| 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 | |

| 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 | |

| 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 | |
| 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: d44d5936 user: drh tags: trunk | |
| 15:27 | Update test file func6.test so that it works with SQLITE_ENABLE_NULL_TRIM builds. check-in: e128d72f user: dan tags: trunk | |

|
2018-02-10
| ||
| 02:31 | Fix misplaced testcase() macros from the previous check-in. check-in: 3aed949a 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: fab2c2b0 user: drh tags: trunk | |
| 20:49 | Add the zorder.c extension implementing zorder() and unzorder() SQL functions. check-in: a57a77dc user: drh 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: 2a5f813b 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: 4761db83 user: dan tags: trunk | |

| 15:19 | Fix a memory leak that could follow an IO error in the zipfile extension. And add other tests. check-in: e6bb7506 user: dan tags: trunk | |
| 01:13 | When an index is based on a text representation of a numeric column in the original table, make sure the indexed value uses the canonical text representation of the numeric value in the table. Proposed fix for ticket [343634942dd54ab57b70]. check-in: 88e2ce91 user: drh tags: trunk | |

| 18:33 | If a virtual table xColumn method sets an error message using sqlite3_result_error(), use that message in preference to any error message left in the sqlite3_vtab object. check-in: 71e3b715 user: dan tags: trunk | |
| 17:43 | Add tests cases for the zipfile extension. check-in: 13b786da user: dan tags: trunk | |

| ||
| 22:41 | Fix the query planner so that it takes into account dependencies in the arguments to table-valued functions in subexpressions in the WHERE clause. Fix for ticket [80177f0c226ff54f6dd]. check-in: 7daa6873 user: drh tags: trunk | |
| 18:59 | If the argument to table function zipfile() is a blob (not text), assume that it contains a zip file image to interpret, not the name of a file on disk. check-in: 029ebcd3 user: dan tags: trunk | |

|
2018-01-24
| ||
| 20:42 | When unpacking a sorter record, do so from right to left instead of left to right, since by starting with the right-most column, the work done by OP_Column opcodes is reduced. check-in: 8055e4f4 user: drh tags: trunk | |
| 18:28 | Reorganize spellfix.c to make it easier to edit automatically (e.g. using a script). No changes to functionality. check-in: 090a64fa user: dan tags: trunk | |
| 16:04 | Rearrange fields of the BtCursor object so that it is smaller and requires less initialization, for a small performance improvement. check-in: 0ddf5292 user: drh tags: trunk | |
| 15:07 | Add the normalize.c extension. check-in: 16ebe558 user: drh tags: trunk | |

| 15:26 | Fix the modification-time setting logic in the fileio.c extension on Windows so that it works with utf8 filenames. check-in: f785b904 user: drh tags: trunk | |
| 14:01 | In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically. The only time this matters is when the file was 0 bytes in size to start with. check-in: b3122db1 user: dan tags: trunk | |
| 13:30 | Fix comment typos. No changes to code. check-in: 8e5e74c6 user: drh tags: trunk | |
