net: DialContextTCP()

[gobwas]

Hello! I've search for some similar issues and found this one but looks like it is stale now.

My issue points to inability to dial via tcp with custom context.Context passed.

Current implementation of net.DialTCP() (actually net.dialTCP) is absolutely ready to receive context for dial, but has no exported wrapper that can receive it.

Did you miss https://golang.org/pkg/net/#Dialer.DialContext ?

[gobwas]

@fraenkel no.

conn, err := dialer.DialContext(...)

Does not allow me to setup local address for connection.

[fraenkel]

Sure it can. Set the LocalAddress in the Dialer.

[gobwas]

@fraenkel wow. Thanks! Seems like I really missed this. 👍
By the way, should the net.DialContextTCP() appear?

[fraenkel]

I don't think so. We just need to adequately highlight the proper APIs that people should use. The original ones were modified to leverage the Context based ones but cannot be removed for compatibility reasons.

Closing since there doesn't seem to be anything to do here.
