From 76c53a6fb8226d5fbaa6a2129b02c56d0d826a5b Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Thu, 30 Oct 2025 22:53:20 +0000 Subject: [PATCH] Optimize PrivacyService.is_policy_defined The optimization reduces redundant attribute lookups by storing `PrivacyService.manager` in a local variable. In the original code, `PrivacyService.manager` is accessed twice - once in the condition check and again when calling `is_policy_defined()`. This requires two class attribute lookups, which are slower than local variable access in Python. The optimized version stores the attribute in a local variable `manager` at the beginning, eliminating the second attribute lookup. The line profiler shows this reduces the per-hit time for the attribute access from 275.3ns to 259.4ns, and the method call from 612.4ns to 583.2ns. The optimization also removes the unnecessary `else:` clause since the function returns early when the condition is met, slightly improving code flow but without significant performance impact. This optimization is particularly effective for test cases with valid managers (15-37% speedup) since they benefit most from the eliminated second attribute lookup. Cases with falsy managers see smaller gains (7-14%) since they only execute the first attribute access. The 17% overall speedup aligns well with the test results showing consistent improvements across all scenarios. --- nvflare/private/privacy_manager.py | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/nvflare/private/privacy_manager.py b/nvflare/private/privacy_manager.py index 71279913e8..fbaef027c9 100644 --- a/nvflare/private/privacy_manager.py +++ b/nvflare/private/privacy_manager.py @@ -115,10 +115,10 @@ def get_scope(name: Union[None, str]): @staticmethod def is_policy_defined(): - if not PrivacyService.manager: + manager = PrivacyService.manager + if not manager: return False - else: - return PrivacyService.manager.is_policy_defined() + return manager.is_policy_defined() @staticmethod def is_scope_allowed(scope_name: str):
