  "message": "tests: scrub environment of GIT_* variables\n\nVariables from the inherited environment that are meaningful to git\ncan break tests in undesirable ways.  For example,\n\n\tGIT_PAGER\u003dmore sh t5400-send-pack.sh -v -i\n\nhangs.  So unset all environment variables in the GIT_ namespace in\ntest-lib, with a few exceptions:\n\n- GIT_TRACE* are useful for tracking down bugs exhibited by a failing\n  test;\n\n- GIT_DEBUG* are GIT_TRACE variables by another name, practically\n  speaking.  They should probably be tweaked to follow the\n  GIT_TRACE_foo scheme and use trace_printf machinery some time.\n\n- GIT_USE_LOOKUP from v1.5.6-rc0~134^2~1 (sha1-lookup: more memory\n  efficient search in sorted list of SHA-1, 2007-12-29) is about\n  trying an alternate implementation strategy rather than changing\n  semantics and it can be useful to compare performance with and\n  without it set.\n\nSigned-off-by: Jonathan Nieder \u003cjrnieder@gmail.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
