  • v4.4.0 Changes

    2016-10-23

    ✨ Enhancements

    • 🏁 874_: [Windows] net_if_addrs() returns also the netmask.
    • 🐧 887_: [Linux] virtual_memory()'s 'available' and 'used' values are more precise and match "free" cmdline utility. "available" also takes into account LCX containers preventing "available" to overflow "total".
    • ⚡️ 891_: procinfo.py script has been updated and provides a lot more info.

    🐛 Bug fixes

    • 🍎 514_: [macOS] possibly fix Process.memory_maps() segfault (critical!).
    • 🍎 783_: [macOS] Process.status() may erroneously return "running" for zombie processes.
    • 🏁 798_: [Windows] Process.open_files() returns and empty list on Windows 10.
    • 🐧 825_: [Linux] cpu_affinity; fix possible double close and use of unopened socket.
    • 🏁 880_: [Windows] Handle race condition inside psutil_net_connections.
    • 885_: ValueError is raised if a negative integer is passed to cpu_percent() functions.
    • 🐧 892_: [Linux] Process.cpu_affinity([-1]) raise SystemError with no error set; now ValueError is raised.
    • 906_: [BSD] disk_partitions(all=False) returned an empty list. Now the argument is ignored and all partitions are always returned.
    • 907_: [FreeBSD] Process.exe() may fail with OSError(ENOENT).
    • 🍎 908_: [macOS, BSD] different process methods could errounesuly mask the real error for high-privileged PIDs and raise NoSuchProcess and AccessDenied instead of OSError and RuntimeError.
    • 🍎 909_: [macOS] Process open_files() and connections() methods may raise OSError with no exception set if process is gone.
    • 🍎 916_: [macOS] fix many compilation warnings.

    • 858_: Process.as_dict() should not return memory_info_ex() because it's deprecated.
    • 🏁 863_: [Windows] memory_map truncates addresses above 32 bits
    • 🏁 866_: [Windows] win_service_iter() and services in general are not able to handle unicode service names / descriptions.
