Delivery Optimization Client

This repository contains source code for the following DO components:

• Agent
• SDK
• Plug-ins

Agent

Delivery Optimization HTTP downloader with Microsoft Connected Cache support.

SDK

Library for enabling inter-process communication (IPC) through native C++ code for Delivery Optimization Agent on Linux.

Plug-ins

Add-on that enables APT downloads to go through Delivery Optimization Agent. It is requires the SDK and Agent components.

Getting Started

Follow the development machine setup on each desktop you'd like to use.

Development Machine Setup

Clone the repository locally from terminal:

> cd (to working directory of your choosing)
> git clone https://github.com/microsoft/do-client

Run the appropriate bootstrapper depending on development machine platform:

> cd build/bootstrap

Building DO client components

NOTICE:
If you are modifying this project and distributing your own custom build, please modify the DO_BUILDER_IDENTIFIER cmake variable located in https://github.com/microsoft/do-client/blob/main/CMakeLists.txt

After setting up your development machine, navigate back into the project root

> cd <project root>

We provide an easy-to-use python script for building our client components from the project root, you can inspect build.py for additional build flags
On debian-based systems, run this command to build the client and package it as a .deb file

> python3 build/build.py --project agent --package-for deb

Run this command to build the sdk

> python3 build/build.py --project sdk --package-for deb

In order to build the plugin, you must build & install the sdk, an easy way to do this is to install the the packages you produced in the previous two steps

Navigate to the build output directory for the agent and install the agent package

> cd /tmp/build-deliveryoptimization-agent/linux-debug/
> sudo apt-get install ./deliveryoptimization-agent*.deb

The sdk produces a runtime and development package, in this case you'll want to install both
Navigate to build output directory for the sdk and install both packages

> cd /tmp/build-deliveryoptimization-sdk/linux-debug/
> sudo apt-get install ./libdeliveryoptimization*.deb

With the sdk installed, you can now build the plugin by navigating back to the project root

> cd <project root>
> python3 build/build.py --project plugin-apt --package-for deb

At this point, you should have built and packaged all components

Testing DO Client components

As guidance, please ensure proper code coverage for project contributions
Unit tests for the agent and sdk are produced as a part of the above build command, you can find them in the build output directory

> cd /tmp/build-deliveryoptimization-agent/linux-debug/client-lite/test

Our tests utilize the GTest unit testing framework, which supports test filtering via command line
You can run all agent tests by running

> ./deliveryoptimization-agent-tests

You can filter for specific tests as well, reference the GTest documentation for filtering rules and syntax

> sudo ./deliveryoptimization-agent-tests --gtest_filter=DownloadManagerTests*

The test executable for the SDK is located in the sdk build output as well

> cd /tmp/build-deliveryoptimization-sdk/linux-debug/sdk-cpp/tests

The sdk tests expect a running do-agent, you can either manually run the agent executable from its build output or install the agent package as you may have done while building the plugin
You can run the sdk tests just like the agent tests

> sudo ./deliveryoptimization-sdk-tests

And filter them similarly

> sudo ./deliveryoptimization-sdk-tests --gtest_filter=DownloadTests*

Support

This repository is currently in a Public Preview state. During this phase, all DO components found in this repo will be supported for 90 days beyond the release date of a new release. At the end of the 90 day window, we will not guarantee support for the previous version. Please plan to migrate to the new DO components within that 90-day window to avoid any disruptions.

Filing a Bug

Please file a GitHub Issue to ensure all issues are tracked appropriately.
