[OE-core] ValueError: insecure string pickle with latest bitbake

[Martin Jansa]

Hi,

last couple of days many of my jenkins builds failed with exception like
this:

ERROR: An uncaught exception occured in runqueue, please see the failure below:
ERROR: Running idle function
Traceback (most recent call last):
  File "/home/jenkins/oe/shr-core-branches/shr-core/bitbake/lib/bb/cooker.py", line 1182, in buildTargetsIdle(server=<ProcessServer(ProcessServer-2, started)>, rq=<bb.runqueue.RunQueue instance at 0x16a95d40>, abort=False):
                 try:
    >                retval = rq.execute_runqueue()
                 except runqueue.TaskFailure as exc:
  File "/home/jenkins/oe/shr-core-branches/shr-core/bitbake/lib/bb/runqueue.py", line 1093, in RunQueue.execute_runqueue():
                 try:
    >                self.teardown_workers()
                 except:
  File "/home/jenkins/oe/shr-core-branches/shr-core/bitbake/lib/bb/runqueue.py", line 925, in RunQueue.teardown_workers():
             self.workerpipe = None
    >        self._teardown_worker(self.fakeworker, self.fakeworkerpipe)
             self.fakeworker = None
  File "/home/jenkins/oe/shr-core-branches/shr-core/bitbake/lib/bb/runqueue.py", line 906, in RunQueue._teardown_worker(worker=<subprocess.Popen object at 0xcb4e690>, workerpipe=<bb.runqueue.runQueuePipe instance at 0x11c17710>):
             while worker.returncode is None:
    >            workerpipe.read()
                 worker.poll()
  File "/home/jenkins/oe/shr-core-branches/shr-core/bitbake/lib/bb/runqueue.py", line 2095, in runQueuePipe.read():
                 while index != -1 and self.queue.startswith("<event>"):
    >                event = pickle.loads(self.queue[7:index])
                     bb.event.fire_from_worker(event, self.d)
ValueError: insecure string pickle

and it repeats the same exception very quickly (generated 3GB log in ~ hour)

It doesn't happen always, it seems to be triggered in different places in build.

Anyone else seeing this as well?

I'll add some debug output around it and wait for it to happen again.
