Merge branch 't/flac'
[paraslash.git] / NEWS
1 ------------------------------------------
2 0.4.9 (to be announced) "hybrid causality"
3 ------------------------------------------
4
5 Support for another audio format and many small improvements/fixes
6 all over the place.
7
8 - Support for flac, the free lossless audio codec.
9 - Fix for an endless loop in the mp3 decoder for certain
10 (corrupt) mp3 files.
11 - autogen.sh now detects a distcc setup and adjusts the
12 parameter for the -j option of make accordingly.
13 - Shared memory areas are no longer restricted to 64K. We now
14 detect the maximal size of a shared memory area at runtime.
15 - cleanup of the internal uptime API.
16 - para_server prefaults the mmapped audio file to avoid
17 delays on slow media.
18 - A new test for the test-suite that exercises the
19 communication between para_server and para_audiod.
20 - The alsa writer eats up less CPU cycles when configured to
21 use the DMIX plugin.
22 - Simplified and unified receiver code.
23 - Makefile cleanups.
24 - Commands which print a list of matching audio files now
25 emit a meaningful error message if no audio file matched the
26 given pattern(s).
27
28 --------------------------------------
29 0.4.8 (2011-08-19) "nested assignment"
30 --------------------------------------
31
32 Gcrypt support, the overhauled osx writer and regex format specifiers
33 are the highlights of this release.
34
35 - support for libgcrypt as a drop-in replacement for openssl.
36 Run configure --enable-cryptolib=gcrypt to link against
37 libgcrypt. The two crypto implementations are compatible to
38 each other, i.e. a para_client executable linked against
39 gcrypt can connect to para_server linked against libssl
40 and vice versa.
41 - Rewrite of the osx writer (output plugin for Mac OS).
42 - audiod: The format specifier for receivers, filters and
43 writers is now treated as a regular expression. This allows
44 to replace 5 lines in the config file (one for each audio
45 format) by one single line. See the manual for details.
46 - The *.cmdline.[ch] files are no longer contained in the released
47 tarballs. This reduces the size of the tarballs but requires
48 gengetopt to build the tarball.
49 - Compiles cleanly also with llvm/clang.
50 - Corrupt mp3 files are handled more gracefully.
51 - The alsa writer uses poll fds instead of computing timeouts.
52 - Cleanup of the generic writer API.
53 - sched: Optimized zero timeouts.
54 - vss timeout cleanups.
55 - oggdec fixes and improvements.
56
57 --------------------------------------
58 0.4.7 (2011-06-01) "infinite rollback"
59 --------------------------------------
60
61 The new ao writer, support for ssh RSA keys and a couple of other
62 enhancements.
63
64 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
65 platforms through the libao audio library.
66 - Support for RSA keys generated with ssh-keygen.
67 - configure: improved options for ogg/vorbis/speex.
68 - The git version reported by --version always matches HEAD.
69 - The autogen script detects the number of processors and
70 runs a parallel make if possible.
71 - Major cleanup of the crypto API.
72 - Documentation updates.
73
74 ------------------------------------------
75 0.4.6 (2011-03-31) "deterministic entropy"
76 ------------------------------------------
77
78 Lots of ogg/vorbis improvements, the new test suite, enhancements
79 for para_gui and a fair amount of other bug fixes.
80
81 - For DCCP/OGG streams the audio file header is only sent once
82 at the beginning of the stream rather than periodically
83 every five seconds. This reduces network traffic and the
84 FEC group size.
85 - The vorbis comment header is replaced by an empty dummy header
86 before the header is sent over the network. This also results in
87 less network traffic and smaller FEC groups.
88 - The new "test" make target allows to perform some sanity checks prior
89 to installing the package.
90 - ogg timing fixes and performance improvements
91 - Scheduler improvements
92 - Proper exit codes for para_write
93 - para_gui: New option --theme to select a startup theme. Several
94 other improvements and fixes.
95 - aacdec error message cleanups
96 - simplified color error handling
97
98 --------------------------------------------
99 0.4.5 (2010-12-17) "symmetric randomization"
100 --------------------------------------------
101
102 Bug fixes, internal cleanups and variable-sized FEC slices.
103
104 - Contains a fix for an invalid-free-bug in the ogg audio format
105 handler code.
106 - Switching off the DCCP sender works again.
107 - para_audiod handles crashes of para_server more robustly.
108 - Internal scheduler and writer cleanups.
109 - Reduced latency due to variable-sized FEC slices.
110 - Improved documentation and error diagnostics.
111 - The build of para_server is now optional, allowing the build
112 to succeed in case libosl is not installed.
113
114 ------------------------------------------
115 0.4.4 (2010-08-06) "persistent regularity"
116 ------------------------------------------
117
118 Support for yet another audio format, para_write improvements and
119 bug fixes.
120
121 - Support for the speex codec.
122 - Support for sample formats other than 16 bit little endian.
123 - error2.h is now created by a perl script which speeds up configure
124 considerably.
125 - Fix a bug in the aac decoder which could lead to segfaults in
126 para_filter/para_audiod.
127 - Fixes for autoconf-2.66.
128
129 ----------------------------------------
130 0.4.3 (2010-07-05) "imaginary radiation"
131 ----------------------------------------
132
133 Many improvements for the DCCP and the UDP transport, the new user
134 manual and the usual mix of bug fixes and internal improvements.
135
136 - FEC support for the DCCP sender (Gerrit Renker). The new
137 --dccp_max_slice_size, --dccp_data_slices_per_group and
138 --dccp_slices_per_group options can be used to set the FEC
139 parameters for the DCCP transport.
140 - DNS lookups for UDP targets (Gerrit Renker).
141 - The new user manual replaces the README, README.afs, REQUIREMENTS
142 and INSTALL documents.
143 - Fix an end-of-file detection bug in the oggdec filter.
144 - The new nonblock API.
145 - Both options of the oggdec filter have been removed.
146 - New debug mode for the internal scheduler.
147
148 ------------------------------------------
149 0.4.2 (2010-04-23) "associative expansion"
150 ------------------------------------------
151
152 It's been some time since the last release, but finally here is
153 paraslash-0.4.2. The bulk of the changes comes from the new buffer
154 tree API, but there are changes all over the tree. Mainly performance
155 and usability improvements, but also quite some bug fixes.
156
157 - The new buffer tree API.
158 - DCCP: Support for CCID negotiation (Gerrit Renker).
159 - UDP robustness fixes.
160 - The --bufsize option for mp3dec is gone as it no longer makes sense
161 for the new buffer tree API.
162 - Fix audible buffer underruns for wma streams.
163 - The alsa writer no longer prints meaningless underrun durations.
164 - audiod: Defaults work also for udp streams. If no filter is
165 given for an audio format that is received via upd, fecdec is
166 automatically added as the first filter (along with the decoder).
167
168 ---------------------------------------
169 0.4.1 (2009-12-22) "concurrent horizon"
170 ---------------------------------------
171
172 Support for another audio format, minor feature enhancements and lots of bug
173 fixes. All fixes that have been accumulated in the maint branch (in particular
174 those mentionened in the 0.3.6 release notes) appear in this release as well.
175
176 - wma support.
177 - new afh option: --human to activate human-readable output.
178 - new server/audiod option: --log-timing to print timing information.
179 - build system improvements.
180 - source code documentation updates.
181
182 -------------------------------------
183 0.3.6 (2009-12-07) "cubic continuity"
184 -------------------------------------
185
186 Quite a few bugs have been found and fixed since 0.3.5, so here's
187 another 0.3.x release. No new features.
188
189 - Always check return value of malloc().
190 - ogg vorbis/FEC: Do not write garbage after the audio file header.
191 - exit if root privileges could not be dropped.
192 - FEC: Fix computation of extra slices.
193 - oss: Fix check for empty input buffer.
194 - Avoid buffer underruns due to filter chain output buffer constraints.
195 - server: Fix assignment of afs_pid.
196 - Don't panic if the afs database contains unknown audio formats.
197 - http/dccp: Do not send the audio file header twice.
198 - FEC: Timing improvements.
199
200 ----------------------------------------------
201 0.4.0 (2009-11-10) "simultaneous independence"
202 ----------------------------------------------
203
204 Two significant changes which require the new version number: The
205 improved authentication dialog and the fact that the database code
206 has been moved to a library, libosl. To use the new version, you have
207 to generate new RSA keys, see INSTALL for details. A shell script is
208 provided for conversion of the 0.3 database to the new 0.4 format.
209
210 - stronger crypto for client authentication
211 - the database code has been moved to a library
212 - improved status item handling
213 - cleanup of the build system
214 - The "-V" option now also prints the git version
215 - the new parser-friendly listing mode for the ls and stat commands
216 - mandatory rc4 encryption
217 - major audio format handler cleanups
218 - (id3,...) tags are no longer stored as a combined string in the database
219 - new mood methods: artist_matches, title_matches, comment_matches,
220 album_matches, year_maches, year.
221
222 --------------------------------------------
223 0.3.5 (2009-09-21) "symplectic separability"
224 --------------------------------------------
225
226 Full client support for *BSD Unixes, complete re-write of the ogg
227 vorbis audio format handler, various improvements all over the place
228 and the usual mix of bugfixes. This release marks the end of the 0.3
229 series if no serious problems show up.
230
231 - the new oss writer (supported on *BSD and Linux)
232 - rewrite of the ogg vorbis audio format handler. It's
233 recommended to replace the chunk tables of existing ogg
234 vorbis files in the afs database by re-adding these files
235 with "add -f".
236 - support for netmask subsets (Gerrit Renker)
237 - the new prebuffer filter
238 - improved signal handling
239 - variable fec output buffer size
240 - improved FEC timing fixes audible buffer underruns in UDP mode
241 - --log_color actually works
242 - new ls option: -d (print dates as seconds after the epoch)
243 - update to gengetopt 2.22.2
244 - support for RSA keys of size > 512 bits
245 - new option "mixer_channel" for para_fade
246
247 -----------------------------------------
248 0.3.4 (2009-05-07) "elliptic inheritance"
249 -----------------------------------------
250
251 The new udp sender, forward error correction, colored logs and various
252 other improvements. As the udp sender does not depend on any special
253 libraries, it is built unconditionally.
254
255 - The udp sender replaces the ortp sender. The new code uses forward
256 error correction to protect against packet losses. Many thanks to
257 Gerrit Renker for providing ipv6 support.
258 - The default port for udp streaming now defaults to 8000, like
259 for the http and the dccp senders/receivers.
260 - Loglevels are now specified as symbolic names, e.g.
261 "--loglevel info".
262 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
263 - para_server/para_audiod: Color support for log messages.
264 - new options for mp3dec: --ignore-crc, --bufsize
265 - new audiod option: --config-file.
266 - gengetopt cleanups.
267 - Improved help/man pages: The documentation of para_audiod,
268 para_recv, para_filter and para_write now also contains
269 all options of the available receivers/filters/writers. The
270 man page of para_fade contains a description of the different
271 modes of operation.
272 - More source code documentation.
273 - vss timing fixes.
274
275 --------------------------------------------
276 0.3.3 (2008-12-01) "axiomatic perspectivity"
277 --------------------------------------------
278
279 Internal code cleanups, bug fixes, improved tag handling and the new
280 amplification filter.
281
282 - para_server uses the generic scheduling code.
283 - overhaul of the virtual streaming system.
284 - mp3: id3 version 2 support via libid3tag (optional)
285 - ogg: vorbis comment support.
286 - aac meta info support.
287 - mp3 audio format handler cleanups.
288 - new filter: "amp" to amplify the amplitude of the audio stream
289 - new status item/database entry: amplification. It is
290 used by the amp filter to pre-amplify the audio stream.
291 - fix a close-without-open bug in para_write.
292 - fix a bug in com_init() which was introduced in 0.3.2.
293 - better error diagnostics for para_client.
294
295 -----------------------------------------
296 0.3.2 (2008-04-11) "probabilistic parity"
297 -----------------------------------------
298
299 The new para_afh executable, scheduling and documentation improvements.
300
301 - new ls option: -lc (list chunk table)
302 - new executable: para_afh, the stand-alone audio file handler tool
303 - afs commands can send output more than SHMMAX (32MB on Linux). This
304 also reduces the memory usage of commands that produce large amounts
305 of output.
306 - major scheduler and audiod cleanups.
307 - more detailed and much nicer man pages.
308
309 ---------------------------------------
310 0.3.1 (2008-02-23) "liquid interaction"
311 ---------------------------------------
312
313 A mix of cleanups, bug fixes, improvements, and some new features. No
314 significant changes to the new database (osl) code, which is generally
315 a good sign.
316
317 - Share some similar/duplicate code between the http and the
318 dccp sender.
319 - Generic access control lists for paraslash senders.
320 - dccp sender: Access control lists, connection limiting and support
321 for the allow,deny,on,off,help sender commands.
322 - The default dccp port changed from 5001 to 8000 (suggested by
323 Gerrit Renker).
324 - para_server starts even if not all public keys could be loaded.
325 - Audiod performance improvements.
326 - fix a bug in the "off" command of the http sender.
327 - fix some fd and memory leaks.
328 - Update to gengetopt-2.22.
329
330 -------------------------------------
331 0.3.0 (2008-01-12) "solar saturation"
332 -------------------------------------
333
334 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
335
336
337 Usually one might expect lots of new features AND a big increase in size
338 for a major release like this.
339
340 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
341 ever. The decrease in size is mostly due to the removal of some
342 graphical tools (which were only quick hacks anyway). But also the
343 fact that the mysql code is gone cuts down the size a bit.
344
345 Being independent of mysql comes at a cost: The fact that paraslash
346 now contains its own database (the object storage layer, osl) increases
347 the (stripped) binary size of para_server by ~50K on i386.
348
349 - no more restrictions on unique basenames.
350 - independent of mysql: The new self-contained object
351 storage layer (osl) replaces the mysql database.
352 - New executable para_fsck: Check integrity of osl tables.
353 - Lyrics support.
354 - Reliable audio file move/rename detection.
355 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
356 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
357 Solaris (sparc64).
358 - the new osl-based audio file selector (afs) replaces the random,
359 the playlist and the mysql selector of paraslash-0.2.x.
360 - IPv6 support (thanks to Gerrit Renker).
361 - paraslash-0.2.x streams are now called "moods". Writing
362 0.3.x-mood definitions should be both easier and more
363 powerful than writing 0.2.x-stream definitions.
364 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
365 been removed. The world is a better place without them. However,
366 para_gui is still there.
367 - afs tracks audio file selection also in playlist mode.
368 - few easy-to-use afs commands replace the many not-so-easy-to-use
369 mysql commands (and are available also in playlist mode).
370 - Improved error subsystem.
371 - The earth-shaking new logo.
372
373 -----------------------------------------
374 0.2.17 (2007-11-20) "isotropic threshold"
375 -----------------------------------------
376
377 Mainly bugfixes and cleanups in this version which marks the end of
378 the 0.2.x series if no serious bugs show up after the release.
379
380 - mysql_selector: fix a locking bug.
381 - universal chunk queueing.
382 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
383 to Gerrit Renker).
384 - be more carful wrt. signed vs. unsigned argument passing.
385 - cleanup error.h and fix some references to invalid error
386 codes.
387 - update to gengetopt-2.21.
388 - update to ortp-0.13.1.
389 - autoconf: extend checks for headers, library functions and
390 compiler characteristics.
391 - Fix streaming of large mp3 files.
392 - Fix an off-by-one bug in playlist handling.
393
394 --------------------------------------
395 0.2.16 (2007-04-05) "neural discharge"
396 --------------------------------------
397
398 The main change in this release is the major audio format handler
399 cleanup which removes some similar/duplicate code and makes it easier
400 to implement plugins for other audio formats. Of course, the usual mix
401 of other improvements/changes/bugfixes also made it into the release.
402
403 - simplified audio format handlers (most of the handling functions
404 were moved one layer up to the virtual streaming system).
405 - para_server uses mmap to read audio files
406 - repositioning of mp3 streams is much faster, in particular for
407 jumping near the end of large mp3 files.
408 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
409 and AFS_WRITE.
410 - fix a bug in para_filter that caused decoding of aac files
411 to start only after a few seconds.
412 - fix osx_writer hangs
413 - simplified dccp code (thanks to Gerrit Renker)
414 - the compress filter works also on big endian systems (ppc)
415
416 -----------------------------------------
417 0.2.15 (2007-02-16) "inductive resonance"
418 -----------------------------------------
419
420 Minor improvements, more documentation and a bunch of bug fixes.
421
422 - para_server: The server.users file is only read once on server
423 startup rather than for each connection
424 - mp3dec: Fix decoding of corrupt mp3 files
425 - afs (audio file sender) is now called vss (virtual streaming
426 system). Consequently, the permission flags specified in
427 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
428 become VSS_READ and VSS_WRITE respectively.
429 - para_audiod/para_filter: Fix a bug that caused the last chunk
430 of audio data not being written under certain circumstances
431 - audiod: compute the difference of server time and local time
432 correctly
433 - para_server/para_audiod: Fix some memory leaks
434 - documentation improvements
435 - configure.ac: fix checks for para_krell
436 - new man pages
437
438 -------------------------------------------
439 0.2.14 (2006-10-15) "transient singularity"
440 -------------------------------------------
441
442 The only major enhancement of this version is the osx writer which completes
443 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
444 until now for reasons beyond the scope of this changelog entry.
445
446 - new output plugin for Mac Os: the osx writer
447 - rename configure command line options from --enable-xxx-headers to
448 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
449 - configure: new command line options: --with-mad-headers,
450 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
451 - some robustness fixes
452 - dymamic audio format recognition for audiod
453 - para_server: new command line option: --autoplay_delay
454 - para_audiod: new command line option: --clock_diff_count
455
456 ---------------------------------------
457 0.2.13 (2006-07-14) "sonic convolution"
458 ---------------------------------------
459
460 A bunch of new features and core changes.
461
462 - the new paraslash scheduler, short and sweet.
463 - Support for m4a/mp4 files via the new aac audio format
464 handler/filter (requires libfaad).
465 - each writer has its own command line parser, just like
466 para_recv and para_filter.
467 - para_client and para_audioc use the error subsystem
468 - writers are integrated in para_audiod (currently linux-only)
469 - para_client is integrated in para_audiod
470 - random/playlist selector: improved info strings
471 - new audiod commands: tasks, kill
472 - update to libortp-0.10.1
473 - para_fade: wake time defaults to 8 hours from now
474 - update to autoconf-2.60
475
476
477 ------------------------------------------
478 0.2.12 (2006-05-12) "oriented abstraction"
479 ------------------------------------------
480
481 Many user-visible changes in this release and lots of new
482 features:
483
484
485 - the new optional dccp sender/receiver. It uses the datagram
486 congestion control protocol. You'll need a fairly new kernel
487 for this.
488 - paraslash works on Mac OS X (thanks to Gerd Becker)
489 - para_play renamed to para_write
490 - modular output plugin design (writers) for para_write
491 - new file_writer output plugin for para_write
492 - compress filter speed improvements
493 - update to libortp-0.9.1
494 - update to gengetopt-2.17rc
495 - para_client no longer depends on libreadline (as the
496 code for the interactive mode was removed).
497 - gcc-2-95 is no longer a supported compiler. It may still
498 work, but it gets no more testing.
499 - the tarball no longer contains the screenshot images which
500 reduces its size quite a bit.
501 - configure: new command line options: --enable-mysql-headers
502 and --enable-mysql-libs
503
504 ------------------------------------
505 0.2.11 (2006-03-11) "atomic duality"
506 ------------------------------------
507
508 Here it is, the first paraslash release developed with git. There
509 are fairly many user-visible changes in this release. As two out of
510 the three "database tools" of paraslash don't use a database at all,
511 they are now called "audio file selectors" instead.
512
513
514 - the cdt command (change database tool) becomes chs (change
515 selector)
516 - no more colon separators: The syntax of some options of
517 para_audiod and para_filter have changed. Use --help for
518 more info (and some examples).
519 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
520 - switch from cvs to git (should've done that earlier)
521 - the new ipc subsystem
522 - new audio file selector: playlist
523 - para_server: the dopey selector is now called "random",
524 and is the default selector. Use the --selector option to
525 choose another selector at startup, or the chs command to
526 change the selector at runtime.
527 - X86_64 fixes (thanks to Steffen Klassert)
528 - para_play fixes
529
530
531 --------------------------------------
532 0.2.10 (2006-02-17) "cyclic attractor"
533 --------------------------------------
534
535 Huge documentation update, a scrollable window for para_gui, ortp
536 improvements, and of course many small fixes not mentioned here.
537 The diffstat below is rather misleading as most insertions are due
538 to the new source documentation.
539
540 - autoconf cleanup
541 - para_server also uses the new error subsystem
542 - lots of new documentation (UTSL)
543 - gui improvements:
544 - keysyms for cursor keys and for next/previous page keys
545 - scrollable output window
546 - new internal commands: scroll up/down, page up/down
547 - fix color of command output.
548 - ortp: the --chunk_time and --header flags are no longer needed
549 for para_recv/para_audiod as this information is now encoded in
550 each rtp packet sent by para_server.
551
552
553 -------------------------------------------
554 0.2.9 (2006-01-24) "progressive turbulence"
555 -------------------------------------------
556
557 Internal audiod receivers/filters, the new error subsystem and
558 a lot of small improvements.
559
560 - para_recv and para_filter are integrated into the para_audiod
561 binary, i.e. audiod no longer spawns a new process for
562 each receiver/filter. As para_recv and para_filter might be
563 useful as standalone programs, they still get built (linked
564 against the same object files that are also used for audiod).
565 - further ortp timing improvements should reduce the CPU usage
566 of the ortp receiver.
567 - improved audio grabbing. The 'grab' command of para_audiod
568 has its own set of command line options. Read the output of
569 "para_audioc help grab" for more info.
570 - oggdec: configurable input prebuffer size.
571 - the new error subsystem gives better error diagnostics
572 and reduces code size.
573
574
575 -----------------------------------------
576 0.2.8 (2006-01-02) "dynamic accumulation"
577 -----------------------------------------
578
579 The new modular filter design and the para_play-hangs bugfix.
580
581 - new executable: para_filter. It combines para_mp3dec,
582 para_oggdec and para_compress. It also adds a further filter
583 type, wav, that just inserts a wave header at the desired point
584 of the filter chain. All 'piping' is done in-memory (i.e. no
585 read/write operations are used).
586 - para_play: fix a stupid bug that caused it to hang under
587 certain circumstances.
588
589
590 -------------------------------------------
591 0.2.7 (2006-12-27) "transparent invariance"
592 -------------------------------------------
593
594 Not many user-visible changes but a fair amount of internal improvements.
595
596
597 - The http sender buffers data if it can not be sent
598 out immediately (because the socket is not writable). This
599 should prevent para_server from shutting down the connection
600 too early on a loaded network.
601 - para_play also prebuffers data if it is told to start at a
602 future time by the --start_time option.
603 - The return of para_recv: It combines para_ortp_recv and
604 para_http_recv. Use the --receiver option to switch between
605 the two. para_recv builds without libortp, but contains
606 only the http receiver in this case.
607 - update to ortp 0.8.1. As this ortp release contains incompatible
608 changes, para_recv-0.2.7 won't link against older ortp libs.
609 - improved ortp timings.
610 - use of gcc-extensions that #define away for non-gcc and
611 gcc < 3.0.
612
613
614 -------------------------------------------
615 0.2.6 (2005-10-29) "recursive compensation"
616 -------------------------------------------
617
618 Transparent session encryption (uses openssl's Alleged RC4 cipher),
619 the internal find command and several other improvements and cleanups.
620
621 - Encrypt the session if encryption is requested by the client
622 (default for para_client 0.2.6). This is backwards
623 compatible, so older clients can still connect to para_server
624 0.2.6. Use the new client option --plain to request an
625 uncrypted session (off by default, must be set to on in
626 order to connect to para_server 0.2.x with 0 <= x <= 5).
627 - para_server uses an internal function to locate audio files
628 rather than calling find(1). The server option
629 --mysql_audio_file_dir replaces --mysql_find_cmd.
630 - documentation update
631 - man pages
632 - header file cleanup
633 - para_client code cleanup
634 - para_gui: faster display of output of display commands
635
636
637 ------------------------------------------
638 0.2.5 (2005-10-13) "aggressive resolution"
639 ------------------------------------------
640
641 This release adds internal senders, i.e. no more external programs are
642 spawned for sending out the audio data. There are two different senders
643 available: The http sender and the ortp sender (former para_send which
644 is no longer needed).
645
646 The new sender code has a plugin-like design so it can be easily
647 extended should there be be any future need for supporting another
648 network streaming protocol. All senders are completely independent of
649 each other. In particular, the http and the ortp sender can operate
650 in parallel.
651
652 - new server command: sender to control senders at runtime.
653 Read the output of "para_server -h" and "para_client help
654 sender" for more information.
655 - para_recv renamed to para_ortp_recv
656 - new executable: para_http_recv, a simple command line
657 http receiver.
658 - major afs/mp3/ogg code simplifications due to internal
659 senders.
660 - ogg timing improvements
661 - fix several minor memory leaks (found by valgrind)
662 - empty stream definitions work again
663 - com_ne(): ignore errors on remove
664 - audiod: fix segfault on server restart
665
666
667 ---------------------------------------
668 0.2.4 (2005-09-21) "toxic anticipation"
669 ---------------------------------------
670
671 Several small improvements, fixes and the new grab command.
672
673 - audiod:
674 - new command: "grab" to grab the output of the stream reader
675 or any filters. Read the output of "para_audioc help grab"
676 for more information.
677 - fix memory leak
678 - code cleanup
679 - audioc: new command line option: --bufsize to specify a
680 buffer size different from the default size 8192.
681 - improved error diagnostics for para_play.
682 - new configure option: --enable-ssldir so search for openssl in
683 non-standard places
684 - sdl_gui: Make it look nice again for 1024x768
685 - server: report total size of memory allocated with sbrk by malloc,
686 new command line option: --announce_time
687
688
689 -----------------------------------------
690 0.2.3 (2005-09-01) "hydrophilic movement"
691 -----------------------------------------
692
693 Two new executables and major feature enhancements.
694
695 - audiod filters: It is now possible to specify arbitrary many
696 (including none) filters for each supported audio
697 format. This can be used e.g. for normalizing volume,
698 transforming or grabbing the audio stream, or for using
699 visualizers. Read the output of "para_audiod -h" for the
700 syntax of the new --filter_cmd option.
701 - new executable: para_play, a tiny alsa player. It
702 can play wave files or raw pcm (16 bit little endian)
703 from stdin.
704 - new executable: para_compress, a dynamic range compressor
705 intended to keep audio output at a consistent volume. Derived
706 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
707 - audiod: New option: --stream_delay. This can be used in
708 a local network to syncronize the audio output of all
709 clients that play the same stream.
710
711
712 ------------------------------------------
713 0.2.2 (2005-08-19) "tangential excitation"
714 ------------------------------------------
715
716 Mostly internal changes in this release, but also some new commands
717 for the mysql database tool.
718
719 - cleanup exec.c, fix para_exec bug
720 - compile time loglevel (log messages below the given level
721 won't be compiled in, which reduces the size of the
722 resulting binaries)
723 - new log macros that shorten the size of the source code.
724 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
725 to send only zeros. With this workaround, para_audioc works
726 again.
727 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
728 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
729 (new entry), "snp" (set numplayed). Read the manual for more
730 information.
731
732
733 ---------------------------------------
734 0.2.1 (2005-08-15) "surreal experience"
735 ---------------------------------------
736
737 Here comes paraslash-0.2.1. It contains a couple of new features and,
738 surprise, only minor bug fixes.
739
740 - kill noisy mp3 debug message
741 - cleanup of the build system
742 - para_server and para_client directly use the crypto routines
743 of the openssl library rather than invoking the openssl command
744 line utitlity
745 - server/audiod: new option --user to switch to the given user
746 when invoked as root. Read the output of "para_server -h" for
747 more information.
748 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
749 status. Default: "para_audioc stat"
750 - sdl_gui: new option --pic_cmd to be used to download the picture.
751 Default: "para_client pic"
752 - audiod: 5 slots ought to be enough for everybody
753 - audiod: new status item: Uptime, kill hup command
754
755
756
757 ------------------------------------------
758 0.2.0 (2005-08-06) "distributed diffusion"
759 ------------------------------------------
760
761 After several month of increased development activity, paraslash-0.2.0
762 has arrived. It contains many new features and is much more
763 self-contained than the old 0.1.x series. Enjoy!
764
765
766 - para_server: fix hang on song change and crash on sighup.
767 Speed up mysql queries. The DIR_LIKE macro is gone.
768 - new executables: para_audiod, the local audio daemon that
769 starts playback (uses SCM_CREDENTIALS socket magic) and
770 para_audioc, the corresponding client.
771 - new executables: para_mp3dec/para_oggdec, two really teensy
772 decoders. para_mp3dec is based on libmad, para_oggdec requires
773 libvorbisfile.
774 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
775 they are now called para_send and para_recv respectively.
776 - documentation updates
777 - para_gui is themable. For now there is the default theme that
778 looks as before and the simple theme: blue and easy.
779 - gui: audio streaming is now handled by audiod. Time display shows
780 playback time rather than streaming time
781 - slider: update to libzmw-0.2.0
782 - para_krell: fix crash on server shutdown
783 - switch from gzip to bzip2
784
785
786 ----------------------------------------
787 0.1.7 (2005-04-18) "melting penetration"
788 ----------------------------------------
789
790 The main change in this release is clearly the oggvorbis rewrite,
791 but there are also lots of smaller changes. If you intend to use both
792 the mp3 and the ogg plugin, it is recommended to use software mixing,
793 e.g. the dmix plugin which is provided by ALSA.
794
795 - new executables: para_ovsend and para_ovrecv for sending/receiving
796 oggvorbis files via rtp. Requires the open rtp library. Get it at
797 http://www.linphone.org/ortp/
798 - rewrite of the ogg_vorbis core code
799 - configure detects libzmw and, if detected, includes
800 para_slider to the list of binaries to be built by make
801 - server stream writers read from their associated fifo rather
802 than from stdin
803 - slider: two new sliders, lastplayed and numplayed
804 - fix nasty double free bug which caused random segfaults in case of
805 mp3 files with invalid header information
806 - gui: new command line option: --stream_timeout=seconds to
807 deactivate a slot if it is idle for that many seconds (default=`5')
808 - diffstats
809
810
811 ---------------------------------------
812 0.1.6 (2005-03-05) "asymptotic balance"
813 ---------------------------------------
814
815 Only little user-visible changes in this release. Mainly bugfixes and
816 core code cleanup. This is probably the most stable version ever if you
817 stick to mp3...
818
819 - fix several memory leaks
820 - rename default name of mysql database from "music" to "paraslash".
821 Use para_server's --mysql_database option if you do not want to
822 rename your old database.
823 - rework ogg vorbis code
824 - make update command work on mysql servers with LOCAL_INFILE
825 disabled
826 - gui: improved stream I/O (slots)
827 - simplified audio format API
828 - para_pob_ogg is gone
829
830 ------------------------------------
831 0.1.5 (2004-12-31) "opaque eternity"
832 ------------------------------------
833
834 Let's slide gently into the new year.
835
836 - new: para_slider (not built automatically, type "make
837 para_slider" to build). A toy for those who always felt that
838 creating stream definitions is difficult. See screenshots,
839 README and FEATURES for more info.
840 - improved signal handling. Fixes server segfault on SIGHUP
841 for linux kernels newer than Aug 24 2004 and makes para_gui
842 race-free.
843 - reload database tool on SIGHUP
844 - improved help message for sl
845 - do not log "broken pipe" messages as errors. They are
846 perfectly ok.
847 - fix wrong error message on permission errors
848
849 -----------------------------------------
850 0.1.4 (2004-12-19) "tunneling transition"
851 -----------------------------------------
852
853 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
854 Hopefully, most of them got wiped out with this release. Some
855 enhancements went also in.
856
857 - improved error diagnostics for all commands
858 - stradd/picadd: overwrite previous contents if entry already
859 exists, rather than returning errors
860 - stradd: use current stream if invoked without args
861 - faster (and hopefully more stable) ogg-vorbis handling
862 - para_krell: reap children to avoid zombie-flooding in case
863 no server is running
864 - si: report also server pid
865 - server: don't busy-loop if dbtool reports only invalid files.
866 - gui: CTRL+C works again, fix stream_read command line option
867 - fix pic_add, hist
868 - fix mysql dbtool startup in case no database exists
869 - many small fixes and cleanups
870
871 ---------------------------------------
872 0.1.3: (2004-12-10) "vanishing inertia"
873 ---------------------------------------
874
875 Starting from this release, the database tools are integrated in the
876 server binary. This decreases server startup time, reduces code size
877 and speeds up database commands. However, the layout of the underlying
878 mysql database changed only slightly and 0.1.3 should be backwards
879 compatible in that respect.
880
881 Visible changes:
882
883 - If mysql is not detected at compile time, or fails to init
884 at runtime, fall back to the dopey database tool which should
885 always work.
886 - para_dbtool and dbtool.conf are gone. All mysql specific
887 options are read from server.conf and are prefixed by 'mysql_'.
888 - new command: cdt (change database tool)
889 - new command line option: dbtool (choose startup database tool)
890 - The name of current stream is now stored in the database,
891 so paraslash remembers its current stream when restarted.
892 - new command: csp (change stream and play)
893 - para_gui also reports current database tool and server uptime
894
895
896 -------------------------------------------
897 0.1.2: (2004-11-28) "spherical fluctuation"
898 -------------------------------------------
899
900 Point release before the big dbtool changes go in.
901
902 - dbtool: rename ca to cam (copy all meta data). It now also
903 copies numplayed and lastplayed time as well as the picture
904 id.
905 - fix endless-loop-bug caused by mp3 files with invalid header
906
907 -----------------------------------------
908 0.1.1: (2004-11-05) "floating atmosphere"
909 -----------------------------------------
910
911 - gkrellm plugin
912 - new dbtool command: mbox. Browse your sound-file collection
913 with your favorite mail reader.
914 - several small fixes
915
916 -------------------------------------
917 0.1.0: (2204-10-22) "rotating cortex"
918 -------------------------------------
919
920 - fix logging bug for loglevel > VERBOSE
921 - fix skip command
922 - correct timings for vbr mp3s
923 - modular audio format support
924 - ogg-vorbis support (experimental)
925 - new server option: autoplay
926
927 -----------------------------------------
928 0.0.99: (2004-07-25) "harmonic deviation"
929 -----------------------------------------
930
931 - rename projectname from icc to paraslash (play, archive, rate
932 and stream large audio sets happily)
933 - paraslash is no longer restricted to one particular audio
934 streaming software
935 - new dbtool commands (stradd, strq, strdel) for easy stream
936 managment w/o configuration file. That obsoletes stream_defs
937 file/config option for dbtool.
938 - picadd accepts jpeg data from stdin
939 - new server commands: ps (select previous stream), sc (song change)
940 - new default pictures for sdl_gui
941 - gui: new key_map option for binding commands and internal
942 functions to arbitrary keys, nice help screen, rip out
943 soundcard/linux specific stuff, avoid noise artefacts while jumping,
944 show silly logo on startup
945 - new executables: para_fade for fading volume, para_dbadm for
946 manipulating attributes
947 - cdb adds _all_ tables to mysql database
948 - revised and beautified documentation
949 - sample dbtool rewritten in C
950 - autoconf
951
952 ---------------------------------------------
953 0.0.98: (2003-12-26) "incremental smoothness"
954 ---------------------------------------------
955
956 - kick icecast in favour of poc. That removes some races and reduces
957 core code considerably.
958 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
959 give finer info on afs' status.
960 - gui can start decoder (see config options). Further new gui
961 commands: refresh (^L), jmp (F1-F10)
962 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
963 terminates gui. This fixes dead instances consuming memory
964 continuously.
965 - new dbtool command: verb for sending verbatim sql queries.
966 - fix pid_list races (by removing pid_list)
967 - codename funnies
968
969 --------------------
970 0.0.97: (2003-10-26)
971 --------------------
972
973 - installation prefix now defaults to /usr/local
974 - new commands for gui: snozze, sleep and reread config
975 - config file for gui and sdl_gui
976 - fix problems with filenames containing funny characters
977 (reported by Thomas Forell)
978 - improved signal handling for gui, now it rereads conf on SIGHUP
979 - new dbtool command: cdb (create database)
980 - switch from argtable to gengetopt
981 - major code cleanup and speed improvements
982 - fix several potential buffer overflows
983 - many small fixes and cleanups

994 well as for invalid picture pointers
995 - fix long outstanding case sensitivity bug
996 - many small fixes and cleanups
997
998 -------------------

1002 - sdl gui runs much faster
1003 - new dbtool command: ca (copy attributes)
1004 - count and display number of times the song has been played
1005 - new feature: scoring
1006 - command line options for sdl_gui
1007 - simpler syntax of streams file
1008 - decrease network traffic of stat
1009 - fix zombie bug
1010 - many small fixes and cleanups
1011
1012 -------------------
1013 0.0.94 (2003-05-04)
1014 -------------------
1015
1016 - new server command: ns (next stream)

1022 - many small fixes and cleanups
1023
1024 -------------------
1025 0.0.93 (2003-03-28)
1026 -------------------
1027
1028 - colors for icc_gui
1029 - icc_gui sets volume directly (linux only)
1030 - proper locking that fixes some races
1031 - fix security bug that caused commands to be executed even
1032 with unsufficient permissions
1033 - new command: hup to make all servers reread their configuration file
1034 - icecast meta data streaming
1035 - many small fixes and cleanups
