changelog

mpg123 是 MPEG 1.0/2.0/2.5 的实时播放软件

	  trunk/src/dct64_i486.c, trunk/src/debug.h, trunk/src/decode.c,
	  trunk/src/decode_2to1.c, trunk/src/decode_3dnow.s,
	  trunk/src/decode_4to1.c, trunk/src/decode_MMX.s,
	  trunk/src/decode_i386.c, trunk/src/decode_i486.c,
	  trunk/src/decode_i586.s, trunk/src/decode_ntom.c,
	  trunk/src/equalizer_3dnow.s, trunk/src/tabinit_MMX.s: First part
	  of boilerplating and sorting all out. Looks kinda nice now,
	  still would like to get the higway mmx stuff clear... maybe
	  Michael remembers something there.

2006-07-17 02:15  thor

	* trunk/AUTHORS: little update for MMX, unnecessary verbosity
	  about what maintaing implies

2006-07-17 01:30  thor

	* trunk/src/audio_jack.c: boilerplate and // -> /* */ as mpg123 is
	  (still) an old-compiler friendly project

2006-07-17 01:02  thor

	* trunk/src/common.c, trunk/src/control_generic.c,
	  trunk/src/httpget.c, trunk/src/layer3.c: Oh, I should compile
	  more often with strict settings: pedantic gcc complained about
	  some C89 violations I introduced. Fixed that.

2006-07-17 01:01  thor

	* trunk/configure.ac, trunk/src/audio_alsa.c,
	  trunk/src/audio_alsa09.c: Old alsa output doesn't work with any
	  sane setup using alsa today (meaning: not using the 0.5 api).
	  New doesn't work because unfinished yet. Alsa output actually is
	  available through libao. So, deactivated alsa stuff in configure
	  for now...

2006-07-17 00:06  thor

	* trunk/Makefile.am, trunk/autogen.sh, trunk/configure.ac: more
	  boilerplates

2006-07-16 23:56  thor

	* trunk/MakeLegacy.sh: boiler

2006-07-16 23:54  thor

	* trunk/scripts/debugdef.pl: public domain should be gpl
	  compatible...

2006-07-16 23:46  thor

	* mpglib/trunk, trunk/mpglib: mpglib will be something of its own,
	  taken care of later...

2006-07-16 23:39  thor

	* trunk/Makefile.win32, trunk/test.pl: niceness by a line

2006-07-16 23:38  thor

	* trunk/test.pl: boilerplate, style cleanup (could use more use,
	  though)

2006-07-16 23:37  thor

	* trunk/Makefile.win32: boilerplate

2006-07-16 23:24  thor

	* trunk/src/audio_oss.c: just a paranoid note

2006-07-10 02:23  thor

	* trunk/src/audio_libao.c: Polished the libao output a bit while
	  testing it on my linux laptop: - parsing -a driver:file for file
	  devices (well, this could be extended to a general scheme to
	  choose between different driver subsystems via -a system:file or
	  system:device:file ...) - corrected the error handling: -1 is
	  expected on error by mpg123.c - giving help message with list of
	  available drivers when invalid one is specified I verified with
	  one testfile that -a wav:file does the same as -w file. I think
	  that this is good;-) Also, I'd like to mention that it's nice to
	  measure audio subsystem overhead with comparing -t and -a null.
	  With the libao in place, I'm wondering if we still want our own
	  alsa output... let's see...

2006-07-09 17:37  thor

	* buglog/fuzzing.txt, buglog/mathias_wenzel_stress.txt,
	  trunk/src/layer3.c: next segfault by fuzzing... fixed this
	  special test case but one needs full understanding of layer3.c
	  to really get it

2006-07-06 14:00  thor

	* buglog/mathias_wenzel_stress.txt, trunk/src/common.c,
	  trunk/src/layer3.c: Fixed the mpeg2.5 verdict in common.c (we
	  have to check support for this); made parts of layer3.c more
	  robust based on an evil mp3 (see the buglog file). Most
	  important featur of this robustness could be that mpg123 doesn't
	  simply exit() in wrong sideinfo anymore but tries to continue.

2006-07-05 20:45  thor

	* trunk/TODO, trunk/src/httpget.c: Revised my bugfix for the last
	  GLSA issue after suggestion by Daniel Kobras (allow longer
	  redirection urls than request url), spent some time hacking
	  further ... and: - fixed unnoticed memory leak in redirection
	  (malloc without free for assigned pointer) - now accepting
	  non-absolute redirects; request now is always of the form GET
	  http://host/path HTTP/1.0 (non-absolute relocations are related
	  to this request) That also works flawlessly with my virtual
	  domain setup on my server used in the test. - decided that this
	  whole file is evil; we need to rewrite that properly

2006-07-04 12:41  thor

	* buglog, buglog/buglog.txt,
	  buglog/gentoo-bug133988_GLSA_200607-01.html,
	  tags/0.59r-thor6/mpg123.c, trunk/src/httpget.c: Reacted to
	  gentoo bug 133988 / GLSA 200607-01 and fixed it properly,
	  storing and using the allocated length of purl as well as
	  ensuring string termination.

2006-07-04 01:43  thor

	* trunk/src/common.c, trunk/src/layer3.c, trunk/src/layer3.h,
	  trunk/src/mpg123.c: Again reworked the gapless stuff... should
	  be more efficient now and also more aggressive by just skipping
	  decoder delay even if no info found and also adding decoder
	  delay to end (hm, where does this really make sense without
	  padding removal?). It should be more efficient now; a comparison
	  between linux-x86 binary (pentium) with and without gapless code
	  shows perhaps around 0.2% speed penalty through added code -
	  which already melts when gapless mode is actually active.
	  Generally on speed: comparison with 0.59r (linux build,
	  non-marched cflags (pentium2)) shows around 2% slower decoding
	  for svn trunk; but this is greatly compensated by using one of
	  the new assembler optimizations. Still, I see much code that can
	  be improved also for efficiency alone by clearing the situation
	  with some (shared) variables that don't need to be passed around
	  all the time...

2006-07-04 01:25  thor

	* trunk/src/Makefile.legacy: these -g were leftovers

2006-07-03 12:55  thor

	* trunk/src/Makefile.legacy, trunk/src/common.c,
	  trunk/src/common.h, trunk/src/control_generic.c,
	  trunk/src/layer3.c, trunk/src/layer3.h, trunk/src/mpg123.c,
	  trunk/src/mpg123.h: Main message: The gapless mode has been
	  enhanced to work more low-level (in layer3.c) and also to use
	  the Xing-given frame count to get the end straight. It should
	  work (tested, but not in every detail) both with the -k option
	  and terminal controlled seeking as well as control_generic
	  JUMPs. The current implementation adds some load that could be
	  reduced by putting the gapless checker code into behind flush
	  check instead of before but that needs additional care for track
	  end (where audio_flush is called externally). Apart from that
	  and some needed de-uglification it should be a nicely working
	  feature. Minor messages: frameNum is unsigned long (so bigger
	  that int and never < 0!); some parts of mpg123.c and common.c
	  did not honor these truths. But I don't claim that I catched all
	  occurences of such problems - see BUGS. Also, I fixed stuff in
	  print_stat with weird frame number estimations. Looks _much_
	  better now esp. when the frame count is known from Xing tag.

2006-07-03 12:16  njh

	* trunk/AUTHORS: Added Romain Dolbeau to AUTHORS file for his
	  Altivec work

2006-07-03 12:12  njh

	* trunk/configure.ac, trunk/src/Makefile.am,
	  trunk/src/dct64_altivec.c: Imported altivec support from mplayer
	  (and it works!) Still need to do CPU detection.

2006-07-03 12:11  thor

	* trunk/TODO: more and less of this

2006-06-27 00:54  thor

	* trunk/src/config.h.legacy: Did we start using C++ style comments?

2006-06-27 00:51  thor

	* trunk/src/common.c: a note on gapless hack updated

2006-06-26 22:57  thor

	* trunk/README.new: added note about more natural Ctrl+C

2006-06-26 22:43  thor

	* trunk/src/Makefile.legacy: some more flags by default

2006-06-26 22:40  thor

	* trunk/src/Makefile.legacy: ' seems to be dangerous together with
	  line-continuing \ ... made more "

2006-06-26 22:22  thor

	* trunk/configure.ac: generic linux support (?)

2006-06-26 22:04  thor

	* trunk/src/mpg123.c: Following DK's suggestion in a comment, I
	  disabled the Ctrl+C (SIGINT) hack when a control mode is active.
	  You can still do Ctrl+C to skip a song and twice to end playback
	  if you do not use the terminal or remote control mode. With
	  active control mode, a Ctrl+C now kills as expected (formerly,
	  it was just ignored).

2006-06-26 21:36  thor

	* trunk/src/getlopt.c, trunk/src/mpg123.c: There were several
	  option parsing regressions most probably caused by application
	  of Nicholas' changes to my code with changed command line
	  parsing. Fixed the obvious ones and made the option parser bail
	  out if it encouters such an error again.

2006-06-26 21:34  thor

	* trunk/MakeLegacy.sh, trunk/src/config.h.legacy: More legacy make
	  system working again with more crafted config.h.

2006-06-26 13:17  thor

	* trunk/AUTHORS, trunk/README.new: history in README.new,
	  maintainers in AUTHORS

2006-06-26 12:24  thor

	* trunk/src/audio.c, trunk/src/audio_aix.c,
	  trunk/src/audio_alib.c, trunk/src/audio_alsa.c,
	  trunk/src/audio_dummy.c, trunk/src/audio_esd.c,
	  trunk/src/audio_hp.c, trunk/src/audio_jack.c,
	  trunk/src/audio_libao.c, trunk/src/audio_macosx.c,

	  trunk/src/readers.c, trunk/src/system.c, trunk/src/tabinit.c,
	  trunk/src/wav.c, trunk/src/xfermem.c: Added inclusion config.h
	  everywhere to make sure we don't stumble over some missing
	  define later and search like crazy...

2006-06-26 12:22  thor

	* trunk/src/mpg123.c: Sorry, but these pointlessly broken lines
	  were _ugly_.

2006-06-26 12:11  thor

	* trunk/src/getlopt.c, trunk/src/term.c: These got some new-style
	  debugging through the terminal control bug hunt. Also, I want to
	  take the chance to hint at scripts/debugdef.pl that I added
	  previously: It is a Perl script generating the debug.h header in
	  a way to avoid variadic macros for fprintf. Result are debugN
	  macros that mean "debug line with N arguments". Examples:
	  debug1("Ok, there's one value: %i", var) debug3("now three of
	  them: %i %f %i", var1, var2, var3) simplest case: debug("just a
	  message");

2006-06-26 12:06  thor

	* trunk/scripts, trunk/scripts/debugdef.pl, trunk/src/debug.h,
	  trunk/src/mpg123.c: Hah! Found the place where terminal control
	  got killed! The option definition in mpg123.c lacked the type
	  specifier (a regression caused by merging). To find that, I
	  added debug.h for more convenient debugs.

2006-06-26 01:05  thor

	* trunk/README.new: small update on urls, frontend control

2006-06-26 01:04  thor

	* trunk/MakeLegacy.sh, trunk/configure.ac, trunk/src/Makefile.am,
	  trunk/src/audio_oss.c: - making audio_oss work again (didn't
	  include config.h); added needed bits for fake config.h. - adding
	  i586_dither as cpu variant: i586 assembler with dithering /
	  noise shaping

2006-06-25 23:52  thor

	* trunk/src/Makefile.legacy, trunk/src/control_tk3play.c,
	  trunk/src/control_tk3play.h, trunk/src/mpg123.c,
	  trunk/src/mpg123.h: Removing obsolete control interfaces (no one
	  uses them since a loong time).

2006-06-22 17:15  njh

	* trunk/MakeLegacy.sh: I won my fight with sed! yay!

2006-06-22 12:06  thor

	* trunk/README.sajber, trunk/debian, trunk/jukebox,
	  trunk/src/control_sajber.c: Removed debian dir and outdated
	  Sajber jukebox files. Have to check state of the tk3play
	  interface and modify Makefile.legacy (still all targets there).

2006-06-22 09:21  thor
