We've seeing issues where IO load appears to cause strange failures due to timeouts
within qemu. One theory for these is that it is is hitting hard page faults
at in-opportune moments which cause timing problems within the VM.
This patch is a bit of a hack which tries to ensure the data is paged in
at a point when we know we can take the time delays (waiting for the QMP
start signal). Whilst this isn't ideal, it does seem to improve things on
the autobuilder and shouldn't harm anything.
The code figures out which files to read my looking at the mmap'd files
the process has open from /proc. On Centos7 systems these files are not
user readable, if that is the case we just skip them.

Rather than totally disabling the logging, inform it we're about to exit
so we can log messages over the exit cleanly too. This aids debugging. It
also avoids a race where the logging handler could still error whilst
shutting down.
Also remove a race window by notificing the handler of the shutdown
first, before triggering it. This removes a race window I watched in

This adds support for the Qemu Machine Protocol [0] extending
the current dump process for Host and Target. The commands are
added in the testimage.bbclass.
Currently, we setup qemu to stall until qmp gets connected and
sends the initialization and continue commands, this works
correctly. If the UNIX Socket does not exist, we wait an timeout
to ensure to socket file is created.
With this version, the monitor_dumper is created in OEQemuTarget
but then set in OESSHTarget as that's where we get the SSH failure
happens. Python's @property is used to create a setter/getter type
of setup in OESSHTarget to get overridden by OEQemuTarget.
By default the data is currently dumped to files for each command in
TMPDIR/log/runtime-hostdump/<date>_qmp/unknown_<seq>_qemu_monitor as
this is the naming convenstion in the dump.py code.
We use the qmp.py from qemu, which needs to get installed in the
recipe-sysroot-native of the target image.

We have a working theory that IO queues on the autobuilder are impacting
runtime testing under qemu, particularly async writes which inice does not
influence. We already pass the snapshot option to qemu which copies the
image and runs out of the copy. Add in the ability to copy the image to
a specificed location which can be a tmpfs. This means that writes to the
image would no longer be blocked by other writes to disk in the system.
Preliminary tests show that this does improve the qemu errors at the expense
of sometimes showing qemu startup timeouts as on a loaded system with a large
test image, it can take longer than 120s to copy the image to tmpfs. Having
a most consistent failure mode for loaded tests is probably desireable though.

Increase the serial login timeout from 60 to 120s. This seems like a
long time, however for a qemumips image with systemd+PAM and openssh,
(e.g. core-image-sato-sdk + DISTRO=poky-altcfg), the getty connects
to systemd's pam module which waits on logind and 45s for all this
to happen at the same time as things like ssh key generation happens
is not unknown.
Increase the timeout to match the longer times we know these things
can take in the worst case scenarios since we're tired of intermittent
issues related to the serial login affecting the autobuilder.

Occasionally we've been seeing leftover threads from runCmd. The stdin test
assumes we clean up all threads but the code assumes that the daemonic thread
can be left behind.
The issue can be reproduced by adding a time.sleep(10) to the end of
writeThread() which will mean it stays resident past the end of the command.
We may as well add it to the threads list and clean it up properly,
hopefully removing the race in the tests from the autobuilder.

The current runtime infrastructure contains hardcoded values which Ill refer to
as patterns, these patterns are either searched through or sent via the serial
terminal to communicate between HOST and TARGET.
These patterns are required since they allow us to check when a device has
finished booting, to log in, and to check whether a command sent from our tests
has returned, this way we are able to check both the status of the commands that
were sent along with its output.
The testing process goes somewhat as follows:
1. Launch QEMU and start booting.
2. Check when the device has booted by looking for the pattern login:.
3. Log in as the root user (default for our images).
4. Check that we were able to log in succesfully.
5. Start running the runtime test cases defined by TEST_SUITES.
6. One of such test cases could send a command to the QEMU target.
7. Check whether that command returned.
8. Check its output and status, return whether the test case passed or failed.
This patch allows this set of patterns to be defined instead of being hardcoded,
but it also automatically sets the defaults that we have been using in the past
if they have not been manually defined, for this reason, the patch is less
invasive and should not affect in any way how tests are currently being run.
Cases that can be enabled with this patch:
- A customized image that does not use the root user (or maybe we want to check
what happens if we dont use the root user).
- An image where the PS1 env variable has been modified, and the prompt pattern
wouldnt match the default.
- Baremetal applications, which do not follow the conventional way of booting
Linux and would probably not show a prompt for a user to log in, same applies
for testing bootloaders.
- poky-tiny: Using DISTRO=poky-tiny and an image such as the core-image-tiny
from meta-intel, which boots directly to RAM, and does not show a log in prompt
since it does not contain a conventional init process.
The code itself contains comments that should be self explanatory but here is an
example on how these patterns can be defined in a hypothetical case where we
want to run test cases as the webserver user instead:
TESTIMAGE_BOOT_PATTERNS = "send_login_user search_login_succeeded"
TESTIMAGE_BOOT_PATTERNS[send_login_user] = "webserver\n"
TESTIMAGE_BOOT_PATTERNS[search_login_succeeded] = "webserver@[a-zA-Z0-9\-]+:~#"
The variable TESTIMAGE_BOOT_PATTERNS defines which patterns to override when
used to communicate with the target when booting, anyone familiar with the
PACKAGECONFIG syntax should have no trouble setting these.
Other patterns would still be set up as default, e.g.
search_reached_prompt would still be login:
The accepted flags for TESTIMAGE_BOOT_PATTERNS are the following:
search_reached_prompt, send_login_user, search_login_succeeded,
search_cmd_finished.
They are prefixed with either search/send, to differentiate if the pattern is
meant to be sent or searched to/from the target terminal.
A working example of this code that falls under the baremetal case mentioned
above along with a test case is present on the meta-freertos layer, which tests
an RTOS image built with OpenEmbedded and automatically runs a test case on it
after booting such image:
As usual, INHERIT += "testimage" needs to be present on local.conf
