* python/qmp: switch qmp-shell to AQMPJohn Snow2022-01-211-0/+3
| | | | | | | | We have a replacement for async QMP, but it doesn't have feature parity yet. For now, then, port the old tool onto the new backend. Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
* python/aqmp: rename AQMPError to QMPErrorJohn Snow2022-01-211-2/+2
| | | | | | | | | This is in preparation for renaming qemu.aqmp to qemu.qmp. I should have done this from this from the very beginning, but it's a convenient time to make sure this churn is taken care of.

* python/aqmp: copy type definitions from qmpJohn Snow2022-01-211-2/+20
| | | | | | | | | | Copy the remaining type definitions from QMP into the qemu.aqmp.legacy module. Now, users that require the legacy interface don't need to import anything else but qemu.aqmp.legacy wrapper.

* python/aqmp: add __del__ method to legacy interfaceJohn Snow2022-01-211-0/+18
| | | | | | | | | | | | | | | | | | | | | | | asyncio can complain *very* loudly if you forget to back out of things gracefully before the garbage collector starts destroying objects that contain live references to asyncio Tasks. The usual fix is just to remember to call aqmp.disconnect(), but for the sake of the legacy wrapper and quick, one-off scripts where a graceful shutdown is not necessarily of paramount imporance, add a courtesy cleanup that will trigger prior to seeing screenfuls of confusing asyncio tracebacks. Note that we can't *always* save you from yourself; depending on when the GC runs, you might just seriously be out of luck. The best we can do in this case is to gently remind you to clean up after yourself. (Still much better than multiple pages of incomprehensible python warnings for the crime of forgetting to put your toys away.)

* python/aqmp: Create sync QMP wrapper for iotestsJohn Snow2021-11-011-0/+138
This is a wrapper around the async QMPClient that mimics the old, synchronous QEMUMonitorProtocol class. It is designed to be interchangeable with the old implementation. It does not, however, attempt to mimic Exception compatibility.
