Bug fix in pragma table_info(). (CVS 3440) check-in: c037403b user: drh tags: trunk
13:09
Remove legacy cruft from shell.c. (CVS 3439) check-in: 815d8f84 user: drh tags: trunk
2006-09-23
21:44
Fix a bug in the handling of I/O errors introduced by the addition of extended error codes in check-in (3422). (CVS 3438) check-in: 20d7b294 user: drh tags: trunk
20:46
Fix documentation typo. Ticket #1986 (CVS 3437) check-in: 58c32ce3 user: drh tags: trunk
20:36
Be sure to ignore PRAGMA encoding pragmas if the encoding has already been set for a database. Ticket #1987. This patch also includes some cleanup of the schema parser and initialization logic. (CVS 3436) check-in: dc797bf4 user: drh tags: trunk
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
2006-09-15
16:58
Add documentation for the sqlite3_extended_result_codes() API. (CVS 3425) check-in: a6b3f6be user: drh tags: trunk
16:09
Fix an initialization problem in FTS1. Ticket #1977. (CVS 3424) check-in: 5a18dd88 user: drh tags: trunk
12:29
Bug fix and better testing of the extended result codes. (CVS 3423) check-in: 78ae74db user: drh tags: trunk
07:28
Add support for extended result codes - additional result information carried in the higher bits of the integer return codes. This must be enabled using the sqlite3_extended_result_code() API. Only a few extra result codes are currently defined. (CVS 3422) check-in: ba579ddc user: drh tags: trunk
2006-09-14
21:08
New FTS1 test data based on enron emails. (CVS 3421) check-in: 01651a32 user: drh tags: trunk
18:25
Remove file containing real email addresses. Ticket #1978. (CVS 3420) check-in: 373a575f user: drh tags: trunk
16:57
Minor build fixes. (CVS 3419) check-in: 3564b07c user: adamd tags: trunk
13:47
Enhanced I/O error simulation. (CVS 3418) check-in: 86931854 user: drh tags: trunk
01:17
The FTS1 tables have a new automatic column named "offset" that returns a string containing byte offset information for all matching terms. Also added a large test case based on SQLite mailing list entries. (CVS 3417) check-in: f25cfa1a user: drh tags: trunk
2006-09-13
20:22
Modify the ".dump" command in the command-line shell so that it works with virtual tables. (CVS 3416) check-in: afd40184 user: drh tags: trunk
19:21
Remove unused malloc failure test. (Ticket #1976) Also include fixes for other problems discovered while investigating ticket #1976. (CVS 3415) check-in: f4ab546b user: drh tags: trunk
19:18
In FTS1: Retain the Query structure as part of the cursor. It will be used laster as part of snippet generation. (CVS 3414) check-in: 607d928c user: drh tags: trunk
18:40
Earlier refactoring changed name in fts1.c but not fts1.h. (CVS 3413) check-in: d4edb803 user: shess tags: trunk
17:17
Minor code cleanup in FTS1. (CVS 3412) check-in: fca59281 user: drh tags: trunk
16:02
Implementation of "column:" modifiers in FTS1 queries. (CVS 3411) check-in: 820634f7 user: drh tags: trunk
15:20
Module spec parser enhancements for FTS1. Now able to cope with column names in the spec that are SQL keywords or have special characters, etc. Also added support for additional control lines. Column names can be followed by a type specifier (which is ignored.) (CVS 3410) check-in: adb780e0 user: drh tags: trunk
12:36
Fix the FTS1 test cases and add new tests. Comments added to the FTS1 code. (CVS 3409) check-in: 528036c8 user: drh tags: trunk
02:18
Allow virtual tables to contain multiple full-text-indexed columns. Added a magic column "_all" which can be used for querying all columns in a table at once.    For now, each posting list stores position/offset information for multiple columns. We may implement separate posting lists for separate columns at some future point. (CVS 3408) check-in: 366a70b0 user: adamd tags: trunk
2006-09-12
23:36
Answer queries for a particular rowid in a full-text table by looking up that rowid directly rather than by performing a table scan. (CVS 3407) check-in: 877d5558 user: adamd tags: trunk
2006-09-11
23:45
Add support for IF EXISTS on CREATE/DROP TRIGGER/VIEW. Ticket #1899. (CVS 3406) check-in: e4fe736c user: drh tags: trunk
21:39
Re-use deleted rowids for new segments. This has a somewhat surprising impact on performance, I believe because it keeps the index smaller (by keeping rowids smaller), and also because it improves locality in the table (deleting a row means we've already touched the pages leading to that rowid). (CVS 3405) check-in: 2f5f6290 user: shess tags: trunk
11:13
Get VACUUM working with virtual tables. (CVS 3404) check-in: d5ffef38 user: drh tags: trunk
00:34
Add a rudimentary tokenizer and parser to FTS1 for parsing the module arguments during initialization. Recognized arguments include a tokenizer selector and a list of virtual table columns. (CVS 3403) check-in: 227dc3fe user: drh tags: trunk
2006-09-10
17:31
Add pzErr parameters to the xConnect and xCreate methods of virtual tables in order to provide better error reporting. This is an interface change for virtual tables. Prior virtual table implementations will need to be modified and recompiled. (CVS 3402) check-in: f44b8bae user: drh tags: trunk
17:08
Add a new zErrMsg field to the sqlite3_vtab structure to support returning error messages from virtual table constructors. This change means that virtual table implementations compiled as loadable extensions for version 3.3.7 will need to be recompile for version 3.3.8 and will not be usable by both versions at one. The virtual table mechanism is still considered experimental so we feel justified in breaking backwards compatibility in this way. Additional interface changes might occurs in the future. (CVS 3401) check-in: 36693a5c user: drh tags: trunk
03:34
Add some simple test cases for the OR and NOT logic of the fts1 module. Fix lots of bugs discovered while developing these test cases. (CVS 3400) check-in: 70bcff02 user: drh tags: trunk
2006-09-09
23:11
Add support for OR and NOT terms in fts1. (CVS 3399) check-in: ae502657 user: drh tags: trunk
2006-09-08
17:00
Write doclists using a segmented technique to amortize costs better. New items for a term are merged with the term's segment 0 doclist, until that doclist exceeds CHUNK_MAX. Then the segments are merged in exponential fashion, so that segment 1 contains approximately 2*CHUNK_MAX data, segment 2 4*CHUNK_MAX, and so on. (CVS 3398) check-in: b6b93a33 user: shess tags: trunk
12:49
Add HAVE_GMTIME_R and HAVE_LOCALTIME_R flags and use them if defined. Unable to modify the configure script to test for gmtime_r and localtime_r, however, because on my SuSE 10.2 system, autoconf generates a configure script that does not work. Bummer. Ticket #1906 (CVS 3397) check-in: 862302ea user: drh tags: trunk
12:27
Bug fix in date/time computations. Ticket #1964. Some unrelated comment typos are also fixed and got accidently checked in at the same time. (CVS 3396) check-in: c81eaa0d user: drh tags: trunk
11:56
Improvements to the documentation of the return codes for sqlite3_step(). Tickets #1633, #1366, #1178, #906, and probably others too. (CVS 3395) check-in: 508248e7 user: drh tags: trunk
2006-09-06
21:39
Include io.h on Windows to quell a build warning about access() having no prototype. (CVS 3394) check-in: b3eb1732 user: adamd tags: trunk
2006-09-05
18:21
A minor change to fts1.c to fix broken build. (CVS 3393) check-in: 55a03b96 user: adamd tags: trunk
2006-09-04
18:54
Fix a bug in the new misc6.test script. Fix error messages when not compiled with memory debugging enabled. Ticket #1957. (CVS 3392) check-in: 9fb92024 user: drh tags: trunk
15:53
Make sure strings returned by sqlite3_value_text() and sqlite3_value_text16() are always '\000'-terminated. (CVS 3391) check-in: 2c63588b user: drh tags: trunk
2006-09-02
22:14
Fix bugs in test scripts so that fulltest will pass. (CVS 3390) check-in: 367bd837 user: drh tags: trunk
22:14
Changes to the Makefile.in so that MinGW users can build a DLL. Ticket #1955. (CVS 3389) check-in: 7279ddd0 user: drh tags: trunk
20:58
Add a TRACE macro to the FTS1 module for troubleshooting. Turned off by default. (CVS 3388) check-in: d4923e98 user: drh tags: trunk
20:57
Do not call the xDisconnect method on a virtual table while xUpdate is pending. Instead, defer the xDisconnect until after xUpdate completes. (CVS 3387) check-in: 61148f4c user: drh tags: trunk
14:50
Test for busted TCL builds that do not support 64-bit integers and print a warning message to users that test failures may be a result of the bad TCL build and not some problem with SQLite. Ticket #1953. (CVS 3386) check-in: ca864ee9 user: drh tags: trunk
14:17
Convert static variables into constants in the FTS module. (CVS 3385) check-in: 098cbafc user: drh tags: trunk
13:58
Automatically register the FTS module if it is compiled into the build. (CVS 3384) check-in: 8a96bdb7 user: drh tags: trunk
13:22
Construct the .def files before calling dllwrap to build the .dll files. Ticket #1951. (CVS 3383) check-in: e6e49a38 user: drh tags: trunk
00:23
Miscellaneous restructuring and cleanup based on suggestions from shess. (CVS 3382) check-in: e98b0cf2 user: adamd tags: trunk
2006-09-01
17:06
Automatically compute the sqlite3.def and tclsqlite3.def files when building windows DLLs. This will (hopefully) keep the .def files in perfect synchronization with the DLLs. Ticket #1951. (CVS 3381) check-in: 1f6d7926 user: drh tags: trunk
15:49
Remove use of the "clock" command in the test suite so that the tests will run in Tcl8.5. Ticket #1445. (CVS 3380) check-in: bedbac54 user: drh tags: trunk
00:33
Make fts1.c not rely on nul-terminated strings. Mostly a matter of making sure we always pass around ptr/len, but there were a few places where we actually relied on nul-termination.    An earlier change had additionally changed appropriate sqlite3_bind_text() calls to sqlite3_bind_blob(). I've found that this changes what's actually stored in the database, so backed those changes out. Also (and this is weird), I found that I could no longer do straight-forward = queries against %_term.term at a command-line. (CVS 3379) check-in: 5844db1a user: shess tags: trunk
00:05
Make tokenizer not rely on nul-terminated text. Instead of using strcspn() and a nul-terminated delimiter list, I just flagged delimiters in an array and wrote things inline. Submitting this for review separately because it's pretty standalone. (CVS 3378) check-in: 2631ceae user: shess tags: trunk
2006-08-31
15:07
Refactor the FTS1 module so that its name is "fts1" instead of "fulltext", so that all symbols with external linkage begin with "sqlite3Fts1", and so that all filenames begin with "fts1". (CVS 3377) check-in: e1891f0d user: drh tags: trunk
2006-08-30
21:40
Just don't run tolower() on hi-bit characters. This shouldn't cause us to break any UTF-8 code points, unless they were already broken in the input. (CVS 3376) check-in: 6c77c2d5 user: shess tags: trunk
2006-08-29
18:46
Bug fix: Get INSERT INTO ... SELECT working when the target is a virtual table. (CVS 3375) check-in: 7cdc41e7 user: drh tags: trunk
18:46
Bug fix: Get INSERT INTO ... SELECT working when the target is a virtual table. (CVS 3374) check-in: 79124857 user: drh tags: trunk
13:08
Document the fact that SQLite allows NULL values in PRIMARY KEY columns and the fact that we might design to change this in the future. Ticket #518. (CVS 3373) check-in: b99d845e user: drh tags: trunk
12:04
Improved built-in help in the command-line shell. Enable the fulltext search extension in the TCL interface. (CVS 3372) check-in: 9763b4bf user: drh tags: trunk
2006-08-28
23:46
Make static some symbols which shouldn't have been exported. (CVS 3371) check-in: 58006e38 user: shess tags: trunk
20:08
Make hi-bit characters delimiters. This is a stopgap until the tokenizer and fulltext.c recognize UTF-8 correctly. (CVS 3370) check-in: ca850d3d user: shess tags: trunk
2006-08-27
14:10
Add sqlite3_malloc and sqlite3_realloc to the sqlite3.def file. Ticket #1943. (CVS 3369) check-in: 4a74838e user: drh tags: trunk
2006-08-25
23:42
Add support for INSERT INTO ... DEFAULT VALUES. Tickets #299, #1940. (CVS 3368) check-in: bc84cb54 user: drh tags: trunk
19:20
Fix gcc gripe about parens in a ||/&& in mergePosList(). Drop unused pBlob/nBlob in index_insert_term(). Fix NULL deref in an assertion in docListUpdate() delete case. Minor code tightening in docListUpdate(). (CVS 3367) check-in: a6fcf910 user: shess tags: trunk
2006-08-24
15:18
Documentation updates for the new SQLITE_FUNCTION authorization. (CVS 3366) check-in: e029637e user: drh tags: trunk
14:59
Enhance the sqlite3_set_authorizer() callback so that it provides callbacks on each SQL function that is invoked. (CVS 3365) check-in: 4547c81f user: drh tags: trunk
