Liquidsoap 1.0.0

Finally, the 1.0.0 release! It brings several important fixes, but also some nice novelties. The most outstanding difference concerns output.icecast(): its restart and restart_delay parameters are gone, replaced by a new on_stop handler which is called on every error (failed connection or disconnection) and returns the new restart delay. The on_error handler receives a string describing the error which enables user-friendly reporting, adaptative
delays, etc. Note that on_error defaults to fun(_)->3. which is equivalent to having restart=true, restart_delay=3. in previous versions, NOT the same as the former restart=false default. As a result, Liquidsoap won't fail to startup if an initial connection attempt fails.

Fixes:

• LS-532,527: avoid freeze after errors in streaming threads or source
  initialization routines
• LS-542: race condition in playlist*() breaking randomness
• LS-489: double expiration lead to illegal queue length and freeze of
  request-based sources
• Avoid multiple simultaneous reloading in playlist*(),
  thanks to Fabio Costa for his help on this one!
• Pass charset information to icecast server to avoid encoding bugs
• LS-555: timeout for icecast connection attempts
• LS-559: permanent stop after disconnection on Ogg streams
• LS-565: efficient and crash-free error handling in input.http/harbor()
  when the input stream has an invalid number of channels
• LS-431: proper handling of duration in blank() avoids abusive empty tracks
• LS-556: rework conversion operators, optimizations used to be unsafe & broken
• LS-574: silent MIDI synthesis operators
• LS-396: drop*()'s types reflect that they don't support variable arities
• LS-442: allow comments not terminated by newline at end of file

New:

• on_error handler in output.icecast(), see above
• New msg param in %mp3 for marking frame headers, defaults to version string
• output.file(): new on_close parameter, may be used to write exact duration
• %mp3.vbr/abr for variable bitrate MP3, %mp3 is now a synonym of %mp3.cbr
• MP3 encoders now support ID3v2 tags
• input.http(): new "status" command
• LS-556: mux_mono() for adding a single audio channel into a stream
• video.add_text() using libgd (gd4o) for environments without X
  Dependency on graphics can be disabled (to work around erreneous detection)
• script language: add infix operator mod (patch by Fabio Costa)
• delay() now has an "initial" parameter
• LS-557: "server.timeout" setting can now be disabled by setting it to -1
• LS-532: source.init() for selective init with a way to handle errors,
  plus settings "clock.allow_streaming_errors" and "init.force_stat" (or
  --force-start on the command line) for easing dynamic uses of liquidsoap
  Enhancements:
• Panic crash to avoid frozen liquidsoap after duppy crashes
• Text-to-speech: festival and sox are now only runtime dependencies
• LS-475,516: better support for dynamic URL change in input.http()
• LS-484: display user-friendly error messages in interactive mode
• LS-308: use seconds internally in request sources, avoid overflow and
  display more user-friendly debug messages
• Cleanup visu.volume() and video.vis_volume()
• LS-573: replace " " by "_" in identifiers to make them valid in the server
• Script syntax: unary minus now usable without parenthesis after semicolon
• Two generic queues by default, to avoid deadlocks in advanced situations
• Documentation, build & install system, etc.

Liquidsoap 1.0.0 beta 3

• Feature: Added of_json to parse json data. Depends
  on json-wheel.

  through server/telnet command.
• Fix: dynlink detection in native mode with old
  versions of ocaml
