Contributing to Pegasus

This is a rough outline of what a contributor's workflow looks like:

  • Create a topic branch from where you want to base your work. This is usually master.
  • Make commits of logical units and add test case if the change fixes a bug or adds new functionality.
  • Run tests and make sure all the tests are passed.
  • Make sure your commit messages are in the proper format (see below).
  • Push your changes to a topic branch in your fork of the repository.
  • Submit a pull request.
  • Your PR must receive LGTMs from two maintainers.

Thanks for your contributions!

Format of the Commit Message

We follow a rough convention for commit messages that is designed to answer two questions: what changed and why. The subject line should feature the what and the body of the commit should describe the why.

utility: introduce rpc_holder

This is a wrapper of dsn_message_t. It manages the lifetime follow RAII.

Fix #10

The format can be described more formally as follows:

<subsystem>: <what changed>
<BLANK LINE>
<why this change was made>
<BLANK LINE>
<footer>(optional)

The first line is the subject and should be no longer than 70 characters, the second line is always blank, and other lines should be wrapped at 80 characters. This allows the message to be easier to read on GitHub as well as in various git tools.

If the change affects more than one subsystem, you can use comma to separate them like util/codec,util/types:.

If the change affects many subsystems, you can use * instead, like *:.

For the why part, if no specific reason for the change, you can use one of some generic reasons like "Improve documentation.", "Improve performance.", "Improve robustness.", "Improve test coverage."
