storage-benchwrapper

storage-benchwrapper is a gRPC wrapper around the storage library for benchmarking purposes.

Running

mvn clean install -DskipTests=true (one time)
cd google-cloud-testing/storage-benchwrapper
export STORAGE_EMULATOR_HOST=localhost:8080
mvn clean install exec:java -DskipTests=true -Dport=8081

Generating .proto sources

Sources are generated as part of the protobuf-maven-plugin plugin, but if you'd like to generate them yourself to see the output you can run:

cd google-cloud-testing/storage-benchwrapper
protoc \
    --plugin=protoc-gen-grpc-java=build/exe/java_plugin/protoc-gen-grpc-java \
    --java_out=src/main/java \
    --grpc-java_out=src/main/java \
    --proto_path=src/main/proto \
    src/main/proto/*.proto

Note that you'll need to delete these, or uncomment the plugin, since multiple definitions of the same class are not allowed.

Note that these should not be committed into git.

Note that you can also mvn compile -DskipTests=true and see sources in target/generated-sources/.

Debugging HTTP requests

To debug HTTP requests, create google-cloud-testing/storage-benchwrapper/logging.properties with the following contents:

# Properties file which configures the operation of the JDK logging facility.
# The system will look for this config file to be specified as a system property:
# -Djava.util.logging.config.file=${project_loc:googleplus-simple-cmdline-sample}/logging.properties

# Set up the console handler (uncomment "level" to show more fine-grained messages)
handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level = CONFIG

# Set up logging of HTTP requests and responses (uncomment "level" to show)
com.google.api.client.http.level = CONFIG

Then, when running the application, add the following flag: -Djava.util.logging.config.file=logging.properties.
