For me it kind of does because I don’t see how we would officially provide a package and
not test it (and if we test it then it’s officially supported).
Unless we explicitly mark is as experimental so that users know that it’s not supported

Since it’s a vote I think I am -1 to support both Tomcat 8.x and 9.x at the same level (I
could change that to a -0 if everyone else agrees).
For 2 reasons:
* I feel we’re don’t have enough agent power to support so many configs - we already have
too many IMO, and each new config increases the test time exponentially.
* I’d really like that we continue having a single version for each infra server in our
docker-latest job.
So I’m proposing one of the following 2 options:
Option 1: Tomcat 8.x stays the supported version
=======
* Continue delivering XWiki on Tomcat 8.x by default. For ex the Docker image continue to
be on Tomcat 8.x, see the tags on https://hub.docker.com/_/xwiki?tab=description
* Offer a preview for Tomcat 9.x but don’t consider it as being officially supported.
This means mentioning the “preview” in the various docs.
* On the test side, this means adding it to docker-unsupported
Option 2: Tomcat 9.x becomes the latest supported version
=======
* Consider that Tomcat 9.x is now the latest version of Tomcat, i.e. make it go in the
docker-latest build (ie all tests execute on it). Executed daily.
* Consider that Tomcat 8.x is now an older version of Tomcat (but still supported) and
move all Tomcat 8.x tests to docker-all (ie only smoke tests on it). Executed weekly.
* Upgrade the official Docker image to use Tomcat 9.x. More generally upgrade all
distributions to use Tomcat 9.x. Note that we support only 1 version of Tomcat in the
Docker images we distribute.
The only question I’m asking is whether Tomcat 9.x is stable enough for using it in
production vs Tomcat 8.x (8.5.x to be precise). Note that Tomcat 8.5.x contains backports
from Tomcat 9.x AFAIK and the main difference is just the supported Servlet spec
(AFAICS).
So if we wish to make a move, I’d prefer option 2 but I don’t know if I know enough about
Tomcat 8.5.x vs Tomcat 9.x in production to make an educated decision. I’d be curious to
know if users would be ok to run Tomcat 9.x in production. Now we would still support
8.5.x so users who want to stay on Tomcat 8.5.x can.
WDYT?
Thanks

PS: I thought I saw a jira issue being closed on this topic, did I dream it or did you
anticipate the vote results? ;)
Providing a Debian package which work with Tomcat 9 does not make it
officially supported as you said. On 12 Apr 2019, at 17:53, Thomas Mortagne

So it seems there’s only an “unstable” version FTM. I would wait till there’s a “stable”
version at least. We could add it to our “unsupported” docker tests that execute once a
month though. WDYT?
No as I said there is a stable package, you just have to enable stable
backports. There is also a testing version.
What’s your need for adding support for it now, since debian doesn’t have a stable
support for it yet?

This link used to work so it’s been removed. Not sure what we should do.
