Let's move these around so that the variables and defines needed by given targets immediately precede them. This is not needed for any subsequent changes to work, but makes the code consistent with how GIT-PERL-DEFINES is structured.

Now every time HEAD changes in a development copy we don't need to re-build the scripts and script libraries. This has not been needed since 2b9391bc675 (Makefile: do not replace @@GIT_VERSION@@ in shell scripts, 2012-06-20). On my setup this changes the re-making of 44 targets in a development copy where moved HEAD to 27. The $(GIT_VERSION) was seemingly left here by mistake or omission. We didn't need it since 2b9391bc675, but in the later e4dd89ab984 (Makefile: update scripts when build-time parameters change, 2012-06-20) it was added to SCRIPT_DEFINES. The two were part of the same series of patches, and given the summary in [1] and [2] it looks like this was probably a case of some earlier version of a later patch being combined with an updated earlier patch. 1. https://lore.kernel.org/git/20120619232231.GA6328@sigill.intra.peff.net/ 2. https://lore.kernel.org/git/20120619232453.GB6496@sigill.intra.peff.net/ Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Makefile b/Makefile index f52402b24d..fdce392929 100644 --- a/Makefile +++ b/Makefile @@ -2252,7 +2252,7 @@ command-list.h: $(wildcard Documentation/git*.txt) hook-list.h: generate-hooklist.sh Documentation/githooks.txt $(QUIET_GEN)$(SHELL_PATH) ./generate-hooklist.sh >$@ -SCRIPT_DEFINES = $(SHELL_PATH_SQ):$(DIFF_SQ):$(GIT_VERSION):\ +SCRIPT_DEFINES = $(SHELL_PATH_SQ):$(DIFF_SQ):\ $(localedir_SQ):$(NO_CURL):$(USE_GETTEXT_SCHEME):$(SANE_TOOL_PATH_SQ):\ $(gitwebdir_SQ):$(PERL_PATH_SQ):$(SANE_TEXT_GREP):$(PAGER_ENV):\ $(perllibdir_SQ) -- cgit v1.2.3 From c7c969289792f9fbc4cfd9850bb228b4c9cd967e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Thu, 21 Oct 2021 21:57:57 +0200 Subject: Makefile: remove $(NO_CURL) from $(SCRIPT_DEFINES) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Stop including $(NO_CURL) in $(SCRIPT_DEFINES).

The reason for the check was to support users who had a newer version of git and an older version of gitweb, it was then subsequently adjusted for changes in the script in f0e588dffc1 (git-instaweb: fix mod_perl detection for apache2, 2009-08-08). It's a fair bet that nobody's running a git from 2021 and gitweb from pre-2007 anymore, so we can unconditionally assume that this will be supported by gitweb.cgi. This allows a subsequent commit to remove the sane_grep() wrapper, this change is split up from that since this is the only case where the "grep" invocation could be removed entirely.

The two reasons for why it existed don't apply anymore: 1. It was added due to GNU grep supporting GREP_OPTIONS. See e1622bfcbad (Protect scripted Porcelains from GREP_OPTIONS insanity, 2009-11-23). Newer versions of GNU grep ignore that, but even on older versions its existence won't matter, none of these sane_grep() uses care about grep's output, they're merely using it to check if a string exists in a file or stream. We also don't care about the "LC_ALL=C" that "sane_grep" was using, these greps for fixed or ASCII strings will behave the same under any locale. 2. The SANE_TEXT_GREP added in 71b401032b9 (sane_grep: pass "-a" if grep accepts it, 2016-03-08) isn't needed either, none of these grep uses deal with binary data.
