New submission from Glenn Linderman <v+pyt...@g.nevcal.com>:
The idea inspired by the email exchange below is basically in three parts: 1. investigate the various popular web server frameworks, to determine what parts of http.server they depend on. For example, bottle.py depends only on BaseHTTPRequestHandler and HTTPServer, which is less than half the code in http.server. Because of the deficiencies in the remaining parts, it seems unlikely that other frameworks use much more. 2. Trim http.server to those useful parts, removing the the rest from stdlib. Many of the "enhanced features" of http.server are such minimal enhancements that they are feature-poor and out-of-date with respect to current web server standards. The novice user is likely to be enticed into a swamp of missing capability when attempting to use them, as I was. It would take significant work to implement true CGI together with SSL on forking OSes; it took me significant work to implement true CGI together with SSL on Windows (non-forking). I gave up trying to do it on Linux, and switched to bottle. 3. Enhance what is left of http.server to support SSL and threading, so that the web frameworks that use http.server as a test server can at least offer those capabilities as well. It isn't too hard to add those things for bottle.py, but it would be nicer if users didn't have to google for the blog posts that show how, and reimplement it (most of the blog posts are somewhat dated).
