HTTP Server Graceful Shutdown

HTTP Server Graceful Shutdown

+ +

+ The HTTP Server now has support for graceful shutdown using the new + Server.Shutdown + method. The related and more abrupt + Server.Close + is also new. +

Server changes:

+
    +
  • The server now supports graceful shutdown support, mentioned above.
    • + +
  • + The Server now + has new configuration options + ReadHeaderTimeout and IdleTimeout. + The previously ill-defined WriteTimeout is now + documented. +
    • + +
  • + FileServer + and + ServeContent + now support HTTP If-Match conditional requests, + in addition to the previous If-None-Match + support. +
    • + +
  • + The server now logs bad requests. +
    • +
+

- TODO -

+ There are several additions to what a server's Handler can do: +

+ +
    +
  • + The Context + returned + by Request.Context + is canceled if the underlying net.Conn + closes. For instance, if the user closes their browser in the + middle of a slow request, the Handler can now + detect that the user is gone. This complements the + existing CloseNotifier + support. +
    • + +
  • There is now a second way to serve trailers + for when the trailer name is not known before the headers are + written (via a call to + to ResponseWriter.WriteHeader). The old way + continues to work, but when the trailer is only known after the + header has been written, see the + new TrailerPrefix.
    • + +
  • + A Handler now has a supported mechanism to abort a + response: panicking with + ErrAbortHandler. +
    • + +
  • + There is now a supported mechanism to test whether a + ResponseWriter has been hijacked: Write zero bytes to it. + While this previously returned + ErrHijacked, now + it also does so without spamming the server's error log. +
    • + +
+ +

Client & Transport changes:

+
    +
  • + The Client now copies request headers on redirect. +
    • + +
  • + The Transport now supports international domain names. +
    • + +
  • + The Client now supports 307 and 308 redirects. + If the redirect involves re-sending the request body, + the request must have the new + Request.GetBody + field defined. + NewRequest + sets Request.GetBody automatically for common + body types. +
    • + +
  • + The Transport now rejects requests for URLs with + ports containing non-digit characters. +
    • + +
  • + The Transport will now retry non-idempotent + requests if no bytes were written before a network failure. +
    • + +
  • + The + new Transport.ProxyConnectHeader + allows configuration of header values to send to a proxy + during a CONNECT request. +
    • + +
  • + The DefaultTransport.Dialer + now enables DualStack ("Happy Eyeballs") support, + to use IPv4 as a backup if it looks like IPv6 might be + failing. +
