1999-02-20  Yo Ric Dude  <[e-mail]>

	* README, TIPS, TODO: updates
	* configure.in: call it 0.2.8. [and there was much rejoicing...]

1999-02-16  Yo Ric Dude  <[e-mail]>


	* esd-server.h, esd.c, proto.c: added forced standby tracker for
	greater accuracy in tracking forced standby vs. autostandby modes
	* clients.c: autostandby/standby cpu buglet
	* esd.h, proto.c, esdmgr.c: added ability to get server mode,
	e.g. standby, autostandby, running, etc.
	* many other modules: -Wall clean up

	* players.c, proto.c, samples.c: gracefully handle error
 	conditions from ESD_READ_*, i.e. check return values.

Mon Feb 15 18:19:31 EST 1999 Mandrake <[e-mail]>
	* esdlib.c: boy am I getting tired of reading the
	"cannot connect to esound server" error message whenever I don't
	have esd running from that file.  there needs to be a better
	way to dump out this error.  maybe some sort of rotatable message
	file?  who knows?  but not like that.

1999-02-14  Yo Ric Dude  <[e-mail]>

	* clients.c, esd.c: less brutal audio flushing algorithm.

1999-02-13  Yo Ric Dude  <[e-mail]>
	
	* esdfile.c, esdlib.c: added and commented out diagnostic code. 
	* esd-server.h, esd.c, players.c, proto.c, samples.c, players.c:
 	add flag to force sample deletion, and force sample deletion only
 	when we shut down the server
	* samples.c, players.c: check for addition of NULL
 	samples/players.
	* players.c: helps if you put the recorder stream's, writeable
	fd_set mask in the proper place within the select call - thx. Chutt

1999-02-10  Yo Ric Dude  <[e-mail]>

	* clients.c, esd.c, esdlib.c: only check for more data if the
	stream isn't a monitor stream, as there's nothing to read anyway.
	correct condition on esd_autostandby_secs for pausing. use the
	host representation of the port number instead of network order.

Fri Feb  5 14:28:17 PST 1999 Manish Singh <[e-mail]>

	* esd-config.in: erk. NEVER include @CFLAGS@ or @LDFLAGS@ in these
	scripts. They should not be propagated to client packages

1999-02-03  Yo Ric Dude  <[e-mail]>

	* esd.c: yet another CPU usage fix, courtesy of Chutt

1999-02-01  Elliot Lee  <[e-mail]>

	* Revert session management changes until further discussion.

Mon Feb  1 01:24:43 PST 1999 Manish Singh <[e-mail]>

	* esddsp.c: stupid interim hack for SNDCTL_DSP_GETOSPACE so x11amp 0.9a
	works properly

	* esddsp.in: -m flag to enable mixer support

1999-01-31  Yo Ric Dude  <[e-mail]>

	* LICENSE, COPYING.LIB: Make some effort at license term disclosure.

1999-01-30  Yo Ric Dude  <[e-mail]>

	* proto.c: corrected stream play/record/monitor protocol data lengths

1999-01-28  Felix Bellaby <[e-mail]>

	* session.c: implements session management protocol to avoid race
	conditions under gnome and allow for respawning.
	* Makefile.am, esd-config, config.in: add in SM checks.
	* esd.c (main): add SM argument passing, setup and ICE polling.
	* clients.c (wait_clients_and_data): add ICE to blocking select.
	
1999-01-26  Yo Ric Dude  <[e-mail]>

	* clients.c: fixed recently broken autosuspend feature

	* esd-server.h, esd.c, players.c: move recorder_write guts to a
	separate function, to be used by monitors, and filters.

Mon Jan 25 03:16:30 PST 1999 Manish Singh <[e-mail]>

	* esddsp.c: added a /dev/mixer wrapper. Set ESDDSP_MIXER=1 to
	for all /dev/mixer access to be trapped. It will save and load
	the mixer settings in ~/.esddsp.{name}.

1999-01-25  Yo Ric Dude  <[e-mail]>

	* mix.c, proto.c: volume control wired into the mix functions.

1999-01-24  Yo Ric Dude  <[e-mail]>

	* filter.c, players.c: fix filters to work with the translation
 	function pointers.

	* esdfilt.c: add some processing (double or halve the audio
 	signal) so we can tell if the filter is doing anything useful.

	* clients.c, esd-server.h, esdlib.c, players.c, stamp-h.in:
 	factored into a function the setsockopt calls for setting the
 	socket options for the socket buffer sizes in the court of king
 	caracticus, which was just passing by...

1999-01-24  bertrand <[e-mail]>

	* configure.in (audiofile check): Fixed a small typo

1999-01-23  Yo Ric Dude  <[e-mail]>

	* Makefile.am, esound.spec.in: updated web site, and added an rpm
	target to the makefile. "make rpm" and it should go do it's thing.

1999-01-14  Yo Ric Dude  <[e-mail]>

	* players.c: fix the recorder_write and monitor_write function to
 	use translate function.
 	
	* clients.c: fixes to the pause vs. sleep issue. select()s forever
 	if nothing to do, i.e. not recording and no samples playing.
  	
	* esd-server.h, mix.c, esd.c, filter.c, proto.c: translate
 	function pointers sketched out.  added a mixer engine debug
 	switch. filters, recorders and monitors are most likely horribly
 	broken for now.
 	
	* README, TODO: cleanups, updates, typos

Thu Jan 14 22:52:02 PST 1999 Manish Singh <[e-mail]>

	* esd.c: corrected -d help text

	* esdctl.c: 0 is a perfectly valid argument for volumes, so don't
	filter it out

	* esddsp.in: libdl isn't everywhere, don't specify it (libtool
	deps will take care of that)

	* Makefile.am
	* configure.in: check for libdl

	* acinclude.m4
	* ltconfig
	* ltmain.sh: libtool 1.2d for linux shared library deps

1999-01-13  Yo Ric Dude  <[e-mail]>

	* esd-server.h, esd.c, mix.c, players.c, samples.c: first take at
 	using function pointers for the mix functions.  probably breaks
 	filters, and who knows what else.  NOTE: work in progress, beware!

1999-01-10  Yo Ric Dude  <[e-mail]>

	* esddsp.in: corrected format of LD_PRELOAD entries, and added
	LD_PRELOAD_PATH to make things a bit cleaner.  Should correct the
	"error loading shared libs: symbol dlsym not found" problems

1998-12-30  Yo Ric Dude  <[e-mail]>

	* esdmgr.c, proto.c: workaround for zero additional data protocol
	handlers.  just require an int of data for now. fix noted in source. 

	* audio.c, audio_alsa.c, audio_oss.c, audio_solaris.c, esd.c,
 	esd.h: added -d DEVICE option - use an alternate audio device.
  	This sets esd_audio_device (const char *) which can be used by the
 	platform specific esd_audio_open() functions.  audio_oss updated,
 	audio_solaris updated but not tested.  other updates requested.

	* esd-server.h, esd.c, samples.c: actually reset *everything* in
	the daemon on a SIGHUP

1998-12-29  Yo Ric Dude  <[e-mail]>

	* clients.c, esd-server.h, esd.c, proto.c, samples.c: option to
	autosuspend after a number of seconds of audio inactivity.
	"esd -as SECS" to set timeout to SECS seconds, SECS > 0.
	* esd.c, clients.c: call esd_audio_pause() only if select has
 	returned no clients ready, and no samples are playing.  other
	miscellaneous tweaks to the when-to-sleep algorithm...
	* players.c: add a variable so we know if we're playing samples
	* all other server files: editorial changes, prettier for printing 
	
1998-12-27  Yo Ric Dude  <[e-mail]>

	* proto.c: missed one code path for setting is_ok...
	* clients.c, esd-server.h, esd.c, esd.h, esdloop.c, esdsample.c, 
	filter.c, mix.c, players.c, proto.c: moved some prototypes to
	more logical locations, and general -ansi -Wall -pedantic stuff.
	* esd.c: added -h option for usage.

1998-12-22  Yo Ric Dude  <[e-mail]>

	* audio_alsa.c, clients.c: from bibek, more alsa patches and a
 	slightly more sane "can i pause" algorithm.

Mon Dec 21 21:44:44 EST 1998 Mandrake <[e-mail]>

	* esdlib.c - fixed some warnings.

1998-12-21  Yo Ric Dude  <[e-mail]>

	* clients.c, esd-server.h, esd.h, players.c, proto.c, samples.c:
 	Cleaned out the protocol handling.  Basically, there's now a table
 	of protocol handlers and how much data they each require.  Each
 	client has a buffer to hold the extra data for the current
 	protocol handler.  poll_client_requests() reads data one chunk at
 	a time, until it gets everything it needs for that request.  The
 	handler then gets its data directly from the buffer, instead of
 	messing around with all this state transition stuff.
	* configure.in: setting bin_SCRIPTS to include esd-config should
 	set the execute flag on the script when installed.
	* esdlib.c: this needs esd.h, not esd-server.h.
	* mix.c, esd-server.h: debugging info update.

Sat Dec 19 21:19:51 EST 1998 Mandrake <[e-mail]>
	* down to just 7 warnings compiling on my system now -- everything
	works pretty well now, I think, too.  still a few 8bit sound problems
	with samples, which I may look into later this weekend.

Sat Dec 19 14:02:41 EST 1998 Mandrake <[e-mail]>
	* cleaned up warnings and a little bit of code here and there.
	(when you've got as many compiler warning flags turned on as I do
	this code was starting to look a bit horrendous compiling)  I'm
	not 100% done, but this is a good start.

Thu Dec 10 20:55:43 PST 1998 Manish Singh <[e-mail]>

	* esd.c: use nanosleep if we have it, it seems to work better
	(at least for me)

Tue Dec  8 23:32:52 PST 1998 Manish Singh <[e-mail]>

	* Makefile.am
	* configure.in
	* esd-config.in: correctly handle AUDIOFILE_* vars

	* Makefile.am
	* configure.in
	* esddsp.c: use dlsym instead of __func. Now works with glibc 2.1
	and FreeBSD (maybe others? testers wanted)

1998-12-08  Yo Ric Dude  <[e-mail]>

	* acconfig.h, configure.in, esd-server.h: use autoconf to turn
 	on/off insanely verbose diagnostic information

	* clients.c: improved timeout for select algorithm - if we're
 	recording, return immediately, otherwise timeout after 1/2 an
 	ESD_BUF_SIZE amount of time.

	* esd.c: just use select instead of this nanosleep stuff.

	* samples.c, players.c: fixed problems with looping samples and a
 	pointer assignment warning

Wed Dec  2 11:27:20 EST 1998 The Rasterman  <[e-mail]>

	* clients.c, esd.c, esdlib.c, players.c: Added setsockopt to set the
	socket bufferign options to the minimum needed to keep esd fed with
	audio data to also minimize "lag" with streams. Seems to work fine.

1998-11-30  Jeff Garzik  <[e-mail]>

	* configure.in:
	Don't dump environment to stdout.  Every user doesn't need to
	see this data, just a few hackers.

1998-11-28  Yo Ric Dude  <[e-mail]>

	* players.c, samples.c: swap 16 bit audio data if the server and
	client are on differring endian machines. - not tested! =)
	
	* configure.in: --enable-esdplay has been converted to
 	--with-libaudiofile. some files of the esound source WILL NOT
 	currently compile unless libaudiofile is installed.  with the
 	inclusion of the audio file handling routines, libaudiofile is now
 	a requirement for esound.  Anyone wishing to patch the source so
 	it will still compile without libaudiofile is welcome to.

	* esd.h, esdfile.c, esdplay.c, esdsample.c: add a string to
	differentiate between sample files cached by different programs with
	the same name.

	* Makefile.am, esdfile.c, esd.h: added convenient audiofile
	wrappers for playing and caching audio file data. 
	* esd.h, esdlib.c: const clean up.
	* esdmgr.c: added name to print info functions.
	* esdplay.c, esdsample.c: updated to use audiofile wrappers.
	NOTE: this means that the AUDIOFILE library is now REQUIRED for
	proper compilation of esound.  configure.in will be updated soon.
	
Mon Nov 23 06:34:43 PST 1998 Manish Singh <[e-mail]>

	* configure.in: allow manual enable/disabling of alsa support

1998-10-21 Bertrand Guiheneuf <[e-mail]>

        * use the audiofile.m4 macro to detect libaudiofile

1998-11-09  Yo Ric Dude  <[e-mail]>

	* clients.c, esdlib.c, filter.c, mix.c, players.c, proto.c
	samples.c: use the freshly updated debugging macros

	* esd-server.h, esd.h, esdctl.c, esdlib.c, esdmgr.c, mix.c,
	players.c, proto.c, samples.c: initial support for setting stereo
	panning of streams and samples, just need to update mix.c to do
	the scaling...

Sat Nov  7 05:28:03 PST 1998 Manish Singh <[e-mail]>

	* esddsp.c: Hmmph. The ES1370 driver blocks on open unless
	O_NONBLOCK is set explictly. So now we strcmp always, and
