2010-06-30
| ||
| 10:36 | Add further test cases. Fix an assert() in pager.c. (check-in: 8e65c0e3 user: dan tags: trunk) | |
| 04:36 | Do not call pager_open_journal() from within PagerBegin() if the connection is in exclusive-access mode. It will be called from within PagerWrite() just as it is for non-exclusive mode anyway. (check-in: cdf2c5c2 user: dan tags: trunk) | |
| 04:29 | Add coverage test cases. Have sqlite3_backup_step() transform SQLITE_IOERR_NOMEM to SQLITE_NOMEM before returning. (check-in: 5e19bc36 user: dan tags: trunk) | |
|
2010-06-29
| ||
| 10:30 | Add tests to pager1.test and pagerfault.test. (check-in: 008513ee user: dan tags: trunk) | |
|
2010-06-28
| ||
| 19:04 | Add extra pager tests. (check-in: 6b7e419d user: dan tags: trunk) | |
| 11:23 | Fix some errors when compiling with SQLITE_OMIT_WAL. (check-in: 3b68cb9c user: dan tags: trunk) | |
| 11:06 | Remove debugging code from test script. (check-in: a85ae332 user: dan tags: trunk) | |
| 10:15 | Currently, if SQLite cannot find a table or index referred to by a query, it reloads the database schema from disk to see if the table or index has been added since the schema was cached in memory. Extend this behaviour to columns (which may have been added using ALTER TABLE) and fix some obscure cases related to tables and indexes (INDEXED BY, DROP TABLE etc.). (check-in: 4932f228 user: dan tags: trunk) | |

| 16:30 | • Ticket [d11f09d3] Cache corruption caused by ROLLBACK with synchronous=NORMAL status still Open with 1 other change (artifact: 16a03c75 user: dan) ... 1 similar event omitted. | |
| 15:42 | When synchronous=NORMAL, use the same journal file format as with synchronous=FULL (i.e. multiple journal headers within the one journal). Fix for [d11f09d36e]. (check-in: 2eaf5ee0 user: dan tags: trunk) | |
| 15:40 | • New ticket [d11f09d3] Cache corruption caused by ROLLBACK with synchronous=NORMAL. (artifact: 4fd136ea user: dan) | |

| 19:09 | Further test cases for pager1.test and pagerfault.test. (check-in: bfd563c4 user: dan tags: trunk) | |
| 16:34 | Reduce the average (but not maximum) size of the allocations made as part of a checkpoint. (check-in: 4a7fd91b user: dan tags: trunk) | |
| 15:16 | Reduce the size of the large allocation (approx 8KB for every 4000 frames in the log) that occurs during checkpoint. Use the 'scratch' memory for this allocation instead of the general purpose allocation. (check-in: 29887487 user: dan tags: trunk) | |
| 11:35 | Modify the merge-sort in wal.c so that it does not use recursion. (check-in: daea6c05 user: dan tags: trunk) | |

| 13:24 | Add a coverage test to pagerfault.test. (check-in: b58db67e user: dan tags: trunk) | |
| 10:50 | Add coverage tests. Remove a NEVER macro from pager.c, as the condition can now be true in wal mode. (check-in: 7aac9ad6 user: dan tags: trunk) | |
|
2010-06-23
| ||
| 19:27 | Add test case for SQLITE_FULL errors to pagerfault.test. Remove a NEVER macro in pager.c that this hits. (check-in: 3e9680c4 user: dan tags: trunk) | |
| 15:55 | Add a version number to the wal-index header. If SQLite encounters a version number in either the wal or wal-index files that it does not understand, the operation is abandoned and SQLITE_CANTOPEN returned. (check-in: 8d0f8a7f user: dan tags: trunk) | |
|
2010-06-22
| ||
| 15:18 | Add codec support to wal mode. (check-in: 393741eb user: dan tags: trunk) | |

|
2010-06-19
| ||
| 19:06 | Fix an assert() failure that could occur if compiling with OMIT_SHARED_CACHE. (check-in: 3e76a9f2 user: dan tags: experimental) | |
| 18:12 | Change the name of IOCAP_SAFE_DELETE to IOCAP_UNDELETABLE_WHEN_OPEN. Have the xDeviceCharacteristics() method of the win32 VFS return this flag. (check-in: 5a5ff4e3 user: dan tags: experimental) | |
| 17:26 | Add tests to pager1.test and pagerfault.test. (check-in: f5df83fd user: dan tags: experimental) | |

| 16:13 | Rearrange some code in OP_JournalMode to avoid incorrect returns from subsequent invocations of "PRAGMA journal_mode" following an IO error. (check-in: ce0a4a9b user: dan tags: experimental) | |
| 11:10 | Change the implementation of the unix implementation of xAccess() so that it returns 0 (does not exist) to an SQLITE_ACCESS_EXISTS query on a file that exists but is zero bytes in size. (check-in: 077b0e5b user: dan tags: experimental) | |
|
2010-06-17
| ||
| 17:05 | Apply [b9b11855e8] (the alternate fix to [fc62af4523]) to the trunk. (check-in: 9a949a3a user: dan tags: trunk) | |
| 16:44 | Merge trunk change [7c3a86b9c7]. (check-in: bd7bc4e0 user: dan tags: experimental) | |
| 16:44 | A different fix to [fc62af4523]. When changing from journal_mode=PERSIST or TRINCATE to some other rollback mode, delete the journal file only if a RESERVED lock can be obtained on the database file first. (check-in: b9b11855 user: dan tags: experimental) | |
| 11:36 | Fix bug in journal2.test. (check-in: c1e04f1d user: dan tags: experimental) | |

| 10:42 | Do not delete the journal file in "PRAGMA journal_mode" commands. This fixes [fc62af4523]. (check-in: 1ec74591 user: dan tags: trunk) | |
| 10:24 | Add test case for [fc62af4523]. (check-in: cccd32c6 user: dan tags: trunk) | |
| 09:52 | • Ticket [fc62af45] Executing "PRAGMA journal_mode" may delete journal file while it is in use. status still Open with 4 other changes (artifact: c98b4147 user: dan) ... 1 similar event omitted. | |

| 19:04 | Experimental change: On systems where it is not possible to unlink a file while one or more processes has it open (i.e. not unix), avoid closing the journal file each time the database is unlocked and reopening it at the start of each transaction. (check-in: bede8c8a user: dan tags: experimental) | |
| 12:30 | Add extra test cases to pager1.test. (check-in: ad320957 user: dan tags: trunk) | |

| 18:00 | Fix a problem introduced into lock2.test by the previous commit. (check-in: c1c9f6fa user: dan tags: trunk) | |
| 17:44 | Add test file pager1.test, containing tests of inter-process locking in non-wal mode. (check-in: 6e43eed9 user: dan tags: trunk) | |
| 14:21 | Run extra iterations in wal3.test to ensure test coverage. (check-in: ea80cbe5 user: dan tags: trunk) | |
| 14:06 | Merge in [2c5e48a485]. Merge in [2c5e48a485]. Merge in [2c5e48a485]. (check-in: 03c0f4fd user: dan tags: trunk) | |
| 13:56 | Changes to the way tcl test scripts work. No changes to production code. (Closed-Leaf check-in: 2c5e48a4 user: dan tags: experimental) | |
| 07:02 | • Edit [2c5e48a4855e2ec4|2c5e48a4]: Timestamp 2010-06-15 13:56:37. (artifact: 52b78394 user: dan) | |
|

| 14:07 | Remove xShmGet/Size/Release from the sqlite3_vfs structure. Change the name of xShmPage to xShmMap. Remove some code that is now unused from os_unix.c and some of the test VFS implementations. (check-in: fc0cabc1 user: dan tags: experimental) | |
| 11:49 | Update some comments in wal.c. No code changes. (check-in: 1ce9c92b user: dan tags: experimental) | |
| 11:18 | Change the interface to internal function walGetHash() to make it easier to follow. (check-in: 5e8e2e97 user: dan tags: experimental) | |

|
2010-06-11
| ||
| 19:04 | Experimental change to the xShmXXX parts of the VFS interface. (check-in: ca68472d user: dan tags: experimental) | |
|
2010-06-10
| ||
| 06:53 | Store the MemPage structure in memory following, instead of preceding, the page data for cached pages. This reduces the likelihood of a corrupt database page image causing SQLite to read past the end of a buffer. (check-in: 0ce42e76 user: dan tags: trunk) | |
|
2010-06-09
| ||
| 19:01 | Fix test script problems causing errors in the "inmemory_journal" permutations. (check-in: ea05b7f9 user: dan tags: trunk) | |
| 16:58 | When restarting (wrapping) a log file, set all unused aReadMark[] slots to READMARK_NOT_USED instead of 0. Setting them to 0 does not cause a problem, but may cause SQLite to obtain and release a few more file locks than would otherwise be necessary. (check-in: 0797b10c user: dan tags: trunk) | |
| 15:47 | Fix for ticket [f973c7ac31]. (check-in: 6eb058dd user: dan tags: trunk) | |
| 11:30 | • Edit [7c102c7b5f90717f|7c102c7b]: Timestamp 2010-06-09 11:02:13. Cancel tag "trunk". (artifact: 4d073dc2 user: dan) | |
| 11:29 | • Edit [7c102c7b5f90717f|7c102c7b]: Timestamp 2010-06-09 11:02:13. Add tag "mistake". (artifact: 4ca4f62e user: dan) | |

| 11:02 | Fix for race condition in WAL locking code. (Closed-Leaf check-in: 7c102c7b user: dan tags: mistake) | |
|
2010-06-08
| ||
| 15:50 | Close database opened by tester.tcl when it is sourced in all.test. Because test scripts are now run in slave interpreters, this connection was not being closed by the first script run as it was previously. (check-in: b072e9f6 user: dan tags: trunk) | |
| 15:16 | Changes to wal3.test to support small default cache size settings. And builds that create autovacuum databases by default. (check-in: ac4cc257 user: dan tags: trunk) | |
|
2010-06-07
| ||
| 19:26 | In os_unix.c, call munmap() to unmap a shared-memory region prior to closing the associated file descriptor. (check-in: 95cc976f user: dan tags: trunk) | |
| 17:47 | Change all.test, quick.test and permutations.test so that they use a separate interpreter for each test file. (check-in: 7c33eb5a user: dan tags: trunk) | |
| 14:28 | Refactor some of the global variables and commands used by tester.tcl. (check-in: c2edf8e1 user: dan tags: trunk) | |
| 06:11 | Add a couple of extra coverage tests for wal.c. (check-in: cfe60254 user: dan tags: trunk) | |
|
2010-06-05
| ||
| 19:18 | Add further test cases for the logic in sqlite3WalBeginReadTransaction(). (check-in: a49713db user: dan tags: trunk) | |
| 18:34 | • Edit [c041c6a9786bc9eb|c041c6a9]: Edit check-in comment. Timestamp 2010-06-05 18:34:26. (artifact: 384ffb6e user: dan) | |
| 18:34 | Clarify the purpose of a test for a race-condition in sqlite3WalBeginReadTransaction(). (check-in: c041c6a9 user: dan tags: trunk) | |
| 18:12 | Remove a condition from sqlite3WalRead() that is unreachable as of the changes to clear entries out of the wal-index hash tables on transaction or savepoint rollback. (check-in: 39420473 user: dan tags: trunk) | |
| 14:42 | Mark a condition in wal.c as ALWAYS(). (check-in: 3fe0cc78 user: dan tags: trunk) | |
| 11:53 | Add extra coverage test cases for wal.c. No changes to production code. (check-in: f9d4ae0e user: dan tags: trunk) | |
|
2010-06-04
| ||
| 18:38 | Clarify an assert in sqlite3WalExclusiveMode(). (check-in: 25585069 user: dan tags: trunk) | |
| 17:16 | Remove an unnecessary branch from wal.c. (check-in: 8e54786c user: dan tags: trunk) | |
| 15:59 | Add an English language error message to corresponding to SQLITE_PROTOCOL. "locking protocol". (check-in: ca327e32 user: dan tags: trunk) | |
| 12:22 | Add test for the code that detects an inconsistent pair of wal-index headers to wal2.test. (check-in: 157feba1 user: dan tags: trunk) | |
| 11:56 | If an attempt to sync the database file as part of a checkpoint fails, do not update the shared "nBackfill" variable. Otherwise, another process could wrap the log and overwrite content before it is synced into the database. (check-in: b813233d user: dan tags: trunk) | |
| 10:37 | Fix a problem where an SQLITE_BUSY in the checkpoint code was being treated as an IO error (abandoning, instead of just limiting, the checkpoint). (check-in: 02c4040c user: dan tags: trunk) | |
|
2010-06-03
| ||
| 19:10 | Fix another problem in test_vfs.c. (check-in: df7d5989 user: dan tags: trunk) | |
| 18:20 | Have test_vfs.c simulate IO errors in xShmLock. (check-in: fcbf7cf1 user: dan tags: trunk) | |
| 16:58 | Add extra tests for removing elements from wal-index hash tables as part of a rollback. (check-in: af3e598a user: dan tags: trunk) | |
| 12:35 | Delay opening the sub-journal until SQLite actually needs to write data to it. (check-in: c43deb33 user: dan tags: trunk) | |
| 09:25 | Enhancements to test_vfs.c and walfault.test. (check-in: ac0de2f3 user: dan tags: trunk) | |
| 09:18 | • Edit [eb80ddc665132c60|eb80ddc6]: Edit check-in comment. Timestamp 2010-06-03 09:17:38. (artifact: c11136be user: dan) | |
| 09:17 | If an error (OOM or SQLITE_FULL error) occurs while executing an SQL statement and a statement-transaction is automatically rolled back as a result, if a second error occurs during the statement rollback do a full transaction rollback instead. Otherwise the client can be left with an inconsistent cache. This can affect both WAL and rollback modes. (check-in: eb80ddc6 user: dan tags: trunk) | |
| 09:01 | If a malloc fails while allocating a savepoint object at the pager level, do not try to roll that savepoint back later on. (check-in: 91cb08ff user: dan tags: trunk) | |
|
2010-06-02
| ||
| 18:59 | Fix a problem with rolling back to a savepoint opened before the writer decided to wrap the log file. (check-in: 6b4aed6a user: dan tags: trunk) | |
| 17:15 | If an error occurs while writing frames to the log to commit a transaction, do not mark the pages as clean in the cache. Otherwise, the subsequent rollback does not roll them back (leaving the client to continue with a cache that makes it appear that the transaction was committed - inconsistent with the database on disk). (check-in: cb571c1b user: dan tags: trunk) | |
| 05:53 | Add some 'const' markers to static data that is really constant. (check-in: e7073e23 user: dan tags: trunk) | |
|
2010-06-01
| ||
| 19:15 | Changes to the way faults are injected into xShmXXX VFS calls. (check-in: 716d99f3 user: dan tags: trunk) | |
| 17:46 | Change the OOM and IO error test cases in walfault.test so that each test case runs both types of error simulation. (check-in: b627e153 user: dan tags: trunk) | |
| 15:44 | Delay the decision to restart the log file until data is actually ready to be written to the log file (instead of at the start of a write transaction). (check-in: b1abfaaf user: dan tags: trunk) | |
| 14:30 | Merge with [15abbc3416]. (Closed-Leaf check-in: f4b9003a user: dan tags: wal-incr-ckpt) | |
| 14:12 | If an attempt to get a read-lock on the WAL fails with SQLITE_BUSY_RECOVER, call the busy-handler at the btree level. (check-in: ce644965 user: dan tags: wal-incr-ckpt) | |
| 11:08 | Do not hold the shared-memory mutex in os_unix.c if returning NULL. (check-in: 9622dd46 user: dan tags: wal-incr-ckpt) | |
| 10:44 | If the checkpoint fails to obtain an exclusive lock on one of the read-lock bytes, do not consider this an error. (check-in: 9e95e357 user: dan tags: wal-incr-ckpt) | |
| 07:51 | Fixes to the test cases in wal2.test. (check-in: cd5fbcbc user: dan tags: wal-incr-ckpt) | |
