Hacking on Thumbor¶
So you want to contribute with thumbor? Welcome onboard!
There are a few things you’ll need in order to properly start hacking on it.
First step is to fork it and create your own clone of thumbor.
We seriously advise you to use virtualenv since it will keep your environment clean of thumbor’s dependencies and you can choose when to “turn them on”.
You’ll also need python >= 2.6 and < 3.0.
The following packages are required:
- Tornado >= 2.1.1
- pyCrypto >= 2.4.1
- pycurl >= 7.19.0
- Pillow >= 1.7.5
- redis >= 2.4.11
- pymongo >= 2.1.1
You’ll also need a recent version of OpenCV installed. When installing OpenCV, it will create a python binding. Make sure this binding is visible to your current virtualenv (if you are using it).
Other than that, you’ll also need a mongo database running, as well as a redis database running. Both are trivial to setup at modern linux or mac os systems.
Running the Tests¶
Running the tests is as easy as:
You should see the results of running your tests after an instant.
If you are experiencing “Too many open files” errors while running the tests, try increasing the number of open files per process, by running this command:
ulimit -S -n 2048

After hacking and testing your contribution, it is time to make a pull request. Make sure that your code is already integrated with the master branch of thumbor before asking for a pull request.
To add thumbor as a valid remote for your repository:
git remote add thumbor git://github.com/thumbor/thumbor.git
To merge thumbor’s master with your fork:
git pull thumbor master
If there was anything to merge, just run your tests again. If they pass, send a pull request.
