When working on (the still on-going) migration of the Gentoo java project repositories from SVN to Git I ran into bugs with svn2git 1.0.8 and my own svneverever 1.2.1. The bug with svn2git 1.0.8 was a regression that broke support for (non-ASCII) UTF-8 author names in identity maps. That's fixed in dev-vcs/svn2git-1.0.8-r1 in Gentoo. I sent the patch upstream and to the Debian package maintainer, too. For svneverever, a directory that re-appeared after deletion was reported to only live once, e.g. the output was

(2488; 9253)  /projects
(2490; 9253)      /java-config-2
(2490; 2586)          /trunk

if directory /projects/java-config-2/trunk/ got deleted at revision 2586, no matter if was re-created later. With 9253 revisions in total, the correct output (with svneverever 1.2.2) is:

(2488; 9253)  /projects
(2490; 9253)      /java-config-2
(2490; 9253)          /trunk
          ^

That's fixed in svneverever 1.2.2. If svneverever is of help to you, please support me on Flattr. Thanks!
