3
4 ----------------------------------------------
5 0.2.17 (to be announced) "isotropic threshold"
6 ----------------------------------------------
7
8 Mainly bugfixes and cleanups in this version which marks the end of
9 the 0.2.x series if no serious bugs show up after the release.
10
11 - mysql_selector: fix a locking bug.
12 - universal chunk queueing.
13 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
14 to Gerrit Renker).
15 - be more carful wrt. signed vs. unsigned argument passing.
16 - cleanup error.h and fix some references to invalid error
17 codes.
18 - update to gengetopt-2.21.
19 - update to ortp-0.13.1.
20 - autoconf: extend checks for headers, library functions and
21 compiler characteristics.
22
23 --------------------------------------
24 0.2.16 (2007-04-05) "neural discharge"
25 --------------------------------------
26
27 The main change in this release is the major audio format handler
28 cleanup which removes some similar/duplicate code and makes it easier
29 to implement plugins for other audio formats. Of course, the usual mix
30 of other improvements/changes/bugfixes also made it into the release.
31
32 - simplified audio format handlers (most of the handling functions
33 were moved one layer up to the virtual streaming system).
34 - para_server uses mmap to read audio files
35 - repositioning of mp3 streams is much faster, in particular for
36 jumping near the end of large mp3 files.
37 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
38 and AFS_WRITE.
39 - fix a bug in para_filter that caused decoding of aac files
40 to start only after a few seconds.
41 - fix osx_writer hangs
42 - simplified dccp code (thanks to Gerrit Renker)
43 - the compress filter works also on big endian systems (ppc)
44
45 -----------------------------------------
46 0.2.15 (2007-02-16) "inductive resonance"
47 -----------------------------------------
48
49 Minor improvements, more documentation and a bunch of bug fixes.
50
51 - para_server: The server.users file is only read once on server
52 startup rather than for each connection
53 - mp3dec: Fix decoding of corrupt mp3 files
54 - afs (audio file sender) is now called vss (virtual streaming
55 system). Consequently, the permission flags specified in
56 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
57 become VSS_READ and VSS_WRITE respectively.
58 - para_audiod/para_filter: Fix a bug that caused the last chunk
59 of audio data not being written under certain circumstances
60 - audiod: compute the difference of server time and local time
61 correctly
62 - para_server/para_audiod: Fix some memory leaks
63 - documentation improvements
64 - configure.ac: fix checks for para_krell
65 - new man pages
66
67 -------------------------------------------
68 0.2.14 (2006-10-15) "transient singularity"
69 -------------------------------------------
70
71 The only major enhancement of this version is the osx writer which completes
72 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
73 until now for reasons beyond the scope of this changelog entry.
74
75 - new output plugin for Mac Os: the osx writer
76 - rename configure command line options from --enable-xxx-headers to
77 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
78 - configure: new command line options: --with-mad-headers,
79 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
80 - some robustness fixes
81 - dymamic audio format recognition for audiod
82 - para_server: new command line option: --autoplay_delay
83 - para_audiod: new command line option: --clock_diff_count
84
85 ---------------------------------------
86 0.2.13 (2006-07-14) "sonic convolution"
87 ---------------------------------------
88
89 A bunch of new features and core changes.
90
91 - the new paraslash scheduler, short and sweet.
92 - Support for m4a/mp4 files via the new aac audio format
93 handler/filter (requires libfaad).
94 - each writer has its own command line parser, just like
95 para_recv and para_filter.
96 - para_client and para_audioc use the error subsystem
97 - writers are integrated in para_audiod (currently linux-only)
98 - para_client is integrated in para_audiod
99 - random/playlist selector: improved info strings
100 - new audiod commands: tasks, kill
101 - update to libortp-0.10.1
102 - para_fade: wake time defaults to 8 hours from now
103 - update to autoconf-2.60
104
105
106 ------------------------------------------
107 0.2.12 (2006-05-12) "oriented abstraction"
108 ------------------------------------------
109
110 Many user-visible changes in this release and lots of new
111 features:
112
113
114 - the new optional dccp sender/receiver. It uses the datagram
115 congestion control protocol. You'll need a fairly new kernel
116 for this.
117 - paraslash works on Mac OS X (thanks to Gerd Becker)
118 - para_play renamed to para_write
119 - modular output plugin design (writers) for para_write
120 - new file_writer output plugin for para_write
121 - compress filter speed improvements
122 - update to libortp-0.9.1
123 - update to gengetopt-2.17rc
124 - para_client no longer depends on libreadline (as the
125 code for the interactive mode was removed).
126 - gcc-2-95 is no longer a supported compiler. It may still
127 work, but it gets no more testing.
128 - the tarball no longer contains the screenshot images which
129 reduces its size quite a bit.
130 - configure: new command line options: --enable-mysql-headers
131 and --enable-mysql-libs
132
133 ------------------------------------
134 0.2.11 (2006-03-11) "atomic duality"
135 ------------------------------------
136
137 Here it is, the first paraslash release developed with git. There
138 are fairly many user-visible changes in this release. As two out of
139 the three "database tools" of paraslash don't use a database at all,
140 they are now called "audio file selectors" instead.
141
142
143 - the cdt command (change database tool) becomes chs (change
144 selector)
145 - no more colon separators: The syntax of some options of
146 para_audiod and para_filter have changed. Use --help for
147 more info (and some examples).
148 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
149 - switch from cvs to git (should've done that earlier)
150 - the new ipc subsystem
151 - new audio file selector: playlist
152 - para_server: the dopey selector is now called "random",
153 and is the default selector. Use the --selector option to
154 choose another selector at startup, or the chs command to
155 change the selector at runtime.
156 - X86_64 fixes (thanks to Steffen Klassert)
157 - para_play fixes
158
159
160 --------------------------------------
161 0.2.10 (2006-02-17) "cyclic attractor"
162 --------------------------------------
163
164 Huge documentation update, a scrollable window for para_gui, ortp
165 improvements, and of course many small fixes not mentioned here.
166 The diffstat below is rather misleading as most insertions are due
167 to the new source documentation.
168
169 - autoconf cleanup
170 - para_server also uses the new error subsystem
171 - lots of new documentation (UTSL)
172 - gui improvements:
173 - keysyms for cursor keys and for next/previous page keys
174 - scrollable output window
175 - new internal commands: scroll up/down, page up/down
176 - fix color of command output.
177 - ortp: the --chunk_time and --header flags are no longer needed
178 for para_recv/para_audiod as this information is now encoded in
179 each rtp packet sent by para_server.
180
181
182 -------------------------------------------
183 0.2.9 (2006-01-24) "progressive turbulence"
184 -------------------------------------------
185
186 Internal audiod receivers/filters, the new error subsystem and
187 a lot of small improvements.
188
189 - para_recv and para_filter are integrated into the para_audiod
190 binary, i.e. audiod no longer spawns a new process for
191 each receiver/filter. As para_recv and para_filter might be
192 useful as standalone programs, they still get built (linked
193 against the same object files that are also used for audiod).
194 - further ortp timing improvements should reduce the CPU usage
195 of the ortp receiver.
196 - improved audio grabbing. The 'grab' command of para_audiod
197 has its own set of command line options. Read the output of
198 "para_audioc help grab" for more info.
199 - oggdec: configurable input prebuffer size.
200 - the new error subsystem gives better error diagnostics
201 and reduces code size.
202
203
204 -----------------------------------------
205 0.2.8 (2006-01-02) "dynamic accumulation"
206 -----------------------------------------
207
208 The new modular filter design and the para_play-hangs bugfix.
209
210 - new executable: para_filter. It combines para_mp3dec,
211 para_oggdec and para_compress. It also adds a further filter
212 type, wav, that just inserts a wave header at the desired point
213 of the filter chain. All 'piping' is done in-memory (i.e. no
214 read/write operations are used).
215 - para_play: fix a stupid bug that caused it to hang under
216 certain circumstances.
217
218
219 -------------------------------------------
220 0.2.7 (2006-12-27) "transparent invariance"
221 -------------------------------------------
222
223 Not many user-visible changes but a fair amount of internal improvements.
224
225
226 - The http sender buffers data if it can not be sent
227 out immediately (because the socket is not writable). This
228 should prevent para_server from shutting down the connection
229 too early on a loaded network.
230 - para_play also prebuffers data if it is told to start at a
231 future time by the --start_time option.
232 - The return of para_recv: It combines para_ortp_recv and
233 para_http_recv. Use the --receiver option to switch between
234 the two. para_recv builds without libortp, but contains
235 only the http receiver in this case.
236 - update to ortp 0.8.1. As this ortp release contains incompatible
237 changes, para_recv-0.2.7 won't link against older ortp libs.
238 - improved ortp timings.
239 - use of gcc-extensions that #define away for non-gcc and
240 gcc < 3.0.
241
242
243 -------------------------------------------
244 0.2.6 (2005-10-29) "recursive compensation"
245 -------------------------------------------
246
247 Transparent session encryption (uses openssl's Alleged RC4 cipher),
248 the internal find command and several other improvements and cleanups.
249
250 - Encrypt the session if encryption is requested by the client
251 (default for para_client 0.2.6). This is backwards
252 compatible, so older clients can still connect to para_server
253 0.2.6. Use the new client option --plain to request an
254 uncrypted session (off by default, must be set to on in
255 order to connect to para_server 0.2.x with 0 <= x <= 5).
256 - para_server uses an internal function to locate audio files
257 rather than calling find(1). The server option
258 --mysql_audio_file_dir replaces --mysql_find_cmd.
259 - documentation update
260 - man pages
261 - header file cleanup
262 - para_client code cleanup
263 - para_gui: faster display of output of display commands
264
265
266 ------------------------------------------
267 0.2.5 (2005-10-13) "aggressive resolution"
268 ------------------------------------------
269
270 This release adds internal senders, i.e. no more external programs are
271 spawned for sending out the audio data. There are two different senders
272 available: The http sender and the ortp sender (former para_send which
273 is no longer needed).
274
275 The new sender code has a plugin-like design so it can be easily
276 extended should there be be any future need for supporting another
277 network streaming protocol. All senders are completely independent of
278 each other. In particular, the http and the ortp sender can operate
279 in parallel.
280
281 - new server command: sender to control senders at runtime.
282 Read the output of "para_server -h" and "para_client help
283 sender" for more information.
284 - para_recv renamed to para_ortp_recv
285 - new executable: para_http_recv, a simple command line
286 http receiver.
287 - major afs/mp3/ogg code simplifications due to internal
288 senders.
289 - ogg timing improvements
290 - fix several minor memory leaks (found by valgrind)
291 - empty stream definitions work again
292 - com_ne(): ignore errors on remove
293 - audiod: fix segfault on server restart
294
295
296 ---------------------------------------
297 0.2.4 (2005-09-21) "toxic anticipation"
298 ---------------------------------------
299
300 Several small improvements, fixes and the new grab command.
301
302 - audiod:
303 - new command: "grab" to grab the output of the stream reader
304 or any filters. Read the output of "para_audioc help grab"
305 for more information.
306 - fix memory leak
307 - code cleanup
308 - audioc: new command line option: --bufsize to specify a
309 buffer size different from the default size 8192.
310 - improved error diagnostics for para_play.
311 - new configure option: --enable-ssldir so search for openssl in
312 non-standard places
313 - sdl_gui: Make it look nice again for 1024x768
314 - server: report total size of memory allocated with sbrk by malloc,
315 new command line option: --announce_time
316
317
318 -----------------------------------------
319 0.2.3 (2005-09-01) "hydrophilic movement"
320 -----------------------------------------
321
322 Two new executables and major feature enhancements.
323
324 - audiod filters: It is now possible to specify arbitrary many
325 (including none) filters for each supported audio
326 format. This can be used e.g. for normalizing volume,
327 transforming or grabbing the audio stream, or for using
328 visualizers. Read the output of "para_audiod -h" for the
329 syntax of the new --filter_cmd option.
330 - new executable: para_play, a tiny alsa player. It
331 can play wave files or raw pcm (16 bit little endian)
332 from stdin.
333 - new executable: para_compress, a dynamic range compressor
334 intended to keep audio output at a consistent volume. Derived
335 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
336 - audiod: New option: --stream_delay. This can be used in
337 a local network to syncronize the audio output of all
338 clients that play the same stream.
339
340
341 ------------------------------------------
342 0.2.2 (2005-08-19) "tangential excitation"
343 ------------------------------------------
344
345 Mostly internal changes in this release, but also some new commands
346 for the mysql database tool.
347
348 - cleanup exec.c, fix para_exec bug
349 - compile time loglevel (log messages below the given level
350 won't be compiled in, which reduces the size of the
351 resulting binaries)
352 - new log macros that shorten the size of the source code.
353 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
354 to send only zeros. With this workaround, para_audioc works
355 again.
356 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
357 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
358 (new entry), "snp" (set numplayed). Read the manual for more
359 information.
360
361
362 ---------------------------------------
363 0.2.1 (2005-08-15) "surreal experience"
364 ---------------------------------------
365
366 Here comes paraslash-0.2.1. It contains a couple of new features and,
367 surprise, only minor bug fixes.
368
369 - kill noisy mp3 debug message
370 - cleanup of the build system
371 - para_server and para_client directly use the crypto routines
372 of the openssl library rather than invoking the openssl command
373 line utitlity
374 - server/audiod: new option --user to switch to the given user
375 when invoked as root. Read the output of "para_server -h" for
376 more information.
377 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
378 status. Default: "para_audioc stat"
379 - sdl_gui: new option --pic_cmd to be used to download the picture.
380 Default: "para_client pic"
381 - audiod: 5 slots ought to be enough for everybody
382 - audiod: new status item: Uptime, kill hup command
383
384
385
386 ------------------------------------------
387 0.2.0 (2005-08-06) "distributed diffusion"
388 ------------------------------------------
389
390 After several month of increased development activity, paraslash-0.2.0
391 has arrived. It contains many new features and is much more
392 self-contained than the old 0.1.x series. Enjoy!
393
394
395 - para_server: fix hang on song change and crash on sighup.
396 Speed up mysql queries. The DIR_LIKE macro is gone.
397 - new executables: para_audiod, the local audio daemon that
398 starts playback (uses SCM_CREDENTIALS socket magic) and
399 para_audioc, the corresponding client.
400 - new executables: para_mp3dec/para_oggdec, two really teensy
401 decoders. para_mp3dec is based on libmad, para_oggdec requires
402 libvorbisfile.
403 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
404 they are now called para_send and para_recv respectively.
405 - documentation updates
406 - para_gui is themable. For now there is the default theme that
407 looks as before and the simple theme: blue and easy.
408 - gui: audio streaming is now handled by audiod. Time display shows
409 playback time rather than streaming time
410 - slider: update to libzmw-0.2.0
411 - para_krell: fix crash on server shutdown
412 - switch from gzip to bzip2
413
414
415 ----------------------------------------
416 0.1.7 (2005-04-18) "melting penetration"
417 ----------------------------------------
418
419 The main change in this release is clearly the oggvorbis rewrite,
420 but there are also lots of smaller changes. If you intend to use both
421 the mp3 and the ogg plugin, it is recommended to use software mixing,
422 e.g. the dmix plugin which is provided by ALSA.
423
424 - new executables: para_ovsend and para_ovrecv for sending/receiving
425 oggvorbis files via rtp. Requires the open rtp library. Get it at
426 http://www.linphone.org/ortp/
427 - rewrite of the ogg_vorbis core code
428 - configure detects libzmw and, if detected, includes
429 para_slider to the list of binaries to be built by make
430 - server stream writers read from their associated fifo rather
431 than from stdin
432 - slider: two new sliders, lastplayed and numplayed
433 - fix nasty double free bug which caused random segfaults in case of
434 mp3 files with invalid header information
435 - gui: new command line option: --stream_timeout=seconds to
436 deactivate a slot if it is idle for that many seconds (default=`5')
437 - diffstats
438
439
440 ---------------------------------------
441 0.1.6 (2005-03-05) "asymptotic balance"
442 ---------------------------------------
443
444 Only little user-visible changes in this release. Mainly bugfixes and
445 core code cleanup. This is probably the most stable version ever if you
446 stick to mp3...
447
448 - fix several memory leaks
449 - rename default name of mysql database from "music" to "paraslash".
450 Use para_server's --mysql_database option if you do not want to
451 rename your old database.
452 - rework ogg vorbis code
453 - make update command work on mysql servers with LOCAL_INFILE
454 disabled
455 - gui: improved stream I/O (slots)
456 - simplified audio format API
457 - para_pob_ogg is gone
458
459 ------------------------------------
460 0.1.5 (2004-12-31) "opaque eternity"
461 ------------------------------------
462
463 Let's slide gently into the new year.
464
465 - new: para_slider (not built automatically, type "make
466 para_slider" to build). A toy for those who always felt that
467 creating stream definitions is difficult. See screenshots,
468 README and FEATURES for more info.
469 - improved signal handling. Fixes server segfault on SIGHUP
470 for linux kernels newer than Aug 24 2004 and makes para_gui
471 race-free.
472 - reload database tool on SIGHUP
473 - improved help message for sl
474 - do not log "broken pipe" messages as errors. They are
475 perfectly ok.
476 - fix wrong error message on permission errors
477
478 -----------------------------------------
479 0.1.4 (2004-12-19) "tunneling transition"
480 -----------------------------------------
481
482 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
483 Hopefully, most of them got wiped out with this release. Some
484 enhancements went also in.
485
486 - improved error diagnostics for all commands
487 - stradd/picadd: overwrite previous contents if entry already
488 exists, rather than returning errors
489 - stradd: use current stream if invoked without args
490 - faster (and hopefully more stable) ogg-vorbis handling
491 - para_krell: reap children to avoid zombie-flooding in case
492 no server is running
493 - si: report also server pid
494 - server: don't busy-loop if dbtool reports only invalid files.
495 - gui: CTRL+C works again, fix stream_read command line option
496 - fix pic_add, hist
497 - fix mysql dbtool startup in case no database exists
498 - many small fixes and cleanups
499
500 ---------------------------------------
501 0.1.3: (2004-12-10) "vanishing inertia"
502 ---------------------------------------
503
504 Starting from this release, the database tools are integrated in the
505 server binary. This decreases server startup time, reduces code size
506 and speeds up database commands. However, the layout of the underlying
507 mysql database changed only slightly and 0.1.3 should be backwards
508 compatible in that respect.
509
510 Visible changes:
511
512 - If mysql is not detected at compile time, or fails to init
513 at runtime, fall back to the dopey database tool which should
514 always work.
515 - para_dbtool and dbtool.conf are gone. All mysql specific
516 options are read from server.conf and are prefixed by 'mysql_'.
517 - new command: cdt (change database tool)
518 - new command line option: dbtool (choose startup database tool)
519 - The name of current stream is now stored in the database,
520 so paraslash remembers its current stream when restarted.
521 - new command: csp (change stream and play)
522 - para_gui also reports current database tool and server uptime
523
524
525 -------------------------------------------
526 0.1.2: (2004-11-28) "spherical fluctuation"
527 -------------------------------------------
528
529 Point release before the big dbtool changes go in.
530
531 - dbtool: rename ca to cam (copy all meta data). It now also
532 copies numplayed and lastplayed time as well as the picture
533 id.
534 - fix endless-loop-bug caused by mp3 files with invalid header
535
536 -----------------------------------------
537 0.1.1: (2004-11-05) "floating atmosphere"
538 -----------------------------------------
539
540 - gkrellm plugin
541 - new dbtool command: mbox. Browse your sound-file collection
542 with your favorite mail reader.
543 - several small fixes
