From f7bae37f9ab2fdc567780d23495733c9af526e02 Mon Sep 17 00:00:00 2001 From: Shawn Pearce Date: Sun, 24 Sep 2006 22:50:15 -0400 Subject: [PATCH] Allow 'svn fetch' on '(no date)' revisions in Subversion. Added --ignore-nodate to allow 'git svn fetch' to import revisions from Subversion which have '(no date)' listed as the date of the revision. By default 'git svn fetch' will crash with an error when encountering such a revision. The user may restart the fetch operation by adding --ignore-nodate if they want to continue tracking that repository. I'm not entirely sure why a centralized version control system such as Subversion permits revisions to be created with absolutely no date/time associated with it but it apparently is possible as one of the Subversion repositories that I'm tracking with 'git svn' created such a revision on '(no date)' and by '(no user)'.
