| 03:20 | If the keyword "unordered" appears at the end of the SQLITE_STAT1.STAT column for an index, then use that index for equality lookups only, never for range queries or sorting. This feature is currently undocumented and my change or be removed in a future release. (check-in: 8a42e236 user: drh tags: trunk) | |
| 03:04 | Back out the SQLITE_OMIT_UNIQUE_ENFORCEMENT compile-option. It is an unneeded complication. (check-in: 927e955b user: drh tags: trunk) | |

| 23:04 | Make sure the left-hand side of the IS NOT NULL operator is a simple column and not a general expression before applying the IS NOT NULL optimization. This is a backport of check-in [543f75a6abe3]. (check-in: e8177e01 user: drh tags: branch-3.7.2) | |
| 21:35 | Always make sure the left-hand side of the IS NOT NULL operator is a simple column, not a general expression, before applying the IS NOT NULL query optimization. (check-in: 543f75a6 user: drh tags: trunk) | |

| 23:39 | Fix VC++ compiler warnings. (check-in: 7b7c8d36 user: drh tags: sessions) | |
| 22:33 | Merge in the latest changes from the trunk. (check-in: 435b57dc user: drh tags: sessions) | |
| 22:05 | Fix a performance regression: Keep two btree masks in each prepared statement; one for btrees used and another for btrees that require locks. Only try to lock the btrees identified by the second mask. (check-in: 614de91a user: drh tags: trunk) | |
|
2011-04-05
| ||
| 22:13 | Merge the latest trunk changes into the sessions branch. (check-in: 45f20261 user: drh tags: sessions) | |
| 22:10 | Merge the latest trunk changes into the apple-osx branch. (check-in: c77a767c user: drh tags: apple-osx) | |

| 18:34 | Remove dead code from the OP_JournalMode opcode in the VDBE. This code seems to have been useless since [f88c6367d2] on 2010-08-07. (check-in: a89f24e2 user: drh tags: trunk) | |
| 17:31 | Remove the mutex counter and the logic that attempts to verify that btree mutexes are held continuously. We are not making that assumption at this time. (check-in: 242ce7cf user: drh tags: trunk) | |

| 13:27 | Pull the latest trunk changes (and hence the schema-parse-refactor changes) into the sessions branch. (check-in: 03ca8342 user: drh tags: sessions) | |
| 13:12 | Merge the scheme-parse-refactor changes into trunk: (1) added sqlite3SchemaMutexHeld() asserts, (2) Use -1 instead of 0 to mean "all" in sqlite3ResetInternalSchema(), and other cosmetic changes. (check-in: 5db4511d user: drh tags: trunk) | |
| 12:25 | Fix the P4_TRANSIENT constant so that it works correct - so that it really makes a copy of the string for the P4 argument. Use P4_TRANSIENT wherever appropriate. Change P4_STATICs of schema names to P4_TRANSIENT. (check-in: bf664b20 user: drh tags: trunk) | |
| 11:26 | Improved comment on the sqlite3SrcListLookup function. (check-in: bcbc9ff5 user: drh tags: trunk) | |

| 20:40 | Minor comment typo corrections. Simplify an assert. No functional changes. (check-in: 82c23162 user: drh tags: schema-parse-refactor) | |
| 18:22 | Add a description of access rules for the Schema object and lots of asserts to verify that the access rules are followed. (check-in: ae8374af user: drh tags: schema-parse-refactor) | |
| 17:56 | • Edit [a97e8505f229e05b|a97e8505]: Edit check-in comment. (artifact: c2d90aa0 user: drh) | |
| 13:40 | Rename sqlite3SchemaFree() to sqlite3SchemaClear() to more accurately reflect its function. (check-in: 71d74400 user: drh tags: schema-parse-refactor) | |

| 13:11 | Merge in the latest changes from trunk. (check-in: 6d78a25d user: drh tags: apple-osx) | |
| 13:07 | Merge in the latest changes from trunk. (check-in: 47b79c40 user: drh tags: schema-parse-refactor) | |
| 12:29 | Move the expired-statement test for OP_Function until after all memory has been freed. The test is still commented out, however. (check-in: 425e3edb user: drh tags: trunk) | |
| 03:27 | Suppress unused parameter warnings in sqlite3VdbeEnter() and related routines. (check-in: f8e98ab3 user: drh tags: trunk) | |
| 00:14 | Remove the BtreeMutexArray object - use the Vdbe.btreeMask field to accomplish the same result. Add a generation counter to btree mutexes in order to assert that mutexes are never temporarily dropped over a range of instructions in order to do deadlock avoidance in some subroutine. Lock all btrees in any Vdbe program that uses OP_ParseSchema. (check-in: d81708f7 user: drh tags: trunk) | |
|
2011-04-03
| ||
| 18:19 | Make sure that the constant 1 is cast to yDbType before shifting to create an attached database mask. This check-in is a follow-up and fix to the [7aaf8772274422] change that increases the maximum number of attached databases from 30 to 62. (check-in: e2a09ea7 user: drh tags: trunk) | |
| 02:41 | Fix typos in comments. No changes to code. (check-in: 28c5f12e user: drh tags: trunk) | |
|
2011-04-02
| ||
| 20:08 | Merge in the latest changes from trunk. (check-in: 0d99229a user: drh tags: schema-parse-refactor) | |
| 20:01 | Change the name of the "tAttachMask" datatype to "yDbMask". (check-in: 3d6f2e82 user: drh tags: trunk) | |
| 16:50 | When resetting any non-TEMP schema, also reset the TEMP schema since it might be holding references to the non-TEMP schema that just got reset. (check-in: 211d5dde user: drh tags: schema-parse-refactor) | |
| 16:28 | Begin a series of changes designed to reduce the scope and frequency of invalidating schemas. Design goals are that the internal schema should never be deleted out from under a prepared statement that is running and that all prepared statements should be expired if the schema is invalidated. At the same time, minimize the number of schema invalidations. This change merely revises the sqlite3ResetInternalSchema() function to use -1 as the wildcard for "all" rather than 0, so that we can reset the main schema independently of all the others. (check-in: 6a8ad6e3 user: drh tags: schema-parse-refactor) | |
|
2011-04-01
| ||
| 23:49 | Add the "wholenumber" virtual table module to the test suite - useful in populating tables with many rows of content prior to a test. (check-in: 975dff15 user: drh tags: trunk) | |
| 20:54 | Fix up the Makefile.in so that the configuration script works for "make test". (check-in: 2e03830c user: drh tags: trunk) | |

| 18:39 | Merge the multiplexer enhancements back into the trunk. (check-in: 2c125710 user: drh tags: trunk) | |
| 18:12 | Add a script that will break the amalgamation source file up into 4 or 5 smaller source files, each 32K lines or fewer, and a single "sqlite3-all.c" source file that #includes the others. (check-in: 5d34e64d user: drh tags: trunk) | |
| 14:26 | • Edit [365896cb0868fa47|365896cb]: Mark "Closed". (artifact: 9f02daec user: drh) | |
