How to contribute to Flawfinder
We love contributions! Here's how to do them in a way that will make everyone's lives easy.
Reporting
For normal problems, bugs, and feature requests, please file a ticket.
If you find a vulnerability, please separately send a private email to David A. Wheeler. We plan to handle vulnerabilities separately, fixing them and then telling the world. We will gladly provide credit to vulnerability reporters (unless you don't want the credit). We've never had a vulnerability report, so this is theoretical at this time.
Change process
We use "git" to track changes. To propose a change, create a fork (copy) of the repository, make your changes, and create a merge request (also called a pull request). If you're not familiar with the process, here's some documentation.
License and DCO
All proposed changes must be released under at least the project license, in this case the GNU GPL version 2 or later (GPL-2.0+).
Proposers must agree to the Developer's Certificate of Origin, aka DCO. The DCO basically says that you assert that you're legally allowed to provide the commit. Please include in your commit a statement of the form to confirm this ("git commit -s" will do this):
Signed-off-by: Your-name
You much include the DCO in your first commit proposal. If you forget occasionally, we'll assume that you just forgot, but please try to not forget.
Code Conventions
The Python code uses 2-space indents (instead of the usual 4-space indents). Do not use tabs. It is currently Python 2.7; please don't make it hard to convert to Python 3 when that eventually happens.
To make the program easy to install everywhere, the main executable is exactly one self-contained file. That involves some compromises, but for now, please keep it that way.
We aspire to eventually comply with PEP 8 other than the indentation size. In practice the code doesn't actually conform to that, but patches to improve that are generally welcome.
We're starting to use "pylint" to check for style and other problems. An easy way to install pylint is to use pip. Most python installs have pip, but if yours does not (e.g., Cygwin), install pip with:
python -m ensurepip
You may want to upgrade pip with:
pip install --upgrade pip
Finally, you can actually install pylint using:
pip install pylint
Tests
Make sure that your code passes the automated tests. Invoke tests with "make check".
It's our policy that as major new functionality is added to the software produced by the project, tests of that functionality should be added to the automated test suite.
Other
We want to eventually earn a CII Best Practices Badge.
