[paraslash.git] / NEWS
1 -------------------------------------------
2 0.4.11 (to be announced) "mutual diversity"
3 -------------------------------------------
4
5 - Sideband connections: If both para_server and para_client
6 support this feature, data is sent as a multiplexed stream.
7 - The --no_default_filters option of para_filter has been
8 removed.
9 - Several fixes and latency improvements to various decoders.
10 - The alsa writer now limits the prebuffer time to 500ms.
11 - Documentation improvements.
12 - Overhaul of the command_util.sh script.
13 - Fixes for some minor problems found by the clang analyzer.
14
15 ------------------------------------------
16 0.4.10 (2012-03-30) "heterogeneous vacuum"
17 ------------------------------------------
18
19 Nothing earth-shaking in this release, but quite a few usability
20 improvements and the usual mix of cleanups and fixes.
21
22 - The --no_default_filters option of para_filter has been
23 deprecated. It still works but has no effect and will be
24 removed in the next version.
25 - para_gui now prints also the stderr output of the executing
26 command in the bottom window.
27 - Cleanup and consolidation of the various wrappers for
28 write(), writev(), send() and friends.
29 - The obscure error messages on mmap() failures have been
30 replaced by meaningful messages. This affects mainly
31 para_afh.
32 - para_audioc: Cleanups and memory leak fixes.
33 - Test 0004-server no longer fails if para_server is not
34 being built.
35 - New configure options: --with-id3tag-{headers,libs}.
36
37 -------------------------------------
38 0.4.9 (2011-12-06) "hybrid causality"
39 -------------------------------------
40
41 Support for another audio format, interactive mode for para_client
42 and para_audiod and many small improvements/fixes all over the place.
43
44 - Support for flac, the free lossless audio codec.
45 - Fix for an endless loop in the mp3 decoder for certain
46 (corrupt) mp3 files.
47 - When executed without specifying a command, para_client
48 and para_audioc start an interactive shell (requires
49 libreadline being installed). The interactive mode offers
50 full tab completion and command line history.
51 - autogen.sh now detects a distcc setup and adjusts the
52 parameter for the -j option of make accordingly.
53 - Shared memory areas are no longer restricted to 64K. We now
54 detect the maximal size of a shared memory area at runtime.
55 - cleanup of the internal uptime API.
56 - para_server prefaults the mmapped audio file to avoid
57 delays on slow media.
58 - A new test for the test-suite that exercises the
59 communication between para_server and para_audiod.
60 - The alsa writer eats up less CPU cycles when configured to
61 use the DMIX plugin.
62 - Simplified and unified receiver code.
63 - Makefile cleanups.
64 - Commands which print a list of matching audio files now
65 emit a meaningful error message if no audio file matched the
66 given pattern(s).
67
68 --------------------------------------
69 0.4.8 (2011-08-19) "nested assignment"
70 --------------------------------------
71
72 Gcrypt support, the overhauled osx writer and regex format specifiers
73 are the highlights of this release.
74
75 - support for libgcrypt as a drop-in replacement for openssl.
76 Run configure --enable-cryptolib=gcrypt to link against
77 libgcrypt. The two crypto implementations are compatible to
78 each other, i.e. a para_client executable linked against
79 gcrypt can connect to para_server linked against libssl
80 and vice versa.
81 - Rewrite of the osx writer (output plugin for Mac OS).
82 - audiod: The format specifier for receivers, filters and
83 writers is now treated as a regular expression. This allows
84 to replace 5 lines in the config file (one for each audio
85 format) by one single line. See the manual for details.
86 - The *.cmdline.[ch] files are no longer contained in the released
87 tarballs. This reduces the size of the tarballs but requires
88 gengetopt to build the tarball.
89 - Compiles cleanly also with llvm/clang.
90 - Corrupt mp3 files are handled more gracefully.
91 - The alsa writer uses poll fds instead of computing timeouts.
92 - Cleanup of the generic writer API.
93 - sched: Optimized zero timeouts.
94 - vss timeout cleanups.
95 - oggdec fixes and improvements.
96
97 --------------------------------------
98 0.4.7 (2011-06-01) "infinite rollback"
99 --------------------------------------
100
101 The new ao writer, support for ssh RSA keys and a couple of other
102 enhancements.
103
104 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
105 platforms through the libao audio library.
106 - Support for RSA keys generated with ssh-keygen.
107 - configure: improved options for ogg/vorbis/speex.
108 - The git version reported by --version always matches HEAD.
109 - The autogen script detects the number of processors and
110 runs a parallel make if possible.
111 - Major cleanup of the crypto API.
112 - Documentation updates.
113
114 ------------------------------------------
115 0.4.6 (2011-03-31) "deterministic entropy"
116 ------------------------------------------
117
118 Lots of ogg/vorbis improvements, the new test suite, enhancements
119 for para_gui and a fair amount of other bug fixes.
120
121 - For DCCP/OGG streams the audio file header is only sent once
122 at the beginning of the stream rather than periodically
123 every five seconds. This reduces network traffic and the
124 FEC group size.
125 - The vorbis comment header is replaced by an empty dummy header
126 before the header is sent over the network. This also results in
127 less network traffic and smaller FEC groups.
128 - The new "test" make target allows to perform some sanity checks prior
129 to installing the package.
130 - ogg timing fixes and performance improvements
131 - Scheduler improvements
132 - Proper exit codes for para_write
133 - para_gui: New option --theme to select a startup theme. Several
134 other improvements and fixes.
135 - aacdec error message cleanups
136 - simplified color error handling
137
138 --------------------------------------------
139 0.4.5 (2010-12-17) "symmetric randomization"
140 --------------------------------------------
141
142 Bug fixes, internal cleanups and variable-sized FEC slices.
143
144 - Contains a fix for an invalid-free-bug in the ogg audio format
145 handler code.
146 - Switching off the DCCP sender works again.
147 - para_audiod handles crashes of para_server more robustly.
148 - Internal scheduler and writer cleanups.
149 - Reduced latency due to variable-sized FEC slices.
150 - Improved documentation and error diagnostics.
151 - The build of para_server is now optional, allowing the build
152 to succeed in case libosl is not installed.
153
154 ------------------------------------------
155 0.4.4 (2010-08-06) "persistent regularity"
156 ------------------------------------------
157
158 Support for yet another audio format, para_write improvements and
159 bug fixes.
160
161 - Support for the speex codec.
162 - Support for sample formats other than 16 bit little endian.
163 - error2.h is now created by a perl script which speeds up configure
164 considerably.
165 - Fix a bug in the aac decoder which could lead to segfaults in
166 para_filter/para_audiod.
167 - Fixes for autoconf-2.66.
168
169 ----------------------------------------
170 0.4.3 (2010-07-05) "imaginary radiation"
171 ----------------------------------------
172
173 Many improvements for the DCCP and the UDP transport, the new user
174 manual and the usual mix of bug fixes and internal improvements.
175
176 - FEC support for the DCCP sender (Gerrit Renker). The new
177 --dccp_max_slice_size, --dccp_data_slices_per_group and
178 --dccp_slices_per_group options can be used to set the FEC
179 parameters for the DCCP transport.
180 - DNS lookups for UDP targets (Gerrit Renker).
181 - The new user manual replaces the README, README.afs, REQUIREMENTS
182 and INSTALL documents.
183 - Fix an end-of-file detection bug in the oggdec filter.
184 - The new nonblock API.
185 - Both options of the oggdec filter have been removed.
186 - New debug mode for the internal scheduler.
187
188 ------------------------------------------
189 0.4.2 (2010-04-23) "associative expansion"
190 ------------------------------------------
191
192 It's been some time since the last release, but finally here is
193 paraslash-0.4.2. The bulk of the changes comes from the new buffer
194 tree API, but there are changes all over the tree. Mainly performance
195 and usability improvements, but also quite some bug fixes.
196
197 - The new buffer tree API.
198 - DCCP: Support for CCID negotiation (Gerrit Renker).
199 - UDP robustness fixes.
200 - The --bufsize option for mp3dec is gone as it no longer makes sense
201 for the new buffer tree API.
202 - Fix audible buffer underruns for wma streams.
203 - The alsa writer no longer prints meaningless underrun durations.
204 - audiod: Defaults work also for udp streams. If no filter is
205 given for an audio format that is received via upd, fecdec is
206 automatically added as the first filter (along with the decoder).
207
208 ---------------------------------------
209 0.4.1 (2009-12-22) "concurrent horizon"
210 ---------------------------------------
211
212 Support for another audio format, minor feature enhancements and lots of bug
213 fixes. All fixes that have been accumulated in the maint branch (in particular
214 those mentionened in the 0.3.6 release notes) appear in this release as well.
215
216 - wma support.
217 - new afh option: --human to activate human-readable output.
218 - new server/audiod option: --log-timing to print timing information.
219 - build system improvements.
220 - source code documentation updates.
221
222 -------------------------------------
223 0.3.6 (2009-12-07) "cubic continuity"
224 -------------------------------------
225
226 Quite a few bugs have been found and fixed since 0.3.5, so here's
227 another 0.3.x release. No new features.
228
229 - Always check return value of malloc().
230 - ogg vorbis/FEC: Do not write garbage after the audio file header.
231 - exit if root privileges could not be dropped.
232 - FEC: Fix computation of extra slices.
233 - oss: Fix check for empty input buffer.
234 - Avoid buffer underruns due to filter chain output buffer constraints.
235 - server: Fix assignment of afs_pid.
236 - Don't panic if the afs database contains unknown audio formats.
237 - http/dccp: Do not send the audio file header twice.
238 - FEC: Timing improvements.
239
240 ----------------------------------------------
241 0.4.0 (2009-11-10) "simultaneous independence"
242 ----------------------------------------------
243
244 Two significant changes which require the new version number: The
245 improved authentication dialog and the fact that the database code
246 has been moved to a library, libosl. To use the new version, you have
247 to generate new RSA keys, see INSTALL for details. A shell script is
248 provided for conversion of the 0.3 database to the new 0.4 format.
249
250 - stronger crypto for client authentication
251 - the database code has been moved to a library
252 - improved status item handling
253 - cleanup of the build system
254 - The "-V" option now also prints the git version
255 - the new parser-friendly listing mode for the ls and stat commands
256 - mandatory rc4 encryption
257 - major audio format handler cleanups
258 - (id3,...) tags are no longer stored as a combined string in the database
259 - new mood methods: artist_matches, title_matches, comment_matches,
260 album_matches, year_maches, year.
261
262 --------------------------------------------
263 0.3.5 (2009-09-21) "symplectic separability"
264 --------------------------------------------
265
266 Full client support for *BSD Unixes, complete re-write of the ogg
267 vorbis audio format handler, various improvements all over the place
268 and the usual mix of bugfixes. This release marks the end of the 0.3
269 series if no serious problems show up.
270
271 - the new oss writer (supported on *BSD and Linux)
272 - rewrite of the ogg vorbis audio format handler. It's
273 recommended to replace the chunk tables of existing ogg
274 vorbis files in the afs database by re-adding these files
275 with "add -f".
276 - support for netmask subsets (Gerrit Renker)
277 - the new prebuffer filter
278 - improved signal handling
279 - variable fec output buffer size
280 - improved FEC timing fixes audible buffer underruns in UDP mode
281 - --log_color actually works
282 - new ls option: -d (print dates as seconds after the epoch)
283 - update to gengetopt 2.22.2
284 - support for RSA keys of size > 512 bits
285 - new option "mixer_channel" for para_fade
286
287 -----------------------------------------
288 0.3.4 (2009-05-07) "elliptic inheritance"
289 -----------------------------------------
290
291 The new udp sender, forward error correction, colored logs and various
292 other improvements. As the udp sender does not depend on any special
293 libraries, it is built unconditionally.
294
295 - The udp sender replaces the ortp sender. The new code uses forward
296 error correction to protect against packet losses. Many thanks to
297 Gerrit Renker for providing ipv6 support.
298 - The default port for udp streaming now defaults to 8000, like
299 for the http and the dccp senders/receivers.
300 - Loglevels are now specified as symbolic names, e.g.
301 "--loglevel info".
302 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
303 - para_server/para_audiod: Color support for log messages.
304 - new options for mp3dec: --ignore-crc, --bufsize
305 - new audiod option: --config-file.
306 - gengetopt cleanups.
307 - Improved help/man pages: The documentation of para_audiod,
308 para_recv, para_filter and para_write now also contains
309 all options of the available receivers/filters/writers. The
310 man page of para_fade contains a description of the different
311 modes of operation.
312 - More source code documentation.
313 - vss timing fixes.
314
315 --------------------------------------------
316 0.3.3 (2008-12-01) "axiomatic perspectivity"
317 --------------------------------------------
318
319 Internal code cleanups, bug fixes, improved tag handling and the new
320 amplification filter.
321
322 - para_server uses the generic scheduling code.
323 - overhaul of the virtual streaming system.
324 - mp3: id3 version 2 support via libid3tag (optional)
325 - ogg: vorbis comment support.
326 - aac meta info support.
327 - mp3 audio format handler cleanups.
328 - new filter: "amp" to amplify the amplitude of the audio stream
329 - new status item/database entry: amplification. It is
330 used by the amp filter to pre-amplify the audio stream.
331 - fix a close-without-open bug in para_write.
332 - fix a bug in com_init() which was introduced in 0.3.2.
333 - better error diagnostics for para_client.
334
335 -----------------------------------------
336 0.3.2 (2008-04-11) "probabilistic parity"
337 -----------------------------------------
338
339 The new para_afh executable, scheduling and documentation improvements.
340
341 - new ls option: -lc (list chunk table)
342 - new executable: para_afh, the stand-alone audio file handler tool
343 - afs commands can send output more than SHMMAX (32MB on Linux). This
344 also reduces the memory usage of commands that produce large amounts
345 of output.
346 - major scheduler and audiod cleanups.
347 - more detailed and much nicer man pages.
348
349 ---------------------------------------
350 0.3.1 (2008-02-23) "liquid interaction"
351 ---------------------------------------
352
353 A mix of cleanups, bug fixes, improvements, and some new features. No
354 significant changes to the new database (osl) code, which is generally
355 a good sign.
356
357 - Share some similar/duplicate code between the http and the
358 dccp sender.
359 - Generic access control lists for paraslash senders.
360 - dccp sender: Access control lists, connection limiting and support
361 for the allow,deny,on,off,help sender commands.
362 - The default dccp port changed from 5001 to 8000 (suggested by
363 Gerrit Renker).
364 - para_server starts even if not all public keys could be loaded.
365 - Audiod performance improvements.
366 - fix a bug in the "off" command of the http sender.
367 - fix some fd and memory leaks.
368 - Update to gengetopt-2.22.
369
370 -------------------------------------
371 0.3.0 (2008-01-12) "solar saturation"
372 -------------------------------------
373
374 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
375
376
377 Usually one might expect lots of new features AND a big increase in size
378 for a major release like this.
379
380 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
381 ever. The decrease in size is mostly due to the removal of some
382 graphical tools (which were only quick hacks anyway). But also the
383 fact that the mysql code is gone cuts down the size a bit.
384
385 Being independent of mysql comes at a cost: The fact that paraslash
386 now contains its own database (the object storage layer, osl) increases
387 the (stripped) binary size of para_server by ~50K on i386.
388
389 - no more restrictions on unique basenames.
390 - independent of mysql: The new self-contained object
391 storage layer (osl) replaces the mysql database.
392 - New executable para_fsck: Check integrity of osl tables.
393 - Lyrics support.
394 - Reliable audio file move/rename detection.
395 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
396 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
397 Solaris (sparc64).
398 - the new osl-based audio file selector (afs) replaces the random,
399 the playlist and the mysql selector of paraslash-0.2.x.
400 - IPv6 support (thanks to Gerrit Renker).
401 - paraslash-0.2.x streams are now called "moods". Writing
402 0.3.x-mood definitions should be both easier and more
403 powerful than writing 0.2.x-stream definitions.
404 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
405 been removed. The world is a better place without them. However,
406 para_gui is still there.
407 - afs tracks audio file selection also in playlist mode.
408 - few easy-to-use afs commands replace the many not-so-easy-to-use
409 mysql commands (and are available also in playlist mode).
410 - Improved error subsystem.
411 - The earth-shaking new logo.
412
413 -----------------------------------------
414 0.2.17 (2007-11-20) "isotropic threshold"
415 -----------------------------------------
416
417 Mainly bugfixes and cleanups in this version which marks the end of
418 the 0.2.x series if no serious bugs show up after the release.
419
420 - mysql_selector: fix a locking bug.
421 - universal chunk queueing.
422 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
423 to Gerrit Renker).
424 - be more carful wrt. signed vs. unsigned argument passing.
425 - cleanup error.h and fix some references to invalid error
426 codes.
427 - update to gengetopt-2.21.
428 - update to ortp-0.13.1.
429 - autoconf: extend checks for headers, library functions and
430 compiler characteristics.
431 - Fix streaming of large mp3 files.
432 - Fix an off-by-one bug in playlist handling.
433
434 --------------------------------------
435 0.2.16 (2007-04-05) "neural discharge"
436 --------------------------------------
437
438 The main change in this release is the major audio format handler
439 cleanup which removes some similar/duplicate code and makes it easier
440 to implement plugins for other audio formats. Of course, the usual mix
441 of other improvements/changes/bugfixes also made it into the release.
442
443 - simplified audio format handlers (most of the handling functions
444 were moved one layer up to the virtual streaming system).
445 - para_server uses mmap to read audio files
446 - repositioning of mp3 streams is much faster, in particular for
447 jumping near the end of large mp3 files.
448 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
449 and AFS_WRITE.
450 - fix a bug in para_filter that caused decoding of aac files
451 to start only after a few seconds.
452 - fix osx_writer hangs
453 - simplified dccp code (thanks to Gerrit Renker)
454 - the compress filter works also on big endian systems (ppc)
455
456 -----------------------------------------
457 0.2.15 (2007-02-16) "inductive resonance"
458 -----------------------------------------
459
460 Minor improvements, more documentation and a bunch of bug fixes.
461
462 - para_server: The server.users file is only read once on server
463 startup rather than for each connection
464 - mp3dec: Fix decoding of corrupt mp3 files
465 - afs (audio file sender) is now called vss (virtual streaming
466 system). Consequently, the permission flags specified in
467 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
468 become VSS_READ and VSS_WRITE respectively.
469 - para_audiod/para_filter: Fix a bug that caused the last chunk
470 of audio data not being written under certain circumstances
471 - audiod: compute the difference of server time and local time
472 correctly
473 - para_server/para_audiod: Fix some memory leaks
474 - documentation improvements
475 - configure.ac: fix checks for para_krell
476 - new man pages
477
478 -------------------------------------------
479 0.2.14 (2006-10-15) "transient singularity"
480 -------------------------------------------
481
482 The only major enhancement of this version is the osx writer which completes
483 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
484 until now for reasons beyond the scope of this changelog entry.
485
486 - new output plugin for Mac Os: the osx writer
487 - rename configure command line options from --enable-xxx-headers to
488 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
489 - configure: new command line options: --with-mad-headers,
490 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
491 - some robustness fixes
492 - dymamic audio format recognition for audiod
493 - para_server: new command line option: --autoplay_delay
494 - para_audiod: new command line option: --clock_diff_count
495
496 ---------------------------------------
497 0.2.13 (2006-07-14) "sonic convolution"
498 ---------------------------------------
499
500 A bunch of new features and core changes.
501
502 - the new paraslash scheduler, short and sweet.
503 - Support for m4a/mp4 files via the new aac audio format
504 handler/filter (requires libfaad).
505 - each writer has its own command line parser, just like
506 para_recv and para_filter.
507 - para_client and para_audioc use the error subsystem
508 - writers are integrated in para_audiod (currently linux-only)
509 - para_client is integrated in para_audiod
510 - random/playlist selector: improved info strings
511 - new audiod commands: tasks, kill
512 - update to libortp-0.10.1
513 - para_fade: wake time defaults to 8 hours from now
514 - update to autoconf-2.60
515
516
517 ------------------------------------------
518 0.2.12 (2006-05-12) "oriented abstraction"
519 ------------------------------------------
520
521 Many user-visible changes in this release and lots of new
522 features:
523
524
525 - the new optional dccp sender/receiver. It uses the datagram
526 congestion control protocol. You'll need a fairly new kernel
527 for this.
528 - paraslash works on Mac OS X (thanks to Gerd Becker)
529 - para_play renamed to para_write
530 - modular output plugin design (writers) for para_write
531 - new file_writer output plugin for para_write
532 - compress filter speed improvements
533 - update to libortp-0.9.1
534 - update to gengetopt-2.17rc
535 - para_client no longer depends on libreadline (as the
536 code for the interactive mode was removed).
537 - gcc-2-95 is no longer a supported compiler. It may still
538 work, but it gets no more testing.
539 - the tarball no longer contains the screenshot images which
540 reduces its size quite a bit.
541 - configure: new command line options: --enable-mysql-headers
542 and --enable-mysql-libs
543
544 ------------------------------------
545 0.2.11 (2006-03-11) "atomic duality"
546 ------------------------------------
547
548 Here it is, the first paraslash release developed with git. There
549 are fairly many user-visible changes in this release. As two out of
550 the three "database tools" of paraslash don't use a database at all,
551 they are now called "audio file selectors" instead.
552
553
554 - the cdt command (change database tool) becomes chs (change
555 selector)
556 - no more colon separators: The syntax of some options of
557 para_audiod and para_filter have changed. Use --help for
558 more info (and some examples).
559 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
560 - switch from cvs to git (should've done that earlier)
561 - the new ipc subsystem
562 - new audio file selector: playlist
563 - para_server: the dopey selector is now called "random",
564 and is the default selector. Use the --selector option to
565 choose another selector at startup, or the chs command to
566 change the selector at runtime.
567 - X86_64 fixes (thanks to Steffen Klassert)
568 - para_play fixes
569
570
571 --------------------------------------
572 0.2.10 (2006-02-17) "cyclic attractor"
573 --------------------------------------
574
575 Huge documentation update, a scrollable window for para_gui, ortp
576 improvements, and of course many small fixes not mentioned here.
577 The diffstat below is rather misleading as most insertions are due
578 to the new source documentation.
579
580 - autoconf cleanup
581 - para_server also uses the new error subsystem
582 - lots of new documentation (UTSL)
583 - gui improvements:
584 - keysyms for cursor keys and for next/previous page keys
585 - scrollable output window
586 - new internal commands: scroll up/down, page up/down
587 - fix color of command output.
588 - ortp: the --chunk_time and --header flags are no longer needed
589 for para_recv/para_audiod as this information is now encoded in
590 each rtp packet sent by para_server.
591
592
593 -------------------------------------------
594 0.2.9 (2006-01-24) "progressive turbulence"
595 -------------------------------------------
596
597 Internal audiod receivers/filters, the new error subsystem and
598 a lot of small improvements.
599
600 - para_recv and para_filter are integrated into the para_audiod
601 binary, i.e. audiod no longer spawns a new process for
602 each receiver/filter. As para_recv and para_filter might be
603 useful as standalone programs, they still get built (linked
604 against the same object files that are also used for audiod).
605 - further ortp timing improvements should reduce the CPU usage
606 of the ortp receiver.
607 - improved audio grabbing. The 'grab' command of para_audiod
608 has its own set of command line options. Read the output of
609 "para_audioc help grab" for more info.
610 - oggdec: configurable input prebuffer size.
611 - the new error subsystem gives better error diagnostics
612 and reduces code size.
613
614
615 -----------------------------------------
616 0.2.8 (2006-01-02) "dynamic accumulation"
617 -----------------------------------------
618
619 The new modular filter design and the para_play-hangs bugfix.
620
621 - new executable: para_filter. It combines para_mp3dec,
622 para_oggdec and para_compress. It also adds a further filter
623 type, wav, that just inserts a wave header at the desired point
624 of the filter chain. All 'piping' is done in-memory (i.e. no
625 read/write operations are used).
626 - para_play: fix a stupid bug that caused it to hang under
627 certain circumstances.
628
629
630 -------------------------------------------
631 0.2.7 (2006-12-27) "transparent invariance"
632 -------------------------------------------
633
634 Not many user-visible changes but a fair amount of internal improvements.
635
636
637 - The http sender buffers data if it can not be sent
638 out immediately (because the socket is not writable). This
639 should prevent para_server from shutting down the connection
640 too early on a loaded network.
641 - para_play also prebuffers data if it is told to start at a
642 future time by the --start_time option.
643 - The return of para_recv: It combines para_ortp_recv and
644 para_http_recv. Use the --receiver option to switch between
645 the two. para_recv builds without libortp, but contains
646 only the http receiver in this case.
647 - update to ortp 0.8.1. As this ortp release contains incompatible
648 changes, para_recv-0.2.7 won't link against older ortp libs.
649 - improved ortp timings.
650 - use of gcc-extensions that #define away for non-gcc and
651 gcc < 3.0.
652
653
654 -------------------------------------------
655 0.2.6 (2005-10-29) "recursive compensation"
656 -------------------------------------------
657
658 Transparent session encryption (uses openssl's Alleged RC4 cipher),
659 the internal find command and several other improvements and cleanups.
660
661 - Encrypt the session if encryption is requested by the client
662 (default for para_client 0.2.6). This is backwards
663 compatible, so older clients can still connect to para_server
664 0.2.6. Use the new client option --plain to request an
665 uncrypted session (off by default, must be set to on in
666 order to connect to para_server 0.2.x with 0 <= x <= 5).
667 - para_server uses an internal function to locate audio files
668 rather than calling find(1). The server option
669 --mysql_audio_file_dir replaces --mysql_find_cmd.
670 - documentation update
671 - man pages
672 - header file cleanup
673 - para_client code cleanup
674 - para_gui: faster display of output of display commands
675
676
677 ------------------------------------------
678 0.2.5 (2005-10-13) "aggressive resolution"
679 ------------------------------------------
680
681 This release adds internal senders, i.e. no more external programs are
682 spawned for sending out the audio data. There are two different senders
683 available: The http sender and the ortp sender (former para_send which
684 is no longer needed).
685
686 The new sender code has a plugin-like design so it can be easily
687 extended should there be be any future need for supporting another
688 network streaming protocol. All senders are completely independent of
689 each other. In particular, the http and the ortp sender can operate
690 in parallel.
691
692 - new server command: sender to control senders at runtime.
693 Read the output of "para_server -h" and "para_client help
694 sender" for more information.
695 - para_recv renamed to para_ortp_recv
696 - new executable: para_http_recv, a simple command line
697 http receiver.
698 - major afs/mp3/ogg code simplifications due to internal
699 senders.
700 - ogg timing improvements
701 - fix several minor memory leaks (found by valgrind)
702 - empty stream definitions work again
703 - com_ne(): ignore errors on remove
704 - audiod: fix segfault on server restart
705
706
707 ---------------------------------------
708 0.2.4 (2005-09-21) "toxic anticipation"
709 ---------------------------------------
710
711 Several small improvements, fixes and the new grab command.
712
713 - audiod:
714 - new command: "grab" to grab the output of the stream reader
715 or any filters. Read the output of "para_audioc help grab"
716 for more information.
717 - fix memory leak
718 - code cleanup
719 - audioc: new command line option: --bufsize to specify a
720 buffer size different from the default size 8192.
721 - improved error diagnostics for para_play.
722 - new configure option: --enable-ssldir so search for openssl in
723 non-standard places
724 - sdl_gui: Make it look nice again for 1024x768
725 - server: report total size of memory allocated with sbrk by malloc,
726 new command line option: --announce_time
727
728
729 -----------------------------------------
730 0.2.3 (2005-09-01) "hydrophilic movement"
731 -----------------------------------------
732
733 Two new executables and major feature enhancements.
734
735 - audiod filters: It is now possible to specify arbitrary many
736 (including none) filters for each supported audio
737 format. This can be used e.g. for normalizing volume,
738 transforming or grabbing the audio stream, or for using
739 visualizers. Read the output of "para_audiod -h" for the
740 syntax of the new --filter_cmd option.
741 - new executable: para_play, a tiny alsa player. It
742 can play wave files or raw pcm (16 bit little endian)
743 from stdin.
744 - new executable: para_compress, a dynamic range compressor
745 intended to keep audio output at a consistent volume. Derived
746 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
747 - audiod: New option: --stream_delay. This can be used in
748 a local network to syncronize the audio output of all
749 clients that play the same stream.
750
751
752 ------------------------------------------
753 0.2.2 (2005-08-19) "tangential excitation"
754 ------------------------------------------
755
756 Mostly internal changes in this release, but also some new commands
757 for the mysql database tool.
758
759 - cleanup exec.c, fix para_exec bug
760 - compile time loglevel (log messages below the given level
761 won't be compiled in, which reduces the size of the
762 resulting binaries)
763 - new log macros that shorten the size of the source code.
764 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
765 to send only zeros. With this workaround, para_audioc works
766 again.
767 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
768 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
769 (new entry), "snp" (set numplayed). Read the manual for more
770 information.
771
772
773 ---------------------------------------
774 0.2.1 (2005-08-15) "surreal experience"
775 ---------------------------------------
776
777 Here comes paraslash-0.2.1. It contains a couple of new features and,
778 surprise, only minor bug fixes.
779
780 - kill noisy mp3 debug message
781 - cleanup of the build system
782 - para_server and para_client directly use the crypto routines
783 of the openssl library rather than invoking the openssl command
784 line utitlity
785 - server/audiod: new option --user to switch to the given user
786 when invoked as root. Read the output of "para_server -h" for
787 more information.
788 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
789 status. Default: "para_audioc stat"
790 - sdl_gui: new option --pic_cmd to be used to download the picture.
791 Default: "para_client pic"
792 - audiod: 5 slots ought to be enough for everybody
793 - audiod: new status item: Uptime, kill hup command
794
795
796
797 ------------------------------------------
798 0.2.0 (2005-08-06) "distributed diffusion"
799 ------------------------------------------
800
801 After several month of increased development activity, paraslash-0.2.0
802 has arrived. It contains many new features and is much more
803 self-contained than the old 0.1.x series. Enjoy!
804
805
806 - para_server: fix hang on song change and crash on sighup.
807 Speed up mysql queries. The DIR_LIKE macro is gone.
808 - new executables: para_audiod, the local audio daemon that
809 starts playback (uses SCM_CREDENTIALS socket magic) and
810 para_audioc, the corresponding client.
811 - new executables: para_mp3dec/para_oggdec, two really teensy
812 decoders. para_mp3dec is based on libmad, para_oggdec requires
813 libvorbisfile.
814 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
815 they are now called para_send and para_recv respectively.
816 - documentation updates
817 - para_gui is themable. For now there is the default theme that
818 looks as before and the simple theme: blue and easy.
819 - gui: audio streaming is now handled by audiod. Time display shows
820 playback time rather than streaming time
821 - slider: update to libzmw-0.2.0
822 - para_krell: fix crash on server shutdown
823 - switch from gzip to bzip2
824
825
826 ----------------------------------------
827 0.1.7 (2005-04-18) "melting penetration"
828 ----------------------------------------
829
830 The main change in this release is clearly the oggvorbis rewrite,
831 but there are also lots of smaller changes. If you intend to use both
832 the mp3 and the ogg plugin, it is recommended to use software mixing,
833 e.g. the dmix plugin which is provided by ALSA.
834
835 - new executables: para_ovsend and para_ovrecv for sending/receiving
836 oggvorbis files via rtp. Requires the open rtp library. Get it at
837 http://www.linphone.org/ortp/
838 - rewrite of the ogg_vorbis core code
839 - configure detects libzmw and, if detected, includes
840 para_slider to the list of binaries to be built by make
841 - server stream writers read from their associated fifo rather
842 than from stdin
843 - slider: two new sliders, lastplayed and numplayed
844 - fix nasty double free bug which caused random segfaults in case of
845 mp3 files with invalid header information
846 - gui: new command line option: --stream_timeout=seconds to
847 deactivate a slot if it is idle for that many seconds (default=`5')
848 - diffstats
849
850
851 ---------------------------------------
852 0.1.6 (2005-03-05) "asymptotic balance"
853 ---------------------------------------
854
855 Only little user-visible changes in this release. Mainly bugfixes and
856 core code cleanup. This is probably the most stable version ever if you
857 stick to mp3...
858
859 - fix several memory leaks
860 - rename default name of mysql database from "music" to "paraslash".
861 Use para_server's --mysql_database option if you do not want to
862 rename your old database.
863 - rework ogg vorbis code
864 - make update command work on mysql servers with LOCAL_INFILE
865 disabled
866 - gui: improved stream I/O (slots)
867 - simplified audio format API
868 - para_pob_ogg is gone
869
870 ------------------------------------
871 0.1.5 (2004-12-31) "opaque eternity"
872 ------------------------------------
873
874 Let's slide gently into the new year.
875
876 - new: para_slider (not built automatically, type "make
877 para_slider" to build). A toy for those who always felt that
878 creating stream definitions is difficult. See screenshots,
879 README and FEATURES for more info.
880 - improved signal handling. Fixes server segfault on SIGHUP
881 for linux kernels newer than Aug 24 2004 and makes para_gui
882 race-free.
883 - reload database tool on SIGHUP
884 - improved help message for sl
885 - do not log "broken pipe" messages as errors. They are
886 perfectly ok.
887 - fix wrong error message on permission errors
888
889 -----------------------------------------
890 0.1.4 (2004-12-19) "tunneling transition"
891 -----------------------------------------
892
893 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
894 Hopefully, most of them got wiped out with this release. Some
895 enhancements went also in.
896
897 - improved error diagnostics for all commands
898 - stradd/picadd: overwrite previous contents if entry already
899 exists, rather than returning errors
900 - stradd: use current stream if invoked without args
901 - faster (and hopefully more stable) ogg-vorbis handling
902 - para_krell: reap children to avoid zombie-flooding in case
903 no server is running
904 - si: report also server pid
905 - server: don't busy-loop if dbtool reports only invalid files.
906 - gui: CTRL+C works again, fix stream_read command line option
907 - fix pic_add, hist
908 - fix mysql dbtool startup in case no database exists
909 - many small fixes and cleanups
910
911 ---------------------------------------
912 0.1.3: (2004-12-10) "vanishing inertia"
913 ---------------------------------------
914
915 Starting from this release, the database tools are integrated in the
916 server binary. This decreases server startup time, reduces code size
917 and speeds up database commands. However, the layout of the underlying
918 mysql database changed only slightly and 0.1.3 should be backwards
919 compatible in that respect.
920
921 Visible changes:
922
923 - If mysql is not detected at compile time, or fails to init
924 at runtime, fall back to the dopey database tool which should
925 always work.
926 - para_dbtool and dbtool.conf are gone. All mysql specific
927 options are read from server.conf and are prefixed by 'mysql_'.
928 - new command: cdt (change database tool)
929 - new command line option: dbtool (choose startup database tool)
930 - The name of current stream is now stored in the database,
931 so paraslash remembers its current stream when restarted.
932 - new command: csp (change stream and play)
933 - para_gui also reports current database tool and server uptime
934
935
936 -------------------------------------------
937 0.1.2: (2004-11-28) "spherical fluctuation"
938 -------------------------------------------
939
940 Point release before the big dbtool changes go in.
941
942 - dbtool: rename ca to cam (copy all meta data). It now also
943 copies numplayed and lastplayed time as well as the picture
944 id.
945 - fix endless-loop-bug caused by mp3 files with invalid header
946
947 -----------------------------------------
948 0.1.1: (2004-11-05) "floating atmosphere"
949 -----------------------------------------
950
951 - gkrellm plugin
952 - new dbtool command: mbox. Browse your sound-file collection
953 with your favorite mail reader.
954 - several small fixes
955
956 -------------------------------------
957 0.1.0: (2204-10-22) "rotating cortex"
958 -------------------------------------
959
960 - fix logging bug for loglevel > VERBOSE
961 - fix skip command
962 - correct timings for vbr mp3s
963 - modular audio format support
964 - ogg-vorbis support (experimental)
965 - new server option: autoplay
966
967 -----------------------------------------
968 0.0.99: (2004-07-25) "harmonic deviation"
969 -----------------------------------------
970
971 - rename projectname from icc to paraslash (play, archive, rate
972 and stream large audio sets happily)
973 - paraslash is no longer restricted to one particular audio
974 streaming software
975 - new dbtool commands (stradd, strq, strdel) for easy stream
976 managment w/o configuration file. That obsoletes stream_defs
977 file/config option for dbtool.
978 - picadd accepts jpeg data from stdin
979 - new server commands: ps (select previous stream), sc (song change)
980 - new default pictures for sdl_gui
981 - gui: new key_map option for binding commands and internal
982 functions to arbitrary keys, nice help screen, rip out
983 soundcard/linux specific stuff, avoid noise artefacts while jumping,
984 show silly logo on startup
985 - new executables: para_fade for fading volume, para_dbadm for
986 manipulating attributes
987 - cdb adds _all_ tables to mysql database
988 - revised and beautified documentation
989 - sample dbtool rewritten in C
990 - autoconf
991
992 ---------------------------------------------
993 0.0.98: (2003-12-26) "incremental smoothness"
994 ---------------------------------------------
995
996 - kick icecast in favour of poc. That removes some races and reduces
997 core code considerably.
998 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
999 give finer info on afs' status.
1000 - gui can start decoder (see config options). Further new gui
1001 commands: refresh (^L), jmp (F1-F10)
1002 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
1003 terminates gui. This fixes dead instances consuming memory
1004 continuously.
1005 - new dbtool command: verb for sending verbatim sql queries.
1006 - fix pid_list races (by removing pid_list)
1007 - codename funnies
1008
1009 --------------------
1010 0.0.97: (2003-10-26)
1011 --------------------
1012
1013 - installation prefix now defaults to /usr/local
1014 - new commands for gui: snozze, sleep and reread config
1015 - config file for gui and sdl_gui
1016 - fix problems with filenames containing funny characters
1017 (reported by Thomas Forell)
1018 - improved signal handling for gui, now it rereads conf on SIGHUP
1019 - new dbtool command: cdb (create database)
1020 - switch from argtable to gengetopt
1021 - major code cleanup and speed improvements
1022 - fix several potential buffer overflows
1023 - many small fixes and cleanups
1024
1025 -------------------
1026 0.0.96 (2003-08-30)
1027 -------------------
1028
1029 - easy stream_defs syntax
1030 - sdl_gui can display images associated to the file being played
1031 - Major feature enhancements for icc_gui including dynamic text
1032 placement and the top/bottom window design
1033 - vrfy/clean now also checks for NULL values in attributes as
1034 well as for invalid picture pointers
1035 - fix long outstanding case sensitivity bug
1036 - many small fixes and cleanups
1037
1038 -------------------
1039 0.0.95 (2003-06-29)
1040 -------------------
1041
1042 - sdl gui runs much faster
1043 - new dbtool command: ca (copy attributes)
1044 - count and display number of times the song has been played
1045 - new feature: scoring
1046 - command line options for sdl_gui
1047 - simpler syntax of streams file
1048 - decrease network traffic of stat
1049 - fix zombie bug
1050 - many small fixes and cleanups
1051
1052 -------------------
1053 0.0.94 (2003-05-04)
1054 -------------------
1055
1056 - new server command: ns (next stream)
1057 - new icc_gui command: c (change stream)
1058 - internal mp3info
1059 - stat shows also id3 tag info
1060 - new sdl based gui
1061 - log flodding bug fixed
1062 - many small fixes and cleanups
1063
1064 -------------------
1065 0.0.93 (2003-03-28)
1066 -------------------
1067
