RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Per Nystrom 2011-09-13 04:41:55 UTC
+++ This bug was initially created as a clone of Bug #726536 +++

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
the Python project:

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).

* was pushed to the Fedora 16 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing glibc-2.14.90-5'
as soon as you are able to.

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?
