2018-01-29
19:47
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

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)

14:25
Changes to avoid a harmless UB warning from clang. (check-in: 19f5c140 user: drh tags: trunk)

2018-01-26
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)
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)
01:20
Slightly smaller and faster implementation of OP_If and OP_IfNot. (check-in: 6ab42934 user: drh 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)
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)
11:29
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)
