5 0.?.? (to be announced) "neural discharge"
6 ------------------------------------------
7
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.
12
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
18 and AFS_WRITE.
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)
23
24 -----------------------------------------
25 0.2.15 (2007-02-16) "inductive resonance"
26 -----------------------------------------
27
28 Minor improvements, more documentation and a bunch of bug fixes.
29
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
40 correctly
41 - para_server/para_audiod: Fix some memory leaks
42 - documentation improvements
43 - configure.ac: fix checks for para_krell
44 - new man pages
45
46 -------------------------------------------
47 0.2.14 (2006-10-15) "transient singularity"
48 -------------------------------------------
49
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.
53
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
63
64 ---------------------------------------
65 0.2.13 (2006-07-14) "sonic convolution"
66 ---------------------------------------
67
68 A bunch of new features and core changes.
69
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
83
84
85 ------------------------------------------
86 0.2.12 (2006-05-12) "oriented abstraction"
87 ------------------------------------------
88
89 Many user-visible changes in this release and lots of new
90 features:
91
92
93 - the new optional dccp sender/receiver. It uses the datagram
94 congestion control protocol. You'll need a fairly new kernel
95 for this.
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
111
112 ------------------------------------
113 0.2.11 (2006-03-11) "atomic duality"
114 ------------------------------------
115
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.
120
121
122 - the cdt command (change database tool) becomes chs (change
123 selector)
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)
136 - para_play fixes
137
138
139 --------------------------------------
140 0.2.10 (2006-02-17) "cyclic attractor"
141 --------------------------------------
142
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.
147
148 - autoconf cleanup
149 - para_server also uses the new error subsystem
150 - lots of new documentation (UTSL)
151 - gui improvements:
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.
159
160
161 -------------------------------------------
162 0.2.9 (2006-01-24) "progressive turbulence"
163 -------------------------------------------
164
165 Internal audiod receivers/filters, the new error subsystem and
166 a lot of small improvements.
167
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.
181
182
183 -----------------------------------------
184 0.2.8 (2006-01-02) "dynamic accumulation"
185 -----------------------------------------
186
187 The new modular filter design and the para_play-hangs bugfix.
188
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.
196
197
198 -------------------------------------------
199 0.2.7 (2006-12-27) "transparent invariance"
200 -------------------------------------------
201
202 Not many user-visible changes but a fair amount of internal improvements.
203
204
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
219 gcc < 3.0.
220
221
222 -------------------------------------------
223 0.2.6 (2005-10-29) "recursive compensation"
224 -------------------------------------------
225
226 Transparent session encryption (uses openssl's Alleged RC4 cipher),
227 the internal find command and several other improvements and cleanups.
228
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
239 - man pages
240 - header file cleanup
241 - para_client code cleanup
242 - para_gui: faster display of output of display commands
243
244
245 ------------------------------------------
246 0.2.5 (2005-10-13) "aggressive_resolution"
247 ------------------------------------------
248
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).
253
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
258 in parallel.
259
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
265 http receiver.
266 - major afs/mp3/ogg code simplifications due to internal
267 senders.
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
273
274
275 ---------------------------------------
276 0.2.4 (2005-09-21) "toxic anticipation"
277 ---------------------------------------
278
279 Several small improvements, fixes and the new grab command.
280
281 - audiod:
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.
285 - fix memory leak
286 - code cleanup
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
291 non-standard places
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
295
296
297 -----------------------------------------
298 0.2.3 (2005-09-01) "hydrophilic movement"
299 -----------------------------------------
300
301 Two new executables and major feature enhancements.
302
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)
311 from stdin.
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.
318
319
320 ------------------------------------------
321 0.2.2 (2005-08-19) "tangential excitation"
322 ------------------------------------------
323
324 Mostly internal changes in this release, but also some new commands
325 for the mysql database tool.
326
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
330 resulting binaries)
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
334 again.
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
338 information.
339
340
341 ---------------------------------------
342 0.2.1 (2005-08-15) "surreal experience"
343 ---------------------------------------
344
345 Here comes paraslash-0.2.1. It contains a couple of new features and,
346 surprise, only minor bug fixes.
347
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
352 line utitlity
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
355 more information.
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
362
363
364
365 ------------------------------------------
366 0.2.0 (2005-08-06) "distributed diffusion"
367 ------------------------------------------
368
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!
372
373
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
381 libvorbisfile.
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
392
393
394 ----------------------------------------
395 0.1.7 (2005-04-18) "melting penetration"
396 ----------------------------------------
397
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.
402
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
410 than from stdin
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')
416 - diffstats
417
418
419 ---------------------------------------
420 0.1.6 (2005-03-05) "asymptotic balance"
421 ---------------------------------------
422
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
425 stick to mp3...
426
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
433 disabled
434 - gui: improved stream I/O (slots)
435 - simplified audio format API
436 - para_pob_ogg is gone
437
438 ------------------------------------
439 0.1.5 (2004-12-31) "opaque eternity"
440 ------------------------------------
441
442 Let's slide gently into the new year.
443
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
450 race-free.
451 - reload database tool on SIGHUP
452 - improved help message for sl
453 - do not log "broken pipe" messages as errors. They are
454 perfectly ok.
455 - fix wrong error message on permission errors
456
457 -----------------------------------------
458 0.1.4 (2004-12-19) "tunneling transition"
459 -----------------------------------------
460
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.
464
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
471 no server is running
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
475 - fix pic_add, hist
476 - fix mysql dbtool startup in case no database exists
477 - many small fixes and cleanups
478
479 ---------------------------------------
480 0.1.3: (2004-12-10) "vanishing inertia"
481 ---------------------------------------
482
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.
488
489 Visible changes:
490
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
493 always work.
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
502
503
504 -------------------------------------------
505 0.1.2: (2004-11-28) "spherical fluctuation"
506 -------------------------------------------
507
508 Point release before the big dbtool changes go in.
509
510 - dbtool: rename ca to cam (copy all meta data). It now also
511 copies numplayed and lastplayed time as well as the picture
512 id.
513 - fix endless-loop-bug caused by mp3 files with invalid header
514
515 -----------------------------------------
516 0.1.1: (2004-11-05) "floating atmosphere"
517 -----------------------------------------
518
519 - gkrellm plugin
520 - new dbtool command: mbox. Browse your sound-file collection
521 with your favorite mail reader.
522 - several small fixes
523
524 -------------------------------------
525 0.1.0: (2204-10-22) "rotating cortex"
526 -------------------------------------
527
528 - fix logging bug for loglevel > VERBOSE
529 - fix skip command
530 - correct timings for vbr mp3s
531 - modular audio format support
532 - ogg-vorbis support (experimental)
533 - new server option: autoplay
534
535 -----------------------------------------
536 0.0.99: (2004-07-25) "harmonic deviation"
537 -----------------------------------------
538
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
542 streaming software
543 - new dbtool commands (stradd, strq, strdel) for easy stream
544 managment w/o configuration file. That obsoletes stream_defs
