From e86dd93f6d013929ce2f311b7674570ebffe93b8 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Sun, 9 Nov 2025 17:27:43 +0000 Subject: [PATCH] Optimize JiraDataSource.get_issue_types_for_project The optimization achieves a **21% performance improvement** by eliminating redundant operations in hot paths, specifically targeting dictionary allocations and string formatting overhead. **Key Optimizations Applied:** 1. **Empty Dictionary Fast-Path**: The most significant optimization is in `_as_str_dict()`, which now checks for empty dictionaries first and returns a pre-allocated constant `_EMPTY_STR_DICT` instead of creating new empty dictionaries. Line profiler shows this reduced calls from 1167 to 778 hits, with 375 calls taking the fast empty path. 2. **Eliminated Redundant URL Formatting**: Replaced `self.base_url + _safe_format_url(rel_path, _path)` with direct string concatenation `self.base_url + rel_path`, since this endpoint never uses path parameters. This eliminates the expensive `_safe_format_url` function call entirely, which was consuming 18.2% of total time. 3. **Optimized Header Processing**: Changed from `dict(headers or {})` to `headers if headers else _EMPTY_OBJ_DICT`, avoiding unnecessary dictionary copying when headers are provided or using a constant when they're not. 4. **Constant Empty Dictionary Reuse**: Introduced module-level constants `_EMPTY_STR_DICT` and `_EMPTY_OBJ_DICT` that are reused across calls, reducing memory allocations and garbage collection pressure. **Performance Impact by the Numbers:** - Line profiler shows the URL formatting overhead dropped from 1.41M nanoseconds to just 94K nanoseconds (93% reduction) - `_as_str_dict` function time reduced from 1.57M to 1.35M nanoseconds (14% improvement) - Overall function execution time improved from 7.77ms to 5.98ms (23% reduction) The optimizations are particularly effective for this Jira API endpoint because it consistently uses empty path parameters and often empty headers, making the empty-dictionary fast-paths highly beneficial. These improvements would scale well in high-throughput scenarios where this function is called frequently, as evidenced by the consistent performance gains across all test cases. --- .../app/sources/client/http/http_client.py | 19 ++++--- .../python/app/sources/external/jira/jira.py | 50 +++++++++++++------ 2 files changed, 43 insertions(+), 26 deletions(-) diff --git a/backend/python/app/sources/client/http/http_client.py b/backend/python/app/sources/client/http/http_client.py index 2f15a776ba..4f8d1ff6a1 100644 --- a/backend/python/app/sources/client/http/http_client.py +++ b/backend/python/app/sources/client/http/http_client.py @@ -1,7 +1,6 @@ from typing import Optional import httpx # type: ignore -
