Hi folks, I'm working to improve python bindings. Already done: * Session rewritten in C (removed a lot of unsafe transfers from python to C and vice versa. * Added exceptions for errors handling * Reviewed/refactored/rewritten half of code
Unfortunately, I changed the interface of Session::get*(), Session::set() functions. get*() takes as argument python list of Varbinds and returns _new_ list of Varbinds with filled values and types. set() returns None. All raise exceptions if error has occurred. (Next, also get*() will take callback and return None for asynchronous call and a simple Varbind may be passed to functions) It's ok? I remind that in the current code get*() takes VarList of Varbinds as argument, changes the VarList and returns tuple ".val"s of Varbinds. VarList - this is wrapper of python list. http://git.sgu.ru/?p=net-snmp.git;a=blob;f=net-snmp/python/netsnmp/client.py;h=c7f1ac7e06e00112f19c1286a4876d28885e6477;hb=upstream#l66 My changes makes VarList unnecessary, functions's behavior more transparent and clear. So, I have a few questions about the next work. Session members. I think, the Session object contains a lot of not required members, a change that is no affected (such as, SecName, SecSecEngineId, etc.). Also struct netsnmp_session contains part of these members in readable form. Maybe leave only the main members, that can be obtained from netsnmp_session (such as, .Use*, .DestHost, ports, etc.)? To simplify the part of C code, Varbind in C needed (also for removing a lot of transfers Python <-> C). May I merge tag and iid to simple ".name". The snmplib allows me to work with the simple "name" in the bindings. Setting output format. In the current code output format is set at the library-wide. http://git.sgu.ru/?p=net-snmp.git;a=blob;f=net-snmp/python/netsnmp/client_intf.c;h=bf0e7fe368b5601fe6fec9b832f1272e7ff4909d;hb=upstream#l1468 Maybe using NETSNMP_DS_APPLICATION_ID level and doesn't restore "old_format"? I want to usе more snmplib, as is done in Net-SNMP "apps". Could you point me to where the bindings code, makes what already implemented in snmplib? Thanks! P.S. Before implementing the new features, I would like to simplify and fix current code. -- John Khvatov ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
