Threadless execution using coroutines (#134) * Workers need not register/unregister sock for every loop * No need of explicit socket.settimeout(0) which is same as socket.setblocking(False) * Remove settimeout assertion * Only store sender side of Pipe(). Also ensure both end of the Pipe() are closed on shutdown * Make now global. Also we seem to be using datetime.utcnow and time.time for similar purposes * Use time.time throughout. Remove incomplete test_cache_responses_plugin to avoid resource leak in tests * Remove unused * Wrap selector register/unregister within a context manager * Refactor in preparation of threadless request handling * MyPy generator fix * Add --threadless flag * Internally call them acceptors * Internally use acceptors * Add Threadless class. Also no need to pass family over pipe to acceptors. * Make threadless work for a single client :) * Threadless is soon be our default * Close client queue * Use context manager for register/unregister * Fix Acceptor tests broken after refactoring * Use asyncio tasks to invoke ProtocolHandle.handle_events This gives all client threads a chance to respond without waiting for other handlers to return. * Explicitly initialize event loop per Threadless process * Mypy fixes * Add ThreadlessWork abstract class implemented by ProtocolHandler * Add benchmark.py Avoid TIME_WAIT by properly shutting down the connection. * Add benchmark.py as part of testing workflow * When e2e encryption is enabled, unwrap socket before shutdown to ensure CLOSED state * MyPy fixes, Union should have worked, but likely unwrap is not part of socket.socket hence * Unwrap if wrapped before shutdown * Unwrap if wrapped before shutdown * socket.SHUT_RDWR will cause leaks * MyPy * Add instructions for monitor.sh * Avoid recursive exception in new_socket_connection and only invoke plugins/shutdown if server connection was initialized * Add Fast & Scalable section * Update internal classes section * Dont print out local dir path in help text :) * Refactor * Fix a bug where response parser for HTTP only requests was reused for pipelined requests resulting in a hang * Add chrome_with_proxy.sh helper script * Handle OSError during client.flush which can happen due to invalid protocol type for socket error * Remove redundant e * Add classmethods to quickly construct a parser object * Don't raise from TcpConnection abstract class. This allows both client/socket side of communication to handle exceptions as necessary. We might refactor this again later to remove redundant code :) * Disable response parsing when TLS interception is enabled. See issue #127 * remove unused imports * Within webserver parse pipelined requests only if we have a route * Add ShortLinkPlugin plugin * Add more shortlinks * Add ShortLinkPlugin to README.md * Add path forwarding too instead of leaving as excercise ;) * Add shortlink to TOC * Ensure no socket leaks * Ensure no leaks * Naming * Default number of clients 1 * Avoid shortlinking localhost * Stress more
