| 22 # Simple locking test case: |
| 23 # |
| 24 # lock2-1.1: Connect a second process to the database. |
| 25 # lock2-1.2: Establish a RESERVED lock with this process. |
| 26 # lock2-1.3: Get a SHARED lock with the second process. |
| 27 # lock2-1.4: Try for a RESERVED lock with process 2. This fails. |
| 28 # lock2-1.5: Try to upgrade the first process to EXCLUSIVE, this fails so |
| 29 # it gets PENDING. |
| 30 # lock2-1.6: Release the SHARED lock held by the second process. |
| 31 # lock2-1.7: Attempt to reaquire a SHARED lock with the second process. |
| 32 # this fails due to the PENDING lock. |
| 33 # lock2-1.8: Ensure the first process can now upgrade to EXCLUSIVE. |
