Re: [cross-project-issues-dev] Best practices on versioning
|
Perhaps this is something we can strive for incorporating into the next
Callisto (whatever it's called), meaning that if you sign up for
Callisto, you're also signing up to participate in (read: contribute to)
a unified build?

To take some heat off EMF J, we do the same in the CDT. What is best

release engineering team. In fact, I am the CDT release engineer.
Since I have many hats, I do not have much time to spend on writing
build scripts and am reluctant to change them. So for us, not using
the releng tools and simply tagging and building all the plugins every
build was easy to do, it works, and I don’t have the time right now to
change them. This is also why I am against the pack200 thing BTW.
Now as the next simultaneous release rolls around again next year, I
think this is one area where we could really reduce duplication in the
projects and streamline things. I would like to propose that we have
one release engineering team, with maybe participants from various
projects, working on one single set of build scripts and a single
simultaneous build. This would solve a lot of problems, including the
lag we have between Platform build and Callisto release, and it would
make it easier for us to line up with “best practices”. On the
negative side, there is much more chance for these builds to be busted
as API changes occur in the lower bits, but then I think that would
also force the lower bit teams and the upper bit teams to communicate
more.
Any, just a thought and sorry for not following “best practices”.

*Subject:* [cross-project-issues-dev] Best practices on versioning
I thought I'd post this here, for a "wider" education (either mine or
others :)
I've noticed one project (EMF) that appears to version all their
features and all their plugins, in the 4th place qualifier field,
to match the date and time of their builds. On the one hand, this is
nice to tell what goes-with-what in directory lists, but its counter to
"best practices" on feature and plugin versioning, right? Shouldn't
features and plugin versions (and qualifiers) change only when the
code really changes? Perhaps EMF really does change each and every one
of their features and plugins each build ...
nah, I'm sure they don't do that. So .. is this a long term plan? Just
a short term tactic?
I thought I'd ask here, publically, in case there is a reason for this
I'm not aware of ... so we can all be educated.
The problem this strategy poses is that with something like update
manager, it means users/developers might end up (re) installing code that
hasn't really changed. So .. sure EMF is a tiny project :) ... but, I
hope this doesn't become widespread practice, or the new
versioning rules won't accomplish as much as it could. For one
documented scheme on versioning rules see
http://www.eclipse.org/equinox/documents/plugin-versioning.html
We in WTP are attempting to following this too.
Do other projects have other, different schemes?
And, I hope well known, I don't mean to "pick" on EMF .. I have not
really looked at many others projects schemes, but just noticed
EMF's practice, and thought I'd ask here in the interest of
development in the open.
Thanks in advance for any clarifications.
