Ticket #937 (defect)

Order of filters in CherryPy 2

• on_start_resource

processHeaders()

• before_request_body

processBody()

• before_main

main(), which included controller lookup

• before_finalize

finalize()

• on_end_resource

Order of hooks in CherryPy 3:

process_headers()
get_resource(), which looks up the controller

• on_start_resource
• before_request_body

process_body()

• before_handler

handler()

• before_finalize

finalize()

• on_end_resource

IMO, it would be good to get rid of the 'before_request_body' hookpoint altogether, and move the builtin tools to use 'on_start_resource' instead.

We could ease migration by having the next version of CP move hooks from before_request_body to on_start_resource (with a DeprecationWarning), and adding 100 to their priority so they all run in the same order but after all the ones explicitly set at on_start_resource.
