Allow TCL 9.0 for tests

[zuiderkwast]

Add 9.0 to list of allowed TCL versions for running the tests.

8.7 is removed. There is no such TCL version. I guess 8.7 was added in the past as an attempt to be future proof.

Fedora now comes with TCL 9.0 and we started getting failures like this: https://github.com/valkey-io/valkey/actions/runs/13147311114/job/36688160501

Which version is used in our online CI?

Which version is used in our online CI?

Most of them have 8.6. Macos has 8.5. Fedora rawhide has now only 9.0. I guess we need to support all of them.

TCL 9.0 works now. The test-fedorarawhide-jemalloc job passed.

The remaining failures are other problems. One of them is solved in #1675.

[zuiderkwast]

😱 Still fails with TLS:

version conflict for package "tcl": have 9.0.0, need 8.4

Need to solve this too.

😓 The TCL TLS package doesn't seem to support TCL 9.0 yet. See here: https://core.tcl-lang.org/tcltls/wiki/Documentation

There's a beta version of this package 2.0 which will support TCL 9.0 according to this page: https://core.tcl-lang.org/tcltls/file?name=doc/tls.html&ci=trunk

Currently, fedora rawhide includes tcltls 1.7 which is incompatible with tcl 9.0 and effectively broken. I guess they will fix it soon.

Alternatives to this PR:

• Download and build TCL 8.6, without using fedora's package repos.
• Remove Fedora rawhide from our daily scope. It is the current development verions, like our unstable branch. Maybe we shouldn't actually run it in daily?

i think we can go with this option.

I think we should not touch tls lib

[zuiderkwast]

tls 1.6 requires TCL 8.x and it rejects TCL 9.x.

If we want to use TCL 9.0, we need to use tls 2.0, which is only a beta version now. It's not yet released.

If we want to allow different TCL versions, we also need different TLS lib versions, so I think we can remove the hard-coded version requirements.

I think having it here is good as it notifies us about upcoming issues, but I agree for the moment we shouldn't be blocked on it.

@jonathanspw is looking at solving this in Fedora, probably add TCL 8 back.
