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

960 -------------------
961
962 - easy stream_defs syntax
963 - sdl_gui can display images associated to the file being played

967 well as for invalid picture pointers
968 - fix long outstanding case sensitivity bug
969 - many small fixes and cleanups
970
971 -------------------
972 0.0.95 (2003-06-29)
973 -------------------
974
975 - sdl gui runs much faster
976 - new dbtool command: ca (copy attributes)
977 - count and display number of times the song has been played
978 - new feature: scoring

999 -------------------
1000
1001 - colors for icc_gui
1002 - icc_gui sets volume directly (linux only)
1003 - proper locking that fixes some races
1004 - fix security bug that caused commands to be executed even
1005 with unsufficient permissions
