Summary: libphutil has some basic environmental sanity checks that we should use when initializing scripts in Phabricator. Principally this: https://secure.phabricator.com/diffusion/PHU/browse/master/scripts/__init_script__.php;db643ee9f5f524e7$26 Without this, the default ini may set CLI errors to go to some logfile, which means exceptions aren't shown on stderr. See https://github.com/facebook/phabricator/issues/98/ Test Plan: - Ran "php -derror_log=/dev/null -f ./bin/phd debug adslkfnasdfnalks" prior to change; got confusing lack of output. - Ran "phd -derror_log=/dev/null -f ./bin/phd debug asdkflnaslfdnala" after change; got exception on stderr.
