Public bug reported: with 0.14+20091101-1, the test.py works well. $ python test.py Xlib.protocol.request.QueryExtension _NET_SUPPORTED is supported False _NET_WM_NAME is not supported True
but with 0.14+20091101-1ubuntu1, it will throw exceptions $ # python2 $ python test.py <class 'Xlib.protocol.request.QueryExtension'> _NET_SUPPORTED is supported Traceback (most recent call last): File "test.py", line 16, in <module> print (root.get_full_property(atom, 0) == None) File "/usr/lib/python2.7/dist-packages/Xlib/xobject/drawable.py", line 457, in get_full_property prop.bytes_after // 4) + 1 TypeError: unsupported operand type(s) for +: 'GetProperty' and 'int' _NET_WM_NAME is not supported Traceback (most recent call last): File "test.py", line 27, in <module> print (root.get_full_property(atom, 0) == None) File "/usr/lib/python2.7/dist-packages/Xlib/xobject/drawable.py", line 452, in get_full_property prop = self.get_property(property, type, 0, sizehint) File "/usr/lib/python2.7/dist-packages/Xlib/xobject/drawable.py", line 441, in get_property long_length = length) File "/usr/lib/python2.7/dist-packages/Xlib/protocol/rq.py", line 1477, in __init__ self.reply() File "/usr/lib/python2.7/dist-packages/Xlib/protocol/rq.py", line 1489, in reply self._display.send_and_recv(request = self._serial) File "/usr/lib/python2.7/dist-packages/Xlib/protocol/display.py", line 556, in send_and_recv gotreq = self.parse_response(request) File "/usr/lib/python2.7/dist-packages/Xlib/protocol/display.py", line 643, in parse_response gotreq = self.parse_request_response(request) or gotreq File "/usr/lib/python2.7/dist-packages/Xlib/protocol/display.py", line 729, in parse_request_response req._parse_response(self.data_recv[:self.request_length]) File "/usr/lib/python2.7/dist-packages/Xlib/protocol/rq.py", line 1501, in _parse_response self._data, d = self._reply.parse_binary(data, self._display, rawdict = 1) File "<string>", line 8, in parse_binary File "/usr/lib/python2.7/dist-packages/Xlib/protocol/rq.py", line 647, in parse_binary_value if type(ret[1]) is bytes: TypeError: 'NoneType' object has no attribute '__getitem__' $ # python3 $ python3 test.py <class 'Xlib.protocol.request.QueryExtension'> _NET_SUPPORTED is supported Traceback (most recent call last): File "test.py", line 16, in <module> print (root.get_full_property(atom, 0) == None) File "/usr/lib/python3/dist-packages/Xlib/xobject/drawable.py", line 457, in get_full_property prop.bytes_after // 4) + 1 TypeError: unsupported operand type(s) for +: 'GetProperty' and 'int' _NET_WM_NAME is not supported Traceback (most recent call last): File "test.py", line 27, in <module> print (root.get_full_property(atom, 0) == None) File "/usr/lib/python3/dist-packages/Xlib/xobject/drawable.py", line 452, in get_full_property prop = self.get_property(property, type, 0, sizehint) File "/usr/lib/python3/dist-packages/Xlib/xobject/drawable.py", line 441, in get_property long_length = length) File "/usr/lib/python3/dist-packages/Xlib/protocol/rq.py", line 1477, in __init__ self.reply() File "/usr/lib/python3/dist-packages/Xlib/protocol/rq.py", line 1489, in reply self._display.send_and_recv(request = self._serial) File "/usr/lib/python3/dist-packages/Xlib/protocol/display.py", line 556, in send_and_recv gotreq = self.parse_response(request) File "/usr/lib/python3/dist-packages/Xlib/protocol/display.py", line 643, in parse_response gotreq = self.parse_request_response(request) or gotreq File "/usr/lib/python3/dist-packages/Xlib/protocol/display.py", line 729, in parse_request_response req._parse_response(self.data_recv[:self.request_length]) File "/usr/lib/python3/dist-packages/Xlib/protocol/rq.py", line 1501, in _parse_response self._data, d = self._reply.parse_binary(data, self._display, rawdict = 1) File "<string>", line 8, in parse_binary File "/usr/lib/python3/dist-packages/Xlib/protocol/rq.py", line 647, in parse_binary_value if type(ret[1]) is bytes: TypeError: 'NoneType' object is not subscriptable ** Affects: python-xlib (Ubuntu) Importance: Undecided Status: New ** Attachment added: "test.py" https://bugs.launchpad.net/bugs/1231453/+attachment/3842293/+files/test.py -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1231453 Title: get_full_property() throws exceptions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python-xlib/+bug/1231453/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
