crypto/tls: buffer handshake messages. This change causes TLS handshake messages to be buffered and written in a single Write to the underlying net.Conn. There are two reasons to want to do this: Firstly, it's slightly preferable to do this in order to save sending several, small packets over the network where a single one will do. Secondly, since 37c28759ca46cf381a466e32168a793165d9c9e9 errors from Write have been returned from a handshake. This means that, if a peer closes the connection during a handshake, a “broken pipe” error may result from tls.Conn.Handshake(). This can mask any, more detailed, fatal alerts that the peer may have sent because a read will never happen. Buffering handshake messages means that the peer will not receive, and possibly reject, any of a flow while it's still being written.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
