9 0.2.15 (2007-02-16) "inductive resonance"
10 -----------------------------------------
11
12 Minor improvements, more documentation and a bunch of bug fixes.
13
14 - para_server: The server.users file is only read once on server
15 startup rather than for each connection
16 - mp3dec: Fix decoding of corrupt mp3 files
17 - afs (audio file sender) is now called vss (virtual streaming
18 system). Consequently, the permission flags specified in
19 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
20 become VSS_READ and VSS_WRITE respectively.
21 - para_audiod/para_filter: Fix a bug that caused the last chunk
22 of audio data not being written under certain circumstances
23 - audiod: compute the difference of server time and local time
24 correctly
25 - para_server/para_audiod: Fix some memory leaks
26 - documentation improvements
27 - configure.ac: fix checks for para_krell
28 - new man pages
29
30 -------------------------------------------
31 0.2.14 (2006-10-15) "transient singularity"
32 -------------------------------------------
33
34 The only major enhancement of this version is the osx writer which completes
35 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
36 until now for reasons beyond the scope of this changelog entry.
37
38 - new output plugin for Mac Os: the osx writer
39 - rename configure command line options from --enable-xxx-headers to
40 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
41 - configure: new command line options: --with-mad-headers,
42 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
43 - some robustness fixes
44 - dymamic audio format recognition for audiod
45 - para_server: new command line option: --autoplay_delay
46 - para_audiod: new command line option: --clock_diff_count
47
48 ---------------------------------------
49 0.2.13 (2006-07-14) "sonic convolution"
50 ---------------------------------------
51
52 A bunch of new features and core changes.
53
54 - the new paraslash scheduler, short and sweet.
55 - Support for m4a/mp4 files via the new aac audio format
56 handler/filter (requires libfaad).
57 - each writer has its own command line parser, just like
58 para_recv and para_filter.
59 - para_client and para_audioc use the error subsystem
60 - writers are integrated in para_audiod (currently linux-only)
61 - para_client is integrated in para_audiod
62 - random/playlist selector: improved info strings
63 - new audiod commands: tasks, kill
64 - update to libortp-0.10.1
65 - para_fade: wake time defaults to 8 hours from now
66 - update to autoconf-2.60
67
68
69 ------------------------------------------
70 0.2.12 (2006-05-12) "oriented abstraction"
71 ------------------------------------------
72
73 Many user-visible changes in this release and lots of new
74 features:
75
76
77 - the new optional dccp sender/receiver. It uses the datagram
78 congestion control protocol. You'll need a fairly new kernel
79 for this.
80 - paraslash works on Mac OS X (thanks to Gerd Becker)
81 - para_play renamed to para_write
82 - modular output plugin design (writers) for para_write
83 - new file_writer output plugin for para_write
84 - compress filter speed improvements
85 - update to libortp-0.9.1
86 - update to gengetopt-2.17rc
87 - para_client no longer depends on libreadline (as the
88 code for the interactive mode was removed).
89 - gcc-2-95 is no longer a supported compiler. It may still
90 work, but it gets no more testing.
91 - the tarball no longer contains the screenshot images which
92 reduces its size quite a bit.
93 - configure: new command line options: --enable-mysql-headers
94 and --enable-mysql-libs
95
96 ------------------------------------
97 0.2.11 (2006-03-11) "atomic duality"
98 ------------------------------------
99
100 Here it is, the first paraslash release developed with git. There
101 are fairly many user-visible changes in this release. As two out of
102 the three "database tools" of paraslash don't use a database at all,
103 they are now called "audio file selectors" instead.
104
105
106 - the cdt command (change database tool) becomes chs (change
107 selector)
108 - no more colon separators: The syntax of some options of
109 para_audiod and para_filter have changed. Use --help for
110 more info (and some examples).
111 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
112 - switch from cvs to git (should've done that earlier)
113 - the new ipc subsystem
114 - new audio file selector: playlist
115 - para_server: the dopey selector is now called "random",
116 and is the default selector. Use the --selector option to
117 choose another selector at startup, or the chs command to
118 change the selector at runtime.
119 - X86_64 fixes (thanks to Steffen Klassert)
120 - para_play fixes
121
122
123 --------------------------------------
124 0.2.10 (2006-02-17) "cyclic attractor"
125 --------------------------------------
126
127 Huge documentation update, a scrollable window for para_gui, ortp
128 improvements, and of course many small fixes not mentioned here.
129 The diffstat below is rather misleading as most insertions are due
130 to the new source documentation.
131
132 - autoconf cleanup
133 - para_server also uses the new error subsystem
134 - lots of new documentation (UTSL)
135 - gui improvements:
136 - keysyms for cursor keys and for next/previous page keys
137 - scrollable output window
138 - new internal commands: scroll up/down, page up/down
139 - fix color of command output.
140 - ortp: the --chunk_time and --header flags are no longer needed
141 for para_recv/para_audiod as this information is now encoded in
142 each rtp packet sent by para_server.
143
144
145 -------------------------------------------
146 0.2.9 (2006-01-24) "progressive turbulence"
147 -------------------------------------------
148
149 Internal audiod receivers/filters, the new error subsystem and
150 a lot of small improvements.
151
152 - para_recv and para_filter are integrated into the para_audiod
153 binary, i.e. audiod no longer spawns a new process for
154 each receiver/filter. As para_recv and para_filter might be
155 useful as standalone programs, they still get built (linked
156 against the same object files that are also used for audiod).
157 - further ortp timing improvements should reduce the CPU usage
158 of the ortp receiver.
159 - improved audio grabbing. The 'grab' command of para_audiod
160 has its own set of command line options. Read the output of
161 "para_audioc help grab" for more info.
162 - oggdec: configurable input prebuffer size.
163 - the new error subsystem gives better error diagnostics
164 and reduces code size.
165
166
167 -----------------------------------------
168 0.2.8 (2006-01-02) "dynamic accumulation"
169 -----------------------------------------
170
171 The new modular filter design and the para_play-hangs bugfix.
172
173 - new executable: para_filter. It combines para_mp3dec,
174 para_oggdec and para_compress. It also adds a further filter
175 type, wav, that just inserts a wave header at the desired point
176 of the filter chain. All 'piping' is done in-memory (i.e. no
177 read/write operations are used).
178 - para_play: fix a stupid bug that caused it to hang under
179 certain circumstances.
180
181
182 -------------------------------------------
183 0.2.7 (2006-12-27) "transparent invariance"
184 -------------------------------------------
185
186 Not many user-visible changes but a fair amount of internal improvements.
187
188
189 - The http sender buffers data if it can not be sent
190 out immediately (because the socket is not writable). This
191 should prevent para_server from shutting down the connection
192 too early on a loaded network.
193 - para_play also prebuffers data if it is told to start at a
194 future time by the --start_time option.
195 - The return of para_recv: It combines para_ortp_recv and
196 para_http_recv. Use the --receiver option to switch between
197 the two. para_recv builds without libortp, but contains
198 only the http receiver in this case.
199 - update to ortp 0.8.1. As this ortp release contains incompatible
200 changes, para_recv-0.2.7 won't link against older ortp libs.
201 - improved ortp timings.
202 - use of gcc-extensions that #define away for non-gcc and
203 gcc < 3.0.
204
205
206 -------------------------------------------
207 0.2.6 (2005-10-29) "recursive compensation"
208 -------------------------------------------
209
210 Transparent session encryption (uses openssl's Alleged RC4 cipher),
211 the internal find command and several other improvements and cleanups.
212
213 - Encrypt the session if encryption is requested by the client
214 (default for para_client 0.2.6). This is backwards
215 compatible, so older clients can still connect to para_server
216 0.2.6. Use the new client option --plain to request an
217 uncrypted session (off by default, must be set to on in
218 order to connect to para_server 0.2.x with 0 <= x <= 5).
219 - para_server uses an internal function to locate audio files
220 rather than calling find(1). The server option
221 --mysql_audio_file_dir replaces --mysql_find_cmd.
222 - documentation update
223 - man pages
224 - header file cleanup
225 - para_client code cleanup
226 - para_gui: faster display of output of display commands
227
228
229 ------------------------------------------
230 0.2.5 (2005-10-13) "aggressive_resolution"
231 ------------------------------------------
232
233 This release adds internal senders, i.e. no more external programs are
234 spawned for sending out the audio data. There are two different senders
235 available: The http sender and the ortp sender (former para_send which
236 is no longer needed).
237
238 The new sender code has a plugin-like design so it can be easily
239 extended should there be be any future need for supporting another
240 network streaming protocol. All senders are completely independent of
241 each other. In particular, the http and the ortp sender can operate
242 in parallel.
243
244 - new server command: sender to control senders at runtime.
245 Read the output of "para_server -h" and "para_client help
246 sender" for more information.
247 - para_recv renamed to para_ortp_recv
248 - new executable: para_http_recv, a simple command line
249 http receiver.
250 - major afs/mp3/ogg code simplifications due to internal
251 senders.
252 - ogg timing improvements
253 - fix several minor memory leaks (found by valgrind)
254 - empty stream definitions work again
255 - com_ne(): ignore errors on remove
256 - audiod: fix segfault on server restart
257
258
259 ---------------------------------------
260 0.2.4 (2005-09-21) "toxic anticipation"
261 ---------------------------------------
262
263 Several small improvements, fixes and the new grab command.
264
265 - audiod:
266 - new command: "grab" to grab the output of the stream reader
267 or any filters. Read the output of "para_audioc help grab"
268 for more information.
269 - fix memory leak
270 - code cleanup
271 - audioc: new command line option: --bufsize to specify a
272 buffer size different from the default size 8192.
273 - improved error diagnostics for para_play.
274 - new configure option: --enable-ssldir so search for openssl in
275 non-standard places
276 - sdl_gui: Make it look nice again for 1024x768
277 - server: report total size of memory allocated with sbrk by malloc,
278 new command line option: --announce_time
279
280
281 -----------------------------------------
282 0.2.3 (2005-09-01) "hydrophilic movement"
283 -----------------------------------------
284
285 Two new executables and major feature enhancements.
286
287 - audiod filters: It is now possible to specify arbitrary many
288 (including none) filters for each supported audio
289 format. This can be used e.g. for normalizing volume,
290 transforming or grabbing the audio stream, or for using
291 visualizers. Read the output of "para_audiod -h" for the
292 syntax of the new --filter_cmd option.
293 - new executable: para_play, a tiny alsa player. It
294 can play wave files or raw pcm (16 bit little endian)
295 from stdin.
296 - new executable: para_compress, a dynamic range compressor
297 intended to keep audio output at a consistent volume. Derived
298 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
299 - audiod: New option: --stream_delay. This can be used in
300 a local network to syncronize the audio output of all
301 clients that play the same stream.
302
303
304 ------------------------------------------
305 0.2.2 (2005-08-19) "tangential excitation"
306 ------------------------------------------
307
308 Mostly internal changes in this release, but also some new commands
309 for the mysql database tool.
310
311 - cleanup exec.c, fix para_exec bug
312 - compile time loglevel (log messages below the given level
313 won't be compiled in, which reduces the size of the
314 resulting binaries)
315 - new log macros that shorten the size of the source code.
316 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
317 to send only zeros. With this workaround, para_audioc works
318 again.
319 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
320 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
321 (new entry), "snp" (set numplayed). Read the manual for more
322 information.
323
324
325 ---------------------------------------
326 0.2.1 (2005-08-15) "surreal experience"
327 ---------------------------------------
328
329 Here comes paraslash-0.2.1. It contains a couple of new features and,
330 surprise, only minor bug fixes.
331
332 - kill noisy mp3 debug message
333 - cleanup of the build system
334 - para_server and para_client directly use the crypto routines
335 of the openssl library rather than invoking the openssl command
336 line utitlity
337 - server/audiod: new option --user to switch to the given user
338 when invoked as root. Read the output of "para_server -h" for
339 more information.
340 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
341 status. Default: "para_audioc stat"
342 - sdl_gui: new option --pic_cmd to be used to download the picture.
343 Default: "para_client pic"
344 - audiod: 5 slots ought to be enough for everybody
345 - audiod: new status item: Uptime, kill hup command
346
347
348
349 ------------------------------------------
350 0.2.0 (2005-08-06) "distributed diffusion"
351 ------------------------------------------
352
353 After several month of increased development activity, paraslash-0.2.0
354 has arrived. It contains many new features and is much more
355 self-contained than the old 0.1.x series. Enjoy!
356
357
358 - para_server: fix hang on song change and crash on sighup.
359 Speed up mysql queries. The DIR_LIKE macro is gone.
360 - new executables: para_audiod, the local audio daemon that
361 starts playback (uses SCM_CREDENTIALS socket magic) and
362 para_audioc, the corresponding client.
363 - new executables: para_mp3dec/para_oggdec, two really teensy
364 decoders. para_mp3dec is based on libmad, para_oggdec requires
365 libvorbisfile.
366 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
367 they are now called para_send and para_recv respectively.
368 - documentation updates
369 - para_gui is themable. For now there is the default theme that
370 looks as before and the simple theme: blue and easy.
371 - gui: audio streaming is now handled by audiod. Time display shows
372 playback time rather than streaming time
373 - slider: update to libzmw-0.2.0
374 - para_krell: fix crash on server shutdown
375 - switch from gzip to bzip2
376
377
378 ----------------------------------------
379 0.1.7 (2005-04-18) "melting penetration"
380 ----------------------------------------
381
382 The main change in this release is clearly the oggvorbis rewrite,
383 but there are also lots of smaller changes. If you intend to use both
384 the mp3 and the ogg plugin, it is recommended to use software mixing,
385 e.g. the dmix plugin which is provided by ALSA.
386
387 - new executables: para_ovsend and para_ovrecv for sending/receiving
388 oggvorbis files via rtp. Requires the open rtp library. Get it at
389 http://www.linphone.org/ortp/
390 - rewrite of the ogg_vorbis core code
391 - configure detects libzmw and, if detected, includes
392 para_slider to the list of binaries to be built by make
393 - server stream writers read from their associated fifo rather
394 than from stdin
395 - slider: two new sliders, lastplayed and numplayed
396 - fix nasty double free bug which caused random segfaults in case of
397 mp3 files with invalid header information
398 - gui: new command line option: --stream_timeout=seconds to
399 deactivate a slot if it is idle for that many seconds (default=`5')
400 - diffstats
401
402
403 ---------------------------------------
404 0.1.6 (2005-03-05) "asymptotic balance"
405 ---------------------------------------
406
407 Only little user-visible changes in this release. Mainly bugfixes and
408 core code cleanup. This is probably the most stable version ever if you
409 stick to mp3...
410
411 - fix several memory leaks
412 - rename default name of mysql database from "music" to "paraslash".
413 Use para_server's --mysql_database option if you do not want to
414 rename your old database.
415 - rework ogg vorbis code
416 - make update command work on mysql servers with LOCAL_INFILE
417 disabled
418 - gui: improved stream I/O (slots)
419 - simplified audio format API
420 - para_pob_ogg is gone
421
422 ------------------------------------
423 0.1.5 (2004-12-31) "opaque eternity"
424 ------------------------------------
425
426 Let's slide gently into the new year.
427
428 - new: para_slider (not built automatically, type "make
429 para_slider" to build). A toy for those who always felt that
430 creating stream definitions is difficult. See screenshots,
431 README and FEATURES for more info.
432 - improved signal handling. Fixes server segfault on SIGHUP
433 for linux kernels newer than Aug 24 2004 and makes para_gui
434 race-free.
435 - reload database tool on SIGHUP
436 - improved help message for sl
437 - do not log "broken pipe" messages as errors. They are
438 perfectly ok.
439 - fix wrong error message on permission errors
440
441 -----------------------------------------
442 0.1.4 (2004-12-19) "tunneling transition"
443 -----------------------------------------
444
445 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
446 Hopefully, most of them got wiped out with this release. Some
447 enhancements went also in.
448
449 - improved error diagnostics for all commands
450 - stradd/picadd: overwrite previous contents if entry already
451 exists, rather than returning errors
452 - stradd: use current stream if invoked without args
453 - faster (and hopefully more stable) ogg-vorbis handling
454 - para_krell: reap children to avoid zombie-flooding in case
455 no server is running
456 - si: report also server pid
457 - server: don't busy-loop if dbtool reports only invalid files.
458 - gui: CTRL+C works again, fix stream_read command line option
459 - fix pic_add, hist
460 - fix mysql dbtool startup in case no database exists
461 - many small fixes and cleanups
462
463 ---------------------------------------
464 0.1.3: (2004-12-10) "vanishing inertia"
465 ---------------------------------------
466
467 Starting from this release, the database tools are integrated in the
468 server binary. This decreases server startup time, reduces code size
469 and speeds up database commands. However, the layout of the underlying
470 mysql database changed only slightly and 0.1.3 should be backwards
471 compatible in that respect.
472
473 Visible changes:
474
475 - If mysql is not detected at compile time, or fails to init
476 at runtime, fall back to the dopey database tool which should
477 always work.
478 - para_dbtool and dbtool.conf are gone. All mysql specific
479 options are read from server.conf and are prefixed by 'mysql_'.
480 - new command: cdt (change database tool)
481 - new command line option: dbtool (choose startup database tool)
482 - The name of current stream is now stored in the database,
483 so paraslash remembers its current stream when restarted.
484 - new command: csp (change stream and play)
485 - para_gui also reports current database tool and server uptime
486
487
488 -------------------------------------------
489 0.1.2: (2004-11-28) "spherical fluctuation"
490 -------------------------------------------
491
492 Point release before the big dbtool changes go in.
493
494 - dbtool: rename ca to cam (copy all meta data). It now also
495 copies numplayed and lastplayed time as well as the picture
496 id.
497 - fix endless-loop-bug caused by mp3 files with invalid header
498
499 -----------------------------------------
500 0.1.1: (2004-11-05) "floating atmosphere"
501 -----------------------------------------
502
503 - gkrellm plugin
504 - new dbtool command: mbox. Browse your sound-file collection
505 with your favorite mail reader.
506 - several small fixes
507
508 -------------------------------------
509 0.1.0: (2204-10-22) "rotating cortex"
510 -------------------------------------
511
512 - fix logging bug for loglevel > VERBOSE
513 - fix skip command
514 - correct timings for vbr mp3s
515 - modular audio format support
516 - ogg-vorbis support (experimental)
517 - new server option: autoplay
518
519 -----------------------------------------
520 0.0.99: (2004-07-25) "harmonic deviation"
521 -----------------------------------------
522
523 - rename projectname from icc to paraslash (play, archive, rate
524 and stream large audio sets happily)
525 - paraslash is no longer restricted to one particular audio
526 streaming software
527 - new dbtool commands (stradd, strq, strdel) for easy stream
528 managment w/o configuration file. That obsoletes stream_defs
529 file/config option for dbtool.
530 - picadd accepts jpeg data from stdin
531 - new server commands: ps (select previous stream), sc (song change)
532 - new default pictures for sdl_gui
533 - gui: new key_map option for binding commands and internal
534 functions to arbitrary keys, nice help screen, rip out
535 soundcard/linux specific stuff, avoid noise artefacts while jumping,
536 show silly logo on startup
537 - new executables: para_fade for fading volume, para_dbadm for
538 manipulating attributes
539 - cdb adds _all_ tables to mysql database
540 - revised and beautified documentation
541 - sample dbtool rewritten in C
542 - autoconf
543
544 ---------------------------------------------
545 0.0.98: (2003-12-26) "incremental smoothness"
546 ---------------------------------------------
