2009-06-18
20:52

17:22
Move codec management from database connections into the pager so that it will work together with shared cache. (CVS 6782) (check-in: ed08b53c user: drh tags: trunk)
11:34
Update the filefmt.test test script to conform to the previous check-in. (CVS 6781) (check-in: 40a40e81 user: drh tags: trunk)

2009-06-17
22:50
Avoid an assertion fault if an out-of-memory error occurs while trying to run the string-concatentation operator on a zero-blob. (This is an absurd thing to do, but even so, we still should not fault.) (CVS 6778) (check-in: 0def0b76 user: drh tags: trunk)
21:42
Fix a problem in vdbe.c that could cause a double-free of memory if the SQLITE_LIMIT_LENGTH is changed after a statement is prepared but before it is run. Also remove debugging statements from tkt3841.test. (CVS 6777) (check-in: 3d7327fd user: drh tags: trunk)
16:20
Use caution to avoid integer overflow when doing real to integer affinity operations. Ticket #3922. (CVS 6776) (check-in: 39255946 user: drh tags: trunk)
13:57
Fix a potential segfault following database corruption. Problem made visible by check-in (6772). (CVS 6775) (check-in: 69eb0ff8 user: drh tags: trunk)
13:09
Suppress some -Wextra compiler warnings from GCC. (CVS 6774) (check-in: 59ec937c user: drh tags: trunk)

11:13
Fix for #3918. Also, fix the TRACE macros in balance_nonroot(). (CVS 6772) (check-in: 368e44ec user: danielk1977 tags: trunk)
01:17
A minor simplification to the tokenizer. (CVS 6771) (check-in: 18f2076a user: drh tags: trunk)
00:35
Changes to prepare.c and callback.c to promote better test coverage. (CVS 6770) (check-in: 08cca219 user: drh tags: trunk)
2009-06-16
17:49
Changes sqlite3_prepare_v2() (and related routines) so that if it fails due to a missing table and the schema is out of date, it retries once before returning SQLITE_SCHEMA. Other changes to prepare.c to facilitate coverage testing. (CVS 6769) (check-in: 256ec3c6 user: drh tags: trunk)
16:50
Changes to balance_nonroot() and BtreeDelete() to simplify delete operations and reduce stack/heap usage while balancing b-tree structures. (CVS 6768) (check-in: 092b276e user: danielk1977 tags: trunk)
14:15
Fix a link error and warning that can occur in where.c when compiling under MSVC with SQLITE_OMIT_VIRTUALTABLE defined. Ticket #3914. (CVS 6767) (check-in: 793c93be user: shane tags: trunk)
04:35
Leave out a redundant line in build.c. Ticket #3916. (CVS 6766) (check-in: d9f997ae user: danielk1977 tags: trunk)
04:31
Remove a duplicate assert from btree.c. Ticket #3915. (CVS 6765) (check-in: d89542cd user: danielk1977 tags: trunk)
2009-06-15
23:15
Additional updates to the symbol resolver and expression tree walker to facilitate test coverage. (CVS 6764) (check-in: a49c2d4b user: drh tags: trunk)
20:45
Changes to allow a clean compile with no floating-point instructions generated when SQLITE_OMIT_FLOATING_POINT is used. (CVS 6763) (check-in: 1591b832 user: drh tags: trunk)
18:32
Updates to resolve.c to facilitate full coverage testing. (CVS 6762) (check-in: c50f0f28 user: drh tags: trunk)
16:27
Fix compiler warnings with MSVC build. (CVS 6761) (check-in: e1e64307 user: shane tags: trunk)
03:28
Version 3.6.15 (CVS 6760) (check-in: aff34826 user: drh tags: trunk, release, version-3.6.15)
00:04
Update the configuration script for version 3.6.15. (CVS 6759) (check-in: 14df65dc user: drh tags: trunk)
2009-06-14
12:47
Detect database corruption and abort balance_nonroot() before the corruption causes problems. (CVS 6758) (check-in: 3448b39d user: drh tags: trunk)
2009-06-12
17:46
Change lemon so that it does not generate yytestcase() macros on destructor cases since destructors are commonly unreachable in a reasonable grammar. For the reduce-rule switch, gather all no-ops into the "default:" case. (CVS 6757) (check-in: caebfe82 user: drh tags: trunk)
15:47
The previous check-in ((6755)) put in more yytestcase() macros than are called for. This check-in addresses that problem. (CVS 6756) (check-in: a5b182f9 user: drh tags: trunk)
13:53
The lemon parser generator now inserts yytestcase() macros on reduce action and on each destructor, to verify that all have been executed. yytestcase() is a no-op by default but can be set to something more useful inside of %include. (CVS 6755) (check-in: fe9c9177 user: drh tags: trunk)
12:50
In lemon: omit unused entries from the end of the yyFallback array. (CVS 6754) (check-in: 9cfbe2ba user: drh tags: trunk)
12:04
Enable the SQLITE_LIMIT_FUNCTION_ARG limiter. (CVS 6753) (check-in: a17e3317 user: drh tags: trunk)
11:42
Remove a C++-ism from the code. Ticket #3912. (CVS 6752) (check-in: bc729bc3 user: drh tags: trunk)
03:47
An additional memory leak in the parser fixed. Ticket #3911. (CVS 6751) (check-in: 6197b492 user: drh tags: trunk)
03:27
Make sure nested queries with USING clauses do not leak memory. Preliminary fix for ticket #3911. (CVS 6750) (check-in: bd341a10 user: drh tags: trunk)
02:27
Modifications to the parser to eliminate unreachable code. (CVS 6749) (check-in: 457e0b24 user: drh tags: trunk)
2009-06-11
17:32
Honor the SQLITE_OPEN_READONLY flag even on a :memory: or temporary database, even though such a database is pointless. Ticket #3908. (CVS 6748) (check-in: 73ba841a user: drh tags: trunk)
17:04
Add an ALWAYS() to a conditional in where.c. (CVS 6747) (check-in: 1fdb3e1e user: drh tags: trunk)
00:47
Changes to reenable codec operation and to handle memory allocation failures within a codec. (CVS 6746) (check-in: 43a6ca98 user: drh tags: trunk)
2009-06-10
19:33
Do not let the reverse_unordered_selects pragma force the use of an index that would not otherwise be used. Ticket #3904. Also: remove an test which is always true. (CVS 6745) (check-in: 78a391dc user: drh tags: trunk)
11:07
Remove a NEVER() that can sometimes occur on an OOM error. (CVS 6744) (check-in: c27f23bb user: drh tags: trunk)
09:11
Minor tweak to balance_quick() to save a few instructions. (CVS 6743) (check-in: 9ace9959 user: danielk1977 tags: trunk)
2009-06-09
19:53
Remove the actual checks that verify that memory pools (such as set up using SQLITE_CONFIG_HEAP) are 8-byte aligned. But document that 8-byte alignment is required. (CVS 6742) (check-in: e9b55ccc user: drh tags: trunk)
18:58
Fix compiler warnings with MSVC build. (CVS 6741) (check-in: 0bd84e73 user: shane tags: trunk)
