This project is a demo of HTTP2 (with TLS) in Golang.
In order for me to experiment with reproducible builds it also uses gb as the build/vendoring/retrival mechanism instead of go get or godeps. (For one import, http2)

The layout of this repository uses the gb convention of creating a src directory with "my code" and a vendor directory for "other peoples code".
The bin directory is where gb build will output the compiled binaries for each demo.

A gb plugin named "fetch" is used to retrieve the code we need to build.

In this demo, the only thing not in the standard library is http2 itself.

You can create one in each demo directory under src or simply copy-paste the same pair to each directory.

Create a certificate and private key to be used for the http2 demo. No password on the private key with the -nodes option.
openssl req -x509 -newkey rsa:2048 -nodes -keyout localhost.key -out localhost.cert -days 365

NOTE! gb projects do not live in $GOPATH
In fact you do not even need $GOPATH or $GOBIN environment variables set to run gb build!

First time usage:
gb vendor fetch golang.org/x/net/http2
Note that this will create a manifest file in vendor dir if you want to review it.

Additional usage from then on:
gb vendor update --all
You will notice the time stamps of various files in the vendor/src/directory get updated with the current time each time this is ran.

gb build all

This will place each demo in the bin directory.
Run each binary to see what they are doing behind the scenes.

cd bin
# run these one at a time or all at once in different shells if desired
./tls
./notls
./http1.1

Note that http2 without TLS is supported in the specification, but not supported in any widely dispersed user agents, so I have aimed to try to make it work here.

The .gitignore file excludes a couple project dirs that we would probably want checked into source code in a production environment.
Other than, that this project layout would work the same everywhere, even without a $GOPATH.
