5 0.2.15 (to be announced) "inductive resonance"
6 ----------------------------------------------
7
8 Minor improvements, more documentation and a bunch of bug fixes.
9
10 - para_server: The server.users file is only read once on server
11 startup rather than for each connection
12 - mp3dec: Fix decoding of corrupt mp3 files
13 - afs (audio file sender) is now called vss (virtual streaming
14 system). Consequently, the permission flags specified in
15 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
16 become VSS_READ and VSS_WRITE respectively.
17 - para_audiod/para_filter: Fix a bug that caused the last chunk
18 of audio data not being written under certain circumstances
19 - audiod: compute the difference of server time and local time
20 correctly
21 - documentation improvements
22 - configure.ac: fix checks for para_krell
23 - new man pages
24
25 -------------------------------------------
26 0.2.14 (2006-10-15) "transient singularity"
27 -------------------------------------------
28
29 The only major enhancement of this version is the osx writer which completes
30 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
31 until now for reasons beyond the scope of this changelog entry.
32
33 - new output plugin for Mac Os: the osx writer
34 - rename configure command line options from --enable-xxx-headers to
35 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
36 - configure: new command line options: --with-mad-headers,
37 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
38 - some robustness fixes
39 - dymamic audio format recognition for audiod
40 - para_server: new command line option: --autoplay_delay
41 - para_audiod: new command line option: --clock_diff_count
42
43 ---------------------------------------
44 0.2.13 (2006-07-14) "sonic convolution"
45 ---------------------------------------
46
47 A bunch of new features and core changes.
48
49 - the new paraslash scheduler, short and sweet.
50 - Support for m4a/mp4 files via the new aac audio format
51 handler/filter (requires libfaad).
52 - each writer has its own command line parser, just like
53 para_recv and para_filter.
54 - para_client and para_audioc use the error subsystem
55 - writers are integrated in para_audiod (currently linux-only)
56 - para_client is integrated in para_audiod
57 - random/playlist selector: improved info strings
58 - new audiod commands: tasks, kill
59 - update to libortp-0.10.1
60 - para_fade: wake time defaults to 8 hours from now
61 - update to autoconf-2.60
62
63
64 ------------------------------------------
65 0.2.12 (2006-05-12) "oriented abstraction"
66 ------------------------------------------
67
68 Many user-visible changes in this release and lots of new
69 features:
70
71
72 - the new optional dccp sender/receiver. It uses the datagram
73 congestion control protocol. You'll need a fairly new kernel
74 for this.
75 - paraslash works on Mac OS X (thanks to Gerd Becker)
76 - para_play renamed to para_write
77 - modular output plugin design (writers) for para_write
78 - new file_writer output plugin for para_write
79 - compress filter speed improvements
80 - update to libortp-0.9.1
81 - update to gengetopt-2.17rc
82 - para_client no longer depends on libreadline (as the
83 code for the interactive mode was removed).
84 - gcc-2-95 is no longer a supported compiler. It may still
85 work, but it gets no more testing.
86 - the tarball no longer contains the screenshot images which
87 reduces its size quite a bit.
88 - configure: new command line options: --enable-mysql-headers
89 and --enable-mysql-libs
90
91 ------------------------------------
92 0.2.11 (2006-03-11) "atomic duality"
93 ------------------------------------
94
95 Here it is, the first paraslash release developed with git. There
96 are fairly many user-visible changes in this release. As two out of
97 the three "database tools" of paraslash don't use a database at all,
98 they are now called "audio file selectors" instead.
99
100
101 - the cdt command (change database tool) becomes chs (change
102 selector)
103 - no more colon separators: The syntax of some options of
104 para_audiod and para_filter have changed. Use --help for
105 more info (and some examples).
106 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
107 - switch from cvs to git (should've done that earlier)
108 - the new ipc subsystem
109 - new audio file selector: playlist
110 - para_server: the dopey selector is now called "random",
111 and is the default selector. Use the --selector option to
112 choose another selector at startup, or the chs command to
113 change the selector at runtime.
114 - X86_64 fixes (thanks to Steffen Klassert)
115 - para_play fixes
116
117
118 --------------------------------------
119 0.2.10 (2006-02-17) "cyclic attractor"
120 --------------------------------------
121
122 Huge documentation update, a scrollable window for para_gui, ortp
123 improvements, and of course many small fixes not mentioned here.
124 The diffstat below is rather misleading as most insertions are due
125 to the new source documentation.
126
127 - autoconf cleanup
128 - para_server also uses the new error subsystem
129 - lots of new documentation (UTSL)
130 - gui improvements:
131 - keysyms for cursor keys and for next/previous page keys
132 - scrollable output window
133 - new internal commands: scroll up/down, page up/down
134 - fix color of command output.
135 - ortp: the --chunk_time and --header flags are no longer needed
136 for para_recv/para_audiod as this information is now encoded in
137 each rtp packet sent by para_server.
138
139
140 -------------------------------------------
141 0.2.9 (2006-01-24) "progressive turbulence"
142 -------------------------------------------
143
144 Internal audiod receivers/filters, the new error subsystem and
145 a lot of small improvements.
146
147 - para_recv and para_filter are integrated into the para_audiod
148 binary, i.e. audiod no longer spawns a new process for
149 each receiver/filter. As para_recv and para_filter might be
150 useful as standalone programs, they still get built (linked
151 against the same object files that are also used for audiod).
152 - further ortp timing improvements should reduce the CPU usage
153 of the ortp receiver.
154 - improved audio grabbing. The 'grab' command of para_audiod
155 has its own set of command line options. Read the output of
156 "para_audioc help grab" for more info.
157 - oggdec: configurable input prebuffer size.
158 - the new error subsystem gives better error diagnostics
159 and reduces code size.
160
161
162 -----------------------------------------
163 0.2.8 (2006-01-02) "dynamic accumulation"
164 -----------------------------------------
165
166 The new modular filter design and the para_play-hangs bugfix.
167
168 - new executable: para_filter. It combines para_mp3dec,
169 para_oggdec and para_compress. It also adds a further filter
170 type, wav, that just inserts a wave header at the desired point
171 of the filter chain. All 'piping' is done in-memory (i.e. no
172 read/write operations are used).
173 - para_play: fix a stupid bug that caused it to hang under
174 certain circumstances.
175
176
177 -------------------------------------------
178 0.2.7 (2006-12-27) "transparent invariance"
179 -------------------------------------------
180
181 Not many user-visible changes but a fair amount of internal improvements.
182
183
184 - The http sender buffers data if it can not be sent
185 out immediately (because the socket is not writable). This
186 should prevent para_server from shutting down the connection
187 too early on a loaded network.
188 - para_play also prebuffers data if it is told to start at a
189 future time by the --start_time option.
190 - The return of para_recv: It combines para_ortp_recv and
191 para_http_recv. Use the --receiver option to switch between
192 the two. para_recv builds without libortp, but contains
193 only the http receiver in this case.
194 - update to ortp 0.8.1. As this ortp release contains incompatible
195 changes, para_recv-0.2.7 won't link against older ortp libs.
196 - improved ortp timings.
197 - use of gcc-extensions that #define away for non-gcc and
198 gcc < 3.0.
199
200
201 -------------------------------------------
202 0.2.6 (2005-10-29) "recursive compensation"
203 -------------------------------------------
204
205 Transparent session encryption (uses openssl's Alleged RC4 cipher),
206 the internal find command and several other improvements and cleanups.
207
208 - Encrypt the session if encryption is requested by the client
209 (default for para_client 0.2.6). This is backwards
210 compatible, so older clients can still connect to para_server
211 0.2.6. Use the new client option --plain to request an
212 uncrypted session (off by default, must be set to on in
213 order to connect to para_server 0.2.x with 0 <= x <= 5).
214 - para_server uses an internal function to locate audio files
215 rather than calling find(1). The server option
216 --mysql_audio_file_dir replaces --mysql_find_cmd.
217 - documentation update
218 - man pages
219 - header file cleanup
220 - para_client code cleanup
221 - para_gui: faster display of output of display commands
222
223
224 ------------------------------------------
225 0.2.5 (2005-10-13) "aggressive_resolution"
226 ------------------------------------------
227
228 This release adds internal senders, i.e. no more external programs are
229 spawned for sending out the audio data. There are two different senders
230 available: The http sender and the ortp sender (former para_send which
231 is no longer needed).
232
233 The new sender code has a plugin-like design so it can be easily
234 extended should there be be any future need for supporting another
235 network streaming protocol. All senders are completely independent of
236 each other. In particular, the http and the ortp sender can operate
237 in parallel.
238
239 - new server command: sender to control senders at runtime.
240 Read the output of "para_server -h" and "para_client help
241 sender" for more information.
242 - para_recv renamed to para_ortp_recv
243 - new executable: para_http_recv, a simple command line
244 http receiver.
245 - major afs/mp3/ogg code simplifications due to internal
246 senders.
247 - ogg timing improvements
248 - fix several minor memory leaks (found by valgrind)
249 - empty stream definitions work again
250 - com_ne(): ignore errors on remove
251 - audiod: fix segfault on server restart
252
253
254 ---------------------------------------
255 0.2.4 (2005-09-21) "toxic anticipation"
256 ---------------------------------------
257
258 Several small improvements, fixes and the new grab command.
259
260 - audiod:
261 - new command: "grab" to grab the output of the stream reader
262 or any filters. Read the output of "para_audioc help grab"
263 for more information.
264 - fix memory leak
265 - code cleanup
266 - audioc: new command line option: --bufsize to specify a
267 buffer size different from the default size 8192.
268 - improved error diagnostics for para_play.
269 - new configure option: --enable-ssldir so search for openssl in
270 non-standard places
271 - sdl_gui: Make it look nice again for 1024x768
272 - server: report total size of memory allocated with sbrk by malloc,
273 new command line option: --announce_time
274
275
276 -----------------------------------------
277 0.2.3 (2005-09-01) "hydrophilic movement"
278 -----------------------------------------
279
280 Two new executables and major feature enhancements.
281
282 - audiod filters: It is now possible to specify arbitrary many
283 (including none) filters for each supported audio
284 format. This can be used e.g. for normalizing volume,
285 transforming or grabbing the audio stream, or for using
286 visualizers. Read the output of "para_audiod -h" for the
287 syntax of the new --filter_cmd option.
288 - new executable: para_play, a tiny alsa player. It
289 can play wave files or raw pcm (16 bit little endian)
290 from stdin.
291 - new executable: para_compress, a dynamic range compressor
292 intended to keep audio output at a consistent volume. Derived
293 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
294 - audiod: New option: --stream_delay. This can be used in
295 a local network to syncronize the audio output of all
296 clients that play the same stream.
297
298
299 ------------------------------------------
300 0.2.2 (2005-08-19) "tangential excitation"
301 ------------------------------------------
302
303 Mostly internal changes in this release, but also some new commands
304 for the mysql database tool.
305
306 - cleanup exec.c, fix para_exec bug
307 - compile time loglevel (log messages below the given level
308 won't be compiled in, which reduces the size of the
309 resulting binaries)
310 - new log macros that shorten the size of the source code.
311 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
312 to send only zeros. With this workaround, para_audioc works
313 again.
314 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
315 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
316 (new entry), "snp" (set numplayed). Read the manual for more
317 information.
318
319
320 ---------------------------------------
321 0.2.1 (2005-08-15) "surreal experience"
322 ---------------------------------------
323
324 Here comes paraslash-0.2.1. It contains a couple of new features and,
325 surprise, only minor bug fixes.
326
327 - kill noisy mp3 debug message
328 - cleanup of the build system
329 - para_server and para_client directly use the crypto routines
330 of the openssl library rather than invoking the openssl command
331 line utitlity
332 - server/audiod: new option --user to switch to the given user
333 when invoked as root. Read the output of "para_server -h" for
334 more information.
335 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
336 status. Default: "para_audioc stat"
337 - sdl_gui: new option --pic_cmd to be used to download the picture.
338 Default: "para_client pic"
339 - audiod: 5 slots ought to be enough for everybody
340 - audiod: new status item: Uptime, kill hup command
341
342
343
344 ------------------------------------------
345 0.2.0 (2005-08-06) "distributed diffusion"
346 ------------------------------------------
347
348 After several month of increased development activity, paraslash-0.2.0
349 has arrived. It contains many new features and is much more
350 self-contained than the old 0.1.x series. Enjoy!
351
352
353 - para_server: fix hang on song change and crash on sighup.
354 Speed up mysql queries. The DIR_LIKE macro is gone.
355 - new executables: para_audiod, the local audio daemon that
356 starts playback (uses SCM_CREDENTIALS socket magic) and
357 para_audioc, the corresponding client.
358 - new executables: para_mp3dec/para_oggdec, two really teensy
359 decoders. para_mp3dec is based on libmad, para_oggdec requires
360 libvorbisfile.
361 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
362 they are now called para_send and para_recv respectively.
363 - documentation updates
364 - para_gui is themable. For now there is the default theme that
365 looks as before and the simple theme: blue and easy.
366 - gui: audio streaming is now handled by audiod. Time display shows
367 playback time rather than streaming time
368 - slider: update to libzmw-0.2.0
369 - para_krell: fix crash on server shutdown
370 - switch from gzip to bzip2
371
372
373 ----------------------------------------
374 0.1.7 (2005-04-18) "melting penetration"
375 ----------------------------------------
376
377 The main change in this release is clearly the oggvorbis rewrite,
378 but there are also lots of smaller changes. If you intend to use both
379 the mp3 and the ogg plugin, it is recommended to use software mixing,
380 e.g. the dmix plugin which is provided by ALSA.
381
382 - new executables: para_ovsend and para_ovrecv for sending/receiving
383 oggvorbis files via rtp. Requires the open rtp library. Get it at
384 http://www.linphone.org/ortp/
385 - rewrite of the ogg_vorbis core code
386 - configure detects libzmw and, if detected, includes
387 para_slider to the list of binaries to be built by make
388 - server stream writers read from their associated fifo rather
389 than from stdin
390 - slider: two new sliders, lastplayed and numplayed
391 - fix nasty double free bug which caused random segfaults in case of
392 mp3 files with invalid header information
393 - gui: new command line option: --stream_timeout=seconds to
394 deactivate a slot if it is idle for that many seconds (default=`5')
395 - diffstats
396
397
398 ---------------------------------------
399 0.1.6 (2005-03-05) "asymptotic balance"
400 ---------------------------------------
401
402 Only little user-visible changes in this release. Mainly bugfixes and
403 core code cleanup. This is probably the most stable version ever if you
404 stick to mp3...
405
406 - fix several memory leaks
407 - rename default name of mysql database from "music" to "paraslash".
408 Use para_server's --mysql_database option if you do not want to
409 rename your old database.
410 - rework ogg vorbis code
411 - make update command work on mysql servers with LOCAL_INFILE
412 disabled
413 - gui: improved stream I/O (slots)
414 - simplified audio format API
415 - para_pob_ogg is gone
416
417 ------------------------------------
418 0.1.5 (2004-12-31) "opaque eternity"
419 ------------------------------------
420
421 Let's slide gently into the new year.
422
423 - new: para_slider (not built automatically, type "make
424 para_slider" to build). A toy for those who always felt that
425 creating stream definitions is difficult. See screenshots,
426 README and FEATURES for more info.
427 - improved signal handling. Fixes server segfault on SIGHUP
428 for linux kernels newer than Aug 24 2004 and makes para_gui
429 race-free.
430 - reload database tool on SIGHUP
431 - improved help message for sl
432 - do not log "broken pipe" messages as errors. They are
433 perfectly ok.
434 - fix wrong error message on permission errors
435
436 -----------------------------------------
437 0.1.4 (2004-12-19) "tunneling transition"
438 -----------------------------------------
439
440 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
441 Hopefully, most of them got wiped out with this release. Some
442 enhancements went also in.
443
444 - improved error diagnostics for all commands
445 - stradd/picadd: overwrite previous contents if entry already
446 exists, rather than returning errors
447 - stradd: use current stream if invoked without args
448 - faster (and hopefully more stable) ogg-vorbis handling
449 - para_krell: reap children to avoid zombie-flooding in case
450 no server is running
451 - si: report also server pid
452 - server: don't busy-loop if dbtool reports only invalid files.
453 - gui: CTRL+C works again, fix stream_read command line option
454 - fix pic_add, hist
455 - fix mysql dbtool startup in case no database exists
456 - many small fixes and cleanups
457
458 ---------------------------------------
459 0.1.3: (2004-12-10) "vanishing inertia"
460 ---------------------------------------
461
462 Starting from this release, the database tools are integrated in the
463 server binary. This decreases server startup time, reduces code size
464 and speeds up database commands. However, the layout of the underlying
465 mysql database changed only slightly and 0.1.3 should be backwards
466 compatible in that respect.
467
468 Visible changes:
469
470 - If mysql is not detected at compile time, or fails to init
471 at runtime, fall back to the dopey database tool which should
472 always work.
473 - para_dbtool and dbtool.conf are gone. All mysql specific
474 options are read from server.conf and are prefixed by 'mysql_'.
475 - new command: cdt (change database tool)
476 - new command line option: dbtool (choose startup database tool)
477 - The name of current stream is now stored in the database,
478 so paraslash remembers its current stream when restarted.
479 - new command: csp (change stream and play)
480 - para_gui also reports current database tool and server uptime
481
482
483 -------------------------------------------
484 0.1.2: (2004-11-28) "spherical fluctuation"
485 -------------------------------------------
486
487 Point release before the big dbtool changes go in.
488
489 - dbtool: rename ca to cam (copy all meta data). It now also
490 copies numplayed and lastplayed time as well as the picture
491 id.
492 - fix endless-loop-bug caused by mp3 files with invalid header
493
494 -----------------------------------------
495 0.1.1: (2004-11-05) "floating atmosphere"
496 -----------------------------------------
497
498 - gkrellm plugin
499 - new dbtool command: mbox. Browse your sound-file collection
500 with your favorite mail reader.
501 - several small fixes
502
503 -------------------------------------
504 0.1.0: (2204-10-22) "rotating cortex"
505 -------------------------------------
506
507 - fix logging bug for loglevel > VERBOSE
508 - fix skip command
509 - correct timings for vbr mp3s
510 - modular audio format support
511 - ogg-vorbis support (experimental)
512 - new server option: autoplay
513
514 -----------------------------------------
515 0.0.99: (2004-07-25) "harmonic deviation"
516 -----------------------------------------
517
518 - rename projectname from icc to paraslash (play, archive, rate
519 and stream large audio sets happily)
520 - paraslash is no longer restricted to one particular audio
521 streaming software
522 - new dbtool commands (stradd, strq, strdel) for easy stream
523 managment w/o configuration file. That obsoletes stream_defs
524 file/config option for dbtool.
525 - picadd accepts jpeg data from stdin
526 - new server commands: ps (select previous stream), sc (song change)
527 - new default pictures for sdl_gui
528 - gui: new key_map option for binding commands and internal
529 functions to arbitrary keys, nice help screen, rip out
530 soundcard/linux specific stuff, avoid noise artefacts while jumping,
531 show silly logo on startup
532 - new executables: para_fade for fading volume, para_dbadm for
533 manipulating attributes
534 - cdb adds _all_ tables to mysql database
535 - revised and beautified documentation
536 - sample dbtool rewritten in C
537 - autoconf
538
539 ---------------------------------------------
540 0.0.98: (2003-12-26) "incremental smoothness"
541 ---------------------------------------------
542
543 - kick icecast in favour of poc. That removes some races and reduces
544 core code considerably.
545 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
