| 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: 78a391dca0 user: drh tags: trunk) | |
| 11:07 | Remove a NEVER() that can sometimes occur on an OOM error. (CVS 6744) (check-in: c27f23bbaf user: drh tags: trunk) | |
| 09:11 | Minor tweak to balance_quick() to save a few instructions. (CVS 6743) (check-in: 9ace995910 user: danielk1977 tags: trunk) | |

| 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: e9b55ccc8b user: drh tags: trunk) | |
| 18:58 | Fix compiler warnings with MSVC build. (CVS 6741) (check-in: 0bd84e7387 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: 9d3329891c user: shane tags: trunk) | |
| 18:02 | Require that the buffer specified by SQLITE_CONFIG_HEAP be 8-byte aligned. (CVS 6739) (check-in: 18b78068cc user: drh tags: trunk) | |
| 18:01 | Changes to tokenize.c to facilitate full coverage testing. (CVS 6738) (check-in: 5e8c48cff7 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: ed1d4f47ee 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: a7d0817c17 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: 56bff6eb2f 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: 2e5d42aeb4 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: 49f544ebae 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: 8f1c1f61f7 user: danielk1977 tags: trunk) | |

| 17:11 | Clarification of the operation of the OR-term optimizer in where.c. (CVS 6730) (check-in: 6b42dc3d04 user: drh tags: trunk) | |
| 14:49 | Change the btree balance code so that it does not call balance_nonroot() recursively. (CVS 6729) (check-in: 7863db904d user: danielk1977 tags: trunk) | |
| 12:52 | Increase the version number to 3.6.15 in preparation for the next release. (CVS 6728) (check-in: 456ea541d6 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: a255c645c4 user: drh tags: trunk) | |
|

| 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: ba9848e7b8 user: drh tags: trunk) | |
| 16:08 | Fix an error in the malloc.test test script causing a small buffer overread. (CVS 6725) (check-in: 4d129bee69 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: 127b139819 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: 3fd6c72da5 user: danielk1977 tags: trunk) | |

| 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: 3ae4880bee 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: 1fef16ec2b user: drh tags: trunk) | |
| 16:46 | Do not cast an unsigned int into an int for comparison. (CVS 6720) (check-in: 302ab855e6 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: 38b20327a8 user: drh tags: trunk) | |
|

| 19:06 | Earlier detection of freelist corruption in the page allocation routines. (CVS 6718) (check-in: e557c8e584 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: 1335e4440f 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: 52b02ca5f3 user: drh tags: trunk) | |
| 14:46 | Reduce the stack usage of balance_quick(). (CVS 6715) (check-in: e7ad68e93b user: danielk1977 tags: trunk) | |
| 02:47 | Minor updates to comments in test scripts. (CVS 6714) (check-in: 453ff88f73 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: bc6c2d894b 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: 4e92c7f20a user: drh tags: trunk) | |
|

| 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: c54de1f540 user: drh tags: trunk) | |
| 17:26 | Add corruptD.test, a container for testing the "cell overflow" problem. Also shuffle a small amount of code in BtreeInitPage() to check that the page header pointer to the start of the cell offset array is set to a sane value. (CVS 6710) (check-in: 7fa5d3cb0f user: danielk1977 tags: trunk) | |
| 11:25 | Define a set of constants to use as the "index" argument to sqlite3BtreeGetMeta and UpdateMeta. This makes some parts of the code easier to follow. (CVS 6709) (check-in: 6dbf4eca00 user: danielk1977 tags: trunk) | |
| 01:24 | Additional changes to reduce stack usage. The SQLITE_SMALL_STACK compile-time option is now available. (CVS 6708) (check-in: baea79fd0c user: drh tags: trunk) | |
|

| 21:31 | Further reductions in the amount of stack space required. (CVS 6707) (check-in: 04bad9eb6d user: drh tags: trunk) | |
| 16:06 | Tweaks to vdbe.c to further reduce stack space requirements. (CVS 6706) (check-in: 6f2aab3f7b user: drh tags: trunk) | |
| 15:47 | Add a test case for ticket #3893 and ticket #3894. (CVS 6705) (check-in: 2472f6db95 user: drh tags: trunk) | |
| 15:21 | Add the vdbe-compress.tcl script which automatically refactors the sqlite3VdbeExec() routine to use less stack space. Use this script when constructing the amalgamation. (CVS 6704) (check-in: 7f43391831 user: drh tags: trunk) | |
|

| 19:53 | Avoid allocating large objects on the stack in the incremental BLOB I/O interface. (CVS 6703) (check-in: ea7dfde700 user: drh tags: trunk) | |
| 18:18 | Malloc for space to hold the Parse object in sqlite3_prepare() and friends. Or, if compiled with SQLITE_USE_ALLOCA, obtain space for the object from alloca(). (CVS 6702) (check-in: c7c0c58e47 user: drh tags: trunk) | |
| 17:10 | Added assert to verify winMutex system is inited before "static" mutexes are used. (CVS 6701) (check-in: b126013b5a user: shane tags: trunk) | |
| 17:06 | Ensure that "static" mutexes are deleted on shutdown so that they are not leaked across restarts. (CVS 6700) (check-in: 4e75897ee1 user: shane tags: trunk) | |
| 16:53 | Fix compiler warnings with MSVC build. (CVS 6699) (check-in: 0791588520 user: shane tags: trunk) | |
| 16:42 | Fix a couple of Windows only issues with test scripts. (CVS 6698) (check-in: 0f6bc5e1ba user: shane tags: trunk) | |
|
2009-05-31
| ||
| 21:21 | Code simplifications to facilitate coverage testing following the recent changes to the Expr object. (CVS 6697) (check-in: ee9a144d44 user: drh tags: trunk) | |
| 17:16 | Fix the ".genfkey" command of the CLI so that it does not leak memory if sqlite3_realloc() fails. Ticket #3891. (CVS 6696) (check-in: a028d69c70 user: drh tags: trunk) | |
