Unable to Launch allzpark On New OSX Python 3.9 Install

[mstreatfield]

Hello,

After following the quickstart for bleeding-rez and quickstart for allzpark, I get the following error on OSX when trying to launch allzpark for the first time.

Python has been installed using brew to replace the system python:

Python 3.9.0 (default, Oct 27 2020, 14:15:17)
[Clang 12.0.0 (clang-1200.0.32.21)]

And I'm using the latest version of bleeding-rez:

bleeding-rez 2.40.5

It looks like time.clock was deprecated around Python 3.3 and then removed in 3.8 due to platform-dependent behaviour. Updating to using time.time instead is enough to move past the error and have allzpark start as expected. The PEP-418 suggests using time.perf_counter might be preferable.

Sounds like it might be simple to resolve - unfortunately, I'm not able to make a pull request for a fix at the moment.

Mark.

Oops, that has been fixed in #121 (commit 99c7de7), but not yet released. Could you directly pull current master branch and have a test ?

[davidlatwe]

Okay, I just made a release 1.3.67, wait a few minutes and you could pip install -U allzpark !

The PEP-418 suggests using time.perf_counter might be preferable.

Hmmm, the replacment I used was process_time, looks like using perf_counter is better indeed.

[mstreatfield]

I pip installed the latest version and it's working perfectly now. Thank you for the quick turnaround, I appreciate it!

My read of the documentation is that perf_counter will be more accurate for time deltas, although perhaps this isn't needed if what is being measured is application/module load time.

[davidlatwe]

Thanks for confirm !

Regarding perf_counter, yeah I agree. Didn't think much at the time being, was trying to get pass CI testing and thought it doesn't matter much for our use case.

Anyway, PR is welcome ! (not limited to this issue of course :P)
