mitmproxy
^^^^^^^^^

|travis| |appveyor| |coverage| |latest_release| |python_versions|

This repository contains the **mitmproxy** and **pathod** projects.

``mitmproxy`` is an interactive, SSL-capable intercepting proxy with a console
interface.

``mitmdump`` is the command-line version of mitmproxy. Think tcpdump for HTTP.

``mitmweb`` is a web-based interface for mitmproxy.

``pathoc`` and ``pathod`` are perverse HTTP client and server applications
designed to let you craft almost any conceivable HTTP request, including ones
that creatively violate the standards.


Documentation & Help
--------------------


General information, tutorials, and precompiled binaries can be found on the mitmproxy
and pathod websites.

Installation
------------

The installation instructions are `here <http://docs.mitmproxy.org/en/stable/install.html>`__.
If you want to contribute changes, keep on reading.


Setting Up a Development Environment
------------------------------------

To get started hacking on mitmproxy, please follow the `advanced installation`_ steps to install mitmproxy from source, but stop right before running ``pip3 install mitmproxy``. Instead, do the following:

.. code-block:: text

    git clone https://github.com/mitmproxy/mitmproxy.git
    cd mitmproxy
    ./dev.sh  # "powershell .\dev.ps1" on Windows


The *dev* script will create a `virtualenv`_ environment in a directory called
"venv3.5", and install all mandatory and optional dependencies into it. The
primary mitmproxy components - mitmproxy and pathod - are installed as
"editable", so any changes to the source in the repository will be reflected
live in the virtualenv.

The main executables for the project - ``mitmdump``, ``mitmproxy``,
``mitmweb``, ``pathod``, and ``pathoc`` - are all created within the
virtualenv. After activating the virtualenv, they will be on your $PATH, and
you can run them like any other command:

.. code-block:: text

    . venv3.5/bin/activate  # "venv\Scripts\activate" on Windows
    mitmdump --version

For convenience, the project includes an autoenv_ file (`.env`_) that
auto-activates the virtualenv when you cd into the mitmproxy directory.


Testing
-------

If you've followed the procedure above, you already have all the development
requirements installed, and you can run the full test suite (including tests for code style and documentation) with tox_:

.. code-block:: text

    tox

For speedier testing, we recommend you run `py.test`_ directly on individual test files or folders:

.. code-block:: text

    cd test/mitmproxy/addons
    py.test --cov mitmproxy.addons.anticache --looponfail test_anticache.py

As py.test does not check the code style, you probably want to run ``tox -e lint`` before committing your changes.

Please ensure that all patches are accompanied by matching changes in the test
suite. The project tries to maintain 100% test coverage and enforces this strictly for some parts of the codebase.

Documentation
-------------

The mitmproxy documentation is build using Sphinx_, which is installed
automatically if you set up a development environment as described above. After
installation, you can render the documentation like this:

.. code-block:: text

    cd docs
    make clean
    make html
    make livehtml

The last command invokes `sphinx-autobuild`_, which watches the Sphinx directory and rebuilds
the documentation when a change is detected.

Code Style
----------

Keeping to a consistent code style throughout the project makes it easier to
contribute and collaborate. Please stick to the guidelines in
`PEP8`_ and the `Google Style Guide`_ unless there's a very
good reason not to.

This is automatically enforced on every PR. If we detect a linting error, the
PR checks will fail and block merging. You can run our lint checks yourself
with the following command:

.. code-block:: text

    tox -e lint
