From 7814fbe3f1e7cea1a675408df7b5dd1f5be731cc Mon Sep 17 00:00:00 2001 From: Johannes Sixt Date: Wed, 14 Dec 2016 20:37:38 +0100 Subject: normalize_path_copy(): fix pushing to //server/share/dir on Windows normalize_path_copy() is not prepared to keep the double-slash of a //server/share/dir kind of path, but treats it like a regular POSIX style path and transforms it to /server/share/dir. The bug manifests when 'git push //server/share/dir master' is run, because tmp_objdir_add_as_alternate() uses the path in normalized form when it registers the quarantine object database via link_alt_odb_entries(). Needless to say that the directory cannot be accessed using the wrongly normalized path. Fix it by skipping all of the root part, not just a potential drive prefix. offset_1st_component takes care of this, see the implementation in compat/mingw.c::mingw_offset_1st_component().
