bzr 2.6.0: throws TypeError: first argument must be string or compiled pattern

[dorward (David Dorward)]

Most operations with bzr (including bzr pull) are throwing this error:

  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/re.py", line 247, in _compile
    raise TypeError, "first argument must be string or compiled pattern"
TypeError: first argument must be string or compiled pattern

It appears to be the same as this upstream bug: ​https://bugs.launchpad.net/bzr/+bug/1644003

That bug has an upstream fix. Given the decision not to upgrade in ports ( ​https://trac.macports.org/ticket/52561 ), can the fix be backported?

Downloading the source tree of 2.7.0 from upstream and using that instead of the ports version works around this bug for me (but stops compiled extensions working, so I'd have to install qbzr by hand and maintain that as well as bzr outside of ports if I were to go down that route as a long term solution).

In 0b0703b0/macports-ports:

bzr: Backport upstream patch for python >= 2.7.12

bzr fails to run with specific locales selected in LC_ALL/LANG.
Backport the upstream patch to workaround the problem.

Closes: #53620

[raimue (Rainer Müller)]

Thank you for the report. I could reproduce problem with

LANG=de_DE.UTF-8 LC_ALL=de_DE.UTF-8 bzr pull

I backported the upstream fix to the bzr port.

[dorward (David Dorward)]

I've done a port selfupdate, reinstalled bzr and qbzr and everything appears to be working fine now.

Thanks!
