Added the "fd_util" library, which attempts to use the new thread-safe
Linux system calls pipe2(), accept4() and the options O_CLOEXEC,
SOCK_CLOEXEC. Without these, it falls back to FD_CLOEXEC, which is
not thread safe.
This is particularly important for the "pipe" output plugin (and
others, such as JACK/PulseAudio), because we were heavily leaking file
descriptors to child processes.
When an output's enable() method has failed, and playback starts,
retry to enable it. Without this, the user may be confused, because
he sees the device is "enabled" but cannot use it, and currently there
is no error message in the log.
Moved the global input stream opener to decoder_run_stream().
decoder_run_file() now opens the input stream each time a plugin
provides a stream decoder method.
Same as the previous patch: create up to 16 configured source ports.
The plugin tries to do its best at guessing the right combination for
the given input file, the number of source and destination ports.
This patch allows the client to load a playlist file from the playlist
directory with a plugin. This can be used with the "load" command,
but the client has to pass the file name including the suffix. We
will probably use the music directory in the future, to support
playlist files inside the music directory.
If one plugin has failed to open the playlist, it may have consumed a
part of the stream already. This may lead to a failure in all
following plugins. Fix: rewind the stream before each open() call.
Implement the methods enable() and disable(). Bind the HTTP port in
the enable() method, but reject all incoming connections until the
output is opened.
After playback has stopped, the ring buffers may still contain
samples. These will be played when playback is started the next
time. We should clear the buffers each time.
jack_client_new() is deprecated. This requires libjack 0.100
(released nearly 5 years ago). We havn't been testing older libjack
versions anyway.
As a side effect, there is the new option "autostart".
When a song's tags could not be loaded during database update, log
this as a debug message. Same for a song being removed because its
updated tag could not be read.
Store a list of supported tag items in the database. When loading a
database which does not have a matching list, we must rescan in order
to get the missing information.
When the decoder finishes the "queued" song very quickly (before the
"current" song finishes playing), an assertion in do_play() fails
because it thinks that it should start decoding the queued song,
although that has in fact just finished.
