Description Lon Hohberger 2002-04-16 15:30:09 EDT
Description of Problem:
Cluadmin does not exit cleanly when sent a TERM signal - it does not release the
cluster session lock.

Version-Release number of selected component (if applicable): 1.0.11-1

How Reproducible: Always.

Steps to Reproduce:
1. Run cluadmin.
2. Log in on another pty and run "killall -TERM cluadmin"
3. Run cluadmin again.

Actual Results:
Nasty message asking if you want to seize the cluster session lock when cluadmin
is run after it's been TERMinated.

Expected Results:
Clean reentry.

Comment 1 Lon Hohberger 2002-06-21 11:36:26 EDT
Enhancements in pool.  As a side effect, I also changed the lack of handling of
Ctrl-C in the same manner, making the UI part of cluadmin *slightly* more sane -
any complete 'commit' operation succeeds, but I also note that signals are
ignored _during_ all operations involving writing the cluster database:

- Lock
- UnLock
- Write
- WriteFile

So, in a few instances, "Ctrl-C" will be ignored to prevent data corruption.
