now makes WAL the default journal mode for new databases added with ATTACH, so the behavior is consistent with the other journal modes. check-in: c3520460 user: drh tags: trunk | |
| 20:19 | Make sure to do a clean shutdown of the library upon existing the shell in order to remove WAL files. check-in: c1762dda user: drh tags: trunk | |
| 19:55 | Exclude all WAL tests from the journaltest permutation. check-in: 46c97d7e user: drh tags: trunk | |
| 19:20 | Changes to support SQLITE_OMIT_WAL. check-in: 32a8501d user: shaneh tags: trunk | |
| 19:04 | Updates to the VFS SHM locking documentation. check-in: 9927ce42 user: drh tags: trunk | |
| 18:48 | Instead of transitioning to RECOVER state from CHECKPOINT when a recovery is required, perform the recovery while holding the CHECKPOINT lock. check-in: bb0b6021 user: dan tags: trunk | |
| 18:27 | If recovery is run before a checkpoint, change back to a CHECKPOINT lock before performing the actual checkpoint. check-in: dc98ee16 user: dan tags: trunk | |
| 18:04 | Only pass -1 as the size parameter to xShmGet when the caller does not care what size mapping is returned. Only call xShmSize when the underlying allocation (not the mapping) should be resized. check-in: 637f51dd user: dan tags: trunk | |
| 17:28 | Fix a bug whereby an old snapshot could be checkpointed (and subsequent transactions discarded) if the last connection to disconnect from a WAL database happended to be holding an out-of-date wal-index header. check-in: d0c0034b user: dan tags: trunk | |
| 16:06 | After throwing an error to say that one cannot change into WAL mode within a tranactions, do not then go and change into WAL mode. check-in: 56a17dae user: drh tags: trunk | |
| 15:56 | Further coverage tests. check-in: 98a9713e user: dan tags: trunk | |
| 15:36 | Update configure scripts for WAL support. check-in: 2edc5129 user: shaneh tags: trunk | |
| 14:42 | Add tests to cover a couple of branches in wal.c. check-in: 429f437f user: dan tags: trunk | |
| 13:36 | Unset a tcl variable before reusing it in wal.test. check-in: e83efb23 user: dan tags: trunk | |
| 12:15 | Add tests for some lock-contention cases. check-in: f0fcb9c9 user: dan tags: trunk | |
| 11:56 | Remove the noop-mutex implementations of mutex_held() and mutex_notheld() since they are both unreachable. check-in: 6767b62a user: drh tags: trunk | |
| 11:55 | Add two text files containing pager design notes to the doc/ subfolder. check-in: ed817fc8 user: drh tags: trunk | |
| 11:32 | Add test cases to test the libraries handling of corrupt wal-index headers. check-in: 9465b267 user: dan tags: trunk | |
| 07:43 | Add tests for handling errors returned by xShm VFS methods. check-in: fbbcacb1 user: dan tags: trunk | |
|
2010-05-05
| ||
| 20:00 | Change the behavior of the sqlite3_wal_hook() callback. It should now return SQLITE_OK or an error code and the error code is propagated back up the stack. If a checkpoint is desired, the callback should invoke sqlite3_wal_callback() itself. check-in: 1b14195e user: drh tags: trunk | |
| 19:09 | Further simplifications to the SHM locking logic. Remove the SQLITE_SHM_QUERY option. Unify the WRITE to READ and RECOVER to READ transitions. check-in: e9bfa6e4 user: drh tags: trunk | |
| 19:04 | Test the handling of errors returned by the xShmXXX() APIs. check-in: 72663123 user: dan tags: trunk | |
| 18:46 | Do not compare page sizes on source and destination of backup until transactions are started and the page sizes are locked. This is a fix to check-in [7bd44794c4]. check-in: ec715778 user: drh tags: trunk | |
| 18:20 | Simplifications to the SHM locking implementation in os_unix.c. check-in: 9de05bfb user: drh tags: trunk | |
| 16:23 | Prohibit backup if the destination is using WAL and has a different page size from the source. check-in: 7bd44794 user: drh tags: trunk | |
| 15:33 | When closing a WAL database, if the exclusive lock on the database file is obtained and the database successfully checkpointed, delete the wal-index file from the file system. check-in: 2ac5d96c user: dan tags: trunk | |
| 04:11 | Make sure the page size of the main database is fixed following a failed VACUUM attempt. Otherwise, two consecutive failed VACUUM attempts with attempted page_size changes on encrypted or WAL databases could result in database corruption. check-in: 208e7d5d user: drh tags: trunk | |
| 03:39 | Do not attempt to modify the page_size when running VACUUM on a WAL database. check-in: 58a1a59b user: drh tags: trunk | |
| 00:22 | Get the previous mutex fix working with SQLITE_DEBUG and with the amalgamation. check-in: df19928f user: drh tags: trunk | |
| 00:05 | When the in single-threaded mode, the sqlite3_mutex_alloc() interface still returns a non-NULL value. The mutex doesn't do anything, but it tests non-NULL. This way, extensions (or VFSes) that use sqlite3_mutex_alloc() can tell the difference between an OOM error and mutexes being disabled. check-in: 451fd175 user: drh tags: trunk | |

| 18:50 | When sqlite3PagerPagecount() is called without any locks, always return the physical file size, not the logical file size. check-in: 4016b422 user: drh tags: trunk | |
| 17:38 | Be sure to release all wal-index locks before closing the wal-index. check-in: b15b67fa user: drh tags: trunk | |
| 17:20 | Relax an over-zealous assert() in sqlite3WalUndo(). check-in: 8f9d22d5 user: drh tags: trunk | |
| 16:33 | Take care not to invoke the xShmClose method of the VFS with a NULL shared memory object. check-in: 1465d384 user: drh tags: trunk | |
| 15:20 | Add a test case to verify that log files containing pages that are not a power-of-two bytes in size are handled correctly. check-in: c2bf693f user: dan tags: trunk | |
| 14:47 | Fix problems with recovering wal files that use a page-size other than the default. check-in: 1a391f3c user: dan tags: trunk | |
| 11:06 | Fix a typo in walfault.test. check-in: 232dbe8e user: dan tags: trunk | |
| 10:36 | Test that the correct number of padding frames are appended to the log file after committing a transaction in synchronous=FULL mode. check-in: a60104aa user: dan tags: trunk | |

| ||
| 19:20 | Unset some global TCL variables prior to use in test where prior tests can have those same variables set to an array value. check-in: 49bef00e user: drh tags: trunk | |
| 19:17 | Fix a bug in the computation of the current time for the alternative CURRENT_TIMESTAMP functions used when SQLITE_OMIT_DATETIME is defined. check-in: e7ded46b user: drh tags: trunk | |
| 18:51 | Documentation stubs for sqlite3_wal_autocheckpoint and sqlite3_wal_checkpoint. check-in: 31376242 user: drh tags: trunk | |
| 18:22 | Fix a bug in the xCurrentTime() method of the os_unix.c VFS. check-in: 551df11a user: drh tags: trunk | |
| 18:01 | Add a test to simulate an OOM during log recovery to walfault.test. check-in: 7ed85e87 user: dan tags: trunk | |
| 17:24 | Clear global variable "seconds" before use in walthread.test. check-in: a35551a5 user: drh tags: trunk | |
| 17:18 | Fix a couple of errors in WAL code that can occur in an OOM situation. check-in: 9d3f3736 user: dan tags: trunk | |
| 16:36 | Update the crash-test VFS in test6.c to pass-through the shared-memory methods to the real underlying VFS. This fixes the walcrash.test script. check-in: ea09ff37 user: drh tags: trunk | |
| 16:30 | Change the VFS definition so that all methods take a VFS object pointer as their first parameter. check-in: 43b5b07f user: drh tags: trunk | |
| 15:58 | Have sqlite3_wal_checkpoint() handle a zero-length string in the same way as a NULL pointer. Fix "PRAGMA wal_checkpoint" so that it checkpoints all attached databases. check-in: 7fecd21f user: dan tags: trunk | |
