wp_insert_post_empty_content filter issues with auto-drafts and/or fix auto-draft duplicates

I have explained the issue at

The 'wp_insert_post_empty_content' filter can have adverse effects on getting the draft for New Posts (new-post.php)
resulting in numerous PHP Noticesand failure to get the auto-draft record properly.

My suggestion for an intermediate fix would be to replace:

        if ( apply_filters( 'wp_insert_post_empty_content', $maybe_empty, $postarr ) ) {
		if ( $wp_error )
			return new WP_Error( 'empty_content', __( 'Content, title, and excerpt are empty.' ) );
			return 0;


	if ( $id = apply_filters( 'wp_insert_post_empty_content', $maybe_empty, $postarr ) ) {
		if ( $wp_error )
			return new WP_Error( 'empty_content', __( 'Content, title, and excerpt are empty.' ) );
			return $id;

That way we can use the filter to prevent duplicates instead of having to resort to extending the db class.

Though ideally a native method to prevent auto-draft duplicates (along the same lines of my code) in wp_insert_post seems best.

I don't know who came up with the cleanup later idea, but it's far from an ideal practice, and as per previous tickets, doesn't always work.

I'd think we'd probably create issues with developers expecting a return of 0 here. @dd32: Would you mind weighing in here?

Changing the return values is going to break someones plugin, returning the values from the filter is going to certainly break someones plugin (Especially as the current use-case would probably be to return true/false).

It seems like the original aim of the ticket, to be able to prevent duplicates, should probably be achieved through filters higher in the stack somewhere
