When perlSupport = false, we will set NO_PERL=1, and build Git without
Perl support. This is a build option that Git supports. However, Git's
test suite still requires a Perl to be available to run the tests, and
we did not provide one. The tests respect PERL_PATH, and if it is not
set, they default to /usr/bin/perl.
Before this commit, if we set "perlSupport = false", then no Perl would
be available to the package, and so the tests would default to
/usr/bin/perl. When building without a sandbox, that could still work,
even though there is no "perl" on the path, because the tests defaulted
to an absolute path.
You can reproduce this issue as follows:
nix-build -E 'let pkgs = (import ./default.nix) {}; in pkgs.git.override { perlSupport = false; }'
I just ran into this when trying to build pkgs.git from an old version
of Nixpkgs that I was able to build just fine in the past, and today it
would not build any more, complaining when running the tests:
make -C t/ all
make[1]: Entering directory '/build/git-2.18.0/t'
rm -f -r 'test-results'
/nix/store/czx8vkrb9jdgjyz8qfksh10vrnqa723l-bash-4.4-p23/bin/bash: /usr/bin/perl: No such file or directory
In the past the sandbox was not enabled by default, so then it worked
for me. But now that it is enabled, my host's (not NixOS) /usr/bin/perl
is no longer accessible, and the build fails.
The solution is to explicitly set PERL_PATH when running the tests. This
*almost* works, except that there appears to be a bug in the test for
"git request-pull". That command is a Bash script that calls Perl at
some point, so it requires Perl, and therefore it cannot be supported
when NO_PERL=1. But that particular test does not check whether Git was
compiled with Perl support (other tests do include that check), and that
makes the test fail:
t5150-request-pull.sh ..............................
not ok 4 - pull request after push
not ok 5 - request asks HEAD to be pulled
not ok 6 - pull request format
not ok 7 - request-pull ignores OPTIONS_KEEPDASHDASH poison
not ok 9 - pull request with mismatched object
not ok 10 - pull request with stale object
Dubious, test returned 1 (wstat 256, 0x100)
Failed 6/10 subtests
This output makes sense if you look at t5150-request-pull.sh. Test 1 and
2 are setup steps. Test 3 does call request-pull, but it expects the
command to fail, and it cannot distinguish between the command exiting
with a nonzero exit code, or failing to start it at all. So test 3
passes for the wrong reasons. Test 4 through 10 all call request-pull,
so they fail.
The quick workaround here is to disable the test. I will look into
upstreaming a patch that makes the test skip itself when Perl is
disabled.
Use autoreconfHook instead of preConfigure autogen.sh. This avoids
getting the bad version of the gnu-config script and makes the newish
iOS triples work.

libtool is not really needed and it interferes with
updateAutotoolsGnuConfigScriptsHook. So remove it when
cross-compiling, but leave it in native to preserve hashes.
The skia patch no longer applies, and is no longer necessary.
The current version of chromium doesn't build with gcc. This has been
fixed upstream[1] and could be backported, but switching aarch64 to
clang/llvm and making the build the same on all platforms is simpler.
