| 10:55 | Before calling Tcl_ExitThread() in a multi-threaded test, call Tcl_DoOneEvent() as many times as necessary to handle any queued events. (check-in: b3399b4078 user: dan tags: trunk) | |
| 09:29 | Reorder variable declarations in the previous check-in to avoid putting code before declarations when not testing. (check-in: d1fe8ab4a1 user: drh tags: trunk) | |
| 07:36 | Ensure the correct error code is returned if an attempt to parse a database schema made by an ATTACH statement fails. (check-in: c272196115 user: dan tags: trunk) | |
|

| 21:00 | Modify the VFS xAccess() method on winNT so that it returns false for an exists test of a zero-length file. This makes the windows VFS work the same as the unix VFS. (check-in: ec35f25403 user: drh tags: trunk) | |
| 19:13 | Simplify the previous commit by removing the pagerCheckForOrDeleteWAL() wrapper. (check-in: a1324d125e user: dan tags: trunk) | |
| 19:03 | Allocate a buffer containing the full path-name to the associated WAL file when a pager is created. This saves having to construct a new buffer each time a new read-transaction is opened and SQLite checks for the existance of a WAL file. (check-in: 3053a4ad15 user: dan tags: trunk) | |
| 17:43 | When rolling back page 1 from a journal, restore the "nReserve" setting in case it has been corrupted by a prior crash. (check-in: c0d124da88 user: drh tags: trunk) | |
| 14:54 | Do not report an error if the open-file-count is not as it should be after running a multi-threaded test. The counter instrumentation is not thread-safe. (check-in: ea80b21c88 user: dan tags: trunk) | |
| 12:54 | Call Tcl_ExitThread() from within threads created using Tcl_CreateThread(). Not doing so causes notifier related errors on OSX. (check-in: 684eae6623 user: dan tags: trunk) | |
| 05:54 | Add any files specified as part of the QUICKTEST_INCLUDE environment variable to the set of test files run as part of "make test". Release testing uses this trick. (check-in: a40a6e7df1 user: dan tags: trunk) | |
| 05:31 | Fix typos in permutations.test. (check-in: b6600ecb4e user: dan tags: trunk) | |
|
2010-07-03

| 19:08 | Do not run the memsubsys1.test script under the memsubsys1 permutation. (check-in: 3a1a8c77a5 user: dan tags: trunk) | |
| 17:13 | Remove the unused xRename() method from the sqlite3_vfs object. Add better documentation on the xCurrentTimeInt64() method. (check-in: 51ec0e5432 user: drh tags: trunk) | |
| 16:37 | Further changes to test scripts so that the "inmemory_journal" permutation works. (check-in: 50f2f7dfd6 user: dan tags: trunk) | |
| 13:59 | Fix a bug in the permutations.test script. (check-in: 3b20ad03be user: dan tags: trunk) | |

| 13:45 | Fix an assert in pager.c. And various test cases that fail with the in-memory journal permutation. (Closed-Leaf check-in: 78fc35ff4b user: dan tags: mistake) | |
| 12:31 | Cherry-pick the correct changes out of the recent "mistake" branch while omitting the bugs. (check-in: 48bf309391 user: drh tags: trunk) | |
| 12:26 | Remove dead code from the pager. (check-in: 7cbe175a69 user: drh tags: mistake) | |
| 12:00 | Print the SQLite source_id() string when running speed tests. (check-in: 6d7640edcd user: drh tags: mistake) | |
| 10:00 | Fix an assert() in pager.c added by the previous commit. And various problems with test scripts in autovacuum and in-memory journal mode. (check-in: 62a1010177 user: dan tags: mistake) | |
| 08:01 | Do not attempt to open a WAL file for an in-memory or temporary database. Even if the database header suggests that it is a WAL database. (check-in: 0fd8092436 user: dan tags: mistake) | |
| 05:56 | Change code in OP_Rewind to avoid a valgrind warning following an error in the btree layer. This change does not fix any bug, just a warning. (check-in: 4f62dbcfc9 user: dan tags: mistake) | |
| 01:44 | Fix a buffer overrun in the where.c. Problem detected by valgrind. (check-in: 15bb623306 user: drh tags: mistake) | |
|
2010-07-02
| ||
| 19:49 | Changes to os_win.c to have it return same error code as os_unix.c. (check-in: 33b6f069d8 user: shaneh tags: mistake) | |
| 19:36 | Omit the OP_JournalMode opcode from the VDBE when SQLITE_OMIT_PRAGMA is defined. (check-in: 565ff65c61 user: drh tags: mistake) | |
| 19:04 | Fix a bug in test_vfs.c causing an assert to fail. Changes to test code only. (check-in: 336ce7d297 user: dan tags: mistake) | |
| 18:58 | Do not run the tests in notify3.test unless the unlock-notify API is available. (check-in: 0d7fd6fe9d user: dan tags: mistake) | |
| 18:44 | Take out the incomplete initializer on the constant "dummy" in sqlite3VdbeGetOp(). Add a comment that the MSVC warning there should be ignored. (check-in: 452ccaa908 user: drh tags: mistake) | |
| 18:15 | Fix a couple more compiler warnings under MSVC. (check-in: 26bc27e3f4 user: shaneh tags: mistake) | |

| 17:07 | Remove a couple of C++ style comments from pager.c. (check-in: 4f12e8ebde user: drh tags: mistake) | |
| 17:05 | Fix some warnings when compiling under MSVC. (check-in: 7083387739 user: shaneh tags: mistake) | |
| 16:36 | Add initializers for the xShmXXX() members to an sqlite3_io_methods structure in journal.c. This doesn't fix any real problem, just prevents a compiler warning. (check-in: dafb3577a2 user: dan tags: trunk) | |
| 15:35 | Remove an unused call to sqlite3PageBegin() from pager_write(). Replace it with an assert(). (check-in: 01c1278263 user: drh tags: trunk) | |
| 13:49 | Run tkt-9d68c883.test along with the other pager.c coverage tests. Add a test case to pager1.test. (check-in: c6714b0dbd user: dan tags: trunk) | |
| 11:27 | Additional test cases to cover branches in pager.c. (check-in: eddfb2b406 user: dan tags: trunk) | |
| 01:18 | Add a NEVER to sqlite3PagerCommitPhaseTwo() because it is now no longer possible to invoke that function without holding a RESERVED lock. (check-in: 6ae7617298 user: drh tags: trunk) | |
|
2010-07-01
| ||
| 19:45 | If you delete a database file but not its *-wal file, then open the database (thus creating a new empty database file) the *-wal file is automatically deleted. (check-in: 95c69dfbdd user: drh tags: trunk) | |
| 19:01 | Add tests to pager1.test and pagerfault.test. (check-in: c6e7595092 user: dan tags: trunk) | |
| 15:09 | Add pager test cases. Change a condition in pager.c to NEVER(). (check-in: a8f6341d3b user: dan tags: trunk) | |
|
2010-06-30
| ||
| 10:36 | Add further test cases. Fix an assert() in pager.c. (check-in: 8e65c0e3da 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: cdf2c5c2dd 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: 5e19bc360e user: dan tags: trunk) | |

| 11:23 | Fix some errors when compiling with SQLITE_OMIT_WAL. (check-in: 3b68cb9c65 user: dan tags: trunk) | |
| 11:06 | Remove debugging code from test script. (check-in: a85ae33246 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: 4932f22848 user: dan tags: trunk) | |
|
2010-06-26
| ||

| 17:15 | Fix a case where the doNotSyncSpill flag may remain permanently set following an IO error. (check-in: 56c7d111bf user: dan tags: trunk) | |
| 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: 2eaf5ee0d9 user: dan tags: trunk) | |
|
2010-06-25
| ||
| 19:09 | Further test cases for pager1.test and pagerfault.test. (check-in: bfd563c471 user: dan tags: trunk) | |
| 16:34 | Reduce the average (but not maximum) size of the allocations made as part of a checkpoint. (check-in: 4a7fd91b7a 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: 29887487ed user: dan tags: trunk) | |
| 14:17 | Fix up a branch in sqlite3ValueFromExpr() so that we can achieve full branch test coverage regardless of whether or not SQLITE_ENABLE_STAT2 is used. (check-in: af471ed79f user: drh tags: trunk) | |
| 12:52 | Change the name of the shared-memory file on windows from *-wal-index to *-shm, for consistency with unix. (check-in: 5995cb1508 user: drh tags: trunk) | |
| 11:35 | Modify the merge-sort in wal.c so that it does not use recursion. (check-in: daea6c054c user: dan tags: trunk) | |
|
2010-06-24
| ||
| 19:16 | Add test cases to pager1.test and pagerfault.test. (check-in: 4941e437d2 user: dan tags: trunk) | |
| 18:36 | Revert to allowing a cache spill during writes of multiple pages within a single sector as long as the spill does not require a journal sync and a new journal header. (check-in: 7d83fbae98 user: drh tags: trunk) | |
| 17:37 | Modify ctime.test to work with SQLITE_THREADSAFE=2. (check-in: c6db3b3031 user: dan tags: trunk) | |
| 14:52 | Disable memory-pressure induced cache spill during savepoint rollback. (check-in: a55eb4c3e9 user: drh 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: 7aac9ad6dd user: dan tags: trunk) | |
| 02:46 | Make sure the wal-index reader detects an incorrect version number even if it had to hold a lock in order to read the wal-index. Also, expand and enhance various comments in wal.c. (check-in: 2e6a462ceb user: drh tags: trunk) | |
|
2010-06-23

| 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: 8d0f8a7f70 user: dan tags: trunk) | |
| 15:18 | Fix the xCurrentTimeInt64 interface on windows. It was off by a factor of 10. (check-in: 51ef43b9f7 user: drh tags: trunk) | |

| 17:26 | Add tests to pager1.test and pagerfault.test. (check-in: f5df83fd87 user: dan tags: experimental) | |
| 15:10 | Change the unix VFS to always allocate shared-memory using a file in the same directory as the database. Otherwise, a chroot might cause different processes to use different shared memory files resulting in database corruption. (check-in: 2241788bc8 user: drh tags: trunk) | |
| 11:30 | Add tests to pager1.test and pagerfault.test. (check-in: 58c0b5bfed 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: ce0a4a9b5f 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: 077b0e5bcd user: dan tags: experimental) | |
|
2010-06-17
| ||
| 17:05 | Apply [b9b11855e8] (the alternate fix to [fc62af4523]) to the trunk. (check-in: 9a949a3a5c user: dan tags: trunk) | |
| 16:44 | Merge trunk change [7c3a86b9c7]. (check-in: bd7bc4e0e2 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: b9b11855e8 user: dan tags: experimental) | |
| 16:08 | Fix the tkt-fc62af4523.test to work around non-randomness of the randomblob() function when in testing mode. (check-in: 7c3a86b9c7 user: drh tags: trunk) | |

| 06:19 | Merge fix [f80c3f922a] with experimental changes. (check-in: 20133e9ca9 user: dan tags: experimental) | |
| 02:13 | Bug fix: Only trust the database size number at offset 28 if the change counter at offset 24 matches the version number counter at offset 92. This prevents corruption in the case of two applications writing to the database where one is an older version of SQLite and the other is a newer version. (check-in: f80c3f922a user: drh tags: trunk) | |
|
2010-06-16
