I
know only something short like "propose contribution to upstream module
first, then to fuel-library"; I think we need more details, and make
sure everyone knows and follows.<br><br></div></span><div>First of all, I think everybody who wants to contribute into fuel-library should know some Puppet DSL basics and also read puppet-openstack dev docs [1] and our dev docs [2]<br></div><div><br></div><div>Since we start merging upstream manifests, the most common and general rule is: upstream modules should be modified only with bugfixes and improvements everyone in the community could benefit from. And appropriate patch should be proposed to the upstream project. In other cases (like applying our own logic or settings) we should do it in our own modules or in "openstack::*" classes (fuel-library/deployment/puppet/openstack), like: openstack::compute, openstack::cinder. I think, our main goal should be: use all the community modules "as is". This is why we need to contribute to the upstream projects.<br></div><div><br></div><div></div><div>So the workflow for contributing into fuel-library should be something like this:<br><br></div><div>1. Check what module you're contributing to and where is its upstream (if any). You can check this via Modulefile located in the most of puppet modules we use:<br> fuel-library/deployment/puppet/<b>MODULE</b>/Modulefile<br></div><div>For example:<br> fuel-library/deployment/puppet/ceilometer/Modulefile<br></div><div><br></div><div>2. If the module does not have Modulefile, then it's our own module and contribution to the upstream is not needed since there's no upstream. Exception here is "openstack" module
(fuel-library/deployment/puppet/openstack) - we've modified it a lot, so
we're not going to sync it with upstream. Especially taking into account our
future granular deployment model.<br><br></div><div>3. In other cases (when module has upstream), check if the upstream version already has needed functionality and we just need to upgrade our fork of the module or back-port needed changes. If it does not, then prepare a patch to the upstream following upstream module contribution rules. For example puppet-openstack rules [1]<br><br></div><div>4. Create a gerrit review for fuel-library and put the upstream commit ID or link to github pull-request (if the module is not on stackforge) into commit message.<br></div><div></div><div></div><div><br>[1] <a href="https://wiki.openstack.org/wiki/Puppet-openstack#Developer_documentation" target="_blank">https://wiki.openstack.org/wiki/Puppet-openstack#Developer_documentation</a><br>[2] <a href="http://docs.mirantis.com/fuel-dev/develop/module_structure.html" target="_blank">http://docs.mirantis.com/fuel-dev/develop/module_structure.html</a><br><br></div><div>Regards,<br>Alex<br></div></div></div><div><div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Oct 6, 2014 at 8:17 AM, Mike Scherbakov <span dir="ltr"><<a href="mailto:mscherbakov@mirantis.com" target="_blank">mscherbakov@mirantis.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr">Hi Sergii, Alex,<div>this is an important topic.
