19:31
Fix prototypes for the parser. Syntactic change only - no effect on object code. Ticket #2193. (CVS 3607) (check-in: 02990fab user: drh tags: trunk)
19:23
Add code to select.c for printing the contents of parse-tree structures. The code is normally omitted. You must compile with -DSQLITE_TEST or -DSQLITE_DEBUG to enable it. (CVS 3606) (check-in: 1b26d687 user: drh tags: trunk)
19:04

Calling UPDATE against an fts table in a UTF-16 database inserts corrupted data into the database. The UTF-8 data is being inserted directly. This appears to happen because sqlite3_ value_text() destructively coerces a value to UTF-8, and it's never converted back when updating the table. This works around the problem by rearranging things so that the update happens before the coercion. (CVS 3596) (check-in: 4f2ab4b6 user: shess tags: trunk)

01:06
Make sure the IS NULL optimization introduced by check-in (3494) correctly handles a LEFT JOIN where the a term from the right table of the join uses an IS NULL constraint. Ticket #2177. This check-in also adds the new test cases that were suppose to have been added with (3494) but which were mistakenly omitted. (CVS 3595) (check-in: 335863e4 user: drh tags: trunk)
2007-01-16
18:19
Additional memory initialization in lemon - bug reported from wireshark. Ticket #2172. Note this problem only comes up with certain grammars, and does not impact SQLite. On the other hand, it might cause SQLite to run slower. So we might want to revisit this change at some point. (CVS 3594) (check-in: d537aa5e user: drh tags: trunk)
03:09
Make sure the parser generated by lemon always calls destructors on unused symbols, even if there is no action following the rule. Ticket #2171. (CVS 3593) (check-in: 0c5c1b93 user: drh tags: trunk)
2007-01-12
23:43
Fix a bug in sqlite3_prepare_v2() introduced by checkin (3578) and reported on the mailing list. (CVS 3592) (check-in: 87248470 user: drh tags: trunk)
23:09
Fix a bug in lemon. The code in which the error appears might well be unreachable. The changes does not effect the code that is generated for the SQLite parser. Ticket #2164. (CVS 3591) (check-in: f4ee5d83 user: drh tags: trunk)
2007-01-10
18:56

15:06
Documentation and tests to show that the cause of a parsing error is available on sqlite3_errmsg after sqlite3_step return SQLITE_SCHEMA. (CVS 3581) (check-in: 31a661d4 user: drh tags: trunk)
15:02
Updates tests and documentation to justify the behavior observed in ticket #2158. No changes to code. (CVS 3580) (check-in: e1f7cf06 user: drh tags: trunk)

14:01
When an automatic re-prepare occurs, take care not to reset the internal schema symbol table. Ticket #2156. This change also includes some debugging enhancements. (CVS 3578) (check-in: 43fe7fc1 user: drh tags: trunk)
2007-01-08
22:40
Additional tests of sqlite3_prepare_v2. (CVS 3577) (check-in: b0650aa6 user: drh tags: trunk)

14:38
Suppress compiler warnings. Fix a bug in IO error detection on windows. (CVS 3564) (check-in: daed2bab user: drh tags: trunk)
02:00
In the btree.c, when releasing the page1 lock, first make sure the pager has not reset and released the lock already. This fixes a bug introduced by (3549). (CVS 3563) (check-in: 36a2db96 user: drh tags: trunk)
01:58
Get threadtest2.c working again after being long neglected. (CVS 3562) (check-in: 06216d0d user: drh tags: trunk)
00:14
Fix a test case that changed due to (3560). Ticket #2143 (CVS 3561) (check-in: c28664d3 user: drh tags: trunk)
2007-01-04
22:13
Fix the user_version and schema_version pragmas so that they set a result column name. Ticket #2143. (CVS 3560) (check-in: f81c4227 user: drh tags: trunk)
22:13
Fix the trigger4 test so that it runs on windows. (CVS 3559) (check-in: 5e4e65ea user: drh tags: trunk)
18:01
Put a missing double-quote into the changes.html page. (CVS 3558) (check-in: 277f8faa user: drh tags: trunk)
17:01
Version 3.3.9 (CVS 3557) (check-in: 8bf19a6a user: drh tags: trunk)
16:37
Increase the version number to 3.3.9. Documentation changes prior to the release of version 3.3.9. (CVS 3556) (check-in: 7e283297 user: drh tags: trunk)
16:37
Disable the alter2.test on utf16 since the results of that test only work for utf8. (CVS 3555) (check-in: 87f350f3 user: drh tags: trunk)
14:58
Fix a memory leak introduced by the latest changes to pager.c. (CVS 3554) (check-in: 8cad5d67 user: drh tags: trunk)
14:36
Reactivate disabled "alter2" tests. (CVS 3553) (check-in: 093467a0 user: drh tags: trunk)
01:20
Fix for ticket #2141. (CVS 3552) (check-in: 70f5f3b8 user: drh tags: trunk)

Add a comment to vdbe.c to explain the use of an uninitialized variable. (CVS 3551) (check-in: 1773eb7b user: drh tags: trunk)
2007-01-03
23:37
Clean up memory leaks and uninitialized variables detected by valgrind. Identify all tests where we deliberately derefence freed memory by adding a "-misuse" tag. (CVS 3550) (check-in: 70a86270 user: drh tags: trunk)
23:36
Additional changes in the pager and os interface layers to fix problems that might be contributing to recently observed database corruption. (CVS 3549) (check-in: a593d574 user: drh tags: trunk)
15:34
Make sure that the database size cache in the pager is invalidated whenever the database is unlocked. A stale value in the database size cache can result in database corruption on a heavily loaded system running autovacuum. (CVS 3548) (check-in: 6806b9ec user: drh tags: trunk)
2007-01-02
18:41
Update the vtab_err test to check for -DSQLITE_MEMDEBUG=1 and skip the tests if missing. Pager is more careful to clear its file size cache. Remove an assert() in VDBE that might fail on a corrupt database file. (CVS 3547) (check-in: bf1afd01 user: drh tags: trunk)
2006-12-22
20:33
OS/2 change: add safeguard to be able to use SQLite loaded into high memory on OS/2 when compiled with GCC 3.3 or later. Currently, this is only used when building within the Mozilla source tree. (CVS 3546) (check-in: 720189b8 user: pweilbacher tags: trunk)
2006-12-21
22:38
Disable extension loading by default. At some point we should change the configure script to detect the presence of dlopen() automatically and add the appropriate library to the link. But that requires a working version of autoconf, which I do not have. Ticket #2124. (CVS 3545) (check-in: 87a9ee07 user: drh tags: trunk)
03:20
More fixes to the microsoft code-page nightmare... (CVS 3544) (check-in: 0b47d880 user: drh tags: trunk)

Reduce the number of utf8->unicode conversions required in wince. Ticket #2122 (CVS 3542) (check-in: 6d2ff096 user: drh tags: trunk)
01:29
Move the shared-library loading routines into the OS portability layer, thus enabling the os_win.c code to handle the character encoding confusion of win95/nt/ce. Ticket #2023. (CVS 3541) (check-in: a1bcc6de user: drh tags: trunk)
00:46
Change a parameter type from "int" to "DWORD" in the windows interface. Ticket #2122. (CVS 3540) (check-in: cca1eb3d user: drh tags: trunk)
2006-12-20
14:53
The xFilter method is not optional. (CVS 3539) (check-in: 6fdbd3bc user: drh tags: trunk)
14:31
Initialize a variable to avoid compiler warnings and human confusion. Ticket #2117. (CVS 3538) (check-in: 951af8d5 user: drh tags: trunk)
03:37
Patch to get extension loading working on wince. Ticket #2023. (CVS 3537) (check-in: a81f3ddf user: drh tags: trunk)
03:24
The query optimizer does a better job of optimizing out ORDER BY clauses that contain the rowid or which use indices that contain the rowid. Ticket #2116. (CVS 3536) (check-in: f245f5c2 user: drh tags: trunk)
02:15
Allow constraint names on DEFAULT values in a table definition. Ticket #2109. (CVS 3535) (check-in: 893d58c2 user: drh tags: trunk)
2006-12-19
18:57
Build without warnings and pass all tests with SQLITE_OMIT_LOAD_EXTENSION. Ticket #2113. (CVS 3534) (check-in: c3d118b4 user: drh tags: trunk)
18:47
Fix a typo in shell.c. Ticket #2111. (CVS 3533) (check-in: 6f8a5623 user: drh tags: trunk)
18:46
Use sqlite3_mprintf() instead of strdup() to reduce libc dependencies. Ticket #2114. (CVS 3532) (check-in: bf4a78cb user: drh tags: trunk)
2006-12-18
18:34
Speed improvement: do not journal or rollback pages that are pulled out of the freelist. (CVS 3531) (check-in: 4dffc4c3 user: drh tags: trunk)
14:12
Updates to the "Distinctive Features" document. (CVS 3530) (check-in: c734585e user: drh tags: trunk)
2006-12-16
16:25
Query optimizer enhancement: In "FROM a,b,c left join d" allow the C table to be reordered with A and B. This used to be the case but the capability was removed by (3203) and (3052) in response to ticket #1652. This change restores the capability. (CVS 3529) (check-in: 7393c81b user: drh tags: trunk)
2006-12-14
01:06
Fix a bug in lemon that leads to an assertion fault given an invalid grammar. The bug and this fix do not effect on SQLite. Ticket #2107. (CVS 3528) (check-in: f2ad230f user: drh tags: trunk)
2006-11-30
13:06
Change the table_info pragma so that it returns NULL for the default value if there is no default value. Ticket #2078. (CVS 3527) (check-in: 5f21c3a5 user: drh tags: trunk)
13:06
Improvements to the new performance tests. (CVS 3526) (check-in: 27f56c20 user: drh tags: trunk)
13:05
Fix indentation typo in btree.c. (CVS 3525) (check-in: 5d61486f user: drh tags: trunk)
2006-11-29
23:41
Drop a couple variables which are no longer used anywhere. (CVS 3524) (check-in: 08c2cc0e user: shess tags: trunk)
21:03
Test that terms longer than interior nodes work correctly. A bug prior to fts2.c r1.10 meant that such large terms caused an eventual stack overflow. (CVS 3523) (check-in: 66581162 user: shess tags: trunk)
20:53
Added the speed1.test script (CVS 3522) (check-in: 30355dfb user: drh tags: trunk)
05:17
http://www.sqlite.org/cvstrac/tktview?tn=2046

The virtual table interface allows for a cursor to field multiple xFilter() calls. For instance, if a join is done with a virtual table, there could be a call for each row which potentially matches. Unfortunately, fulltextFilter() assumes that it has a fresh cursor, and overwrites a prepared statement and a malloc'ed pointer, resulting in unfinalized statements and a memory leak.

This change hacks the code to manually clean up offending items in fulltextFilter(), emphasis on "hacks", since it's a fragile fix insofar as future additions to fulltext_cursor could continue to have the problem. (CVS 3521) (check-in: 18142fdb user: shess tags: trunk)

01:02
Delta-encode terms in interior nodes. While experiments have shown that this is of marginal utility when encoding terms resulting from regular English text, it turns out to be very useful when encoding inputs with very large terms. (CVS 3520) (check-in: c8151a99 user: shess tags: trunk)
2006-11-23
21:09
Improvements to the speed tests recently added to the test suite. (CVS 3519) (check-in: 272c1a6e user: drh tags: trunk)
11:59
Fix a typo in the OMIT_AUTORIZATION in expr.c. (CVS 3518) (check-in: 3dea7fbe user: drh tags: trunk)
11:58
Make the pager sector size configurable at compile-time. (CVS 3517) (check-in: 6221cf4f user: drh tags: trunk)
09:39
Add performance tests to the test suite. (CVS 3516) (check-in: 270c745d user: drh tags: trunk)
2006-11-20
16:21
Fix the ".dump" command in the shell. Ticket #2072. Also ticket #2065. (CVS 3515) (check-in: 9fdc2496 user: drh tags: trunk)
2006-11-18
20:20
Make sure VACUUM cleans up after itself. Ticket #2071. (CVS 3514) (check-in: 2fdc147d user: drh tags: trunk)
00:12
Store minimal terms in interior nodes. Whenever there's a break between leaf nodes, instead of storing the entire leftmost term of the rightmost child, store only that portion of the leftmost term necessary to distinguish it from the rightmost term of the leftmost child. (CVS 3513) (check-in: f6e0b080 user: shess tags: trunk)
2006-11-17
21:12
Refactoring groundwork for coming work on interior nodes. Change LeafWriter to use empty data buffer (instead of empty term) to detect an empty block. Code to validate interior nodes. Moderate revisions to leaf-node and doclist validation. Recast leafWriterStep() in terms of LeafWriterStepMerge(). (CVS 3512) (check-in: f30771d5 user: shess tags: trunk)
2006-11-13
21:09
Delta-encode docids. This is good for around 22% reduction in index size with DL_POSITIONS. It improves performance about 5%-6%. (CVS 3511) (check-in: 9b6d413d user: shess tags: trunk)
21:00
Require a minimum fanout for interior nodes. This prevents cases where excessively large terms keep the tree from finding a single root. A downside is that this could result in large interior nodes in the presence of large terms, which may be prone to fragmentation, though if the nodes were smaller that would translate into more levels in the tree, which would also have that problem. (CVS 3510) (check-in: 64b7e340 user: shess tags: trunk)
20:15
Allow backing tables to be missing on dropping fts table. Fixes http://www.sqlite.org/cvstrac/tktview?tn=1992,35 . (CVS 3509) (check-in: 9628a61a user: shess tags: trunk)
2006-11-11
01:31
The uninitialized file descriptor from the unixFile structure is passed to sqlite3DetectLockingStyle in allocateUnixFile rather than the file descriptor passed in. This was causing the locking detection on NFS file systems to behave somewhat randomly and the result was locks were not respected and data loss could occur. (CVS 3508) (check-in: b9dd16ef user: aswift tags: trunk)
2006-11-09
15:18
Update the documentation to talk about the new sqlite3_prepare_v2() API. (CVS 3507) (check-in: d9e14b61 user: drh tags: trunk)
00:24
First cut at adding the sqlite3_prepare_v2() API. Test cases added, but more testing would be useful. Still need to update the documentation. (CVS 3506) (check-in: f1efae92 user: drh tags: trunk)
