100 check-ins occurring around aff34826aa.

2009-06-24
11:08
Remove a declaration of the sqlite3Assert() function that was deleted by the previous check-in. (CVS 6810) check-in: ee20b6a2 user: drh tags: trunk
10:26
Remove the sqlite3Assert() function. The ALWAYS() and NEVER() macros call assert() directly when compiled with SQLITE_DEBUG. (CVS 6809) check-in: d8fc373f user: drh tags: trunk
05:40
Simplify things by rolling the functionality of balance_shallower() into balance_nonroot(). (CVS 6808) check-in: 11750c6a user: danielk1977 tags: trunk
2009-06-23
20:28
Enhance autoincrement so that it works with triggers that also do autoincrement inserts, even multiple inserts into the same table. Ticket #3928 (CVS 6807) check-in: 1330993d user: drh tags: trunk
16:40
Remove a condition from balance_nonroot() that is always true. (CVS 6806) check-in: c5dc80e6 user: danielk1977 tags: trunk
15:43
Call balance_shallower() from balance_nonroot() instead of from balance(). This simplifies coverage testing a bit. (CVS 6805) check-in: da9893e2 user: danielk1977 tags: trunk
14:39
Update the configure script for version 3.6.16 (CVS 6804) check-in: b614e554 user: drh tags: trunk
14:18
Update the version number in preparation for the next release. (CVS 6803) check-in: 207c4a02 user: drh tags: trunk
14:15
Simplifications to vdbe.c to promote better test coverage. (CVS 6802) check-in: 3ffc93d7 user: drh tags: trunk
11:53
Add a test to verify that #3929 is fixed. (CVS 6801) check-in: 16c1ae9b user: danielk1977 tags: trunk
11:22
Fix a failing assert in btree.c. The same bug was causing a spurious SQLITE_CORRUPT return when compiled without SQLITE_DEBUG. (CVS 6800) check-in: 47ec8749 user: danielk1977 tags: trunk
2009-06-22
19:05
Simplifications to vdbe.c and it service routines in support of coverage testing. (CVS 6799) check-in: 308f2e61 user: drh tags: trunk
18:03
Remove a condition that is always true from btree.c. (CVS 6798) check-in: 3ec8b37a user: danielk1977 tags: trunk
12:05
Make sure sqlite3BtreeCreateTable() returns an error code if the largest rootpage field is invalid in auto_vacuum mode. Update file-format comments to describe all of the "meta" values. (CVS 6797) check-in: bda38f5e user: drh tags: trunk
11:10
More simplifications to vdbe.c. Remove a NEVER() from vdbe.c that is possible after all. (CVS 6796) check-in: c8f009bd user: drh tags: trunk
05:43
If an OOM error occurs just after obtaining a shared lock on the database file, release the lock before returning. (CVS 6795) check-in: 971a9650 user: danielk1977 tags: trunk
00:55
Simplifications to vdbe.c in support of coverage testing. (CVS 6794) check-in: 16680f05 user: drh tags: trunk
2009-06-20
18:52
When recovering from the error-state in pagerSharedLock(), do not search for a hot-journal in the file-system if the pager is configured to use an anonymous temp file as the journal. (CVS 6793) check-in: 4b46805c user: danielk1977 tags: trunk
11:54
If after obtaining an exclusive lock to rollback a hot-journal file it is found that the journal file has been deleted, do not return an SQLITE_BUSY error. Just downgrade the lock and continue with the current operation. This eliminates a spurious SQLITE_BUSY error caused by a race condition. (CVS 6792) check-in: 9a066600 user: danielk1977 tags: trunk
2009-06-19
22:50
Improved documentation on the VFS methods. Ticket #3925. (CVS 6791) check-in: f66fc771 user: drh tags: trunk
22:23
Do now allow a COMMIT to occur while even a single write operating is in progress. (CVS 6790) check-in: 605520ec user: drh tags: trunk
18:32
Fix the comment on the sqlite3PExpr() subroutine. Ticket #3924. (CVS 6789) check-in: 4bb96db6 user: drh tags: trunk
17:50
If a call is made to sqlite3PagerAcquire when there are no outstanding references to any pages and the pager is in the error-state, try to exit the error-state at this point. Previously this was only attempted if the pager was configured to use exclusive mode. (CVS 6788) check-in: 62db08bc user: danielk1977 tags: trunk
16:44
Make sure group_concat() ignores initial NULL values. (CVS 6787) check-in: 90c3b23c user: drh tags: trunk
14:06
Reorganize and cleanup the prepared statement object. Remove code that has been commented out for ages and is no longer relevant to anything. (CVS 6786) check-in: 37ae5f5e user: drh tags: trunk
02:25
Fix a possible segfault when backing up an encrypted database. (CVS 6785) check-in: 7d8f178c user: drh tags: trunk
00:33
Make sure the sqlite3VdbeGetOp() subroutine works even when SQLite is compiled with SQLITE_OMIT_TRACE. (CVS 6784) check-in: 1c8ec2a6 user: drh tags: trunk
2009-06-18
20:52
Changes to the backup functionality so that it works better with codecs. (CVS 6783) check-in: 87d6796d user: drh tags: trunk
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
11:29
Reduce the minimum usable page space to 480 byte from 500 bytes. (CVS 6780) check-in: db4fb835 user: drh tags: trunk
00:41
Remove the P3 operand from OP_IsNull since it was not being used. (CVS 6779) check-in: 767ef1e4 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
11:49
Fix a bug affecting secure-delete mode introduced by (6768). (CVS 6773) check-in: a433ca82 user: danielk1977 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

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
18:14
Avoid a false failure report in the test scripts caused by the vdbe stack "compression" script. (CVS 6740) check-in: 9d332989 user: shane tags: trunk
18:02
Require that the buffer specified by SQLITE_CONFIG_HEAP be 8-byte aligned. (CVS 6739) check-in: 18b78068 user: drh tags: trunk
18:01
Changes to tokenize.c to facilitate full coverage testing. (CVS 6738) check-in: 5e8c48cf user: drh tags: trunk
15:25
Change savepoint4.test to limit database growth. Otherwise the test can take a very long time to run, depending on the prng. (CVS 6737) check-in: ed1d4f47 user: danielk1977 tags: trunk
14:27
Modify mkkeywordhash.c so that it puts the original text of each token in a comment beside the "testcase()" macros. (CVS 6736) check-in: a7d0817c user: drh tags: trunk
13:42
Enable cell overflow checking in sqlite3BtreeInitPage() using the compile-time option SQLITE_ENABLE_OVERSIZE_CELL_CHECK. Change the tests so that they recognize different error messages depending on the setting of this macro. (CVS 6735) check-in: 56bff6eb user: drh tags: trunk
11:34
Avoid calling fillInCell() to create an internal node intkey cell from balance_nonroot(). A single putVarint() does the same thing more quickly. (CVS 6734) check-in: 2e5d42ae user: danielk1977 tags: trunk
10:37
Only do the cell overread checks in sqlite3BtreeInitPage if SQLITE_OVERREAD_CHECK is defined at compile-time. (CVS 6733) check-in: 49f544eb user: drh tags: trunk
09:41
Do not clear the MemPage.nFree variable when insertCell() adds an overflow cell to a page. Not doing this means balance_quick() can avoid a call to sqlite3BtreeInitPage(). (CVS 6732) check-in: 8f1c1f61 user: danielk1977 tags: trunk
2009-06-08
19:44
Additional comments to clarify the operation of the LIKE optimizer in where.c. (CVS 6731) check-in: cc9c1217 user: drh tags: trunk
17:11
Clarification of the operation of the OR-term optimizer in where.c. (CVS 6730) check-in: 6b42dc3d user: drh tags: trunk
14:49
Change the btree balance code so that it does not call balance_nonroot() recursively. (CVS 6729) check-in: 7863db90 user: danielk1977 tags: trunk
12:52
Increase the version number to 3.6.15 in preparation for the next release. (CVS 6728) check-in: 456ea541 user: drh tags: trunk
2009-06-07
23:45
Disable the LIKE optimization if the affinity of the LHS column is not TEXT. Ticket #3901. (CVS 6727) check-in: a255c645 user: drh tags: trunk
2009-06-06
19:21
Update the error message on one of the corruption tests to account for the fact that we are finding the corruption sooner. (CVS 6726) check-in: ba9848e7 user: drh tags: trunk
16:08
Fix an error in the malloc.test test script causing a small buffer overread. (CVS 6725) check-in: 4d129bee user: danielk1977 tags: trunk
15:17
Make sure the result of sqlite3VdbeGetOp() is not used as an array following an OOM error, since after (6691) it might be a single-entry dummy opcode. (CVS 6724) check-in: 127b1398 user: drh tags: trunk
14:13
When building in debug mode with gcc, force the nullMem variable in function columnMem() to be aligned to an 8-byte boundary. Otherwise an assert() statement may fail. (CVS 6723) check-in: 3fd6c72d user: danielk1977 tags: trunk
2009-06-05
18:44
Detect when database corruption causes an attemp to set the pointer map value for a pointer map page and report the corruption. (CVS 6722) check-in: 3ae4880b user: drh tags: trunk
17:09
Remove leftover "breakpoint" commands from test scripts. Also remove blank lines at the end of scripts. (CVS 6721) check-in: 1fef16ec user: drh tags: trunk
16:46
Do not cast an unsigned int into an int for comparison. (CVS 6720) check-in: 302ab855 user: drh tags: trunk
14:17
Take care that a corrupt variable-length integer does not cause 32-bit integer overflow when parsing a record format, nor cause excessively large memory allocations. (CVS 6719) check-in: 38b20327 user: drh tags: trunk
2009-06-04
19:06
Earlier detection of freelist corruption in the page allocation routines. (CVS 6718) check-in: e557c8e5 user: drh tags: trunk
17:02
Fix an assertion fault in balance_quick() that occurs when an interior btree node has zero cells due to database corruption. Also update the corrupt7.test result vectors for a couple of cases where the error report on database corruption changed due to earlier detection. (CVS 6717) check-in: 1335e444 user: drh tags: trunk
16:14
If the root page of a btree is empty and is also not a leaf page and the page is not page 1, then report database corruption. (CVS 6716) check-in: 52b02ca5 user: drh tags: trunk
14:46
Reduce the stack usage of balance_quick(). (CVS 6715) check-in: e7ad68e9 user: danielk1977 tags: trunk
02:47
Minor updates to comments in test scripts. (CVS 6714) check-in: 453ff88f user: shane tags: trunk
02:46
Minor tweak to test script to ensure every byte in file touched at least once. (CVS 6713) check-in: bc6c2d89 user: shane tags: trunk
00:11
Fix two instances where a malformed header in a database file (in other words a corrupt database file) can lead to an assertion fault. (CVS 6712) check-in: 4e92c7f2 user: drh tags: trunk
2009-06-03
21:04
Change the pcache1.c implementation so that the "header" occurs at the end of page buffer, not at the beginning. This insures that the 20 bytes immediately following the page buffer are mapped if a read of the page buffer overruns due to a malformed cell. (CVS 6711) check-in: c54de1f5 user: drh tags: trunk
