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

976 -------------------
977
978 - easy stream_defs syntax
979 - sdl_gui can display images associated to the file being played
980 - Major feature enhancements for icc_gui including dynamic text
981 placement and the top/bottom window design
982 - vrfy/clean now also checks for NULL values in attributes as
983 well as for invalid picture pointers
984 - fix long outstanding case sensitivity bug
985 - many small fixes and cleanups
986
987 -------------------
988 0.0.95 (2003-06-29)
989 -------------------
990
991 - sdl gui runs much faster
992 - new dbtool command: ca (copy attributes)
993 - count and display number of times the song has been played
994 - new feature: scoring

997 - decrease network traffic of stat
998 - fix zombie bug
999 - many small fixes and cleanups
1000
1001 -------------------

1003 -------------------
1004
1005 - new server command: ns (next stream)

1013 -------------------
1014 0.0.93 (2003-03-28)
1015 -------------------
1016
1017 - colors for icc_gui
1018 - icc_gui sets volume directly (linux only)
1019 - proper locking that fixes some races
1020 - fix security bug that caused commands to be executed even
1021 with unsufficient permissions
1022 - new command: hup to make all servers reread their configuration file
1023 - icecast meta data streaming
1024 - many small fixes and cleanups
