add multi-upload support

[robinvd]

Don't know if you already want to implement this, or if this is the best way. But here is my version for multi-upload.

I saw you just updated the repo making mine out of sync. If you want to merge this ill update it. and if you dont, well i had fun making this :).

to test: http://localhost:43110/152qbnvTwEDHoDSecNQhYoR6z78QVLpE4f

Just noticed that not all files are added to the db. All items read in the db and then write it again, overwriting each other

[Emeraude]

It looks interesting.
You should update it to make it compatible with the Emeraude/master branch.

[Emeraude]

This king of debug should be removed.

[Emeraude]

Track number should not be dismissed (it will be used later).

[Emeraude]

Did you manage to figure out why some the db is not correctly updated with your version ?

[Emeraude]

I think I got it. It's because calls to ZeroNet API are asynchronous, and variable i at line 129 is overwrited.

[robinvd]

That is the issue i first ran into, but line 135 uses the "do" which makes the variables "metadata, path, i" static to the inner part (not sure if clear enough). I think the problem is: In line 140 it reads the file contents.json, if all iteration read the file, change it and write it back. they only write their own modifications

[Emeraude]

Yes, that's probably true.

[robinvd]

Maybe its a good idea to only start uploading the next one when the first one is done. and keep the contents.json in mem while uploading.

[Emeraude]

We can upload all the files at the same time, but we have to update the data.json file only once.

[robinvd]

Maybe:

var toUpload = e.files.length

and at the end of the callback:

toUpload -= 1
if toUpload == 0
  writetofile
  playSong()

[Emeraude]

I'd be happy to merge this PR if you correct the bug with that piece of code above, and if you correct the conflicts with the Emeraude/master branch (it's only about the track hidden field, which is missing in your PR).

[robinvd]

Will do that, after my exams.

[Emeraude]

Are you still working on it?
