There has recently been some discussion in a recent PR about the 8.0 branch in the TCK repository. I don't intend this to be commentary on that specific thread however ...

I just want to put in my vote that we really need a maintenance plan (branching, release maintenance, etc.) for 8.x. We will need the same for releases going forward. Our experience is that vendors continue to require/discover maintenance issues on these releases long after they are finalized. (Years, maybe even decades. That is life-times in the life of many projects.)

So, I would urge that a plan needs to be in place and it probably ought to be documented in a well known location so there isn't confusion about it and there is the best probability of long term continuity. Please consider the this so the prospective maintainers, years from now, will know what to do when they come across those issues and want to apply their fix.

We do need to document the branching and maintenance plan still.

We have not yet needed to branch our last 8.0 Platform TCK release 8.0.2 but I am thinking that we do need to soon branch the 9.0.0 final release tag (yet to be created) so that we can use that to release the 5.0.1 Servlet TCK after Jakarta EE 9 is released as final and any other 9.0.* Platform TCK releases that we need to do.

I think branching makes more sense for Jakarta EE version 9 & 9.1 as we might have to work on 9.0.1 & 9.1.0 in parallel (and later merge the 9.0.1 changes to 9.1.0).

Do we really need to branch out 8.0 releases?

We can create the 8.0 branches at any time (off of the `8.0.2` tag, however, currently we only have the master branch.

With an `8.0` branch we could easily refer to the latest TCK sources under `8.0`, such as:

https://github.com/eclipse-ee4j/jakartaee-tck/tree/8.0/src/com/sun/ts/tests/jstl/spec/fmt/i18n/responseencoding

We could also refer to https://github.com/eclipse-ee4j/jakartaee-tck/tree/8.0.2/src/com/sun/ts/tests/jstl/spec/fmt/i18n/responseencoding but that might not be the latest after creating a `8.0.3` release.

I do agree though that we don't have to create a `8.0` branch now, it would just be nice to have.

If we discover maintenance issues on the current 8.0  releases (8.0.0, 8.0.1, 8.0.2) can we branch it out on a need basis to do more 8.0.x releases?

+1, I agree.


I suggest that we base the branch name on the Full Platform TCK version (major.minor):

Jakarta EE version    Platform TCK version   Branch Name
------------------    --------------------   ---------------
8                     8.0.0, 8.0.1, ...      8.0
9                     9.0.0, 9.0.1, ...      9.0
9.1                   9.1.0, 9.1.1, ...      9.1
...

Make sense?

Scott


Thanks,
