12 check-ins using file src/vdbeaux.c version 1d765d67

2006-01-15
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)
