New test case that still hits an assertion fault, just to prove that the previous checkin merely made the problem more obscure and did not completely fix it. (check-in: a9a3b53264 user: drh tags: ticket-f09fcd17810f)
19:15
Simplify the query flattener so that it does not duplicate the WHERE clause of subquery that is being incorporated into the outer query - copies it directly. This is more efficient. And it also fixes the specific test case show for ticket [f09fcd17810f65f71789525] but it does not resolve the more general problem that sqlite3ExprDup() does not correctly duplicate expressions that contain subqueries with window functions.

Enhance the sqlite3_normalize_sql() interface so that it works even if the prepared statement was not initially compiled using SQLITE_PREPARE_NORMALIZED. Enhance the ".trace" command in the CLI so that it is able to access the full scope of functionality provided by sqlite3_trace_v2() and in particular so that it is able to show normalized SQL output using the newly enhanced sqlite3_normalize_sql() interface. (check-in: 7da617e97e user: drh tags: trunk)
2018-12-04
21:16

18:23
Add support for read-only shadow tables on virtual tables. Added the SQLITE_DEFAULT_DEFENSIVE compile-time option that can put SQLite in defensive mode by default. (check-in: 9c685171c4 user: drh tags: trunk)

Fix invalid use of unprotected sqlite3_value objects in the sqldiff utility, when using the --changeset option. (check-in: a8d65214a5 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: ae9638e9c0 user: dan tags: trunk)
14:17
Fix for ticket [787fa716be3a7f650cac] (check-in: 531eca6104 user: drh tags: trunk)
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: 8d663bfaaa user: drh tags: tkt787fa716-deadend)

22:53
In the treeview.c module, break out the display of SrcList into a separate subroutine, so that it can be invoked while debugging. (check-in: 8c74065f00 user: drh tags: trunk)
17:32
Improved documentation for SQLITE_DBCONFIG_DEFENSIVE. Add a NEVER() macro on an unreachable branch. (check-in: 9292d3351c user: drh tags: read-only-shadow)
14:59
Add tests and a fix for program "changesetfuzz". (check-in: 09b90db56c user: dan tags: changesetfuzz)

Update the "changesetfuzz" program to work with patchsets as well as changesets. (check-in: 75b00fbe88 user: dan tags: changesetfuzz)
16:46
Performance improvement in subroutine that decides whether or not a table is read-only. (check-in: 6e4968b005 user: drh tags: read-only-shadow)
16:12
Merge the onefile permutation fix from trunk. (check-in: e543bff87d user: drh tags: read-only-shadow)

More test-case adjustments for defensive mode. (check-in: 911e8a17a3 user: drh tags: read-only-shadow)
14:39
Fix a problem with the handling of SQLITE_FCNTL_PRAGMA in the test_onefile.c demo. (check-in: 13e21b7da8 user: dan tags: trunk)
13:41
Merge the permutations fix from trunk. (check-in: b753d849fe user: drh tags: read-only-shadow)
11:56
Partially revert [3e1a2f661], as some test scripts require separate $presql and $dbconfig variables. (check-in: cbf85284be user: dan tags: trunk)
02:17
Add the SQLITE_DEFAULT_DEFENSIVE compile-time option. Fix up test cases so that they work with DEFENSIVE enabled. (check-in: 3212733cb6 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: 141a93c843 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: a1d6c6712c user: drh tags: read-only-shadow)
15:57
Turn on defensive mode for running test scripts. Does not yet work. (check-in: 1c1d24edbb 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: d890c65825 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: f79b47c985 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: 31942b3dd3 user: drh tags: read-only-shadow)

Add the SQLITE_DBCONFIG_DEFENSIVE flag. (check-in: 11d98414ea user: drh tags: trunk)
16:38
Eponymous virtual tables appear to exist in all schemas. This is an alternative and improved fix to the eponymous virtual table in trigger problem that was previously addressed by checkin [1fa74930ab56171e]. (check-in: b8d35c4a7c user: drh tags: trunk)

Increase the version number to 3.25.3. (check-in: 1250ab8f22 user: drh tags: branch-3.25)
13:35
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: 1309c84ad3 user: drh tags: branch-3.25)
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: af39661e60 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: dcb8c73594 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: 1fa74930ab 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: 4a6ad5190b 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: 790ea39a65 user: drh tags: trunk)
18:24
Tweaks to the test_intarray documentation and tests. (check-in: 7107f0dacf user: drh tags: trunk)
01:26
Merge fixes from trunk, especially rebustness against corrupt database files. (check-in: 4b370c74ae user: drh tags: apple-osx)
01:12
Merge fuzz test cases computed by dbfuzz2. (check-in: e0d30c1862 user: drh tags: trunk)
01:04
Improved corrupt database detection in the relocatePage() routine of the b-tree module. (check-in: d57873337a user: drh tags: trunk)
2018-10-30
23:45
Add new fuzzer cases generated by dbfuzz2. (Closed-Leaf check-in: 79fdad8b42 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: bf93f7b56b 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: 4f9878107a 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: 90b2a684f7 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: 3cc01a0eaf 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: 7989bbda70 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: 5e0129ee9a user: drh tags: trunk)
00:06
Improvements to the -fsanitize=fuzzer based database file fuzzer. (Closed-Leaf check-in: 585c94db09 user: drh tags: robust-against-damaged-db)
