| 19:01 | Add PRAGMA 'temp_store_directory'. Added os_*.c function sqlite3OsIsDirWritable(), split pragma.c changeTempStorage() function into invalidateTempStorage(). (CVS 2171) (check-in: 772e22cb user: tpoindex tags: trunk) | |

| 00:11 | The optimizer now uses only the index and ignores the table if it can get away with doing so, thus saving a single BTree search per row of result. This could potentially double the speed of certain queries. The code passes all regression tests but new tests to exercise the new functionality are yet to be added. (CVS 2170) (check-in: e5aa4894 user: drh tags: trunk) | |

| 18:40 | Improvements to the query optimizer. This is a work in progress. (CVS 2169) (check-in: 9b86993f user: drh tags: trunk) | |

| 20:48 | Fix a C++-ism in the previous change to tclsqlite.c. (CVS 2168) (check-in: b49b8fdd user: drh tags: trunk) | |
| 15:41 | Add 'copy' method for tcl interface. Behaves similar to shell .import or COPY statment in 2.x. (CVS 2167) (check-in: a9311d9d user: tpoindex tags: trunk) | |

| 18:00 | Factor the test for zName==NULL out of the loop. Ticket #1032. (CVS 2164) (check-in: 7f38f67c user: drh tags: trunk) | |
| 17:17 | Fix a problem with the automatic generation of the opcode name table. (CVS 2163) (check-in: 9eefabc9 user: drh tags: trunk) | |
| 03:08 | Back out the USE_TCL_STUBS changes because it breaks the build. I think the strategy needs to be to abandon libtool and use tcl.m4 to figure out how to build our own shared libraries. Ticket #1034. (CVS 2162) (check-in: 7f4679b9 user: drh tags: trunk) | |
| 02:20 | Improvements to the --help option to configure. Ticket #1033. (CVS 2161) (check-in: 3032cc2b user: drh tags: trunk) | |
| 02:08 | Add a -DUSE_TCL_STUBS to the standard Makefile. This might help with ticket #1034. Or maybe not. (CVS 2160) (check-in: 4c30c373 user: drh tags: trunk) | |

|
2004-12-07

| 15:41 | Only evaluate expressions once for UPDATE and INSERT statements that have BEFORE triggers. Fix for ticket #980. (CVS 2158) (check-in: 4852186a user: drh tags: trunk) | |
