Subject: [PATCH v2 0/6] Makefile/perl: correctly re-generate build/* + speed up under NO_GETTEXT=Y
Date: Mon, 10 May 2021 12:50:16 +0200	[thread overview]
Message-ID: <cover-0.6-00000000000-20210510T104937Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-0.4-00000000000-20210505T121857Z-avarab@gmail.com>

The summary, from v1:

    These patches are relatively trivial fixes for bugs noticed when I was
    working on recent send-email patches. We don't re-build perl/build/*
    assets when variables that affect them are changed, and needlessly use
    our non-mock gettext Perl i18n framework under NO_GETTEXT=Y if the
    system happens to have Locale::Messages installed.

Changes since v1:

The only change to the end-state is the trivial change-on-top of:

    -PERL_DEFINES :=
    +PERL_DEFINES =

I.e. the PERL_DEFINES is now also refactored away from a
simply-expanded variable. The re-arrangement and split-up of patches
in this v2 just makes for a more incremental way to get there, per the
discussion on v1.

    -    Makefile: don't re-define PERL_DEFINES
    +    Makefile: split up the deceleration of PERL_DEFINES
     
    -    Since 07d90eadb50 (Makefile: add Perl runtime prefix support,
    -    2018-04-10) we have been declaring PERL_DEFINES right after assigning
    -    to it, with the effect that the first PERL_DEFINES was ignored.
    +    Split the declaration of PERL_DEFINES across multiple line, making
    +    this easier to read.
     
    -    That bug didn't matter in practice since the first line had all the
    -    same variables as the second, so we'd correctly re-generate
    -    everything. It just made for confusing reading.
    -
    -    Let's remove that first assignment, and while we're at it split these
    -    across lines to make them more maintainable.
    +    In 07d90eadb50 (Makefile: add Perl runtime prefix support, 2018-04-10)
    +    when PERL_DEFINES was added only the RUNTIME_PREFIX was put on its own
    +    line the rest weren't formatted like that for consistency. Let's do
    +    that to make this consistent with most of the rest of this Makefile.
