| 28 # Test case temptrigger-1.* demonstrates a problem with temp triggers | |
| 29 # in shared-cache mode. If process 1 connections to a shared-cache and | |
| 30 # creates a temp trigger, the temp trigger is linked into the shared-cache | |
| 31 # schema. If process 2 reloads the shared-cache schema from disk, then | |
| 32 # it does not recreate the temp trigger belonging to process 1. From the | |
| 33 # point of view of process 1, the temp trigger just disappeared. | |
| 34 # | |
| 35 # temptrigger-1.1: In shared cache mode, create a table in the main | |
| 36 # database and add a temp trigger to it. | |
| 37 # | |
| 38 # temptrigger-1.2: Check that the temp trigger is correctly fired. Check | |
| 39 # that the temp trigger is not fired by statements | |
| 40 # executed by a second connection connected to the | |
| 41 # same shared cache. | |
| 42 # | |
| 43 # temptrigger-1.3: Using the second connection to the shared-cache, cause | |
| 44 # the shared-cache schema to be reloaded. | |
| 45 # | |
| 46 # temptrigger-1.4: Check that the temp trigger is still fired correctly. | |
| 47 # | |
| 48 # temptrigger-1.5: Check that the temp trigger can be dropped without error. | |
