[platform-releng-dev] Ready for chaos and turmoil? Tuesday morning?

["David M Williams" <david_williams@xxxxxxxxxx>]

I think we are ready to "split streams"
and begin to (try) to build 4.7 and 4.6.1. 

The main things that have to be coordinated
is that all components (repositories) must create a branch from the R4_6
tag named R4_6_maintenance 
AND THEN
most or all parent pom references updated.
(All references to the main eclipse-parent pom do *have* to be updated,
but some repos have their own "internal" parents, such as all
tests bundles point to a test-parent, and the test-parent points to the
eclipse-parent-pom.  Technically the version of test-parent might
not need to be updated right away, but usually is easier and probably "more
correct" to go ahead and bump its version too). 

The parent pom in R4_6_maintenance will
change to "4.6.1" and the parent pom in master will change to
"4.7". In my experience a good "global" find and replace
can be made to work to update these, but I also know in the past some people
have ran and XSL script or similar to to it more precisely. I looked for
such a script and couldn't find it, but it might be in some old bug, or
something. 

I propose we start Tuesday morning (any
time zone) and ideally finish Tuesday evening (Eastern time) for a Tuesday
night N-build (and I-builds and M-builds to follow as soon as possible).

Once we start, then no builds will be
possible (production or Gerrit) until we all finish. 

If anyone knows of a reason this timing
will not work then please comment in Bug 496465.

Thanks,
