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)
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)
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)
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: 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)
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: f53b8a573b 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: b918d4b4e5 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: 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)
2018-02-14
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
19:13
Improved test cases for the [f484b65f3d6230593c34f] bug. (check-in: 1f300514e6 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: f3112e67cd user: drh tags: trunk)
16:30
Remove an unused variable from FTS4. (check-in: 27ea783b28 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: d2a81a3752 user: dan tags: trunk)
2018-02-12
20:50
Updates to the speed-check.sh script for improvements to the --vdbeprofile option. (check-in: f89c8f8ecd user: drh tags: trunk)
20:27
When compiling with VDBE_PROFILE, add the sqlite3NProfileCnt global variable which can be used to measure per-opcode values other than elapse time, if non-zero. (check-in: d44d593642 user: drh tags: trunk)
15:27
Update test file func6.test so that it works with SQLITE_ENABLE_NULL_TRIM builds. (check-in: e128d72f1a user: dan tags: trunk)
13:30
Fix a possible infinite loop in VACUUM that can come up when the schema has been carefully corrupted. Problem discovered by OSSFuzz. Test cases in TH3. (check-in: 27754b74dd user: drh tags: trunk)
2018-02-10
02:31
Fix misplaced testcase() macros from the previous check-in. (check-in: 3aed949a18 user: drh tags: trunk)
2018-02-09
23:25
Improve the performance of the built-in REPLACE() function in cases where it does many substitutions that make the string larger. OSSFuzz is reporting intermittant timeouts when running a test where it does a REPLACE() on a 930KB random blob. Perhaps this enhancement will fix that. (check-in: fab2c2b07b user: drh tags: trunk)
20:49
Add the zorder.c extension implementing zorder() and unzorder() SQL functions. (check-in: a57a77dc0c user: drh tags: trunk)
15:42
Make the tests in func6.test more robust against implementation changes. (check-in: b685d32310 user: dan tags: trunk)
15:04
Fix a harmless compiler warning. (check-in: a6c3115483 user: drh tags: trunk)
2018-02-08
01:00
Enhance sqlite3ErrStr() to include several more error codes. (check-in: ad5d3bdc73 user: mistachkin tags: trunk)
2018-02-07
18:45
Fix typo in comment. Skip tests added by check-in [4761db83b6] when running on Windows. (check-in: 468a389cdc user: mistachkin tags: trunk)
18:02
In extensions rtree, fts3 and fts5, ensure that when dynamic buffers are bound to persistent SQL statements using SQLITE_STATIC, the binding is replaced with an SQL NULL before the buffer is freed. Otherwise, a user may obtain a pointer to the persistent statement using sqlite3_next_stmt() and attempt to access the freed buffer using sqlite3_expanded_sql() or similar. (check-in: 2a5f813bc6 user: dan tags: trunk)
16:14
When the final connection disconnects from a wal mode database, check that the database file has not been moved or unlinked before deleting the wal and shm files. (check-in: 4761db83b6 user: dan tags: trunk)
2018-02-05
21:02
Adjust the previous check-in, which modified the Win32 VFS, so that it works with SQLITE_OMIT_WAL. (check-in: 36c2e67e82 user: mistachkin tags: trunk)
20:42
Allocation the mutex used by the Win32 VFS only once at initialization, instead of every time it is needed. (check-in: 535ed0ac5e user: mistachkin tags: trunk)
16:39
Allocation the mutex used by the unix VFS only once at initialization, instead of every time it is needed. (check-in: 5764dc1607 user: drh tags: trunk)
13:42
Fix another minor problem in walro2.test. (check-in: ba0631de60 user: dan tags: trunk)
13:28
Update test file walro2.test to account for systems with a page-size (getpagesize()) larger than 32KB. (check-in: d9e59cfb84 user: dan tags: trunk)
2018-02-04
20:33
In the CLI, make sure sqlite3_initialize() is called correctly even for non-UTF8 hosts. (check-in: a3591fb541 user: drh tags: trunk)
01:30
Fix harmless compiler warning seen with MSVC. (check-in: 63a914410b user: mistachkin tags: trunk)
01:29
Move variable declaration in zipfile extension to fix MSVC compiler error. (check-in: ac6a32482e user: mistachkin tags: trunk)
2018-02-02
16:28
Remove the "include <io.h>" win32 dependency from the zipfile extension. (check-in: cb3feb3bc3 user: dan tags: trunk)
16:20
Remove the time() dependency from the zipfile extension. Use SQLite VFS methods instead. (check-in: 0702fb5611 user: dan tags: trunk)
2018-02-01
20:42
Add a few more zipfile tests. No changes to code. (check-in: 3f62154587 user: dan tags: trunk)
19:41
Fix a problem triggered when a zipfile virtual table is created and written to within the same transaction. And add other zipfile tests. (check-in: 48f1c55699 user: dan tags: trunk)
15:57
New assert() statements to help ensure that no other errors similar to [343634942dd54ab57b7] ever appear in the code. (check-in: 5a70af1e9c user: drh tags: trunk)
