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

1026 -------------------
1027
1028 - easy stream_defs syntax
1029 - sdl_gui can display images associated to the file being played
1030 - Major feature enhancements for icc_gui including dynamic text
1031 placement and the top/bottom window design
1032 - vrfy/clean now also checks for NULL values in attributes as
1033 well as for invalid picture pointers
1034 - fix long outstanding case sensitivity bug
1035 - many small fixes and cleanups
1036
1037 -------------------
1038 0.0.95 (2003-06-29)
1039 -------------------
1040
1041 - sdl gui runs much faster
1042 - new dbtool command: ca (copy attributes)
1043 - count and display number of times the song has been played
1044 - new feature: scoring
1045 - command line options for sdl_gui
1046 - simpler syntax of streams file
1047 - decrease network traffic of stat
1048 - fix zombie bug
1049 - many small fixes and cleanups
1050
1051 -------------------
1052 0.0.94 (2003-05-04)
1053 -------------------
1054
1055 - new server command: ns (next stream)
1056 - new icc_gui command: c (change stream)
1057 - internal mp3info
1058 - stat shows also id3 tag info
1059 - new sdl based gui
1060 - log flodding bug fixed
1061 - many small fixes and cleanups
1062
1063 -------------------
1064 0.0.93 (2003-03-28)
1065 -------------------
1066
1067 - colors for icc_gui
