Thanks a lot for that link Jeremy, it was really helpful. After reading up on it, my take is that winapi is the most appropriate place for this, it is a non public api that's used in the stdlib. I've used Windows APIs in a way that we don't need to manually start up a thread and call a calc_load function, instead using a callback invoked by windows. Internally this uses a thread pool, but it means we don't have to worry about managing the thread ourselves. The load is stored as a global but the winapi module is already marked as "-1" indicating it has global state, so that shouldn't be a problem. https://docs.python.org/3/c-api/module.html#c.PyModuleDef.m_size Like Jeremy noted, using WMI does add a 5mb overhead or so to the calling process. One more caveat is that the PdhAddEnglishCounterW function is only available in Vista+. I'm not sure if we still support Windows XP, but the alternative is to use PdhAddCounter, which breaks if the system language is not english because the counter paths are localized. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34060> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
