This section is meant for developers on the eestec.net project. It’s purpose is to guide them through the steps needed to start contributing.
First let’s look at ‘system’ libraries and applications that are normally installed with your OS packet manager, such as apt, aptitude, yum, etc.:
Then you’ll also need to install some Python specific tools:
We use the plone.api style guide so please read it and use it: http://ploneapi.readthedocs.org/en/latest/contribute/conventions.html
If you experience problems read through the following links as almost all of the above steps are required for a default Plone development environment:
If you are an OS X user, you first need a working Python implementation (the one that comes with the operating system is broken). Use https://github.com/collective/buildout.python and be happy. Also applicable to other OSes, if getting a working Python proves a challenge.
Go to your home folder or a folder you use for development and clone latest eestec.portal code:
[you@local ~]$ cd <your_work_folder> [you@local work]$ git clone https://github.com/eestec/eestec.portal.git
Now cd into the newly created directory and create an isolated python environment and build the development environment.
[you@local work]$ cd eestec.portal [you@local eestec.portal]$ make
Internally, this uses zc.buildout to build Zope and any other servers we might need, fetches all dependencies and installs them, generates config files and scripts, prepares deployment tools and much more. Read more about buildout at http://plone.org/documentation/tutorial/buildout:
While buildout is running go make some tea. When you run it for the first time it needs a couple of minutes to finish preparing your development environment. More if you have a slower Internet connection.
After make is finished your development environment is ready! You have more make command on your disposal:
[you@local eestec.portal]$ make tests # run all unit tests [you@local eestec.portal]$ make docs # generate documentation [you@local eestec.portal]$ make clean && make # start from scratch
Let’s start Zope - the application server. There are several ways to start Zope. For development purposes we’ll use the ‘foreground’ mode which starts Zope in console’s foreground so you can immediately see all debug messages and use the Python Debugger to interactively debug your code:
[you@local eestec.portal]$ bin/instance fg
Once Zope has started you need to add a Plone site. Open up a browser and point it to http://localhost:8080/@@plone-addsite?site_id=Plone. Username is admin, password is also admin. Check the eestec.portal checkbox in the Add-ons list and click Create Plone Site.
There you go, a local installation of the EESTEC portal on your laptop. Go nuts with it!
If you don’t have a ZODB to work with, as in, you are starting with a fresh install of Plone, follow this steps to add some content to your site so you can see what your code does:
Out GitHub account contains a list of open issues. Click on one that is labeled with a green entry-level tag. If the issue description says No one is assigned it means no-one is already working on it and you can claim it as your own. Click on the button next to the text and make yourself the one assigned for this issue.
Based on our Git workflow & branching model all new features must be developed in separate git branches. So if you are not doing a simple bugfix, but rather adding new features/enhancements, you should create a feature branch. This way your work is kept in an isolated place where you can receive feedback on it, improve it, etc. Once we are happy with your implementation, your branch gets merged into master at which point everyone else starts using your code.
[you@local eestec.portal]$ git checkout master # go to master branch [you@local eestec.portal]$ git checkout -b issue_17 # create a feature branch # replace 17 with the issue number you are working on # change code here [you@local eestec.portal]$ git add -p && git commit # commit my changes [you@local eestec.portal]$ git push origin issue_17 # push my branch to GitHub # at this point other can see your changes but they don't get effected by them; in other words, others can comment on your code without your code changing their development environments
Also please add your name to the Changelog
Once you are done with your work and you would like us to merge your changes into master, go to GitHub to do a pull request. Open a browser and point it to https://github.com/eestec/eestec.portal/tree/issue_<ISSUE_NUMBER>. There you should see a Pull Request button. Click on it, wrote some text what you did and anything else you would like to tell the on who will merge your branch, and finally click Send pull request. Now wait that someone comes by and merges your branch (don’t do it yourself, even if you have permissions to do so).
An example pull request text:
Please merge my branch that resolves issue #13.
