From 40e5d2303ba1edc51beae66cc15263675980106a Mon Sep 17 00:00:00 2001 From: Akihiko Odaki Date: Mon, 26 Mar 2018 21:02:10 +0900 Subject: Validate HTTP response length while receiving (#6891) to_s method of HTTP::Response keeps blocking while it receives the whole content, no matter how it is big. This means it may waste time to receive unacceptably large files. It may also consume memory and disk in the process. This solves the inefficency by checking response length while receiving. --- app/models/concerns/account_avatar.rb | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'app/models/concerns/account_avatar.rb') diff --git a/app/models/concerns/account_avatar.rb b/app/models/concerns/account_avatar.rb index 9e34a9461..2d5ebfca3 100644 --- a/app/models/concerns/account_avatar.rb +++ b/app/models/concerns/account_avatar.rb @@ -4,6 +4,7 @@ module AccountAvatar extend ActiveSupport::Concern IMAGE_MIME_TYPES = ['image/jpeg', 'image/png', 'image/gif'].freeze + LIMIT = 2.megabytes class_methods do def avatar_styles(file) @@ -19,7 +20,8 @@ module AccountAvatar # Avatar upload has_attached_file :avatar, styles: ->(f) { avatar_styles(f) }, convert_options: { all: '-strip' }, processors: [:lazy_thumbnail] validates_attachment_content_type :avatar, content_type: IMAGE_MIME_TYPES - validates_attachment_size :avatar, less_than: 2.megabytes + validates_attachment_size :avatar, less_than: LIMIT + remotable_attachment :avatar, LIMIT end def avatar_original_url -- cgit
