From 8c3ca351cb125c94870d7b8278a7efa1f1474d22 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Sat, 9 Apr 2016 13:42:31 -0400 Subject: config: lower-case first word of error strings This follows our usual style (both throughout git, and throughout the rest of this file). This covers the whole file, but note that I left the capitalization in the multi-sentence: error: malformed value... error: Must be one of ... because it helps make it clear that we are starting a new sentence in the second one.

But the gently form is designed to feed builtin/config.c, which passes our return code directly to its exit status, and thus uses positive error values for some cases. We check only negative values, meaning we would fail to die in some cases (e.g., a malformed key). This may or may not be triggerable in practice; we tend to use this non-gentle form only when setting internal variables, which would not have malformed keys.

However, our die message de-references "value", which may be NULL if the request was to unset a variable. Nobody using glibc noticed, because it simply prints "(null)", which is good enough for the test suite (and presumably very few people run across this in practice). But other libc implementations (like Solaris) may segfault. Let's not only fix that, but let's make the message more clear about what is going on in the "unset" case. Reported-by: "Tom G.
