13:56
Enhance the xBestIndex interface of virtual table so that if the xBestIndex method returns SQLITE_CONSTRAINT then that particular combination of constraints is considered unusable and does not participate further in query planning. (check-in: 684013ce user: drh tags: trunk)

Update the changesetfuzz program to fuzz changeset schemas as well as data. (check-in: 141a93c8 user: dan tags: changesetfuzz)
19:26
Enable DEFENSIVE mode by default for tests. This requires lots of case of turning DEFENSIVE off in order to dodgy things to the database for testing purposes. No all of those cases are yet handled, so "make test" does not run to completion. (check-in: a1d6c671 user: drh tags: read-only-shadow)

Only allow shadow table to be written from within a recursive SQL call. Omit the SQLITE_PREPARE_SHADOW flag. Some tests are failing because the tests depend on being able to write to shadow tables. (check-in: d890c658 user: drh tags: read-only-shadow)
13:37
Add enforcement of read-only on shadow tables. This does not currently work since some virtual tables are attempting to update shadow tables using sqlite3_exec(). (check-in: f79b47c9 user: drh tags: read-only-shadow)
2018-11-05
23:01
Initial code to make shadow tables read-only to ordinary SQL. The now xShadowName method is added to the sqlite3_module object and is used to identify potential shadow tables. The SQLITE_PREPARE_SHADOW argument to sqlite3_prepare_v3() is defined. It is designed to permit writing to shadow tables, but is currently an unused placeholder. (check-in: 31942b3d user: drh tags: read-only-shadow)

16:25
Split the SQLITE_WriteSchema flag in two flags, WriteSchema and SQLITE_NoSchemaError. Set only WriteSchema on a VACUUM to avoid problems when trying to vacuum a corrupt database. With this change, the size of the flags field on sqlite3 must grow from 32 to 64 bytes. (check-in: 4f987810 user: drh tags: trunk)
15:31
Modify the CLI so that the --deserialize option is only available if it is compiled with SQLITE_ENABLE_DESERIALIZE. DESERIALIZE is now off by default for the main.mk makefile, but on for Makefile.in and Makefile.msc. (check-in: 90b2a684 user: drh tags: trunk)
15:20
Improvements to the -fsanitize=fuzzer based database file fuzzer. (Cherrypick from the rubust-against-damaged-db branch.) (check-in: 3cc01a0e user: drh tags: trunk)
14:36
In the CLI, when opening a file that begins with the normal SQLite prefix, open the file as a normal database even if it has a ZIP for AppendVFS record at the end. (check-in: 7989bbda user: drh tags: trunk)
13:19
Enable sqlite3_deserialize() in the CLI. The --deserialize option associated with opening a new database cause the database file to be read into memory and accessed using the sqlite3_deserialize() API. This simplifies running tests on a database without risk of modifying the file on disk. (check-in: 5e0129ee user: drh tags: trunk)
00:06
Improvements to the -fsanitize=fuzzer based database file fuzzer. (Closed-Leaf check-in: 585c94db user: drh tags: robust-against-damaged-db)

Initial code for a fuzzing tool on database file that works with the -fsanitize=fuzzer option of clang. (check-in: 90d12094 user: drh tags: trunk)
2018-10-26
17:05
Add the sqlite3session_config() interface. For configuring global parameters belonging to the sessions module. (check-in: 1e69f3ff user: dan tags: trunk)
15:36
Prevent an == constraint specified using the table-valued-function argument syntax from being used to optimize any scan not related to the virtual table for which it was specified as an argument. (check-in: 4d46685f user: dan tags: trunk)

11:55
Speed up xAccess() calls made on an RBU VFS when there are lots of open connections. Cherrypick of [310b4b65]. (check-in: fda8fdb0 user: dan tags: branch-3.22)

Merge enhancements from trunk. (check-in: 9e10d88b user: drh tags: apple-osx)
13:51
On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. (check-in: 90cf32cd user: drh tags: trunk)
10:37
In the CLI, fix a file descriptor leak following OOM and a missing va_end() call. (check-in: ec36d15a user: drh tags: trunk)

20:04
Fix an issue with the new memstat.c extension. (check-in: ce6e80b1 user: drh tags: trunk)
18:58
Merge latest trunk changes into this branch. (check-in: 2ac72114 user: dan tags: reuse-schema)
18:55
Replace the new geopoly_reverse() function with geopoly_ccw(). The geopoly_ccw() function only reverses the vertex order if doing so is necessary to get the correct right-hand winding rule on the polygon. (check-in: 07506694 user: drh tags: trunk)
12:58
Add the geopoly_reverse() function to the GeoPoly extension. (check-in: 690dd18a user: drh tags: trunk)

14:38
Fix the ".help -all" option in the command-line shell. (check-in: aac8f1df user: drh tags: trunk)
14:33
Ensure each ALTER TABLE statement makes just a single SQLITE_ALTER_TABLE call to the authorizer function. (Leaf check-in: dac28547 user: dan tags: alter-auth-callbacks)
13:46
Add test cases and assert() statements to ensure that the authorizer is being called as expected from within ALTER TABLE. (check-in: ff10d2c7 user: dan tags: trunk)
2018-10-05
20:09
When the left-hand side of a WHERE clause contraint is a UNIQUE column, and that term of the WHERE clause is not used for indexing, assume that the term reduces the number of output rows by half. This is one proposed fix for ticket [e8b674241947eb3ba4] (Leaf check-in: 5c243eec user: drh tags: unique-constraint-weights)

The 0x8000 optimization flag associated with SQLITE_TESTCTRL_OPTIMIZATIONS causes a large penalty (200) to be added to all sorting costs, which encourages the query planner avoid using the sorter. This flag can be used in experiments to help come up with a more accurate estimate of the true cost of sorting. (Leaf check-in: 857a1b01 user: drh tags: query-planner-debug)
2018-10-03
