Introduction

This document will describe how to set up an eduVPN development environment for easy development and running it on your development system.

This is NOT meant to be used as installation instructions! See the deploy instructions instead!

We assume you will be using Fedora >= 28 for development work, but other distributions will of course also work, but some minor details, regarding installation of the required software, will be different.

See DEVELOPMENT_PRACTICES for more information about guidelines to follow.

Preparation

Install the required software:

$ sudo dnf -y install git composer phpunit7 openvpn \
    php-date php-filter php-gettext php-hash php-json php-mbstring \
    php-pcre php-pdo php-spl php-sodium php-pecl-radius php-ldap php-curl \
    php-gd google-roboto-fonts

Download the development_setup.sh script from this repository and run it. It will by default create a directory ${HOME}/Project/eduVPN under which everything will be installed. No root is required!

$ curl -L -O https://raw.githubusercontent.com/eduvpn/documentation/master/development_setup.sh
$ sh ./development_setup.sh

Testing

All projects have unit tests included, they can be run from the project folder, e.g.:

$ cd ${HOME}/Projects/eduVPN/vpn-user-portal
$ phpunit7

Using

A "launch" script is included to run the PHP built-in web server to be able to easily test the portals.

$ cd ${HOME}/Projects/eduVPN
$ sh ./launch.sh

Now with your browser you can connect to the user portal on http://localhost:8082/ and to the admin portal on http://localhost:8083/.

VPN Configuration

To generate the firewall and output the data to stdout:

$ cd ${HOME}/Projects/eduVPN/vpn-server-node 
$ php bin/generate-firewall.php

To generate the OpenVPN server configuration files:

$ cd ${HOME}/Projects/eduVPN/vpn-server-node
$ php bin/server-config.php

The configuration will be stored in the openvpn-config folder.

Developing

If you want to make changes to vpn-lib-common, which is a shared library used by all components you can modify it and push the changes. Using composer update you can retrieve the new version of vpn-lib-common in the projects. You may need to change composer.json and change the version requirements to a (temporary) branch, e.g master. Change this:

"eduvpn/common": "^1",

Into this:

"eduvpn/common": "dev-master",

If you work in a fork of eduvpn/common you can update the URL referenced in the composer.json before running composer update.

Translations

Twig together with gettext is used to take care of translations, see the documentation on how to update the translation files.

Making a Release

Setup

We want to use tar.xz archives, and not zip or tar.gz, for this to work we need to add a little snippet to ${HOME}/.gitconfig:

[tar "tar.xz"]
        command = xz -c

Now, with that out of the way, you can put the following POSIX shell script in ${HOME}/.local/bin/make_release. Make sure you make it "executable" with chmod 0755 ${HOME}/.local/bin/make_release:

#!/bin/sh
PROJECT_NAME=$(basename "${PWD}")
PROJECT_VERSION=${1}

if [ -z "${1}" ]
then
    # we take the last "tag" of the Git repository as version
    PROJECT_VERSION=$(git describe --abbrev=0 --tags)
    echo Version: "${PROJECT_VERSION}"
fi

git archive --prefix "${PROJECT_NAME}-${PROJECT_VERSION}/" "${PROJECT_VERSION}" -o "${PROJECT_NAME}-${PROJECT_VERSION}.tar.xz"
gpg2 --armor --detach-sign --yes "${PROJECT_NAME}-${PROJECT_VERSION}.tar.xz"

Creating a Release

To create a (annotated) tag of your tree:

$ git tag 1.1.4 -a -m '1.1.4'
$ git push origin 1.1.4

Now, from your checked out repository you can run make_release and it will create (by default) a signed archive of the last (annotated) tag of the project. If you want to create a release of a specific tag, provide it as the first argument to make_release:

$ make_release
Version: 1.1.4

The following files are created, e.g:

$ ls -l php-yubitwee-*
-rw-rw-r--. 1 fkooman fkooman 8240 Jun  8 17:18 php-yubitwee-1.1.4.tar.xz
-rw-rw-r--. 1 fkooman fkooman  833 Jun  8 17:18 php-yubitwee-1.1.4.tar.xz.asc

You can verify the signature:

$ gpg2 --verify php-yubitwee-1.1.4.tar.xz.asc
gpg: assuming signed data in 'php-yubitwee-1.1.4.tar.xz'
gpg: Signature made Fri 08 Jun 2018 05:18:37 PM CEST
gpg:                using RSA key 6237BAF1418A907DAA98EAA79C5EDD645A571EB2
gpg: Good signature from "François Kooman <fkooman@tuxed.net>" [ultimate]
