Kirkstone : vs _ bugs

Kirkstone : vs _ bugs

[Joakim Tjernlund]

Porting to Kirkstone I stumbled over this:
  PREFERRED_VERSION:xyz = 1.2.3
does not work in Kirkstone but works in Dunfell, need to replace : with _


FILES_${PN} is silently ignored in Kirkstone, replacing _ with : makes build happy again.

It is unclear to me when to use : vs. _ in Yocto for Kirkstone, is there a list?

See openembedded-core/scripts/contrib/convert-overrides.py script which
does most of the heavy lifting and there is a plenty of examples how to
update the layers.

This is side effect of the bitbake change which replaces all ':' with "_"
as a way to allow using new syntax with older bitbake, but unfortunately it
replaces it everywhere (even where it shouldn't be used at all in first
place), that's why it works in dunfell with older bitbake while kirkstone
correctly refuses it.

Problem is that it is not clear the the avage user when/where to use : vs _ and only some cases of wrong use makes bitbake throw an error.
It can take a long time to figure out where the error is.
Why is PREFERRED_VERSION:xyz wrong ?

Examples of already migrated layers don't help?

> Why is PREFERRED_VERSION:xyz wrong ?

Because xyz is not an override.
