2007-01-26
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

2007-01-19
22:59
http://www.sqlite.org/cvstrac/tktview?tn=2166,35    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

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

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

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

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

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

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

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
