# This file implements regression tests for SQLite library.
#
# This file implements tests for the sqlite4_trace() and sqlite4_profile() 
# APIs. Specifically, it tests that destructor functions are invoked
# correctly.

#-------------------------------------------------------------------------
# The following tests verify that the profile destructor is
# invoked:
#
#   1. When it is overridden, and
#   2. When the database connection is closed.
#
# It would be good to test that if an error occurs within the 
# collation_needed() the destructor is invoked immediately (as the 
# documentation says). However there is currently no way to cause
# sqlite4_collation_needed() to fail. sqlite4_collation_needed() 
# currently *always* returns SQLITE4_OK.
