Libvirt uses GitHub as an automated read-only mirror. The goals were to
have a disaster recovery backup for libvirt.org, a way to make it easy
for people to clone their own private copy of libvirt Git, and finally
as a way to interact with apps like Travis.

The project description was set to a message telling people that we
don't respond to pull requests. This was quite a negative message to
potential contributors, and also did not give them any guidance about
the right way to submit to libvirt. Many also missed the description and
submitted issues or pull requests regardless.

It is possible to disable the issue tracker in GitHub, but there is no
way to disable merge requests. Disabling the issue tracker would also
leave the problem of users not being given any positive information
about where they should be reporting instead.

There is a fairly new 3rd party application built for GitHub that
provides a bot which auto-responds to both issues and merge requests,
closing and locking them, with a arbitrary comment:

   https://github.com/apps/repo-lockdown

This commit adds a suitable configuration file for libvirt, which
tries to give a positive response to user's issue/pullreq and guide
them to the desired contribution path on GitLab.

FYI, I have configured the test.git repo to demonstrate the operation.

See the comments / actions performed here:

  https://github.com/libvirt/test/pull/3
  https://github.com/libvirt/test/issues/2

This lockdown.yml file will need to be created in each libvirt git
repo, with just the URL changed. If this patch is approved, then I
propose to directly push the equivalent config file to every other
git repo, without spamming libvir-list for review of each.

Ideally we should be creating a CONTRIBUTING.md file in each repo
too, as both GitHub and GitLab direct users to look at this file
for information about how to contribute. This is how we could
guide people to use GitLab in the first place, avoiding them
filing issues/pulls on the wrong site and triggering this bot.

The content here is treated as literal markdown, with line breaks
preserved. If I line wrap it here, then it gets line wrapped when
displayed to the user which is not desirable - I want to let the
browser wrap according to the space it has to display the comment.

Using ">" instead of "|" for the multiple line string lets you
do wrapping, which is then ignored, but this has the annoying
side effect of also removing the blank lines between paragraphs.

So the long lines were the least worst option to give the desired
display in the browser that I came up with.

Maybe s/merge/pull/ here? Since we're adding a comment on GitHub and
targeting GitHub users when doing so, it might be more appropriate to
use the GitHub term.

Everything else looks good, but there's the obvious caveat that we
can't merge the commit as-is until we have actually moved to GitLab.

Since that could take a while, and locking down the GitHub
repositories is already a good idea, maybe point people to

  https://libvirt.org/hacking.html

in the meantime?

As danpb mentions in the cover letter, CONTRIBUTING.md should be easily
discoverable on GitLab. We [0] should somehow put the brief instructions
there (like README-hacking) and not scare drive-by contributors with
the giant hacking.html.

OTOH, I'm not sure how well 'I fixed these coding styles issues and
pushed the patch' translates to the merge request review.

Jano

[0] it's on my TODO list (TM)

The problem with hacking.html is that it's a catch-all location that
where a hodgepodge of concepts, which are related to various degrees,
are documented:

  * various resources related to libvirt development, such as the
    primary git repository and the libvirt project on Zanata;
  * how to write good commit messages;
  * how to split changes into multiple commits;
  * other requirements, such as having DCO information;
  * how to run the test suite;
  * how to fix issues reported by valgrind;
  * how to send patches to libvir-list;
  * which languages are appropriate for new code;
  * what's our code style;
  * which GLib APIs should be used instead of libvirt-specific APIs
    that in most cases have been dropped already;
  * governance rules;

all of it sprinkled with useful tips such as which options to use
when running 'git diff'. No wonder it's overwhelming.

I think we should rethink how we organize this information. For
example, while the fact that git-publish should be used to post
patches is, at least until we complete the move to GitLab, critical
information to new contributors, but detailed steps for setting up
mail delivery in git could live in a separate guide linked to from
the main document, so that only those who are not already familiar
with a mail-based development workflow need to access it; along the
same line, how to run the test suite should be documented prominently
but how to solve issues reported by valgrind doesn't.

Of course the biggest offender is the coding style, which takes up
most of the page. That could be split off to a separate page too,
under the IMHO sane assumption that even someone unfamiliar with the
codebase will naturally get very close to adhering to it through a
combination of looking at existing code and addressing the issues
reported by 'make syntax-check'; in the longer run, we should really
invest some time building a clang-format profile that approximate
our current coding style and just require that all contributions
go through that tool, thus making the page mostly obsolete.

Anyway, back to CONTRIBUTING.md specifically: once we have improved
and trimmed down hacking.html (contributing.html?) to a reasonable
size, we can simply link to it. I don't think that's a strict
dependency, however, and while our current hacking.html is clearly
suboptimal I'd rather have issues/PRs locked down and directing
developers to it than the current status quo.

I don't think it does. However, once syntax-check is something that
is run automatically at MR time and which gates merge, contributors
are more likely to address the issue themselves before a reviewer
gets around to looking at the changes.

IMHO the CONTRIBUTING.md is something that can be fairly simple. The
important things is that it should cover directly are

 - How to submit patches
 - How to report issues
 - How to comply with the DCO

Then it should provide links to information about coding style,
information around testing, information about platform portability
expectations, and other important reference material that might be
relevant.

We can certainly split up / re-organize hacking.html more generally,
but I don't think that's a strict pre-requisite for adding a simple
CONTRIBUTING.md file.

Daniel

I'll try to give this a shot.

I'm wary of the risk of duplicating information in multiple places.

We already have some overlapping information between hacking.html
and README-hacking, but that's justified by the fact that it was
considered a good idea to provide "bootstrap" steps, ie. enough
information to get to the point where you could build the full HTML
documentation locally from a git clone. I'm no longer convinced this
is that useful, because if you have a git clone you clearly have
internet access and at that point you might as well jump straight to
the pre-built version available on libvirt.org, but let's leave this
argument for another day.

What we do *not* want to have is another "quick start guide" that
duplicates the information further. If our hacking.html is too
overwhelming to serve as such a landing page, then we should change
it so that it no longer is, not add yet another overlapping document.

Now that we've got the release out of the way, I want to do the switch
to GitLab as the master repository in the next day or two. I've got
everything prepared that we need now I believe. Must just flip the repo
mirror job into reverse and make the old repos read-only to current
maintainers to prevent acceidental pushes to the wrong place. I'll plan
to do this on Tuesday, approx 1200 GMT give/take an hour.  Maintainers
will merely need to update their git origin URL, nothing more.

Although this lockdown message suggests opening a merge request, and
we wouldn't immediately be using merge requests for libvirt.git, I
dont think that's a problem. The number of people who'll see and follow
this lockdown message is going to be pretty small to start with at least,
so its not a big deal if we tell them to use MR right now.

That's fair, but even for those few people why wouldn't we point
them to the current documentation for the time being and only start
pointing them to GitLab merge requests once we actually move to that
workflow?

I think that's just unnecessary churn, with no real benefit, especially
since this lockdown will be replicated across all the repos.

I disagree, but on the other hand I *do* agree that this is likely
to only hit a very small population, so I won't stand in the way.
