5 0.?.? (to be announced) "sonic convolution"
6 -------------------------------------------
7
8 A bunch of new features and core changes.
9
10 - the new paraslash scheduler, short and sweet.
11 - Support for m4a files via the new aac filter/ and audio
12 format handler. (requires libfaad)
13 - new writer: osxplay (thanks to Gerd Becker)
14 - writers are integrated into para_audiod
15 - each writer of para_write has its own command line parser,
16 just like para_recv and para_filter.
17 - random/playlist selector: improved info strings
18 - new audiod commands: tasks, kill
19 - para_client/para_audioc use the error subsystem
20
21
22 ------------------------------------------
23 0.2.12 (2006-05-12) "oriented abstraction"
24 ------------------------------------------
25
26 Many user-visible changes in this release and lots of new
27 features:
28
29
30 - the new optional dccp sender/receiver. It uses the datagram
31 congestion control protocol. You'll need a fairly new kernel
32 for this.
33 - paraslash works on Mac OS X (thanks to Gerd Becker)
34 - para_play renamed to para_write
35 - modular output plugin design (writers) for para_write
36 - new file_writer output plugin for para_write
37 - compress filter speed improvements
38 - update to libortp-0.9.1
39 - update to gengetopt-2.17rc
40 - para_client no longer depends on libreadline (as the
41 code for the interactive mode was removed).
42 - gcc-2-95 is no longer a supported compiler. It may still
43 work, but it gets no more testing.
44 - the tarball no longer contains the screenshot images which
45 reduces its size quite a bit.
46 - configure: new command line options: --enable-mysql-headers
47 and --enable-mysql-libs
48
49 ------------------------------------
50 0.2.11 (2006-03-11) "atomic duality"
51 ------------------------------------
52
53 Here it is, the first paraslash release developed with git. There
54 are fairly many user-visible changes in this release. As two out of
55 the three "database tools" of paraslash don't use a database at all,
56 they are now called "audio file selectors" instead.
57
58
59 - the cdt command (change database tool) becomes chs (change
60 selector)
61 - no more colon separators: The syntax of some options of
62 para_audiod and para_filter have changed. Use --help for
63 more info (and some examples).
64 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
65 - switch from cvs to git (should've done that earlier)
66 - the new ipc subsystem
67 - new audio file selector: playlist
68 - para_server: the dopey selector is now called "random",
69 and is the default selector. Use the --selector option to
70 choose another selector at startup, or the chs command to
71 change the selector at runtime.
72 - X86_64 fixes (thanks to Steffen Klassert)
73 - para_play fixes
74
75
76 --------------------------------------
77 0.2.10 (2006-02-17) "cyclic attractor"
78 --------------------------------------
79
80 Huge documentation update, a scrollable window for para_gui, ortp
81 improvements, and of course many small fixes not mentioned here.
82 The diffstat below is rather misleading as most insertions are due
83 to the new source documentation.
84
85 - autoconf cleanup
86 - para_server also uses the new error subsystem
87 - lots of new documentation (UTSL)
88 - gui improvements:
89 - keysyms for cursor keys and for next/previous page keys
90 - scrollable output window
91 - new internal commands: scroll up/down, page up/down
92 - fix color of command output.
93 - ortp: the --chunk_time and --header flags are no longer needed
94 for para_recv/para_audiod as this information is now encoded in
95 each rtp packet sent by para_server.
96
97
98 -------------------------------------------
99 0.2.9 (2006-01-24) "progressive turbulence"
100 -------------------------------------------
101
102 Internal audiod receivers/filters, the new error subsystem and
103 a lot of small improvements.
104
105 - para_recv and para_filter are integrated into the para_audiod
106 binary, i.e. audiod no longer spawns a new process for
107 each receiver/filter. As para_recv and para_filter might be
108 useful as standalone programs, they still get built (linked
109 against the same object files that are also used for audiod).
110 - further ortp timing improvements should reduce the CPU usage
111 of the ortp receiver.
112 - improved audio grabbing. The 'grab' command of para_audiod
113 has its own set of command line options. Read the output of
114 "para_audioc help grab" for more info.
115 - oggdec: configurable input prebuffer size.
116 - the new error subsystem gives better error diagnostics
117 and reduces code size.
118
119
120 -----------------------------------------
121 0.2.8 (2006-01-02) "dynamic accumulation"
122 -----------------------------------------
123
124 The new modular filter design and the para_play-hangs bugfix.
125
126 - new executable: para_filter. It combines para_mp3dec,
127 para_oggdec and para_compress. It also adds a further filter
128 type, wav, that just inserts a wave header at the desired point
129 of the filter chain. All 'piping' is done in-memory (i.e. no
130 read/write operations are used).
131 - para_play: fix a stupid bug that caused it to hang under
132 certain circumstances.
133
134
135 -------------------------------------------
136 0.2.7 (2006-12-27) "transparent invariance"
137 -------------------------------------------
138
139 Not many user-visible changes but a fair amount of internal improvements.
140
141
142 - The http sender buffers data if it can not be sent
143 out immediately (because the socket is not writable). This
144 should prevent para_server from shutting down the connection
145 too early on a loaded network.
146 - para_play also prebuffers data if it is told to start at a
147 future time by the --start_time option.
148 - The return of para_recv: It combines para_ortp_recv and
149 para_http_recv. Use the --receiver option to switch between
150 the two. para_recv builds without libortp, but contains
151 only the http receiver in this case.
152 - update to ortp 0.8.1. As this ortp release contains incompatible
153 changes, para_recv-0.2.7 won't link against older ortp libs.
154 - improved ortp timings.
155 - use of gcc-extensions that #define away for non-gcc and
156 gcc < 3.0.
157
158
159 -------------------------------------------
160 0.2.6 (2005-10-29) "recursive compensation"
161 -------------------------------------------
162
163 Transparent session encryption (uses openssl's Alleged RC4 cipher),
164 the internal find command and several other improvements and cleanups.
165
166 - Encrypt the session if encryption is requested by the client
167 (default for para_client 0.2.6). This is backwards
168 compatible, so older clients can still connect to para_server
169 0.2.6. Use the new client option --plain to request an
170 uncrypted session (off by default, must be set to on in
171 order to connect to para_server 0.2.x with 0 <= x <= 5).
172 - para_server uses an internal function to locate audio files
173 rather than calling find(1). The server option
174 --mysql_audio_file_dir replaces --mysql_find_cmd.
175 - documentation update
176 - man pages
177 - header file cleanup
178 - para_client code cleanup
179 - para_gui: faster display of output of display commands
180
181
182 ------------------------------------------
183 0.2.5 (2005-10-13) "aggressive_resolution"
184 ------------------------------------------
185
186 This release adds internal senders, i.e. no more external programs are
187 spawned for sending out the audio data. There are two different senders
188 available: The http sender and the ortp sender (former para_send which
189 is no longer needed).
190
191 The new sender code has a plugin-like design so it can be easily
192 extended should there be be any future need for supporting another
193 network streaming protocol. All senders are completely independent of
194 each other. In particular, the http and the ortp sender can operate
195 in parallel.
196
197 - new server command: sender to control senders at runtime.
198 Read the output of "para_server -h" and "para_client help
199 sender" for more information.
200 - para_recv renamed to para_ortp_recv
201 - new executable: para_http_recv, a simple command line
202 http receiver.
203 - major afs/mp3/ogg code simplifications due to internal
204 senders.
205 - ogg timing improvements
206 - fix several minor memory leaks (found by valgrind)
207 - empty stream definitions work again
208 - com_ne(): ignore errors on remove
209 - audiod: fix segfault on server restart
210
211
212 ---------------------------------------
213 0.2.4 (2005-09-21) "toxic anticipation"
214 ---------------------------------------
215
216 Several small improvements, fixes and the new grab command.
217
218 - audiod:
219 - new command: "grab" to grab the output of the stream reader
220 or any filters. Read the output of "para_audioc help grab"
221 for more information.
222 - fix memory leak
223 - code cleanup
224 - audioc: new command line option: --bufsize to specify a
225 buffer size different from the default size 8192.
226 - improved error diagnostics for para_play.
227 - new configure option: --enable-ssldir so search for openssl in
228 non-standard places
229 - sdl_gui: Make it look nice again for 1024x768
230 - server: report total size of memory allocated with sbrk by malloc,
231 new command line option: --announce_time
232
233
234 -----------------------------------------
235 0.2.3 (2005-09-01) "hydrophilic movement"
236 -----------------------------------------
237
238 Two new executables and major feature enhancements.
239
240 - audiod filters: It is now possible to specify arbitrary many
241 (including none) filters for each supported audio
242 format. This can be used e.g. for normalizing volume,
243 transforming or grabbing the audio stream, or for using
244 visualizers. Read the output of "para_audiod -h" for the
245 syntax of the new --filter_cmd option.
246 - new executable: para_play, a tiny alsa player. It
247 can play wave files or raw pcm (16 bit little endian)
248 from stdin.
249 - new executable: para_compress, a dynamic range compressor
250 intended to keep audio output at a consistent volume. Derived
251 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
252 - audiod: New option: --stream_delay. This can be used in
253 a local network to syncronize the audio output of all
254 clients that play the same stream.
255
256
257 ------------------------------------------
258 0.2.2 (2005-08-19) "tangential excitation"
259 ------------------------------------------
260
261 Mostly internal changes in this release, but also some new commands
262 for the mysql database tool.
263
264 - cleanup exec.c, fix para_exec bug
265 - compile time loglevel (log messages below the given level
266 won't be compiled in, which reduces the size of the
267 resulting binaries)
268 - new log macros that shorten the size of the source code.
269 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
270 to send only zeros. With this workaround, para_audioc works
271 again.
272 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
273 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
274 (new entry), "snp" (set numplayed). Read the manual for more
275 information.
276
277
278 ---------------------------------------
279 0.2.1 (2005-08-15) "surreal experience"
280 ---------------------------------------
281
282 Here comes paraslash-0.2.1. It contains a couple of new features and,
283 surprise, only minor bug fixes.
284
285 - kill noisy mp3 debug message
286 - cleanup of the build system
287 - para_server and para_client directly use the crypto routines
288 of the openssl library rather than invoking the openssl command
289 line utitlity
290 - server/audiod: new option --user to switch to the given user
291 when invoked as root. Read the output of "para_server -h" for
292 more information.
293 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
294 status. Default: "para_audioc stat"
295 - sdl_gui: new option --pic_cmd to be used to download the picture.
296 Default: "para_client pic"
297 - audiod: 5 slots ought to be enough for everybody
298 - audiod: new status item: Uptime, kill hup command
299
300
301
302 ------------------------------------------
303 0.2.0 (2005-08-06) "distributed diffusion"
304 ------------------------------------------
305
306 After several month of increased development activity, paraslash-0.2.0
307 has arrived. It contains many new features and is much more
308 self-contained than the old 0.1.x series. Enjoy!
309
310
311 - para_server: fix hang on song change and crash on sighup.
312 Speed up mysql queries. The DIR_LIKE macro is gone.
313 - new executables: para_audiod, the local audio daemon that
314 starts playback (uses SCM_CREDENTIALS socket magic) and
315 para_audioc, the corresponding client.
316 - new executables: para_mp3dec/para_oggdec, two really teensy
317 decoders. para_mp3dec is based on libmad, para_oggdec requires
318 libvorbisfile.
319 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
320 they are now called para_send and para_recv respectively.
321 - documentation updates
322 - para_gui is themable. For now there is the default theme that
323 looks as before and the simple theme: blue and easy.
324 - gui: audio streaming is now handled by audiod. Time display shows
325 playback time rather than streaming time
326 - slider: update to libzmw-0.2.0
327 - para_krell: fix crash on server shutdown
328 - switch from gzip to bzip2
329
330
331 ----------------------------------------
332 0.1.7 (2005-04-18) "melting penetration"
333 ----------------------------------------
334
335 The main change in this release is clearly the oggvorbis rewrite,
336 but there are also lots of smaller changes. If you intend to use both
337 the mp3 and the ogg plugin, it is recommended to use software mixing,
338 e.g. the dmix plugin which is provided by ALSA.
339
340 - new executables: para_ovsend and para_ovrecv for sending/receiving
341 oggvorbis files via rtp. Requires the open rtp library. Get it at
342 http://www.linphone.org/ortp/
343 - rewrite of the ogg_vorbis core code
344 - configure detects libzmw and, if detected, includes
345 para_slider to the list of binaries to be built by make
346 - server stream writers read from their associated fifo rather
347 than from stdin
348 - slider: two new sliders, lastplayed and numplayed
349 - fix nasty double free bug which caused random segfaults in case of
350 mp3 files with invalid header information
351 - gui: new command line option: --stream_timeout=seconds to
352 deactivate a slot if it is idle for that many seconds (default=`5')
353 - diffstats
354
355
356 ---------------------------------------
357 0.1.6 (2005-03-05) "asymptotic balance"
358 ---------------------------------------
359
360 Only little user-visible changes in this release. Mainly bugfixes and
361 core code cleanup. This is probably the most stable version ever if you
362 stick to mp3...
363
364 - fix several memory leaks
365 - rename default name of mysql database from "music" to "paraslash".
366 Use para_server's --mysql_database option if you do not want to
367 rename your old database.
368 - rework ogg vorbis code
369 - make update command work on mysql servers with LOCAL_INFILE
370 disabled
371 - gui: improved stream I/O (slots)
372 - simplified audio format API
373 - para_pob_ogg is gone
374
375 ------------------------------------
376 0.1.5 (2004-12-31) "opaque eternity"
377 ------------------------------------
378
379 Let's slide gently into the new year.
380
381 - new: para_slider (not built automatically, type "make
382 para_slider" to build). A toy for those who always felt that
383 creating stream definitions is difficult. See screenshots,
384 README and FEATURES for more info.
385 - improved signal handling. Fixes server segfault on SIGHUP
386 for linux kernels newer than Aug 24 2004 and makes para_gui
387 race-free.
388 - reload database tool on SIGHUP
389 - improved help message for sl
390 - do not log "broken pipe" messages as errors. They are
391 perfectly ok.
392 - fix wrong error message on permission errors
393
394 -----------------------------------------
395 0.1.4 (2004-12-19) "tunneling transition"
396 -----------------------------------------
397
398 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
399 Hopefully, most of them got wiped out with this release. Some
400 enhancements went also in.
401
402 - improved error diagnostics for all commands
403 - stradd/picadd: overwrite previous contents if entry already
404 exists, rather than returning errors
405 - stradd: use current stream if invoked without args
406 - faster (and hopefully more stable) ogg-vorbis handling
407 - para_krell: reap children to avoid zombie-flooding in case
408 no server is running
409 - si: report also server pid
410 - server: don't busy-loop if dbtool reports only invalid files.
411 - gui: CTRL+C works again, fix stream_read command line option
412 - fix pic_add, hist
413 - fix mysql dbtool startup in case no database exists
414 - many small fixes and cleanups
415
416 ---------------------------------------
417 0.1.3: (2004-12-10) "vanishing inertia"
418 ---------------------------------------
419
420 Starting from this release, the database tools are integrated in the
421 server binary. This decreases server startup time, reduces code size
422 and speeds up database commands. However, the layout of the underlying
423 mysql database changed only slightly and 0.1.3 should be backwards
424 compatible in that respect.
425
426 Visible changes:
427
428 - If mysql is not detected at compile time, or fails to init
429 at runtime, fall back to the dopey database tool which should
430 always work.
431 - para_dbtool and dbtool.conf are gone. All mysql specific
432 options are read from server.conf and are prefixed by 'mysql_'.
433 - new command: cdt (change database tool)
434 - new command line option: dbtool (choose startup database tool)
435 - The name of current stream is now stored in the database,
436 so paraslash remembers its current stream when restarted.
437 - new command: csp (change stream and play)
438 - para_gui also reports current database tool and server uptime
439
440
441 -------------------------------------------
442 0.1.2: (2004-11-28) "spherical fluctuation"
443 -------------------------------------------
444
445 Point release before the big dbtool changes go in.
446
447 - dbtool: rename ca to cam (copy all meta data). It now also
448 copies numplayed and lastplayed time as well as the picture
449 id.
450 - fix endless-loop-bug caused by mp3 files with invalid header
451
452 -----------------------------------------
453 0.1.1: (2004-11-05) "floating atmosphere"
454 -----------------------------------------
455
456 - gkrellm plugin
457 - new dbtool command: mbox. Browse your sound-file collection
458 with your favorite mail reader.
459 - several small fixes
460
461 -------------------------------------
462 0.1.0: (2204-10-22) "rotating cortex"
463 -------------------------------------
464
465 - fix logging bug for loglevel > VERBOSE
466 - fix skip command
467 - correct timings for vbr mp3s
468 - modular audio format support
469 - ogg-vorbis support (experimental)
470 - new server option: autoplay
471
472 -----------------------------------------
473 0.0.99: (2004-07-25) "harmonic deviation"
474 -----------------------------------------
475
476 - rename projectname from icc to paraslash (play, archive, rate
477 and stream large audio sets happily)
478 - paraslash is no longer restricted to one particular audio
479 streaming software
480 - new dbtool commands (stradd, strq, strdel) for easy stream
481 managment w/o configuration file. That obsoletes stream_defs
482 file/config option for dbtool.
483 - picadd accepts jpeg data from stdin
484 - new server commands: ps (select previous stream), sc (song change)
485 - new default pictures for sdl_gui
486 - gui: new key_map option for binding commands and internal
487 functions to arbitrary keys, nice help screen, rip out
488 soundcard/linux specific stuff, avoid noise artefacts while jumping,
489 show silly logo on startup
490 - new executables: para_fade for fading volume, para_dbadm for
491 manipulating attributes
492 - cdb adds _all_ tables to mysql database
493 - revised and beautified documentation
494 - sample dbtool rewritten in C
495 - autoconf
496
497 ---------------------------------------------
498 0.0.98: (2003-12-26) "incremental smoothness"
499 ---------------------------------------------
500
501 - kick icecast in favour of poc. That removes some races and reduces
502 core code considerably.
503 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
504 give finer info on afs' status.
505 - gui can start decoder (see config options). Further new gui
506 commands: refresh (^L), jmp (F1-F10)
507 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
508 terminates gui. This fixes dead instances consuming memory
509 continuously.
510 - new dbtool command: verb for sending verbatim sql queries.
511 - fix pid_list races (by removing pid_list)
512 - codename funnies
513
514 --------------------
515 0.0.97: (2003-10-26)
516 --------------------
517
518 - installation prefix now defaults to /usr/local
519 - new commands for gui: snozze, sleep and reread config
520 - config file for gui and sdl_gui
521 - fix problems with filenames containing funny characters
522 (reported by Thomas Forell)
523 - improved signal handling for gui, now it rereads conf on SIGHUP
524 - new dbtool command: cdb (create database)
525 - switch from argtable to gengetopt
526 - major code cleanup and speed improvements
527 - fix several potential buffer overflows
528 - many small fixes and cleanups
529
530 -------------------
531 0.0.96 (2003-08-30)
532 -------------------
533
534 - easy stream_defs syntax
535 - sdl_gui can display images associated to the file being played
536 - Major feature enhancements for icc_gui including dynamic text
537 placement and the top/bottom window design
538 - vrfy/clean now also checks for NULL values in attributes as
539 well as for invalid picture pointers
540 - fix long outstanding case sensitivity bug
541 - many small fixes and cleanups
542
543 -------------------
544 0.0.95 (2003-06-29)
545 -------------------
546
547 - sdl gui runs much faster
548 - new dbtool command: ca (copy attributes)
549 - count and display number of times the song has been played
550 - new feature: scoring
551 - command line options for sdl_gui
552 - simpler syntax of streams file
