[bitbake-devel] [PATCH] runqueue: Allow the hash validate function to have an idea of build completion

[Richard Purdie]

There is an oversight in the current hash validation API in that the
function can't know how many setscene tasks already completed. Rather
than trying to add additional parameters to the function, causing
incompatibilities, store the value in the datastore.

This is useful to allow build status reporting to the user for
figures on sstate reusage and build completion.
