From: Jonathan Nieder Date: Tue, 15 Mar 2011 10:10:45 +0000 (-0500) Subject: tests: scrub environment of GIT_* variables X-Git-Tag: v1.7.5-rc0~40^2 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=95a1d12e9b9faddc02187ca28fdeb4fddd354c59;p=git.git tests: scrub environment of GIT_* variables Variables from the inherited environment that are meaningful to git can break tests in undesirable ways. For example, GIT_PAGER=more sh t5400-send-pack.sh -v -i hangs. So unset all environment variables in the GIT_ namespace in test-lib, with a few exceptions: - GIT_TRACE* are useful for tracking down bugs exhibited by a failing test; - GIT_DEBUG* are GIT_TRACE variables by another name, practically speaking. They should probably be tweaked to follow the GIT_TRACE_foo scheme and use trace_printf machinery some time. - GIT_USE_LOOKUP from v1.5.6-rc0~134^2~1 (sha1-lookup: more memory efficient search in sorted list of SHA-1, 2007-12-29) is about trying an alternate implementation strategy rather than changing semantics and it can be useful to compare performance with and without it set.
