Subject Re: How can we support a faster release cadence?
Date Mon, 10 Feb 2014 10:35:42 GMT
Well I see this as something that a PMC wanting to move faster would have
to weigh up and justify to the board.

What I would like to see come out of this debate is a set of concerns that
a PMC should find a way to address before they start a fast cadence
process...

I would expect that a proposed fast cadence process would have the support
of a significant majority of both the PMC and committers.

I would expect that a proposed fast cadence process would have a mechanism
whereby interested parties could signal that they want to vote and will
need an additional time window to have the opportunity... to my mind, such
a signal would count as a -1 vote pending the actual vote.

I would expect that a short window vote would only be allowed to proceed if
there are at least 3 +1 votes and no -1 votes... if there are -1 votes I
would expect the vote to have to go to 72h

Thus if I know there will be a vote tomorrow, but I will be out of
communication due to a trans-pacific flight say, I could notify my intent
to vote... that gets treated as a -1 until I actually cast my vote... thus
the 12h shortcut is "vetoed" until my vote is cast.

Things go wrong when I arrive at my destination, and it is 3 days before
they return my laptop and let me connect to the outside world... in the
interim, 3 other PMC members have voted +1 and the release went ahead after
72h with 3x+1 and my -1

That is how I could see a short vote working for a scheduled release
process...

It would me more that the PMC says "as long as everyone is happy with
running short releases, we will make short releases... but if anyone yells
'stall the ball' then it's a 72h vote until they say 'nah it's grand go
ahead'... and any contentious votes have to go 72h anyway"
