Hi Martin,
I'm looking into de-duplicating reprotest's embedded copies of autopkgtest code.
In #833407 you said "Using the Python API (adt_testbed.py) is a lot easier and
more robust than talking to the backend servers directly", but adt_testbed.py
is currently not available as a public Python module. How do you expect users
to use it?
Might I suggest you make "/usr/share/autopkgtest/lib" available as a python
package? autopkgtest is a fine name for it. I understand you might have some
reservations about exposing some "internal" files like this, but the Pythonic
way is to prefix those with an underscore (as the stdlib does) and/or document
this fact clearly.
By contrast, putting a whole python package into a private path and then
hacking sys.path to be able to find this, is not really the appropriate
"Pythonic" way to do this. I can certainly sympathise, if you have
philosophical problems with Python's approach to module-hiding, but I think
this approach is not the best way to fight that fight. Rather, one would try to
make a PEP that constructs something clean, that everyone can use.
I've also attached the additional changes that Ceridwen made to the code, since
she imported it just before 4.0 was released. I have yet to study it in detail,
but feel free to comment in the meantime - if you see any major
incompatibilities that would be hard to fix in reprotest, it would be good for
me to know quickly and early.
