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