We’re always grateful for patches to Django’s code. Indeed, bug reports with associated patches will get fixed far more quickly than those without patches.
Typo fixes and trivial documentation changes¶
If you are fixing a really trivial issue, for example changing a word in the documentation, the preferred way to provide the patch is using GitHub pull requests without a Trac ticket. Trac tickets are still acceptable.
See the Working with Git and GitHub for more details on how to use pull requests.
In an open-source project with hundreds of contributors around the world, it’s important to manage communication efficiently so that work doesn’t get duplicated and contributors can be as effective as possible.
Hence, our policy is for contributors to “claim” tickets in order to let other developers know that a particular bug or feature is being worked on.
If you have identified a contribution you want to make and you’re capable of fixing it (as measured by your coding ability, knowledge of Django internals and time availability), claim it by following these steps:
- Create an account to use in our ticket system. If you have an account but have forgotten your password, you can reset it using the password reset page.
- If a ticket for this issue doesn’t exist yet, create one in our ticket tracker.
- If a ticket for this issue already exists, make sure nobody else has claimed it. To do this, look at the “Assigned to” section of the ticket. If it’s assigned to “nobody,” then it’s available to be claimed. Otherwise, somebody else is working on this ticket, and you either find another bug/feature to work on, or contact the developer working on the ticket to offer your help.
- Log into your account, if you haven’t already, by clicking “Login” in the upper right of the ticket page.
- Claim the ticket:
- click the “accept” radio button under “Action” near the bottom of the page,
- then click “Submit changes.”
The Django software foundation requests that anyone contributing more than a trivial patch to Django sign and submit a Contributor License Agreement, this ensures that the Django Software Foundation has clear license to all contributions allowing for a clear license for all users.
Ticket claimers’ responsibility¶
Once you’ve claimed a ticket, you have a responsibility to work on that ticket in a reasonably timely fashion. If you don’t have time to work on it, either unclaim it or don’t claim it in the first place!
If there’s no sign of progress on a particular claimed ticket for a week or two, another developer may ask you to relinquish the ticket claim so that it’s no longer monopolized and somebody else can claim it.
If you’ve claimed a ticket and it’s taking a long time (days or weeks) to code, keep everybody updated by posting comments on the ticket. If you don’t provide regular updates, and you don’t respond to a request for a progress report, your claim on the ticket may be revoked.
As always, more communication is better than less communication!
Which tickets should be claimed?¶
Of course, going through the steps of claiming tickets is overkill in some cases.
In the case of small changes, such as typos in the documentation or small bugs that will only take a few minutes to fix, you don’t need to jump through the hoops of claiming tickets. Just submit your patch and be done with it.
Of course, it is always acceptable, regardless whether someone has claimed it or not, to submit patches to a ticket if you happen to have a patch ready.
Make sure that any contribution you do fulfills at least the following requirements:
- The code required to fix a problem or add a feature is an essential part of a patch, but it is not the only part. A good patch should also include a regression test to validate the behavior that has been fixed and to prevent the problem from arising again. Also, if some tickets are relevant to the code that you’ve written, mention the ticket numbers in some comments in the test so that one can easily trace back the relevant discussions after your patch gets committed, and the tickets get closed.
- If the code associated with a patch adds a new feature, or modifies behavior of an existing feature, the patch should also contain documentation.
You can use either GitHub branches and pull requests or direct patches to publish your work. If you use the Git workflow, then you should announce your branch in the ticket by including a link to your branch. When you think your work is ready to be merged in create a pull request.
See the Working with Git and GitHub documentation for mode details.
You can also use patches in Trac. When using this style, follow these guidelines.
- Submit patches in the format returned by the git diff command. An exception is for code changes that are described more clearly in plain English than in code. Indentation is the most common example; it’s hard to read patches when the only difference in code is that it’s indented.
- Attach patches to a ticket in the ticket tracker, using the “attach file” button. Please don’t put the patch in the ticket description or comment unless it’s a single line patch.
- Name the patch file with a .diff extension; this will let the ticket tracker apply correct syntax highlighting, which is quite helpful.
Regardless of the way you submit your work, follow these steps.
A “non-trivial” patch is one that is more than a simple bug fix. It’s a patch that introduces Django functionality and makes some sort of design decision.
If you provide a non-trivial patch, include evidence that alternatives have been discussed on django-developers.
If you’re not sure whether your patch should be considered non-trivial, just ask.
The Closure Compiler library requires Java version 6 or higher (Java 1.6 or higher on Mac OS X. Note that Mac OS X 10.5 and earlier did not ship with Java 1.6 by default, so it may be necessary to upgrade your Java installation before the tool will be functional. Also note that even after upgrading Java, the default /usr/bin/java command may remain linked to the previous Java binary, so relinking that command may be necessary as well.)
