paraslash 0.4.13
[paraslash.git] / NEWS
1 --------------------------------------
2 0.4.13 (2013-07-29) "spectral gravity"
3 --------------------------------------
4
5 One more 0.4.x release before the API-breaking changes for 0.5.0 go
6 in. The main features of this release are the ogg/opus audio format,
7 and UTF-8 support, but it includes also tons of other improvements
8 and fixes all over the place.
9
10 - New audio format: ogg/opus.
11 - UTF8 support for para_gui and the mp3 audio format handler.
12 - Scheduler improvements and fixes.
13 - The obsolete gettimeofday() function has been replaced
14 by clock_gettime() on systems which support it.
15 - Speed and usability improvements for para_gui.
16 - para_client now restores the fd flags of stdin and stdout
17 on shutdown.
18 - Improved manual pages.
19 - Consistent version strings for all executables.
20 - Reduced depencies on generated files result in fewer
21 recompilations on changes.
22 - Performance improvements for the compress filter.
23 - Improved downloads web page.
24
25 -----------------------------------------
26 0.4.12 (2012-12-20) "volatile relativity"
27 -----------------------------------------
28 The new command line player, the resample filter, ALSA support for
29 para_fade, and the improved build system are the highlights of this
30 release which probably marks the end of the 0.4.x series.
31
32 - The afh receiver and the para_play executable.
33 - The resample filter: A sample rate converter based on
34 libsamplerate.
35 - The "versions" directory has been removed from the master
36 branch. The tarballs of the old releases are now available
37 in the new "releases" branch.
38 - Overhaul of the build system: All generated files are now
39 written to the "build" directory.
40 - The modular mixer API and the alsa mixer.
41 - Minor fixes for the osx writer.
42
43 --------------------------------------
44 0.4.11 (2012-07-20) "mutual diversity"
45 --------------------------------------
46
47 The major feature in this release is the new sideband API for
48 client-server communication. This API will be used exclusively starting
49 with 0.5.0, which breaks backward compatibility but allows to get rid
50 of quite some compatibility code. Other noteworthy changes include
51 decoder latency improvements and a long-standing bug fix for the
52 ALSA writer.
53
54 - Sideband connections: If both para_server and para_client
55 support this feature, data is sent as a multiplexed stream.
56 - The --no_default_filters option of para_filter has been
57 removed.
58 - Several fixes and latency improvements to various decoders.
59 - The ALSA writer now limits the prebuffer time to 500ms.
60 - Documentation improvements.
61 - Overhaul of the command_util.sh script.
62 - Fixes for some minor problems found by the clang analyzer.
63 - Compiles (almost) without warnings on gcc-3.
64 - Robustness improvements of the buffer tree code.
65
66 ------------------------------------------
67 0.4.10 (2012-03-30) "heterogeneous vacuum"
68 ------------------------------------------
69
70 Nothing earth-shaking in this release, but quite a few usability
71 improvements and the usual mix of cleanups and fixes.
72
73 - The --no_default_filters option of para_filter has been
74 deprecated. It still works but has no effect and will be
75 removed in the next version.
76 - para_gui now prints also the stderr output of the executing
77 command in the bottom window.
78 - Cleanup and consolidation of the various wrappers for
79 write(), writev(), send() and friends.
80 - The obscure error messages on mmap() failures have been
81 replaced by meaningful messages. This affects mainly
82 para_afh.
83 - para_audioc: Cleanups and memory leak fixes.
84 - Test 0004-server no longer fails if para_server is not
85 being built.
86 - New configure options: --with-id3tag-{headers,libs}.
87
88 -------------------------------------
89 0.4.9 (2011-12-06) "hybrid causality"
90 -------------------------------------
91
92 Support for another audio format, interactive mode for para_client
93 and para_audiod and many small improvements/fixes all over the place.
94
95 - Support for flac, the free lossless audio codec.
96 - Fix for an endless loop in the mp3 decoder for certain
97 (corrupt) mp3 files.
98 - When executed without specifying a command, para_client
99 and para_audioc start an interactive shell (requires
100 libreadline being installed). The interactive mode offers
101 full tab completion and command line history.
102 - autogen.sh now detects a distcc setup and adjusts the
103 parameter for the -j option of make accordingly.
104 - Shared memory areas are no longer restricted to 64K. We now
105 detect the maximal size of a shared memory area at runtime.
106 - cleanup of the internal uptime API.
107 - para_server prefaults the mmapped audio file to avoid
108 delays on slow media.
109 - A new test for the test-suite that exercises the
110 communication between para_server and para_audiod.
111 - The alsa writer eats up less CPU cycles when configured to
112 use the DMIX plugin.
113 - Simplified and unified receiver code.
114 - Makefile cleanups.
115 - Commands which print a list of matching audio files now
116 emit a meaningful error message if no audio file matched the
117 given pattern(s).
118
119 --------------------------------------
120 0.4.8 (2011-08-19) "nested assignment"
121 --------------------------------------
122
123 Gcrypt support, the overhauled osx writer and regex format specifiers
124 are the highlights of this release.
125
126 - support for libgcrypt as a drop-in replacement for openssl.
127 Run configure --enable-cryptolib=gcrypt to link against
128 libgcrypt. The two crypto implementations are compatible to
129 each other, i.e. a para_client executable linked against
130 gcrypt can connect to para_server linked against libssl
131 and vice versa.
132 - Rewrite of the osx writer (output plugin for Mac OS).
133 - audiod: The format specifier for receivers, filters and
134 writers is now treated as a regular expression. This allows
135 to replace 5 lines in the config file (one for each audio
136 format) by one single line. See the manual for details.
137 - The *.cmdline.[ch] files are no longer contained in the released
138 tarballs. This reduces the size of the tarballs but requires
139 gengetopt to build the tarball.
140 - Compiles cleanly also with llvm/clang.
141 - Corrupt mp3 files are handled more gracefully.
142 - The alsa writer uses poll fds instead of computing timeouts.
143 - Cleanup of the generic writer API.
144 - sched: Optimized zero timeouts.
145 - vss timeout cleanups.
146 - oggdec fixes and improvements.
147
148 --------------------------------------
149 0.4.7 (2011-06-01) "infinite rollback"
150 --------------------------------------
151
152 The new ao writer, support for ssh RSA keys and a couple of other
153 enhancements.
154
155 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
156 platforms through the libao audio library.
157 - Support for RSA keys generated with ssh-keygen.
158 - configure: improved options for ogg/vorbis/speex.
159 - The git version reported by --version always matches HEAD.
160 - The autogen script detects the number of processors and
161 runs a parallel make if possible.
162 - Major cleanup of the crypto API.
163 - Documentation updates.
164
165 ------------------------------------------
166 0.4.6 (2011-03-31) "deterministic entropy"
167 ------------------------------------------
168
169 Lots of ogg/vorbis improvements, the new test suite, enhancements
170 for para_gui and a fair amount of other bug fixes.
171
172 - For DCCP/OGG streams the audio file header is only sent once
173 at the beginning of the stream rather than periodically
174 every five seconds. This reduces network traffic and the
175 FEC group size.
176 - The vorbis comment header is replaced by an empty dummy header
177 before the header is sent over the network. This also results in
178 less network traffic and smaller FEC groups.
179 - The new "test" make target allows to perform some sanity checks prior
180 to installing the package.
181 - ogg timing fixes and performance improvements
182 - Scheduler improvements
183 - Proper exit codes for para_write
184 - para_gui: New option --theme to select a startup theme. Several
185 other improvements and fixes.
186 - aacdec error message cleanups
187 - simplified color error handling
188
189 --------------------------------------------
190 0.4.5 (2010-12-17) "symmetric randomization"
191 --------------------------------------------
192
193 Bug fixes, internal cleanups and variable-sized FEC slices.
194
195 - Contains a fix for an invalid-free-bug in the ogg audio format
196 handler code.
197 - Switching off the DCCP sender works again.
198 - para_audiod handles crashes of para_server more robustly.
199 - Internal scheduler and writer cleanups.
200 - Reduced latency due to variable-sized FEC slices.
201 - Improved documentation and error diagnostics.
202 - The build of para_server is now optional, allowing the build
203 to succeed in case libosl is not installed.
204
205 ------------------------------------------
206 0.4.4 (2010-08-06) "persistent regularity"
207 ------------------------------------------
208
209 Support for yet another audio format, para_write improvements and
210 bug fixes.
211
212 - Support for the speex codec.
213 - Support for sample formats other than 16 bit little endian.
214 - error2.h is now created by a perl script which speeds up configure
215 considerably.
216 - Fix a bug in the aac decoder which could lead to segfaults in
217 para_filter/para_audiod.
218 - Fixes for autoconf-2.66.
219
220 ----------------------------------------
221 0.4.3 (2010-07-05) "imaginary radiation"
222 ----------------------------------------
223
224 Many improvements for the DCCP and the UDP transport, the new user
225 manual and the usual mix of bug fixes and internal improvements.
226
227 - FEC support for the DCCP sender (Gerrit Renker). The new
228 --dccp_max_slice_size, --dccp_data_slices_per_group and
229 --dccp_slices_per_group options can be used to set the FEC
230 parameters for the DCCP transport.
231 - DNS lookups for UDP targets (Gerrit Renker).
232 - The new user manual replaces the README, README.afs, REQUIREMENTS
233 and INSTALL documents.
234 - Fix an end-of-file detection bug in the oggdec filter.
235 - The new nonblock API.
236 - Both options of the oggdec filter have been removed.
237 - New debug mode for the internal scheduler.
238
239 ------------------------------------------
240 0.4.2 (2010-04-23) "associative expansion"
241 ------------------------------------------
242
243 It's been some time since the last release, but finally here is
244 paraslash-0.4.2. The bulk of the changes comes from the new buffer
245 tree API, but there are changes all over the tree. Mainly performance
246 and usability improvements, but also quite some bug fixes.
247
248 - The new buffer tree API.
249 - DCCP: Support for CCID negotiation (Gerrit Renker).
250 - UDP robustness fixes.
251 - The --bufsize option for mp3dec is gone as it no longer makes sense
252 for the new buffer tree API.
253 - Fix audible buffer underruns for wma streams.
254 - The alsa writer no longer prints meaningless underrun durations.
255 - audiod: Defaults work also for udp streams. If no filter is
256 given for an audio format that is received via upd, fecdec is
257 automatically added as the first filter (along with the decoder).
258
259 ---------------------------------------
260 0.4.1 (2009-12-22) "concurrent horizon"
261 ---------------------------------------
262
263 Support for another audio format, minor feature enhancements and lots of bug
264 fixes. All fixes that have been accumulated in the maint branch (in particular
265 those mentionened in the 0.3.6 release notes) appear in this release as well.
266
267 - wma support.
268 - new afh option: --human to activate human-readable output.
269 - new server/audiod option: --log-timing to print timing information.
270 - build system improvements.
271 - source code documentation updates.
272
273 -------------------------------------
274 0.3.6 (2009-12-07) "cubic continuity"
275 -------------------------------------
276
277 Quite a few bugs have been found and fixed since 0.3.5, so here's
278 another 0.3.x release. No new features.
279
280 - Always check return value of malloc().
281 - ogg vorbis/FEC: Do not write garbage after the audio file header.
282 - exit if root privileges could not be dropped.
283 - FEC: Fix computation of extra slices.
284 - oss: Fix check for empty input buffer.
285 - Avoid buffer underruns due to filter chain output buffer constraints.
286 - server: Fix assignment of afs_pid.
287 - Don't panic if the afs database contains unknown audio formats.
288 - http/dccp: Do not send the audio file header twice.
289 - FEC: Timing improvements.
290
291 ----------------------------------------------
292 0.4.0 (2009-11-10) "simultaneous independence"
293 ----------------------------------------------
294
295 Two significant changes which require the new version number: The
296 improved authentication dialog and the fact that the database code
297 has been moved to a library, libosl. To use the new version, you have
298 to generate new RSA keys, see INSTALL for details. A shell script is
299 provided for conversion of the 0.3 database to the new 0.4 format.
300
301 - stronger crypto for client authentication
302 - the database code has been moved to a library
303 - improved status item handling
304 - cleanup of the build system
305 - The "-V" option now also prints the git version
306 - the new parser-friendly listing mode for the ls and stat commands
307 - mandatory rc4 encryption
308 - major audio format handler cleanups
309 - (id3,...) tags are no longer stored as a combined string in the database
310 - new mood methods: artist_matches, title_matches, comment_matches,
311 album_matches, year_maches, year.
312
313 --------------------------------------------
314 0.3.5 (2009-09-21) "symplectic separability"
315 --------------------------------------------
316
317 Full client support for *BSD Unixes, complete re-write of the ogg
318 vorbis audio format handler, various improvements all over the place
319 and the usual mix of bugfixes. This release marks the end of the 0.3
320 series if no serious problems show up.
321
322 - the new oss writer (supported on *BSD and Linux)
323 - rewrite of the ogg vorbis audio format handler. It's
324 recommended to replace the chunk tables of existing ogg
325 vorbis files in the afs database by re-adding these files
326 with "add -f".
327 - support for netmask subsets (Gerrit Renker)
328 - the new prebuffer filter
329 - improved signal handling
330 - variable fec output buffer size
331 - improved FEC timing fixes audible buffer underruns in UDP mode
332 - --log_color actually works
333 - new ls option: -d (print dates as seconds after the epoch)
334 - update to gengetopt 2.22.2
335 - support for RSA keys of size > 512 bits
336 - new option "mixer_channel" for para_fade
337
338 -----------------------------------------
339 0.3.4 (2009-05-07) "elliptic inheritance"
340 -----------------------------------------
341
342 The new udp sender, forward error correction, colored logs and various
343 other improvements. As the udp sender does not depend on any special
344 libraries, it is built unconditionally.
345
346 - The udp sender replaces the ortp sender. The new code uses forward
347 error correction to protect against packet losses. Many thanks to
348 Gerrit Renker for providing ipv6 support.
349 - The default port for udp streaming now defaults to 8000, like
350 for the http and the dccp senders/receivers.
351 - Loglevels are now specified as symbolic names, e.g.
352 "--loglevel info".
353 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
354 - para_server/para_audiod: Color support for log messages.
355 - new options for mp3dec: --ignore-crc, --bufsize
356 - new audiod option: --config-file.
357 - gengetopt cleanups.
358 - Improved help/man pages: The documentation of para_audiod,
359 para_recv, para_filter and para_write now also contains
360 all options of the available receivers/filters/writers. The
361 man page of para_fade contains a description of the different
362 modes of operation.
363 - More source code documentation.
364 - vss timing fixes.
365
366 --------------------------------------------
367 0.3.3 (2008-12-01) "axiomatic perspectivity"
368 --------------------------------------------
369
370 Internal code cleanups, bug fixes, improved tag handling and the new
371 amplification filter.
372
373 - para_server uses the generic scheduling code.
374 - overhaul of the virtual streaming system.
375 - mp3: id3 version 2 support via libid3tag (optional)
376 - ogg: vorbis comment support.
377 - aac meta info support.
378 - mp3 audio format handler cleanups.
379 - new filter: "amp" to amplify the amplitude of the audio stream
380 - new status item/database entry: amplification. It is
381 used by the amp filter to pre-amplify the audio stream.
382 - fix a close-without-open bug in para_write.
383 - fix a bug in com_init() which was introduced in 0.3.2.
384 - better error diagnostics for para_client.
385
386 -----------------------------------------
387 0.3.2 (2008-04-11) "probabilistic parity"
388 -----------------------------------------
389
390 The new para_afh executable, scheduling and documentation improvements.
391
392 - new ls option: -lc (list chunk table)
393 - new executable: para_afh, the stand-alone audio file handler tool
394 - afs commands can send output more than SHMMAX (32MB on Linux). This
395 also reduces the memory usage of commands that produce large amounts
396 of output.
397 - major scheduler and audiod cleanups.
398 - more detailed and much nicer man pages.
399
400 ---------------------------------------
401 0.3.1 (2008-02-23) "liquid interaction"
402 ---------------------------------------
403
404 A mix of cleanups, bug fixes, improvements, and some new features. No
405 significant changes to the new database (osl) code, which is generally
406 a good sign.
407
408 - Share some similar/duplicate code between the http and the
409 dccp sender.
410 - Generic access control lists for paraslash senders.
411 - dccp sender: Access control lists, connection limiting and support
412 for the allow,deny,on,off,help sender commands.
413 - The default dccp port changed from 5001 to 8000 (suggested by
414 Gerrit Renker).
415 - para_server starts even if not all public keys could be loaded.
416 - Audiod performance improvements.
417 - fix a bug in the "off" command of the http sender.
418 - fix some fd and memory leaks.
419 - Update to gengetopt-2.22.
420
421 -------------------------------------
422 0.3.0 (2008-01-12) "solar saturation"
423 -------------------------------------
424
425 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
426
427
428 Usually one might expect lots of new features AND a big increase in size
429 for a major release like this.
430
431 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
432 ever. The decrease in size is mostly due to the removal of some
433 graphical tools (which were only quick hacks anyway). But also the
434 fact that the mysql code is gone cuts down the size a bit.
435
436 Being independent of mysql comes at a cost: The fact that paraslash
437 now contains its own database (the object storage layer, osl) increases
438 the (stripped) binary size of para_server by ~50K on i386.
439
440 - no more restrictions on unique basenames.
441 - independent of mysql: The new self-contained object
442 storage layer (osl) replaces the mysql database.
443 - New executable para_fsck: Check integrity of osl tables.
444 - Lyrics support.
445 - Reliable audio file move/rename detection.
446 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
447 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
448 Solaris (sparc64).
449 - the new osl-based audio file selector (afs) replaces the random,
450 the playlist and the mysql selector of paraslash-0.2.x.
451 - IPv6 support (thanks to Gerrit Renker).
452 - paraslash-0.2.x streams are now called "moods". Writing
453 0.3.x-mood definitions should be both easier and more
454 powerful than writing 0.2.x-stream definitions.
455 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
456 been removed. The world is a better place without them. However,
457 para_gui is still there.
458 - afs tracks audio file selection also in playlist mode.
459 - few easy-to-use afs commands replace the many not-so-easy-to-use
460 mysql commands (and are available also in playlist mode).
461 - Improved error subsystem.
462 - The earth-shaking new logo.
463
464 -----------------------------------------
465 0.2.17 (2007-11-20) "isotropic threshold"
466 -----------------------------------------
467
468 Mainly bugfixes and cleanups in this version which marks the end of
469 the 0.2.x series if no serious bugs show up after the release.
470
471 - mysql_selector: fix a locking bug.
472 - universal chunk queueing.
473 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
474 to Gerrit Renker).
475 - be more carful wrt. signed vs. unsigned argument passing.
476 - cleanup error.h and fix some references to invalid error
477 codes.
478 - update to gengetopt-2.21.
479 - update to ortp-0.13.1.
480 - autoconf: extend checks for headers, library functions and
481 compiler characteristics.
482 - Fix streaming of large mp3 files.
483 - Fix an off-by-one bug in playlist handling.
484
485 --------------------------------------
486 0.2.16 (2007-04-05) "neural discharge"
487 --------------------------------------
488
489 The main change in this release is the major audio format handler
490 cleanup which removes some similar/duplicate code and makes it easier
491 to implement plugins for other audio formats. Of course, the usual mix
492 of other improvements/changes/bugfixes also made it into the release.
493
494 - simplified audio format handlers (most of the handling functions
495 were moved one layer up to the virtual streaming system).
496 - para_server uses mmap to read audio files
497 - repositioning of mp3 streams is much faster, in particular for
498 jumping near the end of large mp3 files.
499 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
500 and AFS_WRITE.
501 - fix a bug in para_filter that caused decoding of aac files
502 to start only after a few seconds.
503 - fix osx_writer hangs
504 - simplified dccp code (thanks to Gerrit Renker)
505 - the compress filter works also on big endian systems (ppc)
506
507 -----------------------------------------
508 0.2.15 (2007-02-16) "inductive resonance"
509 -----------------------------------------
510
511 Minor improvements, more documentation and a bunch of bug fixes.
512
513 - para_server: The server.users file is only read once on server
514 startup rather than for each connection
515 - mp3dec: Fix decoding of corrupt mp3 files
516 - afs (audio file sender) is now called vss (virtual streaming
517 system). Consequently, the permission flags specified in
518 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
519 become VSS_READ and VSS_WRITE respectively.
520 - para_audiod/para_filter: Fix a bug that caused the last chunk
521 of audio data not being written under certain circumstances
522 - audiod: compute the difference of server time and local time
523 correctly
524 - para_server/para_audiod: Fix some memory leaks
525 - documentation improvements
526 - configure.ac: fix checks for para_krell
527 - new man pages
528
529 -------------------------------------------
530 0.2.14 (2006-10-15) "transient singularity"
531 -------------------------------------------
532
533 The only major enhancement of this version is the osx writer which completes
534 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
535 until now for reasons beyond the scope of this changelog entry.
536
537 - new output plugin for Mac Os: the osx writer
538 - rename configure command line options from --enable-xxx-headers to
539 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
540 - configure: new command line options: --with-mad-headers,
541 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
542 - some robustness fixes
543 - dymamic audio format recognition for audiod
544 - para_server: new command line option: --autoplay_delay
545 - para_audiod: new command line option: --clock_diff_count
546
547 ---------------------------------------
548 0.2.13 (2006-07-14) "sonic convolution"
549 ---------------------------------------
550
551 A bunch of new features and core changes.
552
553 - the new paraslash scheduler, short and sweet.
554 - Support for m4a/mp4 files via the new aac audio format
555 handler/filter (requires libfaad).
556 - each writer has its own command line parser, just like
557 para_recv and para_filter.
558 - para_client and para_audioc use the error subsystem
559 - writers are integrated in para_audiod (currently linux-only)
560 - para_client is integrated in para_audiod
561 - random/playlist selector: improved info strings
562 - new audiod commands: tasks, kill
563 - update to libortp-0.10.1
564 - para_fade: wake time defaults to 8 hours from now
565 - update to autoconf-2.60
566
567 ------------------------------------------
568 0.2.12 (2006-05-12) "oriented abstraction"
569 ------------------------------------------
570
571 Many user-visible changes in this release and lots of new
572 features:
573
574
575 - the new optional dccp sender/receiver. It uses the datagram
576 congestion control protocol. You'll need a fairly new kernel
577 for this.
578 - paraslash works on Mac OS X (thanks to Gerd Becker)
579 - para_play renamed to para_write
580 - modular output plugin design (writers) for para_write
581 - new file_writer output plugin for para_write
582 - compress filter speed improvements
583 - update to libortp-0.9.1
584 - update to gengetopt-2.17rc
585 - para_client no longer depends on libreadline (as the
586 code for the interactive mode was removed).
587 - gcc-2-95 is no longer a supported compiler. It may still
588 work, but it gets no more testing.
589 - the tarball no longer contains the screenshot images which
590 reduces its size quite a bit.
591 - configure: new command line options: --enable-mysql-headers
592 and --enable-mysql-libs
593
594 ------------------------------------
595 0.2.11 (2006-03-11) "atomic duality"
596 ------------------------------------
597
598 Here it is, the first paraslash release developed with git. There
599 are fairly many user-visible changes in this release. As two out of
600 the three "database tools" of paraslash don't use a database at all,
601 they are now called "audio file selectors" instead.
602
603
604 - the cdt command (change database tool) becomes chs (change
605 selector)
606 - no more colon separators: The syntax of some options of
607 para_audiod and para_filter have changed. Use --help for
608 more info (and some examples).
609 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
610 - switch from cvs to git (should've done that earlier)
611 - the new ipc subsystem
612 - new audio file selector: playlist
613 - para_server: the dopey selector is now called "random",
614 and is the default selector. Use the --selector option to
615 choose another selector at startup, or the chs command to
616 change the selector at runtime.
617 - X86_64 fixes (thanks to Steffen Klassert)
618 - para_play fixes
619
620 --------------------------------------
621 0.2.10 (2006-02-17) "cyclic attractor"
622 --------------------------------------
623
624 Huge documentation update, a scrollable window for para_gui, ortp
625 improvements, and of course many small fixes not mentioned here.
626 The diffstat below is rather misleading as most insertions are due
627 to the new source documentation.
628
629 - autoconf cleanup
630 - para_server also uses the new error subsystem
631 - lots of new documentation (UTSL)
632 - gui improvements:
633 - keysyms for cursor keys and for next/previous page keys
634 - scrollable output window
635 - new internal commands: scroll up/down, page up/down
636 - fix color of command output.
637 - ortp: the --chunk_time and --header flags are no longer needed
638 for para_recv/para_audiod as this information is now encoded in
639 each rtp packet sent by para_server.
640
641 -------------------------------------------
642 0.2.9 (2006-01-24) "progressive turbulence"
643 -------------------------------------------
644
645 Internal audiod receivers/filters, the new error subsystem and
646 a lot of small improvements.
647
648 - para_recv and para_filter are integrated into the para_audiod
649 binary, i.e. audiod no longer spawns a new process for
650 each receiver/filter. As para_recv and para_filter might be
651 useful as standalone programs, they still get built (linked
652 against the same object files that are also used for audiod).
653 - further ortp timing improvements should reduce the CPU usage
654 of the ortp receiver.
655 - improved audio grabbing. The 'grab' command of para_audiod
656 has its own set of command line options. Read the output of
657 "para_audioc help grab" for more info.
658 - oggdec: configurable input prebuffer size.
659 - the new error subsystem gives better error diagnostics
660 and reduces code size.
661
662 -----------------------------------------
663 0.2.8 (2006-01-02) "dynamic accumulation"
664 -----------------------------------------
665
666 The new modular filter design and the para_play-hangs bugfix.
667
668 - new executable: para_filter. It combines para_mp3dec,
669 para_oggdec and para_compress. It also adds a further filter
670 type, wav, that just inserts a wave header at the desired point
671 of the filter chain. All 'piping' is done in-memory (i.e. no
672 read/write operations are used).
673 - para_play: fix a stupid bug that caused it to hang under
674 certain circumstances.
675
676 -------------------------------------------
677 0.2.7 (2006-12-27) "transparent invariance"
678 -------------------------------------------
679
680 Not many user-visible changes but a fair amount of internal improvements.
681
682
683 - The http sender buffers data if it can not be sent
684 out immediately (because the socket is not writable). This
685 should prevent para_server from shutting down the connection
686 too early on a loaded network.
687 - para_play also prebuffers data if it is told to start at a
688 future time by the --start_time option.
689 - The return of para_recv: It combines para_ortp_recv and
690 para_http_recv. Use the --receiver option to switch between
691 the two. para_recv builds without libortp, but contains
692 only the http receiver in this case.
693 - update to ortp 0.8.1. As this ortp release contains incompatible
694 changes, para_recv-0.2.7 won't link against older ortp libs.
695 - improved ortp timings.
696 - use of gcc-extensions that #define away for non-gcc and
697 gcc < 3.0.
698
699 -------------------------------------------
700 0.2.6 (2005-10-29) "recursive compensation"
701 -------------------------------------------
702
703 Transparent session encryption (uses openssl's Alleged RC4 cipher),
704 the internal find command and several other improvements and cleanups.
705
706 - Encrypt the session if encryption is requested by the client
707 (default for para_client 0.2.6). This is backwards
708 compatible, so older clients can still connect to para_server
709 0.2.6. Use the new client option --plain to request an
710 uncrypted session (off by default, must be set to on in
711 order to connect to para_server 0.2.x with 0 <= x <= 5).
712 - para_server uses an internal function to locate audio files
713 rather than calling find(1). The server option
714 --mysql_audio_file_dir replaces --mysql_find_cmd.
715 - documentation update
716 - man pages
717 - header file cleanup
718 - para_client code cleanup
719 - para_gui: faster display of output of display commands
720
721 ------------------------------------------
722 0.2.5 (2005-10-13) "aggressive resolution"
723 ------------------------------------------
724
725 This release adds internal senders, i.e. no more external programs are
726 spawned for sending out the audio data. There are two different senders
727 available: The http sender and the ortp sender (former para_send which
728 is no longer needed).
729
730 The new sender code has a plugin-like design so it can be easily
731 extended should there be be any future need for supporting another
732 network streaming protocol. All senders are completely independent of
733 each other. In particular, the http and the ortp sender can operate
734 in parallel.
735
736 - new server command: sender to control senders at runtime.
737 Read the output of "para_server -h" and "para_client help
738 sender" for more information.
739 - para_recv renamed to para_ortp_recv
740 - new executable: para_http_recv, a simple command line
741 http receiver.
742 - major afs/mp3/ogg code simplifications due to internal
743 senders.
744 - ogg timing improvements
745 - fix several minor memory leaks (found by valgrind)
746 - empty stream definitions work again
747 - com_ne(): ignore errors on remove
748 - audiod: fix segfault on server restart
749
750 ---------------------------------------
751 0.2.4 (2005-09-21) "toxic anticipation"
752 ---------------------------------------
753
754 Several small improvements, fixes and the new grab command.
755
756 - audiod:
757 - new command: "grab" to grab the output of the stream reader
758 or any filters. Read the output of "para_audioc help grab"
759 for more information.
760 - fix memory leak
761 - code cleanup
762 - audioc: new command line option: --bufsize to specify a
763 buffer size different from the default size 8192.
764 - improved error diagnostics for para_play.
765 - new configure option: --enable-ssldir so search for openssl in
766 non-standard places
767 - sdl_gui: Make it look nice again for 1024x768
768 - server: report total size of memory allocated with sbrk by malloc,
769 new command line option: --announce_time
770
771 -----------------------------------------
772 0.2.3 (2005-09-01) "hydrophilic movement"
773 -----------------------------------------
774
775 Two new executables and major feature enhancements.
776
777 - audiod filters: It is now possible to specify arbitrary many
778 (including none) filters for each supported audio
779 format. This can be used e.g. for normalizing volume,
780 transforming or grabbing the audio stream, or for using
781 visualizers. Read the output of "para_audiod -h" for the
782 syntax of the new --filter_cmd option.
783 - new executable: para_play, a tiny alsa player. It
784 can play wave files or raw pcm (16 bit little endian)
785 from stdin.
786 - new executable: para_compress, a dynamic range compressor
787 intended to keep audio output at a consistent volume. Derived
788 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
789 - audiod: New option: --stream_delay. This can be used in
790 a local network to syncronize the audio output of all
791 clients that play the same stream.
792
793 ------------------------------------------
794 0.2.2 (2005-08-19) "tangential excitation"
795 ------------------------------------------
796
797 Mostly internal changes in this release, but also some new commands
798 for the mysql database tool.
799
800 - cleanup exec.c, fix para_exec bug
801 - compile time loglevel (log messages below the given level
802 won't be compiled in, which reduces the size of the
803 resulting binaries)
804 - new log macros that shorten the size of the source code.
805 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
806 to send only zeros. With this workaround, para_audioc works
807 again.
808 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
809 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
810 (new entry), "snp" (set numplayed). Read the manual for more
811 information.
812
813 ---------------------------------------
814 0.2.1 (2005-08-15) "surreal experience"
815 ---------------------------------------
816
817 Here comes paraslash-0.2.1. It contains a couple of new features and,
818 surprise, only minor bug fixes.
819
820 - kill noisy mp3 debug message
821 - cleanup of the build system
822 - para_server and para_client directly use the crypto routines
823 of the openssl library rather than invoking the openssl command
824 line utitlity
825 - server/audiod: new option --user to switch to the given user
826 when invoked as root. Read the output of "para_server -h" for
827 more information.
828 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
829 status. Default: "para_audioc stat"
830 - sdl_gui: new option --pic_cmd to be used to download the picture.
831 Default: "para_client pic"
832 - audiod: 5 slots ought to be enough for everybody
833 - audiod: new status item: Uptime, kill hup command
834
835 ------------------------------------------
836 0.2.0 (2005-08-06) "distributed diffusion"
837 ------------------------------------------
838
839 After several month of increased development activity, paraslash-0.2.0
840 has arrived. It contains many new features and is much more
841 self-contained than the old 0.1.x series. Enjoy!
842
843
844 - para_server: fix hang on song change and crash on sighup.
845 Speed up mysql queries. The DIR_LIKE macro is gone.
846 - new executables: para_audiod, the local audio daemon that
847 starts playback (uses SCM_CREDENTIALS socket magic) and
848 para_audioc, the corresponding client.
849 - new executables: para_mp3dec/para_oggdec, two really teensy
850 decoders. para_mp3dec is based on libmad, para_oggdec requires
851 libvorbisfile.
852 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
853 they are now called para_send and para_recv respectively.
854 - documentation updates
855 - para_gui is themable. For now there is the default theme that
856 looks as before and the simple theme: blue and easy.
857 - gui: audio streaming is now handled by audiod. Time display shows
858 playback time rather than streaming time
859 - slider: update to libzmw-0.2.0
860 - para_krell: fix crash on server shutdown
861 - switch from gzip to bzip2
862
863 ----------------------------------------
864 0.1.7 (2005-04-18) "melting penetration"
865 ----------------------------------------
866
867 The main change in this release is clearly the oggvorbis rewrite,
868 but there are also lots of smaller changes. If you intend to use both
869 the mp3 and the ogg plugin, it is recommended to use software mixing,
870 e.g. the dmix plugin which is provided by ALSA.
871
872 - new executables: para_ovsend and para_ovrecv for sending/receiving
873 oggvorbis files via rtp. Requires the open rtp library. Get it at
874 http://www.linphone.org/ortp/
875 - rewrite of the ogg_vorbis core code
876 - configure detects libzmw and, if detected, includes
877 para_slider to the list of binaries to be built by make
878 - server stream writers read from their associated fifo rather
879 than from stdin
880 - slider: two new sliders, lastplayed and numplayed
881 - fix nasty double free bug which caused random segfaults in case of
882 mp3 files with invalid header information
883 - gui: new command line option: --stream_timeout=seconds to
884 deactivate a slot if it is idle for that many seconds (default=`5')
885 - diffstats
886
887 ---------------------------------------
888 0.1.6 (2005-03-05) "asymptotic balance"
889 ---------------------------------------
890
891 Only little user-visible changes in this release. Mainly bugfixes and
892 core code cleanup. This is probably the most stable version ever if you
893 stick to mp3...
894
895 - fix several memory leaks
896 - rename default name of mysql database from "music" to "paraslash".
897 Use para_server's --mysql_database option if you do not want to
898 rename your old database.
899 - rework ogg vorbis code
900 - make update command work on mysql servers with LOCAL_INFILE
901 disabled
902 - gui: improved stream I/O (slots)
903 - simplified audio format API
904 - para_pob_ogg is gone
905
906 ------------------------------------
907 0.1.5 (2004-12-31) "opaque eternity"
908 ------------------------------------
909
910 Let's slide gently into the new year.
911
912 - new: para_slider (not built automatically, type "make
913 para_slider" to build). A toy for those who always felt that
914 creating stream definitions is difficult. See screenshots,
915 README and FEATURES for more info.
916 - improved signal handling. Fixes server segfault on SIGHUP
917 for linux kernels newer than Aug 24 2004 and makes para_gui
918 race-free.
919 - reload database tool on SIGHUP
920 - improved help message for sl
921 - do not log "broken pipe" messages as errors. They are
922 perfectly ok.
923 - fix wrong error message on permission errors
924
925 -----------------------------------------
926 0.1.4 (2004-12-19) "tunneling transition"
927 -----------------------------------------
928
929 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
930 Hopefully, most of them got wiped out with this release. Some
931 enhancements went also in.
932
933 - improved error diagnostics for all commands
934 - stradd/picadd: overwrite previous contents if entry already
935 exists, rather than returning errors
936 - stradd: use current stream if invoked without args
937 - faster (and hopefully more stable) ogg-vorbis handling
938 - para_krell: reap children to avoid zombie-flooding in case
939 no server is running
940 - si: report also server pid
941 - server: don't busy-loop if dbtool reports only invalid files.
942 - gui: CTRL+C works again, fix stream_read command line option
943 - fix pic_add, hist
944 - fix mysql dbtool startup in case no database exists
945 - many small fixes and cleanups
946
947 ---------------------------------------
948 0.1.3: (2004-12-10) "vanishing inertia"
949 ---------------------------------------
950
951 Starting from this release, the database tools are integrated in the
952 server binary. This decreases server startup time, reduces code size
953 and speeds up database commands. However, the layout of the underlying
954 mysql database changed only slightly and 0.1.3 should be backwards
955 compatible in that respect.
956
957 Visible changes:
958
959 - If mysql is not detected at compile time, or fails to init
960 at runtime, fall back to the dopey database tool which should
961 always work.
962 - para_dbtool and dbtool.conf are gone. All mysql specific
963 options are read from server.conf and are prefixed by 'mysql_'.
964 - new command: cdt (change database tool)
965 - new command line option: dbtool (choose startup database tool)
966 - The name of current stream is now stored in the database,
967 so paraslash remembers its current stream when restarted.
968 - new command: csp (change stream and play)
969 - para_gui also reports current database tool and server uptime
970
971 -------------------------------------------
972 0.1.2: (2004-11-28) "spherical fluctuation"
973 -------------------------------------------
974
975 Point release before the big dbtool changes go in.
976
977 - dbtool: rename ca to cam (copy all meta data). It now also
978 copies numplayed and lastplayed time as well as the picture
979 id.
980 - fix endless-loop-bug caused by mp3 files with invalid header
981
982 -----------------------------------------
983 0.1.1: (2004-11-05) "floating atmosphere"
984 -----------------------------------------
985
986 - gkrellm plugin
987 - new dbtool command: mbox. Browse your sound-file collection
988 with your favorite mail reader.
989 - several small fixes
990
991 -------------------------------------
992 0.1.0: (2004-10-22) "rotating cortex"
993 -------------------------------------
994
995 - fix logging bug for loglevel > VERBOSE
996 - fix skip command
997 - correct timings for vbr mp3s
998 - modular audio format support
999 - ogg-vorbis support (experimental)
1000 - new server option: autoplay
1001
1002 -----------------------------------------
1003 0.0.99: (2004-07-25) "harmonic deviation"
1004 -----------------------------------------
1005
1006 - rename projectname from icc to paraslash (play, archive, rate
1007 and stream large audio sets happily)
1008 - paraslash is no longer restricted to one particular audio
1009 streaming software
1010 - new dbtool commands (stradd, strq, strdel) for easy stream
1011 managment w/o configuration file. That obsoletes stream_defs
1012 file/config option for dbtool.
1013 - picadd accepts jpeg data from stdin
1014 - new server commands: ps (select previous stream), sc (song change)
1015 - new default pictures for sdl_gui
1016 - gui: new key_map option for binding commands and internal
1017 functions to arbitrary keys, nice help screen, rip out
1018 soundcard/linux specific stuff, avoid noise artefacts while jumping,
1019 show silly logo on startup
1020 - new executables: para_fade for fading volume, para_dbadm for
1021 manipulating attributes
1022 - cdb adds _all_ tables to mysql database
1023 - revised and beautified documentation
1024 - sample dbtool rewritten in C
1025 - autoconf
1026
1027 ---------------------------------------------
1028 0.0.98: (2003-12-26) "incremental smoothness"
1029 ---------------------------------------------
1030
1031 - kick icecast in favour of poc. That removes some races and reduces
1032 core code considerably.
1033 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
1034 give finer info on afs' status.
1035 - gui can start decoder (see config options). Further new gui
1036 commands: refresh (^L), jmp (F1-F10)
1037 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1038 terminates gui. This fixes dead instances consuming memory
1039 continuously.
1040 - new dbtool command: verb for sending verbatim sql queries.
1041 - fix pid_list races (by removing pid_list)
1042 - codename funnies
1043
1044 --------------------
1045 0.0.97: (2003-10-26)
1046 --------------------
1047
1048 - installation prefix now defaults to /usr/local
1049 - new commands for gui: snozze, sleep and reread config
1050 - config file for gui and sdl_gui
1051 - fix problems with filenames containing funny characters
