27 check-ins using file src/select.c version 2c408ab9

2018-03-27
13:57
Provide the ability for the VFS to do a blocking wait on locks if compiled with SQLITE_ENABLE_SETLK_TIMEOUT. (check-in: e7dff982 user: drh tags: trunk)
2018-03-26
21:05
Do not inject OOM errors on SQLITE_FCNTL_LOCK_TIMEOUT calls as an OOM is not possible in that context. (Closed-Leaf check-in: 5474e560 user: drh tags: lowlevel-lock-timeout)
20:43
Avoid a race condition that might cause a busy_timeout to last longer than it should. (check-in: b8196056 user: drh tags: lowlevel-lock-timeout)
17:56
Fix a typo preventing test script avtrans.test from running in auto-vacuum mode. (check-in: c7473bdb user: dan tags: trunk)
17:40
Add infrastructure to support for using F_SETLKW with a timeout on system that support that functionality. Requires SQLITE_ENABLE_SETLK_TIMEOUT. (check-in: 2e54a743 user: drh tags: lowlevel-lock-timeout)
16:37
Refactor some internal object element names used by the busy handler, to simplify analysis. (check-in: 6c40c557 user: drh tags: trunk)
2018-03-24
23:16
Fix a couple issues in the 'session' module tests. (check-in: ccf734f7 user: mistachkin tags: trunk)
20:06
Fix harmless compiler warning seen with MSVC. (check-in: e9508ab1 user: mistachkin tags: trunk)
18:01
Add testcase() macros and improve comments in the LEFT JOIN strength reduction optimization. (check-in: 56134577 user: drh tags: trunk)
15:47
Yet another fault in the sqlite3ExprImpliesNotNull() routine, causing errors in the LEFT JOIN strength reduction optimization of check-in [dd568c27b1d76563]. (check-in: e88cf3d4 user: drh tags: trunk)
15:08
Fix a test script problem causing shell1.test to fail with -DSQLITE_OMIT_VIRTUAL_TABLE builds. (check-in: 2e06906e user: dan tags: trunk)
13:24
Bug fix in the LEFT JOIN strength reduction optimization of check-in [dd568c27b1d76563]. The sqlite3ExprImpliesNotNull() routine was mistakenly assuming that a CASE expression must always be NULL if contained any reference to a variable that was NULL. (check-in: cf171abe user: drh tags: trunk)
00:19
Prepend linkage macros to the sqlite3rebaser interfaces. (check-in: c64e8f37 user: drh tags: trunk)
2018-03-23
17:36
Fix typos in sqlite3session.h preventing documentation webpages from being generated. Also mark all new sessions functions (those related to rebasing) as experimental. (check-in: de974235 user: dan tags: trunk)
16:31
Fix minor problems with passing NULL pointers to memcmp() and memcpy() found by -fsanitize=undefined. (check-in: 0b06ce6d user: dan tags: trunk)
16:08
Fix the -readonly option on the CLI so that it actually works. (check-in: 0477fb3f user: drh tags: trunk)
14:56
Add some more tests for the IS TRUE / IS FALSE operators. (check-in: 9fe5bebe user: mistachkin tags: trunk)
14:50
Fix typo in a comment used for documentation. No changes to code. (check-in: 49974d3b user: drh tags: trunk)
14:24
Enhance .schema in shell to enable matching patterns with literal underscores. (check-in: 98e3f524 user: mistachkin tags: trunk)
13:18
Fix an error in the CLI in the previous ([0249d9aecf69948]) check-in. Only the pattern to sqlite3_strlike() need to be escaped. (check-in: 71d5f6e6 user: drh tags: trunk)
12:59
Fix the ANALYZE command so that it will process tables whose names begin with "sqlite" as long as they do not being with "sqlite_". (check-in: 0249d9ae user: drh tags: trunk)
00:31
Fix harmless compiler warnings seen with MSVC. (check-in: 2f2be1b1 user: mistachkin tags: trunk)
2018-03-22
20:35
Add APIs to the sessions module for "rebasing" changesets. (check-in: 509506c7 user: dan tags: trunk)
17:13
Fix an RBU problem causing errors when updating tables with default collation sequences that require quoting (e.g. COLLATE "ICU_root-u-kn-on"). (check-in: eb4f452e user: dan tags: trunk)
17:02
Fix a test script problem causing rbuvacuum.test to fail when run along with other tests. (check-in: 901cb3b6 user: dan tags: trunk)
12:00
Add the left join strength reduction optimization. Enhance the push-down optimization so that it works with many LEFT JOINs. (check-in: dd568c27 user: drh tags: trunk)
2018-03-21
01:59
Relax LEFT-JOIN restrictions on the push-down optimization. (Closed-Leaf check-in: b5d3dd8c user: drh tags: join-strength-reduction)
