Hi!

Slavek, thanks for a thorough email.

Hmm, I don't follow how this would mean creating Koji from Copr. For
example, Koji doesn't handle things like SCM, pull requests, inline code
comments, lightweight issue tracking?

Hmm, who is people? Where do you get this impression from?
In my opinion, GitHub's popularity speaks against that.

I think fedorahosted.org has many drawbacks, which is demonstrated by
its unpopularity. Of course, it would be great to work on improving
fedorahosted.org and bring it back to being state-of-the-art for project
hosting, but this will likely take a lot of time.
Hence, I think it would be easier and faster to create a "thin
GitHub-like" layer on top of COPR.

This would be another possible alternative to building a "thin
GitHub-like" layer on top of COPR.

Yes, that could also work.

In relation to the "Fedora ugly" repo, we have to think about where to
put the functionality that would enable a packager's workflow to include
his package/repo in the "Fedora ugly" repo.
I'm thinking of things like:
1) propose a package/repo for inclusion
2) get the results of the automatic review
2a) get help with the items that didn't pass review
2b) report a problem in the automatic package review
3) update the approved package in the "Fedora ugly" repo
4) add a co-maintainer of the package in the "Fedora ugly" repo
5) pull a package/repo from the "Fedora ugly" repo

Would we put this into COPR, tool like Tito or this "thin GitHub-like"
layer on top of COPR?

(I haven't heard of Tito before, so thanks for the pointer!)

Like you said, fedorahosted.org feels clumsy and out-dated. See also my
point above.

This way, we would be able to track the repo that srpm came from and the commit hash - again, this would improve the experience for potential contributors, who would be able to easily find where to send pull requests/patches.

+1. And it's not just about scaring potential Fedora contributors. We
want to make package maintenance as easy and automated as we can to
lessen the burden of existing packagers.

> Also, having git repos would IMO significantly improve the possibilities of collaboration and tracking - compared to throwing bunch of srpms into Copr by hand.

+1.

> I don't think that we necessarily need to provide the hosting for this, but we should definitely provide a howto guide that would describe how to _easily_ achieve this with e.g. Github/Bitbucket repos and so on.

This is an important point. If we decide that it is ok to rely on
external project hosting services like GitHub/Bitbucket, we get all of
the benefits of their work-flow for free, minus the drawbacks of using
such heterogeneous services (e.g. distinct user interfaces).

I put "if we decide it is ok" since relying on external hosting bring
some questions (I'll use GitHub in the questions, but any GitHub-like
external service has the same issues):
- How do we deal with cases when a user, who is no longer interested in
his package/repo, deletes it from GitHub? Will we host private git
mirrors of external git repos for such cases?
- The transition to the Fedora "Collection" (i.e. main repo) will be
seen as a step back-wards with respect to the work-flow that GitHub
enables. Will we allow packages that went under proper (old style)
review to use GitHub for SCM?
- How do handle the downtime of GitHub? Or what to do if they, for some
unknown reason, change their policy to start charging for using/viewing
it? ...


> Again, we should show an easy way for potential contributors, who may enter Fedora by building in Copr.

+1.

Tadej
