Casual contributors should feel free to read just this FAQ, and consult other chapters as needed. Where is the source code for Pacemaker?:: indexterm:[downloads] indexterm:[source code] indexterm:[git,GitHub] The https://github.com/ClusterLabs/pacemaker[source code for Pacemaker] is kept on https://github.com/[GitHub], as are all software projects under the https://github.com/ClusterLabs[ClusterLabs] umbrella. Pacemaker uses https://git-scm.com/[Git] for source code management. If you are a Git newbie, the http://schacon.github.io/git/gittutorial.html[gittutorial(7) man page] is an excellent starting point. If you're familiar with using Git from the command line, you can create a local copy of the Pacemaker source code with: `git clone https://github.com/ClusterLabs/pacemaker.git pacemaker` What are the different Git branches and repositories used for?:: indexterm:[branches] * The https://github.com/ClusterLabs/pacemaker/tree/master[master branch] is the primary branch used for development. * The https://github.com/ClusterLabs/pacemaker/tree/1.1[1.1 branch] contains the latest official release, and normally does not receive any changes. During the release cycle, it will contain release candidates for the next official release, and will receive only bug fixes. * The https://github.com/ClusterLabs/pacemaker-1.0[1.0 repository] is a frozen snapshot of the 1.0 release series, and is no longer developed. * Messages will be posted to the http://clusterlabs.org/mailman/listinfo/developers[developers@clusterlabs.org] mailing list during the release cycle, with instructions about which branches to use when submitting requests. How do I build from the source code?:: - See the - https://github.com/ClusterLabs/pacemaker/blob/master/README.markdown[README] + See https://github.com/ClusterLabs/pacemaker/blob/master/INSTALL.md[INSTALL.md] in the main checkout directory. What coding style should I follow?:: You'll be mostly fine if you simply follow the example of existing code. When unsure, see the relevant chapter of this document for language-specific recommendations. Pacemaker has grown and evolved organically over many years, so you will see much code that doesn't conform to the current guidelines. We discourage making changes solely to bring code into conformance, as any change requires developer time for review and opens the possibility of adding bugs. However, new code should follow the guidelines, and it is fine to bring lines of older code into conformance when modifying that code for other reasons. How should I format my Git commit messages?:: indexterm:[git,commit messages] See existing examples in the git log. The first line should look like +change-type: affected-code: explanation+ where +change-type+ can be +Fix+ or +Bug+ for most bug fixes, +Feature+ for new features, +Log+ for changes to log messages or handling, +Doc+ for changes to documentation or comments, or +Test+ for changes in CTS and regression tests. You will sometimes see +Low+, +Med+ (or +Mid+) and +High+ used instead for bug fixes, to indicate the severity. The important thing is that only commits with +Feature+, +Fix+, +Bug+, or +High+ will automatically be included in the change log for the next release. The +affected-code+ is the name of the component(s) being changed, for example, +crmd+ or +libcrmcommon+ (it's more free-form, so don't sweat getting it exact). The +explanation+ briefly describes the change. The git project recommends the entire summary line stay under 50 characters, but more is fine if needed for clarity. Except for the most simple and obvious of changes, the summary should be followed by a blank line and then a longer explanation of 'why' the change was made. How can I test my changes?:: Most importantly, Pacemaker has regression tests for most major components; these will automatically be run for any pull requests submitted through GitHub. Additionally, Pacemaker's Cluster Test Suite (CTS) can be used to set up a test cluster and run a wide variety of complex tests. This document will have more detail on testing in the future.
