From 91c38a21089c4b30d35f392386c752a017ac6db0 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 8 Jan 2010 07:39:11 -0800 Subject: [PATCH] ident.c: check explicit identity for name and email separately MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit bb1ae3f (commit: Show committer if automatic, 2008-05-04) added a logic to check both name and email were given explicitly by the end user, but it assumed that fmt_ident() is never called before git_default_user_config() is called, which was fragile. The former calls setup_ident() and fills the "default" name and email, so the check in the config parser would have mistakenly said both are given even if only user.name was provided. Make the logic more robust by keeping track of name and email separately.
