Spec file diffs to create powerpc-utils-perl-scripts subpackage none

Description mkumatag 2020-04-01 04:38:53 UTC 
This issue is forked from https://bugzilla.redhat.com/show_bug.cgi?id=1814335

Description of problem:

Rightnow we have a strict dependency on the Perl package for ppc64-diag. But FCOS doesn't ship any perl right now, and it'd be preferable to keep it that way if possible (for example, FCOS doesn't ship python either right now). Do we really need Perl though to support hotplugged devices? Is there a more minimal set of packages that we can install that will do what we want? Can we tweak packaging to make the Perl-requiring bits a separate subpackage?

While addressing the above requirement, we encountered that ppc64-diag requires powerpc-util package which does depend on the Perl, so this bug is to address the Perl deps for the powerpc-utils package. Please refer to the bug mentioned in the first line for any additional information.

Any update/progress on removing the Perl deps for the powerpc-utils package?

> Any update/progress on removing the Perl deps for the powerpc-utils package?

we have 2 options:

#1 : the 1. option is to move drmgr into subpackage powerpc-utils-core and CoreOS should install powerpc-utils-core instead powerpc-utils.

#2 : create powerpc-utils-perl-scripts subpackage (comment 3)
Comment 5 Than Ngo 2020-04-22 15:11:37 UTC 
it's fixed in 1.3.6-6
Comment 8 Eirik Fuller 2020-04-26 20:59:05 UTC 
The RHEL-8.3.0-20200425.n.0 recipe in https://beaker.engineering.redhat.com/jobs/4222981 (https://beaker.engineering.redhat.com/recipes/8181652#task109516715) verifies the presence of the drmgr and rtas_errd commands even in the absence of the perl-interpreter package, with powerpc-utils-core-1.3.6-6.el8 and ppc64-diag-rtas-2.7.6-2.el8, as seen in the following output.

- eval drmgr=$(type -p drmgr) && rtas_errd=$(type -p rtas_errd) && rpm -qf $drmgr && rpm -qf $rtas_errd && dnf -qy --noautoremove remove perl-interpreter && rpm -qf $drmgr && rpm -qf $rtas_errd
powerpc-utils-core-1.3.6-6.el8.ppc64le
ppc64-diag-rtas-2.7.6-2.el8.ppc64le
powerpc-utils-core-1.3.6-6.el8.ppc64le
ppc64-diag-rtas-2.7.6-2.el8.ppc64le
- pass: the command returns 0.

In the RHEL-8.3.0-20200423.n.0 recipe (with powerpc-utils-1.3.6-6.el8 and ppc64-diag-2.7.6-1.el8) drmgr exists in the absence of perl-interpreter but rtas_errd does not exist, as seen in the following output.

- eval drmgr=$(type -p drmgr) && rtas_errd=$(type -p rtas_errd) && rpm -qf $drmgr && rpm -qf $rtas_errd && dnf -qy --noautoremove remove perl-interpreter && rpm -qf $drmgr && rpm -qf $rtas_errd
powerpc-utils-core-1.3.6-6.el8.ppc64le
ppc64-diag-2.7.6-1.el8.ppc64le
powerpc-utils-core-1.3.6-6.el8.ppc64le
- fail: unexpected error code 1.

The dependence of rtas_errd on perl-interpreter in this recipe is a result of RHEL-8.3.0-20200423.n.0 not having the fix for bug 1814335.

In the RHEL-8.3.0-20200422.n.1 recipe (with powerpc-utils-1.3.6-5.el8 and ppc64-diag-2.7.6-1.el8) removing the perl-interpreter package removes drmgr, as seen in the following output.

- eval drmgr=$(type -p drmgr) && rtas_errd=$(type -p rtas_errd) && rpm -qf $drmgr && rpm -qf $rtas_errd && dnf -qy --noautoremove remove perl-interpreter && rpm -qf $drmgr && rpm -qf $rtas_errd
powerpc-utils-1.3.6-5.el8.ppc64le
ppc64-diag-2.7.6-1.el8.ppc64le
- fail: unexpected error code 1.

powerpc-utils-core-1.3.6-6.el8 does not include the patch in attachment 1678816 [details], contrary to what the summary of this bug might suggest, but the fix in powerpc-utils-core-1.3.6-6.el8 does provide a way to satisfy the apparent goals of bug 1814335, with a suitable choice of packages in CoreOS.

I'll move this to VERIFIED under the assumption that having powerpc-utils depend on perl-interpreter does not contradict the goal of this bug; rather, smaller packages (powerpc-utils-core and ppc64-diag-rtas) provide selected binaries with no perl dependency.
Comment 9 Than Ngo 2020-06-05 18:51:55 UTC 
Request the fix for 8.1 and 8.2 zstream
Comment 10 Than Ngo 2020-06-06 08:14:45 UTC 
we do not fix this in 8.1 at all because that's EUS and coreos is going to move off EUS soon!
