33 check-ins using file www/lang.tcl version 529f5f0f

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)
