2016-02-08scripts/qmp: Use Python 2.6 "except E as ..." syntaxMarkus Armbruster1-2/+2
PEP 8 calls for it, because it's forward compatible with Python 3. Supported since Python 2.6, which we require (commit fec2103).

2015-04-28iotests: add QMP event waiting queueJohn Snow1-30/+65
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.

2014-02-28qmp: Check for returned data from __json_read in get_eventsFam Zheng1-1/+6
When QEMU process aborts and socket is closed, qmp client will not detect it. When this happens, some qemu-iotests scripts will enter an endless loop waiting for qmp events. It's better we raise an exception in qmp.py to catch this and make the test script stop.
