Overview

Records evaluation results and computes trends.

Constant Summary collapse

WRITE_MUTEX =

Serializes the load -> append -> write of the shared trend history file. Batch runs (BatchRunnerService) execute evals concurrently and the trend file is process-global shared state; without this lock, concurrent records race on the temp-file rename and silently lose appended entries.

Constructor Details

#initialize(result, eval_name, skill_names) ⇒ TrendRecorderService

Returns a new instance of TrendRecorderService.

Parameters:

  • result (Hash) —

    The evaluation result from Evaluation::Runner

  • eval_name (String) —

    Name of the eval

  • skill_names (Array<String>) —

    Names of the skills

Class Method Details

.call(result, eval_name, skill_names) ⇒ Hash

Records evaluation results and computes trends.

Parameters:

  • result (Hash) —

    The evaluation result from Evaluation::Runner

  • eval_name (String) —

    Name of the eval

  • skill_names (Array<String>) —

    Names of the skills

Returns:

  • (Hash) —

    Result with success status and trend data

  new(result, eval_name, skill_names).call
end

Instance Method Details

#call ⇒ Hash

Records evaluation results and computes trends.

Loads the trend history once and reuses it for both the trend computation and the append+write, avoiding a duplicate parse per run.

Returns:

  • (Hash) —

    Result with success status and trend data
