1 /* CHANGELOG FOR PORTMIDI
3 * 19Oct09 Roger Dannenberg
4 * - Changes dynamic library names from portmidi_d to portmidi to
5 * be backward-compatible with programs expecting a library by
6 * the old name.
8 * 04Oct09 Roger Dannenberg
9 * - Converted to using Cmake.
10 * - Renamed static and dynamic library files to portmidi_s and portmidi_d
11 * - Eliminated VC9 and VC8 files (went back to simply test.vcproj, etc.,
12 * use Cmake to switch from the provided VC9 files to VC8 or other)
13 * - Many small changes to prepare for 64-bit architectures (but only
14 * tested on 32-bit machines)
16 * 16Jun09 Roger Dannenberg
17 * - Started using Microsoft Visual C++ Version 9 (Express). Converted
18 * all *-VC9.vcproj file to *.vcproj and renamed old project files to
19 * *-VC8.proj. Previously, output from VC9 went to special VC9 files,
20 * that breaks any program or script looking for output in release or
21 * debug files, so now both compiler version output to the same folders.
22 * Now, debug version uses static linking with debug DLL runtime, and
23 * release version uses static linking with statically linked runtime.
24 * Converted to Inno Setup and worked on scripts to make things build
25 * properly, especially pmdefaults.
27 * 02Jan09 Roger Dannenberg
28 * - Created Java interface and wrote PmDefaults application to set
29 * values for Pm_GetDefaultInputDeviceID() and
30 * Pm_GetDefaultOutputDeviceID(). Other fixes.
32 * 19Jun08 Roger Dannenberg and Austin Sung
33 * - Removed USE_DLL_FOR_CLEANUP -- Windows 2000 through Vista seem to be
34 * fixed now, and can recover if MIDI ports are left open
35 * - Various other minor patches
37 * 17Jan07 Roger Dannenberg
38 * - Lots more help for Common Lisp user in pm_cl
39 * - Minor fix to eliminate a compiler warning
40 * - Went back to single library in OS X for both portmidi and porttime
42 * 16Jan07 Roger Dannenberg
43 * - OOPS! fixed bug where short messages all had zero data
44 * - Makefile.osx static library build now makes universal (i386 + ppc)
45 * binaries
47 * 15Jan07 Roger Dannenberg
48 * - multiple rewrites of sysex handling code to take care of
49 * error-handling, embedded messages, message filtering,
50 * driver bugs, and host limitations.
51 * - fixed windows to use dwBufferLength rather than
52 * dwBytesRecorded for long buffer output (fix by Nigel Brown)
53 * - Win32 MME code always appends an extra zero to long buffer
54 * output to work around a problem with earlier versions of Midi Yoke
55 * - Added mm, a command line Midi Monitor to pm_test suite
56 * - Revised copyright notice to match PortAudio/MIT license (requests
57 * are moved out of the license proper and into a separate paragraph)
59 * 18Oct06 Roger Dannenberg
60 * - replace FIFO in pmutil with Light Pipe-based multiprocessor-safe alg.
61 * - replace FIFO in portmidi.c with PmQueue from pmutil
63 * 07Oct06 cpr & Roger Dannenberg
64 * - overhaul of CoreMIDI input to handle running status and multiple
65 * - messages per packet, with additional error detection
66 * - added Leigh Smith and Rick Taube support for Common Lisp and
67 * - dynamic link libraries in OSX
68 * - initialize static global seq = NULL in pmlinuxalsa.c
70 * 05Sep06 Sebastien Frippiat
71 * - check if (ALSA) seq exists before closing it in pm_linuxalsa_term()
73 * 05Sep06 Andreas Micheler and Cecilio
74 * - fixed memory leak by freeing someo objects in pm_winmm_term()
75 * - and another leak by freeing descriptors in Pm_Terminate()
77 * 23Aug06 RBD
78 * - various minor fixes
80 * 04Nov05 Olivier Tristan
81 * - changes to OS X to properly retrieve real device name on CoreMidi
83 * 19Jul05 Roger Dannenberg
84 * - included pmBufferMaxSize in Pm_GetErrorText()
86 * 23Mar05 Torgier Strand Henriksen
87 * - cleaner termination of porttime thread under Linux
89 * 15Nov04 Ben Allison
90 * - sysex output now uses one buffer/message and reallocates buffer
91 * - if needed
92 * - filters expanded for many message types and channels
93 * - detailed changes are as follows:
94 * ------------- in pmwinmm.c --------------
95 * - new #define symbol: OUTPUT_BYTES_PER_BUFFER
96 * - change SYSEX_BYTES_PER_BUFFER to 1024
97 * - added MIDIHDR_BUFFER_LENGTH(x) to correctly count midihdr buffer length
98 * - change MIDIHDR_SIZE(x) to (MIDIHDR_BUFFER_LENGTH(x) + sizeof(MIDIHDR))
99 * - change allocate_buffer to use new MIDIHDR_BUFFER_LENGTH macro
100 * - new macros for MIDIHDR_SYSEX_SIZE and MIDIHDR_SYSEX_BUFFER_LENGTH
101 * - similar to above, but counts appropriately for sysex messages
102 * - added the following members to midiwinmm_struct for sysex data:
103 * - LPMIDIHDR *sysex_buffers; ** pool of buffers for sysex data **
104 * - int num_sysex_buffers; ** how many sysex buffers **
105 * - int next_sysex_buffer; ** index of next sysexbuffer to send **
106 * - HANDLE sysex_buffer_signal; ** to wait for free sysex buffer **
107 * - duplicated allocate_buffer, alocate_buffers and get_free_output_buffer
108 * - into equivalent sysex_buffer form
109 * - changed winmm_in_open to initialize new midiwinmm_struct members and
110 * - to use the new allocate_sysex_buffer() function instead of
111 * - allocate_buffer()
112 * - changed winmm_out_open to initialize new members, create sysex buffer
113 * - signal, and allocate 2 sysex buffers
114 * - changed winmm_out_delete to free sysex buffers and shut down the sysex
115 * - buffer signal
116 * - create new function resize_sysex_buffer which resizes m->hdr to the
117 * - passed size, and corrects the midiwinmm_struct accordingly.
118 * - changed winmm_write_byte to use new resize_sysex_buffer function,
119 * - if resize fails, write current buffer to output and continue
120 * - changed winmm_out_callback to use buffer_signal or sysex_buffer_signal
121 * - depending on which buffer was finished
122 * ------------- in portmidi.h --------------
123 * - added pmBufferMaxSize to PmError to indicate that the buffer would be
124 * - too large for the underlying API
125 * - added additional filters
126 * - added prototype, documentation, and helper macro for Pm_SetChannelMask
127 * ------------- in portmidi.c --------------
128 * - added pm_status_filtered() and pm_realtime_filtered() functions to
129 * separate filtering logic from buffer logic in pm_read_short
130 * - added Pm_SetChannelMask function
131 * - added pm_channel_filtered() function
132 * ------------- in pminternal.h --------------
133 * - added member to PortMidiStream for channel mask
135 * 25May04 RBD
136 * - removed support for MIDI THRU
137 * - moved filtering from Pm_Read to pm_enqueue to avoid buffer ovfl
138 * - extensive work on Mac OS X port, especially sysex and error handling
140 * 18May04 RBD
141 * - removed side-effects from assert() calls. Now you can disable assert().
142 * - no longer check pm_hosterror everywhere, fixing a bug where an open
143 * failure could cause a write not to work on a previously opened port
144 * until you call Pm_GetHostErrorText().
145 * 16May04 RBD and Chris Roberts
146 * - Some documentation wordsmithing in portmidi.h
147 * - Dynamically allocate port descriptor structures
148 * - Fixed parameter error in midiInPrepareBuffer and midiInAddBuffer.
150 * 09Oct03 RBD
151 * - Changed Thru handling. Now the client does all the work and the client
152 * must poll or read to keep thru messages flowing.
154 * 31May03 RBD
155 * - Fixed various bugs.
156 * - Added linux ALSA support with help from Clemens Ladisch
157 * - Added Mac OS X support, implemented by Jon Parise, updated and
158 * integrated by Andrew Zeldis and Zico Kolter
159 * - Added latency program to build histogram of system latency using PortTime.
161 * 30Jun02 RBD Extensive rewrite of sysex handling. It works now.
162 * Extensive reworking of error reporting and error text -- no
163 * longer use dictionary call to delete data; instead, Pm_Open
164 * and Pm_Close clean up before returning an error code, and
165 * error text is saved in a system-independent location.
166 * Wrote sysex.c to test sysex message handling.
168 * 15Jun02 BCT changes:
169 * - Added pmHostError text handling.
170 * - For robustness, check PortMidi stream args not NULL.
171 * - Re-C-ANSI-fied code (changed many C++ comments to C style)
172 * - Reorganized code in pmwinmm according to input/output functionality (made
173 * cleanup handling easier to reason about)
174 * - Fixed Pm_Write calls (portmidi.h says these should not return length but Pm_Error)
175 * - Cleaned up memory handling (now system specific data deleted via dictionary
176 * call in PortMidi, allows client to query host errors).
177 * - Added explicit asserts to verify various aspects of pmwinmm implementation behaves as
178 * logic implies it should. Specifically: verified callback routines not reentrant and
179 * all verified status for all unchecked Win32 MMedia API calls perform successfully
180 * - Moved portmidi initialization and clean-up routines into DLL to fix Win32 MMedia API
181 * bug (i.e. if devices not explicitly closed, must reboot to debug application further).
182 * With this change, clients no longer need explicitly call Pm_Initialize, Pm_Terminate, or
183 * explicitly Pm_Close open devices when using WinMM version of PortMidi.
185 * 23Jan02 RBD Fixed bug in pmwinmm.c thru handling
187 * 21Jan02 RBD Added tests in Pm_OpenInput() and Pm_OpenOutput() to prevent
188 * opening an input as output and vice versa.
189 * Added comments and documentation.
190 * Implemented Pm_Terminate().
