Detailed Description

SimulatedDelayFetcher lets one configure various per-host delays, and will make hardcoded replies according to those replies. This exists to help run simulations of server behavior with sites of widely various speeds.

Constructor & Destructor Documentation

net_instaweb::SimulatedDelayFetcher::SimulatedDelayFetcher	(	ThreadSystem *	thread_system,
		Timer *	timer,
		Scheduler *	scheduler,
		MessageHandler *	handler,
		FileSystem *	file_system,
		StringPiece	delay_map_path,
		StringPiece	request_log_path,
		int	request_log_flush_frequency
	)

delay_map_path is the path to the file describing the delays for each host The format is: foo.com=4;bar.com=42;baz.com=43; (line breaks are permitted) The delays are in milliseconds.

request_log_path will be used to log when each request was received. (Not when it was served).

Member Function Documentation

virtual void net_instaweb::SimulatedDelayFetcher::Fetch ( const GoogleString &  url, MessageHandler *  message_handler, AsyncFetch *  fetch  )

virtual

Asynchronously fetch a URL, set the response headers and stream the contents to fetch and call fetch->Done() when the fetch finishes.

There is an unchecked contract that response_headers are set before the response_writer or callback are used. Caution, several implementations do not satisfy this contract (but should).

Todo:

TODO(sligocki): GoogleString -> GoogleUrl or at least StringPiece.

TODO(sligocki): Include the URL in the fetch, like the request headers.

Implements net_instaweb::UrlAsyncFetcher.
