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