From: Johannes Schindelin <johannes.schindelin@gmx.de>

When this developer tested how the git-sdk-64-minimal artifact could be
served to all the GitHub workflow runs that need it, Azure Blobs looked
like a pretty good choice: it is reliable, fast and we already use it in
Git for Windows to serve components like OpenSSL, cURL, etc

It came as an unpleasant surprise just _how many_ times this artifact
was downloaded. It exploded the bandwidth to a point where the free tier
would no longer be enough, threatening to block other, essential Git for
Windows services.

Let's switch back to using the Build Artifacts of our trusty Azure
Pipeline for the time being.

To avoid unnecessary hammering of the Azure Pipeline artifacts, we use
the GitHub Action `actions/upload-artifact` in the `windows-build` job
and the GitHub Action `actions/download-artifact` in the `windows-test`
and `vs-test` jobs (the latter now depends on `windows-build` for that
reason, too).

    ci: avoid pounding on the poor ci-artifacts container
    
    I did not think through how I designed the Windows job initializing the
    minimal subset of Git for Windows' SDK (containing e.g. make, gcc etc):
    it currently accesses Azure Blobs and uses way too much bandwidth,
    blowing right through my quota.
    
    So for now, all the Windows/Visual Studio builds will be failing to
    download that SDK subset.
    
    With this patch, we use the (slower) method of downloading the
    git-sdk-64-minimal Build Artifact of our Azure Pipeline again, which
    fixes that particular problem.
    
    To be sure, it is a shame that we now spend around a whole minute
    downloading that SDK subset instead of those sweet, sweet seven seconds.
    But what does not work does not work, and that's that.

I guess this answers a question I sent earlier to the list (our
mails almost crossed, I guess, as two of us were looking at the same
problem at around the same time?).

Hopefully when cmake-for-windows-build topic lands, this can go away
altogether, but that is probably at least 8 weeks away (3 weeks
remaining before the next cycle opens, plus a half of 10 week per
cycle for a typical major release).

Today's final integration (these days I'm pushing out twice or three
times a day) contains this one, and it seems to have passed ;-)

Thanks.

Hi Dscho,

I wonder if it's acceptable to introduce jq (already installed in
GitHub Actions and Travis) into our codebase (only in GitHub Actions).

If yes, I think this will be easier to follow than depending on static
number of space and sed branching.

I am terribly sorry, but I did not get to read the Git mailing list at all
this week (or for that matter, my private mail). So I would not even have
seen your message... :-(

The `cmake-for-windows-build` would address only the build part for Visual
Studio. The regular Windows build, as well as the parallelized tests
_still_ need the `git-sdk-64-minimal` artifact. With or without CMake.
That's because neither CMake nor Visual Studio can accommodate the fact
that our test suite is implemented in shell script _and_ requires a
working Perl interpreter.

Excellent!

Thank you for that. Indeed, I should have checked whether `jq` is
available on the Windows build agents (and then I should have learned how
to hold that tool right).

I sent out a v2 with this change, and I already merged that version into
Git for Windows' `master` branch in preparation for v2.27.0-rc0.

Thanks,
Dscho
