2009-07-13
09:41
Remove an assert ("assert( subpage>0 )") from btree.c that may not be true for a corrupt database. Also add comments and other assert() statements to btree.c function moveToRoot(). (CVS 6886) (check-in: 3151dab9 user: danielk1977 tags: trunk)
07:30
Remove a case from BtreeMovetoUnpacked() that is unreachable as of (6881). (CVS 6885) (check-in: 39ce2097 user: danielk1977 tags: trunk)
2009-07-12
02:32
Simplifications to btree.c to help facilitate coverage testing. (CVS 6884) (check-in: dfb146ef user: drh tags: trunk)
02:31
When an OOM fault occurs while moving a page for autovacuum in an in-memory database, be sure to undo the page move prior to returning the error, to avoid corrupting the in-memory database file. (CVS 6883) (check-in: d0964b93 user: drh tags: trunk)
2009-07-11
18:26
Remove an unused parameter from the accessPayload() function in btree.c. (CVS 6882) (check-in: 7deb6568 user: drh tags: trunk)

Unwind some complex conditions in sqlite3BtreeDelete() into separate "if" statements. (CVS 6879) (check-in: d99bde9c user: drh tags: trunk)
11:45
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)

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)
02:48
removed unused functions from test3.c (test code only); (CVS 6867) (check-in: 0eb69e8d 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)

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)
02:44
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)

2009-07-03
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)

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.
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)
