[issue21617] importlib reload can fail with AttributeError if module removed from sys.path

Brett Cannon added the comment: If there's no spec, Michael, then your work-around is the next best option (and reloading never actually replaces the actual module object or it's dict/global namespace because we don't know who is holding on to a reference). -- nosy: +ncoghlan

[issue21617] importlib reload can fail with AttributeError if module removed from sys.path

Michael Forbes added the comment: It seems that a reasonable workaround (if you generate your own `spec`) is to call `spec.loader.exec_module(mod)`. This seems to reload the module into the same namespace. (I was afraid that it might replace the namespace hence the desire to use

Ammar Askar added the comment: Roger, personally I don't think its worth it to complicate the code in order to use the thread pool API. Especially considering this is just a private API and the only consumer will be the test suite runner. Let's see what the core devs think when this gets

Ronald Oussoren added the comment: As I mentioned in msg314304 this is almost certainly expected behavior on macOS because Apple’s GUI frameworks are not fork()-safe. There is nothing we can do about this other than changing the default spawn mechanism for multiprocessing on macOS. -- On

[issue34060] regrtest: log "CPU usage" on Windows

Jeremy Kloth added the comment: Correct. Windows provides the building blocks for implementing getloadavg(), but does not provide an interface that does the averaging. That is deferred to a per application basis. The best that an application can do for that is to use thread pools. You

Ammar Askar added the comment: Aah, yeah I don't think there's a good way of doing it purely from the windows API. There might be a way to enumerate through all the processes and see if they're queued up but I didn't look into it. In this case it should be fine, we just pay a bit of WMI

Giampaolo Rodola' added the comment: > Giampaolo, on your psutil issue you specifically said, "(possibly without > using WMI)" Is there any particular problem with using WMI? Performance. In general WMI is (a lot) slower than the Windows API counterpart (psutil never uses WMI except in unit

Tim Peters added the comment: Well, all 6 operations "are calculated as though carried out in two's complement with an infinite number of sign bits", so I'd float that part out of the footnote and into the main text. When, e.g., you're thinking of ints _as_ bitstrings, it's essentially
