fuzzybear3965 1d375d5a0d distinguish Upgrader.Upgrade from Upgrade 2017-07-07 14:47:14 -04:00
Gary Burd b258b4fadb Use bufio.Writer returned from hijack in upgrade 
Reuse the buffer backing the bufio.Writer returned from hijack if that
buffer is large enough to be generally useful and
Upgrader.WriteBufferSize == 0.

Update the logic for reusing bufio.Reader returned from hijack to match
the logic for bufio.Reader:  The buffer backing the reader must be
sufficiently large to be generally useful and Upgrader.ReadBufferSize ==
0.

Improve the documentation for ReadBufferSize and WriterBufferSize in
Dialer and Upgrader.

Gary Burd 286b5c9371 Use bufio.Reader returned from hijack in upgrade 
Use the bufio.Reader returned from hijack if the reader's buffer size is
equal to the buffer size specified in Upgrader.ReadBufferSize.

Gary Burd 0674c7c796 Improve upgrade error messages 
Upgrade typically fails because the request is not a handshake, not
because the handshake is malformed. To help developers diagnose the
common case, state explicitly that the request is not a handshake in
error messages.

To help diagnose malformed requests, capitalize and 'quote' header names
in error messages.

Gary Burd 567453a710 Require GET in Upgrader.Upgrade. 
Return error if the request method is not GET.

Remove all request method tests from the examples.

Gary Burd ab5b3a61f5 Improve server error messages 
Update the error messages for missing 'Connection: upgrade' and
'Upgrade: websocket' tokens to indicate that the header might not be
present. The previous error message implied that the header is present,
but has the wrong value. This leads to some confusion for those
debugging connection problems.

Gary Burd 0f32413e5e Relax default origin test. 
Update the default origin test to treat no origin specified as OK. If
the client can create a request without the origin set, then the client
can also create a request with an arbitrary origin.

Gary Burd df94ef6daa Various improvements to Upgrader. 
- Revert back to using Subprotocols []string. The protocol negotiation
  using Subprotocols should meet the needs of most applications.
  Applications are not locked into using this negotiation. An
  application can pick a protocol some other way and specify the
  protocol using the Sec-Websocket-Protocol response header.
- Parse the origin using url.Parse. This is the correct function to use
  when parsing a full URL.
- Improve comments.
