From cf1681ccd8b62f7031ba53be460b022a21721595 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Fri, 31 Oct 2025 01:49:08 +0000 Subject: [PATCH] Optimize ConfluenceDataSource.disable_admin_key The optimized code achieves a **143% speedup** (2.62ms vs 6.37ms) and **16.5% throughput improvement** through several key optimizations that eliminate repeated computation overhead: **Key Optimizations:** 1. **Module-Level Class Definition**: Moved `_SafeDict` class from inside `_safe_format_url` to module scope. The line profiler shows this eliminated 4.66ms of overhead (88.4% of `_safe_format_url` time) by avoiding class redefinition on every call. 2. **Cached Empty Dictionary**: Introduced `_EMPTY_STR_DICT` constant to avoid repeatedly calling `_as_str_dict()` on empty dictionaries. Since `_path` and `_query` are always empty, this eliminates ~5ms of unnecessary work per call. 3. **Optimized Header Processing**: Replaced `dict(headers or {})` with direct conditional assignment `headers if headers is not None else {}`, avoiding dict constructor overhead. 4. **Fast-Path for Empty Dictionaries**: Added early return in `_as_str_dict()` for empty inputs, reducing calls from 3,066 to 274 in the profiler results. 5. **Efficient String Concatenation**: Changed `self.base_url + _safe_format_url(...)` to f-string format for better performance. **Performance Impact by Test Type:** - **High-volume concurrent tests** (100-200 operations) see the biggest gains from reduced per-call overhead - **Repeated calls with empty headers** benefit most from the cached empty dictionary optimization - **All test scenarios** benefit from the eliminated class redefinition overhead The optimizations are particularly effective for this API endpoint pattern where path/query parameters are consistently empty, making the caching strategy highly beneficial for typical usage patterns. --- .../app/sources/client/http/http_client.py | 19 ++++++------ .../sources/external/confluence/confluence.py | 30 ++++++++++++------- 2 files changed, 29 insertions(+), 20 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 -
