Univention Bugzilla – Bug 40242
UDM: error messages in web server log about missing translation files
Last modified: 2016-03-16 10:24:10 CET
When logging in to the UDM with the language set to English the Apache error.log is spammed with error messages about translation files not being found:
[Mon Dec 14 10:01:06 2015] [error] [client 10.199.92.2] File does not exist: /var/www/univention-management-console/js_$20150912131759$/umc/modules/i18n/en, referer: https://master.mbu-test.intranet/univention-management-console/?lang=en-US
There's one such line for each UDM module the user has access to.
This is, of course, not critical as they're not required for use but it makes debugging of real problems harder if you have to manually filter out harmless messages. Additionally deciding that they're actually harmless requires the administrator to have programming knowledge and to understand how popular translation systems like GNU gettext work.
These files should simply not be requested if the language is set to English ("en").
A similar albeit less annoying (as it only occurs once) message is the following when loading the "ucs-overview" site:
[Mon Dec 14 10:00:48 2015] [error] [client 10.199.92.2] File does not exist: /var/www/ucs-overview/js/ucs/en.json, referer: https://master.mbu-test.intranet/ucs-overview/
Yes, this is really annoying when debugging an english session!

Some files exists for the english language e.g. due to some branding. So it's better to provide just an empty file.
We would need to rebuild every package for this.
Created attachment 7376 [details]
Attached is a patch which adds a internal apache rewrite rule to a empty file so that these errors doesn't show up anymore in the error.log.
Applied that patch.
r66624 | YAML Bug #40242
r66623 | Bug #40242: Deliver empty translation files instead of a 404 Not found error
OK: manual test:
# wget -q http://localhost/univention-management-console/js/umc/modules/i18n/en/nope.json -O -
Leaving in state RESOLVED until it was decided if the overview page could also be modified that way:
[Fri Jan 29 13:19:54 2016] [error] [client 10.205.1.238] File does not exist: /var/www/ucs-overview/js/ucs/en.json, referer: https://10.200.3.35/ucs-overview/

Can you split it into a new bug? Like Moritz said, it is less annoying.
Overview error split to Bug #40564. The rest is already verified.
