    API changes

    For the sake of consistency a lot of psutil APIs have been renamed. In most cases accessing the old names will work but it will cause a 🗄 DeprecationWarning.

    • psutil.* module level constants have being replaced by functions:

    +-----------------------+----------------------------------+ | Old name | Replacement | +=======================+==================================+ | psutil.NUM_CPUS | psutil.cpu_count() | +-----------------------+----------------------------------+ | psutil.BOOT_TIME | psutil.boot_time() | +-----------------------+----------------------------------+ | psutil.TOTAL_PHYMEM | virtual_memory.total | +-----------------------+----------------------------------+

    • 📇 Renamed psutil.* functions:

    +------------------------+-------------------------------+ | Old name | Replacement | +========================+===============================+ | psutil.get_pid_list() | psutil.pids() | +------------------------+-------------------------------+ | psutil.get_users() | psutil.users() | +------------------------+-------------------------------+ | psutil.get_boot_time() | psutil.boot_time() | +------------------------+-------------------------------+

    • All Process_ get_* methods lost the get_ prefix. E.g. get_ext_memory_info() was renamed to memory_info_ex(). Assuming p = psutil.Process():

    +--------------------------+----------------------+ | Old name | Replacement | +==========================+======================+ | p.get_children() | p.children() | +--------------------------+----------------------+ | p.get_connections() | p.connections() | +--------------------------+----------------------+ | p.get_cpu_affinity() | p.cpu_affinity() | +--------------------------+----------------------+ | p.get_cpu_percent() | p.cpu_percent() | +--------------------------+----------------------+ | p.get_cpu_times() | p.cpu_times() | +--------------------------+----------------------+ | p.get_ext_memory_info() | p.memory_info_ex() | +--------------------------+----------------------+ | p.get_io_counters() | p.io_counters() | +--------------------------+----------------------+ | p.get_ionice() | p.ionice() | +--------------------------+----------------------+ | p.get_memory_info() | p.memory_info() | +--------------------------+----------------------+ | p.get_memory_maps() | p.memory_maps() | +--------------------------+----------------------+ | p.get_memory_percent() | p.memory_percent() | +--------------------------+----------------------+ | p.get_nice() | p.nice() | +--------------------------+----------------------+ | p.get_num_ctx_switches() | p.num_ctx_switches() | +--------------------------+----------------------+ | p.get_num_fds() | p.num_fds() | +--------------------------+----------------------+ | p.get_num_threads() | p.num_threads() | +--------------------------+----------------------+ | p.get_open_files() | p.open_files() | +--------------------------+----------------------+ | p.get_rlimit() | p.rlimit() | +--------------------------+----------------------+ | p.get_threads() | p.threads() | +--------------------------+----------------------+ | p.getcwd() | p.cwd() | +--------------------------+----------------------+

    • All Process_ set_* methods lost the set_ prefix. Assuming p = psutil.Process():

    +----------------------+---------------------------------+ | Old name | Replacement | +======================+=================================+ | p.set_nice() | p.nice(value) | +----------------------+---------------------------------+ | p.set_ionice() | p.ionice(ioclass, value=None) | +----------------------+---------------------------------+ | p.set_cpu_affinity() | p.cpu_affinity(cpus) | +----------------------+---------------------------------+ | p.set_rlimit() | p.rlimit(resource, limits=None) | +----------------------+---------------------------------+

    • Except for pid, all Process_ class properties have been turned into methods. This is the only case which there are no aliases. Assuming p = psutil.Process():

    +---------------+-----------------+ | Old name | Replacement | +===============+=================+ | p.name | p.name() | +---------------+-----------------+ | p.parent | p.parent() | +---------------+-----------------+ | p.ppid | p.ppid() | +---------------+-----------------+ | p.exe | p.exe() | +---------------+-----------------+ | p.cmdline | p.cmdline() | +---------------+-----------------+ | p.status | p.status() | +---------------+-----------------+ | p.uids | p.uids() | +---------------+-----------------+ | p.gids | p.gids() | +---------------+-----------------+ | p.username | p.username() | +---------------+-----------------+ | p.create_time | p.create_time() | +---------------+-----------------+

    • timeout parameter of cpu_percent* functions defaults to 0.0 instead of 0.1.
    • 🗄 long deprecated psutil.error module is gone; exception classes now live in "psutil" namespace only.
    • Process_ instances' retcode attribute returned by wait_procs()_ has been renamed to returncode for consistency with subprocess.Popen.
