Argh, please have a look at the LP bug for the Russian parts of the bug report.

Created attachment 4949 [details]
patch

This bug still cannot be fixed properly because locale support in glibc was 
done by redneck retards who don't know there are other languages except 
english. This patch will not be of much use sadly.

And FFS, why there are dots (.) in weekdays and months? show me calendar with 
dots, clowns.

Don't reference other bug reporting systems here and attached patches which actually apply.  I applied it this time.

Martin, Ulrich: Due to unexpected side effects of the patch, we ask you to revert it. Software, which caused the initial visible error, was replaced in system, but other do suffer from the patch.

Dmitry, the controversial change you are talking about was proposed two years ago, and it was finally applied in 2011, thus making this particular bug report closed.

If you suggest to revert the change, please file a separate bug report with all necessary references supporting your proposal.

Personally, I concur the change was erroneous, and I certainly reverted it in the glibc package I maintain as soon as I saw its ugly results.  But the original bug report should remain in the "fixed" state nevertheless.

btw, a bug about LC_TIME/abday appears to be filed even before this one: http://sourceware.org/bugzilla/show_bug.cgi?id=10873
Looks like it already contains all necessary references.

Well, I have to comment on this finally.

First of all, the patch that was actually applied (http://git.altlinux.org/gears/g/..git?p=glibc.git;a=commitdiff;h=glibc-2.13-145-gf498392) does something very different from its description (Lowercase month names).  Besides the change of abbreviated month names to lowercase (which is probably OK), it also slipped in a mix of other changes:
- change of abbreviated day names from fixed three-letter form to fixed two-letter form (actually fixes http://sourceware.org/bugzilla/show_bug.cgi?id=10873 which provides a good set of references);
- unjustified addition of trailing dots to abbreviated day names (it's plain wrong);
- unjustified addition of trailing dots to abbreviated month names (it's also plain wrong);
- unjustified change of abbreviated month names from nominative to genitive (it's also wrong and it actually reverts the fix made for http://sourceware.org/bugzilla/show_bug.cgi?id=525);
- unjustified change of abbreviated month names from fixed three-letter form to variable length form (just a nonsense).

Second, the procedure of describing changes, getting an approval from the locale maintainer and providing good references (as described in http://sourceware.org/glibc/wiki/Contribution%20checklist#Qualification_.28Locales.29) was totally scrapped.

What I suggest in the way of recovery is to revert all these unjustified changes.  The only changes that can remain are:
- change of abbreviated month names to lowercase (a fix for this bug report);
- change of abbreviated day names to two-letter form (a fix for http://sourceware.org/bugzilla/show_bug.cgi?id=10873).

Moving the discussion of recovery to http://sourceware.org/bugzilla/show_bug.cgi?id=10873 (abday) and http://sourceware.org/bugzilla/show_bug.cgi?id=14807 (abmon).
