[SRU] swift-proxy needs python-happybase >0.5 !=0.7, but 0.7 is present in the repository when used with ceilometer

[Zoltan Martha]

[Impact]
The ceilometer extension for swift is currently broken and causes swift-proxy to fail on startup if enabled.

[Test Case]
sudo apt-get install swift-proxy python-ceilometer
Enable ceilometer egg in proxy filter chain.
sudo service swift-proxy start
(fails with stacktrace below).

[Regression Potential]
Proposal is to update happybase to 0.8 (requirement bump came late in cycle and was missed). Ceilometer is the only reverse-depends.

[Original Bug Report]
Affected release:
Description: Ubuntu 14.04 LTS
Release: 14.04

Affected packages:
python-swift:
  Installed: 1.13.1-0ubuntu1
  Candidate: 1.13.1-0ubuntu1
python-happybase:
  Installed: 0.7-1build1
  Candidate: 0.7-1build1

The swift-proxy service fails to start.

Status changed to 'Confirmed' because the bug affects multiple users.

[David Moreau Simard (dmsimard)]

This is linked to another dependency problem in bug https://bugs.launchpad.net/ubuntu/+source/swift/+bug/1317147.

[James Page (james-page)]

The problem is actually in ceilometer - raising bug task

[James Page (james-page)]

Hmm - this is odd as the version of happybase in trusty and the Icehouse UCA is 0.7

[James Page (james-page)]

sorry - read the version check wrong...

[James Page (james-page)]

As the version in 14.04 of happybase appears to be quite broken, I'll see if we can push in 0.8 - ceilometer is the only in-distro consumer of this package.

[Scott Kitterman (kitterman)]

Hello Zoltan, or anyone else affected,

Accepted python-happybase into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/python-happybase/0.8-0ubuntu1 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 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, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

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

[Zoltan Martha (marthazoli)]

Hello Scott,

I'm proceeding with the verification phase according to the wiki page you provided.

Best regards,
Zoltan

Scott / James:

What is the general process for the cloud archive ? Are the fixes backported/cherry-picked from the current stable branch (trusty) once they make it out of proposed ?

[Zoltan Martha (marthazoli)]

Results of the verification test:
1. Reinstalled 14.04 with disabled trusty-proposed repository.
2. Performed openstack installation as before.
3. Verified and corrected the pecan-bug with new packages, described here: https://bugs.launchpad.net/ubuntu/+source/ceilometer/+bug/1317147
4. Reproduced the bug.
5. Activated the proposed repository and performed aptitude update.
6. Installed happybase 0.8 from proposed.
7. Started swift-proxy service, contents of the logfile:
No proxy-server running
Starting proxy-server...(/etc/swift/proxy-server.conf)

The new happybase package seems to resolve the original issue.

[James Page (james-page)]

@David

I'll push over the proposed packages to the Cloud Archive today.
