April 9, 2013 ------------- Changes for the 1.1.0 release (vs 1.0.2) are listed below. Unless otherwise indicated these changes have been made since January 2013. The focus has been on general clean-up, fixing bugs, compiler errors and warnings, and fixing issues on 64 bit platforms. A few improvements such as support for OSC arrays, functions for setting broadcast and reuse socket options have been added. This update merges changes from the openFrameworks version of oscpack. - Added support for arrays in messages (see OscUnitTests.cpp for example usage). (patch thanks to Tim Blechmann) - Fixed bugs relating to 64 bit usage (e.g. crashes in 64 bit builds on OS X). - Some member functions that previously used the "int" or "unsigned long" type for parameters or return values now use std::size_t (platform-defined) or osc_bundle_element_size_t (a.k.a. int32). This change was made to better support 64 bit platforms. See SVN revision 70 for details. - The previous point introduces a breaking change on Linux/x86_64 for callers of AsBlob() and AsBlobUnchecked(): The type of the second argument (the "size" argument) to ReceivedMessageArgument::AsBlob() and ReceivedMessageArgument::AsBlobUnchecked() has changed from unsigned long & to osc_bundle_element_size_t (an int32). You should declare your size argument variables as osc_bundle_element_size_t to avoid incompatibilities between 32 and 64 bit builds. - Note that oscpack does not support packets larger than 0x7FFFFFFC (see comments in class ReceivedPacket for details). - Oscpack defines an osc::Nil value used for sending the nil message argument value. This conflicts with Objective-C. Therefore osc::Nil is no longer defined in Obj-C++ code. There is now an osc::OscNil value, which should be preferred. osc::Nil is still available when writing C++. (fix thanks to openFrameworks) - Added UdpSocket::SetEnableBroadcast(). This needs to be called to enable sending to the broadcast address on some platforms (e.g. Mac OS X). (thanks to openFrameworks) - Added UdpSocket::SetAllowReuse(). This is useful for sharing sockets on some platforms (Mac?), and not so useful on other platforms. (thanks to openFrameworks) - Added IpEndpointName::IsMulticastAddress() (2010) - Cleaned up C++ header usage and std:: namespace usage to be more standards compliant (fixes issues on recent compilers such as clang and gcc4.6). - Improved host endianness detection. Should auto-detect endianness on most platforms now. (thanks to Tim Blechmann for help with this) - Fixed two memory leaks: (1) in OscPrintReceivedElements.cpp when printing time tag message arguments (thanks to Gwydion ap Dafydd). (2) in the posix SocketReceiveMultiplexer::Run() method if an exception was thrown while listening. - Fixed bug in posix SocketReceiveMultiplexer::Run() that would cause packets to stop being received if select() returned EINTR. (thanks to Björn Wöldecke) - Updated and improved Makefile to avoid redundant re-linking (thanks to Douglas Mandell) - Added CMakeLists.txt CMake build file (2010, thanks to David Doria) - Switched license to plain MIT license with non binding request for contribution of improvements (same as current PortAudio boilerplate). See LICENSE file. Thanks to Tim Blechmann, Rob Canning, Gwydion ap Dafydd, David Doria, Christopher Delaney, Jon McCormack, Douglas Mandell, Björn Wöldecke, all the guys at openFrameworks, and everyone who reported bugs, submitted patches and helped out with testing this release. Thanks to Syneme at the University of Calgary for providing financial support for the 1.1.0 update. September 28, 2005 ------------------ Compared to the previous official snapshot (November 2004) the current version of oscpack includes a re-written set of network classes and some changes to the syntax of the networking code. It no longer uses threads, which means that you don't need to use sleep() if you are writing a simple single-threaded server, or you need to spawn your own threads in a more complex application. The list below summarises the changes if you are porting code from the previous release. - There are no longer any threads in oscpack. if you need to set up an asynchronous listener you can create your own thread and call Run on an instance of SocketReceiveMultiplexer or UdpListeningReceiveSocket (see ip/UdpSocket.h) yourself. - Host byte order is now used for network (IP) addresses - Functions which used to take two parameters now take an instance of IpEndpointName (see ip/IpEndpointName.h) this class has a number of convenient constructors for converting numbers and strings to internet addresses. For example there is one which takes a string and another that take the dotted address components as separate parameters. - The UdpTransmitPort class, formerly in UdpTransmitPort.h, is now called UdpTransmitSocket, which is simply a convenience class derived from UdpSocket (see ip/UdpSocket.h). Where you used to use the constructor UdpTransmitPort( address, port) now you can use UdpTransmitSocket( IpEndpointName( address, port ) ) or you can any of the other possible ctors to IpEndpointName () (see above). The Send() method is unchanged. - The packet listener base class is now located in ip/PacketListener.h instead of PacketListenerPort.h. The ProcessPacket method now has an additional parameter indicating the remote endpoint - The preferred way to set up listeners is with SocketReceiveMultiplexer (in ip/UdpSocket.h), this also allows attaching periodic timers. For simple applications which only listen to a single socket with no timers you can use UdpListeningReceiveSocket (also in UdpSocket.h) See osc/OscReceiveTest.cpp or osc/OscDump.cpp for examples of this. This is more or less equivalent to the UdpPacketListenerPort object in the old oscpack versions except that you need to explicitly call Run() before it will start receiving packets and it runs in the same thread, not a separate thread so Run() won't usually return. - Explicit calls to InitializeNetworking() and TerminateNetworking() are no longer required for simple applications (more complex windows applications should instantiate NetworkInitializer in main() or WinMain (see ip/NetworkingUtils.h/.cpp) - The OscPacketListener base class (OscPacketListener.h) was added to make traversing OSC packets easier, it handles bundle traversal automatically so you only need to process messages in your derived classes. - On Windows be sure to link with ws2_32.lib or you will see a linker error about WSAEventSelect not being found. Also you will need to link with winmm.lib for timeGetTime()
