+=======================
+Setup and running tests
+=======================
+
+If you plan on hacking on psutil this is what you're supposed to do first:
+
+- clone the GIT repository:
+
+.. code-block:: bash
+
+ $ git clone git@github.com:giampaolo/psutil.git
+
+- install test deps and GIT hooks:
+
+.. code-block:: bash
+
+ make setup-dev-env
+
+- run tests:
+
+.. code-block:: bash
+
+ make test
+
+- bear in mind that ``make``
+ (see `Makefile <https://github.com/giampaolo/psutil/blob/master/Makefile>`_)
+ is the designated tool to run tests, build, install etc. and that it is also
+ available on Windows
+ (see `make.bat <https://github.com/giampaolo/psutil/blob/master/make.bat>`_).
+- do not use ``sudo``; ``make install`` installs psutil as a limited user in
+ "edit" mode; also ``make setup-dev-env`` installs deps as a limited user.
+- use `make help` to see the list of available commands.
+
+============
+Coding style
+============
+
+- python code strictly follows `PEP 8 <https://www.python.org/dev/peps/pep-0008/>`_
+ styling guides and this is enforced by ``make install-git-hooks``.
+- C code strictly follows `PEP 7 <https://www.python.org/dev/peps/pep-0007/>`_
+ styling guides.
+
+========
+Makefile
+========
+
+Some useful make commands:
+
+.. code-block:: bash
+
+ make install # install
+ make setup-dev-env # install useful dev libs (pyflakes, unittest2, etc.)
+ make test # run unit tests
+ make test-memleaks # run memory leak tests
+ make test-coverage # run test coverage
+ make flake8 # run PEP8 linter
+
+There are some differences between ``make`` on UNIX and Windows.
+For instance, to run a specific Python version. On UNIX:
+
+.. code-block:: bash
+
+ make test PYTHON=python3.5
+
+On Windows:
+
+.. code-block:: bat
+
+ set PYTHON=C:\python35\python.exe && make test
+
+...or:
+
+.. code-block:: bat
+
+ make -p 35 test
+
+If you want to modify psutil and run a script on the fly which uses it do
+(on UNIX):
+
+.. code-block:: bash
+
+ make test TSCRIPT=foo.py
+
+On Windows:
+
+.. code-block:: bat
+
+ set TSCRIPT=foo.py && make test
+
+====================
+Adding a new feature
+====================
+
+Usually the files involved when adding a new functionality are:
+
+.. code-block:: bash
+
+ psutil/__init__.py # main psutil namespace
+ psutil/_ps{platform}.py # python platform wrapper
+ psutil/_psutil_{platform}.c # C platform extension
+ psutil/_psutil_{platform}.h # C header file
+ psutil/tests/test_process|system.py # main test suite
+ psutil/tests/test_{platform}.py # platform specific test suite
+
+Typical process occurring when adding a new functionality (API):
+
+- define the new function in ``psutil/__init__.py``.
+- write the platform specific implementation in ``psutil/_ps{platform}.py``
+ (e.g. ``psutil/_pslinux.py``).
+- if the change requires C, write the C implementation in
+ ``psutil/_psutil_{platform}.c`` (e.g. ``psutil/_psutil_linux.c``).
+- write a generic test in ``psutil/tests/test_system.py`` or
+ ``psutil/tests/test_process.py``.
+- if possible, write a platform specific test in
+ ``psutil/tests/test_{platform}.py`` (e.g. ``test_linux.py``).
+ This usually means testing the return value of the new feature against
+ a system CLI tool.
+- update doc in ``doc/index.py``.
+- update ``HISTORY.rst``.
+- update ``README.rst`` (if necessary).
+- make a pull request.
+
+===================
+Make a pull request
+===================
+
+- fork psutil
+- create your feature branch (``git checkout -b my-new-feature``)
+- commit your changes (``git commit -am 'add some feature'``)
+- push to the branch (``git push origin my-new-feature``)
+- create a new pull request
+
+======================
+Continuous integration
+======================
+
+All of the services listed below are automatically run on ``git push``.
+
+Unit tests
+----------
+
+Tests are automatically run for every GIT push on **Linux**, **OSX** and
+**Windows** by using:
+
+- `Travis <https://travis-ci.org/giampaolo/psutil>`_ (Linux, OSX)
+- `Appveyor <https://ci.appveyor.com/project/giampaolo/psutil>`_ (Windows)
+
+Test files controlling these are
+`.travis.yml <https://github.com/giampaolo/psutil/blob/master/.travis.yml>`_
+and
+`appveyor.yml <https://github.com/giampaolo/psutil/blob/master/appveyor.yml>`_.
+Both services run psutil test suite against all supported python version
+(2.6 - 3.6).
+Two icons in the home page (README) always show the build status:
+
+.. image:: https://img.shields.io/travis/giampaolo/psutil/master.svg?maxAge=3600&label=Linux%20/%20OSX
+ :target: https://travis-ci.org/giampaolo/psutil
+ :alt: Linux tests (Travis)
+
+.. image:: https://img.shields.io/appveyor/ci/giampaolo/psutil/master.svg?maxAge=3600&label=Windows
+ :target: https://ci.appveyor.com/project/giampaolo/psutil
+ :alt: Windows tests (Appveyor)
+
+OSX, BSD, AIX and Solaris are currently tested manually (sigh!).
+
+Test coverage
+-------------
+
+Test coverage is provided by `coveralls.io <https://coveralls.io/github/giampaolo/psutil>`_,
+it is controlled via `.travis.yml <https://github.com/giampaolo/psutil/blob/master/.travis.yml>`_
+and it is updated on every git push.
+An icon in the home page (README) always shows the last coverage percentage:
+
+.. image:: https://coveralls.io/repos/giampaolo/psutil/badge.svg?branch=master&service=github
+ :target: https://coveralls.io/github/giampaolo/psutil?branch=master
+ :alt: Test coverage (coverall.io)
+
+=============
+Documentation
+=============
+
+- doc source code is written in a single file: `/docs/index.rst <https://raw.githubusercontent.com/giampaolo/psutil/master/docs/index.rst>`_.
+- it uses `RsT syntax <http://docutils.sourceforge.net/docs/user/rst/quickref.html>`_
+ and it's built with `sphinx <http://sphinx-doc.org/>`_.
+- doc can be built with ``make setup-dev-env; cd docs; make html``.
+- public doc is hosted on http://psutil.readthedocs.io/
+
+=======================
+Releasing a new version
+=======================
+
+These are notes for myself (Giampaolo):
+
+- ``make release``
+- post announce (``make print-announce``) on psutil and python-announce mailing
+ lists, twitter, g+, blog.
+
+=============
+FreeBSD notes
+=============
+
+- setup:
+
+.. code-block:: bash
+
+ pkg install python python3 gcc git vim screen bash
+ chsh -s /usr/local/bin/bash user # set bash as default shell
+
+- ``/usr/src`` contains the source codes for all installed CLI tools (grep in it).

+- #82: Cygwin (PR at #998)
+- #276: GNU/Hurd

+
+FEATURES
+========
+
+- #371: sensors_temperatures() at least for OSX.
+
+- #669: Windows / net_if_addrs(): return broadcast addr.
+
+- #550: CPU info (frequency, architecture, threads per core, cores per socket,

+
+- (Linux) locked files via /proc/locks:
+ https://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-proc-locks.html
+
+- #269: NIC rx/tx queue. 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
+ Sample code:
+ https://github.com/janmojzis/pstree/blob/master/proc_kvm.c
+
+- 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
+
+- scripts/taskmgr-gui.py (using tk).
+
+- system-wide number of open file descriptors:
+ - https://jira.hyperic.com/browse/SIGAR-30
+
+- Number of system threads.
+ - Windows: http://msdn.microsoft.com/en-us/library/windows/desktop/ms684824(v=vs.85).aspx
+
+- 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()
+ ```
+
+- 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: scripts/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.
+
+- 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.
+
+- os.times() provides 'elapsed' times (cpu_times() might).
+
+- ...also guest_time and cguest_time on Linux.
+
+- 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.

-============================
-Installing using pip on UNIX
-============================
+Install pip
+===========
+
+pip is the easiest way to install psutil.
+It is shipped by default with Python 2.7.9+ and 3.4+. For other Python versions
+you can install it manually.
+On Linux or via wget:
+
+.. code-block:: bash
+
+ wget https://bootstrap.pypa.io/get-pip.py -O - | python
-The easiest way to install psutil on UNIX is by using pip (but first you might
-need to install python header files; see later).
-First install pip::
+On OSX or via curl:
+
+.. code-block:: bash
+
+ python < <(curl -s https://bootstrap.pypa.io/get-pip.py)
+
+On Windows, `download pip <https://pip.pypa.io/en/latest/installing/>`__, open
+cmd.exe and install it:
+
+.. code-block:: bat
+
+ C:\Python27\python.exe get-pip.py
- $ wget https://bootstrap.pypa.io/get-pip.py
- $ python get-pip.py
+Permission issues (UNIX)
+========================
+
+The commands below assume you're running as root.
+If you're not or you bump into permission errors you can either:
+
+* prepend ``sudo``, e.g.:
+
+.. code-block:: bash
+
+ sudo pip install psutil
+
+* install psutil for your user only (not at system level):
-...then run::
+.. code-block:: bash
+
+ pip install --user psutil
+
+Linux
+=====
- $ pip install psutil
+Ubuntu / Debian:
+
+.. code-block:: bash
-You may need to install gcc and python header files first (see later).
+ sudo apt-get install gcc python-dev python-pip
+ pip install psutil
+
+RedHat / CentOS:
-=====================
-Installing on Windows
-=====================
+.. code-block:: bash
+
+ sudo yum install gcc python-devel python-pip
+ pip install psutil
+
+If you're on Python 3 use ``python3-dev`` and ``python3-pip`` instead.
-Just get the right installer for your Python version and architecture from:
-https://pypi.python.org/pypi/psutil/#downloads
-Since wheels installers are also available you may also use pip.
+OSX
+===
+Install `Xcode <https://developer.apple.com/downloads/?name=Xcode>`__
+first, then:
-========================================
-Compiling on Windows using Visual Studio
-========================================
+.. code-block:: bash
+
+ pip install psutil
-In order to compile psutil on Windows you'll need Visual Studio (Mingw32 is
-no longer supported). You must have the same version of Visual Studio used to compile
-your installation of Python, that is::
+Windows
+=======
+
+The easiest way to install psutil on Windows is to just use the pre-compiled
+exe/wheel installers hosted on
+`PYPI <https://pypi.python.org/pypi/psutil/#downloads>`__ via pip:
+
+.. code-block:: bat
-* Python 2.6: VS 2008
-* Python 2.7: VS 2008
-* Python 3.3, 3.4: VS 2010 (you can download it from `MS website <http://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express>`_)
-* Python 3.5: `VS 2015 UP <http://www.visualstudio.com/en-au/news/vs2015-preview-vs>`_
+ C:\Python27\python.exe -m pip install psutil
-...then run::
-
- setup.py build
+If you want to compile psutil from sources you'll need **Visual Studio**
+(Mingw32 is no longer supported):
-...or::
-
- make.bat build
+* Python 2.6, 2.7: `VS-2008 <http://www.microsoft.com/en-us/download/details.aspx?id=44266>`__
+* Python 3.3, 3.4: `VS-2010 <http://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express>`__
+* Python 3.5+: `VS-2015 <http://www.visualstudio.com/en-au/news/vs2015-preview-vs>`__
Compiling 64 bit versions of Python 2.6 and 2.7 with VS 2008 requires
-Windows SDK and .NET Framework 3.5 SP1 to be installed first.
-Once you have those run vcvars64.bat, then compile:
-http://stackoverflow.com/questions/11072521/
+`Windows SDK and .NET Framework 3.5 SP1 <https://www.microsoft.com/en-us/download/details.aspx?id=3138>`__.
+Once installed run vcvars64.bat, then you can finally compile (see
+`here <http://stackoverflow.com/questions/11072521/>`__).
+To compile / install psutil from sources on Windows run:
+
+.. code-block:: bat
+
+ make.bat build
+ make.bat install
+
+FreeBSD
+=======
+
+.. code-block:: bash
-===================
-Installing on Linux
-===================
+ pkg install python gcc
+ python -m pip install psutil
+
+OpenBSD
+=======
+
+.. code-block:: bash
+
+ export PKG_PATH="http://ftp.openbsd.org/pub/OpenBSD/`uname -r`/packages/`arch -s`/"
+ pkg_add -v python gcc
+ python -m pip install psutil
+
+NetBSD
+======
-gcc is required and so the python headers. They can easily be installed by
-using the distro package manager. For example, on Debian and Ubuntu::
+.. code-block:: bash
+
+ export PKG_PATH="ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/`uname -m`/`uname -r`/All"
+ pkg_add -v pkgin
+ pkgin install python gcc
+ python -m pip install psutil
- $ sudo apt-get install gcc python-dev
+Solaris
+=======
+
+If ``cc`` compiler is not installed create a symlink to ``gcc``:
+
+.. code-block:: bash
+
+ sudo ln -s /usr/bin/gcc /usr/local/bin/cc
-...on Redhat and CentOS::
+Install:
- $ sudo yum install gcc python-devel
+.. code-block:: bash
+
+ pkg install gcc
+ python -m pip install psutil
-Once done, you can build/install psutil with::
+Install from sources
+====================
- $ python setup.py install
+.. code-block:: bash
+
+ git clone https://github.com/giampaolo/psutil.git
+ cd psutil
+ python setup.py install
-==================
-Installing on OS X
-==================
-
-OS X installation from source will require gcc which you can obtain as part of
-the 'XcodeTools' installer from Apple. Then you can run the standard distutils
-commands.
-To build only::
-
- $ python setup.py build
-
-To install and build::
-
- $ python setup.py install
-
-
-=====================
-Installing on FreeBSD
-=====================
+Dev Guide
+=========
-The same compiler used to install Python must be present on the system in order
-to build modules using distutils. Assuming it is installed, you can build using
-the standard distutils commands.
-
-Build only::
-
- $ python setup.py build
-
-Install and build::
-
- $ python setup.py install
-
-
-========
-Makefile
-========
-
-A makefile is available for both UNIX and Windows (make.bat). It provides
-some automations for the tasks described above and might be preferred over
-using setup.py. With it you can::
-
- $ make install # just install (in --user mode)
- $ make uninstall # uninstall (needs pip)
- $ make test # run tests
- $ make clean # remove installation files
+If you plan on hacking on psutil you may want to take a look at the
+`dev guide <https://github.com/giampaolo/psutil/blob/master/DEVGUIDE.rst>`__.

+psutil (process and system utilities) is a cross-platform library for
retrieving information on **running processes** and **system utilization**
-(CPU, memory, disks, network) in Python. It is useful mainly for **system
-monitoring**, **profiling and limiting process resources** and **management of
-running processes**. It implements many functionalities offered by command line
-tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice,
-ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports
-**Linux, Windows, OSX, FreeBSD** and **Sun Solaris**, both **32-bit** and
-**64-bit** architectures, with Python versions from **2.6 to 3.5** (users of
-Python 2.4 and 2.5 may use `2.1.3 <https://pypi.python.org/pypi?name=psutil&version=2.1.3&:action=files>`__ version).

-TODO
-====
-
-A collection of ideas and notes about stuff to implement in future versions.
-"#NNN" occurrences refer to bug tracker issues at:
-https://github.com/giampaolo/psutil/issues
-
-
-HIGHER PRIORITY
-===============
-
- * OpenBSD support.
-
- * #371: CPU temperature (apparently OSX and Linux only; on Linux it requires
- lm-sensors lib).
-
- * #269: expose network ifaces RX/TW queues. 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)

About
-----
-From project's home page:
-
- psutil (python system and process utilities) is a cross-platform library for
- retrieving information on running
- **processes** and **system utilization** (CPU, memory, disks, network) in
- **Python**.
- It is useful mainly for **system monitoring**, **profiling** and **limiting
- process resources** and **management of running processes**.
- It implements many functionalities offered by command line tools
- such as: *ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice,
- ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap*.
- It currently supports **Linux, Windows, OSX, FreeBSD** and **Sun Solaris**,
- both **32-bit** and **64-bit** architectures, with Python versions from
- **2.6 to 3.4** (users of Python 2.4 and 2.5 may use `2.1.3 <https://pypi.python.org/pypi?name=psutil&version=2.1.3&:action=files>`__ version).
- `PyPy <http://pypy.org/>`__ is also known to work.

+- **Sun Solaris**
+- **AIX**
+
+...both **32-bit** and **64-bit** architectures, with Python

+Install
+-------
+
+The easiest way to install psutil is via ``pip``::
+
+ pip install psutil
+
+On UNIX this requires a C compiler (e.g. gcc) installed. On Windows pip will
+automatically retrieve a pre-compiled wheel version from
+`PYPI repository <https://pypi.python.org/pypi/psutil>`__.
+Alternatively, see more detailed
+`install <https://github.com/giampaolo/psutil/blob/master/INSTALL.rst>`_

.. function:: cpu_times(percpu=False)
- Return system CPU times as a namedtuple.
+ Return system CPU times as a named tuple.
Every attribute represents the seconds the CPU has spent in the given mode.
The attributes availability varies depending on the platform:
- - **user**
- - **system**
- - **idle**
- - **nice** *(UNIX)*
- - **iowait** *(Linux)*
- - **irq** *(Linux, FreeBSD)*
- - **softirq** *(Linux)*
- - **steal** *(Linux 2.6.11+)*
- - **guest** *(Linux 2.6.24+)*
- - **guest_nice** *(Linux 3.2.0+)*
-
- When *percpu* is ``True`` return a list of namedtuples for each logical CPU
+ - **user**: time spent by normal processes executing in user mode; on Linux
+ this also includes **guest** time
+ - **system**: time spent by processes executing in kernel mode
+ - **idle**: time spent doing nothing
+
+ Platform-specific fields:
+
+ - **nice** *(UNIX)*: time spent by niced (prioritized) processes executing in
+ user mode; on Linux this also includes **guest_nice** time
+ - **iowait** *(Linux)*: time spent waiting for I/O to complete
+ - **irq** *(Linux, BSD)*: time spent for servicing hardware interrupts
+ - **softirq** *(Linux)*: time spent for servicing software interrupts
+ - **steal** *(Linux 2.6.11+)*: time spent by other operating systems running
+ in a virtualized environment
+ - **guest** *(Linux 2.6.24+)*: time spent running a virtual CPU for guest
+ operating systems under the control of the Linux kernel
+ - **guest_nice** *(Linux 3.2.0+)*: time spent running a niced guest
+ (virtual CPU for guest operating systems under the control of the Linux
+ kernel)
+ - **interrupt** *(Windows)*: time spent for servicing hardware interrupts (
+ similar to "irq" on UNIX)
+ - **dpc** *(Windows)*: time spent servicing deferred procedure calls (DPCs);
+ DPCs are interrupts that run at a lower priority than standard interrupts.
+
+ When *percpu* is ``True`` return a list of named tuples for each logical CPU
on the system.
First element of the list refers to first CPU, second element to second CPU
and so on.
The order of the list is consistent across calls.
Example output on Linux:
>>> import psutil

+ .. versionchanged:: 4.1.0 added *interrupt* and *dpc* fields on Windows.
+
.. function:: cpu_percent(interval=None, percpu=False)
Return a float representing the current system-wide CPU utilization as a
percentage. When *interval* is > ``0.0`` compares system CPU times elapsed
before and after the interval (blocking).
When *interval* is ``0.0`` or ``None`` compares system CPU times elapsed
since last call or module import, returning immediately.
That means the first time this is called it will return a meaningless ``0.0``
value which you are supposed to ignore.
- In this case is recommended for accuracy that this function be called with at
- least ``0.1`` seconds between calls.

Processes
=========
Functions
---------
.. function:: pids()
Return a list of current running PIDs. To iterate over all processes
- :func:`process_iter()` should be preferred.
-
-.. function:: pid_exists(pid)
-
- Check whether the given PID exists in the current process list. This is
- faster than doing ``"pid in psutil.pids()"`` and should be preferred.
-
-.. function:: process_iter()
+ and avoid race conditions :func:`process_iter()` should be preferred.
+
+ >>> import psutil
+ >>> psutil.pids()
+ [1, 2, 3, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18, 19, ..., 32498]
+
+.. function:: process_iter(attrs=None, ad_value=None)
Return an iterator yielding a :class:`Process` class instance for all running
processes on the local machine.
Every instance is only created once and then cached into an internal table
which is updated every time an element is yielded.
Cached :class:`Process` instances are checked for identity so that you're
safe in case a PID has been reused by another process, in which case the
cached instance is updated.
This is should be preferred over :func:`psutil.pids()` for iterating over
processes.
Sorting order in which processes are returned is
- based on their PID. Example usage::
-
- import psutil
-
- for proc in psutil.process_iter():
- try:
- pinfo = proc.as_dict(attrs=['pid', 'name'])
- except psutil.NoSuchProcess:
- pass
- else:
- print(pinfo)
+ based on their PID.
+ *attrs* and *ad_value* have the same meaning as in :meth:`Process.as_dict()`.
+ If *attrs* is specified :meth:`Process.as_dict()` is called interanally and
+ the resulting dict is stored as a ``info`` attribute which is attached to the
+ returned :class:`Process` instances.
+ If *attrs* is an empty list it will retrieve all process info (slow).
+ Example usage::
+
+ >>> import psutil
+ >>> for proc in psutil.process_iter():
+ ... try:
+ ... pinfo = proc.as_dict(attrs=['pid', 'name', 'username'])
+ ... except psutil.NoSuchProcess:
+ ... pass
+ ... else:
+ ... print(pinfo)
+ ...
+ {'name': 'systemd', 'pid': 1, 'username': 'root'}
+ {'name': 'kthreadd', 'pid': 2, 'username': 'root'}
+ {'name': 'ksoftirqd/0', 'pid': 3, 'username': 'root'}
+ ...
+
+ More compact version using *attrs* parameter::
+
+ >>> import psutil
+ >>> for proc in psutil.process_iter(attrs=['pid', 'name', 'username']):
+ ... print(proc.info)
+ ...
+ {'name': 'systemd', 'pid': 1, 'username': 'root'}
+ {'name': 'kthreadd', 'pid': 2, 'username': 'root'}
+ {'name': 'ksoftirqd/0', 'pid': 3, 'username': 'root'}
+ ...
+
+ Example of a dict comprehensions to create a ``{pid: info, ...}`` data
+ structure::
+
+ >>> import psutil
+ >>> procs = {p.pid: p.info for p in psutil.process_iter(attrs=['name', 'username'])}
+ >>> procs
+ {1: {'name': 'systemd', 'username': 'root'},
+ 2: {'name': 'kthreadd', 'username': 'root'},
+ 3: {'name': 'ksoftirqd/0', 'username': 'root'},
+ ...}
+
+ Example showing how to filter processes by name::
+
+ >>> import psutil
+ >>> [p.info for p in psutil.process_iter(attrs=['pid', 'name']) if 'python' in p.info['name']]
+ [{'name': 'python3', 'pid': 21947},
+ {'name': 'python', 'pid': 23835}]
+
+ See also `process filtering <#filtering-and-sorting-processes>`__ section for
+ more examples.
+
+ .. versionchanged::
+ 5.3.0 added "attrs" and "ad_value" parameters.
+
+.. function:: pid_exists(pid)
+
+ Check whether the given PID exists in the current process list. This is
+ faster than doing ``pid in psutil.pids()`` and should be preferred.
.. function:: wait_procs(procs, timeout=None, callback=None)
Convenience function which waits for a list of :class:`Process` instances to
terminate. Return a ``(gone, alive)`` tuple indicating which processes are
gone and which ones are still alive. The *gone* ones will have a new
- *returncode* attribute indicating process exit status (it may be ``None``).
- ``callback`` is a function which gets called every time a process terminates
- (a :class:`Process` instance is passed as callback argument). Function will
- return as soon as all processes terminate or when timeout occurs. Tipical use
- case is:
+ *returncode* attribute indicating process exit status (will be ``None`` for
+ processes which are not our children).
+ ``callback`` is a function which gets called when one of the processes being
+ waited on is terminated and a :class:`Process` instance is passed as callback
+ argument).
+ This function will return as soon as all processes terminate or when
+ *timeout* (seconds) occurs.
+ Differently from :meth:`Process.wait` it will not raise
+ :class:`TimeoutExpired` if timeout occurs.
+ A typical use case may be:
- send SIGTERM to a list of processes
- give them some time to terminate
- send SIGKILL to those ones which are still alive
- Example::
+ Example which terminates and waits all the children of this process::
import psutil
def on_terminate(proc):
print("process {} terminated with exit code {}".format(proc, proc.returncode))
- procs = [...] # a list of Process instances
+ procs = psutil.Process().children()
for p in procs:
p.terminate()
- gone, alive = wait_procs(procs, timeout=3, callback=on_terminate)
+ gone, alive = psutil.wait_procs(procs, timeout=3, callback=on_terminate)
for p in alive:
p.kill()
Exceptions
----------
.. class:: Error()

Process class
-------------
.. class:: Process(pid=None)

+ Represents an OS process with the given *pid*.
+ If *pid* is omitted current process *pid*
+ (`os.getpid() <http://docs.python.org/library/os.html#os.getpid>`__) is used.
Raise :class:`NoSuchProcess` if *pid* does not exist.
+ On Linux *pid* can also refer to a thread ID (the *id* field returned by
+ :meth:`threads` method).
When accessing methods of this class always be prepared to catch
- :class:`NoSuchProcess` and :class:`AccessDenied` exceptions.
+ :class:`NoSuchProcess`, :class:`ZombieProcess` and :class:`AccessDenied`
+ exceptions.
`hash() <http://docs.python.org/2/library/functions.html#hash>`__ builtin can
be used against instances of this class in order to identify a process
univocally over time (the hash is determined by mixing process PID
and creation time). As such it can also be used with
`set()s <http://docs.python.org/2/library/stdtypes.html#types-set>`__.
- .. warning::
+ .. note::
+
+ In order to efficiently fetch more than one information about the process
+ at the same time, make sure to use either :meth:`as_dict` or
+ :meth:`oneshot` context manager.
+
+ .. note::
the way this class is bound to a process is uniquely via its **PID**.
- That means that if the :class:`Process` instance is old enough and
- the PID has been reused by another process in the meantime you might end up
- interacting with another process.
- The only exceptions for which process identity is pre-emptively checked
- (via PID + creation time) and guaranteed are for
+ That means that if the process terminates and the OS reuses its PID you may
+ end up interacting with another process.
+ The only exceptions for which process identity is preemptively checked
+ (via PID + creation time) is for the following methods:
:meth:`nice` (set),
:meth:`ionice` (set),
:meth:`cpu_affinity` (set),
:meth:`rlimit` (set),
:meth:`children`,
:meth:`parent`,
:meth:`suspend`
:meth:`resume`,
:meth:`send_signal`,
- :meth:`terminate`, and
- :meth:`kill`
- methods.
+ :meth:`terminate`
+ :meth:`kill`.
To prevent this problem for all other methods you can use
- :meth:`is_running()` before querying the process or use
+ :meth:`is_running()` before querying the process or
:func:`process_iter()` in case you're iterating over all processes.
+ It must be noted though that unless you deal with very "old" (inactive)
+ :class:`Process` instances this will hardly represent a problem.
+
+ .. method:: oneshot()
+
+ Utility context manager which considerably speeds up the retrieval of
+ multiple process information at the same time.
+ Internally different process info (e.g. :meth:`name`, :meth:`ppid`,
+ :meth:`uids`, :meth:`create_time`, ...) may be fetched by using the same
+ routine, but only one value is returned and the others are discarded.
+ When using this context manager the internal routine is executed once (in
+ the example below on :meth:`name()`) the value of interest is returned and
+ the others are cached.
+ The subsequent calls sharing the same internal routine will return the
+ cached value.
+ The cache is cleared when exiting the context manager block.
+ The advice is to use this every time you retrieve more than one information
+ about the process. If you're lucky, you'll get a hell of a speedup.
+ Example:
+
+ >>> import psutil
+ >>> p = psutil.Process()
+ >>> with p.oneshot():
+ ... p.name() # execute internal routine once collecting multiple info
+ ... p.cpu_times() # return cached value
+ ... p.cpu_percent() # return cached value
+ ... p.create_time() # return cached value
+ ... p.ppid() # return cached value
+ ... p.status() # return cached value
+ ...
+ >>>
+
+ Here's a list of methods which can take advantage of the speedup depending
+ on what platform you're on.
+ In the table below horizontal emtpy rows indicate what process methods can
+ be efficiently grouped together internally.
+ The last column (speedup) shows an approximation of the speedup you can get
+ if you call all the methods together (best case scenario).

+ aka "Unique Set Size", this is the memory which is unique to a process
+ and which would be freed if the process was terminated right now.
+
+ - **pss** *(Linux)*: aka "Proportional Set Size", is the amount of memory
+ shared with other processes, accounted in a way that the amount is
+ divided evenly between the processes that share it.
+ I.e. if a process has 10 MBs all to itself and 10 MBs shared with
+ another process its PSS will be 15 MBs.

+ .. method:: memory_percent(memtype="rss")
+
+ Compare process memory to total physical system memory and calculate
+ process memory utilization as a percentage.
+ *memtype* argument is a string that dictates what type of process memory
+ you want to compare against. You can choose between the named tuple field
+ names returned by :meth:`memory_info` and :meth:`memory_full_info`
+ (defaults to ``"rss"``).
+
+ .. versionchanged:: 4.0.0 added `memtype` parameter.
.. method:: memory_maps(grouped=True)
- Return process's mapped memory regions as a list of namedtuples whose
- fields are variable depending on the platform. As such, portable
- applications should rely on namedtuple's `path` and `rss` fields only.
- This method is useful to obtain a detailed representation of process
- memory usage as explained
- `here <http://bmaurer.blogspot.it/2006/03/memory-usage-with-smaps.html>`__.
- If *grouped* is ``True`` the mapped regions with the same *path* are
- grouped together and the different memory fields are summed. If *grouped*
- is ``False`` every mapped region is shown as a single entity and the
- namedtuple will also include the mapped region's address space (*addr*)
- and permission set (*perms*).
- See `examples/pmap.py <https://github.com/giampaolo/psutil/blob/master/examples/pmap.py>`__

+ already terminated immediately return ``None`` instead of raising
+ :class:`NoSuchProcess`.
+ *timeout* is expressed in seconds. If specified and the process is still
+ alive raise :class:`TimeoutExpired` exception.
+ ``timeout=0`` can be used in non-blocking apps: it will either return
+ immediately or raise :class:`TimeoutExpired`.
+ To wait for multiple processes use :func:`psutil.wait_procs()`.

+
+Unicode
+=======
+
+Starting from version 5.3.0 psutil fully supports unicode, see
+`issue #1040 <https://github.com/giampaolo/psutil/issues/1040>`__.
+The notes below apply to *any* API returning a string such as
+:meth:`Process.exe` or :meth:`Process.cwd`, including non-filesystem related
+methods such as :meth:`Process.username` or :meth:`WindowsService.description`:
+
+* all strings are encoded by using the OS filesystem encoding
+ (``sys.getfilesystemencoding()``) which varies depending on the platform
+ (e.g. "UTF-8" on OSX, "mbcs" on Win)
+* no API call is supposed to crash with ``UnicodeDecodeError``
+* instead, in case of badly encoded data returned by the OS, the following error handlers are used to replace the corrupted characters in the string:
+ * Python 3: ``sys.getfilesystemencodeerrors()`` (PY 3.6+) or
+ ``"surrogatescape"`` on POSIX and ``"replace"`` on Windows
+ * Python 2: ``"replace"``
+* on Python 2 all APIs return bytes (``str`` type), never ``unicode``
+* on Python 2, you can go back to ``unicode`` by doing:
+
+.. code-block:: python
+
+ >>> unicode(p.exe(), sys.getdefaultencoding(), errors="replace")
+
+Example which filters processes with a funky name working with both Python 2
+and 3::
+
+ # -*- coding: utf-8 -*-
+ import psutil, sys
+
+ PY3 = sys.version_info[0] == 2
+ LOOKFOR = u"ƒőő"
+ for proc in psutil.process_iter(attrs=['name']):
+ name = proc.info['name']
+ if not PY3:
+ name = unicode(name, sys.getdefaultencoding(), errors="replace")
+ if LOOKFOR == name:
+ print("process %s found" % p)
+
+Recipes
+=======
+
+Follows a collection of utilities and examples which are common but not generic
+enough to be part of the public API.
+
+Find process by name
+--------------------
+
+Check string against :meth:`Process.name()`:
+
+::
+
+ import psutil
+
+ def find_procs_by_name(name):
+ "Return a list of processes matching 'name'."
+ ls = []
+ for p in psutil.process_iter(attrs=['name']):
+ if p.info['name'] == name:
+ ls.append(p)
+ return ls
+
+A bit more advanced, check string against :meth:`Process.name()`,
+:meth:`Process.exe()` and :meth:`Process.cmdline()`:
+
+::
+
+ import os
+ import psutil
+
+ def find_procs_by_name(name):
+ "Return a list of processes matching 'name'."
+ ls = []
+ for p in psutil.process_iter(attrs=["name", "exe", "cmdline"]):
+ if name == p.info['name'] or \
+ p.info['exe'] and os.path.basename(p.info['exe']) == name or \
+ p.info['cmdline'] and p.info['cmdline'][0] == name:
+ ls.append(p)
+ return ls
+
+Kill process tree
+-----------------
+
+::
+
+ import os
+ import signal
+ import psutil
+
+ def kill_proc_tree(pid, sig=signal.SIGTERM, include_parent=True,
+ timeout=None, on_terminate=None):
+ """Kill a process tree (including grandchildren) with signal
+ "sig" and return a (gone, still_alive) tuple.
+ "on_terminate", if specified, is a callabck function which is
+ called as soon as a child terminates.
+ """
+ if pid == os.getpid():
+ raise RuntimeError("I refuse to kill myself")
+ parent = psutil.Process(pid)
+ children = parent.children(recursive=True)
+ if include_parent:
+ children.append(parent)
+ for p in children:
+ p.send_signal(sig)
+ gone, alive = psutil.wait_procs(children, timeout=timeout,
+ callback=on_terminate)
+ return (gone, alive)
+
+Terminate my children
+---------------------
+
+This may be useful in unit tests whenever sub-processes are started.
+This will help ensure that no extra children (zombies) stick around to hog
+resources.
+
+::
+
+ import psutil
+
+ def reap_children(timeout=3):
+ "Tries hard to terminate and ultimately kill all the children of this process."
+ def on_terminate(proc):
+ print("process {} terminated with exit code {}".format(proc, proc.returncode))
+
+ procs = psutil.Process().children()
+ # send SIGTERM
+ for p in procs:
+ p.terminate()
+ gone, alive = psutil.wait_procs(procs, timeout=timeout, callback=on_terminate)
+ if alive:
+ # send SIGKILL
+ for p in alive:
+ print("process {} survived SIGTERM; trying SIGKILL" % p)
+ p.kill()
+ gone, alive = psutil.wait_procs(alive, timeout=timeout, callback=on_terminate)
+ if alive:
+ # give up
+ for p in alive:
+ print("process {} survived SIGKILL; giving up" % p)

+FAQs
+====
+
+* Q: What Windows versions are supported?
+* A: From Windows **Vista** onwards, both 32 and 64 bit versions.
+ Latest binary (wheel / exe) release which supports Windows **2000**, **XP**
+ and **2003 server** is
+ `psutil 3.4.2 <https://pypi.python.org/pypi?name=psutil&version=3.4.2&:action=files>`__.
+ On such old systems psutil is no longer tested or maintained, but it can
+ still be compiled from sources (you'll need `Visual Studio <(https://github.com/giampaolo/psutil/blob/master/INSTALL.rst#windows>`__)
+ and it should "work" (more or less).
+
+----
+
+* Q: What Python versions are supported?
+* A: From 2.6 to 3.6, both 32 and 64 bit versions. Last version supporting
+ Python 2.4 and 2.5 is `psutil 2.1.3 <https://pypi.python.org/pypi?name=psutil&version=2.1.3&:action=files>`__.
+ PyPy is also known to work.
+
+----
+
+* Q: What SunOS versions are supported?
+* A: From Solaris 10 onwards.
+
+----
+
+* Q: Why do I get :class:`AccessDenied` for certain processes?
+* A: This may happen when you query processess owned by another user,
+ especially on `OSX <https://github.com/giampaolo/psutil/issues/883>`__ and
+ Windows.
+ Unfortunately there's not much you can do about this except running the
+ Python process with higher privileges.
+ On Unix you may run the the Python process as root or use the SUID bit
+ (this is the trick used by tools such as ``ps`` and ``netstat``).
+ On Windows you may run the Python process as NT AUTHORITY\\SYSTEM or install
+ the Python script as a Windows service (this is the trick used by tools
+ such as ProcessHacker).
+
+----
+
+* Q: What about load average?
+* A: psutil does not expose any load average function as it's already available
+ in python as
+ `os.getloadavg <https://docs.python.org/2/library/os.html#os.getloadavg>`__.
+
+Running tests
+=============
+
+There are two ways of running tests. If psutil is already installed use::
+
+ $ python -m psutil.tests
+

- Summary
- =======
-
- psutil (python system and process utilities) is a cross-platform library for
- retrieving information on **running processes** and **system utilization**
- (CPU, memory, disks, network) in Python. It is useful mainly for **system
- monitoring**, **profiling and limiting process resources** and **management of
- running processes**. It implements many functionalities offered by command line
- tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice,
- ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports
- **Linux, Windows, OSX, FreeBSD** and **Sun Solaris**, both **32-bit** and
- **64-bit** architectures, with Python versions from **2.6 to 3.5** (users of
- Python 2.4 and 2.5 may use `2.1.3 <https://pypi.python.org/pypi?name=psutil&version=2.1.3&:action=files>`__ version).
- `PyPy <http://pypy.org/>`__ is also known to work.

subtracting the number of 100-nanosecond period betwee 01-01-1970

+Instructions for running tests
+==============================
+
+* There are two ways of running tests. As a "user", if psutil is already
+ installed and you just want to test it works::
+
+ python -m psutil.tests --install-deps # install test deps
+ python -m psutil.tests
+
+ As a "developer", if you have a copy of the source code and you whish to hack
+ on psutil::
+
+ make setup-dev-env # install test deps (+ other things)
+ make test
+
+* To run tests on all supported Python versions install tox
+ (``pip install tox``) then run ``tox`` from within psutil root directory.
+
+* Every time a commit is pushed tests are automatically run on Travis
+ (Linux, OSX) and appveyor (Windows):
+
+ * Travis builds: https://travis-ci.org/giampaolo/psutil
+ * AppVeyor builds: https://ci.appveyor.com/project/giampaolo/psutil

+Notes about unicode handling in psutil
+======================================
+
+In psutil these are the APIs returning or dealing with a string
+('not tested' means they are not tested to deal with non-ASCII strings):
+
+* Process.cmdline()
+* Process.connections('unix')
+* Process.cwd()
+* Process.environ()
+* Process.exe()
+* Process.memory_maps()
+* Process.name()
+* Process.open_files()
+* Process.username() (not tested)
+
+* disk_io_counters() (not tested)
+* disk_partitions() (not tested)
+* disk_usage(str)
+* net_connections('unix')
+* net_if_addrs() (not tested)
+* net_if_stats() (not tested)
+* net_io_counters() (not tested)
+* sensors_fans() (not tested)
+* sensors_temperatures() (not tested)
+* users() (not tested)
+
+* WindowsService.binpath() (not tested)
+* WindowsService.description() (not tested)
+* WindowsService.display_name() (not tested)
+* WindowsService.name() (not tested)
+* WindowsService.status() (not tested)
+* WindowsService.username() (not tested)
+
+In here we create a unicode path with a funky non-ASCII name and (where
+possible) make psutil return it back (e.g. on name(), exe(), open_files(),
+etc.) and make sure that:
+
+* psutil never crashes with UnicodeDecodeError
+* the returned path matches
+
+For a detailed explanation of how psutil handles unicode see:

+There are a ton of a solutions available for validating URLs in string
+using regex, but less for searching, of which very few are accurate.
+This snippet is intended to just do the required work, and avoid
+complexities. Django Validator has pretty good regex for validation,
+but we have to find urls instead of validating them (REFERENCES [7]).
+There's always room for improvement.
+
+Method:
+* Match URLs using regex (REFERENCES [1]])
+* Some URLs need to be fixed, as they have < (or) > due to inefficient
+ regex.
+* Remove duplicates (because regex is not 100% efficient as of now).
+* Check validity of URL, using HEAD request. (HEAD to save bandwidth)
+ Uses requests module for others are painful to use. REFERENCES[9]
+ Handles redirects, http, https, ftp as well.

+A clone of iotop (http://guichaz.free.fr/iotop/) showing real time
+disk I/O statistics.
+
+It works on Linux only (FreeBSD and OSX are missing support for IO
+counters).
+It doesn't work on Windows as curses module is required.

-- The recommended way to run tests (also on Windows) is to cd into parent
- directory and run ``make test``
-
-- Dependencies for running tests:
- - python 2.6: ipaddress, mock, unittest2
- - python 2.7: ipaddress, mock
- - python 3.2: ipaddress, mock
- - python 3.3: ipaddress
- - python >= 3.4: no deps required
-
-- The main test script is ``test_psutil.py``, which also imports platform-specific
- ``_*.py`` scripts (which should be ignored).
-
-- ``test_memory_leaks.py`` looks for memory leaks into C extension modules and must
- be run separately with ``make test-memleaks``.
-
-- To run tests on all supported Python version install tox (pip install tox)
- then run ``tox``.
-
-- Every time a commit is pushed tests are automatically run on Travis:
