2012-01-30Move max_connections check directly inside cowboy_listenerLoïc Hoguin
This is a big change in the internal cowboy API. This should not have any impact on existing applications as only the acceptor is expected to use these API calls. The function cowboy_listener:wait/3 has been removed. max_connections checking now occurs directly in cowboy_listener:add_connection/3. If the pool is full and the acceptor has to wait, then it doesn't return, waiting for a free space to be available. To accomodate these changes, it is now cowboy_listener that will inform the new connection that it is ready by sending {shoot, self()}. This should be a great improvement to the latency of responses as there is one less message to wait for before the request process can do its work. Overall the performance under heavy load should also be improved as we greatly reduce the number of messages sent between the acceptor and the listener process.
2011-12-15Add cowboy:accept_ack/1 for a cleaner handling of the shoot messageLoïc Hoguin
2011-08-10Give the ListenerPid to the protocol on startupLoïc Hoguin
Also sends a message 'shoot' that can be received by the protocol to make sure Cowboy has had enough time to fully initialize the socket. This message should be received before any socket-related operations are performed. WebSocket request connections are now moved from the pool 'default' to the pool 'websocket', meaning we can have a lot of running WebSockets despite having a low 'max_connections' setting.
2011-08-10Introduce cowboy_listener for managing a listenerLoïc Hoguin
Currently only supports limiting the maximum number of connections by managing connection pools.
2011-07-06Add documentation for the public interface.Loïc Hoguin
This is probably not perfect yet but it should be better than nothing. We'll improve things with feedback received from the many users.
2011-05-25Refresh the type specifications.Loïc Hoguin
Following discussions on #erlounge. Also fixes compilation in R14B03 and fixes a few underspecs dialyzer warnings.
2011-05-09Add a max_connections transport option.Loïc Hoguin
Limits the number of parallel requests processed at once. Waiting requests are kept in the accept queue. The limit is not explicitly observed, but it should be around the given value at any time. Defaults to 1024. Thanks to ostinelli's benchmark to point out the issue hopefully solved by this and the previous commit.
2011-04-18Remove the include/types.hrl file.Loïc Hoguin
2011-04-18Use the inet:socket() type instead of the user-defined one.Loïc Hoguin
2011-04-16Add an accept timeout for code reloading.Loïc Hoguin
Thought it was already there, but I guess not. Anyway it's here now so everything is back to normal. ;)
2011-04-02Anonymize and improve the cowboy supervision tree.Loïc Hoguin
* Cowboy isn't an OTP application anymore; just a supervisor. * All processes started by Cowboy are now anonymous. * All processes related to a listener are now part of its supervision tree.
2011-03-17Don't crash on Transport:controlling_process return in the acceptor.Loïc Hoguin
Crashes can happen if we close the connection too fast, leading to controlling_process returning {error, closed} instead of ok. This can happen when we receive bad requests, reply with 404 Not Found and more. Simply do not match the return value of controlling_process to avoid this.
