PHP HTTP/2 Server Push Example

What/Why

This is a sample script/docker container build to test a patch that adds support for curls new HTTP/2 server push support.

Setup

Docker

Build and run the docker container:

$ docker build -t $USER/php-http2-push-example .
$ docker run $USER/php-http2-push-example

To debug it yourself:

Start the docker container:

$ docker run -ti $USER/php-http2-push-example /bin/bash

Run nghttpd inside the container from a different terminal:

$ docker run -ti $USER/php-http2-push-example nghttpd --htdocs=./curl-http2-dev --verbose --echo-upload --push=/index.html=/LICENSE --push=/index.html=/README.md 8443 ./curl-http2-dev/privkey.pem ./curl-http2-dev/server.pem

Run gdb:

$ gdb --args php-src/sapi/cli/php ./php-http2-push-example/push.php https://localhost:8443/index.html 
gdb> run

Expected Behavior:

It should spit out three documents, and show a bunch of nghttpd output either intermingle, or if you're debugging it yourself, then the nghttpd output will be in the second terminal.

It should also show a var_dump() of the arguments passed to the closure.

Actual Behavior

This currently works as expected except for some memory leaks

Other Tests

Try it without setting the version to HTTP/2, and against another HTTP/2 enabled site, e.g. https://http2.akamai.net
