use pwquality_strerror to get error strings

Authored by sitter on Jun 27 2019, 1:08 PM.



libpwquality has localized error string mappings, no need to reinvent
the wheel here. the previous mapping was fairly incomplete resulting in
cases where one would get the generic "use another password" option
was shown, which is fairly meh as it can mean literally anything.

should libpwquality for whatever reason fail to provide a string we will
still fall back to the unfortunate generic default. better than nothing
I suppose.

also carry around auxerror. it contains data such as how many digits
would have been reuired. auxerror doesn't need freeing it simply contains
pointers to internals for the benefit of pwquality_strerror

CHANGELOG: Password quality problems are better explained in the UI

Test Plan

password 'a' now gets error'd as a palindrom rather than the generic error. other errors such as too-short, no-match continue to be reported properly as well

Shouldn't be fromUtf8 ? You can't handle all languages by latin.

Oh, indeed!

Concept makes sense.

@ltoscano can you confirm you're ok from an i18n side.

ping @ltoscano

Sorry, I totally missed the notifications (but I received them).

I think that there is an encoding issue with any characters over the canonical 127 base ones. Observed with Italian and Ukrainian, see


Is that with the latest diff (the one changed to fromUtf8)?

LANGUAGE=uk seems to work for me

My bad, there were some typos in the value of the variable.

I confirm that it works. +1 from the translation point of view.
