While it wasn't stated in the proposal, and I should add it, we definitely want to do more "snapshot" like releases for testing, like what Jeremy has been doing with rawhide live snapshots. They won't be as heavily tested as even the "Alpha" release, but will still be made sure to be mostly bootable and installable. However the timing of these would depend on changes in the tree and should target significant changes and not just be a ticking clock, where as Alpha/Beta/RC/Final are time based, the other snapshots can be feature or change based. > > > [...] > > === Release Candidate and Final release === > > In order to prepare the release candidate(s) and the final release a > > final freeze is needed.

Well it pretty much is. We have to stop changes in order to finalize the release and get it out the door. I can't think of any way to stop changes but let developers prepare updates for the release (and use updates testing to get them tested!!) > New stuff can't be tested, as rawhide stands still > (I assume it's not pushed to the servers?). I'm still trying to come up with some scheme that would open a second rawhide for the next release, or someway to have a nightly tree somewhere of the pending release that is still seen and used by the majority of our testers. It's essential we get their feedback on the tree until such time as we won't take in fixes they've found. > Normal, non-critical > updates for the release (once it happens) stay updates candidates and > thus don't get much tested either.

But rawhide isn't the place to test them, as we're using rawhide as the most convenient method to get the majority of our community users to test the bits that will be the release, not the release + potential updates, the actual release. After that rawhide would be the /next/ release and also not suitable as a testing ground for updates to a release. > That's bad in > general already; but it's even more bad here, as it also create > EVR-update troubles once the release is done. How can it create EVR-update troubles? Only if maintainers push updates to previous releases before pushing them for the pending release, and even so this is not a new problem, as updates to previous releases happen all the time while the release is a static package set that quickly has "lower" nvrs than the fully updated previous release. Not a new problem, and no real solution other than using network at upgrade time to reach the released updates for the release you're upgrading to. > > > In order to accommodate a > > release candidate set plus the final release creation the freeze > > point for this should happen between the current Test3 dates and > > the final deep freeze dates. > > This proposal would IMHO be a bit easier to understand if you could > write a potential F9 schedule with release, freeze and branching > dates.

We've frequently seen feedback from them that if we just do torrent first and delay the mirrors that they'd just as likely stop mirroring us which doesn't help anybody. The only /real/ way to get releases out there quicker is to not have unstable trees all the time. If people were more careful about what they put into rawhide or more reactive to broken deps reports or did more communication when they introduce wide reaching changes we'd have less unstable trees and be able to produce functional releases in quicker fashion and be able to get them to mirrors on time. We did a pretty good job with test3, and I hope it continues with the final, and into next development cycle. > Further: I know multiple people that don't run rawhide because we > always tell everyone "once rawhide always rawhide" Where exactly do "we" tell everyone this? > and "rawhide easts > babies".

Not sure how to "give them the choice" but we certainly can document how to switch to the final release. A good "Using Rawhide" page would list this, and would fall inline with the other changes we want to make to lead to rawhide being easier and more friendly to use (and thus more used). > > (2.) create a "Fedora <N> Early Adapters Release (EAR)" which uses > the final directory structure and a Release for "early adapters". > E.g. what I mean is something like this: > > T-30 days before official release > * publish a test3 (or call it RC if you like) > * hard free for rawhide -- just like the two/three lasts week before > the release now > > T-18 days before official release > * branch rawhide and release; > * create the final directory structure on the servers with what's in > rawhide > * create and publish "Fedora <N> Early Adapters Release (EAR)" from > that tree; its yum configs point to that tree and not to rawhide > * open rawhide for release +1 -- rawhide users had enough time to > report bugs; they won't find any new bugs anymore, thus we need a > different kind of testers now which we get with that Fedora <N> EAR > > T-18 until T-7 days > * fix important stuff only like we in the past often did in the first > ten days after a Fedora release; ship that as updates > > T-7 days > * respin the tree on the servers, including all updates that happened > over the past 10 days > > T-4 days > * prepare the final release > > T-0 > * release > > = EOF = > > Just my 2 cent. I had thought about this too. It is challenging from an infrastructure standpoint to manage the bits in this way, due to the permissions typically on the release directories. However it's not impossible and could be a solution to the "second rawhide" type thing. I'm certainly open to discussing this more, but I'm not comfortable adding it to the proposal just yet. -- Jesse Keating Fedora -- All my bits are free, are yours?
