1 -------------------------------------------
2 0.4.8 (to be announced) "nested assignment"
3 -------------------------------------------
4
5 Gcrypt support, the overhauled osx writer and regex format specifiers
6 are the highlights of this release.
7
8 - support for libgcrypt as a drop-in replacement for openssl.
9 Run configure --enable-cryptolib=gcrypt to link against
10 libgcrypt. The two crypto implementations are compatible to
11 each other, i.e. a para_client executable linked against
12 gcrypt can connect to para_server linked against libssl
13 and vice versa.
14 - Rewrite of the osx writer (output plugin for Mac OS).
15 - audiod: The format specifier for receivers, filters and
16 writers is now treated as a regular expression. This allows
17 to replace 5 lines in the config file (one for each audio
18 format) by one single line. See the manual for details.
19 - The *.cmdline.[ch] files are no longer contained in the released
20 tarballs. This reduces the size of the tarballs but requires
21 gengetopt to build the tarball.
22 - Compiles cleanly also with llvm/clang.
23 - Corrupt mp3 files are handled more gracefully.
24 - sched: Optimized zero timeouts.
25 - vss timeout cleanups.
26
27 --------------------------------------
28 0.4.7 (2011-06-01) "infinite rollback"
29 --------------------------------------
30
31 The new ao writer, support for ssh RSA keys and a couple of other
32 enhancements.
33
34 - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
35 platforms through the libao audio library.
36 - Support for RSA keys generated with ssh-keygen.
37 - configure: improved options for ogg/vorbis/speex.
38 - The git version reported by --version always matches HEAD.
39 - The autogen script detects the number of processors and
40 runs a parallel make if possible.
41 - Major cleanup of the crypto API.
42 - Documentation updates.
43
44 ------------------------------------------
45 0.4.6 (2011-03-31) "deterministic entropy"
46 ------------------------------------------
47
48 Lots of ogg/vorbis improvements, the new test suite, enhancements
49 for para_gui and a fair amount of other bug fixes.
50
51 - For DCCP/OGG streams the audio file header is only sent once
52 at the beginning of the stream rather than periodically
53 every five seconds. This reduces network traffic and the
54 FEC group size.
55 - The vorbis comment header is replaced by an empty dummy header
56 before the header is sent over the network. This also results in
57 less network traffic and smaller FEC groups.
58 - The new "test" make target allows to perform some sanity checks prior
59 to installing the package.
60 - ogg timing fixes and performance improvements
61 - Scheduler improvements
62 - Proper exit codes for para_write
63 - para_gui: New option --theme to select a startup theme. Several
64 other improvements and fixes.
65 - aacdec error message cleanups
66 - simplified color error handling
67
68 --------------------------------------------
69 0.4.5 (2010-12-17) "symmetric randomization"
70 --------------------------------------------
71
72 Bug fixes, internal cleanups and variable-sized FEC slices.
73
74 - Contains a fix for an invalid-free-bug in the ogg audio format
75 handler code.
76 - Switching off the DCCP sender works again.
77 - para_audiod handles crashes of para_server more robustly.
78 - Internal scheduler and writer cleanups.
79 - Reduced latency due to variable-sized FEC slices.
80 - Improved documentation and error diagnostics.
81 - The build of para_server is now optional, allowing the build
82 to succeed in case libosl is not installed.
83
84 ------------------------------------------
85 0.4.4 (2010-08-06) "persistent regularity"
86 ------------------------------------------
87
88 Support for yet another audio format, para_write improvements and
89 bug fixes.
90
91 - Support for the speex codec.
92 - Support for sample formats other than 16 bit little endian.
93 - error2.h is now created by a perl script which speeds up configure
94 considerably.
95 - Fix a bug in the aac decoder which could lead to segfaults in
96 para_filter/para_audiod.
97 - Fixes for autoconf-2.66.
98
99 ----------------------------------------
100 0.4.3 (2010-07-05) "imaginary radiation"
101 ----------------------------------------
102
103 Many improvements for the DCCP and the UDP transport, the new user
104 manual and the usual mix of bug fixes and internal improvements.
105
106 - FEC support for the DCCP sender (Gerrit Renker). The new
107 --dccp_max_slice_size, --dccp_data_slices_per_group and
108 --dccp_slices_per_group options can be used to set the FEC
109 parameters for the DCCP transport.
110 - DNS lookups for UDP targets (Gerrit Renker).
111 - The new user manual replaces the README, README.afs, REQUIREMENTS
112 and INSTALL documents.
113 - Fix an end-of-file detection bug in the oggdec filter.
114 - The new nonblock API.
115 - Both options of the oggdec filter have been removed.
116 - New debug mode for the internal scheduler.
117
118 ------------------------------------------
119 0.4.2 (2010-04-23) "associative expansion"
120 ------------------------------------------
121
122 It's been some time since the last release, but finally here is
123 paraslash-0.4.2. The bulk of the changes comes from the new buffer
124 tree API, but there are changes all over the tree. Mainly performance
125 and usability improvements, but also quite some bug fixes.
126
127 - The new buffer tree API.
128 - DCCP: Support for CCID negotiation (Gerrit Renker).
129 - UDP robustness fixes.
130 - The --bufsize option for mp3dec is gone as it no longer makes sense
131 for the new buffer tree API.
132 - Fix audible buffer underruns for wma streams.
133 - The alsa writer no longer prints meaningless underrun durations.
134 - audiod: Defaults work also for udp streams. If no filter is
135 given for an audio format that is received via upd, fecdec is
136 automatically added as the first filter (along with the decoder).
137
138 ---------------------------------------
139 0.4.1 (2009-12-22) "concurrent horizon"
140 ---------------------------------------
141
142 Support for another audio format, minor feature enhancements and lots of bug
143 fixes. All fixes that have been accumulated in the maint branch (in particular
144 those mentionened in the 0.3.6 release notes) appear in this release as well.
145
146 - wma support.
147 - new afh option: --human to activate human-readable output.
148 - new server/audiod option: --log-timing to print timing information.
149 - build system improvements.
150 - source code documentation updates.
151
152 -------------------------------------
153 0.3.6 (2009-12-07) "cubic continuity"
154 -------------------------------------
155
156 Quite a few bugs have been found and fixed since 0.3.5, so here's
157 another 0.3.x release. No new features.
158
159 - Always check return value of malloc().
160 - ogg vorbis/FEC: Do not write garbage after the audio file header.
161 - exit if root privileges could not be dropped.
162 - FEC: Fix computation of extra slices.
163 - oss: Fix check for empty input buffer.
164 - Avoid buffer underruns due to filter chain output buffer constraints.
165 - server: Fix assignment of afs_pid.
166 - Don't panic if the afs database contains unknown audio formats.
167 - http/dccp: Do not send the audio file header twice.
168 - FEC: Timing improvements.
169
170 ----------------------------------------------
171 0.4.0 (2009-11-10) "simultaneous independence"
172 ----------------------------------------------
173
174 Two significant changes which require the new version number: The
175 improved authentication dialog and the fact that the database code
176 has been moved to a library, libosl. To use the new version, you have
177 to generate new RSA keys, see INSTALL for details. A shell script is
178 provided for conversion of the 0.3 database to the new 0.4 format.
179
180 - stronger crypto for client authentication
181 - the database code has been moved to a library
182 - improved status item handling
183 - cleanup of the build system
184 - The "-V" option now also prints the git version
185 - the new parser-friendly listing mode for the ls and stat commands
186 - mandatory rc4 encryption
187 - major audio format handler cleanups
188 - (id3,...) tags are no longer stored as a combined string in the database
189 - new mood methods: artist_matches, title_matches, comment_matches,
190 album_matches, year_maches, year.
191
192 --------------------------------------------
193 0.3.5 (2009-09-21) "symplectic separability"
194 --------------------------------------------
195
196 Full client support for *BSD Unixes, complete re-write of the ogg
197 vorbis audio format handler, various improvements all over the place
198 and the usual mix of bugfixes. This release marks the end of the 0.3
199 series if no serious problems show up.
200
201 - the new oss writer (supported on *BSD and Linux)
202 - rewrite of the ogg vorbis audio format handler. It's
203 recommended to replace the chunk tables of existing ogg
204 vorbis files in the afs database by re-adding these files
205 with "add -f".
206 - support for netmask subsets (Gerrit Renker)
207 - the new prebuffer filter
208 - improved signal handling
209 - variable fec output buffer size
210 - improved FEC timing fixes audible buffer underruns in UDP mode
211 - --log_color actually works
212 - new ls option: -d (print dates as seconds after the epoch)
213 - update to gengetopt 2.22.2
214 - support for RSA keys of size > 512 bits
215 - new option "mixer_channel" for para_fade
216
217 -----------------------------------------
218 0.3.4 (2009-05-07) "elliptic inheritance"
219 -----------------------------------------
220
221 The new udp sender, forward error correction, colored logs and various
222 other improvements. As the udp sender does not depend on any special
223 libraries, it is built unconditionally.
224
225 - The udp sender replaces the ortp sender. The new code uses forward
226 error correction to protect against packet losses. Many thanks to
227 Gerrit Renker for providing ipv6 support.
228 - The default port for udp streaming now defaults to 8000, like
229 for the http and the dccp senders/receivers.
230 - Loglevels are now specified as symbolic names, e.g.
231 "--loglevel info".
232 - improved ipv4 and ipv6 URI parser (Gerrit Renker).
233 - para_server/para_audiod: Color support for log messages.
234 - new options for mp3dec: --ignore-crc, --bufsize
235 - new audiod option: --config-file.
236 - gengetopt cleanups.
237 - Improved help/man pages: The documentation of para_audiod,
238 para_recv, para_filter and para_write now also contains
239 all options of the available receivers/filters/writers. The
240 man page of para_fade contains a description of the different
241 modes of operation.
242 - More source code documentation.
243 - vss timing fixes.
244
245 --------------------------------------------
246 0.3.3 (2008-12-01) "axiomatic perspectivity"
247 --------------------------------------------
248
249 Internal code cleanups, bug fixes, improved tag handling and the new
250 amplification filter.
251
252 - para_server uses the generic scheduling code.
253 - overhaul of the virtual streaming system.
254 - mp3: id3 version 2 support via libid3tag (optional)
255 - ogg: vorbis comment support.
256 - aac meta info support.
257 - mp3 audio format handler cleanups.
258 - new filter: "amp" to amplify the amplitude of the audio stream
259 - new status item/database entry: amplification. It is
260 used by the amp filter to pre-amplify the audio stream.
261 - fix a close-without-open bug in para_write.
262 - fix a bug in com_init() which was introduced in 0.3.2.
263 - better error diagnostics for para_client.
264
265 -----------------------------------------
266 0.3.2 (2008-04-11) "probabilistic parity"
267 -----------------------------------------
268
269 The new para_afh executable, scheduling and documentation improvements.
270
271 - new ls option: -lc (list chunk table)
272 - new executable: para_afh, the stand-alone audio file handler tool
273 - afs commands can send output more than SHMMAX (32MB on Linux). This
274 also reduces the memory usage of commands that produce large amounts
275 of output.
276 - major scheduler and audiod cleanups.
277 - more detailed and much nicer man pages.
278
279 ---------------------------------------
280 0.3.1 (2008-02-23) "liquid interaction"
281 ---------------------------------------
282
283 A mix of cleanups, bug fixes, improvements, and some new features. No
284 significant changes to the new database (osl) code, which is generally
285 a good sign.
286
287 - Share some similar/duplicate code between the http and the
288 dccp sender.
289 - Generic access control lists for paraslash senders.
290 - dccp sender: Access control lists, connection limiting and support
291 for the allow,deny,on,off,help sender commands.
292 - The default dccp port changed from 5001 to 8000 (suggested by
293 Gerrit Renker).
294 - para_server starts even if not all public keys could be loaded.
295 - Audiod performance improvements.
296 - fix a bug in the "off" command of the http sender.
297 - fix some fd and memory leaks.
298 - Update to gengetopt-2.22.
299
300 -------------------------------------
301 0.3.0 (2008-01-12) "solar saturation"
302 -------------------------------------
303
304 paraslash.0.3.0 -- 'WWDBND --what would databases never do?'.
305
306
307 Usually one might expect lots of new features AND a big increase in size
308 for a major release like this.
309
310 However, paraslash-0.3.0.tar.bz2 is the smallest paraslash tarball
311 ever. The decrease in size is mostly due to the removal of some
312 graphical tools (which were only quick hacks anyway). But also the
313 fact that the mysql code is gone cuts down the size a bit.
314
315 Being independent of mysql comes at a cost: The fact that paraslash
316 now contains its own database (the object storage layer, osl) increases
317 the (stripped) binary size of para_server by ~50K on i386.
318
319 - no more restrictions on unique basenames.
320 - independent of mysql: The new self-contained object
321 storage layer (osl) replaces the mysql database.
322 - New executable para_fsck: Check integrity of osl tables.
323 - Lyrics support.
324 - Reliable audio file move/rename detection.
325 - More portable than ever: Tested on Linux (x86_32, x86_64, sparc64),
326 MacOS (ppc32, x86_32), FreeBSD (x86_32), NetBSD (x86_32) and
327 Solaris (sparc64).
328 - the new osl-based audio file selector (afs) replaces the random,
329 the playlist and the mysql selector of paraslash-0.2.x.
330 - IPv6 support (thanks to Gerrit Renker).
331 - paraslash-0.2.x streams are now called "moods". Writing
332 0.3.x-mood definitions should be both easier and more
333 powerful than writing 0.2.x-stream definitions.
334 - para_krell, para_slider, para_para_sdl_gui, para_dbadm have
335 been removed. The world is a better place without them. However,
336 para_gui is still there.
337 - afs tracks audio file selection also in playlist mode.
338 - few easy-to-use afs commands replace the many not-so-easy-to-use
339 mysql commands (and are available also in playlist mode).
340 - Improved error subsystem.
341 - The earth-shaking new logo.
342
343 -----------------------------------------
344 0.2.17 (2007-11-20) "isotropic threshold"
345 -----------------------------------------
346
347 Mainly bugfixes and cleanups in this version which marks the end of
348 the 0.2.x series if no serious bugs show up after the release.
349
350 - mysql_selector: fix a locking bug.
351 - universal chunk queueing.
352 - dccp sender uses chunk queueing if write() returns EAGAIN (thanks
353 to Gerrit Renker).
354 - be more carful wrt. signed vs. unsigned argument passing.
355 - cleanup error.h and fix some references to invalid error
356 codes.
357 - update to gengetopt-2.21.
358 - update to ortp-0.13.1.
359 - autoconf: extend checks for headers, library functions and
360 compiler characteristics.
361 - Fix streaming of large mp3 files.
362 - Fix an off-by-one bug in playlist handling.
363
364 --------------------------------------
365 0.2.16 (2007-04-05) "neural discharge"
366 --------------------------------------
367
368 The main change in this release is the major audio format handler
369 cleanup which removes some similar/duplicate code and makes it easier
370 to implement plugins for other audio formats. Of course, the usual mix
371 of other improvements/changes/bugfixes also made it into the release.
372
373 - simplified audio format handlers (most of the handling functions
374 were moved one layer up to the virtual streaming system).
375 - para_server uses mmap to read audio files
376 - repositioning of mp3 streams is much faster, in particular for
377 jumping near the end of large mp3 files.
378 - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
379 and AFS_WRITE.
380 - fix a bug in para_filter that caused decoding of aac files
381 to start only after a few seconds.
382 - fix osx_writer hangs
383 - simplified dccp code (thanks to Gerrit Renker)
384 - the compress filter works also on big endian systems (ppc)
385
386 -----------------------------------------
387 0.2.15 (2007-02-16) "inductive resonance"
388 -----------------------------------------
389
390 Minor improvements, more documentation and a bunch of bug fixes.
391
392 - para_server: The server.users file is only read once on server
393 startup rather than for each connection
394 - mp3dec: Fix decoding of corrupt mp3 files
395 - afs (audio file sender) is now called vss (virtual streaming
396 system). Consequently, the permission flags specified in
397 ~/.paraslash/server.users have also changed: AFS_READ and AFS_WRITE
398 become VSS_READ and VSS_WRITE respectively.
399 - para_audiod/para_filter: Fix a bug that caused the last chunk
400 of audio data not being written under certain circumstances
401 - audiod: compute the difference of server time and local time
402 correctly
403 - para_server/para_audiod: Fix some memory leaks
404 - documentation improvements
405 - configure.ac: fix checks for para_krell
406 - new man pages
407
408 -------------------------------------------
409 0.2.14 (2006-10-15) "transient singularity"
410 -------------------------------------------
411
412 The only major enhancement of this version is the osx writer which completes
413 the Mac OS Port and was originally planned already for 0.2.13 but had to wait
414 until now for reasons beyond the scope of this changelog entry.
415
416 - new output plugin for Mac Os: the osx writer
417 - rename configure command line options from --enable-xxx-headers to
418 --with-xxx-headers and --enable-xxx-libs to --with-xxx-libs
419 - configure: new command line options: --with-mad-headers,
420 --with-mad-libs, --with-oggvorbis-headers, and --with-oggvorbis-libs
421 - some robustness fixes
422 - dymamic audio format recognition for audiod
423 - para_server: new command line option: --autoplay_delay
424 - para_audiod: new command line option: --clock_diff_count
425
426 ---------------------------------------
427 0.2.13 (2006-07-14) "sonic convolution"
428 ---------------------------------------
429
430 A bunch of new features and core changes.
431
432 - the new paraslash scheduler, short and sweet.
433 - Support for m4a/mp4 files via the new aac audio format
434 handler/filter (requires libfaad).
435 - each writer has its own command line parser, just like
436 para_recv and para_filter.
437 - para_client and para_audioc use the error subsystem
438 - writers are integrated in para_audiod (currently linux-only)
439 - para_client is integrated in para_audiod
440 - random/playlist selector: improved info strings
441 - new audiod commands: tasks, kill
442 - update to libortp-0.10.1
443 - para_fade: wake time defaults to 8 hours from now
444 - update to autoconf-2.60
445
446
447 ------------------------------------------
448 0.2.12 (2006-05-12) "oriented abstraction"
449 ------------------------------------------
450
451 Many user-visible changes in this release and lots of new
452 features:
453
454
455 - the new optional dccp sender/receiver. It uses the datagram
456 congestion control protocol. You'll need a fairly new kernel
457 for this.
458 - paraslash works on Mac OS X (thanks to Gerd Becker)
459 - para_play renamed to para_write
460 - modular output plugin design (writers) for para_write
461 - new file_writer output plugin for para_write
462 - compress filter speed improvements
463 - update to libortp-0.9.1
464 - update to gengetopt-2.17rc
465 - para_client no longer depends on libreadline (as the
466 code for the interactive mode was removed).
467 - gcc-2-95 is no longer a supported compiler. It may still
468 work, but it gets no more testing.
469 - the tarball no longer contains the screenshot images which
470 reduces its size quite a bit.
471 - configure: new command line options: --enable-mysql-headers
472 and --enable-mysql-libs
473
474 ------------------------------------
475 0.2.11 (2006-03-11) "atomic duality"
476 ------------------------------------
477
478 Here it is, the first paraslash release developed with git. There
479 are fairly many user-visible changes in this release. As two out of
480 the three "database tools" of paraslash don't use a database at all,
481 they are now called "audio file selectors" instead.
482
483
484 - the cdt command (change database tool) becomes chs (change
485 selector)
486 - no more colon separators: The syntax of some options of
487 para_audiod and para_filter have changed. Use --help for
488 more info (and some examples).
489 - update to gengetopt-2.16 (thanks to Lorenzo Bettini)
490 - switch from cvs to git (should've done that earlier)
491 - the new ipc subsystem
492 - new audio file selector: playlist
493 - para_server: the dopey selector is now called "random",
494 and is the default selector. Use the --selector option to
495 choose another selector at startup, or the chs command to
496 change the selector at runtime.
497 - X86_64 fixes (thanks to Steffen Klassert)
498 - para_play fixes
499
500
501 --------------------------------------
502 0.2.10 (2006-02-17) "cyclic attractor"
503 --------------------------------------
504
505 Huge documentation update, a scrollable window for para_gui, ortp
506 improvements, and of course many small fixes not mentioned here.
507 The diffstat below is rather misleading as most insertions are due
508 to the new source documentation.
509
510 - autoconf cleanup
511 - para_server also uses the new error subsystem
512 - lots of new documentation (UTSL)
513 - gui improvements:
514 - keysyms for cursor keys and for next/previous page keys
515 - scrollable output window
516 - new internal commands: scroll up/down, page up/down
517 - fix color of command output.
518 - ortp: the --chunk_time and --header flags are no longer needed
519 for para_recv/para_audiod as this information is now encoded in
520 each rtp packet sent by para_server.
521
522
523 -------------------------------------------
524 0.2.9 (2006-01-24) "progressive turbulence"
525 -------------------------------------------
526
527 Internal audiod receivers/filters, the new error subsystem and
528 a lot of small improvements.
529
530 - para_recv and para_filter are integrated into the para_audiod
531 binary, i.e. audiod no longer spawns a new process for
532 each receiver/filter. As para_recv and para_filter might be
533 useful as standalone programs, they still get built (linked
534 against the same object files that are also used for audiod).
535 - further ortp timing improvements should reduce the CPU usage
536 of the ortp receiver.
537 - improved audio grabbing. The 'grab' command of para_audiod
538 has its own set of command line options. Read the output of
539 "para_audioc help grab" for more info.
540 - oggdec: configurable input prebuffer size.
541 - the new error subsystem gives better error diagnostics
542 and reduces code size.
543
544
545 -----------------------------------------
546 0.2.8 (2006-01-02) "dynamic accumulation"
547 -----------------------------------------
548
549 The new modular filter design and the para_play-hangs bugfix.
550
551 - new executable: para_filter. It combines para_mp3dec,
552 para_oggdec and para_compress. It also adds a further filter
553 type, wav, that just inserts a wave header at the desired point
554 of the filter chain. All 'piping' is done in-memory (i.e. no
555 read/write operations are used).
556 - para_play: fix a stupid bug that caused it to hang under
557 certain circumstances.
558
559
560 -------------------------------------------
561 0.2.7 (2006-12-27) "transparent invariance"
562 -------------------------------------------
563
564 Not many user-visible changes but a fair amount of internal improvements.
565
566
567 - The http sender buffers data if it can not be sent
568 out immediately (because the socket is not writable). This
569 should prevent para_server from shutting down the connection
570 too early on a loaded network.
571 - para_play also prebuffers data if it is told to start at a
572 future time by the --start_time option.
573 - The return of para_recv: It combines para_ortp_recv and
574 para_http_recv. Use the --receiver option to switch between
575 the two. para_recv builds without libortp, but contains
576 only the http receiver in this case.
577 - update to ortp 0.8.1. As this ortp release contains incompatible
578 changes, para_recv-0.2.7 won't link against older ortp libs.
579 - improved ortp timings.
580 - use of gcc-extensions that #define away for non-gcc and
581 gcc < 3.0.
582
583
584 -------------------------------------------
585 0.2.6 (2005-10-29) "recursive compensation"
586 -------------------------------------------
587
588 Transparent session encryption (uses openssl's Alleged RC4 cipher),
589 the internal find command and several other improvements and cleanups.
590
591 - Encrypt the session if encryption is requested by the client
592 (default for para_client 0.2.6). This is backwards
593 compatible, so older clients can still connect to para_server
594 0.2.6. Use the new client option --plain to request an
595 uncrypted session (off by default, must be set to on in
596 order to connect to para_server 0.2.x with 0 <= x <= 5).
597 - para_server uses an internal function to locate audio files
598 rather than calling find(1). The server option
599 --mysql_audio_file_dir replaces --mysql_find_cmd.
600 - documentation update
601 - man pages
602 - header file cleanup
603 - para_client code cleanup
604 - para_gui: faster display of output of display commands
605
606
607 ------------------------------------------
608 0.2.5 (2005-10-13) "aggressive resolution"
609 ------------------------------------------
610
611 This release adds internal senders, i.e. no more external programs are
612 spawned for sending out the audio data. There are two different senders
613 available: The http sender and the ortp sender (former para_send which
614 is no longer needed).
615
616 The new sender code has a plugin-like design so it can be easily
617 extended should there be be any future need for supporting another
618 network streaming protocol. All senders are completely independent of
619 each other. In particular, the http and the ortp sender can operate
620 in parallel.
621
622 - new server command: sender to control senders at runtime.
623 Read the output of "para_server -h" and "para_client help
624 sender" for more information.
625 - para_recv renamed to para_ortp_recv
626 - new executable: para_http_recv, a simple command line
627 http receiver.
628 - major afs/mp3/ogg code simplifications due to internal
629 senders.
630 - ogg timing improvements
631 - fix several minor memory leaks (found by valgrind)
632 - empty stream definitions work again
633 - com_ne(): ignore errors on remove
634 - audiod: fix segfault on server restart
635
636
637 ---------------------------------------
638 0.2.4 (2005-09-21) "toxic anticipation"
639 ---------------------------------------
640
641 Several small improvements, fixes and the new grab command.
642
643 - audiod:
644 - new command: "grab" to grab the output of the stream reader
645 or any filters. Read the output of "para_audioc help grab"
646 for more information.
647 - fix memory leak
648 - code cleanup
649 - audioc: new command line option: --bufsize to specify a
650 buffer size different from the default size 8192.
651 - improved error diagnostics for para_play.
652 - new configure option: --enable-ssldir so search for openssl in
653 non-standard places
654 - sdl_gui: Make it look nice again for 1024x768
655 - server: report total size of memory allocated with sbrk by malloc,
656 new command line option: --announce_time
657
658
659 -----------------------------------------
660 0.2.3 (2005-09-01) "hydrophilic movement"
661 -----------------------------------------
662
663 Two new executables and major feature enhancements.
664
665 - audiod filters: It is now possible to specify arbitrary many
666 (including none) filters for each supported audio
667 format. This can be used e.g. for normalizing volume,
668 transforming or grabbing the audio stream, or for using
669 visualizers. Read the output of "para_audiod -h" for the
670 syntax of the new --filter_cmd option.
671 - new executable: para_play, a tiny alsa player. It
672 can play wave files or raw pcm (16 bit little endian)
673 from stdin.
674 - new executable: para_compress, a dynamic range compressor
675 intended to keep audio output at a consistent volume. Derived
676 from AudioCompress, http://trikuare.cx/code/AudioCompress.html.
677 - audiod: New option: --stream_delay. This can be used in
678 a local network to syncronize the audio output of all
679 clients that play the same stream.
680
681
682 ------------------------------------------
683 0.2.2 (2005-08-19) "tangential excitation"
684 ------------------------------------------
685
686 Mostly internal changes in this release, but also some new commands
687 for the mysql database tool.
688
689 - cleanup exec.c, fix para_exec bug
690 - compile time loglevel (log messages below the given level
691 won't be compiled in, which reduces the size of the
692 resulting binaries)
693 - new log macros that shorten the size of the source code.
694 - workaround a gcc-4.1 bug (?) that caused send_cred_buffer()
695 to send only zeros. With this workaround, para_audioc works
696 again.
697 - avoid gcc-4 warning: conflicting types for built-in function 'clog'
698 - new mysql commands: "rm" (remove entry), "mv" (rename entry) "ne"
699 (new entry), "snp" (set numplayed). Read the manual for more
700 information.
701
702
703 ---------------------------------------
704 0.2.1 (2005-08-15) "surreal experience"
705 ---------------------------------------
706
707 Here comes paraslash-0.2.1. It contains a couple of new features and,
708 surprise, only minor bug fixes.
709
710 - kill noisy mp3 debug message
711 - cleanup of the build system
712 - para_server and para_client directly use the crypto routines
713 of the openssl library rather than invoking the openssl command
714 line utitlity
715 - server/audiod: new option --user to switch to the given user
716 when invoked as root. Read the output of "para_server -h" for
717 more information.
718 - gui/sdl_gui: new option --stat_cmd to be used to retrieve the
719 status. Default: "para_audioc stat"
720 - sdl_gui: new option --pic_cmd to be used to download the picture.
721 Default: "para_client pic"
722 - audiod: 5 slots ought to be enough for everybody
723 - audiod: new status item: Uptime, kill hup command
724
725
726
727 ------------------------------------------
728 0.2.0 (2005-08-06) "distributed diffusion"
729 ------------------------------------------
730
731 After several month of increased development activity, paraslash-0.2.0
732 has arrived. It contains many new features and is much more
733 self-contained than the old 0.1.x series. Enjoy!
734
735
736 - para_server: fix hang on song change and crash on sighup.
737 Speed up mysql queries. The DIR_LIKE macro is gone.
738 - new executables: para_audiod, the local audio daemon that
739 starts playback (uses SCM_CREDENTIALS socket magic) and
740 para_audioc, the corresponding client.
741 - new executables: para_mp3dec/para_oggdec, two really teensy
742 decoders. para_mp3dec is based on libmad, para_oggdec requires
743 libvorbisfile.
744 - ovsend/ovrecv are capable of streaming ogg as well as mp3, so
745 they are now called para_send and para_recv respectively.
746 - documentation updates
747 - para_gui is themable. For now there is the default theme that
748 looks as before and the simple theme: blue and easy.
749 - gui: audio streaming is now handled by audiod. Time display shows
750 playback time rather than streaming time
751 - slider: update to libzmw-0.2.0
752 - para_krell: fix crash on server shutdown
753 - switch from gzip to bzip2
754
755
756 ----------------------------------------
757 0.1.7 (2005-04-18) "melting penetration"
758 ----------------------------------------
759
760 The main change in this release is clearly the oggvorbis rewrite,
761 but there are also lots of smaller changes. If you intend to use both
762 the mp3 and the ogg plugin, it is recommended to use software mixing,
763 e.g. the dmix plugin which is provided by ALSA.
764
765 - new executables: para_ovsend and para_ovrecv for sending/receiving
766 oggvorbis files via rtp. Requires the open rtp library. Get it at
767 http://www.linphone.org/ortp/
768 - rewrite of the ogg_vorbis core code
769 - configure detects libzmw and, if detected, includes
770 para_slider to the list of binaries to be built by make
771 - server stream writers read from their associated fifo rather
772 than from stdin
773 - slider: two new sliders, lastplayed and numplayed
774 - fix nasty double free bug which caused random segfaults in case of
775 mp3 files with invalid header information
776 - gui: new command line option: --stream_timeout=seconds to
777 deactivate a slot if it is idle for that many seconds (default=`5')
778 - diffstats
779
780
781 ---------------------------------------
782 0.1.6 (2005-03-05) "asymptotic balance"
783 ---------------------------------------
784
785 Only little user-visible changes in this release. Mainly bugfixes and
786 core code cleanup. This is probably the most stable version ever if you
787 stick to mp3...
788
789 - fix several memory leaks
790 - rename default name of mysql database from "music" to "paraslash".
791 Use para_server's --mysql_database option if you do not want to
792 rename your old database.
793 - rework ogg vorbis code
794 - make update command work on mysql servers with LOCAL_INFILE
795 disabled
796 - gui: improved stream I/O (slots)
797 - simplified audio format API
798 - para_pob_ogg is gone
799
800 ------------------------------------
801 0.1.5 (2004-12-31) "opaque eternity"
802 ------------------------------------
803
804 Let's slide gently into the new year.
805
806 - new: para_slider (not built automatically, type "make
807 para_slider" to build). A toy for those who always felt that
808 creating stream definitions is difficult. See screenshots,
809 README and FEATURES for more info.
810 - improved signal handling. Fixes server segfault on SIGHUP
811 for linux kernels newer than Aug 24 2004 and makes para_gui
812 race-free.
813 - reload database tool on SIGHUP
814 - improved help message for sl
815 - do not log "broken pipe" messages as errors. They are
816 perfectly ok.
817 - fix wrong error message on permission errors
818
819 -----------------------------------------
820 0.1.4 (2004-12-19) "tunneling transition"
821 -----------------------------------------
822
823 Bugfix release. As expected, 0.1.3 introduced a bunch of new bugs.
824 Hopefully, most of them got wiped out with this release. Some
825 enhancements went also in.
826
827 - improved error diagnostics for all commands
828 - stradd/picadd: overwrite previous contents if entry already
829 exists, rather than returning errors
830 - stradd: use current stream if invoked without args
831 - faster (and hopefully more stable) ogg-vorbis handling
832 - para_krell: reap children to avoid zombie-flooding in case
833 no server is running
834 - si: report also server pid
835 - server: don't busy-loop if dbtool reports only invalid files.
836 - gui: CTRL+C works again, fix stream_read command line option
837 - fix pic_add, hist
838 - fix mysql dbtool startup in case no database exists
839 - many small fixes and cleanups
840
841 ---------------------------------------
842 0.1.3: (2004-12-10) "vanishing inertia"
843 ---------------------------------------
844
845 Starting from this release, the database tools are integrated in the
846 server binary. This decreases server startup time, reduces code size
847 and speeds up database commands. However, the layout of the underlying
848 mysql database changed only slightly and 0.1.3 should be backwards
849 compatible in that respect.
850
851 Visible changes:
852
853 - If mysql is not detected at compile time, or fails to init
854 at runtime, fall back to the dopey database tool which should
855 always work.
856 - para_dbtool and dbtool.conf are gone. All mysql specific
857 options are read from server.conf and are prefixed by 'mysql_'.
858 - new command: cdt (change database tool)
859 - new command line option: dbtool (choose startup database tool)
860 - The name of current stream is now stored in the database,
861 so paraslash remembers its current stream when restarted.
862 - new command: csp (change stream and play)
863 - para_gui also reports current database tool and server uptime
864
865
866 -------------------------------------------
867 0.1.2: (2004-11-28) "spherical fluctuation"
868 -------------------------------------------
869
870 Point release before the big dbtool changes go in.
871
872 - dbtool: rename ca to cam (copy all meta data). It now also
873 copies numplayed and lastplayed time as well as the picture
874 id.
875 - fix endless-loop-bug caused by mp3 files with invalid header
876
877 -----------------------------------------
878 0.1.1: (2004-11-05) "floating atmosphere"
879 -----------------------------------------
880
881 - gkrellm plugin
882 - new dbtool command: mbox. Browse your sound-file collection
883 with your favorite mail reader.
884 - several small fixes
885
886 -------------------------------------
887 0.1.0: (2204-10-22) "rotating cortex"
888 -------------------------------------
889
890 - fix logging bug for loglevel > VERBOSE
891 - fix skip command
892 - correct timings for vbr mp3s
893 - modular audio format support
894 - ogg-vorbis support (experimental)
895 - new server option: autoplay
896
897 -----------------------------------------
898 0.0.99: (2004-07-25) "harmonic deviation"
899 -----------------------------------------
900
901 - rename projectname from icc to paraslash (play, archive, rate
902 and stream large audio sets happily)
903 - paraslash is no longer restricted to one particular audio
904 streaming software
905 - new dbtool commands (stradd, strq, strdel) for easy stream
906 managment w/o configuration file. That obsoletes stream_defs
907 file/config option for dbtool.
908 - picadd accepts jpeg data from stdin
909 - new server commands: ps (select previous stream), sc (song change)
910 - new default pictures for sdl_gui
911 - gui: new key_map option for binding commands and internal
912 functions to arbitrary keys, nice help screen, rip out
913 soundcard/linux specific stuff, avoid noise artefacts while jumping,
914 show silly logo on startup
915 - new executables: para_fade for fading volume, para_dbadm for
916 manipulating attributes
917 - cdb adds _all_ tables to mysql database
918 - revised and beautified documentation
919 - sample dbtool rewritten in C
920 - autoconf
921
922 ---------------------------------------------
923 0.0.98: (2003-12-26) "incremental smoothness"
924 ---------------------------------------------
925
926 - kick icecast in favour of poc. That removes some races and reduces
927 core code considerably.
928 - cbr/vbr is displayed by stat and gui/sdl_gui. New status flags
929 give finer info on afs' status.
930 - gui can start decoder (see config options). Further new gui
931 commands: refresh (^L), jmp (F1-F10)
932 - gui rereads conf on SIGUSR1 instead of SIGHUP. SIGHUP
933 terminates gui. This fixes dead instances consuming memory
934 continuously.
935 - new dbtool command: verb for sending verbatim sql queries.
936 - fix pid_list races (by removing pid_list)
937 - codename funnies
938
939 --------------------
940 0.0.97: (2003-10-26)
941 --------------------
942
943 - installation prefix now defaults to /usr/local
944 - new commands for gui: snozze, sleep and reread config
945 - config file for gui and sdl_gui
946 - fix problems with filenames containing funny characters
947 (reported by Thomas Forell)
948 - improved signal handling for gui, now it rereads conf on SIGHUP
949 - new dbtool command: cdb (create database)
950 - switch from argtable to gengetopt
951 - major code cleanup and speed improvements
952 - fix several potential buffer overflows
953 - many small fixes and cleanups
954
955 -------------------
956 0.0.96 (2003-08-30)
957 -------------------
958
959 - easy stream_defs syntax
960 - sdl_gui can display images associated to the file being played
961 - Major feature enhancements for icc_gui including dynamic text
962 placement and the top/bottom window design
963 - vrfy/clean now also checks for NULL values in attributes as
964 well as for invalid picture pointers
965 - fix long outstanding case sensitivity bug
966 - many small fixes and cleanups
967
968 -------------------
969 0.0.95 (2003-06-29)
970 -------------------
971
972 - sdl gui runs much faster
973 - new dbtool command: ca (copy attributes)
974 - count and display number of times the song has been played
975 - new feature: scoring
976 - command line options for sdl_gui

978 - decrease network traffic of stat
979 - fix zombie bug
980 - many small fixes and cleanups
981
982 -------------------
983 0.0.94 (2003-05-04)
984 -------------------
985
986 - new server command: ns (next stream)

994 -------------------
995 0.0.93 (2003-03-28)
996 -------------------
997
998 - colors for icc_gui
999 - icc_gui sets volume directly (linux only)
1000 - proper locking that fixes some races
1001 - fix security bug that caused commands to be executed even
1002 with unsufficient permissions
1003 - new command: hup to make all servers reread their configuration file
1004 - icecast meta data streaming
1005 - many small fixes and cleanups
