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.

Red Hat Product Errata RHBA-2015:2122 0 normal SHIPPED_LIVE subscription-manager bug fix and enhancement update 2015-11-19 10:31:14 UTC

Description Adrian Likins 2015-02-23 21:03:04 UTC 
Description of problem:
See https://github.com/candlepin/subscription-manager/issues/1006 for
upstream report.

python-rhsm always sets socket.defaulttimeout(60), which applies to
any process that imports the module (like yum via subscription-manager plugin). It was meant to only do this for RHEL5 (reluctantly...) where it is the only
option to set socket timeouts (python 2.3) but accidently does it on any python 2.X version (RHEL5/6/7)

in rhsm/connection.py, the line:

   if sys.version_info[0] == 2 and sys.version_info[0] <= 4:
      socket.setdefaulttimeout(60)

should be:

    if sys.version_info[0] == 2 and sys.version_info[1] <= 4:
       socket.setdefaulttimeout(60)


Regardless of version, setting the defaulttimeout is almost certainly wrong,
and should be replaced with per socket timeouts (newer pythons) or other mechanisms to detect timeouts  (event loops and watchdog timers, etc)

Version-Release number of selected component (if applicable):
Since python-rhsm-1.0.4-1

How reproducible:
See upstream bug report, but 'always'.



Expected results:
The default socket timeout to only be changed on RHEL5 and python 2.3, and
probably not even then.

Comment 5 John Sefler 2015-07-23 21:10:58 UTC 
Demonstrating the failure on RHEL7.1, python-rhsm version...
[root@jsefler-71 ~]# rpm -q python-rhsm python
python-rhsm-1.13.10-1.el7.x86_64
python-2.7.5-16.el7.x86_64
[root@jsefler-71 ~]# cat /usr/local/bin/socketgetdefaulttimeouttest.py
import socket
import yum
yb = yum.YumBase()
print socket.getdefaulttimeout()
yb.getReposFromConfig()
print socket.getdefaulttimeout()
[root@jsefler-71 ~]# python /usr/local/bin/socketgetdefaulttimeouttest.py
None
Loaded plugins: langpacks, product-id
60.0
[root@jsefler-71 ~]# 

^^^^ Notice the value 60.0 



Verifying RHEL7.2, python-rhsm version...
[root@jsefler-72 ~]# rpm -q python-rhsm python
python-rhsm-1.15.3-1.el7.x86_64
python-2.7.5-30.el7.x86_64
[root@jsefler-72 ~]# cat /usr/local/bin/socketgetdefaulttimeouttest.py
import socket
import yum
yb = yum.YumBase()
print socket.getdefaulttimeout()
yb.getReposFromConfig()
print socket.getdefaulttimeout()
[root@jsefler-72 ~]# python /usr/local/bin/socketgetdefaulttimeouttest.py
None
Loaded plugins: langpacks, product-id
None
[root@jsefler-72 ~]# 

^^^^ VERIFIED: the second None value indicates that a default timeout value is no longer being set when run on python 2.7
