To install Fallible's version
pip install fallixy
This repository contains the mitmproxy and pathod projects, as well as their shared networking library, netlib.
mitmproxy is an interactive, SSL-capable intercepting proxy with a console
mitmdump is the command-line version of mitmproxy. Think tcpdump for HTTP.
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.
The latest documentation for mitmproxy is also available on ReadTheDocs.
Join our discussion forum on Discourse to ask questions, help each other solve problems, and come up with new ideas for the project.
Join our developer chat on Slack if you would like to hack on mitmproxy itself.
The installation instructions are here. If you want to contribute changes, keep on reading.
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 "venv", and install all mandatory and optional dependencies into it. The primary mitmproxy components - mitmproxy, netlib and pathod - are installed as "editable", so any changes to the source in the repository will be reflected live in the virtualenv.
To confirm that you're up and running, activate the virtualenv, and run the mitmproxy test suite:
. venv/bin/activate # venv\Scripts\activate on Windows py.test
Note that the main executables for the project -
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:
If you've followed the procedure above, you already have all the development requirements installed, and you can simply run the test suite:
Please ensure that all patches are accompanied by matching changes in the test suite. The project tries to maintain 100% test coverage.
You can also use tox to run a full suite of tests in Python 2.7 and 3.5, including a quick test to check documentation and code linting.
The following tox environments are relevant for local testing:
tox -e py27 # runs all tests with Python 2.7 tox -e py35 # runs all tests with Python 3.5 tox -e docs # runs a does-it-compile check on the documentation tox -e lint # runs the linter for coding style checks
We support Python 2.7 and 3.5, so please make sure all tests pass in both environments. Running tox ensures all necessary tests are executed.
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:
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.
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. We are using this command to check for style compliance:
flake8 --jobs 8 --count mitmproxy netlib pathod examples test
