/* CHANGELOG FOR PORTMIDI * * 19Oct09 Roger Dannenberg * - Changes dynamic library names from portmidi_d to portmidi to * be backward-compatible with programs expecting a library by * the old name. * * 04Oct09 Roger Dannenberg * - Converted to using Cmake. * - Renamed static and dynamic library files to portmidi_s and portmidi_d * - Eliminated VC9 and VC8 files (went back to simply test.vcproj, etc., * use Cmake to switch from the provided VC9 files to VC8 or other) * - Many small changes to prepare for 64-bit architectures (but only * tested on 32-bit machines) * * 16Jun09 Roger Dannenberg * - Started using Microsoft Visual C++ Version 9 (Express). Converted * all *-VC9.vcproj file to *.vcproj and renamed old project files to * *-VC8.proj. Previously, output from VC9 went to special VC9 files, * that breaks any program or script looking for output in release or * debug files, so now both compiler version output to the same folders. * Now, debug version uses static linking with debug DLL runtime, and * release version uses static linking with statically linked runtime. * Converted to Inno Setup and worked on scripts to make things build * properly, especially pmdefaults. * * 02Jan09 Roger Dannenberg * - Created Java interface and wrote PmDefaults application to set * values for Pm_GetDefaultInputDeviceID() and * Pm_GetDefaultOutputDeviceID(). Other fixes. * * 19Jun08 Roger Dannenberg and Austin Sung * - Removed USE_DLL_FOR_CLEANUP -- Windows 2000 through Vista seem to be * fixed now, and can recover if MIDI ports are left open * - Various other minor patches * * 17Jan07 Roger Dannenberg * - Lots more help for Common Lisp user in pm_cl * - Minor fix to eliminate a compiler warning * - Went back to single library in OS X for both portmidi and porttime * * 16Jan07 Roger Dannenberg * - OOPS! fixed bug where short messages all had zero data * - Makefile.osx static library build now makes universal (i386 + ppc) * binaries * * 15Jan07 Roger Dannenberg * - multiple rewrites of sysex handling code to take care of * error-handling, embedded messages, message filtering, * driver bugs, and host limitations. * - fixed windows to use dwBufferLength rather than * dwBytesRecorded for long buffer output (fix by Nigel Brown) * - Win32 MME code always appends an extra zero to long buffer * output to work around a problem with earlier versions of Midi Yoke * - Added mm, a command line Midi Monitor to pm_test suite * - Revised copyright notice to match PortAudio/MIT license (requests * are moved out of the license proper and into a separate paragraph) * * 18Oct06 Roger Dannenberg * - replace FIFO in pmutil with Light Pipe-based multiprocessor-safe alg. * - replace FIFO in portmidi.c with PmQueue from pmutil * * 07Oct06 cpr & Roger Dannenberg * - overhaul of CoreMIDI input to handle running status and multiple * - messages per packet, with additional error detection * - added Leigh Smith and Rick Taube support for Common Lisp and * - dynamic link libraries in OSX * - initialize static global seq = NULL in pmlinuxalsa.c * * 05Sep06 Sebastien Frippiat * - check if (ALSA) seq exists before closing it in pm_linuxalsa_term() * * 05Sep06 Andreas Micheler and Cecilio * - fixed memory leak by freeing someo objects in pm_winmm_term() * - and another leak by freeing descriptors in Pm_Terminate() * * 23Aug06 RBD * - various minor fixes * * 04Nov05 Olivier Tristan * - changes to OS X to properly retrieve real device name on CoreMidi * * 19Jul05 Roger Dannenberg * - included pmBufferMaxSize in Pm_GetErrorText() * * 23Mar05 Torgier Strand Henriksen * - cleaner termination of porttime thread under Linux * * 15Nov04 Ben Allison * - sysex output now uses one buffer/message and reallocates buffer * - if needed * - filters expanded for many message types and channels * - detailed changes are as follows: * ------------- in pmwinmm.c -------------- * - new #define symbol: OUTPUT_BYTES_PER_BUFFER * - change SYSEX_BYTES_PER_BUFFER to 1024 * - added MIDIHDR_BUFFER_LENGTH(x) to correctly count midihdr buffer length * - change MIDIHDR_SIZE(x) to (MIDIHDR_BUFFER_LENGTH(x) + sizeof(MIDIHDR)) * - change allocate_buffer to use new MIDIHDR_BUFFER_LENGTH macro * - new macros for MIDIHDR_SYSEX_SIZE and MIDIHDR_SYSEX_BUFFER_LENGTH * - similar to above, but counts appropriately for sysex messages * - added the following members to midiwinmm_struct for sysex data: * - LPMIDIHDR *sysex_buffers; ** pool of buffers for sysex data ** * - int num_sysex_buffers; ** how many sysex buffers ** * - int next_sysex_buffer; ** index of next sysexbuffer to send ** * - HANDLE sysex_buffer_signal; ** to wait for free sysex buffer ** * - duplicated allocate_buffer, alocate_buffers and get_free_output_buffer * - into equivalent sysex_buffer form * - changed winmm_in_open to initialize new midiwinmm_struct members and * - to use the new allocate_sysex_buffer() function instead of * - allocate_buffer() * - changed winmm_out_open to initialize new members, create sysex buffer * - signal, and allocate 2 sysex buffers * - changed winmm_out_delete to free sysex buffers and shut down the sysex * - buffer signal * - create new function resize_sysex_buffer which resizes m->hdr to the * - passed size, and corrects the midiwinmm_struct accordingly. * - changed winmm_write_byte to use new resize_sysex_buffer function, * - if resize fails, write current buffer to output and continue * - changed winmm_out_callback to use buffer_signal or sysex_buffer_signal * - depending on which buffer was finished * ------------- in portmidi.h -------------- * - added pmBufferMaxSize to PmError to indicate that the buffer would be * - too large for the underlying API * - added additional filters * - added prototype, documentation, and helper macro for Pm_SetChannelMask * ------------- in portmidi.c -------------- * - added pm_status_filtered() and pm_realtime_filtered() functions to * separate filtering logic from buffer logic in pm_read_short * - added Pm_SetChannelMask function * - added pm_channel_filtered() function * ------------- in pminternal.h -------------- * - added member to PortMidiStream for channel mask * * 25May04 RBD * - removed support for MIDI THRU * - moved filtering from Pm_Read to pm_enqueue to avoid buffer ovfl * - extensive work on Mac OS X port, especially sysex and error handling * * 18May04 RBD * - removed side-effects from assert() calls. Now you can disable assert(). * - no longer check pm_hosterror everywhere, fixing a bug where an open * failure could cause a write not to work on a previously opened port * until you call Pm_GetHostErrorText(). * 16May04 RBD and Chris Roberts * - Some documentation wordsmithing in portmidi.h * - Dynamically allocate port descriptor structures * - Fixed parameter error in midiInPrepareBuffer and midiInAddBuffer. * * 09Oct03 RBD * - Changed Thru handling. Now the client does all the work and the client * must poll or read to keep thru messages flowing. * * 31May03 RBD * - Fixed various bugs. * - Added linux ALSA support with help from Clemens Ladisch * - Added Mac OS X support, implemented by Jon Parise, updated and * integrated by Andrew Zeldis and Zico Kolter * - Added latency program to build histogram of system latency using PortTime. * * 30Jun02 RBD Extensive rewrite of sysex handling. It works now. * Extensive reworking of error reporting and error text -- no * longer use dictionary call to delete data; instead, Pm_Open * and Pm_Close clean up before returning an error code, and * error text is saved in a system-independent location. * Wrote sysex.c to test sysex message handling. * * 15Jun02 BCT changes: * - Added pmHostError text handling. * - For robustness, check PortMidi stream args not NULL. * - Re-C-ANSI-fied code (changed many C++ comments to C style) * - Reorganized code in pmwinmm according to input/output functionality (made * cleanup handling easier to reason about) * - Fixed Pm_Write calls (portmidi.h says these should not return length but Pm_Error) * - Cleaned up memory handling (now system specific data deleted via dictionary * call in PortMidi, allows client to query host errors). * - Added explicit asserts to verify various aspects of pmwinmm implementation behaves as * logic implies it should. Specifically: verified callback routines not reentrant and * all verified status for all unchecked Win32 MMedia API calls perform successfully * - Moved portmidi initialization and clean-up routines into DLL to fix Win32 MMedia API * bug (i.e. if devices not explicitly closed, must reboot to debug application further). * With this change, clients no longer need explicitly call Pm_Initialize, Pm_Terminate, or * explicitly Pm_Close open devices when using WinMM version of PortMidi. * * 23Jan02 RBD Fixed bug in pmwinmm.c thru handling * * 21Jan02 RBD Added tests in Pm_OpenInput() and Pm_OpenOutput() to prevent * opening an input as output and vice versa. * Added comments and documentation. * Implemented Pm_Terminate(). * */
