54 check-ins using file src/main.c version b9cf8dd1

2006-10-19
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
Website changes for version 3.3.8. Remove a C++-ism from test8.c. (CVS 3468) (check-in: 465ce5b2 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: 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
Fix UTF conversions for -O2 on gcc 4.1.1. Ticket #2008. (CVS 3464) (check-in: 86a08bb7 user: drh tags: trunk)
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
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: df1a4b48 user: drh tags: trunk)
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
Add the OS-X locking style patches to os_unix.c. Disabled by default. (CVS 3459) (check-in: f4103dea user: drh tags: trunk)
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

2006-10-01

Another typo in the Porter stemmer check-in. (CVS 3455) (check-in: 6696bda1 user: drh tags: trunk)
18:59
Typo in previous check-in. (CVS 3454) (check-in: a7350bf8 user: drh tags: trunk)
18:58
Remove one non-working test case fromthe Porter stemmer tests and add an acknowledgement for the source of the test data (Martin Porter himself.) (CVS 3453) (check-in: 1a2df2a6 user: drh tags: trunk)
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

20:36

2006-09-22
23:38
Fix a build problem around sqlite3_overload_function. Only affects so/dll builds. (CVS 3435) (check-in: 791d7093 user: shess tags: trunk)
00:06
Implemented UPDATE for full-text tables.

We handle an UPDATE to a row by performing an UPDATE on the content table and by building new position lists for each term which appears in either the old or new versions of the row. We write these position lists all at once; this is presumably more efficient than a delete followed by an insert (which would first write empty position lists, then new position lists). (CVS 3434) (check-in: 757fa224 user: adamd tags: trunk)

2006-09-21
20:56
When gathering a doclist for querying, don't discard empty position lists until the end; this allows empty position lists to override non-empty lists encountered later in the gathering process. This fixes #1982, which was caused by the fact that for all-column queries we weren't discarding empty position lists at all. (CVS 3433) (check-in: 111ca616 user: adamd tags: trunk)
11:02
Be more aggressive with the SQLITE_OMIT_VACUUM macro. Saves about 150 bytes of code space. (CVS 3432) (check-in: 7e618db4 user: drh tags: trunk)
02:03
Implementation of the snippet() function for FTS1. Includes a few simple test cases but more testing is needed. (CVS 3431) (check-in: c7ee60d0 user: drh tags: trunk)
2006-09-18
21:14
Fixed a build problem in sqlite3_extension_init(). (CVS 3430) (check-in: bb2e1871 user: adamd tags: trunk)
20:24
Convert all names to lower case before sending them to the xFindFunction method of a virtual table. In FTS1, use strcmp instead of strcasecmp. Ticket #1981. (CVS 3429) (check-in: cd4e1de8 user: drh tags: trunk)
20:24
Convert all names to lower case before sending them to the xFindFunction method of a virtual table. In FTS1, use strcmp instead of strcasecmp. Ticket #1981. (CVS 3428) (check-in: efa8fb32 user: drh tags: trunk)
02:12
Modify FTS1 so that the "magic" column has the same name as the virtual table. Offsets are retrieved using a special "offsets" function whose first argument is the magic column. Snippets will ultimately be retrieved in the same way. (CVS 3427) (check-in: 5e35dc1f user: drh tags: trunk)
2006-09-16
21:45
Add the sqlite3_overload_function() API - part of the virtual table interface. (CVS 3426) (check-in: aa7728f9 user: drh tags: trunk)
