Details

This bug occurs when playing back a file and choosing to delete it from the WPS context menu while it is still playing.

If a trackchange occurs between choosing a file for deletion and actually pressing the 'Yes' option, the *new* currently playing file is deleted, rather than the one originally selected for deletion.

For example using the following playlist:
a.mp3
b.mp3
c.mp3
d.mp3

If b.mp3 is playing and a few seconds before the track ends, the user selects [context menu] > Delete

The screeen displays:

Delete?
b.mp3

SELECT = Yes
Any Other = No

Wait until c.mp3 commences playback, then press SELECT

The screeen displays:

Deleted
c.mp3

I thought we didnt allow the delete option in the wps context menu because nasty things happen if you try deleting a file while its not fully buffered, and this...
should the option be removed?

Personally I find it a very useful function whilst listening to podcasts etc. and I would not like to see it removed, especially as it was committed by a certain jdgordon ;-) http://www.rockbox.org/tracker/task/7437

However, unless the method by which the code determines the target file cannot be fixed, then maybe it should, as it is certainly not the behaviour that a user would expect and it will occur at exactly the time when a user is most likely to use the functionality i.e., at the end of a track.

Oh yes!

Thanks Steve, that patch works perfectly for me. Is it able to be commited?

My untrained eye doesn't see anything in the code or the functionality that could upset anyone...
