Give the same access permissions to journal files as is given to databases. (CVS 2590) (check-in: 7961ec0ccb user: drh tags: trunk)
16:13
Disable an overzealous optimization the omitted sorting on a join if the first table gave a unique result. The sort can only be omitted if all tables in the join are unique. Ticket #1358. (CVS 2589) (check-in: 4f07661279 user: drh tags: trunk)
13:40
Fix a comment in printf. (CVS 2588) (check-in: 1054685f15 user: drh tags: trunk)
13:39
Additional cleanup and optimization of the printf function. (CVS 2587) (check-in: 240bb04900 user: drh tags: trunk)
12:59
Add the "!" flag to the "%g" mprintf conversion parameter to force a decimal point. This prevents floating point values from appearing as integers. Use this flag when converting floating point to text. Ticket #1362. (CVS 2586) (check-in: 4b98dace6b user: drh tags: trunk)

2005-08-12
23:20
3rd argument to sqlite3Error() should always be a format string, never user-supplied error message text. Ticket #1354. (CVS 2583) (check-in: d6146a542a user: drh tags: trunk)
22:58

2005-08-11
02:10
Improve the error message associated with SQLITE_FULL. Ticket #1353. Also remove error messages for obsolete error codes SQLITE_INTERNAL, SQLITE_NOTFOUND, and SQLITE_TOOBIG. (CVS 2580) (check-in: fa7403c7d9 user: drh tags: trunk)
01:25

2005-07-29
19:43

Fix authentication so that it works with AS aliases. Ticket #1338. (CVS 2570) (check-in: cc7ae73ed0 user: drh tags: trunk)
15:10
Optimizer now converts OR-connected WHERE-clause terms into an IN operator so that they can be used with indices. There are known problems with the ORDER BY optimization in this and in several prior check-ins. This check-in is not recommended for production use. (CVS 2569) (check-in: d23c8bf81e user: drh tags: trunk)
2005-07-28
23:12
The BETWEEN operator in a WHERE clause is now able to use indices. (CVS 2568) (check-in: cdf8c9584b user: drh tags: trunk)

20:41
More work on the new optimizer. Fewer tests fail now. (CVS 2565) (check-in: ee3a08e353 user: drh tags: trunk)
2005-07-23
22:59
A new optimizer that breaks a lot of tests. But none of them critically, I think. Nevertheless, there is a lot of work ahead to stabilize the code. (CVS 2564) (check-in: 86ce56ccea user: drh tags: trunk)
14:52
Store the total number of rows as part of the ANALYZE statistics. (CVS 2563) (check-in: 868279c78e user: drh tags: trunk)

02:17
Full-coverage testing and documentation for the ANALYZE command. The results of analysis are still not loaded or used, however. (CVS 2561) (check-in: bd7583a5d6 user: drh tags: trunk)
00:41
First code for the ANALYZE command. Mostly untested. The analysis is not loaded into the symbol tables and is not used by the optimizer. (CVS 2560) (check-in: a4886b114d user: drh tags: trunk)
2005-07-22

22:53
Correct the documentation to show that sqlite3_column_text() returns a NULL pointer (not an empty string) when the column value is NULL. The same goes for sqlite3_column_blob(). Ticket #1334. (CVS 2558) (check-in: fd1e013a14 user: drh tags: trunk)
00:31
Begin adding code to support multiple IN constraints on the same index. (CVS 2557) (check-in: 103f8ccb90 user: drh tags: trunk)
2005-07-21
18:23
Split the OP_Integer opcode into OP_Integer and OP_Int64. This allows comments to be added to OP_Integer. Cleanup in the optimizer. Allow terms of the FROM clause to be reordered automatically. (CVS 2556) (check-in: e2f822ac82 user: drh tags: trunk)
03:48

More refactoring in where.c. (CVS 2552) (check-in: a35bd50af8 user: drh tags: trunk)
17:38
Refactoring of the query optimizer in advance of adding better optimization. (CVS 2551) (check-in: 57c6bd3760 user: drh tags: trunk)
2005-07-16

Allow an unlimited number of terms in the WHERE clause. The old limit was 100. (CVS 2550) (check-in: ca69f36832 user: drh tags: trunk)
2005-07-15
23:24
Fix bugs in the new query plan instrumention logic. (CVS 2549) (check-in: 578490c913 user: drh tags: trunk)
13:05
Add test instrumentation that will be needed during the development of forthcoming optimizer enhancements. (CVS 2548) (check-in: dfd5fd77b0 user: drh tags: trunk)
2005-07-09
23:11
Add remark in the changelog that mentions 64-bit alignment fixes in 3.2.2. (CVS 2547) (check-in: ead583cfad user: drh tags: trunk)

Use the internal sqlite3_snprintf function instead of sprintf to avoid cross-platform incompatibilities. Ticket #1316. (CVS 2545) (check-in: 431999da7b user: drh tags: trunk)
02:23
Patch to Makefile.in so that it works with OS X. Ticket #1292. (CVS 2544) (check-in: 0dfabca641 user: drh tags: trunk)
02:16
Make sure there is only one busy counter. Ticket #1315. (CVS 2543) (check-in: af2a0ba4a3 user: drh tags: trunk)
2005-07-08
18:25
Allow the IN operator to take a list of arbitrary expressions on its right-hand side. The expressions no longer need to be constant. The current implementation seems to work but needs more testing and optimization. (CVS 2542) (check-in: ba56478dd8 user: drh tags: trunk)
17:13
Change the name of the OpenTemp opcode to OpenVirtual which is more descriptive of what it does. (CVS 2541) (check-in: 3bb9ce5f20 user: drh tags: trunk)
