Request for feature in GRC

GNU Radio
1

I recently had a problem with GRC where two threads were accessing
a set_variable callback creating some unwanted behaviour
(actually crashing the xmlrpc server).
I fixed it by editing the python file created by GRC and locking the
set_
callback.

I thought that this can be a separate and interesting feature of the
“variable” block in GRC, ie, a selector that selects if the user wants
it
to be “protected”.
Then a piece of code like below will be generated:

self.lock = threading.Lock()

def set_variable(self, value):
    self.lock.acquire()
    self.value = value
    other set_ cllabacks
    self.lock.release()

best,
Achilleas

Achilleas,

you can put feature requests on our issue tracker, where they are less
likely to get lost than in our list archives. There’s also the roadmap:
http://gnuradio.org/redmine/projects/gnuradio/wiki/GRCroadmap.

Of course, the GRC team is pretty understaffed, and could probably take
on a couple more volunteers cough cough.

Cheers,
M
