From 5cdf18e7cd6d6e3ce2fb21fef2b5ec84e570abf8 Mon Sep 17 00:00:00 2001 From: Glen Choo Date: Tue, 28 Mar 2023 17:51:52 +0000 Subject: [PATCH] config.c: remove current_parsing_scope Add ".parsing_scope" to "struct config_reader" and replace "current_parsing_scope" with "the_reader.parsing_scope. Adjust the comment slightly to make it clearer that the scope applies to the config source (not the current value), and should only be set when parsing a config source. As such, ".parsing_scope" (only set when parsing config sources) and ".config_kvi" (only set when iterating a config set) should not be set together, so enforce this with a setter function. Unlike previous commits, "populate_remote_urls()" still needs to store and restore the 'scope' value because it could have touched "current_parsing_scope" ("config_with_options()" can set the scope).
