From f4beed60d5ef3fdbd31ac5bd3162182fdf2bf0d3 Mon Sep 17 00:00:00 2001 From: Felipe Contreras Date: Tue, 17 May 2016 16:40:23 -0500 Subject: fast-import: do not truncate exported marks file Certain lines of the marks file might be corrupted (or the objects missing due to a garbage collection), but that's no reason to truncate the file and essentially destroy the rest of it. Ideally missing objects should not cause a crash, we could just skip them, but that's another patch.
