From df58a8274d6865020682a6739bc59b87a9761991 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 1 Sep 2008 23:20:26 -0700 Subject: [PATCH] diff --quiet: make it synonym to --exit-code >/dev/null The point of --quiet was to return the status as early as possible without doing any extra processing. Well behaved scripts, when they expect to run many diff operations inside, are supposed to run "update-index --refresh" upfront; we do not want them to pay the price of iterating over the index and comparing the contents to fix the stat dirtiness, and we avoided most of the processing in diffcore_std() when --quiet is in effect. But scripts that adhere to the good practice won't have to pay any more price than the necessary lstat(2) that will report stat cleanliness, as long as only -q is given without any fancier diff options. More importantly, users who do ask for "--quiet -M --filter=D" (in order to notice only the deletion, not paths that disappeared only because they have been renamed away) deserve to get the result they asked for, even it means they have to pay the extra price; the alternative is to get a cheap early return that gives a result they did not ask for, which is much worse.
