Gary Burd 77f110791c Improve mask performance 2016-10-21 11:11:39 -07:00
Cyrus Katrak c09b72d2ee per message compression; only no context modes 2016-10-14 12:08:39 -07:00
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
    }

Tarmigan Casebolt ae46df13e9 Fix Read() to return errUnexpectedEOF when EOF is received before all bytes in the frame have been read 2016-04-24 22:30:05 -07:00
Gary Burd 0e2713e645 Address common gotchas with package 
Update documentation to explicitly state that applications must break out of a
read loop on error.

Detect application read loops spinning on a failed connection and panic.

Detect concurrent writes and panic. The detection is best-effort.

Update documentation to state that connections respond to close frames.

Gary Burd 47f93dfaed Improve errors. 
- Use new closeError type for reporting close frames to the application.
- Use closeError with code 1006 when the peer closes connection without
  sending a close frame. The error io.ErrUnexpectedEOF was used
  previously. This change helps developers distinguish abnormal closure
  and an unexpected EOF in the JSON parser.

Gary Burd 10afcadf69 Cleanup EOF handling. 
- Modify data message reader to return io.ErrUnexpectedEOF if a close
  message is received before the final frame of the message.
- Modify NextReader to return io.ErrUnexpectedEOF if underlying
  connection returns io.EOF before a close message.
