23:23
In the unix-backend, when simulating an I/O error on an unlock operation, still mark the connection as unlocked to avoid a future assert(). (CVS 6401) (check-in: fb35cff8 user: drh tags: trunk)
18:56
The test_async.c module must pass an unchanging filename to the underlying VFS. (CVS 6400) (check-in: d1eeee21 user: drh tags: trunk)

15:04
Back out check-in (6380). Replace it with a proper fix to the xFullPathname method in the async VFS. (CVS 6398) (check-in: 767a7f7b user: drh tags: trunk)
10:54
The fix in (6395) was not correct. Fix #3756 a different way. (CVS 6397) (check-in: 9278f7b1 user: danielk1977 tags: trunk)
07:03
Fix a couple of test script bugs. No changes to SQLite code. (CVS 6396) (check-in: c9fa329f user: danielk1977 tags: trunk)
06:59
Fix readDbPage() so that if an SQLITE_IOERR_SHORT_READ is encountered, the page content is zeroed. Ticket #3756. (CVS 6395) (check-in: 647e3b15 user: danielk1977 tags: trunk)
2009-03-27
15:26

14:48
Prevent the tcl test suite from throwing an exception when a threadsafe SQLite is linked against a non-threadsafe Tcl for testing. Print a warning instead. Ticket #3753. (CVS 6389) (check-in: a22e7c81 user: danielk1977 tags: trunk)
12:20
Added new tests of the scratch memory allocator for increased test coverage. (CVS 6388) (check-in: e99e28ef user: drh tags: trunk)
11:49
Ensure that the test vfs in test_journal.c zeroes sqlite3_file.pMethods if an xOpen() call fails. Similar problem to that fixed by #6384. This was a problem with test code, not SQLite itself. (CVS 6387) (check-in: 45ae830d user: danielk1977 tags: trunk)
2009-03-25
16:51

Fix a problem preventing sqlite3_extended_errcode() from working correctly. (CVS 6385) (check-in: de469c46 user: danielk1977 tags: trunk)
14:24
When a VFS.xOpen fails, make sure the pMethods pointer is zeroed on the sqlite3_file object so that subsequent xClose() operations against that same file handler are no-ops. Bug in the test_async.c module only - not in the core library. Ticket #3744. (CVS 6384) (check-in: c32b4541 user: drh tags: trunk)
01:06
Use fdatasync() only on linux, unless -Dfdatasync=fdatasync is set at compilation time. (CVS 6383) (check-in: cbf2ca4c user: drh tags: trunk)
2009-03-24
18:42
Change OS_UNIX to SQLITE_OS_UNIX in test_thread.c. Modify notify2.test to print out its timings in addition to reporting success or failure. (CVS 6382) (check-in: 940d72d2 user: drh tags: trunk)

16:55
Adjust the lock.test and lock3.test scripts so that they work with the asynchronous VFS. (CVS 6380) (check-in: 40df926b user: drh tags: trunk)
16:27
Include sqliteInt.h in test_async.c so that the asynchronous VFS tests will run even if SQLITE_OS_UNIX is not explicitly defined. (CVS 6379) (check-in: 29b0d6a3 user: drh tags: trunk)
15:31
New assert()s added to verify that the Expr.token value is used correctly. Ticket #3743. (CVS 6378) (check-in: cf3d84ab user: drh tags: trunk)
15:08
Changes to insure that lookaside memory allocations are never used to hold schema content. Ticket #3743. (CVS 6377) (check-in: ea74d8dc user: drh tags: trunk)
04:46
Add a comment to prepare.c explaining why the lookaside buffer is disabled before sqlite3_exec() is called to parse a schema statement. No code changes. (CVS 6376) (check-in: 8ca6a665 user: danielk1977 tags: trunk)
2009-03-23
21:37
Clarify the meaning of a comment. No changes to code. (CVS 6375) (check-in: 7c2df04b user: drh tags: trunk)
17:49
Add asserts to make sure that database connection locks are held when accessing the lookaside memory allocation buffers. No defects were found. (CVS 6374) (check-in: 8a9f3e66 user: drh tags: trunk)
17:11
Fix an obscure race condition that can occur when multiple threads, shared cache and DDL statements are combined. Enhance notify2.test to test this scenario. (CVS 6373) (check-in: 92ec5975 user: danielk1977 tags: trunk)
04:33
Use the ROUND8() macro to round an integer up to the nearest multiple of 8 and ROUNDDOWN8() macro to round down to the nearest multiple of 8. This is a cosmetic change. (CVS 6372) (check-in: db1d4d2f user: danielk1977 tags: trunk)
02:34
Fix compiler warning in MSVC. (CVS 6371) (check-in: 83a4d5b3 user: shane tags: trunk)
2009-03-22
20:36

2009-03-21
16:19
Update comments in build.c to conform to the latest implementation. (CVS 6369) (check-in: a915e8e0 user: drh tags: trunk)
14:56
Rig the unix backend to use fdatasync() by default, without having to set the HAVE_FDATASYNC macro. Systems that do not support fdatasync() can be compiled using -Dfdatasync=fsync. (CVS 6368) (check-in: a3315627 user: drh tags: trunk)
14:41
On unix, always use fdatasync() instead of fsync() when available, even if the file size changes, since (we are told) fdatasync() will automatically flush the inode when the file size changes. (CVS 6367) (check-in: 0d6b11bc user: drh tags: trunk)
2009-03-20
15:16

13:15
Rename the unused MEM2 static mutex to OPEN and reuse it to serialize access to the sqlite3BtreeOpen() routine to prevent a race condition on detection of sharable caches. Ticket #3735. (CVS 6363) (check-in: 19fa5a29 user: drh tags: trunk)
10:24

2009-03-19
18:51
Fix a couple of fairly obscure cases where an assert() could fail following a malloc failure. (CVS 6360) (check-in: cc0d9256 user: danielk1977 tags: trunk)
07:58
Change sqlite3_step() to return SQLITE_LOCKED if a statement cannot be re-compiled due to locks on the shared-cache schema. Also add a blocking wrapper of sqlite3_prepare_v2() to the test code. (CVS 6359) (check-in: e8be1af9 user: danielk1977 tags: trunk)
2009-03-18
18:43
Fix a crash that could occur when creating an index in shared-cache mode with lookaside enabled. (CVS 6358) (check-in: 097737e3 user: danielk1977 tags: trunk)

2009-03-17
22:33
Move the rowid cache out of VdbeCursor and into BtCursor. When multiple BtCursors are open on the same table, set their rowid cache all at the same time. Ticket #3731. (CVS 6354) (check-in: 18978583 user: drh tags: trunk)
17:49

14:48
Modify quick.test to support the QUICKTEST_INCLUDE environment variable, which can be used to override the built-in EXCLUDE list. (CVS 6350) (check-in: fdfe22f0 user: danielk1977 tags: trunk)
13:37
Additional hyperlinks in the sqlite3_unlock_notify() documentation. (CVS 6349) (check-in: 4dae5f6e user: drh tags: trunk)

2009-03-14
08:37
Fix for #3719. When synthesizing a CREATE TABLE statement as as result of a "CREATE TABLE AS", quote the column type names unless they are simple identifiers or simple identifiers followed by one or two dimensions (e.g. "VARCHAR(10)"). (CVS 6345) (check-in: 7c6437ef user: danielk1977 tags: trunk)

Make calls to sqlite3BtreeRollbackStmt() no-ops when passed a Btree* handle that does not have an open statement transaction. Ticket #3718. (CVS 6342) (check-in: a1bb1aef user: danielk1977 tags: trunk)
2009-03-05
14:59
Begin purging dirty pages from the cache once 90% of the cache is dirty (insteadof waiting until it is 100% dirty). This improves performance in some circumstances by effectively reserving 10% of the configured page-cache for frequently reused read-only pages. (CVS 6341) (check-in: 823fe7f5 user: danielk1977 tags: trunk)
14:53

2009-02-28
10:47
Instead of linking temporary triggers on non-temporary tables into the Table.pTrigger list, search the temp schema for them on demand. Fix for #3688. (CVS 6329) (check-in: 3befe1ef user: danielk1977 tags: trunk)
2009-02-26
07:15
In sqlite3_table_column_metadata(), hold the mutex on all attached BtShared objects while accessing schema objects. Fix for #3679. (CVS 6328) (check-in: d197afd6 user: danielk1977 tags: trunk)
2009-02-25
19:07

2009-02-23
17:33
Scan an index instead of a table for "SELECT count(*) FROM <tbl>" queries. Because an index is usually smaller than a table on disk, this saves some IO. (CVS 6315) (check-in: 294ba6f7 user: danielk1977 tags: trunk)
16:52
Add the reverse_unordered_selects pragma. (CVS 6314) (check-in: bc078e00 user: drh tags: trunk)

2009-02-21
22:38
The sqlite3.def file is automatically generated and is not suppose to be part of the source code repository. So it is hereby removed. Ticket #3671. (CVS 6312) (check-in: 5dcda154 user: drh tags: trunk)
2009-02-20
22:27
unbreak Autoconf-based build procedure by added missing backup.lo to the list of library objects (CVS 6311) (check-in: 94945801 user: rse tags: trunk)
10:58

03:02
Add the OP_HaltIfNull opcode and use it to simplify prepared statements for INSERTs and UPDATEs of tables with NOT NULL columns. (CVS 6308) (check-in: feccad8d user: drh tags: trunk)
01:28
Reuse space left-over opcode space at the end of the VDBE opcode array to store memory cells, VDBE cursors, and other content needed by the VDBE. This reduces the memory required by a prepared statement. (CVS 6307) (check-in: 58a18092 user: drh tags: trunk)
2009-02-19
20:50
Remove code in malloc.c that was already commented out using #if 0. (CVS 6306) (check-in: e1ad757e user: drh tags: trunk)
14:39
Changes to reduce the heap space consumed by triggers, views and tables in the in-memory representation of the schema. Also to reduce the space used by prepared statements slightly. (CVS 6305) (check-in: d9f6ffbc user: danielk1977 tags: trunk)
2009-02-18
20:31
Make sure the auto_vacuum=INCREMENTAL setting is preserved across a VACUUM. Ticket #3663. (CVS 6304) (check-in: ded04f12 user: drh tags: trunk)
18:37
Move the text of C-API requirements out of the sqlite.h.in source file and into separate files in the "docsrc" CM system. Comment changes only - no changes to code. (CVS 6303) (check-in: 419eb48b user: drh tags: trunk)
