100 check-ins occurring around 6301f08a2b32289a.

2009-02-18
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
2009-02-16
17:55
Changes to remove some compiler warnings from MSVC. (CVS 6294) check-in: 68f15442 user: shane tags: trunk
16:23
Fix a compiler warning in backup.c. (CVS 6293) check-in: 82222fbf user: drh tags: trunk
2009-02-13
16:59
Make sure OOM errors in the ANALYSIS loader get reported back out to high-level layers. Strange behavior can result otherwise. (CVS 6292) check-in: 88a6355c user: drh tags: trunk
03:43
Correctly handle attempts to add a UNIQUE or PRIMARY KEY column using the ALTER TABLE statement. Ticket #3651. (CVS 6291) check-in: dd179ff2 user: drh tags: trunk
2009-02-12
17:07
Add additional cross-references from API documentation to other documents. Comment changes only; no changes to code. (CVS 6290) check-in: 97203a0a user: drh tags: trunk
17:06
Update thread tests to clear the sqlite_open_file_count counter at the end. This counter is not threadsafe and can end up with an invalid value at the end of the thread tests. (CVS 6289) check-in: 8c4d71a1 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
15:23
Continuing documentation refinements. Comment changes only. (CVS 6284) check-in: 83e83084 user: drh tags: trunk
15:11
Fix the backup.test script so that it works regardless of the value of SQLITE_TEMP_STORE and the initial contents of the file-system. (CVS 6283) check-in: da660ea7 user: danielk1977 tags: trunk
15:04
Add hyperlinks from sqlite3_limit() documention to the limits.html page. Comment changes only - no changes to code. (CVS 6282) check-in: f0189ec8 user: drh tags: trunk
14:27
Fix the crashtest infrastructure so that it doesn't trigger the "don't write to the locking region" assert in os_unix.c. (CVS 6281) check-in: b7fd4615 user: danielk1977 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
Prevent code in test6.c from reading the 512 byte locking region (the PENDING_BYTE page) of a database file. Doing so triggers an assert failure in os_unix.c. (CVS 6276) check-in: 2a6a4316 user: danielk1977 tags: trunk
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
05:32
Ignore the return structure of and F_GETLK fcntl() call on djgpp. Fix for #3642. (CVS 6268) check-in: 8227af34 user: danielk1977 tags: trunk
05:18
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
16:53
Fix the declaration of sqlite3PendingByte so that it works with the amalgamation. (CVS 6264) check-in: 193c871f user: drh tags: trunk
16:31
Make the pending byte adjustable via sqlite3_test_control() on all builds, not just on test builds. (CVS 6263) check-in: e8f192e2 user: drh tags: trunk
03:16
Fixed error detection in winTrucate() in os_win.c. Windows version only. Ticket #3640. (CVS 6262) check-in: 82e03f1b user: shane 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
Do not attempt to use the sub-journal file descriptor if it is not opened (as in journal_mode=off mode). Ticket #3636. (CVS 6252) check-in: 20bd7605 user: danielk1977 tags: trunk
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
Remove compiler warnings under MSVC. (CVS 6249) check-in: 6301f08a user: shane tags: trunk
2009-02-03
22:51
Correction to check-ins (6246) and (6247): The backup object might not hold a valid destination connection pointer. Also, do not reset the page cache when establishing a read-lock while there is a persistent or truncated journal, only if there is a journal that really needs to rollback. Otherwise backups always reset whenever the source database file is read. (CVS 6248) check-in: 7f827ba9 user: drh tags: trunk
22:17
A backup must clear the internal schema of the destination database so that the schema will be reloaded for the next sqlite3_prepare() (CVS 6247) check-in: 76f23a43 user: drh tags: trunk
21:13
Must hold mutex on the destination during backups. Add documentation to warn programmers that attempting to use the destination connection during a backup can lead to deadlock. (CVS 6246) check-in: 5f6c06b9 user: drh tags: trunk
19:55
Fixed postToParent() return type (Tcl_ThreadCreateType) in test_thread.c to compile with MSVC. Removed a few compiler warnings. Test harness change only. (CVS 6245) check-in: e9475aba user: shane tags: trunk

15:27
Check at the write() call to work around the msdos bug in OSX actually succeeds and throw an error if it does not. #ifdef out the work-around for all platforms other than OSX. Ticket #3633. (CVS 6237) check-in: b054b569 user: drh tags: trunk
13:51

13:10
Check-in (6230) introduced a bugs in SUBSTR() which was caught by the fuzz tester. Fixed by this check-in. Related to ticket #3628. (CVS 6234) check-in: cd2e7f6c user: drh tags: trunk
2009-02-02
21:57
Make group_concat() a 1- or 2-value function, as the documentation says it should be. Use the md5sum() function to verify ticket #3179, not group_concat(). This undoes the ill-advised group_concat() change of check-in (5233). (CVS 6233) check-in: f2ae82c4 user: drh tags: trunk
18:03

2009-01-29
19:27
Add test cases to make sure that keywords that we say can be used as identifiers really can be used as identifiers. These tests were inspired by ticket #3612, but they do not directly address ticket #3612. (CVS 6214) check-in: 6041ca87 user: drh tags: trunk
02:54
add a cvsignore file (CVS 6213) check-in: 68c8cdd7 user: vapier tags: trunk
