audioc: Improve documentation of main().
[paraslash.git] / NEWS
1 -----------------------------------------------
2 0.4.10 (to be announced) "heterogeneous vacuum"
3 -----------------------------------------------
4
5 -------------------------------------
6 0.4.9 (2011-12-06) "hybrid causality"
7 -------------------------------------
8
9 Support for another audio format, interactive mode for para_client
10 and para_audiod and many small improvements/fixes all over the place.
11
12 - Support for flac, the free lossless audio codec.
13 - Fix for an endless loop in the mp3 decoder for certain
14 (corrupt) mp3 files.
15 - When executed without specifying a command, para_client
16 and para_audioc start an interactive shell (requires
17 libreadline being installed). The interactive mode offers
18 full tab completion and command line history.
19 - autogen.sh now detects a distcc setup and adjusts the
20 parameter for the -j option of make accordingly.
21 - Shared memory areas are no longer restricted to 64K. We now
22 detect the maximal size of a shared memory area at runtime.
23 - cleanup of the internal uptime API.
24 - para_server prefaults the mmapped audio file to avoid
25 delays on slow media.
26 - A new test for the test-suite that exercises the
27 communication between para_server and para_audiod.
28 - The alsa writer eats up less CPU cycles when configured to
29 use the DMIX plugin.
30 - Simplified and unified receiver code.
31 - Makefile cleanups.
32 - Commands which print a list of matching audio files now
33 emit a meaningful error message if no audio file matched the
34 given pattern(s).
35
36 --------------------------------------
37 0.4.8 (2011-08-19) "nested assignment"
38 --------------------------------------
39
40 Gcrypt support, the overhauled osx writer and regex format specifiers
41 are the highlights of this release.
42
43 - support for libgcrypt as a drop-in replacement for openssl.
44 Run configure --enable-cryptolib=gcrypt to link against
45 libgcrypt. The two crypto implementations are compatible to
46 each other, i.e. a para_client executable linked against
47 gcrypt can connect to para_server linked against libssl
48 and vice versa.
49 - Rewrite of the osx writer (output plugin for Mac OS).
50 - audiod: The format specifier for receivers, filters and
51 writers is now treated as a regular expression. This allows
52 to replace 5 lines in the config file (one for each audio
53 format) by one single line. See the manual for details.
54 - The *.cmdline.[ch] files are no longer contained in the released
55 tarballs. This reduces the size of the tarballs but requires
56 gengetopt to build the tarball.
57 - Compiles cleanly also with llvm/clang.
58 - Corrupt mp3 files are handled more gracefully.
59 - The alsa writer uses poll fds instead of computing timeouts.
60 - Cleanup of the generic writer API.
61 - sched: Optimized zero timeouts.
62 - vss timeout cleanups.
63 - oggdec fixes and improvements.
64
65 --------------------------------------
66 0.4.7 (2011-06-01) "infinite rollback"
67 --------------------------------------
68
69 The new ao writer, support for ssh RSA keys and a couple of other
70 enhancements.
71
72 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
73 platforms through the libao audio library.
74 - Support for RSA keys generated with ssh-keygen.
75 - configure: improved options for ogg/vorbis/speex.
76 - The git version reported by --version always matches HEAD.
77 - The autogen script detects the number of processors and
78 runs a parallel make if possible.
79 - Major cleanup of the crypto API.
80 - Documentation updates.
81
82 ------------------------------------------
83 0.4.6 (2011-03-31) "deterministic entropy"
84 ------------------------------------------
85
86 Lots of ogg/vorbis improvements, the new test suite, enhancements
87 for para_gui and a fair amount of other bug fixes.
88
89 - For DCCP/OGG streams the audio file header is only sent once
90 at the beginning of the stream rather than periodically
91 every five seconds. This reduces network traffic and the
92 FEC group size.
93 - The vorbis comment header is replaced by an empty dummy header
94 before the header is sent over the network. This also results in
95 less network traffic and smaller FEC groups.
96 - The new "test" make target allows to perform some sanity checks prior
97 to installing the package.
98 - ogg timing fixes and performance improvements
99 - Scheduler improvements
100 - Proper exit codes for para_write
101 - para_gui: New option --theme to select a startup theme. Several
102 other improvements and fixes.
103 - aacdec error message cleanups
104 - simplified color error handling
105
106 --------------------------------------------
107 0.4.5 (2010-12-17) "symmetric randomization"
108 --------------------------------------------
109
110 Bug fixes, internal cleanups and variable-sized FEC slices.
111
112 - Contains a fix for an invalid-free-bug in the ogg audio format
113 handler code.
114 - Switching off the DCCP sender works again.
115 - para_audiod handles crashes of para_server more robustly.
116 - Internal scheduler and writer cleanups.
117 - Reduced latency due to variable-sized FEC slices.
118 - Improved documentation and error diagnostics.
119 - The build of para_server is now optional, allowing the build
120 to succeed in case libosl is not installed.
121
122 ------------------------------------------
123 0.4.4 (2010-08-06) "persistent regularity"
124 ------------------------------------------
125
126 Support for yet another audio format, para_write improvements and
127 bug fixes.
128
129 - Support for the speex codec.
130 - Support for sample formats other than 16 bit little endian.
131 - error2.h is now created by a perl script which speeds up configure
132 considerably.
133 - Fix a bug in the aac decoder which could lead to segfaults in
134 para_filter/para_audiod.
135 - Fixes for autoconf-2.66.
136
137 ----------------------------------------
138 0.4.3 (2010-07-05) "imaginary radiation"
139 ----------------------------------------
140
141 Many improvements for the DCCP and the UDP transport, the new user
142 manual and the usual mix of bug fixes and internal improvements.
143
144 - FEC support for the DCCP sender (Gerrit Renker). The new
145 --dccp_max_slice_size, --dccp_data_slices_per_group and
146 --dccp_slices_per_group options can be used to set the FEC
147 parameters for the DCCP transport.
148 - DNS lookups for UDP targets (Gerrit Renker).
149 - The new user manual replaces the README, README.afs, REQUIREMENTS
150 and INSTALL documents.
151 - Fix an end-of-file detection bug in the oggdec filter.
152 - The new nonblock API.
153 - Both options of the oggdec filter have been removed.
154 - New debug mode for the internal scheduler.
155
156 ------------------------------------------
157 0.4.2 (2010-04-23) "associative expansion"
158 ------------------------------------------
159
160 It's been some time since the last release, but finally here is
161 paraslash-0.4.2. The bulk of the changes comes from the new buffer
162 tree API, but there are changes all over the tree. Mainly performance
163 and usability improvements, but also quite some bug fixes.
164
165 - The new buffer tree API.
166 - DCCP: Support for CCID negotiation (Gerrit Renker).
167 - UDP robustness fixes.
168 - The --bufsize option for mp3dec is gone as it no longer makes sense
169 for the new buffer tree API.
170 - Fix audible buffer underruns for wma streams.
171 - The alsa writer no longer prints meaningless underrun durations.
172 - audiod: Defaults work also for udp streams. If no filter is
173 given for an audio format that is received via upd, fecdec is
174 automatically added as the first filter (along with the decoder).
175
176 ---------------------------------------
177 0.4.1 (2009-12-22) "concurrent horizon"
178 ---------------------------------------
179
180 Support for another audio format, minor feature enhancements and lots of bug
181 fixes. All fixes that have been accumulated in the maint branch (in particular
182 those mentionened in the 0.3.6 release notes) appear in this release as well.
183
184 - wma support.
185 - new afh option: --human to activate human-readable output.
186 - new server/audiod option: --log-timing to print timing information.
187 - build system improvements.
188 - source code documentation updates.
189
190 -------------------------------------
191 0.3.6 (2009-12-07) "cubic continuity"
192 -------------------------------------
193
194 Quite a few bugs have been found and fixed since 0.3.5, so here's
195 another 0.3.x release. No new features.
196
197 - Always check return value of malloc().
198 - ogg vorbis/FEC: Do not write garbage after the audio file header.
199 - exit if root privileges could not be dropped.
200 - FEC: Fix computation of extra slices.
201 - oss: Fix check for empty input buffer.
202 - Avoid buffer underruns due to filter chain output buffer constraints.
203 - server: Fix assignment of afs_pid.
204 - Don't panic if the afs database contains unknown audio formats.
205 - http/dccp: Do not send the audio file header twice.
206 - FEC: Timing improvements.
207
208 ----------------------------------------------
209 0.4.0 (2009-11-10) "simultaneous independence"
210 ----------------------------------------------
211
212 Two significant changes which require the new version number: The
213 improved authentication dialog and the fact that the database code
214 has been moved to a library, libosl. To use the new version, you have
215 to generate new RSA keys, see INSTALL for details. A shell script is
216 provided for conversion of the 0.3 database to the new 0.4 format.
217
218 - stronger crypto for client authentication
219 - the database code has been moved to a library
220 - improved status item handling
221 - cleanup of the build system
222 - The "-V" option now also prints the git version
223 - the new parser-friendly listing mode for the ls and stat commands
224 - mandatory rc4 encryption
225 - major audio format handler cleanups
226 - (id3,...) tags are no longer stored as a combined string in the database
227 - new mood methods: artist_matches, title_matches, comment_matches,
228 album_matches, year_maches, year.
229
230 --------------------------------------------
231 0.3.5 (2009-09-21) "symplectic separability"
232 --------------------------------------------
233
234 Full client support for *BSD Unixes, complete re-write of the ogg
235 vorbis audio format handler, various improvements all over the place
236 and the usual mix of bugfixes. This release marks the end of the 0.3
237 series if no serious problems show up.
238
239 - the new oss writer (supported on *BSD and Linux)
240 - rewrite of the ogg vorbis audio format handler. It's
241 recommended to replace the chunk tables of existing ogg
242 vorbis files in the afs database by re-adding these files
243 with "add -f".
244 - support for netmask subsets (Gerrit Renker)
245 - the new prebuffer filter
246 - improved signal handling
247 - variable fec output buffer size
248 - improved FEC timing fixes audible buffer underruns in UDP mode
249 - --log_color actually works
250 - new ls option: -d (print dates as seconds after the epoch)
251 - update to gengetopt 2.22.2
252 - support for RSA keys of size > 512 bits
253 - new option "mixer_channel" for para_fade
254
255 -----------------------------------------
256 0.3.4 (2009-05-07) "elliptic inheritance"
257 -----------------------------------------
258
259 The new udp sender, forward error correction, colored logs and various
260 other improvements. As the udp sender does not depend on any special
261 libraries, it is built unconditionally.
262
263 - The udp sender replaces the ortp sender. The new code uses forward
264 error correction to protect against packet losses. Many thanks to
265 Gerrit Renker for providing ipv6 support.
266 - The default port for udp streaming now defaults to 8000, like
267 for the http and the dccp senders/receivers.
268 - Loglevels are now specified as symbolic names, e.g.
269 "--loglevel info".
270 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
271 - para_server/para_audiod: Color support for log messages.
272 - new options for mp3dec: --ignore-crc, --bufsize
273 - new audiod option: --config-file.
274 - gengetopt cleanups.
275 - Improved help/man pages: The documentation of para_audiod,
276 para_recv, para_filter and para_write now also contains
277 all options of the available receivers/filters/writers. The
278 man page of para_fade contains a description of the different
279 modes of operation.
280 - More source code documentation.
281 - vss timing fixes.
282
283 --------------------------------------------
284 0.3.3 (2008-12-01) "axiomatic perspectivity"
285 --------------------------------------------
286
287 Internal code cleanups, bug fixes, improved tag handling and the new
288 amplification filter.
289
290 - para_server uses the generic scheduling code.
291 - overhaul of the virtual streaming system.
292 - mp3: id3 version 2 support via libid3tag (optional)
293 - ogg: vorbis comment support.
294 - aac meta info support.
295 - mp3 audio format handler cleanups.
296 - new filter: "amp" to amplify the amplitude of the audio stream
297 - new status item/database entry: amplification. It is
298 used by the amp filter to pre-amplify the audio stream.
299 - fix a close-without-open bug in para_write.
300 - fix a bug in com_init() which was introduced in 0.3.2.
301 - better error diagnostics for para_client.
302
303 -----------------------------------------
304 0.3.2 (2008-04-11) "probabilistic parity"
305 -----------------------------------------
306
307 The new para_afh executable, scheduling and documentation improvements.
308
309 - new ls option: -lc (list chunk table)
310 - new executable: para_afh, the stand-alone audio file handler tool
311 - afs commands can send output more than SHMMAX (32MB on Linux). This
312 also reduces the memory usage of commands that produce large amounts
313 of output.
314 - major scheduler and audiod cleanups.
315 - more detailed and much nicer man pages.
316
317 ---------------------------------------
318 0.3.1 (2008-02-23) "liquid interaction"
319 ---------------------------------------
320
321 A mix of cleanups, bug fixes, improvements, and some new features. No
322 significant changes to the new database (osl) code, which is generally
323 a good sign.
324
325 - Share some similar/duplicate code between the http and the
326 dccp sender.
327 - Generic access control lists for paraslash senders.
328 - dccp sender: Access control lists, connection limiting and support
329 for the allow,deny,on,off,help sender commands.
330 - The default dccp port changed from 5001 to 8000 (suggested by
331 Gerrit Renker).
332 - para_server starts even if not all public keys could be loaded.
333 - Audiod performance improvements.
334 - fix a bug in the "off" command of the http sender.
335 - fix some fd and memory leaks.
336 - Update to gengetopt-2.22.
337
338 -------------------------------------
339 0.3.0 (2008-01-12) "solar saturation"
340 -------------------------------------
341
342 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
343
344
345 Usually one might expect lots of new features AND a big increase in size
346 for a major release like this.
347
348 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
349 ever. The decrease in size is mostly due to the removal of some
350 graphical tools (which were only quick hacks anyway). But also the
351 fact that the mysql code is gone cuts down the size a bit.
352
353 Being independent of mysql comes at a cost: The fact that paraslash
354 now contains its own database (the object storage layer, osl) increases
355 the (stripped) binary size of para_server by ~50K on i386.
356
357 - no more restrictions on unique basenames.
358 - independent of mysql: The new self-contained object
359 storage layer (osl) replaces the mysql database.
360 - New executable para_fsck: Check integrity of osl tables.
361 - Lyrics support.
362 - Reliable audio file move/rename detection.
363 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
364 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
365 Solaris (sparc64).
366 - the new osl-based audio file selector (afs) replaces the random,
367 the playlist and the mysql selector of paraslash-0.2.x.
368 - IPv6 support (thanks to Gerrit Renker).
369 - paraslash-0.2.x streams are now called "moods". Writing
370 0.3.x-mood definitions should be both easier and more
371 powerful than writing 0.2.x-stream definitions.
372 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
373 been removed. The world is a better place without them. However,
374 para_gui is still there.
375 - afs tracks audio file selection also in playlist mode.
376 - few easy-to-use afs commands replace the many not-so-easy-to-use
377 mysql commands (and are available also in playlist mode).
378 - Improved error subsystem.
379 - The earth-shaking new logo.
380
381 -----------------------------------------
382 0.2.17 (2007-11-20) "isotropic threshold"
383 -----------------------------------------
384
385 Mainly bugfixes and cleanups in this version which marks the end of
386 the 0.2.x series if no serious bugs show up after the release.
387
388 - mysql_selector: fix a locking bug.
389 - universal chunk queueing.
390 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
391 to Gerrit Renker).
392 - be more carful wrt. signed vs. unsigned argument passing.
393 - cleanup error.h and fix some references to invalid error
394 codes.
395 - update to gengetopt-2.21.
396 - update to ortp-0.13.1.
397 - autoconf: extend checks for headers, library functions and
398 compiler characteristics.
399 - Fix streaming of large mp3 files.
400 - Fix an off-by-one bug in playlist handling.
401
402 --------------------------------------
403 0.2.16 (2007-04-05) "neural discharge"
404 --------------------------------------
405
406 The main change in this release is the major audio format handler
407 cleanup which removes some similar/duplicate code and makes it easier
408 to implement plugins for other audio formats. Of course, the usual mix
409 of other improvements/changes/bugfixes also made it into the release.
410
411 - simplified audio format handlers (most of the handling functions
412 were moved one layer up to the virtual streaming system).
413 - para_server uses mmap to read audio files
414 - repositioning of mp3 streams is much faster, in particular for
415 jumping near the end of large mp3 files.
416 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
417 and AFS_WRITE.
418 - fix a bug in para_filter that caused decoding of aac files
419 to start only after a few seconds.
420 - fix osx_writer hangs
421 - simplified dccp code (thanks to Gerrit Renker)
422 - the compress filter works also on big endian systems (ppc)
423
424 -----------------------------------------
425 0.2.15 (2007-02-16) "inductive resonance"
426 -----------------------------------------
427
428 Minor improvements, more documentation and a bunch of bug fixes.
429
430 - para_server: The server.users file is only read once on server
431 startup rather than for each connection
432 - mp3dec: Fix decoding of corrupt mp3 files
433 - afs (audio file sender) is now called vss (virtual streaming
434 system). Consequently, the permission flags specified in
435 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
436 become VSS_READ and VSS_WRITE respectively.
437 - para_audiod/para_filter: Fix a bug that caused the last chunk
438 of audio data not being written under certain circumstances
439 - audiod: compute the difference of server time and local time
440 correctly
441 - para_server/para_audiod: Fix some memory leaks
442 - documentation improvements
443 - configure.ac: fix checks for para_krell
444 - new man pages
445
446 -------------------------------------------
447 0.2.14 (2006-10-15) "transient singularity"
448 -------------------------------------------
449
450 The only major enhancement of this version is the osx writer which completes
451 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
452 until now for reasons beyond the scope of this changelog entry.
453
454 - new output plugin for Mac Os: the osx writer
455 - rename configure command line options from --enable-xxx-headers to
456 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
457 - configure: new command line options: --with-mad-headers,
458 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
459 - some robustness fixes
460 - dymamic audio format recognition for audiod
461 - para_server: new command line option: --autoplay_delay
462 - para_audiod: new command line option: --clock_diff_count
463
464 ---------------------------------------
465 0.2.13 (2006-07-14) "sonic convolution"
466 ---------------------------------------
467
468 A bunch of new features and core changes.
469
470 - the new paraslash scheduler, short and sweet.
471 - Support for m4a/mp4 files via the new aac audio format
472 handler/filter (requires libfaad).
473 - each writer has its own command line parser, just like
474 para_recv and para_filter.
475 - para_client and para_audioc use the error subsystem
476 - writers are integrated in para_audiod (currently linux-only)
477 - para_client is integrated in para_audiod
478 - random/playlist selector: improved info strings
479 - new audiod commands: tasks, kill
480 - update to libortp-0.10.1
481 - para_fade: wake time defaults to 8 hours from now
482 - update to autoconf-2.60
483
484
485 ------------------------------------------
486 0.2.12 (2006-05-12) "oriented abstraction"
487 ------------------------------------------
488
489 Many user-visible changes in this release and lots of new
490 features:
491
492
493 - the new optional dccp sender/receiver. It uses the datagram
494 congestion control protocol. You'll need a fairly new kernel
495 for this.
496 - paraslash works on Mac OS X (thanks to Gerd Becker)
497 - para_play renamed to para_write
498 - modular output plugin design (writers) for para_write
499 - new file_writer output plugin for para_write
500 - compress filter speed improvements
501 - update to libortp-0.9.1
502 - update to gengetopt-2.17rc
503 - para_client no longer depends on libreadline (as the
504 code for the interactive mode was removed).
505 - gcc-2-95 is no longer a supported compiler. It may still
506 work, but it gets no more testing.
507 - the tarball no longer contains the screenshot images which
508 reduces its size quite a bit.
509 - configure: new command line options: --enable-mysql-headers
510 and --enable-mysql-libs
511
512 ------------------------------------
513 0.2.11 (2006-03-11) "atomic duality"
514 ------------------------------------
515
516 Here it is, the first paraslash release developed with git. There
517 are fairly many user-visible changes in this release. As two out of
518 the three "database tools" of paraslash don't use a database at all,
519 they are now called "audio file selectors" instead.
520
521
522 - the cdt command (change database tool) becomes chs (change
523 selector)
524 - no more colon separators: The syntax of some options of
525 para_audiod and para_filter have changed. Use --help for
526 more info (and some examples).
527 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
528 - switch from cvs to git (should've done that earlier)
529 - the new ipc subsystem
530 - new audio file selector: playlist
531 - para_server: the dopey selector is now called "random",
532 and is the default selector. Use the --selector option to
533 choose another selector at startup, or the chs command to
534 change the selector at runtime.
535 - X86_64 fixes (thanks to Steffen Klassert)
536 - para_play fixes
537
538
539 --------------------------------------
540 0.2.10 (2006-02-17) "cyclic attractor"
541 --------------------------------------
542
543 Huge documentation update, a scrollable window for para_gui, ortp
544 improvements, and of course many small fixes not mentioned here.
545 The diffstat below is rather misleading as most insertions are due
546 to the new source documentation.
547
548 - autoconf cleanup
549 - para_server also uses the new error subsystem
550 - lots of new documentation (UTSL)
551 - gui improvements:
552 - keysyms for cursor keys and for next/previous page keys
553 - scrollable output window
554 - new internal commands: scroll up/down, page up/down
555 - fix color of command output.
556 - ortp: the --chunk_time and --header flags are no longer needed
557 for para_recv/para_audiod as this information is now encoded in
558 each rtp packet sent by para_server.
559
560
561 -------------------------------------------
562 0.2.9 (2006-01-24) "progressive turbulence"
563 -------------------------------------------
564
565 Internal audiod receivers/filters, the new error subsystem and
566 a lot of small improvements.
567
568 - para_recv and para_filter are integrated into the para_audiod
569 binary, i.e. audiod no longer spawns a new process for
570 each receiver/filter. As para_recv and para_filter might be
571 useful as standalone programs, they still get built (linked
572 against the same object files that are also used for audiod).
573 - further ortp timing improvements should reduce the CPU usage
574 of the ortp receiver.
575 - improved audio grabbing. The 'grab' command of para_audiod
576 has its own set of command line options. Read the output of
577 "para_audioc help grab" for more info.
578 - oggdec: configurable input prebuffer size.
579 - the new error subsystem gives better error diagnostics
580 and reduces code size.
581
582
583 -----------------------------------------
584 0.2.8 (2006-01-02) "dynamic accumulation"
585 -----------------------------------------
586
587 The new modular filter design and the para_play-hangs bugfix.
588
589 - new executable: para_filter. It combines para_mp3dec,
590 para_oggdec and para_compress. It also adds a further filter
591 type, wav, that just inserts a wave header at the desired point
592 of the filter chain. All 'piping' is done in-memory (i.e. no
593 read/write operations are used).
594 - para_play: fix a stupid bug that caused it to hang under
595 certain circumstances.
596
597
598 -------------------------------------------
599 0.2.7 (2006-12-27) "transparent invariance"
600 -------------------------------------------
601
602 Not many user-visible changes but a fair amount of internal improvements.
603
604
605 - The http sender buffers data if it can not be sent
606 out immediately (because the socket is not writable). This
607 should prevent para_server from shutting down the connection
608 too early on a loaded network.
609 - para_play also prebuffers data if it is told to start at a
610 future time by the --start_time option.
611 - The return of para_recv: It combines para_ortp_recv and
612 para_http_recv. Use the --receiver option to switch between
613 the two. para_recv builds without libortp, but contains
614 only the http receiver in this case.
615 - update to ortp 0.8.1. As this ortp release contains incompatible
616 changes, para_recv-0.2.7 won't link against older ortp libs.
617 - improved ortp timings.
618 - use of gcc-extensions that #define away for non-gcc and
619 gcc < 3.0.
620
621
622 -------------------------------------------
623 0.2.6 (2005-10-29) "recursive compensation"
624 -------------------------------------------
625
626 Transparent session encryption (uses openssl's Alleged RC4 cipher),
627 the internal find command and several other improvements and cleanups.
628
629 - Encrypt the session if encryption is requested by the client
630 (default for para_client 0.2.6). This is backwards
631 compatible, so older clients can still connect to para_server
632 0.2.6. Use the new client option --plain to request an
633 uncrypted session (off by default, must be set to on in
634 order to connect to para_server 0.2.x with 0 <= x <= 5).
635 - para_server uses an internal function to locate audio files
636 rather than calling find(1). The server option
637 --mysql_audio_file_dir replaces --mysql_find_cmd.
638 - documentation update
639 - man pages
640 - header file cleanup
641 - para_client code cleanup
642 - para_gui: faster display of output of display commands
643
644
645 ------------------------------------------
646 0.2.5 (2005-10-13) "aggressive resolution"
647 ------------------------------------------
648
649 This release adds internal senders, i.e. no more external programs are
650 spawned for sending out the audio data. There are two different senders
651 available: The http sender and the ortp sender (former para_send which
652 is no longer needed).
653
654 The new sender code has a plugin-like design so it can be easily
655 extended should there be be any future need for supporting another
656 network streaming protocol. All senders are completely independent of
657 each other. In particular, the http and the ortp sender can operate
658 in parallel.
659
660 - new server command: sender to control senders at runtime.
661 Read the output of "para_server -h" and "para_client help
662 sender" for more information.
663 - para_recv renamed to para_ortp_recv
664 - new executable: para_http_recv, a simple command line
665 http receiver.
666 - major afs/mp3/ogg code simplifications due to internal
667 senders.
668 - ogg timing improvements
669 - fix several minor memory leaks (found by valgrind)
670 - empty stream definitions work again
671 - com_ne(): ignore errors on remove
672 - audiod: fix segfault on server restart
673
674
675 ---------------------------------------
676 0.2.4 (2005-09-21) "toxic anticipation"
677 ---------------------------------------
678
679 Several small improvements, fixes and the new grab command.
680
681 - audiod:
682 - new command: "grab" to grab the output of the stream reader
683 or any filters. Read the output of "para_audioc help grab"
684 for more information.
685 - fix memory leak
686 - code cleanup
687 - audioc: new command line option: --bufsize to specify a
688 buffer size different from the default size 8192.
689 - improved error diagnostics for para_play.
690 - new configure option: --enable-ssldir so search for openssl in
691 non-standard places
692 - sdl_gui: Make it look nice again for 1024x768
693 - server: report total size of memory allocated with sbrk by malloc,
694 new command line option: --announce_time
695
696
697 -----------------------------------------
698 0.2.3 (2005-09-01) "hydrophilic movement"
699 -----------------------------------------
700
701 Two new executables and major feature enhancements.
702
703 - audiod filters: It is now possible to specify arbitrary many
704 (including none) filters for each supported audio
705 format. This can be used e.g. for normalizing volume,
706 transforming or grabbing the audio stream, or for using
707 visualizers. Read the output of "para_audiod -h" for the
708 syntax of the new --filter_cmd option.
709 - new executable: para_play, a tiny alsa player. It
710 can play wave files or raw pcm (16 bit little endian)
711 from stdin.
712 - new executable: para_compress, a dynamic range compressor
713 intended to keep audio output at a consistent volume. Derived
714 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
715 - audiod: New option: --stream_delay. This can be used in
716 a local network to syncronize the audio output of all
717 clients that play the same stream.
718
719
720 ------------------------------------------
721 0.2.2 (2005-08-19) "tangential excitation"
722 ------------------------------------------
723
724 Mostly internal changes in this release, but also some new commands
725 for the mysql database tool.
726
727 - cleanup exec.c, fix para_exec bug
728 - compile time loglevel (log messages below the given level
729 won't be compiled in, which reduces the size of the
730 resulting binaries)
731 - new log macros that shorten the size of the source code.
732 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
733 to send only zeros. With this workaround, para_audioc works
734 again.
735 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
736 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
737 (new entry), "snp" (set numplayed). Read the manual for more
738 information.
739
740
741 ---------------------------------------
742 0.2.1 (2005-08-15) "surreal experience"
743 ---------------------------------------
744
745 Here comes paraslash-0.2.1. It contains a couple of new features and,
746 surprise, only minor bug fixes.
747
748 - kill noisy mp3 debug message
749 - cleanup of the build system
750 - para_server and para_client directly use the crypto routines
751 of the openssl library rather than invoking the openssl command
752 line utitlity
753 - server/audiod: new option --user to switch to the given user
754 when invoked as root. Read the output of "para_server -h" for
755 more information.
756 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
757 status. Default: "para_audioc stat"
758 - sdl_gui: new option --pic_cmd to be used to download the picture.
759 Default: "para_client pic"
760 - audiod: 5 slots ought to be enough for everybody
761 - audiod: new status item: Uptime, kill hup command
762
763
764
765 ------------------------------------------
766 0.2.0 (2005-08-06) "distributed diffusion"
767 ------------------------------------------
768
769 After several month of increased development activity, paraslash-0.2.0
770 has arrived. It contains many new features and is much more
771 self-contained than the old 0.1.x series. Enjoy!
772
773
774 - para_server: fix hang on song change and crash on sighup.
775 Speed up mysql queries. The DIR_LIKE macro is gone.
776 - new executables: para_audiod, the local audio daemon that
777 starts playback (uses SCM_CREDENTIALS socket magic) and
778 para_audioc, the corresponding client.
779 - new executables: para_mp3dec/para_oggdec, two really teensy
780 decoders. para_mp3dec is based on libmad, para_oggdec requires
781 libvorbisfile.
782 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
783 they are now called para_send and para_recv respectively.
784 - documentation updates
785 - para_gui is themable. For now there is the default theme that
786 looks as before and the simple theme: blue and easy.
787 - gui: audio streaming is now handled by audiod. Time display shows
788 playback time rather than streaming time
789 - slider: update to libzmw-0.2.0
790 - para_krell: fix crash on server shutdown
791 - switch from gzip to bzip2
792
793
794 ----------------------------------------
795 0.1.7 (2005-04-18) "melting penetration"
796 ----------------------------------------
797
798 The main change in this release is clearly the oggvorbis rewrite,
799 but there are also lots of smaller changes. If you intend to use both
800 the mp3 and the ogg plugin, it is recommended to use software mixing,
801 e.g. the dmix plugin which is provided by ALSA.
802
803 - new executables: para_ovsend and para_ovrecv for sending/receiving
804 oggvorbis files via rtp. Requires the open rtp library. Get it at
805 http://www.linphone.org/ortp/
806 - rewrite of the ogg_vorbis core code
807 - configure detects libzmw and, if detected, includes
808 para_slider to the list of binaries to be built by make
809 - server stream writers read from their associated fifo rather
810 than from stdin
811 - slider: two new sliders, lastplayed and numplayed
812 - fix nasty double free bug which caused random segfaults in case of
813 mp3 files with invalid header information
814 - gui: new command line option: --stream_timeout=seconds to
815 deactivate a slot if it is idle for that many seconds (default=`5')
816 - diffstats
817
818
819 ---------------------------------------
820 0.1.6 (2005-03-05) "asymptotic balance"
821 ---------------------------------------
822
823 Only little user-visible changes in this release. Mainly bugfixes and
824 core code cleanup. This is probably the most stable version ever if you
825 stick to mp3...
826
827 - fix several memory leaks
828 - rename default name of mysql database from "music" to "paraslash".
829 Use para_server's --mysql_database option if you do not want to
830 rename your old database.
831 - rework ogg vorbis code
832 - make update command work on mysql servers with LOCAL_INFILE
833 disabled
834 - gui: improved stream I/O (slots)
835 - simplified audio format API
836 - para_pob_ogg is gone
837
838 ------------------------------------
839 0.1.5 (2004-12-31) "opaque eternity"
840 ------------------------------------
841
842 Let's slide gently into the new year.
843
844 - new: para_slider (not built automatically, type "make
845 para_slider" to build). A toy for those who always felt that
846 creating stream definitions is difficult. See screenshots,
847 README and FEATURES for more info.
848 - improved signal handling. Fixes server segfault on SIGHUP
849 for linux kernels newer than Aug 24 2004 and makes para_gui
850 race-free.
851 - reload database tool on SIGHUP
852 - improved help message for sl
853 - do not log "broken pipe" messages as errors. They are
854 perfectly ok.
855 - fix wrong error message on permission errors
856
857 -----------------------------------------
858 0.1.4 (2004-12-19) "tunneling transition"
859 -----------------------------------------
860
861 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
862 Hopefully, most of them got wiped out with this release. Some
863 enhancements went also in.
864
865 - improved error diagnostics for all commands
866 - stradd/picadd: overwrite previous contents if entry already
867 exists, rather than returning errors
868 - stradd: use current stream if invoked without args
869 - faster (and hopefully more stable) ogg-vorbis handling
870 - para_krell: reap children to avoid zombie-flooding in case
871 no server is running
872 - si: report also server pid
873 - server: don't busy-loop if dbtool reports only invalid files.
874 - gui: CTRL+C works again, fix stream_read command line option
875 - fix pic_add, hist
876 - fix mysql dbtool startup in case no database exists
877 - many small fixes and cleanups
878
879 ---------------------------------------
880 0.1.3: (2004-12-10) "vanishing inertia"
881 ---------------------------------------
882
883 Starting from this release, the database tools are integrated in the
884 server binary. This decreases server startup time, reduces code size
885 and speeds up database commands. However, the layout of the underlying
886 mysql database changed only slightly and 0.1.3 should be backwards
887 compatible in that respect.
888
889 Visible changes:
890
891 - If mysql is not detected at compile time, or fails to init
892 at runtime, fall back to the dopey database tool which should
893 always work.
894 - para_dbtool and dbtool.conf are gone. All mysql specific
895 options are read from server.conf and are prefixed by 'mysql_'.
896 - new command: cdt (change database tool)
897 - new command line option: dbtool (choose startup database tool)
898 - The name of current stream is now stored in the database,
899 so paraslash remembers its current stream when restarted.
900 - new command: csp (change stream and play)
901 - para_gui also reports current database tool and server uptime
902
903
904 -------------------------------------------
905 0.1.2: (2004-11-28) "spherical fluctuation"
906 -------------------------------------------
907
908 Point release before the big dbtool changes go in.
909
910 - dbtool: rename ca to cam (copy all meta data). It now also
911 copies numplayed and lastplayed time as well as the picture
912 id.
913 - fix endless-loop-bug caused by mp3 files with invalid header
914
915 -----------------------------------------
916 0.1.1: (2004-11-05) "floating atmosphere"
917 -----------------------------------------
918
919 - gkrellm plugin
920 - new dbtool command: mbox. Browse your sound-file collection
921 with your favorite mail reader.
922 - several small fixes
923
924 -------------------------------------
925 0.1.0: (2204-10-22) "rotating cortex"
926 -------------------------------------
927
928 - fix logging bug for loglevel > VERBOSE
929 - fix skip command
930 - correct timings for vbr mp3s
931 - modular audio format support
932 - ogg-vorbis support (experimental)
933 - new server option: autoplay
934
935 -----------------------------------------
936 0.0.99: (2004-07-25) "harmonic deviation"
937 -----------------------------------------
938
939 - rename projectname from icc to paraslash (play, archive, rate
940 and stream large audio sets happily)
941 - paraslash is no longer restricted to one particular audio
942 streaming software
943 - new dbtool commands (stradd, strq, strdel) for easy stream
944 managment w/o configuration file. That obsoletes stream_defs
945 file/config option for dbtool.
946 - picadd accepts jpeg data from stdin
947 - new server commands: ps (select previous stream), sc (song change)
948 - new default pictures for sdl_gui
949 - gui: new key_map option for binding commands and internal
950 functions to arbitrary keys, nice help screen, rip out
951 soundcard/linux specific stuff, avoid noise artefacts while jumping,
952 show silly logo on startup
953 - new executables: para_fade for fading volume, para_dbadm for
954 manipulating attributes
955 - cdb adds _all_ tables to mysql database
956 - revised and beautified documentation
957 - sample dbtool rewritten in C
958 - autoconf
959
960 ---------------------------------------------
961 0.0.98: (2003-12-26) "incremental smoothness"
962 ---------------------------------------------
963
964 - kick icecast in favour of poc. That removes some races and reduces
965 core code considerably.
966 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
967 give finer info on afs' status.
968 - gui can start decoder (see config options). Further new gui
969 commands: refresh (^L), jmp (F1-F10)
970 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
971 terminates gui. This fixes dead instances consuming memory
972 continuously.
973 - new dbtool command: verb for sending verbatim sql queries.
974 - fix pid_list races (by removing pid_list)
975 - codename funnies
976
977 --------------------
978 0.0.97: (2003-10-26)
979 --------------------
980
981 - installation prefix now defaults to /usr/local
982 - new commands for gui: snozze, sleep and reread config
983 - config file for gui and sdl_gui
984 - fix problems with filenames containing funny characters
985 (reported by Thomas Forell)
986 - improved signal handling for gui, now it rereads conf on SIGHUP
987 - new dbtool command: cdb (create database)
988 - switch from argtable to gengetopt
989 - major code cleanup and speed improvements
990 - fix several potential buffer overflows
991 - many small fixes and cleanups
992
993 -------------------
994 0.0.96 (2003-08-30)
995 -------------------
996
997 - easy stream_defs syntax
998 - sdl_gui can display images associated to the file being played
999 - Major feature enhancements for icc_gui including dynamic text
1000 placement and the top/bottom window design
1001 - vrfy/clean now also checks for NULL values in attributes as
1002 well as for invalid picture pointers
1003 - fix long outstanding case sensitivity bug
1004 - many small fixes and cleanups
1005
1006 -------------------
1007 0.0.95 (2003-06-29)
1008 -------------------
1009
1010 - sdl gui runs much faster
1011 - new dbtool command: ca (copy attributes)
1012 - count and display number of times the song has been played
1013 - new feature: scoring
1014 - command line options for sdl_gui
1015 - simpler syntax of streams file
1016 - decrease network traffic of stat
1017 - fix zombie bug
1018 - many small fixes and cleanups
1019
1020 -------------------
1021 0.0.94 (2003-05-04)
1022 -------------------
1023
1024 - new server command: ns (next stream)
1025 - new icc_gui command: c (change stream)
1026 - internal mp3info
1027 - stat shows also id3 tag info
1028 - new sdl based gui
1029 - log flodding bug fixed
1030 - many small fixes and cleanups
1031
1032 -------------------
1033 0.0.93 (2003-03-28)
1034 -------------------
1035
1036 - colors for icc_gui
1037 - icc_gui sets volume directly (linux only)
1038 - proper locking that fixes some races
1039 - fix security bug that caused commands to be executed even
1040 with unsufficient permissions
1041 - new command: hup to make all servers reread their configuration file
1042 - icecast meta data streaming
1043 - many small fixes and cleanups
