Version: 3.11-3build1
Ubuntu release: 20.04
The python3-ply binary package should provide these virtual packages: python3-ply-lex-3.10, python3-ply-yacc-3.10, but it cannot provide them after a build in a fresh focal docker container.
This is because the provided virtual package names are generated by the 'debian/virtual-packages.py' script, which uses a shebang with '/usr/bin/python'. By default there is no 'python' binary on ubuntu focal.
One solution could be adding the 'python-is-python2' package as a build dependency. I have used this temporarily.
Or the shebang could be more specific: '/usr/bin/python2' or '/usr/bin/env python2'.
Or the script could be ported to python3 with a proper specific shebang.
It would also be useful to raise a build error, when the script fails. |
[Impact]
* If we (or a user) has to re-build ply, it misbuilds, silently.
[Test Plan]
Rebuild from source.
apt show python3-ply | grep Provides
Good:
Provides: python3-ply-lex-3.10, python3-ply-yacc-3.10
Bad:
Empty output.
[Where problems could occur]
* Pretty minimal risk, no library code changes.
Just getting things to build correctly, again.
[Other Info]
* The -4 upload included a port of the virtual package script to Python 3. Not backporting that, because it's a larger change.
