Kind of a big mess but it was difficult to untangle piecemeal.
Basically this drops nearly all the centralized window tracking
in engine.py and moves it to each UI class. If manager.py wants
to open a details window it does it directly, and vmmDetails tracks
the window object list itself. This simplifies things and makes
the code easier to follow.
There's still some weirdness with vmmConnect and connection callbacks,
but future patches will break those apart.
Have a separate class for tracking the connection list, and emitting
conn-added and conn-removed signals. It exists as a singleton instance
that UI classes can talk directly to
This creates a weird situation where we pass the engine to those
classes UI functions, but this is a step towards untangling that.
While here, get rid of the conn-added connect magic and add a
simpler way to access the connection list from the engine
Rather than key it on the library being available. Makes it much
easier to test both modes of behavior.
Fix up a few inspection bugs while I'm in the area, and convert
it to be more singleton like.
Call the callbacks directly rather than using signals. engine.py
has become a bit of a catchall for shared functionality and this
is a step towards disentangling it
Using these for long term TODO type items is not effective, however
it's nice to label things as FIXME during a coding session and have
pylint warn you about them before pushing.
This can help us find object leaks within the code. virConnectClose
is just a deference and will return 1 if other references are still
floating around.
Does anyone care about this anymore? Unity is gone, if the libs are
present on a gnome install it's always been funky (currently doesn't
display an icon on f27), libappindator seems largely dead upstream,
and traditional systray icons give very similar behavior.
Kill it and see if anyone complains
Use enumerate instead of iterating with range and len.
This pylint message is emitted when code that iterates with range and
len is encountered. Such code can be simplified by using the enumerate
built-in. [1]
In addition, remove some unused variables to avoid warnings
`unused-argument` and `redefined-variable-type`.

A new Python checker was added to warn about using a + operator inside
call of logging methods when one of the operands is a literal string.

Moves the libxml2 bits to a separate xmlapi file and class, a bunch
of cleanups to xmlbuilder internals dealing with XML stuff.
The main point is to experiment with different XML library impls,
since libxml2 is unfun to deal with and we are having python3
issues like
https://bugzilla.gnome.org/show_bug.cgi?id=776815
Currently the domain CPU class has a child property like:
siblings = XMLChildProperty(_CPUCellSibling)
If a user wants to add a new sibling, we add a convenience function:
def add_sibling(self):
obj = _CPUCellSibling(self.conn)
self.add_child(obj)
return obj
Rather than require every child property to define a similar matching
helper function, this adds infrastructure in xmlbuilder to do this
generically for every child property. Now callers can do
obj = guest.cpu.siblings.add_new()
The `ipaddress` is available in Python 3.3+ [1] and backport for
Python 2 is available on PyPI [2].
The main differences between ipaddr and ipaddress are:
- ipaddress *Network classes are equivalent to the ipaddr *Network
class counterparts with the strict flag set to True.
- ipaddress *Interface classes are equivalent to the ipaddr *Network
class counterparts with the strict flag set to False.
- The factory functions in ipaddress were renamed to disambiguate them
from classes.
- A few attributes were renamed to disambiguate their purpose as well.
(eg. network -> network_address, numhosts -> num_addresses)
- A number of methods and functions which returned containers in ipaddr
now return iterators. This includes subnets, address_exclude,
summarize_address_range and collapse_address_list.
Another major difference is that in Python 2 the `ipaddress` module
must use unicode. [3]
