Simon Charette 790d108c97 Refs #30033 -- Checked constraints before committing SQLite schema changes.
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.

Simon Charette 894cb13779 Refs #29182 -- Stopped relying on legacy alter table semantic on SQLite 3.26+.
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.

Simon Charette 7289874adc Fixed #30033 -- Conformed to the recommended table alterations procedure on 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 c8ffdbe514.

Thanks to Richard Hipp for pointing out the usage of the incorrect procedure.

Simon Charette a939d630a4 Refs #29928 -- Implemented fast constraint checking on SQLite 3.20+. 2018-12-17 10:44:05 +01:00
Simon Charette 315357ad25 Fixed #30023 -- Prevented SQLite schema alterations while foreign key checks 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.

Simon Charette c8ffdbe514 Fixed #29182 -- Fixed schema table alteration on SQLite 3.26+.
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.
