Message 304948 - Python tracker (original) (raw)

Marc-Andre: "Yes, to avoid yet another Python 2/3 difference. It should be replaced with the appropriate variant on Windows and non-Windows platforms. From Serhiy's response that's time.process_time() on non-Windows platforms and time.perf_counter() on Windows."

I don't understand why you mean by "replaced with". Do you mean modify the implementation of the time.clock()?

I would like to kill time.clock() beceause it behaves differently on Windows and non-Windows platforms. There are two choices:

• deprecate time.clock() and later remove time.clock() -- it's deprecated since Python 3.3, and Python 3.7 now emits a DeprecationWarning
• modify time.clock() to get the same behaviour on all platforms: I proposed to modify time.clock() to become a simple alias to time.perf_counter()

Now I'm confused. I'm not sure that I understood what you suggest.

Note: time.clock() already behaves like time.perf_counter() on Windows and time.process_time() on non-Windows. It's exactly how it's implemented. But I consider that it's a bug, and I want to fix it.

"The documentation can point to the new functions and recommend these over time.clock()."

It's already done in the doc since Python 3.3, no?

https://docs.python.org/dev/library/time.html#time.clock

"Deprecated since version 3.3: The behaviour of this function depends on the platform: use perf_counter() or process_time() instead, depending on your requirements, to have a well defined behaviour."
