4 ------------------------------------------
5 0.?.? (to be announced) "neural discharge"
6 ------------------------------------------
8 The main change in this release is the major audio format handler
9 cleanup which removes some similar/duplicate code and makes it easier
10 to implement plugins for other audio formats. Of course, the usual mix
11 of other improvements/changes/bugfixes also made it into the release.
13 - simplified audio format handlers (some of the handling functions
14 were moved one layer up to the virtual streaming system).
15 - repositioning of mp3 streams is much faster, in particular for
16 jumping near the end of large mp3 files.
17 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
19 - fix a bug in para_filter that caused decoding of aac files
20 to start only after a few seconds.
21 - fix osx_writer hangs
22 - simplified dccp code (thanks to Gerrit Renker)
24 -----------------------------------------
25 0.2.15 (2007-02-16) "inductive resonance"
26 -----------------------------------------
28 Minor improvements, more documentation and a bunch of bug fixes.
30 - para_server: The server.users file is only read once on server
31 startup rather than for each connection
32 - mp3dec: Fix decoding of corrupt mp3 files
33 - afs (audio file sender) is now called vss (virtual streaming
34 system). Consequently, the permission flags specified in
35 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
36 become VSS_READ and VSS_WRITE respectively.
37 - para_audiod/para_filter: Fix a bug that caused the last chunk
38 of audio data not being written under certain circumstances
39 - audiod: compute the difference of server time and local time
41 - para_server/para_audiod: Fix some memory leaks
42 - documentation improvements
43 - configure.ac: fix checks for para_krell
46 -------------------------------------------
47 0.2.14 (2006-10-15) "transient singularity"
48 -------------------------------------------
50 The only major enhancement of this version is the osx writer which completes
51 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
52 until now for reasons beyond the scope of this changelog entry.
54 - new output plugin for Mac Os: the osx writer
55 - rename configure command line options from --enable-xxx-headers to
56 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
57 - configure: new command line options: --with-mad-headers,
58 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
59 - some robustness fixes
60 - dymamic audio format recognition for audiod
61 - para_server: new command line option: --autoplay_delay
62 - para_audiod: new command line option: --clock_diff_count
64 ---------------------------------------
65 0.2.13 (2006-07-14) "sonic convolution"
66 ---------------------------------------
68 A bunch of new features and core changes.
70 - the new paraslash scheduler, short and sweet.
71 - Support for m4a/mp4 files via the new aac audio format
72 handler/filter (requires libfaad).
73 - each writer has its own command line parser, just like
74 para_recv and para_filter.
75 - para_client and para_audioc use the error subsystem
76 - writers are integrated in para_audiod (currently linux-only)
77 - para_client is integrated in para_audiod
78 - random/playlist selector: improved info strings
79 - new audiod commands: tasks, kill
80 - update to libortp-0.10.1
81 - para_fade: wake time defaults to 8 hours from now
82 - update to autoconf-2.60
85 ------------------------------------------
86 0.2.12 (2006-05-12) "oriented abstraction"
87 ------------------------------------------
89 Many user-visible changes in this release and lots of new
93 - the new optional dccp sender/receiver. It uses the datagram
94 congestion control protocol. You'll need a fairly new kernel
96 - paraslash works on Mac OS X (thanks to Gerd Becker)
97 - para_play renamed to para_write
98 - modular output plugin design (writers) for para_write
99 - new file_writer output plugin for para_write
100 - compress filter speed improvements
101 - update to libortp-0.9.1
102 - update to gengetopt-2.17rc
103 - para_client no longer depends on libreadline (as the
104 code for the interactive mode was removed).
105 - gcc-2-95 is no longer a supported compiler. It may still
106 work, but it gets no more testing.
107 - the tarball no longer contains the screenshot images which
108 reduces its size quite a bit.
109 - configure: new command line options: --enable-mysql-headers
110 and --enable-mysql-libs
112 ------------------------------------
113 0.2.11 (2006-03-11) "atomic duality"
114 ------------------------------------
116 Here it is, the first paraslash release developed with git. There
117 are fairly many user-visible changes in this release. As two out of
118 the three "database tools" of paraslash don't use a database at all,
119 they are now called "audio file selectors" instead.
122 - the cdt command (change database tool) becomes chs (change
124 - no more colon separators: The syntax of some options of
125 para_audiod and para_filter have changed. Use --help for
126 more info (and some examples).
127 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
128 - switch from cvs to git (should've done that earlier)
129 - the new ipc subsystem
130 - new audio file selector: playlist
131 - para_server: the dopey selector is now called "random",
132 and is the default selector. Use the --selector option to
133 choose another selector at startup, or the chs command to
134 change the selector at runtime.
135 - X86_64 fixes (thanks to Steffen Klassert)
139 --------------------------------------
140 0.2.10 (2006-02-17) "cyclic attractor"
141 --------------------------------------
143 Huge documentation update, a scrollable window for para_gui, ortp
144 improvements, and of course many small fixes not mentioned here.
145 The diffstat below is rather misleading as most insertions are due
146 to the new source documentation.
149 - para_server also uses the new error subsystem
150 - lots of new documentation (UTSL)
152 - keysyms for cursor keys and for next/previous page keys
153 - scrollable output window
154 - new internal commands: scroll up/down, page up/down
155 - fix color of command output.
156 - ortp: the --chunk_time and --header flags are no longer needed
157 for para_recv/para_audiod as this information is now encoded in
158 each rtp packet sent by para_server.
161 -------------------------------------------
162 0.2.9 (2006-01-24) "progressive turbulence"
163 -------------------------------------------
165 Internal audiod receivers/filters, the new error subsystem and
166 a lot of small improvements.
168 - para_recv and para_filter are integrated into the para_audiod
169 binary, i.e. audiod no longer spawns a new process for
170 each receiver/filter. As para_recv and para_filter might be
171 useful as standalone programs, they still get built (linked
172 against the same object files that are also used for audiod).
173 - further ortp timing improvements should reduce the CPU usage
174 of the ortp receiver.
175 - improved audio grabbing. The 'grab' command of para_audiod
176 has its own set of command line options. Read the output of
177 "para_audioc help grab" for more info.
178 - oggdec: configurable input prebuffer size.
179 - the new error subsystem gives better error diagnostics
180 and reduces code size.
183 -----------------------------------------
184 0.2.8 (2006-01-02) "dynamic accumulation"
185 -----------------------------------------
187 The new modular filter design and the para_play-hangs bugfix.
189 - new executable: para_filter. It combines para_mp3dec,
190 para_oggdec and para_compress. It also adds a further filter
191 type, wav, that just inserts a wave header at the desired point
192 of the filter chain. All 'piping' is done in-memory (i.e. no
193 read/write operations are used).
194 - para_play: fix a stupid bug that caused it to hang under
195 certain circumstances.
198 -------------------------------------------
199 0.2.7 (2006-12-27) "transparent invariance"
200 -------------------------------------------
202 Not many user-visible changes but a fair amount of internal improvements.
205 - The http sender buffers data if it can not be sent
206 out immediately (because the socket is not writable). This
207 should prevent para_server from shutting down the connection
208 too early on a loaded network.
209 - para_play also prebuffers data if it is told to start at a
210 future time by the --start_time option.
211 - The return of para_recv: It combines para_ortp_recv and
212 para_http_recv. Use the --receiver option to switch between
213 the two. para_recv builds without libortp, but contains
214 only the http receiver in this case.
215 - update to ortp 0.8.1. As this ortp release contains incompatible
216 changes, para_recv-0.2.7 won't link against older ortp libs.
217 - improved ortp timings.
218 - use of gcc-extensions that #define away for non-gcc and
222 -------------------------------------------
223 0.2.6 (2005-10-29) "recursive compensation"
224 -------------------------------------------
226 Transparent session encryption (uses openssl's Alleged RC4 cipher),
227 the internal find command and several other improvements and cleanups.
229 - Encrypt the session if encryption is requested by the client
230 (default for para_client 0.2.6). This is backwards
231 compatible, so older clients can still connect to para_server
232 0.2.6. Use the new client option --plain to request an
233 uncrypted session (off by default, must be set to on in
234 order to connect to para_server 0.2.x with 0 <= x <= 5).
235 - para_server uses an internal function to locate audio files
236 rather than calling find(1). The server option
237 --mysql_audio_file_dir replaces --mysql_find_cmd.
238 - documentation update
240 - header file cleanup
241 - para_client code cleanup
242 - para_gui: faster display of output of display commands
245 ------------------------------------------
246 0.2.5 (2005-10-13) "aggressive_resolution"
247 ------------------------------------------
249 This release adds internal senders, i.e. no more external programs are
250 spawned for sending out the audio data. There are two different senders
251 available: The http sender and the ortp sender (former para_send which
252 is no longer needed).
254 The new sender code has a plugin-like design so it can be easily
255 extended should there be be any future need for supporting another
256 network streaming protocol. All senders are completely independent of
257 each other. In particular, the http and the ortp sender can operate
260 - new server command: sender to control senders at runtime.
261 Read the output of "para_server -h" and "para_client help
262 sender" for more information.
263 - para_recv renamed to para_ortp_recv
264 - new executable: para_http_recv, a simple command line
266 - major afs/mp3/ogg code simplifications due to internal
268 - ogg timing improvements
269 - fix several minor memory leaks (found by valgrind)
270 - empty stream definitions work again
271 - com_ne(): ignore errors on remove
272 - audiod: fix segfault on server restart
275 ---------------------------------------
276 0.2.4 (2005-09-21) "toxic anticipation"
277 ---------------------------------------
279 Several small improvements, fixes and the new grab command.
282 - new command: "grab" to grab the output of the stream reader
283 or any filters. Read the output of "para_audioc help grab"
284 for more information.
287 - audioc: new command line option: --bufsize to specify a
288 buffer size different from the default size 8192.
289 - improved error diagnostics for para_play.
290 - new configure option: --enable-ssldir so search for openssl in
292 - sdl_gui: Make it look nice again for 1024x768
293 - server: report total size of memory allocated with sbrk by malloc,
294 new command line option: --announce_time
297 -----------------------------------------
298 0.2.3 (2005-09-01) "hydrophilic movement"
299 -----------------------------------------
301 Two new executables and major feature enhancements.
303 - audiod filters: It is now possible to specify arbitrary many
304 (including none) filters for each supported audio
305 format. This can be used e.g. for normalizing volume,
306 transforming or grabbing the audio stream, or for using
307 visualizers. Read the output of "para_audiod -h" for the
308 syntax of the new --filter_cmd option.
309 - new executable: para_play, a tiny alsa player. It
310 can play wave files or raw pcm (16 bit little endian)
312 - new executable: para_compress, a dynamic range compressor
313 intended to keep audio output at a consistent volume. Derived
314 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
315 - audiod: New option: --stream_delay. This can be used in
316 a local network to syncronize the audio output of all
317 clients that play the same stream.
320 ------------------------------------------
321 0.2.2 (2005-08-19) "tangential excitation"
322 ------------------------------------------
324 Mostly internal changes in this release, but also some new commands
325 for the mysql database tool.
327 - cleanup exec.c, fix para_exec bug
328 - compile time loglevel (log messages below the given level
329 won't be compiled in, which reduces the size of the
331 - new log macros that shorten the size of the source code.
332 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
333 to send only zeros. With this workaround, para_audioc works
335 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
336 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
337 (new entry), "snp" (set numplayed). Read the manual for more
341 ---------------------------------------
342 0.2.1 (2005-08-15) "surreal experience"
343 ---------------------------------------
345 Here comes paraslash-0.2.1. It contains a couple of new features and,
346 surprise, only minor bug fixes.
348 - kill noisy mp3 debug message
349 - cleanup of the build system
350 - para_server and para_client directly use the crypto routines
351 of the openssl library rather than invoking the openssl command
353 - server/audiod: new option --user to switch to the given user
354 when invoked as root. Read the output of "para_server -h" for
356 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
357 status. Default: "para_audioc stat"
358 - sdl_gui: new option --pic_cmd to be used to download the picture.
359 Default: "para_client pic"
360 - audiod: 5 slots ought to be enough for everybody
361 - audiod: new status item: Uptime, kill hup command
365 ------------------------------------------
366 0.2.0 (2005-08-06) "distributed diffusion"
367 ------------------------------------------
369 After several month of increased development activity, paraslash-0.2.0
370 has arrived. It contains many new features and is much more
371 self-contained than the old 0.1.x series. Enjoy!
374 - para_server: fix hang on song change and crash on sighup.
375 Speed up mysql queries. The DIR_LIKE macro is gone.
376 - new executables: para_audiod, the local audio daemon that
377 starts playback (uses SCM_CREDENTIALS socket magic) and
378 para_audioc, the corresponding client.
379 - new executables: para_mp3dec/para_oggdec, two really teensy
380 decoders. para_mp3dec is based on libmad, para_oggdec requires
382 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
383 they are now called para_send and para_recv respectively.
384 - documentation updates
385 - para_gui is themable. For now there is the default theme that
386 looks as before and the simple theme: blue and easy.
387 - gui: audio streaming is now handled by audiod. Time display shows
388 playback time rather than streaming time
389 - slider: update to libzmw-0.2.0
390 - para_krell: fix crash on server shutdown
391 - switch from gzip to bzip2
394 ----------------------------------------
395 0.1.7 (2005-04-18) "melting penetration"
396 ----------------------------------------
398 The main change in this release is clearly the oggvorbis rewrite,
399 but there are also lots of smaller changes. If you intend to use both
400 the mp3 and the ogg plugin, it is recommended to use software mixing,
401 e.g. the dmix plugin which is provided by ALSA.
403 - new executables: para_ovsend and para_ovrecv for sending/receiving
404 oggvorbis files via rtp. Requires the open rtp library. Get it at
405 http://www.linphone.org/ortp/
406 - rewrite of the ogg_vorbis core code
407 - configure detects libzmw and, if detected, includes
408 para_slider to the list of binaries to be built by make
409 - server stream writers read from their associated fifo rather
411 - slider: two new sliders, lastplayed and numplayed
412 - fix nasty double free bug which caused random segfaults in case of
413 mp3 files with invalid header information
414 - gui: new command line option: --stream_timeout=seconds to
415 deactivate a slot if it is idle for that many seconds (default=`5')
419 ---------------------------------------
420 0.1.6 (2005-03-05) "asymptotic balance"
421 ---------------------------------------
423 Only little user-visible changes in this release. Mainly bugfixes and
424 core code cleanup. This is probably the most stable version ever if you
427 - fix several memory leaks
428 - rename default name of mysql database from "music" to "paraslash".
429 Use para_server's --mysql_database option if you do not want to
430 rename your old database.
431 - rework ogg vorbis code
432 - make update command work on mysql servers with LOCAL_INFILE
434 - gui: improved stream I/O (slots)
435 - simplified audio format API
436 - para_pob_ogg is gone
438 ------------------------------------
439 0.1.5 (2004-12-31) "opaque eternity"
440 ------------------------------------
442 Let's slide gently into the new year.
444 - new: para_slider (not built automatically, type "make
445 para_slider" to build). A toy for those who always felt that
446 creating stream definitions is difficult. See screenshots,
447 README and FEATURES for more info.
448 - improved signal handling. Fixes server segfault on SIGHUP
449 for linux kernels newer than Aug 24 2004 and makes para_gui
451 - reload database tool on SIGHUP
452 - improved help message for sl
453 - do not log "broken pipe" messages as errors. They are
455 - fix wrong error message on permission errors
457 -----------------------------------------
458 0.1.4 (2004-12-19) "tunneling transition"
459 -----------------------------------------
461 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
462 Hopefully, most of them got wiped out with this release. Some
463 enhancements went also in.
465 - improved error diagnostics for all commands
466 - stradd/picadd: overwrite previous contents if entry already
467 exists, rather than returning errors
468 - stradd: use current stream if invoked without args
469 - faster (and hopefully more stable) ogg-vorbis handling
470 - para_krell: reap children to avoid zombie-flooding in case
472 - si: report also server pid
473 - server: don't busy-loop if dbtool reports only invalid files.
474 - gui: CTRL+C works again, fix stream_read command line option
476 - fix mysql dbtool startup in case no database exists
477 - many small fixes and cleanups
479 ---------------------------------------
480 0.1.3: (2004-12-10) "vanishing inertia"
481 ---------------------------------------
483 Starting from this release, the database tools are integrated in the
484 server binary. This decreases server startup time, reduces code size
485 and speeds up database commands. However, the layout of the underlying
486 mysql database changed only slightly and 0.1.3 should be backwards
487 compatible in that respect.
491 - If mysql is not detected at compile time, or fails to init
492 at runtime, fall back to the dopey database tool which should
494 - para_dbtool and dbtool.conf are gone. All mysql specific
495 options are read from server.conf and are prefixed by 'mysql_'.
496 - new command: cdt (change database tool)
497 - new command line option: dbtool (choose startup database tool)
498 - The name of current stream is now stored in the database,
499 so paraslash remembers its current stream when restarted.
500 - new command: csp (change stream and play)
501 - para_gui also reports current database tool and server uptime
504 -------------------------------------------
505 0.1.2: (2004-11-28) "spherical fluctuation"
506 -------------------------------------------
508 Point release before the big dbtool changes go in.
510 - dbtool: rename ca to cam (copy all meta data). It now also
511 copies numplayed and lastplayed time as well as the picture
513 - fix endless-loop-bug caused by mp3 files with invalid header
515 -----------------------------------------
516 0.1.1: (2004-11-05) "floating atmosphere"
517 -----------------------------------------
520 - new dbtool command: mbox. Browse your sound-file collection
521 with your favorite mail reader.
522 - several small fixes
524 -------------------------------------
525 0.1.0: (2204-10-22) "rotating cortex"
526 -------------------------------------
528 - fix logging bug for loglevel > VERBOSE
530 - correct timings for vbr mp3s
531 - modular audio format support
532 - ogg-vorbis support (experimental)
533 - new server option: autoplay
535 -----------------------------------------
536 0.0.99: (2004-07-25) "harmonic deviation"
537 -----------------------------------------
539 - rename projectname from icc to paraslash (play, archive, rate
540 and stream large audio sets happily)
541 - paraslash is no longer restricted to one particular audio
543 - new dbtool commands (stradd, strq, strdel) for easy stream
544 managment w/o configuration file. That obsoletes stream_defs
545 file/config option for dbtool.
546 - picadd accepts jpeg data from stdin
547 - new server commands: ps (select previous stream), sc (song change)
548 - new default pictures for sdl_gui
549 - gui: new key_map option for binding commands and internal
550 functions to arbitrary keys, nice help screen, rip out
551 soundcard/linux specific stuff, avoid noise artefacts while jumping,
552 show silly logo on startup
553 - new executables: para_fade for fading volume, para_dbadm for
554 manipulating attributes
555 - cdb adds _all_ tables to mysql database
556 - revised and beautified documentation
557 - sample dbtool rewritten in C
560 ---------------------------------------------
561 0.0.98: (2003-12-26) "incremental smoothness"
562 ---------------------------------------------
564 - kick icecast in favour of poc. That removes some races and reduces
565 core code considerably.
566 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
567 give finer info on afs' status.
568 - gui can start decoder (see config options). Further new gui
569 commands: refresh (^L), jmp (F1-F10)
570 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
571 terminates gui. This fixes dead instances consuming memory
573 - new dbtool command: verb for sending verbatim sql queries.
574 - fix pid_list races (by removing pid_list)
581 - installation prefix now defaults to /usr/local
582 - new commands for gui: snozze, sleep and reread config
583 - config file for gui and sdl_gui
584 - fix problems with filenames containing funny characters
585 (reported by Thomas Forell)
586 - improved signal handling for gui, now it rereads conf on SIGHUP
587 - new dbtool command: cdb (create database)
588 - switch from argtable to gengetopt
589 - major code cleanup and speed improvements
590 - fix several potential buffer overflows
591 - many small fixes and cleanups
597 - easy stream_defs syntax
598 - sdl_gui can display images associated to the file being played
599 - Major feature enhancements for icc_gui including dynamic text
600 placement and the top/bottom window design
601 - vrfy/clean now also checks for NULL values in attributes as
602 well as for invalid picture pointers
603 - fix long outstanding case sensitivity bug
604 - many small fixes and cleanups
610 - sdl gui runs much faster
611 - new dbtool command: ca (copy attributes)
612 - count and display number of times the song has been played
613 - new feature: scoring
614 - command line options for sdl_gui
615 - simpler syntax of streams file
616 - decrease network traffic of stat
618 - many small fixes and cleanups
624 - new server command: ns (next stream)
625 - new icc_gui command: c (change stream)
627 - stat shows also id3 tag info
629 - log flodding bug fixed
630 - many small fixes and cleanups
637 - icc_gui sets volume directly (linux only)
638 - proper locking that fixes some races
639 - fix security bug that caused commands to be executed even
