4 ----------------------------------------------
5 0.2.17 (to be announced) "isotropic threshold"
6 ----------------------------------------------
8 Only 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.
11 - be more carful wrt. signed vs. unsigned argument passing.
12 - cleanup error.h and fix some references to invalid error
15 --------------------------------------
16 0.2.16 (2007-04-05) "neural discharge"
17 --------------------------------------
19 The main change in this release is the major audio format handler
20 cleanup which removes some similar/duplicate code and makes it easier
21 to implement plugins for other audio formats. Of course, the usual mix
22 of other improvements/changes/bugfixes also made it into the release.
24 - simplified audio format handlers (most of the handling functions
25 were moved one layer up to the virtual streaming system).
26 - para_server uses mmap to read audio files
27 - repositioning of mp3 streams is much faster, in particular for
28 jumping near the end of large mp3 files.
29 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
31 - fix a bug in para_filter that caused decoding of aac files
32 to start only after a few seconds.
33 - fix osx_writer hangs
34 - simplified dccp code (thanks to Gerrit Renker)
35 - the compress filter works also on big endian systems (ppc)
37 -----------------------------------------
38 0.2.15 (2007-02-16) "inductive resonance"
39 -----------------------------------------
41 Minor improvements, more documentation and a bunch of bug fixes.
43 - para_server: The server.users file is only read once on server
44 startup rather than for each connection
45 - mp3dec: Fix decoding of corrupt mp3 files
46 - afs (audio file sender) is now called vss (virtual streaming
47 system). Consequently, the permission flags specified in
48 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
49 become VSS_READ and VSS_WRITE respectively.
50 - para_audiod/para_filter: Fix a bug that caused the last chunk
51 of audio data not being written under certain circumstances
52 - audiod: compute the difference of server time and local time
54 - para_server/para_audiod: Fix some memory leaks
55 - documentation improvements
56 - configure.ac: fix checks for para_krell
59 -------------------------------------------
60 0.2.14 (2006-10-15) "transient singularity"
61 -------------------------------------------
63 The only major enhancement of this version is the osx writer which completes
64 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
65 until now for reasons beyond the scope of this changelog entry.
67 - new output plugin for Mac Os: the osx writer
68 - rename configure command line options from --enable-xxx-headers to
69 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
70 - configure: new command line options: --with-mad-headers,
71 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
72 - some robustness fixes
73 - dymamic audio format recognition for audiod
74 - para_server: new command line option: --autoplay_delay
75 - para_audiod: new command line option: --clock_diff_count
77 ---------------------------------------
78 0.2.13 (2006-07-14) "sonic convolution"
79 ---------------------------------------
81 A bunch of new features and core changes.
83 - the new paraslash scheduler, short and sweet.
84 - Support for m4a/mp4 files via the new aac audio format
85 handler/filter (requires libfaad).
86 - each writer has its own command line parser, just like
87 para_recv and para_filter.
88 - para_client and para_audioc use the error subsystem
89 - writers are integrated in para_audiod (currently linux-only)
90 - para_client is integrated in para_audiod
91 - random/playlist selector: improved info strings
92 - new audiod commands: tasks, kill
93 - update to libortp-0.10.1
94 - para_fade: wake time defaults to 8 hours from now
95 - update to autoconf-2.60
98 ------------------------------------------
99 0.2.12 (2006-05-12) "oriented abstraction"
100 ------------------------------------------
102 Many user-visible changes in this release and lots of new
106 - the new optional dccp sender/receiver. It uses the datagram
107 congestion control protocol. You'll need a fairly new kernel
109 - paraslash works on Mac OS X (thanks to Gerd Becker)
110 - para_play renamed to para_write
111 - modular output plugin design (writers) for para_write
112 - new file_writer output plugin for para_write
113 - compress filter speed improvements
114 - update to libortp-0.9.1
115 - update to gengetopt-2.17rc
116 - para_client no longer depends on libreadline (as the
117 code for the interactive mode was removed).
118 - gcc-2-95 is no longer a supported compiler. It may still
119 work, but it gets no more testing.
120 - the tarball no longer contains the screenshot images which
121 reduces its size quite a bit.
122 - configure: new command line options: --enable-mysql-headers
123 and --enable-mysql-libs
125 ------------------------------------
126 0.2.11 (2006-03-11) "atomic duality"
127 ------------------------------------
129 Here it is, the first paraslash release developed with git. There
130 are fairly many user-visible changes in this release. As two out of
131 the three "database tools" of paraslash don't use a database at all,
132 they are now called "audio file selectors" instead.
135 - the cdt command (change database tool) becomes chs (change
137 - no more colon separators: The syntax of some options of
138 para_audiod and para_filter have changed. Use --help for
139 more info (and some examples).
140 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
141 - switch from cvs to git (should've done that earlier)
142 - the new ipc subsystem
143 - new audio file selector: playlist
144 - para_server: the dopey selector is now called "random",
145 and is the default selector. Use the --selector option to
146 choose another selector at startup, or the chs command to
147 change the selector at runtime.
148 - X86_64 fixes (thanks to Steffen Klassert)
152 --------------------------------------
153 0.2.10 (2006-02-17) "cyclic attractor"
154 --------------------------------------
156 Huge documentation update, a scrollable window for para_gui, ortp
157 improvements, and of course many small fixes not mentioned here.
158 The diffstat below is rather misleading as most insertions are due
159 to the new source documentation.
162 - para_server also uses the new error subsystem
163 - lots of new documentation (UTSL)
165 - keysyms for cursor keys and for next/previous page keys
166 - scrollable output window
167 - new internal commands: scroll up/down, page up/down
168 - fix color of command output.
169 - ortp: the --chunk_time and --header flags are no longer needed
170 for para_recv/para_audiod as this information is now encoded in
171 each rtp packet sent by para_server.
174 -------------------------------------------
175 0.2.9 (2006-01-24) "progressive turbulence"
176 -------------------------------------------
178 Internal audiod receivers/filters, the new error subsystem and
179 a lot of small improvements.
181 - para_recv and para_filter are integrated into the para_audiod
182 binary, i.e. audiod no longer spawns a new process for
183 each receiver/filter. As para_recv and para_filter might be
184 useful as standalone programs, they still get built (linked
185 against the same object files that are also used for audiod).
186 - further ortp timing improvements should reduce the CPU usage
187 of the ortp receiver.
188 - improved audio grabbing. The 'grab' command of para_audiod
189 has its own set of command line options. Read the output of
190 "para_audioc help grab" for more info.
191 - oggdec: configurable input prebuffer size.
192 - the new error subsystem gives better error diagnostics
193 and reduces code size.
196 -----------------------------------------
197 0.2.8 (2006-01-02) "dynamic accumulation"
198 -----------------------------------------
200 The new modular filter design and the para_play-hangs bugfix.
202 - new executable: para_filter. It combines para_mp3dec,
203 para_oggdec and para_compress. It also adds a further filter
204 type, wav, that just inserts a wave header at the desired point
205 of the filter chain. All 'piping' is done in-memory (i.e. no
206 read/write operations are used).
207 - para_play: fix a stupid bug that caused it to hang under
208 certain circumstances.
211 -------------------------------------------
212 0.2.7 (2006-12-27) "transparent invariance"
213 -------------------------------------------
215 Not many user-visible changes but a fair amount of internal improvements.
218 - The http sender buffers data if it can not be sent
219 out immediately (because the socket is not writable). This
220 should prevent para_server from shutting down the connection
221 too early on a loaded network.
222 - para_play also prebuffers data if it is told to start at a
223 future time by the --start_time option.
224 - The return of para_recv: It combines para_ortp_recv and
225 para_http_recv. Use the --receiver option to switch between
226 the two. para_recv builds without libortp, but contains
227 only the http receiver in this case.
228 - update to ortp 0.8.1. As this ortp release contains incompatible
229 changes, para_recv-0.2.7 won't link against older ortp libs.
230 - improved ortp timings.
231 - use of gcc-extensions that #define away for non-gcc and
235 -------------------------------------------
236 0.2.6 (2005-10-29) "recursive compensation"
237 -------------------------------------------
239 Transparent session encryption (uses openssl's Alleged RC4 cipher),
240 the internal find command and several other improvements and cleanups.
242 - Encrypt the session if encryption is requested by the client
243 (default for para_client 0.2.6). This is backwards
244 compatible, so older clients can still connect to para_server
245 0.2.6. Use the new client option --plain to request an
246 uncrypted session (off by default, must be set to on in
247 order to connect to para_server 0.2.x with 0 <= x <= 5).
248 - para_server uses an internal function to locate audio files
249 rather than calling find(1). The server option
250 --mysql_audio_file_dir replaces --mysql_find_cmd.
251 - documentation update
253 - header file cleanup
254 - para_client code cleanup
255 - para_gui: faster display of output of display commands
258 ------------------------------------------
259 0.2.5 (2005-10-13) "aggressive_resolution"
260 ------------------------------------------
262 This release adds internal senders, i.e. no more external programs are
263 spawned for sending out the audio data. There are two different senders
264 available: The http sender and the ortp sender (former para_send which
265 is no longer needed).
267 The new sender code has a plugin-like design so it can be easily
268 extended should there be be any future need for supporting another
269 network streaming protocol. All senders are completely independent of
270 each other. In particular, the http and the ortp sender can operate
273 - new server command: sender to control senders at runtime.
274 Read the output of "para_server -h" and "para_client help
275 sender" for more information.
276 - para_recv renamed to para_ortp_recv
277 - new executable: para_http_recv, a simple command line
279 - major afs/mp3/ogg code simplifications due to internal
281 - ogg timing improvements
282 - fix several minor memory leaks (found by valgrind)
283 - empty stream definitions work again
284 - com_ne(): ignore errors on remove
285 - audiod: fix segfault on server restart
288 ---------------------------------------
289 0.2.4 (2005-09-21) "toxic anticipation"
290 ---------------------------------------
292 Several small improvements, fixes and the new grab command.
295 - new command: "grab" to grab the output of the stream reader
296 or any filters. Read the output of "para_audioc help grab"
297 for more information.
300 - audioc: new command line option: --bufsize to specify a
301 buffer size different from the default size 8192.
302 - improved error diagnostics for para_play.
303 - new configure option: --enable-ssldir so search for openssl in
305 - sdl_gui: Make it look nice again for 1024x768
306 - server: report total size of memory allocated with sbrk by malloc,
307 new command line option: --announce_time
310 -----------------------------------------
311 0.2.3 (2005-09-01) "hydrophilic movement"
312 -----------------------------------------
314 Two new executables and major feature enhancements.
316 - audiod filters: It is now possible to specify arbitrary many
317 (including none) filters for each supported audio
318 format. This can be used e.g. for normalizing volume,
319 transforming or grabbing the audio stream, or for using
320 visualizers. Read the output of "para_audiod -h" for the
321 syntax of the new --filter_cmd option.
322 - new executable: para_play, a tiny alsa player. It
323 can play wave files or raw pcm (16 bit little endian)
325 - new executable: para_compress, a dynamic range compressor
326 intended to keep audio output at a consistent volume. Derived
327 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
328 - audiod: New option: --stream_delay. This can be used in
329 a local network to syncronize the audio output of all
330 clients that play the same stream.
333 ------------------------------------------
334 0.2.2 (2005-08-19) "tangential excitation"
335 ------------------------------------------
337 Mostly internal changes in this release, but also some new commands
338 for the mysql database tool.
340 - cleanup exec.c, fix para_exec bug
341 - compile time loglevel (log messages below the given level
342 won't be compiled in, which reduces the size of the
344 - new log macros that shorten the size of the source code.
345 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
346 to send only zeros. With this workaround, para_audioc works
348 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
349 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
350 (new entry), "snp" (set numplayed). Read the manual for more
354 ---------------------------------------
355 0.2.1 (2005-08-15) "surreal experience"
356 ---------------------------------------
358 Here comes paraslash-0.2.1. It contains a couple of new features and,
359 surprise, only minor bug fixes.
361 - kill noisy mp3 debug message
362 - cleanup of the build system
363 - para_server and para_client directly use the crypto routines
364 of the openssl library rather than invoking the openssl command
366 - server/audiod: new option --user to switch to the given user
367 when invoked as root. Read the output of "para_server -h" for
369 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
370 status. Default: "para_audioc stat"
371 - sdl_gui: new option --pic_cmd to be used to download the picture.
372 Default: "para_client pic"
373 - audiod: 5 slots ought to be enough for everybody
374 - audiod: new status item: Uptime, kill hup command
378 ------------------------------------------
379 0.2.0 (2005-08-06) "distributed diffusion"
380 ------------------------------------------
382 After several month of increased development activity, paraslash-0.2.0
383 has arrived. It contains many new features and is much more
384 self-contained than the old 0.1.x series. Enjoy!
387 - para_server: fix hang on song change and crash on sighup.
388 Speed up mysql queries. The DIR_LIKE macro is gone.
389 - new executables: para_audiod, the local audio daemon that
390 starts playback (uses SCM_CREDENTIALS socket magic) and
391 para_audioc, the corresponding client.
392 - new executables: para_mp3dec/para_oggdec, two really teensy
393 decoders. para_mp3dec is based on libmad, para_oggdec requires
395 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
396 they are now called para_send and para_recv respectively.
397 - documentation updates
398 - para_gui is themable. For now there is the default theme that
399 looks as before and the simple theme: blue and easy.
400 - gui: audio streaming is now handled by audiod. Time display shows
401 playback time rather than streaming time
402 - slider: update to libzmw-0.2.0
403 - para_krell: fix crash on server shutdown
404 - switch from gzip to bzip2
407 ----------------------------------------
408 0.1.7 (2005-04-18) "melting penetration"
409 ----------------------------------------
411 The main change in this release is clearly the oggvorbis rewrite,
412 but there are also lots of smaller changes. If you intend to use both
413 the mp3 and the ogg plugin, it is recommended to use software mixing,
414 e.g. the dmix plugin which is provided by ALSA.
416 - new executables: para_ovsend and para_ovrecv for sending/receiving
417 oggvorbis files via rtp. Requires the open rtp library. Get it at
418 http://www.linphone.org/ortp/
419 - rewrite of the ogg_vorbis core code
420 - configure detects libzmw and, if detected, includes
421 para_slider to the list of binaries to be built by make
422 - server stream writers read from their associated fifo rather
424 - slider: two new sliders, lastplayed and numplayed
425 - fix nasty double free bug which caused random segfaults in case of
426 mp3 files with invalid header information
427 - gui: new command line option: --stream_timeout=seconds to
428 deactivate a slot if it is idle for that many seconds (default=`5')
432 ---------------------------------------
433 0.1.6 (2005-03-05) "asymptotic balance"
434 ---------------------------------------
436 Only little user-visible changes in this release. Mainly bugfixes and
437 core code cleanup. This is probably the most stable version ever if you
440 - fix several memory leaks
441 - rename default name of mysql database from "music" to "paraslash".
442 Use para_server's --mysql_database option if you do not want to
443 rename your old database.
444 - rework ogg vorbis code
445 - make update command work on mysql servers with LOCAL_INFILE
447 - gui: improved stream I/O (slots)
448 - simplified audio format API
449 - para_pob_ogg is gone
451 ------------------------------------
452 0.1.5 (2004-12-31) "opaque eternity"
453 ------------------------------------
455 Let's slide gently into the new year.
457 - new: para_slider (not built automatically, type "make
458 para_slider" to build). A toy for those who always felt that
459 creating stream definitions is difficult. See screenshots,
460 README and FEATURES for more info.
461 - improved signal handling. Fixes server segfault on SIGHUP
462 for linux kernels newer than Aug 24 2004 and makes para_gui
464 - reload database tool on SIGHUP
465 - improved help message for sl
466 - do not log "broken pipe" messages as errors. They are
468 - fix wrong error message on permission errors
470 -----------------------------------------
471 0.1.4 (2004-12-19) "tunneling transition"
472 -----------------------------------------
474 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
475 Hopefully, most of them got wiped out with this release. Some
476 enhancements went also in.
478 - improved error diagnostics for all commands
479 - stradd/picadd: overwrite previous contents if entry already
480 exists, rather than returning errors
481 - stradd: use current stream if invoked without args
482 - faster (and hopefully more stable) ogg-vorbis handling
483 - para_krell: reap children to avoid zombie-flooding in case
485 - si: report also server pid
486 - server: don't busy-loop if dbtool reports only invalid files.
487 - gui: CTRL+C works again, fix stream_read command line option
489 - fix mysql dbtool startup in case no database exists
490 - many small fixes and cleanups
492 ---------------------------------------
493 0.1.3: (2004-12-10) "vanishing inertia"
494 ---------------------------------------
496 Starting from this release, the database tools are integrated in the
497 server binary. This decreases server startup time, reduces code size
498 and speeds up database commands. However, the layout of the underlying
499 mysql database changed only slightly and 0.1.3 should be backwards
500 compatible in that respect.
504 - If mysql is not detected at compile time, or fails to init
505 at runtime, fall back to the dopey database tool which should
507 - para_dbtool and dbtool.conf are gone. All mysql specific
508 options are read from server.conf and are prefixed by 'mysql_'.
509 - new command: cdt (change database tool)
510 - new command line option: dbtool (choose startup database tool)
511 - The name of current stream is now stored in the database,
512 so paraslash remembers its current stream when restarted.
513 - new command: csp (change stream and play)
514 - para_gui also reports current database tool and server uptime
517 -------------------------------------------
518 0.1.2: (2004-11-28) "spherical fluctuation"
519 -------------------------------------------
521 Point release before the big dbtool changes go in.
523 - dbtool: rename ca to cam (copy all meta data). It now also
524 copies numplayed and lastplayed time as well as the picture
526 - fix endless-loop-bug caused by mp3 files with invalid header
528 -----------------------------------------
529 0.1.1: (2004-11-05) "floating atmosphere"
530 -----------------------------------------
533 - new dbtool command: mbox. Browse your sound-file collection
534 with your favorite mail reader.
535 - several small fixes
537 -------------------------------------
538 0.1.0: (2204-10-22) "rotating cortex"
539 -------------------------------------
541 - fix logging bug for loglevel > VERBOSE
543 - correct timings for vbr mp3s
544 - modular audio format support
545 - ogg-vorbis support (experimental)
546 - new server option: autoplay
548 -----------------------------------------
549 0.0.99: (2004-07-25) "harmonic deviation"
550 -----------------------------------------
552 - rename projectname from icc to paraslash (play, archive, rate
553 and stream large audio sets happily)
554 - paraslash is no longer restricted to one particular audio
556 - new dbtool commands (stradd, strq, strdel) for easy stream
557 managment w/o configuration file. That obsoletes stream_defs
558 file/config option for dbtool.
559 - picadd accepts jpeg data from stdin
560 - new server commands: ps (select previous stream), sc (song change)
561 - new default pictures for sdl_gui
562 - gui: new key_map option for binding commands and internal
563 functions to arbitrary keys, nice help screen, rip out
564 soundcard/linux specific stuff, avoid noise artefacts while jumping,
565 show silly logo on startup
566 - new executables: para_fade for fading volume, para_dbadm for
567 manipulating attributes
568 - cdb adds _all_ tables to mysql database
569 - revised and beautified documentation
570 - sample dbtool rewritten in C
573 ---------------------------------------------
574 0.0.98: (2003-12-26) "incremental smoothness"
575 ---------------------------------------------
577 - kick icecast in favour of poc. That removes some races and reduces
578 core code considerably.
579 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
580 give finer info on afs' status.
581 - gui can start decoder (see config options). Further new gui
582 commands: refresh (^L), jmp (F1-F10)
583 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
584 terminates gui. This fixes dead instances consuming memory
586 - new dbtool command: verb for sending verbatim sql queries.
587 - fix pid_list races (by removing pid_list)
594 - installation prefix now defaults to /usr/local
595 - new commands for gui: snozze, sleep and reread config
596 - config file for gui and sdl_gui
597 - fix problems with filenames containing funny characters
598 (reported by Thomas Forell)
599 - improved signal handling for gui, now it rereads conf on SIGHUP
600 - new dbtool command: cdb (create database)
601 - switch from argtable to gengetopt
602 - major code cleanup and speed improvements
603 - fix several potential buffer overflows
604 - many small fixes and cleanups
610 - easy stream_defs syntax
611 - sdl_gui can display images associated to the file being played
612 - Major feature enhancements for icc_gui including dynamic text
613 placement and the top/bottom window design
614 - vrfy/clean now also checks for NULL values in attributes as
615 well as for invalid picture pointers
616 - fix long outstanding case sensitivity bug
617 - many small fixes and cleanups
623 - sdl gui runs much faster
624 - new dbtool command: ca (copy attributes)
625 - count and display number of times the song has been played
626 - new feature: scoring
