Infrastructure of Intel® Media SDK

Repository has all things needed for deploying public infrastructure of Intel® Media SDK.

Repository contains:

• Buildbot configuration
• Build scripts
• Small set of smoke tests (called "ted")
• Test adapter (called "ted_adapter")

How to deploy

Deploy master Buildbot

Dependencies:

• CentOS v7.3
• Python v3.6.x
• postgresql
• git

sudo pip3 install buildbot==1.8.0 buildbot-console-view==1.8.0 buildbot-www==1.8.0

Hint:
It can work with default DB (sqlite) for that it needs to change next value in bb/master/config.py:

DATABASE_URL = "sqlite:///state.sqlite"

Deploy:

git clone https://github.com/Intel-Media-SDK/infrastructure.git
cd ./infrastructure/bb/

buildbot upgrade-master master

#Configure Github`s webhook in your repository in settings-webhooks and create Github`s token after that do:
cd ../common
cp ./msdk_secrets.py.example ./msdk_secrets.py
nano msdk_secrets.py #add your real values

#Start Master Buildbot
buildbot start bb/master

Deploy build box Worker Buildbot

Prerequisites:

• CentOS v6.9 / v7.3
• Python v3.6.x

To set up environment for MediaSDK and install all dependencies do:

• Build Media SDK on CentOS
• Build Media SDK on Ubuntu

Install packages for Buildbot:

sudo pip3 install buildbot-worker==1.8.0
sudo pip3 install gitpython==2.1.5 tenacity==4.5.0 txrequests txgithub service_identity

If you want the environment with X11, install:

sudo yum install libX11 libXext libXfixes libGL libGL-devel libX11-devel 

Read more about the packages here.

Deploy:

git clone https://github.com/Intel-Media-SDK/infrastructure.git

buildbot-worker create-worker --umask=0o2 "worker" "<buildbot_master_IP>:9000" "<your_worker_name>" "pass"

cp infrastructure/common worker/common -R

#Start Worker Buildbot
buildbot-worker start worker

Deploy test box Worker Buildbot

Dependencies:

• CentOS v7.3
• python v3.6.x
• git
• Change permissions on: cd /opt/intel/ && chown <user_who_will_start_the_infrastructure_scripts>:<user_who_will_start_the_infrastructure_scripts> . This change needs for auto-copy of build artifacts to the mediasdk folder (mediasdk folder will be deleted and created again).

# Install git lfs:
# For CentOS do:
sudo yum install curl epel-release
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.rpm.sh | sudo bash
sudo yum install git-lfs
git lfs install

# For Ubuntu do:
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
sudo apt-get install git-lfs

#After that do the same things as described in section "build box Worker"

Deploy:

git clone https://github.com/Intel-Media-SDK/infrastructure.git

buildbot-worker create-worker --umask=0o2 "worker" "<buildbot_master_IP>:9000" "<your_worker_name>" "pass"

cp infrastructure/common worker/common -R

#Start Worker Buildbot
buildbot-worker start worker

Hint:
To use graphical driver (from Media Server Studio) with tests as not root user do:

usermod -a -G video <mediasdk_user>
#And restart session!

Set up shares

ln -s /nfs/import_dir/ci/tests/ /media/tests
ln -s /nfs/import_dir/ci/builds/ /media/builds

Hints

• You can update all configurations by simple executing git pull command!
• Do not forget to add the line with umask = 0o2 to the buildbot.tac file on all your masters and workers for the correct file permissions!
• To have additional information about your worker in Buildbot`s worker list add ip-address to the worker/info/host file.
• Our configuration of Buildbot uses GitPoller so in case of private repos you need to execute git config --global credential.helper store and login once with your infrastructure credentials (otherwise polling will NOT work).

How to reproduce build manually

Our infrastructure was built on the principle of total reproducibility. You can reproduce certain build step from our Buildbot CI on your local machine. For that you have to:

• Install all necessary packages on your OS (see packages above if you want to reproduce open source linux build)
• Clone repositories:

git clone https://github.com/Intel-Media-SDK/infrastructure.git
git clone https://github.com/Intel-Media-SDK/product-configs.git
cd infrastructure/build_scripts

• You can copy the build string from Buildbot (example) or write with your own and execute it. Note to change parameters:
  • build-config - how to build product (you can specify your own config)
  • root-dir - where should be stored binaries after the build and logs
  • manifest - path to manifest.yml file where specified revisions of media components (example)
  • stage - specifies which stage will be executed now (available stages clean, extract, build, install, test, pack, copy) Example:

python3 build_runner.py --build-config /localdisk/bb/worker/build-mediasdk/product-configs/conf_linux_public.py --root-dir /localdisk/bb/worker/build-mediasdk/build_dir --manifest /media/builds/manifest/master/commit/0f3fec8c459eab9d16cbe99a1a76cc236be2226d/manifest.yml --component mediasdk --build-type release --product-type public_linux compiler=gcc compiler_version=6.3.1 compiler=gcc compiler_version=6.3.1 --stage clean

How Buildbot knows about new commits (mechanism of Polling)

Our Buildbot configuration uses GitPoller and GitHubPullrequestPoller to know about new commits.

• GitPoller - uses simple git. During first run Buildbot creates special directory in the root directory of Buildbot with cache of git. With help of this cache it calculates the delta (from which commit should be started CI builds).
• GitHubPullrequestPoller - uses Github API. In this case Github "makes a decision" which commits should be built
