It will compile the same, so it's just a matter of code readability or taste which style is better here. I think we should leave it alone, it's fine as it is. - Heikki I agree with Heikki from the code execution point of view. In code execution point of view they are same, however, the code is for user, i think the readability is also important. "canonicalize_path(abs_path);" statement is also condition independent and can be pulled out of both if and else blocks. Removing unnecessary statements makes the code more readable, but it is a matter of choice/style. +1 diff --git a/src/backend/utils/misc/guc-file.l b/src/backend/utils/misc/guc-file.l index c98e220295..b3549665ef 100644 --- a/src/backend/utils/misc/guc-file.l +++ b/src/backend/utils/misc/guc-file.l @@ -522,23 +522,21 @@ AbsoluteConfigLocation(const char *location, const char *calling_file) if (is_absolute_path(location)) return pstrdup(location); + + if (calling_file != NULL) + { + strlcpy(abs_path, calling_file, sizeof(abs_path)); + get_parent_directory(abs_path); + join_path_components(abs_path, abs_path, location); + } else { - if (calling_file != NULL) - { - strlcpy(abs_path, calling_file, sizeof(abs_path)); - get_parent_directory(abs_path); - join_path_components(abs_path, abs_path, location); - canonicalize_path(abs_path); - } - else - { - AssertState(DataDir); - join_path_components(abs_path, DataDir, location); - canonicalize_path(abs_path); - } - return pstrdup(abs_path); + AssertState(DataDir); + join_path_components(abs_path, DataDir, location); } + + canonicalize_path(abs_path); + return pstrdup(abs_path); } -- Best regards Japin Li
