# ZeekControl exceptions.
|
|
#
|
|
# These are the exceptions that are expected to be raised under predictable
|
|
# circumstances (such as bad user input, or an invalid configuration). When
|
|
# these are raised, a text message explaining the problem should be provided.
|
|
# Therefore, these should be caught to avoid seeing a stack trace (which
|
|
# provides no new information in these cases). However, standard Python
|
|
# exceptions are not expected to occur, so if one is raised a stack trace
|
|
# can provide valuable information on the source of the problem.
