04:23
Fix a 'const' issue in trimFunc(). (CVS 4608) check-in: 64787d78 user: danielk1977 tags: trunk
2007-12-10
21:11
Make sure the windows driver responds correctly to the SQLITE_OPEN_DELETEONCLOSE flag. Ticket #2829. (CVS 4607) check-in: 19db91fd user: drh tags: trunk
18:51
Further modifications to do with ORDER BY and compound SELECT queries. Related to ticket #2822. (CVS 4606) check-in: 0d9b0e6e user: danielk1977 tags: trunk
18:07
Fix a macro in func.c that causes problems for the amalgamation. (CVS 4605) check-in: 6adbe91e user: drh tags: trunk
17:55

2007-12-08
21:10
Better resolution of ORDER BY terms in compound queries. Candidate solution for ticket #2822. Needs more testing and documentation before going final. (CVS 4602) check-in: 62a78d21 user: drh tags: trunk
18:01
Strengthen the tests for aggregate functions in GROUP BY clauses. Changes to test cases only. No changes to code. (CVS 4601) check-in: 4be8e676 user: drh tags: trunk
17:55
Fix a bug in the debugging printf logic. (CVS 4600) check-in: 1d6a9f5f user: drh tags: trunk
2007-12-07
23:47
Change prefix search from O(N*M) to O(NlogM). The previous code linearly merged the doclists, so as the accumulated list got large, things got slow (the M term, a fucntion of the number of documents in the index). This change does pairwise merges until a single doclist remains. A test search of 't*' against a database of RFC text improves from 1m16s to 4.75s. (CVS 4599) check-in: feef1b15 user: shess tags: trunk
18:55

13:26
Use the specified buffer length, not the maximum buffer length in unixFullPathname() and related functions. (CVS 4595) check-in: f015a387 user: drh tags: trunk
02:42
Continuing work on the C/C++ interface requirements that appears as comments in sqlite.h.in. (CVS 4594) check-in: 2130e712 user: drh tags: trunk
2007-12-05

2007-12-04
16:54
Make sure statement journals are initiated when doing DROP operations (since the DROP might fail after sqlite_master changes). Also make sure statement journals are initiated if there are pending SELECT statements. Ticket #2820. (CVS 4591) check-in: bf34284f user: drh tags: trunk
13:41
Fix a bug in the TCL code for sqlite3_analyzer. (CVS 4590) check-in: 7c2cf454 user: drh tags: trunk
13:22
Clarify the operation of sqlite3_blob_close() in the API documentation. Ticket #2815. (CVS 4589) check-in: 78f359df user: drh tags: trunk
2007-12-03
21:52

2007-12-02
11:46
When parsing CREATE INDEX statements from the sqlite_master table, do not search the temp database schema for the corresponding table. Only consider the database for which the schema is being parsed. Ticket #2817. (CVS 4587) check-in: e6f02aa5 user: danielk1977 tags: trunk
2007-12-01
19:25
Another fix to Makefile.in for mingw. (CVS 4586) check-in: cfaeb025 user: drh tags: trunk
19:23
Beginning attempts at casting the sqlite.h.in documentation into formal requirements. (CVS 4585) check-in: 2ea78d2c user: drh tags: trunk
09:32
Bug fix to Makefile.in to allow it to work with mingw. (CVS 4584) check-in: fdca98d1 user: drh tags: trunk

2007-11-29
18:44
Make sure we never try to "truncate" a file to a larger size. (CVS 4582) check-in: 7d2f6a1d user: drh tags: trunk
18:36
Add the optional (and experimental) mmap() memory allocator in the mem4.c module. (CVS 4581) check-in: cfd683ac user: drh tags: trunk
17:43
When using an index to scan a database table, read column data from the index in preference to the table. This increases the likelihood that the table will not be required at all. (CVS 4580) check-in: 061608c7 user: danielk1977 tags: trunk
17:05
Optimisations for expressions of the form "<value> IN (SELECT <column> FROM )". (CVS 4579) check-in: 56d0e326 user: danielk1977 tags: trunk
2007-11-28
22:36
Add the {quote: StrAccum} object for accumulating strings. Revamp xprintf to use the new object. Rewrite the group_concat() function to use the new object. Productize and test the group_concat() function. (CVS 4578) check-in: 221aee72 user: drh tags: trunk
16:19
Change the BTree so that it uses the Pagers temporary page space when reorganizing the rows on a page, rather than mallocing for space of its own. In this way, we avoid having to deal with a malloc failure deep down inside the page reorganizer. Ticket #2806 (CVS 4577) check-in: 98960132 user: drh tags: trunk
14:04
Reorganize the code for the homegrown recursive mutexes. Fix a place in the previous check-in where the #ifdef label was incorrect. Ticket #2804. (CVS 4576) check-in: 542e11f9 user: drh tags: trunk
13:55
Clarify the conditions under which homegrown recursive mutexes work (they require a coherent cache) and only enable them if there is an explicit #define so as to avoid accidental use on platforms that do not meet the constraints. Ticket #2805. (CVS 4575) check-in: 80299eeb user: drh tags: trunk
13:43
Preset the legacy_file_format pragma to the value of the primary database so that a VACUUM will not unknowingly alter the setting. Ticket #2804. (CVS 4574) check-in: f731fa6b user: drh tags: trunk
00:51
Add an implementation of recursive mutexes for unix systems that lack pthreads recursive mutexes (ex: Solaris 2.6). Modern unix systems continue to use the recursive mutexes provided by pthreads. (CVS 4573) check-in: f366a776 user: drh tags: trunk
2007-11-27
23:36
Add test cases to verify that the file format is preserved across VACUUM. Ticket #2804. (CVS 4572) check-in: 57400f50 user: drh tags: trunk
23:11
Use the hexio test utility rather than TCL's binary I/O to avoid 32/64-bit problems in io.test. Ticket #2803. (This is a change to the test harness only - not to SQLite.) (CVS 4571) check-in: 07f7dde8 user: drh tags: trunk
21:44
Remove superfluous -lpthread from publish_osx.sh. Ticket #2801. Fix a bug in mkdll.sh. (CVS 4570) check-in: 8d6e8fd3 user: drh tags: trunk

14:50
Bug fix in the configure script. Ticket #2799. The configure script is a real mess and needs to be completely rewritten. (CVS 4564) check-in: 9d15f033 user: drh tags: trunk
14:46
Update the version number to 3.5.3. Fix some minor testing problems. (CVS 4563) check-in: f4c8f2d1 user: drh tags: trunk

2007-11-26
22:54
Use macro __DARWIN__ rather than __MACOS__ for conditional compilation of MacOSX specific features. Ticket #2780. (CVS 4561) check-in: d0a4c2a3 user: drh tags: trunk
13:36
Additional out-of-memory testing. Fix bugs caused by malloc failures in where.c. Tickets #2794, #2795, #2796, and #2797. (CVS 4560) check-in: 5e02dbab user: drh tags: trunk
2007-11-24

00:41
The FTS3 amalgamation can now be appended to the SQLite amalgamation to generate a single source file that contains both components. (CVS 4558) check-in: 0fc61f99 user: drh tags: trunk
2007-11-23
18:19
Fix a typo in a change to all.test from earlier today. (CVS 4557) check-in: 8c0b2157 user: drh tags: trunk

15:02
Make sure that INSERT INTO ... SELECT ... always uses an ephemeral intermediate table if the SELECT clause refers to the destination table, even if the SELECT clause is compound or uses the destination table in a subquery. This fixes a long-standing bug that can cause an infinite loop for some SQL statements. (CVS 4552) check-in: 492b39b6 user: drh tags: trunk
13:42

15:40
Fix a code comment in select.c. No code changes. (CVS 4539) check-in: cf41d6a0 user: danielk1977 tags: trunk
15:29
Where possible, transform the DISTINCT qualifier to a GROUP BY clause. GROUP BY clauses may be optimized by indices, DISTINCT qualifiers cannot. (CVS 4538) check-in: e5633123 user: danielk1977 tags: trunk
09:50
