For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.10/fedora-rawhide-x86_64/01794473-python-pyqtgraph/

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

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.

Comment 1 Scott Talbert 2020-11-27 03:52:29 UTC
I updated to a new upstream release of pyqtgraph hoping that it might fix this issue - however the new upstream grew some new dependencies on PyQt5 and h5py, and it cannot be built at the moment using the 3.10 COPR.  Can you please ping me again when those packages are available in the COPR?

Error: 
 Problem 1: cannot install the best candidate for the job
  - nothing provides libQt5Quick.so.5(Qt_5.15.2_PRIVATE_API)(64bit) needed by python3-qt5-5.15.0-3.fc34.x86_64
 Problem 2: cannot install both python3-numpy-1:1.19.4-1.fc34.x86_64 and python3-numpy-1:1.19.4-2.fc34.x86_64
  - package python3-h5py-3.1.0-1.fc34.x86_64 requires python3.9dist(numpy) >= 1.19.3, but none of the providers can be installed
  - cannot install the best candidate for the job
  - conflicting requests
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Comment 2 Tomáš Hrnčiar 2020-11-27 07:21:34 UTC
Thank you for looking into this. In the meantime, PyQt5 started to build https://copr.fedorainfracloud.org/coprs/g/python/python3.10/build/1796361/. 
h5py depends on python-pytest-mpi (rhbz#1900524).

Comment 3 Scott Talbert 2021-02-06 18:05:24 UTC
This is now blocked on scipy:
Error: 
 Problem: package python3-scipy-1.6.0-3.fc34.x86_64 requires python(abi) = 3.9, but none of the providers can be installed
  - package python3-devel-3.10.0~a5-1.fc34.x86_64 conflicts with python3 < 3.10.0~a5-1.fc34 provided by python3-3.9.1-5.fc34.i686
  - package python3-devel-3.10.0~a5-1.fc34.x86_64 conflicts with python3 < 3.10.0~a5-1.fc34 provided by python3-3.9.1-5.fc34.x86_64
  - cannot install the best candidate for the job
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

I don't see an open bug for scipy, which seems to be segfaulting during build, although it's not clear to me exactly what's segfaulting.  The python interpreter?

Comment 4 Miro Hrončok 2021-02-06 18:09:32 UTC
We have *just now* updated to 3.10.0a5. The segfault is likely caused by some of the imported extension module built with a4. We'll need to bootstrap it over, give it a couple of days.

Comment 5 Miro Hrončok 2021-02-07 10:26:33 UTC
Scipy built fine.

Comment 6 Scott Talbert 2021-02-07 14:32:17 UTC
Looks like sphinx-build is now segfaulting for pyqtgraph:

+ make -C doc html
make: Entering directory '/builddir/build/BUILD/pyqtgraph-0.11.1/doc'
sphinx-build -b html -d build/doctrees   source build/html
Running Sphinx v3.4.3
make: *** [Makefile:40: html] Segmentation fault (core dumped)
make: Leaving directory '/builddir/build/BUILD/pyqtgraph-0.11.1/doc'
error: Bad exit status from /var/tmp/rpm-tmp.lTsVsP (%build)

It appears that python-sphinx has already been rebuilt with 3.10.0a5 though?

Comment 7 Miro Hrončok 2021-02-07 16:55:53 UTC
python-sphinx is noarch, this is usually a problem with extension module (arched package) that's imported in the process.

If you work locally, make sure to scrub the mock's dnf cache. E.g. mock -r fedora-rawhide-python310 --scrub=dnf-cache

Comment 8 Miro Hrončok 2021-02-07 16:59:27 UTC
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/h5py/ hasn't been built with a5 yet. maybe that's it.

I'll try to do more rounds of everyhting.

Comment 9 Miro Hrončok 2021-02-07 17:15:04 UTC
And that allowed the build to go past the sphinx failure.

I've seen this before in different places. Round the float.

Comment 11 Miro Hrončok 2021-02-07 18:01:34 UTC
I believe the cause is https://bugs.python.org/issue37999

Comment 12 Ben Cotton 2021-02-09 15:28:38 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.

Comment 13 Scott Talbert 2021-03-26 23:07:22 UTC
Should finally be fixed.  :-)
