[Qemu-devel] [PULL 03/18] .travis.yml: separate tools and docs into another entry
Posted by Alex Bennée 5 years, 2 months ago
Re-building the tools and documents by default is a little wasteful as
they are not really affected by the main build options. Split tools
and documents into their own task with a minimal softmmu and
linux-user target list just to check they don't interact badly.

[Qemu-devel] [PULL 04/18] .travis.yml: fold --disable-tcg into alternate coroutine builds
Posted by Alex Bennée 5 years, 2 months ago
The alternate coroutine builds are really only of interest to people
running KVM (although I think you could use them for TCG if you really
tried). As they tend to run long lets kill two birds with one stone
and fold the --disable-tcg build into them.

[Qemu-devel] [PULL 08/18] tests: make docker.py update use configured binfmt path
Posted by Alex Bennée 5 years, 2 months ago
When copying a QEMU binary into a linux-user docker image we should
check what the current configured binfmt_misc path is rather than
just assuming "/usr/bin/qemu-bin". Obviously if the user changes the
configuration afterwards they will break their images again.

[Qemu-devel] [PULL 09/18] tests: make docker.py check for persistent configs
Posted by Alex Bennée 5 years, 2 months ago
binfmt_misc configured with the "F" flag opens the interpreter at
config time. This means it can use an already open file-descriptor to
run QEMU so there is no point trying to copy the binary into a
container.

[Qemu-devel] [PULL 10/18] tests: docker.py be even smarter with persistent binfmt_misc
Posted by Alex Bennée 5 years, 2 months ago
If we have a persistent mapping we don't need the QEMU binary copied
into the container as the kernel has already opened the file and will
pass the fd in. However the support libraries will still need to be
there.

[Qemu-devel] [PULL 11/18] tests: PEP8 cleanup of docker.py, mostly white space
Posted by Alex Bennée 5 years, 2 months ago
My editor keeps putting squiggly lines under a bunch of the python
lines to remind me how non-PEP8 compliant it is. Clean that up so it's
easier to spot new errors.

[Qemu-devel] [PULL 12/18] tests/vm: move images to $HOME/.cache/qemu-vm/images
Posted by Alex Bennée 5 years, 2 months ago
From: Gerd Hoffmann <kraxel@redhat.com>

It's easier to move around the images then, by replacing the
subdirectory with a symlink.  Allows to share the images between
multiple qemu checkouts for example.

[Qemu-devel] [PULL 17/18] docs/devel/testing: Add -a option to usermod command on docker setup
Posted by Alex Bennée 5 years, 2 months ago
From: Murilo Opsfelder Araujo <muriloo@linux.ibm.com>

The option -G of usermod command will remove user from other groups
not listed, i.e.: $USER will belong only to group 'docker' after
following the documentation as is.

From usermod(8) manual page:

    If the user is currently a member of a group which is not listed,
    the user will be removed from the group. This behaviour can be
    changed via the -a option, which appends the user to the current
    supplementary group list.

This patch improves the situation by adding the -a option to the
usermod command, which will just append user to the supplementary
group list.
