[bitbake-devel] v4 or so [PATCH 0/2] variable/include tracking: revised

[Peter Seebach]

This is a revision of the variable/include tracking stuff. The first
patch adds include tracking, the second adds variable tracking on top of
it.

I am a little unsure about some of this. The big design issue I ran into
is that I often wanted to specify the name of the variable being passed,
but that if I passed a **loginfo containing a 'var' key, this clashed with
the positional 'var' parameter. So I changed the name to 'variable'. I also
made the inference code smarter; it can guess at variable name and value
in common cases, reducing typing. Similarly, there is no longer a need
for an explicit 'ignore'; rather, if the keyword dictionary is empty,
'ignore' is assumed. (It can still be specified explicitly if we find
an exception, such as a case where we often but not always want to record
an operation.)

There's a lot of things that could likely be improved with this; my
starting point was to make it produce basically the same results as the
previous patch set, then clean up the output quite a bit. So reporting
on overrides and _append/_prepend overrides is smarter now, output
format is cleaned up a bit, and so on.

Feedback welcome, as always. There may be some loose ends left over from
things I tried and then abandoned; I've tried to catch them all, but the
code's all blurred together for me at this point. Sending it out in part
because I suspect people might want to mess with this a bit, or give feedback.
