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)

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)
03:56
Improve performance of editdist3() by keeping the costs in sorted order. Also add a new regression test to editdist3(). (check-in: dc734c5b 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)

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)

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)

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)

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

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)

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)

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)

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)

Fix main.mk so that testfixture can be built either from the amalgamation or from individual source files. No changes to code. (check-in: a8aea925 user: dan tags: trunk)
13:15
Fix harmless compiler warnings, mostly unused parameters for UDFs in the CLI. (check-in: bfbeffab user: drh tags: trunk)

Do not attempt to use pragma_module_list in the command-line shell unless it has been compiled with -DSQLITE_INTROSPECTION_PRAGMAS. (check-in: 39ca5fcd user: drh tags: trunk)
00:04
The ".schema" command in the command-line shell now shows the structure of table-valued functions and eponymous virtual tables if they are named on the ".schema" command line. Example: ".schema sql%" shows the structure of the "sqlite_dbstat" and "sqlite_stmt" virtual tables. (check-in: f80f6651 user: drh tags: trunk)

Improved name quoting and escaping in the auxiliary column info section of the ".schema" output for views and virtual tables. (check-in: d64b14e3 user: drh tags: trunk)
21:28
In the output of ".schema", show the column names of virtual tables and views in a separate comment. (check-in: 2234a87f user: drh tags: trunk)

Minor simplification to the ".schema" logic in the command-line shell. (check-in: add45c47 user: drh tags: trunk)

Add support for the sqlite_unsupported_offset() SQL function if and only if compiled using -DSQLITE_ENABLE_OFFSET_SQL_FUNC. Use that definition when compiling the command-line shell. (check-in: 4f1f1f52 user: drh tags: trunk)
16:37
Stricter test cases. (Closed-Leaf check-in: 9406c0a6 user: drh tags: location-function)
15:19
Fix a typo in the MSVC makefile. (check-in: 89e5720a user: drh tags: location-function)
15:04
Change the function name to sqlite_unsupported_offset(X). Only enable the function if compiled with -DSQLITE_ENABLE_OFFSET_SQL_FUNC. The makefiles add that definition to shell builds. (check-in: 7a7f826e user: drh tags: location-function)
14:33
Enhance location(X) so that it works with indexes and WITHOUT ROWID tables. The function might return an offset to the main table or to an index, depending on whether the column X would be loaded from the main table or from the index. (check-in: dd94d6a8 user: drh tags: location-function)
13:35
Merge recent enhancements from trunk. (check-in: 6251e438 user: drh tags: location-function)
12:50
Add test cases for the undocumented behavior of duplicate columns on an INSERT or UPDATE. (check-in: f4349c0c user: drh tags: trunk)

The output of sqlite3_trace() now shows each command of a trigger as it is evaluated. This feature involved major changes to the parser, such as removing the ExprSpan object and replacing it with a new mechanism for capturing the original SQL text of phrases in the input SQL. (check-in: 0fdf97ef user: drh tags: trunk)
21:30
Omit all sqlite3_trace() output from the triggers associated with foreign key constraints. (Closed-Leaf check-in: fda08e3d user: drh tags: span-refactor)
