[PATCH RFC 01/32] python/qemu: create qemu.lib module
From: |

Subject: |
[PATCH RFC 01/32] python/qemu: create qemu.lib module |
Date: |
Thu, 14 May 2020 01:53:32 -0400 |
move python/qemu/*.py to python/qemu/lib/*.py.
To create a namespace package, the 'qemu' directory itself shouldn't
have module files in it. Thus, these files will go under a 'lib' package
directory instead.
Bolster the lib/__init__.py file a little bit, Make the top-level
classes and functions available directly inside the `qemu.lib`
namespace, to facilitate a convenient shorthand:
> from qemu.lib import QEMUQtestMachine, QEMUMonitorProtocol
Lastly, update all of the existing import directives.
(Note: these scripts were not necessarily tested to see if they still
work. Some of these scripts are in obvious states of disrepair and it is
beyond the scope of this patch to attempt to fix them.)
