From: Ævar Arnfjörð Bjarmason Date: Fri, 6 Aug 2010 22:09:09 +0000 (+0000) Subject: tests: A SANITY test prereq for testing if we're root X-Git-Tag: v1.7.3-rc0~2^2~46 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=c91cfd19160be63e97f28dce8c9af421b61c9938;p=git.git tests: A SANITY test prereq for testing if we're root Some tests depend on not being able to write to files after chmod -w. This doesn't work when running the tests as root. Change test-lib.sh to test if this works, and if so it sets a new SANITY test prerequisite. The tests that use this previously failed when run under root. There was already a test for this in t3600-rm.sh, added by Junio C Hamano in 2283645 in 2006. That check now uses the new SANITY prerequisite. Some of this was resurrected from the "Tests in Cygwin" thread in May 2009: http://thread.gmane.org/gmane.comp.version-control.git/116729/focus=118385 Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- diff --git a/t/README b/t/README index dc0793937..28effb443 100644 --- a/t/README +++ b/t/README @@ -523,6 +523,11 @@ use these, and "test_set_prereq" for how to define your own.
