Source tree layout¶

The Keep server source code is in /services/keep/src/keep.

cd
git clone https://github.com/curoverse/arvados.git
ls arvados/services/keep/src/keep

Install build-prerequisites¶

Install Go. See http://golang.org/doc/install or try this short cut:

wget https://go.googlecode.com/files/go1.2.1.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.2.1.linux-amd64.tar.gz
cd /usr/local/bin
sudo ln -s ../go/bin/* .

(Check https://code.google.com/p/go/downloads/list for other platforms and newer versions.)

Install mux.

GOPATH=~/go go get github.com/gorilla/mux

Run test suite¶

cd ~/arvados/services/keep/src/keep
GOPATH=~/go go test

You should see something like this:
