always define _ALWAYS_DEP, _BUILD_DEP, _RUN_DEP and test for emptiness
instead of definedness, so that the code is still optimized away when
dependency lists are defined, but empty.
Use eval to simplify passing those to submakes.
Note that the preferred separator is ',', not ':'.
(Because ':' can't be used unambiguously in *_DEPENDS, whereas ',' can)
NetBSD did this a while ago, this is a natural idea. It just took me
some time to figure out how to do that in a MULTI_PACKAGE context,
while maintaining compatibility with existing stuff.
* pull every dependency under the same rule, using specialized fragments.
* re-check after the dependency is expanded, unless earlyexit is true.
* explicitly recognize /nonexistent as a specific way to have always
triggered dependencies, use it to handle DEPENDS in a uniform way.
* parse dependencies fully. Note that we know have a pkg variable that will
be used.
Thanks to naddy@ for useful tweaks.
This is probably not quite perfect yet, stuff may break. Other stuff that
remain to be done:
- handle library dependencies better, so that lib.10 will match only
lib.10.x and not lib.100.
- handle default FLAVORS correctly. This involves not
passing FLAVOR='', but rearranging ${MAKE} ${_DEPEND_THRU} to remove
FLAVOR from the environment and from MAKEFLAGS (yucky).
The cleaner fix would be to create the package to stdout under SUDO
and redirect it, but that junk (pkg_create) is actively fighting that.
God, I've got to rewrite it and retire that crap.
it's so seldom used now).
Remove a few targets that are not really needed (mirror-distfiles, use
mirror-maker instead).
More changes to fake to come, once they've been properly tested.
this is stupid (BATCH is only there to skip IS_INTERACTIVE ports).
Make PATCH_CHECK_ONLY a Yes/No switch.
Let it be a slightly better no-op, e.g., skip creating the cookies
in checkpatch operation.
