      iotests.py: add FilePath context manager · f4844ac0
      由 Stefan Hajnoczi 提交于 
      The scratch/ (TEST_DIR) directory is not automatically cleaned up after
test execution.  It is the responsibility of tests to remove any files
they create.

A nice way of doing this is to declare files at the beginning of the
test and automatically remove them with a context manager:

  with iotests.FilePath('test.img') as img_path:
      qemu_img(...)
      qemu_io(...)
  # img_path is guaranteed to be deleted here

      qemu-iotests: Avoid unnecessary sleeps · 2c93c5cb
      由 Kevin Wolf 提交于 
      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).

      iotest: fix python based IO tests · 4c44b4a4
      由 Daniel P. Berrange 提交于 
      The previous commit refactoring iotests.py:

  commit 66613974
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Wed Jul 20 14:23:10 2016 +0100

    scripts: refactor the VM class in iotests for reuse

was not properly tested and included a number of broken
bits.

 - The 'event_match' method was not moved into qemu.py
 - The 'self._args' list parameter in QEMUMachine needs
   to be copied otherwise modifications will affect the
   global 'qemu_opts' variable in iotests.py
 - The QEMUQtestMachine class methods had inverted
   parameter order for the super() calls
 - The QEMUQtestMachine class forgot to add
   '-machine accel=qtest'
 - The QEMUQtestMachine class constructor needs to set
   a default 'name' value before using it as it may
   be None
 - The QEMUQtestMachine class constructor needs to use
   named parameters when calling the super constructor
   as it is leaving out some positional parameters.
 - The 'qemu_prog' variable should be a string not a
   list in iotests.py
 - The VM classs constructor needs to use named
   parameters when calling the super constructor
   as it is leaving out some positional parameters.
 - The path to the socket-scm-helper needs to be
   passed into the QEMUMachine class

      qemu-iotests: iotests: fail hard if not run via "check" · 5a8fabf3
      由 Sascha Silbe 提交于 
      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.

      qemu-iotests: iotests.py: get rid of __all__ · 3ef3dcef
      由 Sascha Silbe 提交于 
      The __all__ list contained a typo for as long as the iotests module
existed. That typo prevented "from iotests import *" (which is the
only case where iotests.__all__ is used at all) from ever working.

The names used by iotests are highly prone to name collisions, so
importing them all unconditionally is a bad idea anyway. Since __all__
is not adding any value, let's just get rid of it.

      qemu-iotests: 148: properly skip test if quorum support is missing · 3f647b51
      由 Sascha Silbe 提交于 
      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. Introduce a verify_quorum()
function in iotests.py for this purpose so future test cases can make
use of it.

      qemu-iotests: Remove cache mode test without medium · fc17c259
      由 Kevin Wolf 提交于 
      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.

      blockdev: Set 'format' indicates non-empty drive · 39c4ae94
      由 Kevin Wolf 提交于 
      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).

      qemu-iotests: Make debugging python tests easier · aa4f592a
      由 Fam Zheng 提交于 
      Adding "-d" option. The output goes to "tee" so it appears in your
console. Also, raise the verbosity of unnitest runner.

When testing a topic branch, it's possible that a bug introduced by a
code change makes the python test case hang, with debug output, it is
much easier to locate the problem.

This can also be helpful if you want to watch the progress of a python
test, it offers you a way to sense the speed of each test case method
you're writing.

Note: because there is no easy way to get *both* the verbose output and
the output expected by ./check comparison, the case would always fail
with an "output mismatch". The sole purpose of using this option is
giving developers a quick way to debug when things go wrong.

      iotests: add QMP event waiting queue · 7898f74e
      由 John Snow 提交于 
      A filter is added to allow callers to request very specific
events to be pulled from the event queue, while leaving undesired
events still in the stream.

This allows us to poll for completion data for multiple asynchronous
events in any arbitrary order.

A new timeout context is added to the qmp pull_event method's
wait parameter to allow tests to fail if they do not complete
within some expected period of time.

Also fixed is a bug in qmp.pull_event where we try to retrieve an event
from an empty list if we attempt to retrieve an event with wait=False
but no events have occurred.
