# -----------------------------------------------------------------------------
# This set of libraries are used to verify linker namespaces.
# -----------------------------------------------------------------------------

# -----------------------------------------------------------------------------
# Test cases
# 1. Check that private libraries loaded in different namespaces are
#    different. Check that dlsym does not confuse them.
# 2. Check that public libraries loaded in different namespaces are shared
#    between them.
# 3. Check that namespace sticks on dlopen
# 4. Check that having access to shared library (libnstest_public.so)
#    does not expose symbols from dependent library (libnstest_public_internal.so)
#
# Dependency tree (visibility)
# libnstest_root.so (this should be local to the namespace)
# +-> libnstest_public.so
#     +-> libnstest_public_internal.so
# +-> libnstest_private.so
#
# libnstest_dlopened.so (library in private namespace dlopened from libnstest_root.so)
