From f8fe394e7a03edacb06c336b3990d6e488336361 Mon Sep 17 00:00:00 2001 From: ThibG Date: Sun, 11 Jun 2017 22:53:12 +0200 Subject: [PATCH] Fix an error when TagManager.local_url? is called with a bad URI (#3701) TagManager.local_url? was sometimes called with an URI with a nil host, leading to a crash in TagManager.local_url?. This fixes moves the already-existing uri.host.blank? check in front to avoid this case. --- app/services/fetch_link_card_service.rb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/app/services/fetch_link_card_service.rb b/app/services/fetch_link_card_service.rb index ec9b5226e82..c2df7b2f016 100644 --- a/app/services/fetch_link_card_service.rb +++ b/app/services/fetch_link_card_service.rb @@ -36,7 +36,7 @@ class FetchLinkCardService < BaseService def bad_url?(uri) # Avoid local instance URLs and invalid URLs - TagManager.instance.local_url?(uri.to_s) || !%w(http https).include?(uri.scheme) || uri.host.blank? + uri.host.blank? || TagManager.instance.local_url?(uri.to_s) || !%w(http https).include?(uri.scheme) end def skip_link?(a)
