Getting Involved¶
#openstack-dns IRC channel¶
There is an active IRC channel at irc://oftc.net/#openstack-dns, where many of the designate contributors can be found, as well as users from various organisations.
Contributing¶
For general information on contributing to OpenStack please see the contributor guide to get started. It covers all the basics that are common to all OpenStack projects: the accounts you need, the basics of interacting with our Gerrit review system, how we communicate as a community, etc.
We welcome fixes, extensions, documentation, pretty much anything that helps improve Designate, contributing is easy & follows the standard OpenStack Gerrit workflow, if you’re looking for something to do, you could always checkout the blueprint & bug lists.
The designate git repo is available at https://opendev.org/openstack/designate, though all contributions should be done via the Gerrit review system.
Task Tracking¶
We track our tasks in Launchpad
If you’re looking for some smaller, easier work item to pick up and get started on, search for the ‘low-hanging-fruit’ tag.
Reporting a Bug¶
You found an issue and want to make sure we are aware of it? You can do so on Launchpad.
Development Environment and Developer Workflow¶
Assuming you’ve already got a working Development Environment, here’s a quick summary:
Install the git-review package to make life easier, some distros have it as native package, otherwise use pip
pip install git-review
Branch, work, & submit:
# cut a new branch, tracking master
git checkout --track -b bug/id origin/master
# work work work
git add stuff
git commit
# rebase/squash to a single commit before submitting
git rebase -i
# submit
git-review
Coding Standards¶
Designate uses the OpenStack flake8 coding standards guidelines. These are stricter than pep8, and are run by gerrit on every commit.
You can use tox to check your code locally by running
# For just flake8 tests
tox -e flake8
# For tests + flake8
tox
Example DNS Names and IP Space¶
The IANA has allocated several special purpose domains and IP blocks for use as examples in code and documentation. Where possible, these domains and IP blocks should be preferred. There are some cases where it will not be possible to follow this guidance, for example, there is currently no reserved IDN domain name.
We prefer to use these names and IP blocks to avoid causing any unexpected collateral damage to the rightful owners of the non-reserved names and IP space. For example, publishing an email address in our codebase will more than likely be picked up by spammers, while published URLs etc using non-reserved names or IP space will likely trigger search indexers etc to begin crawling.
Reserved Domains¶
Reserved DNS domains are documented here: IANA Special Use Domain Names.
Several common reserved domains:
example.com.
example.net.
example.org.
Reserved IP Space¶
Reserved IP space is documented here: IANA IPv4 Special Registry, and IANA IPv6 Special Registry.
Several common reserved IP blocks:
192.0.2.0/24
198.51.100.0/24
203.0.113.0/24
2001:db8::/32

"""<description>
mention a function :func:`foo` or a class :class:`Bar`
"""
def function(self, foo):
"""<describe what the function does>

Logging¶
See https://docs.openstack.org/oslo.i18n/latest/user/guidelines.html
# Do not use "%" string formatting
# No localization for log messages
LOG.debug("... %s", variable)
# Use named interpolation when more than one replacement is done
LOG.info("... %(key)s ...", {'key': 'value', ...})
LOG.warning("... %(key)s", {'key': 'value'})
LOG.error("... %(key)s", {'key': 'value'})
LOG.critical("... %(key)s", {'key': 'value'})
