Skylab inventory

Updating inventory schema

Inventory schema is stored as protobuf definitions in the proto/ directory. When you update these protobuf definitions, you must also update the generated python libraries for them.

You need the protoc compiler for this. On gLinux:

sudo apt-get install protobuf-compiler
go get github.com/golang/protobuf/protoc-gen-go

Then, regenerate the libraries inside the chroot:

cros_sdk
(cr) cd ~/trunk/infra/skylab_inventory/protos
(cr) protoc --python_out=../venv/skylab_inventory/protos/ *.proto
(cr) protoc --go_out=../go/src/chromiumos/infra/skylab/inventory/protos/ *.proto
