Save Playlist Automatically

Nevermind, it's already in TODO....

The item in the TODO list actually stands for exporting the playlist to m3u.

Pogo already saves the playlist when the signals SIGTERM or SIGINT are sent to it. I don't know which signal is sent to Pogo, when the OS shuts down, but I'm pretty sure it's first SIGTERM and then SIGKILL. If only the signal SIGKILL is sent, then nothing can be done, because this signal cannot be caught.

Can you try if Pogo saves your playlist on shutdown with the latest development code?

I tried and it doesn't save the playlist. To make this work, I think you will need to make it save the playlist everytime a music is added or deleted. Would this cause any performance issue?

See if you can reproduce this.

Maybe you could try to find out which signal Ubuntu sends on shutdown?

Saving the playlist everytime is not desirable, I think.

I tested SIGTERM and SIGKILL, in neither pogo saves the playlist. From what I found on the internet, Ubuntu sends SIGTERM then SIGKILL, so you could trap SIGTERM, using something like this: http://ubuntuforums.org/showthread.php?t=1436304

I made a video of my test:
https://dl.dropbox.com/u/10732001/signal.ogv
(9 is SIGKILL and 15 is SIGTERM)

This may be useful:

I hope this helps

Try this:
import signal

def handleSigTERM():
    atExit()

signal.signal(signal.SIGTERM, handleSigTERM)

but with the proper function. "atExit()" doesn't seem to be the function that saves the playslist (too lazy to search, plus is pretty late already).

Actually this code already exists in pogo.py

I'll try to reproduce the error over here first.

I made a mistake! I used kill -9 15 ID when I should have used kill 15 ID. SIGTERM will save the playlist and SIGKILL won't! My bad, sorry...

And is the playlist saved even at OS shutdown?

No, it isn't... it seems that OS Shutdown = SIGKILL

Yes, here too. My playlist is not saved at shutdown. Hmm, there doesn't seem to be a way to do it...

I noticed that not even Google Chrome can save anything at shutdown since if I turn off my pc with Chrome opened, when I open Chrome again it will say that it wasn't terminated correctly. Maybe Pogo could save the playlist from time to time, like every 3 minutes.

I like the idea. Let's put it on the wishlist.

I changed pogo.py to make it save every minute. http://dl.dropbox.com/u/10732001/pogo.py

I added this:

    def save():
        media.save( files, "~/.config/pogo/saved-playlist")
 return True

    gtk.timeout_add(60*1000, save)

I will test it a little.... really don't know if it is working properly, yet

No, it isn't.... here we go again.... when I have something, I return

I implemented this in trunk. Playlist is saved every 10 minutes for now.
