Add performance tests to the test suite. (CVS 3516) check-in: 270c745d user: drh tags: trunk

Fix the ".dump" command in the shell. Ticket #2072. Also ticket #2065. (CVS 3515) check-in: 9fdc2496 user: drh tags: trunk

Make sure VACUUM cleans up after itself. Ticket #2071. (CVS 3514) check-in: 2fdc147d 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: f6e0b080 user: shess tags: trunk

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: f30771d5 user: shess tags: trunk

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: 9b6d413d 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: 64b7e340 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: 9628a61a user: shess tags: trunk

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: b9dd16ef 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: d9e14b61 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: f1efae92 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: f39978ef user: drh tags: trunk
2006-11-07
15:02
Fix a typo in os_win.c. Ticket #2055. (CVS 3504) check-in: d309680e user: drh tags: trunk
2006-11-06

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: 6324ea81 user: drh tags: trunk
