Florian Müllner 7ff1c04c8f window: Guard minimize()
Not all windows can be minimized: X11 clients can disable the
functionality, and so do we for windows that aren't shown in
the alt-tab popup or the shell overview, so there would be no
way of getting them back.

While we make sure that we respect that ourselves (keybinding,
window menu, etc.), we don't guard meta_window_minimize(), so
clients or extensions can still minimize a window that isn't
supposed to be minimized.

That can lead to all kinds of issues, from the hidden window
being lost (as far as users are concerned) to a crash when
the minimzed window has a transient parent.

Just add an explicit check to make sure the unexpected doesn't
happen after all, and print a warning if it does.

Mutter

Mutter is a Wayland display server and X11 window manager and compositor library.

When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.

When used on top of Xorg it acts as a X11 window manager and compositing manager.

It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.

Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.

Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

Git messages

Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit. Try to always prefix commit subjects with a relevant topic, such as compositor: or clutter/actor:, and it's always better to write too much in the commit message body than too little.

Default branch

The default development branch is main. If you still have a local checkout under the old name, use:

git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
