0.6.2 - XXXX-XX-XX
------------------
NEW FEATURES
* #328: [Windows] process IO nice/priority support.
BUG FIXES
* #264: [Windows] use of psutil.disk_partitions() may cause a message box to
appear.
* #313: [Linux] psutil.virtual_memory() and psutil.swap_memory() can crash on
certain exotic Linux flavors having an incomplete /proc interface.
If that's the case we now set the unretrievable stats to 0 and raise a
RuntimeWarning.
* #317: [Windows] cannot set process CPU affinity above 31 cores.
* #319: [Linux] process get_memory_maps() raises KeyError 'Anonymous' on Debian
squeeze.
* #323: [OSX] disk_io_counters()'s read_time and write_time parameters were
reporting microseconds not milliseconds. (patch by Gregory Szorc)
* #333: [OSX] Leak of Mach ports on OS X (patch by [email protected])
* #337: [Linux] process methods not working because of a poor /proc
implementation will raise NotImplementedError rather than RuntimeError
and Process.as_dict() will not blow up. (patch by Curtin1060)
* #339: [FreeBSD] get_pid_list() can allocate all the memory on system.
* #341: [Linux] psutil might crash on import due to error in retrieving system
terminals map.
* #344: [FreeBSD] swap_memory() might return incorrect results due to
kvm_open(3) not being called. (patch by Jean Sebastien)
API CHANGES
* [Linux] Process methods not working because of a poor /proc implementation
will raise NotImplementedError instead of RuntimeError.
0.6.1 - 2012-08-16
------------------
NEW FEATURES
* #316: process cmdline property now makes a better job at guessing the process
executable from the cmdline.
BUG FIXES
* #316: process exe was resolved in case it was a symlink.
* #318: python 2.4 compatibility was broken.
API CHANGES
* process exe can now return an empty string instead of raising AccessDenied.
* process exe is no longer resolved in case it's a symlink.
0.6.0 - 2012-08-13
------------------
NEW FEATURES
* #216: [POSIX] get_connections() UNIX sockets support.
* #220: [FreeBSD] get_connections() has been rewritten in C and no longer
requires lsof.
* #222: [OSX] add support for process cwd.
* #261: process extended memory info.
* #295: [OSX] process executable path is now determined by asking the OS
instead of being guessed from process cmdline.
* #297: [OSX] the Process methods below were always raising AccessDenied for
any process except the current one. Now this is no longer true. Also
they are 2.5x faster.
- name
- get_memory_info()
- get_memory_percent()
- get_cpu_times()
- get_cpu_percent()
- get_num_threads()
* #300: examples/pmap.py script.
* #301: process_iter() now yields processes sorted by their PIDs.
* #302: process number of voluntary and involuntary context switches.
* #303: [Windows] the Process methods below were always raising AccessDenied
for any process not owned by current user. Now this is no longer true:
- create_time
- get_cpu_times()
- get_cpu_percent()
- get_memory_info()
- get_memory_percent()
- get_num_handles()
- get_io_counters()
* #305: add examples/netstat.py script.
* #311: system memory functions has been refactorized and rewritten and now
provide a more detailed and consistent representation of the system
memory. New psutil.virtual_memory() function provides the following
memory amounts:
- total
- available
- percent
- used
- active [POSIX]
- inactive [POSIX]
- buffers (BSD, Linux)
- cached (BSD, OSX)
- wired (OSX, BSD)
- shared [FreeBSD]
New psutil.swap_memory() provides:
- total
- used
- free
- percent
- sin (no. of bytes the system has swapped in from disk (cumulative))
- sout (no. of bytes the system has swapped out from disk (cumulative))
All old memory-related functions are deprecated.
Also two new example scripts were added: free.py and meminfo.py.
* #312: psutil.network_io_counters() namedtuple includes 4 new fields:
errin, errout dropin and dropout, reflecting the number of packets
dropped and with errors.
BUGFIXES
* #298: [OSX and BSD] memory leak in get_num_fds().
* #299: potential memory leak every time PyList_New(0) is used.
* #303: [Windows] potential heap corruption in get_num_threads() and
get_status() Process methods.
* #305: [FreeBSD] psutil can't compile on FreeBSD 9 due to removal of utmp.h.
* #306: at C level, errors are not checked when invoking Py* functions which
create or manipulate Python objects leading to potential memory related
errors and/or segmentation faults.
* #307: [FreeBSD] values returned by psutil.network_io_counters() are wrong.
* #308: [BSD / Windows] psutil.virtmem_usage() wasn't actually returning
information about swap memory usage as it was supposed to do. It does
now.
* #309: get_open_files() might not return files which can not be accessed
due to limited permissions. AccessDenied is now raised instead.
API CHANGES
* psutil.phymem_usage() is deprecated (use psutil.virtual_memory())
* psutil.virtmem_usage() is deprecated (use psutil.swap_memory())
* psutil.phymem_buffers() on Linux is deprecated (use psutil.virtual_memory())
* psutil.cached_phymem() on Linux is deprecated (use psutil.virtual_memory())
* [Windows and BSD] psutil.virtmem_usage() now returns information about swap
memory instead of virtual memory.

returned. (Patch by Amoser)
* #272: [Linux] Porcess.get_open_files() - potential race condition can lead to
unexpected NoSuchProcess exception. Also, we can get incorrect reports
of not absolutized path names.
* #275: [Linux] Process.get_io_counters() erroneously raise NoSuchProcess on
old Linux versions. Where not available it now raises
NotImplementedError.
* #286: Process.is_running() doesn't actually check whether PID has been
reused.

* #75: python 3 support
BUGFIXES
* #36: process cpu_times() and memory_info() functions succeeded also for
dead processes while a NoSuchProcess exception is supposed to be raised.
* #48: incorrect size for mib array defined in getcmdargs for BSD
* #49: possible memory leak due to missing free() on error condition on
* #50: fixed getcmdargs() memory fragmentation on BSD
* #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.
0.1.2 - 2009-05-06
------------------
NEW FEATURES
* #32: Per-process CPU user/kernel times
* #33: Process create time
* #34: Per-process CPU utilization percentage
* #38: Per-process memory usage (bytes)
* #41: Per-process memory utilization (percent)
* #39: System uptime
* #43: Total system virtual memory
* #46: Total system physical memory
* #44: Total system used/free virtual and physical memory
BUGFIXES
* #36: [Windows] NoSuchProcess not raised when accessing timing methods.
* #40: test_get_cpu_times() failing on FreeBSD and OS X.
* #42: [Windows] get_memory_percent() raises AccessDenied.
0.1.1 - 2009-03-06
------------------
NEW FEATURES
* #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).
BUGFIXES
* #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.
* #23: Special case for pid_exists(0)
* #24: [Windows] Process(0).kill() now raises AccessDenied exception instead of
WindowsError.
* #30: psutil.get_pid_list() was returning two instances of PID 0 on OS
X and FreeBSD platforms.
0.1.0 - 2009-01-27
------------------
* Initial release.
