http2: initial support for originSet by jasnell · Pull Request #17935 · nodejs/node

jasnell · 2018-01-01T19:27:58Z

In preparation for client side connection Pool and ORIGIN frame support, introduce new properties on Http2Session to identify if the session is secure, provide the alpnProtocol identifier, and generate the initial originSet .

Includes a fix to tls_wrap where the SNI servername was not being set on the client side.

This property's name implies a Set instance yet this returns an Array.

The origin set terminology is adopted from the ORIGIN frame spec. It is a bit confusing. Do you have a suggested alternative?

The name is great; I'm just wondering if it could return the Set (or clone thereof).

"Origin Set" is the name within the spec, I don't think that should determine whether we use Array or Set as the data structure. I don't know if we have any APIs that currently return a Set, I would keep as is.

Returning a Set may imply that it's mutable by the user, which is not the case. Yes, an Array is still mutable, but the property returns a new Array instance on every call. I'd prefer to keep the name and the array return.

doc/api/http2.md

why 'h2c'?

h2c === HTTP/2 over plain text. I'm using it generically because, typically, when using a plain text connection, there's no alpnProtocol property we can use to source it. So if the socket is not a TLSSocket, we assume it's plain text.

Can we avoid parsing a URL for every connected socket?

To my knowlege sockets can be also connected via Unix Domain sockets/windows pipes. There is no remotePort in that case.

Good point. In those cases, there won't be a proper initial origin. I'll update to account for that.

@mcollina ... the ORIGIN spec is pretty clear that the origin must be a validly serialized ASCII-origin, which means our servername must be a pct-encoded ASCII host. The spec also requires that the SNI servername is used to construct the origin. I can see if we can make this more efficient, but I don't think we can completely avoid this.

We could potentially defer the parse such that it occurs the first time the originSet property getter is accessed.

I like that idea. 👍

I'm guessing we do not need to generate a new string and then parse it to generate a new pct-encoded ASCII host.

+1 with this approach.

Unfortunately, as far as I know, the servername isn't guaranteed to be ASCII or percent encoded so we need to at least pass that through.

can that be cached and filled in from the server?

Can you please add a TODO here that the Set will be used by the ORIGIN frame support?

LGTM, just minor nits.

Can we just check this[kEncrypted] here? It's slightly more efficient.

apapirovski · 2018-01-02T15:43:02Z

lib/internal/http2/core.js

Should we define these on the initial class (as undefined) to avoid thrashing of the hidden class? (Maybe originSet too, on kState.)

jasnell · 2018-01-02T18:24:53Z

Updated. originSet is now initialized on the first call to the originSet getter. The initial origin is only added if socket.servername is not == null. remotePort is only added if socket.remotePort is not == null. We still need to do the URL parse, but it's not automatic on every connection. PTAL

Add new properties to `Http2Session` to identify alpnProtocol, and indicator about whether the session is TLS or not, and initial support for origin set (preparinng for `ORIGIN` frame support and the client-side `Pool` implementation. The `originSet` is the set of origins for which an `Http2Session` may be considered authoritative.
