Response change between 0.21.6 and current

[keithg]

I am trying to continue development of an older UI to MPD and have noticed that as of sometime after 0.21.6 the responses from the MPD daemon on the socket have changed. What I noticed is the existing UI php/js chokes when it tries to parse the playlist as the first line is a blank probably with a new line. I was able to get it to parse the playlist by discarding the first line then rendering. I am not a PHP or JS expert, so I am muddling through. I am trying to get the AlbumArtist to sort and parse correctly. This code used to work with an older version of MPD, 0.20.x, and I am trying to update it all. Has there been a change in the output format?

Regards,

Keith

Be more specific. What has changed in your opinion?

Well, what I see is that some responses have a space as the first line. My install is on Arch on a RPi

The installed version of MPD is 0.21.18:

Code: Select all

# pacman -Q | grep mpd
libmpdclient 2.17-1
mpd 0.21.18-1
And the response from MPD is:
root@livingrune(rw):~# mpd -V
Music Player Daemon 0.21.18 (0.21.18)

yet on the cli is reports 0.21.11 (strange) and I get no space on "playlist":

Code: Select all

# telnet 127.0.0.1 6600
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
OK MPD 0.21.11

when I list albums, though, I get a space (first response is blank) which is that the idtag is missing an artist:

Code: Select all

list "album"
Album:
Album: (The Best Of) New Order
Album: ...Best II
...

Same for AlbumArtist

Code: Select all

list "albumartist"
AlbumArtist:
AlbumArtist: 'Til Tuesday
AlbumArtist: 2CELLOS
AlbumArtist: Adrian Belew
AlbumArtist: Aimee Mann

...

This is via telnet to the port and it looks fine. When I try it with 0.20.20, I get the same thing. My code, though, is using the socket and the javascript is complaining that the first character is a blank. I am re-working the code to deal with this, but it is a change. How can I query the port the same way?

please ignore this. I just checked against 0.20.20 and it seems to behave identically. It must be some other upgrade that has hosed my UI.

This means that there is at least one song without the specified tag.
