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