| 10:43 | In zonefile, change the "file TEXT" column back to "fileid INTEGER". The fileid can be used as a key with the associated zonefile_files table, which contains more information than just the filename. (check-in: 38d23888cf user: dan tags: zonefile) | |
| 01:48 | Remove an unreachable branch in the walIndexPage() logic. (check-in: 4e61a9731f user: drh tags: trunk) | |
| 01:05 | Small performance improvement in sqltie3WalFindFrame(). (check-in: 52013cad0e user: drh tags: trunk) | |
| 00:48 | Remove an unnecessary memset(). (check-in: e7b7f5884a user: drh tags: trunk) | |

| 22:20 | Make the walIndexPage() routine about 3x faster by factoring out the seldom used reallocation logic into a separate subroutine. (check-in: e2b107141c user: drh tags: trunk) | |
| 21:00 | Add extra code to log details when corruption is detected in the pointer-map structure maintained by the b-tree layer in begin-concurrent transactions. (check-in: 5702337160 user: dan tags: begin-concurrent-pnu) | |
| 20:57 | Update README.md in ext/zonefile. (check-in: a13b2b3813 user: dan tags: zonefile) | |
| 19:25 | Fix a problem with reading the "file" column of a zonefile virtual table. (check-in: d8d0bdcb40 user: dan tags: zonefile) | |
| 18:47 | Instead of just the frame number, store frame sizes and offsets in zonefile shadow table %_shadow_idx. (check-in: 56801c461c user: dan tags: zonefile) | |
| 17:02 | In the speed-check.sh script, make WAL mode the default. Add the --legacy option to do DELETE mode. Continue to use DELETE mode for long-term performance graphs since WAL mode was not always available, but use WAL mode for day-to-day performance measurements. (check-in: cd81613850 user: drh tags: trunk) | |
| 16:39 | Remove a superfluous "#if 1". No logic changes. (check-in: caaffd3200 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: 4bc8a48e64 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: 99eec556f0 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: c883c4d33f user: drh tags: trunk) | |
| 21:58 | Printing a value of 0 using %c terminates the string. (Closed-Leaf check-in: 255612f0a1 user: drh tags: printf-enhancement) | |
| 21:07 | Add support for invoking encryption hooks to zonefile. And mock encryption method "xor" for testing. (check-in: 55cf920c5a user: dan tags: zonefile) | |
| 20:41 | More test cases for unicode handling in printf. (check-in: ac18821111 user: drh tags: printf-enhancement) | |
| 20:23 | Test cases and a bug fix on the new unicode handling in %c. (check-in: e41d64e95b user: drh tags: printf-enhancement) | |
| 18:56 | Fix the %c substitution in printf() so that it works with unicode characters. (check-in: c35be1d9e9 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: 391540acbe 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: ca31c66304 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: 38f654dc11 user: drh tags: trunk) | |
| 16:28 | Add support for the ExtendedHeaderSize header field to zonefile. (check-in: 78267a0913 user: dan tags: zonefile) | |
| 14:27 | Modify the zonefile format in order to avoid depending on the filesize to determine the extent of the final frame. See README.md for details. (check-in: 4dbe0cba3f user: dan tags: zonefile) | |
| 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: 88258770ad user: drh tags: trunk) | |
|

| 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: 2df6bbf1b8 user: drh tags: trunk) | |
| 00:54 | Port mutex enhancments from check-in [f53b8a573b] to the Win32 implementation. (check-in: 74bb7225d1 user: mistachkin tags: trunk) | |
|

| ||
| 20:22 | Add support for "brotli" compression to the zonefile module. (check-in: 3eb25b3fa5 user: dan tags: zonefile) | |
| 19:38 | Add support for compression types "lz4" and "lz4hc" to the zonefile module. (check-in: bbe5b21ffa user: dan tags: zonefile) | |
| 18:33 | Add support for compression methods "zstd" and "zstd_global_dict". (check-in: a993a50bb8 user: dan tags: zonefile) | |
| 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: f53b8a573b user: dan tags: trunk) | |

| 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: b918d4b4e5 user: drh tags: trunk) | |
| 20:37 | Add support for zlib compression to the zonefile module. (check-in: 72b8a7ef98 user: dan tags: zonefile) | |
| 20:00 | On unix, the "PRAGMA fsync_interval=N" command causes an extra fdatasync() after writing N bytes of content, to force a write-queue flush in the underlying OS. This is an experimental hack that is not expected to land on trunk. (Leaf check-in: b18cc5fee4 user: drh tags: write-queue-flush-hack) | |
| 15:24 | Fix another point in zonefile.c so that all files are opened in either "rb" or "wb" mode. (check-in: fb1c227791 user: dan tags: zonefile) | |
| 15:17 | When calling fopen() in the zonefile extension, use modes "rb" and "wb" instead of "r" and "w". This makes no difference on unix, but is required when accessing binary files on other systems. (check-in: 4bb854ddd9 user: dan tags: zonefile) | |
| 03:56 | Improve performance of editdist3() by keeping the costs in sorted order. Also add a new regression test to editdist3(). (check-in: dc734c5b61 user: drh tags: trunk) | |
| 03:05 | Reduce the number of calls to strncmp() required to run editDist3Core(). (check-in: afd6fbc010 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: 00707f2f2f user: drh tags: trunk) | |
|

| 23:27 | Add the --readonly option to the ".open" command in the CLI. (check-in: 06870bb156 user: drh tags: trunk) | |
| 20:58 | Performance optimizations to the editdist3() function in the spellfix extension. (check-in: 70d304dcba user: drh tags: trunk) | |
| 20:25 | Disable assert() in the spellfix extension if not compiled with SQLITE_DEBUG. (check-in: 3c53ee0fde user: drh tags: trunk) | |
| 15:30 | New test cases for the editdist3() function in the spellfix extension. (check-in: 2d3f1f22d5 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: b76ec7cb58 user: drh tags: trunk) | |
|
2018-02-13
| ||
| 21:16 | Fix formatting errors in ext/zonefile/README.md. (check-in: a2221e35d6 user: dan tags: zonefile) | |
| 20:53 | Note the fact that zonefile depends on json1 in ext/zonefile/README.md. (check-in: fb27d8f6a8 user: dan tags: zonefile) | |
| 20:08 | Fix handling of maxAutoFrameSize parameter. (check-in: d65e585574 user: dan tags: zonefile) | |
| 19:13 | Improved test cases for the [f484b65f3d6230593c34f] bug. (check-in: 1f300514e6 user: drh tags: trunk) | |
| 19:01 | Enhance ext/zonefile/README.md to describe the currently available functionality. (check-in: 100137c7f6 user: dan tags: zonefile) | |
| 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: f3112e67cd user: drh tags: trunk) | |
