2018-02-19
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.

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

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

2018-02-15
21:00

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: b18cc5fe 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: fb1c2277 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: 4bb854dd user: dan tags: zonefile

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

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

2018-01-30
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

2018-01-29

Add unix-only tests to check that the "unzip" program can unpack archives generated by the zipfile extension. check-in: 438c5c52 user: dan tags: trunk
18:41
Add aggregate function zipfile() to the zipfile extension. For composing new zip archives in memory. check-in: e364eeac user: dan tags: trunk
17:08
Update the omit-left-join optimization so that it works in some cases when the RHS is subject to a UNIQUE but not NOT NULL constraint. check-in: 88411a40 user: dan tags: omit-left-join-fix
16:22
Ensure the "unique-not-null" flag is set for automatic indexes on columns declared with "col UNIQUE NOT NULL" (where the NOT NULL comes after the UNIQUE). check-in: 8767f7b8 user: dan tags: trunk
2018-01-27

Fix missing header comments and other code issues in zipfile.c. check-in: 6ea8ba31 user: dan tags: trunk
16:29
If a zipfile virtual table is created with no argument - "CREATE VIRTUAL TABLE zzz USING zipfile()" - accumulate data in memory. Support "SELECT zipfile_blob(z) FROM zzz LIMIT 1" to retrieve a zip archive image. check-in: e63185ed user: dan tags: trunk
14:25
Changes to avoid a harmless UB warning from clang. check-in: 19f5c140 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
18:37
Improve text-to-integer conversion in boundary cases. The sqlite3Atoi64() function always returns the minimum or maximum integer if the magnitude of the text value is too large. Trailing whitespace is now ignored. check-in: ace0644a user: drh tags: trunk
2018-01-25
20:50
Reorganize zipfile.c code to make it easier to add support for in-memory zip archive processing. check-in: 30b92582 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

15:02
Merge changes from trunk. check-in: 6ef3de81 user: drh tags: memdb
14:40
Interchange the numeric codes for CURSOR_VALID and CURSOR_INVALID to obtain a small size decrease and performance increase. check-in: e0f192ea user: drh tags: trunk
14:39
Adjust the fts3rank.test module so that it works on big-endian systems (hopefully - I don't have a big-endian machine to test the change on.) check-in: e4766cab user: drh tags: trunk
13:15
Improved error message output when the btreeinfo.c extension is run in a connection that lacks sqlite_dbpage support. check-in: 461b0b81 user: drh tags: trunk
12:14
Prevent a harmless unused variable warning when compiling with SQLITE_OMIT_TRACE. check-in: 61a44961 user: drh tags: trunk

Fix a formatting issue in sqlite3_prepare_v3() documentation. No changes to code. check-in: 9e6066de user: drh tags: trunk
11:25
Fix the sqlite3ext.h header file so that it correctly accesses the new sqlite3_value_nochange() and sqlite3_vtab_collation() interfaces. check-in: 6185d190 user: drh tags: trunk
06:30
Update a couple of test scripts so that they work on F2FS file-systems that support atomic transactions. check-in: 49e58e64 user: dan tags: trunk
01:58
Make the shell functional even if compiled with SQLITE_OMIT_COMPLETE. Omit the sqlite3_complete() call from the fuzzing interface if it is compiled with SQLITE_OMIT_COMPLETE. check-in: c3e816cc user: drh tags: trunk
01:02
Invoke the sqlite3_complete() interface from the fuzzer. check-in: 332bf846 user: drh tags: trunk
2018-01-23
20:22
Increase the version number to 3.23.0 for the next development cycle. check-in: b58b60b2 user: drh tags: trunk
19:24
Remove an unreachable branch from sqlite3SkipAccumulatorLoad(). check-in: 8b9c8eab user: drh tags: trunk
17:33
Work around a problem with GCC on 32-bit machines that cause the CAST operator to generate a floating-point result for strings that could be represented as very large integers. check-in: 1b027319 user: drh tags: trunk
16:38
Fix a bug causing spurious "sub-select returns N columns expected 1" errors in join queries with a term like "(a, b) IN (SELECT ...)" in the WHERE clause. Ticket [7310e2fb3d046a5f5]. check-in: 14dfd96f user: dan 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
07:11
