this is not about of including everyone in mailing-group, but maintainers, and you always know who maintainers are. > This is very different from proprietary. > Also, features can be cross component / cross products / cross projects. the one who implementing the feature knows what layers he is touching, and can trigger relevant mailing-groups (this way feature owner does not have to be aware of actual layer/s maintainers) > > You can have default CC in bugzilla for the people you do know, but you must > enable other people to subscribe. i'm not talking about bagzila, but the standard process of introducing new feature, - e.g discussion cannot take place in the bugzila (it's a tool to summarise the feature, etc.), but i'd like to male sure all relevant maintainers get involved in feature design/discussion before it get written and not only when they have to review the code, and mailing-groups is a right tool for that in my view. > >> >>> you can consider a group as all people who are CC to a bug. >> >> CC'ing people manually can't guarantee that all relevant people will >> be included in the email (thread). >> >>> >>>> >>>>> (or we could create a feature mailing list). >>>> >>>> ML/MG peer feature is too much i think. >>>> >>>>> >>>>> but i do agree we could use bugzilla for tracking features per >>>>> version, if wiki isn't tracking this correctly. >>>> >>>> +1 >>>> >>>> >>>> -- >>>> >>>> Michael Pasternak >>>> RedHat, ENG-Virtualization R&D >>>> >> >> >> -- >> >> Michael Pasternak >> RedHat, ENG-Virtualization R&D >> -- Michael Pasternak RedHat, ENG-Virtualization R&D _______________________________________________ Engine-devel mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/engine-devel
