Be sure to initialize the sqlite3_rtree_query_info.iRowid field for the leaves of the R-Tree when doing a query callback search. check-in: 43946938 user: drh tags: rtree-enhancements

Omit the sqlite3GetReservedNoMutex() routine in build configurations where it is not used. check-in: f193dbb6 user: drh tags: trunk
12:16
Make sure the size parameter to read and write VFS methods in the unix VFS do not become too big or go negative. This was not actually possible in the current code. The checks are added to make sure some future bug does not make it possible. check-in: daebe3bd user: drh tags: trunk
06:50
Ensure that the value returned by xSectorSize() is reasonable (currently defined as between 2^5 and 2^16 bytes) before using it to calculate the amount of padding to add to a wal file. check-in: 6b4ff83b user: dan tags: trunk

20:23
Avoid calling sqlite3BtreeEnter() in a corner case where the corresponding database handle mutex (sqlite3.mutex) may not be held. This prevents a potential deadlock or crash that can occur if the backup API, shared-cache mode and SQLITE_HAVE_CODEC are all in use. check-in: 89b8c377 user: dan tags: trunk
18:13
Modify the clearCell function to use SQLITE_CORRUPT_BKPT in the one place it was not. check-in: 472beb30 user: mistachkin tags: trunk
13:05
Merge the latest trunk changes (especially "PRAGMA busy_timeout" and the ORDER BY query planner optimizations) into the sessions branch. check-in: 6ca8eae1 user: drh tags: sessions
12:55
Update the sessionfault-9.1 and -9.2 tests to account for the change in version 3.7.11 in which a pending statement no longer blocks ROLLBACK but instead causes the next call on that statement to return SQLITE_ABORT. check-in: fae9eb19 user: drh tags: sessions
00:44
Query planner enhancements to be more agressive about optimizing out ORDER BY clauses - in particular the query planner now has the ability to omit ORDER BY clauses that span multiple tables in a join. check-in: 1e874629 user: drh tags: trunk
2012-09-27
23:27
Fix some corner case behavior in the new ORDER BY optimization logic. Remove the SQLITE_OrderByIdx bit from the SQLITE_TESTCTRL_OPTIMIZATIONS mask, since enabling it caused many TH3 tests to fail when the NO_OPT configuration parameter was engaged, and since there really isn't any need to turn that optimization off. The SQLITE_OrderByIdxJoin bit remains. Closed-Leaf check-in: 98b63371 user: drh tags: qp-enhancements
21:03
Modify generation of resource header file for MSVC so that it can work from outside the working directory. check-in: 20caf80c user: mistachkin tags: trunk

17:31
Test cases and bug fixes applied to the ORDER BY optimization for joins. Some test cases fail, but except for the new orderby1.test failures, all failures appear to be issues with the tests, not with the core code. check-in: 75cda864 user: drh tags: qp-enhancements
15:05
Add more bits to the bit vector that is used to disable optimizations for built-in test. Add specific bit patterns to disable ORDER BY using an index in general and for joins. Use macros to test for bits in the disabled-optimization bit vector, in order to make the code clearer. check-in: d2fcba1e user: drh tags: qp-enhancements
14:11
Enable ORDER BY clauses that span joins to be optimized out. check-in: c29538f9 user: drh tags: qp-enhancements

23:17
Further refactoring of the ORDER BY related query-planning logic in order to make it easier to extend to support optimizing out ORDER BY on joins. No actual behavior changes, yet. check-in: 96496dda user: drh tags: qp-enhancements
2012-09-25
20:43
Augment the WhereBestIdx structure to pass down into the query planner information that might be used to better detect ORDER BY and DISTINCT optimizations spanning multiple tables of a join. check-in: 4226e51f user: drh tags: qp-enhancements
14:29
Pass information around between the major routines of the query planner using a single pointer to a structure rather than a long list of parameters. check-in: 1104d42e user: drh tags: qp-enhancements
2012-09-24
19:50
Remove an unused subfunction parameter and an obsolete comment from the query planner logic in where.c. check-in: 349a55cd user: drh tags: trunk
15:30
Change the internal sqlite3WhereBegin() to report that the ORDER BY clause is satisfied by indices using the WhereInfo.nOBSat field of the returned structure. check-in: 22989f35 user: drh tags: trunk
11:43
Update documentation to describe the threadsafety of sqlite3_enable_shared_cache(). check-in: e081890c user: drh tags: trunk
2012-09-21
22:50
Enable query planner tracing using the new (and undocumented) ".wheretrace 1" command in the command-line shell if both the shell and the core are compiled with SQLITE_DEBUG and SQLITE_ENABLE_WHERETRACE. This is not a supported API. Use for testing and debugging only. check-in: 1be4b16b user: drh tags: trunk
13:40
Command-line shell enhancements: Added the ".print" command. Enhanced the ".width" command so that negative widths will right-justify. check-in: a1d8269d user: drh tags: trunk
00:04
Consolidate more of the DISTINCT processing logic into a single spot in the code. Reduce the number of OP_Column operations needed to perform a WHERE_DISTINCT_ORDERED. check-in: 79e922f7 user: drh tags: trunk
2012-09-20
15:41
Continuing incremental enhancements of SELECT code generation: Remove the Select.affinity field. Use SelectDest.affSdst instead. check-in: cf40b7b5 user: drh tags: trunk
14:26
Refactoring of DISTINCT code. Change the name of the local variable "distinct" to "distinctTab". Generate cleaner code w/o unnecessary P4 and P5 values on the OP_Null for WHERE_DISTINCT_ORDERED. check-in: 0cda241a user: drh tags: trunk
2012-09-19
21:15
Tighter VDBE code for the WHERE_DISTINCT_ORDERED case of DISTINCT keyword handling. check-in: 94b48064 user: drh tags: trunk

Silence harmless compiler warning seen with SQLITE_OMIT_DEPRECATED. check-in: c5cee969 user: mistachkin tags: trunk
19:29
Enhance IN processing to allow efficient use of indices with numeric affinities. Add test cases for IN processing that would have spotted the error in the [2be661a48023f4] check-in. check-in: 5ded9b68 user: drh tags: trunk
17:08
Enhancements to the comments on sqlite3FindInIndex(). No code changes. check-in: b1a4c394 user: drh tags: trunk

13:20
Update the vdbe-compress.tcl script so that it accepts variable declarations inside of #ifdef...#endif. This enhancement is needed due to the change of check-in [39866c0ede5d6ef4]. check-in: e7db056a user: drh tags: trunk
2012-09-17

Performance enhancement in the sqlite3VdbeSerialType() routine. check-in: ad298f52 user: drh tags: trunk
2012-09-15
18:45
Attempt to use a covering index even on a full table scan, under the theory that the index will be smaller and require less disk I/O and thus be faster. check-in: cfaa7bc1 user: drh tags: fullscan-covering-index
