As a side note, It always seemed to me that the bf_getcharbuffer´s semantics were poorly defined. At least in the 2.3 documentation. Has that, and the need for it, changed recently?

While investigating this I discovered that buffer objects, for their tp_as_buffer->bf_getcharbuffer, return the result by calling the wrapped object bf_getreadbuffer or bf_getwritebuffer. This is wrong since it is essentially redirecting the expected call to the wrong tp_as_buffer slot for the wrapped object. Plus it doesn't have Py_TPFLAGS_HAVE_GETCHARBUFFER defined. I see two options here. One is to remove the bf_getcharbuffer slot from the buffer object. The other option is to fix it so that it only returns bf_getcharbuffer and doesn't redirect improperly (this also brings up the issue if Py_TPFLAGS_HAVE_GETCHARBUFFER should then also be defined for buffer objects). Since I don't use buffer objects I don't know if it is better to fix this or just rip it out. -Brett _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/kristjan%40ccpgames.com _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
