53 check-ins using file src/vdbeaux.c version 6fcc4798

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: 517712d6 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: 3baa04cf 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: 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
2006-10-25
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
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: 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
01:58
When converting UTF8 or UTF16 strings, change overlong strings and other illegal codes to 0xFFFD. Ticket #2029. (CVS 3479) check-in: 0c6736df 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: ee4894b4 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: b886eaa3 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: 81daedcf user: drh tags: trunk
11:55
Removing debugging printf from the porter stemmer code. Ticket #2016. (CVS 3475) check-in: 7a08c627 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: 85272b2f 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: aa0b96c3 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: 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
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: b743429d user: drh tags: trunk
2006-10-09
00:38
Version 3.3.8 (CVS 3469) check-in: 0658bb9e user: drh tags: trunk
2006-10-08
18:56

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
11:43
Fix another UTF conversion problem on x64. Ticket #2008. (CVS 3466) check-in: d16523e5 user: drh tags: trunk
2006-10-04
17:35
The snippet generator adds ellipsis between text from different columns. (CVS 3465) check-in: 6cf1fb9f user: drh tags: trunk
15:23

11:55
Tests cases automatically remove many of their temporary files. (CVS 3463) check-in: eef0ec0d user: drh tags: trunk
2006-10-03
19:37

19:12
Modify the makefile(s) to know about the FTS1 module - however FTS1 is turned off by default. Bump the version number to 3.3.8. (CVS 3461) check-in: 288ff637 user: drh tags: trunk
19:05
Report the error SQLITE_CORRUPT instead of SQLITE_IOERR if unable to rollback a hot journal that was damaged (for example) by filesystem corruption following a power failure. (CVS 3460) check-in: 70501e4e user: drh tags: trunk
17:40

12:08
Fix sqlite3_analyzer so that it works when compiled against Tcl8.5. (CVS 3458) check-in: e774adce user: drh tags: trunk
12:04
Fix sqlite3_analyzer so that it works on databases containing virtual tables. (CVS 3457) check-in: 47c8567f user: drh tags: trunk
11:42

18:41
Add a Porter stemmer option to the FTS1 module. (CVS 3452) check-in: 936b06aa user: drh tags: trunk
2006-09-29
14:01
