About
=====

psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports Linux, Windows, macOS, Sun Solaris, FreeBSD, OpenBSD, NetBSD and AIX. Supported Python versions are cPython 3.6+ and PyPy.

**Enhancements**

- #2705: [Linux]: `Process.wait()`_ now uses ``pidfd_open()`` + ``poll()`` for
  waiting, resulting in no busy loop and faster response times. Requires
  Linux >= 5.3 and Python >= 3.9. Falls back to traditional polling if
  unavailable.
- #2705: [macOS], [BSD]: `Process.wait()`_ now uses ``kqueue()`` for waiting,
  resulting in no busy loop and faster response times.

**Bug fixes**

- #2701, [macOS]: fix compilation error on macOS < 10.7.  (patch by Sergey
  Fedorov)
- #2707, [macOS]: fix potential memory leaks in error paths of
  `Process.memory_full_info()` and `Process.threads()`.
- #2708, [macOS]: Process.cmdline()`_ and `Process.environ()`_ may fail with
  ``OSError: [Errno 0] Undefined error`` (from ``sysctl(KERN_PROCARGS2)``).
  They now raise `AccessDenied`_ instead.
