[paraslash.git] / NEWS
1 -------------------------------------------
2 0.4.11 (to be announced) "mutual diversity"
3 -------------------------------------------
4
5 The major feature in this release is the new sideband API for
6 client-server communication. This API will be used exclusively starting
7 with 0.5.0, which breaks backward compatibility but allows to get rid
8 of quite some compatibility code. Other noteworthy changes include
9 decoder latency improvements and a long-standing bug fix for the
10 ALSA writer.
11
12 - Sideband connections: If both para_server and para_client
13 support this feature, data is sent as a multiplexed stream.
14 - The --no_default_filters option of para_filter has been
15 removed.
16 - Several fixes and latency improvements to various decoders.
17 - The ALSA writer now limits the prebuffer time to 500ms.
18 - Documentation improvements.
19 - Overhaul of the command_util.sh script.
20 - Fixes for some minor problems found by the clang analyzer.
21 - Compiles (almost) without warnings on gcc-3.
22 - Robustness improvements of the buffer tree code.
23
24 ------------------------------------------
25 0.4.10 (2012-03-30) "heterogeneous vacuum"
26 ------------------------------------------
27
28 Nothing earth-shaking in this release, but quite a few usability
29 improvements and the usual mix of cleanups and fixes.
30
31 - The --no_default_filters option of para_filter has been
32 deprecated. It still works but has no effect and will be
33 removed in the next version.
34 - para_gui now prints also the stderr output of the executing
35 command in the bottom window.
36 - Cleanup and consolidation of the various wrappers for
37 write(), writev(), send() and friends.
38 - The obscure error messages on mmap() failures have been
39 replaced by meaningful messages. This affects mainly
40 para_afh.
41 - para_audioc: Cleanups and memory leak fixes.
42 - Test 0004-server no longer fails if para_server is not
43 being built.
44 - New configure options: --with-id3tag-{headers,libs}.
45
46 -------------------------------------
47 0.4.9 (2011-12-06) "hybrid causality"
48 -------------------------------------
49
50 Support for another audio format, interactive mode for para_client
51 and para_audiod and many small improvements/fixes all over the place.
52
53 - Support for flac, the free lossless audio codec.
54 - Fix for an endless loop in the mp3 decoder for certain
55 (corrupt) mp3 files.
56 - When executed without specifying a command, para_client
57 and para_audioc start an interactive shell (requires
58 libreadline being installed). The interactive mode offers
59 full tab completion and command line history.
60 - autogen.sh now detects a distcc setup and adjusts the
61 parameter for the -j option of make accordingly.
62 - Shared memory areas are no longer restricted to 64K. We now
63 detect the maximal size of a shared memory area at runtime.
64 - cleanup of the internal uptime API.
65 - para_server prefaults the mmapped audio file to avoid
66 delays on slow media.
67 - A new test for the test-suite that exercises the
68 communication between para_server and para_audiod.
69 - The alsa writer eats up less CPU cycles when configured to
70 use the DMIX plugin.
71 - Simplified and unified receiver code.
72 - Makefile cleanups.
73 - Commands which print a list of matching audio files now
74 emit a meaningful error message if no audio file matched the
75 given pattern(s).
76
77 --------------------------------------
78 0.4.8 (2011-08-19) "nested assignment"
79 --------------------------------------
80
81 Gcrypt support, the overhauled osx writer and regex format specifiers
82 are the highlights of this release.
83
84 - support for libgcrypt as a drop-in replacement for openssl.
85 Run configure --enable-cryptolib=gcrypt to link against
86 libgcrypt. The two crypto implementations are compatible to
87 each other, i.e. a para_client executable linked against
88 gcrypt can connect to para_server linked against libssl
89 and vice versa.
90 - Rewrite of the osx writer (output plugin for Mac OS).
91 - audiod: The format specifier for receivers, filters and
92 writers is now treated as a regular expression. This allows
93 to replace 5 lines in the config file (one for each audio
94 format) by one single line. See the manual for details.
95 - The *.cmdline.[ch] files are no longer contained in the released
96 tarballs. This reduces the size of the tarballs but requires
97 gengetopt to build the tarball.
98 - Compiles cleanly also with llvm/clang.
99 - Corrupt mp3 files are handled more gracefully.
100 - The alsa writer uses poll fds instead of computing timeouts.
101 - Cleanup of the generic writer API.
102 - sched: Optimized zero timeouts.
103 - vss timeout cleanups.
104 - oggdec fixes and improvements.
105
106 --------------------------------------
107 0.4.7 (2011-06-01) "infinite rollback"
108 --------------------------------------
109
110 The new ao writer, support for ssh RSA keys and a couple of other
111 enhancements.
112
113 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
114 platforms through the libao audio library.
115 - Support for RSA keys generated with ssh-keygen.
116 - configure: improved options for ogg/vorbis/speex.
117 - The git version reported by --version always matches HEAD.
118 - The autogen script detects the number of processors and
119 runs a parallel make if possible.
120 - Major cleanup of the crypto API.
121 - Documentation updates.
122
123 ------------------------------------------
124 0.4.6 (2011-03-31) "deterministic entropy"
125 ------------------------------------------
126
127 Lots of ogg/vorbis improvements, the new test suite, enhancements
128 for para_gui and a fair amount of other bug fixes.
129
130 - For DCCP/OGG streams the audio file header is only sent once
131 at the beginning of the stream rather than periodically
132 every five seconds. This reduces network traffic and the
133 FEC group size.
134 - The vorbis comment header is replaced by an empty dummy header
135 before the header is sent over the network. This also results in
136 less network traffic and smaller FEC groups.
137 - The new "test" make target allows to perform some sanity checks prior
138 to installing the package.
139 - ogg timing fixes and performance improvements
140 - Scheduler improvements
141 - Proper exit codes for para_write
142 - para_gui: New option --theme to select a startup theme. Several
143 other improvements and fixes.
144 - aacdec error message cleanups
145 - simplified color error handling
146
147 --------------------------------------------
148 0.4.5 (2010-12-17) "symmetric randomization"
149 --------------------------------------------
150
151 Bug fixes, internal cleanups and variable-sized FEC slices.
152
153 - Contains a fix for an invalid-free-bug in the ogg audio format
154 handler code.
155 - Switching off the DCCP sender works again.
156 - para_audiod handles crashes of para_server more robustly.
157 - Internal scheduler and writer cleanups.
158 - Reduced latency due to variable-sized FEC slices.
159 - Improved documentation and error diagnostics.
160 - The build of para_server is now optional, allowing the build
161 to succeed in case libosl is not installed.
162
163 ------------------------------------------
164 0.4.4 (2010-08-06) "persistent regularity"
165 ------------------------------------------
166
167 Support for yet another audio format, para_write improvements and
168 bug fixes.
169
170 - Support for the speex codec.
171 - Support for sample formats other than 16 bit little endian.
172 - error2.h is now created by a perl script which speeds up configure
173 considerably.
174 - Fix a bug in the aac decoder which could lead to segfaults in
175 para_filter/para_audiod.
176 - Fixes for autoconf-2.66.
177
178 ----------------------------------------
179 0.4.3 (2010-07-05) "imaginary radiation"
180 ----------------------------------------
181
182 Many improvements for the DCCP and the UDP transport, the new user
183 manual and the usual mix of bug fixes and internal improvements.
184
185 - FEC support for the DCCP sender (Gerrit Renker). The new
186 --dccp_max_slice_size, --dccp_data_slices_per_group and
187 --dccp_slices_per_group options can be used to set the FEC
188 parameters for the DCCP transport.
189 - DNS lookups for UDP targets (Gerrit Renker).
190 - The new user manual replaces the README, README.afs, REQUIREMENTS
191 and INSTALL documents.
192 - Fix an end-of-file detection bug in the oggdec filter.
193 - The new nonblock API.
194 - Both options of the oggdec filter have been removed.
195 - New debug mode for the internal scheduler.
196
197 ------------------------------------------
198 0.4.2 (2010-04-23) "associative expansion"
199 ------------------------------------------
200
201 It's been some time since the last release, but finally here is
202 paraslash-0.4.2. The bulk of the changes comes from the new buffer
203 tree API, but there are changes all over the tree. Mainly performance
204 and usability improvements, but also quite some bug fixes.
205
206 - The new buffer tree API.
207 - DCCP: Support for CCID negotiation (Gerrit Renker).
208 - UDP robustness fixes.
209 - The --bufsize option for mp3dec is gone as it no longer makes sense
210 for the new buffer tree API.
211 - Fix audible buffer underruns for wma streams.
212 - The alsa writer no longer prints meaningless underrun durations.
213 - audiod: Defaults work also for udp streams. If no filter is
214 given for an audio format that is received via upd, fecdec is
215 automatically added as the first filter (along with the decoder).
216
217 ---------------------------------------
218 0.4.1 (2009-12-22) "concurrent horizon"
219 ---------------------------------------
220
221 Support for another audio format, minor feature enhancements and lots of bug
222 fixes. All fixes that have been accumulated in the maint branch (in particular
223 those mentionened in the 0.3.6 release notes) appear in this release as well.
224
225 - wma support.
226 - new afh option: --human to activate human-readable output.
227 - new server/audiod option: --log-timing to print timing information.
228 - build system improvements.
229 - source code documentation updates.
230
231 -------------------------------------
232 0.3.6 (2009-12-07) "cubic continuity"
233 -------------------------------------
234
235 Quite a few bugs have been found and fixed since 0.3.5, so here's
236 another 0.3.x release. No new features.
237
238 - Always check return value of malloc().
239 - ogg vorbis/FEC: Do not write garbage after the audio file header.
240 - exit if root privileges could not be dropped.
241 - FEC: Fix computation of extra slices.
242 - oss: Fix check for empty input buffer.
243 - Avoid buffer underruns due to filter chain output buffer constraints.
244 - server: Fix assignment of afs_pid.
245 - Don't panic if the afs database contains unknown audio formats.
246 - http/dccp: Do not send the audio file header twice.
247 - FEC: Timing improvements.
248
249 ----------------------------------------------
250 0.4.0 (2009-11-10) "simultaneous independence"
251 ----------------------------------------------
252
253 Two significant changes which require the new version number: The
254 improved authentication dialog and the fact that the database code
255 has been moved to a library, libosl. To use the new version, you have
256 to generate new RSA keys, see INSTALL for details. A shell script is
257 provided for conversion of the 0.3 database to the new 0.4 format.
258
259 - stronger crypto for client authentication
260 - the database code has been moved to a library
261 - improved status item handling
262 - cleanup of the build system
263 - The "-V" option now also prints the git version
264 - the new parser-friendly listing mode for the ls and stat commands
265 - mandatory rc4 encryption
266 - major audio format handler cleanups
267 - (id3,...) tags are no longer stored as a combined string in the database
268 - new mood methods: artist_matches, title_matches, comment_matches,
269 album_matches, year_maches, year.
270
271 --------------------------------------------
272 0.3.5 (2009-09-21) "symplectic separability"
273 --------------------------------------------
274
275 Full client support for *BSD Unixes, complete re-write of the ogg
276 vorbis audio format handler, various improvements all over the place
277 and the usual mix of bugfixes. This release marks the end of the 0.3
278 series if no serious problems show up.
279
280 - the new oss writer (supported on *BSD and Linux)
281 - rewrite of the ogg vorbis audio format handler. It's
282 recommended to replace the chunk tables of existing ogg
283 vorbis files in the afs database by re-adding these files
284 with "add -f".
285 - support for netmask subsets (Gerrit Renker)
286 - the new prebuffer filter
287 - improved signal handling
288 - variable fec output buffer size
289 - improved FEC timing fixes audible buffer underruns in UDP mode
290 - --log_color actually works
291 - new ls option: -d (print dates as seconds after the epoch)
292 - update to gengetopt 2.22.2
293 - support for RSA keys of size > 512 bits
294 - new option "mixer_channel" for para_fade
295
296 -----------------------------------------
297 0.3.4 (2009-05-07) "elliptic inheritance"
298 -----------------------------------------
299
300 The new udp sender, forward error correction, colored logs and various
301 other improvements. As the udp sender does not depend on any special
302 libraries, it is built unconditionally.
303
304 - The udp sender replaces the ortp sender. The new code uses forward
305 error correction to protect against packet losses. Many thanks to
306 Gerrit Renker for providing ipv6 support.
307 - The default port for udp streaming now defaults to 8000, like
308 for the http and the dccp senders/receivers.
309 - Loglevels are now specified as symbolic names, e.g.
310 "--loglevel info".
311 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
312 - para_server/para_audiod: Color support for log messages.
313 - new options for mp3dec: --ignore-crc, --bufsize
314 - new audiod option: --config-file.
315 - gengetopt cleanups.
316 - Improved help/man pages: The documentation of para_audiod,
317 para_recv, para_filter and para_write now also contains
318 all options of the available receivers/filters/writers. The
319 man page of para_fade contains a description of the different
320 modes of operation.
321 - More source code documentation.
322 - vss timing fixes.
323
324 --------------------------------------------
325 0.3.3 (2008-12-01) "axiomatic perspectivity"
326 --------------------------------------------
327
328 Internal code cleanups, bug fixes, improved tag handling and the new
329 amplification filter.
330
331 - para_server uses the generic scheduling code.
332 - overhaul of the virtual streaming system.
333 - mp3: id3 version 2 support via libid3tag (optional)
334 - ogg: vorbis comment support.
335 - aac meta info support.
336 - mp3 audio format handler cleanups.
337 - new filter: "amp" to amplify the amplitude of the audio stream
338 - new status item/database entry: amplification. It is
339 used by the amp filter to pre-amplify the audio stream.
340 - fix a close-without-open bug in para_write.
341 - fix a bug in com_init() which was introduced in 0.3.2.
342 - better error diagnostics for para_client.
343
344 -----------------------------------------
345 0.3.2 (2008-04-11) "probabilistic parity"
346 -----------------------------------------
347
348 The new para_afh executable, scheduling and documentation improvements.
349
350 - new ls option: -lc (list chunk table)
351 - new executable: para_afh, the stand-alone audio file handler tool
352 - afs commands can send output more than SHMMAX (32MB on Linux). This
353 also reduces the memory usage of commands that produce large amounts
354 of output.
355 - major scheduler and audiod cleanups.
356 - more detailed and much nicer man pages.
357
358 ---------------------------------------
359 0.3.1 (2008-02-23) "liquid interaction"
360 ---------------------------------------
361
362 A mix of cleanups, bug fixes, improvements, and some new features. No
363 significant changes to the new database (osl) code, which is generally
364 a good sign.
365
366 - Share some similar/duplicate code between the http and the
367 dccp sender.
368 - Generic access control lists for paraslash senders.
369 - dccp sender: Access control lists, connection limiting and support
370 for the allow,deny,on,off,help sender commands.
371 - The default dccp port changed from 5001 to 8000 (suggested by
372 Gerrit Renker).
373 - para_server starts even if not all public keys could be loaded.
374 - Audiod performance improvements.
375 - fix a bug in the "off" command of the http sender.
376 - fix some fd and memory leaks.
377 - Update to gengetopt-2.22.
378
379 -------------------------------------
380 0.3.0 (2008-01-12) "solar saturation"
381 -------------------------------------
382
383 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
384
385
386 Usually one might expect lots of new features AND a big increase in size
387 for a major release like this.
388
389 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
390 ever. The decrease in size is mostly due to the removal of some
391 graphical tools (which were only quick hacks anyway). But also the
392 fact that the mysql code is gone cuts down the size a bit.
393
394 Being independent of mysql comes at a cost: The fact that paraslash
395 now contains its own database (the object storage layer, osl) increases
396 the (stripped) binary size of para_server by ~50K on i386.
397
398 - no more restrictions on unique basenames.
399 - independent of mysql: The new self-contained object
400 storage layer (osl) replaces the mysql database.
401 - New executable para_fsck: Check integrity of osl tables.
402 - Lyrics support.
403 - Reliable audio file move/rename detection.
404 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
405 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
406 Solaris (sparc64).
407 - the new osl-based audio file selector (afs) replaces the random,
408 the playlist and the mysql selector of paraslash-0.2.x.
409 - IPv6 support (thanks to Gerrit Renker).
410 - paraslash-0.2.x streams are now called "moods". Writing
411 0.3.x-mood definitions should be both easier and more
412 powerful than writing 0.2.x-stream definitions.
413 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
414 been removed. The world is a better place without them. However,
415 para_gui is still there.
416 - afs tracks audio file selection also in playlist mode.
417 - few easy-to-use afs commands replace the many not-so-easy-to-use
418 mysql commands (and are available also in playlist mode).
419 - Improved error subsystem.
420 - The earth-shaking new logo.
421
422 -----------------------------------------
423 0.2.17 (2007-11-20) "isotropic threshold"
424 -----------------------------------------
425
426 Mainly bugfixes and cleanups in this version which marks the end of
427 the 0.2.x series if no serious bugs show up after the release.
428
429 - mysql_selector: fix a locking bug.
430 - universal chunk queueing.
431 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
432 to Gerrit Renker).
433 - be more carful wrt. signed vs. unsigned argument passing.
434 - cleanup error.h and fix some references to invalid error
435 codes.
436 - update to gengetopt-2.21.
437 - update to ortp-0.13.1.
438 - autoconf: extend checks for headers, library functions and
439 compiler characteristics.
440 - Fix streaming of large mp3 files.
441 - Fix an off-by-one bug in playlist handling.
442
443 --------------------------------------
444 0.2.16 (2007-04-05) "neural discharge"
445 --------------------------------------
446
447 The main change in this release is the major audio format handler
448 cleanup which removes some similar/duplicate code and makes it easier
449 to implement plugins for other audio formats. Of course, the usual mix
450 of other improvements/changes/bugfixes also made it into the release.
451
452 - simplified audio format handlers (most of the handling functions
453 were moved one layer up to the virtual streaming system).
454 - para_server uses mmap to read audio files
455 - repositioning of mp3 streams is much faster, in particular for
456 jumping near the end of large mp3 files.
457 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
458 and AFS_WRITE.
459 - fix a bug in para_filter that caused decoding of aac files
460 to start only after a few seconds.
461 - fix osx_writer hangs
462 - simplified dccp code (thanks to Gerrit Renker)
463 - the compress filter works also on big endian systems (ppc)
464
465 -----------------------------------------
466 0.2.15 (2007-02-16) "inductive resonance"
467 -----------------------------------------
468
469 Minor improvements, more documentation and a bunch of bug fixes.
470
471 - para_server: The server.users file is only read once on server
472 startup rather than for each connection
473 - mp3dec: Fix decoding of corrupt mp3 files
474 - afs (audio file sender) is now called vss (virtual streaming
475 system). Consequently, the permission flags specified in
476 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
477 become VSS_READ and VSS_WRITE respectively.
478 - para_audiod/para_filter: Fix a bug that caused the last chunk
479 of audio data not being written under certain circumstances
480 - audiod: compute the difference of server time and local time
481 correctly
482 - para_server/para_audiod: Fix some memory leaks
483 - documentation improvements
484 - configure.ac: fix checks for para_krell
485 - new man pages
486
487 -------------------------------------------
488 0.2.14 (2006-10-15) "transient singularity"
489 -------------------------------------------
490
491 The only major enhancement of this version is the osx writer which completes
492 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
493 until now for reasons beyond the scope of this changelog entry.
494
495 - new output plugin for Mac Os: the osx writer
496 - rename configure command line options from --enable-xxx-headers to
497 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
498 - configure: new command line options: --with-mad-headers,
499 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
500 - some robustness fixes
501 - dymamic audio format recognition for audiod
502 - para_server: new command line option: --autoplay_delay
503 - para_audiod: new command line option: --clock_diff_count
504
505 ---------------------------------------
506 0.2.13 (2006-07-14) "sonic convolution"
507 ---------------------------------------
508
509 A bunch of new features and core changes.
510
511 - the new paraslash scheduler, short and sweet.
512 - Support for m4a/mp4 files via the new aac audio format
513 handler/filter (requires libfaad).
514 - each writer has its own command line parser, just like
515 para_recv and para_filter.
516 - para_client and para_audioc use the error subsystem
517 - writers are integrated in para_audiod (currently linux-only)
518 - para_client is integrated in para_audiod
519 - random/playlist selector: improved info strings
520 - new audiod commands: tasks, kill
521 - update to libortp-0.10.1
522 - para_fade: wake time defaults to 8 hours from now
523 - update to autoconf-2.60
524
525
526 ------------------------------------------
527 0.2.12 (2006-05-12) "oriented abstraction"
528 ------------------------------------------
529
530 Many user-visible changes in this release and lots of new
531 features:
532
533
534 - the new optional dccp sender/receiver. It uses the datagram
535 congestion control protocol. You'll need a fairly new kernel
536 for this.
537 - paraslash works on Mac OS X (thanks to Gerd Becker)
538 - para_play renamed to para_write
539 - modular output plugin design (writers) for para_write
540 - new file_writer output plugin for para_write
541 - compress filter speed improvements
542 - update to libortp-0.9.1
543 - update to gengetopt-2.17rc
544 - para_client no longer depends on libreadline (as the
545 code for the interactive mode was removed).
546 - gcc-2-95 is no longer a supported compiler. It may still
547 work, but it gets no more testing.
548 - the tarball no longer contains the screenshot images which
549 reduces its size quite a bit.
550 - configure: new command line options: --enable-mysql-headers
551 and --enable-mysql-libs
552
553 ------------------------------------
554 0.2.11 (2006-03-11) "atomic duality"
555 ------------------------------------
556
557 Here it is, the first paraslash release developed with git. There
558 are fairly many user-visible changes in this release. As two out of
559 the three "database tools" of paraslash don't use a database at all,
560 they are now called "audio file selectors" instead.
561
562
563 - the cdt command (change database tool) becomes chs (change
564 selector)
565 - no more colon separators: The syntax of some options of
566 para_audiod and para_filter have changed. Use --help for
567 more info (and some examples).
568 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
569 - switch from cvs to git (should've done that earlier)
570 - the new ipc subsystem
571 - new audio file selector: playlist
572 - para_server: the dopey selector is now called "random",
573 and is the default selector. Use the --selector option to
574 choose another selector at startup, or the chs command to
575 change the selector at runtime.
576 - X86_64 fixes (thanks to Steffen Klassert)
577 - para_play fixes
578
579
580 --------------------------------------
581 0.2.10 (2006-02-17) "cyclic attractor"
582 --------------------------------------
583
584 Huge documentation update, a scrollable window for para_gui, ortp
585 improvements, and of course many small fixes not mentioned here.
586 The diffstat below is rather misleading as most insertions are due
587 to the new source documentation.
588
589 - autoconf cleanup
590 - para_server also uses the new error subsystem
591 - lots of new documentation (UTSL)
592 - gui improvements:
593 - keysyms for cursor keys and for next/previous page keys
594 - scrollable output window
595 - new internal commands: scroll up/down, page up/down
596 - fix color of command output.
597 - ortp: the --chunk_time and --header flags are no longer needed
598 for para_recv/para_audiod as this information is now encoded in
599 each rtp packet sent by para_server.
600
601
602 -------------------------------------------
603 0.2.9 (2006-01-24) "progressive turbulence"
604 -------------------------------------------
605
606 Internal audiod receivers/filters, the new error subsystem and
607 a lot of small improvements.
608
609 - para_recv and para_filter are integrated into the para_audiod
610 binary, i.e. audiod no longer spawns a new process for
611 each receiver/filter. As para_recv and para_filter might be
612 useful as standalone programs, they still get built (linked
613 against the same object files that are also used for audiod).
614 - further ortp timing improvements should reduce the CPU usage
615 of the ortp receiver.
616 - improved audio grabbing. The 'grab' command of para_audiod
617 has its own set of command line options. Read the output of
618 "para_audioc help grab" for more info.
619 - oggdec: configurable input prebuffer size.
620 - the new error subsystem gives better error diagnostics
621 and reduces code size.
622
623
624 -----------------------------------------
625 0.2.8 (2006-01-02) "dynamic accumulation"
626 -----------------------------------------
627
628 The new modular filter design and the para_play-hangs bugfix.
629
630 - new executable: para_filter. It combines para_mp3dec,
631 para_oggdec and para_compress. It also adds a further filter
632 type, wav, that just inserts a wave header at the desired point
633 of the filter chain. All 'piping' is done in-memory (i.e. no
634 read/write operations are used).
635 - para_play: fix a stupid bug that caused it to hang under
636 certain circumstances.
637
638
639 -------------------------------------------
640 0.2.7 (2006-12-27) "transparent invariance"
641 -------------------------------------------
642
643 Not many user-visible changes but a fair amount of internal improvements.
644
645
646 - The http sender buffers data if it can not be sent
647 out immediately (because the socket is not writable). This
648 should prevent para_server from shutting down the connection
649 too early on a loaded network.
650 - para_play also prebuffers data if it is told to start at a
651 future time by the --start_time option.
652 - The return of para_recv: It combines para_ortp_recv and
653 para_http_recv. Use the --receiver option to switch between
654 the two. para_recv builds without libortp, but contains
655 only the http receiver in this case.
656 - update to ortp 0.8.1. As this ortp release contains incompatible
657 changes, para_recv-0.2.7 won't link against older ortp libs.
658 - improved ortp timings.
659 - use of gcc-extensions that #define away for non-gcc and
660 gcc < 3.0.
661
662
663 -------------------------------------------
664 0.2.6 (2005-10-29) "recursive compensation"
665 -------------------------------------------
666
667 Transparent session encryption (uses openssl's Alleged RC4 cipher),
668 the internal find command and several other improvements and cleanups.
669
670 - Encrypt the session if encryption is requested by the client
671 (default for para_client 0.2.6). This is backwards
672 compatible, so older clients can still connect to para_server
673 0.2.6. Use the new client option --plain to request an
674 uncrypted session (off by default, must be set to on in
675 order to connect to para_server 0.2.x with 0 <= x <= 5).
676 - para_server uses an internal function to locate audio files
677 rather than calling find(1). The server option
678 --mysql_audio_file_dir replaces --mysql_find_cmd.
679 - documentation update
680 - man pages
681 - header file cleanup
682 - para_client code cleanup
683 - para_gui: faster display of output of display commands
684
685
686 ------------------------------------------
687 0.2.5 (2005-10-13) "aggressive resolution"
688 ------------------------------------------
689
690 This release adds internal senders, i.e. no more external programs are
691 spawned for sending out the audio data. There are two different senders
692 available: The http sender and the ortp sender (former para_send which
693 is no longer needed).
694
695 The new sender code has a plugin-like design so it can be easily
696 extended should there be be any future need for supporting another
697 network streaming protocol. All senders are completely independent of
698 each other. In particular, the http and the ortp sender can operate
699 in parallel.
700
701 - new server command: sender to control senders at runtime.
702 Read the output of "para_server -h" and "para_client help
703 sender" for more information.
704 - para_recv renamed to para_ortp_recv
705 - new executable: para_http_recv, a simple command line
706 http receiver.
707 - major afs/mp3/ogg code simplifications due to internal
708 senders.
709 - ogg timing improvements
710 - fix several minor memory leaks (found by valgrind)
711 - empty stream definitions work again
712 - com_ne(): ignore errors on remove
713 - audiod: fix segfault on server restart
714
715
716 ---------------------------------------
717 0.2.4 (2005-09-21) "toxic anticipation"
718 ---------------------------------------
719
720 Several small improvements, fixes and the new grab command.
721
722 - audiod:
723 - new command: "grab" to grab the output of the stream reader
724 or any filters. Read the output of "para_audioc help grab"
725 for more information.
726 - fix memory leak
727 - code cleanup
728 - audioc: new command line option: --bufsize to specify a
729 buffer size different from the default size 8192.
730 - improved error diagnostics for para_play.
731 - new configure option: --enable-ssldir so search for openssl in
732 non-standard places
733 - sdl_gui: Make it look nice again for 1024x768
734 - server: report total size of memory allocated with sbrk by malloc,
735 new command line option: --announce_time
736
737
738 -----------------------------------------
739 0.2.3 (2005-09-01) "hydrophilic movement"
740 -----------------------------------------
741
742 Two new executables and major feature enhancements.
743
744 - audiod filters: It is now possible to specify arbitrary many
745 (including none) filters for each supported audio
746 format. This can be used e.g. for normalizing volume,
747 transforming or grabbing the audio stream, or for using
748 visualizers. Read the output of "para_audiod -h" for the
749 syntax of the new --filter_cmd option.
750 - new executable: para_play, a tiny alsa player. It
751 can play wave files or raw pcm (16 bit little endian)
752 from stdin.
753 - new executable: para_compress, a dynamic range compressor
754 intended to keep audio output at a consistent volume. Derived
755 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
756 - audiod: New option: --stream_delay. This can be used in
757 a local network to syncronize the audio output of all
758 clients that play the same stream.
759
760
761 ------------------------------------------
762 0.2.2 (2005-08-19) "tangential excitation"
763 ------------------------------------------
764
765 Mostly internal changes in this release, but also some new commands
766 for the mysql database tool.
767
768 - cleanup exec.c, fix para_exec bug
769 - compile time loglevel (log messages below the given level
770 won't be compiled in, which reduces the size of the
771 resulting binaries)
772 - new log macros that shorten the size of the source code.
773 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
774 to send only zeros. With this workaround, para_audioc works
775 again.
776 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
777 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
778 (new entry), "snp" (set numplayed). Read the manual for more
779 information.
780
781
782 ---------------------------------------
783 0.2.1 (2005-08-15) "surreal experience"
784 ---------------------------------------
785
786 Here comes paraslash-0.2.1. It contains a couple of new features and,
787 surprise, only minor bug fixes.
788
789 - kill noisy mp3 debug message
790 - cleanup of the build system
791 - para_server and para_client directly use the crypto routines
792 of the openssl library rather than invoking the openssl command
793 line utitlity
794 - server/audiod: new option --user to switch to the given user
795 when invoked as root. Read the output of "para_server -h" for
796 more information.
797 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
798 status. Default: "para_audioc stat"
799 - sdl_gui: new option --pic_cmd to be used to download the picture.
800 Default: "para_client pic"
801 - audiod: 5 slots ought to be enough for everybody
802 - audiod: new status item: Uptime, kill hup command
803
804
805
806 ------------------------------------------
807 0.2.0 (2005-08-06) "distributed diffusion"
808 ------------------------------------------
809
810 After several month of increased development activity, paraslash-0.2.0
811 has arrived. It contains many new features and is much more
812 self-contained than the old 0.1.x series. Enjoy!
813
814
815 - para_server: fix hang on song change and crash on sighup.
816 Speed up mysql queries. The DIR_LIKE macro is gone.
817 - new executables: para_audiod, the local audio daemon that
818 starts playback (uses SCM_CREDENTIALS socket magic) and
819 para_audioc, the corresponding client.
820 - new executables: para_mp3dec/para_oggdec, two really teensy
821 decoders. para_mp3dec is based on libmad, para_oggdec requires
822 libvorbisfile.
823 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
824 they are now called para_send and para_recv respectively.
825 - documentation updates
826 - para_gui is themable. For now there is the default theme that
827 looks as before and the simple theme: blue and easy.
828 - gui: audio streaming is now handled by audiod. Time display shows
829 playback time rather than streaming time
830 - slider: update to libzmw-0.2.0
831 - para_krell: fix crash on server shutdown
832 - switch from gzip to bzip2
833
834
835 ----------------------------------------
836 0.1.7 (2005-04-18) "melting penetration"
837 ----------------------------------------
838
839 The main change in this release is clearly the oggvorbis rewrite,
840 but there are also lots of smaller changes. If you intend to use both
841 the mp3 and the ogg plugin, it is recommended to use software mixing,
842 e.g. the dmix plugin which is provided by ALSA.
843
844 - new executables: para_ovsend and para_ovrecv for sending/receiving
845 oggvorbis files via rtp. Requires the open rtp library. Get it at
846 http://www.linphone.org/ortp/
847 - rewrite of the ogg_vorbis core code
848 - configure detects libzmw and, if detected, includes
849 para_slider to the list of binaries to be built by make
850 - server stream writers read from their associated fifo rather
851 than from stdin
852 - slider: two new sliders, lastplayed and numplayed
853 - fix nasty double free bug which caused random segfaults in case of
854 mp3 files with invalid header information
855 - gui: new command line option: --stream_timeout=seconds to
856 deactivate a slot if it is idle for that many seconds (default=`5')
857 - diffstats
858
859
860 ---------------------------------------
861 0.1.6 (2005-03-05) "asymptotic balance"
862 ---------------------------------------
863
864 Only little user-visible changes in this release. Mainly bugfixes and
865 core code cleanup. This is probably the most stable version ever if you
866 stick to mp3...
867
868 - fix several memory leaks
869 - rename default name of mysql database from "music" to "paraslash".
870 Use para_server's --mysql_database option if you do not want to
871 rename your old database.
872 - rework ogg vorbis code
873 - make update command work on mysql servers with LOCAL_INFILE
874 disabled
875 - gui: improved stream I/O (slots)
876 - simplified audio format API
877 - para_pob_ogg is gone
878
879 ------------------------------------
880 0.1.5 (2004-12-31) "opaque eternity"
881 ------------------------------------
882
883 Let's slide gently into the new year.
884
885 - new: para_slider (not built automatically, type "make
886 para_slider" to build). A toy for those who always felt that
887 creating stream definitions is difficult. See screenshots,
888 README and FEATURES for more info.
889 - improved signal handling. Fixes server segfault on SIGHUP
890 for linux kernels newer than Aug 24 2004 and makes para_gui
891 race-free.
892 - reload database tool on SIGHUP
893 - improved help message for sl
894 - do not log "broken pipe" messages as errors. They are
895 perfectly ok.
896 - fix wrong error message on permission errors
897
898 -----------------------------------------
899 0.1.4 (2004-12-19) "tunneling transition"
900 -----------------------------------------
901
902 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
903 Hopefully, most of them got wiped out with this release. Some
904 enhancements went also in.
905
906 - improved error diagnostics for all commands
907 - stradd/picadd: overwrite previous contents if entry already
908 exists, rather than returning errors
909 - stradd: use current stream if invoked without args
910 - faster (and hopefully more stable) ogg-vorbis handling
911 - para_krell: reap children to avoid zombie-flooding in case
912 no server is running
913 - si: report also server pid
914 - server: don't busy-loop if dbtool reports only invalid files.
915 - gui: CTRL+C works again, fix stream_read command line option
916 - fix pic_add, hist
917 - fix mysql dbtool startup in case no database exists
918 - many small fixes and cleanups
919
920 ---------------------------------------
921 0.1.3: (2004-12-10) "vanishing inertia"
922 ---------------------------------------
923
924 Starting from this release, the database tools are integrated in the
925 server binary. This decreases server startup time, reduces code size
926 and speeds up database commands. However, the layout of the underlying
927 mysql database changed only slightly and 0.1.3 should be backwards
928 compatible in that respect.
929
930 Visible changes:
931
932 - If mysql is not detected at compile time, or fails to init
933 at runtime, fall back to the dopey database tool which should
934 always work.
935 - para_dbtool and dbtool.conf are gone. All mysql specific
936 options are read from server.conf and are prefixed by 'mysql_'.
937 - new command: cdt (change database tool)
938 - new command line option: dbtool (choose startup database tool)
939 - The name of current stream is now stored in the database,
940 so paraslash remembers its current stream when restarted.
941 - new command: csp (change stream and play)
942 - para_gui also reports current database tool and server uptime
943
944
945 -------------------------------------------
946 0.1.2: (2004-11-28) "spherical fluctuation"
947 -------------------------------------------
948
949 Point release before the big dbtool changes go in.
950
951 - dbtool: rename ca to cam (copy all meta data). It now also
952 copies numplayed and lastplayed time as well as the picture
953 id.
954 - fix endless-loop-bug caused by mp3 files with invalid header
955
956 -----------------------------------------
957 0.1.1: (2004-11-05) "floating atmosphere"
958 -----------------------------------------
959
960 - gkrellm plugin
961 - new dbtool command: mbox. Browse your sound-file collection
962 with your favorite mail reader.
963 - several small fixes
964
965 -------------------------------------
966 0.1.0: (2204-10-22) "rotating cortex"
967 -------------------------------------
968
969 - fix logging bug for loglevel > VERBOSE
970 - fix skip command
971 - correct timings for vbr mp3s
972 - modular audio format support
973 - ogg-vorbis support (experimental)
974 - new server option: autoplay
975
976 -----------------------------------------
977 0.0.99: (2004-07-25) "harmonic deviation"
978 -----------------------------------------
979
980 - rename projectname from icc to paraslash (play, archive, rate
981 and stream large audio sets happily)
982 - paraslash is no longer restricted to one particular audio
983 streaming software
984 - new dbtool commands (stradd, strq, strdel) for easy stream
985 managment w/o configuration file. That obsoletes stream_defs
986 file/config option for dbtool.
987 - picadd accepts jpeg data from stdin
988 - new server commands: ps (select previous stream), sc (song change)
989 - new default pictures for sdl_gui
990 - gui: new key_map option for binding commands and internal
991 functions to arbitrary keys, nice help screen, rip out
992 soundcard/linux specific stuff, avoid noise artefacts while jumping,
993 show silly logo on startup
994 - new executables: para_fade for fading volume, para_dbadm for
995 manipulating attributes
996 - cdb adds _all_ tables to mysql database
997 - revised and beautified documentation
998 - sample dbtool rewritten in C
999 - autoconf
1000
1001 ---------------------------------------------
1002 0.0.98: (2003-12-26) "incremental smoothness"
1003 ---------------------------------------------
1004
1005 - kick icecast in favour of poc. That removes some races and reduces
1006 core code considerably.
1007 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1008 give finer info on afs' status.
1009 - gui can start decoder (see config options). Further new gui
1010 commands: refresh (^L), jmp (F1-F10)
1011 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1012 terminates gui. This fixes dead instances consuming memory
1013 continuously.
1014 - new dbtool command: verb for sending verbatim sql queries.
1015 - fix pid_list races (by removing pid_list)
1016 - codename funnies
1017
1018 --------------------
1019 0.0.97: (2003-10-26)
1020 --------------------
1021
1022 - installation prefix now defaults to /usr/local
1023 - new commands for gui: snozze, sleep and reread config
1024 - config file for gui and sdl_gui
1025 - fix problems with filenames containing funny characters
1026 (reported by Thomas Forell)
1027 - improved signal handling for gui, now it rereads conf on SIGHUP
1028 - new dbtool command: cdb (create database)
1029 - switch from argtable to gengetopt
1030 - major code cleanup and speed improvements
1031 - fix several potential buffer overflows
1032 - many small fixes and cleanups
1033
1034 -------------------
1035 0.0.96 (2003-08-30)
1036 -------------------
1037
1038 - easy stream_defs syntax
1039 - sdl_gui can display images associated to the file being played
1040 - Major feature enhancements for icc_gui including dynamic text
1041 placement and the top/bottom window design
1042 - vrfy/clean now also checks for NULL values in attributes as
1043 well as for invalid picture pointers
1044 - fix long outstanding case sensitivity bug
1045 - many small fixes and cleanups
1046
1047 -------------------
1048 0.0.95 (2003-06-29)
1049 -------------------
1050
1051 - sdl gui runs much faster
1052 - new dbtool command: ca (copy attributes)
1053 - count and display number of times the song has been played
1054 - new feature: scoring
1055 - command line options for sdl_gui
1056 - simpler syntax of streams file
1057 - decrease network traffic of stat
1058 - fix zombie bug
1059 - many small fixes and cleanups
1060
1061 -------------------
1062 0.0.94 (2003-05-04)
1063 -------------------
1064
1065 - new server command: ns (next stream)
