2019-02-02
21:02
Try new approach ensuring that each Schema object is only used by one connection/database at any one time. check-in: 9e8e5f52 user: dan tags: reuse-schema
2018-11-17
18:11
Fix further problems with the feature on this branch. check-in: 6d7a7e5f user: dan tags: reuse-schema1
2018-11-16

21:20
Fix some problems with the feature on this branch. Many problems remain. check-in: 31b6aee7 user: dan tags: reuse-schema1
2018-11-10
04:14
Remove a NEVER() that is reachable after all. Reverts checkin [9292d3351c40339]. Closed-Leaf check-in: c5dc7fb8 user: drh tags: read-only-shadow
03:47
Merge fixes from trunk. check-in: bf88efce user: drh tags: read-only-shadow
2018-11-09
23:45
Merge fixes from trunk. check-in: e3e9b85e user: drh tags: apple-osx
23:41
Fix invalid use of unprotected sqlite3_value objects in the sqldiff utility, when using the --changeset option. check-in: a8d65214 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
14:17
Fix for ticket [787fa716be3a7f650cac] check-in: 531eca61 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: 8d663bfa user: drh tags: tkt787fa716-deadend
2018-11-08
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: 8c74065f user: drh tags: trunk
17:32
Improved documentation for SQLITE_DBCONFIG_DEFENSIVE. Add a NEVER() macro on an unreachable branch. check-in: 9292d335 user: drh tags: read-only-shadow
2018-11-07
16:46
Performance improvement in subroutine that decides whether or not a table is read-only. check-in: 6e4968b0 user: drh tags: read-only-shadow
16:12
Merge the onefile permutation fix from trunk. check-in: e543bff8 user: drh tags: read-only-shadow
14:41
More test-case adjustments for defensive mode. check-in: 911e8a17 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: 13e21b7d user: dan tags: trunk
13:41
Merge the permutations fix from trunk. check-in: b753d849 user: drh tags: read-only-shadow
11:56
Partially revert [3e1a2f661], as some test scripts require separate $presql and $dbconfig variables. check-in: cbf85284 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: 3212733c user: drh tags: read-only-shadow
2018-11-06
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
19:37
Add the SQLITE_DBCONFIG_DEFENSIVE flag. check-in: 11d98414 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: b8d35c4a user: drh tags: trunk
13:53
Merge recent trunk enhancements. check-in: 62acf7a0 user: drh tags: apple-osx
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
2018-11-03
17:31
Correct the internal logic for SQLITE_DBCONFIG_DEFENSIVE. Closed-Leaf check-in: 76094345 user: drh tags: dbconfig-defensive
16:51
Add extra defenses against strategically corrupt databases to fts3/4. check-in: d44318f5 user: dan tags: trunk
16:09
Add the SQLITE_DBCONFIG_DEFENSIVE flag. check-in: af3f29d4 user: drh tags: dbconfig-defensive
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
