From 3b0c3ab777d7d1fc2fbfaba9ec8ce4d845428d99 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 3 Aug 2016 19:00:32 -0400 Subject: trace: correct variable name in write() error message Our error message for write() always mentions GIT_TRACE, even though we may be writing for a different variable entirely. It's also not quite accurate to say "fd given by GIT_TRACE environment variable", as we may hit this error based on a filename the user put in the variable (we do complain and switch to stderr if the file cannot be opened, but it's still possible to hit a write() error on the descriptor later). So let's fix those things, and switch to our more usual "unable to do X: Y" format for the error.
