Design: FirmwareBartender

Buildflow

The FirmwareBartender

• Evaluates which firmwares have to be compiled

• Orders the firmware for priority

• If required: Calls git clone/checkout

• If required: Calls git clean

• Builds one firmware after the other * Informs TestBartender about the firmwares which have become ready

Multiprocessing

The firmware shall be built while tests are running.

Therefore, the FirmwareBartender delegates the build to a subprocesses.
