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

2010-06-17
17:05

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

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

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

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

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

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

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

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

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

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

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

Add tests to fkey2.test to check that ON CONFLICT clauses do not affect SQLite's behaviour when an FK constraint is violated. check-in: e9e5b100 user: dan tags: trunk
06:18
Minor changes to checksum related test cases. check-in: 60c22bde user: dan tags: trunk

2010-05-26
17:31
Make sure the wal-index mapping is always large enough to cover the entire active area of the wal-index. check-in: 42705bab user: drh tags: trunk
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

10:50
If a writer exits unexpectedly in the middle of a transaction, have the following writer remove any wal-index hash-table entries left by the interrupted transaction. check-in: ed77556a user: dan tags: trunk
02:24
Remove unreachable code associated with WAL from the pager. check-in: 54c1718e user: drh tags: trunk
2010-05-24

17:00
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
12:34
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
00:55
Add several EXPENSIVE_ASSERT code blocks to validate the wal-index hash table. Fix the bugs that these code blocks fine. Rename walClearHash() to walCleanupHash() and simplify its interface. check-in: 7aade899 user: drh tags: trunk
2010-05-21
19:15
Fix another bug in walClearHash(). check-in: 40f80ffe user: dan tags: trunk
18:24
Comment out the SQLITE_FCNTL_SIZE_HINT from os_unix.c since it does not seem to provide any performance gain there. check-in: 7d01309d user: drh tags: trunk
16:23
Correct an off-by-one bug in the previous commit. check-in: 75a1130d user: dan tags: trunk

Remove entries from wal-index hash tables when a rollback or savepoint rollback occurs. check-in: 36795c2b user: dan tags: trunk
13:16
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
22:09

19:39
Add the SQLITE_FCNTL_SIZE_HINT to the os_win.c VFS. check-in: 9894118d user: drh tags: trunk
19:26
Add the SQLITE_FCNTL_SIZE_HINT operator to sqlite3_file_control() and use it to give the VFS hints about the ultimate size of a database file when the file is growing. check-in: 2b7e3b4a user: drh tags: trunk
19:09
Fix a bug in the new checkpoint computation. Also update the checkpoint algorithm in the test scripts to align with the new implementation. check-in: 8b6056f2 user: drh tags: trunk

2010-05-18
23:29
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
13:27

2010-05-15
10:24
Add a note to the documentation of sqlite3_wal_hook() to say not to return SQLITE_ROW or SQLITE_DONE. Or any other value that is not a valid SQLite error code. check-in: 2f0b6cbf user: dan tags: trunk
01:09
Silently ignore errors trying to set the default journal_mode while doing an ATTACH. check-in: b9af4ad2 user: drh tags: trunk
2010-05-14
20:15
Fix a typo that (by bad luck) was not a syntax error but which caused some important lines of code to be skipped when SQLITE_DEBUG was not used. check-in: 9ef99d97 user: drh tags: trunk
19:24
Make sure the value of an INTEGER PRIMARY KEY column supplied to triggers and especially to FK constraints really contains the ROWID and not the NULL that is stored in the column itself. Ticket [dd08e5a988d00dec]. check-in: 636f8609 user: drh tags: trunk
16:34
Pull in all the latest changes from the trunk. Update the win32 SHM methods to work with the new interface design. Closed-Leaf check-in: 4b69f2cd user: drh tags: wal-win32
14:52
Simplifications to the SHM implementation in os_unix.c, taking advantage of the removal of the LinuxThreads mess. check-in: d1debe5d user: drh tags: trunk
12:43
Simplify os_unix.c by removing support for LinuxThreads. Linux systems must either use NPTL or else not share database connections across threads. check-in: e294b696 user: drh tags: trunk
11:30
Change the OSTRACEn() macro to OSTRACE(()). Also rename some internal fields and variables in os_unix.c to be more meaningful and searchable. check-in: 5fe529f2 user: drh tags: trunk
10:43
Fix test_osinst.c so that it does not depend on gettimeofday() unless SQLITE_OS_UNIX is defined and NO_GETTOD is not defined. check-in: 2a4014b7 user: dan tags: trunk
