Zope 3 exception views

This packages provides Zope 3 browser views for some generic exceptions.

System Errors

System Errors are errors representing a system failure. At the application level, they are errors that are uncaught by the application and that a developer hasn’t provided a custom error view for.

Zope provides a default system error view that prints an obnoxius terse message and that sets the response status.

There is a simple view registered in ftesting.zcml which raises Exception():

>>> print(http(r"""
... GET /error.html HTTP/1.1
... """))
HTTP/1.0 500 Internal Server Error
  A system error occurred.

Another way of getting a system error is the occurrence of a system error, such as ComponentLookupError. I have registered a simple view in ftesting.zcml, too, that will raise a component lookup error. So if we call componentlookuperror.html, we should get the error message:

>>> print(http(r"""
... GET /componentlookuperror.html HTTP/1.1
... """))
HTTP/1.0 500 Internal Server Error
  A system error occurred.
