Fixed a bug? Implemented a new feature? Want to have it included in QuaZip? Here's what you need to do.

0. If you don't have a GitHub account, create one. It's ridiculously easy.

1. First, open an issue. Even if you have already fixed it. It helps to track things because instead of a commit saying “fixed this and that” you have a reference to a full issue description.

2. Next, figure out the right branch to work on. Usually it's master, but sometimes it's something different. For example, there was time when new features went to pre1.0, and master was for 0.x bugfixes only.

3. Next, send a PR (pull request). There are numerous articles how to do it, but it's not exactly intuitive, just like anything with Git, so do some research before attempting to create a PR.

Contribution guidelines

To avoid spending time on something that may never be accepted, here are some guidelines.

1. Changes should be backwards-compatible. Don't just change method names and their signatures randomly. Don't just remove deprecated features—some of them are there to keep compatibility with old Qt versions. Even Qt 4 is still supported! Unless you're working on some sort of pre2.0 branch or something like that, you should keep ABI compatibility as well! Meaning, no adding virtual functions, no changing parameter types, even if it's a source-compatible change, and a lot of other things, really.

2. If your change targets some new version of Qt, it's a very good idea to keep various #ifs in quazip_qt_compat.h, which exists for this very purpose. Don't just throw them into the code. Don't just replace deprecated things with their newer alternatives—it would break support of the old Qt versions.

3. If your changes aren't limited to a small fix or a convenience method, discussing them in the issue you just opened (if you didn't, do!) could help to achieve some agreement on what exactly is a good idea in your case.

4. Whether you're fixing a bug or adding a new feature, it's an awesome idea to add a new test in the qztest subproject. This way you make sure the bug stays fixed and the feature keeps working. This is not a mandatory requirement, however, because adding tests to a project you're not familiar with can be challenging, and it should not stop you from sending a PR.

5. It would be nice if you also update NEWS.txt with whatever changes you propose. Just add another line on top.

6. QuaZip doesn't really have any policies on PR commits. Just use common sense. Generally, it's better to keep separate things separate. If you made 2 changes, and there are 6 commits for one change and 4 for another, that's OK. Don't squash commits just to squash them. If your branch gets outdated before PR is accepted, merge or rebase—it doesn't really mater, as long as there are no conflicts.
