+title: Fixes issue with AWS V4 signatures not working with some S3 providers
+merge_request: 21788
+author:
+type: fixed

config/initializers/fog_core_patch.rb

+# frozen_string_literal: true
+#
+# fog-core v2 changed the namespace format:
+#
+# Old: Fog::<service>::<provider> (e.g. Fog::Storage::AWS).
+# New: Fog::<provider>::<service> (e.g. Fog::AWS::Storage)
+#
+# To preserve backwards compatibility, fog-core v2.1.0 tries to load the
+# old schema first, but falls back to the older version if that
+# fails. This creates misleading warnings with fog-aws. See
+# https://github.com/fog/fog-aws/issues/504#issuecomment-468067991 for
+# more details.
+#
+# fog-core v2.1.2 reverses the load order
+# (https://github.com/fog/fog-core/pull/229), which works for fog-aws
+# but causes a stream of deprecation warnings for fog-google.
+# fog-google locked the dependency on fog-core v2.1.0 as a result
+# (https://github.com/fog/fog-google/issues/421) until the new namespace
+# is supported.
+#
+# Since we currently have some Fog gems that have not been updated, this
+# monkey patch makes a smarter decision about which namespace to try
+# first. This squelches a significant number of warning messages.
+#
+# Since this patch is mostly cosmetic, it can be removed safely at any
+# time, but it's probably best to wait until the following issues are
+# closed:
+#
+# fog-google: https://github.com/fog/fog-google/issues/421
+# fog-rackspace: https://github.com/fog/fog-rackspace/issues/29
+# fog-aliyun: https://github.com/fog/fog-aliyun/issues/23
