# 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.
