14 check-ins for the month beginning 2006-10-01 by user shess
Following month ↑|
2006-10-31
| ||
| 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: 3cd9b64b user: shess 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: cde383eb 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: 5878add0 user: shess tags: trunk) | |

| 23:22 | Remove unreferenced local variable. (CVS 3487) (check-in: 2d3b2219 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: af5bfb98 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: 2cb59033 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. (CVS 3484) (check-in: fed79bee user: shess tags: trunk) | |

| 23:36 | dup fts1 tests and edit for fts2. fts1porter.test omitted because it depends on being able to poke through to %_term table. (CVS 3482) (check-in: 2806c341 user: shess tags: trunk) | |
| 23:28 | Add tests for delete and update in fts1. (CVS 3481) (check-in: b01c4371 user: shess tags: trunk) | |
| 20:27 | fts2 support for testing. These are a prelude to adding some test scripts. (CVS 3480) (check-in: 004ad194 user: shess 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: 85272b2f user: shess tags: trunk) | |
|
2006-10-10
| ||
| 23:22 | Fix leaky symbols. With this change, fts1 and fts2 can both be statically linked. (CVS 3472) (check-in: 5e8bbb85 user: shess tags: trunk) | |
| 17:37 |
Copy fts1/ to fts2/, changing reference from fts1 to fts2. For future
reference, the source versions copied were:
README.txt r1.1 fts1.c r1.37 fts1.h r1.2 fts1_hash.c r1.1 fts1_hash.h r1.1 fts1_porter.c r1.1 fts1_tokenizer.h r1.4 fts1_tokenizer1.c r1.6 (CVS 3471) (check-in: d0d1e7cd user: shess tags: trunk) | |
|
2006-10-05
| ||
| 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. (Note that DL_DEFAULT is now DL_POSITIONS, which masks this bug.) (CVS 3467) (check-in: 144e3f11 user: shess tags: trunk) | |
