From 381766efcdddb4c8706408a90c515470a6aa43a7 Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Tue, 15 Nov 2016 21:29:54 -0400 Subject: Avoid backtraces on expected failures when built with ghc 8; only use backtraces for unexpected errors. ghc 8 added backtraces on uncaught errors. This is great, but git-annex was using error in many places for a error message targeted at the user, in some known problem case. A backtrace only confuses such a message, so omit it. Notably, commands like git annex drop that failed due to eg, numcopies, used to use error, so had a backtrace.
