Description Uwe Müssel 2004-12-30 08:54:14 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)
Gecko/20041107 Firefox/1.0

Description of problem:
When a custom defined service is started by the clustermanager via
script, a lot of signals including SIGUSR1 and SIGUSR2 are blocked.
Programms relying on these signals will not work correctly.

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

How reproducible:

Steps to Reproduce:
1. Install the screen package
2. create a cluster service unsing the attached test_script as user
script. This scripts simply starts a shell in a screen session
3. start the service 
4. attach to the session by entering "screen -r"
5. enter: trap ls 10
6. enter: kill -10 $$

Actual Results:  Nothing happens.

Expected Results:  The content of the current direcotry should appear
as it is if you start the screen session on the commansline by
entering "test_script start"

Fixes problem

This patch changes clusvcmgrd to correctly unblock all signals prior to
starting the service script(s).

1.2.23 packages have a bug which prevents IP addresses from properly
starting in some cases.

Consequently, I have fixed this problem and made a new test package:

Verified with the sigtest program.  It starts, and it fails over
properly.  Version clumanager-1.2.25-2.  Scheduled for release RHEL3-U5.
