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 b0dc45572b Change default and add API for compression level 
Change the default compression level to 1. This level is faster and uses
less memory.

Add Conn.SetCompressionLevel API to allow applications to tune
compression on a per message basis.

Gary Burd 17634340a8 Update compression documentation 
Add "EXPERIMENTAL" to the compress section header.  This change is intended to draw more attention to the status of the feature as stated in the first sentence of the section.  This is not a change in the status.

Gary Burd 9fbf129ff2 Add Conn.[Set]CloseHandler 2016-11-02 13:04:59 -07:00
Gary Burd 80a0029a65 Improve write error handling 
- Do not fail NextWriter when close of previous writer fails.
- Replace closeSent field with mutex protected writeErr. Set writeErr on
  any error writing to underlying network connection. Check and return
  writeErr before attempting to write to network connection. Check
  writeErr in NextWriter so application can detect failed connection
  before attempting to write.
- Do not close underlying network connection on error.
- Move message writing state and method flushFrame from Conn to
  messageWriter. This makes error code paths (and the code in general)
  easier to understand.
- Add messageWriter field err to latch errors in messageWriter.

Bonus: Improve test coverage.

- Prevent developers from calling the Client.write method from outside
  of the writePump goroutine by removing the method. The code is now
  inlined in Client.writPump.

Gary Burd a87eae1d6f Add hooks to support RFC 7692 (per-message compression extension) 
Add newCompressionWriter and newDecompressionReader fields to Conn. When
not nil, these functions are used to create a compression/decompression
wrapper around an underlying message writer/reader.

Add code to set and check for RSV1 frame header bit.

Add functions compressNoContextTakeover and decompressNoContextTakeover
for creating no context takeover wrappers around an underlying message
writer/reader.

Work remaining:

- Add fields to Dialer and Upgrader for specifying compression options.
- Add compression negotiation to Dialer and Upgrader.
- Add function to enable/disable write compression:

    // EnableWriteCompression enables and disables write compression of
    // subsequent text and binary messages. This function is a noop if
    // compression was not negotiated with the peer.
    func (c *Conn) EnableWriteCompression(enable bool) {
            c.enableWriteCompression = enable
    }
