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

1013 -------------------
1014
1015 - easy stream_defs syntax
1016 - sdl_gui can display images associated to the file being played
1017 - Major feature enhancements for icc_gui including dynamic text
1018 placement and the top/bottom window design
1019 - vrfy/clean now also checks for NULL values in attributes as
1020 well as for invalid picture pointers
1021 - fix long outstanding case sensitivity bug
1022 - many small fixes and cleanups
1023
1024 -------------------
1025 0.0.95 (2003-06-29)
1026 -------------------
1027
1028 - sdl gui runs much faster
1029 - new dbtool command: ca (copy attributes)
1030 - count and display number of times the song has been played
1031 - new feature: scoring
1032 - command line options for sdl_gui
1033 - simpler syntax of streams file
1034 - decrease network traffic of stat
1035 - fix zombie bug
1036 - many small fixes and cleanups
1037
1038 -------------------
1039 0.0.94 (2003-05-04)
1040 -------------------
1041
1042 - new server command: ns (next stream)
1043 - new icc_gui command: c (change stream)
1044 - internal mp3info
1045 - stat shows also id3 tag info
1046 - new sdl based gui
1047 - log flodding bug fixed
1048 - many small fixes and cleanups
1049
1050 -------------------
1051 0.0.93 (2003-03-28)
1052 -------------------
1053
1054 - colors for icc_gui
1055 - icc_gui sets volume directly (linux only)
1056 - proper locking that fixes some races
1057 - fix security bug that caused commands to be executed even
1058 with unsufficient permissions
1059 - new command: hup to make all servers reread their configuration file
1060 - icecast meta data streaming
1061 - many small fixes and cleanups
