My installation of ZWiki leads to a broken product with the following Import Traceback:

 Traceback (most recent call last):
  File "D:/apps/zope/lib/python/OFS/", line 541, in import_product
    product=__import__(pname, global_dict, global_dict, silly)

    return _parse_localename(localename)
  File "Lib/", line 271, in _parse_localename
    raise ValueError, 'unknown locale: %s' % localename
 ValueError: unknown locale: nl_NL_EURO

My system is eCS (OS/2). What do I need to fill in for ZWIKI_LOCALE to work around this?

This sounds like DebianBug:172148 , which includes a patch for your python's

As you guessed, setting ZWIKI_LOCALE to something harmless should be another way to work around this. Does nl_NL work for you ?

I looked up the patch and added the line: fullname = fullname.replace ("_euro", "", 1) to

After restart of Zope Zwiki was available!!!

Thanx for the help, Frank

My traceback complained about the locale being "[email protected]", so the line I had to add at line 216 in was fullname = fullname.replace ("@euro", "", 1)

thanks, Walter

solved --FlorianKonnertz, 2003/02/19 10:30 GMT

I have zope 2.6.1 on Linux ... and all products don't have problems with locales (I use also plone 1.0.3) so, wouldnt it be better if zwiki contains a workaround instead of patching python???

My locale is even more weird: [email protected] I had to add the line for removing the @euro in, but also had to add

'ca_es': ca_ES.ISO8859-1, '[email protected]': ca_ES.ISO8859-15,

to the definition of locale_alias. Now it seems to work.

split up, update --SimonMichael, Mon, 29 Mar 2004 15:46:50 -0800 reply
Zwiki no longer calls getdefaultlocale so I would guess this particular problem has gone away - if not, please post.

See also #769 LookupError: unknown encoding: eucJP prevents Zwiki product initialization which was on this page.

Note, ZWIKI_LOCALE mentioned above no longer has any effect.

I still have this error with ZWiki-0.29.0rc1.tgz :

Hmm. So how do other products work, given this python bug (getlocale breaking on valid locale names). Do none of them call getlocale ?

Data point: it looks as if upgrading to python 2.3 fixes at least the euro problem.

python bug links --SimonMichael, Tue, 30 Mar 2004 11:47:02 -0800 reply
They are still working on this area. See eg PythonBugs:locale (& change status to any), PythonBug:813449 , PythonBug:554676 , PyDoc:locale.html .

So at the moment the recommended fix is upgrade to python 2.3; if that doesn't work or you can't upgrade, you'll have to patch your python eg as in DebianBug:172148 .

Apparently not!

workaround --simon, Wed, 31 Mar 2004 14:40:16 -0800 reply
I have checked in a workaround for 0.29rc2. In this situation it should now log Warning: getlocale() ValueError, WikiNames will not use the system locale at startup and keep going.

0.29rc2 has a workaround, please test --simon, Wed, 31 Mar 2004 15:32:07 -0800 reply
