[Qemu-devel] [PULL 01/23] docker: Handle exceptions when looking for docker command

[Fam Zheng]

From: Eduardo Habkost <ehabkost@redhat.com>

When trying to run docker tests on a host without the docker
command,  we get the following Python backtrace:

  $ make docker-test-quick@centos6 V=1
  .../qemu/tests/docker/docker.py build qemu:centos6 .../qemu/tests/docker/dockerfiles/centos6.docker
  Traceback (most recent call last):

      return args.cmdobj.run(args, argv)
    File ".../qemu/tests/docker/docker.py", line 231, in run
      dkr = Docker()
    File ".../qemu/tests/docker/docker.py", line 98, in __init__
      self._command = _guess_docker_command()
    File ".../qemu/tests/docker/docker.py", line 41, in _guess_docker_command

    File "/usr/lib64/python2.7/subprocess.py", line 523, in call
      return Popen(*popenargs, **kwargs).wait()
    File "/usr/lib64/python2.7/subprocess.py", line 711, in __init__
      errread, errwrite)
    File "/usr/lib64/python2.7/subprocess.py", line 1343, in _execute_child

  OSError: [Errno 2] No such file or directory
  .../qemu/tests/docker/Makefile.include:47: recipe for target 'docker-image-centos6' failed
  make: *** [docker-image-centos6] Error 1

Change _guess_docker_command() to handle OSError exceptions
raised by subprocess.call(), so we will keep looking for other
commands and print a better error message.

New output will be:

  $ make docker-test-quick@centos6 V=1
  .../qemu/tests/docker/docker.py build qemu:centos6 .../qemu/tests/docker/dockerfiles/centos6.docker
  Traceback (most recent call last):

[Qemu-devel] [PULL 02/23] util: Add UUID API

[Fam Zheng]

A number of different places across the code base use CONFIG_UUID. Some
of them are soft dependency, some are not built if libuuid is not
available, some come with dummy fallback, some throws runtime error.

It is hard to maintain, and hard to reason for users.

Since UUID is a simple standard with only a small number of operations,
it is cleaner to have a central support in libqemuutil. This patch adds
qemu_uuid_* functions that all uuid users in the code base can
rely on. Except for qemu_uuid_generate which is new code, all other
functions are just copy from existing fallbacks from other files.

Note that qemu_uuid_parse is moved without updating the function
signature to use QemuUUID, to keep this patch simple.

[Qemu-devel] [PULL 04/23] vhdx: Use QEMU UUID API

[Fam Zheng]

This removes our dependency to libuuid, so that the driver can always be
built.

Similar to how we handled data plane configure options, --enable-vhdx
and --disable-vhdx are also changed to a nop with a message saying it's
obsolete.

[Qemu-devel] [PULL 10/23] vl: Switch qemu_uuid to QemuUUID

[Fam Zheng]

Update all qemu_uuid users as well, especially get rid of the duplicated
low level g_strdup_printf, sscanf and snprintf calls with QEMU UUID API.

Since qemu_uuid_parse is quite tangled with qemu_uuid, its switching to
QemuUUID is done here too to keep everything in sync and avoid code
churn.

[Qemu-devel] [PULL 11/23] uuid: Tighten uuid parse

[Fam Zheng]

sscanf is relatively loose (tolerate) on some invalid formats that we
should fail instead of generating a wrong uuid structure, like with
whitespaces and short strings.

Add and use a helper function to first check the format.
