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 of problem:
In RHEL 6.1's python we backported the optional "timeout" option to various methods of the subprocess.Popen from upstream Python 3 to our python 2.6

Specifically patch 131 in python.src.rpm added the optional "timeout" argument to the following API entrypoints:
  subprocess.call
  Popen.communicate
  Popen.wait
based on the feature that eventually landed in Python 3.3 (this was http://bugs.python.org/issue5673)

Unfortunately this breaks 3rd party code that monkeypatches subprocess.Popen, such as eventlet:

http://www.mail-archive.com/openstack@lists.launchpad.net/msg02545.html

Version-Release number of selected component (if applicable):
Added in python-2.6.6-7.el6 (RHEL 6.1)

How reproducible:
100%

Steps to Reproduce:

Run this python script:
------------------------------------------------------------
import subprocess
old_Popen = subprocess.Popen
class Subclass(old_Popen):
    def wait(self):
        return old_Popen.wait(self)
subprocess.Popen = Subclass
print subprocess.call(['echo', 'foo'])
------------------------------------------------------------

  
Actual results:
Traceback with:
TypeError: wait() got an unexpected keyword argument 'timeout'

Expected results:
Should successfully run the subprocess
