From 1ff750b128e041b3477ef9ee2768990e606d1c33 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Fri, 21 Jun 2019 12:18:09 +0200 Subject: tests: make GIT_TEST_GETTEXT_POISON a boolean MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 Signed-off-by: Junio C Hamano --- gettext.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'gettext.c') diff --git a/gettext.c b/gettext.c index d4021d690c..5c71f4c8b9 100644 --- a/gettext.c +++ b/gettext.c @@ -50,10 +50,8 @@ const char *get_preferred_languages(void) int use_gettext_poison(void) { static int poison_requested = -1; - if (poison_requested == -1) { - const char *v = getenv("GIT_TEST_GETTEXT_POISON"); - poison_requested = v && strlen(v) ? 1 : 0; - } + if (poison_requested == -1) + poison_requested = git_env_bool("GIT_TEST_GETTEXT_POISON", 0); return poison_requested; } -- cgit v1.2.3
