[Expired for software-center (Ubuntu) because there has been no activity for 60 days.]

This is a race condition in httplib2, but we can probably fix it in piston-mini-client via a try/except os.makedirs() if the cachedir does not exists.

Thanks for uploading the fix for this bug report to -proposed. However, when reviewing the package in -proposed and the details of this bug report I noticed that this bug is not fixed in the development release of Ubuntu. Before we can accept the package in -proposed the bug related bug must be fixed in the development release. Thanks!

[Michael Vogt (mvo)]

Thanks Brian, this is in quantal now so the precise-proposed version can get unblocked.

This bug was fixed in the package piston-mini-client - 0.7.2+bzr57-0ubuntu2

---------------
piston-mini-client (0.7.2+bzr57-0ubuntu2) quantal; urgency=low

  * initial upload to quantal

piston-mini-client (0.7.2+bzr57-0ubuntu1) precise-proposed; urgency=low

  * Fix race when multiple piston-mini-client helpers try to create
    a cache directory (LP: #803280)

Hello Ivan, or anyone else affected,

Accepted piston-mini-client into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Sebastien Bacher (seb128)]

Michael, Gary, could one of you test that update?

[Michael Vogt (mvo)]

I'm running this version on my precise box since its available in proposed and couldn't see any regressions. Also not in the bugreports or errors.ubuntu.com. I mark it as done.
