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 (most of the handling functions
14 were moved one layer up to the virtual streaming system).
15 - para_server uses mmap to read audio files
16 - repositioning of mp3 streams is much faster, in particular for
17 jumping near the end of large mp3 files.
18 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
19 and AFS_WRITE.
20 - fix a bug in para_filter that caused decoding of aac files
21 to start only after a few seconds.
22 - fix osx_writer hangs
23 - simplified dccp code (thanks to Gerrit Renker)
24 - the compress filter works also on big endian systems (ppc)
25
26 -----------------------------------------
27 0.2.15 (2007-02-16) "inductive resonance"
28 -----------------------------------------
29
30 Minor improvements, more documentation and a bunch of bug fixes.
31
32 - para_server: The server.users file is only read once on server
33 startup rather than for each connection
34 - mp3dec: Fix decoding of corrupt mp3 files
35 - afs (audio file sender) is now called vss (virtual streaming
36 system). Consequently, the permission flags specified in
37 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
38 become VSS_READ and VSS_WRITE respectively.
39 - para_audiod/para_filter: Fix a bug that caused the last chunk
40 of audio data not being written under certain circumstances
41 - audiod: compute the difference of server time and local time
42 correctly
43 - para_server/para_audiod: Fix some memory leaks
44 - documentation improvements
45 - configure.ac: fix checks for para_krell
46 - new man pages
47
48 -------------------------------------------
49 0.2.14 (2006-10-15) "transient singularity"
50 -------------------------------------------
51
52 The only major enhancement of this version is the osx writer which completes
53 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
54 until now for reasons beyond the scope of this changelog entry.
55
56 - new output plugin for Mac Os: the osx writer
57 - rename configure command line options from --enable-xxx-headers to
58 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
59 - configure: new command line options: --with-mad-headers,
60 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
61 - some robustness fixes
62 - dymamic audio format recognition for audiod
63 - para_server: new command line option: --autoplay_delay
64 - para_audiod: new command line option: --clock_diff_count
65
66 ---------------------------------------
67 0.2.13 (2006-07-14) "sonic convolution"
68 ---------------------------------------
69
70 A bunch of new features and core changes.
71
72 - the new paraslash scheduler, short and sweet.
73 - Support for m4a/mp4 files via the new aac audio format
74 handler/filter (requires libfaad).
75 - each writer has its own command line parser, just like
76 para_recv and para_filter.
77 - para_client and para_audioc use the error subsystem
78 - writers are integrated in para_audiod (currently linux-only)
79 - para_client is integrated in para_audiod
80 - random/playlist selector: improved info strings
81 - new audiod commands: tasks, kill
82 - update to libortp-0.10.1
83 - para_fade: wake time defaults to 8 hours from now
84 - update to autoconf-2.60
85
86
87 ------------------------------------------
88 0.2.12 (2006-05-12) "oriented abstraction"
89 ------------------------------------------
90
91 Many user-visible changes in this release and lots of new
92 features:
93
94
95 - the new optional dccp sender/receiver. It uses the datagram
96 congestion control protocol. You'll need a fairly new kernel
97 for this.
98 - paraslash works on Mac OS X (thanks to Gerd Becker)
99 - para_play renamed to para_write
100 - modular output plugin design (writers) for para_write
101 - new file_writer output plugin for para_write
102 - compress filter speed improvements
103 - update to libortp-0.9.1
104 - update to gengetopt-2.17rc
105 - para_client no longer depends on libreadline (as the
106 code for the interactive mode was removed).
107 - gcc-2-95 is no longer a supported compiler. It may still
108 work, but it gets no more testing.
109 - the tarball no longer contains the screenshot images which
110 reduces its size quite a bit.
111 - configure: new command line options: --enable-mysql-headers
112 and --enable-mysql-libs
113
114 ------------------------------------
115 0.2.11 (2006-03-11) "atomic duality"
116 ------------------------------------
117
118 Here it is, the first paraslash release developed with git. There
119 are fairly many user-visible changes in this release. As two out of
120 the three "database tools" of paraslash don't use a database at all,
121 they are now called "audio file selectors" instead.
122
123
124 - the cdt command (change database tool) becomes chs (change
125 selector)
126 - no more colon separators: The syntax of some options of
127 para_audiod and para_filter have changed. Use --help for
128 more info (and some examples).
129 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
130 - switch from cvs to git (should've done that earlier)
131 - the new ipc subsystem
132 - new audio file selector: playlist
133 - para_server: the dopey selector is now called "random",
134 and is the default selector. Use the --selector option to
135 choose another selector at startup, or the chs command to
136 change the selector at runtime.
137 - X86_64 fixes (thanks to Steffen Klassert)
138 - para_play fixes
139
140
141 --------------------------------------
142 0.2.10 (2006-02-17) "cyclic attractor"
143 --------------------------------------
144
145 Huge documentation update, a scrollable window for para_gui, ortp
146 improvements, and of course many small fixes not mentioned here.
147 The diffstat below is rather misleading as most insertions are due
148 to the new source documentation.
149
150 - autoconf cleanup
151 - para_server also uses the new error subsystem
152 - lots of new documentation (UTSL)
153 - gui improvements:
154 - keysyms for cursor keys and for next/previous page keys
155 - scrollable output window
156 - new internal commands: scroll up/down, page up/down
157 - fix color of command output.
158 - ortp: the --chunk_time and --header flags are no longer needed
159 for para_recv/para_audiod as this information is now encoded in
160 each rtp packet sent by para_server.
161
162
163 -------------------------------------------
164 0.2.9 (2006-01-24) "progressive turbulence"
165 -------------------------------------------
166
167 Internal audiod receivers/filters, the new error subsystem and
168 a lot of small improvements.
169
170 - para_recv and para_filter are integrated into the para_audiod
171 binary, i.e. audiod no longer spawns a new process for
172 each receiver/filter. As para_recv and para_filter might be
173 useful as standalone programs, they still get built (linked
174 against the same object files that are also used for audiod).
175 - further ortp timing improvements should reduce the CPU usage
176 of the ortp receiver.
177 - improved audio grabbing. The 'grab' command of para_audiod
178 has its own set of command line options. Read the output of
179 "para_audioc help grab" for more info.
180 - oggdec: configurable input prebuffer size.
181 - the new error subsystem gives better error diagnostics
182 and reduces code size.
183
184
185 -----------------------------------------
186 0.2.8 (2006-01-02) "dynamic accumulation"
187 -----------------------------------------
188
189 The new modular filter design and the para_play-hangs bugfix.
190
191 - new executable: para_filter. It combines para_mp3dec,
192 para_oggdec and para_compress. It also adds a further filter
193 type, wav, that just inserts a wave header at the desired point
194 of the filter chain. All 'piping' is done in-memory (i.e. no
195 read/write operations are used).
196 - para_play: fix a stupid bug that caused it to hang under
197 certain circumstances.
198
199
200 -------------------------------------------
201 0.2.7 (2006-12-27) "transparent invariance"
202 -------------------------------------------
203
204 Not many user-visible changes but a fair amount of internal improvements.
205
206
207 - The http sender buffers data if it can not be sent
208 out immediately (because the socket is not writable). This
209 should prevent para_server from shutting down the connection
210 too early on a loaded network.
211 - para_play also prebuffers data if it is told to start at a
212 future time by the --start_time option.
213 - The return of para_recv: It combines para_ortp_recv and
214 para_http_recv. Use the --receiver option to switch between
215 the two. para_recv builds without libortp, but contains
216 only the http receiver in this case.
217 - update to ortp 0.8.1. As this ortp release contains incompatible
218 changes, para_recv-0.2.7 won't link against older ortp libs.
219 - improved ortp timings.
220 - use of gcc-extensions that #define away for non-gcc and
221 gcc < 3.0.
222
223
224 -------------------------------------------
225 0.2.6 (2005-10-29) "recursive compensation"
226 -------------------------------------------
227
228 Transparent session encryption (uses openssl's Alleged RC4 cipher),
229 the internal find command and several other improvements and cleanups.
230
231 - Encrypt the session if encryption is requested by the client
232 (default for para_client 0.2.6). This is backwards
233 compatible, so older clients can still connect to para_server
234 0.2.6. Use the new client option --plain to request an
235 uncrypted session (off by default, must be set to on in
236 order to connect to para_server 0.2.x with 0 <= x <= 5).
237 - para_server uses an internal function to locate audio files
238 rather than calling find(1). The server option
239 --mysql_audio_file_dir replaces --mysql_find_cmd.
240 - documentation update
241 - man pages
242 - header file cleanup
243 - para_client code cleanup
244 - para_gui: faster display of output of display commands
245
246
247 ------------------------------------------
248 0.2.5 (2005-10-13) "aggressive_resolution"
249 ------------------------------------------
250
251 This release adds internal senders, i.e. no more external programs are
252 spawned for sending out the audio data. There are two different senders
253 available: The http sender and the ortp sender (former para_send which
254 is no longer needed).
255
256 The new sender code has a plugin-like design so it can be easily
257 extended should there be be any future need for supporting another
258 network streaming protocol. All senders are completely independent of
259 each other. In particular, the http and the ortp sender can operate
260 in parallel.
261
262 - new server command: sender to control senders at runtime.
263 Read the output of "para_server -h" and "para_client help
264 sender" for more information.
265 - para_recv renamed to para_ortp_recv
266 - new executable: para_http_recv, a simple command line
267 http receiver.
268 - major afs/mp3/ogg code simplifications due to internal
269 senders.
270 - ogg timing improvements
271 - fix several minor memory leaks (found by valgrind)
272 - empty stream definitions work again
273 - com_ne(): ignore errors on remove
274 - audiod: fix segfault on server restart
275
276
277 ---------------------------------------
278 0.2.4 (2005-09-21) "toxic anticipation"
279 ---------------------------------------
280
281 Several small improvements, fixes and the new grab command.
282
283 - audiod:
284 - new command: "grab" to grab the output of the stream reader
285 or any filters. Read the output of "para_audioc help grab"
286 for more information.
287 - fix memory leak
288 - code cleanup
289 - audioc: new command line option: --bufsize to specify a
290 buffer size different from the default size 8192.
291 - improved error diagnostics for para_play.
292 - new configure option: --enable-ssldir so search for openssl in
293 non-standard places
294 - sdl_gui: Make it look nice again for 1024x768
295 - server: report total size of memory allocated with sbrk by malloc,
296 new command line option: --announce_time
297
298
299 -----------------------------------------
300 0.2.3 (2005-09-01) "hydrophilic movement"
301 -----------------------------------------
302
303 Two new executables and major feature enhancements.
304
305 - audiod filters: It is now possible to specify arbitrary many
306 (including none) filters for each supported audio
307 format. This can be used e.g. for normalizing volume,
308 transforming or grabbing the audio stream, or for using
309 visualizers. Read the output of "para_audiod -h" for the
310 syntax of the new --filter_cmd option.
311 - new executable: para_play, a tiny alsa player. It
312 can play wave files or raw pcm (16 bit little endian)
313 from stdin.
314 - new executable: para_compress, a dynamic range compressor
315 intended to keep audio output at a consistent volume. Derived
316 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
317 - audiod: New option: --stream_delay. This can be used in
318 a local network to syncronize the audio output of all
319 clients that play the same stream.
320
321
322 ------------------------------------------
323 0.2.2 (2005-08-19) "tangential excitation"
324 ------------------------------------------
325
326 Mostly internal changes in this release, but also some new commands
327 for the mysql database tool.
328
329 - cleanup exec.c, fix para_exec bug
330 - compile time loglevel (log messages below the given level
331 won't be compiled in, which reduces the size of the
332 resulting binaries)
333 - new log macros that shorten the size of the source code.
334 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
335 to send only zeros. With this workaround, para_audioc works
336 again.
337 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
338 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
339 (new entry), "snp" (set numplayed). Read the manual for more
340 information.
341
342
343 ---------------------------------------
344 0.2.1 (2005-08-15) "surreal experience"
345 ---------------------------------------
346
347 Here comes paraslash-0.2.1. It contains a couple of new features and,
348 surprise, only minor bug fixes.
349
350 - kill noisy mp3 debug message
351 - cleanup of the build system
352 - para_server and para_client directly use the crypto routines
353 of the openssl library rather than invoking the openssl command
354 line utitlity
355 - server/audiod: new option --user to switch to the given user
356 when invoked as root. Read the output of "para_server -h" for
357 more information.
358 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
359 status. Default: "para_audioc stat"
360 - sdl_gui: new option --pic_cmd to be used to download the picture.
361 Default: "para_client pic"
362 - audiod: 5 slots ought to be enough for everybody
363 - audiod: new status item: Uptime, kill hup command
364
365
366
367 ------------------------------------------
368 0.2.0 (2005-08-06) "distributed diffusion"
369 ------------------------------------------
370
371 After several month of increased development activity, paraslash-0.2.0
372 has arrived. It contains many new features and is much more
373 self-contained than the old 0.1.x series. Enjoy!
374
375
376 - para_server: fix hang on song change and crash on sighup.
377 Speed up mysql queries. The DIR_LIKE macro is gone.
378 - new executables: para_audiod, the local audio daemon that
379 starts playback (uses SCM_CREDENTIALS socket magic) and
380 para_audioc, the corresponding client.
381 - new executables: para_mp3dec/para_oggdec, two really teensy
382 decoders. para_mp3dec is based on libmad, para_oggdec requires
383 libvorbisfile.
384 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
385 they are now called para_send and para_recv respectively.
386 - documentation updates
387 - para_gui is themable. For now there is the default theme that
388 looks as before and the simple theme: blue and easy.
389 - gui: audio streaming is now handled by audiod. Time display shows
390 playback time rather than streaming time
391 - slider: update to libzmw-0.2.0
392 - para_krell: fix crash on server shutdown
393 - switch from gzip to bzip2
394
395
396 ----------------------------------------
397 0.1.7 (2005-04-18) "melting penetration"
398 ----------------------------------------
399
400 The main change in this release is clearly the oggvorbis rewrite,
401 but there are also lots of smaller changes. If you intend to use both
402 the mp3 and the ogg plugin, it is recommended to use software mixing,
403 e.g. the dmix plugin which is provided by ALSA.
404
405 - new executables: para_ovsend and para_ovrecv for sending/receiving
406 oggvorbis files via rtp. Requires the open rtp library. Get it at
407 http://www.linphone.org/ortp/
408 - rewrite of the ogg_vorbis core code
409 - configure detects libzmw and, if detected, includes
410 para_slider to the list of binaries to be built by make
411 - server stream writers read from their associated fifo rather
412 than from stdin
413 - slider: two new sliders, lastplayed and numplayed
414 - fix nasty double free bug which caused random segfaults in case of
415 mp3 files with invalid header information
416 - gui: new command line option: --stream_timeout=seconds to
417 deactivate a slot if it is idle for that many seconds (default=`5')
418 - diffstats
419
420
421 ---------------------------------------
422 0.1.6 (2005-03-05) "asymptotic balance"
423 ---------------------------------------
424
425 Only little user-visible changes in this release. Mainly bugfixes and
426 core code cleanup. This is probably the most stable version ever if you
427 stick to mp3...
428
429 - fix several memory leaks
430 - rename default name of mysql database from "music" to "paraslash".
431 Use para_server's --mysql_database option if you do not want to
432 rename your old database.
433 - rework ogg vorbis code
434 - make update command work on mysql servers with LOCAL_INFILE
435 disabled
436 - gui: improved stream I/O (slots)
437 - simplified audio format API
438 - para_pob_ogg is gone
439
440 ------------------------------------
441 0.1.5 (2004-12-31) "opaque eternity"
442 ------------------------------------
443
444 Let's slide gently into the new year.
445
446 - new: para_slider (not built automatically, type "make
447 para_slider" to build). A toy for those who always felt that
448 creating stream definitions is difficult. See screenshots,
449 README and FEATURES for more info.
450 - improved signal handling. Fixes server segfault on SIGHUP
451 for linux kernels newer than Aug 24 2004 and makes para_gui
452 race-free.
453 - reload database tool on SIGHUP
454 - improved help message for sl
455 - do not log "broken pipe" messages as errors. They are
456 perfectly ok.
457 - fix wrong error message on permission errors
458
459 -----------------------------------------
460 0.1.4 (2004-12-19) "tunneling transition"
461 -----------------------------------------
462
463 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
464 Hopefully, most of them got wiped out with this release. Some
465 enhancements went also in.
466
467 - improved error diagnostics for all commands
468 - stradd/picadd: overwrite previous contents if entry already
469 exists, rather than returning errors
470 - stradd: use current stream if invoked without args
471 - faster (and hopefully more stable) ogg-vorbis handling
472 - para_krell: reap children to avoid zombie-flooding in case
473 no server is running
474 - si: report also server pid
475 - server: don't busy-loop if dbtool reports only invalid files.
476 - gui: CTRL+C works again, fix stream_read command line option
477 - fix pic_add, hist
478 - fix mysql dbtool startup in case no database exists
479 - many small fixes and cleanups
480
481 ---------------------------------------
482 0.1.3: (2004-12-10) "vanishing inertia"
483 ---------------------------------------
484
485 Starting from this release, the database tools are integrated in the
486 server binary. This decreases server startup time, reduces code size
487 and speeds up database commands. However, the layout of the underlying
488 mysql database changed only slightly and 0.1.3 should be backwards
489 compatible in that respect.
490
491 Visible changes:
492
493 - If mysql is not detected at compile time, or fails to init
494 at runtime, fall back to the dopey database tool which should
495 always work.
496 - para_dbtool and dbtool.conf are gone. All mysql specific
497 options are read from server.conf and are prefixed by 'mysql_'.
498 - new command: cdt (change database tool)
499 - new command line option: dbtool (choose startup database tool)
500 - The name of current stream is now stored in the database,
501 so paraslash remembers its current stream when restarted.
502 - new command: csp (change stream and play)
503 - para_gui also reports current database tool and server uptime
504
505
506 -------------------------------------------
507 0.1.2: (2004-11-28) "spherical fluctuation"
508 -------------------------------------------
509
510 Point release before the big dbtool changes go in.
511
512 - dbtool: rename ca to cam (copy all meta data). It now also
513 copies numplayed and lastplayed time as well as the picture
514 id.
515 - fix endless-loop-bug caused by mp3 files with invalid header
516
517 -----------------------------------------
518 0.1.1: (2004-11-05) "floating atmosphere"
519 -----------------------------------------
520
521 - gkrellm plugin
522 - new dbtool command: mbox. Browse your sound-file collection
523 with your favorite mail reader.
524 - several small fixes
525
526 -------------------------------------
527 0.1.0: (2204-10-22) "rotating cortex"
528 -------------------------------------
529
530 - fix logging bug for loglevel > VERBOSE
531 - fix skip command
532 - correct timings for vbr mp3s
533 - modular audio format support
534 - ogg-vorbis support (experimental)
535 - new server option: autoplay
536
537 -----------------------------------------
538 0.0.99: (2004-07-25) "harmonic deviation"
539 -----------------------------------------
540
541 - rename projectname from icc to paraslash (play, archive, rate
542 and stream large audio sets happily)
543 - paraslash is no longer restricted to one particular audio
544 streaming software
