passlib 1.7.1 fails to run under windows + python 3.8 (b1) because it references time.clock, which apparently has been removed from the standard library. The errors occur in utils.__init__ around line 844 (sorry, patched my local version) and line 907. Here is what I did:
# pick best timer function to expose as "tick" - lifted from timeit module.
if sys.version_info > (3, 3):
from time import process_time as timer
# FIXME or time.monotonic or time.perf_counter or time.process_time or any of these with _ns
elif sys.platform == "win32":
# On Windows, the best timer is time.clock()
from time import clock as timer
# On most other platforms the best timer is time.time()
from time import time as timer
if sys.version_info > (3,3):
clk = time.process_time()
clk = time.clock()
with time.clock() replaced by clk in line 914
In both cases I’m not sure which timer function is best for passlib. (see the FIXME).
