5.2 Connection Manager
| (require web-server/private/connection-manager) | |
| package: web-server-lib | |
This module provides functionality for managing pairs of
input and output ports. We have plans to allow a number of different strategies
for doing this.
struct
(struct connection (timer i-port o-port custodian close?) #:extra-constructor-name make-connection) timer : timer? i-port : input-port? o-port : output-port? custodian : custodian? close? : boolean?
A connection is a pair of ports (i-port and o-port) that is
ready to close after the current job if close? is #t. Resources
associated with the connection should be allocated under custodian.
The connection will last until timer triggers.
procedure
Runs the connection manager (now just the timer manager).
procedure
(new-connection timeout i-port o-port cust close?) → connection? timeout : number? i-port : input-port? o-port : output-port? cust : custodian? close? : boolean?
Constructs a connection with a timer with a trigger of timeout that calls
kill-connection!.
procedure
(kill-connection! c) → void
c : connection?
Closes the ports associated with c, kills the timer, and shuts down
the custodian.
procedure
(adjust-connection-timeout! c t) → void
c : connection? t : number?
