2018-06-11iotests.py: Add qemu_io_silentMax Reitz
With qemu-io now returning a useful exit code, some tests may find it sufficient to just query that instead of logging (and filtering) the whole output.

2018-05-30qemu-iotests: Rewrite 210 for blockdev-create jobKevin Wolf
This rewrites the test case 210 to work with the new x-blockdev-create job rather than the old synchronous version of the command. All of the test cases stay the same as before, but in order to be able to implement proper job handling, the test case is rewritten in Python.

2017-07-24qemu-iotests: Avoid unnecessary sleepsKevin Wolf
Test cases 030, 041 and 055 used to sleep for a second after calling block-job-pause to make sure that the block job had time to actually get into paused state. We can instead poll its status and use that one second only as a timeout. The tests also slept a second for checking that the block jobs don't make progress while being paused. Half a second is more than enough for this. These changes reduce the total time for the three tests by 25 seconds on my laptop (from 155 seconds to 130).

2016-05-12qemu-iotests: iotests: fail hard if not run via "check"Sascha Silbe
Running an iotests-based Python test directly might appear to work, but may fail in subtle ways and is insecure: - It creates files with predictable file names in a world-writable location (/var/tmp). - Tests expect the environment to be set up by check. E.g. 041 and 055 may take the wrong code paths if QEMU_DEFAULT_MACHINE is not set. This can lead to false negatives. Instead fail hard and tell the user we want to be run via "check". The actual environment expected by the tests is currently only defined by the implementation of "check". We use two of the environment variables set by "check" as indication of whether we're being run via "check". Anyone writing their own test runner (replacing "check") will need to replicate the full environment (in a broader sense, not just environment variables) provided by "check" anyway, including setting the two environment variables we check. Whereas a regular developer just trying to invoke the tests usually won't have both of these defined in their environment so we can catch their mistake and give out useful advice.

That typo prevented "from iotests import *" (which is the only case where iotests.__all__ is used at all) from ever working.

qemu-iotests test case 148 already had some code for skipping the test if quorum support is missing, but it didn't work in all cases. TestQuorumEvents.setUp() gets run before the actual test class (which contains the skipping code) and tries to start qemu with a drive using the quorum driver. For some reason this works fine when using qcow2, but fails for raw. As the entire test case requires quorum, just check for availability before even starting the test suite.

2016-03-30tests: redirect stderr to stdout for iotestsDaniel P. Berrange
The python I/O tests helper for running qemu-img/qemu-io setup stdout to be captured to a pipe, but left stderr untouched. As a result, if something failed in qemu-img/ qemu-io, data written to stderr would get output directly and not line up with data on the test stdout due to buffering. If we explicitly redirect stderr to the same pipe as stdout, things are much clearer when they go wrong. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2015-12-18qemu-iotests: Remove cache mode test without mediumKevin Wolf
Specifying the cache mode for a driver without a medium is not a useful thing to do: As long as there is no medium, the cache mode doesn't make a difference, and once the 'change' command is used to insert a medium, it ignores the old cache mode and makes the new medium use cache=writethrough. Later patches will make it an error to specify the cache mode for an empty drive. Remove the corresponding test case.

2015-12-18blockdev: Set 'format' indicates non-empty driveKevin Wolf
Creating an empty drive while specifying 'format' doesn't make sense. The specified format driver would simply be ignored. Make a set 'format' option an indication that a non-empty drive should be created. This makes 'format' consistent with 'driver' and allows using it with a block driver that doesn't need any other options (like null-co/null-aio).

2015-09-04iotests: Warn if python subprocess is killedMax Reitz
Currently, if a subprocess of a python test (i.e. qemu-io, qemu-img, or qemu) receives a signal and is subsequently aborted, this is not logged. This patch makes python tests always check the exit code of these subprocesses, and emit a message if they have been killed.
