Description Miro Hrončok 2020-01-16 23:16:37 UTC
python-gpxpy fails to build with Python 3.9.0a2.

ERROR: test_extension_without_namespaces (__main__.GPXTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/builddir/build/BUILD/gpxpy-1.3.5/test.py", line 3073, in test_extension_without_namespaces
    self.assertEqual("eee", gpx.waypoints[0].extensions[1].getchildren()[0].text.strip())
AttributeError: 'xml.etree.ElementTree.Element' object has no attribute 'getchildren'

======================================================================
ERROR: test_with_ns_namespace (__main__.GPXTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/builddir/build/BUILD/gpxpy-1.3.5/test.py", line 3107, in test_with_ns_namespace

See https://docs.python.org/3.9/whatsnew/3.9.html#removed

"Methods getchildren() and getiterator() in the ElementTree module have been removed. They were deprecated in Python 3.2. Use functions list() and iter() instead. The xml.etree.cElementTree module has been removed." 


For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.9/fedora-rawhide-x86_64/01149016-python-gpxpy/

For all our attempts to build python-gpxpy with Python 3.9, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/python-gpxpy/

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 3.9:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/

Let us know here if you have any questions.

Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9.
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.

Upstream report : https://github.com/tkrajina/gpxpy/issues/191

Comment 2 Elliott Sales de Andrade 2020-01-28 19:59:18 UTC
This should be fixed in python-gpxpy-1.4.0-1.fc32.

Comment 3 Elliott Sales de Andrade 2020-02-08 21:31:08 UTC
I see there's a working build now: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/build/1219706/
