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