After a chat with the reporter on IRC,

The point of this request is that some bots active in Catalan projects (ca.wiki...) and currently hosted in the toolserver require this locale. If it is not available in Tools Labs, then such bots will stop working when the old toolserver is shut down on July 1st.

Three months ago I have reported this bug https://bugzilla.wikimedia.org/show_bug.cgi?id=62269 but it was forgotten. Today I wanted remember my post to community and YuviPanda on Cloud-Services has suggested me to create a new bug.

I hope this new request doesn't pass into oblivion.

The component "General" is for "issues surrounding set up of labs projects", while the setup of Wikimedia Tools is managed under the component "tools" ("Issue tracker for the tools.wmflabs.org infrastructure itself. Note: Issues with tools running on Tool Labs should be filed under 'Tool Labs tools'."). So this bug (and bug #62269) didn't appear on the radar of anyone involved with Wikimedia Tools. I'll submit a patch in a few minutes.

Has been merged, should be present in the nodes in about 30minutes. Can you test and verify after that? Thanks!

It works fine.

import locale,time;locale.setlocale(locale.LC_ALL, "ca_ES.UTF-8@valencia");[time.strftime("%B", time.strptime("01-%i-2014" % i, "%d-%m-%Y")) for i in range(1,12)];[time.strftime("%A", time.strptime("%i-1-2014" % i, "%d-%m-%Y")) for i in range(1,7)]

'ca_ES.UTF-8@valencia'
['gener', 'febrer', 'mar\xc3\xa7', 'abril', 'maig', 'juny', 'juliol', 'agost', 'setembre', 'octubre', 'novembre']
['dimecres', 'dijous', 'divendres', 'dissabte', 'diumenge', 'dilluns']

Thanks. (Sorry for my poor English.)

:D Glad this could be fixed!

(And no need to apologize for 'poor English' :) )
