[OE-core] EXPORT_FUNCTIONS - change in behaviour proposal

[Richard Purdie]

After Enrico's reported problem, I've been poking around the
EXPORT_FUNCTIONS code. Currently OE-Core metadata generates list A
below. In particular, this leads to code like:

 do_configure calls gnomebase_do_configure
 gnomebase_do_configure calls autotools_do_configure

which has a level of indirection. The gnomebase class never references
do_configure. I can appreciate adding in a default mapping of:

 do_configure calls autotools_do_configure

since it allows a user to call into autotools_do_configure from a custom
do_configure but I can't see the value of the intermediary
gnomebase_do_configure. Does anyone know of a use for it?

I have a suspicion that if it ever did do anything useful, it stopped
being useful long ago.

I'm therefore strongly tempted to remove the intermediaries from the
code. This would result in list B below which is a more direct set of
mappings.

Any thoughts/comments from anyone?

Cheers,

Richard
