If a song is not within the music directory ("file:///..."), it has no
"parent directory". The archive code nonetheless dereferences the
parent pointer, causing a segmentation fault. Check parent!=NULL.
One of the previous patches made MPD consume 100% CPU in a busy wait:
when the music_pipe was full, it did not wait (with notify_wait()) for
free chunks, because a variable has a different meaning now. Always
pass "true" as the "wait" parameter.
Some plugins used the APE or ID3 tag loader as a fallback when their
own methods of loading tags did not work. Move this code out of all
decoder plugins, into song_file_update().
This new API gives the caller a writable buffer to the music pipe
chunk. This may allow the caller to eliminate several buffer copies,
because it may manipulate the returned buffer, until it calls
music_pipe_expand().
When libvorbis knows that a song is seekable, it seeks around like
crazy in the file before starting to decode it. This is very
expensive on remote HTTP resources, and delays MPD for 10 or 20
seconds.
This patch disables seeking on remote songs, because the advantages of
quickly playing a song seem to weigh more than the theoretical ability
of seeking for most MPD users. If users feel this feature is needed,
we will make a configuration option for that.
getBoolConfigParam() returns an int. It is not possible to check for
CONF_BOOL_UNSET after it has been assigned to a bool; use a temporary
int value for that.
Calling input_curl_select() after EOF has been reached causes an
assertion failure. This can happen if the HTTP response is empty.
Check c->eof before calling input_curl_select().
Path names in the directory and song structs are always encoded in
UTF-8. Don't use strcmp(), it cannot handle UTF-8 characters
properly. Use GLib's UTF-8 aware g_utf8_collate() function for that.
I was having problems with shoutcast stream outputs before applying
the attached patch, which enlarges the shoutcast output
buffer. Ideally, this should be configurable, but this resolves the
issue for my needs.
vorbis_parse_comment() should be a function which converts one comment
to a tag item. It should do everything required to do the conversion,
including looping over all possible tag types.
mpd uses some additional files to work, such as pid_file, state_file,
db_file, etc. when running mpd as non-root user, it is often that those
files end in ~/.mpd
in that case, we end up with 2 entries in a user's home, .mpdconf and
.mpd - which clutters homedirs.
this patch allows ~/.mpd/mpd.conf as an alternative to ~/.mpdconf,
allowing for a cleaner homedir
If a tag value is an empty string, the space after the colon was
removed by g_strchomp(). Fix this by removing the space check and
using g_strchug() on the return value.
The matchesAnMpdTagItemKey() API becomes more powerful and flexible if
the return value is the value pointer instead of a boolean. It also
removes (invalid and dangerous) assumptions about the string from its
caller.
When a song file is deleted during database update, all pointers to it
must be removed from the playlist. The "for" loop in
deleteASongFromPlaylist() did not deal with multiple copies of the
deleted song properly, and left instances of the (to-be-invalidated)
pointer in. Fix this by reversing the loop.
Added TAG_ITEM_ALBUM_ARTIST.
With this patch, MPD should be able to read the (inofficial)
"ALBUMARTIST" Vorbis comment. Implementations in other decoder
plugins will follow soon.
matchesAnMpdTagItemKey() broke when two tag items had the same prefix,
because it did not check if the tag name ended after the prefix. Add
a check for the colon and the space after the tag name.
If http_proxy_{host, port, user, password} are provided in mpd.conf
they are not passed on to libcurl. As a result mpd cannot stream from
behind an http proxy.
The attached patch `http_proxy.patch` makes the relevant calls to
curl_easy_setopt(...) for all proxy configuration parameters, but is
only tested for host and port.
MPD's shuffling algorithm was not implemented well: it considers songs
which were already swapped, making it somewhat non-random.
Fix the Fisher-Yates shuffle algorithm by passing the proper bounds to
the PRNG.
When decoder_run_song() (decoder_thread.c) waits for the input stream
to become ready, it did that in a busy loop. Add a select() call to
input_curl_buffer() during connect/handshake (i.e. before the first
chunk of body data was received), to let the CPU relax.
MPD will (optionall) use sqlite databases in the future. Add a
configure option to enable that. There is no code yet to really use
sqlite, so the practical use of this patch is limited.
This patch tryes to introduce pluggable mixer (struct mixer_plugin) along with some basic infrastructure (mixer_* functions). Instance of mixer (struct mixer) is used in
alsa and oss output plugin
Loosely based on a patch provided by lesion in bug #1766. The playlistinfo
command can now retrieve ranges of the playlist. The new argument indicates
which entry is the last one that will be displayed. The number of displayed
entries may be smaller than expected if the end of the playlist is reached.
Previous usage:
playlistinfo [start]
New usage:
playlistinfo [start[:end]]
This library allocates temporary buffers for storing PCM conversion
results. It should replace all those "static" buffer variables which
are racy and never freed.
