Hello Michael, or anyone else affected,

Accepted python-eventlet into focal-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/python-
eventlet/0.25.1-2ubuntu1 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in

Title:
  Nova novncproxy doesnt work - unexpected keyword

Status in OpenStack nova-cloud-controller charm:
  Invalid
Status in python-eventlet package in Ubuntu:
  Fix Released
Status in python-eventlet source package in Focal:
  Fix Committed
Status in python-eventlet source package in Groovy:
  Fix Released

Bug description:
  == Impact ==

  SSL secured console access to instances in OpenStack clouds is broken.

  == Test Case ==

  Deploy OpenStack using TLS secured endpoints (juju + charms)
  Boot instance, attempt to access console via dashboard - error in web page and
  error seen in nova-novncproxy log file.

  
  == Regression Potential ==

  Medium - the fix is in eventlet's use of the SSL native library which was broken when wrapping sockets using the SSLContext class.  The fix has been
  accepted upstream and is accompanied with a test case.

  
  == Original Bug Report ==


  Ubuntu Focal (20.04)
  Openstack Ussuri (distro-proposed)
  LXC
  Nova Cloud Controller Charm Rev 68

  When attempting to view the console in Horizon (Openstack Dashboard),
  console frame returns "503 Service Unavailable", when checking the
  nova cloud controller logs for nova-novncproxy, the following error
  appears:

  2020-06-22 17:48:18.262 1463207 INFO nova.console.websocketproxy [-]
  handler exception: wrap_socket() got an unexpected keyword argument
  '_context'

  Google seems to find related issues:
  https://github.com/eventlet/eventlet/issues/526

  as well as:

  https://ask.openstack.org/en/question/127493/nova-novncproxy-fails-to-
  connect-handler-exception-wrap_socket-got-an-unexpected-keyword-
  argument-_context/

  So it seems to be an issue with Python > 3.6, but I cannot downgrade
  python version as it would break nova-novncproxy (already tried)
