[nas] NAS Version 1.7 (stable) is released!

[Jon Trulson]

 	It can be found at the usual location:

 	or the mirror at:

 	The only change from the 1.6g pre-release is a little build fix 
for Cygwin systems.  Both server and clients work fine under Cygwin (as of 
11/11/2004 anyways :).

 	Thanks to all of those who sent in patches and tested on various 
platforms.  NAS has definitely benefited because of it :)

 	The following is the HISTORY file section detailing the changes 
from 1.6 (stable) to 1.7 (stable).


11/14/2004 1.7 (stable)

         - 1.7 release :)

         - fixed config/Imakefile so 'configure' command would work
           under cygwin.  Tested clients/server under cygwin.

         10/06/2004

         - 1.7 release candidate

         - corrected a possible race condition in auvoxware that could
           cause the server to hang under certain conditions.  I do not
           know why I haven't seen this problem before, but I could
           recreate it easily by killing auplay while playing a long
           tune.

           If the system restarts syscalls after a signal handler has
           run, a situation could arise where the previous timer was
           never disabled.  This could cause a previous ioctl(DSP_SYNC)
           called from setSampleRate() to be constantly interrupted and
           restarted, causing an apparent hang.

           Now we just turn off the timer as the first thing in
           setSampleRate() so DSP_SYNC can actually finish.

           We also turn off the timer when openDevice is called, so the
           'wait for device to become available' code can work too.

         - Patch from Tobias Diedrich that allows mixer init to
           fail in the voxware server.

           Quote:

           With this patch "aoss nasd" works, without it would fail
           (aoss is the alsa oss wrapper script, which simply preloads
           libaoss.so, a wrapper library similar to libaudiooss).

           Combining this with the alsa dmix feature should allow nas
           to coexist with other daemons like artsd.

           See http://radscan.com/nas/nas-ml/msg01121.html for more
           details.

         - redid the FAQ in an attempt to make it more useful.  I'll
           try to keep it up to date.

         - updated libtool due to a problem(s) reported by Steve
           McIntyre.

         08/20/2004

         - clear CFLAGS before building config/config.h

         - emit the release string to the log and stdout when
           verbose is enabled.

         - if '-V' specified, emit release string and stdout and exit.

         - add a limit of 5 retries on failure to open input device.

         - barring major problems, this is a release candidate.

         06/20/2004

         - add autoconf/configure support for config/. Now, during the
           'includes' phase of the nas build, configure will try to
           figure out some things about your system and build a
           config.h file that the rest of nas can use.   Prompted by
           John Wehle's patch below.

           NOTE: you still build nas like always with the imake
           facility.  configure in this case is only concerned with
           locating various header files, functions, and the like.

         - added FreeBSD 5.x patches from John Wehle correcting
           malloc.h/stdlib.h use and other issues.

         - remove ioctl(devAudio, AUDIO_DRAIN, 0) call from
           disableProcessFlow() in dda/sun/ausuni.c that seems to cause
           problems (server hangs) with certain sun audio
           hardware/kernel drivers.

         - applied patch from James Lee correcting a coredump in
           audemo.

         - corrected problem with dia/auprocess.c that caused SIGFPE's
           in nasd when an element with a samplerate of 0 was
           processed. Thanks to Tobias Diedrich for a test case.

         - removed some pre-R5 cruft from lib/audio/ConnSvr.c that
           caused build problems on some solaris systems.

         02/14/2004

         - Fixed up some Cygwin issues... All of the clients and the
           server seem to compile and work fine now.  I tested both
           local and remote, to and from unix and cygwin.

         - Added patch from Steve McIntyre, adding a new '-config'
           option to nasd.  This allows you to start nasd with
           alternate configuration files rather than the default of
           /etc/nas/nasd.conf.  Useful if you have multiple sound
           devices.

         - Added 64bit fixes from Per Oyvind Karlsen

         12/31/2003

         - corrected a coredump with the clients in 1.6a when using a
           non-zero display number. GetAuthorization() was a bit
           confused about the order of it's arguements...

         12/24/2003

         - preparing a long overdue development release

         - ANSI'ification of libaudio.

           There seemed to be some confusion with the order of
           arguments to the AuSoundRecordToFile*() functions.

           The function declarations were made to match the prototype
           definition and the man page.

         - Modified Scott Presnell's patch to not enable BSD44SOCKETS
           on Linux or SVR4 systems. There are some structure members
           used that are not present on these (and perhaps other)
           systems.

           If you run into compilarion problems with ConnSvr.c relating
           to invalid structure members, look at the define of
           BSD44SOCKETS in Imakefile and correct for your system as
           needed.  Oh, send me the patch as well? :)

         - auvoxware

           - added some more useful debugging info.  If you get the old
             'cannot create audio block connection info" try running
             nasd with '-v -d 99' and see what the real error is.

           - certain ioctl() requests are no longer fatal (like
             SOUND_MIXER_WRITE_RECSRC and SOUND_MIXER_READ_RECSRC).
             Recording may not work properly if these fail though.

         9/14/2003

         - added patch from Marty Leisner cleaning up a couple of error
           messages in server/os/connection.c

         3/15/2003

 	- added a patch to the contrib section by Laurent Vivier - this
           patch adds NAS support to the esound daemon on AIX systems.
           Should be reasonably portable to other platforms as well.

           Rumor has it that the Ximian folks are adding this support
           officially into esound.

         3/15/03

 	- set timer in auvoxware.c to trigger when 50% of the samples
           are predicted to be consumed... This hopefully will help
           with underruns on some systems/OS's...  I'm not sure why
           this is happening on those systems (it's not happened on any
           of the systems I've used NAS on), so this should probably
           be considered a harmless workaround.

         3/4/03

 	- Patch from Scott Presnell to set BSD44SOCKETS properly for
           libaudio.

         12/11/2002

 	- patch from Steve McIntyre correcting a typo in Xtutil.h
