20:23
The expression list on the RHS of an IN operator can no longer be empty because an empty expression list is now optimized out by changes in check-in [c288ac644d0bf]. Therefore add ALWAYS() macros around tests for the expression list being non-empty. (check-in: fd130ae56c user: drh tags: trunk)
19:31
Additional test cases and evidence marks for the empty RHS bug on the IN operator - ticket [80e031a00f45dca877] (check-in: 6851c517ac user: drh tags: trunk)

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

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)

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)

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

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)
13:24
Add a coverage test to pagerfault.test. (check-in: b58db67e97 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: 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
22:00
Fix and/or improve comments in wal.c. No code changes. (check-in: ee9991be08 user: drh tags: trunk)
19:27
Add test case for SQLITE_FULL errors to pagerfault.test. Remove a NEVER macro in pager.c that this hits. (check-in: 3e9680c4c1 user: dan tags: trunk)

Include the SOURCE_ID value in the log messages output for corruption, misuse, and CANTOPEN errors. (check-in: 1727a81fed user: drh tags: trunk)
17:58
Adjust the shared-memory locking range to account for the new version number values in the wal-index header. (check-in: a6dc0df304 user: drh 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: 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)

Fix an assert() failure that could occur if compiling with OMIT_SHARED_CACHE. (check-in: 3e76a9f2c0 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: 5a5ff4e3e4 user: dan tags: experimental)
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)

18:59
Add tests to pager1.test. (check-in: 582fca8919 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)
11:36
Fix bug in journal2.test. (check-in: c1e04f1d4e user: dan tags: experimental)

10:24
Add test case for [fc62af4523]. (check-in: cccd32c692 user: dan 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
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: bede8c8a14 user: dan tags: experimental)
12:30
Add extra test cases to pager1.test. (check-in: ad3209572d user: dan tags: trunk)

Changes to the way tcl test scripts work. No changes to production code. (Closed-Leaf check-in: 2c5e48a485 user: dan tags: experimental)
12:09
Minor tweaks to the interface documentation - adding hyperlinks. (check-in: 07b2fdd1ce user: drh tags: trunk)

Fix an error in the walfault.test script introduced by the previous check-in. (check-in: a2b9374fc6 user: drh tags: trunk)
18:01
Move the xShmMap method to in between xShmLock and xShmBarrier, since it seems to fit in there logically. (check-in: 58dfd83d8b user: drh tags: trunk)
17:09
Merge the experimental shared-memory mmap-by-chunk changes into the trunk. (check-in: f295e7ed5f user: drh tags: trunk)
16:16
Add the new xShmMap (formerly xShmPage) to os_win.c. (check-in: 13e7a82422 user: dan tags: experimental)
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: fc0cabc15c user: dan tags: experimental)
11:49
Update some comments in wal.c. No code changes. (check-in: 1ce9c92bff user: dan tags: experimental)
11:18
Change the interface to internal function walGetHash() to make it easier to follow. (check-in: 5e8e2e978e user: dan tags: experimental)
10:30
Add the xShmPage method to the "crash" vfs in test6.c. (check-in: 1008f53644 user: dan tags: experimental)
07:53
Add some fault-injection tests to improve coverage. (check-in: 37b26d125f user: dan tags: experimental)

Adding original art for the new SQLite logo. (check-in: af353bd89e user: drh tags: trunk)
14:07
Add the SQLITE_TESTCTRL_PGHDRSZ verb for sqlite3_test_control() used to get the size of pcache headers for testing purposes. (check-in: 5d694f04fe user: drh tags: trunk)
10:51
Update the test VFS in test_journal.c so that it implements the xCurrentTimeInt64 method. (check-in: ec3b4a7e5d user: drh tags: trunk)
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: 0ce42e7665 user: dan tags: trunk)
01:07
Remove a condition that must always be true. Replace it with an assert(). (check-in: 7abcd54ec0 user: drh tags: trunk)
2010-06-09
19:01
Fix test script problems causing errors in the "inmemory_journal" permutations. (check-in: ea05b7f929 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: 0797b10c0c user: dan tags: trunk)
15:47
Fix for ticket [f973c7ac31]. (check-in: 6eb058dda8 user: dan tags: trunk)
14:45
Shift the meaning of aReadMark[] back so that +1 offset from mxFrame is removed. Add the new READMARK_NOT_USED value (0xffffffff) instead of zero to signal an aReadMark[] that is not in use. (check-in: c576827d55 user: drh tags: trunk)
11:28
Simpler fix for the race condition also fixed by [7c102c7b5f] (check-in: 3c2de82003 user: dan tags: trunk)
11:02
Fix for race condition in WAL locking code. (Closed-Leaf check-in: 7c102c7b5f 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: b072e9f69a 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: ac4cc2574b 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: 95cc976f15 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: 7c33eb5a5a user: dan tags: trunk)
14:28
Refactor some of the global variables and commands used by tester.tcl. (check-in: c2edf8e17f user: dan tags: trunk)
06:11
Add a couple of extra coverage tests for wal.c. (check-in: cfe60254df user: dan tags: trunk)
2010-06-05
19:18
Add further test cases for the logic in sqlite3WalBeginReadTransaction(). (check-in: a49713db39 user: dan tags: trunk)
18:34
Clarify the purpose of a test for a race-condition in sqlite3WalBeginReadTransaction(). (check-in: c041c6a978 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: 394204735a user: dan tags: trunk)
14:42
Mark a condition in wal.c as ALWAYS(). (check-in: 3fe0cc784a user: dan tags: trunk)
11:53
Add extra coverage test cases for wal.c. No changes to production code. (check-in: f9d4ae0e8c user: dan tags: trunk)
2010-06-04
18:38
Clarify an assert in sqlite3WalExclusiveMode(). (check-in: 255850699d user: dan tags: trunk)
17:16
Remove an unnecessary branch from wal.c. (check-in: 8e54786c9a user: dan tags: trunk)
15:59
Add an English language error message to corresponding to SQLITE_PROTOCOL. "locking protocol". (check-in: ca327e32cf 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: 157feba10f 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: b813233d76 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: 02c4040ce2 user: dan tags: trunk)
2010-06-03
19:10
Fix another problem in test_vfs.c. (check-in: df7d59899c user: dan tags: trunk)
18:20
Have test_vfs.c simulate IO errors in xShmLock. (check-in: fcbf7cf189 user: dan tags: trunk)
18:02
Performance fix for winShmClose(). (check-in: ed7774de04 user: drh tags: trunk)
16:58
Add extra tests for removing elements from wal-index hash tables as part of a rollback. (check-in: af3e598ad9 user: dan tags: trunk)
12:35
Delay opening the sub-journal until SQLite actually needs to write data to it. (check-in: c43deb33ae user: dan tags: trunk)
12:09
Remove global variables when compiled with SQLITE_OMIT_WSD (check-in: dd10a547f1 user: drh tags: trunk)
09:25
Enhancements to test_vfs.c and walfault.test. (check-in: ac0de2f39e user: dan tags: trunk)
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: eb80ddc665 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: 91cb08ffb6 user: dan tags: trunk)
2010-06-02
20:38
When a lock fails due to an I/O error (not an SQLITE_BUSY) then the checkpoint should fail. (check-in: c6eb0a2727 user: drh tags: trunk)
18:59
Fix a problem with rolling back to a savepoint opened before the writer decided to wrap the log file. (check-in: 6b4aed6aae 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: cb571c1b71 user: dan tags: trunk)
16:40
Added implementation of vfslog_time() for Windows testing. (check-in: b3109f85bd user: shaneh tags: trunk)
16:39
Updated wal2.test for windows testing. (check-in: c3606f3985 user: shaneh tags: trunk)
15:59
Make sure the directory used by os_unix.c for shared-memory files is always the same, regardless of individual client permissions and environment variable settings. (check-in: f97bd520f0 user: drh tags: trunk)
15:43
When walTryBeginRead() encounters an I/O error trying to set a lock (as opposed to SQLITE_BUSY) be sure to propagate that error back up the call stack. (check-in: aa2c2b67a7 user: drh tags: trunk)
14:45
Changes to make WAL more robust against SHM locking failures and OOM errors. (check-in: ebf4041383 user: drh tags: trunk)
14:43
In the rowhash.test, make sure global variables are cleared prior to use. (check-in: 28efe0a404 user: drh tags: trunk)
12:58
Undo one of the "const" markers from the previous check-in because the value needs to be changable, even if it is not actually ever changed in the current implementation. (check-in: c24ac3563f user: drh tags: trunk)
05:53
Add some 'const' markers to static data that is really constant. (check-in: e7073e23b8 user: dan tags: trunk)
2010-06-01
21:02
The shared-memory used by WAL on linux now really is shared memory in /dev/shm. On other unix flavors, the file is in a temporary directory rather than in the same directory as the database. (check-in: fc18c4aadb user: drh tags: trunk)
19:15
Changes to the way faults are injected into xShmXXX VFS calls. (check-in: 716d99f392 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: b627e15368 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: b1abfaaf53 user: dan tags: trunk)
15:24
The incremental checkpoint feature is not perfect yet, but it is working well enough to merge it into the trunk. (check-in: 1d3e569e59 user: drh tags: trunk)
14:30
Merge with [15abbc3416]. (Closed-Leaf check-in: f4b9003a2d 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: ce64496509 user: dan tags: wal-incr-ckpt)
13:17
Fix a bug introduced by the previous check-in but only seen if SQLITE_ENABLE_EXPENSIVE_ASSERTS is turned on. (check-in: 9c9ec8994b user: drh tags: wal-incr-ckpt)
12:58
Fix an off-by-one boundary-value issue in walCleanupHash(). (check-in: f039552e63 user: drh tags: wal-incr-ckpt)
11:08

Change the checksum used in WAL files so that each frames checksum depends on the content of the WAL header and all frame headers and content up to and including the frame to which the checksum is attached. (check-in: 8a53f12c83 user: dan tags: trunk)
13:28
Make sure a WAL frame of all zeros is detected as an invalid frame. (check-in: 02d99ad4b5 user: drh tags: trunk)

Prohibit backup if the destination is using WAL and has a different page size from the source. (check-in: 7bd44794c4 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: 2ac5d96c8e 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: 208e7d5d3a user: drh tags: trunk)
03:39
Do not attempt to modify the page_size when running VACUUM on a WAL database. (check-in: 58a1a59be8 user: drh tags: trunk)

Get the previous mutex fix working with SQLITE_DEBUG and with the amalgamation. (check-in: df19928f7e 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: 451fd17575 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: 4016b42228 user: drh 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: ea09ff3791 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: 43b5b07f0d 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: 7fecd21f45 user: dan tags: trunk)
14:32
Use VFS method xCurrentTimeInt64 instead of xCurrentTime when it is available. Provide an implementation of xCurrentTimeInt64 for os_unix.c. (check-in: ab77b3ae6d user: drh tags: trunk)
14:08
Merge the write-ahead-logging changes into the trunk. (check-in: de9ae443cc user: drh tags: trunk)
14:05
If the sqlite3_wal_checkpoint() API is passed a NULL pointer in place of a database name, attempt to checkpoint all attached databases. (Closed-Leaf check-in: 27a5c09ce8 user: dan tags: wal)

2010-05-01
20:17

Change the SHM VFS logic in os_unix.c so that it does not hold an exclusive lock n the mapped memory when also holding a CHECKPOINT lock. This improves concurrency between readers and checkpointers. (check-in: 8660cda6f8 user: drh tags: wal)
17:28
Remove some obsolete debugging parameters. (check-in: a012aed498 user: drh tags: wal)

16:41
Fix a problem in the previous commit. Both unixShm.lockState and unixShm.readLock should be set to READ when downgrading from a WRITE to a READ lock (check-in: 90119fecbc user: dan tags: wal)
16:38
Fix a bug whereby upgrading from a READ_FULL to a WRITE lock, and then back to a read lock was dropping all WAL locks. (check-in: 55f5af5e17 user: dan tags: wal)
16:24
