Hi,
I would like to report a bug in pjsip-apps/src/python/samples/registration.py:
There is a race-condition when waiting for the registration to finish.
The reason is, that the semaphore is created in wait, which may be too
late.
Demo:
add "time.sleep(2)" between acc.set_callback(acc_cb) and acc_cb.wait():
...
try:
...
acc_cb = MyAccountCallback(acc)
acc.set_callback(acc_cb)
time.sleep(2)
acc_cb.wait()
...
Solution: Create the semaphore before, e.g. in MyAccountCallback.__init__.
I've attached a patch.
thanks,
Roland
