# Test case temptrigger-1.* demonstrates a problem with temp triggers
|
|
# in shared-cache mode. If process 1 connections to a shared-cache and
|
|
# creates a temp trigger, the temp trigger is linked into the shared-cache
|
|
# schema. If process 2 reloads the shared-cache schema from disk, then
|
|
# it does not recreate the temp trigger belonging to process 1. From the
|
|
# point of view of process 1, the temp trigger just disappeared.
|
|
#
|
|
# temptrigger-1.1: In shared cache mode, create a table in the main
|
|
# database and add a temp trigger to it.
|
|
#
|
|
# temptrigger-1.2: Check that the temp trigger is correctly fired. Check
|
|
# that the temp trigger is not fired by statements
|
|
# executed by a second connection connected to the
|
|
# same shared cache.
|
|
#
|
|
# temptrigger-1.3: Using the second connection to the shared-cache, cause
|
|
# the shared-cache schema to be reloaded.
|
|
#
|
|
# temptrigger-1.4: Check that the temp trigger is still fired correctly.
|
|
#
|
|
# temptrigger-1.5: Check that the temp trigger can be dropped without error.
