From 7bb4089ee4fe2d1483d7ca8b844f594d720555f6 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Sun, 9 Nov 2025 22:16:39 +0000 Subject: [PATCH] Optimize JiraDataSource.create_issue_type_screen_scheme The optimization achieves a **5% runtime improvement** through strategic memory allocation reduction in the HTTP request construction path. Here's what was optimized: **Key Optimizations:** 1. **Module-level constant reuse**: Replaced repeated dict allocations with pre-allocated constants: - `_EMPTY_DICT` for always-empty `_path` and `_query` parameters - `_DEFAULT_HEADERS` for the standard Content-Type header - Only creates new dicts when custom headers are actually provided (4 out of 556 calls in profiling) 2. **Conditional header construction**: The original code always created a new dict with `dict(headers or {})` and called `setdefault()`. The optimized version only allocates when headers are provided, otherwise reuses the constant. 3. **Safer URL formatting**: Changed from `.format(**request.path_params)` to `.format_map(request.path_params)` in HTTPClient for more robust parameter substitution. **Performance Impact:** The line profiler shows the optimization reduced overhead in dictionary operations - particularly beneficial for the common case where no custom headers are provided (552/556 calls). The `_as_str_dict` function time decreased from 1.81ms to 1.72ms, and overall request construction became more efficient. **Test Case Performance:** The optimization is most effective for: - High-volume concurrent requests (throughput tests with 50-200 requests) - Repeated calls with default parameters (no custom headers) - Basic usage scenarios that don't require custom headers While throughput remained constant at 139k ops/sec due to the async nature being I/O bound, the 5% runtime reduction means less CPU overhead per request, which is valuable in high-frequency API scenarios where this Jira integration might be called repeatedly. --- .../app/sources/client/http/http_client.py | 31 ++++++----- .../python/app/sources/external/jira/jira.py | 52 ++++++++++++++----- 2 files changed, 57 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..f84d164f23 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 -
