| 27 # Test case temptrigger-1.* demonstrates a problem with temp triggers |
| 28 # in shared-cache mode. If process 1 connections to a shared-cache and |
| 29 # creates a temp trigger, the temp trigger is linked into the shared-cache |
| 30 # schema. If process 2 reloads the shared-cache schema from disk, then |
| 31 # it does not recreate the temp trigger belonging to process 1. From the |
| 32 # point of view of process 1, the temp trigger just disappeared. |
| 33 # |
| 34 # temptrigger-1.1: In shared cache mode, create a table in the main |
| 35 # database and add a temp trigger to it. |
| 36 # |
| 37 # temptrigger-1.2: Check that the temp trigger is correctly fired. Check |
| 38 # that the temp trigger is not fired by statements |
| 39 # executed by a second connection connected to the |
| 40 # same shared cache. |
| 41 # |
| 42 # temptrigger-1.3: Using the second connection to the shared-cache, cause |
| 43 # the shared-cache schema to be reloaded. |
| 44 # |
| 45 # temptrigger-1.4: Check that the temp trigger is still fired correctly. |
| 46 # |
| 47 # temptrigger-1.5: Check that the temp trigger can be dropped without error. |
