From c740039921528198efa21f9cf6ccb849e74164c4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Fri, 21 Jun 2019 12:18:12 +0200 Subject: [PATCH] tests: make GIT_TEST_FAIL_PREREQS a boolean MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Change the GIT_TEST_FAIL_PREREQS variable from being "non-empty?" to being a more standard boolean variable. I recently added the variable in dfe1a17df9 ("tests: add a special setup where prerequisites fail", 2019-05-13), having to add another "non-empty?" special-case is what prompted me to write the "git env--helper" utility being used here. Converting this one is a bit tricky since we use it so early and frequently in the guts of the test code itself, so let's set a GIT_TEST_FAIL_PREREQS_INTERNAL which can be tested with the old "test -n" for the purposes of the shell code, and change the user-exposed and documented GIT_TEST_FAIL_PREREQS variable to a boolean.
