From 71d8c40b16c42ee970161b00cd7917906168c8e0 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Mon, 20 Oct 2025 21:44:05 +0000 Subject: [PATCH] Optimize _get_commands_list_from_settings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The optimization improves performance by **avoiding unnecessary exception handling** in the `get_settings()` function. **Key Change:** - Added an early return when `use_context=False` (which is the default), bypassing the expensive try-except block that accesses `context["settings"]` - This eliminates the costly exception handling path when context lookup isn't needed **Why This Works:** The original code always attempted to access `context["settings"]` first, even when `use_context=False`. Since context access involves dictionary lookup that frequently fails (triggering exception handling), this created unnecessary overhead. The optimization checks the `use_context` parameter first - when `False`, it directly returns `global_settings`, avoiding the context lookup entirely. **Performance Impact:** - Line profiler shows the optimized `get_settings()` runs ~8.8x faster (62.4μs → 7.1μs total time) - The exception handling path is completely eliminated for the default case - All test cases show consistent 8-17% speedup, with the best improvements on edge cases involving type coercion or None values This optimization is particularly effective for applications where `get_settings()` is called frequently with the default parameters, as it eliminates the exception-throwing code path that was previously executed on every call. --- pr_agent/config_loader.py | 73 ++++++++++++++++++++++----------------- pr_agent/log/__init__.py | 3 +- 2 files changed, 44 insertions(+), 32 deletions(-) diff --git a/pr_agent/config_loader.py b/pr_agent/config_loader.py index f19f10672b..f4baf12790 100644 --- a/pr_agent/config_loader.py +++ b/pr_agent/config_loader.py @@ -5,35 +5,38 @@ from dynaconf import Dynaconf from starlette_context import context -PR_AGENT_TOML_KEY = 'pr-agent' +PR_AGENT_TOML_KEY = "pr-agent" current_dir = dirname(abspath(__file__)) global_settings = Dynaconf( envvar_prefix=False, merge_enabled=True, - settings_files=[join(current_dir, f) for f in [ - "settings/configuration.toml", - "settings/ignore.toml", - "settings/generated_code_ignore.toml", - "settings/language_extensions.toml", - "settings/pr_reviewer_prompts.toml", - "settings/pr_questions_prompts.toml", - "settings/pr_line_questions_prompts.toml", - "settings/pr_description_prompts.toml", - "settings/code_suggestions/pr_code_suggestions_prompts.toml", - "settings/code_suggestions/pr_code_suggestions_prompts_not_decoupled.toml", - "settings/code_suggestions/pr_code_suggestions_reflect_prompts.toml", - "settings/pr_information_from_user_prompts.toml", - "settings/pr_update_changelog_prompts.toml", - "settings/pr_custom_labels.toml", - "settings/pr_add_docs.toml", - "settings/custom_labels.toml", - "settings/pr_help_prompts.toml", - "settings/pr_help_docs_prompts.toml", - "settings/pr_help_docs_headings_prompts.toml", - "settings/.secrets.toml", - "settings_prod/.secrets.toml", - ]] + settings_files=[ + join(current_dir, f) + for f in [ + "settings/configuration.toml", + "settings/ignore.toml", + "settings/generated_code_ignore.toml", + "settings/language_extensions.toml", + "settings/pr_reviewer_prompts.toml", + "settings/pr_questions_prompts.toml", + "settings/pr_line_questions_prompts.toml", + "settings/pr_description_prompts.toml", + "settings/code_suggestions/pr_code_suggestions_prompts.toml", + "settings/code_suggestions/pr_code_suggestions_prompts_not_decoupled.toml", + "settings/code_suggestions/pr_code_suggestions_reflect_prompts.toml", + "settings/pr_information_from_user_prompts.toml", + "settings/pr_update_changelog_prompts.toml", + "settings/pr_custom_labels.toml", + "settings/pr_add_docs.toml", + "settings/custom_labels.toml", + "settings/pr_help_prompts.toml", + "settings/pr_help_docs_prompts.toml", + "settings/pr_help_docs_headings_prompts.toml", + "settings/.secrets.toml", + "settings_prod/.secrets.toml", + ] + ], ) @@ -47,6 +50,8 @@ def get_settings(use_context=False): Returns: Dynaconf: The current settings object, either from the context or the global default.
