[bitbake-devel] [PATCH v2 1/3] event/ast: Add RecipeTaskPreProcess event before task finalisation

[Patrick Ohly]

From: Richard Purdie <richard.purdie at linuxfoundation.org>

There are various pieces of code which need to run after the tasks are
finalised but before bitbake locks in on the task dependencies. This
adds such an event so dependency changes in anonymous python can
be accounted for and acted upon by these specific event handlers.
