Crash on OS X when accessing keyring from multiple processes #281
Description
OS: Mac OS Sierra, 10.12.5
Version: 10.3
Description: Crash happens (with -11 exit code) when trying to ask for a password both from the main process and from a subprocess. See the repro case below.
After some digging, it seems that the issue happens in the SecKeychainFindGenericPassword() call of backends/_OS_X_API.py: find_generic_password().
import keyring
from multiprocessing import Process
from_address = '[email protected]'
def my_subprocess():
keyring.get_password('myapp', from_address)
print('ok')
# comment out the line below to get things work(around)
keyring.get_password('myapp', from_address)
proc1 = Process(target=my_subprocess)
proc1.start()
proc1.join()
print(proc1.exitcode)
proc2 = Process(target=my_subprocess)
proc2.start()
proc2.join()
print(proc2.exitcode)
# expected output:
# ok
# 0
# ok
# 0
#
# current output:
# -11
# -11
