RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Example of patch to address this error.

Description of problem:
fence_apc caught KeyError: '-p'

Version-Release number of selected component (if applicable):
fence-agents-3.1.5-10.el6

How reproducible:
Always.

Steps to Reproduce:
1. Issuing fence_apc command with -l (login) option
2.
3.
  
Actual results:
# fence_apc -l rio -n 1 -a 10.64.193.159 -o off
Traceback (most recent call last):
  File "/usr/sbin/fence_apc", line 243, in <module>
    main()
  File "/usr/sbin/fence_apc", line 222, in main
    conn = fence_login(options)
  File "/usr/share/fence/fencing.py", line 949, in fence_login
    conn.send(options["-p"] + login_eol)
KeyError: '-p'

Expected results:
# fence_apc -l rio -n 1 -a 10.64.193.159 -o off

I wrote a patch but it may affect other fence agents.

Proposed patch

@Ryo:

Thanks for reporting. You are right that yours patch can hurt other agents (e.g. WTI devices can be used with login name and without password). But thanks to your report, it was quite easy to create a new patch. Feel free to comment it if needed, I believe that next week (after review on mailing list) I will create a new upstream version
Comment 3 ryo fujita 2012-01-31 00:51:30 UTC 
I read your patch and totally understand how to patch the issue. Your patch is so simple!
Comment 4 Marek Grac 2012-02-08 16:44:14 UTC 
Patch is now part of upstream at:

http://git.fedorahosted.org/git/?p=fence-agents.git;a=commit;h=57ae9aa78b1d6bed89551944a8e0b5fa6c1f0075
Comment 6 Marek Grac 2012-02-20 15:43:28 UTC 
Unit test & results:

# fence_apc -l LOGIN -n 1 -a IP_APC -o status
Traceback (most recent call last):
  File "/usr/sbin/fence_apc", line 243, in <module>
    main()
  File "/usr/sbin/fence_apc", line 222, in main
    conn = fence_login(options)
  File "/usr/share/fence/fencing.py", line 949, in fence_login
    conn.send(options["-p"] + login_eol)
KeyError: '-p'

after applying patch:

# fence_apc -l LOGIN -n 1 -a IP_APC -o status
Failed: You have to set login password
