Introduction

Collection of notes for the Fedora Extras and Fedora.us community project about creation of specfiles for Perl modules and scripts. The targets are the Fedora and Red Hat Linux distributions.

Perl modules

Modules directories

perl (core)

/usr/lib/perl5/5.8.x
The perl core modules are installed under this directory.

site

/usr/lib/perl5/site_perl/5.8.x
CPAN installs modules under this directory.

vendor

/usr/lib/perl5/vendor_perl/5.8.x
Linux distros install modules under this directory.

Modules directories and ExtUtils::MakeMaker / Module::Build

Manual installation procedures

Note: You should also download the file CHECKSUMS (if possible from a different CPAN mirror) and check the integrity of the tarball.

Important Perl modules

<notes>

• Important: the modules Module::Build and CPANPLUS (and all their dependencies) are being added to perl 5.10.
  Source: perl5-porters mailing list; perl 5.9.2 devel; date: 2005-02
  TODO: threads links
• perl5-porters: send email list asking status information about YAML and Module::Signature (scheduled for perl 5.10?)
• Fedora.us: module Module::Signature still under QA

Line 29: Handling the RPATH problem. Check bugzilla entry 1064 - New: perl-XML-LibXML-Common (for < FC2).

Lines 35-37: Eliminates the perllocal.pod file mess. The ExtUtils::MakeMaker target pure_install doesn't create this file. This problem doesn't occur with Module::Build; this module, at least until version 0.25, doesn't create neither this file nor the .packlist file.

Lines 42-43: The use of Module::Signature will generate a couple of problems in the test area:

• the files debug*.list must be deleted before running the tests
• the presence of patches invalidates the use of Module::Signature (BuildConflits: perl(Module::Signature)).

Line 7: RPM packaging group. The group must be a valid one. This can be easily checked against the contents of the file /usr/share/doc/rpm-x.x/GROUPS).

<comment>
Is this the official Fedora.us choice?
(fedora-devel@fedora.us mailing list: What Perl module RPM group?)
</comment>

Line 8: If it is a CPAN perl package, the license will most likely be "GPL or Artistic". See How are Perl and the CPAN modules licensed?

Good candidate places to look for the license information are the README file, the META.yml file, and the pod documentation.

Line 9: If it is a CPAN perl package, it will be something like: http://search.cpan.org/dist/.../

Line 10: If it is a CPAN perl package, it starts with something like: http://www.cpan.org/authors/id/...
The rest of the URL can be found using the CPAN shell (CPAN_FILE line). For example:

cpan> m Module::Build
Module id = Module::Build
    DESCRIPTION  Build, test, and install Perl modules
    CPAN_USERID  KWILLIAMS (Ken Williams <ken@mathforum.org>)
    CPAN_VERSION 0.25
    CPAN_FILE    K/KW/KWILLIAMS/Module-Build-0.25.tar.gz
    ...

Line 11: Definition of the temporary installation base directory (specfile macro BuildRoot). This location is also copied to the variable RPM_BUILD_ROOT.
To avoid conflicts in a machine where several RPM may be built under different accounts, the directory name should contain the name-version-release (NVR) of the package, and the the name of the user (id -u -n) that started the building process.

Line 13: Requirements (missing Requires) and Building requirements.

Automatic versus Manual creation of the requirements list
The RPM package includes a perl related script that can automatically determine the module dependencies. The major problem is that this solution is not backwards compatible (the script exists in RH7.3 but its file access permissions don't include execution).

<comment>
The BuildArch and the Requires macros are missing.
#BuildArch:
BuildRequires:
#Requires:
</comment>

Line 19: It is necessary to use the -n option to specify the distro directory. The default behaviour is to implicity change to the %{name}-%{version} directory but this is no longer valid for perl modules; the macro %name is tipically perl-pkgname (note the prefix 'perl-').

<comment>
%setup -q -n %{pkgname}-%{version}
where pkgname represents the name part of the tar.gz (assuming a standard CPAN package name - %{pkgname}-%{version}.tar.gz; there are several exceptions)
</comment>

Lines 23-24: Discussion about ExtUtils::MakeMaker Makefile variables: site_perl vs. vendor_perl

<comment buildarch="noarch">
removestrings('CFLAGS="..."', 'OPTIMIZE="..."') if $BuildArch eq "noarch";
</comment>

Lines 29-31: These lines are the solution to overcome the problems with broken DESTDIR and PREFIX in several ExtUtils::MakeMaker versions (e.g. the one included in perl-5.8.0)

<warning>
PERL_INSTALL_ROOT is an environment variable used by the ExtUtils::Install module. It doesn't exists in the Makefile.
</warning>

Lines 32-33:

<comment>
Removal of perllocal.pod info will most likely result in incomplete CPAN snapshots (CPAN autobundle command)
(TODO: browse the CPAN module code)
</comment>

<comment>
Removal of .packlist will most likely break manual removal. You should use the rpm command to remove it.
See CPAN FAQ: How do I remove installed Perl modules?
</comment>

<comment buildarch="noarch">
split the find command in two:
1) findanddelete('perllocal.pod', '.packlist')
2) findanddelete('*.bs')
print 2) unless $BuildArch eq "noarch";
</comment>

Line 34: Remove empty directories after deleting the files perllocal.pod, .packlist, and *.bs. This avoids the inclusion of empty directories and helps reducing the number of directories owned by the binary/noarch RPM.

Line 35: Change file access permissions in order to rpmbuild be able to strip the binary files. This problem affects the building process under a normal user account.
(fedora-devel@fedora.us mailing list: Stripping Perl modules)

<comment buildarch="noarch">
print $line[35] unless $BuildArch eq "noarch";
</comment>

Line 38-39:
<comment author="Ville Skytta">
%check sections were added in rpm 4.2, see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=64137 (and /usr/share/doc/rpm-*/CHANGES)

The "|| :" part is a hack that makes it "work" for older rpm (< 4.2) versions as well, or effectively rpm (or actually the shell) skips that line altogether printing an error message about "no job control" or something. But the end result is almost the same, it gets run after the %install section (as long as it is after %install in the spec file for rpm < 4.2). The only small difference is that for rpm >= 4.2, the built in post-%install section scriptlets are run before %check.
</comment>

Line 48: Good candidate documentation files are the README file and the Changelog file. You should exclude files like MANIFEST*, META.yml, and INSTALL.

Line 49: to be replaced by %{perl_vendorlib}; this macro must be conditional defined at the top of the specfile (this macro only exists in RPM 4.3)

<comment author="Ville Skytta">
Change already pending for the next release of fedora-rpmdevtools (0.1.8)
</comment>

Regarding directory ownership, you should check the directores owned by the RPM, in particular the ones under the vendors subtree (/usr/lib/perl5/vendor_perl/5.8.x/). Extra care should be taken when checking perl modules that are in the same namespace of perl core modules. The perl core modules are installed in a different directory tree (/usr/lib/perl5/5.8.x/ instead of /usr/lib/perl5/vendor_perl/5.8.x/).

Perl modules notes

ExtUtils::MakeMaker

• Allows the presence of several Makefile.PL files. The one on the top level directory is the most important.
• Using the target pure_install instead of the target install avoids the creation of the file perllocal.pod (see fedora.us bug 1525).

Module::Build

Module::Build version 0.26 (0.2608) (update check: 0.2804):

• Only allows the presence of one file Build.PL (and in the top level directory).
• Doesn't have the target pure_install.
• Still doesn't create/append the perllocal.pod file (see also CPAN RT ticket 3704 ).
• Still doesn't create the .packlist file (see also CPAN RT ticket 3704 ).

Module::CoreList

This module includes a database with all perl core modules indexed by perl versions. The script corelist is a front-end to this database.

Module::Signature

Module::Signature version 0.44 (update check: 0.54)

• the presence of patches generates a failure. To avoid this a build conflict with Module::Signature must be declared (note really; see below).
• the files debug*.list must be deleted before the tests
• disable the signature tests by renaming the test files (eg: mv t/sig.t t/sig.t.skip) or deleting them

Available tools for creating specfiles

Several scripts that I have come across:

• cpanflute2

  Author:	Chip Turner
  Homepage:	http://perl.pattern.net/
  CPAN:	http://search.cpan.org/~chipt/ (RPM-Specfile)

• cpan2rpm

  Author:	Erick Calder
  Homepage:	http://perl.arix.com/cpan2rpm/
  CPAN:	http://search.cpan.org/~ecalder/

• makerpm

  Author:	Michael De La Rue
  CPAN:	http://search.cpan.org/~mikedlr/

• perl2rpm

  Author:	David Necas (Yeti)
  Homepage:	http://trific.ath.cx/resources/perl2rpm/

• cpanspec

  Author:	Steven Pritchard
  Homepage:	http://www.silug.org/~steve/
  Download:	http://www.silug.org/~steve/software/scripts/perl/
  Note:	This script only tries to generate the specfile (doesn't try to build the RPMS).

• rpm-build-perl

  Author:	Alexey Tourbin, ALT Linux Team
  Homepage:	http://search.cpan.org/dist/rpm-build-perl/
  Download:	http://search.cpan.org/~atourbin/
  Note:	This module looks very promising.

• Ovid

  Author:	Gyepi Sam
  Homepage:	http://search.cpan.org/dist/Ovid/
  Download:	http://search.cpan.org/~gyepi/
