* client: Support read timeouts on receive & close.Andrew Whatson2023-05-072-22/+82
| | | | | | | | | | | | * web/socket/client.scm (close-websocket): Add timeout parameter. Call read-close-frame with timeout. (websocket-receive): Add timeout parameter. Call read-data-frame with timeout. Don't close the websocket on timeout. * web/socket/frame.scm (port-readable?, port-writable?, frame-reader): New helper procedures. (read-close-frame): New procedure. (read-data-frame): Add timeout parameter. Use frame-reader to support a composed read timeout.
* client: Handle control frames in websocket-receive.Andrew Whatson2023-04-213-42/+64
| | | | | | | | | * web/socket/frame.scm (read-data-frame): New procedure, extracted from serve-client. * web/socket/client.scm (websocket-receive): Call read-data-frame. Clean up the websocket if the connection was closed. * web/socket/server.scm (serve-client): Call read-data-frame. Flush the port after writing the handshake response.
* client: Support secure websockets.Andrew Whatson2023-04-192-21/+27
| | | | | | | | | * web/socket/client.scm (make-client-socket): Add verify-certificate? parameter. Call open-socket-for-uri to create the socket. (handshake): Flush the port after writing the request. (make-websocket): Add #:verify-certificate? parameter. * web/socket/frame.scm (write-frame): Flush the port after writing the frame.
* Use inet-pton instead of inet-aton.Jan (janneke) Nieuwenhuizen2021-03-181-1/+3
| | | | | * web/socket/server.scm (make-server-socket): Add #:family parameter and use it for inet-pton.
