JdonFramework need above jdk 1.4.0 This version has passed under Tomcat 4.x/5.x JBoss 3.x/JBoss 4.0

Changes snmp++v3.2.21a
======================

- Fixed: Don't allow SNMP INFORM over SNMPv1.
- Fixed: If a SNMPv3 response was received from a different address/port
  than the request was sent to, no valid mapping address/port <-> enigne id
  was stored, so no communication was possible.

- Added: New overloeaded Oid::set_data() that takes a char array instead
  of ulong array.
- Fixed: The dotted oid string parser no longer accepts strings like
  "1.3.6.$public", "1.3.6$public$" or "1.3.6.$public$1".
- Fixed: Removed a lot of compiler warnings on Windows x64 (with help of
  Sanjay Bhatia). Introduced new type for sockets (SnmpSocket), and
  removed SNMPHANDLE type.
- Changed: Removed global mutex for v3MP and USM.
- Fixed: sockets were not closed if bind failed. (found from John McCaskey)
- Fixed: Engine id discovery did not work when sending SNMPv3 request
  to IPv4 Address over IPv6 socket.
- Fixed: For async SNMPv3 requests that resulted always in a unknown
  engine id or not in time report from the agent the Snmp class continued
  to resend a request to the agent.
- Fixed: USM was not thread safe (found from John McCaskey):
  Changing users from two different threads or changing users
  while messages of these users are processed could cause
  segmentation faults. The following functions of USM now behave
  different than before or require calls to new functions:
  all three get_user() functions, peek_first_user(), peek_next_user(),
  peek_first_luser(), peek_next_luser(), get_user_count().
  If you use any of these functions, read the new documentation in
  usm_v3.h and change your code (like it was done for the QtExample).
- Changed: The functions to set/get the trap listen port of
  CNotifyEventQueue ar no longer static. Use the new functions
  Snmp::notify_set/get_listen_port() instead.
- Removed: Old X11 code, user defined events and timeouts.
- Improved: Counter64 now uses 64 bit integer for math
  operations, instead of long double. 
- Fixed: Zero length UDP packets will no longer trigger
  a transport-level-failed callback.

Changes snmp++v3.2.20a
======================

- Improved: Detect too large received messages.
- Improved: Removed hard coded limit for max number of Vbs
  (PDU_MAX_VBS) in a Pdu object.
- Fixed: Bug in SNMPv3 encryption code which will lead to a
  crash after a random number of encryptions (Stuart Marks).

- Improved: Compilation of address.cpp for Solaris.

Changes snmp++v3.2.19
=====================

- Fixed: Requests with nonzero but wrong security engine id
  now result in a unknown engine id report.
- Added: New functions USM::add_usm_user() and
  new functions to remove engine ids and hosts from
  the v3MP and USM tables.
- Changed: command line arguments of consoleExamples.

Changes snmp++v3.2.18
=====================

- Added: Privacy protocol 3DES. The Auth/Priv interface was
  modifed. (based on patch from Pierre Pacchioni)
- Fixed: Possible memory leak in mp_v3.cpp v3MP::snmp_parse(..).
- Fixed: Uninitialized variable in asn1.cpp asn_parse_length(..).
- Fixed: Uninitialized variables in snmpmsg.cpp 
  SnmpMessage::unload when v3MP::I->snmp_parse() fails.
  (Reported by Rob Crawford)
- Changed: ID of privacy protocol AES128 now is 4
  as required by the RFC.
- Fixed: Vb::get_value(ptr, len, maxlen) may write
  maxlen+1 bytes into ptr buffer (Daniel Suman).
  This function now is  Vb::get_value(ptr, len, maxlen,
  add_null_byte) where the default for add_null_byte
  is false.
- Improved: Workaround for Cisco SNMP agents that set
  request ids to 0x7fffffff in report messages.
- Fixed: Make auth_priv.h/cpp compile if both OpenSSL and
  LibTomCrypt are defined.
- Added: Basic support for VxWorks with PPC603 (Thanks to
  Lee Noll).

Changes snmp++v3.2.17
=====================

- Changed: Updated auth_priv.cpp for LibTomCrypt 1.02
- Changed: Moved logging classes from agent++ into
  snmp++. (Fedja Jeleskovic)
  Function debug_set_logfile() has been removed, use
  DefaultLog::init(new AgentLogImpl("filename")) and
  DefaultLog::log()->set_filter() instead.
  All logging within snmp++ will be moved to the LOG_XXX
  macros and the debugprintf() function will be removed.
- Changed: Renamed "#ifdef alpha" to "#ifdef __osf__". When
  compiling for DigitalUnix/Tru64 make sure, that __osf__
  is defined.

Changes snmp++v3.2.16
=====================

- Improved: notify_register() now returns correct error codes.
- Added: Snmp::start_poll_thread() that starts a new thread
  that polls for async responses and informs/traps. The thread
  will be stopped automatically in the destructor. It also can
  be stopped using Snmp::stop_poll_thread(). (Fedja Jeleskovic)
- Added: New transport layer error code
  SNMP_CLASS_TL_ACCESS_DENIED for (errno == EACCES)
- Improved: new define SNMP_PP_MUTABLE that can be
  defined to mutable for compilers that support
  mutable member variables.
- Changed: renamed OctetStr::set_hex_np_char() to
  set_np_char()
- Improved: get_printable() will return the same buffer
  for each call if the object wasn't changed.
- Added: Pdu::get_max_vbs() to get the value of
  PDU_MAX_VBS at runtime.
- Fixed: Bug in snmperrs.h (Jason Olenhouse)

Changes snmp++v3.2.15
=====================

- Fixed: Bug in asn1.cpp for systems where
  sizeof(long) != sizeof(*long) (Hu Shu)
- Fixed: timeout calculation in
  EventListHolder::SNMPProcessEvents() (Xu Manjiang)
- Fixed: OctetStr::clear() now sets the length to
  zero (Mr. AWD)

- Fixed: Set sin_len of struct sockaddr_in before calling
  bind(). Define CYGPKG_NET_OPENBSD_STACK to enable it.
  (Harald Kuethe)
- Changed: Pdu class checks Vb validity after all
  assignments. It is no longer possible to add
  a Vb that is not valid.
  Some set/get member functions now return bool
  instead of void.

Changes snmp++v3.2.14
=====================

- Improved: Return value of Pdu functions 
  get/set_notify_id and get/set_notify_enterprise. 
  (Marek Malowidzki)
- Fixed: Check return value of new in
  SnmpCollection::operator+=() (Marek Malowidzki)
- Fixed: Setting a byte with Address::operator[] will
  set validity of the object to true.
- Improved: Behaviour of OctetStr::get_printable() for
  non printable strings can now be configured.

Changes snmp++v3.2.13a
======================

- Fixed: Version info was not updated.
- Fixed: Compilation problems with _NO_SNMPv3

- Changed: The user "initial" is no longer automatically
  added to the USM.
- Fixed: Oid class freed memory twice after
  failed call to operator+=().
- Added: Support for AIX 5 (by courtesy of
  Anders Malmborg)

Changes snmp++v3.2.12a

  to allow binding to IPv6 socket.
- Added: AES can now be used with OpenSSL.
- Improved: Compilation under Tru64.
- Fixed: Return code of delete_entry and 
  delete_entries in class USMUserTable returned
  SNMPv3_MP_OK instead SNMPv3_USM_OK.

Changes snmp++v3.2.11
=====================

- Improved: Declared some methods as const
  (Marek Malowidzki).
- Improved: Use shortest possible encoding for
  serializing SNMP messages to improve compatibility
  with buggy/broken SNMP-Tools (Henning Eggers).
- Fixed: Compilation problems on SUN
  (Fabrice Bacchella)
- Improved: declared some methods as const
- Improved: Moved the headers to include/snmp_pp/
  to avoid name colissions.
- Improved: QtExample can receive traps/informs.
- Fixed: Compilation problems with BC++ 5.0
  (Vinoth, Christian Cheney)
- Improved: Added namespace Snmp_pp (Sorin C.)

Changes snmp++v3.2.10a
======================

- Changed: Added two defines _USER_DEFINED_EVENTS
  and _USER_DEFINED_TMEOUTS (enabled by default)
  to switch off the user defined event/timeout queues.
- Improved: Added const to various functions and
  function arguments (Marek Malowidzki)

- Fixed: Added missing DLLOPTs in msec.h (Christian Cheney).

- Improved: The v3MP uses the Snmp object that received
  the message for sending out report messages (needed
  for systems with multiple IP addresses).
  The constructor of the v3MP class was changed, as
  the pointer to the Snmp object is no longer needed
  at construction time.

- Changed: Snmp::notify_register() no longer binds
  to all interfaces, but to the address specified
  in the constructor of the Snmp object.

Changes snmp++v3.2.9d
=====================

- Improved: Removed usage of some multi-threading 
  critical C routines (for example strtok). Although
  on many systems, these routines are multi-threading
  safe, this may not be true for some systems. 

- Fixed: High CPU usage in SNMPProcessEvents() on
  Win32 platform.

- Fixed: SNMPv1 trap sysUpTime TimeTicks where not
  decoded correctly as unsigned integer value, resulting
  in a parse error when sysUpTime > 2^31-1.
- Improved: Log levels.
- Fixed: USMUserNameTable::add_entry() did not update
  the privacy password length.

- Improved: Examples now use the 
  Snmp::socket_startup() on Win32 platforms.

- Added: Two static methods Snmp::socket_startup() and
  Snmp::socket_cleanup() that initialize/cleanup
  Winsock library on WIN32 and do nothing for
  other platforms. The startup method must be
  called before creating Snmp or Address objects.

- Changed: Type of some vars in UsmUserNameTableEntry
  from uchar* to OctetStr. Check if your code uses 
  this struct.
- Changed: engineBoots and engineTime are set to 0 for
  SNMPv3 noAuthNoPriv messages.

Changes snmp++v3.2.8
====================

- Added: Support for OpenSSL.
- Fixed: Compile problem in uxsnmp.cpp. 

Changes snmp++v3.2.7c
=====================

- Fixed: Synchronization problem with mpV3::Cache.
  (Henning Eggers)

- Fixed: Memory leak in OctetStr::from_hex_string.
  (Kent Gibson)
- Changed: EventListHolder::SNMPProcessEvents() 
  param is now in milliseconds (was seconds).

- Fixed: Memory leak if an async SNMPv3 message timed
  out (Henning Eggers).
- Added: Method Snmp::broadcast_discovery() to do
  SNMP broadcast discovery. 
- Improved: Console examples now accept 0 retries,
  removed warnings with gcc 3.2, and v3MP is now
  always created.

- Added: Qt 3.1 example that demonstrates SNMP++v3
  usage with a GUI (Trolltechs Qt 3.1).
- Added: Methods to store, load, and query USM users.
- Improved: Some minor clean-ups.

Changes snmp++v3.2.6b
=====================

- Fixed: GenAddress passed IPv4 addresses as IPv6 
  addresses.
- Changed: By default IDEA is not compiled into 
  SNMP++ by default because patent licensing is
  required for commercial use. Please #define 
  _USE_IDEA if you want to compile IDEA into SNMP++.
  For more details please read also README.v3.

- Fixed: Do not add -Dsun to compile command. If
  you have problems with the SnmpCollection template
  look at the instructions in collect.h. 
- Fixed: Destroy Mutex in ~EventListHolder(). 
- Improved: Lots of cleanups for the address classes.
  This leads to the following incompatibilities to 
  former versions:
  + Enums addr_type and version_type are now inside
    class Address
  + MacAddress, IpxAddress and IpxSockAddress are no
    longer included by default, but can be enabled
    in config_snmp_pp.h 

Changes snmp++v3.2.5d
=====================

- Improved: Made AuthMD5::password_to_key more
  robust against empty passwords.
- Changed: The Win32 DLL export macros now use
  SNMP_PP_DLL instead _USRDLL.
- Changed: Moved VC++ project files in a 
  separate package. 

- Improved: Minor issues with IPv6 support.
- Improved: Socket handling.

- Fixed: uxsnmp.cpp: Detecting error from socket()
  return values.

- Fixed: Moved SNMPAddInput() SNMPRemoveInput()
  SNMPAddTimeout and SNMPREmoveTimeout to the
  class EventListHolder
- Fixed: Unique Id generation in CUDEventQueue and
  CUTEventQueue.
- Fixed: Bugs in Vb::get_value() methods that take a
  char* or unsigned char* as argument
- Added: operator+() for Oids (Alexander Gutkin)
- Improved: Cleanups in queues 

Changes snmp++v3.2.4a
=====================

- Improved: Synchronous and asynchronous SNMP
  request processing is now separated. Thus,
  the global event lists have been removed. 
  Each Snmp class now holds its own event 
  lists.
  To eliminate the use of global event lists
  a new class EventListHolder was defined. Two
  new files eventListHolder.h and 
  eventListHolder.cpp contain now declaration
  and definition of that class respectively.
  That new class is a container of former
  eventList global data structure and former
  global user defined events, user-defined 
  timeouts, notifications and all outstanding
  messages. (LiorK)
- Improved: collect.h (Bill McKinnon)
- Improved: FreeBSD 5.0 support.

- Added: Makefile.gcc_solaris for compilation
  with GNU C++ compiler on Solaris.	


Changes snmp++v3.2.3b
=====================

- Fixed: Counter64::get_printable() could print
  negative values (Yakov Y.)

- Note: New Makefiles assume that you have
  defined _USE_LIBTOMCRYPT when a "crypt"
  directory is present in the same folder as
  the "snmp++" and "agent++" directories. 
- Fixed: Compilation problems without _SNMPv3
  defined.
- Fixed: PDU length computation for encrypted
  SNMPv3 PDUs.

- Improved: New v3MP class.
- Fixed: Estimated length calculation for 
  encoded PDU.


Changes snmp++v3.2.2d
=====================

- Fixed: Possible timeouts under heavy load
  in a multi-threaded environment. 
  [Pavel Spakovsky]

- Fixed: DLL support for VC++ did not allow
  static linking.
- Added: Computation of BER encoded length of
  a Pdu. 

- Added: VC++.NET project files and fixed DLL
  support.

- Fixed: Errors in Counter64::c64_to_ld() and
  Counter64::ld_to_c64() [Mikhail Evstiounin]

- Improved: Prepared for AES usage replacing
  libDES. 
- Fixed: Compilation problems with G++3.2
  (needs updated libDES download).

Changes snmp++v3.2.1d
=====================

- Fixed: Memory leak (40 bytes) when adding an
  user to usm.
- Improved: Some cleanups (#include, const).
- Fixed: Due to possible race condition in
  MyMakeReqId() (uxsnmp.cpp) two requests could
  get the same request id. 
- Fixed: const casting caused problems with
  AIX compiler.

Changes snmp++v3.2.1
====================

- Improved: Use zero length user name for
  SNMPv3 discovery.
- Lots of cleanups.

===================

- Fixed: Compilation problem with address.cpp on
  Solaris. 

Changes snmp++v3.2
==================

- Added: IPv6 support.
- Improved: moved the USM functions into the class
  USM. To add or delete users, you will now have to
  do the following (see usm_v3.h for more details):
     Usm *usm = mpGetUsm();
     usm->add_usm_user(...);
     usm->delete_usm_user(...);

- Fixed: Possible SegFault in notify queue
  (Lior Klibansky)
- Fixed: Timeout problem in event list (Don Dietz)
- Fixed: Don't use isdigit() for BCC (Eric Zerbib)
- Added: clear() method to SnmpCollection
- Fixed: added clone() method to Pdu class, so
  SnmpCollection<Pdu> will work again.
- Added: Make notify socket decriptor available in
  Snmp class (Don Dietz)

Changes snmp++v3.1.6c
=====================

- Fixed: mp_v3.cpp: Unsigned integer values were
  not BER decoded correctly for SNMPv3 messages.
- Fixed: Some errors when compiling with -ansi
- Improved: Class AuthPriv does no longer depend
  on USM. 

Changes snmp++v3.1.6b
=====================

- Added: BCC32 support.
- Added: DLLOPT decoration for debugprintf.

Changes snmp++v3.1.6a
=====================
