If a parent-relative file external is defined, using the ../ URL-shorthand
notation in the externals definition, and a working working copy containing this
external is switched to a different branch (which also contains the same
externals definition), the working copy will fail to update itself after the switch.
Error messages differ depending on the repository access method.
This is the error message for ra_local:
svn: warning: apr_err=SVN_ERR_FS_NOT_FOUND
svn: warning: W160013: Working copy path 'gamma-ext' does not exist in repository
subversion/svn/update-cmd.c:175: (apr_err=SVN_ERR_CL_ERROR_PROCESSING_EXTERNALS)
svn: E205011: Failure occurred processing one or more externals definitions
svn: warning: apr_err=SVN_ERR_FS_NOT_FOUND

subversion/svn/update-cmd.c:175: (apr_err=SVN_ERR_CL_ERROR_PROCESSING_EXTERNALS)
svn: E205011: Failure occurred processing one or more externals definitions
For ra_serf, the message looks like:
