[Bug 1373454] [NEW] glance-api raises 500 error for invalid scheme while creating image

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

glance-api raises 500 error for invalid scheme while creating image using v1 api in get_store_or_400() method.
The reason, in this method exception.UnknownScheme() exception is caught and this UnknownScheme exception class is not present in glance/common/excepion.py module as it is moved under glance_store project.

Ideally it should caught UnknownScheme exception from glance_store's
exception  module.

Bug description:
  glance-api raises 500 error for invalid scheme while creating image using v1 api in get_store_or_400() method.
  The reason, in this method exception.UnknownScheme() exception is caught and this UnknownScheme exception class is not present in glance/common/excepion.py module as it is moved under glance_store project.

  Ideally it should caught UnknownScheme exception from glance_store's
  exception  module.
