FILE REMOVED
Simplify internals and rewrite file header parsing code: - remove -M, -t, -w, -C, -x flags that don't make sense anymore - make "-j off" the default (sndiod already does the job) - don't limit the number of played/recorded files. - add support for floating-point encoded files. - add support for apple .aiff and sun/next .au files

Don't spin if accept() fails because it is out of file descriptors, instead set a flag that skips the listening socket from the poll() event loop. The flag is cleared whenever a file descriptor is closed allowing accept() to be retried. Explained by deraadt@

Simplify and improve the way options are parsed and remove ~300 lines of code that becomes unused. Few command line arguments changes are required though: - stream definitions (-ios) now must follow devices definitions they are attached to (-fMn) - the -n option is now a special "loopback" device and is thus used like -f, eg it must precede streams - in midicat, midi thru boxes are not created automatically anymore, the new "-M" option must be used for that - channel numbers (-Cc options) correspond always to channel numbers of the hardware. - the -u option isn't needed anymore - increase the log verbosity so user errors are logged without using -d tested by many, help from jmc

aucat (server): - make the ``-m mode'' option per subdevice, allowing subdevices to be play-only or rec-only even if the server is full-duplex - add ``monitoring'' mode (with ``-m mon''). This is a record-only stream from which played streams can be recorded (kind of ``record what you hear''). - allow MIDI devices to be subscribed to the controlling MIDI port of the server, ie what midicat does (with -f option), but using the -q option. - add flow control to the protocol, and serialize clock ticks (sio_onmove() calls) and data chunks. This should fix certain full-duplex programs, broken with ``magic'' block/buffer size combinations. - enable 3 block latency which is the minimum theoretical. Make -z and -b options correspond to device parameters. - make sio_getcap(3) the same for aucat and sun backends, ie return whatever is supported (``everything'' in the aucat case, since everything is actulally supported). aucat (player): - enable ``-m mode'' option to select between monitoring and recording when ``-o file'' is used. - plug MIDI code to non-server codepath. The MIDI control device is specified with the ``-q device'' option, as in server mode. - impliment lseek()'ing within files (controlled through MIDI). Necessary to use aucat with a MIDI sequencer. midicat (thrubox): - rename ``-f'' flag to ``-q'', so it has the same name as in aucat (-f is still working) ok jakemsr@, tweaks from jmc@

Add traces to help tracking subtle timing bugs often causing underuns and overruns; such bugs are hard to debug with ktrace or a debugger. They are also handy to debug or monitor code using aucat. To enable traces, compile aucat with ``make DEBUG=-DDEBUG'' and use the -d option multiple times. ok jakemsr

Currently midi capable programs can control midi hardware, but cannot cooperate with other programs. The aim of this change is to allow any program to send midi data to other programs as they were midi hardware. For instance, this change should solve the longstanding problem of using a midi sequencer with software synthesizers. More precisely: - new midicat(1) utility (actually hardlink to aucat(1)). it creates software midi thru boxes, allowing programs to send midi messages to other programs as they were midi(4) hardware. - new midi api in libsndio (see mio_open(3)), to access midi(4) devices and midicat(1) sockets in a uniform way. - new device naming scheme <service>:<unit>[.<option>], common to audio and midi. - new sndio(7) manual describing concepts and naming The current audio device naming still works, but people having scripts or configuration files containing device names could read the sndio(7) man page and slowly start updating device names. discussed with jakemsr@ and deraadt@, help form jmc@

make the code "more correct": add reference counters to aproc structures so we can keep a pointer to the device. Beside some simplifications, this allows to easily handle the situation where the audio device desappears. No change in the behaviour.

add minimal server capability to aucat(1). When started in server mode, it listens on an unix socket and mixes/demultiplexes any number of full-duplex streams, doing necessary format conversions and resampling on the fly. programs can use the new libsa(3) library to play and record audio. The library provides a very simple API to connect to the audio server; if aucat(1) isn't running, it uses the audio(4) driver transparently instead.

move all device related stuff from aucat.c to a new dev.c file. The new dev_xxx() routines expose a "high level" self-contained interface to the device. At initialization, the device is opened and two chains of aproc structures are created: * a playback chain that exposes a (initially) empty mix aproc to which the rest of the code can attach new streams to be played * record chain that exposes a (initially) empty sub aproc to which the rest of the code can attach new stream to to record The rest of the code, has just to use dev_attach() routine to attach streams. While we're at it, add a ``devops'' structure containing pointers to the device-specific routines. This will allow later to add support for other type of device than the Sun API. Also, write the .wav headers in file_del(), so put all header related data in the file strucuture. This allows to close() the file, as soon as wpipe_xxx() aproc terminates. This will be useful for the server, because it will need to close() descripts of closed connections immediately. add mix_pushzero() routine to fill the mixer with silence. It will be used to avoid the mixer to underrun when there are no input streams. Since we always have at least one input stream there's no behaviour change. ok jakemsr
