Re: [Rpm-maint] [rpm-software-management/rpm] Should python(abi) be provided by the interpreter or something else? (#395)

2018-02-15 Thread Jeff Johnson 
The python(abi) requirement was originally invented to associate a *.py script 
in a package with an interpreter package. Most of the Requires: are 
automatically generated from *.py files (which ultimately determines how the 
Provides: should be added).

Detailed dependency semantics involving embedded interpreters and libraries and 
interpreter sub-packaging are largely ad hoc and de facto, so there really 
isn't any right or wrong, only what "works".

[Rpm-maint] [rpm-software-management/rpm] Should python(abi) be provided by the interpreter or something else? (#395)

2018-02-15 Thread Miro Hrončok 
https://github.com/rpm-software-management/rpm/blob/b60a086213b5f0ffd68b445e51d205eb1ac64396/scripts/pythondistdeps.py#L129-L134

I believe this adds `python(abi) == 2.7` for Fedora's `python2-libs`, because 
it owns `/usr/lib64/python2.7/lib-dynload/Python-2.7.14-py2.7.egg-info`. 
However, it was always the case that only the package that owns 
`/usr/bin/python2.7` provides `python(abi) == 2.7`:

https://github.com/rpm-software-management/rpm/blob/b60a086213b5f0ffd68b445e51d205eb1ac64396/scripts/pythondeps.sh#L11-L17

This in fact makes  `python2-libs` satisfy the requirement on `python(abi) == 
2.7` without bringing in `python2` (and `/usr/bin/python2.7`). This was 
[reported as a problem](https://bugzilla.redhat.com/show_bug.cgi?id=1412432).

Now I can fix the problem in several ways:

 * require `python2` from `python2-libs` (adds a dependency that's not always 
needed, but mostly it is)
 * filter `python(abi) == 2.7` by some exclude macro (meh...)
 * move the `Python-2.7.14-py2.7.egg-info` into `python2` package
 * remove the entire section of `pythondistdeps.py`

Before I proceed, I'd like to know why is this code there and what should 
`python(abi)` actually mean – is it the interpreter, or not? Thanks for 
clarifying this.

Guesses are worthless, particularly when you haven't the time to identify your 
problem.
