Arvados

h1. Hacking Python SDK

{{toc}}

h2. Prerequisites

<pre>

sudo apt-get install python python-pip python-dev python-virtualenv libyaml-dev

</pre>

Additional prerequisites for FUSE driver:

<pre>

sudo apt-get install libattr1-dev libfuse-dev pkg-config

</pre>

h2. Get the source code

<pre>

cd

git clone https://github.com/curoverse/arvados.git

</pre>

h2. Run tests

Strategy:

# Install your local (possibly modified) client library to a virtualenv

# Run the client library test suite

# Build a client library package and install it to the virtualenv

# Install your local (possibly modified) FUSE driver to the same virtualenv

# Run the FUSE driver test suite

# Build a FUSE driver package and install it to the virtualenv

Note: The test suite brings up a Keep server and an API server to run tests against. For best results:

* Try [[Hacking Keep]] and [[Hacking API Server]] to make sure you have all the right dependencies for running the Keep and API servers.

* Make sure you have a blob_signing_key in services/api/config/application.yml
