21 check-ins using file src/expr.c version 3b1a24aa

Disable the OR-clause optimization if it does not result in an index being used that would not have been used otherwise. In other words, do not convert OR clauses into an IN statement if it does not help the optimizer. (CVS 2789) (check-in: 7e7cfce0 user: drh tags: trunk)
14:08
Make sure left joins still work even when the OR clause optimization fires. Ticket #1537. (CVS 2788) (check-in: cbbeb9de user: drh tags: trunk)
03:51
Remove some vestiges of the old OS_TEST driver. (CVS 2787) (check-in: 008f676f user: drh tags: trunk)
03:43
Add an OS method for making copies of file descriptors. This fixes the crash tests. (CVS 2786) (check-in: 57a674fc user: drh tags: trunk)
00:25
Modify the OS layer so that I/O routines are called through a virtual function table. The os_test.c module has been replaced by test6.c. The crash tests are busted now and need to be fixed. (CVS 2785) (check-in: 1f69aec2 user: drh tags: trunk)

10:55
Ensure a low system limit on the number of open files does not cause manydb.test to fail. (CVS 2784) (check-in: dba2cc0d user: danielk1977 tags: trunk)
10:38
Add the compilation option SQLITE_DISABLE_DIRSYNC (CVS 2783) (check-in: f9f5ecbb user: danielk1977 tags: trunk)
10:38
Add the compilation option SQLITE_DISABLE_DIRSYNC (CVS 2782) (check-in: f1298bb1 user: danielk1977 tags: trunk)
09:01
If SQLITE_DISABLE_LFS is defined, omit the bigfile tests. (CVS 2781) (check-in: f882a516 user: danielk1977 tags: trunk)
08:47
Check the return code of full_fsync() when used to sync a directory fd. (CVS 2780) (check-in: 84aae3b0 user: danielk1977 tags: trunk)
02:43
Preserve 64-bit last insert rowids across triggers. (CVS 2779) (check-in: 4dd7cfaa user: drh tags: trunk)
2005-11-24
23:14
The --enable-cross-thread-connect configuration option or the -DSQLITE_ALLOW_XTHREAD_CONNECT compile-time option permits database connections to be moved across threads. This will cause latch-ups and failures on some linux systems such as RedHat-9. Do not use these options if you want a portable build. (CVS 2778) (check-in: 84aa4d58 user: drh tags: trunk)
22:33
Make sure sqliteInt.h is included before any system includes. This is required for QNX. Ticket #1478. (CVS 2777) (check-in: ab764535 user: drh tags: trunk)
22:22
Reduce the number of distinct token symbols in the parser so that the parser can store tokens in a single byte and thus be smaller in size. (CVS 2776) (check-in: 2dfc9863 user: drh tags: trunk)
14:34
Comment changes. No changes to code. (CVS 2775) (check-in: 786e23b2 user: drh tags: trunk)
14:24
Fix a comment in btree.c. No code changes. (CVS 2774) (check-in: 0d8bd133 user: drh tags: trunk)
13:15
Fix incorrect type conversions when copying from a table into itself. Ticket #1536. (CVS 2773) (check-in: a2e55a38 user: drh tags: trunk)
2005-11-21
12:48
Less verbose output when EXPLAIN QUERY PLAN identifies use of the primary key. (CVS 2772) (check-in: 5045f099 user: drh tags: trunk)
12:46
The EXPLAIN QUERY PLAN now identifies when tables use the integer primary key. (CVS 2771) (check-in: 80721e2c user: drh tags: trunk)
2005-11-16
13:47
Fix a problem with the sorting of literals in a compound query. Ticket #1501. (CVS 2770) (check-in: b3882b43 user: drh tags: trunk)
12:53
Do not allow aggregate functions in a WHERE clause. Ticket #1514. (CVS 2769) (check-in: bb866ed8 user: drh tags: trunk)
