Emanuele Giuseppe Esposito 87e4d4a205 pylint: fix errors and warnings generated by tests/qemu-iotests/297
Test 297 in tests/qemu-iotests currently fails: pylint has
learned new things to check, or we simply missed them.

All fixes in this patch are related to additional spaces used
or wrong indentation. No functional change intended.

Emanuele Giuseppe Esposito eb7a91d07a qemu-iotests: add option to show qemu binary logs on stdout
Using the flag -p, allow the qemu binary to print to stdout.

Also create the common function _close_qemu_log_file() to
avoid accessing machine.py private fields directly and have

Emanuele Giuseppe Esposito a9b4c6bb64 qemu-iotests: extend the check script to prepare supporting valgrind for python tests
Currently, the check script only parses the option and sets the
VALGRIND_QEMU environmental variable to "y".
Add another local python variable that prepares the command line,
identical to the one provided in the test scripts.

Because the python script does not know in advance the valgrind
PID to assign to the log file name, use the "%p" flag in valgrind
log file name that automatically puts the process PID at runtime.

Paolo Bonzini 480b75ee14 qemu-iotests: let "check" spawn an arbitrary test command
Right now there is no easy way for "check" to print a reproducer command.
Because such a reproducer command line would be huge, we can instead teach
check to start a command of our choice.  This can be for example a Python
unit test with arguments to only run a specific subtest.

Move the trailing empty line to print_env(), since it always looks better
and one caller was not adding it.

Vladimir Sementsov-Ogievskiy f203080bbd iotests: rewrite check into python
Just use classes introduced in previous three commits. Behavior
difference is described in these three commits.

Drop group file, as it becomes unused.

Drop common.env: now check is in python, and for tests we use same
python interpreter that runs the check itself. Use build environment
PYTHON in check-block instead, to keep "make check" use the same
python.

Checking for virtio-blk moved to iotests.py, as it actually iotests.py
dependency. Actually not all python iotests depend on it, so in future
it may be refactored to checked only when really needed.

Kevin Wolf b1cbc33a39 iotests: Allow running from different directory
It is convenient to be able to edit the tests and run them without
changing the current working directory back and forth. Instead of
assuming that $PWD is the qemu-iotests build directory, derive the build
directory from the executed script.

This allows 'check' to find the required files even when called from
another directory. The scratch directory will still be in the current
working directory.

Thomas Huth cd2058289b iotests: Skip Python-based tests if QEMU does not support virtio-blk
We are going to enable some of the python-based tests in the "auto" group,
and these tests require virtio-blk to work properly. Running iotests
without virtio-blk likely does not make too much sense anyway, so instead
of adding a check for the availability of virtio-blk to each and every
test (which does not sound very appealing), let's rather add a check for
this a central spot in the "check" script instead (so that it is still
possible to run "make check" for qemu-system-tricore for example).

Max Reitz c7df3f19d2 iotests: Introduce $SOCK_DIR
Unix sockets generally have a maximum path length.  Depending on your
$TEST_DIR, it may be exceeded and then all tests that create and use
Unix sockets there may fail.

Circumvent this by adding a new scratch directory specifically for
Unix socket files.  It defaults to a temporary directory (mktemp -d)
that is completely removed after the iotests are done.

(By default, mktemp -d creates a /tmp/tmp.XXXXXXXXXX directory, which
should be short enough for our use cases.)

Use mkdir -p to create the directory (because it seems right), and do
the same for $TEST_DIR (because there is no reason for that to be
created in any different way).

Andrey Shinkevich 57ed557f03 iotests: ask QEMU for supported formats
Supported formats listed by 'qemu' may differ from those listed by
'qemu-img' due to whitelists. Some test cases require specific formats
that may be used with qemu. They can be inquired directly by running
'qemu -drive format=help'. The response takes whitelists into account.
The method supported_formats() serves for that. The method decorator
skip_if_unsupported() checks if all requested formats are whitelisted.
If not, the test case will be skipped. That has been implemented in
the 'check' file in the way similar to the 'test notrun' mechanism.

POSIX requires $PWD to be reliable, and we expect all

So replace it with the following:

sed -i 's/\(`pwd`\|\$(pwd)\)/$PWD/g' $(git grep -l pwd)

Then delete a pointless line assigning PWD to itself.

Lukáš Doktor 96914159b7 qemu-iotests: Use ppc64 qemu_arch on ppc64le host
The qemu target does not always correspond to the host machine type. For
example ppc64le machine target is ppc64. Let's introduce "qemu_arch"
variable to store the matching qemu architecture related to the current
architecture and use it when auto-detecting the default qemu binary.

Eric Blake 63ca8406be iotests: Avoid realpath, for CentOS 6
CentOS 6 lacks a realpath binary on the base install, which makes
all iotests runs fail since the 2.11 release:

001         - output mismatch (see 001.out.bad)
./check: line 815: realpath: command not found
diff: missing operand after `/home/dummy/qemu/tests/qemu-iotests/001.out'
diff: Try `diff --help' for more information.

Many of the uses of 'realpath' in the check script were being
used on the output of 'type -p' - but that is already an
absolute file name.  While a canonical name can often be
shorter (realpath gets rid of /../), it can also be longer (due
to symlink expansion); and we really don't care if the name is
canonical, merely that it was an executable file with an
absolute path.  These were broken in commit cceaf1db.

The remaining use of realpath was to convert a possibly relative
filename into an absolute one before calling diff to make it
easier to copy-and-paste the filename for moving the .bad file
into place as the new reference file even when running iotests
out-of-tree (see commit 93e53fb6), but $PWD can achieve the same
purpose.

Kevin Wolf e1473133f7 qemu-iotests: Enable write tests for parallels
Originally we added parallels as a read-only format to qemu-iotests
where we did just some tests with a binary image. Since then, write and
image creation support has been added to the driver, so we can now
enable it in _supported_fmt generic.

The driver doesn't support migration yet, though, so we need to add it
to the list of exceptions in 181.

Eric Blake 8803714b53 iotests: Restore stty settings on completion
Executing qemu with a terminal as stdin will temporarily alter stty
settings on that terminal (for example, disabling echo), because of
how we run both the monitor and any multiplexing with guest input.
Normally, qemu restores the original settings on exit; but if an
iotest triggers qemu to abort in the middle, we can be left with
the altered terminal setup.  This can make life very annoying when
debugging an iotest failure (not everyone remembers the trick of
blind-typing 'stty sane' without echo, and some people prefer
terminal settings that are slightly different than the defaults
picked by 'stty sane').

It is possible to avoid qemu corrupting the terminal by not passing
a terminal to qemu's stdin in the first place (as in, use
'./check ... </dev/null'), but that's extra typing to have to
remember.  But running 'exec </dev/null' in the harness seems like
it might be too heavy of a hammer.  So I instead went the the
solution of saving and restoring the stty settings, only when the
harness detects that it is run interactively.

I tested this patch by forcing an allocation failure (I can't
guarantee that this particular limit will work on all setups, but
it shows the idea):
 $ (ulimit -S -v 500000; ./check -qcow2 1)

Paolo Bonzini cceaf1db6f qemu-iotests: cleanup and fix search for programs
Instead of ./check failing when a binary is missing, we try each test
case now and each one fails with tons of test case diffs.  Also, all the
variables were initialized by "check" prior to "common" being sourced,
and then (uselessly) checked for emptiness again in "check".

Centralize the search for programs in "common" (which will soon be
one with "check"), including the "realpath" invocation which can be done
just once in "check" rather than in the tests.

For qnio_server, move the detection to "common", simplifying
set_prog_path to stop handling the unused second argument, and
embedding the "realpath" pass.

The variables FULL_MKFS_OPTIONS and FULL_MOUNT_OPTIONS are commented
