From 2edffef2337eae691a454a072e0f9b9538725317 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 27 Sep 2016 16:59:50 -0400 Subject: tree-walk: be more specific about corrupt tree errors When the tree-walker runs into an error, it just calls die(), and the message is always "corrupt tree file". However, we are actually covering several cases here; let's give the user a hint about what happened. Let's also avoid using the word "corrupt", which makes it seem like the data bit-rotted on disk. Our sha1 check would already have found that. These errors are ones of data that is malformed in the first place.
