# These tests check that the order of the flags in .pc files are correct
# after resolving the package list. There are two things that are
# critical in the current algorithm: the ordering of packages on the
# command line, the ordering of packages based on Requires and the place
# in the pkg-config path the .pc file was found, with packages earlier
# in the path getting higher priority. There is one other factor that
# makes the output currently work correctly that's only implicitly
# tested here: stripping of all duplicates from the output string.
#
# There are 3 sets of packages here:
#
# 1. A typical setup where highest level package is earliest in the path
# and has a straight dependency chain. 3-1 -> 2-1 -> 1-1 with 3-1 in the
# first part of the user supplied path, 2-1 in the second part, and 1-1
# found from the system path.
#
# 2. A similar setup to 1 except that now both 3-2 and 2-2 depend on
# 1-2. This has a subtle effect on the algorithm when combined with the
# order of the command line arguments. It only currently works because
# duplicates get strip out in (hopefully) the correct order, so 1-2's
# flags come out in the appropriate spot even though it was in the
# package list twice.
#
# 3. Reverse the order of requirements so that the system level package
# (1-3) depends on something in the user's path (2-3), which depends on
# something earlier in the user's path (3-3). This is pretty unusual
# since the user is typically overriding something higher in the stack
# rather than lower, but it does illustrate the path ordering vs.
# dependency ordering.
