Re: [Boost-users] BGL python bindings: copy.copy(g) adds spurious properties

Hi,

When a graph is copied via copy.copy(g), extra vertex and edge property maps are added.

import boost.graph as bgl g = bgl.Graph() prop = g.add_vertex_property('prop') from copy import copy g_copy = copy(g) print g.vertex_properties.keys() print g_copy.vertex_properties.keys()

Output:

g's vertex properties: ['prop'] g_copy's vertex properties: ['object', 'prop']

This property named 'object' contains the same values as the 'prop' property.

Is this a bug in the pickling support?

Definitely a bug, which was in the "unpickling" routines. I believe I've fixed this in Subversion. - Doug
