Bug tracker at http://code.google.com/p/psutil/issues
0.2.0 - 2010-11-13
------------------
NEW FEATURES
* Issue 79: per-process open files.
* Issue 88: total system physical cached memory.
* Issue 88: total system physical memory buffers used by the kernel.
* Issue 91: per-process send_signal() and terminate() methods.
* Issue 95: NoSuchProcess and AccessDenied exception classes now provide "pid",
"name" and "msg" attributes.
* Issue 97: per-process children.
* Issue 98: Process.get_cpu_times() and Process.get_memory_info now return
a namedtuple instead of a tuple.
* Issue 103: per-process opened TCP and UDP connections.
* Issue 107: add support for Windows 64 bit. (patch by cjgohlke)
* Issue 111: per-process executable name.
* Issue 113: exception messages now include process name and pid.
* Issue 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)
* Issue 117: added support for Windows 2000.
* Issue 123: psutil.cpu_percent() and psutil.Process.cpu_percent() accept a
new 'interval' parameter.
* Issue 129: per-process number of threads.
BUGFIXES
* Issue 80: fixed warnings when installing psutil with easy_install.
* Issue 81: psutil fails to compile with Visual Studio.
* Issue 94: suspend() raises OSError instead of AccessDenied.
* Issue 86: psutil didn't compile against FreeBSD 6.x.
* Issue 102: orphaned process handles obtained by using OpenProcess in C were
left behind every time Process class was instantiated.
* Issue 111: path and name Process properties report truncated or erroneous
values on UNIX.
* Issue 120: cpu_percent() always returning 100% on OS X.
* Issue 112: uid and gid properties don't change if process changes effective
user/group id at some point.
* Issue 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).
0.1.3 - 2010-03-02
------------------
NEW FEATURES
* Issue 14: per-process username
* Issue 51: per-process current working directory (Windows and Linux only)
* Issue 59: Process.is_running() is now 10 times faster
* Issue 61: added supoprt for FreeBSD 64 bit
* Issue 71: implemented suspend/resume process
* Issue 75: python 3 support
BUGFIXES
* Issue 36: process cpu_times() and memory_info() functions succeeded also for
dead processes while a NoSuchProcess exception is supposed to be raised.
* Issue 48: incorrect size for mib array defined in getcmdargs for BSD
* Issue 49: possible memory leak due to missing free() on error condition on
* Issue 50: fixed getcmdargs() memory fragmentation on BSD
* Issue 55: test_pid_4 was failing on Windows Vista
* Issue 57: some unit tests were failing on systems where no swap memory is
available
* Issue 58: is_running() is now called before kill() to make sure we are going
to kill the correct process.
* Issue 73: virtual memory size reported on OS X includes shared library size
* Issue 77: NoSuchProcess wasn't raised on Process.create_time if kill() was
used first.
0.1.2 - 2009-05-06
------------------
NEW FEATURES
* Issue 32: Per-process CPU user/kernel times
* Issue 33: Process create time
* Issue 34: Per-process CPU utilization percentage
* Issue 38: Per-process memory usage (bytes)
* Issue 41: Per-process memory utilization (percent)
* Issue 39: System uptime
* Issue 43: Total system virtual memory
* Issue 46: Total system physical memory
* Issue 44: Total system used/free virtual and physical memory
BUGFIXES
* Issue 36: NoSuchProcess not raised on Windows when accessing timing methods
* Issue 40: test_get_cpu_times() failing on FreeBSD and OS X
* Issue 42: get_memory_percent() raises AccessDenied on Windows
0.1.1 - 2009-03-06
------------------
NEW FEATURES
* Issue 4: FreeBSD support for all functions of psutil
* Issue 9: Process.uid and Process.gid now retrieve process UID and GID.
* Issue 11: Support for parent/ppid - Process.parent property returns a
Process object representing the parent process, and Process.ppid returns
the parent PID.
* Issue 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.
* Issue 21: AccessDenied exception created for raising access denied errors
from OSError or WindowsError on individual platforms.
* Issue 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).
BUGFIXES
* Issue 16: Special case for Windows' "System Idle Process" (PID 0) which
otherwise would return an "invalid parameter" exception.
* Issue 17: get_process_list() ignores NoSuchProcess and AccessDenied
exceptions during building of the list.
* Issue 22: Process(0).kill() was failing on Windows with an unset exception
* Issue 23: Special case for pid_exists(0)
* Issue 24: Process(0).kill() now raises AccessDenied exception instead of
WindowsError.
* Issue 30: psutil.get_pid_list() was returning two instances of PID 0 on OS
