This should probably go into - net_if_stats(). Figure out on what platforms this is supported: - Linux: yes - Others: ? - - * Process.threads(): thread names; patch for OSX available at: - https://code.google.com/p/plcrashreporter/issues/detail?id=65 - - * Asynchronous psutil.Popen (see http://bugs.python.org/issue1191964) - - * (Windows) fall back on using WMIC for Process methods returning AccessDenied - - * #613: thread names. - - * #604: emulate os.getloadavg() on Windows - - * #269: NIC rx/tx queue. - - -LOWER PRIORITY -============== - - * #355: Android support. - - * #276: GNU/Hurd support. - - * #429: NetBSD support. - - * DragonFlyBSD support? - - * AIX support? - - * 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. - - * 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 -========= - - * psutil.proc_tree() something which obtains a {pid:ppid, ...} dict for - all running processes in one shot. This can be factored out from - Process.children() and exposed as a first class function. - PROS: on Windows we can take advantage of _psutil_windows.ppid_map() - which is faster than iterating over all pids and calling ppid(). - CONS: examples/pstree.py shows this can be easily done in the user code - so maybe it's not worth the addition. - - * 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 provide CPU times about process children. On those systems - Process.cpu_times() might return a (user, system, user_children, - system_children) ntuple. - * Linux: /proc/{PID}/stat - * Solaris: pr_cutime and pr_cstime - * FreeBSD: none - * OSX: none - * Windows: none - - * ...also, os.times() provides 'elapsed' times as well. - - * ...also Linux provides guest_time and cguest_time. - - * 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? - - * #550: number of threads per core. - - * Have psutil.Process().cpu_affinity([]) be an alias for "all CPUs"? - - -COMPATIBILITY BREAKAGE -====================== - -Removals (will likely happen in 2.2): - - * (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) - * (M) local_address and remote_address Process.connection() namedtuple fields - (deprecated in 1.0.0) - - -REJECTED IDEAS -============== - -STUB |
