How to write a bug report

Please be polite, we all are humans and problems can occur.
Please add as much information as possible, for example
- client os(s) and version(s)
  - browser(s) and version(s), is the problem reproducible on different clients
  - special environments like firewalls or antivirus
- host os and version
  - npm and nodejs version
  - Logfiles if available
- steps to reproduce
- what you expected to happen
- what actually happened
Please format logfiles and code examples with markdown see github Markdown help below the issue textarea for more information.

If you send logfiles, please set the loglevel switch DEBUG in your settings.json file:

/* The log level we are using, can be: DEBUG, INFO, WARN, ERROR */
  "loglevel": "DEBUG",

The logfile location is defined in startup script or the log is directly shown in the commandline after you have started etherpad.

Important note for pull requests

Pull requests should be issued against the develop branch. We never pull directly into master.

Our goal is to iterate in small steps. Release often, release early. Evolution instead of a revolution

General goals of Etherpad

To make sure everybody is going in the same direction:

easy to install for admins and easy to use for people
easy to integrate into other apps, but also usable as standalone
lightweight and scalable
extensible, as much functionality should be extendable with plugins so changes don't have to be done in core. Also, keep it maintainable. We don't wanna end up as the monster Etherpad was!

How to work with git?

Don't work in your master branch.
Make a new branch for every feature you're working on. (This ensures that you can work you can do lots of small, independent pull requests instead of one big one with complete different features)
Don't use the online edit function of github (this only creates ugly and not working commits!)
Try to make clean commits that are easy readable (including descriptive commit messages!)
Test before you push. Sounds easy, it isn't!
Don't check in stuff that gets generated during build or runtime
Make small pull requests that are easy to review but make sure they do add value by themselves / individually

Coding style

Do write comments. (You don't have to comment every line, but if you come up with something that's a bit complex/weird, just leave a comment. Bear in mind that you will probably leave the project at some point and that other people will read your code. Undocumented huge amounts of code are worthless!)
Never ever use tabs
Indentation: JS/CSS: 2 spaces; HTML: 4 spaces
Don't overengineer. Don't try to solve any possible problem in one step, but try to solve problems as easy as possible and improve the solution over time!
Do generalize sooner or later! (if an old solution, quickly hacked together, poses more problems than it solves today, refactor it!)
Keep it compatible. Do not introduce changes to the public API, db schema or configurations too lightly. Don't make incompatible changes without good reasons!
If you do make changes, document them! (see below)
Use protocol independent urls "//"

Branching model / git workflow

see git flow http://nvie.com/posts/a-successful-git-branching-model/

`master` branch

the stable
This is the branch everyone should use for production stuff

`develop`branch

everything that is READY to go into master at some point in time
This stuff is tested and ready to go out

release branches

stuff that should go into master very soon
only bugfixes go into these (see http://nvie.com/posts/a-successful-git-branching-model/ for why)
we should not be blocking new features to develop, just because we feel that we should be releasing it to master soon. This is the situation that release branches solve/handle.

hotfix branches

fixes for bugs in master

feature branches (in your own repos)

these are the branches where you develop your features in
If it's ready to go out, it will be merged into develop

Over the time we pull features from feature branches into the develop branch. Every month we pull from develop into master. Bugs in master get fixed in hotfix branches. These branches will get merged into master AND develop. There should never be commits in master that aren't in develop

Documentation

The docs are in the doc/ folder in the git repository, so people can easily find the suitable docs for the current git revision.

Documentation should be kept up-to-date. This means, whenever you add a new API method, add a new hook or change the database model, pack the relevant changes to the docs in the same pull request.

You can build the docs e.g. produce html, using make docs. At some point in the future we will provide an online documentation. The current documentation in the github wiki should always reflect the state of master (!), since there are no docs in master, yet.

Testing

Front-end tests are found in the tests/frontend/ folder in the repository. Run them by pointing your browser to <yourdomainhere>/tests/frontend.

Back-end tests can be run from the src directory, via npm test.

Things you can help with

Etherpad is much more than software. So if you aren't a developer then worry not, there is still a LOT you can do! A big part of what we do is community engagement. You can help in the following ways

Triage bugs (applying labels) and confirming their existance
Testing fixes (simply applying them and seeing if it fixes your issue or not) - Some git experience required
Notifying large site admins of new releases
Writing Changelogs for releases
Creating Windows packages
Creating releases
Bumping dependencies periodically and checking they don't break anything
Write proposals for grants
Co-Author and Publish CVEs
Work with SFC to maintain legal side of project
Maintain TODO page - https://github.com/ether/etherpad-lite/wiki/TODO#IMPORTANT_TODOS
Replying to messages on IRC / The Mailing list / Emails
