Given the patchset sent by David seems to have been entirely contained
within what is now glance-store, I've moved this over and we can
determine if it still needs to be addressed there.

Title:
  Glance API layer doesn't catch some store exceptions leading to 500
  errors

Status in OpenStack Glance backend store-drivers library (glance_store):
  New

Bug description:
  The Glance API layer currently doesn't catch some exceptions raised by
  the underlying store layer, resulting in a "500 Internal Server
  Error".

  For e.g. when using the HTTP store, if the remote HTTP server is down,
  then an "image-download" operation will fail and the HTTP store will
  raise a BadStoreUri exception but the exception is not caught all the
  way to the top and results in the 500 error.

  Again, if the remote server is up but the specified image file is not
  found then the remote HTTP server will return a 404 error but the HTTP
  store converts all 4XX errors to a BadStoreUri exception (HTTP store
  bug?) which again is not caught.

  I think a) underlying stores should return appropriate error
  codes/exceptions so that the higher layers can take meaningful action
  or produce meaningful error messages and b) the API layer should catch
  all exceptions raised by the lower layers so that the user never gets
  to see a 500 error.
