LayerIndex/Checker

This is a little project to increase the quality of the LayerIndex entries.

We do not have a name yet, so we just call it 'Checker' for now.

It uses existing tools and the guidelines documented e.g. in the BSP guides and in the existing tests/tooling.

Currently it does 3 things:

a) grep LAYERSERIES_COMPAT <layer>/conf/layer.conf

b) grep LAYERDEPENDS <layer>/conf/layer.conf

[ run bitbake-layer layerindex-fetch $layer ]

c) run layer check script: yocto-check-layer (from OE-core repo)

An example run is available on this page for 'dunfell' LayerIndex/Checker/dunfell

Next steps:

• need help with:
  • Update layerindex to add field noting the layer passed the 'checker' (or however we will name it)
  • Expose api call to upload this for branch/layer/package combination
  • option: add field showing if the checker did run/run last
  • option: add field noting the error if it did not pass
  • There seems to be either a bug in bitbake-layers layerindex-fetch or in the layerindex causing some dunfell projects to not complete the fetch

• • • This seems to be https://bugzilla.yoctoproject.org/show_bug.cgi?id=13954

• will do myself
  • update script to work against api
  • will host runner for layers.openembedded.org (weekly/stable branches ... master does not make too much sense atm).
  • enhance script to pick machines for BSP layers
