Когато записвате файл в RackSpace CloudFiles с помощта на Paperclip/Fog, възниква таймаут при свързване към нечетен IP адрес

Имам приложение, което съхранява изображения в RackSpace CloudFiles с помощта на Paperclip. Работи добре, но напоследък не записва файлове. Грешката, която възниква е:

Excon::Errors::SocketError (Connection timed out - connect(2) for 94.236.107.224:443 (Errno::ETIMEDOUT)):

В excon/socket.rb добавих някои отстраняване на грешки, за да видя съдържанието на @data в момента, в който е направена заявката. Това е:

{
  :chunk_size        => 1048576, 
  :ciphers           => "HIGH:!SSLv2:!aNULL:!eNULL:!3DES",

  :debug_response    => true, 
  :headers           => {"User-Agent" => "fog/1.22.0"}, 
  :idempotent        => false, 
  :instrumentor_name => "excon", 
  :middlewares       => [Excon::Middleware::ResponseParser, Excon::Middleware::Expects, Excon::Middleware::Idempotent, Excon::Middleware::Instrumentor, Excon::Middleware::Mock],

  :nonblock          => true,
  :omit_default_port => false,
  :persistent        => false,
  :read_timeout      => 60,

  :ssl_verify_peer   => true,

  :host              => "lon.auth.api.rackspacecloud.com",
  :path              => "/v2.0",
  :port              => 443,
  :query             => nil,
  :scheme            => "https",
  :user              => nil,
  :password          => nil
}

Хостът е lon.auth.api.rackspacecloud.com, което се преобразува в 92.52.64.197 (на сървъра, както и локално).

Грешката обаче е, защото връзката към 94.236.107.224 изтече. Обратното търсене на този IP показва, че той също е свързан с името на хоста за удостоверяване:

$ host 94.236.107.224
224.107.236.94.in-addr.arpa domain name pointer lon.auth.api.rackspacecloud.com.

Предполагам, че този IP вече не се използва за услугата за удостоверяване, но не мога да разбера защо изобщо е свързан с него.

Така че трябва да знам:

  1. Защо се свързва лошият IP, след като не се показва в дневника?
  2. Как да поправя това, така че да се използва правилният сървър?

Ето пълната грешка, която възниква:

Успях успешно да се удостоверя срещу lon.auth.api.rackspacecloud.com. Предполагам, че може да има нещо нередно с DNS конфигурацията. Нека намеря някой, който да проучи този проблем вместо вас.

Благодаря Кайл. Някой от екипа за поддръжка на RS предложи да превключа към lon.identity.api.rackspacecloud.com, което изглежда помага, но след това получавам грешката: Unknown region :dfw for service cloudFiles. Please use one of the following regions: :lon - изглежда обещаващо, но не съм сигурен къде да го задам (или откъде идва :dfw. - person Colin; 23.04.2014

@Colin Това е регионът - можете да го зададете, като предоставите rackspace_region: :lon, където предавате останалите си идентификационни данни (потребителско име, API ключ) на Paperclip. :-) - person Ash Wilson; 23.04.2014

Благодарим на @geemus, @Kyle-Rames и @AshWilson за улики към пъзела.

Поддръжката на RS ми каза да променя сървъра за удостоверяване на lon.identity.api.rackspacecloud.com, което направих, но след това видях грешката:

Unknown region :dfw for service cloudFiles. Please use one of the following regions: :lon

Задаването на региона с rackspace_region: :lon в paperclip_defaults.rb сортира това и нещата работят отново.

Не съм сигурен относно спецификата от страна на Rackspace на нещата, които биха довели до това. В рамките на excon разрешаването на ip се случва в рамките на Excon::Socket#connect. Не съм сигурен колко знаете за дребните неща на тези неща, но реших, че ще ви насоча поне в тази посока, в случай че може да помогне: https://github.com/geemus/excon/blob/master/lib/excon/socket.rb#L167

Това просто остава на ниво сокет поне в момента (просто преглеждаме това веднъж при свързване на сокет и не го разпространяваме към хеша на данните). Все пак не трябва да отменяте това (поне според моя опит поведението по подразбиране е правилното). Вероятно просто бих препоръчал да подадете проблема в github срещу fog на този етап (https://github.com/fog/fog/issues/new), за да мога да насоча към него хората от Rackspace.
