[Qemu-devel] [PATCH 0/6] Expand the building of qemu-user docker images

[Alex Bennée]

Hi Fam,

These are a little bit of a work in progress so maybe not all ready to
be taken yet although review would be welcome.

This adds some tweaks to allow us to build the cross-arch debian
images with direct make invocations and then see which images we can
test against from the "make docker" help text. Now:

  make docker-image-debian-stable-arm64

Will do exactly as you expect. I can't get:

  make docker-test-quick@debian-stable-arm64

To work but I suspect this needs some fixing to the generated rules.

Comments?

[Qemu-devel] [PATCH 1/6] tests/docker/Makefile.include: fix diff-index call

[Alex Bennée]

The whole thing is wrapped inside a call quiet-command as well as being
the actual call taking a --quiet argument so the redirect is
superfluous. For reasons I have yet to determine this also seems to be
causing the source preparation step to skip stashing work tree stuff.

[Qemu-devel] [PATCH 2/6] tests/docker/test-user: a simple linux-user test

[Alex Bennée]

This is useful for checking an appropriately updated cross-arch docker
actually starts without having to do a full build.

[Qemu-devel] [PATCH 3/6] tests/docker: add optional libs to travis.docker

[Alex Bennée]

In our .travis.yml we install a bunch of extra libraries which are not
part of the packaged QEMU's builddeps. We include them here to make our
docker container more closely match the state of the system after docker
has installed the rest of the build dependencies.

[Alex Bennée]

This allows you to create Debian images powered by a qemu linux-user
binary. Later patches will list these in the help file but for now:

  make docker-image-debian-stable-arm64

[Qemu-devel] [PATCH 5/6] tests/docker/docker.py: expand images command

[Alex Bennée]

Modern docker cli commands can filter by repository but as we want to
work on all instances do this by hand in python:

   /tests/docker/docker.py images --repo qemu

Will return a space delimited list for the benefit of our Makefile
recipes.

[Qemu-devel] [PATCH 6/6] tests/docker/Makefile.include: expand docker help text

[Alex Bennée]

No we can query what has and hasn't been built we can make this list
available in the help text. This is useful as some of the bootstrapped
builds can take some time to build.

Yep, I don't see the bug on my machine (Fedora 24, git 2.7.4). What about the
removed "--"? Does that make a difference for you?

Any reason to use two apt-get lines?

Also, can you put these package names in $PACKAGES and dump 'dpkg -l $PACKAGES'
to /packages.txt like in ubuntu.docker? That way we can print it in reports by
adding SHOW_ENV=1 in make invocation.

s/,/, /

Otherwise looks good.

I'm not sure how useful it is to list built images without checking if it's in
sync with the dockerfile: we still rebuild outdated ones even they're built.

Looks good, but what about binfmt_misc?

Currently the binfmt_misc check is done when the image is built (by the
pre script). We could expand docker.py to check and use that?

The -- seems superfluous as we are not giving it a list of files to
check against. I was seeing the problem with known files with changes
which were not committed.

My setup is Ubuntu 16.04 with git 2.10.1 (I track upstream stable).

I was just thinking that the real convenience only comes after the automated
setup of binfmt_misc (or a help text in "make docker" documentation).

What do you think?

Nope - it seems to be the &>/dev/null that triggers the problem - but
only in the Makefile. Running the commands from the command line works
as expected.

However why do we need the redirect here anyway considering the call
quiet-command?

It's to force suppressing output, while quiet-command only suppresses the
echoing of the command itself. Since we have "--quiet" here, does "2>/dev/null"
work for you?

That works!
