Remove another unreachable branch from btree.c. (CVS 6878) check-in: b0853100 user: danielk1977 tags: trunk
06:55
Modify the integrity-check code so that each b-tree page inspected is reinitialized while doing so, even if an initialized copy exists in the cache. This prevents an assert from failing when running integrity_check on a corrupt database. (CVS 6877) check-in: 709576c6 user: danielk1977 tags: trunk
05:06
Remove unreachable condition from btree.c. (CVS 6876) check-in: 47b40fef user: danielk1977 tags: trunk
2009-07-10
16:51
Fix a pager reference count leak in btree that occurs on an OOM following a database page size change. (CVS 6875) check-in: c6dfc8bd user: drh tags: trunk
09:24
Fix a double-free that can occur when using the fts3 legacy syntax '-' operator. Add tests for the same operator. Ticket #3960. (CVS 6874) check-in: c19d419e user: danielk1977 tags: trunk
02:52
Simplifications to the PRAGMA integrity_check logic in btree.c. (CVS 6873) check-in: 440c573c user: drh tags: trunk
2009-07-09
13:25
Fix two faulty assert() statements btree. (It was possible for the assertions to be false given a corrupt database file as input.) (CVS 6872) check-in: 9403f04d user: drh tags: trunk
11:36
Remove an unused branch from btree.c. (CVS 6871) check-in: 45efb78a user: danielk1977 tags: trunk
08:27
In btree.c, have setSharedCacheLock() assume that the b-tree is sharable instead of checking to see if it is. The caller has already performed this check. (CVS 6870) check-in: 3190eefd user: danielk1977 tags: trunk
05:07
Restore (btree_set_cache_size) to test3.c. This is used on unix for the tcl "crash tests". Make some functions no longer used outside of btree.c static. (CVS 6869) check-in: 1d96ce8c user: danielk1977 tags: trunk
03:20
removed the test function sqlite3BtreeFlags() (test code only); (CVS 6868) check-in: 579ba6c8 user: shane tags: trunk

2009-07-08
18:50
Fix a typo in (6861): "ifndef SQLITE_TEST" -> "ifdef SQLITE_TEST". (CVS 6865) check-in: 890dbab2 user: danielk1977 tags: trunk
18:45
Revert part of (6860) that was accidentally checked in. (CVS 6864) check-in: 11e295cc user: danielk1977 tags: trunk
18:12
Add another boundary-condition testcase() macro to btree.c. Correct the comment on modifyPagePointer(). (CVS 6863) check-in: fed66e86 user: drh tags: trunk
16:54
Improvements to comments in btree.c:freeSpace(). Added a testcase() macro to verify a boundary case is tested in sqlite3BtreeInitPage(). (CVS 6862) check-in: 5ac991b3 user: drh tags: trunk
15:14
Comment out sqlite3BtreeFlags() when not in debug mode. Tweaks to database corruption detection logic in freeSpace(). (CVS 6861) check-in: 196cbf82 user: drh tags: trunk

08:05
Remove an ALWAYS clause that could be false if an IO error within a statement executed by a virtual table caused an emergency rollback. (CVS 6859) check-in: 0cc705c2 user: danielk1977 tags: trunk
01:49
Simplifications to sqlite3BtreeInsert() and allocateSpace(). Added many testcase() macros to verify boundary conditions in btree.c. (CVS 6858) check-in: aab82a22 user: drh tags: trunk
2009-07-07
17:38
Improvements to corrupt database detection in defragmentPage(). (CVS 6857) check-in: 87bbc8d6 user: drh tags: trunk
15:47
Do not load the root-page of a b-tree table/index when opening a cursor. Instead, allow it to be loaded when the cursor is first used (in function moveToRoot()). Also move the root-page flags sanity checks that were a part of the OP_OpenRead/OpenWrite opcodes into the moveToRoot() function. (CVS 6856) check-in: 06dcfe72 user: danielk1977 tags: trunk
13:56
If an error occurs in PagerBegin(), call pager_end_transaction() to reset the internal state of the pager object. (CVS 6855) check-in: ea7ed166 user: danielk1977 tags: trunk
11:39
Fix a reference count problem following database corruption detection in the ptrmapPut() routine of btree.c. (CVS 6854) check-in: ec1e27e3 user: drh tags: trunk

Simplifications to btree.c and vdbeaux.c in support of structural coverage testing. (CVS 6853) check-in: fc2a40a9 user: drh tags: trunk
2009-07-06
21:54
Fix the pager so that it remembers the name of the journal for an in-memory database as an empty string. This is important when committing a multi-database transaction that includes one or more attached memory databases. (CVS 6852) check-in: 31a5e819 user: drh tags: trunk
19:03
Fix the backup logic so that it detects a failure to sqlite3BtreeUpdateMeta() and reports that failure back up to the top level. (CVS 6851) check-in: 471b92f2 user: drh tags: trunk
18:56
Make the sqlite3BtreeMoveto function static, since it is only used from within btree.c. Remove unused function lockBtreeWithRetry from btree.c. (CVS 6850) check-in: 30d5ec62 user: danielk1977 tags: trunk
00:44
Simplifications and comment cleanup in vdbeaux.c. (CVS 6849) check-in: 1636e783 user: drh tags: trunk
2009-07-04

2009-07-03
22:54
Remove two unused fields from the Parse structure. The TCL interface now removes leading whitespace from SQL statements before parsing them. (CVS 6846) check-in: 983cb692 user: drh tags: trunk
19:19
Remove unused code (that was commented out) from prepare.c. Remove an incorrect NEVER() macro. Fix the comment on schemaIsValid() to correctly describe its return behavior. (CVS 6845) check-in: 90deb658 user: drh tags: trunk
19:18
Cause sqlite3_exec() to return SQLITE_NOMEM if it cannot allocate memory to hold the error message for some other error. (CVS 6844) check-in: e9849292 user: drh tags: trunk
17:23
Remove an unused variable from the test code in test3.c. (CVS 6843) check-in: 9e35bec9 user: drh tags: trunk
17:09
Add a version of the Lemon parser template "lempar.c" to the src/ subfolder. This new parser template contains a couple of NEVER() macros that disable tests that are needed for general grammars but not for the specific grammar used by SQLite. SQLite builds with the modified lempar.c. (CVS 6842) check-in: d426cc64 user: drh tags: trunk
16:25
Simplify the way the read-uncommitted flag is handled to facilitate test coverage. (CVS 6841) check-in: e2112d61 user: danielk1977 tags: trunk
15:37
Make explicit the restrictions on UPDATE, DELETE, and INSERT statement syntax within triggers. Ticket #3947. (CVS 6840) check-in: c8bf40df user: drh tags: trunk
12:57
Test the result of pthread_create() and do not call pthread_join() if the thread creation failed. Ticket #3933. (CVS 6839) check-in: 304c5110 user: drh tags: trunk
2009-07-02
18:40
Fix to sqlite3AuthRead to accommodate "new" or "old" references that are used in a context where a column reference may also be used (i.e. "SELECT new. FROM <tble>"). Ticket #3944. (CVS 6838) check-in: 45fd5419 user: danielk1977 tags: trunk
17:21
When a b-tree transaction is committed when there are open cursors, downgrade shared-cache write-locks to read-locks instead of relinquishing all locks. Fix for #3942. (CVS 6837) check-in: 611e704f user: danielk1977 tags: trunk
07:47
Cause opening a transaction on a sharable b-tree module automatically obtain a read-lock on page 1. This means there is no way for sqlite3BtreeGetMeta() to fail. (CVS 6836) check-in: e3c055f1 user: danielk1977 tags: trunk
05:23
Fix for compilation with OMIT_AUTOVACUUM defined. Ticket #3940. (CVS 6835) check-in: 8f0591ae user: danielk1977 tags: trunk
2009-07-01
18:09
Change to test code and scripts allowing memsys3 to be tested using a build that has both memsys3 and memsys5 enabled. (CVS 6834) check-in: a00aeec2 user: danielk1977 tags: trunk
18:04
Fix a 1-byte buffer overwrite that can occur when a virtual table overloads an SQL function. (CVS 6833) check-in: bfe336a8 user: danielk1977 tags: trunk
16:12
Report an error if a USING or ON clause is specified following a from-list element that is not to the right of a join operator. Fix for #3846. (CVS 6832) check-in: 29b48972 user: danielk1977 tags: trunk
14:56
Do not ignore alias "a" in a query of the form "SELECT ... FROM (...) AS a" Fix for #3935. Also expand upon (6751) to fix some similar obscure memory leaks. (CVS 6831) check-in: 42f9d1e5 user: danielk1977 tags: trunk
2009-06-29
06:00
Cause incremental-blob read/write operations lock shared-cache tables in the same way as normal SQL read/writes. Add complex assert statements to make sure tehe correct shared-cache locks are held when accessing the database. Eliminate some redundant checks from btree.c. (CVS 6830) check-in: f17ef378 user: danielk1977 tags: trunk
2009-06-27
14:10
Version 3.6.16 (CVS 6829) check-in: ff691a6b user: drh tags: trunk, release
11:17
Fix an instance where sqlite3JumpHere() might be called with a negative address following an OOM fault. (CVS 6828) check-in: 49f22e55 user: drh tags: trunk
00:48
Fix a bug in sqlite3_realloc() - if called with a size of more than 2147483392 it returns 0 but it also releases the prior allocation. (CVS 6827) check-in: 653df0af user: drh tags: trunk
2009-06-26
18:35
Remove incorrect NEVER() macros from malloc.c. The allocations can be exceeded using sqlite3_malloc() and sqlite3_realloc(). (CVS 6826) check-in: 0d345e59 user: drh tags: trunk
16:32
Removed a few compiler warnings under MSVC. (CVS 6825) check-in: f01a9fc3 user: shane tags: trunk
15:14
Remove the priorNewRowid field from the sqlite3 structure. Use the last_insert_rowid as the initial value when searching for a new random rowid in the OP_NewRowid opcode. (CVS 6824) check-in: 96729b2d user: drh tags: trunk
14:17
Skip a couple tests requiring working 64bit int support on platforms without that support. Test code change only. (CVS 6823) check-in: d8c8145c user: shane tags: trunk
14:04
When sqlite3VdbeAddOp() fails due to an OOM fault, return an address of 1 rather than zero so that there appears to always be a prior instruction. This prevents a negative jump-to address computation in where.c following an OOM fault. (CVS 6822) check-in: fe02339c user: drh tags: trunk
12:30
Fix a test script problem in exclusive.test. (CVS 6821) check-in: a52ef5a4 user: danielk1977 tags: trunk
12:15
Fix the new pager.c changes so that they compile with IOTRACE defined. Fix an out-of-order variable definition in vdbeaux.c. (CVS 6820) check-in: ac145028 user: drh tags: trunk
10:39
Another change to test_journal.c to account for (6817). Again, only test code has changed. (CVS 6819) check-in: 58884b6c user: danielk1977 tags: trunk
09:01
Update test_journal.c to account for (6817). Changes to test code only. (CVS 6818) check-in: 542ee8cc user: danielk1977 tags: trunk
07:12
Avoid writing the 8-byte journal-header magic until the journal-header is synced. In persistent journal-mode, this prevents any old content that follows an unsynced journal-header from being interpreted as part of the rollback journal. (CVS 6817) check-in: a5ecffcf user: danielk1977 tags: trunk
2009-06-25
16:11
Fix a problem with a return code being ignored in insertCell(). (CVS 6816) check-in: bb5f1c01 user: danielk1977 tags: trunk
11:50
Get the notify2.test running again by removing an ALWAYS() that was mistakenly inserted and by taking care not to report corruption following an SQLITE_LOCKED failure during schema parsing. (CVS 6815) check-in: 6e9140a7 user: drh tags: trunk
09:40
Replace an "if" condition that is always true in btree.c with an assert(). (CVS 6814) check-in: daadbd9a user: danielk1977 tags: trunk
01:47
Improved handling of oversize string and blob errors. Other simplifications in support of full coverage testing. (CVS 6813) check-in: 8b340766 user: drh tags: trunk
2009-06-24
13:16
Remove an ALWAYS() macro from vdbe.c that sometimes fails on thread tests. (CVS 6812) check-in: 52eac078 user: drh tags: trunk
13:13
Disable the new malloc-37 test when locking_mode==exclusive. The test basically works, but sometimes reports "database is locked" instead of "out of memory" and that messes up the error reporting. (CVS 6811) check-in: 3b8f9dec user: drh tags: trunk
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
