[bitbake-devel] [PATCH] bitbake: command: add getOverrideData command

[Chris Laplante]

While working on a script using tinfoil, I needed a way to access the
overridedata for a given variable. Unfortunately, I found that
data_smart does not have remotedata proxying for it.

By adding the getOverrideData command, I am able to use a method like
this to access override data (either for a particular var, or all data):

def get_override_data(d, var=None):
    if "_remote_data" in d:
        connector = d["_remote_data"]  # type: bb.tinfoil.TinfoilDataStoreConnector
        return connector.getOverrideData(var)

    if var:
        return d.overridedata[var]
    return d.overridedata
