Hervé, All,

On 2021-06-21 16:11 +0200, Herve Codina spake thusly:
> Fixing _sysconfigdata*.{py,pyc} was previously done by python package
> infrastructure. Some packages use python stuff without using python
> package infrastructure.
> These packages perform overwrites and need the specific python fixup
> to fix them.
> 
> In order to be sure to fix all of these packages, the python fixup
> is moved to the generic package infrastructure and applied to all
> packages.
> This follows the same principle as for the .la libtool files fixup.

So, earlier in the series, you introduced _PER_PACKAGE_TWEAK_HOOKS (or
whatever the name it will eventually bear), stating that infras could
set it, but here  you are not taking the chance to demonstrate this,
and instead you are inserting the python fixups in an ad-hoc way.

Which also illustrates that the libtool fixups should be converted to
the _PER_PACKAGE_TWEAK_HOOKS, probably...

Otherwise, this is a good change.

Yann E. MORIN.
