I had posted some rudimentary changes in ownet for python a week or so ago. After fighting why iButtonLink MS-TH humidity readings were causing "value errors," I poked a bit more at the ownet python code.
It appears, from my quick and dirty run, that owserver is sending back data in a format that python ownet is failing on. Specifically the payload_len is -1. Also, the correct data seems to follow in another data packet. My approach in this quick fix was to just ignore the -1 payload len packet (message) and interpret the next one as the proper data. I'm unsure if this will work in all cases or just this one. Comments are welcome, I'm still pouring over the C source trying to glean the complete protocol spec. The second is the previous change to ownet's init method regarding proper interpretation of the port as an integer and a rewritten init () method that uses the parameters or the initialized values. The third diff is for the swig/perl makefile to work on OSX. Seems configure is not treating it properly. Have not looked more than to make a manual change, removing the unsupported "-shared" options. Here are my diff's from the most recent CVS diff -r owfs-cvs/module/ownet/python/ownet/connection.py owfs/module/ ownet/python/ownet/connection.py 138c138 < if payload_len: --- > if payload_len >= 0: 141a142,143 > elif payload_len < 0: > pass diff -r owfs-cvs/module/ownet/python/ownet/__init__.py owfs/module/ ownet/python/ownet/__init__.py 108c108 < _port = pair[1] --- > _port = int(pair[1]) 136a137,138 > If server or port are specified they will override the initialized > values from ownet.init() 143,149d144 < elif not server or not port: < global _server < global _port < if not _server or not _port: < raise exNotInitialized < else: < self._connection = Connection(server, port) 151c146,157 < self._connection = Connection(server, port) --- > global _server > global _port > if not server: > server = _server > > if not port: > port = _port > > if not server or not port: > raise exNotInitialized > > self._connection = Connection(server, port) diff -r owfs-cvs/module/swig/perl5/Makefile.PL.in owfs/module/swig/ perl5/Makefile.PL.in 15c15 < 'LDDLFLAGS' => q[-shared -Wl,-L../../owlib/src/c/.libs - Wl,[EMAIL PROTECTED]@/lib], --- > 'LDDLFLAGS' => q[-bundle -flat_namespace -undefined suppress -Wl,-L../../owlib/src/c/.libs -Wl], Stephen ---------------------------------------------------------------- Stephen Houser http://usm.maine.edu/~houser Division of Information and Technology [EMAIL PROTECTED] University of Southern Maine (207)780-4588 P.O.
