43 check-ins using file src/vdbe.c version 2abd931e

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
2010-04-17
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
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
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
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
13:29
The query planner fix of check-in [33b1f584ef] should have been on the trunk. check-in: f538d759 user: drh tags: trunk
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
2010-04-13
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
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
Fix issues and clarify the operation of pager_playback_one_page(). A block comment in pager.c identifies 13 invariants on the pager subsystem. Ticket [9d68c883132c8]. check-in: 09065976 user: drh tags: trunk
2010-04-09
23:05
Add a test case for the OOM-fault corruption issue. Ticket [9d68c883132c8]. check-in: 0a64a937 user: drh tags: trunk
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
00:40
When constructing automatic indices do not include the same column more than once. Closed-Leaf check-in: d067d9f7 user: drh tags: experimental
2010-04-07
20:32
Pull over the latest changes from the trunk. check-in: e388fe8b user: drh tags: experimental
19:32
Add an interface to the SQLITE_STMTSTATUS_AUTOINDEX status information to the TCL bindings. Add some simple automatic index test cases. check-in: 1f404412 user: drh tags: experimental
16:54
Wrap all automatic index changes inside SQLITE_OMIT_AUTOMATIC_INDEX. Add the automatic_index PRAGMA to turn it on and off. check-in: a811a47f user: drh tags: experimental
14:59
Make sure that all automatic indices are covering indices. Otherwise, the table and index might be used together in a query but the table could get out of sync with the automatic index through out-of-band changes. check-in: 23643131 user: drh tags: experimental
14:33
Enhance comments on the SrcList object definition to better explain the operation of the SrcList.a[].colUsed field. No changes to code. check-in: c0f67ea1 user: drh tags: experimental
14:32
Fix the trace output of the OP_Function opcode to show the correct register numbers. check-in: 064c283e user: drh tags: experimental
