37 check-ins using file src/vdbeapi.c version afd3837c

2006-01-16
02:39
Version 3.3.1 (alpha) (CVS 2953) check-in: bd7c5699 user: drh tags: trunk
02:37
Fix the script that cross-compiles the windows DLL so that it works correctly with the latest interface. Ticket #1614. Do not strip the windows DLL. Ticket #1474. (CVS 2954) check-in: 6591d365 user: drh tags: trunk
00:05
Version 3.3.1 (withdrawn - see ticket #1614) (CVS 2955) check-in: ed0f1d90 user: drh tags: trunk
2006-01-15
20:28
Code size reductions in the pager. (CVS 2952) check-in: c7da3aa9 user: drh tags: trunk
18:29
Prepare for the 3.3.1 alpha release. (CVS 2951) check-in: 3e32bcf0 user: drh tags: trunk
17:27
Clean up comments in os_unix.c. (CVS 2950) check-in: 2170e803 user: drh tags: trunk
14:11
Correctly set the length of the string in bytes when transforming an OP_String8 to OP_String in a utf-16 vdbe program. (CVS 2949) check-in: 69f996e0 user: danielk1977 tags: trunk
13:13
Fix a buffer-overrun that could occur after a malloc() failure. (CVS 2948) check-in: 66252221 user: danielk1977 tags: trunk
11:39
Rollback any open write-transaction when a shared-cache connection is closed. (CVS 2947) check-in: 1944d92b user: danielk1977 tags: trunk
02:43
Closing a file from the wrong thread is harmless on most systems. (See ticket #1611) But on systems like RedHat9 with broken fcntl() locks, it leaks file descriptors. That is better than the alternative of prematurely breaking locks and causing database corruption. Nevertheless, it would be good if we could figure out a way to report errors when closing a file from the wrong thread. (CVS 2946) check-in: ad8f12ca user: drh tags: trunk
02:30
Add tests and fix bugs in the new cross-thread lock resolution code. When an unlock fails, do not leak file descriptors (ticket #1611). But we really ought to report SQLITE_MISUSE or some other error instead of just returning SQLITE_OK. (CVS 2945) check-in: f68e05cb user: drh tags: trunk
00:13
Documentation updates. Fix to date.c. But most importantly: database connections are now allowed to change threads as long as they are not holding a lock. (CVS 2944) check-in: 03c422ec user: drh tags: trunk
2006-01-14
08:02
Fixes for OMIT_SUBQUERY builds: Disable where clause OR->IN optimization. Include EXISTS keyword (for new CREATE TABLE syntax). Test file fixes. (CVS 2943) check-in: 8e79a0c2 user: danielk1977 tags: trunk
2006-01-13
18:06
Account for multi-byte characters in ALTER TABLE code. Fix for #1609. (CVS 2942) check-in: d634f8b2 user: danielk1977 tags: trunk
17:12
Tweaks to make OP_Column run a fraction faster. (CVS 2941) check-in: 2d74cc22 user: danielk1977 tags: trunk
15:58
Avoid parsing an entire record header when it is not required. (CVS 2940) check-in: 0de729d9 user: danielk1977 tags: trunk
13:55
Make sure the authenticator does not try to authenticate columns in subqueries. Ticket #1607. (CVS 2939) check-in: 55b7dfaf user: drh tags: trunk
13:01
Fix a vdbe stack overflow problem that could occur with a correlated sub-query. (CVS 2938) check-in: caa7da80 user: danielk1977 tags: trunk
11:22
Remove a few duplicate variable initializations in sqlite3BtreeCursor(). (CVS 2937) check-in: 5e46ec01 user: danielk1977 tags: trunk
06:33
Minor modification to restoreOrClearCursorPosition() to improve efficiency. Do not allocate the extra 8-bytes if memory-management is not enabled. (CVS 2936) check-in: dd705955 user: danielk1977 tags: trunk
04:31
Additional speed enhancements in btree.c. (CVS 2935) check-in: 48b550ce user: drh tags: trunk
02:35
Small performance improvement on sqlite3BtreeMoveto. (CVS 2934) check-in: c780152f user: drh tags: trunk
01:48
Add a high-speed version of sqlite3GetVarint32 to vdbe.c for a 3% performance gain. (CVS 2933) check-in: a64e8251 user: drh tags: trunk
01:25
Add tests to make sure "PRAGMA table_info" works using sqlite3_prepare16. Ticket #1606. (CVS 2932) check-in: ace8ba81 user: drh tags: trunk
01:17
Terminate the va_start in the getDigits function of date.c. (CVS 2931) check-in: 94eac140 user: drh tags: trunk
2006-01-12
22:17
Add support for the TOTAL() aggregate function - works like SUM() except that it returns 0 instead of NULL when presented with an empty list. (CVS 2930) check-in: a7f528ff user: drh tags: trunk
20:28
Performance boost in sqlite3VdbeRecordCompare. (CVS 2929) check-in: 14c42307 user: drh tags: trunk
19:42
Automatically cast BLOBs to strings prior to handing them over to functions like LIKE that want strings. Ticket #1605. (CVS 2928) check-in: 730ddb0b user: drh tags: trunk
17:20
Cache the encoding value inside VdbeExec. (CVS 2927) check-in: 6d2a816e user: drh tags: trunk
15:01
Additional performance improvements in sqlite3BtreeMoveto. (CVS 2926) check-in: 52b3be96 user: drh tags: trunk
14:30
BtreeMoveto optimization goes about 1.5% faster. (CVS 2925) check-in: 4e4a6504 user: drh tags: trunk
12:43
About a 2.5% speed improvement by reducing the number of sqlite3ThreadData calls in the parser. (CVS 2924) check-in: 0caa1994 user: drh tags: trunk
02:50
Mark the end of the return codes in the sqlite3.h.in template file. (CVS 2923) check-in: 19b848d9 user: drh tags: trunk
01:56
Add the legacy_file_format pragma. (CVS 2922) check-in: b2dbd1a5 user: drh tags: trunk
01:25
Improve performance by about 10% by avoiding excess calls to get the thread-specific data. (CVS 2921) check-in: a8c74feb user: drh tags: trunk
2006-01-11
23:40
Testing of the automatic TSD deallocation logic. The sqlite3_thread_cleanup() API is documented. This should close ticket #1601. (CVS 2920) check-in: fb518b0c user: drh tags: trunk
21:41
Automatically deallocate thread-specific data when it is no longer being used. Ticket #1601. Also implemented the suggestion of ticket #1603. Memory management is now off by default at compile-time. The sqlite3_enable_memory_management() API has been removed. (CVS 2919) check-in: 5d9c6aa9 user: drh tags: trunk
