Subject: bug#39970: guix commands broken on Azerbaijani 'az_AZ' and Turkish 'tr_TR' locales
Date: Sat, 7 Mar 2020 13:00:52 +0100

[Message part 1 (text/plain, inline)]

After running

export LC_ALL=tr_TR.utf8

many important Guix commands like 'guix environment', 'guix install'
and 'guix pull' fail.

$ guix environment --ad-hoc hello
Backtrace:
           1 (primitive-load "/home/florian/.config/guix/current/bin…")
In guix/ui.scm:
  1826:12  0 (run-guix-command _ . _)

guix/ui.scm:1826:12: In procedure run-guix-command:
In procedure string-length: Wrong type argument in position 1 (expecting string): #f


Running guix via ./pre-inst-env gives a more useful backtrace.  The
reason is that in guix/store.scm

(use-modules (ice-9 regex))
(regexp-exec (make-regexp "^/gnu/store/([0-9a-df-np-sv-z]{32})-([^/]+)$")
             "/gnu/store/bv9py3f2dsa5iw0aijqjv9zxwprcy1nb-fontconfig-2.13.1.drv")

evaluates to #f in Turkish, possibly because of the presence of
dotless i (ı) in the range.

The attached patch fixes the issue by including i explicitly, but I
believe enumerating all of [0-9abcdfghijklmnpqrsvwxyz] explicitly
might be more future-proof.

Shall I push the patch modified to list all letters in
[0-9abcdfghijklmnpqrsvwxyz] explicitly?  Numbers too?  I suppose there
is no downside to listing all without ranges.

I wonder what else is affected; the installer maybe?  I have not
tested yet.

Regards,
Florian
