Description Jaroslav Škarvada 2025-01-14 18:34:10 UTC

Fedora 42 will update Tcl/Tk to version 9.0. It seems your package uses Tcl or Tk as a dependency.
Please check that your package builds and works correctly with Tcl/Tk 9.0.
The effort is tracked in the bug 2337584, there is system wide change proposal [1]. I also tried to
rebuild the direct dependencies in Copr [2].

TL/DR:
- there is side tag "f42-build-side-103615"
- Tcl/Tk was bumped to version 9.0 in the side tag
- there are compat packages tcl8/tk8 in the side tag for backward compatibility
- if your package needs fixing, please fix it to build with the Tcl/Tk 9.0 or switch it to the compat tcl8/tk8
- build your package into the side tag "f42-build-side-103615" (if rebuild is not needed, e.g. the package
  just calls the Tcl shell and works with any Tcl version, ignore this step)
- close this bug

Full version:
If your package works correctly and doesn't require rebuild, please close this bug as rawhide.

If your package needs rebuild and correctly builds with the Tcl/Tk 9.0, please rebuild it with the
side-tag "f42-build-side-103615":
  $ fedpkg build --target=f42-build-side-103615
Optionally, you can regenerate the repo for others to be able to build with your package in the side-tag
(example YOUR_PKG_NVR="brltty-6.7-3"):
  $ koji wait-repo --build=$YOUR_PKG_NVR.fc42 f42-build-side-103615 --request
Close this bug as rawhide.

If your package doesn't build with the Tcl/Tk 9.0, please fix/port it. There is a Tcl/Tk 9.0 porting
guide [3]. Then build it with the side-tag "f42-build-side-103615":
  $ fedpkg build --target=f42-build-side-103615
Optionally, you can regenerate the repo for others to be able to build with your package in the side-tag,
(example YOUR_PKG_NVR="brltty-6.7-3"):
  $ koji wait-repo --build=$YOUR_PKG_NVR.fc42 f42-build-side-103615 --request
Close this bug as rawhide.

If your package cannot be ported or it's unrealistic to do it in the short time, please switch to the
compat Tcl/Tk 8 packages. In the spec file change the BuildRequires from the "tcl-devel"/"tk-devel" to
"tcl8-devel"/"tk8-devel". If your package needs explicit "Requires: tcl", you can use "Requires: tcl8".
Then build your package with the side-tag "f42-build-side-103615":
  $ fedpkg build --target=f42-build-side-103615
Optionally, you can regenerate the repo for others to be able to build with your package in the side-tag,
(example YOUR_PKG_NVR="brltty-6.7-3"):
  $ koji wait-repo --build=$YOUR_PKG_NVR.fc42 f42-build-side-103615 --request
Close this bug as rawhide.

If you update your package after resolving this bug (and before 2025-02-04), please build to the side-tag.

Components which bugzillas won't be resolved till 2025-01-31 will be switched to the compat tcl8/tk8
packages by proven packager and rebuilt into the side-tag.

Then at the turning point (2025-02-03) the side-tag will be pushed by me as an Bodhi update.

Thanks for your cooperation.

Comment 1 Jaroslav Škarvada 2025-01-15 10:42:32 UTC

Update:

There is a better way how to handle switch to compat packages, instead of build requiring tcl8-devel/tk8-devel, the following is better and backward compatible approach:
  BuildRequires: tcl-devel < 9
  BuildRequires: tk-devel < 9
The correct provides are already included in the tcl8/tk8 packages. And in a such way the package needn't be built into the side tag.

For updates please check the tracking bug 2337584.

Comment 2 Jaroslav Škarvada 2025-01-15 11:07:17 UTC

Update (auto comment):

>  BuildRequires: tcl-devel < 9
>  BuildRequires: tk-devel < 9

There is epoch, so the correct variant is:
  BuildRequires: tcl-devel < 1:9
  BuildRequires: tk-devel < 1:9

Sorry for confusion.

Comment 3 Paul Howarth 2025-01-15 20:20:33 UTC

Will the side tag rebuilds need to be done again after the mass rebuild?

Comment 4 Jaroslav Škarvada 2025-01-15 20:51:37 UTC

(In reply to Paul Howarth from comment #3)
> Will the side tag rebuilds need to be done again after the mass rebuild?

Packages using compat tcl8/tk8 doesn't require side-tag rebuild, the ABI shouldn't break. Packages using tcl/tk 9 needs to be build into side-tag. I am going to bump & rebuild everything in the side-tag before I will push the bodhi update (I initially didn't count with the mass rebuild and gcc-15 stuff).

Comment 5 Paul Howarth 2025-01-16 07:06:36 UTC

Built in side tag.
