# EPEL-8 Packaging Procedures
|
|
|
|
|
|
|
|
|
|
## Introduction
|
|
|
|
|
|
|
|
|
|
When a new Red Hat Enterprise Linux occurs, one of the steps to get
|
|
|
|
|
EPEL going for it is branching of various packages into new
|
|
|
|
|
namespace. The EPEL Steering Committee does not mass branch all
|
|
|
|
|
existing packages into the namespace because it has caused multiple
|
|
|
|
|
problems:
|
|
|
|
|
|
|
|
|
|
1. The package maintainers did not want to support the package in the
|
|
|
|
|
newer version of EPEL. Package maintainers may only want to support
|
|
|
|
|
certain versions of Enterprise Linux or may want to wait until their
|
|
|
|
|
favourite derivative appears.
|
|
|
|
|
|
|
|
|
|
2. The package does not work in the latest version of RHEL. With
|
|
|
|
|
multiple years between releases, software which worked on Fedora 18
|
|
|
|
|
which would branch to EPEL-7 may not exist anymore with Fedora 28 and
|
|
|
|
|
EPEL-8 would need a completely different version.
|
|
|
|
|
|
|
|
|
|
## Consumer request for packages
|
|
|
|
|
|
|
|
|
|
People who are interested in getting packages into EPEL should contact
|
|
|
|
|
the package maintainer through
|
|
|
|
|
[bugzilla](https://bugzilla.redhat.com/). This allows for the requests
|
|
|
|
|
to be tracked and if the primary maintainer is not interested in
|
|
|
|
|
branching to EPEL, other ones can step in and do so.
|
|
|
|
|
|
|
|
|
|
## EPEL Playground
|
|
|
|
|
|
|
|
|
|
We have added an additional set of channels for EPEL-8 called
|
|
|
|
|
playground. It is meant to be sort of like Fedora Rawhide so that
|
|
|
|
|
packagers can work on versions of software which are too fast moving
|
|
|
|
|
or will have large API changes from what they are putting in the
|
|
|
|
|
regular channel.
|
|
|
|
|
|
|
|
|
|
To try and make this transparent, we have made it so when a package is
|
|
|
|
|
built in epel8 it will normally also be built in
|
|
|
|
|
epel8-playground. This is done via a packages.cfg file which lists the
|
|
|
|
|
targets for fedpkg to build against. A successful package build will
|
|
|
|
|
then go through 2 different paths:
|
|
|
|
|
|
|
|
|
|
* epel8 package will go into bodhi to be put into epel8-testing
|
|
|
|
|
* epel8-playground will bypass bodhi and go directly into
|
|
|
|
|
epel8-playground the next compose.
|
|
|
|
|
|
|
|
|
|
If a packager needs to focus only on epel8 or epel8-playground they
|
|
|
|
|
can edit packages.cfg to change the ```target= epel8
|
|
|
|
|
epel8-playground``` to ```target= epel8 ```.
|
|
|
|
|
|
|
|
|
|
Packages in epel8-playground are primarily to be used in the following
|
|
|
|
|
manner:
|
|
|
|
|
|
|
|
|
|
* To test out some new version of the package that might not be stable
|
|
|
|
|
yet.
|
|
|
|
|
|
|
|
|
|
* To test out some new packaging of the package
|
|
|
|
|
|
|
|
|
|
* To test a major version change of the package that they want to land
|
|
|
|
|
at the next epel8 minor release.
|
|
|
|
|
|
|
|
|
|
* To build a package that will never be stable enough for epel8, but
|
|
|
|
|
still could be useful to some.
|
|
|
|
|
|
|
|
|
|
* At minor RHEL releases (ie, 8.1, 8.2) people can pull in big changes
|
|
|
|
|
from playground to the main epel8 packages. Since people will be
|
|
|
|
|
upgrading and paying more attention than usual anyhow at those
|
|
|
|
|
points, it’s a great chance to do that change, but also you want to
|
|
|
|
|
make sure it’s panned out, so you can test before hand in
|
|
|
|
|
playground.
|
|
|
|
|
|
|
|
|
|
Consumers should be aware that packages in EPEL8-playground are there
|
|
|
|
|
without any Service Level Expectations. You may want to only cherry
|
|
|
|
|
pick packages from there as needed.
|
|
|
|
|
|
|
|
|
|
## Developer request for branching multiple packages
|
|
|
|
|
|
|
|
|
|
Branching is handled the same way as requesting a branch using `fedpkg
|
|
|
|
|
request-branch`. A maintainer can request an epel8 branch using
|
|
|
|
|
`fedpkg request-branch epel8` which will create a ticket in
|
|
|
|
|
https://pagure.io/releng/fedora-scm-requests/issues and Release
|
|
|
|
|
Engineering will process these requests.
|
|
|
|
|
|
|
|
|
|
To branch multiple packages please use this or a variant of this
|
|
|
|
|
script:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
#!/usr/bin/sh
|
|
|
|
|
# Reminder to get an updated pagure token for releng tickets
|
|
|
|
|
# Usage: epel-8.sh foo bar goo blah blech
|
|
|
|
|
if [ $# -lt 1 ]
|
|
|
|
|
then
|
|
|
|
|
echo "At least one package name should be provided"
|
|
|
|
|
else
|
|
|
|
|
TMPDIR=`mktemp -d /tmp/epel8.XXXXXX`
|
|
|
|
|
pushd "$TMPDIR"
|
|
|
|
|
for pkg in "$@"
|
|
|
|
|
do
|
|
|
|
|
fedpkg clone "$pkg"
|
|
|
|
|
pushd "$pkg"
|
|
|
|
|
fedpkg request-branch epel8
|
|
|
|
|
fedpkg request-branch epel8-playground
|
|
|
|
|
popd
|
|
|
|
|
done
|
|
|
|
|
rm -rfv "$TMPDIR"
|
|
|
|
|
fi
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Releng will then work through the tickets in the system which is
|
|
|
|
|
adding branches to the PDC and src.fedoraproject.org.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## Known Issues
|
|
|
|
|
|
|
|
|
|
1. /usr/bin/python does not exist. Choose ``/usr/bin/python3`` or
|
|
|
|
|
``/usr/bin/python2`` and patch appropriately.
|
|
|
|
|
|
|
|
|
|
2. ``python2-sphinx`` is not shipped. Most packages should work with
|
|
|
|
|
python3-sphinx, and if it doesn't please open a bug. The python team
|
|
|
|
|
has been good about making fixes for this.
|
|
|
|
|
|
|
|
|
|
3. When branching python packages, be aware that python in EL-8 is
|
|
|
|
|
python36 and not the version currently in rawhide. This has come up
|
|
|
|
|
with a couple of test packages where they assumed python37 or later.
|
|
|
|
|
|
|
|
|
|
4. ``systemd-rpm-macros`` is not a separate packages. If needed, used
|
|
|
|
|
``BuildRequires: systemd``
|
|
|
|
|
|
|
|
|
|
5. While EL-8 comes with platform-python, it should NOT be used in
|
|
|
|
|
``Requires:`` unless absolutely neccessary. python3 should be used
|
|
|
|
|
instead. (Exceptions can be made but will be rare and need
|
|
|
|
|
justification.)
|
|
|
|
|
|
|
|
|
|
**Accepted Exceptions:**
|
|
|
|
|
* Use python3.6dist(coverage) instead of python3-coverage. This
|
|
|
|
|
package is not shipped but is needed in %check code.
|
|
|
|
|
|
|
|
|
|
6. Sometimes RHEL8 only has a python3 package for a dependency you
|
|
|
|
|
need for your build. (Example: python-bleach requires
|
|
|
|
|
python2-html5lib, but RHEL8 provides only python3-html5lib). For
|
|
|
|
|
EPEL-8.0 we only suggest one choice:
|
|
|
|
|
|
|
|
|
|
* Choose not to have the python2 part of your package and patch
|
|
|
|
|
whatever to use python3.
|
|
|
|
|
|
|
|
|
|
7. Python2 packages are discouraged. RHEL-8 will contain python2.7
|
|
|
|
|
until probably the end of life of RHEL-7. However support upstream
|
|
|
|
|
will only be minimal. When modularity occurs, we suggest that you make
|
|
|
|
|
whatever python2 packages modules which can be pulled out when
|
|
|
|
|
RHEL-8.N no longer has python2.
|
|
|
|
|
|
|
|
|
|
8. While a RHEL src.rpm might produce a -devel package, it may not
|
|
|
|
|
currently be in the build repository. When running into this please
|
|
|
|
|
open a ticket with https://pagure.io/epel/new_issue for us to put in a
|
|
|
|
|
request for it to be added to Red Hat's Code Ready Builder. After
|
|
|
|
|
modularity is enabled, changes to what is done will be needed.
|
|
|
|
|
|
|
|
|
|
9. EPEL-8.0 may not work with the RHEL-8.1 beta. There seem to be
|
|
|
|
|
changes in dnf and zchunk which we have not worked out. This line will
|
|
|
|
|
be updated.

## Definitions
|
|
|
|
|
|
|
|
|
|
1. Package maintainer. Person who has accepted responsibility to
|
|
|
|
|
package and maintain software in the Fedora Project ecosystem. The
|
|
|
|
|
main packager is usually someone focused on Fedora Linux, and
|
|
|
|
|
secondary packagers may be focused on particular use cases like EPEL.
|
|
|
|
|
|
|
|
|
|
2. Consumer. A person who has subscribed to EPEL for packages but is
|
|
|
|
|
not a maintainer.
|
|
|
|
|
|
|
|
|
|
3. PDC. Product Definition Center. A tool to help list the lifetime
|
|
|
|
|
and permissions that a product has so that branching and updates can
|
|
|
|
|
be better managed.
