| ||
| 16:39 | Remove a superfluous "#if 1". No logic changes. (check-in: caaffd32 user: drh tags: trunk) | |
| 15:23 | Optimize calls to sqlite3_mprintf("%z...") so that they attempt to append text onto the end of the existing memory allocation rather than reallocating and copying. (check-in: 4bc8a48e user: drh tags: trunk) | |
| 13:46 | Remove a lot of the text describing extended format options from the documentation on sqlite3_mprintf() and friends, since that information is now covered by the separate printf.html document. Provide links to that other document. No changes to code. (check-in: 99eec556 user: drh tags: trunk) | |

| 22:46 | Enhance the string formatter (used by printf()) so that the width and precision of string substitution operators refer to characters instead of bytes when the alternate-form-2 flag ("!") is used. Also fix the %c substition to always work within unicode, regardless of the alternate-form-2 flag. (check-in: c883c4d3 user: drh tags: trunk) | |
| 21:58 | Printing a value of 0 using %c terminates the string. (Closed-Leaf check-in: 255612f0 user: drh tags: printf-enhancement) | |
| 20:41 | More test cases for unicode handling in printf. (check-in: ac188211 user: drh tags: printf-enhancement) | |
| 20:23 | Test cases and a bug fix on the new unicode handling in %c. (check-in: e41d64e9 user: drh tags: printf-enhancement) | |
| 18:56 | Fix the %c substitution in printf() so that it works with unicode characters. (check-in: c35be1d9 user: drh tags: printf-enhancement) | |
| 18:03 | Make the alternate-form-2 flag ("!") change the meaning of width and precision from bytes to characters for the %q, %Q, and %w extensions of printf(). (check-in: 391540ac user: drh tags: printf-enhancement) | |
| 17:03 | In the printf() library, measure width and precision in characters rather than bytes if the "!" (alternate-form-2) flag is present on a %s or %z substitution. (check-in: ca31c663 user: drh tags: printf-enhancement) | |
| 16:34 | Only try to use the geteuid() interface on unix if HAVE_FCHOWN is defined. This fixes the build for vxWorks, we are told. (check-in: 38f654dc user: drh tags: trunk) | |
| 13:53 | Fix an assert so that it compares two CellInfo objects field by field instead of using memcmp(). Memcmp() does not work on x86 because of uninitialized padding bytes. (check-in: 88258770 user: drh tags: trunk) | |
|
2018-02-18
| ||
| 17:50 | Fix a memory leak in the processing of nested row values. This problem has existed every since row values support was added (version 3.15.0, 2016-10-14) but was only just now detected by OSSFuzz. (check-in: 2df6bbf1 user: drh tags: trunk) | |
| 00:54 | Port mutex enhancments from check-in [f53b8a573b] to the Win32 implementation. (check-in: 74bb7225 user: mistachkin tags: trunk) | |
|
2018-02-17
| ||
| 07:38 | Fix a data race causing a tsan complaint with SQLITE_ENABLE_API_ARMOR builds on unix. The race condition is not dangerous in practice, it just upsets tsan. (check-in: f53b8a57 user: dan tags: trunk) | |
|
2018-02-15
| ||
| 21:00 | Do not allow parameters or schema references inside of WITH clause of triggers and views. This fixes a bug discovered by OSSFuzz and present since common-table-expressions were first added in 2014-02-03. (check-in: b918d4b4 user: drh tags: trunk) | |
| 03:56 | Improve performance of editdist3() by keeping the costs in sorted order. Also add a new regression test to editdist3(). (check-in: dc734c5b user: drh tags: trunk) | |
| 03:05 | Reduce the number of calls to strncmp() required to run editDist3Core(). (check-in: afd6fbc0 user: drh tags: trunk) | |
| 01:03 | Fix the --heap, --pagecache, --lookaside and other options to the command-line shell that invoke sqlite3_config() so that they work again. (check-in: 00707f2f user: drh tags: trunk) | |
|
2018-02-14
| ||
| 23:27 | Add the --readonly option to the ".open" command in the CLI. (check-in: 06870bb1 user: drh tags: trunk) | |
| 20:58 | Performance optimizations to the editdist3() function in the spellfix extension. (check-in: 70d304dc user: drh tags: trunk) | |
| 20:25 | Disable assert() in the spellfix extension if not compiled with SQLITE_DEBUG. (check-in: 3c53ee0f user: drh tags: trunk) | |
| 15:30 | New test cases for the editdist3() function in the spellfix extension. (check-in: 2d3f1f22 user: drh tags: trunk) | |
| 14:13 | Try to optimize spellfix1 by storing a NULL in the k1 column of %_vocab if it would otherwise have the same value as the word column. (check-in: b76ec7cb user: drh tags: trunk) | |
|
2018-02-13
| ||
| 19:13 | Improved test cases for the [f484b65f3d6230593c34f] bug. (check-in: 1f300514 user: drh tags: trunk) | |
| 18:48 | Fix an incorrect table lookup used to find the appropriate search operator for a WHERE clause on a row-value inequality. The incorrect table lookup was causing an incorrect answer for the less-than operator. Fix for ticket [f484b65f3d6230593c34f11] (check-in: f3112e67 user: drh tags: trunk) | |
| 16:30 | Remove an unused variable from FTS4. (check-in: 27ea783b user: drh tags: trunk) | |
| 16:21 | Ensure that multiple updates of the same FTS4 row (i.e. the row with the same rowid) within a single transaction are written to separate segments. Fix for [d6ec09ec]. (check-in: d2a81a37 user: dan tags: trunk) | |
|
2018-02-12
| ||
| 20:50 | Updates to the speed-check.sh script for improvements to the --vdbeprofile option. (check-in: f89c8f8e user: drh tags: trunk) | |
