Hi,
I've updated python-envisage in Salsa[1] to the latest upstream version
and bumped its failing predepends to their according latest upstream and
fixed all bugs in those. For envisage I'm stumbling upon a Python3.10
related bug I'd like to ask for help:
...

I spent some time looking into this. The problem is that upstream includes binary eggs (which are Python version specific) as part of its test suite. The problem here is that there are no eggs included for Python 3.10. Upstream is aware of this[1] but unfortunately, that patch can't be applied because it is a binary patch. They have also later[2] removed the binary eggs completely, but that patch can't be applied either because it involves files that are not in the PyPI distribution. The best solution might be do what Fedora did[3], but for that we'd probably have to switch to using a GitHub tarball instead of the PyPI tarball because the PyPI tarball is missing files.
