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).

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

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

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

run autoconf so the updated version is in the configure script (CVS 6301) check-in: edbb3586 user: vapier tags: trunk
04:34
break libsqlite3.la install step out so the tcl install step can depend on it as well (CVS 6300) check-in: 0998c554 user: vapier tags: trunk
00:00
Version 3.6.11 (CVS 6299) check-in: 6abd630c user: drh tags: trunk, release
2009-02-17
18:37
Add tests to double-check that nothing within SQLite ever tries to allocate amounts of memory that are close to the maximum signed integer, leading to an integer overflow within malloc(). This is not currently a problem. The extra tests just insure it never becomes a problem. (CVS 6298) check-in: f6ba7bb9 user: drh tags: trunk
17:56
Initialize an uninitialized buffer to silence a valgrind warning during a VACUUM operation. (CVS 6297) check-in: 8c61968b user: danielk1977 tags: trunk
16:29
Allow sqlite3_shutdown() to be called by a process before sqlite3_initialize() is. Prior to this commit such a call could segfault. (CVS 6296) check-in: 79431c58 user: danielk1977 tags: trunk
16:17
Make sure result variables are initialized or unused following a failure of the xFullPathname VFS interface. Problem detected by valgrind. (CVS 6295) check-in: 59a47551 user: drh tags: trunk

17:01
Fix some edge cases with backing up databases that are exactly PENDING_BYTE bytes in size, or just slightly larger. (CVS 6288) check-in: 2fc450e8 user: danielk1977 tags: trunk
09:36
Modify lock.test to account for "PRAGMA lock_status" returning "unknown" for in-memory databases. (CVS 6287) check-in: 9a6e558b user: danielk1977 tags: trunk
09:11
Fix a case where during a rollback triggered by an IO or malloc error an unjournalled region of the database could be written to (with it's original data). This was causing an assert in test_journal.c to fail. Add a test case in ioerr2.test to trigger this case. (CVS 6286) check-in: 315a6692 user: danielk1977 tags: trunk
2009-02-11
16:06
Updated for Windows compatibility. Test scripts only. (CVS 6285) check-in: 2522ad1d user: shane tags: trunk

07:38
Modify the test_journal.c code to (1) account for the backup code writing to parts of the pending-byte page when changing a databases page-size, and (2) to avoid reading from the pending-byte page and triggering the assert in os_unix.c. Changes to test code only. (CVS 6280) check-in: 48796216 user: danielk1977 tags: trunk
05:18
In test_mutex.c, zero the global structure staticly instead of in Sqlitetest_mutex_Init(). This is because Sqlitetest_mutex_Init() is now called by each thread during thread tests ((6193)). Test code changes only. (CVS 6279) check-in: 8b318b93 user: danielk1977 tags: trunk
2009-02-10
18:54
For the "onefile" demo, pass SQLITE_OPEN_TEMP_DB instead of MAIN_DB to the OS layer when opening the single file. This is to work around the assert() in os_unix.c that tests that the locking region is not written to. (CVS 6278) check-in: 2da076a2 user: danielk1977 tags: trunk
14:45
Reduce the number of iterations in one of the savepoint4.test crash tests. (CVS 6277) check-in: fafb07b8 user: danielk1977 tags: trunk
14:28

13:41
Create links from backup API documentation to the backup application note. Comment changes only - no changes to code. (CVS 6275) check-in: 85de23fb user: drh tags: trunk
11:17
Reenable triggering vdbe tracing by creating file-system entries. Add a (redundant) test that modifying the temp schema expires all prepared statements. (CVS 6274) check-in: f6590dac user: danielk1977 tags: trunk
10:44
Do not always open a transaction on the temp database when writing to the main or another attached database. (CVS 6273) check-in: f76b0b81 user: danielk1977 tags: trunk
05:45
Fix a bug in test file misc7.test. No code changes. (CVS 6272) check-in: d919d2a1 user: danielk1977 tags: trunk
2009-02-09
18:55
Fix a problem in backup.c causing OsTruncate() to be called with an argument larger than the current file-size. (CVS 6271) check-in: b34bde80 user: danielk1977 tags: trunk
17:34
Add assert() statements to os_unix.c which fire if there is a read or write for the locking region of a database file. (CVS 6270) check-in: 93e792ff user: drh tags: trunk
13:19
Better error message when DISTINCT is used on an aggregate function that takes two or more arguments. Ticket #3641. (CVS 6269) check-in: e20bf384 user: drh tags: trunk

Attempt to reproduce ticket #3643. No luck yet. (CVS 6267) check-in: 8f2f98d2 user: danielk1977 tags: trunk
2009-02-06
05:59
Changes to the backup API: (1) if a negative number is passed as the second argument to backup_step(), this is interpreted as "copy all remaining pages" and (2) if backup_finish() is called after backup_step() fails with a BUSY or LOCKED error, then this error is also returned by backup_finish() (same handling as for other errors encountered by backup_step()). (CVS 6266) check-in: 9b8c8b18 user: danielk1977 tags: trunk
2009-02-05
17:00
Fix a test case that was still using the old pending_byte mechanism. (CVS 6265) check-in: 08ec4f2c user: drh tags: trunk

03:00
Improved overrun detection in mem2.c (SQLITE_MEMDEBUG). Previously was only checking up to 3 extra bytes allocated due to rounding. (CVS 6261) check-in: a6fe3d6b user: shane tags: trunk
2009-02-04
22:46
Add "backup" and "restore" methods to the TCL interfaces and test cases to exercise those methods. (CVS 6260) check-in: e420a3ce user: drh tags: trunk
20:55
Add ".backup" and ".restore" commands to the CLI - implemented using the new backup API. (CVS 6259) check-in: 003e1d62 user: drh tags: trunk
20:08
Increase the version number to 3.6.11. (CVS 6258) check-in: 0882a028 user: drh tags: trunk
19:16
If the truncate operation fails in journalmode=TRUNCATE, do not fall back to overwriting the journal header with zeros. Simply fail the operation. (CVS 6257) check-in: d4af60e5 user: drh tags: trunk
17:40
Simplify wording of backup API error message. Decapitalize some other error messages. (CVS 6256) check-in: f92405af user: drh tags: trunk
16:56
The sqlite3_backup_init() interface must lock the destination in case it needs to change the error message. (CVS 6255) check-in: 572378d3 user: drh tags: trunk
15:27
Fix a bug in test_malloc.c whereby running multi-threaded test cases could cause subsequent OOM tests to fail. (CVS 6254) check-in: 03ea9e59 user: danielk1977 tags: trunk
11:57
Ensure that thread001.test and thread002.test reset the global shared-cache-enabled setting before they finish. (CVS 6253) check-in: 416288a9 user: danielk1977 tags: trunk
10:09

08:17
Fix a bug in malloc.test causing the exclusive permutation to fail. Changes to test code only. (CVS 6251) check-in: 72745bde user: danielk1977 tags: trunk
03:59
Changes to completely remove all floating point ops if SQLITE_OMIT_FLOATING_POINT defined. Note that w/o fp, date/time, round, nan, etc. are all gone or limited in functionality. Updated some of the test scripts to support missing fp and 64-bit functionality. Ticket #3029. (CVS 6250) check-in: 5cef4000 user: shane tags: trunk
01:49
