Our community welcomes all people interested in open source cloud
|
|
computing, and encourages you to join the `OpenStack Foundation
|
|
<https://www.openstack.org/join>`_.
|
|
|
|
If you would like to contribute to the development of OpenStack,
|
|
you must follow the steps documented at:
|
|
|
|
https://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:
|
|
|
|
https://docs.openstack.org/infra/manual/developers.html#development-workflow
|
|
|
|
(Pull requests submitted through GitHub will be ignored.)
|
|
|
|
Bugs should be filed on Storyboard now, not GitHub:
|
|
|
|
https://storyboard.openstack.org/#!/project/openstack/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 <https://wiki.openstack.org>`_, blogs, or on IRC at
|
|
``#openstack-trove`` on OFTC.

House Rules
|
|
===========
|
|
|
|
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,
|
|
* The change causes a failure in the pylint job (see pylint
|
|
section below),
|
|
* A user visible change does not provide a release note.
|
|
|
|
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.

Code Review Priority
|
|
--------------------
|
|
|
|
At the design summit in Barcelona (October 2016) we discussed code
|
|
review priority. We have a significant number of priorities for what
|
|
we want to get merged in each release. As we get closer to the release
|
|
date the time crunch will become even more acute. Therefore, we
|
|
consciously focus on taking steps to merge changes in a manner
|
|
consistent with these priorities.
|
|
|
|
All contributors to the project can help with this by reviewing the
|
|
code submitted by others, and getting them merged in a timely
|
|
manner.
|
|
|
|
Reviewing code is an important community activity and if you would
|
|
like others to prioritize the review of your changes, it is strongly
|
|
advised that you take the time to review other contributors code, and
|
|
provide useful feedback. You will notice that as you review others
|
|
code, you will not only learn more about the project and the many
|
|
supported databases, but also that others take a more proactive view
|
|
to reviewing the changes that you submit.
|
|
|
|
Merely submitting code and expecting others to review it will (most
|
|
likely) not work. If you've submitted code and you find that it isn't
|
|
getting reviewed, consider whether you've done your fair share for the
|
|
project by reviewing others code, or testing, or documenting, or
|
|
submitting significant improvements, or in one of many other ways in
|
|
which you can help advance the project.
|
|
|
|
Approving Changes
|
|
-----------------
|
|
|
|
The Trove project follows the conventions below in approving changes.
|
|
|
|
1. In general, two core reviewers must +2 a change before it can be
|
|
approved. In practice this means that coreA can +2 the change, then
|
|
coreB can +2/+A the change and it can be merged.
|
|
|
|
2. coreA and coreB should belong to different organizations.
|
|
|
|
3. For requirements changes proposed by the Proposal Bot or
|
|
translations proposed by Zanata, a single core reviewer can review
|
|
and approve the change.
|
|
|
|
NOTE:
|
|
|
|
For the remainder of the Newton release cycle, we will relax the above
|
|
conventions. These relaxations apply to the master branch only.
|
|
|
|
We will adopt a practice of lazy consensus for approving all changes
|
|
and a single core reviewer can review and approve a change. This could
|
|
be done, for example, by allowing all reviewers know that he or she
|
|
intends to approve some change or set of changes if there are no
|
|
additional negative comments by a certain time definite.
|
|
|
|
We will however still require that at least one other person review
|
|
(and +1 or +2) the change before it can be +A'ed.
|
|
|
|
Abandoning changes
|
|
------------------
|
|
|
|
At the Trove mid-cycle held in July 2016 we discussed our process for
|
|
abandoning changes and concluded that we would adopt the following
|
|
process.
|
|
|
|
1. We will take a more proactive policy towards abandoning changes
|
|
that have not been merged for a long time.
|
|
|
|
2. A list of changes proposed for abandonment will be presented at a
|
|
weekly meeting and if there is no objection, those changes will be
|
|
abandoned. If the patch sets are associated with bugs, the bugs
|
|
will be unassigned.
|
|
|
|
3. In general, changes will be proposed for abandonment if the change
|
|
being proposed has either been addressed in some other patch set,
|
|
or if the patch is not being actively maintained by the author and
|
|
there is no available volunteer who will step up to take over the
|
|
patch set.
|
|
|
|
Storyboard Bugs
|
|
---------------
|
|
|
|
Bugs should be filed on Storyboard at:
|
|
|
|
https://storyboard.openstack.org/#!/project/openstack/trove
|
|
|
|
All changes that address a Storyboard bug should include the bug in the
|
|
Commit Message using the Story and Task.
|
|
|
|
It is not required that a Storyboard bug be filed for every change.
|
|
|
|
Release Notes
|
|
-------------
|
|
|
|
All user visible changes should include a release note. Trove uses
|
|
reno to generate release notes and therefore only those release notes
|
|
that are submitted as part of a change will be included in the release
|
|
notes. The failure to add a release note for a user visible change
|
|
should be identified in review, and corrected.
|
|
|
|
If a Storyboard bug is being fixed, the release note should list the
|
|
story and task number.
|
|
|
|
For help using reno, the release notes tool, see:
|
|
|

Trove Documentation
|
|
===================
|
|
|
|
This repository also contains the Database Services API Reference.
|
|
To build the API reference, run::
|
|
|
|
$ tox -e api-ref
|
|
|
|
The generated documentation is found::
|
|
|
|
api-ref/html/index.html
|
|
|
|
Trove PyLint Failures
|
|
=====================
|
|
|
|
The Trove project uses trove-pylint (tools/trove-pylint) in the gate
|
|
and this job is intended to help catch coding errors that sometimes
|
|
may not get caught in a code review, or by the automated tests.
|
|
|
|
The gate-trove-tox-pylint jobs are run by the CI, and these invoke the
|
|
command in tools/trove-pylint.
|
|
|
|
The tool can produce false-positive notifications and therefore
|
|
supports a mechanism to provide a list of errors that are to be
|
|
ignored.
|
|
|
|
Before submitting a change, please do run
|
|
|
|
.. code-block:: bash
|
|
|
|
$ tox -e pylint
|
|
|
|
on your development environment. If this fails, you will have to
|
|
resolve all the errors before you can commit the code.
|
|
|
|
This means you either must fix the problem being identified, or
|
|
regenerate the list of ignored errors and submit that as part of your
|
|
review.
|
|
|
|
To regenerate the list of ignored errors, you run the command(s):
|
|
|
|
.. code-block:: bash
|
|
|
|
$ tox -e pylint rebuild
|
|
|
|
Warning: trove-pylint is very sensitive to the version(s) of pylint
|
|
and astroid that are installed on your system and for this reason, a
|
|
tox environment is provided that will mimic the environment that
|
|
pylint will encounter in the gate.
|
|
|
|
Pre-commit checklist
|
|
====================
|
|
|
|
Before committing code to Gerrit for review, please at least do the
|
|
following on your development system and ensure that they pass.
|
|
|
|
.. code-block:: bash
|
|
|
|
$ tox -e pep8
|
|
$ tox -e py39
|
|
$ tox -e pylint
|
|
|
|
If you are unable to get these to pass locally, it is a waste of the
|
|
CI resources to push up a change for review.
|
|
|
|
|
|
Testing
|
|
=======
|
|
|
|
Usage for integration testing
|
|
-----------------------------
|
|
|
|
If you'd like to start up a fake Trove API daemon for integration testing
|
|
with your own tool, run:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ ./tools/start-fake-mode.sh
|
|
|
|
Stop the server with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ ./tools/stop-fake-mode.sh
|
|
|
|
Tests
|
|
-----
|
|
|
|
To run all tests and PEP8, run tox, like so:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ tox
|
|
|
|
To run just the tests for Python 3.9, run:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ tox -epy39
|
|
|
|
To run just PEP8, run:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ tox -epep8
|
|
|
|
To generate a coverage report,run:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ tox -ecover
|
|
|
|
(note: on some boxes, the results may not be accurate unless you run it twice)
|
|
|
|
If you want to run only the tests in one file you can use testtools e.g.
|
|
|
|
.. code-block:: bash
|
|
|
|
$ python -m testtools.run trove.tests.unittests.python.module.path
|
|
|
|
Note that some unit tests can use an existing database. The script
|
|
``tools/test-setup.sh`` sets up the database for CI jobs and can be
|
|
used for local setup.
|
|
|
|
Is there something missing?
