- support HTTP/1.1 (no HTTP/1.0 needed)
- urls without / at the end (and %xx codes)
- etags using sha1sum
- if no index.html: return 404
- only GET support
- persistence and timeouts and 'connection: close' from both sides.
- concurrency with pipelining
implementation:
implemented in python using select. testing using 'unittest'.
asyncserver.py contains the basic asynchronous server implementation;
clients are stored in a list, and the event loop calls select() with a list of their sockets. Then, the clients are notified if there are any readable/writable/etc sockets that they own. The client connection class that is used can be specified when making the Server object.
server.py builds on it to implement a http server, with HTTPClient implementing the basic HTTP server, and HTTPDirClient implementing the static file server.
./run_tests.sh port requires the server to be active at the same port, it won't start it.
difficulties:
Testing took more time than desired, I wasn't sure if I was allowed to use the standard http library (or if it supports the neccesary tests without too much trouble), so I implemented some client functions.
