Re: [PATCH] tests: handle NO_PYTHON setting

Shouldn't this section be moved down below the sourcing of ../GIT-BUILD-OPTIONS

Oops, good catch. I stupidly tested with "make NO_PYTHON=1 test" instead
of actually checking that GIT-BUILD-OPTIONS was propagating it
correctly.

ps. There's something eerily familiar about this patch.

Hmmm. Yes, I didn't search before writing it, but you probably mean:

  http://article.gmane.org/gmane.comp.version-control.git/127172

But that is missing the NO-PYTHON bit in GIT-BUILD-OPTIONS (did you
forget it there, or was it part of some other patch that also didn't get
applied?).

Also, I am tempted to move the GIT-BUILD-OPTIONS invocation _up_. It
is about reading config and should probably come before we start doing
_anything_.

So maybe this instead:

Subject: [PATCH] tests: handle NO_PYTHON setting

Without this, test-lib checks that the git_remote_helpers
directory has been built. However, if we are building
without python, we will not have done anything at all in
that directory, and test-lib's sanity check will fail.

We bump the inclusion of GIT-BUILD-OPTIONS further up in
test-lib; it contains configuration, and as such should be
read before we do any checks (and in this particular case,
we need its value to do our check properly).

I moved the BUILD-OPTIONS thing to just above the beginning of the
"have you built anything" checks, but after all of the function
definitions. But perhaps it should simply go at the very top of the
script. After all, in the case of "make NO_PYTHON=1 test", those
variables will already be defined at the very beginning of the script.
