This would be a real pain! Incorrect locales should just be ignored.

Using the standard warnings module this would only happen once for
each python script. This sounds like the more sensible behaviour, but
it sounds like it should be fixed upstream so that the unguarded
setlocale just shows this behaviour. If everyone here agrees with
that maybe someone should ask python to consider this?

Perl spits out a lot of annoying warnings when using a non existing
locale. And it does this for any perl script.
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "jhfjkghf"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
However, I don't say that the problem does not exist in Python. I see a
lot those kind of errors with Perl because I log into servers that don't
have my locale installed. There is not much to do because ssh does not
allow to remove some variables from environment that have been added
server side (with AcceptEnv). It would be better to switch silently to C
locale than to display a lot of useless warnings or just stop.

Is runpy missing from python2.6 ?
Dear Debian Python people, While testing the upgrade of a system to Squeeze, I am experiencing errors like the following: Paramétrage de python-markupsafe (0.9.2-1) ... Could not import runpy module Traceback (most recent call last): File "/usr/bin/pycompile", line 280, in main() File "/usr/bin/pycompile", line 264, in main compile(files, versions, e_patterns) File "/usr/bin/pycompile", line 194, in compile pipe.send(fn) File "/usr/bin/pycompile", line 176, in py_compile stdin.write(filename + '\n') IOError: [Errno 32] Broken pipe Apt-file suggests that runpy is only available in python2.7, that is not installed in my system. But actually, python-markupsafe is not the only module needing runpy: at least python-imaging-tk and python-pkg-resources give me the same error. So I wonder: is it an bug in the above packages, or is runpy missing from python2.6?

Re: common issue: setlocale handling?
* Paul Wise , 2010-08-22, 15:06: I recently got a bug filed on iotop about its setlocale handling (#593846). The issue was unguarded code like: locale.setlocale(locale.LC_ALL, '') which fails with "locale.Error: unsupported locale setting" if user has LC_* set to invalid values in his environment. I don't think this is a bug at all. I'd rather say it's an user error. -- Jakub Wilk signature.asc Description: Digital signature
common issue: setlocale handling?
Hi all, I recently got a bug filed on iotop about its setlocale handling (#593846). With a quick grep of my system I can see code in the following packages that looks like they would probably have the same issue: python-xdg virt-manager virtinst iotop mercurial-common python-hachoir-metadata inkscape cython python-gmenu python-aptdaemon fontypython gmobilemedia Do any of the python code checkers have heuristics that can check for this? There was discussion at DebConf10 about having lintian run external programs to check for things like python coding errors and so on. -- bye, pabs http://wiki.debian.org/PaulWise -- To UNSUBSCRIBE, email to debian-python-requ...@lists.debian.org with a subject of "unsubscribe".
