Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.


Relevant part (hopefully):
The full build log is available from:
http://qa-logs.debian.net/2024/06/15/gtk-doc_1.34.0-1_unstable.log

All bugs filed during this archive rebuild are listed at:
https://bugs.debian.org/cgi-bin/pkgreport.cgi?tag=ftbfs-20240615;users=lucas@debian.org
or:

A list of current common problems and possible solutions is available at
http://wiki.debian.org/qa.debian.org/FTBFS . You're welcome to contribute!

If you reassign this bug to another package, please mark it as 'affects'-ing
this package. See https://www.debian.org/Bugs/server-control#affects

If you fail to reproduce this, please provide a build log and diff it with mine
so that we can identify if something relevant changed in the meantime.

gtk-doc also FTBFS in reproducible-builds from approximately 2024-05-30
to 2024-09-24 in unstable (but not in trixie, meaning the bug was in
something other than gtk-doc) but now builds successfully:
https://tests.reproducible-builds.org/debian/history/gtk-doc.html
The logs aren't kept, so there's no proof that this was specifically
this bug, but it seems likely.

Hence, I suggest closing this bug.

Control: retitle -1 gtk-doc: FTBFS with libxml2 2.12.x: XInclude error : could not load ../../examples/gobject.c
Control: severity -1 important

Actually I'm going to downgrade this to non-RC but not close it, because
the combination of the error message and the timing strongly suggests
that this was triggered by the update of libxml2 from 2.9.x to 2.12.x on
2024-05-25, which was reverted on 2024-09-26.

To try to confirm or deny this, I'm now trying a gtk-doc build with
libxml2 2.13.x from experimental:

    sbuild -dexperimental --add-depends='libxml2-utils (>= 2.13)' --add-depends='libxml2 (>= 2.13)' gtk-doc

The output of the one failing test, test-gobject-mkhtml, is:

I think this might be a behaviour change in libxml2, perhaps making it
more strict about the handling of missing resources with XInclude, or
perhaps changing the search path for those resources.

Because of the way gtk-doc is designed, this might trigger FTBFS in
packages that use gtk-doc for their documentation, not just a test
failure in gtk-doc itself. We'll need to take that into account (raising
the severity back to RC if not already fixed) when libxml2 gets upgraded
back to ≥ 2.12.x in future.

    smcv

--add-depends={python3-libxml2,libxml2,libxml2-utils}' (>= 2.13)'
but with that change, yes I can reproduce this test failure with libxml2's
version from experimental. So this is not immediately RC, but will become
RC again when the libxml2 maintainers are ready to retry the upgrade.
