From cb2cada6da9d71604fd09efbff47cddbea453e1e Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Sat, 28 Apr 2007 20:29:23 -0400 Subject: [PATCH] Catch empty pathnames in trees during fsck Released versions of fast-import have been able to create a tree that contains files or subtrees that contain no name. Unfortunately these trees aren't valid, but people may have actually tried to create them due to bugs in import-tars.perl or their own fast-import frontend. We now look for this unusual condition and warn the user if at least one of their tree objects contains the problem. Signed-off-by: Shawn O.
