psutil 2.1.3 is replacing psutil 1.0.1. There are numerous bug fixes and feature enhancements in psutil worth obtaining. Source code was obtained from https://pypi.python.org/packages/source/p/psutil/psutil-2.1.3.tar.gz and uncompressed into python/psutil without modification except for the removal of the egg-info directory and the .travis.yml file. --HG-- extra : source : 697eb6db7d96dc21e817cd27a7e46ed4ab00f9bb

A collection of ideas and notes about stuff to implement in future versions.

"#NNN" occurrences refer to bug tracker issues at:

HIGHER PRIORITY
|
|
===============
|
|
|
|
* #250: net ifaces speed.
|
|
|
|
* #376: ifconfig functionalities aka psutil.net_ifaces (could be merged
|
|
with #250)
|
|
|
|
* OpenBSD support.
|
|
|
|
* #371: CPU temperature (apparently OSX and Linux only; on Linux it requires
|
|
lm-sensors lib).
|
|
|
|
* #269: expose network ifaces RX/TW queues.
|
|
|
|
* Process.threads(): thread names
|
|
|
|
* Asynchronous psutil.Popen (see http://bugs.python.org/issue1191964)
|
|
|
|
|
|
LOWER PRIORITY
|
|
==============
|
|
|
|
* #355: Android support.
|
|
|
|
* #276: GNU/Hurd support.
|
|
|
|
* #429: NetBSD support.
|
|
|
|
* DragonFlyBSD support?
|
|
|
|
* AIX support?
|
|
|
|
* examples/pidof.py (same as 'pidof' cli tool)
|
|
|
|
* examples/pstree.py (same as 'pstree' cli tool)
|
|
* threads() should also return thread names in order to implement it
|
|
|
|
* examples/taskmgr-gui.py (using tk).
|
|
|
|
* system-wide number of 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
|
|
|
|
* Doc / wiki which compares similarities between UNIX cli tools and psutil.
|
|
Example:
|
|
df -a -> psutil.disk_partitions
|
|
lsof -> psutil.Process.open_files() and psutil.Process.open_connections()
|
|
killall-> (actual script)
|
|
tty -> psutil.Process.terminal()
|
|
who -> psutil.users()
|
|
|
|
|
|
DEBATABLE
|
|
=========
|
|
|
|
* support wheels? http://pythonwheels.com/
|
|
|
|
* advanced cmdline interface exposing the whole API and providing different
|
|
kind of outputs (e.g. pprinted, colorized, json).
|
|
|
|
* [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.
|
|
|
|
* 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.cpu_times() might return
|
|
a (user, system, user_children, system_children) ntuple.
|
|
Also, os.times() provides 'elapsed' times as well.
|
|
|
|
* 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.threads() might grow an extra "id" parameter so that it can be
|
|
used as such:
|
|
|
|
>>> p = psutil.Process(os.getpid())
|
|
>>> p.threads(id=psutil.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.
|
|
|
|
Note #2: this would work with os.getpid() only.
|
|
psutil.current_thread_id() might be desirable as per issue #418 though.
|
|
|
|
* 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.
|
|
|
|
* process_iter() might grow an "attrs" parameter similar to Process.as_dict()
|
|
invoke the necessary methods and include the results into a "cache"
|
|
attribute attached to the returned Process instances so that one can avoid
|
|
catching NSP and AccessDenied:
|
|
for p in process_iter(attrs=['cpu_percent']):
|
|
print(p.cache['cpu_percent'])
|
|
This also leads questions as whether we should introduce a sorting order.
|
|
|
|
* round Process.memory_percent() result?
|
|

COMPATIBILITY BREAKAGE
|
|
======================

|
* (S) psutil.Process.nice (deprecated in 0.5.0)
|
|
* (S) get_process_list (deprecated in 0.5.0)
|
|
* (S) psutil.*mem* functions (deprecated in 0.3.0 and 0.6.0)
|
|
* (M) psutil.network_io_counters (deprecated in 1.0.0)
