Hello Sergio, or anyone else affected,

Accepted gtk4 into noble-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/gtk4/4.14.5+ds-0ubuntu0.6 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  Gtk4 deb package doesn't build in s390x architecture

Status in gtk4 package in Ubuntu:
  Invalid
Status in gtk4 source package in Noble:
  Fix Committed
Status in gtk4 source package in Plucky:
  Invalid
Status in gtk4 source package in Questing:
  Invalid

Bug description:
  [ Impact ]

  There are a number of gtk4 tests (build-time, and again at autopkgtest
  time) that are failing on s390x *only* when run in the combination of
  an updated mesa package (25.0.7-0ubuntu0.24.04.1) in Noble.

  The problem seems to be in the GtkWidgetPaintable widget, which isn't
  triggering the "invalidate-contents" signal. This signal should be
  triggered every time the canvas has been repainted, and it is used in
  the tests to know when it is safe to capture the rendered picture and
  compare it with the expected results.

  Setting `GSK_RENDERER=cairo` uses pure software rendering, and makes
  this work again.

  s390x is not a desktop platform, there are no desktop images for it,
  and gtk4 is not seeded in that architecture. While it would be best to
  fully understand what is making these tests fail, it's best to use
  this workaround for now in that architecture only, so that users in
  other architectures can benefit from the mesa and gtk4 updates.

  This bug affects not only the GTK4 package, but also any GTK4 app with
  build tests or autopkgtests, such as Gnome Control Center:
  https://launchpad.net/ubuntu/+source/gnome-control-
  center/1:46.7-0ubuntu0.24.04.3

  [ Test Plan ]
  The failure manifests itself in the build-time tests, which are again repeated at autopkgtest time. Therefore, the test plan consists of:
  - no build failure in any platform, and specifically s390x
  - no autopkgtest failure in any platform, and specifically s390x

  Specifically, we also don't want any change in the number of tests run
  in non-s390x architectures.

  Build time tests are not run:
  dh: command-omitted: The call to "debian/rules override_dh_auto_test" was omitted due to "DEB_BUILD_OPTIONS=nocheck"

  s390x should have no tests with a timeout result in proposed.

  [ Where problems could occur ]

  The available patch forces Cairo as the renderer in s390x, affecting all GTK4 applications. The renderer has limited capabilities vs the other OpenGL or Vulkan renderers, which may affect the look of some GTK4 applications.
  However, s390x is not a primary desktop architecture and the alternative would be non-working applications since Mesa is misbehaving in s390x.
