I am using the following decorator for making a function threadsafe. It makes the code more readable. It is almost similar to the one proposed by John Fouhy but the difference is that one work on a single function and that there is no need to create a lock object explicitely.
def threadsafe_function(fn):
"""decorator making sure that the decorated function is thread safe"""
lock = threading.Lock()
def new(*args, **kwargs):
lock.acquire()
try:
r = fn(*args, **kwargs)
except Exception as e:
raise e
finally:
lock.release()
return r
return new
class X:
var = 0
@threadsafe_function
def inc_var(self):
X.var += 1
return X.var
