From d6991ceedc6a6fbcc2184f8328eb1b4c88b55267 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 14 Nov 2012 16:34:13 -0800 Subject: [PATCH] ident: keep separate "explicit" flags for author and committer We keep track of whether the user ident was given to us explicitly, or if we guessed at it from system parameters like username and hostname. However, we kept only a single variable. This covers the common cases (because the author and committer will usually come from the same explicit source), but can miss two cases: 1. GIT_COMMITTER_* is set explicitly, but we fallback for GIT_AUTHOR. We claim the ident is explicit, even though the author is not. 2. GIT_AUTHOR_* is set and we ask for author ident, but not committer ident. We will claim the ident is implicit, even though it is explicit. This patch uses two variables instead of one, updates both when we set the "fallback" values, and updates them individually when we read from the environment. Rather than keep user_ident_sufficiently_given as a compatibility wrapper, we update the only two callers to check the committer_ident, which matches their intent and what was happening already.
