Improved connection error handling:

* Expose actual system error codes via client interface
  instead of just -1 whenever a syscall failed.

* Added new client interface function:
    lscp_client_connection_lost();
  for checking whether client lost connection to server.

17 capela 3400 0.6.0 2017-12-12 An Autumn'17 release.
18    
19 capela 3043 0.5.8 2016-11-14 A Fall'16 release.
20    
21 capela 2487 0.5.7 2013-12-31 Use getaddrinfo() instead of deprecated gethostbyname().
22 capela 1813
23 capela 2422 Update on newer autoconf macros (m4).
24    
25 capela 2418 Fixes for building for Windows with configure and make.
26    
27 persson 2132 Makefile fixes for building in separate directory.
28    
29 schoenebeck 2454 Autoconf fix: AC_CONFIG_HEADER obsolete error (fixes #194).
30    
31 persson 2132 0.5.6 2009-08-01 Fixed locale related parser bug (fixes #59).
32    
33 capela 1813 Added new client interface functions, for managing
34     the global limit of maximum voices and disk streams:
35     lscp_get_voices(), lscp_set_voices(), lscp_get_streams(),
36     lscp_set_streams().
37    
38     _lscp_device_port_info_query(): take port parameter
39 schoenebeck 1711 "NAME" into the result list.
40 schoenebeck 1692
41 schoenebeck 1711 Bugfix: _lscp_client_evt_proc() dropped LSCP events.
42    
43 schoenebeck 1692 Bugfix in lscp_client_subscribe(): only the first
44 schoenebeck 1690 lscp_client_subscribe() call succeeded (per client),
45     all subsequent ones failed.
46    
47     Added support for new (un)subscribable events:
48 schoenebeck 1689 LSCP_EVENT_CHANNEL_MIDI
49 schoenebeck 1697 LSCP_EVENT_DEVICE_MIDI
50 schoenebeck 1689 Caution: the bitflag approach for the event variable
51     is now abondoned, since otherwise we would soon hit the
52     limit of the bit range. The bitflag approach will
53     remain for events older at this point (that is all
54     events which occupy the lower 16 bits), but this new
55     and all following events will simply be enumared along
56     the upper 16 bits.
57    
58     Added new client interface function, for renaming
59 schoenebeck 1665 effect send entities:
60     lscp_set_fxsend_name();
61    
62 schoenebeck 1802 Added new client interface functions, for managing the
63     global limit of maximum voices and disk streams:
64     lscp_get_voices();
65     lscp_set_voices();
66     lscp_get_streams();
67     lscp_set_streams();
68    
69 schoenebeck 1806 Bugfix: fixed buggy behavior on different locale
70     settings (e.g. when parsing floating point numbers).
71    
72 capela 1412 0.5.5 2007-10-12 Changed client interface function, for editing
73     instrument, from:
74     lscp_edit_instrument();
75     to:
76     lscp_edit_channel_instrument();
77    
78 capela 1368 0.5.4 2007-10-02 Added new client interface function, for editing
79 schoenebeck 1365 instrument:
80     lscp_edit_instrument();
81    
82     Fixed some minor bugs in:
83     lscp_set_fxsend_midi_controller();
84     lscp_set_fxsend_level();
85    
86 capela 1031 0.5.3 2007-01-15 Added new client interface functions, for sampler
87     channel effect sends control:
88     lscp_set_fxsend_midi_controller();
89     lscp_set_fxsend_level();
90    
91     Added new field member to lscp_fxsend_info_t (level).
92    
93 capela 1019 0.5.2 2007-01-11 Added new client interface functions, for sampler
94     channel effect sends control:

97     lscp_get_fxsends();
98     lscp_list_fxsends();
99     lscp_get_fxsend_info();
100     lscp_set_fxsend_audio_channel();
101 capela 1369 and for global volume:

103     lscp_set_volume();
104    
105 capela 1031 Audio routing representation changed to integer array.
106 capela 1020
107 capela 997 0.5.1 2006-12-22 Added support for new (un)subscribable events:
108 capela 994 LSCP_EVENT_AUDIO_OUTPUT_DEVICE_COUNT,
109     LSCP_EVENT_AUDIO_OUTPUT_DEVICE_INFO,

116 schoenebeck 1802
117 capela 994 Updated examples.
118 capela 983
119 capela 975 0.5.0 2006-12-17 MIDI instrument mapping, second round, according to
120     LSCP 1.2 draft document as of December 15, 2006.
121    
122     New client interface functions:
123     lscp_set_channel_midi_map();
124     lscp_add_midi_instrument_map();
125     lscp_remove_midi_instrument_map();
126     lscp_get_midi_instrument_maps();
127     lscp_list_midi_instrument_maps();
128     lscp_get_midi_instrument_map_name();
129     lscp_set_midi_instrument_map_name();
130    
131    
132 capela 965 0.4.2 2006-12-04 MIDI instrument mapping fixed, previously missing
133 capela 963 the regular ON_DEMAND load mode.
134    
135     Server error reporting is now effective; all server
136     numerical error and warning codes are added to 100,
137     thus giving a proper non-zero lscp_client_get_errno()
138     return value.
139    
140 capela 948 0.4.1 2006-11-28 Fixed the flush timeout operation to be issued only
141     once, avoiding recurrent client failure after receive
142     timeout.
143    
144     Support for very long command result sets have been
145     introduced, with the downside of strictly obeying
146     the LSCP draft.
147    
148     list_midi_instruments() is now being implemented.
149    
150     LGPL text is now back in COPYING.
151    
152 capela 946 0.4.0 2006-11-27 As of the LSCP 1.2 working draft document, added
153     some missing client interface functions:
154     lscp_get_total_voice_count();
155     lscp_get_total_voice_count_max();
156     and for the new MIDI instrumenbt mapping features:
157     lscp_map_midi_instrument();
158     lscp_unmap_midi_instrument();
159     lscp_get_midi_instruments();
160     lscp_get_midi_instrument_info();
161     lscp_clear_midi_instruments();
162    
163    
164 capela 921 0.3.4 2006-09-24 GPL address update.
165    
166 capela 869 0.3.3 2006-06-01 Fixed some compilation warnings due to suspicious type
167     casting and unsused header macros.
168    
169     Changed deprecated copyright attribute to license
170     and added ldconfig to post-(un)install steps
171     to liblscp.spec (RPM).
172    
173 capela 764 0.3.2 2005-08-29 Fixed missing initialization bug on lscp_channel_info_t
174 capela 749 new struct fields (mute/solo).
175    
176     Include debian files into distribution.
177    
178 capela 754 Renamed configure.in to newer configure.ac.
179    
180 capela 735 0.3.1 2005-08-16 [bug #21] Fixed automake support for separate build
181 capela 712 directory.
182 capela 749
183 capela 735 Added support to sampler channel MUTE/SOLO states:
184     lscp_set_channel_mute();
185     lscp_set_channel_solo();
186     with corresponding new lscp_channel_info_t fields.
187 capela 712
188 capela 626 0.3.0 2005-06-10 [bug #11] Timeout flush idiosyncrasy is now a feature;
189 capela 623 this just tries to flush the receive buffer whenever
190     any previous transaction has failed due to a timeout.
191    
192 capela 626 Fixed an off-by-one timeout quirk, that has been a real
193     showstopper on Mac OS X at least, which is incidental
194     to qsampler's default timeout setting of 1000 msecs,
195     giving up systematically on select() due to "Invalid
196     argument" (EINVAL).
197    
198 capela 946
199 capela 562 0.2.8 2005-05-22 More LSCP command syntax changes, particularly on the
200     event subscription ones: the LSCP_EVENT_CHANNELS event
201     definition were renamed to LSCP_EVENT_CHANNEL_COUNT,
202 capela 564 as to be more meaningful. Added support for the newest
203     LSCP command: GET SERVER INFO; lscp_get_server_info().
204 capela 562
205 schoenebeck 1802 0.2.8 2005-05-08 [bug #9] Fixed for a LSCP command syntax convention
206     consistency, regarding the enumeration of available
207     sampler engines, Audio and MIDI drivers; this has
208 capela 523 affected the signature of the following functions:
209     lscp_get_available_engines();
210     lscp_get_available_audio_drivers();
211     lscp_get_available_midi_drivers();
212     which are now returning an integer count of engines
213 schoenebeck 1802 and drivers, respectively, while the following
214 capela 523 functions are now being introduced:
215     lscp_list_available_engines();
216     lscp_list_available_audio_drivers();
217     lscp_list_available_midi_drivers();
218     taking on the previous functionality, returning
219     a comma separated list of names.
220    
221 capela 445 0.2.7 2005-03-10 Mini bitsy regression; a severe crash (segfault)
222 capela 435 was fixed on the device configuration functions:
223     lscp_set_audio_device_param();
224     lscp_set_midi_device_param();
225     lscp_set_audio_channel_param();
226     lscp_set_midi_port_param();
227 capela 419
228 capela 415 0.2.6 2005-03-01 Fixed nasty off-by-one bug on internal helpers.
229    
230 capela 380 0.2.5 2005-02-14 Added support for the new INSTRUMENT_NAME field
231 capela 378 of GET CHANNEL INFO command.
232    
233 capela 278 0.2.4 2004-10-11 Fixed lscp_set_channel_midi_channel() again, MIDI
234     channels should be given in the range 0-15, and omni
235     mode with the LSCP_MIDI_CHANNEL_ALL symbol (16).
236 capela 415
237 capela 279 Fixed lscp_get_channel_info() to parse MIDI omni
238     (ALL) channels mode.
239 capela 278
240 capela 257 0.2.3 2004-09-28 Fixed lscp_set_channel_midi_channel() where MIDI
241     channels should be given in the range 1-16, and
242     omni mode with the new LSCP_MIDI_CHANNEL_ALL
243     symbol (0).
244 capela 415
245 capela 253 Rearrangement on main command requester executive.
246    
247 capela 213 0.2.2 2004-07-29 In sync with LSCP document draf (v.12).
248    
249     New functions added: lscp_client_get_events() and
250     lscp_reset_sampler().
251    
252     Added support for generating Debian packages;
253 schoenebeck 199 renamed pkg-config lib name 'liblscp' -> 'lscp' as
254     it's common practice to omit the 'lib' prefix.
255    
256 capela 194 0.2.1 2004-07-09 Potential cripling defects habve been fixed.
257 capela 187
258 capela 178 0.2.0 2004-07-06 New LSCP extension draft (v.11) initial support.
259 capela 103 (still a work in progress...)
260    
261 capela 946
262 capela 103 0.1.9 2004-05-18 More fixes for MSVC++ example build.
263    
264     0.1.8 2004-05-17 Fix for MSVC++ example build; snprintf replaced by
265     buffer overflow friendlier sprintf.
266    
267     0.1.7 2004-05-10 Missing version.h now included on install; WIN32 is
268     only now conditionally defined.
269    
270     0.1.6 2004-05-04 WIN32 build support; LPGL disclaimer consistency;
271     versioning functions introduced.
272    
273     0.1.5 2004-04-26 Server stuff moved into examples.
274    
275     0.1.4 2004-04-24 Initial auto/libtool preparation.
