Merge branch 't/remove_no_default_filters'
[paraslash.git] / NEWS
1 -------------------------------------------
2 0.4.11 (to be announced) "mutual diversity"
3 -------------------------------------------
4
5 - The --no_default_filters option of para_filter has been
6 removed.
7 - Documentation improvements.
8
9 ------------------------------------------
10 0.4.10 (2012-03-30) "heterogeneous vacuum"
11 ------------------------------------------
12
13 Nothing earth-shaking in this release, but quite a few usability
14 improvements and the usual mix of cleanups and fixes.
15
16 - The --no_default_filters option of para_filter has been
17 deprecated. It still works but has no effect and will be
18 removed in the next version.
19 - para_gui now prints also the stderr output of the executing
20 command in the bottom window.
21 - Cleanup and consolidation of the various wrappers for
22 write(), writev(), send() and friends.
23 - The obscure error messages on mmap() failures have been
24 replaced by meaningful messages. This affects mainly
25 para_afh.
26 - para_audioc: Cleanups and memory leak fixes.
27 - Test 0004-server no longer fails if para_server is not
28 being built.
29 - New configure options: --with-id3tag-{headers,libs}.
30
31 -------------------------------------
32 0.4.9 (2011-12-06) "hybrid causality"
33 -------------------------------------
34
35 Support for another audio format, interactive mode for para_client
36 and para_audiod and many small improvements/fixes all over the place.
37
38 - Support for flac, the free lossless audio codec.
39 - Fix for an endless loop in the mp3 decoder for certain
40 (corrupt) mp3 files.
41 - When executed without specifying a command, para_client
42 and para_audioc start an interactive shell (requires
43 libreadline being installed). The interactive mode offers
44 full tab completion and command line history.
45 - autogen.sh now detects a distcc setup and adjusts the
46 parameter for the -j option of make accordingly.
47 - Shared memory areas are no longer restricted to 64K. We now
48 detect the maximal size of a shared memory area at runtime.
49 - cleanup of the internal uptime API.
50 - para_server prefaults the mmapped audio file to avoid
51 delays on slow media.
52 - A new test for the test-suite that exercises the
53 communication between para_server and para_audiod.
54 - The alsa writer eats up less CPU cycles when configured to
55 use the DMIX plugin.
56 - Simplified and unified receiver code.
57 - Makefile cleanups.
58 - Commands which print a list of matching audio files now
59 emit a meaningful error message if no audio file matched the
60 given pattern(s).
61
62 --------------------------------------
63 0.4.8 (2011-08-19) "nested assignment"
64 --------------------------------------
65
66 Gcrypt support, the overhauled osx writer and regex format specifiers
67 are the highlights of this release.
68
69 - support for libgcrypt as a drop-in replacement for openssl.
70 Run configure --enable-cryptolib=gcrypt to link against
71 libgcrypt. The two crypto implementations are compatible to
72 each other, i.e. a para_client executable linked against
73 gcrypt can connect to para_server linked against libssl
74 and vice versa.
75 - Rewrite of the osx writer (output plugin for Mac OS).
76 - audiod: The format specifier for receivers, filters and
77 writers is now treated as a regular expression. This allows
78 to replace 5 lines in the config file (one for each audio
79 format) by one single line. See the manual for details.
80 - The *.cmdline.[ch] files are no longer contained in the released
81 tarballs. This reduces the size of the tarballs but requires
82 gengetopt to build the tarball.
83 - Compiles cleanly also with llvm/clang.
84 - Corrupt mp3 files are handled more gracefully.
85 - The alsa writer uses poll fds instead of computing timeouts.
86 - Cleanup of the generic writer API.
87 - sched: Optimized zero timeouts.
88 - vss timeout cleanups.
89 - oggdec fixes and improvements.
90
91 --------------------------------------
92 0.4.7 (2011-06-01) "infinite rollback"
93 --------------------------------------
94
95 The new ao writer, support for ssh RSA keys and a couple of other
96 enhancements.
97
98 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
99 platforms through the libao audio library.
100 - Support for RSA keys generated with ssh-keygen.
101 - configure: improved options for ogg/vorbis/speex.
102 - The git version reported by --version always matches HEAD.
103 - The autogen script detects the number of processors and
104 runs a parallel make if possible.
105 - Major cleanup of the crypto API.
106 - Documentation updates.
107
108 ------------------------------------------
109 0.4.6 (2011-03-31) "deterministic entropy"
110 ------------------------------------------
111
112 Lots of ogg/vorbis improvements, the new test suite, enhancements
113 for para_gui and a fair amount of other bug fixes.
114
115 - For DCCP/OGG streams the audio file header is only sent once
116 at the beginning of the stream rather than periodically
117 every five seconds. This reduces network traffic and the
118 FEC group size.
119 - The vorbis comment header is replaced by an empty dummy header
120 before the header is sent over the network. This also results in
121 less network traffic and smaller FEC groups.
122 - The new "test" make target allows to perform some sanity checks prior
123 to installing the package.
124 - ogg timing fixes and performance improvements
125 - Scheduler improvements
126 - Proper exit codes for para_write
127 - para_gui: New option --theme to select a startup theme. Several
128 other improvements and fixes.
129 - aacdec error message cleanups
130 - simplified color error handling
131
132 --------------------------------------------
133 0.4.5 (2010-12-17) "symmetric randomization"
134 --------------------------------------------
135
136 Bug fixes, internal cleanups and variable-sized FEC slices.
137
138 - Contains a fix for an invalid-free-bug in the ogg audio format
139 handler code.
140 - Switching off the DCCP sender works again.
141 - para_audiod handles crashes of para_server more robustly.
142 - Internal scheduler and writer cleanups.
143 - Reduced latency due to variable-sized FEC slices.
144 - Improved documentation and error diagnostics.
145 - The build of para_server is now optional, allowing the build
146 to succeed in case libosl is not installed.
147
148 ------------------------------------------
149 0.4.4 (2010-08-06) "persistent regularity"
150 ------------------------------------------
151
152 Support for yet another audio format, para_write improvements and
153 bug fixes.
154
155 - Support for the speex codec.
156 - Support for sample formats other than 16 bit little endian.
157 - error2.h is now created by a perl script which speeds up configure
158 considerably.
159 - Fix a bug in the aac decoder which could lead to segfaults in
160 para_filter/para_audiod.
161 - Fixes for autoconf-2.66.
162
163 ----------------------------------------
164 0.4.3 (2010-07-05) "imaginary radiation"
165 ----------------------------------------
166
167 Many improvements for the DCCP and the UDP transport, the new user
168 manual and the usual mix of bug fixes and internal improvements.
169
170 - FEC support for the DCCP sender (Gerrit Renker). The new
171 --dccp_max_slice_size, --dccp_data_slices_per_group and
172 --dccp_slices_per_group options can be used to set the FEC
173 parameters for the DCCP transport.
174 - DNS lookups for UDP targets (Gerrit Renker).
175 - The new user manual replaces the README, README.afs, REQUIREMENTS
176 and INSTALL documents.
177 - Fix an end-of-file detection bug in the oggdec filter.
178 - The new nonblock API.
179 - Both options of the oggdec filter have been removed.
180 - New debug mode for the internal scheduler.
181
182 ------------------------------------------
183 0.4.2 (2010-04-23) "associative expansion"
184 ------------------------------------------
185
186 It's been some time since the last release, but finally here is
187 paraslash-0.4.2. The bulk of the changes comes from the new buffer
188 tree API, but there are changes all over the tree. Mainly performance
189 and usability improvements, but also quite some bug fixes.
190
191 - The new buffer tree API.
192 - DCCP: Support for CCID negotiation (Gerrit Renker).
193 - UDP robustness fixes.
194 - The --bufsize option for mp3dec is gone as it no longer makes sense
195 for the new buffer tree API.
196 - Fix audible buffer underruns for wma streams.
197 - The alsa writer no longer prints meaningless underrun durations.
198 - audiod: Defaults work also for udp streams. If no filter is
199 given for an audio format that is received via upd, fecdec is
200 automatically added as the first filter (along with the decoder).
201
202 ---------------------------------------
203 0.4.1 (2009-12-22) "concurrent horizon"
204 ---------------------------------------
205
206 Support for another audio format, minor feature enhancements and lots of bug
207 fixes. All fixes that have been accumulated in the maint branch (in particular
208 those mentionened in the 0.3.6 release notes) appear in this release as well.
209
210 - wma support.
211 - new afh option: --human to activate human-readable output.
212 - new server/audiod option: --log-timing to print timing information.
213 - build system improvements.
214 - source code documentation updates.
215
216 -------------------------------------
217 0.3.6 (2009-12-07) "cubic continuity"
218 -------------------------------------
219
220 Quite a few bugs have been found and fixed since 0.3.5, so here's
221 another 0.3.x release. No new features.
222
223 - Always check return value of malloc().
224 - ogg vorbis/FEC: Do not write garbage after the audio file header.
225 - exit if root privileges could not be dropped.
226 - FEC: Fix computation of extra slices.
227 - oss: Fix check for empty input buffer.
228 - Avoid buffer underruns due to filter chain output buffer constraints.
229 - server: Fix assignment of afs_pid.
230 - Don't panic if the afs database contains unknown audio formats.
231 - http/dccp: Do not send the audio file header twice.
232 - FEC: Timing improvements.
233
234 ----------------------------------------------
235 0.4.0 (2009-11-10) "simultaneous independence"
236 ----------------------------------------------
237
238 Two significant changes which require the new version number: The
239 improved authentication dialog and the fact that the database code
240 has been moved to a library, libosl. To use the new version, you have
241 to generate new RSA keys, see INSTALL for details. A shell script is
242 provided for conversion of the 0.3 database to the new 0.4 format.
243
244 - stronger crypto for client authentication
245 - the database code has been moved to a library
246 - improved status item handling
247 - cleanup of the build system
248 - The "-V" option now also prints the git version
249 - the new parser-friendly listing mode for the ls and stat commands
250 - mandatory rc4 encryption
251 - major audio format handler cleanups
252 - (id3,...) tags are no longer stored as a combined string in the database
253 - new mood methods: artist_matches, title_matches, comment_matches,
254 album_matches, year_maches, year.
255
256 --------------------------------------------
257 0.3.5 (2009-09-21) "symplectic separability"
258 --------------------------------------------
259
260 Full client support for *BSD Unixes, complete re-write of the ogg
261 vorbis audio format handler, various improvements all over the place
262 and the usual mix of bugfixes. This release marks the end of the 0.3
263 series if no serious problems show up.
264
265 - the new oss writer (supported on *BSD and Linux)
266 - rewrite of the ogg vorbis audio format handler. It's
267 recommended to replace the chunk tables of existing ogg
268 vorbis files in the afs database by re-adding these files
269 with "add -f".
270 - support for netmask subsets (Gerrit Renker)
271 - the new prebuffer filter
272 - improved signal handling
273 - variable fec output buffer size
274 - improved FEC timing fixes audible buffer underruns in UDP mode
275 - --log_color actually works
276 - new ls option: -d (print dates as seconds after the epoch)
277 - update to gengetopt 2.22.2
278 - support for RSA keys of size > 512 bits
279 - new option "mixer_channel" for para_fade
280
281 -----------------------------------------
282 0.3.4 (2009-05-07) "elliptic inheritance"
283 -----------------------------------------
284
285 The new udp sender, forward error correction, colored logs and various
286 other improvements. As the udp sender does not depend on any special
287 libraries, it is built unconditionally.
288
289 - The udp sender replaces the ortp sender. The new code uses forward
290 error correction to protect against packet losses. Many thanks to
291 Gerrit Renker for providing ipv6 support.
292 - The default port for udp streaming now defaults to 8000, like
293 for the http and the dccp senders/receivers.
294 - Loglevels are now specified as symbolic names, e.g.
295 "--loglevel info".
296 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
297 - para_server/para_audiod: Color support for log messages.
298 - new options for mp3dec: --ignore-crc, --bufsize
299 - new audiod option: --config-file.
300 - gengetopt cleanups.
301 - Improved help/man pages: The documentation of para_audiod,
302 para_recv, para_filter and para_write now also contains
303 all options of the available receivers/filters/writers. The
304 man page of para_fade contains a description of the different
305 modes of operation.
306 - More source code documentation.
307 - vss timing fixes.
308
309 --------------------------------------------
310 0.3.3 (2008-12-01) "axiomatic perspectivity"
311 --------------------------------------------
312
313 Internal code cleanups, bug fixes, improved tag handling and the new
314 amplification filter.
315
316 - para_server uses the generic scheduling code.
317 - overhaul of the virtual streaming system.
318 - mp3: id3 version 2 support via libid3tag (optional)
319 - ogg: vorbis comment support.
320 - aac meta info support.
321 - mp3 audio format handler cleanups.
322 - new filter: "amp" to amplify the amplitude of the audio stream
323 - new status item/database entry: amplification. It is
324 used by the amp filter to pre-amplify the audio stream.
325 - fix a close-without-open bug in para_write.
326 - fix a bug in com_init() which was introduced in 0.3.2.
327 - better error diagnostics for para_client.
328
329 -----------------------------------------
330 0.3.2 (2008-04-11) "probabilistic parity"
331 -----------------------------------------
332
333 The new para_afh executable, scheduling and documentation improvements.
334
335 - new ls option: -lc (list chunk table)
336 - new executable: para_afh, the stand-alone audio file handler tool
337 - afs commands can send output more than SHMMAX (32MB on Linux). This
338 also reduces the memory usage of commands that produce large amounts
339 of output.
340 - major scheduler and audiod cleanups.
341 - more detailed and much nicer man pages.
342
343 ---------------------------------------
344 0.3.1 (2008-02-23) "liquid interaction"
345 ---------------------------------------
346
347 A mix of cleanups, bug fixes, improvements, and some new features. No
348 significant changes to the new database (osl) code, which is generally
349 a good sign.
350
351 - Share some similar/duplicate code between the http and the
352 dccp sender.
353 - Generic access control lists for paraslash senders.
354 - dccp sender: Access control lists, connection limiting and support
355 for the allow,deny,on,off,help sender commands.
356 - The default dccp port changed from 5001 to 8000 (suggested by
357 Gerrit Renker).
358 - para_server starts even if not all public keys could be loaded.
359 - Audiod performance improvements.
360 - fix a bug in the "off" command of the http sender.
361 - fix some fd and memory leaks.
362 - Update to gengetopt-2.22.
363
364 -------------------------------------
365 0.3.0 (2008-01-12) "solar saturation"
366 -------------------------------------
367
368 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
369
370
371 Usually one might expect lots of new features AND a big increase in size
372 for a major release like this.
373
374 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
375 ever. The decrease in size is mostly due to the removal of some
376 graphical tools (which were only quick hacks anyway). But also the
377 fact that the mysql code is gone cuts down the size a bit.
378
379 Being independent of mysql comes at a cost: The fact that paraslash
380 now contains its own database (the object storage layer, osl) increases
381 the (stripped) binary size of para_server by ~50K on i386.
382
383 - no more restrictions on unique basenames.
384 - independent of mysql: The new self-contained object
385 storage layer (osl) replaces the mysql database.
386 - New executable para_fsck: Check integrity of osl tables.
387 - Lyrics support.
388 - Reliable audio file move/rename detection.
389 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
390 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
391 Solaris (sparc64).
392 - the new osl-based audio file selector (afs) replaces the random,
393 the playlist and the mysql selector of paraslash-0.2.x.
394 - IPv6 support (thanks to Gerrit Renker).
395 - paraslash-0.2.x streams are now called "moods". Writing
396 0.3.x-mood definitions should be both easier and more
397 powerful than writing 0.2.x-stream definitions.
398 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
399 been removed. The world is a better place without them. However,
400 para_gui is still there.
401 - afs tracks audio file selection also in playlist mode.
402 - few easy-to-use afs commands replace the many not-so-easy-to-use
403 mysql commands (and are available also in playlist mode).
404 - Improved error subsystem.
405 - The earth-shaking new logo.
406
407 -----------------------------------------
408 0.2.17 (2007-11-20) "isotropic threshold"
409 -----------------------------------------
410
411 Mainly bugfixes and cleanups in this version which marks the end of
412 the 0.2.x series if no serious bugs show up after the release.
413
414 - mysql_selector: fix a locking bug.
415 - universal chunk queueing.
416 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
417 to Gerrit Renker).
418 - be more carful wrt. signed vs. unsigned argument passing.
419 - cleanup error.h and fix some references to invalid error
420 codes.
421 - update to gengetopt-2.21.
422 - update to ortp-0.13.1.
423 - autoconf: extend checks for headers, library functions and
424 compiler characteristics.
425 - Fix streaming of large mp3 files.
426 - Fix an off-by-one bug in playlist handling.
427
428 --------------------------------------
429 0.2.16 (2007-04-05) "neural discharge"
430 --------------------------------------
431
432 The main change in this release is the major audio format handler
433 cleanup which removes some similar/duplicate code and makes it easier
434 to implement plugins for other audio formats. Of course, the usual mix
435 of other improvements/changes/bugfixes also made it into the release.
436
437 - simplified audio format handlers (most of the handling functions
438 were moved one layer up to the virtual streaming system).
439 - para_server uses mmap to read audio files
440 - repositioning of mp3 streams is much faster, in particular for
441 jumping near the end of large mp3 files.
442 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
443 and AFS_WRITE.
444 - fix a bug in para_filter that caused decoding of aac files
445 to start only after a few seconds.
446 - fix osx_writer hangs
447 - simplified dccp code (thanks to Gerrit Renker)
448 - the compress filter works also on big endian systems (ppc)
449
450 -----------------------------------------
451 0.2.15 (2007-02-16) "inductive resonance"
452 -----------------------------------------
453
454 Minor improvements, more documentation and a bunch of bug fixes.
455
456 - para_server: The server.users file is only read once on server
457 startup rather than for each connection
458 - mp3dec: Fix decoding of corrupt mp3 files
459 - afs (audio file sender) is now called vss (virtual streaming
460 system). Consequently, the permission flags specified in
461 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
462 become VSS_READ and VSS_WRITE respectively.
463 - para_audiod/para_filter: Fix a bug that caused the last chunk
464 of audio data not being written under certain circumstances
465 - audiod: compute the difference of server time and local time
466 correctly
467 - para_server/para_audiod: Fix some memory leaks
468 - documentation improvements
469 - configure.ac: fix checks for para_krell
470 - new man pages
471
472 -------------------------------------------
473 0.2.14 (2006-10-15) "transient singularity"
474 -------------------------------------------
475
476 The only major enhancement of this version is the osx writer which completes
477 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
478 until now for reasons beyond the scope of this changelog entry.
479
480 - new output plugin for Mac Os: the osx writer
481 - rename configure command line options from --enable-xxx-headers to
482 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
483 - configure: new command line options: --with-mad-headers,
484 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
485 - some robustness fixes
486 - dymamic audio format recognition for audiod
487 - para_server: new command line option: --autoplay_delay
488 - para_audiod: new command line option: --clock_diff_count
489
490 ---------------------------------------
491 0.2.13 (2006-07-14) "sonic convolution"
492 ---------------------------------------
493
494 A bunch of new features and core changes.
495
496 - the new paraslash scheduler, short and sweet.
497 - Support for m4a/mp4 files via the new aac audio format
498 handler/filter (requires libfaad).
499 - each writer has its own command line parser, just like
500 para_recv and para_filter.
501 - para_client and para_audioc use the error subsystem
502 - writers are integrated in para_audiod (currently linux-only)
503 - para_client is integrated in para_audiod
504 - random/playlist selector: improved info strings
505 - new audiod commands: tasks, kill
506 - update to libortp-0.10.1
507 - para_fade: wake time defaults to 8 hours from now
508 - update to autoconf-2.60
509
510
511 ------------------------------------------
512 0.2.12 (2006-05-12) "oriented abstraction"
513 ------------------------------------------
514
515 Many user-visible changes in this release and lots of new
516 features:
517
518
519 - the new optional dccp sender/receiver. It uses the datagram
520 congestion control protocol. You'll need a fairly new kernel
521 for this.
522 - paraslash works on Mac OS X (thanks to Gerd Becker)
523 - para_play renamed to para_write
524 - modular output plugin design (writers) for para_write
525 - new file_writer output plugin for para_write
526 - compress filter speed improvements
527 - update to libortp-0.9.1
528 - update to gengetopt-2.17rc
529 - para_client no longer depends on libreadline (as the
530 code for the interactive mode was removed).
531 - gcc-2-95 is no longer a supported compiler. It may still
532 work, but it gets no more testing.
533 - the tarball no longer contains the screenshot images which
534 reduces its size quite a bit.
535 - configure: new command line options: --enable-mysql-headers
536 and --enable-mysql-libs
537
538 ------------------------------------
539 0.2.11 (2006-03-11) "atomic duality"
540 ------------------------------------
541
542 Here it is, the first paraslash release developed with git. There
543 are fairly many user-visible changes in this release. As two out of
544 the three "database tools" of paraslash don't use a database at all,
545 they are now called "audio file selectors" instead.
546
547
548 - the cdt command (change database tool) becomes chs (change
549 selector)
550 - no more colon separators: The syntax of some options of
551 para_audiod and para_filter have changed. Use --help for
552 more info (and some examples).
553 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
554 - switch from cvs to git (should've done that earlier)
555 - the new ipc subsystem
556 - new audio file selector: playlist
557 - para_server: the dopey selector is now called "random",
558 and is the default selector. Use the --selector option to
559 choose another selector at startup, or the chs command to
560 change the selector at runtime.
561 - X86_64 fixes (thanks to Steffen Klassert)
562 - para_play fixes
563
564
565 --------------------------------------
566 0.2.10 (2006-02-17) "cyclic attractor"
567 --------------------------------------
568
569 Huge documentation update, a scrollable window for para_gui, ortp
570 improvements, and of course many small fixes not mentioned here.
571 The diffstat below is rather misleading as most insertions are due
572 to the new source documentation.
573
574 - autoconf cleanup
575 - para_server also uses the new error subsystem
576 - lots of new documentation (UTSL)
577 - gui improvements:
578 - keysyms for cursor keys and for next/previous page keys
579 - scrollable output window
580 - new internal commands: scroll up/down, page up/down
581 - fix color of command output.
582 - ortp: the --chunk_time and --header flags are no longer needed
583 for para_recv/para_audiod as this information is now encoded in
584 each rtp packet sent by para_server.
585
586
587 -------------------------------------------
588 0.2.9 (2006-01-24) "progressive turbulence"
589 -------------------------------------------
590
591 Internal audiod receivers/filters, the new error subsystem and
592 a lot of small improvements.
593
594 - para_recv and para_filter are integrated into the para_audiod
595 binary, i.e. audiod no longer spawns a new process for
596 each receiver/filter. As para_recv and para_filter might be
597 useful as standalone programs, they still get built (linked
598 against the same object files that are also used for audiod).
599 - further ortp timing improvements should reduce the CPU usage
600 of the ortp receiver.
601 - improved audio grabbing. The 'grab' command of para_audiod
602 has its own set of command line options. Read the output of
603 "para_audioc help grab" for more info.
604 - oggdec: configurable input prebuffer size.
605 - the new error subsystem gives better error diagnostics
606 and reduces code size.
607
608
609 -----------------------------------------
610 0.2.8 (2006-01-02) "dynamic accumulation"
611 -----------------------------------------
612
613 The new modular filter design and the para_play-hangs bugfix.
614
615 - new executable: para_filter. It combines para_mp3dec,
616 para_oggdec and para_compress. It also adds a further filter
617 type, wav, that just inserts a wave header at the desired point
618 of the filter chain. All 'piping' is done in-memory (i.e. no
619 read/write operations are used).
620 - para_play: fix a stupid bug that caused it to hang under
621 certain circumstances.
622
623
624 -------------------------------------------
625 0.2.7 (2006-12-27) "transparent invariance"
626 -------------------------------------------
627
628 Not many user-visible changes but a fair amount of internal improvements.
629
630
631 - The http sender buffers data if it can not be sent
632 out immediately (because the socket is not writable). This
633 should prevent para_server from shutting down the connection
634 too early on a loaded network.
635 - para_play also prebuffers data if it is told to start at a
636 future time by the --start_time option.
637 - The return of para_recv: It combines para_ortp_recv and
638 para_http_recv. Use the --receiver option to switch between
639 the two. para_recv builds without libortp, but contains
640 only the http receiver in this case.
641 - update to ortp 0.8.1. As this ortp release contains incompatible
642 changes, para_recv-0.2.7 won't link against older ortp libs.
643 - improved ortp timings.
644 - use of gcc-extensions that #define away for non-gcc and
645 gcc < 3.0.
646
647
648 -------------------------------------------
649 0.2.6 (2005-10-29) "recursive compensation"
650 -------------------------------------------
651
652 Transparent session encryption (uses openssl's Alleged RC4 cipher),
653 the internal find command and several other improvements and cleanups.
654
655 - Encrypt the session if encryption is requested by the client
656 (default for para_client 0.2.6). This is backwards
657 compatible, so older clients can still connect to para_server
658 0.2.6. Use the new client option --plain to request an
659 uncrypted session (off by default, must be set to on in
660 order to connect to para_server 0.2.x with 0 <= x <= 5).
661 - para_server uses an internal function to locate audio files
662 rather than calling find(1). The server option
663 --mysql_audio_file_dir replaces --mysql_find_cmd.
664 - documentation update
665 - man pages
666 - header file cleanup
667 - para_client code cleanup
668 - para_gui: faster display of output of display commands
669
670
671 ------------------------------------------
672 0.2.5 (2005-10-13) "aggressive resolution"
673 ------------------------------------------
674
675 This release adds internal senders, i.e. no more external programs are
676 spawned for sending out the audio data. There are two different senders
677 available: The http sender and the ortp sender (former para_send which
678 is no longer needed).
679
680 The new sender code has a plugin-like design so it can be easily
681 extended should there be be any future need for supporting another
682 network streaming protocol. All senders are completely independent of
683 each other. In particular, the http and the ortp sender can operate
684 in parallel.
685
686 - new server command: sender to control senders at runtime.
687 Read the output of "para_server -h" and "para_client help
688 sender" for more information.
689 - para_recv renamed to para_ortp_recv
690 - new executable: para_http_recv, a simple command line
691 http receiver.
692 - major afs/mp3/ogg code simplifications due to internal
693 senders.
694 - ogg timing improvements
695 - fix several minor memory leaks (found by valgrind)
696 - empty stream definitions work again
697 - com_ne(): ignore errors on remove
698 - audiod: fix segfault on server restart
699
700
701 ---------------------------------------
702 0.2.4 (2005-09-21) "toxic anticipation"
703 ---------------------------------------
704
705 Several small improvements, fixes and the new grab command.
706
707 - audiod:
708 - new command: "grab" to grab the output of the stream reader
709 or any filters. Read the output of "para_audioc help grab"
710 for more information.
711 - fix memory leak
712 - code cleanup
713 - audioc: new command line option: --bufsize to specify a
714 buffer size different from the default size 8192.
715 - improved error diagnostics for para_play.
716 - new configure option: --enable-ssldir so search for openssl in
717 non-standard places
718 - sdl_gui: Make it look nice again for 1024x768
719 - server: report total size of memory allocated with sbrk by malloc,
720 new command line option: --announce_time
721
722
723 -----------------------------------------
724 0.2.3 (2005-09-01) "hydrophilic movement"
725 -----------------------------------------
726
727 Two new executables and major feature enhancements.
728
729 - audiod filters: It is now possible to specify arbitrary many
730 (including none) filters for each supported audio
731 format. This can be used e.g. for normalizing volume,
732 transforming or grabbing the audio stream, or for using
733 visualizers. Read the output of "para_audiod -h" for the
734 syntax of the new --filter_cmd option.
735 - new executable: para_play, a tiny alsa player. It
736 can play wave files or raw pcm (16 bit little endian)
737 from stdin.
738 - new executable: para_compress, a dynamic range compressor
739 intended to keep audio output at a consistent volume. Derived
740 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
741 - audiod: New option: --stream_delay. This can be used in
742 a local network to syncronize the audio output of all
743 clients that play the same stream.
744
745
746 ------------------------------------------
747 0.2.2 (2005-08-19) "tangential excitation"
748 ------------------------------------------
749
750 Mostly internal changes in this release, but also some new commands
751 for the mysql database tool.
752
753 - cleanup exec.c, fix para_exec bug
754 - compile time loglevel (log messages below the given level
755 won't be compiled in, which reduces the size of the
756 resulting binaries)
757 - new log macros that shorten the size of the source code.
758 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
759 to send only zeros. With this workaround, para_audioc works
760 again.
761 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
762 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
763 (new entry), "snp" (set numplayed). Read the manual for more
764 information.
765
766
767 ---------------------------------------
768 0.2.1 (2005-08-15) "surreal experience"
769 ---------------------------------------
770
771 Here comes paraslash-0.2.1. It contains a couple of new features and,
772 surprise, only minor bug fixes.
773
774 - kill noisy mp3 debug message
775 - cleanup of the build system
776 - para_server and para_client directly use the crypto routines
777 of the openssl library rather than invoking the openssl command
778 line utitlity
779 - server/audiod: new option --user to switch to the given user
780 when invoked as root. Read the output of "para_server -h" for
781 more information.
782 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
783 status. Default: "para_audioc stat"
784 - sdl_gui: new option --pic_cmd to be used to download the picture.
785 Default: "para_client pic"
786 - audiod: 5 slots ought to be enough for everybody
787 - audiod: new status item: Uptime, kill hup command
788
789
790
791 ------------------------------------------
792 0.2.0 (2005-08-06) "distributed diffusion"
793 ------------------------------------------
794
795 After several month of increased development activity, paraslash-0.2.0
796 has arrived. It contains many new features and is much more
797 self-contained than the old 0.1.x series. Enjoy!
798
799
800 - para_server: fix hang on song change and crash on sighup.
801 Speed up mysql queries. The DIR_LIKE macro is gone.
802 - new executables: para_audiod, the local audio daemon that
803 starts playback (uses SCM_CREDENTIALS socket magic) and
804 para_audioc, the corresponding client.
805 - new executables: para_mp3dec/para_oggdec, two really teensy
806 decoders. para_mp3dec is based on libmad, para_oggdec requires
807 libvorbisfile.
808 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
809 they are now called para_send and para_recv respectively.
810 - documentation updates
811 - para_gui is themable. For now there is the default theme that
812 looks as before and the simple theme: blue and easy.
813 - gui: audio streaming is now handled by audiod. Time display shows
814 playback time rather than streaming time
815 - slider: update to libzmw-0.2.0
816 - para_krell: fix crash on server shutdown
817 - switch from gzip to bzip2
818
819
820 ----------------------------------------
821 0.1.7 (2005-04-18) "melting penetration"
822 ----------------------------------------
823
824 The main change in this release is clearly the oggvorbis rewrite,
825 but there are also lots of smaller changes. If you intend to use both
826 the mp3 and the ogg plugin, it is recommended to use software mixing,
827 e.g. the dmix plugin which is provided by ALSA.
828
829 - new executables: para_ovsend and para_ovrecv for sending/receiving
830 oggvorbis files via rtp. Requires the open rtp library. Get it at
831 http://www.linphone.org/ortp/
832 - rewrite of the ogg_vorbis core code
833 - configure detects libzmw and, if detected, includes
834 para_slider to the list of binaries to be built by make
835 - server stream writers read from their associated fifo rather
836 than from stdin
837 - slider: two new sliders, lastplayed and numplayed
838 - fix nasty double free bug which caused random segfaults in case of
839 mp3 files with invalid header information
840 - gui: new command line option: --stream_timeout=seconds to
841 deactivate a slot if it is idle for that many seconds (default=`5')
842 - diffstats
843
844
845 ---------------------------------------
846 0.1.6 (2005-03-05) "asymptotic balance"
847 ---------------------------------------
848
849 Only little user-visible changes in this release. Mainly bugfixes and
850 core code cleanup. This is probably the most stable version ever if you
851 stick to mp3...
852
853 - fix several memory leaks
854 - rename default name of mysql database from "music" to "paraslash".
855 Use para_server's --mysql_database option if you do not want to
856 rename your old database.
857 - rework ogg vorbis code
858 - make update command work on mysql servers with LOCAL_INFILE
859 disabled
860 - gui: improved stream I/O (slots)
861 - simplified audio format API
862 - para_pob_ogg is gone
863
864 ------------------------------------
865 0.1.5 (2004-12-31) "opaque eternity"
866 ------------------------------------
867
868 Let's slide gently into the new year.
869
870 - new: para_slider (not built automatically, type "make
871 para_slider" to build). A toy for those who always felt that
872 creating stream definitions is difficult. See screenshots,
873 README and FEATURES for more info.
874 - improved signal handling. Fixes server segfault on SIGHUP
875 for linux kernels newer than Aug 24 2004 and makes para_gui
876 race-free.
877 - reload database tool on SIGHUP
878 - improved help message for sl
879 - do not log "broken pipe" messages as errors. They are
880 perfectly ok.
881 - fix wrong error message on permission errors
882
883 -----------------------------------------
884 0.1.4 (2004-12-19) "tunneling transition"
885 -----------------------------------------
886
887 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
888 Hopefully, most of them got wiped out with this release. Some
889 enhancements went also in.
890
891 - improved error diagnostics for all commands
892 - stradd/picadd: overwrite previous contents if entry already
893 exists, rather than returning errors
894 - stradd: use current stream if invoked without args
895 - faster (and hopefully more stable) ogg-vorbis handling
896 - para_krell: reap children to avoid zombie-flooding in case
897 no server is running
898 - si: report also server pid
899 - server: don't busy-loop if dbtool reports only invalid files.
900 - gui: CTRL+C works again, fix stream_read command line option
901 - fix pic_add, hist
902 - fix mysql dbtool startup in case no database exists
903 - many small fixes and cleanups
904
905 ---------------------------------------
906 0.1.3: (2004-12-10) "vanishing inertia"
907 ---------------------------------------
908
909 Starting from this release, the database tools are integrated in the
910 server binary. This decreases server startup time, reduces code size
911 and speeds up database commands. However, the layout of the underlying
912 mysql database changed only slightly and 0.1.3 should be backwards
913 compatible in that respect.
914
915 Visible changes:
916
917 - If mysql is not detected at compile time, or fails to init
918 at runtime, fall back to the dopey database tool which should
919 always work.
920 - para_dbtool and dbtool.conf are gone. All mysql specific
921 options are read from server.conf and are prefixed by 'mysql_'.
922 - new command: cdt (change database tool)
923 - new command line option: dbtool (choose startup database tool)
924 - The name of current stream is now stored in the database,
925 so paraslash remembers its current stream when restarted.
926 - new command: csp (change stream and play)
927 - para_gui also reports current database tool and server uptime
928
929
930 -------------------------------------------
931 0.1.2: (2004-11-28) "spherical fluctuation"
932 -------------------------------------------
933
934 Point release before the big dbtool changes go in.
935
936 - dbtool: rename ca to cam (copy all meta data). It now also
937 copies numplayed and lastplayed time as well as the picture
938 id.
939 - fix endless-loop-bug caused by mp3 files with invalid header
940
941 -----------------------------------------
942 0.1.1: (2004-11-05) "floating atmosphere"
943 -----------------------------------------
944
945 - gkrellm plugin
946 - new dbtool command: mbox. Browse your sound-file collection
947 with your favorite mail reader.
948 - several small fixes
949
950 -------------------------------------
951 0.1.0: (2204-10-22) "rotating cortex"
952 -------------------------------------
953
954 - fix logging bug for loglevel > VERBOSE
955 - fix skip command
956 - correct timings for vbr mp3s
957 - modular audio format support
958 - ogg-vorbis support (experimental)
959 - new server option: autoplay
960
961 -----------------------------------------
962 0.0.99: (2004-07-25) "harmonic deviation"
963 -----------------------------------------
964
965 - rename projectname from icc to paraslash (play, archive, rate
966 and stream large audio sets happily)
967 - paraslash is no longer restricted to one particular audio
968 streaming software
969 - new dbtool commands (stradd, strq, strdel) for easy stream
970 managment w/o configuration file. That obsoletes stream_defs
971 file/config option for dbtool.
972 - picadd accepts jpeg data from stdin
973 - new server commands: ps (select previous stream), sc (song change)
974 - new default pictures for sdl_gui
975 - gui: new key_map option for binding commands and internal
976 functions to arbitrary keys, nice help screen, rip out
977 soundcard/linux specific stuff, avoid noise artefacts while jumping,
978 show silly logo on startup
979 - new executables: para_fade for fading volume, para_dbadm for
980 manipulating attributes
981 - cdb adds _all_ tables to mysql database
982 - revised and beautified documentation
983 - sample dbtool rewritten in C
984 - autoconf
985
986 ---------------------------------------------
987 0.0.98: (2003-12-26) "incremental smoothness"
988 ---------------------------------------------
989
990 - kick icecast in favour of poc. That removes some races and reduces
991 core code considerably.
992 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
993 give finer info on afs' status.
994 - gui can start decoder (see config options). Further new gui
995 commands: refresh (^L), jmp (F1-F10)
996 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
997 terminates gui. This fixes dead instances consuming memory
998 continuously.
999 - new dbtool command: verb for sending verbatim sql queries.
1000 - fix pid_list races (by removing pid_list)
1001 - codename funnies
1002
1003 --------------------
1004 0.0.97: (2003-10-26)
1005 --------------------
1006
1007 - installation prefix now defaults to /usr/local
1008 - new commands for gui: snozze, sleep and reread config
1009 - config file for gui and sdl_gui
1010 - fix problems with filenames containing funny characters
1011 (reported by Thomas Forell)
1012 - improved signal handling for gui, now it rereads conf on SIGHUP
1013 - new dbtool command: cdb (create database)
1014 - switch from argtable to gengetopt
1015 - major code cleanup and speed improvements
1016 - fix several potential buffer overflows
1017 - many small fixes and cleanups
1018
1019 -------------------
1020 0.0.96 (2003-08-30)
1021 -------------------
1022
1023 - easy stream_defs syntax
1024 - sdl_gui can display images associated to the file being played
1025 - Major feature enhancements for icc_gui including dynamic text
1026 placement and the top/bottom window design
1027 - vrfy/clean now also checks for NULL values in attributes as
1028 well as for invalid picture pointers
1029 - fix long outstanding case sensitivity bug
1030 - many small fixes and cleanups
1031
1032 -------------------
1033 0.0.95 (2003-06-29)
1034 -------------------
1035
1036 - sdl gui runs much faster
1037 - new dbtool command: ca (copy attributes)
1038 - count and display number of times the song has been played
1039 - new feature: scoring
1040 - command line options for sdl_gui
1041 - simpler syntax of streams file
1042 - decrease network traffic of stat
1043 - fix zombie bug
1044 - many small fixes and cleanups
1045
1046 -------------------
1047 0.0.94 (2003-05-04)
1048 -------------------
1049
1050 - new server command: ns (next stream)
1051 - new icc_gui command: c (change stream)
1052 - internal mp3info
1053 - stat shows also id3 tag info
1054 - new sdl based gui
1055 - log flodding bug fixed
1056 - many small fixes and cleanups
1057
1058 -------------------
1059 0.0.93 (2003-03-28)
1060 -------------------
1061
1062 - colors for icc_gui
1063 - icc_gui sets volume directly (linux only)
1064 - proper locking that fixes some races
1065 - fix security bug that caused commands to be executed even
1066 with unsufficient permissions
1067 - new command: hup to make all servers reread their configuration file
1068 - icecast meta data streaming
1069 - many small fixes and cleanups
