What I really need is information about introspection or the ability to query an existing yocto distro to return data about features included and more to the point, to understand EXACTLY where recipes or classes are overridden or appended. You can only do so much with recursive grep and find scripts. Based on what I've seen so far, it seems that capability is lacking in yocto.
In essence I have what is like a one way hash ABCDEFG-->X and I have X but cannot fully figure out the whole input that generated it.
An example would be an overridden task method like
do_something
I need a quick way to determine the highest priority level that task was overridden or appended in for a given recipe.
a command like "bitbake -describe -c do_something my-recipe"
bitbake -e my-recipe ?
Maybe grep for the variable of interest?
and it should also be possible to query this kind of information for variables and not just methods or tasks.
Do these tools exist or am I looking at parsing megabytes of verbose build data and tracing output to find what I'm looking for?
and no, I didn't create the distro...I'm an end user customer who was given an undocumented distro with quazi-proprietary BSP layers in it that not only describe our specific product purchased, but the vendor's others products as well, which complicates matters.
Thoughts?
When adding layers, only way to be sure is to actually review the layers and their bbappends. I tend to BBMASK everything out which I haven't checked at least on BSP layer side. Open source layers from yocto community are better.
