Subject RE: [DISCUSS] Groovy 2.6 potential retirement to focus on Groovy 3.0
Date Mon, 10 Dec 2018 15:34:53 GMT
I see a monthly release of the 2.5x product – but nothing similar for version 3.  What might
be happening in the V3 world?  Given the license terms change under JDK 11, will the main
target be OpenJDK?

There was overwhelming support to drop 2.6 to focus on 3.0 and mixed feedback
on whether to do one more 2.6 alpha release or not. So, I'll go ahead and do one more
2.6 alpha release - quite possibly much less work than further discussions and it gives
us a clean end point which I am highly in favour of to reduce subsequent discussions
about what exactly was in the last alpha release.

We aren't planning to delete the branch - so it's still around if we need some
further emergency regression fixes down the track, but we aren't planning to do
any merges, so it will start to go out of sync with other branches. So even if you
have an "emergency fix" for that branch, we'd encourage you to have a discussion
on the mailing list before creating PRs against that branch.

Cheers, Paul.

option #2 for me

Hi everyone,

There was some discussion at gr8conf about how to speed up delivery of Groovy 3.0. Some of
that discussion was around the scope of what we want to include and have yet to complete in
3.0 but I won't discuss that right now.

One of the other discussion points was Groovy around 2.6. As many of you know, we have released
alpha versions of Groovy 2.6. That version is a backport of most but not all of Groovy 3.0
to JDK7 including the Parrot parser (though it isn't enabled by default). The purpose of this
version has always been to assist people/projects wanting to use the Parrot parser but who
might be stuck on JDK7. So in some sense it is an intermediate version to assist with porting
towards Groovy 3.0. While that is still a noble goal in theory, in practice, many of our users
are already on JDK8 and we have limited resources to work on many potential areas.

With that in mind, we'd like to understand the preferences in our user base for the following
two options:

Option 1: please continue releasing the best possible 2.6 even if that slows down the final
release of Groovy 3.0 and delays further work on better support for JDK9+.

Option 2: please release one more alpha of 2.6 over the next month or so which will become
the best version to use to assist porting for users stuck on JDK7 and then focus on 3.0. The
2.6 branch will essentially be retired though we will consider PRs from the community for
critical fixes.

Feedback welcome.

Cheers, Paul.
