| 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) | |
|
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) | |
|
2006-10-31
| ||
| 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) | |
| 18:08 | Make the command-line shell ".dump" command more resilient in the face of database corruption. (CVS 3496) (check-in: ebd44f0b5e user: drh tags: trunk) | |
|
2006-10-30
| ||
| 13:37 | Changes to support non-ASCII characters in win95 filenames. Ticket #2047. (CVS 3495) (check-in: 9fa3ae584a user: drh tags: trunk) | |
|
2006-10-28
| ||
| 00:28 | Enhance the optimizer so that IS NULL can use an available index. (CVS 3494) (check-in: 64762a9d58 user: drh tags: trunk) | |
|
2006-10-27
| ||
| 14:21 | Fix the ".dump" command in the command-line shell so that it shows TRIGGERs and VIEWs. Ticket #2044. (CVS 3493) (check-in: 58171a41f7 user: drh tags: trunk) | |
| 14:06 | Changes directed toward optimizing IS NULL terms in WHERE clauses. (CVS 3492) (check-in: 4d336e9ef5 user: drh tags: trunk) | |
|
2006-10-26
| ||
| 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. (CVS 3484) (check-in: fed79beec7 user: shess tags: trunk) | |
|
2006-10-24
| ||
| 11:26 | Fix a bad variable reference. The reference is actually in unreachable code and is therefore harmless. The fix is to remove the code. (CVS 3483) (check-in: 46b91807f7 user: drh tags: version_2) | |
|
2006-10-19
| ||
| 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: 2806c34158 user: shess tags: trunk) | |
| 23:28 | Add tests for delete and update in fts1. (CVS 3481) (check-in: b01c4371d8 user: shess tags: trunk) | |
| 20:27 | fts2 support for testing. These are a prelude to adding some test scripts. (CVS 3480) (check-in: 004ad1943f user: shess tags: trunk) | |
| 01:58 | When converting UTF8 or UTF16 strings, change overlong strings and other illegal codes to 0xFFFD. Ticket #2029. (CVS 3479) (check-in: 0c6736df9c user: drh tags: trunk) | |
|
2006-10-18
| ||
| 23:26 | Fix a problems that arise if malloc() fails while compiling SELECT statements within a TRIGGER. (CVS 3478) (check-in: ee4894b499 user: drh tags: trunk) | |
|
2006-10-13
| ||
| 15:34 | Make sure the names of all expressions in compound SELECT statements used as subqueries are correctly resolved. Ticket #2018. (CVS 3477) (check-in: b886eaa334 user: drh tags: trunk) | |
| 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) | |
| 11:55 | Removing debugging printf from the porter stemmer code. Ticket #2016. (CVS 3475) (check-in: 7a08c6272f 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) | |
|
2006-10-11
| ||
| 17:19 | Bug fix: named local variable lockStyle as lockingStyle in SQLITE_ENABLE_LOCKING_STYLE block in allocateUnixFile (CVS 3473) (check-in: aa0b96c3df user: aswift 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: 5e8bbb85c1 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: d0d1e7cdcc user: shess tags: trunk) | |
| 13:07 | VACUUM now uses a temporary file in the official TEMP folder instead of a file in the same directory as the original database. (CVS 3470) (check-in: b743429dd5 user: drh tags: trunk) | |
|
2006-10-09
| ||
| 00:38 | Version 3.3.8 (CVS 3469) (check-in: 0658bb9e3f user: drh tags: trunk) | |
|
2006-10-08
| ||
| 18:56 | Website changes for version 3.3.8. Remove a C++-ism from test8.c. (CVS 3468) (check-in: 465ce5b2fe user: drh 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: 144e3f11e2 user: shess tags: trunk) | |
| 11:43 | Fix another UTF conversion problem on x64. Ticket #2008. (CVS 3466) (check-in: d16523e555 user: drh tags: trunk) | |
|
2006-10-04
| ||
| 17:35 | The snippet generator adds ellipsis between text from different columns. (CVS 3465) (check-in: 6cf1fb9f80 user: drh tags: trunk) | |
| 15:23 | Fix UTF conversions for -O2 on gcc 4.1.1. Ticket #2008. (CVS 3464) (check-in: 86a08bb7c5 user: drh tags: trunk) | |
| 11:55 | Tests cases automatically remove many of their temporary files. (CVS 3463) (check-in: eef0ec0d7a user: drh tags: trunk) | |
|
2006-10-03
| ||
| 19:37 | Make DL_POSITION the default mode in FTS1. Remove the need to compile with SQLITE_CORE when SQLITE_ENABLE_FTS1 is used. (CVS 3462) (check-in: df1a4b4834 user: drh tags: trunk) | |
