2019-02-14Fixed #30171 -- Fixed DatabaseError in servers tests.Jon Dufresne
Made DatabaseWrapper thread sharing logic reentrant. Used a reference counting like scheme to allow nested uses. The error appeared after 8c775391b78b2a4a2b57c5e89ed4888f36aada4b.

Partially reverted 50b8493581fea3d7137dd8db33bac7008868d23a (refs #29654) to avoid a crash when the user shell doesn't support non-ASCII characters.

2018-12-22Fixed #30054 -- Implemented cascaded flush on SQLite.Simon Charette
This is required to maintain foreign key integrity when using TransactionTestCase.available_apps. Refs #30033, #14204, #20483.

2018-12-22Refs #30033 -- Checked constraints before committing SQLite schema changes.Simon Charette
This order of operations is more in line with SQLite's documented table rebuild procedure and ensures that changes aren't committed if foreign key integrity is broken.

2018-12-17Fixed #29928 -- Enabled deferred constraint checks on SQLite 3.20+.Simon Charette
Refs #11665, #14204. Thanks Michel Samia for the report.
2018-12-17Refs #29182 -- Stopped relying on legacy alter table semantic on SQLite 3.26+.Simon Charette
SQLite 3.26 changed the behavior of table and column renaming operations to repoint foreign key references even if foreign key checks are disabled. This makes the workarounds in place to simulate this behavior unnecessary on SQLite 3.26+. Refs #30033.
2018-12-17Fixed #30033 -- Conformed to the recommended table alterations procedure on ↵Simon Charette
SQlite3. Refs #29182. The previous implementation was following a procedure explicitly documented as incorrect and was the origin of the breakage experienced on SQLite 3.26 release that were addressed by c8ffdbe514b55ff5c9a2b8cb8bbdf2d3978c188f. Thanks to Richard Hipp for pointing out the usage of the incorrect procedure.
2018-12-17Refs #29928 -- Implemented fast constraint checking on SQLite 3.20+.Simon Charette
2018-12-15Fixed #30023 -- Prevented SQLite schema alterations while foreign key checks ↵Simon Charette
are enabled. Prior to this change foreign key constraint references could be left pointing at tables dropped during operations simulating unsupported table alterations because of an unexpected failure to disable foreign key constraint checks. SQLite3 does not allow disabling such checks while in a transaction so they must be disabled beforehand. Thanks ezaquarii for the report and Carlton and Tim for the review.
2018-12-10Refs #28670 -- Fixed DatabaseFeatures.supports_slicing_ordering_in_compound ↵Mariusz Felisiak
on Oracle.
2018-12-07Fixed #29182 -- Fixed schema table alteration on SQLite 3.26+.Simon Charette
SQLite 3.26 repoints foreign key constraints on table renames even when foreign_keys pragma is off which breaks every operation that requires a table rebuild to simulate unsupported ALTER TABLE statements. The newly introduced legacy_alter_table pragma disables this behavior and restores the previous schema editor assumptions. Thanks Florian Apolloner, Christoph Trassl, Chris Lamb for the report and troubleshooting assistance.
