E ValueError: bad marshal data (unknown type code)
/usr/lib/python3/dist-packages/textual/style.py:396: ValueError
This was my NMU, so I'm sorry for not spotting the problem in advance; I
thought the rich changes were small enough to avoid compatibility issues
in textual and missed the fact that they switched from marshal to pickle
for style meta information. However, I don't think the compatibility
breakage could really have been avoided anyway: the change that caused
this was part of upstream changes to support Python 3.14, and when I
experimented locally I also couldn't find a way to get marshal.dumps to
do the right thing on Python 3.14 so I can absolutely see why they
switched to pickle instead.
The corresponding upstream fix to textual is in a commit unhelpfully
labelled just "optimization"
(https://github.com/Textualize/textual/pull/6169); as far as I can see
upstream failed to label either side of this as affecting compatibility
between rich and textual. I think the only sensible way forward is to
cherry-pick the relevant part of the textual change as well, add a
Depends to textual for the new rich, and add a Breaks on old textual
versions to rich.
https://salsa.debian.org/morph/textual/-/merge_requests/1 has the
necessary changes to textual, and I've attached a debdiff here too. The
change to rich would then just be adding "Breaks: python3-textual (<<
2.1.2-1.1~)".
Thanks,
