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

972 -------------------
973
974 - easy stream_defs syntax
975 - sdl_gui can display images associated to the file being played
976 - Major feature enhancements for icc_gui including dynamic text
977 placement and the top/bottom window design
978 - vrfy/clean now also checks for NULL values in attributes as
979 well as for invalid picture pointers
980 - fix long outstanding case sensitivity bug
981 - many small fixes and cleanups
982
983 -------------------
984 0.0.95 (2003-06-29)
985 -------------------
986
987 - sdl gui runs much faster
988 - new dbtool command: ca (copy attributes)
989 - count and display number of times the song has been played
990 - new feature: scoring
991 - command line options for sdl_gui

993 - decrease network traffic of stat
994 - fix zombie bug
995 - many small fixes and cleanups
996
997 -------------------
998 0.0.94 (2003-05-04)
999 -------------------
1000
1001 - new server command: ns (next stream)
1002 - new icc_gui command: c (change stream)
1003 - internal mp3info
1004 - stat shows also id3 tag info
1005 - new sdl based gui
1006 - log flodding bug fixed
1007 - many small fixes and cleanups
1008
1009 -------------------
1010 0.0.93 (2003-03-28)
1011 -------------------
1012
1013 - colors for icc_gui
1014 - icc_gui sets volume directly (linux only)
1015 - proper locking that fixes some races
1016 - fix security bug that caused commands to be executed even
1017 with unsufficient permissions
1018 - new command: hup to make all servers reread their configuration file
1019 - icecast meta data streaming
1020 - many small fixes and cleanups
