GitHub now allows users to subscribe only to
"release" notifications of a repository.
So, users can be notified of new releases and their
changelog/release notes automatically.

This workflow works whenever:
    a new version tag
    (with the format following the regex "v\d+\..*")
    is pushed to the repository
AND
    the commit that the tag points to, created/modified
    a release notes file from Doumentation/RelNotes/ directory.

The script for generating the temporary changelog file is
written in Kotlin language which can be a much better alternative
to shell scripts in terms of features and readability
(it is like a python script but with static typing support).
The Kotlin runner is pre-installed in GitHub Actions environments;
for more information see
    https://github.com/actions/virtual-environments/
    https://stackoverflow.com/a/69116750/8583692

The "Release Notes (yyyy-MM-dd)" link in https://git-scm.com/
website can also link to these GitHub release pages instead of
to the raw .txt release note file in the repository.

See the issue related to GitHub release notifications:
https://github.com/isaacs/github/issues/410

    Add a workflow for creating GitHub release notes
    
    Because this is not directly the git code and is related to GitHub CI, I
    post it here.
    
    This pull request adds a new GitHub Actions workflow that automatically
    creates releases on GitHub repository when pushing a new tag to the
    repository.

Hi Mahdi,

I've already written up these concerns on GitHub [1] and you've replied 
there, but Johannes asked me to also send this to the mailing list, so 
please bear with me for mostly repeating the same points.

Nit: "Github now allows users" sounds like a new feature, not one that's 
three years old.

We need to spin up a JVM for 21 lines of code just to copy a single 
file. I think a single call of `cp` is faster and more readable than that.

I think we should probably exclude the release candidates from this. As 
Johhannes pointed out[2], marking them as full releases would 
periodically cause https://github.com/git/git/releases/latest to point
to a pre-release instead of the latest full release.

The value 2 seems pretty arbitrary and the comment adds nothing.

You've replied on Github that you need the last two commits for this 
action [3], but I don't think we care about wether or not the release 
notes where changed in the last commit. We only need the version number 
(from the pushed tag) to determine the correct release notes file.

If we just use the file directly we don't even need to copy the file to 
changelog.txt

If we don't exclude release candidates, we should set prelease to true for 
those tags.

All in all I think this is too convoluted for what it's trying to 
achieve. I think we should be able to achieve the same result with 
something like this:

An example of the result this reduced action produces can be found at [4] 
(release notes for v2.34.1, but the tagged commit isn't v2.34.1).

One thing I had not thought of earlier: do we really want to do this in
every fork of git/git? I know for a fact that microsoft/git has a very
different workflow upon pushing a tag.

So maybe we need something like this, too:

   create-gh-release:
+    if: github.repository == 'git/git'
     name: Create a new release or update an existing release in the GitHub repository

Ciao,
Dscho

I think you're right. This would have unidesirable side effects if it ran 
in forks.

Rather than hardcode given repositories, which e.g. for testing the CI
itself can be bothersome, perhaps a better thing is to put this into the
existing ci-config? I.e. git/git.git could opt itself in to behavior
that would be off by default?

I don't know how much that matters in this case, but I don't see why
we'd hardcode repository paths in general since we've got the ci-config.

You probably missed that the purpose of this workflow is something that
does not make sense in the forks of git.git.

Its purpose is to create releases for all tags that are pushed to the
repository. Most forks of git.git have no business creating releases, and
those that do already have their own processes in place.

As such, the situation is very different from the CI/PR runs that some
contributors might want to restrict to only certain branches in their
forks.

Integrating it into `ci-config` is not even possible in this instance
because the newly-introduced workflows should only ever run on tags, while
the `ci-config` step is part of a workflow that needs to run on every new
push and PR.

Those are two very, very different things. So even if it would have made
sense to use `ci-config` in the workflow under discussion, it is not
applicable because that step lives in a different workflow that is
triggered for a different set of events.

Ciao,
Johannes

All true.  But https://github.com/git/git/ itself has no business
creating releases, as we already have the release process that
pushes the release material to kernel.org to be distributed from
there.

So... do we still need to discuss this patch?  In other words,
what's the benefit of creating "releases for all tags that are
pushed to the repository" there?  Does it give us redundancy in case
kernel.org goes down?  Does it risk confusing users having to wonder
release materials from which source is more "genuine"?

One benefit that I see is that github offers APIs & Notifications around 
releases and lots of CI integration already exist for it. If my (non github) 
CI includes building the git source then i can easily trigger when upstream 
releases a new version. Just pulling the repo and watching for the tag works 
just as well of course.

However the "which source is genuine" is a valid objection. You certainly 
don't want the CI to accidentally create a new release that does not exist 
on kernel.org (yet).

Ahh, thanks.

If some sort of "push" notification is available only for "there is
a new release" but not for "there is a new tag", then I can sort of
see why having a "release" would be nice.  Listening to notifications
and acting on them is more pleasant than having to poll.

Do I understand what you said correctly?

Yes, thats correct. 

Github has a webhook for releases:
https://docs.github.com/en/developers/webhooks-and-events/webhooks/webhook-events-and-payloads#release

Getting tags means listening to every push and filtering yourself:
https://docs.github.com/en/developers/webhooks-and-events/webhooks/webhook-events-and-payloads#push

Still, if this gets added to git/git I think the risk of users considering 
the github release to be the primary source is quite high since lots of 
tools and CI integrations use them. I'm not a fan of depending on github for 
everything, but as long as the kernel.org releases don't go away I don't 
think this is a big deal.
