[Debian-pan-maintainers] Bug#1029775: pyhst2: FTBFS with setuptools 66: Invalid version: '2020ca'

[Didier 'OdyX' Raboud]

Control: tags -1 confirmed +patch

Hello there,

while at St-Cergue's BSP, I took a look at this issue, so here are my 
findings.

* I can confirm it fails to build from source in a main+contrib+non-free 
cowbuilder.

* This FTBFS is the consequence of a new requirement from setuptools; see this 
issue to get it better: https://github.com/pypa/setuptools/issues/2497 .
setuptools now imposes PEP-440-style versioning, that is, the version has to 
match this format:

	[N!]N(.N)*[{a|b|rc}N][.postN][.devN]

But pyHST2 uses the version number in some paths (such as /usr/lib/python3/
dist-packages/PyHST2_2020c(...) ), so it can't simply be patched to use 
"2020.3" (c ~= 3 ?). I can't login to upstream's issues tracker at
https://gitlab.esrf.fr/mirone/pyhst2 but it's clearly something that needs to 
be fixed by a new upstream release.

The attached patch is basically a `sed 's/2020c/2021/g' -i` (also check 
aumento_versione="a" which can work, but should also be amended)  on concerned 
files. It allows to finish building, but the paths have become 
/usr/lib/python3/dist-packages/PyHST2_2021(...), which is clearly not 
upstream's intent.

I'll check if it's possible to only patch the version and not all files.

See you in a bit.

Cheers,

OdyX
