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) | |
| 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) | |
| 14:04 | 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) | |
| 12:15 | 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) | |
|
2009-06-25
| ||
| 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) | |
| 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) | |
|
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) | |
| 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) | |
|
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) | |
| 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) | |
| 00:55 | Simplifications to vdbe.c in support of coverage testing. (CVS 6794) (check-in: 16680f05 user: drh 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) | |
| 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) | |

| 13:09 | Suppress some -Wextra compiler warnings from GCC. (CVS 6774) (check-in: 59ec937c user: drh 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) | |
|
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) | |
| 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) | |
|
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) | |
| 18:02 | 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) | |
| 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) | |
| 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) | |
|
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) | |
| 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) | |
| 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) | |
|
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) | |
| 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) | |
| 01:24 | Additional changes to reduce stack usage. The SQLITE_SMALL_STACK compile-time option is now available. (CVS 6708) (check-in: baea79fd user: drh tags: trunk) | |
|
2009-06-02
| ||
| 21:31 | Further reductions in the amount of stack space required. (CVS 6707) (check-in: 04bad9eb user: drh tags: trunk) | |
| 16:06 | Tweaks to vdbe.c to further reduce stack space requirements. (CVS 6706) (check-in: 6f2aab3f user: drh tags: trunk) | |
| 15:47 | Add a test case for ticket #3893 and ticket #3894. (CVS 6705) (check-in: 2472f6db 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: 7f433918 user: drh tags: trunk) | |
|
2009-06-01
| ||
| 19:53 | Avoid allocating large objects on the stack in the incremental BLOB I/O interface. (CVS 6703) (check-in: ea7dfde7 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: c7c0c58e user: drh tags: trunk) | |
