From 482e1488a9b549cbf7466f4ee5396f93bb4588d6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Fri, 30 Jul 2021 18:18:14 +0200 Subject: t0001: fix broken not-quite getcwd(3) test in bed67874e2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With a54e938e5b (strbuf: support long paths w/o read rights in strbuf_getcwd() on FreeBSD, 2017-03-26) we had t0001 break on systems like OpenBSD and AIX whose getcwd(3) has standard (but not like glibc et al) behavior. This was partially fixed in bed67874e2 (t0001: skip test with restrictive permissions if getpwd(3) respects them, 2017-08-07). The problem with that fix is that while its analysis of the problem is correct, it doesn't actually call getcwd(3), instead it invokes "pwd -P". There is no guarantee that "pwd -P" is going to call getcwd(3), as opposed to e.g. being a shell built-in. On AIX under both bash and ksh this test breaks because "pwd -P" will happily display the current working directory, but getcwd(3) called by the "git init" we're testing here will fail to get it. I checked whether clobbering the $PWD environment variable would affect it, and it didn't. Presumably these shells keep track of their working directory internally. There's possible follow-up work here in teaching strbuf_getcwd() to get the working directory with whatever method "pwd" uses on these platforms. See [1] for a discussion of that, but let's take the easy way out here and just skip these tests by fixing the GETCWD_IGNORES_PERMS prerequisite to match the limitations of strbuf_getcwd(). 1. https://lore.kernel.org/git/b650bef5-d739-d98d-e9f1-fa292b6ce982@web.de/ Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'Makefile') diff --git a/Makefile b/Makefile index c3565fc0f8..8c000ba48b 100644 --- a/Makefile +++ b/Makefile @@ -711,6 +711,7 @@ TEST_BUILTINS_OBJS += test-example-decorate.o TEST_BUILTINS_OBJS += test-fast-rebase.o TEST_BUILTINS_OBJS += test-genrandom.o TEST_BUILTINS_OBJS += test-genzeros.o +TEST_BUILTINS_OBJS += test-getcwd.o TEST_BUILTINS_OBJS += test-hash-speed.o TEST_BUILTINS_OBJS += test-hash.o TEST_BUILTINS_OBJS += test-hashmap.o -- cgit v1.2.3
