From: Tian Yuchen Date: Tue, 14 Jul 2026 03:25:17 +0000 (+0800) Subject: environment: move excludes_file into repo_config_values X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7488b9d1fd505ce1194b98893508fa5b194cf0cd;p=thirdparty%2Fgit.git environment: move excludes_file into repo_config_values The global variable 'excludes_file' is used to track the path to the global ignore file. If this variable is NULL, 'setup_standard_excludes()' in 'dir.c' forcefully evaluates and assigns the XDG default path to it. Continue the libification effort by encapsulating this lazy-loading fallback logic into a proper getter and moving the variable into 'struct repo_config_values'. Since 'excludes_file' is a dynamically allocated string, it requires proper heap memory management. It is safely freed using the newly introduced 'repo_config_values_clear()' function when the repository is torn down.
