Merge branch 't/t0004_fix'
[paraslash.git] / NEWS
1 -----------------------------------------------
2 0.4.10 (to be announced) "heterogeneous vacuum"
3 -----------------------------------------------
4
5 - The --no_default_filters option of para_filter has been
6 depricated. It still works but has no effect and will be
7 removed in the next version.
8 - Cleanup and consolidation of the various wrappers for
9 write(), writev(), send() and friends.
10 - The obscure error messages on mmap() failures have been
11 replaced by meaningful messages. This affects mainly
12 para_afh.
13 - para_audioc: Cleanups and memory leak fixes.
14 - Test 0004-server no longer fails if para_server is not
15 being built.
16
17 -------------------------------------
18 0.4.9 (2011-12-06) "hybrid causality"
19 -------------------------------------
20
21 Support for another audio format, interactive mode for para_client
22 and para_audiod and many small improvements/fixes all over the place.
23
24 - Support for flac, the free lossless audio codec.
25 - Fix for an endless loop in the mp3 decoder for certain
26 (corrupt) mp3 files.
27 - When executed without specifying a command, para_client
28 and para_audioc start an interactive shell (requires
29 libreadline being installed). The interactive mode offers
30 full tab completion and command line history.
31 - autogen.sh now detects a distcc setup and adjusts the
32 parameter for the -j option of make accordingly.
33 - Shared memory areas are no longer restricted to 64K. We now
34 detect the maximal size of a shared memory area at runtime.
35 - cleanup of the internal uptime API.
36 - para_server prefaults the mmapped audio file to avoid
37 delays on slow media.
38 - A new test for the test-suite that exercises the
39 communication between para_server and para_audiod.
40 - The alsa writer eats up less CPU cycles when configured to
41 use the DMIX plugin.
42 - Simplified and unified receiver code.
43 - Makefile cleanups.
44 - Commands which print a list of matching audio files now
45 emit a meaningful error message if no audio file matched the
46 given pattern(s).
47
48 --------------------------------------
49 0.4.8 (2011-08-19) "nested assignment"
50 --------------------------------------
51
52 Gcrypt support, the overhauled osx writer and regex format specifiers
53 are the highlights of this release.
54
55 - support for libgcrypt as a drop-in replacement for openssl.
56 Run configure --enable-cryptolib=gcrypt to link against
57 libgcrypt. The two crypto implementations are compatible to
58 each other, i.e. a para_client executable linked against
59 gcrypt can connect to para_server linked against libssl
60 and vice versa.
61 - Rewrite of the osx writer (output plugin for Mac OS).
62 - audiod: The format specifier for receivers, filters and
63 writers is now treated as a regular expression. This allows
64 to replace 5 lines in the config file (one for each audio
65 format) by one single line. See the manual for details.
66 - The *.cmdline.[ch] files are no longer contained in the released
67 tarballs. This reduces the size of the tarballs but requires
68 gengetopt to build the tarball.
69 - Compiles cleanly also with llvm/clang.
70 - Corrupt mp3 files are handled more gracefully.
71 - The alsa writer uses poll fds instead of computing timeouts.
72 - Cleanup of the generic writer API.
73 - sched: Optimized zero timeouts.
74 - vss timeout cleanups.
75 - oggdec fixes and improvements.
76
77 --------------------------------------
78 0.4.7 (2011-06-01) "infinite rollback"
79 --------------------------------------
80
81 The new ao writer, support for ssh RSA keys and a couple of other
82 enhancements.
83
84 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
85 platforms through the libao audio library.
86 - Support for RSA keys generated with ssh-keygen.
87 - configure: improved options for ogg/vorbis/speex.
88 - The git version reported by --version always matches HEAD.
89 - The autogen script detects the number of processors and
90 runs a parallel make if possible.
91 - Major cleanup of the crypto API.
92 - Documentation updates.
93
94 ------------------------------------------
95 0.4.6 (2011-03-31) "deterministic entropy"
96 ------------------------------------------
97
98 Lots of ogg/vorbis improvements, the new test suite, enhancements
99 for para_gui and a fair amount of other bug fixes.
100
101 - For DCCP/OGG streams the audio file header is only sent once
102 at the beginning of the stream rather than periodically
103 every five seconds. This reduces network traffic and the
104 FEC group size.
105 - The vorbis comment header is replaced by an empty dummy header
106 before the header is sent over the network. This also results in
107 less network traffic and smaller FEC groups.
108 - The new "test" make target allows to perform some sanity checks prior
109 to installing the package.
110 - ogg timing fixes and performance improvements
111 - Scheduler improvements
112 - Proper exit codes for para_write
113 - para_gui: New option --theme to select a startup theme. Several
114 other improvements and fixes.
115 - aacdec error message cleanups
116 - simplified color error handling
117
118 --------------------------------------------
119 0.4.5 (2010-12-17) "symmetric randomization"
120 --------------------------------------------
121
122 Bug fixes, internal cleanups and variable-sized FEC slices.
123
124 - Contains a fix for an invalid-free-bug in the ogg audio format
125 handler code.
126 - Switching off the DCCP sender works again.
127 - para_audiod handles crashes of para_server more robustly.
128 - Internal scheduler and writer cleanups.
129 - Reduced latency due to variable-sized FEC slices.
130 - Improved documentation and error diagnostics.
131 - The build of para_server is now optional, allowing the build
132 to succeed in case libosl is not installed.
133
134 ------------------------------------------
135 0.4.4 (2010-08-06) "persistent regularity"
136 ------------------------------------------
137
138 Support for yet another audio format, para_write improvements and
139 bug fixes.
140
141 - Support for the speex codec.
142 - Support for sample formats other than 16 bit little endian.
143 - error2.h is now created by a perl script which speeds up configure
144 considerably.
145 - Fix a bug in the aac decoder which could lead to segfaults in
146 para_filter/para_audiod.
147 - Fixes for autoconf-2.66.
148
149 ----------------------------------------
150 0.4.3 (2010-07-05) "imaginary radiation"
151 ----------------------------------------
152
153 Many improvements for the DCCP and the UDP transport, the new user
154 manual and the usual mix of bug fixes and internal improvements.
155
156 - FEC support for the DCCP sender (Gerrit Renker). The new
157 --dccp_max_slice_size, --dccp_data_slices_per_group and
158 --dccp_slices_per_group options can be used to set the FEC
159 parameters for the DCCP transport.
160 - DNS lookups for UDP targets (Gerrit Renker).
161 - The new user manual replaces the README, README.afs, REQUIREMENTS
162 and INSTALL documents.
163 - Fix an end-of-file detection bug in the oggdec filter.
164 - The new nonblock API.
165 - Both options of the oggdec filter have been removed.
166 - New debug mode for the internal scheduler.
167
168 ------------------------------------------
169 0.4.2 (2010-04-23) "associative expansion"
170 ------------------------------------------
171
172 It's been some time since the last release, but finally here is
173 paraslash-0.4.2. The bulk of the changes comes from the new buffer
174 tree API, but there are changes all over the tree. Mainly performance
175 and usability improvements, but also quite some bug fixes.
176
177 - The new buffer tree API.
178 - DCCP: Support for CCID negotiation (Gerrit Renker).
179 - UDP robustness fixes.
180 - The --bufsize option for mp3dec is gone as it no longer makes sense
181 for the new buffer tree API.
182 - Fix audible buffer underruns for wma streams.
183 - The alsa writer no longer prints meaningless underrun durations.
184 - audiod: Defaults work also for udp streams. If no filter is
185 given for an audio format that is received via upd, fecdec is
186 automatically added as the first filter (along with the decoder).
187
188 ---------------------------------------
189 0.4.1 (2009-12-22) "concurrent horizon"
190 ---------------------------------------
191
192 Support for another audio format, minor feature enhancements and lots of bug
193 fixes. All fixes that have been accumulated in the maint branch (in particular
194 those mentionened in the 0.3.6 release notes) appear in this release as well.
195
196 - wma support.
197 - new afh option: --human to activate human-readable output.
198 - new server/audiod option: --log-timing to print timing information.
199 - build system improvements.
200 - source code documentation updates.
201
202 -------------------------------------
203 0.3.6 (2009-12-07) "cubic continuity"
204 -------------------------------------
205
206 Quite a few bugs have been found and fixed since 0.3.5, so here's
207 another 0.3.x release. No new features.
208
209 - Always check return value of malloc().
210 - ogg vorbis/FEC: Do not write garbage after the audio file header.
211 - exit if root privileges could not be dropped.
212 - FEC: Fix computation of extra slices.
213 - oss: Fix check for empty input buffer.
214 - Avoid buffer underruns due to filter chain output buffer constraints.
215 - server: Fix assignment of afs_pid.
216 - Don't panic if the afs database contains unknown audio formats.
217 - http/dccp: Do not send the audio file header twice.
218 - FEC: Timing improvements.
219
220 ----------------------------------------------
221 0.4.0 (2009-11-10) "simultaneous independence"
222 ----------------------------------------------
223
224 Two significant changes which require the new version number: The
225 improved authentication dialog and the fact that the database code
226 has been moved to a library, libosl. To use the new version, you have
227 to generate new RSA keys, see INSTALL for details. A shell script is
228 provided for conversion of the 0.3 database to the new 0.4 format.
229
230 - stronger crypto for client authentication
231 - the database code has been moved to a library
232 - improved status item handling
233 - cleanup of the build system
234 - The "-V" option now also prints the git version
235 - the new parser-friendly listing mode for the ls and stat commands
236 - mandatory rc4 encryption
237 - major audio format handler cleanups
238 - (id3,...) tags are no longer stored as a combined string in the database
239 - new mood methods: artist_matches, title_matches, comment_matches,
240 album_matches, year_maches, year.
241
242 --------------------------------------------
243 0.3.5 (2009-09-21) "symplectic separability"
244 --------------------------------------------
245
246 Full client support for *BSD Unixes, complete re-write of the ogg
247 vorbis audio format handler, various improvements all over the place
248 and the usual mix of bugfixes. This release marks the end of the 0.3
249 series if no serious problems show up.
250
251 - the new oss writer (supported on *BSD and Linux)
252 - rewrite of the ogg vorbis audio format handler. It's
253 recommended to replace the chunk tables of existing ogg
254 vorbis files in the afs database by re-adding these files
255 with "add -f".
256 - support for netmask subsets (Gerrit Renker)
257 - the new prebuffer filter
258 - improved signal handling
259 - variable fec output buffer size
260 - improved FEC timing fixes audible buffer underruns in UDP mode
261 - --log_color actually works
262 - new ls option: -d (print dates as seconds after the epoch)
263 - update to gengetopt 2.22.2
264 - support for RSA keys of size > 512 bits
265 - new option "mixer_channel" for para_fade
266
267 -----------------------------------------
268 0.3.4 (2009-05-07) "elliptic inheritance"
269 -----------------------------------------
270
271 The new udp sender, forward error correction, colored logs and various
272 other improvements. As the udp sender does not depend on any special
273 libraries, it is built unconditionally.
274
275 - The udp sender replaces the ortp sender. The new code uses forward
276 error correction to protect against packet losses. Many thanks to
277 Gerrit Renker for providing ipv6 support.
278 - The default port for udp streaming now defaults to 8000, like
279 for the http and the dccp senders/receivers.
280 - Loglevels are now specified as symbolic names, e.g.
281 "--loglevel info".
282 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
283 - para_server/para_audiod: Color support for log messages.
284 - new options for mp3dec: --ignore-crc, --bufsize
285 - new audiod option: --config-file.
286 - gengetopt cleanups.
287 - Improved help/man pages: The documentation of para_audiod,
288 para_recv, para_filter and para_write now also contains
289 all options of the available receivers/filters/writers. The
290 man page of para_fade contains a description of the different
291 modes of operation.
292 - More source code documentation.
293 - vss timing fixes.
294
295 --------------------------------------------
296 0.3.3 (2008-12-01) "axiomatic perspectivity"
297 --------------------------------------------
298
299 Internal code cleanups, bug fixes, improved tag handling and the new
300 amplification filter.
301
302 - para_server uses the generic scheduling code.
303 - overhaul of the virtual streaming system.
304 - mp3: id3 version 2 support via libid3tag (optional)
305 - ogg: vorbis comment support.
306 - aac meta info support.
307 - mp3 audio format handler cleanups.
308 - new filter: "amp" to amplify the amplitude of the audio stream
309 - new status item/database entry: amplification. It is
310 used by the amp filter to pre-amplify the audio stream.
311 - fix a close-without-open bug in para_write.
312 - fix a bug in com_init() which was introduced in 0.3.2.
313 - better error diagnostics for para_client.
314
315 -----------------------------------------
316 0.3.2 (2008-04-11) "probabilistic parity"
317 -----------------------------------------
318
319 The new para_afh executable, scheduling and documentation improvements.
320
321 - new ls option: -lc (list chunk table)
322 - new executable: para_afh, the stand-alone audio file handler tool
323 - afs commands can send output more than SHMMAX (32MB on Linux). This
324 also reduces the memory usage of commands that produce large amounts
325 of output.
326 - major scheduler and audiod cleanups.
327 - more detailed and much nicer man pages.
328
329 ---------------------------------------
330 0.3.1 (2008-02-23) "liquid interaction"
331 ---------------------------------------
332
333 A mix of cleanups, bug fixes, improvements, and some new features. No
334 significant changes to the new database (osl) code, which is generally
335 a good sign.
336
337 - Share some similar/duplicate code between the http and the
338 dccp sender.
339 - Generic access control lists for paraslash senders.
340 - dccp sender: Access control lists, connection limiting and support
341 for the allow,deny,on,off,help sender commands.
342 - The default dccp port changed from 5001 to 8000 (suggested by
343 Gerrit Renker).
344 - para_server starts even if not all public keys could be loaded.
345 - Audiod performance improvements.
346 - fix a bug in the "off" command of the http sender.
347 - fix some fd and memory leaks.
348 - Update to gengetopt-2.22.
349
350 -------------------------------------
351 0.3.0 (2008-01-12) "solar saturation"
352 -------------------------------------
353
354 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
355
356
357 Usually one might expect lots of new features AND a big increase in size
358 for a major release like this.
359
360 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
361 ever. The decrease in size is mostly due to the removal of some
362 graphical tools (which were only quick hacks anyway). But also the
363 fact that the mysql code is gone cuts down the size a bit.
364
365 Being independent of mysql comes at a cost: The fact that paraslash
366 now contains its own database (the object storage layer, osl) increases
367 the (stripped) binary size of para_server by ~50K on i386.
368
369 - no more restrictions on unique basenames.
370 - independent of mysql: The new self-contained object
371 storage layer (osl) replaces the mysql database.
372 - New executable para_fsck: Check integrity of osl tables.
373 - Lyrics support.
374 - Reliable audio file move/rename detection.
375 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
376 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
377 Solaris (sparc64).
378 - the new osl-based audio file selector (afs) replaces the random,
379 the playlist and the mysql selector of paraslash-0.2.x.
380 - IPv6 support (thanks to Gerrit Renker).
381 - paraslash-0.2.x streams are now called "moods". Writing
382 0.3.x-mood definitions should be both easier and more
383 powerful than writing 0.2.x-stream definitions.
384 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
385 been removed. The world is a better place without them. However,
386 para_gui is still there.
387 - afs tracks audio file selection also in playlist mode.
388 - few easy-to-use afs commands replace the many not-so-easy-to-use
389 mysql commands (and are available also in playlist mode).
390 - Improved error subsystem.
391 - The earth-shaking new logo.
392
393 -----------------------------------------
394 0.2.17 (2007-11-20) "isotropic threshold"
395 -----------------------------------------
396
397 Mainly bugfixes and cleanups in this version which marks the end of
398 the 0.2.x series if no serious bugs show up after the release.
399
400 - mysql_selector: fix a locking bug.
401 - universal chunk queueing.
402 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
403 to Gerrit Renker).
404 - be more carful wrt. signed vs. unsigned argument passing.
405 - cleanup error.h and fix some references to invalid error
406 codes.
407 - update to gengetopt-2.21.
408 - update to ortp-0.13.1.
409 - autoconf: extend checks for headers, library functions and
410 compiler characteristics.
411 - Fix streaming of large mp3 files.
412 - Fix an off-by-one bug in playlist handling.
413
414 --------------------------------------
415 0.2.16 (2007-04-05) "neural discharge"
416 --------------------------------------
417
418 The main change in this release is the major audio format handler
419 cleanup which removes some similar/duplicate code and makes it easier
420 to implement plugins for other audio formats. Of course, the usual mix
421 of other improvements/changes/bugfixes also made it into the release.
422
423 - simplified audio format handlers (most of the handling functions
424 were moved one layer up to the virtual streaming system).
425 - para_server uses mmap to read audio files
426 - repositioning of mp3 streams is much faster, in particular for
427 jumping near the end of large mp3 files.
428 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
429 and AFS_WRITE.
430 - fix a bug in para_filter that caused decoding of aac files
431 to start only after a few seconds.
432 - fix osx_writer hangs
433 - simplified dccp code (thanks to Gerrit Renker)
434 - the compress filter works also on big endian systems (ppc)
435
436 -----------------------------------------
437 0.2.15 (2007-02-16) "inductive resonance"
438 -----------------------------------------
439
440 Minor improvements, more documentation and a bunch of bug fixes.
441
442 - para_server: The server.users file is only read once on server
443 startup rather than for each connection
444 - mp3dec: Fix decoding of corrupt mp3 files
445 - afs (audio file sender) is now called vss (virtual streaming
446 system). Consequently, the permission flags specified in
447 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
448 become VSS_READ and VSS_WRITE respectively.
449 - para_audiod/para_filter: Fix a bug that caused the last chunk
450 of audio data not being written under certain circumstances
451 - audiod: compute the difference of server time and local time
452 correctly
453 - para_server/para_audiod: Fix some memory leaks
454 - documentation improvements
455 - configure.ac: fix checks for para_krell
456 - new man pages
457
458 -------------------------------------------
459 0.2.14 (2006-10-15) "transient singularity"
460 -------------------------------------------
461
462 The only major enhancement of this version is the osx writer which completes
463 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
464 until now for reasons beyond the scope of this changelog entry.
465
466 - new output plugin for Mac Os: the osx writer
467 - rename configure command line options from --enable-xxx-headers to
468 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
469 - configure: new command line options: --with-mad-headers,
470 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
471 - some robustness fixes
472 - dymamic audio format recognition for audiod
473 - para_server: new command line option: --autoplay_delay
474 - para_audiod: new command line option: --clock_diff_count
475
476 ---------------------------------------
477 0.2.13 (2006-07-14) "sonic convolution"
478 ---------------------------------------
479
480 A bunch of new features and core changes.
481
482 - the new paraslash scheduler, short and sweet.
483 - Support for m4a/mp4 files via the new aac audio format
484 handler/filter (requires libfaad).
485 - each writer has its own command line parser, just like
486 para_recv and para_filter.
487 - para_client and para_audioc use the error subsystem
488 - writers are integrated in para_audiod (currently linux-only)
489 - para_client is integrated in para_audiod
490 - random/playlist selector: improved info strings
491 - new audiod commands: tasks, kill
492 - update to libortp-0.10.1
493 - para_fade: wake time defaults to 8 hours from now
494 - update to autoconf-2.60
495
496
497 ------------------------------------------
498 0.2.12 (2006-05-12) "oriented abstraction"
499 ------------------------------------------
500
501 Many user-visible changes in this release and lots of new
502 features:
503
504
505 - the new optional dccp sender/receiver. It uses the datagram
506 congestion control protocol. You'll need a fairly new kernel
507 for this.
508 - paraslash works on Mac OS X (thanks to Gerd Becker)
509 - para_play renamed to para_write
510 - modular output plugin design (writers) for para_write
511 - new file_writer output plugin for para_write
512 - compress filter speed improvements
513 - update to libortp-0.9.1
514 - update to gengetopt-2.17rc
515 - para_client no longer depends on libreadline (as the
516 code for the interactive mode was removed).
517 - gcc-2-95 is no longer a supported compiler. It may still
518 work, but it gets no more testing.
519 - the tarball no longer contains the screenshot images which
520 reduces its size quite a bit.
521 - configure: new command line options: --enable-mysql-headers
522 and --enable-mysql-libs
523
524 ------------------------------------
525 0.2.11 (2006-03-11) "atomic duality"
526 ------------------------------------
527
528 Here it is, the first paraslash release developed with git. There
529 are fairly many user-visible changes in this release. As two out of
530 the three "database tools" of paraslash don't use a database at all,
531 they are now called "audio file selectors" instead.
532
533
534 - the cdt command (change database tool) becomes chs (change
535 selector)
536 - no more colon separators: The syntax of some options of
537 para_audiod and para_filter have changed. Use --help for
538 more info (and some examples).
539 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
540 - switch from cvs to git (should've done that earlier)
541 - the new ipc subsystem
542 - new audio file selector: playlist
543 - para_server: the dopey selector is now called "random",
544 and is the default selector. Use the --selector option to
545 choose another selector at startup, or the chs command to
546 change the selector at runtime.
547 - X86_64 fixes (thanks to Steffen Klassert)
548 - para_play fixes
549
550
551 --------------------------------------
552 0.2.10 (2006-02-17) "cyclic attractor"
553 --------------------------------------
554
555 Huge documentation update, a scrollable window for para_gui, ortp
556 improvements, and of course many small fixes not mentioned here.
557 The diffstat below is rather misleading as most insertions are due
558 to the new source documentation.
559
560 - autoconf cleanup
561 - para_server also uses the new error subsystem
562 - lots of new documentation (UTSL)
563 - gui improvements:
564 - keysyms for cursor keys and for next/previous page keys
565 - scrollable output window
566 - new internal commands: scroll up/down, page up/down
567 - fix color of command output.
568 - ortp: the --chunk_time and --header flags are no longer needed
569 for para_recv/para_audiod as this information is now encoded in
570 each rtp packet sent by para_server.
571
572
573 -------------------------------------------
574 0.2.9 (2006-01-24) "progressive turbulence"
575 -------------------------------------------
576
577 Internal audiod receivers/filters, the new error subsystem and
578 a lot of small improvements.
579
580 - para_recv and para_filter are integrated into the para_audiod
581 binary, i.e. audiod no longer spawns a new process for
582 each receiver/filter. As para_recv and para_filter might be
583 useful as standalone programs, they still get built (linked
584 against the same object files that are also used for audiod).
585 - further ortp timing improvements should reduce the CPU usage
586 of the ortp receiver.
587 - improved audio grabbing. The 'grab' command of para_audiod
588 has its own set of command line options. Read the output of
589 "para_audioc help grab" for more info.
590 - oggdec: configurable input prebuffer size.
591 - the new error subsystem gives better error diagnostics
592 and reduces code size.
593
594
595 -----------------------------------------
596 0.2.8 (2006-01-02) "dynamic accumulation"
597 -----------------------------------------
598
599 The new modular filter design and the para_play-hangs bugfix.
600
601 - new executable: para_filter. It combines para_mp3dec,
602 para_oggdec and para_compress. It also adds a further filter
603 type, wav, that just inserts a wave header at the desired point
604 of the filter chain. All 'piping' is done in-memory (i.e. no
605 read/write operations are used).
606 - para_play: fix a stupid bug that caused it to hang under
607 certain circumstances.
608
609
610 -------------------------------------------
611 0.2.7 (2006-12-27) "transparent invariance"
612 -------------------------------------------
613
614 Not many user-visible changes but a fair amount of internal improvements.
615
616
617 - The http sender buffers data if it can not be sent
618 out immediately (because the socket is not writable). This
619 should prevent para_server from shutting down the connection
620 too early on a loaded network.
621 - para_play also prebuffers data if it is told to start at a
622 future time by the --start_time option.
623 - The return of para_recv: It combines para_ortp_recv and
624 para_http_recv. Use the --receiver option to switch between
625 the two. para_recv builds without libortp, but contains
626 only the http receiver in this case.
627 - update to ortp 0.8.1. As this ortp release contains incompatible
628 changes, para_recv-0.2.7 won't link against older ortp libs.
629 - improved ortp timings.
630 - use of gcc-extensions that #define away for non-gcc and
631 gcc < 3.0.
632
633
634 -------------------------------------------
635 0.2.6 (2005-10-29) "recursive compensation"
636 -------------------------------------------
637
638 Transparent session encryption (uses openssl's Alleged RC4 cipher),
639 the internal find command and several other improvements and cleanups.
640
641 - Encrypt the session if encryption is requested by the client
642 (default for para_client 0.2.6). This is backwards
643 compatible, so older clients can still connect to para_server
644 0.2.6. Use the new client option --plain to request an
645 uncrypted session (off by default, must be set to on in
646 order to connect to para_server 0.2.x with 0 <= x <= 5).
647 - para_server uses an internal function to locate audio files
648 rather than calling find(1). The server option
649 --mysql_audio_file_dir replaces --mysql_find_cmd.
650 - documentation update
651 - man pages
652 - header file cleanup
653 - para_client code cleanup
654 - para_gui: faster display of output of display commands
655
656
657 ------------------------------------------
658 0.2.5 (2005-10-13) "aggressive resolution"
659 ------------------------------------------
660
661 This release adds internal senders, i.e. no more external programs are
662 spawned for sending out the audio data. There are two different senders
663 available: The http sender and the ortp sender (former para_send which
664 is no longer needed).
665
666 The new sender code has a plugin-like design so it can be easily
667 extended should there be be any future need for supporting another
668 network streaming protocol. All senders are completely independent of
669 each other. In particular, the http and the ortp sender can operate
670 in parallel.
671
672 - new server command: sender to control senders at runtime.
673 Read the output of "para_server -h" and "para_client help
674 sender" for more information.
675 - para_recv renamed to para_ortp_recv
676 - new executable: para_http_recv, a simple command line
677 http receiver.
678 - major afs/mp3/ogg code simplifications due to internal
679 senders.
680 - ogg timing improvements
681 - fix several minor memory leaks (found by valgrind)
682 - empty stream definitions work again
683 - com_ne(): ignore errors on remove
684 - audiod: fix segfault on server restart
685
686
687 ---------------------------------------
688 0.2.4 (2005-09-21) "toxic anticipation"
689 ---------------------------------------
690
691 Several small improvements, fixes and the new grab command.
692
693 - audiod:
694 - new command: "grab" to grab the output of the stream reader
695 or any filters. Read the output of "para_audioc help grab"
696 for more information.
697 - fix memory leak
698 - code cleanup
699 - audioc: new command line option: --bufsize to specify a
700 buffer size different from the default size 8192.
701 - improved error diagnostics for para_play.
702 - new configure option: --enable-ssldir so search for openssl in
703 non-standard places
704 - sdl_gui: Make it look nice again for 1024x768
705 - server: report total size of memory allocated with sbrk by malloc,
706 new command line option: --announce_time
707
708
709 -----------------------------------------
710 0.2.3 (2005-09-01) "hydrophilic movement"
711 -----------------------------------------
712
713 Two new executables and major feature enhancements.
714
715 - audiod filters: It is now possible to specify arbitrary many
716 (including none) filters for each supported audio
717 format. This can be used e.g. for normalizing volume,
718 transforming or grabbing the audio stream, or for using
719 visualizers. Read the output of "para_audiod -h" for the
720 syntax of the new --filter_cmd option.
721 - new executable: para_play, a tiny alsa player. It
722 can play wave files or raw pcm (16 bit little endian)
723 from stdin.
724 - new executable: para_compress, a dynamic range compressor
725 intended to keep audio output at a consistent volume. Derived
726 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
727 - audiod: New option: --stream_delay. This can be used in
728 a local network to syncronize the audio output of all
729 clients that play the same stream.
730
731
732 ------------------------------------------
733 0.2.2 (2005-08-19) "tangential excitation"
734 ------------------------------------------
735
736 Mostly internal changes in this release, but also some new commands
737 for the mysql database tool.
738
739 - cleanup exec.c, fix para_exec bug
740 - compile time loglevel (log messages below the given level
741 won't be compiled in, which reduces the size of the
742 resulting binaries)
743 - new log macros that shorten the size of the source code.
744 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
745 to send only zeros. With this workaround, para_audioc works
746 again.
747 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
748 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
749 (new entry), "snp" (set numplayed). Read the manual for more
750 information.
751
752
753 ---------------------------------------
754 0.2.1 (2005-08-15) "surreal experience"
755 ---------------------------------------
756
757 Here comes paraslash-0.2.1. It contains a couple of new features and,
758 surprise, only minor bug fixes.
759
760 - kill noisy mp3 debug message
761 - cleanup of the build system
762 - para_server and para_client directly use the crypto routines
763 of the openssl library rather than invoking the openssl command
764 line utitlity
765 - server/audiod: new option --user to switch to the given user
766 when invoked as root. Read the output of "para_server -h" for
767 more information.
768 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
769 status. Default: "para_audioc stat"
770 - sdl_gui: new option --pic_cmd to be used to download the picture.
771 Default: "para_client pic"
772 - audiod: 5 slots ought to be enough for everybody
773 - audiod: new status item: Uptime, kill hup command
774
775
776
777 ------------------------------------------
778 0.2.0 (2005-08-06) "distributed diffusion"
779 ------------------------------------------
780
781 After several month of increased development activity, paraslash-0.2.0
782 has arrived. It contains many new features and is much more
783 self-contained than the old 0.1.x series. Enjoy!
784
785
786 - para_server: fix hang on song change and crash on sighup.
787 Speed up mysql queries. The DIR_LIKE macro is gone.
788 - new executables: para_audiod, the local audio daemon that
789 starts playback (uses SCM_CREDENTIALS socket magic) and
790 para_audioc, the corresponding client.
791 - new executables: para_mp3dec/para_oggdec, two really teensy
792 decoders. para_mp3dec is based on libmad, para_oggdec requires
793 libvorbisfile.
794 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
795 they are now called para_send and para_recv respectively.
796 - documentation updates
797 - para_gui is themable. For now there is the default theme that
798 looks as before and the simple theme: blue and easy.
799 - gui: audio streaming is now handled by audiod. Time display shows
800 playback time rather than streaming time
801 - slider: update to libzmw-0.2.0
802 - para_krell: fix crash on server shutdown
803 - switch from gzip to bzip2
804
805
806 ----------------------------------------
807 0.1.7 (2005-04-18) "melting penetration"
808 ----------------------------------------
809
810 The main change in this release is clearly the oggvorbis rewrite,
811 but there are also lots of smaller changes. If you intend to use both
812 the mp3 and the ogg plugin, it is recommended to use software mixing,
813 e.g. the dmix plugin which is provided by ALSA.
814
815 - new executables: para_ovsend and para_ovrecv for sending/receiving
816 oggvorbis files via rtp. Requires the open rtp library. Get it at
817 http://www.linphone.org/ortp/
818 - rewrite of the ogg_vorbis core code
819 - configure detects libzmw and, if detected, includes
820 para_slider to the list of binaries to be built by make
821 - server stream writers read from their associated fifo rather
822 than from stdin
823 - slider: two new sliders, lastplayed and numplayed
824 - fix nasty double free bug which caused random segfaults in case of
825 mp3 files with invalid header information
826 - gui: new command line option: --stream_timeout=seconds to
827 deactivate a slot if it is idle for that many seconds (default=`5')
828 - diffstats
829
830
831 ---------------------------------------
832 0.1.6 (2005-03-05) "asymptotic balance"
833 ---------------------------------------
834
835 Only little user-visible changes in this release. Mainly bugfixes and
836 core code cleanup. This is probably the most stable version ever if you
837 stick to mp3...
838
839 - fix several memory leaks
840 - rename default name of mysql database from "music" to "paraslash".
841 Use para_server's --mysql_database option if you do not want to
842 rename your old database.
843 - rework ogg vorbis code
844 - make update command work on mysql servers with LOCAL_INFILE
845 disabled
846 - gui: improved stream I/O (slots)
847 - simplified audio format API
848 - para_pob_ogg is gone
849
850 ------------------------------------
851 0.1.5 (2004-12-31) "opaque eternity"
852 ------------------------------------
853
854 Let's slide gently into the new year.
855
856 - new: para_slider (not built automatically, type "make
857 para_slider" to build). A toy for those who always felt that
858 creating stream definitions is difficult. See screenshots,
859 README and FEATURES for more info.
860 - improved signal handling. Fixes server segfault on SIGHUP
861 for linux kernels newer than Aug 24 2004 and makes para_gui
862 race-free.
863 - reload database tool on SIGHUP
864 - improved help message for sl
865 - do not log "broken pipe" messages as errors. They are
866 perfectly ok.
867 - fix wrong error message on permission errors
868
869 -----------------------------------------
870 0.1.4 (2004-12-19) "tunneling transition"
871 -----------------------------------------
872
873 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
874 Hopefully, most of them got wiped out with this release. Some
875 enhancements went also in.
876
877 - improved error diagnostics for all commands
878 - stradd/picadd: overwrite previous contents if entry already
879 exists, rather than returning errors
880 - stradd: use current stream if invoked without args
881 - faster (and hopefully more stable) ogg-vorbis handling
882 - para_krell: reap children to avoid zombie-flooding in case
883 no server is running
884 - si: report also server pid
885 - server: don't busy-loop if dbtool reports only invalid files.
886 - gui: CTRL+C works again, fix stream_read command line option
887 - fix pic_add, hist
888 - fix mysql dbtool startup in case no database exists
889 - many small fixes and cleanups
890
891 ---------------------------------------
892 0.1.3: (2004-12-10) "vanishing inertia"
893 ---------------------------------------
894
895 Starting from this release, the database tools are integrated in the
896 server binary. This decreases server startup time, reduces code size
897 and speeds up database commands. However, the layout of the underlying
898 mysql database changed only slightly and 0.1.3 should be backwards
899 compatible in that respect.
900
901 Visible changes:
902
903 - If mysql is not detected at compile time, or fails to init
904 at runtime, fall back to the dopey database tool which should
905 always work.
906 - para_dbtool and dbtool.conf are gone. All mysql specific
907 options are read from server.conf and are prefixed by 'mysql_'.
908 - new command: cdt (change database tool)
909 - new command line option: dbtool (choose startup database tool)
910 - The name of current stream is now stored in the database,
911 so paraslash remembers its current stream when restarted.
912 - new command: csp (change stream and play)
913 - para_gui also reports current database tool and server uptime
914
915
916 -------------------------------------------
917 0.1.2: (2004-11-28) "spherical fluctuation"
918 -------------------------------------------
919
920 Point release before the big dbtool changes go in.
921
922 - dbtool: rename ca to cam (copy all meta data). It now also
923 copies numplayed and lastplayed time as well as the picture
924 id.
925 - fix endless-loop-bug caused by mp3 files with invalid header
926
927 -----------------------------------------
928 0.1.1: (2004-11-05) "floating atmosphere"
929 -----------------------------------------
930
931 - gkrellm plugin
932 - new dbtool command: mbox. Browse your sound-file collection
933 with your favorite mail reader.
934 - several small fixes
935
936 -------------------------------------
937 0.1.0: (2204-10-22) "rotating cortex"
938 -------------------------------------
939
940 - fix logging bug for loglevel > VERBOSE
941 - fix skip command
942 - correct timings for vbr mp3s
943 - modular audio format support
944 - ogg-vorbis support (experimental)
945 - new server option: autoplay
946
947 -----------------------------------------
948 0.0.99: (2004-07-25) "harmonic deviation"
949 -----------------------------------------
950
951 - rename projectname from icc to paraslash (play, archive, rate
952 and stream large audio sets happily)
953 - paraslash is no longer restricted to one particular audio
954 streaming software
955 - new dbtool commands (stradd, strq, strdel) for easy stream
956 managment w/o configuration file. That obsoletes stream_defs
957 file/config option for dbtool.
958 - picadd accepts jpeg data from stdin
959 - new server commands: ps (select previous stream), sc (song change)
960 - new default pictures for sdl_gui
961 - gui: new key_map option for binding commands and internal
962 functions to arbitrary keys, nice help screen, rip out
963 soundcard/linux specific stuff, avoid noise artefacts while jumping,
964 show silly logo on startup
965 - new executables: para_fade for fading volume, para_dbadm for
966 manipulating attributes
967 - cdb adds _all_ tables to mysql database
968 - revised and beautified documentation
969 - sample dbtool rewritten in C
970 - autoconf
971
972 ---------------------------------------------
973 0.0.98: (2003-12-26) "incremental smoothness"
974 ---------------------------------------------
975
976 - kick icecast in favour of poc. That removes some races and reduces
977 core code considerably.
978 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
979 give finer info on afs' status.
980 - gui can start decoder (see config options). Further new gui
981 commands: refresh (^L), jmp (F1-F10)
982 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
983 terminates gui. This fixes dead instances consuming memory
984 continuously.
985 - new dbtool command: verb for sending verbatim sql queries.
986 - fix pid_list races (by removing pid_list)
987 - codename funnies
988
989 --------------------
990 0.0.97: (2003-10-26)
991 --------------------
992
993 - installation prefix now defaults to /usr/local
994 - new commands for gui: snozze, sleep and reread config
995 - config file for gui and sdl_gui
996 - fix problems with filenames containing funny characters
997 (reported by Thomas Forell)
998 - improved signal handling for gui, now it rereads conf on SIGHUP
999 - new dbtool command: cdb (create database)
1000 - switch from argtable to gengetopt
1001 - major code cleanup and speed improvements
1002 - fix several potential buffer overflows

1014 well as for invalid picture pointers
1015 - fix long outstanding case sensitivity bug
1016 - many small fixes and cleanups
1017
1018 -------------------

1024 - count and display number of times the song has been played
1025 - new feature: scoring
1026 - command line options for sdl_gui
1027 - simpler syntax of streams file
1028 - decrease network traffic of stat
1029 - fix zombie bug
1030 - many small fixes and cleanups
1031
1032 -------------------
1033 0.0.94 (2003-05-04)
1034 -------------------
1035

1043
1044 -------------------
1045 0.0.93 (2003-03-28)
1046 -------------------
1047
1048 - colors for icc_gui
1049 - icc_gui sets volume directly (linux only)
1050 - proper locking that fixes some races
1051 - fix security bug that caused commands to be executed even
1052 with unsufficient permissions
1053 - new command: hup to make all servers reread their configuration file
1054 - icecast meta data streaming
1055 - many small fixes and cleanups
