/* 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().
|
