Last.FM Rework and Auto DJ mode (1 Viewer)

[jameson_uk]

I will try and yes it's when 'null' is parsed that the crash occurs

I know you are not busy so if you do want to spend some time you could check for regression here

Using pre log4net code if you passed a null to Log.Error(Exception ex) did it fail like it does now or is this regression?

I fixed it by replacing in line 286 here : Log.Error(ex.InnerException); to Log.Error(ex.Message);
Now error is logged but no crash anymore.
Don't know if it's the right way to do lol

Seb could you try

		if (ex.LastFMError != LastFMException.LastFMErrorCode.UnknownError)
		{
		  Log.Error("Last.fm error when announcing now playing track: {0} - {1}",currentSong.Artist, currentSong.Title);
		  Log.Error(ex.Message);
		}
		else
		{
		  Log.Error("Exception when updating now playing track on last.fm");
		  Log.Error(ex.InnerException);
		}

Instead?

Also are you able to see why this is a problem? Can you debug as is to see if ex.innerexception is actually set? If not I am guessing that the logging does not handle a null being passed to it? (but did previously ??)

Also I did notice a bug that since last commit AutoDJ will not work unless the announce option is ticked but I will fix that when I am next at a dev machine

It's working (about log error now with your change)
I did break AutoDJ then

I'm really starting to get lost with the bugs... They seem to popup without changes being done on the specific files?!?

I produce the issue if i disable lastfm Radio plugin in MP config

I'm not sure to see/know how to do that

I'm not sure to see/know how to do that

Could you checkout and test 1.3 Final code with old logger and just get some code to do the same (something like)

var ex = new Exception();
Log.Error(ex.InnerException);

Probably will be the same and probably should be like this but just want to be sure this is still working as it did before.

I have add your line in videoplayer code
And mp didn't crash and i can confirm that we have the same 'null' value

If my test is OK, so it's clearly a regression.
The diff between 1.3Final and your branch is that music start.

I will going to do another test in another part of code

 

[Sebastiii]

I don't know what to say

If i add the same code on your branch to create the issue in videoplayer, it's ok MP didn't crash but when it comes from music it crash.

Almost perfect Mike, but the new option 'Allow different versions of the same track' seems broken. I've seen a lot of similar songs again in my playlist.

Hi,

I have push some commit in branch, can you see if it's ok, i have commit your change about null value and also prevent to announce track for URL stream.
When i have tested regression about null value in other place than music, MP didn't crash.

So best you can try by yourself when back from your work trip

Thanks

Ps : Like HomeY said, it seems to work fine but i have also some same track in log lol
