Description: 

Hi, I'm in the process of packaging dependencies for the Evergreen library system (http://evergreen-ils.org) in the hopes that one day we will be able to install Evergreen via yum.

This package is one of the core requirements for library systems as it deals with a legacy data encoding dating from the 70's that needs to be converted to UTF8 to be useful to most software. Making this package available in Fedora will benefit not just Evergreen, but also Koha and other library systems that use Perl.

I work closely with my peers in the code4lib community and speak with the previous and current maintainers of the Perl MARC packages on a nearly-daily basis.

Comment 1 Dan Scott 2012-06-07 19:46:19 UTC
In anticipation of a comment regarding the arch specificity of the package and rpmlint's report that it found no binary, perl-MARC-Charset creates a GDBM_File binary object that is not portable. It stores this object in the same Perl directory as the MARC/Charset/Table.pm module.

In an effort to prevent two arch-specific packages from being installed on the same system and thereby clobbering one another, I've introduced a symbolic link that points at libdir from MARC/Charset/Table. My intention is that this should introduce a conflict should someone attempt to install two versions of the same arch-specific package. (Debian appears to take the same approach, for whatever that's worth).

I checked on #fedora-devel and there didn't seem to be horrified reactions, and they also suggested that rpmlint's warning about no-binary could be ignored as it doesn't understand gdbm, but this is my first time dealing with an oddity like this. If there's a better recommended practice, I'm all ears.

Comment 2 Dan Scott 2012-06-07 20:11:52 UTC
Also, this is my first package review request and I do need a sponsor :)

Comment 3 Iain Arnell 2012-06-10 19:00:28 UTC
Okay, I'll bite - if only because I live in a community called Evergreen and we don't have a public library system - maybe this will help ;)

It's very promising that you noticed the arch-dependent nature of the package and came up with a solution. I had a similar issue with perl-Lingua-EN-Tagger which I resolved by making the whole package arch-dependent, passing INSTALLVENDORLIB=%{perl_vendorarch} to Makefile.PL so that the whole package gets installed under %{_libdir}/perl5/vendor_perl. And since this approach avoids conflicts entirely, I guess it counts as a better recommended practice.

You're quite right that rpmlint's no-binary "error" can be ignored in this case, but we also build debuginfo packages and rpmlint also complains about empty-debuginfo-package. In this case, it's appropriate to disable debuginfo package by adding %global debug_package %{nil} to the spec file. (see https://fedoraproject.org/wiki/Packaging:Debuginfo for more info).

Otherwise, it's a fairly simple package. There's just a few minor issues:

you don't need to specify the BuildRoot tag - https://fedoraproject.org/wiki/Packaging/Guidelines#BuildRoot_tag

you don't need to explicitly Require: perl(Unicode::Normalize) - rpm detects this dependency automatically.

you should explicitly BuildRequire any dependencies that are part of perl-core itself - although they're pulled in as transient dependencies at the minute, they might not be in future (the Red Hat perl folks tend to pretty insistent on this):
  perl(base)
  perl(Carp)
  perl(charnames)
  perl(constant)
  perl(Encode)
  perl(POSIX)
  perl(Storable)
  perl(strict)
  perl(Unicode::Normalize)
  perl(Unicode::UCD)
  perl(warnings)

And as a sponsor, it would also be nice to see a couple of informal reviews of other packages. https://fedoraproject.org/wiki/How_to_get_sponsored_into_the_packager_group

Comment 4 Iain Arnell 2012-06-10 19:19:38 UTC
Nearly forgot - you should also use DESTDIR instead of PERL_INSTALL_ROOT in %install section. Bug 562316 has some background.

Comment 5 Dan Scott 2012-06-11 03:32:29 UTC
Iain: thanks so much for your detailed review comments! I do hope that Evergreen (http://evergreen-ils.org) will be useful to the community of Evergreen; you can always pass my contact info on for help if that comes to pass.

I've revised the package SPEC and SRPM according to your advice (and added a line to the ChangeLog crediting you for your feedback):

Spec URL: http://bzr.coffeecode.net/scratch/perl-MARC-Charset/perl-MARC-Charset.spec
SRPM URL: http://bzr.coffeecode.net/scratch/perl-MARC-Charset/perl-MARC-Charset-1.33-1.fc17.src.rpm

In retrospect, pointing at %{perl_vendorarch} seems like the obvious way to solve the arch-specific problem. Thanks for your other suggestions, as well, that in some cases helped turn a statement of fact ("Fedora does not require the presence of the BuildRoot tag") into a prescriptive guideline ("Do not include the BuildRoot tag.") or flagged an archaic practice (not using DESTDIR for the install argument).

I have also delved back into a number of the packaging documents to increase my familiarity with the guidelines, which were pretty overwhelming on my first pass through them. I plan on reviewing other package submissions, but wanted some reassurance that I was on the right track and wouldn't be misdirecting other would-be packages. Thanks so much for your generous donation of time to help me out!

As mentioned earlier, rpmlint's no-binary "error" can be ignored. There are no blockers, so this package is APPROVED.

Although I've not yet formally reviewed your other packages (sorry, a bit pushed for time today), the changes you made seem to be appropriate. You obviously know what you're doing, respond well to feedback, and the bonus points show some familiarity with our build system. I'm very pleased to welcome you as the latest member of the team.

When making the SCM request for this package (and the others, once I've reviewed them - hopefully tomorrow), please add me (iarnell) and perl-sig to the IntialCC section. 

And if you haven't already joined Fedora's perl-devel mailing list, I strongly suggest doing so - you might want to filter out the bug/git spam, though.

New Package SCM Request
=======================
Package Name: perl-MARC-Charset
Short Description: Converts data encoded in MARC-8 to Unicode (UTF-8)
New Branches: f17

Comment 9 Iain Arnell 2012-06-13 01:15:41 UTC
Doh! I missed something obvious. When you check this in, please add a BuildRequires: perl(ExtUtils::MakeMaker). At the minute, it's pulled in as a dependency of perl-Test-Simple via perl-devel - that may change in future as Test-Simple probably shouldn't require EU::MM. My bad, but no real problem.

Comment 11 Iain Arnell 2012-06-15 14:13:11 UTC
The process-git-requests script seems to have ignored your request for f17 branch. I guess it's very picky. For New Package requests, it seems to want "Branches:". You can fix it by making a Package Change Request - which does want "New Branches:".

Comment 12 Dan Scott 2012-06-15 14:20:19 UTC
Package Change Request

My bad for initially grabbing the template for "Package Change Request" and filling it out, then realizing that I needed the "New Package Change Request" template, but failing to modify "New Branches:" to "Branches:" as well. Thanks again Iain!
