Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Description Ryan Blakley 2018-02-21 21:23:38 UTC 
Description of problem:redhat-support-tool: UnboundLocalError: local variable 'timer' referenced before assignment.


Version-Release number of selected component (if applicable): redhat-support-tool-0.9.9-3.el7


Steps to Reproduce:
1. For me to reproduce the issue, I had to bring down my networking.
2. Then run # redhat-support-tool addattachment -c 0XXXXXX -f -z /path/to/file


Actual results:
redhat_support_tool.helpers.launchhelper - ERROR - local variable 'timer' referenced before assignment
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/redhat_support_tool/helpers/launchhelper.py", line 106, in run
    return cls.non_interactive_action()
  File "/usr/lib/python2.7/site-packages/redhat_support_tool/plugins/add_attachment.py", line 437, in non_interactive_action
    useFtp=self.use_ftp)
  File "/usr/lib/python2.7/site-packages/redhat_support_lib/infrastructure/brokers.py", line 612, in add
    amnt = FtpHelper.ftp_attachment(fileName, caseNumber, fileChunk)
  File "/usr/lib/python2.7/site-packages/redhat_support_lib/utils/ftphelper.py", line 135, in ftp_attachment
    timer.stop()
UnboundLocalError: local variable 'timer' referenced before assignment


Expected results: Upload the file to the dropbox.


Additional info: I threw together the below patch, and the customer confirmed after making the changes in the patch, that the issue was resolved and the file uploaded.
