From 008d78d1404ad45bcd3b22b7076f084ed7bb37ed Mon Sep 17 00:00:00 2001 From: Tian Yuchen Date: Sat, 20 Jun 2026 00:21:05 +0800 Subject: [PATCH] environment: move trust_executable_bit into repo_config_values Move the global 'trust_executable_bit' configuration into the repository-specific 'repo_config_values' struct. To ensure code readability, the getter function 'repo_trust_executable_bit()' has been introduced. For now, associated functions access this configuration by explicitly falling back to 'the_repository'.
