python: GIL deadlock if Endpoint::libHandleEvents and Call::getInfo are called concurrently under some conditions

Open azertyfun opened this issue 3 years ago • 0 comments

Describe the bug

Hi,

My code sometimes deadlocks when ep.libHandleEvents() is called while another thread is already handling Call::getInfo(). This seems to only happen when a call is initiated outside of the main thread.

If you attempt to reproduce, you might have to retry quite a few times; as the race condition happens in the print call, it's not terribly likely to happen.

Note that the backtrace is always the same once you can reproduce the issue, it always deadlocks on libHandleEvents() on the main thread and while building the f-string with getInfo on the worker thread.

I've worked around the issue by having a global lock held by libHandleEvents as well as all my Call callbacks.

Steps to reproduce

Make the sample python app;
Replace the time.sleep(10) with a loop over ep.libHandleEvents(100) as the original method leads to a segfault (this seems to be the standard way to do things from what I've seen online);
Start a new thread, call libRegisterThread;
In that new thread, when registered, initiate a call;
In the Call handlers, print some debug info using self.getInfo().

Python code:

#!/usr/bin/env python3

import threading
import time

import pjsua2 as pj

CALL_ADDRESS = 'sip:<rempte_user>@<server>'
ACC_URI = 'sip:<user>@<server>'
REG_URI = 'sip:<server>'
USER = '<user>'
PASS = '<pass>'

REGISTERED = threading.Event()

# Subclass to extend the Account and get notifications etc.
class Account(pj.Account):
  def onRegState(self, prm):
      print(f'***OnRegState: {prm.reason}')
      if prm.reason == 'OK':
          REGISTERED.set()

class Call(pj.Call):
    def __init__(self, account: Account, dest: str = None):
        self.account = account
        self.dest = dest

        super().__init__(account)

    def makeCall(self):
        prm = pj.CallOpParam(True)

        print(f'Call<{self.getId()}> calling {self.dest}')
        super().makeCall(self.dest, prm)

    def onCallState(self, prm):
        i = self.getInfo()

        print(f'Call<{self.getId()}> new state: {self.getInfo().stateText}')
            del self

    def onCallMediaState(self, prm):
        print(f'Call<{self.getId()}> media event: {self.getInfo().stateText}')

class MyThread(threading.Thread):
    def __init__(self, ep, acc):
        super().__init__(daemon=True)
        self.ep = ep
        self.acc = acc

    def run(self):
        self.ep.libRegisterThread(self.name)

        call_made = False
        while True:
            if REGISTERED.is_set() and not call_made:
                c = Call(self.acc, CALL_ADDRESS)
                c.makeCall()
                call_made = True
            time.sleep(1)

# pjsua2 test function
def main():
    # Create and initialize the library
    ep_cfg = pj.EpConfig()
    ep_cfg.uaConfig.threadCnt = 0 # Python does not like PJSUA2's thread. It will result in segment fault
    ep_cfg.uaConfig.mainThreadOnly = True
    ep_cfg.logConfig.level = 2
    ep = pj.Endpoint()
    ep.libCreate()
    ep.libInit(ep_cfg)
    ep.audDevManager().setNullDev()

    # Create SIP transport. Error handling sample is shown
    sipTpConfig = pj.TransportConfig()
    sipTpConfig.port = 5060
    ep.transportCreate(pj.PJSIP_TRANSPORT_UDP, sipTpConfig)
    # Start the library
    ep.libStart()

    acfg = pj.AccountConfig()
    acfg.idUri = ACC_URI
    acfg.regConfig.registrarUri = REG_URI
    cred = pj.AuthCredInfo("digest", "*", USER, 0, PASS)
    acfg.sipConfig.authCreds.append( cred )
    # Create the account
    acc = Account()
    acc.create(acfg)

    MyThread(ep, acc).start()

    # handle events
    for _ in range(100): # run for about 10 seconds
        ep.libHandleEvents(100)

    # Destroy the library
    ep.libDestroy()
