#-------------------------------------------------------------------------
# Test structure:
#
# without_rowid3-1.*: Simple tests to check that immediate and deferred foreign key 
#            constraints work when not inside a transaction.
#            
# without_rowid3-2.*: Tests to verify that deferred foreign keys work inside
#            explicit transactions (i.e that processing really is deferred).
#
# without_rowid3-3.*: Tests that a statement transaction is rolled back if an
#            immediate foreign key constraint is violated.
#
# without_rowid3-4.*: Test that FK actions may recurse even when recursive triggers
#            are disabled.
#
# without_rowid3-5.*: Check that if foreign-keys are enabled, it is not possible
#            to write to an FK column using the incremental blob API.
#
# without_rowid3-6.*: Test that FK processing is automatically disabled when 
#            running VACUUM.
#
# without_rowid3-7.*: Test using an IPK as the key in the child (referencing) table.
#
# without_rowid3-8.*: Test that enabling/disabling foreign key support while a 
#            transaction is active is not possible.
#
# without_rowid3-9.*: Test SET DEFAULT actions.
#
# without_rowid3-10.*: Test errors.
#
# without_rowid3-11.*: Test CASCADE actions.
#
# without_rowid3-12.*: Test RESTRICT actions.
#
# without_rowid3-13.*: Test that FK processing is performed when a row is REPLACED by
#             an UPDATE or INSERT statement.
#
# without_rowid3-14.*: Test the ALTER TABLE and DROP TABLE commands.
#
# without_rowid3-15.*: Test that if there are no (known) outstanding foreign key 
#             constraint violations in the database, inserting into a parent
#             table or deleting from a child table does not cause SQLite
#             to check if this has repaired an outstanding violation.
#
# without_rowid3-16.*: Test that rows that refer to themselves may be inserted, 
#             updated and deleted.
#
# without_rowid3-17.*: Test that the "count_changes" pragma does not interfere with
#             FK constraint processing.
# 
# without_rowid3-18.*: Test that the authorization callback is invoked when processing
#             FK constraints.
#
# without_rowid3-20.*: Test that ON CONFLICT clauses specified as part of statements
#             do not affect the operation of FK constraints.
#
# without_rowid3-genfkey.*: Tests that were used with the shell tool .genfkey
#            command. Recycled to test the built-in implementation.
#
# without_rowid3-dd08e5.*:  Tests to verify that ticket dd08e5a988d00decc4a543daa8d
#                  has been fixed.
