We plan to continue on our plan to disable automagic Python bytecompilation so I'd like to summarize what you can expect.
If you don't know what I am talking about, please read this change [0] and its second phase [1].
Currently, we have 130 packages with `%global
_python_bytecompile_extra 1` in their specfiles [2] but
suprisingly only 42 of them (listed below) actually ship any .pyc
files outside the standard location
"/usr/lib(64)?/python[0-9]\.[0-9]+". That might be caused by
either of the following:
A) there is nothing to byte-compile -- the statement is a leftover
to be removed
B) The automagic bytecompilation uses /usr/bin/python by default
(for historical reasons) but /usr/bin/python is not present in the
buildroot by default.
Those 42 packages should switch to explicit `%py_byte_compile` [3], for example:
%py_byte_compile %{python3}
%{buildroot}%{_datadir}/mypackage/bar
Remember that this has something to do only for importable Python modules and only outside the standard location.
I'll prepare a Fedora change proposal for this but I wanted to inform maintainers in advance.
The new RPM macros will raise an error if
_python_bytecompile_extra will be defined to 1. Package
maintainers should switch to %py_byte_compile or just remove it
from the specfile if it's not needed.
I'll definitely help with this transition as much as I can.
Have a nice day.
