process executable from the cmdline.
BUG FIXES
* Issue 316: process exe was resolved in case it was a symlink.
* Issue 318: python 2.4 compatibility was broken.
API CHANGES

* process exe is no longer resolved in case it's a symlink.
0.6.0 - 2012-08-13
------------------
NEW FEATURES
* Issue 216: (UNIX) get_connections() UNIX sockets support.
* Issue 220: (BSD) get_connections() has been rewritten in C and no longer
requires lsof.
* Issue 222: (OSX) add support for process cwd.
* Issue 261: process extended memory info.
* Issue 295: (OSX) process executable path is now determined by asking the OS
instead of being guessed from process cmdline.
* Issue 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()
* Issue 300: examples/pmap.py script.
* Issue 301: process_iter() now yields processes sorted by their PIDs.
* Issue 302: process number of voluntary and involuntary context switches.
* Issue 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()
* Issue 305: add examples/netstat.py script.
* Issue 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 (UNIX)
- inactive (UNIX)
- buffers (BSD, Linux)
- cached (BSD, OSX)
- wired (OSX, BSD)
- shared (BSD)
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.
* Issue 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

* Issue 299: potential memory leak every time PyList_New(0) is used.

get_status() Process methods.
* Issue 305: (BSD) psutil can't compile on FreeBSD 9 due to removal of utmp.h.

which create or manipulate Python objects leading to potential memory related
errors and/or segmentation faults.
* Issue 307: (BSD) values returned by psutil.network_io_counters() are wrong.
* Issue 308: (BSD / Windows) psutil.virtmem_usage() wasn't actually returning
information about swap memory usage as it was supposed to do. It does now.
* Issue 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())

memory instead of virtual memory.
