serve_file for any file object

Question

In cherrypy.lib.static.py there is a method:

  serve_file(path, content_type=None, disposition=None, name=None)

where the argument "path" must be a real file (absolute path). Is there something similar to serve any Python file object?

Answer 1

From studying http://www.cherrypy.org/browser/trunk/cherrypy/lib/static.py I'd have to say, no: the serve_file function is "monolithic", and does its own bodyfile = open(path, 'rb'), nor does there seem to be any alternative way. Pity, as it would be easy to refactor the function and add another e.g. serve_open_file to cover your case, having both delegate to an internal function for the "hard" logic such as multipart/byteranges serving. May be worth your while to open a feature request ("enhancement ticket") on cherrypy.org -- may not be a killer feature but I can see use cases, and implementing it wouldn't be hard for the cherrypy people (visit their site and follow the instructions on the page to "log in" to it).
