[ELN] Missing /usr/bin/bzr in ELN (solved, but open questions)

[Miro Hrončok <mhroncok@xxxxxxxxxx>]

Hello,

I've realized recently that the Python 3.9.0 final build failed in ELN:

python3.9-3.9.0-1.eln104:
https://koji.fedoraproject.org/koji/buildinfo?buildID=1620970

The build failure was:
  File 
"/tmp/tmpip_uvs06/pip-20.1.1-py2.py3-none-any.whl/pip/_vendor/toml/decoder.py", 
line 47
    TIME_RE = re.compile("([0-9]{2}):([0-9]{2}):([0-9]{2})(\.([0-9]{3,6}))?")
                         ^
SyntaxError: invalid escape sequence \.

I wondered why did this happen in ELN only and not in Rawhide.
The reason is: in Rawhide we have pip 20.2.2 which contains the fix of this problem.

So I investigated further and realized pip in ELN was not updated because the 
build is failing. The failure is:

    No matching package to install: '/usr/bin/bzr'

In Fedora, the executable is provided by breezy:

$ repoquery --repo=rawhide -l breezy | grep /usr/bin
/usr/bin/brz
/usr/bin/bzr
/usr/bin/bzr-receive-pack
/usr/bin/bzr-upload-pack
/usr/bin/git-remote-brz
/usr/bin/git-remote-bzr

However, breezy is not included in ELN at all:

$ repoquery --repo=eln-\* breezy
(nothing)

Despite the fact that it is in:
https://bodhi.fedoraproject.org/updates/FEDORA-2020-43fde95e1f

I can however see it in the ELN Koji buildroot:

$ repoquery --repo=kojieln breezy
breezy-0:3.0.2-4.eln103.x86_64

Yet it doesn't have the proper file:

$ repoquery --repo=kojieln -l breezy | grep /usr/bin
/usr/bin/brz
/usr/bin/bzr-receive-pack
/usr/bin/bzr-upload-pack
/usr/bin/git-remote-brz


I have discovered this is caused by a Fedora-only %if conditional in the spec file:

	
    # https://fedoraproject.org/wiki/Changes/ReplaceBazaarWithBreezy
    %if 0%{?fedora} >= 32
    %bcond_without replace_bzr
    %else
    %bcond_with replace_bzr
    %endif

I'll fix the conditional to make it RHEL-aware. However I have several questions:

1) Why is breezy not in the ELN compose, but is in the Koji buildroot?
2) As pip's maintainer, should I've been notified about the missing dependency?
3) When I fix breezy, should I resubmit the eln rebuilds of pip and Python?

Thanks,
