John Snow	37094b6dd5	python: rename qemu.aqmp to qemu.qmp 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.

John Snow	0590860242	scripts/render-block-graph: switch to AQMP Creating an instance of qemu.aqmp.ExecuteError is too involved here, so just drop the specificity down to a generic QMPError.

Vladimir Sementsov-Ogievskiy	64631f3681	block: drop BLK_PERM_GRAPH_MOD First, this permission never protected a node from being changed, as generic child-replacing functions don't check it. Second, it's a strange thing: it presents a permission of parent node to change its child. But generally, children are replaced by different mechanisms, like jobs or qmp commands, not by nodes. Graph-mod permission is hard to understand. All other permissions describe operations which done by parent node on its child: read, write, resize. Graph modification operations are something completely different. The only place where BLK_PERM_GRAPH_MOD is used as "perm" (not shared perm) is mirror_start_job, for s->target. Still modern code should use bdrv_freeze_backing_chain() to protect from graph modification, if we don't do it somewhere it may be considered as a bug. So, it's a bit risky to drop GRAPH_MOD, and analyzing of possible loss of protection is hard. But one day we should do it, let's do it now. One more bit of information is that locking the corresponding byte in file-posix doesn't make sense at all.

John Snow	e3a23b4803	python/qmp.py: re-absorb MonitorResponseError When I initially split this out, I considered this more of a machine error than a QMP protocol error, but I think that's misguided. Move this back to qmp.py and name it QMPResponseError. Convert qmp.command() to use this exception type.

John Snow	abf0bf998d	python/qemu: split QEMUMachine out from underneath __init__.py It's not obvious that something named __init__.py actually houses important code that isn't relevant to python packaging glue. Move the QEMUMachine and related error classes out into their own module. Adjust users to the new import location.

Cleber Rosa	8f8fd9edba	Introduce a Python module structure This is a simple move of Python code that wraps common QEMU functionality, and are used by a number of different tests and scripts. By treating that code as a real Python module, we can more easily: * reuse code * have a proper place for the module's own unittests * apply a more consistent style * generate documentation Signed-off-by: Cleber Rosa <crosa@redhat.com> Reviewed-by: Caio Carrara <ccarrara@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Message-Id: <20190206162901.19082-2-crosa@redhat.com> Signed-off-by: Cleber Rosa <crosa@redhat.com>	7 years ago
Vladimir Sementsov-Ogievskiy	dc2b651a0b	scripts: add render_block_graph function for QEMUMachine Render block nodes graph with help of graphviz. This new function is for debugging, so there is no sense to put it into qemu.py as a method of QEMUMachine. Let's instead put it separately.
