| 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. Possible fix for [787fa716be3a7f65], unless we can come up with something better. Later: Counter-example found. Closed-Leaf check-in: 8d663bfa user: drh tags: tkt787fa716-deadend | |

|
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 | Add preliminary version of "changesetfuzz" program. For fuzzing changeset data without creating corrupt changesets. check-in: 81ac8745 user: dan tags: changesetfuzz | |
| 19:37 | Add the SQLITE_DBCONFIG_DEFENSIVE flag. check-in: 11d98414 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
| ||
| 20:52 | Deploy the sqlite3Strlen30NN() function (argument guaranteed to be non-NULL) for a small performance improvement. check-in: 4a6ad519 user: drh tags: trunk | |
| 19:01 | Add support for the SQLITE_PREPARE_NORMALIZED flag and the sqlite3_normalized_sql() when compiling with SQLITE_ENABLE_NORMALIZE. Also remove unnecessary whitespace from Makefiles. check-in: 790ea39a user: drh tags: trunk | |
| 18:24 | Tweaks to the test_intarray documentation and tests. check-in: 7107f0da user: drh tags: trunk | |

|
2018-10-30
| ||
| 23:45 | Add new fuzzer cases generated by dbfuzz2. Closed-Leaf check-in: 79fdad8b user: drh tags: dbfuzz2-cases | |
| 19:14 | Update comments in sqlite3session.c to describe the format of "rebase blobs", as well as changesets and patchsets. check-in: bf93f7b5 user: dan tags: trunk | |
| 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 | |

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 | |

| 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 | |

| 20:43 | Minor code simplification. check-in: 22ae8a52 user: drh tags: trunk | |
| 20:15 | Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. check-in: 7edd26ed user: drh tags: trunk | |
