4 ------------------------------------------
5 0.?.? (to be announced) "neural discharge"
6 ------------------------------------------
7
8 - fix a bug in para_filter that caused decoding of aac files
9 to start only after a few seconds.
10
11 -----------------------------------------
12 0.2.15 (2007-02-16) "inductive resonance"
13 -----------------------------------------
14
15 Minor improvements, more documentation and a bunch of bug fixes.
16
17 - para_server: The server.users file is only read once on server
18 startup rather than for each connection
19 - mp3dec: Fix decoding of corrupt mp3 files
20 - afs (audio file sender) is now called vss (virtual streaming
21 system). Consequently, the permission flags specified in
22 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
23 become VSS_READ and VSS_WRITE respectively.
24 - para_audiod/para_filter: Fix a bug that caused the last chunk
25 of audio data not being written under certain circumstances
26 - audiod: compute the difference of server time and local time
27 correctly
28 - para_server/para_audiod: Fix some memory leaks
29 - documentation improvements
30 - configure.ac: fix checks for para_krell
31 - new man pages
32
33 -------------------------------------------
34 0.2.14 (2006-10-15) "transient singularity"
35 -------------------------------------------
36
37 The only major enhancement of this version is the osx writer which completes
38 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
39 until now for reasons beyond the scope of this changelog entry.
40
41 - new output plugin for Mac Os: the osx writer
42 - rename configure command line options from --enable-xxx-headers to
43 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
44 - configure: new command line options: --with-mad-headers,
45 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
46 - some robustness fixes
47 - dymamic audio format recognition for audiod
48 - para_server: new command line option: --autoplay_delay
49 - para_audiod: new command line option: --clock_diff_count
50
51 ---------------------------------------
52 0.2.13 (2006-07-14) "sonic convolution"
53 ---------------------------------------
54
55 A bunch of new features and core changes.
56
57 - the new paraslash scheduler, short and sweet.
58 - Support for m4a/mp4 files via the new aac audio format
59 handler/filter (requires libfaad).
60 - each writer has its own command line parser, just like
61 para_recv and para_filter.
62 - para_client and para_audioc use the error subsystem
63 - writers are integrated in para_audiod (currently linux-only)
64 - para_client is integrated in para_audiod
65 - random/playlist selector: improved info strings
66 - new audiod commands: tasks, kill
67 - update to libortp-0.10.1
68 - para_fade: wake time defaults to 8 hours from now
69 - update to autoconf-2.60
70
71
72 ------------------------------------------
73 0.2.12 (2006-05-12) "oriented abstraction"
74 ------------------------------------------
75
76 Many user-visible changes in this release and lots of new
77 features:
78
79
80 - the new optional dccp sender/receiver. It uses the datagram
81 congestion control protocol. You'll need a fairly new kernel
82 for this.
83 - paraslash works on Mac OS X (thanks to Gerd Becker)
84 - para_play renamed to para_write
85 - modular output plugin design (writers) for para_write
86 - new file_writer output plugin for para_write
87 - compress filter speed improvements
88 - update to libortp-0.9.1
89 - update to gengetopt-2.17rc
90 - para_client no longer depends on libreadline (as the
91 code for the interactive mode was removed).
92 - gcc-2-95 is no longer a supported compiler. It may still
93 work, but it gets no more testing.
94 - the tarball no longer contains the screenshot images which
95 reduces its size quite a bit.
96 - configure: new command line options: --enable-mysql-headers
97 and --enable-mysql-libs
98
99 ------------------------------------
100 0.2.11 (2006-03-11) "atomic duality"
101 ------------------------------------
102
103 Here it is, the first paraslash release developed with git. There
104 are fairly many user-visible changes in this release. As two out of
105 the three "database tools" of paraslash don't use a database at all,
106 they are now called "audio file selectors" instead.
107
108
109 - the cdt command (change database tool) becomes chs (change
110 selector)
111 - no more colon separators: The syntax of some options of
112 para_audiod and para_filter have changed. Use --help for
113 more info (and some examples).
114 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
115 - switch from cvs to git (should've done that earlier)
116 - the new ipc subsystem
117 - new audio file selector: playlist
118 - para_server: the dopey selector is now called "random",
119 and is the default selector. Use the --selector option to
120 choose another selector at startup, or the chs command to
121 change the selector at runtime.
122 - X86_64 fixes (thanks to Steffen Klassert)
123 - para_play fixes
124
125
126 --------------------------------------
127 0.2.10 (2006-02-17) "cyclic attractor"
128 --------------------------------------
129
130 Huge documentation update, a scrollable window for para_gui, ortp
131 improvements, and of course many small fixes not mentioned here.
132 The diffstat below is rather misleading as most insertions are due
133 to the new source documentation.
134
135 - autoconf cleanup
136 - para_server also uses the new error subsystem
137 - lots of new documentation (UTSL)
138 - gui improvements:
139 - keysyms for cursor keys and for next/previous page keys
140 - scrollable output window
141 - new internal commands: scroll up/down, page up/down
142 - fix color of command output.
143 - ortp: the --chunk_time and --header flags are no longer needed
144 for para_recv/para_audiod as this information is now encoded in
145 each rtp packet sent by para_server.
146
147
148 -------------------------------------------
149 0.2.9 (2006-01-24) "progressive turbulence"
150 -------------------------------------------
151
152 Internal audiod receivers/filters, the new error subsystem and
153 a lot of small improvements.
154
155 - para_recv and para_filter are integrated into the para_audiod
156 binary, i.e. audiod no longer spawns a new process for
157 each receiver/filter. As para_recv and para_filter might be
158 useful as standalone programs, they still get built (linked
159 against the same object files that are also used for audiod).
160 - further ortp timing improvements should reduce the CPU usage
161 of the ortp receiver.
162 - improved audio grabbing. The 'grab' command of para_audiod
163 has its own set of command line options. Read the output of
164 "para_audioc help grab" for more info.
165 - oggdec: configurable input prebuffer size.
166 - the new error subsystem gives better error diagnostics
167 and reduces code size.
168
169
170 -----------------------------------------
171 0.2.8 (2006-01-02) "dynamic accumulation"
172 -----------------------------------------
173
174 The new modular filter design and the para_play-hangs bugfix.
175
176 - new executable: para_filter. It combines para_mp3dec,
177 para_oggdec and para_compress. It also adds a further filter
178 type, wav, that just inserts a wave header at the desired point
179 of the filter chain. All 'piping' is done in-memory (i.e. no
180 read/write operations are used).
181 - para_play: fix a stupid bug that caused it to hang under
182 certain circumstances.
183
184
185 -------------------------------------------
186 0.2.7 (2006-12-27) "transparent invariance"
187 -------------------------------------------
188
189 Not many user-visible changes but a fair amount of internal improvements.
190
191
192 - The http sender buffers data if it can not be sent
193 out immediately (because the socket is not writable). This
194 should prevent para_server from shutting down the connection
195 too early on a loaded network.
196 - para_play also prebuffers data if it is told to start at a
197 future time by the --start_time option.
198 - The return of para_recv: It combines para_ortp_recv and
199 para_http_recv. Use the --receiver option to switch between
200 the two. para_recv builds without libortp, but contains
201 only the http receiver in this case.
202 - update to ortp 0.8.1. As this ortp release contains incompatible
203 changes, para_recv-0.2.7 won't link against older ortp libs.
204 - improved ortp timings.
205 - use of gcc-extensions that #define away for non-gcc and
206 gcc < 3.0.
207
208
209 -------------------------------------------
210 0.2.6 (2005-10-29) "recursive compensation"
211 -------------------------------------------
212
213 Transparent session encryption (uses openssl's Alleged RC4 cipher),
214 the internal find command and several other improvements and cleanups.
215
216 - Encrypt the session if encryption is requested by the client
217 (default for para_client 0.2.6). This is backwards
218 compatible, so older clients can still connect to para_server
219 0.2.6. Use the new client option --plain to request an
220 uncrypted session (off by default, must be set to on in
221 order to connect to para_server 0.2.x with 0 <= x <= 5).
222 - para_server uses an internal function to locate audio files
223 rather than calling find(1). The server option
224 --mysql_audio_file_dir replaces --mysql_find_cmd.
225 - documentation update
226 - man pages
227 - header file cleanup
228 - para_client code cleanup
229 - para_gui: faster display of output of display commands
230
231
232 ------------------------------------------
233 0.2.5 (2005-10-13) "aggressive_resolution"
234 ------------------------------------------
235
236 This release adds internal senders, i.e. no more external programs are
237 spawned for sending out the audio data. There are two different senders
238 available: The http sender and the ortp sender (former para_send which
239 is no longer needed).
240
241 The new sender code has a plugin-like design so it can be easily
242 extended should there be be any future need for supporting another
243 network streaming protocol. All senders are completely independent of
244 each other. In particular, the http and the ortp sender can operate
245 in parallel.
246
247 - new server command: sender to control senders at runtime.
248 Read the output of "para_server -h" and "para_client help
249 sender" for more information.
250 - para_recv renamed to para_ortp_recv
251 - new executable: para_http_recv, a simple command line
252 http receiver.
253 - major afs/mp3/ogg code simplifications due to internal
254 senders.
255 - ogg timing improvements
256 - fix several minor memory leaks (found by valgrind)
257 - empty stream definitions work again
258 - com_ne(): ignore errors on remove
259 - audiod: fix segfault on server restart
260
261
262 ---------------------------------------
263 0.2.4 (2005-09-21) "toxic anticipation"
264 ---------------------------------------
265
266 Several small improvements, fixes and the new grab command.
267
268 - audiod:
269 - new command: "grab" to grab the output of the stream reader
270 or any filters. Read the output of "para_audioc help grab"
271 for more information.
272 - fix memory leak
273 - code cleanup
274 - audioc: new command line option: --bufsize to specify a
275 buffer size different from the default size 8192.
276 - improved error diagnostics for para_play.
277 - new configure option: --enable-ssldir so search for openssl in
278 non-standard places
279 - sdl_gui: Make it look nice again for 1024x768
280 - server: report total size of memory allocated with sbrk by malloc,
281 new command line option: --announce_time
282
283
284 -----------------------------------------
285 0.2.3 (2005-09-01) "hydrophilic movement"
286 -----------------------------------------
287
288 Two new executables and major feature enhancements.
289
290 - audiod filters: It is now possible to specify arbitrary many
291 (including none) filters for each supported audio
292 format. This can be used e.g. for normalizing volume,
293 transforming or grabbing the audio stream, or for using
294 visualizers. Read the output of "para_audiod -h" for the
295 syntax of the new --filter_cmd option.
296 - new executable: para_play, a tiny alsa player. It
297 can play wave files or raw pcm (16 bit little endian)
298 from stdin.
299 - new executable: para_compress, a dynamic range compressor
300 intended to keep audio output at a consistent volume. Derived
301 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
302 - audiod: New option: --stream_delay. This can be used in
303 a local network to syncronize the audio output of all
304 clients that play the same stream.
305
306
307 ------------------------------------------
308 0.2.2 (2005-08-19) "tangential excitation"
309 ------------------------------------------
310
311 Mostly internal changes in this release, but also some new commands
312 for the mysql database tool.
313
314 - cleanup exec.c, fix para_exec bug
315 - compile time loglevel (log messages below the given level
316 won't be compiled in, which reduces the size of the
317 resulting binaries)
318 - new log macros that shorten the size of the source code.
319 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
320 to send only zeros. With this workaround, para_audioc works
321 again.
322 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
323 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
324 (new entry), "snp" (set numplayed). Read the manual for more
325 information.
326
327
328 ---------------------------------------
329 0.2.1 (2005-08-15) "surreal experience"
330 ---------------------------------------
331
332 Here comes paraslash-0.2.1. It contains a couple of new features and,
333 surprise, only minor bug fixes.
334
335 - kill noisy mp3 debug message
336 - cleanup of the build system
337 - para_server and para_client directly use the crypto routines
338 of the openssl library rather than invoking the openssl command
339 line utitlity
340 - server/audiod: new option --user to switch to the given user
341 when invoked as root. Read the output of "para_server -h" for
342 more information.
343 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
344 status. Default: "para_audioc stat"
345 - sdl_gui: new option --pic_cmd to be used to download the picture.
346 Default: "para_client pic"
347 - audiod: 5 slots ought to be enough for everybody
348 - audiod: new status item: Uptime, kill hup command
349
350
351
352 ------------------------------------------
353 0.2.0 (2005-08-06) "distributed diffusion"
354 ------------------------------------------
355
356 After several month of increased development activity, paraslash-0.2.0
357 has arrived. It contains many new features and is much more
358 self-contained than the old 0.1.x series. Enjoy!
359
360
361 - para_server: fix hang on song change and crash on sighup.
362 Speed up mysql queries. The DIR_LIKE macro is gone.
363 - new executables: para_audiod, the local audio daemon that
364 starts playback (uses SCM_CREDENTIALS socket magic) and
365 para_audioc, the corresponding client.
366 - new executables: para_mp3dec/para_oggdec, two really teensy
367 decoders. para_mp3dec is based on libmad, para_oggdec requires
368 libvorbisfile.
369 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
370 they are now called para_send and para_recv respectively.
371 - documentation updates
372 - para_gui is themable. For now there is the default theme that
373 looks as before and the simple theme: blue and easy.
374 - gui: audio streaming is now handled by audiod. Time display shows
375 playback time rather than streaming time
376 - slider: update to libzmw-0.2.0
377 - para_krell: fix crash on server shutdown
378 - switch from gzip to bzip2
379
380
381 ----------------------------------------
382 0.1.7 (2005-04-18) "melting penetration"
383 ----------------------------------------
384
385 The main change in this release is clearly the oggvorbis rewrite,
386 but there are also lots of smaller changes. If you intend to use both
387 the mp3 and the ogg plugin, it is recommended to use software mixing,
388 e.g. the dmix plugin which is provided by ALSA.
389
390 - new executables: para_ovsend and para_ovrecv for sending/receiving
391 oggvorbis files via rtp. Requires the open rtp library. Get it at
392 http://www.linphone.org/ortp/
393 - rewrite of the ogg_vorbis core code
394 - configure detects libzmw and, if detected, includes
395 para_slider to the list of binaries to be built by make
396 - server stream writers read from their associated fifo rather
397 than from stdin
398 - slider: two new sliders, lastplayed and numplayed
399 - fix nasty double free bug which caused random segfaults in case of
400 mp3 files with invalid header information
401 - gui: new command line option: --stream_timeout=seconds to
402 deactivate a slot if it is idle for that many seconds (default=`5')
403 - diffstats
404
405
406 ---------------------------------------
407 0.1.6 (2005-03-05) "asymptotic balance"
408 ---------------------------------------
409
410 Only little user-visible changes in this release. Mainly bugfixes and
411 core code cleanup. This is probably the most stable version ever if you
412 stick to mp3...
413
414 - fix several memory leaks
415 - rename default name of mysql database from "music" to "paraslash".
416 Use para_server's --mysql_database option if you do not want to
417 rename your old database.
418 - rework ogg vorbis code
419 - make update command work on mysql servers with LOCAL_INFILE
420 disabled
421 - gui: improved stream I/O (slots)
422 - simplified audio format API
423 - para_pob_ogg is gone
424
425 ------------------------------------
426 0.1.5 (2004-12-31) "opaque eternity"
427 ------------------------------------
428
429 Let's slide gently into the new year.
430
431 - new: para_slider (not built automatically, type "make
432 para_slider" to build). A toy for those who always felt that
433 creating stream definitions is difficult. See screenshots,
434 README and FEATURES for more info.
435 - improved signal handling. Fixes server segfault on SIGHUP
436 for linux kernels newer than Aug 24 2004 and makes para_gui
437 race-free.
438 - reload database tool on SIGHUP
439 - improved help message for sl
440 - do not log "broken pipe" messages as errors. They are
441 perfectly ok.
442 - fix wrong error message on permission errors
443
444 -----------------------------------------
445 0.1.4 (2004-12-19) "tunneling transition"
446 -----------------------------------------
447
448 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
449 Hopefully, most of them got wiped out with this release. Some
450 enhancements went also in.
451
452 - improved error diagnostics for all commands
453 - stradd/picadd: overwrite previous contents if entry already
454 exists, rather than returning errors
455 - stradd: use current stream if invoked without args
456 - faster (and hopefully more stable) ogg-vorbis handling
457 - para_krell: reap children to avoid zombie-flooding in case
458 no server is running
459 - si: report also server pid
460 - server: don't busy-loop if dbtool reports only invalid files.
461 - gui: CTRL+C works again, fix stream_read command line option
462 - fix pic_add, hist
463 - fix mysql dbtool startup in case no database exists
464 - many small fixes and cleanups
465
466 ---------------------------------------
467 0.1.3: (2004-12-10) "vanishing inertia"
468 ---------------------------------------
469
470 Starting from this release, the database tools are integrated in the
471 server binary. This decreases server startup time, reduces code size
472 and speeds up database commands. However, the layout of the underlying
473 mysql database changed only slightly and 0.1.3 should be backwards
474 compatible in that respect.
475
476 Visible changes:
477
478 - If mysql is not detected at compile time, or fails to init
479 at runtime, fall back to the dopey database tool which should
480 always work.
481 - para_dbtool and dbtool.conf are gone. All mysql specific
482 options are read from server.conf and are prefixed by 'mysql_'.
483 - new command: cdt (change database tool)
484 - new command line option: dbtool (choose startup database tool)
485 - The name of current stream is now stored in the database,
486 so paraslash remembers its current stream when restarted.
487 - new command: csp (change stream and play)
488 - para_gui also reports current database tool and server uptime
489
490
491 -------------------------------------------
492 0.1.2: (2004-11-28) "spherical fluctuation"
493 -------------------------------------------
494
495 Point release before the big dbtool changes go in.
496
497 - dbtool: rename ca to cam (copy all meta data). It now also
498 copies numplayed and lastplayed time as well as the picture
499 id.
500 - fix endless-loop-bug caused by mp3 files with invalid header
501
502 -----------------------------------------
503 0.1.1: (2004-11-05) "floating atmosphere"
504 -----------------------------------------
505
506 - gkrellm plugin
507 - new dbtool command: mbox. Browse your sound-file collection
508 with your favorite mail reader.
509 - several small fixes
510
511 -------------------------------------
512 0.1.0: (2204-10-22) "rotating cortex"
513 -------------------------------------
514
515 - fix logging bug for loglevel > VERBOSE
516 - fix skip command
517 - correct timings for vbr mp3s
518 - modular audio format support
519 - ogg-vorbis support (experimental)
520 - new server option: autoplay
521
522 -----------------------------------------
523 0.0.99: (2004-07-25) "harmonic deviation"
524 -----------------------------------------
525
526 - rename projectname from icc to paraslash (play, archive, rate
527 and stream large audio sets happily)
528 - paraslash is no longer restricted to one particular audio
529 streaming software
530 - new dbtool commands (stradd, strq, strdel) for easy stream
531 managment w/o configuration file. That obsoletes stream_defs
532 file/config option for dbtool.
533 - picadd accepts jpeg data from stdin
534 - new server commands: ps (select previous stream), sc (song change)
535 - new default pictures for sdl_gui
536 - gui: new key_map option for binding commands and internal
537 functions to arbitrary keys, nice help screen, rip out
538 soundcard/linux specific stuff, avoid noise artefacts while jumping,
539 show silly logo on startup
540 - new executables: para_fade for fading volume, para_dbadm for
541 manipulating attributes
542 - cdb adds _all_ tables to mysql database
543 - revised and beautified documentation
544 - sample dbtool rewritten in C
545 - autoconf
