2006-11-30
| ||
| 13:06 | Change the table_info pragma so that it returns NULL for the default value if there is no default value. Ticket #2078. (CVS 3527) (check-in: 5f21c3a5f0 user: drh tags: trunk) | |
| 13:06 | Improvements to the new performance tests. (CVS 3526) (check-in: 27f56c2051 user: drh tags: trunk) | |
| 13:05 | Fix indentation typo in btree.c. (CVS 3525) (check-in: 5d61486f0f user: drh tags: trunk) | |
|
2006-11-29
| ||
| 23:41 | Drop a couple variables which are no longer used anywhere. (CVS 3524) (check-in: 08c2cc0e07 user: shess tags: trunk) | |
| 21:03 | Test that terms longer than interior nodes work correctly. A bug prior to fts2.c r1.10 meant that such large terms caused an eventual stack overflow. (CVS 3523) (check-in: 66581162da user: shess tags: trunk) | |
| 20:53 | Added the speed1.test script (CVS 3522) (check-in: 30355dfbd9 user: drh tags: trunk) | |

The virtual table interface allows for a cursor to field multiple xFilter() calls. For instance, if a join is done with a virtual table, there could be a call for each row which potentially matches. Unfortunately, fulltextFilter() assumes that it has a fresh cursor, and overwrites a prepared statement and a malloc'ed pointer, resulting in unfinalized statements and a memory leak. This change hacks the code to manually clean up offending items in fulltextFilter(), emphasis on "hacks", since it's a fragile fix insofar as future additions to fulltext_cursor could continue to have the problem. (CVS 3521) (check-in: 18142fdb6d user: shess tags: trunk) | |
| 01:02 | Delta-encode terms in interior nodes. While experiments have shown that this is of marginal utility when encoding terms resulting from regular English text, it turns out to be very useful when encoding inputs with very large terms. (CVS 3520) (check-in: c8151a998e user: shess tags: trunk) | |

| 21:09 | Improvements to the speed tests recently added to the test suite. (CVS 3519) (check-in: 272c1a6e61 user: drh tags: trunk) | |
| 11:59 | Fix a typo in the OMIT_AUTORIZATION in expr.c. (CVS 3518) (check-in: 3dea7fbefd user: drh tags: trunk) | |
| 11:58 | Make the pager sector size configurable at compile-time. (CVS 3517) (check-in: 6221cf4f52 user: drh tags: trunk) | |
| 09:39 | Add performance tests to the test suite. (CVS 3516) (check-in: 270c745dff user: drh tags: trunk) | |
|
2006-11-20
| ||
| 16:21 | Fix the ".dump" command in the shell. Ticket #2072. Also ticket #2065. (CVS 3515) (check-in: 9fdc249609 user: drh tags: trunk) | |
|
2006-11-18

| 20:20 | Make sure VACUUM cleans up after itself. Ticket #2071. (CVS 3514) (check-in: 2fdc147d00 user: drh tags: trunk) | |
| 00:12 | Store minimal terms in interior nodes. Whenever there's a break between leaf nodes, instead of storing the entire leftmost term of the rightmost child, store only that portion of the leftmost term necessary to distinguish it from the rightmost term of the leftmost child. (CVS 3513) (check-in: f6e0b080dc user: shess tags: trunk) | |
|
2006-11-17
| ||
| 21:12 | Refactoring groundwork for coming work on interior nodes. Change LeafWriter to use empty data buffer (instead of empty term) to detect an empty block. Code to validate interior nodes. Moderate revisions to leaf-node and doclist validation. Recast leafWriterStep() in terms of LeafWriterStepMerge(). (CVS 3512) (check-in: f30771d5c7 user: shess tags: trunk) | |
|
2006-11-13

| 21:09 | Delta-encode docids. This is good for around 22% reduction in index size with DL_POSITIONS. It improves performance about 5%-6%. (CVS 3511) (check-in: 9b6d413d75 user: shess tags: trunk) | |
| 21:00 | Require a minimum fanout for interior nodes. This prevents cases where excessively large terms keep the tree from finding a single root. A downside is that this could result in large interior nodes in the presence of large terms, which may be prone to fragmentation, though if the nodes were smaller that would translate into more levels in the tree, which would also have that problem. (CVS 3510) (check-in: 64b7e34061 user: shess tags: trunk) | |
| 20:15 | Allow backing tables to be missing on dropping fts table. Fixes http://www.sqlite.org/cvstrac/tktview?tn=1992,35 . (CVS 3509) (check-in: 9628a61a6f user: shess tags: trunk) | |
|
2006-11-11
| ||
| 01:31 | The uninitialized file descriptor from the unixFile structure is passed to sqlite3DetectLockingStyle in allocateUnixFile rather than the file descriptor passed in. This was causing the locking detection on NFS file systems to behave somewhat randomly and the result was locks were not respected and data loss could occur. (CVS 3508) (check-in: b9dd16ef3d user: aswift tags: trunk) | |
|
2006-11-09
| ||
| 15:18 | Update the documentation to talk about the new sqlite3_prepare_v2() API. (CVS 3507) (check-in: d9e14b6121 user: drh tags: trunk) | |
| 00:24 | First cut at adding the sqlite3_prepare_v2() API. Test cases added, but more testing would be useful. Still need to update the documentation. (CVS 3506) (check-in: f1efae9224 user: drh tags: trunk) | |
|
2006-11-08
| ||
| 12:25 | Make the .exit and .quit commands work again in the shell. Ticket #2056. (CVS 3505) (check-in: f39978ef13 user: drh tags: trunk) | |
|
2006-11-07
| ||
| 15:02 | Fix a typo in os_win.c. Ticket #2055. (CVS 3504) (check-in: d309680ec7 user: drh tags: trunk) | |
|
2006-11-06
| ||
| 21:20 | Use the difference between the SQLITE_IOERR_SHORT_READ and SQLITE_IOERR_READ returns from sqlite3OsRead() to make decisions about what to do with the error. (CVS 3503) (check-in: 6324ea811e user: drh tags: trunk) | |
| 15:10 | Fix a bug in the optimizer that was causing it to miss an OR optimization opportunity. (CVS 3502) (check-in: 9bf153b54c user: drh tags: trunk) | |
|
2006-11-01
| ||
| 12:20 | Modify Makefile.in to install sqlite3ext.h. (CVS 3501) (check-in: 35c8c47817 user: drh tags: trunk) | |
| 12:08 | Remove dead code from btree.c. Ticket #2050. (CVS 3500) (check-in: dbd0125c62 user: drh tags: trunk) | |
