Is Koschei using CentOS 7 in the EPEL 7 resolve check?

[Miro Hrončok]

See for example:

https://apps.fedoraproject.org/koschei/package/python-mccabe?collection=epel...
2019-08-11 07:50:11

- nothing provides python(abi) = 3.6 ...

This is provided in RHEL 7.7.

(Note that we've unretired the python36 package, so later it resolved correctly.)

[Igor Gnatenko]

I think it uses koji build repo. So same as epel buildroot does.

If it helps Copr (and mock) use centos 7 [1]

Koschei uses Koji repos. You can find out the exact repo URL at given
timestamp in the following way:

In [1]: import koji, datetime
In [2]: ks = koji.ClientSession('https://koji.fedoraproject.org/kojihub')
In [3]: pi = koji.PathInfo('https://kojipkgs.fedoraproject.org')
In [4]: ts = datetime.datetime(2019,8,11,8,8,10).timestamp()
In [5]: event = ks.getLastEvent(before=ts)
In [6]: repo = ks.getRepo(tag='epel7-build', state=koji.REPO_READY,
event=event['id'])
In [7]: pi.repo(repo['id'], 'epel7-build')
Out[7]: 'https://kojipkgs.fedoraproject.org/repos/epel7-build/1234463'

x86_64 repos are used for dependency resolution. At that time python36
was not available in epel7-build:

$ dnf -q --repofrompath
epel7-build-1234463,https://kojipkgs.fedoraproject.org/repos/epel7-build/1234463/x86_64/
--repo epel7-build-1234463 repoquery --whatprovides 'python(abi)'
python-0:2.7.5-80.el7_6.x86_64
python34-0:3.4.10-2.el7.x86_64

And for RHEL packages?

Are RHEL packages available directly from epel7-build?

Selected RHEL packages are available in EPEL buildroots.

Yes, they are. Eg python-0:2.7.5-80.el7_6.x86_64 from my example is a
RHEL build.

Oh. Do you know any pointers about how do I add more?

EPEL 7 build uses repos from 5 RHEL 7 channels.
You can see them with the following command:

$ koji list-external-repos --tag epel7-base
Pri External repo name        Mode       URL
--- ------------------------- ----------
----------------------------------------
10  rhel7-server              koji
http://kojipkgs.fedoraproject.org/repo/rhel/rhel7/$arch/rhel-7-server-rpms/
11  rhel7-rhel-extras         koji
http://kojipkgs.fedoraproject.org/repo/rhel/rhel7/$arch/rhel-7-server-extras...
12  rhel7-server-ha           koji
http://kojipkgs.fedoraproject.org/repo/rhel/rhel7/$arch/rhel-ha-for-rhel-7-s...
15  rhel7-server-optional     koji
http://kojipkgs.fedoraproject.org/repo/rhel/rhel7/$arch/rhel-7-server-option...
20  rhel7-server-rhscl-7      koji
http://kojipkgs.fedoraproject.org/repo/rhel/rhel7/$arch/rhel-server-rhscl-7-...

Koji admins (i.e. Release Engineering) can add more channels upon
request from EPEL developers.
Before adding to Koji, RHEL repos would need to be synced from RHN to
Fedora servers (this can be requested from Fedora Infrastructure).
