Intro
=====
We would like to recognize some of the people who have been instrumental in the
development of psutil.
I'm sure we are forgetting some people (feel free to email us), but here is a
short list.
It's modeled after the Linux CREDITS file where the fields are:
name (N), e-mail (E), web-address (W), country (C), description (D), (I) issues
(issue tracker is at http://code.google.com/p/psutil/issues/list).
Really thanks to all of you.

Summary
=======
psutil is a module providing an interface for retrieving information on all
running processes and system utilization (CPU, memory, disks, network, users) in
a portable way by using Python, implementing many functionalities offered by
command line tools such as: **ps, top, df, kill, free, lsof, free, netstat,
ifconfig, nice, ionice, iostat, iotop, uptime, pidof, tty, who, taskset, pmap**.
It currently supports **Linux**, **Windows**, **OSX**, **FreeBSD**,
**Sun Solaris** both **32-bit** and **64-bit** with Python versions from **2.4**
to **3.3** by using a single code base.

TODO
====
A collection of ideas and notes about stuff to implement in future versions.
"#NNN" occurrences refer to bug tracker issues at:
https://code.google.com/p/psutil/issues/list
HIGHER PRIORITY
===============
* #387: system-wide connections (netstat).
* OpenBSD support.
* #371: CPU temperature (apparently OSX and Linux only; on Linux it requires
lm-sensors lib).
* #250: net ifaces speed.
* Process.name on Windows is slow:
http://stackoverflow.com/questions/6587036/
* Windows binary for Python 3.3 64-bit.
* #269: expose network ifaces RX/TW queues.
LOWER PRIORITY
==============
* #355: Android support.
* #276: GNU/Hurd support.
* NetBSD support?
* DranflyBSD support?
* AIX support?
* examples/pidof.py (same as 'pidof' cli tool)
* examples/pstree.py (same as 'pstree' cli tool)
* get_threads() should also return thread names in order to implement it
* examples/taskmgr-gui.py (using tk).
* system-wide # open file descriptors:
* https://jira.hyperic.com/browse/SIGAR-30
* http://www.netadmintools.com/part295.html
* Number of system threads.
* Windows: http://msdn.microsoft.com/en-us/library/windows/desktop/ms684824(v=vs.85).aspx
* #357: what CPU a process is on.
* thread names:
* https://code.google.com/p/plcrashreporter/issues/detail?id=65
DEBATABLE
=========
* [Linux]: process cgroups (http://en.wikipedia.org/wiki/Cgroups). They look
similar to prlimit() in terms of functionality but uglier (they should allow
limiting per-process network IO resources though, which is great). Needs
further reading.
* cpu_percent(): current default interval is 0.1 so that by default it will
produce a meaningful value. It represents a trap in case the user iterates
over multiple processes though, as it introduces a big slowdown.
Should it default to 0.0?
* Rename connection ntuple's fields 'local_address', 'remote_address' to
'laddr', 'raddr' (note in accordance with http://bugs.python.org/issue17675)
* Process per-cpus percent (XXX Windows only?), see:
https://groups.google.com/forum/?fromgroups#!topic/psutil/ErrKTxAbu50
* Should we expose OS constants (psutil.WINDOWS, psutil.OSX etc.)?
* Python 3.3. exposed different sched.h functions:
http://docs.python.org/dev/whatsnew/3.3.html#os
http://bugs.python.org/issue12655
http://docs.python.org/dev/library/os.html#interface-to-the-scheduler
It might be worth to take a look and figure out whether we can include some
of those in psutil.
Also, we can probably reimplement wait_pid() on POSIX which is currently
implemented as a busy-loop.
* Certain systems (XXX figure out which ones exactly) provide CPU times about
process children. On those systems Process.get_cpu_times() might return
a (user, system, user_children, system_children) ntuple.
* Enrich exception classes hierarchy on Python >= 3.3 / post PEP-3151 so that:
- NoSuchProcess inherits from ProcessLookupError
- AccessDenied inherits from PermissionError
- TimeoutExpired inherits from TimeoutError (debatable)
See: http://docs.python.org/3/library/exceptions.html#os-exceptions
* Process.get_threads() might grow an extra "id" parameter so that it can be
used as such:
>>> p = psutil.Process(pid)
>>> p.get_threads(id=psutil.get_current_thread_id())
thread(id=2539, user_time=0.03, system_time=0.02)
>>>
note: this leads to questions such as "should we have a custom NoSuchThread
exception? Also see issue #418.
* should psutil.TimeoutExpired exception have a 'msg' kwarg similar to
NoSuchProcess and AccessDenied? Not that we need it, but currently we
cannot raise a TimeoutExpired exception with a specific error string.
Side note: tests' call_until() should raise TimeoutExpired instead of
RuntimeError.
