Prometheus: Add README for prometheus-test #4
Conversation
WalkthroughA comprehensive Prometheus Test Framework is introduced, including Python modules for test orchestration, worker management, cryptographic utilities, and data handling. Documentation and configuration files support installation and usage. Additionally, a security audit report for the worker management module is added, detailing identified risks and recommendations.

1-7: Add metadata and context at the top
Consider adding audit date, author, and version metadata (e.g., as a YAML frontmatter or in the Overview) to help track report revisions.
71-100: Enhance server-start polling with backoff and health checks
Good recommendation to replace the fixed sleep. Optionally, you can add exponential backoff to reduce load:delay = 0.5 while time.time() - start_time < timeout: ... time.sleep(delay) delay = min(delay * 2, 2.0)This reduces unnecessary polling under slow conditions.
103-139: Useterminate()and handleTimeoutExpiredexplicitly
Your improvedstopmethod is solid. Add a reference to importloggingat the top and catchsubprocess.TimeoutExpiredto log a clear message:- self.process.terminate() + self.process.terminate() try: - self.process.wait(timeout=5) + self.process.wait(timeout=5) except subprocess.TimeoutExpired as exc: + logging.warning(f"Graceful shutdown timed out: {exc}") self.process.kill()
141-148: Prioritize and quantify recommendations
Consider assigning severity levels (e.g., High/Medium/Low) or a risk score to each recommendation so readers can quickly focus on the most critical actions.

🛠️ Refactor suggestion
Sanitize environment variable values before injection
The sanitize_env_var helper is useful; demonstrate its application in the Worker init:
- self.env[key] = os.getenv(env_var_name)
+ raw = os.getenv(env_var_name)
+ self.env[key] = sanitize_env_var(raw) if raw is not None else NoneAlso remember to import re at the top of the audit when showing this snippet.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

| ### [1] Potential Process Injection Risk | ||
| _File: prometheus_test/workers.py_ | ||
|
|
||
| ```python | ||
| self.process = subprocess.Popen( | ||

| env=self.env, | ||

|
|

| raise ValueError("Entrypoint must be a Path object") | ||

🛠️ Refactor suggestion
Harden server_entrypoint validation
The suggested validate_entrypoint is a good start, but consider also resolving and verifying that the entrypoint resides within the intended base directory to prevent path traversal. For example:
def validate_entrypoint(entrypoint):
- if not isinstance(entrypoint, Path):
- raise ValueError("Entrypoint must be a Path object")
+ if not isinstance(entrypoint, Path):
+ raise ValueError("Entrypoint must be a Path object")
if not entrypoint.is_file():
raise FileNotFoundError(f"Entrypoint {entrypoint} does not exist")
+ # Ensure resolved path is inside project base_dir
+ resolved = entrypoint.resolve()
+ if BASE_DIR.resolve() not in resolved.parents:
+ raise ValueError(f"Entrypoint {entrypoint} is outside of the base directory")Committable suggestion skipped: line range outside the PR's diff.
