paraslash 0.4.14
[paraslash.git] / NEWS
1 -------------------------------------------
2 0.4.14 (2016-12-31) "branching oscillation"
3 -------------------------------------------
4
5 Many fixes for nasty bugs have accumulated over the years since 0.4.13
6 was released in 2013. This release contains all of them. It is the
7 last v0.4.x release, so v0.4.x is now end of life. The maint branch
8 of the git repository has been forwarded to v0.5.7 and will start to
9 receive important fixes for 0.5.x, which is now in maintenance mode.
10
11 - Fix for the "double encryption bug" with gcrypt, which caused
12 garbage to be sent to stat clients.
13 - The "prev" command of para_play now works as expected.
14 - Invalid parameters for the begin and end chunk no longer cause
15 the afh receiver of para_recv to segfault.
16 - A fix for an assertion that triggered in the FEC slice setup code.
17 - Closing the terminal with a running para_gui causes the process to
18 die, rather than using 100% of CPU time.
19 - para_gui no longer shows stale information about the previous
20 audio file.
21 - A fix for a bug in the fec decoder which caused aborts if the buffer
22 pool filled up.
23 - The assertion in the buffer tree code no longer triggers.
24 - The "afs_event: table moods, event 0: key already exists in rbtree"
25 error no longer occurs on attribute changes.
26 - A NULL pointer dereference in com_sender() has been fixed.
27 - The -i option of lsatt works as advertised.
28 - Various fixes for the build system.
29
30 --------------------------------------
31 0.4.13 (2013-07-29) "spectral gravity"
32 --------------------------------------
33
34 One more 0.4.x release before the API-breaking changes for 0.5.0 go
35 in. The main features of this release are the ogg/opus audio format,
36 and UTF-8 support, but it includes also tons of other improvements
37 and fixes all over the place.
38
39 - New audio format: ogg/opus.
40 - UTF8 support for para_gui and the mp3 audio format handler.
41 - Scheduler improvements and fixes.
42 - The obsolete gettimeofday() function has been replaced
43 by clock_gettime() on systems which support it.
44 - Speed and usability improvements for para_gui.
45 - para_client now restores the fd flags of stdin and stdout
46 on shutdown.
47 - Improved manual pages.
48 - Consistent version strings for all executables.
49 - Reduced dependencies on generated files result in fewer
50 recompilations on changes.
51 - Performance improvements for the compress filter.
52 - Improved downloads web page.
53
54 -----------------------------------------
55 0.4.12 (2012-12-20) "volatile relativity"
56 -----------------------------------------
57
58 The new command line player, the resample filter, ALSA support for
59 para_fade, and the improved build system are the highlights of this
60 release which probably marks the end of the 0.4.x series.
61
62 - The afh receiver and the para_play executable.
63 - The resample filter: A sample rate converter based on
64 libsamplerate.
65 - The "versions" directory has been removed from the master
66 branch. The tarballs of the old releases are now available
67 in the new "releases" branch.
68 - Overhaul of the build system: All generated files are now
69 written to the "build" directory.
70 - The modular mixer API and the alsa mixer.
71 - Minor fixes for the osx writer.
72
73 --------------------------------------
74 0.4.11 (2012-07-20) "mutual diversity"
75 --------------------------------------
76
77 The major feature in this release is the new sideband API for
78 client-server communication. This API will be used exclusively starting
79 with 0.5.0, which breaks backward compatibility but allows to get rid
80 of quite some compatibility code. Other noteworthy changes include
81 decoder latency improvements and a long-standing bug fix for the
82 ALSA writer.
83
84 - Sideband connections: If both para_server and para_client
85 support this feature, data is sent as a multiplexed stream.
86 - The --no_default_filters option of para_filter has been
87 removed.
88 - Several fixes and latency improvements to various decoders.
89 - The ALSA writer now limits the prebuffer time to 500ms.
90 - Documentation improvements.
91 - Overhaul of the command_util.sh script.
92 - Fixes for some minor problems found by the clang analyzer.
93 - Compiles (almost) without warnings on gcc-3.
94 - Robustness improvements of the buffer tree code.
95
96 ------------------------------------------
97 0.4.10 (2012-03-30) "heterogeneous vacuum"
98 ------------------------------------------
99
100 Nothing earth-shaking in this release, but quite a few usability
101 improvements and the usual mix of cleanups and fixes.
102
103 - The --no_default_filters option of para_filter has been
104 deprecated. It still works but has no effect and will be
105 removed in the next version.
106 - para_gui now prints also the stderr output of the executing
107 command in the bottom window.
108 - Cleanup and consolidation of the various wrappers for
109 write(), writev(), send() and friends.
110 - The obscure error messages on mmap() failures have been
111 replaced by meaningful messages. This affects mainly
112 para_afh.
113 - para_audioc: Cleanups and memory leak fixes.
114 - Test 0004-server no longer fails if para_server is not
115 being built.
116 - New configure options: --with-id3tag-{headers,libs}.
117
118 -------------------------------------
119 0.4.9 (2011-12-06) "hybrid causality"
120 -------------------------------------
121
122 Support for another audio format, interactive mode for para_client
123 and para_audiod and many small improvements/fixes all over the place.
124
125 - Support for flac, the free lossless audio codec.
126 - Fix for an endless loop in the mp3 decoder for certain
127 (corrupt) mp3 files.
128 - When executed without specifying a command, para_client
129 and para_audioc start an interactive shell (requires
130 libreadline being installed). The interactive mode offers
131 full tab completion and command line history.
132 - autogen.sh now detects a distcc setup and adjusts the
133 parameter for the -j option of make accordingly.
134 - Shared memory areas are no longer restricted to 64K. We now
135 detect the maximal size of a shared memory area at runtime.
136 - cleanup of the internal uptime API.
137 - para_server prefaults the mmapped audio file to avoid
138 delays on slow media.
139 - A new test for the test-suite that exercises the
140 communication between para_server and para_audiod.
141 - The alsa writer eats up less CPU cycles when configured to
142 use the DMIX plugin.
143 - Simplified and unified receiver code.
144 - Makefile cleanups.
145 - Commands which print a list of matching audio files now
146 emit a meaningful error message if no audio file matched the
147 given pattern(s).
148
149 --------------------------------------
150 0.4.8 (2011-08-19) "nested assignment"
151 --------------------------------------
152
153 Gcrypt support, the overhauled osx writer and regex format specifiers
154 are the highlights of this release.
155
156 - support for libgcrypt as a drop-in replacement for openssl.
157 Run configure --enable-cryptolib=gcrypt to link against
158 libgcrypt. The two crypto implementations are compatible to
159 each other, i.e. a para_client executable linked against
160 gcrypt can connect to para_server linked against libssl
161 and vice versa.
162 - Rewrite of the osx writer (output plugin for Mac OS).
163 - audiod: The format specifier for receivers, filters and
164 writers is now treated as a regular expression. This allows
165 to replace 5 lines in the config file (one for each audio
166 format) by one single line. See the manual for details.
167 - The *.cmdline.[ch] files are no longer contained in the released
168 tarballs. This reduces the size of the tarballs but requires
169 gengetopt to build the tarball.
170 - Compiles cleanly also with llvm/clang.
171 - Corrupt mp3 files are handled more gracefully.
172 - The alsa writer uses poll fds instead of computing timeouts.
173 - Cleanup of the generic writer API.
174 - sched: Optimized zero timeouts.
175 - vss timeout cleanups.
176 - oggdec fixes and improvements.
177
178 --------------------------------------
179 0.4.7 (2011-06-01) "infinite rollback"
180 --------------------------------------
181
182 The new ao writer, support for ssh RSA keys and a couple of other
183 enhancements.
184
185 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
186 platforms through the libao audio library.
187 - Support for RSA keys generated with ssh-keygen.
188 - configure: improved options for ogg/vorbis/speex.
189 - The git version reported by --version always matches HEAD.
190 - The autogen script detects the number of processors and
191 runs a parallel make if possible.
192 - Major cleanup of the crypto API.
193 - Documentation updates.
194
195 ------------------------------------------
196 0.4.6 (2011-03-31) "deterministic entropy"
197 ------------------------------------------
198
199 Lots of ogg/vorbis improvements, the new test suite, enhancements
200 for para_gui and a fair amount of other bug fixes.
201
202 - For DCCP/OGG streams the audio file header is only sent once
203 at the beginning of the stream rather than periodically
204 every five seconds. This reduces network traffic and the
205 FEC group size.
206 - The vorbis comment header is replaced by an empty dummy header
207 before the header is sent over the network. This also results in
208 less network traffic and smaller FEC groups.
209 - The new "test" make target allows to perform some sanity checks prior
210 to installing the package.
211 - ogg timing fixes and performance improvements
212 - Scheduler improvements
213 - Proper exit codes for para_write
214 - para_gui: New option --theme to select a startup theme. Several
215 other improvements and fixes.
216 - aacdec error message cleanups
217 - simplified color error handling
218
219 --------------------------------------------
220 0.4.5 (2010-12-17) "symmetric randomization"
221 --------------------------------------------
222
223 Bug fixes, internal cleanups and variable-sized FEC slices.
224
225 - Contains a fix for an invalid-free-bug in the ogg audio format
226 handler code.
227 - Switching off the DCCP sender works again.
228 - para_audiod handles crashes of para_server more robustly.
229 - Internal scheduler and writer cleanups.
230 - Reduced latency due to variable-sized FEC slices.
231 - Improved documentation and error diagnostics.
232 - The build of para_server is now optional, allowing the build
233 to succeed in case libosl is not installed.
234
235 ------------------------------------------
236 0.4.4 (2010-08-06) "persistent regularity"
237 ------------------------------------------
238
239 Support for yet another audio format, para_write improvements and
240 bug fixes.
241
242 - Support for the speex codec.
243 - Support for sample formats other than 16 bit little endian.
244 - error2.h is now created by a perl script which speeds up configure
245 considerably.
246 - Fix a bug in the aac decoder which could lead to segfaults in
247 para_filter/para_audiod.
248 - Fixes for autoconf-2.66.
249
250 ----------------------------------------
251 0.4.3 (2010-07-05) "imaginary radiation"
252 ----------------------------------------
253
254 Many improvements for the DCCP and the UDP transport, the new user
255 manual and the usual mix of bug fixes and internal improvements.
256
257 - FEC support for the DCCP sender (Gerrit Renker). The new
258 --dccp_max_slice_size, --dccp_data_slices_per_group and
259 --dccp_slices_per_group options can be used to set the FEC
260 parameters for the DCCP transport.
261 - DNS lookups for UDP targets (Gerrit Renker).
262 - The new user manual replaces the README, README.afs, REQUIREMENTS
263 and INSTALL documents.
264 - Fix an end-of-file detection bug in the oggdec filter.
265 - The new nonblock API.
266 - Both options of the oggdec filter have been removed.
267 - New debug mode for the internal scheduler.
268
269 ------------------------------------------
270 0.4.2 (2010-04-23) "associative expansion"
271 ------------------------------------------
272
273 It's been some time since the last release, but finally here is
274 paraslash-0.4.2. The bulk of the changes comes from the new buffer
275 tree API, but there are changes all over the tree. Mainly performance
276 and usability improvements, but also quite some bug fixes.
277
278 - The new buffer tree API.
279 - DCCP: Support for CCID negotiation (Gerrit Renker).
280 - UDP robustness fixes.
281 - The --bufsize option for mp3dec is gone as it no longer makes sense
282 for the new buffer tree API.
283 - Fix audible buffer underruns for wma streams.
284 - The alsa writer no longer prints meaningless underrun durations.
285 - audiod: Defaults work also for udp streams. If no filter is
286 given for an audio format that is received via upd, fecdec is
287 automatically added as the first filter (along with the decoder).
288
289 ---------------------------------------
290 0.4.1 (2009-12-22) "concurrent horizon"
291 ---------------------------------------
292
293 Support for another audio format, minor feature enhancements and lots of bug
294 fixes. All fixes that have been accumulated in the maint branch (in particular
295 those mentionened in the 0.3.6 release notes) appear in this release as well.
296
297 - wma support.
298 - new afh option: --human to activate human-readable output.
299 - new server/audiod option: --log-timing to print timing information.
300 - build system improvements.
301 - source code documentation updates.
302
303 -------------------------------------
304 0.3.6 (2009-12-07) "cubic continuity"
305 -------------------------------------
306
307 Quite a few bugs have been found and fixed since 0.3.5, so here's
308 another 0.3.x release. No new features.
309
310 - Always check return value of malloc().
311 - ogg vorbis/FEC: Do not write garbage after the audio file header.
312 - exit if root privileges could not be dropped.
313 - FEC: Fix computation of extra slices.
314 - oss: Fix check for empty input buffer.
315 - Avoid buffer underruns due to filter chain output buffer constraints.
316 - server: Fix assignment of afs_pid.
317 - Don't panic if the afs database contains unknown audio formats.
318 - http/dccp: Do not send the audio file header twice.
319 - FEC: Timing improvements.
320
321 ----------------------------------------------
322 0.4.0 (2009-11-10) "simultaneous independence"
323 ----------------------------------------------
324
325 Two significant changes which require the new version number: The
326 improved authentication dialog and the fact that the database code
327 has been moved to a library, libosl. To use the new version, you have
328 to generate new RSA keys, see INSTALL for details. A shell script is
329 provided for conversion of the 0.3 database to the new 0.4 format.
330
331 - stronger crypto for client authentication
332 - the database code has been moved to a library
333 - improved status item handling
334 - cleanup of the build system
335 - The "-V" option now also prints the git version
336 - the new parser-friendly listing mode for the ls and stat commands
337 - mandatory rc4 encryption
338 - major audio format handler cleanups
339 - (id3,...) tags are no longer stored as a combined string in the database
340 - new mood methods: artist_matches, title_matches, comment_matches,
341 album_matches, year_maches, year.
342
343 --------------------------------------------
344 0.3.5 (2009-09-21) "symplectic separability"
345 --------------------------------------------
346
347 Full client support for *BSD Unixes, complete re-write of the ogg
348 vorbis audio format handler, various improvements all over the place
349 and the usual mix of bugfixes. This release marks the end of the 0.3
350 series if no serious problems show up.
351
352 - the new oss writer (supported on *BSD and Linux)
353 - rewrite of the ogg vorbis audio format handler. It's
354 recommended to replace the chunk tables of existing ogg
355 vorbis files in the afs database by re-adding these files
356 with "add -f".
357 - support for netmask subsets (Gerrit Renker)
358 - the new prebuffer filter
359 - improved signal handling
360 - variable fec output buffer size
361 - improved FEC timing fixes audible buffer underruns in UDP mode
362 - --log_color actually works
363 - new ls option: -d (print dates as seconds after the epoch)
364 - update to gengetopt 2.22.2
365 - support for RSA keys of size > 512 bits
366 - new option "mixer_channel" for para_fade
367
368 -----------------------------------------
369 0.3.4 (2009-05-07) "elliptic inheritance"
370 -----------------------------------------
371
372 The new udp sender, forward error correction, colored logs and various
373 other improvements. As the udp sender does not depend on any special
374 libraries, it is built unconditionally.
375
376 - The udp sender replaces the ortp sender. The new code uses forward
377 error correction to protect against packet losses. Many thanks to
378 Gerrit Renker for providing ipv6 support.
379 - The default port for udp streaming now defaults to 8000, like
380 for the http and the dccp senders/receivers.
381 - Loglevels are now specified as symbolic names, e.g.
382 "--loglevel info".
383 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
384 - para_server/para_audiod: Color support for log messages.
385 - new options for mp3dec: --ignore-crc, --bufsize
386 - new audiod option: --config-file.
387 - gengetopt cleanups.
388 - Improved help/man pages: The documentation of para_audiod,
389 para_recv, para_filter and para_write now also contains
390 all options of the available receivers/filters/writers. The
391 man page of para_fade contains a description of the different
392 modes of operation.
393 - More source code documentation.
394 - vss timing fixes.
395
396 --------------------------------------------
397 0.3.3 (2008-12-01) "axiomatic perspectivity"
398 --------------------------------------------
399
400 Internal code cleanups, bug fixes, improved tag handling and the new
401 amplification filter.
402
403 - para_server uses the generic scheduling code.
404 - overhaul of the virtual streaming system.
405 - mp3: id3 version 2 support via libid3tag (optional)
406 - ogg: vorbis comment support.
407 - aac meta info support.
408 - mp3 audio format handler cleanups.
409 - new filter: "amp" to amplify the amplitude of the audio stream
410 - new status item/database entry: amplification. It is
411 used by the amp filter to pre-amplify the audio stream.
412 - fix a close-without-open bug in para_write.
413 - fix a bug in com_init() which was introduced in 0.3.2.
414 - better error diagnostics for para_client.
415
416 -----------------------------------------
417 0.3.2 (2008-04-11) "probabilistic parity"
418 -----------------------------------------
419
420 The new para_afh executable, scheduling and documentation improvements.
421
422 - new ls option: -lc (list chunk table)
423 - new executable: para_afh, the stand-alone audio file handler tool
424 - afs commands can send output more than SHMMAX (32MB on Linux). This
425 also reduces the memory usage of commands that produce large amounts
426 of output.
427 - major scheduler and audiod cleanups.
428 - more detailed and much nicer man pages.
429
430 ---------------------------------------
431 0.3.1 (2008-02-23) "liquid interaction"
432 ---------------------------------------
433
434 A mix of cleanups, bug fixes, improvements, and some new features. No
435 significant changes to the new database (osl) code, which is generally
436 a good sign.
437
438 - Share some similar/duplicate code between the http and the
439 dccp sender.
440 - Generic access control lists for paraslash senders.
441 - dccp sender: Access control lists, connection limiting and support
442 for the allow,deny,on,off,help sender commands.
443 - The default dccp port changed from 5001 to 8000 (suggested by
444 Gerrit Renker).
445 - para_server starts even if not all public keys could be loaded.
446 - Audiod performance improvements.
447 - fix a bug in the "off" command of the http sender.
448 - fix some fd and memory leaks.
449 - Update to gengetopt-2.22.
450
451 -------------------------------------
452 0.3.0 (2008-01-12) "solar saturation"
453 -------------------------------------
454
455 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
456
457
458 Usually one might expect lots of new features AND a big increase in size
459 for a major release like this.
460
461 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
462 ever. The decrease in size is mostly due to the removal of some
463 graphical tools (which were only quick hacks anyway). But also the
464 fact that the mysql code is gone cuts down the size a bit.
465
466 Being independent of mysql comes at a cost: The fact that paraslash
467 now contains its own database (the object storage layer, osl) increases
468 the (stripped) binary size of para_server by ~50K on i386.
469
470 - no more restrictions on unique basenames.
471 - independent of mysql: The new self-contained object
472 storage layer (osl) replaces the mysql database.
473 - New executable para_fsck: Check integrity of osl tables.
474 - Lyrics support.
475 - Reliable audio file move/rename detection.
476 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
477 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
478 Solaris (sparc64).
479 - the new osl-based audio file selector (afs) replaces the random,
480 the playlist and the mysql selector of paraslash-0.2.x.
481 - IPv6 support (thanks to Gerrit Renker).
482 - paraslash-0.2.x streams are now called "moods". Writing
483 0.3.x-mood definitions should be both easier and more
484 powerful than writing 0.2.x-stream definitions.
485 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
486 been removed. The world is a better place without them. However,
487 para_gui is still there.
488 - afs tracks audio file selection also in playlist mode.
489 - few easy-to-use afs commands replace the many not-so-easy-to-use
490 mysql commands (and are available also in playlist mode).
491 - Improved error subsystem.
492 - The earth-shaking new logo.
493
494 -----------------------------------------
495 0.2.17 (2007-11-20) "isotropic threshold"
496 -----------------------------------------
497
498 Mainly bugfixes and cleanups in this version which marks the end of
499 the 0.2.x series if no serious bugs show up after the release.
500
501 - mysql_selector: fix a locking bug.
502 - universal chunk queueing.
503 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
504 to Gerrit Renker).
505 - be more carful wrt. signed vs. unsigned argument passing.
506 - cleanup error.h and fix some references to invalid error
507 codes.
508 - update to gengetopt-2.21.
509 - update to ortp-0.13.1.
510 - autoconf: extend checks for headers, library functions and
511 compiler characteristics.
512 - Fix streaming of large mp3 files.
513 - Fix an off-by-one bug in playlist handling.
514
515 --------------------------------------
516 0.2.16 (2007-04-05) "neural discharge"
517 --------------------------------------
518
519 The main change in this release is the major audio format handler
520 cleanup which removes some similar/duplicate code and makes it easier
521 to implement plugins for other audio formats. Of course, the usual mix
522 of other improvements/changes/bugfixes also made it into the release.
523
524 - simplified audio format handlers (most of the handling functions
525 were moved one layer up to the virtual streaming system).
526 - para_server uses mmap to read audio files
527 - repositioning of mp3 streams is much faster, in particular for
528 jumping near the end of large mp3 files.
529 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
530 and AFS_WRITE.
531 - fix a bug in para_filter that caused decoding of aac files
532 to start only after a few seconds.
533 - fix osx_writer hangs
534 - simplified dccp code (thanks to Gerrit Renker)
535 - the compress filter works also on big endian systems (ppc)
536
537 -----------------------------------------
538 0.2.15 (2007-02-16) "inductive resonance"
539 -----------------------------------------
540
541 Minor improvements, more documentation and a bunch of bug fixes.
542
543 - para_server: The server.users file is only read once on server
544 startup rather than for each connection
545 - mp3dec: Fix decoding of corrupt mp3 files
546 - afs (audio file sender) is now called vss (virtual streaming
547 system). Consequently, the permission flags specified in
548 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
549 become VSS_READ and VSS_WRITE respectively.
550 - para_audiod/para_filter: Fix a bug that caused the last chunk
551 of audio data not being written under certain circumstances
552 - audiod: compute the difference of server time and local time
553 correctly
554 - para_server/para_audiod: Fix some memory leaks
555 - documentation improvements
556 - configure.ac: fix checks for para_krell
557 - new man pages
558
559 -------------------------------------------
560 0.2.14 (2006-10-15) "transient singularity"
561 -------------------------------------------
562
563 The only major enhancement of this version is the osx writer which completes
564 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
565 until now for reasons beyond the scope of this changelog entry.
566
567 - new output plugin for Mac Os: the osx writer
568 - rename configure command line options from --enable-xxx-headers to
569 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
570 - configure: new command line options: --with-mad-headers,
571 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
572 - some robustness fixes
573 - dymamic audio format recognition for audiod
574 - para_server: new command line option: --autoplay_delay
575 - para_audiod: new command line option: --clock_diff_count
576
577 ---------------------------------------
578 0.2.13 (2006-07-14) "sonic convolution"
579 ---------------------------------------
580
581 A bunch of new features and core changes.
582
583 - the new paraslash scheduler, short and sweet.
584 - Support for m4a/mp4 files via the new aac audio format
585 handler/filter (requires libfaad).
586 - each writer has its own command line parser, just like
587 para_recv and para_filter.
588 - para_client and para_audioc use the error subsystem
589 - writers are integrated in para_audiod (currently linux-only)
590 - para_client is integrated in para_audiod
591 - random/playlist selector: improved info strings
592 - new audiod commands: tasks, kill
593 - update to libortp-0.10.1
594 - para_fade: wake time defaults to 8 hours from now
595 - update to autoconf-2.60
596
597 ------------------------------------------
598 0.2.12 (2006-05-12) "oriented abstraction"
599 ------------------------------------------
600
601 Many user-visible changes in this release and lots of new
602 features:
603
604
605 - the new optional dccp sender/receiver. It uses the datagram
606 congestion control protocol. You'll need a fairly new kernel
607 for this.
608 - paraslash works on Mac OS X (thanks to Gerd Becker)
609 - para_play renamed to para_write
610 - modular output plugin design (writers) for para_write
611 - new file_writer output plugin for para_write
612 - compress filter speed improvements
613 - update to libortp-0.9.1
614 - update to gengetopt-2.17rc
615 - para_client no longer depends on libreadline (as the
616 code for the interactive mode was removed).
617 - gcc-2-95 is no longer a supported compiler. It may still
618 work, but it gets no more testing.
619 - the tarball no longer contains the screenshot images which
620 reduces its size quite a bit.
621 - configure: new command line options: --enable-mysql-headers
622 and --enable-mysql-libs
623
624 ------------------------------------
625 0.2.11 (2006-03-11) "atomic duality"
626 ------------------------------------
627
628 Here it is, the first paraslash release developed with git. There
629 are fairly many user-visible changes in this release. As two out of
630 the three "database tools" of paraslash don't use a database at all,
631 they are now called "audio file selectors" instead.
632
633
634 - the cdt command (change database tool) becomes chs (change
635 selector)
636 - no more colon separators: The syntax of some options of
637 para_audiod and para_filter have changed. Use --help for
638 more info (and some examples).
639 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
640 - switch from cvs to git (should've done that earlier)
641 - the new ipc subsystem
642 - new audio file selector: playlist
643 - para_server: the dopey selector is now called "random",
644 and is the default selector. Use the --selector option to
645 choose another selector at startup, or the chs command to
646 change the selector at runtime.
647 - X86_64 fixes (thanks to Steffen Klassert)
648 - para_play fixes
649
650 --------------------------------------
651 0.2.10 (2006-02-17) "cyclic attractor"
652 --------------------------------------
653
654 Huge documentation update, a scrollable window for para_gui, ortp
655 improvements, and of course many small fixes not mentioned here.
656 The diffstat below is rather misleading as most insertions are due
657 to the new source documentation.
658
659 - autoconf cleanup
660 - para_server also uses the new error subsystem
661 - lots of new documentation (UTSL)
662 - gui improvements:
663 - keysyms for cursor keys and for next/previous page keys
664 - scrollable output window
665 - new internal commands: scroll up/down, page up/down
666 - fix color of command output.
667 - ortp: the --chunk_time and --header flags are no longer needed
668 for para_recv/para_audiod as this information is now encoded in
669 each rtp packet sent by para_server.
670
671 -------------------------------------------
672 0.2.9 (2006-01-24) "progressive turbulence"
673 -------------------------------------------
674
675 Internal audiod receivers/filters, the new error subsystem and
676 a lot of small improvements.
677
678 - para_recv and para_filter are integrated into the para_audiod
679 binary, i.e. audiod no longer spawns a new process for
680 each receiver/filter. As para_recv and para_filter might be
681 useful as standalone programs, they still get built (linked
682 against the same object files that are also used for audiod).
683 - further ortp timing improvements should reduce the CPU usage
684 of the ortp receiver.
685 - improved audio grabbing. The 'grab' command of para_audiod
686 has its own set of command line options. Read the output of
687 "para_audioc help grab" for more info.
688 - oggdec: configurable input prebuffer size.
689 - the new error subsystem gives better error diagnostics
690 and reduces code size.
691
692 -----------------------------------------
693 0.2.8 (2006-01-02) "dynamic accumulation"
694 -----------------------------------------
695
696 The new modular filter design and the para_play-hangs bugfix.
697
698 - new executable: para_filter. It combines para_mp3dec,
699 para_oggdec and para_compress. It also adds a further filter
700 type, wav, that just inserts a wave header at the desired point
701 of the filter chain. All 'piping' is done in-memory (i.e. no
702 read/write operations are used).
703 - para_play: fix a stupid bug that caused it to hang under
704 certain circumstances.
705
706 -------------------------------------------
707 0.2.7 (2006-12-27) "transparent invariance"
708 -------------------------------------------
709
710 Not many user-visible changes but a fair amount of internal improvements.
711
712
713 - The http sender buffers data if it can not be sent
714 out immediately (because the socket is not writable). This
715 should prevent para_server from shutting down the connection
716 too early on a loaded network.
717 - para_play also prebuffers data if it is told to start at a
718 future time by the --start_time option.
719 - The return of para_recv: It combines para_ortp_recv and
720 para_http_recv. Use the --receiver option to switch between
721 the two. para_recv builds without libortp, but contains
722 only the http receiver in this case.
723 - update to ortp 0.8.1. As this ortp release contains incompatible
724 changes, para_recv-0.2.7 won't link against older ortp libs.
725 - improved ortp timings.
726 - use of gcc-extensions that #define away for non-gcc and
727 gcc < 3.0.
728
729 -------------------------------------------
730 0.2.6 (2005-10-29) "recursive compensation"
731 -------------------------------------------
732
733 Transparent session encryption (uses openssl's Alleged RC4 cipher),
734 the internal find command and several other improvements and cleanups.
735
736 - Encrypt the session if encryption is requested by the client
737 (default for para_client 0.2.6). This is backwards
738 compatible, so older clients can still connect to para_server
739 0.2.6. Use the new client option --plain to request an
740 uncrypted session (off by default, must be set to on in
741 order to connect to para_server 0.2.x with 0 <= x <= 5).
742 - para_server uses an internal function to locate audio files
743 rather than calling find(1). The server option
744 --mysql_audio_file_dir replaces --mysql_find_cmd.
745 - documentation update
746 - man pages
747 - header file cleanup
748 - para_client code cleanup
749 - para_gui: faster display of output of display commands
750
751 ------------------------------------------
752 0.2.5 (2005-10-13) "aggressive resolution"
753 ------------------------------------------
754
755 This release adds internal senders, i.e. no more external programs are
756 spawned for sending out the audio data. There are two different senders
757 available: The http sender and the ortp sender (former para_send which
758 is no longer needed).
759
760 The new sender code has a plugin-like design so it can be easily
761 extended should there be be any future need for supporting another
762 network streaming protocol. All senders are completely independent of
763 each other. In particular, the http and the ortp sender can operate
764 in parallel.
765
766 - new server command: sender to control senders at runtime.
767 Read the output of "para_server -h" and "para_client help
768 sender" for more information.
769 - para_recv renamed to para_ortp_recv
770 - new executable: para_http_recv, a simple command line
771 http receiver.
772 - major afs/mp3/ogg code simplifications due to internal
773 senders.
774 - ogg timing improvements
775 - fix several minor memory leaks (found by valgrind)
776 - empty stream definitions work again
777 - com_ne(): ignore errors on remove
778 - audiod: fix segfault on server restart
779
780 ---------------------------------------
781 0.2.4 (2005-09-21) "toxic anticipation"
782 ---------------------------------------
783
784 Several small improvements, fixes and the new grab command.
785
786 - audiod:
787 - new command: "grab" to grab the output of the stream reader
788 or any filters. Read the output of "para_audioc help grab"
789 for more information.
790 - fix memory leak
791 - code cleanup
792 - audioc: new command line option: --bufsize to specify a
793 buffer size different from the default size 8192.
794 - improved error diagnostics for para_play.
795 - new configure option: --enable-ssldir so search for openssl in
796 non-standard places
797 - sdl_gui: Make it look nice again for 1024x768
798 - server: report total size of memory allocated with sbrk by malloc,
799 new command line option: --announce_time
800
801 -----------------------------------------
802 0.2.3 (2005-09-01) "hydrophilic movement"
803 -----------------------------------------
804
805 Two new executables and major feature enhancements.
806
807 - audiod filters: It is now possible to specify arbitrary many
808 (including none) filters for each supported audio
809 format. This can be used e.g. for normalizing volume,
810 transforming or grabbing the audio stream, or for using
811 visualizers. Read the output of "para_audiod -h" for the
812 syntax of the new --filter_cmd option.
813 - new executable: para_play, a tiny alsa player. It
814 can play wave files or raw pcm (16 bit little endian)
815 from stdin.
816 - new executable: para_compress, a dynamic range compressor
817 intended to keep audio output at a consistent volume. Derived
818 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
819 - audiod: New option: --stream_delay. This can be used in
820 a local network to syncronize the audio output of all
821 clients that play the same stream.
822
823 ------------------------------------------
824 0.2.2 (2005-08-19) "tangential excitation"
825 ------------------------------------------
826
827 Mostly internal changes in this release, but also some new commands
828 for the mysql database tool.
829
830 - cleanup exec.c, fix para_exec bug
831 - compile time loglevel (log messages below the given level
832 won't be compiled in, which reduces the size of the
833 resulting binaries)
834 - new log macros that shorten the size of the source code.
835 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
836 to send only zeros. With this workaround, para_audioc works
837 again.
838 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
839 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
840 (new entry), "snp" (set numplayed). Read the manual for more
841 information.
842
843 ---------------------------------------
844 0.2.1 (2005-08-15) "surreal experience"
845 ---------------------------------------
846
847 Here comes paraslash-0.2.1. It contains a couple of new features and,
848 surprise, only minor bug fixes.
849
850 - kill noisy mp3 debug message
851 - cleanup of the build system
852 - para_server and para_client directly use the crypto routines
853 of the openssl library rather than invoking the openssl command
854 line utitlity
855 - server/audiod: new option --user to switch to the given user
856 when invoked as root. Read the output of "para_server -h" for
857 more information.
858 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
859 status. Default: "para_audioc stat"
860 - sdl_gui: new option --pic_cmd to be used to download the picture.
861 Default: "para_client pic"
862 - audiod: 5 slots ought to be enough for everybody
863 - audiod: new status item: Uptime, kill hup command
864
865 ------------------------------------------
866 0.2.0 (2005-08-06) "distributed diffusion"
867 ------------------------------------------
868
869 After several month of increased development activity, paraslash-0.2.0
870 has arrived. It contains many new features and is much more
871 self-contained than the old 0.1.x series. Enjoy!
872
873
874 - para_server: fix hang on song change and crash on sighup.
875 Speed up mysql queries. The DIR_LIKE macro is gone.
876 - new executables: para_audiod, the local audio daemon that
877 starts playback (uses SCM_CREDENTIALS socket magic) and
878 para_audioc, the corresponding client.
879 - new executables: para_mp3dec/para_oggdec, two really teensy
880 decoders. para_mp3dec is based on libmad, para_oggdec requires
881 libvorbisfile.
882 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
883 they are now called para_send and para_recv respectively.
884 - documentation updates
885 - para_gui is themable. For now there is the default theme that
886 looks as before and the simple theme: blue and easy.
887 - gui: audio streaming is now handled by audiod. Time display shows
888 playback time rather than streaming time
889 - slider: update to libzmw-0.2.0
890 - para_krell: fix crash on server shutdown
891 - switch from gzip to bzip2
892
893 ----------------------------------------
894 0.1.7 (2005-04-18) "melting penetration"
895 ----------------------------------------
896
897 The main change in this release is clearly the oggvorbis rewrite,
898 but there are also lots of smaller changes. If you intend to use both
899 the mp3 and the ogg plugin, it is recommended to use software mixing,
900 e.g. the dmix plugin which is provided by ALSA.
901
902 - new executables: para_ovsend and para_ovrecv for sending/receiving
903 oggvorbis files via rtp. Requires the open rtp library. Get it at
904 http://www.linphone.org/ortp/
905 - rewrite of the ogg_vorbis core code
906 - configure detects libzmw and, if detected, includes
907 para_slider to the list of binaries to be built by make
908 - server stream writers read from their associated fifo rather
909 than from stdin
910 - slider: two new sliders, lastplayed and numplayed
911 - fix nasty double free bug which caused random segfaults in case of
912 mp3 files with invalid header information
913 - gui: new command line option: --stream_timeout=seconds to
914 deactivate a slot if it is idle for that many seconds (default=`5')
915 - diffstats
916
917 ---------------------------------------
918 0.1.6 (2005-03-05) "asymptotic balance"
919 ---------------------------------------
920
921 Only little user-visible changes in this release. Mainly bugfixes and
922 core code cleanup. This is probably the most stable version ever if you
923 stick to mp3...
924
925 - fix several memory leaks
926 - rename default name of mysql database from "music" to "paraslash".
927 Use para_server's --mysql_database option if you do not want to
928 rename your old database.
929 - rework ogg vorbis code
930 - make update command work on mysql servers with LOCAL_INFILE
931 disabled
932 - gui: improved stream I/O (slots)
933 - simplified audio format API
934 - para_pob_ogg is gone
935
936 ------------------------------------
937 0.1.5 (2004-12-31) "opaque eternity"
938 ------------------------------------
939
940 Let's slide gently into the new year.
941
942 - new: para_slider (not built automatically, type "make
943 para_slider" to build). A toy for those who always felt that
944 creating stream definitions is difficult. See screenshots,
945 README and FEATURES for more info.
946 - improved signal handling. Fixes server segfault on SIGHUP
947 for linux kernels newer than Aug 24 2004 and makes para_gui
948 race-free.
949 - reload database tool on SIGHUP
950 - improved help message for sl
951 - do not log "broken pipe" messages as errors. They are
952 perfectly ok.
953 - fix wrong error message on permission errors
954
955 -----------------------------------------
956 0.1.4 (2004-12-19) "tunneling transition"
957 -----------------------------------------
958
959 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
960 Hopefully, most of them got wiped out with this release. Some
961 enhancements went also in.
962
963 - improved error diagnostics for all commands
964 - stradd/picadd: overwrite previous contents if entry already
965 exists, rather than returning errors
966 - stradd: use current stream if invoked without args
967 - faster (and hopefully more stable) ogg-vorbis handling
968 - para_krell: reap children to avoid zombie-flooding in case
969 no server is running
970 - si: report also server pid
971 - server: don't busy-loop if dbtool reports only invalid files.
972 - gui: CTRL+C works again, fix stream_read command line option
973 - fix pic_add, hist
974 - fix mysql dbtool startup in case no database exists
975 - many small fixes and cleanups
976
977 ---------------------------------------
978 0.1.3: (2004-12-10) "vanishing inertia"
979 ---------------------------------------
980
981 Starting from this release, the database tools are integrated in the
982 server binary. This decreases server startup time, reduces code size
983 and speeds up database commands. However, the layout of the underlying
984 mysql database changed only slightly and 0.1.3 should be backwards
985 compatible in that respect.
986
987 Visible changes:
988
989 - If mysql is not detected at compile time, or fails to init
990 at runtime, fall back to the dopey database tool which should
991 always work.
992 - para_dbtool and dbtool.conf are gone. All mysql specific
993 options are read from server.conf and are prefixed by 'mysql_'.
994 - new command: cdt (change database tool)
995 - new command line option: dbtool (choose startup database tool)
996 - The name of current stream is now stored in the database,
997 so paraslash remembers its current stream when restarted.
998 - new command: csp (change stream and play)
999 - para_gui also reports current database tool and server uptime
1000
1001 -------------------------------------------
1002 0.1.2: (2004-11-28) "spherical fluctuation"
1003 -------------------------------------------
1004
1005 Point release before the big dbtool changes go in.
1006
1007 - dbtool: rename ca to cam (copy all meta data). It now also
1008 copies numplayed and lastplayed time as well as the picture
1009 id.
1010 - fix endless-loop-bug caused by mp3 files with invalid header
1011
1012 -----------------------------------------
1013 0.1.1: (2004-11-05) "floating atmosphere"
1014 -----------------------------------------
1015
1016 - gkrellm plugin
1017 - new dbtool command: mbox. Browse your sound-file collection
1018 with your favorite mail reader.
1019 - several small fixes
1020
1021 -------------------------------------
1022 0.1.0: (2004-10-22) "rotating cortex"
1023 -------------------------------------
1024
1025 - fix logging bug for loglevel > VERBOSE
1026 - fix skip command
1027 - correct timings for vbr mp3s
1028 - modular audio format support
1029 - ogg-vorbis support (experimental)
1030 - new server option: autoplay
1031
1032 -----------------------------------------
1033 0.0.99: (2004-07-25) "harmonic deviation"
1034 -----------------------------------------
1035
1036 - rename projectname from icc to paraslash (play, archive, rate
1037 and stream large audio sets happily)
1038 - paraslash is no longer restricted to one particular audio
1039 streaming software
1040 - new dbtool commands (stradd, strq, strdel) for easy stream
1041 managment w/o configuration file. That obsoletes stream_defs
1042 file/config option for dbtool.
1043 - picadd accepts jpeg data from stdin
1044 - new server commands: ps (select previous stream), sc (song change)
1045 - new default pictures for sdl_gui
