If we need to create a temporary directory in targetbuild or buildproject use
tempfile.TemporaryDirectory so that when the test case is finished, the
directory is deleted.
Also synchronise the logic and don't possibly store the temporary directory in
self.tmpdir as nothing uses that.

If runqemu fails it would leak an unclosed socket and file. Ensure we

Each time a runqemu() fails, the log handler would be left behind meaning
messages from any subsequent run would be duplicated (or worse/more).
This ensures we remove the handler regardless and means we no longer
have the duplication.

testimage.bbclass installs a SIGTERM handler which conflicts with the
use of multiprocessing here. This is paritcularly problematic if the http
service is terminated before its started and hence before its had a chance
to reset the default signal handler (as the code was written).
Instead, temporarily remove testimage's handler whilst forking the http process
which means the correct handler is installed and won't deadlock.
Also take the opportunity to add in some log messages about the server start
and shutdown so that future debugging is easier and its clearer what the code
is doing.

Similar to rpm, use copies of the ipk/deb directories for rootfs construction.
This means the image creation code can no longer "see" recipes wich aren't in its
dependency chain which is good for a variety of reasons including determinism,
incompatible recipe (e.g. systemd/sysvinit) package conflicts and locking

Currently do_rootfs gets to see all rpms in the deploy directory. This filters
that view to only rpms which the image recipe has actual depends upon which
potentially removes some sources of confusion in the image construction.
This makes builds more reproducibile and also fixes contamination issues

The current logging always assumes the boot timeout has expired yet

When debugging issues when timeouts are involved it is always best to
have wall clock times included. This helps give confidence that the
timeout is in fact run down at the right rate and that no unexpected
events were the true cause of a premature running down of the
timeout. Having these times in old logs also helps when debugging
issues as we have a historic record as to what is a 'typical' time to
complete an action.
In addition to adding the wall clock times the time to 'login' is now
printed making it consistent with the time to 'qemu pid'.

The logger handling in oeqa was confused at best. This patch:
a) Passes in a logger through various qemu runner pieces
b) Uses that logger consistently in the code
c) Creates a logger for QemuRunner outside the bitbake namespace
meaning we don't conflict with the tinfoil logging changes
The result of this is more consistency. For runtime tests in testimage,
the logs always contain the debug info, nothing is shwon on the console.
For the oe-selftests, logs are intercepted and only shown if the test
fails.

Python unittest intercepts stdout and stderr however qemurunner sets
up a streamhandler before that interception occurs, hence the messages
spam the unittest output.
By moving the logging init to the class init time, we use the unittest
stdout/stderr and this means unittest can only show the log output upon
failure. This cleans up the selftest and testimage output whilst still
showing logging upon failure.

Tests that use bitbake("my-test-image") can run for a long time
without any indication to the user of oe-selftest about what's going
on. The test author has to log the bitbake output explicitly,
otherwise it is lost in case of test failures.
Now it is possible to use bitbake("my-test-image",
output_log=self.logger) to get more output both on the console and in
the XML output (when xmlrunner is installed). Example output:
2017-06-23 12:23:14,144 - oe-selftest - INFO - Running tests...

Because the implementation was already using threading, the same is
done to decouple reading and writing the different pipes instead of
trying to multiplex IO in a single thread. Previously the helper
thread waited for command completion, now that is done in the main
thread.
The most common case (no input data, joined stdout/stderr) still uses
one extra thread and a single read(), so performance should be roughly
the same as before.
Probably unintentionally, result.error was left as byte string when
migrating to Python3. OE-core doesn't seem to use runCmd() with split
output at the moment, so changing result.error to be treated the same
as result.output (i.e. decoded to a normal strings) seems like a
relatively safe API change (or rather, implementation fix).

Change all callers of subprocess.call() which do not check for
the return value to use subprocess.check_call() which raises
CalledProcessError if the subprocess returns with non-zero value.

That a utility function permanently changes the process environment is
bad style and leads to subtle, hard to debug problems.
For example, we had one oe-selftest which used runqemu() with an
override for DEPLOY_DIR_IMAGE. Another test then just called runCmd()
and ended up passing the wrong DEPLOY_DIR_IMAGE set earlier in
os.environ.
The approach used here is to pass the desired environment dict to the
launch() method as a new, optional parameter, which then gets passed
on to subproject.Popen(). The modified env variables do not get
logged, as before.

By default, QemuRunner avoids modifying the image files that it boots
into by enabling the qemu snapshot mode. However, some tests may want
to test changes that must persists across reboots, so this mode
should be optional.
This can be combined by copying the image file to a temporary location
first and then booting with that copy. It's also useful when testing
with additional drives attached to a virtual machine.
QemuTinyRunner doesn't use the snapshot parameter and therefore ignores
the new parameter.
Long term, a better way of passing these various configuration
parameters should be used, and perhaps QemuRunner and QemuTinyRunner
can be merged into one again to avoid code duplication. But for now
the patch follows the exiting style.
Also beware that QemuTarget.start() now acts in two different modes
(with or without explicit launch command), and depending on that mode
parameters like discard_writes must be ignored, i.e. not get passed to
launch().

runqemu() takes all parameters for the virtual machine from the
variables of the given recipe. By allowing the caller to provide a
hash with variables that get applied locally, the caller gets more
control.
Here's the intended usage:
<prepare internal-image in self.resultdir>
overrides = {
'DEPLOY_DIR_IMAGE': self.resultdir,
'IMAGE_LINK_NAME': 'internal-image-%s' % self.image_arch,
}
with runqemu('refkit-installer-image', ssh=False,
overrides=overrides) as qemu:
....
This can be used to replace the image completely with something else
or to copy it before allowing runqemu() to write into it.

Sometimes it is useful to reconfigure the qemu virtual machine
directly. runqemu has the "qemuparams" parameter for that, and the
underlying start() methods also supported modifying that via their
"params" parameter. Only the runqemu() wrapper function lacked

One potential usage is to attach additional disks.

Sometimes, the OEQA utility code aborts with:

return self.launch(launch_cmd, qemuparams=qemuparams, get_ip=get_ip, extra_bootparams=extra_bootparams)
File ".../meta/lib/oeqa/utils/qemurunner.py", line 259, in launch
sread, swrite, serror = select.select(socklist, [], [], 5)
InterruptedError: [Errno 4] Interrupted system call
strace shows that this is because of a SIGWINCH:
Connection from 127.0.0.1:52668
select(21, [20], [], [], {5, 0}) = ? ERESTARTNOHAND (To be restarted if no handler)
--- SIGWINCH {si_signo=SIGWINCH, si_code=SI_KERNEL} ---
This is related to some special conditions:
* whether qemu opens a graphical console window (enabled in Poky by default)
* where that window gets opened
* whether the window manager changes the size of the shell window (mine
is a tiling window manager and reorders and resizes windows automatically)
Ignoring the interrupted system calls avoids the problem. Code elsewhere (for example,
run() in ssh.py) already does the same thing.
