Add a 'dependency-debug' and a 'DEPENDENCY_DEBUG=1' option for 'info-boards-supported' to save some variables used when resolving dependencies. Print some some 'sorted' variables to simplify comparing the actual value when the parsing order changed. This should help tracking changes introduced when refactoring the dependency parsing.

# Debug targets to evaluate dependency migrations

|
# The goal is to get the value of variables used for dependency resolution
|
|
# and the impact of refactoring
|
|
|
|
# Files output can be generated through the normal resolution with executing
|
|
# 'dependency-debug' for each board
|
|
#
|
|
# BOARD=board_name make dependency-debug
|
|
#
|
|
# And the 'quick' version that is used by murdock with `info-boards-supported`.
|
|
# This one currently uses only a subset of the files/values required for
|
|
# dependency resolution.
|
|
#
|
|
# DEPENDENCY_DEBUG=1 make info-boards-supported
|
|
#
|
|
#
|
|
# To compare in an aggregated file, you can run in an application directory:
|
|
#
|
|
# for board in $(make info-boards); do DEPENDENCY_DEBUG_OUTPUT_DIR=bin/info BOARD=${board} make dependency-debug; done; cat bin/info/* > bin/deps_info
|
|
# DEPENDENCY_DEBUG=1 DEPENDENCY_DEBUG_OUTPUT_DIR=bin/info-global make info-boards-supported; cat bin/info-global/* > bin/deps_info-boards-supported
|
|
# # And compare both files
|
|
# diff -u bin/deps_info bin/deps_info-boards-supported
|
|
#
|
|
# And when comparing two revisions, include the revision in the file names
|
|
|
|
.PHONY: dependency-debug
|
|
# Only generate the dependencies when the board is not disabled
|
|
# This will allow comparing with the output of `info-boards-supported` more easily
