From 59a913431b825ae538396987932f2ae2546cd8f2 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Sun, 9 Nov 2025 16:02:15 +0000 Subject: [PATCH] Optimize JiraDataSource.remove_level The optimized code achieves an **8% runtime improvement** and **3.1% throughput increase** through several targeted optimizations: **1. Smart Dictionary Conversion (`_as_str_dict`):** The biggest performance gain comes from optimizing `_as_str_dict`, which was consuming 100% of its profiled time doing unnecessary conversions. The optimized version adds two fast paths: - **Empty dict check**: Returns `{}` immediately for empty dictionaries (10.9% of function time) - **Type validation shortcut**: For dictionaries where keys are already strings and values are strings/None, it skips expensive `_serialize_value` calls and just handles None conversion (48.6% of function time) Only 0.4% of calls now go through the expensive conversion path versus 100% in the original. **2. URL Template Optimization (`_safe_format_url`):** Added a fast path that checks if the template contains placeholders (`'{'`) before attempting formatting. This saves unnecessary `format_map` and exception handling overhead for static URLs. **3. Reduced Attribute Access:** Stored `self._client` in a local variable `client` to avoid repeated attribute lookups during the function execution. **4. Pre-conversion Strategy:** Moved `_as_str_dict` calls outside the `HTTPRequest` constructor to separate conversion from object creation, improving code clarity and potentially enabling future optimizations. **Performance Impact:** The line profiler shows the total time for `_as_str_dict` dropped from 2.67ms to 2.09ms (22% reduction), which directly contributes to the overall 8% speedup. These optimizations are particularly effective for workloads with: - Many HTTP requests with empty or string-only headers/parameters (common case) - Static URL templates without placeholders - High-frequency API calls where small per-request savings compound significantly The improvements maintain full behavioral compatibility while optimizing the most expensive operations identified in the profiling data. --- .../app/sources/client/http/http_client.py | 36 ++++++---- .../python/app/sources/external/jira/jira.py | 67 ++++++++++++++----- 2 files changed, 72 insertions(+), 31 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..0e57d51b1f 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 -
