[Bug 1101206] Re: bzr selftest fails with "bzr: ERROR: No module named subunit" when option --parallel=fork is set

[Jean-Baptiste Lallement]

Reopened and set to triaged following discussion with vila on IRC during
which we came to the conclusion in comment #2

** Changed in: bzr (Ubuntu)
       Status: Invalid => New

** Changed in: bzr (Ubuntu)
       Status: New => Triaged

** Summary changed:

- bzr selftest fails with "bzr: ERROR: No module named subunit" when option --parallel=fork is set
+ autopkgtest failed with "No module named subunit" - missing test dependency on python-subunit

** Description changed:

- autopkgtest of bzr running in the QA Lab (https://jenkins.qa.ubuntu.com/view/Raring/view/AutoPkgTest/job/raring-adt-bzr/) fails with:
+ autopkgtest of bzr running in the QA Lab (https://jenkins.qa.ubuntu.com/view/Raring/view/AutoPkgTest/job/raring-adt-bzr/) fails with 
  """
  bzr: ERROR: No module named subunit
  You may need to install this Python library separately.
  """
  
- when bzr selftest is called with the option parallel=fork
+ when when running on multicore systems and bzr selftest is called with
+ the option parallel=fork
  
  selftest runs fine without this option and subunit tests are correctly
  skipped.
  
- The tests are running on a minimal raring server VM. The host of the VM
- is Precise Server amd64. This is 100% reproducible in the QA Lab either
- with autopkgtest or manually with the command "bzr selftest -v
- --parallel=fork"  but does not occur on on my local machine with the
- same testing environment.
- 
- To reproduce the testing environment:
- 1. $ bzr branch lp:auto-package-testing
- 2. $ cd auto-package-testing/bin
- 3. $ ./prepare-testbed amd64
- 4. $ ./run-adt-test bzr
+ There is either a missing test dependency on python-subunit in
+ debian/tests/control or --parallel=fork should be removed to run the
+ test on machines where local_concurrency is > 1
  
  Log of autopkgtest attached.
