[Bug 907704] New: Use the plain `perl` command instead of the `%{_perl}` macro in generated specfiles

            Bug ID: 907704
           Summary: Use the plain `perl` command instead of the `%{_perl}`
                    macro in generated specfiles
           Product: Fedora
           Version: 18
         Component: cpanspec
          Severity: unspecified
          Priority: unspecified
          Reporter: bochecha(a)fedoraproject.org

Description of problem:
In all my recent perl-related package submissions, the reviewer has suggested
to me to use the plain `perl` command instead of the `%{_perl}` macro.

For example:
 %build
-%{__perl} Makefile.PL INSTALLDIRS=vendor OPTIMIZE="%{optflags}"
+perl Makefile.PL INSTALLDIRS=vendor OPTIMIZE="%{optflags}"
 make %{?_smp_mflags}

Now, of course I'll try to pay more attention to it, or else reviewers will be
tired of always repeating the same thing. :)

However, it would be very helpful if cpanspec could create specfiles which
directly respect our experts' recommendations, so that we don't have to change
it for every package.

This is with:
cpanspec-1.78-12.fc18.noarch

--- Comment #1 from Steven Roberts <strobert(a)strobe.net&gt; ---
Have you found and refs for this?

Only things I found related in the packaging guidelines:
https://fedoraproject.org/wiki/Packaging:Perl

shows it as %{__perl} and not perl.

I would recommend asking the perl-sig folks to see what the thought is on this.
 and if going to perl from %{__perl} is the desired path going forward, let's
get it changed on the guidelines page and then we can work on getting a change
upstream into cpanspec.

--- Comment #2 from Petr Pisar <ppisar(a)redhat.com&gt; ---
Main packaging guidelines discourage using macros for plain commands
<https://fedoraproject.org/wiki/Packaging:Guidelines#Macros>;:

Macro forms of system executables SHOULD NOT be used except when there is a
need to allow the location of those executables to be configurable. For
example, rm should be used in preference to %{__rm}, but %{__python} is
acceptable.

a) %__perl is in a similar position as %__python.

b) The wording "SHOULD NOT" means %__perl or other macros are _allowed_


=> It's up to a packager's discretion to use it or not. I encourage people to
use it and consider people enforcing plain "perl" to commit a mistake.

--- Comment #4 from Fedora End Of Life <endoflife(a)fedoraproject.org&gt; ---
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '18'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior to Fedora 18's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

--- Comment #5 from Fedora End Of Life <endoflife(a)fedoraproject.org&gt; ---
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
