The package ignored errors from net.Conn Set*Deadline in a few places.
Update the package to return these errors to the caller.
Ignore all other errors reported by errcheck. These errors are safe to
ignore because
- The function is making a best effort to cleanup while handling another
error.
- The function call is guaranteed to succeed.
- The error is ignored in a test.
Add WriteBufferPool to Dialer and Upgrader. This field specifies a pool
to use for write operations on a connection. Use of the pool can reduce
memory use when there is a modest write volume over a large number of
connections.
Use larger of hijacked buffer and buffer allocated for connection (if
any) as buffer for building handshake response. This decreases possible
allocations when building the handshake response.
Modify bufio reuse test to call Upgrade instead of the internal
newConnBRW. Move the test from conn_test.go to server_test.go because
it's a serer test.
Update newConn and newConnBRW:
- Move the bufio "hacks" from newConnBRW to separate functions and call
these functions directly from Upgrade.
- Rename newConn to newTestConn and move to conn_test.go. Shorten
argument list to common use case.
- Rename newConnBRW to newConn.
- Add pool code to newConn.
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.
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
}
