36 check-ins using file src/vacuum.c version b620ffff

2007-01-03
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)
02:21
Use GetProcAddressA() on wince. Ticket #2123 (CVS 3543) (check-in: e3dddd1c user: drh tags: trunk)
01:37
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)

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)
