perf: reduce Console and RichHandler import time by deferring unused imports ## E2E Results | Import | master | This PR | Speedup | |---|---|---|---| | `from rich.console import Console` | 78.1ms | 52.2ms | **1.50x faster** | | `from rich.logging import RichHandler` | 99.4ms | 56.9ms | **1.75x faster** | | `import rich` | 18.2ms | 18.3ms | (already lean) | ## Summary Defer module-level imports that are only needed in specific code paths, move annotation-only imports to `TYPE_CHECKING`, and remove dead code: | File | Change | Savings | |---|---|---| | `logging.py` | Defer `Traceback` to `emit()` (only when `rich_tracebacks=True`) | ~20ms | | `logging.py` | `from __future__ import annotations` + `TYPE_CHECKING` for `Console`, `ConsoleRenderable`, `Highlighter`, `FormatTimeCallable` | ~6ms | | `logging.py` | Replace `pathlib.Path` → `os.path.basename` (also a minor runtime win) | ~4-5ms | | `console.py` | Eliminate `import inspect`; replace `isclass` → `isinstance(x, type)`, `currentframe` → `sys._getframe` | ~10ms | | `console.py` | Defer `pretty` to `Console.print()` | ~3-5ms | | `console.py` | Defer `scope` to `Console.log()` (only when `log_locals=True`) | ~3-5ms | | `console.py` | Defer `getpass` to `Console.input()` (only when `password=True`) | ~2ms | | `console.py` | Defer `html.escape` and `zlib` to export methods | ~2.3ms | | `console.py` | Remove dead `_svg_hash` function (unused since 113997ac, fixes latent NameError) | cleanup | | `segment.py` | Remove dead `logging` import (`getLogger` assigned but never used) | ~2-3ms | | `theme.py` | Defer `configparser` to `Theme.from_file()` | ~1.5ms | | `syntax.py` | Move `Console`, `ConsoleOptions`, `JustifyMethod`, `RenderResult` to `TYPE_CHECKING` | eliminates console.py from syntax import chain | | `protocol.py` | Replace `from inspect import isclass` → `isinstance(x, type)` | prepares for dataclasses removal | | `repr.py` | Defer `import inspect` to `auto_rich_repr()` | prepares for dataclasses removal | All deferred imports are still available at runtime — they're loaded when the code path that needs them is actually hit. The `TYPE_CHECKING` imports are annotation-only and never needed at runtime (files use `from __future__ import annotations`). ## Benchmarks Environment: Standard_D2s_v5 (non-burstable), CPython 3.13.13, hyperfine --min-runs 30 ### Per-module breakdown (this PR) | Module | Time | |---|---| | `import rich` | 18.2ms | | `Console` | 52.5ms | | `RichHandler` | 56.4ms | | `Syntax` | 64.7ms | | `Traceback` | 92.5ms | | `Markdown` | 103.0ms | ## Motivation pip vendors Rich, and `Console`/`RichHandler` are imported on every `pip` invocation. These savings directly improve startup time for pip and every other tool that imports Rich. ## Testing - `pytest tests/` — 952 passed, 25 skipped - `mypy -p rich --no-incremental` — no issues - `black --check` — passes ## Disclosure This PR was developed with AI assistance (codeflash-agent). Benchmarked in a controlled environment (dedicated non-burstable Azure VM). All tests verified across multiple Python implementations.
