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