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 Peter Wienemann 2020-12-02 08:14:20 UTC
Description of problem:
The package perl-MIME-Types should pull in the package perl-Encode as dependency. Otherwise the package is unusable:

How reproducible:
always

Steps to Reproduce:
1. yum install perl-MIME-Types
2. Run the following perl script:
-----------------------------------------------
#!/usr/bin/env perl

use warnings;
use strict;
use MIME::Types;

my $mt = MIME::Types->new;

my @types = $mt->listTypes();

foreach (@types) {
        print("$_\n");
}
-----------------------------------------------

Actual results:
cannot open type database in /usr/share/perl5/vendor_perl/MIME/types.db: No such file or directory

Expected results:
message/cpim
message/delivery-status
message/disposition-notification
[...]

Additional info:
Problem is fixed by running:

yum install perl-Encode

Thank you for report. I can confirm the issue. It's easy fix for it.

Comment 2 Jitka Plesnikova 2020-12-02 14:20:06 UTC
I looked deep on it and I found the source the issue.

lib/MIME/Types.pm 
42:    open DB, '<:encoding(utf8)', $db
43:       or die "cannot open type database in $db: $!\n";

open(,':encoding()',) is loading 'PerlIO::encoding'. 'Encode' is loaded in BOOT section of 'PerlIO::encoding'. This require is not found by perl-generators.

'PerlIO::encoding' is provided by perl-libs. So, we have to add 'Encode' to perl-libs as a run-require.
