For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.10/fedora-rawhide-x86_64/02086151-weasyprint/

For all our attempts to build weasyprint with Python 3.10, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/weasyprint/

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.10:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/

Let us know here if you have any questions.

Python 3.10 will be included in Fedora 35. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.10.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.

buil.log with segfaulting tests skipped

I've added --ignore weasyprint/tests/test_layout/test_shrink_to_fit.py to be able to at least see the regular failures.

It seems that many of the failures have to do with "width". E.g.:

>       assert kern.width == 1.5 * 16
E       assert 18.0 == (1.5 * 16)
E        +  where 18.0 = <InlineBox span>.width

But there are other failures as well:

>       column1, column2, section1, section2, column3, column4 = div.children
E       ValueError: not enough values to unpack (expected 6, got 4)

Full log attached.

Comment 2 Felix Schwarz 2021-03-23 23:09:48 UTC
There was an incompatibility with pango 1.48.3. I cherry-picked an upstream patch to fix that.

rawhide build succeeds now: https://koji.fedoraproject.org/koji/taskinfo?taskID=64462748

Comment 3 Miro Hrončok 2021-06-04 20:15:39 UTC
This is a mass-posted update. Sorry if it is not 100% accurate to this bugzilla.


The Python 3.10 rebuild is in progress in a Koji side tag. If you manage to fix the problem, please commit the fix in the rawhide branch, but don't build the package in regular rawhide.

You can either build the package in the side tag, with:

    $ fedpkg build --target=f35-python

Or you can the build and we will eventually build it for you.

Note that the rebuild is still in progress, so not all (build) dependencies of this package might be available right away.

Thanks.

If you have general questions about the rebuild, please use this mailing list thread: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/G47SGOYIQLRDTWGOSLSWERZSSHXDEDH5/

Comment 4 Miro Hrončok 2021-06-07 23:00:01 UTC
The f35-python side tag has been merged to Rawhide. From now on, build as you would normally build.

Comment 5 Miro Hrončok 2021-06-14 10:37:22 UTC
This package was successfully rebuilt with Python 3.10.

If you need this bugzilla open for tracking purposes, sorry for the automatic closing: feel free to reopen it.
