🔥 鍛冶屋 (Kajiya)

Kajiya is an RBE-compatible REAPI backend implementation used as a testing server during development of Chromium's new build tooling. It is not meant for production use, but can be very useful for local testing of any remote execution related code.

How to use

$ go build && ./kajiya

# Build Bazel using kajiya as the backend.
$ bazel build --remote_executor=grpc://localhost:50051 //src:bazel

# Build Chromium with autoninja + reclient using kajiya as the backend.
$ gn gen out/default --args="use_remoteexec=true"
$ env \
    RBE_automatic_auth=false \
    RBE_service="localhost:50051" \
    RBE_service_no_security=true \
    RBE_service_no_auth=true \
    RBE_compression_threshold=-1 \
    autoninja -C out/default -j $(nproc) chrome

Features

Kajiya can act as an REAPI remote cache and/or remote executor. By default, both services are provided, but you can also run an executor without a cache, or a cache without an executor:

# Remote execution without caching
$ ./kajiya -cache=false

# Remote caching without execution (clients must upload action results)
$ ./kajiya -execution=false
