# abc-bench / task_air_go_rpc__metadata - taskset: [abc-bench](https://harnessreport.com/tasks/abc-bench.md) - difficulty: hard - category: DevTools - language: - runnable from the site: no - agent timeout: 3600s ## Results by harness _none yet_ ## Instruction ``` You are a backend development expert. Please inspect the backend project located in the current directory, determine its programming language and architectural style, and then complete the following code implementation and environment setup tasks. Rebuild the metadata endpoints inside `main.go` so clients can query service facts. GET /info - Keep the handler wired by `registerRouter`. - Respond through `response.ResponseJSON` with `response.ErrnoSuccess` and an `infoPayload`. - Populate `infoPayload.Name` with the static identifier `"air-go rpc demo"`. - Populate `infoPayload.Version` with the result of `serviceVersion()` so the endpoint reflects the `SERVICE_VERSION` environment variable (default `dev`). - Populate `infoPayload.Timestamp` with the current UTC time formatted as `time.RFC3339`. GET /time - Also respond through `response.ResponseJSON` with `response.ErrnoSuccess`. - Return a `timePayload` whose `ServerTime` uses the current UTC timestamp formatted as `time.RFC3339Nano`. Both handlers are read-only and must not mutate global state. They serve as diagnostics for clients verifying build metadata and clock skew, so ensure the timestamps are generated per-request. Please locate the appropriate place in the project and apply the necessary modifications. After completing all source code implementation, create a Dockerfile for this project using the following example template as a reference (Python version): ``` # setup base FROM nikolaik/python-nodejs:python3.12-nodejs22-bullseye RUN apt-get update && apt-get install -y sqlite3 # install dependencies and copy project files WORKDIR /app COPY . /app/ RUN python3 -m pip install -r requirements.txt ENTRYPOINT ["python3", "app.py"] ``` Notes: 1. Ensure that all required project dependencies are properly installed inside the image. 2. The generated Dockerfile must successfully build and run the application. 3. The Dockerfile must be created in the root directory of the backend project, i.e `/app/air-go_rpc/Dockerfile` ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
