Create a note for every imported commit containing svn metadata
To provide metadata from svn dumps for further processing, e.g. branch detection, attach a note to each imported commit that stores additional information. The notes are currently hard-coded in refs/notes/svn/revs. Currently the following lines from the svn dump are directly accumulated in the note. This can be refined as needed. - "Revision-number" - "Node-path" - "Node-kind" - "Node-action" - "Node-copyfrom-path" - "Node-copyfrom-rev" Signed-off-by: Florian Achleitner <florian.achleitner.2.6.31@gmail.com> Acked-by: David Michael Barr <b@rr-dav.id.au> Signed-off-by: Junio C Hamano <gitster@pobox.com>
