[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 - Corrupt mp3 files are handled more gracefully.
21 - sched: Optimized zero timeouts.
22 - vss timeout cleanups.
23
24 --------------------------------------
25 0.4.7 (2011-06-01) "infinite rollback"
26 --------------------------------------
27
28 The new ao writer, support for ssh RSA keys and a couple of other
29 enhancements.
30
31 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
32 platforms through the libao audio library.
33 - Support for RSA keys generated with ssh-keygen.
34 - configure: improved options for ogg/vorbis/speex.
35 - The git version reported by --version always matches HEAD.
36 - The autogen script detects the number of processors and
37 runs a parallel make if possible.
38 - Major cleanup of the crypto API.
39 - Documentation updates.
40
41 ------------------------------------------
42 0.4.6 (2011-03-31) "deterministic entropy"
43 ------------------------------------------
44
45 Lots of ogg/vorbis improvements, the new test suite, enhancements
46 for para_gui and a fair amount of other bug fixes.
47
48 - For DCCP/OGG streams the audio file header is only sent once
49 at the beginning of the stream rather than periodically
50 every five seconds. This reduces network traffic and the
51 FEC group size.
52 - The vorbis comment header is replaced by an empty dummy header
53 before the header is sent over the network. This also results in
54 less network traffic and smaller FEC groups.
55 - The new "test" make target allows to perform some sanity checks prior
56 to installing the package.
57 - ogg timing fixes and performance improvements
58 - Scheduler improvements
59 - Proper exit codes for para_write
60 - para_gui: New option --theme to select a startup theme. Several
61 other improvements and fixes.
62 - aacdec error message cleanups
63 - simplified color error handling
64
65 --------------------------------------------
66 0.4.5 (2010-12-17) "symmetric randomization"
67 --------------------------------------------
68
69 Bug fixes, internal cleanups and variable-sized FEC slices.
70
71 - Contains a fix for an invalid-free-bug in the ogg audio format
72 handler code.
73 - Switching off the DCCP sender works again.
74 - para_audiod handles crashes of para_server more robustly.
75 - Internal scheduler and writer cleanups.
76 - Reduced latency due to variable-sized FEC slices.
77 - Improved documentation and error diagnostics.
78 - The build of para_server is now optional, allowing the build
79 to succeed in case libosl is not installed.
80
81 ------------------------------------------
82 0.4.4 (2010-08-06) "persistent regularity"
83 ------------------------------------------
84
85 Support for yet another audio format, para_write improvements and
86 bug fixes.
87
88 - Support for the speex codec.
89 - Support for sample formats other than 16 bit little endian.
90 - error2.h is now created by a perl script which speeds up configure
91 considerably.
92 - Fix a bug in the aac decoder which could lead to segfaults in
93 para_filter/para_audiod.
94 - Fixes for autoconf-2.66.
95
96 ----------------------------------------
97 0.4.3 (2010-07-05) "imaginary radiation"
98 ----------------------------------------
99
100 Many improvements for the DCCP and the UDP transport, the new user
101 manual and the usual mix of bug fixes and internal improvements.
102
103 - FEC support for the DCCP sender (Gerrit Renker). The new
104 --dccp_max_slice_size, --dccp_data_slices_per_group and
105 --dccp_slices_per_group options can be used to set the FEC
106 parameters for the DCCP transport.
107 - DNS lookups for UDP targets (Gerrit Renker).
108 - The new user manual replaces the README, README.afs, REQUIREMENTS
109 and INSTALL documents.
110 - Fix an end-of-file detection bug in the oggdec filter.
111 - The new nonblock API.
112 - Both options of the oggdec filter have been removed.
113 - New debug mode for the internal scheduler.
114
115 ------------------------------------------
116 0.4.2 (2010-04-23) "associative expansion"
117 ------------------------------------------
118
119 It's been some time since the last release, but finally here is
120 paraslash-0.4.2. The bulk of the changes comes from the new buffer
121 tree API, but there are changes all over the tree. Mainly performance
122 and usability improvements, but also quite some bug fixes.
123
124 - The new buffer tree API.
125 - DCCP: Support for CCID negotiation (Gerrit Renker).
126 - UDP robustness fixes.
127 - The --bufsize option for mp3dec is gone as it no longer makes sense
128 for the new buffer tree API.
129 - Fix audible buffer underruns for wma streams.
130 - The alsa writer no longer prints meaningless underrun durations.
131 - audiod: Defaults work also for udp streams. If no filter is
132 given for an audio format that is received via upd, fecdec is
133 automatically added as the first filter (along with the decoder).
134
135 ---------------------------------------
136 0.4.1 (2009-12-22) "concurrent horizon"
137 ---------------------------------------
138
139 Support for another audio format, minor feature enhancements and lots of bug
140 fixes. All fixes that have been accumulated in the maint branch (in particular
141 those mentionened in the 0.3.6 release notes) appear in this release as well.
142
143 - wma support.
144 - new afh option: --human to activate human-readable output.
145 - new server/audiod option: --log-timing to print timing information.
146 - build system improvements.
147 - source code documentation updates.
148
149 -------------------------------------
150 0.3.6 (2009-12-07) "cubic continuity"
151 -------------------------------------
152
153 Quite a few bugs have been found and fixed since 0.3.5, so here's
154 another 0.3.x release. No new features.
155
156 - Always check return value of malloc().
157 - ogg vorbis/FEC: Do not write garbage after the audio file header.
158 - exit if root privileges could not be dropped.
159 - FEC: Fix computation of extra slices.
160 - oss: Fix check for empty input buffer.
161 - Avoid buffer underruns due to filter chain output buffer constraints.
162 - server: Fix assignment of afs_pid.
163 - Don't panic if the afs database contains unknown audio formats.
164 - http/dccp: Do not send the audio file header twice.
165 - FEC: Timing improvements.
166
167 ----------------------------------------------
168 0.4.0 (2009-11-10) "simultaneous independence"
169 ----------------------------------------------
170
171 Two significant changes which require the new version number: The
172 improved authentication dialog and the fact that the database code
173 has been moved to a library, libosl. To use the new version, you have
174 to generate new RSA keys, see INSTALL for details. A shell script is
175 provided for conversion of the 0.3 database to the new 0.4 format.
176
177 - stronger crypto for client authentication
178 - the database code has been moved to a library
179 - improved status item handling
180 - cleanup of the build system
181 - The "-V" option now also prints the git version
182 - the new parser-friendly listing mode for the ls and stat commands
183 - mandatory rc4 encryption
184 - major audio format handler cleanups
185 - (id3,...) tags are no longer stored as a combined string in the database
186 - new mood methods: artist_matches, title_matches, comment_matches,
187 album_matches, year_maches, year.
188
189 --------------------------------------------
190 0.3.5 (2009-09-21) "symplectic separability"
191 --------------------------------------------
192
193 Full client support for *BSD Unixes, complete re-write of the ogg
194 vorbis audio format handler, various improvements all over the place
195 and the usual mix of bugfixes. This release marks the end of the 0.3
196 series if no serious problems show up.
197
198 - the new oss writer (supported on *BSD and Linux)
199 - rewrite of the ogg vorbis audio format handler. It's
200 recommended to replace the chunk tables of existing ogg
201 vorbis files in the afs database by re-adding these files
202 with "add -f".
203 - support for netmask subsets (Gerrit Renker)
204 - the new prebuffer filter
205 - improved signal handling
206 - variable fec output buffer size
207 - improved FEC timing fixes audible buffer underruns in UDP mode
208 - --log_color actually works
209 - new ls option: -d (print dates as seconds after the epoch)
210 - update to gengetopt 2.22.2
211 - support for RSA keys of size > 512 bits
212 - new option "mixer_channel" for para_fade
213
214 -----------------------------------------
215 0.3.4 (2009-05-07) "elliptic inheritance"
216 -----------------------------------------
217
218 The new udp sender, forward error correction, colored logs and various
219 other improvements. As the udp sender does not depend on any special
220 libraries, it is built unconditionally.
221
222 - The udp sender replaces the ortp sender. The new code uses forward
223 error correction to protect against packet losses. Many thanks to
224 Gerrit Renker for providing ipv6 support.
225 - The default port for udp streaming now defaults to 8000, like
226 for the http and the dccp senders/receivers.
227 - Loglevels are now specified as symbolic names, e.g.
228 "--loglevel info".
229 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
230 - para_server/para_audiod: Color support for log messages.
231 - new options for mp3dec: --ignore-crc, --bufsize
232 - new audiod option: --config-file.
233 - gengetopt cleanups.
234 - Improved help/man pages: The documentation of para_audiod,
235 para_recv, para_filter and para_write now also contains
236 all options of the available receivers/filters/writers. The
237 man page of para_fade contains a description of the different
238 modes of operation.
239 - More source code documentation.
240 - vss timing fixes.
241
242 --------------------------------------------
243 0.3.3 (2008-12-01) "axiomatic perspectivity"
244 --------------------------------------------
245
246 Internal code cleanups, bug fixes, improved tag handling and the new
247 amplification filter.
248
249 - para_server uses the generic scheduling code.
250 - overhaul of the virtual streaming system.
251 - mp3: id3 version 2 support via libid3tag (optional)
252 - ogg: vorbis comment support.
253 - aac meta info support.
254 - mp3 audio format handler cleanups.
255 - new filter: "amp" to amplify the amplitude of the audio stream
256 - new status item/database entry: amplification. It is
257 used by the amp filter to pre-amplify the audio stream.
258 - fix a close-without-open bug in para_write.
259 - fix a bug in com_init() which was introduced in 0.3.2.
260 - better error diagnostics for para_client.
261
262 -----------------------------------------
263 0.3.2 (2008-04-11) "probabilistic parity"
264 -----------------------------------------
265
266 The new para_afh executable, scheduling and documentation improvements.
267
268 - new ls option: -lc (list chunk table)
269 - new executable: para_afh, the stand-alone audio file handler tool
270 - afs commands can send output more than SHMMAX (32MB on Linux). This
271 also reduces the memory usage of commands that produce large amounts
272 of output.
273 - major scheduler and audiod cleanups.
274 - more detailed and much nicer man pages.
275
276 ---------------------------------------
277 0.3.1 (2008-02-23) "liquid interaction"
278 ---------------------------------------
279
280 A mix of cleanups, bug fixes, improvements, and some new features. No
281 significant changes to the new database (osl) code, which is generally
282 a good sign.
283
284 - Share some similar/duplicate code between the http and the
285 dccp sender.
286 - Generic access control lists for paraslash senders.
287 - dccp sender: Access control lists, connection limiting and support
288 for the allow,deny,on,off,help sender commands.
289 - The default dccp port changed from 5001 to 8000 (suggested by
290 Gerrit Renker).
291 - para_server starts even if not all public keys could be loaded.
292 - Audiod performance improvements.
293 - fix a bug in the "off" command of the http sender.
294 - fix some fd and memory leaks.
295 - Update to gengetopt-2.22.
296
297 -------------------------------------
298 0.3.0 (2008-01-12) "solar saturation"
299 -------------------------------------
300
301 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
302
303
304 Usually one might expect lots of new features AND a big increase in size
305 for a major release like this.
306
307 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
308 ever. The decrease in size is mostly due to the removal of some
309 graphical tools (which were only quick hacks anyway). But also the
310 fact that the mysql code is gone cuts down the size a bit.
311
312 Being independent of mysql comes at a cost: The fact that paraslash
313 now contains its own database (the object storage layer, osl) increases
314 the (stripped) binary size of para_server by ~50K on i386.
315
316 - no more restrictions on unique basenames.
317 - independent of mysql: The new self-contained object
318 storage layer (osl) replaces the mysql database.
319 - New executable para_fsck: Check integrity of osl tables.
320 - Lyrics support.
321 - Reliable audio file move/rename detection.
322 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
323 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
324 Solaris (sparc64).
325 - the new osl-based audio file selector (afs) replaces the random,
326 the playlist and the mysql selector of paraslash-0.2.x.
327 - IPv6 support (thanks to Gerrit Renker).
328 - paraslash-0.2.x streams are now called "moods". Writing
329 0.3.x-mood definitions should be both easier and more
330 powerful than writing 0.2.x-stream definitions.
331 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
332 been removed. The world is a better place without them. However,
333 para_gui is still there.
334 - afs tracks audio file selection also in playlist mode.
335 - few easy-to-use afs commands replace the many not-so-easy-to-use
336 mysql commands (and are available also in playlist mode).
337 - Improved error subsystem.
338 - The earth-shaking new logo.
339
340 -----------------------------------------
341 0.2.17 (2007-11-20) "isotropic threshold"
342 -----------------------------------------
343
344 Mainly bugfixes and cleanups in this version which marks the end of
345 the 0.2.x series if no serious bugs show up after the release.
346
347 - mysql_selector: fix a locking bug.
348 - universal chunk queueing.
349 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
350 to Gerrit Renker).
351 - be more carful wrt. signed vs. unsigned argument passing.
352 - cleanup error.h and fix some references to invalid error
353 codes.
354 - update to gengetopt-2.21.
355 - update to ortp-0.13.1.
356 - autoconf: extend checks for headers, library functions and
357 compiler characteristics.
358 - Fix streaming of large mp3 files.
359 - Fix an off-by-one bug in playlist handling.
360
361 --------------------------------------
362 0.2.16 (2007-04-05) "neural discharge"
363 --------------------------------------
364
365 The main change in this release is the major audio format handler
366 cleanup which removes some similar/duplicate code and makes it easier
367 to implement plugins for other audio formats. Of course, the usual mix
368 of other improvements/changes/bugfixes also made it into the release.
369
370 - simplified audio format handlers (most of the handling functions
371 were moved one layer up to the virtual streaming system).
372 - para_server uses mmap to read audio files
373 - repositioning of mp3 streams is much faster, in particular for
374 jumping near the end of large mp3 files.
375 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
376 and AFS_WRITE.
377 - fix a bug in para_filter that caused decoding of aac files
378 to start only after a few seconds.
379 - fix osx_writer hangs
380 - simplified dccp code (thanks to Gerrit Renker)
381 - the compress filter works also on big endian systems (ppc)
382
383 -----------------------------------------
384 0.2.15 (2007-02-16) "inductive resonance"
385 -----------------------------------------
386
387 Minor improvements, more documentation and a bunch of bug fixes.
388
389 - para_server: The server.users file is only read once on server
390 startup rather than for each connection
391 - mp3dec: Fix decoding of corrupt mp3 files
392 - afs (audio file sender) is now called vss (virtual streaming
393 system). Consequently, the permission flags specified in
394 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
395 become VSS_READ and VSS_WRITE respectively.
396 - para_audiod/para_filter: Fix a bug that caused the last chunk
397 of audio data not being written under certain circumstances
398 - audiod: compute the difference of server time and local time
399 correctly
400 - para_server/para_audiod: Fix some memory leaks
401 - documentation improvements
402 - configure.ac: fix checks for para_krell
403 - new man pages
404
405 -------------------------------------------
406 0.2.14 (2006-10-15) "transient singularity"
407 -------------------------------------------
408
409 The only major enhancement of this version is the osx writer which completes
410 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
411 until now for reasons beyond the scope of this changelog entry.
412
413 - new output plugin for Mac Os: the osx writer
414 - rename configure command line options from --enable-xxx-headers to
415 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
416 - configure: new command line options: --with-mad-headers,
417 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
418 - some robustness fixes
419 - dymamic audio format recognition for audiod
420 - para_server: new command line option: --autoplay_delay
421 - para_audiod: new command line option: --clock_diff_count
422
423 ---------------------------------------
424 0.2.13 (2006-07-14) "sonic convolution"
425 ---------------------------------------
426
427 A bunch of new features and core changes.
428
429 - the new paraslash scheduler, short and sweet.
430 - Support for m4a/mp4 files via the new aac audio format
431 handler/filter (requires libfaad).
432 - each writer has its own command line parser, just like
433 para_recv and para_filter.
434 - para_client and para_audioc use the error subsystem
435 - writers are integrated in para_audiod (currently linux-only)
436 - para_client is integrated in para_audiod
437 - random/playlist selector: improved info strings
438 - new audiod commands: tasks, kill
439 - update to libortp-0.10.1
440 - para_fade: wake time defaults to 8 hours from now
441 - update to autoconf-2.60
442
443
444 ------------------------------------------
445 0.2.12 (2006-05-12) "oriented abstraction"
446 ------------------------------------------
447
448 Many user-visible changes in this release and lots of new
449 features:
450
451
452 - the new optional dccp sender/receiver. It uses the datagram
453 congestion control protocol. You'll need a fairly new kernel
454 for this.
455 - paraslash works on Mac OS X (thanks to Gerd Becker)
456 - para_play renamed to para_write
457 - modular output plugin design (writers) for para_write
458 - new file_writer output plugin for para_write
459 - compress filter speed improvements
460 - update to libortp-0.9.1
461 - update to gengetopt-2.17rc
462 - para_client no longer depends on libreadline (as the
463 code for the interactive mode was removed).
464 - gcc-2-95 is no longer a supported compiler. It may still
465 work, but it gets no more testing.
466 - the tarball no longer contains the screenshot images which
467 reduces its size quite a bit.
468 - configure: new command line options: --enable-mysql-headers
469 and --enable-mysql-libs
470
471 ------------------------------------
472 0.2.11 (2006-03-11) "atomic duality"
473 ------------------------------------
474
475 Here it is, the first paraslash release developed with git. There
476 are fairly many user-visible changes in this release. As two out of
477 the three "database tools" of paraslash don't use a database at all,
478 they are now called "audio file selectors" instead.
479
480
481 - the cdt command (change database tool) becomes chs (change
482 selector)
483 - no more colon separators: The syntax of some options of
484 para_audiod and para_filter have changed. Use --help for
485 more info (and some examples).
486 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
487 - switch from cvs to git (should've done that earlier)
488 - the new ipc subsystem
489 - new audio file selector: playlist
490 - para_server: the dopey selector is now called "random",
491 and is the default selector. Use the --selector option to
492 choose another selector at startup, or the chs command to
493 change the selector at runtime.
494 - X86_64 fixes (thanks to Steffen Klassert)
495 - para_play fixes
496
497
498 --------------------------------------
499 0.2.10 (2006-02-17) "cyclic attractor"
500 --------------------------------------
501
502 Huge documentation update, a scrollable window for para_gui, ortp
503 improvements, and of course many small fixes not mentioned here.
504 The diffstat below is rather misleading as most insertions are due
505 to the new source documentation.
506
507 - autoconf cleanup
508 - para_server also uses the new error subsystem
509 - lots of new documentation (UTSL)
510 - gui improvements:
511 - keysyms for cursor keys and for next/previous page keys
512 - scrollable output window
513 - new internal commands: scroll up/down, page up/down
514 - fix color of command output.
515 - ortp: the --chunk_time and --header flags are no longer needed
516 for para_recv/para_audiod as this information is now encoded in
517 each rtp packet sent by para_server.
518
519
520 -------------------------------------------
521 0.2.9 (2006-01-24) "progressive turbulence"
522 -------------------------------------------
523
524 Internal audiod receivers/filters, the new error subsystem and
525 a lot of small improvements.
526
527 - para_recv and para_filter are integrated into the para_audiod
528 binary, i.e. audiod no longer spawns a new process for
529 each receiver/filter. As para_recv and para_filter might be
530 useful as standalone programs, they still get built (linked
531 against the same object files that are also used for audiod).
532 - further ortp timing improvements should reduce the CPU usage
533 of the ortp receiver.
534 - improved audio grabbing. The 'grab' command of para_audiod
535 has its own set of command line options. Read the output of
536 "para_audioc help grab" for more info.
537 - oggdec: configurable input prebuffer size.
538 - the new error subsystem gives better error diagnostics
539 and reduces code size.
540
541
542 -----------------------------------------
543 0.2.8 (2006-01-02) "dynamic accumulation"
544 -----------------------------------------
545
546 The new modular filter design and the para_play-hangs bugfix.
547
548 - new executable: para_filter. It combines para_mp3dec,
549 para_oggdec and para_compress. It also adds a further filter
550 type, wav, that just inserts a wave header at the desired point
551 of the filter chain. All 'piping' is done in-memory (i.e. no
552 read/write operations are used).
553 - para_play: fix a stupid bug that caused it to hang under
554 certain circumstances.
555
556
557 -------------------------------------------
558 0.2.7 (2006-12-27) "transparent invariance"
559 -------------------------------------------
560
561 Not many user-visible changes but a fair amount of internal improvements.
562
563
564 - The http sender buffers data if it can not be sent
565 out immediately (because the socket is not writable). This
566 should prevent para_server from shutting down the connection
567 too early on a loaded network.
568 - para_play also prebuffers data if it is told to start at a
569 future time by the --start_time option.
570 - The return of para_recv: It combines para_ortp_recv and
571 para_http_recv. Use the --receiver option to switch between
572 the two. para_recv builds without libortp, but contains
573 only the http receiver in this case.
574 - update to ortp 0.8.1. As this ortp release contains incompatible
575 changes, para_recv-0.2.7 won't link against older ortp libs.
576 - improved ortp timings.
577 - use of gcc-extensions that #define away for non-gcc and
578 gcc < 3.0.
579
580
581 -------------------------------------------
582 0.2.6 (2005-10-29) "recursive compensation"
583 -------------------------------------------
584
585 Transparent session encryption (uses openssl's Alleged RC4 cipher),
586 the internal find command and several other improvements and cleanups.
587
588 - Encrypt the session if encryption is requested by the client
589 (default for para_client 0.2.6). This is backwards
590 compatible, so older clients can still connect to para_server
591 0.2.6. Use the new client option --plain to request an
592 uncrypted session (off by default, must be set to on in
593 order to connect to para_server 0.2.x with 0 <= x <= 5).
594 - para_server uses an internal function to locate audio files
595 rather than calling find(1). The server option
596 --mysql_audio_file_dir replaces --mysql_find_cmd.
597 - documentation update
598 - man pages
599 - header file cleanup
600 - para_client code cleanup
601 - para_gui: faster display of output of display commands
602
603
604 ------------------------------------------
605 0.2.5 (2005-10-13) "aggressive resolution"
606 ------------------------------------------
607
608 This release adds internal senders, i.e. no more external programs are
609 spawned for sending out the audio data. There are two different senders
610 available: The http sender and the ortp sender (former para_send which
611 is no longer needed).
612
613 The new sender code has a plugin-like design so it can be easily
614 extended should there be be any future need for supporting another
615 network streaming protocol. All senders are completely independent of
616 each other. In particular, the http and the ortp sender can operate
617 in parallel.
618
619 - new server command: sender to control senders at runtime.
620 Read the output of "para_server -h" and "para_client help
621 sender" for more information.
622 - para_recv renamed to para_ortp_recv
623 - new executable: para_http_recv, a simple command line
624 http receiver.
625 - major afs/mp3/ogg code simplifications due to internal
626 senders.
627 - ogg timing improvements
628 - fix several minor memory leaks (found by valgrind)
629 - empty stream definitions work again
630 - com_ne(): ignore errors on remove
631 - audiod: fix segfault on server restart
632
633
634 ---------------------------------------
635 0.2.4 (2005-09-21) "toxic anticipation"
636 ---------------------------------------
637
638 Several small improvements, fixes and the new grab command.
639
640 - audiod:
641 - new command: "grab" to grab the output of the stream reader
642 or any filters. Read the output of "para_audioc help grab"
643 for more information.
644 - fix memory leak
645 - code cleanup
646 - audioc: new command line option: --bufsize to specify a
647 buffer size different from the default size 8192.
648 - improved error diagnostics for para_play.
649 - new configure option: --enable-ssldir so search for openssl in
650 non-standard places
651 - sdl_gui: Make it look nice again for 1024x768
652 - server: report total size of memory allocated with sbrk by malloc,
653 new command line option: --announce_time
654
655
656 -----------------------------------------
657 0.2.3 (2005-09-01) "hydrophilic movement"
658 -----------------------------------------
659
660 Two new executables and major feature enhancements.
661
662 - audiod filters: It is now possible to specify arbitrary many
663 (including none) filters for each supported audio
664 format. This can be used e.g. for normalizing volume,
665 transforming or grabbing the audio stream, or for using
666 visualizers. Read the output of "para_audiod -h" for the
667 syntax of the new --filter_cmd option.
668 - new executable: para_play, a tiny alsa player. It
669 can play wave files or raw pcm (16 bit little endian)
670 from stdin.
671 - new executable: para_compress, a dynamic range compressor
672 intended to keep audio output at a consistent volume. Derived
673 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
674 - audiod: New option: --stream_delay. This can be used in
675 a local network to syncronize the audio output of all
676 clients that play the same stream.
677
678
679 ------------------------------------------
680 0.2.2 (2005-08-19) "tangential excitation"
681 ------------------------------------------
682
683 Mostly internal changes in this release, but also some new commands
684 for the mysql database tool.
685
686 - cleanup exec.c, fix para_exec bug
687 - compile time loglevel (log messages below the given level
688 won't be compiled in, which reduces the size of the
689 resulting binaries)
690 - new log macros that shorten the size of the source code.
691 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
692 to send only zeros. With this workaround, para_audioc works
693 again.
694 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
695 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
696 (new entry), "snp" (set numplayed). Read the manual for more
697 information.
698
699
700 ---------------------------------------
701 0.2.1 (2005-08-15) "surreal experience"
702 ---------------------------------------
703
704 Here comes paraslash-0.2.1. It contains a couple of new features and,
705 surprise, only minor bug fixes.
706
707 - kill noisy mp3 debug message
708 - cleanup of the build system
709 - para_server and para_client directly use the crypto routines
710 of the openssl library rather than invoking the openssl command
711 line utitlity
712 - server/audiod: new option --user to switch to the given user
713 when invoked as root. Read the output of "para_server -h" for
714 more information.
715 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
716 status. Default: "para_audioc stat"
717 - sdl_gui: new option --pic_cmd to be used to download the picture.
718 Default: "para_client pic"
719 - audiod: 5 slots ought to be enough for everybody
720 - audiod: new status item: Uptime, kill hup command
721
722
723
724 ------------------------------------------
725 0.2.0 (2005-08-06) "distributed diffusion"
726 ------------------------------------------
727
728 After several month of increased development activity, paraslash-0.2.0
729 has arrived. It contains many new features and is much more
730 self-contained than the old 0.1.x series. Enjoy!
731
732
733 - para_server: fix hang on song change and crash on sighup.
734 Speed up mysql queries. The DIR_LIKE macro is gone.
735 - new executables: para_audiod, the local audio daemon that
736 starts playback (uses SCM_CREDENTIALS socket magic) and
737 para_audioc, the corresponding client.
738 - new executables: para_mp3dec/para_oggdec, two really teensy
739 decoders. para_mp3dec is based on libmad, para_oggdec requires
740 libvorbisfile.
741 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
742 they are now called para_send and para_recv respectively.
743 - documentation updates
744 - para_gui is themable. For now there is the default theme that
745 looks as before and the simple theme: blue and easy.
746 - gui: audio streaming is now handled by audiod. Time display shows
747 playback time rather than streaming time
748 - slider: update to libzmw-0.2.0
749 - para_krell: fix crash on server shutdown
750 - switch from gzip to bzip2
751
752
753 ----------------------------------------
754 0.1.7 (2005-04-18) "melting penetration"
755 ----------------------------------------
756
757 The main change in this release is clearly the oggvorbis rewrite,
758 but there are also lots of smaller changes. If you intend to use both
759 the mp3 and the ogg plugin, it is recommended to use software mixing,
760 e.g. the dmix plugin which is provided by ALSA.
761
762 - new executables: para_ovsend and para_ovrecv for sending/receiving
763 oggvorbis files via rtp. Requires the open rtp library. Get it at
764 http://www.linphone.org/ortp/
765 - rewrite of the ogg_vorbis core code
766 - configure detects libzmw and, if detected, includes
767 para_slider to the list of binaries to be built by make
768 - server stream writers read from their associated fifo rather
769 than from stdin
770 - slider: two new sliders, lastplayed and numplayed
771 - fix nasty double free bug which caused random segfaults in case of
772 mp3 files with invalid header information
773 - gui: new command line option: --stream_timeout=seconds to
774 deactivate a slot if it is idle for that many seconds (default=`5')
775 - diffstats
776
777
778 ---------------------------------------
779 0.1.6 (2005-03-05) "asymptotic balance"
780 ---------------------------------------
781
782 Only little user-visible changes in this release. Mainly bugfixes and
783 core code cleanup. This is probably the most stable version ever if you
784 stick to mp3...
785
786 - fix several memory leaks
787 - rename default name of mysql database from "music" to "paraslash".
788 Use para_server's --mysql_database option if you do not want to
789 rename your old database.
790 - rework ogg vorbis code
791 - make update command work on mysql servers with LOCAL_INFILE
792 disabled
793 - gui: improved stream I/O (slots)
794 - simplified audio format API
795 - para_pob_ogg is gone
796
797 ------------------------------------
798 0.1.5 (2004-12-31) "opaque eternity"
799 ------------------------------------
800
801 Let's slide gently into the new year.
802
803 - new: para_slider (not built automatically, type "make
804 para_slider" to build). A toy for those who always felt that
805 creating stream definitions is difficult. See screenshots,
806 README and FEATURES for more info.
807 - improved signal handling. Fixes server segfault on SIGHUP
808 for linux kernels newer than Aug 24 2004 and makes para_gui
809 race-free.
810 - reload database tool on SIGHUP
811 - improved help message for sl
812 - do not log "broken pipe" messages as errors. They are
813 perfectly ok.
814 - fix wrong error message on permission errors
815
816 -----------------------------------------
817 0.1.4 (2004-12-19) "tunneling transition"
818 -----------------------------------------
819
820 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
821 Hopefully, most of them got wiped out with this release. Some
822 enhancements went also in.
823
824 - improved error diagnostics for all commands
825 - stradd/picadd: overwrite previous contents if entry already
826 exists, rather than returning errors
827 - stradd: use current stream if invoked without args
828 - faster (and hopefully more stable) ogg-vorbis handling
829 - para_krell: reap children to avoid zombie-flooding in case
830 no server is running
831 - si: report also server pid
832 - server: don't busy-loop if dbtool reports only invalid files.
833 - gui: CTRL+C works again, fix stream_read command line option
834 - fix pic_add, hist
835 - fix mysql dbtool startup in case no database exists
836 - many small fixes and cleanups
837
838 ---------------------------------------
839 0.1.3: (2004-12-10) "vanishing inertia"
840 ---------------------------------------
841
842 Starting from this release, the database tools are integrated in the
843 server binary. This decreases server startup time, reduces code size
844 and speeds up database commands. However, the layout of the underlying
845 mysql database changed only slightly and 0.1.3 should be backwards
846 compatible in that respect.
847
848 Visible changes:
849
850 - If mysql is not detected at compile time, or fails to init
851 at runtime, fall back to the dopey database tool which should
852 always work.
853 - para_dbtool and dbtool.conf are gone. All mysql specific
854 options are read from server.conf and are prefixed by 'mysql_'.
855 - new command: cdt (change database tool)
856 - new command line option: dbtool (choose startup database tool)
857 - The name of current stream is now stored in the database,
858 so paraslash remembers its current stream when restarted.
859 - new command: csp (change stream and play)
860 - para_gui also reports current database tool and server uptime
861
862
863 -------------------------------------------
864 0.1.2: (2004-11-28) "spherical fluctuation"
865 -------------------------------------------
866
867 Point release before the big dbtool changes go in.
868
869 - dbtool: rename ca to cam (copy all meta data). It now also
870 copies numplayed and lastplayed time as well as the picture
871 id.
872 - fix endless-loop-bug caused by mp3 files with invalid header
873
874 -----------------------------------------
875 0.1.1: (2004-11-05) "floating atmosphere"
876 -----------------------------------------
877
878 - gkrellm plugin
879 - new dbtool command: mbox. Browse your sound-file collection
880 with your favorite mail reader.
881 - several small fixes
882
883 -------------------------------------
884 0.1.0: (2204-10-22) "rotating cortex"
885 -------------------------------------
886
887 - fix logging bug for loglevel > VERBOSE
888 - fix skip command
889 - correct timings for vbr mp3s
890 - modular audio format support
891 - ogg-vorbis support (experimental)
892 - new server option: autoplay
893
894 -----------------------------------------
895 0.0.99: (2004-07-25) "harmonic deviation"
896 -----------------------------------------
897
898 - rename projectname from icc to paraslash (play, archive, rate
899 and stream large audio sets happily)
900 - paraslash is no longer restricted to one particular audio
901 streaming software
902 - new dbtool commands (stradd, strq, strdel) for easy stream
903 managment w/o configuration file. That obsoletes stream_defs
904 file/config option for dbtool.
905 - picadd accepts jpeg data from stdin
906 - new server commands: ps (select previous stream), sc (song change)
907 - new default pictures for sdl_gui
908 - gui: new key_map option for binding commands and internal
909 functions to arbitrary keys, nice help screen, rip out
910 soundcard/linux specific stuff, avoid noise artefacts while jumping,
911 show silly logo on startup
912 - new executables: para_fade for fading volume, para_dbadm for
913 manipulating attributes
914 - cdb adds _all_ tables to mysql database
915 - revised and beautified documentation
916 - sample dbtool rewritten in C
917 - autoconf
918
919 ---------------------------------------------
920 0.0.98: (2003-12-26) "incremental smoothness"
921 ---------------------------------------------
922
923 - kick icecast in favour of poc. That removes some races and reduces
924 core code considerably.
925 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
926 give finer info on afs' status.
927 - gui can start decoder (see config options). Further new gui
928 commands: refresh (^L), jmp (F1-F10)
929 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
930 terminates gui. This fixes dead instances consuming memory
931 continuously.
932 - new dbtool command: verb for sending verbatim sql queries.
933 - fix pid_list races (by removing pid_list)
934 - codename funnies
935
936 --------------------
937 0.0.97: (2003-10-26)
938 --------------------
939
940 - installation prefix now defaults to /usr/local
941 - new commands for gui: snozze, sleep and reread config
942 - config file for gui and sdl_gui
943 - fix problems with filenames containing funny characters
944 (reported by Thomas Forell)
945 - improved signal handling for gui, now it rereads conf on SIGHUP
946 - new dbtool command: cdb (create database)
947 - switch from argtable to gengetopt
948 - major code cleanup and speed improvements
949 - fix several potential buffer overflows
950 - many small fixes and cleanups
951
952 -------------------
953 0.0.96 (2003-08-30)
954 -------------------
955
956 - easy stream_defs syntax
957 - sdl_gui can display images associated to the file being played
958 - Major feature enhancements for icc_gui including dynamic text
959 placement and the top/bottom window design
960 - vrfy/clean now also checks for NULL values in attributes as
961 well as for invalid picture pointers
962 - fix long outstanding case sensitivity bug
963 - many small fixes and cleanups
964
965 -------------------
966 0.0.95 (2003-06-29)
967 -------------------
968
969 - sdl gui runs much faster
970 - new dbtool command: ca (copy attributes)
971 - count and display number of times the song has been played
972 - new feature: scoring
973 - command line options for sdl_gui
974 - simpler syntax of streams file
975 - decrease network traffic of stat
976 - fix zombie bug
977 - many small fixes and cleanups
978
979 -------------------
980 0.0.94 (2003-05-04)
981 -------------------
982
983 - new server command: ns (next stream)
984 - new icc_gui command: c (change stream)

993 -------------------
994
995 - colors for icc_gui
996 - icc_gui sets volume directly (linux only)
997 - proper locking that fixes some races
998 - fix security bug that caused commands to be executed even
999 with unsufficient permissions
1000 - new command: hup to make all servers reread their configuration file
