Attached is a patch based on the original patch, meant to have better
performance.
On my PC, this:
import sys, time, uuid
def uu(n):
t = time.time()
for x in range(n):
uuid.uuid1()
print('%.3f microseconds' % ((time.time() - t) * 1000000.0 / n))
uu(50000)
records a time of 38.5 microseconds unpatched (still using ctypes/libuuid) and
a time of 16.5 microseconds afterwards.
uuid4() results in an improvement from 30 microseconds to 9 microseconds. From
what I could see, what took the most time was the call to UUID() with a bytes
object. That's why this patch passes in the uuid as a long.
It also fixes setup.py to check for the uuid.h header.
