Description Matt Wald 2005-08-20 12:28:44 UTC 
In response to standard commands such as mode, playlist, author, title, etc., 
CLI will return %3F and other data in the response intermittently (see 
below).  I can replicate this by typing the command directly into a telnet 
window, or through a polling program. This behavior occurs in both the Linux 
and Windows versions of Slimserver, with a Squeezebox 1.

Example:  00:04:20:05:5d:ae mode ?
Response: 00%3A04%3A20%3A05%3A5d%3Aae mode %3F00%3A04%3A20%3A05%3A5d%3Aae

Comment 1 KDF 2005-08-20 13:45:31 UTC 
Fred, is this the problem you've been discussing on the forum?
Comment 2 Fred 2005-08-20 14:27:17 UTC 
Yes. Will try to nail it now
Comment 3 Fred 2005-08-20 15:21:38 UTC 
KDF, Dan, help!!!

This is crazy. 

>CLI: Excuting command: 00:04:20:05:5d:ae mode ?
>Command.pm: Executing command 00:04:20:05:5d:ae: mode (?)

So the CLI parsed command OK and gave good params to Command::execute().

In command.pm, we have:

		} elsif ($p0 eq "mode") {
			if (!defined($p1) || $p1 eq "?") {
				$p1 = Slim::Player::Source::playmode($client);
			} else {
 				[...]
			}
		} elsif ...

and then the callcallback stuff which there isn't since the CLI do not use this execute parameter.
Then there is the executeCallback which calls the CLI (does not write the params) and modifyPlaylist in 
Player.pm which does not touch the params either (and immediately returns for the mode command).

And then we print the returnarray, and that gives:

>Command.pm:  Returning array: mode (?00:04:20:05:5d:ae)
which the CLI rightly returns as:
>CLI: 00... mode %3F00%3A04%3A20%3A05%3A5d%3Aae

I cannot figure how $p1 is assigned "?00:04:20:05:5d:ae". Other people see ?mode or ?playlist, so there 
is something very funky going on. And I can't reproduce that on Mac OS X, no matter how hard i try...

Can one of you try it on Windows or Linux, and maybe try a couple of debug lines to see where things 
go sour? Or maybe you have a brilliant idea...
Comment 4 KDF 2005-08-20 18:11:02 UTC 
no luck getting much wrong stuff back here.  tried 6.1.x and 6.2 on linux.  I
can get %3f by using duration ? when there is no playlist.  I get the following

Comment 5 Fred 2005-08-21 04:55:51 UTC 
Thanks KDF. If there is no playlist, the %3F is normal: it's just the input "?" url-encoded. The server is 
returning your command intact, it was not processed (since there is no playlist). Odd maybe, but the 
"defined" behaviour...

Matt, I have added a bunch of additional debug messages to the log. They will appear in the nightly tonite 
(4015 or bigger).  May I ask that you try "mode ?" and "playlist index ?" on your system again with 
d_command and d_cli on and post the logs again? This one is giving us some trouble...
Comment 6 Matt Wald 2005-08-21 11:27:53 UTC 
Will do, and sorry if I'm not explaining it very well.  A couple of other 
things that might not relate but I'll tell you about it anyway in case it does:

1) My polling program sends update queries to the CLI pretty rapidly - is it 
possible that the address being appended sometimes at the end of the response 
(it's not alway an address by the way) is actually the address that is being 
sent for a new command?  Some sort of buffer overrun or something?
2) Also, I've noticed that when the CLI polling program is running that it 
will cause songs to be skipped in the playlist and start back at index 0.

Will send you new logs.
Comment 7 Fred 2005-08-21 12:44:47 UTC 
For the rapid CLI firing skipping songs, yes it is possible. The same happens on the web interface *except* 
with the refreshing and stuff you never have the chance to go fast enough...

As for the rapid CLI firing, that's why I wanted to see the program *BUT* you tell me you also get that with 
Telnet... and there you can't go very fast.

I will nevertheless try to overload the CLI see what happens...
Comment 8 Matt Wald 2005-08-21 16:03:10 UTC 
Fred, I've confirmed today that when I turn off the CLI polling program the 
tracks that used to skip to index 0 in the playlist no longer do.  Also, in 
thinking more about how I recreated this through telnet, I realized that the 
polling program was probably still running on another device at the time I 
entered the command through telnet.  I'm now playing around with varying the 
time delay for sending commands ...
Comment 9 Fred 2005-08-21 17:06:37 UTC 
Well, please try that, it might help. In my programs, I do tend to wait for the server reply before sending a 
new command, but that would require extensive changes in yours. In that configuration it works :-)

Nevertheless, it should work no matter how quick you are sending things. I found something strange in 
the parsing that I fixed, but I am not sure it applies since from the log below it seems the parsing is OK...

Let us try again with the latest nightly and contine from there.
Comment 10 Blackketter Dean 2005-08-21 17:30:55 UTC 
Fred, Matt:  I'm not quite following here.  Is this still an issue?  If so, should we consider it for 6.2 (beta 
end of this month, final end of Sept.)
Comment 11 Fred 2005-08-21 17:33:05 UTC 
6.2 for sure, I want that fixed in the 6.1.x nightlies before that.
Comment 12 Matt Wald 2005-08-22 05:23:15 UTC 
Well it looks to me like 4030 may have cured the problem.  I can't recreate 
the behavior on two of the tracks that consistently skipped, and I can't get 
any responses with ? even when the polling program is at its original speed. 
(Incidentally, the CLI responses are faster now, which is great.) I'll keep 
testing to make sure but it looks like you got it.  Great job!  And thanks 
alot.
