Cause
Using bzip2 compression or decompression in Perl code
(e.g. using IO::Compress::Bzip2 Perl module).
Consequence
Perl interpreter complains about missing bzip2 module.
Fix
Support for bzip2 compressions and decompression has
been added and corresponding Perl modules has been
packaged as perl-Compress-Raw-Bzip2 and
perl-IO-Compress-Bzip2 .
Result
Bzip2 algorithm can be used in Perl programs now.

Description

This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. If you would like it considered as an exception in the current release, please ask your support representative. Created attachment 523293 [details]
Patches perl spec file to properly include bzip2 modules
A canned rejection with little rationale is not very helpful. The component doesn't even need to be "updated", beyond fixing the broken spec file. I've included a patch for the spec file which 100% fixes this problem. Rebuilding the perl package with this patched spec will give you 2 new RPMs:
perl-Compress-Raw-Bzip2
perl-IO-Compress-Bzip2
Existing RPMs and sources are not modified in any way, other than an additional dependency in the main package on these new RPMs. The bzip2 package is even fixed to use the system bzlib library, so there's no concern about bundling. I don't see why this useful, 100% compatible fix couldn't be added to a future maintenance release (i.e. RHEL 6.2). Note that I did nothing to the RPM revision number; I'll leave that to Red Hat.
Even if this doesn't make it upstream, hopefully it will help someone else who finds this bug.
Ou, it was probably removed because of conflicts with dual life packages, which provided the same functionality. Thank you for report. Sorry, I'm not sure what packages you are referring to? Are there other packages that implement this bzip2 functionality? I haven't seen any. Perhaps Stepan should be added to the CC list, he should know more about the rationale for removing this. These packages are not in RHEL. It must be fixed in main package. Stepan doesn't have account anymore. OK. I should add that the reason I needed these modules in the first place is cpanspec. Fedora's own cpanspec utility for packaging perl modules will not run on RHEL6 without these modules. perl-IO-Compress-Bzip2 is in EPEL (and cpanspec would presumably go into EPEL also). Does this work for you? Ken, I see no evidence of a perl-IO-Compress-Bzip2 package in my EPEL6 mirror or on the EPEL6 site. Regardless, it wouldn't make sense there anyway. I'm still not certain if anyone is understanding what I'm trying to get across in this bug report. You CANNOT download these modules separately on CPAN; they are bundled into the IO-Compress distribution which is included with the main perl package on RHEL, which then splits it up into a bunch of different RPMs. The only reason these RPMs aren't present in the first place is that the existing perl spec file actually deletes code from the IO-Compress distribution to suppress them (for reasons I do not understand). My patch to the perl spec file fixes this and restores the missing RPMs. (In reply to comment #10) > Ken, I see no evidence of a perl-IO-Compress-Bzip2 package in my EPEL6 mirror > or on the EPEL6 site. Good point. The package is branched but no Koji builds were initiated for el6. https://admin.fedoraproject.org/pkgdb/acls/name/perl-IO-Compress-Bzip2 Sounds like mmaslano will have to weigh in on the best direction forward: fix the perl package in RHEL, or create a new sub-package in EPEL. The correct solution is fix perl package. I was looking into EPEL for hotfix solution, but it's not possible to build perl-IO-Compress-Bzip2 there. The tests are failing in EPEL-6. And that's not the only problem. Since ~2.017 were all IO::Compress merged into one package and you need all IO::Compress::* in the same version for correct functionality. Update in EPEL-6 won't be wise. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. I have this problem too. I have opened a support call directed at this bug.
