[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH RFC 1/2] scripts: Add script to do the repetitive bits of the release process
With this script, once the main checks are out of the way, doing a
release (either an RC or the final release) should mostly be a matter
of executing a sequence of 4 commands given by the `help` function in
this script.

There's one hard-coded "default" path in here that refers to my own
directory structure. If Ian finds these scripts useful, we should
probably move that to a copy on mail.xenproject.org somewhere instead.
There are also lots of opportunities for this script to be improved,
by (for instance) implementing programmatic checks for the various
checks listed as 'manual' at the moment.
I plan to implement containerize-able tests for the first three steps
(tag, make tarball, push tag), using "dummy" paths and gpg keys. I've
made revisions to tarball-cvs-checkin-and-post which I haven't had the
opportunity to test yet; ideas for how to keep this "fresh" are
welcome.
