New Revision: 1683718
URL: http://svn.apache.org/r1683718
Log:
On the 'move-tracking-2' branch: Start implementing migration of history
from non-move-tracking repository revisions. Just a framework, so far.
* subversion/include/private/svn_editor3e.h
(svn_branch_get_migration_editor): New.
* subversion/libsvn_delta/migrate.c
New.
* subversion/svnmover/svnmover.c
(action_code_t,
action_defn,
execute): Define the 'migrate' action.
(migrate_replay_baton_t,
migrate_replay_rev_started,
migrate_replay_rev_finished,
do_migrate): New.
