This file is included in README.rst from the top-level
so it is limited to pure ReST markup, not Sphinx.
gevent is a coroutine_ -based Python_ networking library that uses
`greenlet <https://greenlet.readthedocs.io>`_ to provide a high-level synchronous API on top of the `libev`_
or `libuv`_ event loop.
Features include:
* Fast event loop based on `libev`_ or `libuv`_.
* Lightweight execution units based on greenlets.
* API that re-uses concepts from the Python standard library (for
examples there are `events`_ and
`queues`_).
* `Cooperative sockets with SSL support <http://www.gevent.org/api/index.html#networking>`_
* `Cooperative DNS queries <http://www.gevent.org/dns.html>`_ performed through a threadpool,
dnspython, or c-ares.
* `Monkey patching utility <http://www.gevent.org/intro.html#monkey-patching>`_ to get 3rd party modules to become cooperative
* TCP/UDP/HTTP servers
* Subprocess support (through `gevent.subprocess`_)
* Thread pools
gevent is `inspired by eventlet`_ but features a more consistent API,
simpler implementation and better performance. Read why others `use
gevent`_ and check out the list of the `open source projects based on
gevent`_.
gevent was written by `Denis Bilenko <http://denisbilenko.com/>`_.

Installation and Requirements
===============================
.. _installation:
..
This file is included in README.rst so it is limited to plain
ReST markup, not Sphinx.
Supported Platforms
===================
`gevent 1.3`_ runs on Python 2.7 and Python 3. Releases 3.4, 3.5 and
3.6 of Python 3 are supported. (Users of older versions of Python 2
need to install gevent 1.0.x (2.5), 1.1.x (2.6) or 1.2.x (<=2.7.8);
gevent 1.2 can be installed on Python 3.3.) gevent requires the
`greenlet <https://greenlet.readthedocs.io>`_ library and will install
the `cffi`_ library by default on Windows.
gevent 1.3 also runs on PyPy 5.5 and above, although 5.9 or above is
strongly recommended. On PyPy, there are no external dependencies.
gevent is tested on Windows, OS X, and Linux, and should run on most
other Unix-like operating systems (e.g., FreeBSD, Solaris, etc.)
.. note:: On Windows using the libev backend, gevent is
limited to a maximum of 1024 open sockets due to
`limitations in libev`_. This limitation should not exist
with the default libuv backend.
Installation
============
.. note::
This section is about installing released versions of gevent
as distributed on the `Python Package Index`_
.. _Python Package Index: http://pypi.org/project/gevent
gevent and greenlet can both be installed with `pip`_, e.g., ``pip
install gevent``. Installation using `buildout
<http://docs.buildout.org/en/latest/>`_ is also supported.
On Windows, OS X, and Linux, both gevent and greenlet are
distributed as binary `wheels`_.
.. tip::
You need Pip 8.0 or later, or buildout 2.10.0 to install the
binary wheels.
.. tip::
On Linux, you'll need to install gevent from source if you wish to
use the libuv loop implementation. This is because the `manylinux1
<https://www.python.org/dev/peps/pep-0513/>`_ specification for the
distributed wheels does not support libuv. The `cffi`_ library
*must* be installed at build time.
Installing From Source
----------------------
If you are unable to use the binary wheels (for platforms where no
pre-built wheels are available or if wheel installation is disabled,
e.g., for libuv support on Linux), here are some things you need to know.
- You can install gevent from source with ``pip install --no-binary
gevent gevent``.
- You'll need a working C compiler that can build Python extensions.
On some platforms, you may need to install Python development
packages.
- Installing from source requires ``setuptools``. This is installed
automatically in virtual environments and by buildout. However,
gevent uses :pep:`496` environment markers in ``setup.py``.
Consequently, you'll need a version of setuptools newer than 25
(mid 2016) to install gevent from source; a version that's too old
will produce a ``ValueError``. Older versions of pipenv may also
`have issues installing gevent for this reason
<https://github.com/pypa/pipenv/issues/2113>`_.
- To build the libuv backend (which is required on Windows and
optional elsewhere), or the CFFI-based libev backend, you must
install `cffi`_ before attempting to install gevent on CPython (on
PyPy this step is not necessary).
Common Installation Issues
--------------------------
The following are some common installation problems and solutions for
those compiling gevent from source.
- Some Linux distributions are now mounting their temporary
directories with the ``noexec`` option. This can cause a standard
``pip install gevent`` to fail with an error like ``cannot run C
compiled programs``. One fix is to mount the temporary directory
without that option. Another may be to use the ``--build`` option to
``pip install`` to specify another directory. See `issue #570
<https://github.com/gevent/gevent/issues/570>`_ and `issue #612
<https://github.com/gevent/gevent/issues/612>`_ for examples.
- Also check for conflicts with environment variables like ``CFLAGS``. For
example, see `Library Updates <http://www.gevent.org/whatsnew_1_1.html#library-updates-label>`_.
- Users of a recent SmartOS release may need to customize the
``CPPFLAGS`` (the environment variable containing the default
options for the C preprocessor) if they are using the libev shipped
with gevent. See `Operating Systems
<http://www.gevent.org/whatsnew_1_1.html#operating-systems-label>`_
for more information.
- If you see ``ValueError: ("Expected ',' or end-of-list in", "cffi >=
1.11.5 ; sys_platform == 'win32' and platform_python_implementation
== 'CPython'", 'at', " ; sys_platform == 'win32' and
platform_python_implementation == 'CPython'")``, the version of
setuptools is too old. Install a more recent version of setuptools.
Extra Dependencies
==================
gevent has no runtime dependencies outside the standard library,
greenlet and (on some platforms) `cffi`_. However, there are a
number of additional libraries that extend gevent's functionality and
will be used if they are available.
The `psutil <https://pypi.org/project/psutil>`_ library is needed to
monitor memory usage.
`zope.event <https://pypi.org/project/zope.event>`_ is highly
recommended for configurable event support; it can be installed with
the ``events`` extra, e.g., ``pip install gevent[events]``.
`dnspython <https://pypi.org/project/dnspython>`_ is required for the
new pure-Python resolver, and on Python 2, so is `idna
<https://pypi.org/project/idna>`_. They can be installed with the
``dnspython`` extra.
Development
===========
To install the latest development version::
pip install setuptools cffi 'cython>=0.28' git+git://github.com/gevent/gevent.git#egg=gevent
.. note::
You will not be able to run gevent's test suite using that method.
To hack on gevent (using a virtualenv)::
$ git clone https://github.com/gevent/gevent.git
$ cd gevent
$ virtualenv env
$ source env/bin/activate
(env) $ pip install -r dev-requirements.txt
.. note::
The notes above about installing from source apply here as well.
The ``dev-requirements.txt`` file takes care of the library
prerequisites (CFFI, Cython), but having a working C compiler that
can create Python extensions is up to you.
Running Tests
-------------
There are a few different ways to run the tests. To simply run the
tests on one version of Python during development, begin with the
above instructions to install gevent in a virtual environment and then
run::
(env) $ python -mgevent.tests
Before submitting a pull request, it's a good idea to run the tests
across all supported versions of Python, and to check the code quality
using prospector. This is what is done on Travis CI. Locally it
can be done using tox::
pip install tox
tox
The testrunner accepts a ``--coverage`` argument to enable code
coverage metrics through the `coverage.py`_ package. That would go
something like this::
python -m gevent.tests --coverage
coverage combine
coverage html -i
<open htmlcov/index.html>
Continuous integration
----------------------
A test suite is run for every push and pull request submitted. Travis
CI is used to test on Linux, and `AppVeyor`_ runs the builds on
Windows.

.. image:: https://ci.appveyor.com/api/projects/status/q4kl21ng2yo2ixur?svg=true
:target: https://ci.appveyor.com/project/denik/gevent
Builds on Travis CI automatically submit updates to `coveralls.io`_ to
monitor test coverage.

:target: https://coveralls.io/github/gevent/gevent?branch=master
.. note:: On Debian, you will probably need ``libpythonX.Y-testsuite``
installed to run all the tests.
