66 check-ins using file src/btree.c version 01559397

2010-04-30
21:03
Avoid assertion faults in queries using indices with redundant columns. Ticket [3dbdcdb14e7f41]. (check-in: 946e06cd user: drh tags: trunk)
05:57
Zero the "immediate FK constraint counter" associated with a statement object when sqlite3_reset() is called. Fix for [c39ff61c43]. (check-in: f660be61 user: dan tags: trunk)
2010-04-26
19:17
Optimization: Convert an ORDER BY clause into a no-op if the query also contains a GROUP BY clause that will force the same output order. (check-in: ca9d86ba user: drh tags: trunk)
17:36
Change the default_cache_size pragma to always store a positive value. (check-in: 36fb2cae user: drh tags: trunk)
17:30
Identify the SQLite version meta-value entry in the db-header output of showdb. (check-in: 245d934b user: drh tags: trunk)
16:47
Further enhancements to the showdb utility: A page number followed by "b" causes a btree decoding to occur on the page. (check-in: 2ff824e5 user: drh tags: trunk)
15:44
Enhancements to the showdb.c utility program. Automatically detect the page size and adjust the display accordingly. Add the "dbheader" display option. (check-in: 23eb408b user: drh tags: trunk)
2010-04-25
20:58
Remove an unreachable branch from the function initialization logic. (check-in: 064d3ddd user: drh tags: trunk)
2010-04-24
14:02
When commands such as ALTER TABLE and VACUUM use SQL internally, make sure they use only the built-in functions and not application-defined overrides for those functions. (check-in: 0291ed97 user: drh tags: trunk)
2010-04-23
14:29
Merge of notify.c changes from experimental. Reset stored blocking connection when registered unlock_notify callback is cleared. (check-in: e79dac3c user: shaneh tags: trunk)
2010-04-19
18:03
Add the sqlite3_log_hook() interface for scheduling checkpoints. (check-in: 9bda6014 user: dan tags: wal)
2010-04-17
18:50
Add some comments regarding file-locks to log.c. (check-in: 9d51c3b7 user: dan tags: wal)
17:34
Do not sync any files in wal mode if "PRAGMA synchronous=off" is set. If files are synced, pass either SQLITE_SYNC_FULL or SQLITE_SYNC_NORMAL to the xSync() callback as configured by "PRAGMA fullfsync". (check-in: 0ae91b00 user: dan tags: wal)
16:10
It is possible for sqlite3.pUnlockConnection to be non-NULL when sqlite3.pBlockingConnection is NULL, as the notify1.test script demonstrates. (Closed-Leaf check-in: 95ff76ef user: drh tags: experimental)
15:45
Merge with trunk commit [3e646e3f4c]. (check-in: 43463970 user: dan tags: wal)
15:42
In synchronous=normal mode, do not sync the log after every transaction. In synchronous=full mode, sync the log and add any extra frames required to avoid blast-radius related problems after each transaction. (check-in: 9bc9b684 user: dan tags: wal)
12:53
Change sqlite3_step() so that it automatically calls sqlite3_reset() instead of returning SQLITE_MISUSE when invoked on a prepared statement that previously returned any value other than SQLITE_ROW. (check-in: 3e646e3f user: drh tags: trunk)
12:31
Enhancements to wal-mode locking scheme. (check-in: 8549c286 user: dan tags: wal)
2010-04-16
22:05
Changes for branch coverage of notify.c. Fixed quirk of unlock_notify() where it would still think it was blocked after a callback was cleared (even after the transaction on the blocking connection was closed). (check-in: c54e8dad user: shaneh tags: experimental)
13:59
Change the log file format to include a small (12 byte) header at the start of the file. (check-in: 9865d14d user: dan tags: wal)
11:30
Fix bug in log recovery (last frame in log was being ignored). Also remove an incorrect assert statement. (check-in: 67d2a89e user: dan tags: wal)
2010-04-15
23:24
Disable query flattening when the outer query is a compound SELECT and the inner query has a LIMIT clause. Ticket [02a8e81d44]. (check-in: f96782b3 user: drh tags: trunk)
16:45
Allow writers to write dirty pages to the log mid-transaction in order to free memory. (check-in: ecd828f9 user: dan tags: wal)
13:33
Merge two leaves on the WAL branch. (check-in: c9ed66cc user: dan tags: wal)
13:29
The query planner fix of check-in [33b1f584ef] should have been on the trunk. (check-in: f538d759 user: drh tags: trunk)
12:36
Fix a problem in the result set size estimation logic of the query planner - a problem introduced by the two previous changes. (check-in: 33b1f584 user: drh tags: wal)
10:58
Change the way checksums are calculated. (check-in: 84955c2e user: dan tags: wal)
02:37
Bring over the recent query planner enhancements from the trunk. (check-in: 82969f27 user: drh tags: wal)
01:04
Further refinements to table order selection on join query planning. (check-in: defaf0d9 user: drh tags: trunk)
2010-04-14
19:01
The query planner uses non-indexable WHERE clause terms to reduce the estimated number of output rows, then uses the estimated number of output rows as a tie-breaker when choosing table order. (check-in: b87cb0c2 user: drh tags: trunk)
18:50
Add tests and fix bugs in WAL locking mechanism. (check-in: c18077f2 user: dan tags: wal)
18:06
Add tests to check inter-process WAL locking. (check-in: 9435f313 user: dan tags: wal)

Fix other problems in the WAL test scripts. (check-in: dcb31181 user: dan tags: wal)

Fix test script issues preventing walthread.test from running. (check-in: d90b1dde user: dan tags: wal)
11:18
Fix a pager bug introduced by the wal code. (check-in: 4a0b29dc user: dan tags: wal)
06:20
Sync wal branch with [012cf101bf]. (check-in: 9d690f24 user: dan tags: wal)
06:18
Test that the rollback-hook is invoked if a commit-hook implementation returns non-zero (causing a rollback). Remove documentation comment that says otherwise from sqlite.h.in. (check-in: 012cf101 user: dan tags: trunk)
2010-04-12
20:54
Add e_fts3.test to the set of tests excluded from the inmemory_journal exclusion list, since it does simulated OOM errors which trigger I/O errors and SQLite is unable to recover from I/O errors without a persistent journal. (check-in: e7e7127f user: drh tags: trunk)
19:44
Recent changes cause the xSync method of the memory journal implementation to be used, so remove the assert(0). (check-in: 1f2cb940 user: drh tags: trunk)
19:43
Clear a global variable in e_fts3.test before it is used. (check-in: ae89dfd2 user: drh tags: trunk)

19:00
Import experimental write-ahead-logging code. (check-in: 409d61ba user: dan tags: wal)
17:08
Fix a problem where a process in exclusive mode could delete a hot-journal file without rolling it back from within sqlite3_close() or DETACH. This problem was introduced by commits from the past few days; it is not present in any release. (check-in: 51a61395 user: dan tags: trunk)
14:51
Reset the simulated device in the test harness to its default configuration whenever it is restarted. (check-in: 562d20e6 user: drh tags: trunk)
2010-04-10
17:52

2010-04-09
23:05

15:34
Candidate fix for a pager bug associated with sqlite3PagerMovepage(). (check-in: 8c046eb6 user: drh tags: trunk)
09:14
Avoid unnecessary calls to sqlite3_step() with null prepared statements while parsing the schema. (check-in: ae04d2d1 user: drh tags: trunk)
2010-04-08
17:35
Fix a typo in a comment. No changes to code. (check-in: 332cb551 user: drh tags: trunk)
17:28
Fix code coverage problems in where.c. (check-in: b04a5282 user: drh tags: trunk)
16:30
Additional automatic index tests. (check-in: 99d8e325 user: drh tags: trunk)
15:01
New test cases for automatic indices. New testcase() macros associated with column-used bitmasks. (check-in: e1aa48ac user: drh tags: trunk)
15:01
Fix the computation of the number of rows in a table during automatic index generation. (check-in: edeab06a user: drh tags: trunk)
14:38
Fix an integer overflow bug in the automatic index logic. The bug was detected by the testcase() macros added in the previous check-in. Also add some more testcase() macros, since this issue points up their importance. (check-in: af97b488 user: drh tags: trunk)
14:15
Add testcase() macros to the automatic index logic to insure that boundary cases are tested. (check-in: 72865478 user: drh tags: trunk)
11:35
Make sure F_OK, R_OK, and W_OK are defined in test_demovfs.c. Define them manually if they are not. This is necessary to get the module to compile on some systems. (check-in: 7c8afc32 user: drh tags: trunk)
01:16
Merge automatic index changes into the trunk. (check-in: bf7b8d86 user: drh tags: trunk)

2010-04-07
20:32
Pull over the latest changes from the trunk. (check-in: e388fe8b user: drh tags: experimental)
20:29
When rolling back a savepoint to the beginning of the transaction, make sure to initialize the database size in the btree layer correctly even if the database size field of the header is zeroed. (check-in: a3540c6a user: drh tags: trunk)
