performance.py DOX

Purpose

• Own the performance.py helper module.
• This module provides lightweight performance tracing helpers.
• Keep this file-level DOX profile synchronized with performance.py because this directory is intentionally flat.

Ownership

• performance.py owns the runtime implementation.
• performance.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Top-level functions:
• trace_performance(show_all=..., color=..., unicode=...): Decorator that profiles a function and prints a call tree when it finishes.

Runtime Contracts

• Helper modules own reusable framework APIs and must preserve public callers unless all callers, tests, and docs are updated together.
• Update this file whenever public functions, classes, persistence behavior, path/security assumptions, side effects, or cross-module contracts change.
• Imported dependency areas include: functools, inspect, pyinstrument.

Key Concepts

• Important called helpers/classes observed in the source: inspect.iscoroutinefunction, functools.wraps, Profiler, profiler.start, profiler.stop, func, profiler.output_text.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve public helper APIs used by core code and plugins unless every caller is updated.
• Keep path, auth, secret, persistence, network, and subprocess behavior explicit and bounded.
• Prefer adding cohesive helper functions here only when behavior is reused across modules.

Verification

• Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
• Related tests observed by source search:
  • tests/test_extensions_stress.py
  • tests/test_ws_manager.py
