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

20:04
When a table is renamed using "ALTER TABLE RENAME TO", update any REFERENCES clauses that refer to the table, unless "PRAGMA legacy_alter_table" is true and "PRAGMA foreign_keys" is set to false (i.e. so that when "PRAGMA legacy_alter_table" is set behaviour is still compatible with versions 3.24 and earlier). check-in: ae9638e9 user: dan tags: trunk
18:44
Merge latest trunk changes with this branch. check-in: ae88f8e1 user: dan tags: reuse-schema

00:02
Disable the use of coroutines for subqueries within a query that is the RHS of an IN operator, as the IN operator might be evaluated more than once.

02:17
Add the SQLITE_DEFAULT_DEFENSIVE compile-time option. Fix up test cases so that they work with DEFENSIVE enabled. check-in: 3212733c user: drh tags: read-only-shadow
2018-11-06
20:08
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
15:57
Turn on defensive mode for running test scripts. Does not yet work. check-in: 1c1d24ed user: drh tags: read-only-shadow
14:03
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
20:37
Version 3.25.3 Leaf check-in: 89e099fb user: drh tags: release, branch-3.25, version-3.25.3

07:53
Disable the IS NOT NULL optimization when the IS NOT NULL operator is part of the ON clause of a LEFT JOIN. Fix for ticket [65eb38f6e46de8c75e188a17ec]. check-in: af39661e user: drh tags: trunk

13:11
Fix a assert() in the query planner that can arise when doing row-value operations on a PRIMARY KEY that contains duplicate columns. Ticket [1a84668dcfdebaf12415d]. check-in: dcb8c735 user: drh tags: trunk
2018-11-02
17:38
Enhance triggers so that they can use table-valued-functions that exist in schemas outside of the schema in which the trigger is defined. check-in: 1fa74930 user: drh tags: trunk
2018-10-31

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

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
2018-10-25
16:58
Merge bug fixes from trunk. check-in: 1e973f65 user: drh tags: apple-osx
