Version 1.5 12/26/2001

## 12/1/2001

- Corrected manpage html generation issue with the nasd.conf
  manpage via patch from Erik Inge Bolso


## 1.4.2d  11/25/2001

- implemented locking in libaudio via Xthread mutexes.  

  This is kind of a big change, but the result should be a
  threadsafe libaudio.  I used Xthreads, because then
  theoretically I shouldn't have to care about the system's
  actual thread implementation. Right?? I've tested so far on
  Linux (uses pthread_*) and Unixware 2.03 (uses thr_*).  So
  far so good.

- bumped up the libaudio rev to 2.2

## 1.4.2c  11/4/2001

- turned off streams support on SVR4 systems for libaudio.
  UNIX and TCPCONN work just fine.  The nasd server hasn't
  used streams support since the 1.3 timeframe anyway.  This
  will work around local connection issues on UnixWare and
  probably Intel Solaris as well.  

- added patches from Steve McIntyre to work around an XFree86
  issue, and prevent the HPUX server from being built on HPPA
  systems running Linux.

- add change to AuServerName() in libaudio to default to
  'tcp/localhost:8000' if neither AUDIOSERVER or DISPLAY are
  set as per a suggestion by Erik Inge Bolso.

## 1.4.2b  10/6/2001

- Added patches from Peter Berg Larsen to the Sun server that
  adds support for $AUDIODEV on Sun Ray platforms.

- Added patches from Peter Berg Larsen that corrects some
  issues dealing with dead clients, and improper server resets
  when persistent flows are still active.  Also, some
  uninitialized variables are now properly initialized.

## 1.4.2a  4/21/2001

- patch from Steve McIntyre to resolve man page issues, and
  add a libm dependancy to libaudio for linux platforms.

- patches from Philippe Jouguet

new options in nasd.conf for the voxware server:
- add 'mixer' device option to secify the mixer.
- add 'forcerate' option to force the sample rate
  to the current rate at all times
- add 'autoOpen' option to specify whether the audio
  devices are opened at init time.
- add 'readwrite' option to specify whether devices
  are opened read/write (default) or
  readonly/writeonly for the input and output devices,
  respectivly.


- added patch from Nick Ing-Simmons to pass the correct port
  offset when starting nasd within libaudio (if START_SERVER
  is defined at build time).

- always output verbose/debugging info to stderr if debugging
          is enabled (even if you normally use syslog).  stderr is not
          closed when debugging is turned on.


Version 1.4.2 4/8/2001:

        ## 1.4.1b 3/9/2001

- added patch from Paul Fox allowing auctl to set gains based
in an increment

- added a patch to lib/audio/wave.c from Philippe Jouguet that
          corrects an infinite loop that can occur when auplay is fed
          a corrupted wave file.

- added patches to auplay from Paul Fox.  auplay will now stop
          the flow when a signal is caught.  Also a new option '-l'
          allows auplay to play filenames specified on stdin.

- set libaudio's SO revision to 2.1 from 1.4 to avoid
  confusion with older apps built when the older libaudio
          was at 2.0 (debian).

## 1.4.1a 12/10/2000

- autool - fixed -volume option

- added cast from a patch by Sun Ireland for their OpenOffice
(StarOffice) project.

- fixed libaudio to start up 'nasd' instead of 'au' when 
START_SERVER is defined.

- applied Erik Inge Bolso's patch for properly opening 2
          channels instead of 3 for stereo output devices.

- added HPUX 10.20.x patches from Klaus Dittrich

- fixed problem in lib/audio/Alibint.c regarding ambiguous
          casts with void pointers in the buffer padding code, and to
          make it more portable with other operating systems/compilers
          (HPUX 10.20, UW7).

- lib/audio/soundlib.c - fixed cases where a client (like
          auplay) would hang if the element Import size matched the
          complete datasize of a flow.  An EOF would never be sent.
          Thanks to Shigeharu Takeno for providing a reproducible test
          case.

- added Unixware 7.1 patches from Robert Roselius.

 - added patch to sun/ausuni.c from John Wehle correcting a
          problem on some solaris machines that don't allow sbpro
          devices to be open for both reading and writing.

- add patches from Steve McIntyre for creating sticky socket
          directories, and to close stdin, stdout, and stderr.



Version 1.4.1 9/4/2000:

- this release is really only neccessary if you are using the
          NAS server on a Sun, and have frequent dropouts.  

- fix to the sun server from Charles Levert correcting a Sun
          problem with 'late SIGPOLLS'.

- minor documentation fixes - new mailing list archive
          location, etc.

Version 1.4 2/27/2000:

- Release of 1.4

- Removes USE_BSD* dependancies on Linux builds.  

## 1.3e 02/12/2000:

- This is a pre-release 1.4 candidate.

- corrected a problem in the voxware server where when
ReleaseDevice was enabled, the device would be held
open when nasd was first started until the first
connection was made.

- added config/NetAudio.def to set various configurables like
NasConfigSearchPath.

- changed documentation regarding the new location of the web 
site (http://radscan.com/nas.html)

## 1.3d 01/05/2000:

- corrected some build problems on Sparc Solaris 2.6 with native 
compiler/X11 env

- corrected build problems on native Unixware compiler and X11R5
Note, to get this to work, you need 3 corrected
/usr/X/lib/config/ files from me...

- integrated config handling in all servers, based on a 
lex/yacc parser from Stephen Hocking that was in the 
voxware server.

- config file is /etc/nas/nasd.conf
an example config file (/etc/nas/nasd.conf.eg) 
is installed.
- parser errors are a bit more informative ;-)
- no more parser in voxware server... moved into dia/
for general purpose use.
- each server now has a config.c and config.h file that 
provides the ddaSetConfig() functionality required
of each server by dia/.  In the SGI case, 
it's just a stub. ddaSetConfig() ignores options
it doesn't understand (required behavior).
- server cmdline options '-v' (verbose) and '-d <num>'
(debug messages) added.  These override 
nasd.conf settings.
- hooks added to all servers in config.c - ddaProcessArg() 
and ddaUseMsg() for integrated arg handling.


- voxware server:
- release device functionality now controlled by
nasd.conf
- mixer init policy now controlled by nasd.conf

- sun server:
- added integrated sun (ausuni) module (now built by 
default) into the distribution.  
- release device functionality now controlled by
nasd.conf

- hpux server:
- added device release (ReleaseDevice) capability to hpux
server.  All servers except for sgi now
support this functionality.
- fixed sample rate change problem in hpux server
- separated hardware init code for ReleaseDevice 
functionality
- added new option in nasd.conf to select either the
EXT (external - headphones/speakers) or INT
(internal speaker) output device by default

- renamed generated server binary from au* to nasd for all
servers
- man pages updated (auserver.man and 
AUVoxConfig.manrespectively).

## 1.3c 10/24/99:

- Added patches from Mark Davies for NetBSD.  

- changed BIG_ENDIAN ->NAS_BIG_ENDIAN and LITTLE_ENDIAN to
NAS_LITTLE_ENDIAN per Mark's suggestion globally

- Added global NasConfig struct for configurables global to all 
servers.

- More prep work for unified arg/config handling

- Some bug fixed related to the 'mondo' patch.

- Replacement of PRMSG() macros with a varargs logging function:
osLogMsg(...).  If your working on a server and want to
use these, #include "aulog.h" (in 1.3c+) and go for it.

- I've added a NasConfig.h file to config/ that defines (or will)
a few things (like whether you want to use syslog,
etc).  Initially you will need to tweak this manually 
for your site... 

- Changes made to the way various include files are generated
during a build... Basically any module that contains
header files needed by other modules have the
appropriate header files exported into TOPLEV/include 
during the includes phase of the build using the imake
BuildIncludes() macros.  

## 1.3b 9/4/1999:

- Addition of Steve McIntyre's Mondo patch.

## 1.3a 8/1/1999:

- First test version incorporating many patches from around
the planet, based on original 1.2p5 sources.

############################################################################
# the following is included for historical reasons, and concerns
#  changes to 1.2p5 and earlier versions. 

** 1.2 - PATCH 05 **

Server
o voxware bug fixes, configuration file, and man pages.
  (Thanks to Stephen Hocking)

o fixed some HP server compilation problems.

o fix a potential problem when reading from a client.  under
  some circumstances the read pointer could be left on
  a non-sample size boundry resulting in white noise.

o add a bit to the component use field to indicate that using
  that component will override the use of other components.  This
  bit is used on input devices when the audio hardware does not
  support recording and playing simultaneously.

o fix a problem with limiting samples on waveform devices.  if you
  used anything other than AuUnlimitedSamples, bad things would
  happen.

Library
o fixed a problem reading some wave files.

Clients
o auphone - check for the exclusive use bit.

o auscope - display the exclusive use bit.

Misc
o support library and client compilation under Windows NT with
  X11R6.1.

** 1.2 - PATCH 04 **

Server
o fixed a bug in the Sun dbri driver that caused the speaker
  to get turned off.  (Thanks to Charles Levert)

o fixed an ancient server bug that caused buffers to get
  corrupted when a flow is stopped and restarted.

Clients
o some more minor bug fixes to auscope.

** 1.2 - PATCH 03 **

Server

  Bill Sebok)

o added AuSoundRecordToDataLength() which can be used to find the
  length of data recorded when recording to memory.
  (Thanks to Jonathan Thompson)

Clients
o minor bug fix to auscope.

o audemo - cut off filename extensions from the right instead
  of the left. (Thanks to Raymond Toy)

Misc
o Updated SunOS 4.1.3 OpenWindows notes in BUILDNOTES.
  (Thanks to Curt Schroeder)

o Added notes and patch for running on a SS5 to BUILDNOTES.
  (Thanks to Mikael Pettersson and Curt Schroeder)

o Added note for building clients under AIX to BUILDNOTES.
  (Thanks to Harald Milz)

o Added note for building on DEC Alpha (OSF1 V3.2).
  (Thanks to Andrew Daviel)

** 1.2 - PATCH 02 **

Server
o caused the server to return to the lowest sampling rate when a
  flow terminates while playing multiple flows simultaneously.

o improved voxware dda driver.
  (Thanks to Stephen Hocking and Shawn M.)

o experimental HP dda driver.  (Thanks to William J. Hunter)

o add a -timeout option to the server to allow the server to
  terminate after a period of time with no clients.
  (Thanks to William L. Sebok)
  To enable this, you must build the NAS tree using the following:

  make WORLDOPTS='-k CDEBUGFLAGS="$(CDEBUGFLAGS) -DSTARTSERVER"' World

Library
o fixed a bug in the wave file reader.

o fixed a bug in the aiff file reader.

o new soundlib/sound functions AuSoundPlay(), AuSoundRecord(),
  and SoundTellFile() with man pages.  (Thanks to Yoav Eilat)

o attempt to launch an NAS server on the local host if client
          cannot initially connect to a local server.
          (Thanks to William L. Sebok)
  To enable this, you must build the NAS tree using the following:

  make WORLDOPTS='-k CDEBUGFLAGS="$(CDEBUGFLAGS) -DSTARTSERVER"' World

Clients
o add *input resources to all X clients to correct a problem
  with some window managers not giving focus.

o fixed bug in auscope when displaying actions or parameters.

o fixed typo in auscope that caused it not to work with Perl 5.

o added playRaw example client.


** 1.2 - PATCH 01 **

Server
o added output mode control (Speaker/Headphone/Line-Out) to the server
  and the Sun dda drivers. (thanks to Ian Donaldson)

o fix for multiple bundle elements in a flow. (thanks to Steven King)

o improved voxware dda driver.
  (thanks to Christian Schlichtherle and Stephen Hocking)

o the server now does a range check on the output data and
  clips correctly.  Due to the possible performance impact,
  this can be disabled by commenting out the #define
  OUTPUT_RANGE_CHECK in server/dia/auprocess.c.  ** ATTENTION
  DDA DEVELOPERS ** this fix required a change to all of the
  dda drivers.  The output minibufs must be twice as large as
  they were previously.  (thanks to Steven King)

o voxware dda driver - Fix problem (apparently from
  SoundPlayFromBucket) where tail of data was not flushed
  through card until start of next operation.  (Thanks to Paul
  F. Werkowski)

o only call dda set sample rate callback if the rate has changed.

Library
o SVR3.2 with STREAMSCONN wouldn't work with XDMCP due to a
     bug in nameserver.c.  (required XDMCP to be disabled; this
     won't affect users of stock NAS 1.2 but would affect those
     audio servers that implement XDMCP authorization checking)
  (thanks to Ian Donaldson)

o fatal errors now lookup AuErrorDB for more detail.
     (like Xlib does with XErrorDB) (thanks to Ian Donaldson)

o Implementation of user callable error catching functions:
AuSetErrorHandler()
AuSetIOErrorHandler()
  (thanks to Ian Donaldson)

o added default error handler variables so you can catch errors
  during the initial server open.  (Thanks to Richard Caley)

o added some setjmp gunkus to Xtutil.c for use by error handlers.
  (Thanks to Richard Caley)

o C++ compatibility. (Thanks to Yoav Eilat)

o New SoundSeekFile() and SoundFlushFile() functions.
  (Thanks to Yoav Eilat)

o SoundNumSamples() value is now updated in SoundWriteFile().
  (Thanks to Yoav Eilat)

Clients
o added re-written auscope.

o modified aupanel to support output mode controls.

General
o made all the Imakefiles use an explicit path for NetAudio.tmpl
  to fix possible includes of the wrong NetAudio.tmpl.

o some notes on building under SunOS 4.1.3 OpenWindows from
  Ian Donaldson.

o new API man pages from Steven King.  (Thanks!)

o made man page installation use standard InstallManPage macro.

o use AuInstallScript macro to install scripts.

o fixed some build and install problems under FreeBSD 1.1.5.1.
  (Thanks to Paul F. Werkowski)

** Release 1.2 **

General
o A few cosmetic changes.

** PATCH 02 **

Server
o fixed a bug with monitor elements not returning the correct
  data.  This caused the meters in audemo to be broken.

o patches from Steven King

    - In server/os/connections.c, EstablishNewConnections
              probably ought to check that newconn is less than
              lastfdesc before it is used in the BITSET macro (this in
              the mit X11r5 source, havent looked at r6 yet), tho
              you'd need lots and lots of connections to tickle
              this. Also in connections.c, CheckConnections should
              probably check for EINTR if select returns an error, I
              dont know if any implementation of select would actually
              EINTR for if it got a SIGPOLL or SIGALRM if the timeout
              is zero, but better safe than sorry.

            - FallbackDefineSelf exists and is only referenced in
              os/access.c. Its part of the localconn patch which
              obviously isnt handling non 386 svr4's correctly.

Library
o fixed a bug in AuSoundRecordToData().  The flow wasn't getting
  stopped when the recording was finished.

o fixed compile problem in ConnSvr.c under Dell 2.2 Xfree86-2.1.1.

o fixed compile problems under some X11R4s that don't define _Xconst.

Clients
o fixed problem with audial -recognize messing with line mode and
  gain attributes without checking to see if the device was capable.

o fixed range/clipping problem in effectsAmplitude in auedit.

General
o changed occurances of the name "NetAudio" to "Network Audio System"
          or "NAS" due to a name conflict.

o patches from Ian Donaldson

    - Solaris 2 server failed to link because of undefined
      symbol FallbackDefineSelf().

    - Shared library compilation broke completely due to
      changes in NetAudio.tmpl and because the include of
      <Library.tmpl> was moved too high up in
      lib/audio/Imakefile, and missed out on the
      DoSharedLib/DoNormalLib flags etc.

** PATCH 01 **

Server
o fixed a couple of problems with speed changes in the
  SVR4 VOXware driver.

** Release 1.2b BETA **

Library
o fixed possible bogus free in sound.c.

Clients
o fixed auwave dropping core (due to bugs in the slider widget).

General
o lots of stuff from Steven King.  See CHANGES.sk below for details.

o The file server/PATCHES.sk contains patches from Steven King to
  improve the handling of audio clipping in the server. I've
  not applied them to the standard distribution yet because
  I'm concerned about their possible performance impact.

o added some documentation about actions.

** PATCH 01 **

Server
o fixed a bug with looping flows.

Library
o fixed problem with X11R4 build.

** Release 1.2a ALPHA **

Server
o fixed a bug in ReadElement that would occasionally cause
  protocol errors during recording.

o wake up the server when there are events to send out.

o fixed a bug in readBucket() that caused noise at the end of
  a bucket.

o get rid of minibuf padding to eliminate clicks.

o optimized sample rate conversion.

o added FreeBSD/Linux VOXware driver (thanks to Amancio Hasty).

o added SVR4 VOXware driver (thanks to Stephen Hocking).

o added line mode control to Sun dbri driver.

Library
o add AuXtAppRemoveAudioHandler().

o fixed memory leaks and other problems with the bucket attribute
  cache.

o fix some nits with waveform durations.

Clients
o new auphone sample app.

o added some simple examples.

General
o much cleaning and various OS support fixes from
  Ian M. Donaldson.  See CHANGES.labtam below for details.

** Release ?.? ALPHA (Feburary 11, 1994) **

Server
o fixed a bug where the last little bit of audio data would be
  lost.

o fixed a bug in readClient where the buffer was being incorrectly
  padded, possibly resulting in static at the end of the audio data.

o fixed two track monitor elements.

o Sun driver

- fixed a bug that could cause the output to get jumbled.

- wait for audio to drain after flows finish.

- Sparc 10 dbri driver.

Library
o added API for set and get close down mode.

o added Amiga IFF/8SVX sound file support.

o close the sound file before the callback is called for
  AuSoundRecordToFile().

o make ListBuckets add to the bucket cache.

o added file format suffixes to the SoundFileInfo structure.

o added AuSetString() macro.

o fixed "strdup" bug in SoundCreate.

o re-arranged some utility routines into separate modules.

         are no longer externed in audioutil.h)

o add AuWaveFormToString() and AuStringToWaveForm().

o add AuSoundRecordToData().

o add stereo support for voc files (thanks to Steven King).

  (like those from stdin).

- add record capability.

o utilities

- various new utilities.

o new auwave sample app.

o new slider widget for volume/gain controls.

General
o re-worked the includes of NetAudio.tmpl so it will (hopefully)
  work on most platforms.

o builds under SVR3.2 (thanks to Steven King).

** Release 1.1 **

Server
o Protected malloc/free from audio signals.

o Fixed setting parameters of waveforms and buckets.

o New dia/dda interface.

o Fixed a bug where the flow was re-compiled after
  an event was requested even if that event didn't change
  the state of the flow.

o Fixed possible memory trashing in readClient.

o Sun driver

- Don't initialize output gain or internal/external speaker
  mode.

- Get rid of some 'clicks'.

- Deal with the situation when there are no physical outputs
  in a flow.  This fixes the core dumps when you record before
  having played anything.

- Fixed erroneous calling of AuProcessData() after changing
  gain values.

- Fixed various bugs in recording (how did it ever work?!)

o New SGI driver (thanks to Reiner Ernst)

Library

o auconvert
Fixed a bug with converting raw data.

General
o Solaris 2.2 support


********************************************************************************
      CHANGES.labtam
********************************************************************************

Many thanks to Ian M. Donaldson at Labtam for the following:

- Now compiles cleanly on all these without any compiler warnings
  whatsoever (well the odd one or two under X11R4).

- Solaris 2.3 on SS1000 under Sun provided Open Windows 3.2
  Server untested.  
      (We only have a SS1000 running 2.3 which has no audio device)

  Porting required because Sun changed the audio interface
  slightly in Solaris 2 versus SunOS 4.

  Clients tested reasonably.

- AIX 3.2 on a RS6000/220 under IBM provided X11R4
  No server port done.  Don't have access to any IBM audio hardware.
  Clients tested reasonably.

- SunOS 4.1.2  on a Sun IPX under MIT provided X11R5.
  (no porting required specific to this platform)
  Both clients and server tested reasonably.

- SVR4.0/486  on one of our own computers under MIT provided X11R5.
  (as a guess comparable to Dell SVR4.0 or ESIX SVR4.0)
  We used native STREAMSCONN TLI TCP/IP transport.
  No server port done.  This computer never had audio hardware.
  Clients tested reasonably.

- SVR3.2/486  on one of our own computers under MIT provided X11R4.
  This O/S uses Lachman provided TCP/IP, and we used
  STREAMSCONN TLI TCP/IP transport.
  No server port done.  This computer never had audio hardware.
  Clients tested reasonably.

  Unfortuantely every SVR3.2 system has some different
  quirk since TCP was non-standard then.   No guarantees
  it will compile better on other types.

- Bugfixes
- server had byte swapping  error that crashed playbucket(1)
  when client run from opposite endian host

- autool crashed on little endian host when volume slider was
  used when stopped (hung on big endian host)

- various signal mis-use.  Background processes from non-job
  control shells don't die when ^C hit anymore.

- "SVR4" is not a reliable symbol for use in Imakefiles; use SystemV4
  instead.  (broke audial).

- in Netaudio.tmpl, don't redefine MKDIRHIER or BINDIR by
  default as this breaks the bootstrap in subtle ways on 
  certain systems.  Audio clients now get installed in the
  same directory that X clients do rather than /usr/local/bin.

  On Solaris 2.3 with OpenWindows, this means /usr/openwin/bin,
  otherwise it usually means /usr/bin/X11.
  Similarly for header files, app-defaults and libraries.

- build will not fail on systems that don't have servers ported
  to them.  This allows the clients and libraries to be built
  on all platforms and servers on a subset.

- libaudio is built as a shared library (currently rev 2.0) on systems
  where libX11 is built shared.  In the list above that means
  Solaris 2.3, SunOS 4.1, SVR4.0.
  I used rev 1.0 for the September 93 netaudio release but changes
  between then and netaudio 1.1 looked somewhat incompatable so I bumped
  the revision number then.

- X11R4 compatability re-added in so compiliation in those 
  environments is now possible.

- STREAMSCONN support for SVR3.2 and SVR4.0 for libaudio.  
  This is a direct port from MIT X11R5 with the odd fix-tracker applied.
  NB: Not done for auscope(1).  sockets used in that case.
  (this is ok but if people want binary compatability from SVR3.2
  to SVR4 sockets won't work because SVR3.2 has no standard socket ABI)

- Better System-V and SVR4 support

- Use System-V reliable signals.  (ie: sigset(2)).  
  signal(2) is unreliable on System-V systems.
  Didn't bother with SVR4/POSIX signals; SVR3 signals work
  fine on SVR4 and are easier to understand and code.

- don't use libucb at all on SVR4.  This library is bad news
  on most SVR4 systems and should be avoided like the plague!

- Better ANSI support (SVR4 + Solaris)

- use ANSI memcpy/memset exclusively on ANSI systems instead
  of bcopy/bzero

- eliminated all SVR4.0/486 cc's reported warnings of callback
  function type declaration mismatches.  (this is the bulk
  of the changes).  Solaris 2 cc doesn't report half these things
  unfortunately.

- auscope(1) now has a '-n' flag so it can be run in background reliably.

- 'make install' now fully installs correctly.  Even app-defaults!

- 'make clean' now properly cleans

Thanks to Steven King for the following:

- building on ISC

    I had a few problems building 1.2a on my system running ISC SVR3.2r4.0
    with the imake enviroment provided by XFree86 (It looks to be more
    work than its worth to get netaudio to build with the vendor supplied
    X11R4).

    In server/dia/au.h, ISC doesnt have memmove, however bcopy and friends
    are in the normal library search path.

    In lib/audio/Alibnet.h, the omission of the #define for _AuWriteV
    resulted in link errors for all clients.

    In lib/audio/Imakefile, the SYSV_DEFINES macro causes major grief if
    one has installed XFree, I would expect this to be true for any SVR32
    that has XFree.  Also, I found it usefull to include NetAudio.tmpl
    after Library.tmp so that I could redefine things like CDEBUGFLAGS and
    such in NetAudio.tmpl

    In clients/audio/audemo/audemo.c, ISC needed sys/time.h included, I
    suspect most SYSV's will as well.

    In clients/audio/audial/audial.c, the compile breaks on the inclusion
    of sys/file.h, I think this is a ISC 4.0 specific problem.

- localconn patches

    These patches are derived from the XFree86 2.0 release.  I pretty much
    just merged the XFree patches into netaudio.  My principle interest
    was in the streams localconn code for ISC; besides greatly improving
    the performance for local clients, they allow the server to run with
    the system at run level 2, or on systems where full networking isnt
    availible (an extra $$$ option on ISC and lots of other PC sysVs).
     In addition to the ISC code, theres also support for other systems, SVR4,
    SCO, linux and net/free bsd, which may or may not be usefull depending
    on the system (ie, is anyone doing an independent SCO port?).  There
    is also alot of code for a minix and amoeba port.  I can pretty much
    guarantee that this will not work, but I left it in as it doesnt affect
    the other systems and might give a leg up to anyone attempting a minix
    or amoeba port.

- NetAudio.tmpl

    Make clients get rebuilt after libaudio.a changes.
