Description Stefan Krah 2011-07-28 23:06:18 UTC
Description of problem:

If the current locale is Turkish, setting a new locale fails if
the locale contains an 'I'.


Steps to Reproduce:

Compile and run:

#include <stdio.h>
#include <locale.h>
int
main(void)
{
    char *s;
    printf("%s\n", setlocale(LC_CTYPE, "tr_TR"));
    printf("%s\n", setlocale(LC_CTYPE, NULL));
    s = setlocale(LC_CTYPE, "tr_TR.ISO8859-9");
    printf("%s\n", s ? s : "null");
    return 0;
}

  
Actual results:

[stefan@fedora-14-amd64 ~]$ ./xxx 
tr_TR
tr_TR
null


Expected results:

tr_TR
tr_TR
tr_TR.ISO8859-9


Additional info:

My guess is that somewhere tolower() fails to convert the 'I'
to a proper lowercase 'i' if LC_CTYPE is Turkish.

This issue currently causes failures in the Fedora buildbot for

Comment 1 Stefan Krah 2011-08-02 13:16:14 UTC
The test case works with libc-2.11.1:

   Ubuntu Lucid (libc-2.11.1), OpenSUSE (libc-2.11.1)


But not with:

   Fedora 14 (libc-2.13), Fedora 12 ( libc-2.11.2), Debian lenny (libc-2.7), Gentoo (libc-2.13-r2)



If this is a regression in glibc, perhaps the priority should be
raised (or set).

Comment 5 Stefan Krah 2011-08-16 20:51:48 UTC
Since the (automated) message asked me to test: Yes, of course I could,
but all download links for Fedora-16 pre-release still point to
Fedora-15-beta:

http://fedoraproject.org/get-prerelease.html

Is there an easy way (preferably a network install iso) to get Fedora-16 alpha?
