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

971 well as for invalid picture pointers
972 - fix long outstanding case sensitivity bug
973 - many small fixes and cleanups
974
975 -------------------
976 0.0.95 (2003-06-29)
977 -------------------
978
979 - sdl gui runs much faster
980 - new dbtool command: ca (copy attributes)
981 - count and display number of times the song has been played

985 - decrease network traffic of stat
986 - fix zombie bug
987 - many small fixes and cleanups
988
989 -------------------

1003 -------------------
1004
1005 - colors for icc_gui
1006 - icc_gui sets volume directly (linux only)
1007 - proper locking that fixes some races
1008 - fix security bug that caused commands to be executed even
1009 with unsufficient permissions
