| 23:38 | Fix a build problem around sqlite3_overload_function. Only affects so/dll builds. (CVS 3435) (check-in: 791d70936b 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: 757fa22400 user: adamd tags: trunk) | |

| 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: 111ca61671 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: 7e618db457 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: c7ee60d009 user: drh tags: trunk) | |
|
2006-09-18
| ||
| 21:14 | Fixed a build problem in sqlite3_extension_init(). (CVS 3430) (check-in: bb2e1871cb 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: cd4e1de896 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: efa8fb32a5 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: 5e35dc1ffa 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: aa7728f9f5 user: drh tags: trunk) | |
|
2006-09-15
| ||
| 16:58 | Add documentation for the sqlite3_extended_result_codes() API. (CVS 3425) (check-in: a6b3f6bed2 user: drh tags: trunk) | |
| 16:09 | Fix an initialization problem in FTS1. Ticket #1977. (CVS 3424) (check-in: 5a18dd8849 user: drh tags: trunk) | |
| 12:29 | Bug fix and better testing of the extended result codes. (CVS 3423) (check-in: 78ae74db1c 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: ba579ddc43 user: drh tags: trunk) | |
|
2006-09-14
| ||
| 21:08 | New FTS1 test data based on enron emails. (CVS 3421) (check-in: 01651a32c6 user: drh tags: trunk) | |
| 18:25 | Remove file containing real email addresses. Ticket #1978. (CVS 3420) (check-in: 373a575f74 user: drh tags: trunk) | |
| 16:57 | Minor build fixes. (CVS 3419) (check-in: 3564b07c40 user: adamd tags: trunk) | |
| 13:47 | Enhanced I/O error simulation. (CVS 3418) (check-in: 86931854fc 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: f25cfa1aec 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: afd40184b7 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: f4ab546b2e 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: 607d928ce9 user: drh tags: trunk) | |
| 18:40 | Earlier refactoring changed name in fts1.c but not fts1.h. (CVS 3413) (check-in: d4edb8035c user: shess tags: trunk) | |
| 17:17 | Minor code cleanup in FTS1. (CVS 3412) (check-in: fca5928167 user: drh tags: trunk) | |
| 16:02 | Implementation of "column:" modifiers in FTS1 queries. (CVS 3411) (check-in: 820634f71e 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: adb780e0dc 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: 528036c828 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: 366a70b086 user: adamd tags: trunk) | |

| 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: 877d5558b1 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: e4fe736cfb 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: 2f5f6290c9 user: shess tags: trunk) | |
