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.

| 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) | |

| 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) | |
|

| ||
| 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) | |

| 21:27 | Change the default temp file prefix to be "sqlite" spelled backwards. Tickets #2049 et al. (CVS 3499) (check-in: a19ce5c1c4 user: drh tags: trunk) | |
| 21:16 | Change the default prefix for temporary files so that it no longer contains the text "sqlite". In this way, perhaps we will not get so many false bug reports such as ticket #2049, #1989, and #1841. (CVS 3498) (check-in: 7ce48000bb user: drh tags: trunk) | |
| 18:13 | Fix a pair of memory leaks. These were turned up by running valgrind memcheck with various 10k doc insert, update, delete, and query tests. (CVS 3497) (check-in: 3cd9b64b96 user: shess tags: trunk) | |

| ||
| 18:15 | Bring CVS output into more commonly accepted practice. Tickets #2030, #1573. Add command-line options -bail and ".bail" commands. Default behavior is to continue after encountering an error. Ticket #2045. (CVS 3491) (check-in: 517712d6fb user: drh tags: trunk) | |
| 14:25 | Command-line shell enhancements. Bail out when errors are seen in non-interactive mode. Override isatty() using -interactive or -batch command-line options. Report line number in error messages. Tickets #2009, #2045. (CVS 3490) (check-in: 3baa04cfb9 user: drh tags: trunk) | |
| 00:41 | Empty queries should get no results. My recent change ( http://www.sqlite.org/cvstrac/chngview?cn=3486 ) broke test fts2a-5.3. This change should make the expected result more obvious. (CVS 3489) (check-in: cde383eb46 user: shess tags: trunk) | |
| 00:04 | Make memset() uses less error-prone. http://www.sqlite.org/cvstrac/tktview?tn=2036,35 describes some cases where we were passing memset() a length which was the sizeof a pointer, rather than the structure pointed to. Instead, wrap this idiom up in CLEAR() and SCRAMBLE() macros. (CVS 3488) (check-in: 5878add083 user: shess tags: trunk) | |

| 23:22 | Remove unreferenced local variable. (CVS 3487) (check-in: 2d3b22197c user: shess tags: trunk) | |
| 21:00 | Replace the DocList and DocListReader structures. The new structures distinguish reading from a static buffer from writing to a dynamic buffer. This allows n-way doclist merging, and in-place merging of segment leaf nodes, which together cut segment merge times in half. (CVS 3486) (check-in: af5bfb986e user: shess tags: trunk) | |
| 20:27 | Test to force edge cases in query logic. Basically, exercise code to handle lack of hits correctly. (CVS 3485) (check-in: 2cb5903366 user: shess tags: trunk) | |
| 05:21 |
Don't store empty segments. When inserting empty strings, the code
was writing out a segment made up of a single leaf node containing the
\0 header. LeafReader assumed that leaf nodes always contained at
least one term, so assertions would fail.
While it would be possible to support reading and merging empty segments, there's no reason to do so. While this change could have been done in writeZeroSegment(), I put it in leafWriterFlush() so that it would work right if segmentMerge() created an empty segment, which could happen with future changes to how deleted documents are handled.

| 12:25 | Avoid expanding %d contained in the action of a lemon parser rule. Ticket #1063. This is a fix for lemon only. It does not effect SQLite. (CVS 3476) (check-in: 81daedcf48 user: drh tags: trunk) | |

2006-10-12

| 23:15 | Convert fts2 to store data in a way which allows for much faster updates. Groups of documents form segments which are encoded in a btree layered over a table of blocks, with various tricks to make merges fast. This performs 20x-25x faster than fts1 when loading the Enron corpus, and is only slightly slower for queries. (CVS 3474) (check-in: 85272b2f53 user: shess tags: trunk) | |

| 21:48 | Fix incorrect doclist initialization in term_select_all(). docListRestrictColumn() generates a DL_POSITIONS doclist, which means that after the first doclist is processed, the second doclist is initialized as DL_POSITIONS, but with DL_POSITIONS_OFFSETS data.
