From 6b506d5e04a30f6c97321a8bf751cb10c6daeb97 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Mon, 20 Oct 2025 17:39:27 +0000 Subject: [PATCH] Optimize get_user_labels MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The optimization achieves a **21% speedup** through three key improvements: **1. Eliminated Redundant Settings Calls** The original code called `get_settings()` twice - once for `enable_custom_labels` and once for `custom_labels`. The optimization caches the settings object in a single variable, reducing expensive context lookups from 67 calls to 34 calls (50% reduction). **2. O(1) Set Lookups vs O(n) List Lookups** - Added a constant `_SYSTEM_LABELS` set for reserved label checking, replacing the inline list `['bug fix', 'tests', ...]` - Converts `custom_labels` to a set for O(1) membership testing instead of O(n) list scanning - For the large mixed test case with 1000 labels, this optimization alone provides a **206% speedup** (456μs → 149μs) **3. List Comprehension Instead of Manual Loop** Replaced the explicit for-loop with a list comprehension that combines both filtering conditions in a single expression. This reduces Python bytecode overhead and leverages optimized internal iteration. The optimizations are particularly effective for: - **Large label lists**: 11-15% faster for 1000+ labels - **Mixed label scenarios**: Up to 206% faster when filtering both system and custom labels - **High custom label counts**: 11.5% improvement with 500 custom labels The changes maintain identical behavior while significantly improving performance through algorithmic efficiency (O(1) lookups) and reduced function call overhead. --- pr_agent/algo/utils.py | 19 +++++------ pr_agent/config_loader.py | 71 ++++++++++++++++++++++----------------- pr_agent/log/__init__.py | 3 +- 3 files changed, 51 insertions(+), 42 deletions(-) diff --git a/pr_agent/algo/utils.py b/pr_agent/algo/utils.py index 72a0624c51..e14c79550d 100644 --- a/pr_agent/algo/utils.py +++ b/pr_agent/algo/utils.py @@ -30,6 +30,8 @@ from pr_agent.config_loader import get_settings, global_settings from pr_agent.log import get_logger +_SYSTEM_LABELS = {'bug fix', 'tests', 'enhancement', 'documentation', 'other'} + def get_model(model_type: str = "model_weak") -> str: if model_type == "model_weak" and get_settings().get("config.model_weak"): @@ -965,18 +967,15 @@ def get_user_labels(current_labels: List[str] = None): Only keep labels that has been added by the user """ try: -
