Hey guys, as you know I uploaded 4.04 to experimental a few months ago. 4.05 has been
"due" for a few months, I guess it will be out "any day now".
Now that the freeze is over, it would be good to start transitioning various
packages across to the new compiler version. I know roughly the process is to
build stuff in experimental, make sure they are fine, then issue a transition
request to the release team.
Usually I rebuild all the packages on my (amd64) machine. We don't
"rebuild everything once in experimental, then in unstable" as that
would entail many sourceful uploads and we want to minimize them and use
binNMUs instead.
I think we can issue the transition request for 4.04.2 now. The 4.04.x
series has been out for quite a time, and I believe broken packages must
have been fixed upstream now. I would wait a bit for the 4.05.x series.
What's your opinion on the matter?
Are there any scripts to help us do that for the hundreds of ocaml packages
that we have?
I haven't (yet) published clean scripts for the local rebuild, but the
general idea is to recompile all packages in the same order as in [1]:
build one level (using cowbuilder), put the result in a local
repository, build the next level, update the local repository with the
result, etc. and use the local repository thoughout all the process.
For the transition itself, there is no specific script or automation, we
basically follow [1]. Schedule one level of binNMU, make sure they
compile and/or upload updated packages, wait for the level to be
sufficiently completed, then go to the next level, etc.
