100 ancestors of [a7c9e898]

2005-12-08
18:12
Provide a pragma to set the codec key. (CVS 2806) check-in: a7c9e898 user: drh tags: trunk
2005-12-07
06:27
Add some tests for malloc() failure within the column_name() and column_decl() APIs. (CVS 2805) check-in: 78f10ca0 user: danielk1977 tags: trunk
2005-12-06
17:48
Allow VACUUM to detach the auxillary database after malloc() fails. (CVS 2804) check-in: 6824a78b user: danielk1977 tags: trunk
17:19
Modify ATTACH and DETACH to execute at runtime instead of compile time. (CVS 2803) check-in: 5e04ec69 user: danielk1977 tags: trunk
13:19
Report errors out of sqlite3_open16(). (CVS 2802) check-in: f5b58163 user: drh tags: trunk
12:57
Add test file for new malloc() failure handling. (CVS 2801) check-in: 0b82f962 user: danielk1977 tags: trunk
12:52
Some elements of the new malloc() failure handling. Not all cases work properly yet. Also, library is not threadsafe if malloc() fails right now. (CVS 2800) check-in: e1606658 user: danielk1977 tags: trunk
2005-12-05
22:22
Update mailing list hyperlink on the support page. (CVS 2799) check-in: 41a7aeee user: drh tags: trunk
13:20
Make sure sqlite3_result_text can handle text strings with embedded '\000' characters. (CVS 2798) check-in: 9d6057cd user: drh tags: trunk
2005-12-02
02:44
Add a test to verify that binding text with embedded '\000' works. Also comment changes in os.h. (CVS 2797) check-in: 31251a90 user: drh tags: trunk
01:57
Documentation updates. (CVS 2796) check-in: 2ffb90c3 user: drh tags: trunk
2005-11-30
03:20
Restructure the OS interface yet again. This time make the OsFile object a virtual base class which is subclassed for unix, windows, and the crash test simulator. Add the new file "os.c" for common os layer code. Move all OS-specific routines into the sqlite3Os structure. (CVS 2795) check-in: bd8740d1 user: drh tags: trunk
2005-11-29
19:56
The crash test works now, at least on unix. Untested on windows. But it never worked on windows before so if it still does not there is no big loss. I am still troubled by the current design of the OS overloading mechanism. Expect to see more changes. (CVS 2794) check-in: fa1d7ecf user: drh tags: trunk
19:50
Make the build work on windows again. Ticket #1544. (CVS 2793) check-in: 59bdca25 user: drh tags: trunk
18:37
The crash tests now compile, at least. But they get wrong results. The problem is fundamental and suggests I need to completely rethink how the new OS backend should work. (CVS 2792) check-in: 966bc68e user: drh tags: trunk
03:13
Make the OsFile structure opaque with its internal structure known only to the appropriate os_*.c implementation. Omit the os_unix.h and os_win.h include files. The crash tests are broken by this patch. (CVS 2791) check-in: 058f3175 user: drh tags: trunk
2005-11-28
12:36
Replace a call to sprintf() with sqlite3MPrintf() since on some embedded platforms, sprintf() is busted. Need to go through and do similar replacements elsewhere in the code. (CVS 2790) check-in: 1b4f2d89 user: drh tags: trunk
2005-11-26
14:24
Disable the OR-clause optimization if it does not result in an index being used that would not have been used otherwise. In other words, do not convert OR clauses into an IN statement if it does not help the optimizer. (CVS 2789) check-in: 7e7cfce0 user: drh tags: trunk
14:08
Make sure left joins still work even when the OR clause optimization fires. Ticket #1537. (CVS 2788) check-in: cbbeb9de user: drh tags: trunk
03:51
Remove some vestiges of the old OS_TEST driver. (CVS 2787) check-in: 008f676f user: drh tags: trunk
03:43
Add an OS method for making copies of file descriptors. This fixes the crash tests. (CVS 2786) check-in: 57a674fc user: drh tags: trunk
00:25
Modify the OS layer so that I/O routines are called through a virtual function table. The os_test.c module has been replaced by test6.c. The crash tests are busted now and need to be fixed. (CVS 2785) check-in: 1f69aec2 user: drh tags: trunk
2005-11-25
10:55
Ensure a low system limit on the number of open files does not cause manydb.test to fail. (CVS 2784) check-in: dba2cc0d user: danielk1977 tags: trunk
10:38
Add the compilation option SQLITE_DISABLE_DIRSYNC (CVS 2783) check-in: f9f5ecbb user: danielk1977 tags: trunk
10:38
Add the compilation option SQLITE_DISABLE_DIRSYNC (CVS 2782) check-in: f1298bb1 user: danielk1977 tags: trunk
09:01
If SQLITE_DISABLE_LFS is defined, omit the bigfile tests. (CVS 2781) check-in: f882a516 user: danielk1977 tags: trunk
08:47
Check the return code of full_fsync() when used to sync a directory fd. (CVS 2780) check-in: 84aae3b0 user: danielk1977 tags: trunk
02:43
Preserve 64-bit last insert rowids across triggers. (CVS 2779) check-in: 4dd7cfaa user: drh tags: trunk
2005-11-24
23:14
The --enable-cross-thread-connect configuration option or the -DSQLITE_ALLOW_XTHREAD_CONNECT compile-time option permits database connections to be moved across threads. This will cause latch-ups and failures on some linux systems such as RedHat-9. Do not use these options if you want a portable build. (CVS 2778) check-in: 84aa4d58 user: drh tags: trunk
22:33
Make sure sqliteInt.h is included before any system includes. This is required for QNX. Ticket #1478. (CVS 2777) check-in: ab764535 user: drh tags: trunk
22:22
Reduce the number of distinct token symbols in the parser so that the parser can store tokens in a single byte and thus be smaller in size. (CVS 2776) check-in: 2dfc9863 user: drh tags: trunk
14:34
Comment changes. No changes to code. (CVS 2775) check-in: 786e23b2 user: drh tags: trunk
14:24
Fix a comment in btree.c. No code changes. (CVS 2774) check-in: 0d8bd133 user: drh tags: trunk

12:48
Less verbose output when EXPLAIN QUERY PLAN identifies use of the primary key. (CVS 2772) check-in: 5045f099 user: drh tags: trunk
12:46
The EXPLAIN QUERY PLAN now identifies when tables use the integer primary key. (CVS 2771) check-in: 80721e2c user: drh tags: trunk

2005-11-05
15:11

2005-11-03
14:29
sqlite3_column_int() and similar routines return 0 or 0.0 on an out-of-memory condition, not some mysterious error code. (CVS 2759) check-in: 7780f5e9 user: drh tags: trunk
12:33
Prohibit parameters in CHECK constraint expressions. (CVS 2758) check-in: bb94ef64 user: drh tags: trunk

01:22
CHECK constraints that evaluate to NULL pass. (CVS 2755) check-in: 55b314a2 user: drh tags: trunk
00:41
First cut at supporting CHECK constraints. Everything appears to work, but much more testing is needed as well as documentation. (CVS 2754) check-in: 2313d912 user: drh tags: trunk
2005-11-01
15:48
Omit the SQLITE_AFF_INTEGER type affinity. All numeric values are now of type real, though an integer representation is still sometimes used internally for efficiency. (CVS 2753) check-in: e0d6f61c user: drh tags: trunk
2005-10-29
15:48

2005-10-13
02:09
Attempt to fix the SQLite core so that no floating point operations are used anywhere if SQLITE_OMIT_FLOATING_POINT is defined at compile-time. This is useful to people who use SQLite on embedded processors that lack floating point support. (CVS 2749) check-in: a0bdb584 user: drh tags: trunk
2005-10-10
00:05
Make the default TEMP_STORE=1 (TEMP tables stored on disk) in the configure script. (CVS 2748) check-in: 9753af53 user: drh tags: trunk
2005-10-06
16:53
More efficient handling of the LIMIT clause. Scalar subqueries and EXISTS on compound SELECT statements now working properly. Ticket #1473. (CVS 2747) check-in: edca8913 user: drh tags: trunk
13:59
Check-in (2744) as incomplete and broke pragma integrity_check. This completes the change and fixes the problem. (CVS 2746) check-in: 4862eaaf user: drh tags: trunk

10:40

10:29
Another attempt to get fdatasync to be ignored on non-conforming posix systems. Now a system has to opt-in for fdatasync instead of opt-out. Ticket #1467. (CVS 2741) check-in: 115340d4 user: drh tags: trunk
02:13
Add the SQLITE_OMIT_GET_TABLE compile-time flag. (CVS 2740) check-in: 6d4bc8f8 user: drh tags: trunk

2005-10-03
15:11

2005-09-25

2005-09-22
15:45
Optionally call fdatasync() instead of fsync() only if _POSIX_SYNCHRONIZED_IO is positive, which should only be the case on operating systems that actually support fdatasync(). (CVS 2732) check-in: a9b341dc user: drh tags: trunk
2005-09-20
18:13
