             Summary: svnmucc fails to delete directories that contain just deletes
                 Key: SVN-4665
                 URL: https://issues.apache.org/jira/browse/SVN-4665
             Project: Subversion
          Issue Type: Bug
          Components: svnmucc
    Affects Versions: 1.9.x
            Reporter: Bert Huijben
             Fix For: 1.9.0


{noformat:nopanel=true}
'svnmucc' fails to process action sequences where a delete action follows
a modify/propset or another delete on the same path.  This behavior is a
regression in Subversion 1.9.0 RC1 compared to 1.8.13:

  echo content > file
  svnmucc --root-url URL --message "r1" put file /file
  svnmucc --root-url URL --message "r2" put file /file rm /file
  # svnmucc: E200009: Can't delete node at 'file'

  echo content > file
  svnmucc --root-url URL --message "r1" put file /file
  svnmucc --root-url URL --message "r2" propset prop val /file rm /file
  # svnmucc: E200009: Can't delete node at 'file'

  echo content > file
  svnmucc --root-url URL --message "r1" put file /file
  svnmucc --root-url URL --message "r2" rm /file rm /file
  # svnmucc: E160013: Can't delete node at 'file' as it does not exist
  # (nothing is committed to the repository, and /file still exists in HEAD)

With Subversion 1.8.13, these command sequences end without errors and
remove /file.  The corresponding design decision is documented in
^/subversion/branches/1.8.x/subversion/svnmucc/svnmucc.c:460:

  /* We won't fuss about multiple operations on the same path in the
     following cases:

       - the prior operation was, in fact, a no-op (open)
       - the prior operation was a propset placeholder
       - the prior operation was a deletion ... */
