Not necessarilly. Every developer must ensure to produce a quality work, with definition of "quality" being discretional. Some people fail this expectation, while others do very good. As a general rule, some people send patches to experts on the matter and they just trust their judgment, others also full-fill testing cycles by thirdy part people, others again ask for public reviews. Often this process is adapted based on the dimension of the work and the number of architectural changes it introduces. As a personal matter, for a big architectural change things I would *personally* do are: - Prepare a master-plan with experts of the matter - Post a plan (after having achived consensus) on the public mailing list for further discussions - Adjust the plan based on public feedbacks (if necessary) - Implement the plan - Ask the experts if they have objections to the implementation - Ask testers to perform some stress-testing - Ask testers to perform benchmark (if I find people interested in that) - Send out to the public mailing list for public review - Integrate suggestions - Ask testers to stress-test again - Commit I think this model in general works fairly well, but people may have different ideas on that, meaning that people may want to not involve thirdy part for testing or review. This is going to be risky and lower the quality of their work but it is their call. >> Sometimes it is useful that a limited number of developers is involved >> in initial brainstorming of some works, >> > Never. > >> but after this period >> constructive people usually ask for peer review publishing their plans >> on the mailing lists or other media. >> > Again, never.

You are forgetting one specific detail: you can always review a work *after* it entered the tree. This is something you would never do, but sometimes, when poor quality code is committed there is nothing else you can do than just raise your concern after it is in. > The callout-ng conference at BSDCan was just beautiful, it was basically: > > Speaker: "we will do this" > Audience: "how about this situation ?

I think you are referring to a specific case where a quick heads-up on a summer of code project has been presented, you cannot really believe all the technical discussion around FreeBSD evolve this way. >> If you don't see any public further discussion this may be meaning: >> a) the BSDCan meetings have been fruitless and there is no precise >> plan/roadmap/etc. >> > so not only you make it private, but it shamelessly failed... And so? I think you have a wrong point of view of what is shamelessly... I'm working on the same project since 6 months, i thought I could finish it in 1 but then I understood that in order to get the quality I was hoping I had to do more work... does it qualify as failed, according to your standard? >> b) there is still not consensus on details >> > Then the discussion should stop, public records are kept for reference > in the future.

There is not much more you can do when people don't share details and discussions automatically. Attilio -- Peace can only be achieved by understanding - A. Einstein
