tests: make GIT_TEST_GETTEXT_POISON a boolean
Change the GIT_TEST_GETTEXT_POISON variable from being "non-empty?" to being a more standard boolean variable. Since it needed to be checked in both C code and shellscript (via test -n) it was one of the remaining shellscript-like variables. Now that we have "env--helper" we can change that. There's a couple of tricky edge cases that arise because we're using git_env_bool() early, and the config-reading "env--helper". If GIT_TEST_GETTEXT_POISON is set to an invalid value die_bad_number() will die, but to do so it would usually call gettext(). Let's detect the special case of GIT_TEST_GETTEXT_POISON and always emit that message in the C locale, lest we infinitely loop. As seen in the updated tests in t0017-env-helper.sh there's also a caveat related to "env--helper" needing to read the config for trace2 purposes. Since the C_LOCALE_OUTPUT prerequisite is lazy and relies on "env--helper" we could get invalid results if we failed to read the config (e.g. because we'd loop on includes) when combined with e.g. "test_i18ngrep" wanting to check with "env--helper" if GIT_TEST_GETTEXT_POISON was true or not. I'm crossing my fingers and hoping that a test similar to the one I removed in the earlier "config tests: simplify include cycle test" change in this series won't happen again, and testing for this explicitly in "env--helper"'s own tests. This change breaks existing uses of e.g. GIT_TEST_GETTEXT_POISON=YesPlease, which we've documented in po/README and other places. As noted in [1] we might want to consider also accepting "YesPlease" in "env--helper" as a special-case. But as the lack of uproar over 6cdccfce1e ("i18n: make GETTEXT_POISON a runtime option", 2018-11-08) demonstrates the audience for this option is a really narrow set of git developers, who shouldn't have much trouble modifying their test scripts, so I think it's better to deal with that minor headache now and make all the relevant GIT_TEST_* variables boolean in the same way than carry the "YesPlease" special-case forward. 1. https://public-inbox.org/git/xmqqtvckm3h8.fsf@gitster-ct.c.googlers.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
