This has happened two mornings in a row now, approximately an hour or hour and a half after starting up in the morning. Every morning we have a bounce in place via cron for the RPC server that kicks off around 9AM. Now the last two mornings it's started doing that weird noise about 1-1.5 hours after starting up. That in itself isn't the weird part though, because generally a quick restart solves the issue. After the restart though, we end up in this weird loop of endlessly downloading songs. Here's a log excerpt:

It did the same thing yesterday as well. I left it off for a few minutes, restarted it, and everything seemed to go back to normal. It also did this for a couple minutes yesterday with DjPandora completely shut down, so I don't think it's anything on the web frontend causing it, but I'm willing to be wrong :)

so we always have a playlist queue of ~5, instead of the queue slowly counting down, refilling, repeat. this should be an easy addition

afaik, xmlrpclib (http://docs.python.org/library/xmlrpclib.html) only allows for basic http authentication. this is probably good enough for authenticating users.

any changes to implement this should go into rpc_server.py as much as is possible

when using playSound, i think if a bunch of sounds get played concurrently while music is playing, there'll be a rare error:

FMOD error! (11) The specified channel has been reused to play another sound. <ProtocolError for localhost:8123/RPC2: -1 >

should be pretty simple. once the function exists and is exposed to python, it should be used within the download lock (in Song.download) to set the length attribute on the song object, instead of having it get lazy-set when the song is first played

there's two playable format types, "mp3" and "mp3-hifi"

search pandora.py to find these strings. whether they're available or not comes directly from the playlist xml pandora responds with...it's in each song block. code needs to select hifi if it's available, otherwise regular mp3

humbug

"(2336) 2011-11-07 00:54:42,842 - <WebConnection 127.0.0.1:55848 "/m"> - ERROR -
peer closed connection" and similar messages occur on every instance of a new song being loaded. The end result is that the audio never plays. I have a feeling this is because I didn't feel like booting into linux and ran the script using the Windows version of python. It's version 2.7. Browsers tested include Firefox, Chrome, and IE.

usually happens when you've been playing for awhile and you try to like/dislike a song, the auth token has expired, so the code tries to re-auth, but for some reason never completes successfully, so it keeps retrying over and over, making us look like spammers :)

add as methods on PandoraServerProxy in rpc_server.py

should basically just use self.account.current_song.like(), self.account.current_station.next() (? can't remember if that exists), etc

here's the spec http://www.id3.org/id3v2.3.0

this should be done in its own branch

for both 32bit and 64bit, mac and linux, and install the correct ones based on some tests in setup.py. should only add another 1.5mb to the actual installation, and ~5mb to the package

After switching stations the station in song information does not change

seems to work fine when using python setup.py develop, but not if you do build, then install. module complains about not being able to find the xml files

After being paused for a while and being started again, we get an unsupported file type error from FMOD. Should I just expect to bounce or reauth in these situations, or do you have any ideas on how to better handle it?

a customer commandline tool to interface with the xmlrpc server. i think you can use the code module http://docs.python.org/library/code.html

700Mb after a few hours....maybe some objects aren't being released?

Upcoming songs are not updating after station change

@redsky17 found this, need to confirm

How do I adapt this to run on a already running webserver? I'm trying to upload it to my host but I'm getting a Internal Server Error.

Would it be possible to get a "get_volume" function? Not sure if that's kept anywhere on your end. If not, I can find a storage place for it on the front end, so that I can init the volume slider with the current volume level.
