Contributing

Our community welcomes all people interested in open source cloud computing, and encourages you to join the OpenStack Foundation.

If you would like to contribute to the development of OpenStack, you must follow the steps documented at:

http://docs.openstack.org/infra/manual/developers.html#development-workflow

Once those steps have been completed, changes to OpenStack should be submitted for review via the Gerrit tool, following the workflow documented at:

http://docs.openstack.org/infra/manual/developers.html#development-workflow

(Pull requests submitted through GitHub will be ignored.)

Bugs should be filed on Launchpad, not GitHub:

https://bugs.launchpad.net/trove

We welcome all types of contributions, from blueprint designs to documentation to testing to deployment scripts. The best way to get involved with the community is to talk with others online or at a meetup and offer contributions through our processes, the OpenStack wiki, blogs, or on IRC at #openstack-trove on irc.freenode.net.

Code Reviews

We value your contribution in reviewing code changes submitted by others, as this helps increase the quality of the product as well. The Trove project encourages the guidelines (below).

  • A rating of +1 on a code review is indicated if:
    • It is your opinion that the change, as proposed, should be considered for merging.
  • A rating of 0 on a code review is indicated if:
    • The reason why you believe that the proposed change needs improvement is merely an opinion,
    • You have a question, or need a clarification from the author,
    • The proposed change is functional but you believe that there is a different, better, or more appropriate way in which to achieve the end result being sought by the proposed change,
    • There is an issue of some kind with the Commit Message, including violations of the Commit Message guidelines,
    • There is a typographical or formatting error in the commit message or the body of the change itself,
    • There could be improvements in the test cases provided as part of the proposed change.
  • A rating of -1 on a code review is indicated if:
    • The reason why you believe that the proposed change needs improvement is irrefutable, or it is a widely shared opinion as indicated by a number of +0 comments,
    • The subject matter of the change (not the commit message) violates some well understood OpenStack procedure(s),
    • The change contains content that is demonstrably inappropriate,
    • The test cases do not exercise the change(s) being proposed.

Some other reviewing guidelines:

  • In general, when in doubt, a rating of 0 is advised,
  • The code style guidelines accepted by the project are part of tox.ini, a violation of some other hacking rule(s), or pep8 is not a reason to -1 a change.

Trove Documentation

This repository also contains the following OpenStack manual:

  • Database Services API Reference

Prerequisites for Building the Documentation

Apache Maven must be installed to build the documentation.

To install Maven 3 for Ubuntu 12.04 and later, and Debian wheezy and later:

apt-get install maven

On Fedora 15 and later:

yum install maven3

Building

The manuals are in the apidocs directory.

To build a specific guide, look for a pom.xml file within a subdirectory, then run the mvn command in that directory. For example:

cd apidocs
mvn clean generate-sources

The generated PDF documentation file is:

apidocs/target/docbkx/webhelp/cdb-devguide/cdb-devguide-reviewer.pdf

The root of the generated HTML documentation is:

apidocs/target/docbkx/webhelp/cdb-devguide/content/index.html

Testing of changes and building of the manual

Install the python tox package and run tox from the top-level directory to use the same tests that are done as part of our Jenkins gating jobs.

If you like to run individual tests, run:

  • tox -e checkniceness - to run the niceness tests
  • tox -e checksyntax - to run syntax checks
  • tox -e checkdeletions - to check that no deleted files are referenced
  • tox -e checkbuild - to actually build the manual

tox will use the openstack-doc-tools package for execution of these tests. openstack-doc-tools has a requirement on maven for the build check.
