[Toaster] 7414 example for layer 'meta', is it really a layer?

[Damian, Alexandru]

Ufff, I've just seen this email now.

We do have a matching algorithm in - buildinfohelper.py.

The idea is that, if we control the build, we already know where the
sources are checked out (bc.be.sourcedir), and what is the layer directory
name (bc.getGitCloneDirectory(brl.giturl, brl.commit), so we can match the
layer.

On the latest submission, for _recipes_, we already logging only the short
path (i.e. relative to the layer) !

Hope this helps,
Alex


 707             # Heuristics: we match the path to where the layers have
been checked out
 708             for brl in sorted(BuildRequest.objects.get(pk =
br_id).brlayer_set.all(), reverse = True, key = _slkey_managed):
 709                 localdirname =
os.path.join(bc.getGitCloneDirectory(brl.giturl, brl.commit), brl.dirpath)
 710                 # we get a relative path, unless running in HEAD mode
where the path is absolute
 711                 if not localdirname.startswith("/"):
 712                     localdirname = os.path.join(bc.be.sourcedir,
localdirname)
 713                 if path.startswith(localdirname):
 714                     #logger.warn("-- managed: matched path %s with
layer %s " % (path, localdirname))
 715                     # we matched the BRLayer, but we need the
layer_version that generated this br
 716                     for lvo in self.orm_wrapper.layer_version_objects:
 717                         if brl.name == lvo.layer.name:
 718                             return lvo
