[Bluez-devel] Python/Gtk2 test application for the new D-BUS interface

[Bluez-devel] Python/Gtk2 test application for the new D-BUS interface

[Johan Hedberg]

Hi,

In case someone is interested, I started developing a pygtk based test
application for the new D-BUS interface which we are working on. You can
get the first version here:
http://www.iki.fi/~jhedberg/bluez-python.tar.gz

Note that the code is in a very early stage. Currently it supports the
inquiry, periodic inquiry and remote name method calls and signals.

To execute the application, run bluez-python/btdbus.py

Johan

it crashes with the name resolve on AMD64, but it is a great starting
point.

There are some small changes to how name resolving is done in the latest
version (0.2) available here:
http://www.iki.fi/~jhedberg/bluez-python/

If you still get the crash, could you perhaps send a backtrace of it? (I
don't have a 64bit machine to reproduce it on).

it is still crashing. It also happens with the start of periodic inquiry
and both are producing a segmentation fault. If I start the program and
then call 'hcitool scan' the name resolving seems to work flawless.

So how do I create a backtrace with Python for you?

I was thinking of the several lines of "traceback" information that
python usually prints when the code does something bad. If the program
is segfaulting without producing any other output I don't really have
any expecrience in debugging that kind of problems. In the case that we
have found a bug in the python D-BUS bindings debugging could be even
harder.

I tested it on two machines running Ubuntu and both are crashing. One
was amd64 and one i386 based. So basically I think that the D-Bus is at
fault here. And there is no debugging output from Python. The only thing
I saw is an segmentation fault.
