2010-10-01
20:45
Backport the RTree implementation from the trunk into the 3.6.23 branch. The code for the application-defined query boxes is still present but is disabled. The reason for this backport is to take advantage of recent enhancements to robustness to database corruption. (check-in: 854b23c1 user: drh tags: branch-3.6.23)
2010-08-24
12:05
Pull the incremental_vacuum bug fix ([255f1eefa373153942c67b18b]) and the R-tree segfault bug fix ([7f2f71cc9e3c39093f09231f44]) into the 3.6.23 branch. Increase the version number to 3.6.23.3. (check-in: bcbdecd8 user: drh tags: branch-3.6.23)

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)
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: 2241788b user: drh tags: trunk)
11:30
Add tests to pager1.test and pagerfault.test. (check-in: 58c0b5bf 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)
16:08
Fix the tkt-fc62af4523.test to work around non-randomness of the randomblob() function when in testing mode. (check-in: 7c3a86b9 user: drh tags: trunk)
11:36
Fix bug in journal2.test. (check-in: c1e04f1d user: dan tags: experimental)

10:24
Add test case for [fc62af4523]. (check-in: cccd32c6 user: dan tags: trunk)
06:19
Merge fix [f80c3f922a] with experimental changes. (check-in: 20133e9c 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: f80c3f92 user: drh tags: trunk)
2010-06-16
19:48
Merge in changes up to and including the 3.6.23.1 release. (check-in: 21ca87f6 user: drh tags: apple-osx)
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

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)
12:09
Minor tweaks to the interface documentation - adding hyperlinks. (check-in: 07b2fdd1 user: drh tags: trunk)
11:21

2010-06-14
18:06
Fix an error in the walfault.test script introduced by the previous check-in. (check-in: a2b9374f 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: 58dfd83d user: drh tags: trunk)
17:09
Merge the experimental shared-memory mmap-by-chunk changes into the trunk. (check-in: f295e7ed user: drh tags: trunk)
16:16
Add the new xShmMap (formerly xShmPage) to os_win.c. (check-in: 13e7a824 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: 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)
10:30
Add the xShmPage method to the "crash" vfs in test6.c. (check-in: 1008f536 user: dan tags: experimental)

2010-06-12
12:02
Fix some problems with handling IO errors on the experimental branch. (check-in: eade8bc2 user: dan tags: experimental)
2010-06-11

2010-06-10
16:25
Adding original art for the new SQLite logo. (check-in: af353bd8 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: 5d694f04 user: drh tags: trunk)
10:51
Update the test VFS in test_journal.c so that it implements the xCurrentTimeInt64 method. (check-in: ec3b4a7e 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: 0ce42e76 user: dan tags: trunk)
01:07
Remove a condition that must always be true. Replace it with an assert(). (check-in: 7abcd54e user: drh 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)
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: c576827d user: drh tags: trunk)
11:28
Simpler fix for the race condition also fixed by [7c102c7b5f] (check-in: 3c2de820 user: dan tags: trunk)
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
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)
18:02
Performance fix for winShmClose(). (check-in: ed7774de user: drh 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)
12:09
Remove global variables when compiled with SQLITE_OMIT_WSD (check-in: dd10a547 user: drh tags: trunk)
09:25
Enhancements to test_vfs.c and walfault.test. (check-in: ac0de2f3 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: 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
20:38
When a lock fails due to an I/O error (not an SQLITE_BUSY) then the checkpoint should fail. (check-in: c6eb0a27 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: 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)
16:40
Added implementation of vfslog_time() for Windows testing. (check-in: b3109f85 user: shaneh tags: trunk)
16:39
Updated wal2.test for windows testing. (check-in: c3606f39 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: f97bd520 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: aa2c2b67 user: drh tags: trunk)
14:45
Changes to make WAL more robust against SHM locking failures and OOM errors. (check-in: ebf40413 user: drh tags: trunk)
14:43
In the rowhash.test, make sure global variables are cleared prior to use. (check-in: 28efe0a4 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: c24ac356 user: drh 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
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: fc18c4aa user: drh tags: trunk)
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)
15:24
The incremental checkpoint feature is not perfect yet, but it is working well enough to merge it into the trunk. (check-in: 1d3e569e user: drh 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)
13:17
Fix a bug introduced by the previous check-in but only seen if SQLITE_ENABLE_EXPENSIVE_ASSERTS is turned on. (check-in: 9c9ec899 user: drh tags: wal-incr-ckpt)
12:58
Fix an off-by-one boundary-value issue in walCleanupHash(). (check-in: f039552e user: drh 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)
01:08
Comment edits and cleanup in wal.c. No functional code changes. (check-in: e8e666ab user: drh tags: wal-incr-ckpt)
00:28
Attempt to get the filectrl.test script running. (check-in: e46a8f2b user: drh tags: wal-incr-ckpt)
00:03
Fix os_unix.c so that it will compile and build on a Mac. (check-in: bc707c83 user: drh tags: wal-incr-ckpt)
2010-05-31
20:28
Fix issues with locking_mode=EXCLUSIVE in WAL. (check-in: 8deba0ce user: drh tags: wal-incr-ckpt)
18:24
Add an "isInit" field in the wal-index header that must be non-zero for a valid header. Use this to detect an uninitialized wal-index. (check-in: a16fde19 user: drh tags: wal-incr-ckpt)
16:56
Fix an inconsistent #ifdef in wal.c. Fix os_unix.c so that it does not allow moving an SHM lock directly exclusive to shared without going through unlocked. (check-in: 552658da user: drh tags: wal-incr-ckpt)
16:41
Avoid dropping the checkpoint lock after a recovery run as a precursor to a checkpoint operation. (check-in: cc25cfa0 user: dan tags: wal-incr-ckpt)
16:17
Zero the checkpoint header as the last step of successful WAL recovery. Avoid an unnecessary lock/unlock in WalBeginReadTransaction. (check-in: db3509c5 user: dan tags: wal-incr-ckpt)
16:10
Get the new xShmLock interface design working on os_win.c. (check-in: 149a7082 user: drh tags: wal-incr-ckpt)
14:39
Make sure WAL alway requests enough shared-memory space. (check-in: 138f1283 user: drh tags: wal-incr-ckpt)
14:28
Remove the tests that enable tracing based on the existance of the "vdbe_*" files when in SQLITE_DEBUG mode. (check-in: cdbb4e7c user: drh tags: wal-incr-ckpt)
14:18
Update another test case in wal.test. (check-in: 99fde69e user: dan tags: wal-incr-ckpt)

Do not fail a checkpoint just because active readers prevent backfill. (check-in: 9aa4243e user: drh tags: wal-incr-ckpt)
12:15
Add WALTRACE() macros to help with debugging and analysis. (check-in: 765c3318 user: drh tags: wal-incr-ckpt)

WAL runs but quickly deadlocks. (check-in: ace58acb user: drh tags: wal-incr-ckpt)
2010-05-30
19:55
Initial code for incremental checkpoint in WAL mode. This check-in compiles on unix and runs as long as you do not engage WAL mode. WAL mode crashes and burns. Consider this check-in a baseline implementation for getting the new capability up and running. (check-in: ef3ba7a1 user: drh tags: wal-incr-ckpt)
2010-05-29

15:06
Change the semantics of xShmGet() such that it will never increase the size of shared memory. xShmSize() must be used to grow the size of shared memory. A shared memory segment size cannot be shrunk (except by dropping it). (check-in: 72de0073 user: drh tags: trunk)
2010-05-25
15:53
Updated header comments in wal.c. No functional code changes. (check-in: 687632a6 user: drh tags: trunk)

Fix the wal2.test script so that it works in auto_vacuum mode. (check-in: 6a818afb user: drh tags: trunk)
13:57
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: 8a53f12c user: dan tags: trunk)
13:28
Make sure a WAL frame of all zeros is detected as an invalid frame. (check-in: 02d99ad4 user: drh tags: trunk)

Fix up test_osinst.c to work with SQLITE_OMIT_VIRTUALTABLE. (check-in: 51fd3815 user: drh tags: trunk)
10:39
Change the WAL file format to support two kinds of checksums - one that is fast to calculate on little-endian architectures and another that is fast on big-endian architectures. A flag in the wal-header indicates which the file uses. (check-in: 65ba804d user: dan tags: trunk)
2010-05-22
08:22
Add a couple of missing methods to test_osinst.c.. (check-in: 5c9e9c06 user: dan tags: trunk)

2010-05-21
19:15
Fix another bug in walClearHash(). (check-in: 40f80ffe user: dan tags: trunk)

Fix the wal-index header read routine so that it correctly detects a zero header as being malformed and in need of a wal-index rebuild. (check-in: 1a4eb3a3 user: drh tags: trunk)
2010-05-20
23:51
Add a new xShmBarrier method to the VFS - a shared-memory fence operation. Implement the same in both unix and win32. Use it to make the WAL subsystem more robust. (check-in: 1bd011c9 user: drh tags: trunk)
21:21
Make use of the extra information in the WAL header and frame header to enhance robustness. (check-in: 9580ecb7 user: drh tags: trunk)
16:45
Convert the wal-header and frame-header to 24 bytes. Extra information in both headers is designed to enhance robustness after crashes, though the extra information is currently unused. This is a snapshot of a work in progress. (check-in: 66970643 user: drh tags: trunk)
2010-05-19
23:41
Merge WIN32 WAL support into trunk. Still some issues with locking to resolve. (check-in: 43377663 user: shaneh tags: trunk)

Update the wal-index hash format so that hash-table space is reused following a rollback, thus preventing hash table overflows. Add assert()s to verify that hash tables do not overfill. Further refactoring of the wal-index code. (check-in: ada9a8c7 user: drh tags: trunk)
18:01
Refactoring of the WalIterator implementation. (check-in: b5b60fdc 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)

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)

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)

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)

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)

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)

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)

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)

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)

00:05
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)
2010-05-04
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)

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)

2010-04-12
20:54
Add e_fts3.test to the set of tests excluded from the inmemory_journal exclusion list, since it does simulated OOM errors which trigger I/O errors and SQLite is unable to recover from I/O errors without a persistent journal. (check-in: e7e7127f user: drh tags: trunk)
19:44
Recent changes cause the xSync method of the memory journal implementation to be used, so remove the assert(0). (check-in: 1f2cb940 user: drh tags: trunk)

Change a C++ style comment in os_unix.c to use normal C style commenting. (check-in: 7a193309 user: dan tags: trunk)
10:59
Fix for [e9a9fde1f4]. When opening an existing rtree, determine the node size by inspecting the root node of the r-tree structure (instead of assuming it is a function of the page-size). (check-in: ebc9433f user: dan tags: trunk)
2010-02-15
18:03
Fix the ALTER TABLE RENAME command so that it converts FOREIGN KEY constraints in ATTACH-ed and in TEMP tables as well as in the main database. Ticket [13336e9c3c8c3f]. (check-in: ab197d0a user: drh tags: trunk)
16:54

05:34
Delete output files if this is a failed run.

Otherwise, the fail will stop a Makefile from progressing, but if you immediately run the build again, Make will think the output files are up to date, since they are newer (albeit incomplete/incorrect). (check-in: e38c08d9 user: icculus tags: lemon-update-2010)

05:19
Added %expect directive, to consider a certain number of conflicts "correct."

13:42
Remove the "proc zeroblob" implementation from incrvacuum2.test. It is no longer required as of (6906) and, as #3988 points out, unreliable. (CVS 6936) (check-in: 03153831 user: danielk1977 tags: trunk)
11:46

04:12
Add assert() statements to more tightly constrain the state of pager.c. Remove the three pager*.test scripts since they violate the constraints asserted above by modifying the state of the system in ways that it cannot be modified in a live system. (CVS 6933) (check-in: 3b6d370e user: drh tags: trunk)
00:13
Remove two more overzealous assert() statements. (CVS 6932) (check-in: 788aa9dd user: drh tags: trunk)

17:11
Modify various routines inside btree.c to take a pointer to the return-code as a parameter and to no-op if the return-code storage location already contains a non-zero code. (CVS 6911) (check-in: 7dcf2a78 user: drh tags: trunk)
12:33
Use an ALWAYS() on a conditional in btmutex.c that is always true. (CVS 6910) (check-in: 609022ca user: drh tags: trunk)

11:52
When the asynchronous IO backend opens a file with the EXCLUSIVE flag set, make sure only a single file-descriptor is opened (not one for reading and one for writing). This change fixes #3978. (CVS 6905) (check-in: 630e669b user: danielk1977 tags: trunk)

2009-07-15
18:15
Fix a potential database corruption following DROP TABLE when the pending byte page corresponds to a ptrmap page. This situation cannot happen in a real deployment - but it still needs to be fixed. (CVS 6897) (check-in: 6242db39 user: drh tags: trunk)
17:25
Simplifications to btree.c in support of structural testing. Renamed the "skip" field of the BtCursor object to "skipNext" to make it easier to search for places where it is used. (CVS 6896) (check-in: d3897235 user: drh tags: trunk)
16:30
Remove an assert() from vdbeaux.c that might not be true if the database file is corrupt. (CVS 6895) (check-in: a42dc51e user: drh tags: trunk)
11:26

2009-07-13
15:52
Remove the SQLITE_CommitBusy flag. This was an attempt to block recursion on the sqlite3_commit_hook() interface. But such recursion is explicitly disallowed, so the flag is pointless. (CVS 6889) (check-in: 1c2bfc43 user: drh tags: trunk)
13:18
Change an unreachable condition in btree.c to a NEVER(). (CVS 6888) (check-in: 9f800e11 user: danielk1977 tags: trunk)

Simplifications to btree.c to help facilitate coverage testing. (CVS 6884) (check-in: dfb146ef user: drh tags: trunk)
02:31
When an OOM fault occurs while moving a page for autovacuum in an in-memory database, be sure to undo the page move prior to returning the error, to avoid corrupting the in-memory database file. (CVS 6883) (check-in: d0964b93 user: drh tags: trunk)
2009-07-11

Remove another unreachable branch from btree.c. (CVS 6878) (check-in: b0853100 user: danielk1977 tags: trunk)
06:55
Modify the integrity-check code so that each b-tree page inspected is reinitialized while doing so, even if an initialized copy exists in the cache. This prevents an assert from failing when running integrity_check on a corrupt database. (CVS 6877) (check-in: 709576c6 user: danielk1977 tags: trunk)
05:06
Remove unreachable condition from btree.c. (CVS 6876) (check-in: 47b40fef user: danielk1977 tags: trunk)

13:25
Fix two faulty assert() statements btree. (It was possible for the assertions to be false given a corrupt database file as input.) (CVS 6872) (check-in: 9403f04d user: drh tags: trunk)
11:36
Remove an unused branch from btree.c. (CVS 6871) (check-in: 45efb78a user: danielk1977 tags: trunk)
08:27
In btree.c, have setSharedCacheLock() assume that the b-tree is sharable instead of checking to see if it is. The caller has already performed this check. (CVS 6870) (check-in: 3190eefd user: danielk1977 tags: trunk)
05:07
Restore (btree_set_cache_size) to test3.c. This is used on unix for the tcl "crash tests". Make some functions no longer used outside of btree.c static. (CVS 6869) (check-in: 1d96ce8c user: danielk1977 tags: trunk)
03:20
removed the test function sqlite3BtreeFlags() (test code only); (CVS 6868) (check-in: 579ba6c8 user: shane tags: trunk)

Improvements to corrupt database detection in defragmentPage(). (CVS 6857) (check-in: 87bbc8d6 user: drh tags: trunk)
15:47
Do not load the root-page of a b-tree table/index when opening a cursor. Instead, allow it to be loaded when the cursor is first used (in function moveToRoot()). Also move the root-page flags sanity checks that were a part of the OP_OpenRead/OpenWrite opcodes into the moveToRoot() function. (CVS 6856) (check-in: 06dcfe72 user: danielk1977 tags: trunk)
13:56
If an error occurs in PagerBegin(), call pager_end_transaction() to reset the internal state of the pager object. (CVS 6855) (check-in: ea7ed166 user: danielk1977 tags: trunk)
11:39

02:44
Simplifications to btree.c and vdbeaux.c in support of structural coverage testing. (CVS 6853) (check-in: fc2a40a9 user: drh tags: trunk)
2009-07-06
21:54
Fix the pager so that it remembers the name of the journal for an in-memory database as an empty string. This is important when committing a multi-database transaction that includes one or more attached memory databases. (CVS 6852) (check-in: 31a5e819 user: drh tags: trunk)
19:03
Fix the backup logic so that it detects a failure to sqlite3BtreeUpdateMeta() and reports that failure back up to the top level. (CVS 6851) (check-in: 471b92f2 user: drh tags: trunk)
18:56
Make the sqlite3BtreeMoveto function static, since it is only used from within btree.c. Remove unused function lockBtreeWithRetry from btree.c. (CVS 6850) (check-in: 30d5ec62 user: danielk1977 tags: trunk)
00:44
Simplifications and comment cleanup in vdbeaux.c. (CVS 6849) (check-in: 1636e783 user: drh tags: trunk)

17:23
Remove an unused variable from the test code in test3.c. (CVS 6843) (check-in: 9e35bec9 user: drh tags: trunk)
17:09
Add a version of the Lemon parser template "lempar.c" to the src/ subfolder. This new parser template contains a couple of NEVER() macros that disable tests that are needed for general grammars but not for the specific grammar used by SQLite. SQLite builds with the modified lempar.c. (CVS 6842) (check-in: d426cc64 user: drh tags: trunk)
16:25
Simplify the way the read-uncommitted flag is handled to facilitate test coverage. (CVS 6841) (check-in: e2112d61 user: danielk1977 tags: trunk)

2009-07-02
18:40
Fix to sqlite3AuthRead to accommodate "new" or "old" references that are used in a context where a column reference may also be used (i.e. "SELECT new.
17:21
When a b-tree transaction is committed when there are open cursors, downgrade shared-cache write-locks to read-locks instead of relinquishing all locks. Fix for #3942. (CVS 6837) (check-in: 611e704f user: danielk1977 tags: trunk)
07:47
Cause opening a transaction on a sharable b-tree module automatically obtain a read-lock on page 1. This means there is no way for sqlite3BtreeGetMeta() to fail. (CVS 6836) (check-in: e3c055f1 user: danielk1977 tags: trunk)
05:23
Fix for compilation with OMIT_AUTOVACUUM defined. Ticket #3940. (CVS 6835) (check-in: 8f0591ae user: danielk1977 tags: trunk)
2009-07-01
18:09
Change to test code and scripts allowing memsys3 to be tested using a build that has both memsys3 and memsys5 enabled. (CVS 6834) (check-in: a00aeec2 user: danielk1977 tags: trunk)
18:04

16:12
Report an error if a USING or ON clause is specified following a from-list element that is not to the right of a join operator. Fix for #3846. (CVS 6832) (check-in: 29b48972 user: danielk1977 tags: trunk)
14:56
Do not ignore alias "a" in a query of the form "SELECT ... FROM (...) AS a" Fix for #3935. Also expand upon (6751) to fix some similar obscure memory leaks. (CVS 6831) (check-in: 42f9d1e5 user: danielk1977 tags: trunk)
2009-06-29
06:00
Cause incremental-blob read/write operations lock shared-cache tables in the same way as normal SQL read/writes. Add complex assert statements to make sure tehe correct shared-cache locks are held when accessing the database. Eliminate some redundant checks from btree.c. (CVS 6830) (check-in: f17ef378 user: danielk1977 tags: trunk)
2009-06-27
14:10
Version 3.6.16 (CVS 6829) (check-in: ff691a6b user: drh tags: trunk, release)

Fix an instance where sqlite3JumpHere() might be called with a negative address following an OOM fault. (CVS 6828) (check-in: 49f22e55 user: drh tags: trunk)
00:48
Fix a bug in sqlite3_realloc() - if called with a size of more than 2147483392 it returns 0 but it also releases the prior allocation. (CVS 6827) (check-in: 653df0af user: drh tags: trunk)
2009-06-26
18:35
Remove incorrect NEVER() macros from malloc.c. The allocations can be exceeded using sqlite3_malloc() and sqlite3_realloc(). (CVS 6826) (check-in: 0d345e59 user: drh tags: trunk)
16:32
Removed a few compiler warnings under MSVC. (CVS 6825) (check-in: f01a9fc3 user: shane tags: trunk)
15:14
Remove the priorNewRowid field from the sqlite3 structure. Use the last_insert_rowid as the initial value when searching for a new random rowid in the OP_NewRowid opcode. (CVS 6824) (check-in: 96729b2d user: drh tags: trunk)
14:17
Skip a couple tests requiring working 64bit int support on platforms without that support. Test code change only. (CVS 6823) (check-in: d8c8145c user: shane tags: trunk)
14:04
When sqlite3VdbeAddOp() fails due to an OOM fault, return an address of 1 rather than zero so that there appears to always be a prior instruction. This prevents a negative jump-to address computation in where.c following an OOM fault. (CVS 6822) (check-in: fe02339c user: drh tags: trunk)
12:30
Fix a test script problem in exclusive.test. (CVS 6821) (check-in: a52ef5a4 user: danielk1977 tags: trunk)
12:15
Fix the new pager.c changes so that they compile with IOTRACE defined. Fix an out-of-order variable definition in vdbeaux.c. (CVS 6820) (check-in: ac145028 user: drh tags: trunk)
10:39
Another change to test_journal.c to account for (6817). Again, only test code has changed. (CVS 6819) (check-in: 58884b6c user: danielk1977 tags: trunk)
09:01
Update test_journal.c to account for (6817). Changes to test code only. (CVS 6818) (check-in: 542ee8cc user: danielk1977 tags: trunk)
07:12
Avoid writing the 8-byte journal-header magic until the journal-header is synced. In persistent journal-mode, this prevents any old content that follows an unsynced journal-header from being interpreted as part of the rollback journal. (CVS 6817) (check-in: a5ecffcf user: danielk1977 tags: trunk)
2009-06-25
16:11
Fix a problem with a return code being ignored in insertCell(). (CVS 6816) (check-in: bb5f1c01 user: danielk1977 tags: trunk)
11:50
Get the notify2.test running again by removing an ALWAYS() that was mistakenly inserted and by taking care not to report corruption following an SQLITE_LOCKED failure during schema parsing. (CVS 6815) (check-in: 6e9140a7 user: drh tags: trunk)
09:40
Replace an "if" condition that is always true in btree.c with an assert(). (CVS 6814) (check-in: daadbd9a user: danielk1977 tags: trunk)
01:47
Improved handling of oversize string and blob errors. Other simplifications in support of full coverage testing. (CVS 6813) (check-in: 8b340766 user: drh tags: trunk)
2009-06-24
13:16
Remove an ALWAYS() macro from vdbe.c that sometimes fails on thread tests. (CVS 6812) (check-in: 52eac078 user: drh tags: trunk)
13:13
Disable the new malloc-37 test when locking_mode==exclusive. The test basically works, but sometimes reports "database is locked" instead of "out of memory" and that messes up the error reporting. (CVS 6811) (check-in: 3b8f9dec user: drh tags: trunk)
11:08
Remove a declaration of the sqlite3Assert() function that was deleted by the previous check-in. (CVS 6810) (check-in: ee20b6a2 user: drh tags: trunk)
10:26
Remove the sqlite3Assert() function. The ALWAYS() and NEVER() macros call assert() directly when compiled with SQLITE_DEBUG. (CVS 6809) (check-in: d8fc373f user: drh tags: trunk)
05:40
Simplify things by rolling the functionality of balance_shallower() into balance_nonroot(). (CVS 6808) (check-in: 11750c6a user: danielk1977 tags: trunk)
2009-06-23
20:28
Enhance autoincrement so that it works with triggers that also do autoincrement inserts, even multiple inserts into the same table. Ticket #3928 (CVS 6807) (check-in: 1330993d user: drh tags: trunk)
16:40
Remove a condition from balance_nonroot() that is always true. (CVS 6806) (check-in: c5dc80e6 user: danielk1977 tags: trunk)
15:43
Call balance_shallower() from balance_nonroot() instead of from balance(). This simplifies coverage testing a bit. (CVS 6805) (check-in: da9893e2 user: danielk1977 tags: trunk)
14:39
Update the configure script for version 3.6.16 (CVS 6804) (check-in: b614e554 user: drh tags: trunk)

Simplifications to vdbe.c to promote better test coverage. (CVS 6802) (check-in: 3ffc93d7 user: drh tags: trunk)
11:53
Add a test to verify that #3929 is fixed. (CVS 6801) (check-in: 16c1ae9b user: danielk1977 tags: trunk)
11:22
Fix a failing assert in btree.c. The same bug was causing a spurious SQLITE_CORRUPT return when compiled without SQLITE_DEBUG. (CVS 6800) (check-in: 47ec8749 user: danielk1977 tags: trunk)
2009-06-22
19:05
Simplifications to vdbe.c and it service routines in support of coverage testing. (CVS 6799) (check-in: 308f2e61 user: drh tags: trunk)
18:03
Remove a condition that is always true from btree.c. (CVS 6798) (check-in: 3ec8b37a user: danielk1977 tags: trunk)
12:05
Make sure sqlite3BtreeCreateTable() returns an error code if the largest rootpage field is invalid in auto_vacuum mode. Update file-format comments to describe all of the "meta" values. (CVS 6797) (check-in: bda38f5e user: drh tags: trunk)
11:10
More simplifications to vdbe.c. Remove a NEVER() from vdbe.c that is possible after all. (CVS 6796) (check-in: c8f009bd user: drh tags: trunk)
05:43
If an OOM error occurs just after obtaining a shared lock on the database file, release the lock before returning. (CVS 6795) (check-in: 971a9650 user: danielk1977 tags: trunk)
00:55
Simplifications to vdbe.c in support of coverage testing. (CVS 6794) (check-in: 16680f05 user: drh tags: trunk)
2009-06-20
18:52
When recovering from the error-state in pagerSharedLock(), do not search for a hot-journal in the file-system if the pager is configured to use an anonymous temp file as the journal. (CVS 6793) (check-in: 4b46805c user: danielk1977 tags: trunk)
11:54
If after obtaining an exclusive lock to rollback a hot-journal file it is found that the journal file has been deleted, do not return an SQLITE_BUSY error. Just downgrade the lock and continue with the current operation. This eliminates a spurious SQLITE_BUSY error caused by a race condition. (CVS 6792) (check-in: 9a066600 user: danielk1977 tags: trunk)
2009-06-19
22:50
Improved documentation on the VFS methods. Ticket #3925. (CVS 6791) (check-in: f66fc771 user: drh tags: trunk)

17:50
If a call is made to sqlite3PagerAcquire when there are no outstanding references to any pages and the pager is in the error-state, try to exit the error-state at this point. Previously this was only attempted if the pager was configured to use exclusive mode. (CVS 6788) (check-in: 62db08bc user: danielk1977 tags: trunk)
16:44
Make sure group_concat() ignores initial NULL values. (CVS 6787) (check-in: 90c3b23c user: drh tags: trunk)

2009-06-17
22:50
Avoid an assertion fault if an out-of-memory error occurs while trying to run the string-concatentation operator on a zero-blob. (This is an absurd thing to do, but even so, we still should not fault.) (CVS 6778) (check-in: 0def0b76 user: drh tags: trunk)
21:42
Fix a problem in vdbe.c that could cause a double-free of memory if the SQLITE_LIMIT_LENGTH is changed after a statement is prepared but before it is run. Also remove debugging statements from tkt3841.test. (CVS 6777) (check-in: 3d7327fd user: drh tags: trunk)
16:20
Use caution to avoid integer overflow when doing real to integer affinity operations. Ticket #3922. (CVS 6776) (check-in: 39255946 user: drh tags: trunk)

2009-06-16
17:49
Changes sqlite3_prepare_v2() (and related routines) so that if it fails due to a missing table and the schema is out of date, it retries once before returning SQLITE_SCHEMA. Other changes to prepare.c to facilitate coverage testing. (CVS 6769) (check-in: 256ec3c6 user: drh tags: trunk)
16:50
Changes to balance_nonroot() and BtreeDelete() to simplify delete operations and reduce stack/heap usage while balancing b-tree structures. (CVS 6768) (check-in: 092b276e user: danielk1977 tags: trunk)

Additional updates to the symbol resolver and expression tree walker to facilitate test coverage. (CVS 6764) (check-in: a49c2d4b user: drh tags: trunk)
20:45
Changes to allow a clean compile with no floating-point instructions generated when SQLITE_OMIT_FLOATING_POINT is used. (CVS 6763) (check-in: 1591b832 user: drh tags: trunk)

2009-06-12
17:46
Change lemon so that it does not generate yytestcase() macros on destructor cases since destructors are commonly unreachable in a reasonable grammar. For the reduce-rule switch, gather all no-ops into the "default:" case. (CVS 6757) (check-in: caebfe82 user: drh tags: trunk)
15:47
The previous check-in ((6755)) put in more yytestcase() macros than are called for. This check-in addresses that problem. (CVS 6756) (check-in: a5b182f9 user: drh tags: trunk)
13:53
The lemon parser generator now inserts yytestcase() macros on reduce action and on each destructor, to verify that all have been executed. yytestcase() is a no-op by default but can be set to something more useful inside of %include. (CVS 6755) (check-in: fe9c9177 user: drh tags: trunk)
12:50
In lemon: omit unused entries from the end of the yyFallback array. (CVS 6754) (check-in: 9cfbe2ba user: drh tags: trunk)

Honor the SQLITE_OPEN_READONLY flag even on a :memory: or temporary database, even though such a database is pointless. Ticket #3908. (CVS 6748) (check-in: 73ba841a user: drh tags: trunk)
17:04
Add an ALWAYS() to a conditional in where.c. (CVS 6747) (check-in: 1fdb3e1e user: drh tags: trunk)

2009-06-10
19:33
Do not let the reverse_unordered_selects pragma force the use of an index that would not otherwise be used. Ticket #3904. Also: remove an test which is always true. (CVS 6745) (check-in: 78a391dc user: drh tags: trunk)
11:07
Remove a NEVER() that can sometimes occur on an OOM error. (CVS 6744) (check-in: c27f23bb user: drh tags: trunk)

Minor tweak to balance_quick() to save a few instructions. (CVS 6743) (check-in: 9ace9959 user: danielk1977 tags: trunk)
2009-06-09
19:53
Remove the actual checks that verify that memory pools (such as set up using SQLITE_CONFIG_HEAP) are 8-byte aligned. But document that 8-byte alignment is required. (CVS 6742) (check-in: e9b55ccc user: drh tags: trunk)
18:58
Fix compiler warnings with MSVC build. (CVS 6741) (check-in: 0bd84e73 user: shane tags: trunk)
18:14
Avoid a false failure report in the test scripts caused by the vdbe stack "compression" script. (CVS 6740) (check-in: 9d332989 user: shane tags: trunk)
18:02
Require that the buffer specified by SQLITE_CONFIG_HEAP be 8-byte aligned. (CVS 6739) (check-in: 18b78068 user: drh tags: trunk)
18:01
Changes to tokenize.c to facilitate full coverage testing. (CVS 6738) (check-in: 5e8c48cf user: drh tags: trunk)
15:25
Change savepoint4.test to limit database growth. Otherwise the test can take a very long time to run, depending on the prng. (CVS 6737) (check-in: ed1d4f47 user: danielk1977 tags: trunk)
14:27
Modify mkkeywordhash.c so that it puts the original text of each token in a comment beside the "testcase()" macros. (CVS 6736) (check-in: a7d0817c user: drh tags: trunk)
13:42
Enable cell overflow checking in sqlite3BtreeInitPage() using the compile-time option SQLITE_ENABLE_OVERSIZE_CELL_CHECK. Change the tests so that they recognize different error messages depending on the setting of this macro. (CVS 6735) (check-in: 56bff6eb user: drh tags: trunk)
11:34
Avoid calling fillInCell() to create an internal node intkey cell from balance_nonroot(). A single putVarint() does the same thing more quickly. (CVS 6734) (check-in: 2e5d42ae user: danielk1977 tags: trunk)
10:37
Only do the cell overread checks in sqlite3BtreeInitPage if SQLITE_OVERREAD_CHECK is defined at compile-time. (CVS 6733) (check-in: 49f544eb user: drh tags: trunk)
09:41
Do not clear the MemPage.nFree variable when insertCell() adds an overflow cell to a page. Not doing this means balance_quick() can avoid a call to sqlite3BtreeInitPage(). (CVS 6732) (check-in: 8f1c1f61 user: danielk1977 tags: trunk)
2009-06-08
19:44
Additional comments to clarify the operation of the LIKE optimizer in where.c. (CVS 6731) (check-in: cc9c1217 user: drh tags: trunk)

12:52
Increase the version number to 3.6.15 in preparation for the next release. (CVS 6728) (check-in: 456ea541 user: drh tags: trunk)
2009-06-07

2009-06-06
19:21
Update the error message on one of the corruption tests to account for the fact that we are finding the corruption sooner. (CVS 6726) (check-in: ba9848e7 user: drh tags: trunk)
16:08
Fix an error in the malloc.test test script causing a small buffer overread. (CVS 6725) (check-in: 4d129bee user: danielk1977 tags: trunk)
15:17
Make sure the result of sqlite3VdbeGetOp() is not used as an array following an OOM error, since after (6691) it might be a single-entry dummy opcode. (CVS 6724) (check-in: 127b1398 user: drh tags: trunk)
14:13
When building in debug mode with gcc, force the nullMem variable in function columnMem() to be aligned to an 8-byte boundary. Otherwise an assert() statement may fail. (CVS 6723) (check-in: 3fd6c72d user: danielk1977 tags: trunk)
2009-06-05
18:44
Detect when database corruption causes an attemp to set the pointer map value for a pointer map page and report the corruption. (CVS 6722) (check-in: 3ae4880b user: drh tags: trunk)
17:09
Remove leftover "breakpoint" commands from test scripts. Also remove blank lines at the end of scripts. (CVS 6721) (check-in: 1fef16ec user: drh tags: trunk)
16:46
Do not cast an unsigned int into an int for comparison. (CVS 6720) (check-in: 302ab855 user: drh tags: trunk)
14:17
Take care that a corrupt variable-length integer does not cause 32-bit integer overflow when parsing a record format, nor cause excessively large memory allocations. (CVS 6719) (check-in: 38b20327 user: drh tags: trunk)
2009-06-04
19:06
Earlier detection of freelist corruption in the page allocation routines. (CVS 6718) (check-in: e557c8e5 user: drh tags: trunk)
17:02
Fix an assertion fault in balance_quick() that occurs when an interior btree node has zero cells due to database corruption. Also update the corrupt7.test result vectors for a couple of cases where the error report on database corruption changed due to earlier detection. (CVS 6717) (check-in: 1335e444 user: drh tags: trunk)
16:14
If the root page of a btree is empty and is also not a leaf page and the page is not page 1, then report database corruption. (CVS 6716) (check-in: 52b02ca5 user: drh tags: trunk)
14:46
Reduce the stack usage of balance_quick(). (CVS 6715) (check-in: e7ad68e9 user: danielk1977 tags: trunk)
02:47
Minor updates to comments in test scripts. (CVS 6714) (check-in: 453ff88f user: shane tags: trunk)
02:46
Minor tweak to test script to ensure every byte in file touched at least once. (CVS 6713) (check-in: bc6c2d89 user: shane tags: trunk)
00:11
Fix two instances where a malformed header in a database file (in other words a corrupt database file) can lead to an assertion fault. (CVS 6712) (check-in: 4e92c7f2 user: drh tags: trunk)
2009-06-03
21:04
Change the pcache1.c implementation so that the "header" occurs at the end of page buffer, not at the beginning. This insures that the 20 bytes immediately following the page buffer are mapped if a read of the page buffer overruns due to a malformed cell. (CVS 6711) (check-in: c54de1f5 user: drh tags: trunk)
17:26
Add corruptD.test, a container for testing the "cell overflow" problem. Also shuffle a small amount of code in BtreeInitPage() to check that the page header pointer to the start of the cell offset array is set to a sane value. (CVS 6710) (check-in: 7fa5d3cb user: danielk1977 tags: trunk)
11:25
Define a set of constants to use as the "index" argument to sqlite3BtreeGetMeta and UpdateMeta. This makes some parts of the code easier to follow. (CVS 6709) (check-in: 6dbf4eca user: danielk1977 tags: trunk)
01:24
Additional changes to reduce stack usage. The SQLITE_SMALL_STACK compile-time option is now available. (CVS 6708) (check-in: baea79fd user: drh tags: trunk)
2009-06-02
21:31
Further reductions in the amount of stack space required. (CVS 6707) (check-in: 04bad9eb user: drh tags: trunk)

Tweaks to vdbe.c to further reduce stack space requirements. (CVS 6706) (check-in: 6f2aab3f user: drh tags: trunk)
15:47
Add a test case for ticket #3893 and ticket #3894. (CVS 6705) (check-in: 2472f6db user: drh tags: trunk)
15:21
Add the vdbe-compress.tcl script which automatically refactors the sqlite3VdbeExec() routine to use less stack space. Use this script when constructing the amalgamation. (CVS 6704) (check-in: 7f433918 user: drh tags: trunk)
2009-06-01
19:53
Avoid allocating large objects on the stack in the incremental BLOB I/O interface. (CVS 6703) (check-in: ea7dfde7 user: drh tags: trunk)
18:18
Malloc for space to hold the Parse object in sqlite3_prepare() and friends. Or, if compiled with SQLITE_USE_ALLOCA, obtain space for the object from alloca(). (CVS 6702) (check-in: c7c0c58e user: drh tags: trunk)
17:10
Added assert to verify winMutex system is inited before "static" mutexes are used. (CVS 6701) (check-in: b126013b user: shane tags: trunk)
17:06
Ensure that "static" mutexes are deleted on shutdown so that they are not leaked across restarts. (CVS 6700) (check-in: 4e75897e user: shane tags: trunk)
16:53
Fix compiler warnings with MSVC build. (CVS 6699) (check-in: 07915885 user: shane tags: trunk)

Code simplifications to facilitate coverage testing following the recent changes to the Expr object. (CVS 6697) (check-in: ee9a144d user: drh tags: trunk)
17:16
Fix the ".genfkey" command of the CLI so that it does not leak memory if sqlite3_realloc() fails. Ticket #3891. (CVS 6696) (check-in: a028d69c user: drh tags: trunk)
2009-05-30
23:35
Fix typo reported by ticket #3888. Other minor edits to facilitate coverage testing. (CVS 6695) (check-in: 164adf26 user: drh tags: trunk)

Fix for ticket #3887. Other unrelated bits of code cleanup in the expr.c source module. (CVS 6693) (check-in: 00e7250f user: drh tags: trunk)
10:46
In vacuum.c use "PagerIsMemdb(X)" instead of "PagerFile(X)->pMethods==0". (CVS 6692) (check-in: 874295ce user: danielk1977 tags: trunk)
2009-05-29
19:00
Enhance the sqlite3VdbeGetOp() routine so that it always returns a pointer to VdbeOp, even following an OOM fault. This simplifies error handling in callers. Cleanup to the column cache logic and the expr.c source module. (CVS 6691) (check-in: ede06dac user: drh tags: trunk)
14:39
Refinements in expression handling logic that have resulted from recent structural testing. (CVS 6690) (check-in: bd89f2c2 user: drh tags: trunk)
11:57
Still more refinements to the hasHotJournal() fix of ticket #3883. (CVS 6689) (check-in: 726b425e user: drh tags: trunk)
10:55
The hasHotJournal() fix of check-in (6687) causes some minor problems in various alternative operating modes, such as locking_mode=EXCLUSIVE. This additional patch attempts to fix those concerns. Ticket #3883. (CVS 6688) (check-in: a2ba61d9 user: drh tags: trunk)
00:30
Modify the hasHotJournal() routine to return a false-positive if it is unable to open the journal file to check its header due to a race condition. Processing downstream of hasHotJournal() already knows how to deal with false-positives. Ticket #3883. (CVS 6687) (check-in: d6b5d8e1 user: drh tags: trunk)
2009-05-28
21:04

12:49
Make sure the column name resolver does not try to duplicate Expr.u.zToken when the Expr.u.iValue union member is the element being used. (CVS 6684) (check-in: 376ecf0d user: drh tags: trunk)
11:05
Workaround the need for internal API sqlite3BtreeCursorDb(). It was only being used for an assert() statement, which can be done differently. (CVS 6683) (check-in: 5904af6e user: danielk1977 tags: trunk)
01:00
Additional refinements to Expr handling. Restore compression of trigger expressions. Change Expr.zToken to Expr.u.zToken and added Expr.u.iValue. Remove an unnecessary ExprDup from CHECK constraint processing. And so forth. (CVS 6682) (check-in: 4ac2bdfb user: drh tags: trunk)
2009-05-27
10:31
Simplifications to the Expr object: Remove Expr.span completely and convert Expr.token into a char* Expr.zToken. Also simplify the Token object by removing the Token.dyn and Token.quoted fields. (CVS 6681) (check-in: 7cb1c3ba user: drh tags: trunk)
2009-05-25
14:17
Fix the rtree test module so that it works even if the ext/ subfolder is omitted from the tree. (CVS 6679) (check-in: 086206e1 user: drh tags: trunk)
11:46
When pinning a temp register after it is reused by the column cache, make sure all instances of that register in the cache are pinned so that the register is never reused for a different purpose. Ticket #3879. (CVS 6676) (check-in: 5f358e63 user: drh tags: trunk)
11:46
Add a test case for ticket #3879. (CVS 6675) (check-in: 5b9b66f4 user: danielk1977 tags: trunk)
2009-05-24
21:59
Additional clarification of the 3rd parameter to sqlite3_create_function(). Documentation change only; no changes to code. Ticket #3875. (CVS 6674) (check-in: dd75e376 user: drh tags: trunk)
11:08
In the previous, the upper bound on the number of function arguments is 127, not 255. Ticket #3876 (CVS 6673) (check-in: 4fe4c5fa user: drh tags: trunk)
11:07
Correct and clarify the documentation on the third parameter to sqlite3_create_function(). (CVS 6672) (check-in: 6b7929ed user: drh tags: trunk)
2009-05-22

Do not transform a WHERE clause of the form "a = ? OR a = ?" to "a IN (?, ?)" if "a" is a column of a virtual table. Ticket #3871. (CVS 6671) (check-in: fad88e71 user: danielk1977 tags: trunk)
11:12

Rework the logic that generates a schema for tables created using "CREATE TABLE ... AS SELECT ...". Instead of trying to copy the raw datatype string from the right-hand side, just make the type one of TEXT, INT, REAL, NUM, or nothing. This is much simpler than trying to parse and quote datatype strings. Other minor implifications to build.c are bundled with this change. (CVS 6626) (check-in: 33cf8359 user: drh tags: trunk)
