Rework MIME Type handling #227

Open jpfeuffer opened 5 years ago

jpfeuffer commented 5 years ago

There are some points to consider: 1) Add an "any" or "*" MIME type, so some nodes can accept any type 2) Maybe add missing mime types on the fly. (With a single extension of the newly found one, and a name like "unknown-$extension"

Also 3) FileListPorts should probably have a MIMETypeSet to allow mixed lists.

And what if mimetypes overlap, e.g. when multiple plugins include an extension in one of their mime types. Probably also not handled here.

So I found the best possibility is just to use the extension as is, if no mimetype is found. Makes more sense than failing IMHO. A perfect match should always be allowed, only a fallback should be to compare possible Mimetype agreement.
