Subject: [PATCH v2 09/18] Makefile: correct "GIT-PERL-{DEFINES,HEADER}" dependency graph
Date: Fri, 12 Nov 2021 22:48:53 +0100 [thread overview]
Message-ID: <patch-v2-09.18-c1336fc0a56-20211112T214150Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v2-00.18-00000000000-20211112T214150Z-avarab@gmail.com>
Fix several small issues with the dependency graph of the generated
"GIT-PERL-DEFINES" and "GIT-PERL-HEADER" files:
1. Don't have "GIT-PERL-HEADER" depend on the "Makefile". That was a
lazy way to over-declare the dependencies added in
f6a0ad4be71 (Makefile: generate Perl header from template file,
2018-04-10). Let's correct our dependency graph instead.
2. Don't have $(SCRIPT_PERL_GEN) (such as "git-send-email") depend on
GIT-BUILD-OPTIONS. Let's instead use GIT-PERL-DEFINES.
The reason for depending on "GIT-BUILD-OPTIONS" was to trigger a
re-build if NO_PERL=Y was defined. We can instead add that variable
to "PERL_DEFINES", and have "GIT-PERL-DEFINES" created and updated
if "NO_PERL=Y" is defined.
3. Due to #2 we'll need to have GIT-PERL-DEFINES be generated even
under NO_PERL, since that variable will be used by the
"unimplemented.sh" script.
4. Don't depend on $(gitexecdir), $(perllibdir) and $(localedir),
instead depend on the $(*_relative_SQ) versions of those.
The latter is what we'll actually use, while it's unlikely to
matter in practice (we'd just skip re-building these under
RUNTIME_PREFIX if the relative path was the same) it makes the code
easier to read.
That's because this brings us to a 1=1 mapping of these variables
and what's subsequently used in the "GIT-PERL-DEFINES",
"GIT-PERL-HEADER" and "perl/build/lib/%.pm" rules below.
5. We don't need the substitution of " " for ":" added in
07d90eadb50 (Makefile: add Perl runtime prefix support,
2018-04-10), let's drop it. This doesn't matter for the correctness
of these files, because unlike GIT-BUILD-OPTIONS nothing is
consuming them except the Makefile itself.
