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

974 -------------------
975
976 - easy stream_defs syntax
977 - sdl_gui can display images associated to the file being played
978 - Major feature enhancements for icc_gui including dynamic text
979 placement and the top/bottom window design
980 - vrfy/clean now also checks for NULL values in attributes as
981 well as for invalid picture pointers
982 - fix long outstanding case sensitivity bug
983 - many small fixes and cleanups
984
985 -------------------
986 0.0.95 (2003-06-29)
987 -------------------
988
989 - sdl gui runs much faster
990 - new dbtool command: ca (copy attributes)
991 - count and display number of times the song has been played
992 - new feature: scoring
993 - command line options for sdl_gui
994 - simpler syntax of streams file
995 - decrease network traffic of stat
996 - fix zombie bug
997 - many small fixes and cleanups
998
999 -------------------
1000 0.0.94 (2003-05-04)
1001 -------------------
1002
1003 - new server command: ns (next stream)
1004 - new icc_gui command: c (change stream)
1005 - internal mp3info
1006 - stat shows also id3 tag info
1007 - new sdl based gui
1008 - log flodding bug fixed
1009 - many small fixes and cleanups
1010
1011 -------------------
1012 0.0.93 (2003-03-28)
1013 -------------------
1014
1015 - colors for icc_gui
1016 - icc_gui sets volume directly (linux only)
1017 - proper locking that fixes some races
1018 - fix security bug that caused commands to be executed even
1019 with unsufficient permissions
1020 - new command: hup to make all servers reread their configuration file
1021 - icecast meta data streaming
1022 - many small fixes and cleanups
