CHANGE LOG OF SNMP4J ==================== [2008-04-03] Version 1.9.1c: * Fixed: Missing PDUv1.clone() which could lead to wrong SNMPv1 trap PDU encoding. * Fixed: Possible deadlock race condition when processing sync requests with retry > 0. * Improved: Pending async requests will be removed after timeout even if the response listener did not call Snmp.cancel. * Fixed: TableUtils did not return all rows if request PDUs had to be splitted because of too much columns. [2008-03-27] Version 1.9.1b: * Fixed: Transport not copied in Snmp.PendingRequest which could cause wrong transport usage when processing retries. [2008-03-25] Version 1.9.1a: * Fixed: Async request processing for broadcasts (regression bug in 1.9.1 which prevented mutliple responses for a single async request). [2008-03-18] Version 1.9.1: * Improved: OID parsing from string now supports embedded string to OID conversion, for example the following OIDs are equal: a = new OID("1.3.6.2.1.5.'hal.'.'''.'lo'.1"); b = new OID("1.3.6.2.1.5.104.97.108.46.39.108.111.1"); * Improved: Added factory pattern for creating PDU for incoming messages parsed by message processing models. * Fixed: Null LogLevel returned by JavaLogAdapter.getLogLevel. * Fixed: With async request processing and retry>0 there could have been a race condition where a response event had been generated twice for a request. * Fixed: ArgumentParser option multi parameter support which failed to parse options like "-option param1 param2" correctly. * Changed: MessageDispatcherImpl can now be used to register more than one transport mapping per address class (UDP/TCP). Nevertheless, only the first registered one will be used for sending SNMP messages if no specific transport mapping is given. * Improved: Target is cloned when used internally by Snmp instance to avoid errors through concurrent target usage. [2008-01-31] Version 1.9: * Improved: PDU.add(VariableBinding) no longer clones VariableBindings while adding it if the contained variable is dynamic. Instead VariableBinding.setVariable clones the set variable always as well the oid set by setOid(OID). * Improved: Added factories for thread and timer instances configurable through SNMP4JSettings class. * Improved: Created interfaces for ThreadPool (WorkerPool) and thread of execution (WorkerTask) as well as Timer (CommonTimer) for better Java EE intergration. * Added: ArgumentParser for simple command line parsing. * Fixed: Local engine ID could not be set for simple PDU request for the command line tool. [2007-11-06] Version 1.9 RC2: * Fixed: Walk modus of console example. * Added: -Ocs and -Ods to create and dump subtree snapshot files. [2007-10-18] Version 1.9 RC1: * Fixed: LogFactory.getLogFactory() returned null if log factory has not been initialized yet. Now a new instance of LogFactory is returned instead. * Fixed: Typo in Snmp JavaDoc (getPdu() -> getPDU()). * Added: Hook-up method in DefaultTCPTransportMapping to allow setting socket options by extending the class and overwriting the setSocketOptions method. * Added: TripleDES-EDE privacy protocol implementation. * Changed: SecurityProtocol interface to allow dynamic key extension. * Fixed: Race condition in DefaultTCPTransportMapping. [2007-05-04] Version 1.8.2: * Fixed: Null.clone() did not copy/preserve syntax. * Fixed: MPv3.addEngineID added engine ID to the local cache although if it matched the local engine ID. [2007-04-23] Version 1.8.1a: * Fixed: No error was reported by TableUtils when sending of a request failed. * Fixed: MPv3.removeEngineID fired "engine ID added" event. [2007-03-12] Version 1.8.1: * Fixed: Race condition in DefaultTCPTransportMapping that could cause message loss because messages are accidentially never send (because at the same time another message came in). * Improved: Snmp.addNotificationListener(..) sets the connection timeout to 0 for TCP transport mappings. * Fixed: Snmp.removeNotificationListener(..) caused memory leak because it did not deregister the notification transport mapping properly. * Fixed/Improved: Several code cosmetics and Serializable issues. * Improved: REPORT messages are now sent over the same transport mapping as the message reported on has been received. This improves firewall interoperability. [2007-02-01] Version 1.8: * Fixed: Race condition with sync requests in Snmp.send that could cause a deadlock. * Fixed: Added missing serialVersionUIDs. * Changed: PduHandleCallback.pduHandleAssigned(..) to use Object as type of the PDU reference. [2007-01-08] Version 1.8 RC1: * Changed: Variable is now an interface and the former abstract class implementation is now moved to AbstractVariable. Serialized Variables from 1.7.x or earliers released can be deserialized with 1.8 because the Variable interface defines the same serialVersionUID as the former Variable abstract class. * Fixed: MessageDispatcherImpl.getMessageProcessingModel no longer throws an ArrayIndexOutOfBoundsException when the requested model is not known. * Added: GenericAddress constants for the default address types "udp", "tcp", and "ip". * Fixed: OctetString.fromSubIndex for implied length values. * Added: Constants for default command responder and notification receiver ports in SnmpConstants class. * Added: Append constructor for OID class, to facilitate creating an instance OID from a class OID and an index OID. * Improved: DefaultTcpTransportMapping can now also reconnect if its connection is in state "unconnected". * Fixed: OctetString.startsWith did not work if prefix length did not match the string's length. * Added: Option (-m) to set maxMessageResponseSize for SNMPv3 requests in console example. * Improved: Clarified and implemented TODOs left from earlier versions. * Fixed: IllegalStateException seldom occured in a race condition while waiting for a sync response in Snmp.send(..) or when canceled an async response while a retry was started. * Improved: Performance of message sending and receiving due to less (narrow) synchronization. * Added: -l option to SnmpRequest console example to allow setting the local engine ID to avoid engine ID conflicts. * Added: -b option to set the engine boots counter for the console example (SnmpRequest). * Added: TreeUtils to conveniently walk sub-trees. * Fixed: Bug in LogLevel class causing incorrect log levels to be used in some cases when converting from a levels string representation. * Improved: JavaLogAdapter DEBUG level from SNMP4J (Log4J) now maps to FINE in Java logging. * Added: LogFactory can now be configured through the system property "snmp4j.LogFactory" with the factories class name. * Added: LogProxy for implementing late logger binding. * Changed: BERSerializable no longer extends Serializable. * Added: Security check for transport not listening when sending confirmed PDU. [2006-10-07] Version 1.7.6a: * Fixed: Possible deadlock in ThreadPool when stopping a busy thread pool. * Added: SMIConstants.SYNTAX_BITS to map to SMIConstants.SYNTAX_OCTET_STRING. * Added: TableUtils.destroyRow(..). * Fixed: Opaque.clone() was missing. [2006-09-04] Version 1.7.5: * Changed: VariableBinding(OID, Variable) now checks OID for not being null. * Fixed: MessageDispatcherImpl.addAuthenticationFailureListener did not work. * Fixed: OctetString.split(OctetString, OctetString). [2006-08-19] Version 1.7.4a: * Fixed: Concurrent access to the internal server thread during close() calls does no longer cause a NullPointerException. The synchronization that caused a deadlock in 1.7.4 has been removed again. * Added: Support for the obsolete SMI type BIT STRING for compatib
