Running PHP processing logic after the request is over

This is an experiment on running heavy processing logic after sending the response and finalizing the HTTP request processing. @dmsnell and I tried this as a part of the Site Transfer Protocol explorations.

Our idea was WordPress could process the request and then do some indexing in the remaining execution time. That would happen every n requests or every n seconds or somehow.

// FileReader polyfill for environments that don't support it (like Node.js)
if (typeof FileReader === 'undefined') {
	class FileReader {
		constructor() {
			this.onloadend = null;
		}

		readAsDataURL(blob) {
			// For Node.js environments, we can use Buffer
			if (typeof Buffer !== 'undefined' && blob.arrayBuffer) {

WebSockets in PHP

This is an experiment to run WebSockets in PHP without any extensions meant for WordPress Collaborative Editing.

Both approaches work, but both require custom hosting configuration. The first one – to proxy the traffic to a local WS server. The second one – to enable two-way data flow on the websockets route.

Requiring custom config is not ideal, but it could be a decent synchronization transport on some webhosts.

The preference cascade could go like:

 * Custom Gzip Decompressor.

 * This is slower than all the PHP built-in gzip functions. The only
 * advantage to using this class is that we can pause and resume decompression
 * because we have access to the internal state.
