bzr fails to build on vivid (release) and trusty (test-rebuild only)

bzr fails to build on vivid (release) and trusty (test-rebuild only)

various test failures seen, likely exposed by python 2.7.10.

release:
https://launchpad.net/ubuntu/+archive/test-rebuild-20150402/+build/7133674

test rebuild:
https://launchpad.net/ubuntu/+archive/test-rebuild-20150501-updates/+build/7375272

how to validate: successful build. the testsuite is run during the build

Sorry for the reply delay :-/

I've been able to reproduce on vivid.

These tests are racy (yet another occurrence of running a TCP server and client in the same process (different threads)).

Out of the ~800 http tests, those two ones are the simplest: they connect to an http server that always reply with a 'Bad status' message and close the connection.

Running 'bzr selftest --parallel=fork -v -s bt.test_http.TestBadStatusServer' repeatedly, I can:
- see the test pass,
- see the test fail as reported,
- see the test hang

Definitely a race :-/

This can be fixed in two ways:
- run the server in a separate process,
- identify the race more precisely and fix it.

The former requires some tedious work, the later requires some deep investigation :-/

I've sent a patch to debian to disable these tests until they are properly fixed. We don't lose significant coverage doing so (pqm will still run them to gate lp:bzr).

fixed in 2.6.0+bzr6602-2ubuntu2 in wily. backporting the same fix to trusty

Hello Matthias, or anyone else affected,

Accepted bzr into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/bzr/2.6.0+bzr6593-1ubuntu1.3 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!

my bad, the second patch to fix the win32 paths tests only works with python 2.7.9 and .10. I'll keep it in -proposed for now, keeping the verification-needed tag.

[Matthias Klose (doko)]

no, please keep it this way. it succeeds with the python2.7 proposed for trusty

[Mathew Hodson (mhodson)]

Do I understand correctly that there needs to be a trusty SRU for python2.7 first to get this to build? Is there a launchpad bug for the proposed python2.7 package?

[Steve Langasek (vorlon)]

There is no python2.7 package currently in the queue or in -proposed for trusty. Trying to rebuild the bzr package in trusty-proposed still fails.

[Mathew Hodson (mhodson)]

Comment #2 says that this was fixed in 2.6.0+bzr6602-2ubuntu2 in wily.

Vivid has 2.6.0+bzr6595-6ubuntu1, so I don't think a fix was ever released there.

[tony hutcherson (tnhutcherson472)]

system still wont work did all sugg. still get get to work right

verified again, that the package in -proposed builds fine with the python2.7 from the ubuntu-toolchain-r/ppa PPA. The tests are dependent on 2.7.9 or higher.
