Description (last modified by )
The _boundary attribute has been deprecated since Sage 6.3 in #15494. This ticket totally removes it fro the graph class.
The branch fixes a small problem that went probably unnoticed in #15494: the function Graph.genus was using this attribute (and so has been raising warnings for one year) but there was no other way to give a list of vertices to the function. Consequently, this branch turns one of its boolean arguments into a list, so that this function can be used properly, i.e. without global variables.

Please do not add such a message on the ticket without explaining why. The developper's manual says that the deprecation should hold for at least a year, and this deprecation is from more than one year.

 Milestone changed from sage6.5 to sagepending
I think the "one year" rule should be interpreted since a stable Sage release, not just since the opening of the ticket. The idea is to give users a one year warning that whatever they are using is deprecated.
It's very unreasonable to expect users to read all trac tickets for deprecations.

Really Jeroen, I do not think that you are achieving anything besides being unpleasant. Coming on somebody else's ticket to discuss whether the date to take into account for deprecation is the day it was merged or the stable release that followed, really....
You take into account the 'first stable release' as the first date on which the deprecation appears, and you add a message here saying that 'no beta release' should be made that contains this branch. Stable on one hand, beta on the other, and all for nothing.
Anyway. Not even worth fighting for, it is just unpleasant and pointless.

Replying to ncohen:
Coming on somebody else's ticket to discuss whether the date to take into account for deprecation is the day it was merged or the stable release that followed, really....
For this ticket, it was merged in the git repo 20150606, which is only half a year ago.

Hello,
I did small modifications, but I'm not good for pushing commits and so all is in a new branch. Sorry for that.
I did only the following modifications:
 in both files
graph.py
anddigraph.py
, remove in the description of the class parameters ``boundary``  a list of boundary vertices, if empty, digraph is considered as a 'graph without boundary'
 and remove
boundary=None
indef __init__(self, data=None, pos=None, loops=None, format=None, boundary=None, weighted=None, implementation='c_graph', data_structure="sparse", vertex_labels=True, name=None, multiedges=None, convert_empty_dict_labels_to_None=None, sparse=True, immutable=False):
 In file
generic_graph.py
, remove wordboundary
from the method description:meth:`~GenericGraph.clear`  Empty the graph of vertices and edges and removes name, boundary, associated objects, and position information.
 and in
def clear(self): """ Empties the graph of vertices and edges and removes name, boundary, associated objects, and position information.
If you agree, you can set the ticket to positive review.
David.
