From 22396175267b7bcef97a02036831152539429bec Mon Sep 17 00:00:00 2001 From: Jeff King Date: Sun, 31 Jan 2016 22:18:24 -0500 Subject: [PATCH] checkout-index: disallow "--no-stage" option We do not really expect people to use "--no-stage", but if they do, git currently segfaults. We could instead have it undo the effects of a previous "--stage", but this gets tricky around the "to_tempfile" flag. We cannot simply reset it to 0, because we don't know if it was set by a previous "--stage=all" or an explicit "--temp" option. We could solve this by setting a flag and resolving to_tempfile later, but it's not worth the effort. Nobody actually wants to use "--no-stage"; we are just trying to fix a potential segfault here. While we're in the area, let's improve the user-facing messages for this option. The error string should be translatable, and we should give some hint in the "-h" output about what can go in the argument field.
