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_cpunt() |
+-----------------------+-------------------------------+
| psutil.BOOT_TIME | psutil.boot_time() |
+-----------------------+-------------------------------+
| psutil.TOTAL_PHYMEM | psutil.virtual_memory().total |
+-----------------------+-------------------------------+

  • Renamed psutil.* functions:

+--------------------------+-------------------------------+
| Old name | Replacement |
+==========================+===============================+

| - psutil.get_users() | psutil.users() |
+--------------------------+-------------------------------+
| - psutil.get_boot_time() | psutil.boot_time() |
+--------------------------+-------------------------------+

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

| p.get_threads() | p.threads() |
+--------------------------+----------------------+
| p.getcwd() | p.cwd() |
+--------------------------+----------------------+

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

+----------------------+---------------------------------+
| Old name | Replacement |
+======================+=================================+
| p.set_nice() | p.nice(value) |
+----------------------+---------------------------------+

+---------------+-----------------+

  • 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 psutil.wait_procs() has
    been renamed to "returncode" for consistency with subprocess.Popen.

=====

2011-03-20

Enhancements

  • 64_: per-process I/O counters.
  • 116_: per-process wait() (wait for process to terminate and return its exit
    code).
  • 134_: per-process get_threads() returning information (id, user and kernel
    times) about threads opened by process.
  • 136_: process executable path on FreeBSD is now determined by asking the
    kernel instead of guessing it from cmdline[0].
  • 137_: per-process real, effective and saved user and group ids.
  • 140_: system boot time.
  • 142_: per-process get and set niceness (priority).
  • 143_: per-process status.

  • 148_: psutil.Popen class which tidies up subprocess.Popen and psutil.Process
    in a unique interface.
  • 152_: [OSX] get_process_open_files() implementation has been rewritten
    in C and no longer relies on lsof resulting in a 3x speedup.
  • 153_: [OSX] get_process_connection() implementation has been rewritten
    in C and no longer relies on lsof resulting in a 3x speedup.

Bug fixes

  • 83_: process cmdline is empty on OSX 64-bit.
  • 130_: a race condition can cause IOError exception be raised on
    Linux if process disappears between open() and subsequent read() calls.
  • 145_: WindowsError was raised instead of psutil.AccessDenied when using
    process resume() or suspend() on Windows.
  • 146_: 'exe' property on Linux can raise TypeError if path contains NULL
    bytes.

  • 111_: per-process executable name.
  • 113_: exception messages now include process name and pid.
  • 114_: process username Windows implementation has been rewritten in pure
    C and no longer uses WMI resulting in a big speedup. Also, pywin32 is no
    longer required as a third-party dependancy. (patch by wj32)
  • 117_: added support for Windows 2000.
  • 123_: psutil.cpu_percent() and psutil.Process.cpu_percent() accept a
    new 'interval' parameter.
  • 129_: per-process number of threads.

Bug fixes

  • 80_: fixed warnings when installing psutil with easy_install.
  • 81_: psutil fails to compile with Visual Studio.
  • 94_: suspend() raises OSError instead of AccessDenied.
  • 86_: psutil didn't compile against FreeBSD 6.x.
  • 102_: orphaned process handles obtained by using OpenProcess in C were
    left behind every time Process class was instantiated.
  • 111_: path and name Process properties report truncated or erroneous
    values on UNIX.
  • 120_: cpu_percent() always returning 100% on OS X.
  • 112_: uid and gid properties don't change if process changes effective
    user/group id at some point.
  • 126_: ppid, uid, gid, name, exe, cmdline and create_time properties are
    no longer cached and correctly raise NoSuchProcess exception if the process
    disappears.

API changes

  • psutil.Process.path property is deprecated and works as an alias for "exe"
    property.
  • psutil.Process.kill(): signal argument was removed - to send a signal to the
    process use send_signal(signal) method instead.
  • psutil.Process.get_memory_info() returns a nametuple instead of a tuple.
  • psutil.cpu_times() returns a nametuple instead of a tuple.
  • New psutil.Process methods: get_open_files(), get_connections(),
    send_signal() and terminate().
  • ppid, uid, gid, name, exe, cmdline and create_time properties are no longer
    cached and raise NoSuchProcess exception if process disappears.
  • psutil.cpu_percent() no longer returns immediately (see issue 123).
  • psutil.Process.get_cpu_percent() and psutil.cpu_percent() no longer returns
    immediately by default (see issue 123).

  • 55_: test_pid_4 was failing on Windows Vista
  • 57_: some unit tests were failing on systems where no swap memory is
    available
  • 58_: is_running() is now called before kill() to make sure we are going
    to kill the correct process.
  • 73_: virtual memory size reported on OS X includes shared library size
  • 77_: NoSuchProcess wasn't raised on Process.create_time if kill() was
    used first.

2009-03-06

Enhancements

  • 4_: FreeBSD support for all functions of psutil
  • 9_: Process.uid and Process.gid now retrieve process UID and GID.
  • 11_: Support for parent/ppid - Process.parent property returns a
    Process object representing the parent process, and Process.ppid returns
    the parent PID.
  • 12_ & 15:
    NoSuchProcess exception now raised when creating an object
    for a nonexistent process, or when retrieving information about a process
    that has gone away.
  • 21_: AccessDenied exception created for raising access denied errors
    from OSError or WindowsError on individual platforms.
  • 26_: psutil.process_iter() function to iterate over processes as
    Process objects with a generator.
  • Process objects can now also be compared with == operator for equality
    (PID, name, command line are compared).

Bug fixes

  • 16_: [Windows] Special case for "System Idle Process" (PID 0) which
    otherwise would return an "invalid parameter" exception.
  • 17_: get_process_list() ignores NoSuchProcess and AccessDenied
    exceptions during building of the list.
  • 22_: [Windows] Process(0).kill() was failing with an unset exception.
