These tests demonstrate that it is not easy to exclude only one top-level
directory from being extracted, using the example of lang/gcc*, which has
a top-level directory contrib/ that contains shell programs with
non-portable code, but the same archive also contains libjava/contrib, and
that should still be extracted.
The severity now depends only on the setting of SUBST_NOOP_OK. Right now
this means that some former warnings will be reported as info only, but
that will change after switching the default of SUBST_NOOP_OK after
2020Q1. Then they will all be reported as warnings, followed by the final
error saying that the pattern has no effect.
This change makes it easier to detect inconsistencies and outdated
definitions, for example by setting the global SUBST_NOOP_OK=no and
redefining WARNING_MSG to actuall fail.
In the old test code, the input and output data for each test case were
in different files. This was too far apart to relate them. In addition,
all test cases were merged into a single big test, which made it hard to
tell the topics apart.
The default value of SUBST_MESSAGE is based on SUBST_FILES, and that
variable may use the :sh modifier to list files from WRKSRC, which may
not exist at load time.
Before, the first assertion failure quit immediately. This prevented
getting a complete picture of the situation that failed. Now the
assertions continue the test and fail at the very end.
In the case of pkglocaledir, the SUBST_FILES are generated by a shell
command. That command assumes that the WRKDIR already exists. Therefore
SUBST_FILES must be evaluated as late as possible.
See mk/configure/replace-localedir.mk; an example package that fails is
devel/gettext-tools.
