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

951 -------------------
952
953 - easy stream_defs syntax
954 - sdl_gui can display images associated to the file being played
955 - Major feature enhancements for icc_gui including dynamic text

958 well as for invalid picture pointers
959 - fix long outstanding case sensitivity bug
960 - many small fixes and cleanups
961
962 -------------------
963 0.0.95 (2003-06-29)
964 -------------------
965
966 - sdl gui runs much faster
967 - new dbtool command: ca (copy attributes)
968 - count and display number of times the song has been played
969 - new feature: scoring

972 - decrease network traffic of stat
973 - fix zombie bug
974 - many small fixes and cleanups
975
976 -------------------
977 0.0.94 (2003-05-04)
978 -------------------
979
980 - new server command: ns (next stream)

990 -------------------
991
992 - colors for icc_gui
993 - icc_gui sets volume directly (linux only)
994 - proper locking that fixes some races
995 - fix security bug that caused commands to be executed even
996 with unsufficient permissions
997 - new command: hup to make all servers reread their configuration file
