Adds the (*tls.Conn).HandshakeContext method. This allows us to pass the context provided down the call stack to eventually reach the tls.ClientHelloInfo and tls.CertificateRequestInfo structs. These contexts are exposed to the user as read-only via Context() methods. This allows users of (*tls.Config).GetCertificate and (*tls.Config).GetClientCertificate to use the context for request scoped parameters and cancellation. Replace uses of (*tls.Conn).Handshake with (*tls.Conn).HandshakeContext where appropriate, to propagate existing contexts.

The <code>go</code> <code>get</code> <code>-insecure</code> flag is
|
|
deprecated and has been removed. To permit the use of insecure schemes
|
|
when fetching dependencies, please use the <code>GOINSECURE</code>
|
|
environment variable. The <code>-insecure</code> flag also bypassed module
|
|
sum validation, use <code>GOPRIVATE</code> or <code>GONOSUMDB</code> if
|
|
you need that functionality. See <code>go</code> <code>help</code>
|

<code>environment</code> for details.

<a href="/pkg/crypto/tls#Conn.HandshakeContext">(*Conn).HandshakeContext</a> was added to
|
|
allow the user to control cancellation of an in-progress TLS Handshake.
|
|
The context provided is propagated into the
|
|
<a href="/pkg/crypto/tls#ClientHelloInfo">ClientHelloInfo</a>
|
|
and <a href="/pkg/crypto/tls#CertificateRequestInfo">CertificateRequestInfo</a>
|
|
structs and accessible through the new
|
|
<a href="/pkg/crypto/tls#ClientHelloInfo.Context">(*ClientHelloInfo).Context</a>
|
|
and
|
|
<a href="/pkg/crypto/tls#CertificateRequestInfo.Context">
|
|
(*CertificateRequestInfo).Context
|
|
</a> methods respectively. Canceling the context after the handshake has finished
|
|
has no effect.
