* python: rename qemu.aqmp to qemu.qmpJohn Snow2022-04-211-1/+1
| | | | | | | | | | | | | | | | | | | | | Now that we are fully switched over to the new QMP library, move it back over the old namespace. This is being done primarily so that we may upload this package simply as "qemu.qmp" without introducing confusion over whether or not "aqmp" is a new protocol or not. The trade-off is increased confusion inside the QEMU developer tree. Sorry! Note: the 'private' member "_aqmp" in legacy.py also changes to "_qmp"; not out of necessity, but just to remove any traces of the "aqmp" name.

* iotests: Accommodate async QMP Exception classesJohn Snow2021-11-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | (But continue to support the old ones for now, too.) There are very few cases of any user of QEMUMachine or a subclass thereof relying on a QMP Exception type. If you'd like to check for yourself, you want to grep for all of the derivatives of QMPError, excluding 'AQMPError' and its derivatives. That'd be these: - QMPError - QMPConnectError - QMPCapabilitiesError - QMPTimeoutError - QMPProtocolError - QMPResponseError - QMPBadPortError Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Hanna Reitz <hreitz@redhat.com> Reviewed-by: Kevin Wolf <kwolf@redhat.com> Message-id: 20211026175612.4127598-5-jsnow@redhat.com Signed-off-by: John Snow <jsnow@redhat.com>
