Hi All, In many cases OSS maintainers not always can be in the loop of different threads what may cause them missing important decisions being taken, As result later on during reviews of the patches they're not accepting (already implemented) features, what is causing not once for feature to be re-designed and/or delayed, what is wrong from the development cycle PoV. Therefore I'd like to suggest establishing dev-rules for the new feature implementation, what will make entire process much more easer for all of us: 1. discuss new feature on the mailing list (requirements/constraints/etc.) 2. summarise feature details in feature-doc 3. send feature-doc to review to: 3.1 ML (engine-devel) 3.2 MG (mailing group of maintainers of the relevant layers) 4. after feature-doc is accepted, 4.1 implement the feature 4.2 send it to gerrit for review to: 4.2.1 lead maintainer/s (they will review/delegate it) NOTE 3.2, 4.2.1 will require defining MGs such as: - engine-devel-core - engine-devel-ui - engine-devel-api - engine-devel-sdk - engine-devel-cli - engine-devel-vdsm ... Thoughts?

What is missing is upstream bugzilla. A feature, after initiate stage should be represented with a bug. The bug should be assigned to the right designated milestone. All document references (including versions) should be attached or referred by the bug. Dependency between features can be established using bug dependencies. Status can be acquired from buzilla at any time, progress reports should be input into bugzilla. Contact details for the feature can be acquired too, relevant and interested parties can be CCed explicitly. I guess I can add more benefits. Mailing list is good for idea initiation, but not for lifecycle management, nor for people to join at implementation phase and understand why, how and when. Having upstream bugzilla will also help us plan ahead, and manage the break the project into smaller components, to assign core developers for each.

(or we could create a feature mailing list).

but i do agree we could use bugzilla for tracking features per version, if wiki isn't tracking this correctly.

you can consider a group as all people who are CC to a bug.

Because in open source you don't know who is actually out there.

This is very different from proprietary. Also, features can be cross component / cross products / cross projects.

You can have default CC in bugzilla for the people you do know, but you must enable other people to subscribe.

I am sorry, but this is not "open" discussion. You *DO NOT* know who is interested, there can be other people that are highly valuable for a discussion and you are going to loose them.

Maintainer is not someone who is more important the contributer, he just has commit access.

If you like, a message subject convention will be more productive, "maintainer" may set trigger for a specific prefix, and there can be a documentation of this convention for features and other uses. All discussions should be made in public, this is burden but also opportunity.
