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

983 -------------------
984
985 - easy stream_defs syntax
986 - sdl_gui can display images associated to the file being played
987 - Major feature enhancements for icc_gui including dynamic text
988 placement and the top/bottom window design
989 - vrfy/clean now also checks for NULL values in attributes as
990 well as for invalid picture pointers
991 - fix long outstanding case sensitivity bug
992 - many small fixes and cleanups
993
994 -------------------
995 0.0.95 (2003-06-29)
996 -------------------
997
998 - sdl gui runs much faster
999 - new dbtool command: ca (copy attributes)
1000 - count and display number of times the song has been played
1001 - new feature: scoring

1003 - simpler syntax of streams file
1004 - decrease network traffic of stat
1005 - fix zombie bug
1006 - many small fixes and cleanups
1007
1008 -------------------
1009 0.0.94 (2003-05-04)
1010 -------------------
1011
1012 - new server command: ns (next stream)

1016 - new sdl based gui
1017 - log flodding bug fixed
1018 - many small fixes and cleanups
1019
1020 -------------------
1021 0.0.93 (2003-03-28)
1022 -------------------
1023
1024 - colors for icc_gui
1025 - icc_gui sets volume directly (linux only)
1026 - proper locking that fixes some races
1027 - fix security bug that caused commands to be executed even
1028 with unsufficient permissions
1029 - new command: hup to make all servers reread their configuration file
1030 - icecast meta data streaming
1031 - many small fixes and cleanups
