• Getting Started

TODO

Before this can be put to real work the mdb usage should be revised.
The revision should try to group all the stores into a single file It should also make the queues all use a single file. Furthermore it should look into zookeeper or raft for providing leader election and log replication.

Developing the app

There is a Makefile included that has a setup task and that will download all the necessary dependencies. Once you've completed the steps below for getting a dev env set up

git clone https://github.com/reverb/exeggutor $GOPATH/src/github.com/reverb/exeggutor
cd $GOPATH/src/github.com/reverb/exeggutor
make setup

running tests, this works in every subdirectory:

make test

Create a distribution:

cd agora
make distclean
make dist

Setting up linux build environment

For this we'll need vagrant, virtualbox and ansible, if you already followed the instructions in the ansible playbooks repo, then you can skip this part.

# you can run this by invoking ./install-tools.sh
brew install --cross-compile-common go
brew tap phinze/cask
brew install brew-cask
brew install ansible 
brew cask install vagrant
brew cask install virtualbox
vagrant plugin install vagrant-vbox-snapshot vagrant-vbguest
vagrant box add casualjim/trusty-vagrant

You should now be able to start the virtual machine, which will also provision it.

vagrant up

If you want ssh access which has sudo access then you can run

vagrant ssh

Setting up a go dev env

Install golang

brew install --cross-compile-common go

Create a folder on your file system. This will be root of your go workspace but not the project.

mkdir -p ~/projects/wordnik/go # or wherever you want to put the go files
export GOPATH=$HOME/projects/wordnik/go
export PATH=$GOPATH/bin:$PATH

Now time to edit .bashrc or .zshrc and perhaps also /etc/launchd.conf if you're on a mac

Add the following to .bashrc or .zshrc

export DOCKER_HOST=tcp://192.168.11.253:4243
export GOPATH=$HOME/projects/wordnik/go # bring godep into scope
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

Open a new shell or reload your shell with

exec $SHELL  # this is preferred over sourcing since it keeps your env clean 

Add this to /etc/launchd.conf if you want vim, sublime, ... to find your go stuff

setenv GOPATH $HOME/projects/wordnik/go
setenv PATH  $HOME/bin:$GOPATH/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin

This will keep it across reboots, now to enable it for your current session

launchctl setenv PATH  $HOME/bin:$GOPATH/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin

If you're using an editor like Sublime, Vim or Emacs you will probably need all or most of the tools below:

• github.com/tools/godep
• code.google.com/p/go.tools/cmd/vet
• code.google.com/p/go.tools/cmd/godoc
• code.google.com/p/go.tools/cmd/goimports
• code.google.com/p/go.tools/cmd/oracle
• code.google.com/p/go.tools/cmd/gotype
• code.google.com/p/go.tools/cmd/cover
• code.google.com/p/rog-go/exp/cmd/godef
• github.com/axw/gocov/gocov
• gopkg.in/matm/v1/gocov-html
• github.com/AlekSi/gocov-xml
• github.com/nsf/gocode
• github.com/golang/lint/golint
• github.com/kisielk/errcheck
• github.com/jstemmer/gotags

Managing dependencies for a project. Currently we can use godep until the community figures out a clear winner.

You can install all these tools with:

make devenv

Editors:

For sublime there is the SublimeGo package

For vim the best one seems to be fatih/vim-go

notes

autosourcing a file

in bash:

cd () {
  builtin cd "$@"
  case $PWD in
    /some/directory) . ./projectSettings.bash;;
  esac
}

in zsh:

# http://stackoverflow.com/questions/17051123/source-a-file-in-zsh-when-entering-a-directory
autoload -U add-zsh-hook
load-local-conf() {
     # check file exists, is regular file and is readable:
     if [[ -f .reverb-env && -r .reverb-env ]]; then
       source .reverb-env
     fi
}
add-zsh-hook chpwd load-local-conf
