From 1d63b4ad650144f8face66368a461b6e2d18d527 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Wed, 15 Apr 2020 16:19:31 +0000 Subject: [PATCH] gvfs: allow overriding core.gvfs We found a user who had set "core.gvfs = false" in their global config. This should not have been necessary, but it also should not have caused a problem. However, it did. The reason is that gvfs_load_config_value() is called from config.c when reading config key/value pairs from all the config files. The local config should override the global config, and this is done by config.c reading the global config first then reading the local config. However, our logic only allowed writing the core_gvfs variable once. Put the guards against multiple assignments of core_gvfs into gvfs_config_is_set() instead, because that will fix the problem _and_ keep multiple calls to gvfs_config_is_set() from slowing down.
