Function Details

[hide private]

GetErrorClass(name)

source code

Return the class of an exception.

Given the class name, return the class itself.

Parameters:

name (str) - the exception name

Returns: class

the actual class, or None if not found

EncodeException(err)

source code

Encodes an exception into a format that MaybeRaise will recognise.

The passed err argument will be formatted as a tuple (exception name, arguments) that the MaybeRaise function will recognise.

Parameters:

err (GenericError child) - usually a child of GenericError (but any exception will be accepted)

Returns: tuple

tuple of (exception name, exception arguments)

GetEncodedError(result)

source code

If this looks like an encoded Ganeti exception, return it.

This function tries to parse the passed argument and if it looks like an encoding done by EncodeException, it will return the class object and arguments.

MaybeRaise(result)

source code

If this looks like an encoded Ganeti exception, raise it.

This function tries to parse the passed argument and if it looks like an encoding done by EncodeException, it will re-raise it.
