2007-03-31
| ||
| 22:34 | Improvements to the output of the speed tests. (CVS 3785) (check-in: 1a4d8024b0 user: drh tags: trunk) | |
| 22:33 | Remove unreachable code from util.c. (CVS 3784) (check-in: 82b7a6f05c user: drh tags: trunk) | |
| 22:29 | Add the amalgamation generator to the makefile. (CVS 3783) (check-in: a0f3c960fa user: drh tags: trunk) | |
| 16:29 | Fix the amalgamation so that it can be compiled with REDEF_IO enabled. (CVS 3782) (check-in: 6a3d6142d8 user: drh tags: trunk) | |
| 15:28 | Increase test coverage by statically defining SQLITE_BIGENDIAN and related macros for ix86 platforms. Still a run-time test for other architectures. Need to add additional cases to cover other popular processors. (CVS 3781) (check-in: 476e7c3fcc user: drh tags: trunk) | |
| 15:02 | Improved test coverage for printf.c. (CVS 3780) (check-in: c2badb208f user: drh tags: trunk) | |
| 13:00 | The XFER optimization works if the target table lacks an integer primary key and is not empty as long as it has no indices. It always has and continues to work if the target table was empty. (CVS 3779) (check-in: 2c62ffcb86 user: drh tags: trunk) | |
| 03:59 | Fix a long-standing memory leak in the hash table. The leak only appears following a malloc failure of a hash that copies its keys, which rarely happens and so we have not previously noticed it. (CVS 3777) (check-in: 2aae196457 user: drh tags: trunk) | |
| 02:36 | Fix a large memory leak in the btree layer that occurs following an I/O error when in shared cache mode. (CVS 3776) (check-in: dce4cb8493 user: drh tags: trunk) | |
| 01:34 | Fix memory leaks in WHERE clause processing and in TRIGGER parsing. (CVS 3775) (check-in: 6736f4547c user: drh tags: trunk) | |
|
2007-03-30
| ||
| 20:46 | Remove vestiges of SQLITE_PROTOCOL from the test scripts. (CVS 3774) (check-in: e5e8d56397 user: drh tags: trunk) | |
| 20:43 | Remove vestiges of the SQLITE_PROTOCOL error. (CVS 3773) (check-in: 6dfd4a12a8 user: drh tags: trunk) | |
| 20:40 | Fix a memory leak that occurs after a malloc failure in trigger parsing. (CVS 3772) (check-in: 407a85e69b user: drh tags: trunk) | |
| 18:42 | Fix a memory leak in multi-database commit. Also enhance a comment that explains why a particular valgrind error is harmless. (CVS 3771) (check-in: 28c7ed1eb7 user: drh tags: trunk) | |
| 17:18 | Remove asserts on the existing of journal files in pager - asserts that are not valid for certain kinds of simulated I/O errors or for async I/O. (CVS 3769) (check-in: f5fad52a97 user: drh tags: trunk) | |
| 17:17 | Get the memleak.test script working again after recent changes. (CVS 3768) (check-in: cd6ca078e3 user: drh tags: trunk) | |
| 16:01 | Always enable exclusive access mode for TEMP databases. This cannot be changed. The locking_mode pragma has not effect on the TEMP database. (CVS 3766) (check-in: 04d3b9098e user: drh tags: trunk) | |
| 14:46 | Tease apart the two phases of pager commit. (CVS 3763) (check-in: e5f17078a2 user: drh tags: trunk) | |
| 14:06 | Refactoring the btree and pager routines into distinct two-phase commit routines. We've always done a two-phase commit - this change is just making that more apparent in the code. (CVS 3762) (check-in: 66b3ad09ea user: drh tags: trunk) | |
| 13:35 | Make yypMinor available to the stack overflow callbacks in lemon generated parsers. This does not effect SQLite. (CVS 3761) (check-in: 70c8c7e2ce user: drh tags: trunk) | |
| 13:01 | Avoid using the "clock" command in test scripts since it is a proc in Tcl8.5 and is thus not available to testfixture. (CVS 3760) (check-in: 339941d83a user: drh tags: trunk) | |
| 11:29 | Move the sqlite3_temp_directory global variable out of the OS porting layer and into main.c so that it is more accessible to non-standard OS porting layers. (CVS 3759) (check-in: 23653f7aab user: drh tags: trunk) | |
| 11:23 | Remove the anonymous union from the sqlite3_value structure since some compilers are unable to deal with it. (CVS 3758) (check-in: 6b995259bc user: drh tags: trunk) | |
| 11:12 | Comment changes in btree.c and added a missing "else" in pragma.c. (CVS 3757) (check-in: 9a7d7e3190 user: drh tags: trunk) | |
|
2007-03-29
| ||
| 20:19 | Assume any return code from fcntl() other than -1 is success. Formerly we only assumed that 0 was success. Ticket #2173. (CVS 3754) (check-in: 8d0073c0e8 user: drh tags: trunk) | |
| 20:13 | Fix to token destructors in Lemon. This does not impact SQLite. Ticket #2175. (CVS 3753) (check-in: 6195af4982 user: drh tags: trunk) | |
| 18:46 | Add the sqlite3_clear_bindings() API to the loadable extension interface. Ticket #2135. (CVS 3752) (check-in: 3111b43ec3 user: drh tags: trunk) | |
| 18:19 | Change the name of PAGER_SECTOR_SIZE to SQLITE_DEFAULT_SECTOR_SIZE. Make the new OS-layer interface routine for finding sector size optional. (CVS 3750) (check-in: 0fb9af1d6e user: drh tags: trunk) | |
| 17:57 | Make sure the strftime() date conversions put in leading zeros correctly. Ticket #2276. (CVS 3749) (check-in: e853067ec4 user: drh tags: trunk) | |
| 13:35 | Fix a bug in XFER optimization introduced by check-in (3736). (CVS 3744) (check-in: 3714ac1732 user: drh tags: trunk) | |
| 05:51 | Change BtreeMoveto so that it can be biased to the right or to the center. Use a right bias when appending and a center bias when searching. This gives about a 15% reduction in calls to sqlite3VdbeRecordCompare. (CVS 3741) (check-in: ad4a6b1a91 user: drh tags: trunk) | |
| 04:43 | Bias the b-tree binary search toward the high end. The common case is to append data and this heuristic makes append run much faster because there are fewer comparisons. (CVS 3740) (check-in: a9877f616b user: drh tags: trunk) | |
| 02:26 | Get LEMON working again when YYSTACKDEPTH is greater than zero. (CVS 3739) (check-in: e72c81dbb3 user: drh tags: trunk) | |
| 01:44 | Lemon change: compile the resulting parser with -DYYSTACKDEPTH=0 or set the "%stack_size" parameter to 0 in the grammar and the parser stack will be dynamically allocated using realloc() and free(). The default behavior is to have a finite depth stack. (CVS 3738) (check-in: 06719b741a user: drh tags: trunk) | |
| 00:08 | Patch so the the code compiles with -DSQLITE_OMIT_CHECK=1. (CVS 3737) (check-in: 72cea358da user: drh tags: trunk) | |
|
2007-03-28
| ||
| 18:04 | Improvements to the XFER Optimization of the INSERT statement. (CVS 3736) (check-in: 53fff7d1f2 user: drh tags: trunk) | |
| 14:30 | Correctly handle NULLs in IN operators. Ticket #2273. The changes in where.c and in the WhereLevel.aInLoop structure are not strictly necessary to fix this problem - they just make the code easier to read. Only the change in OP_Next/OP_Prev operator of vdbe.c is required. (CVS 3735) (check-in: 26348556d8 user: drh tags: trunk) | |
| 13:07 | Update comments in sqlite3.h. No changes to code. (CVS 3734) (check-in: 1c2656fdf6 user: drh tags: trunk) | |
| 01:59 | Fix an memory allocation error revealed by malloc3.test. (CVS 3733) (check-in: 0f7fdb022c user: drh tags: trunk) | |
|
2007-03-27
| ||
| 22:24 | The SQLITE_ENABLE_LOAD_EXTENSION macro enables the load_extension() SQL function by default without having to invoke sqlite3_enable_load_extension() first. (CVS 3732) (check-in: 113aab2cdf user: drh tags: trunk) | |
| 21:47 | Fix the prototype of the CodecAttach function in attach.c. (CVS 3731) (check-in: 902413e81b user: drh tags: trunk) | |
| 15:00 | Updates to the VACUUM documentation. Ticket #2257. (CVS 3728) (check-in: c61c97c978 user: drh tags: trunk) | |
| 14:44 | The -DSQLITE_OMIT_ATTACH=1 option now omits both the ATTACH and VACUUM commands. Ticket #2268. The regression test suite depends on both of these commands and will not run if compiled with this option. (CVS 3727) (check-in: cbebfb8960 user: drh tags: trunk) | |
| 14:05 | Fix off-by-one errors in the header comments of btree.c. Ticket #2272. (CVS 3726) (check-in: a70ea7202d user: drh tags: trunk) | |
| 13:36 | More strict aliasing fixes. The single source file library now runs successfully with -fstrict-alias. (CVS 3725) (check-in: c8a8a189a8 user: drh tags: trunk) | |
| 12:04 | Get the -DSQLITE_OMIT_XFER_OPT option working. Run speed tests on a full regression. Add the script for generating sqlite3.c. (CVS 3724) (check-in: 1dd9d0775a user: drh tags: trunk) | |
| 12:04 | Get the -DSQLITE_OMIT_XFER_OPT option working. Run speed tests on a full regression. Add the script for generating sqlite3.c. (CVS 3723) (check-in: 42c038518c user: drh tags: trunk) | |
|
2007-03-26
| ||
| 22:05 | Modify sources to that they can be combined into a single sqlite3.c source file. Eliminate all type-pruned pointer warnings. (CVS 3722) (check-in: 0b832e218e user: drh tags: trunk) | |
| 16:30 | Set the same random seed for the speed tests. (CVS 3721) (check-in: 8fe3170549 user: drh tags: trunk) | |
| 13:48 | Avoid unnecessary calls to pager_unwritelock() when in exclusive-access mode. Add the speed2.test script to the test suite. (CVS 3718) (check-in: ab53f50863 user: drh tags: trunk) | |
|
2007-03-25
| ||
| 19:08 | Add the sqlite3_prepare_v2 and sqlite3_prepare16_v2 APIs to the loadable extension interface. (CVS 3713) (check-in: f02ba56d5c user: drh tags: trunk) | |
|
2007-03-22
| ||
| 15:22 | In os_unix.c, make a distinction between pread() and pread64(). Add a new compile-time macro USE_PREAD64 to select the latter. (CVS 3709) (check-in: 177cd92910 user: drh tags: trunk) | |
|
2007-03-19
| ||
| 11:54 | Fix a comment in btree.c (CVS 3702) (check-in: 05700c11a9 user: drh tags: trunk) | |
|
2007-03-17
| ||
| 18:22 | Add documentation of the REPLACE, TRIM, LTRIM, and RTRIM functions. (CVS 3699) (check-in: d42c963620 user: drh tags: trunk) | |
| 17:52 | Added TRIM, LTRIM, and RTRIM functions. (CVS 3698) (check-in: 6fe13eeade user: drh tags: trunk) | |
| 13:27 | First cut at an implementation of the REPLACE() function. We might yet make this a compile-time option or move it into a separate source file. (CVS 3697) (check-in: c2fe746ea7 user: drh tags: trunk) | |
|
2007-03-15
| ||
| 12:51 | Fix the pager so that it handles persistent I/O errors correctly. Update the testing infrastructure so that it tests for persistent I/O errors instead of just transient errors. (CVS 3690) (check-in: ea8507a796 user: drh tags: trunk) | |
| 12:17 | Infrastructure to make simulated I/O errors persistent instead of transient. (CVS 3689) (check-in: 1a53f531ec user: drh tags: trunk) | |
| 01:16 | Enhanced temp-file security under unix. There are no known attacks against prior versions - this check-in is just an added precaution. (CVS 3687) (check-in: 5af61402f6 user: drh tags: trunk) | |
|
2007-03-13
| ||
| 16:33 | Add hyperlink anchors to the lockingv3.html document. (CVS 3685) (check-in: 3e66ea6f61 user: drh tags: trunk) | |

|
2007-03-06
| ||
| 15:53 | Fixes to the overflow-chain optization of (3672). (CVS 3674) (check-in: d6986d1e7c user: drh tags: trunk) | |
| 11:42 | Do not read the last page of a overflow chain when deleting that chain. Just add the page to the freelist. This reduces I/O. (CVS 3672) (check-in: 6db945f7a7 user: drh tags: trunk) | |
|
2007-03-04
| ||
| 13:15 | Changes to the btree and pager that reduce the amount of I/O when dealing with the freelist. (1) Avoid journaling pages of a table that is being deleted. (2) Do not read the original content of pages being pulled off of the freelist. (CVS 3671) (check-in: 2ba5be3119 user: drh tags: trunk) | |
|
2007-03-01
| ||
| 00:29 | Additional I/O Tracing support. (CVS 3667) (check-in: ed915f579a user: drh tags: trunk) | |
