croaks svnmerge en conflicto misteriosa

Question

ejecutar 1.6.x SVN en el servidor y el cliente. Me ramificado, trabajado durante varias semanas, downmerged un par de veces, y luego puse a volver upmerge. svnmerge.py, como conectado a continuación, divide las confirmaciones en dos conjuntos, y en el segundo set, se encuentra con una (falsa?) conflicto de árbol, y luego se hace un error de la subversión y la implosión (véase la parte inferior del registro).

Soy reacio a cometer este en dos partes, ya que el estado intermedio no era realmente funcional, por lo que ejecutar manualmente el primer conjunto de revisión y luego el segundo no es algo que quiero hacer.

Answer 1

La explicación ha surgido, y creo que esto podría ser interesante para alguien más.

Nunca, nunca, olvide a cometer una racha de svnmerge.py antes de hacer otra cosa. La combinación de una fusión con otras ediciones es una receta para un desastre, y el desastre es lo que se ve en la pregunta.
