[paraslash.git] / NEWS
1 -------------------------------------------
2 0.4.8 (to be announced) "nested assignment"
3 -------------------------------------------
4
5 --------------------------------------
6 0.4.7 (2011-06-01) "infinite rollback"
7 --------------------------------------
8
9 The new ao writer, support for ssh RSA keys and a couple of other
10 enhancements.
11
12 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
13 platforms through the libao audio library.
14 - Support for RSA keys generated with ssh-keygen.
15 - configure: improved options for ogg/vorbis/speex.
16 - The git version reported by --version always matches HEAD.
17 - The autogen script detects the number of processors and
18 runs a parallel make if possible.
19 - Major cleanup of the crypto API.
20 - Documentation updates.
21
22 ------------------------------------------
23 0.4.6 (2011-03-31) "deterministic entropy"
24 ------------------------------------------
25
26 Lots of ogg/vorbis improvements, the new test suite, enhancements
27 for para_gui and a fair amount of other bug fixes.
28
29 - For DCCP/OGG streams the audio file header is only sent once
30 at the beginning of the stream rather than periodically
31 every five seconds. This reduces network traffic and the
32 FEC group size.
33 - The vorbis comment header is replaced by an empty dummy header
34 before the header is sent over the network. This also results in
35 less network traffic and smaller FEC groups.
36 - The new "test" make target allows to perform some sanity checks prior
37 to installing the package.
38 - ogg timing fixes and performance improvements
39 - Scheduler improvements
40 - Proper exit codes for para_write
41 - para_gui: New option --theme to select a startup theme. Several
42 other improvements and fixes.
43 - aacdec error message cleanups
44 - simplified color error handling
45
46 --------------------------------------------
47 0.4.5 (2010-12-17) "symmetric randomization"
48 --------------------------------------------
49
50 Bug fixes, internal cleanups and variable-sized FEC slices.
51
52 - Contains a fix for an invalid-free-bug in the ogg audio format
53 handler code.
54 - Switching off the DCCP sender works again.
55 - para_audiod handles crashes of para_server more robustly.
56 - Internal scheduler and writer cleanups.
57 - Reduced latency due to variable-sized FEC slices.
58 - Improved documentation and error diagnostics.
59 - The build of para_server is now optional, allowing the build
60 to succeed in case libosl is not installed.
61
62 ------------------------------------------
63 0.4.4 (2010-08-06) "persistent regularity"
64 ------------------------------------------
65
66 Support for yet another audio format, para_write improvements and
67 bug fixes.
68
69 - Support for the speex codec.
70 - Support for sample formats other than 16 bit little endian.
71 - error2.h is now created by a perl script which speeds up configure
72 considerably.
73 - Fix a bug in the aac decoder which could lead to segfaults in
74 para_filter/para_audiod.
75 - Fixes for autoconf-2.66.
76
77 ----------------------------------------
78 0.4.3 (2010-07-05) "imaginary radiation"
79 ----------------------------------------
80
81 Many improvements for the DCCP and the UDP transport, the new user
82 manual and the usual mix of bug fixes and internal improvements.
83
84 - FEC support for the DCCP sender (Gerrit Renker). The new
85 --dccp_max_slice_size, --dccp_data_slices_per_group and
86 --dccp_slices_per_group options can be used to set the FEC
87 parameters for the DCCP transport.
88 - DNS lookups for UDP targets (Gerrit Renker).
89 - The new user manual replaces the README, README.afs, REQUIREMENTS
90 and INSTALL documents.
91 - Fix an end-of-file detection bug in the oggdec filter.
92 - The new nonblock API.
93 - Both options of the oggdec filter have been removed.
94 - New debug mode for the internal scheduler.
95
96 ------------------------------------------
97 0.4.2 (2010-04-23) "associative expansion"
98 ------------------------------------------
99
100 It's been some time since the last release, but finally here is
101 paraslash-0.4.2. The bulk of the changes comes from the new buffer
102 tree API, but there are changes all over the tree. Mainly performance
103 and usability improvements, but also quite some bug fixes.
104
105 - The new buffer tree API.
106 - DCCP: Support for CCID negotiation (Gerrit Renker).
107 - UDP robustness fixes.
108 - The --bufsize option for mp3dec is gone as it no longer makes sense
109 for the new buffer tree API.
110 - Fix audible buffer underruns for wma streams.
111 - The alsa writer no longer prints meaningless underrun durations.
112 - audiod: Defaults work also for udp streams. If no filter is
113 given for an audio format that is received via upd, fecdec is
114 automatically added as the first filter (along with the decoder).
115
116 ---------------------------------------
117 0.4.1 (2009-12-22) "concurrent horizon"
118 ---------------------------------------
119
120 Support for another audio format, minor feature enhancements and lots of bug
121 fixes. All fixes that have been accumulated in the maint branch (in particular
122 those mentionened in the 0.3.6 release notes) appear in this release as well.
123
124 - wma support.
125 - new afh option: --human to activate human-readable output.
126 - new server/audiod option: --log-timing to print timing information.
127 - build system improvements.
128 - source code documentation updates.
129
130 -------------------------------------
131 0.3.6 (2009-12-07) "cubic continuity"
132 -------------------------------------
133
134 Quite a few bugs have been found and fixed since 0.3.5, so here's
135 another 0.3.x release. No new features.
136
137 - Always check return value of malloc().
138 - ogg vorbis/FEC: Do not write garbage after the audio file header.
139 - exit if root privileges could not be dropped.
140 - FEC: Fix computation of extra slices.
141 - oss: Fix check for empty input buffer.
142 - Avoid buffer underruns due to filter chain output buffer constraints.
143 - server: Fix assignment of afs_pid.
144 - Don't panic if the afs database contains unknown audio formats.
145 - http/dccp: Do not send the audio file header twice.
146 - FEC: Timing improvements.
147
148 ----------------------------------------------
149 0.4.0 (2009-11-10) "simultaneous independence"
150 ----------------------------------------------
151
152 Two significant changes which require the new version number: The
153 improved authentication dialog and the fact that the database code
154 has been moved to a library, libosl. To use the new version, you have
155 to generate new RSA keys, see INSTALL for details. A shell script is
156 provided for conversion of the 0.3 database to the new 0.4 format.
157
158 - stronger crypto for client authentication
159 - the database code has been moved to a library
160 - improved status item handling
161 - cleanup of the build system
162 - The "-V" option now also prints the git version
163 - the new parser-friendly listing mode for the ls and stat commands
164 - mandatory rc4 encryption
165 - major audio format handler cleanups
166 - (id3,...) tags are no longer stored as a combined string in the database
167 - new mood methods: artist_matches, title_matches, comment_matches,
168 album_matches, year_maches, year.
169
170 --------------------------------------------
171 0.3.5 (2009-09-21) "symplectic separability"
172 --------------------------------------------
173
174 Full client support for *BSD Unixes, complete re-write of the ogg
175 vorbis audio format handler, various improvements all over the place
176 and the usual mix of bugfixes. This release marks the end of the 0.3
177 series if no serious problems show up.
178
179 - the new oss writer (supported on *BSD and Linux)
180 - rewrite of the ogg vorbis audio format handler. It's
181 recommended to replace the chunk tables of existing ogg
182 vorbis files in the afs database by re-adding these files
183 with "add -f".
184 - support for netmask subsets (Gerrit Renker)
185 - the new prebuffer filter
186 - improved signal handling
187 - variable fec output buffer size
188 - improved FEC timing fixes audible buffer underruns in UDP mode
189 - --log_color actually works
190 - new ls option: -d (print dates as seconds after the epoch)
191 - update to gengetopt 2.22.2
192 - support for RSA keys of size > 512 bits
193 - new option "mixer_channel" for para_fade
194
195 -----------------------------------------
196 0.3.4 (2009-05-07) "elliptic inheritance"
197 -----------------------------------------
198
199 The new udp sender, forward error correction, colored logs and various
200 other improvements. As the udp sender does not depend on any special
201 libraries, it is built unconditionally.
202
203 - The udp sender replaces the ortp sender. The new code uses forward
204 error correction to protect against packet losses. Many thanks to
205 Gerrit Renker for providing ipv6 support.
206 - The default port for udp streaming now defaults to 8000, like
207 for the http and the dccp senders/receivers.
208 - Loglevels are now specified as symbolic names, e.g.
209 "--loglevel info".
210 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
211 - para_server/para_audiod: Color support for log messages.
212 - new options for mp3dec: --ignore-crc, --bufsize
213 - new audiod option: --config-file.
214 - gengetopt cleanups.
215 - Improved help/man pages: The documentation of para_audiod,
216 para_recv, para_filter and para_write now also contains
217 all options of the available receivers/filters/writers. The
218 man page of para_fade contains a description of the different
219 modes of operation.
220 - More source code documentation.
221 - vss timing fixes.
222
223 --------------------------------------------
224 0.3.3 (2008-12-01) "axiomatic perspectivity"
225 --------------------------------------------
226
227 Internal code cleanups, bug fixes, improved tag handling and the new
228 amplification filter.
229
230 - para_server uses the generic scheduling code.
231 - overhaul of the virtual streaming system.
232 - mp3: id3 version 2 support via libid3tag (optional)
233 - ogg: vorbis comment support.
234 - aac meta info support.
235 - mp3 audio format handler cleanups.
236 - new filter: "amp" to amplify the amplitude of the audio stream
237 - new status item/database entry: amplification. It is
238 used by the amp filter to pre-amplify the audio stream.
239 - fix a close-without-open bug in para_write.
240 - fix a bug in com_init() which was introduced in 0.3.2.
241 - better error diagnostics for para_client.
242
243 -----------------------------------------
244 0.3.2 (2008-04-11) "probabilistic parity"
245 -----------------------------------------
246
247 The new para_afh executable, scheduling and documentation improvements.
248
249 - new ls option: -lc (list chunk table)
250 - new executable: para_afh, the stand-alone audio file handler tool
251 - afs commands can send output more than SHMMAX (32MB on Linux). This
252 also reduces the memory usage of commands that produce large amounts
253 of output.
254 - major scheduler and audiod cleanups.
255 - more detailed and much nicer man pages.
256
257 ---------------------------------------
258 0.3.1 (2008-02-23) "liquid interaction"
259 ---------------------------------------
260
261 A mix of cleanups, bug fixes, improvements, and some new features. No
262 significant changes to the new database (osl) code, which is generally
263 a good sign.
264
265 - Share some similar/duplicate code between the http and the
266 dccp sender.
267 - Generic access control lists for paraslash senders.
268 - dccp sender: Access control lists, connection limiting and support
269 for the allow,deny,on,off,help sender commands.
270 - The default dccp port changed from 5001 to 8000 (suggested by
271 Gerrit Renker).
272 - para_server starts even if not all public keys could be loaded.
273 - Audiod performance improvements.
274 - fix a bug in the "off" command of the http sender.
275 - fix some fd and memory leaks.
276 - Update to gengetopt-2.22.
277
278 -------------------------------------
279 0.3.0 (2008-01-12) "solar saturation"
280 -------------------------------------
281
282 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
283
284
285 Usually one might expect lots of new features AND a big increase in size
286 for a major release like this.
287
288 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
289 ever. The decrease in size is mostly due to the removal of some
290 graphical tools (which were only quick hacks anyway). But also the
291 fact that the mysql code is gone cuts down the size a bit.
292
293 Being independent of mysql comes at a cost: The fact that paraslash
294 now contains its own database (the object storage layer, osl) increases
295 the (stripped) binary size of para_server by ~50K on i386.
296
297 - no more restrictions on unique basenames.
298 - independent of mysql: The new self-contained object
299 storage layer (osl) replaces the mysql database.
300 - New executable para_fsck: Check integrity of osl tables.
301 - Lyrics support.
302 - Reliable audio file move/rename detection.
303 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
304 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
305 Solaris (sparc64).
306 - the new osl-based audio file selector (afs) replaces the random,
307 the playlist and the mysql selector of paraslash-0.2.x.
308 - IPv6 support (thanks to Gerrit Renker).
309 - paraslash-0.2.x streams are now called "moods". Writing
310 0.3.x-mood definitions should be both easier and more
311 powerful than writing 0.2.x-stream definitions.
312 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
313 been removed. The world is a better place without them. However,
314 para_gui is still there.
315 - afs tracks audio file selection also in playlist mode.
316 - few easy-to-use afs commands replace the many not-so-easy-to-use
317 mysql commands (and are available also in playlist mode).
318 - Improved error subsystem.
319 - The earth-shaking new logo.
320
321 -----------------------------------------
322 0.2.17 (2007-11-20) "isotropic threshold"
323 -----------------------------------------
324
325 Mainly bugfixes and cleanups in this version which marks the end of
326 the 0.2.x series if no serious bugs show up after the release.
327
328 - mysql_selector: fix a locking bug.
329 - universal chunk queueing.
330 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
331 to Gerrit Renker).
332 - be more carful wrt. signed vs. unsigned argument passing.
333 - cleanup error.h and fix some references to invalid error
334 codes.
335 - update to gengetopt-2.21.
336 - update to ortp-0.13.1.
337 - autoconf: extend checks for headers, library functions and
338 compiler characteristics.
339 - Fix streaming of large mp3 files.
340 - Fix an off-by-one bug in playlist handling.
341
342 --------------------------------------
343 0.2.16 (2007-04-05) "neural discharge"
344 --------------------------------------
345
346 The main change in this release is the major audio format handler
347 cleanup which removes some similar/duplicate code and makes it easier
348 to implement plugins for other audio formats. Of course, the usual mix
349 of other improvements/changes/bugfixes also made it into the release.
350
351 - simplified audio format handlers (most of the handling functions
352 were moved one layer up to the virtual streaming system).
353 - para_server uses mmap to read audio files
354 - repositioning of mp3 streams is much faster, in particular for
355 jumping near the end of large mp3 files.
356 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
357 and AFS_WRITE.
358 - fix a bug in para_filter that caused decoding of aac files
359 to start only after a few seconds.
360 - fix osx_writer hangs
361 - simplified dccp code (thanks to Gerrit Renker)
362 - the compress filter works also on big endian systems (ppc)
363
364 -----------------------------------------
365 0.2.15 (2007-02-16) "inductive resonance"
366 -----------------------------------------
367
368 Minor improvements, more documentation and a bunch of bug fixes.
369
370 - para_server: The server.users file is only read once on server
371 startup rather than for each connection
372 - mp3dec: Fix decoding of corrupt mp3 files
373 - afs (audio file sender) is now called vss (virtual streaming
374 system). Consequently, the permission flags specified in
375 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
376 become VSS_READ and VSS_WRITE respectively.
377 - para_audiod/para_filter: Fix a bug that caused the last chunk
378 of audio data not being written under certain circumstances
379 - audiod: compute the difference of server time and local time
380 correctly
381 - para_server/para_audiod: Fix some memory leaks
382 - documentation improvements
383 - configure.ac: fix checks for para_krell
384 - new man pages
385
386 -------------------------------------------
387 0.2.14 (2006-10-15) "transient singularity"
388 -------------------------------------------
389
390 The only major enhancement of this version is the osx writer which completes
391 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
392 until now for reasons beyond the scope of this changelog entry.
393
394 - new output plugin for Mac Os: the osx writer
395 - rename configure command line options from --enable-xxx-headers to
396 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
397 - configure: new command line options: --with-mad-headers,
398 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
399 - some robustness fixes
400 - dymamic audio format recognition for audiod
401 - para_server: new command line option: --autoplay_delay
402 - para_audiod: new command line option: --clock_diff_count
403
404 ---------------------------------------
405 0.2.13 (2006-07-14) "sonic convolution"
406 ---------------------------------------
407
408 A bunch of new features and core changes.
409
410 - the new paraslash scheduler, short and sweet.
411 - Support for m4a/mp4 files via the new aac audio format
412 handler/filter (requires libfaad).
413 - each writer has its own command line parser, just like
414 para_recv and para_filter.
415 - para_client and para_audioc use the error subsystem
416 - writers are integrated in para_audiod (currently linux-only)
417 - para_client is integrated in para_audiod
418 - random/playlist selector: improved info strings
419 - new audiod commands: tasks, kill
420 - update to libortp-0.10.1
421 - para_fade: wake time defaults to 8 hours from now
422 - update to autoconf-2.60
423
424
425 ------------------------------------------
426 0.2.12 (2006-05-12) "oriented abstraction"
427 ------------------------------------------
428
429 Many user-visible changes in this release and lots of new
430 features:
431
432
433 - the new optional dccp sender/receiver. It uses the datagram
434 congestion control protocol. You'll need a fairly new kernel
435 for this.
436 - paraslash works on Mac OS X (thanks to Gerd Becker)
437 - para_play renamed to para_write
438 - modular output plugin design (writers) for para_write
439 - new file_writer output plugin for para_write
440 - compress filter speed improvements
441 - update to libortp-0.9.1
442 - update to gengetopt-2.17rc
443 - para_client no longer depends on libreadline (as the
444 code for the interactive mode was removed).
445 - gcc-2-95 is no longer a supported compiler. It may still
446 work, but it gets no more testing.
447 - the tarball no longer contains the screenshot images which
448 reduces its size quite a bit.
449 - configure: new command line options: --enable-mysql-headers
450 and --enable-mysql-libs
451
452 ------------------------------------
453 0.2.11 (2006-03-11) "atomic duality"
454 ------------------------------------
455
456 Here it is, the first paraslash release developed with git. There
457 are fairly many user-visible changes in this release. As two out of
458 the three "database tools" of paraslash don't use a database at all,
459 they are now called "audio file selectors" instead.
460
461
462 - the cdt command (change database tool) becomes chs (change
463 selector)
464 - no more colon separators: The syntax of some options of
465 para_audiod and para_filter have changed. Use --help for
466 more info (and some examples).
467 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
468 - switch from cvs to git (should've done that earlier)
469 - the new ipc subsystem
470 - new audio file selector: playlist
471 - para_server: the dopey selector is now called "random",
472 and is the default selector. Use the --selector option to
473 choose another selector at startup, or the chs command to
474 change the selector at runtime.
475 - X86_64 fixes (thanks to Steffen Klassert)
476 - para_play fixes
477
478
479 --------------------------------------
480 0.2.10 (2006-02-17) "cyclic attractor"
481 --------------------------------------
482
483 Huge documentation update, a scrollable window for para_gui, ortp
484 improvements, and of course many small fixes not mentioned here.
485 The diffstat below is rather misleading as most insertions are due
486 to the new source documentation.
487
488 - autoconf cleanup
489 - para_server also uses the new error subsystem
490 - lots of new documentation (UTSL)
491 - gui improvements:
492 - keysyms for cursor keys and for next/previous page keys
493 - scrollable output window
494 - new internal commands: scroll up/down, page up/down
495 - fix color of command output.
496 - ortp: the --chunk_time and --header flags are no longer needed
497 for para_recv/para_audiod as this information is now encoded in
498 each rtp packet sent by para_server.
499
500
501 -------------------------------------------
502 0.2.9 (2006-01-24) "progressive turbulence"
503 -------------------------------------------
504
505 Internal audiod receivers/filters, the new error subsystem and
506 a lot of small improvements.
507
508 - para_recv and para_filter are integrated into the para_audiod
509 binary, i.e. audiod no longer spawns a new process for
510 each receiver/filter. As para_recv and para_filter might be
511 useful as standalone programs, they still get built (linked
512 against the same object files that are also used for audiod).
513 - further ortp timing improvements should reduce the CPU usage
514 of the ortp receiver.
515 - improved audio grabbing. The 'grab' command of para_audiod
516 has its own set of command line options. Read the output of
517 "para_audioc help grab" for more info.
518 - oggdec: configurable input prebuffer size.
519 - the new error subsystem gives better error diagnostics
520 and reduces code size.
521
522
523 -----------------------------------------
524 0.2.8 (2006-01-02) "dynamic accumulation"
525 -----------------------------------------
526
527 The new modular filter design and the para_play-hangs bugfix.
528
529 - new executable: para_filter. It combines para_mp3dec,
530 para_oggdec and para_compress. It also adds a further filter
531 type, wav, that just inserts a wave header at the desired point
532 of the filter chain. All 'piping' is done in-memory (i.e. no
533 read/write operations are used).
534 - para_play: fix a stupid bug that caused it to hang under
535 certain circumstances.
536
537
538 -------------------------------------------
539 0.2.7 (2006-12-27) "transparent invariance"
540 -------------------------------------------
541
542 Not many user-visible changes but a fair amount of internal improvements.
543
544
545 - The http sender buffers data if it can not be sent
546 out immediately (because the socket is not writable). This
547 should prevent para_server from shutting down the connection
548 too early on a loaded network.
549 - para_play also prebuffers data if it is told to start at a
550 future time by the --start_time option.
551 - The return of para_recv: It combines para_ortp_recv and
552 para_http_recv. Use the --receiver option to switch between
553 the two. para_recv builds without libortp, but contains
554 only the http receiver in this case.
555 - update to ortp 0.8.1. As this ortp release contains incompatible
556 changes, para_recv-0.2.7 won't link against older ortp libs.
557 - improved ortp timings.
558 - use of gcc-extensions that #define away for non-gcc and
559 gcc < 3.0.
560
561
562 -------------------------------------------
563 0.2.6 (2005-10-29) "recursive compensation"
564 -------------------------------------------
565
566 Transparent session encryption (uses openssl's Alleged RC4 cipher),
567 the internal find command and several other improvements and cleanups.
568
569 - Encrypt the session if encryption is requested by the client
570 (default for para_client 0.2.6). This is backwards
571 compatible, so older clients can still connect to para_server
572 0.2.6. Use the new client option --plain to request an
573 uncrypted session (off by default, must be set to on in
574 order to connect to para_server 0.2.x with 0 <= x <= 5).
575 - para_server uses an internal function to locate audio files
576 rather than calling find(1). The server option
577 --mysql_audio_file_dir replaces --mysql_find_cmd.
578 - documentation update
579 - man pages
580 - header file cleanup
581 - para_client code cleanup
582 - para_gui: faster display of output of display commands
583
584
585 ------------------------------------------
586 0.2.5 (2005-10-13) "aggressive resolution"
587 ------------------------------------------
588
589 This release adds internal senders, i.e. no more external programs are
590 spawned for sending out the audio data. There are two different senders
591 available: The http sender and the ortp sender (former para_send which
592 is no longer needed).
593
594 The new sender code has a plugin-like design so it can be easily
595 extended should there be be any future need for supporting another
596 network streaming protocol. All senders are completely independent of
597 each other. In particular, the http and the ortp sender can operate
598 in parallel.
599
600 - new server command: sender to control senders at runtime.
601 Read the output of "para_server -h" and "para_client help
602 sender" for more information.
603 - para_recv renamed to para_ortp_recv
604 - new executable: para_http_recv, a simple command line
605 http receiver.
606 - major afs/mp3/ogg code simplifications due to internal
607 senders.
608 - ogg timing improvements
609 - fix several minor memory leaks (found by valgrind)
610 - empty stream definitions work again
611 - com_ne(): ignore errors on remove
612 - audiod: fix segfault on server restart
613
614
615 ---------------------------------------
616 0.2.4 (2005-09-21) "toxic anticipation"
617 ---------------------------------------
618
619 Several small improvements, fixes and the new grab command.
620
621 - audiod:
622 - new command: "grab" to grab the output of the stream reader
623 or any filters. Read the output of "para_audioc help grab"
624 for more information.
625 - fix memory leak
626 - code cleanup
627 - audioc: new command line option: --bufsize to specify a
628 buffer size different from the default size 8192.
629 - improved error diagnostics for para_play.
630 - new configure option: --enable-ssldir so search for openssl in
631 non-standard places
632 - sdl_gui: Make it look nice again for 1024x768
633 - server: report total size of memory allocated with sbrk by malloc,
634 new command line option: --announce_time
635
636
637 -----------------------------------------
638 0.2.3 (2005-09-01) "hydrophilic movement"
639 -----------------------------------------
640
641 Two new executables and major feature enhancements.
642
643 - audiod filters: It is now possible to specify arbitrary many
644 (including none) filters for each supported audio
645 format. This can be used e.g. for normalizing volume,
646 transforming or grabbing the audio stream, or for using
647 visualizers. Read the output of "para_audiod -h" for the
648 syntax of the new --filter_cmd option.
649 - new executable: para_play, a tiny alsa player. It
650 can play wave files or raw pcm (16 bit little endian)
651 from stdin.
652 - new executable: para_compress, a dynamic range compressor
653 intended to keep audio output at a consistent volume. Derived
654 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
655 - audiod: New option: --stream_delay. This can be used in
656 a local network to syncronize the audio output of all
657 clients that play the same stream.
658
659
660 ------------------------------------------
661 0.2.2 (2005-08-19) "tangential excitation"
662 ------------------------------------------
663
664 Mostly internal changes in this release, but also some new commands
665 for the mysql database tool.
666
667 - cleanup exec.c, fix para_exec bug
668 - compile time loglevel (log messages below the given level
669 won't be compiled in, which reduces the size of the
670 resulting binaries)
671 - new log macros that shorten the size of the source code.
672 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
673 to send only zeros. With this workaround, para_audioc works
674 again.
675 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
676 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
677 (new entry), "snp" (set numplayed). Read the manual for more
678 information.
679
680
681 ---------------------------------------
682 0.2.1 (2005-08-15) "surreal experience"
683 ---------------------------------------
684
685 Here comes paraslash-0.2.1. It contains a couple of new features and,
686 surprise, only minor bug fixes.
687
688 - kill noisy mp3 debug message
689 - cleanup of the build system
690 - para_server and para_client directly use the crypto routines
691 of the openssl library rather than invoking the openssl command
692 line utitlity
693 - server/audiod: new option --user to switch to the given user
694 when invoked as root. Read the output of "para_server -h" for
695 more information.
696 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
697 status. Default: "para_audioc stat"
698 - sdl_gui: new option --pic_cmd to be used to download the picture.
699 Default: "para_client pic"
700 - audiod: 5 slots ought to be enough for everybody
701 - audiod: new status item: Uptime, kill hup command
702
703
704
705 ------------------------------------------
706 0.2.0 (2005-08-06) "distributed diffusion"
707 ------------------------------------------
708
709 After several month of increased development activity, paraslash-0.2.0
710 has arrived. It contains many new features and is much more
711 self-contained than the old 0.1.x series. Enjoy!
712
713
714 - para_server: fix hang on song change and crash on sighup.
715 Speed up mysql queries. The DIR_LIKE macro is gone.
716 - new executables: para_audiod, the local audio daemon that
717 starts playback (uses SCM_CREDENTIALS socket magic) and
718 para_audioc, the corresponding client.
719 - new executables: para_mp3dec/para_oggdec, two really teensy
720 decoders. para_mp3dec is based on libmad, para_oggdec requires
721 libvorbisfile.
722 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
723 they are now called para_send and para_recv respectively.
724 - documentation updates
725 - para_gui is themable. For now there is the default theme that
726 looks as before and the simple theme: blue and easy.
727 - gui: audio streaming is now handled by audiod. Time display shows
728 playback time rather than streaming time
729 - slider: update to libzmw-0.2.0
730 - para_krell: fix crash on server shutdown
731 - switch from gzip to bzip2
732
733
734 ----------------------------------------
735 0.1.7 (2005-04-18) "melting penetration"
736 ----------------------------------------
737
738 The main change in this release is clearly the oggvorbis rewrite,
739 but there are also lots of smaller changes. If you intend to use both
740 the mp3 and the ogg plugin, it is recommended to use software mixing,
741 e.g. the dmix plugin which is provided by ALSA.
742
743 - new executables: para_ovsend and para_ovrecv for sending/receiving
744 oggvorbis files via rtp. Requires the open rtp library. Get it at
745 http://www.linphone.org/ortp/
746 - rewrite of the ogg_vorbis core code
747 - configure detects libzmw and, if detected, includes
748 para_slider to the list of binaries to be built by make
749 - server stream writers read from their associated fifo rather
750 than from stdin
751 - slider: two new sliders, lastplayed and numplayed
752 - fix nasty double free bug which caused random segfaults in case of
753 mp3 files with invalid header information
754 - gui: new command line option: --stream_timeout=seconds to
755 deactivate a slot if it is idle for that many seconds (default=`5')
756 - diffstats
757
758
759 ---------------------------------------
760 0.1.6 (2005-03-05) "asymptotic balance"
761 ---------------------------------------
762
763 Only little user-visible changes in this release. Mainly bugfixes and
764 core code cleanup. This is probably the most stable version ever if you
765 stick to mp3...
766
767 - fix several memory leaks
768 - rename default name of mysql database from "music" to "paraslash".
769 Use para_server's --mysql_database option if you do not want to
770 rename your old database.
771 - rework ogg vorbis code
772 - make update command work on mysql servers with LOCAL_INFILE
773 disabled
774 - gui: improved stream I/O (slots)
775 - simplified audio format API
776 - para_pob_ogg is gone
777
778 ------------------------------------
779 0.1.5 (2004-12-31) "opaque eternity"
780 ------------------------------------
781
782 Let's slide gently into the new year.
783
784 - new: para_slider (not built automatically, type "make
785 para_slider" to build). A toy for those who always felt that
786 creating stream definitions is difficult. See screenshots,
787 README and FEATURES for more info.
788 - improved signal handling. Fixes server segfault on SIGHUP
789 for linux kernels newer than Aug 24 2004 and makes para_gui
790 race-free.
791 - reload database tool on SIGHUP
792 - improved help message for sl
793 - do not log "broken pipe" messages as errors. They are
794 perfectly ok.
795 - fix wrong error message on permission errors
796
797 -----------------------------------------
798 0.1.4 (2004-12-19) "tunneling transition"
799 -----------------------------------------
800
801 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
802 Hopefully, most of them got wiped out with this release. Some
803 enhancements went also in.
804
805 - improved error diagnostics for all commands
806 - stradd/picadd: overwrite previous contents if entry already
807 exists, rather than returning errors
808 - stradd: use current stream if invoked without args
809 - faster (and hopefully more stable) ogg-vorbis handling
810 - para_krell: reap children to avoid zombie-flooding in case
811 no server is running
812 - si: report also server pid
813 - server: don't busy-loop if dbtool reports only invalid files.
814 - gui: CTRL+C works again, fix stream_read command line option
815 - fix pic_add, hist
816 - fix mysql dbtool startup in case no database exists
817 - many small fixes and cleanups
818
819 ---------------------------------------
820 0.1.3: (2004-12-10) "vanishing inertia"
821 ---------------------------------------
822
823 Starting from this release, the database tools are integrated in the
824 server binary. This decreases server startup time, reduces code size
825 and speeds up database commands. However, the layout of the underlying
826 mysql database changed only slightly and 0.1.3 should be backwards
827 compatible in that respect.
828
829 Visible changes:
830
831 - If mysql is not detected at compile time, or fails to init
832 at runtime, fall back to the dopey database tool which should
833 always work.
834 - para_dbtool and dbtool.conf are gone. All mysql specific
835 options are read from server.conf and are prefixed by 'mysql_'.
836 - new command: cdt (change database tool)
837 - new command line option: dbtool (choose startup database tool)
838 - The name of current stream is now stored in the database,
839 so paraslash remembers its current stream when restarted.
840 - new command: csp (change stream and play)
841 - para_gui also reports current database tool and server uptime
842
843
844 -------------------------------------------
845 0.1.2: (2004-11-28) "spherical fluctuation"
846 -------------------------------------------
847
848 Point release before the big dbtool changes go in.
849
850 - dbtool: rename ca to cam (copy all meta data). It now also
851 copies numplayed and lastplayed time as well as the picture
852 id.
853 - fix endless-loop-bug caused by mp3 files with invalid header
854
855 -----------------------------------------
856 0.1.1: (2004-11-05) "floating atmosphere"
857 -----------------------------------------
858
859 - gkrellm plugin
860 - new dbtool command: mbox. Browse your sound-file collection
861 with your favorite mail reader.
862 - several small fixes
863
864 -------------------------------------
865 0.1.0: (2204-10-22) "rotating cortex"
866 -------------------------------------
867
868 - fix logging bug for loglevel > VERBOSE
869 - fix skip command
870 - correct timings for vbr mp3s
871 - modular audio format support
872 - ogg-vorbis support (experimental)
873 - new server option: autoplay
874
875 -----------------------------------------
876 0.0.99: (2004-07-25) "harmonic deviation"
877 -----------------------------------------
878
879 - rename projectname from icc to paraslash (play, archive, rate
880 and stream large audio sets happily)
881 - paraslash is no longer restricted to one particular audio
882 streaming software
883 - new dbtool commands (stradd, strq, strdel) for easy stream
884 managment w/o configuration file. That obsoletes stream_defs
885 file/config option for dbtool.
886 - picadd accepts jpeg data from stdin
887 - new server commands: ps (select previous stream), sc (song change)
888 - new default pictures for sdl_gui
889 - gui: new key_map option for binding commands and internal
890 functions to arbitrary keys, nice help screen, rip out
891 soundcard/linux specific stuff, avoid noise artefacts while jumping,
892 show silly logo on startup
893 - new executables: para_fade for fading volume, para_dbadm for
894 manipulating attributes
895 - cdb adds _all_ tables to mysql database
896 - revised and beautified documentation
897 - sample dbtool rewritten in C
898 - autoconf
899
900 ---------------------------------------------
901 0.0.98: (2003-12-26) "incremental smoothness"
902 ---------------------------------------------
903
904 - kick icecast in favour of poc. That removes some races and reduces
905 core code considerably.
906 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
907 give finer info on afs' status.
908 - gui can start decoder (see config options). Further new gui
909 commands: refresh (^L), jmp (F1-F10)
910 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
911 terminates gui. This fixes dead instances consuming memory
912 continuously.
913 - new dbtool command: verb for sending verbatim sql queries.
914 - fix pid_list races (by removing pid_list)
915 - codename funnies
916
917 --------------------
918 0.0.97: (2003-10-26)
919 --------------------
920
921 - installation prefix now defaults to /usr/local
922 - new commands for gui: snozze, sleep and reread config
923 - config file for gui and sdl_gui
924 - fix problems with filenames containing funny characters
925 (reported by Thomas Forell)
926 - improved signal handling for gui, now it rereads conf on SIGHUP
927 - new dbtool command: cdb (create database)
928 - switch from argtable to gengetopt
929 - major code cleanup and speed improvements
930 - fix several potential buffer overflows
931 - many small fixes and cleanups

935 -------------------
936
937 - easy stream_defs syntax
938 - sdl_gui can display images associated to the file being played
939 - Major feature enhancements for icc_gui including dynamic text
940 placement and the top/bottom window design

942 well as for invalid picture pointers
943 - fix long outstanding case sensitivity bug
944 - many small fixes and cleanups
945
946 -------------------
947 0.0.95 (2003-06-29)
948 -------------------
949
950 - sdl gui runs much faster
951 - new dbtool command: ca (copy attributes)
952 - count and display number of times the song has been played

956 - decrease network traffic of stat
957 - fix zombie bug
958 - many small fixes and cleanups
959
960 -------------------

974 -------------------
975
976 - colors for icc_gui
977 - icc_gui sets volume directly (linux only)
978 - proper locking that fixes some races
979 - fix security bug that caused commands to be executed even
980 with unsufficient permissions
981 - new command: hup to make all servers reread their configuration file
