Questions about the Python bindings

[dwelch91]

(sending this again, doesn't seem to be making it onto the list...)
Hello,

   I am one of the authors of HPLIP (the set of Linux drivers and tools to
use
   with HP printers on Linux) and am interested in the possibility of using
   DBus as a replacement for our current home-grown IPC mechanism. All of
our
   GUIS and various "middleware" layers are written in Python, so the
   dbus-python bindings are my main interest. I have some questions/concerns
   that I'd appreciate some more information about:
   1. I have noticed that there appear to be two incompatible sets of
bindings,
   the pre-0.80 set and the post-0.80 set. I see that on Ubuntu Edgy that
   0.71is available and installed by default, and that
   0.80 is only on Feisty. Since my software must run on distros of all
"ages",
   what is the preferred strategy to support a single codebase that runs on
all
   versions? Is it possible?
   2. The GUIs in HPLIP are all written in PyQt (version 3 now, version 4 in
   the future). I will need a way to integrate the PyQt/Qt message loop with
   the DBus loop. Is putting the DBus loop in a separate thread the most
   appropriate way to accomplish this (and use Queue or other means of
   inter-thread communication)? Is there a way to integrate the PyQt and
DBus
   message loops together? I see that there are plans for a native Python
loop
   in the future. Any idea when this might happen?
   3. I noticed that there appears to be a dependency on a part of GTK,
glib,
   for the DBus loop. Is this an external dependency? (e.g, is a package
such
   as python-glib required?).
   4. In general, is there a feeling that the bindings are stable enough to
use
   with production software? Should I wait until things like the Python
native
   message loop become available? Even still, how would I support distros
like
   Edgy that only have 0.71 available?

   Any information is much appreciated.

   Regards,

   -Don
