Subject: 30.0.50; Support webkit2gtk-4.1
Date: Thu, 09 Feb 2023 12:52:56 +0100

Gentoo is transitioning from webkit2gtk-4.0 to 4.1,
see downstream bug at <https://bugs.gentoo.org/893668>.

Would it be possible to support webkit2gtk-4.1? IIUC there should be
no API differences, so updating configure should be enough.

The patch below adds a configure option --with-webkit2gtk=VALUE that
allows to select version 4.0 or 4.1.

I have tested this with the tip of the master branch (as of today),
and it seems to build and work just fine with webkit2gtk-4.1.

I think it is ok to support both versions.  However, please make
configure search for both versions instead of making the user pick one
at configure time.

Thanks.

Are you proposing this for Emacs 29 or for Emacs 30?

Is it really necessary to ask for a specific version?  Why cannot
Emacs use the version that is installed?

Thanks.

Emacs 30, because I thought that it was to late for it to land in the
emacs-29 branch? If it could be included in Emacs 29, I would prefer
that.

That could be done as a fallback, but a configure switch is still
needed. Think of a package for a distro, which has to include the
information whether webkit2gtk-4.0 or 4.1 have to be pulled in as
a dependency. There, Emacs has to be built against a well-defined
version, even if both versions of webkit2 are installed on the build
system (for Gentoo, that will be the case for some transition time).

Should I update the patch to allow 3 values "4.0", "4.1", and "auto",
with "auto" being the default? And in the default case, should it
check for 4.0 or 4.1 first?

But if Gentoo is transitioning to this new version of webkit, wouldn't
it make sense for Emacs 29 to support that, rather than require users
to have a version of webkit that is considered outdated by Gentoo?

Yes, please.

I think 4.1 first, don't you agree?

We would have backported the patch to the Gentoo package for Emacs 29.
Including it upstream is of course preferable.

Yes. Please find the updated patch below. It applies cleanly to both
master and emacs-29.

Please make the configure script detect WebKitGTK 4.1 by default, and
fall back to 4.0.

Not many systems will have both installed at the same time, and it is
best for Emacs to use the newer version.

People who want to use the older version can specify the cflags on the
command line to configure.  There is no need for a ``--with-webkit2gtk''
option, which is not very consistent with every other library we support.
