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

991 -------------------
992
993 - easy stream_defs syntax
994 - sdl_gui can display images associated to the file being played
995 - Major feature enhancements for icc_gui including dynamic text
996 placement and the top/bottom window design
997 - vrfy/clean now also checks for NULL values in attributes as
998 well as for invalid picture pointers
999 - fix long outstanding case sensitivity bug
1000 - many small fixes and cleanups
1001
1002 -------------------

1011 - simpler syntax of streams file
1012 - decrease network traffic of stat
1013 - fix zombie bug
1014 - many small fixes and cleanups
1015
1016 -------------------
1017 0.0.94 (2003-05-04)
1018 -------------------
1019
1020 - new server command: ns (next stream)

1022 - internal mp3info
1023 - stat shows also id3 tag info
1024 - new sdl based gui
1025 - log flodding bug fixed
1026 - many small fixes and cleanups
1027
1028 -------------------
1029 0.0.93 (2003-03-28)
1030 -------------------
1031
1032 - colors for icc_gui
1033 - icc_gui sets volume directly (linux only)
1034 - proper locking that fixes some races
1035 - fix security bug that caused commands to be executed even
1036 with unsufficient permissions
1037 - new command: hup to make all servers reread their configuration file
1038 - icecast meta data streaming
1039 - many small fixes and cleanups
