SSO ログインによる新規ユーザー作成時の Discourse DB エラー

Eingang · 2019 年 9 月 2 日午後 10:14

Summary

Discourse DB constraint error because of duplicate key values generated when users without an account attempt to log in via SSO. Causes internal server error (500) to be seen via external proxy.

Discussion

On August 28th or 29th, I updated Discourse to the latest beta (v2.4.0.beta2) along with all the installed Discourse plug-ins. Around the same time, I also updated SeAT, and reconfigured Discourse to use a UNIX socket, which the external Apache can proxy/reverse proxy to. Prior to that, people were able to login via SeAT’s EvE Online SSO and new Discourse user accounts would be created for them if they didn’t already have one.

Since then, no new user accounts have successfully been created. Instead, the three people who have tried have generated Failed to create or lookup user: ERROR: duplicate key value violates constraint "idx_category_users_user_id_category_id" DETAIL: Key (user_id, category_id)=(36, 6) already exists. errors. The category_id is always 6 but the user_id varies between 33 and 44, even repeating numbers.

Assuming that category_id refers to entries in categories, then 6 seems to be Grass Clippings. Assuming that user_id refers to entries in users, then we don’t have any entries higher than 32.

Grass Clippings as a category is restricted for at least reading to people in the 2GTHRDiscourse, 2GTHRHighCouncil, and GRoLLake groups. At least one of the people trying to connect had an add_groups command that included all three groups. The first person did not yet have one of the three, and the middle person had at least one of the three. They all generate the same kind of database error with the identical details except except the user_id.

People with Discourse accounts created by logging in via SSO prior to the upgrades do not seem to be experiencing problems logging in.

Things Tried or Looked At

Turning off force https and reverting back to external Apache proxying to nginx ports.
Unsurprisingly, this had no effect.
Debugging and fixing common SSO issues
Watch out for double url encoding of SSO payload
Followed through the backtrace and could see Discourse made it to models/discourse_single_sign_on.rb at line 203 of match_email_or_create_user() where it makes a call to User.create!(). Alas, the logging of the params, etc. is after that point, which it never gets to because it stops processing and returns a HTTP error 500. I checked shared/log/rails/production.log.* just in case.

Other Comments

SeAT: While the SeAT Discourse plug-in wasn’t updated, many components of SeAT were. It’s possible something in there has changed. However, the error is clearly on the Discourse side when trying to create or lookup a non-existent user, so I’m somewhat dubious the problem is on the SeAT side.
Discourse: I can’t remember what beta version of Discourse I was running before the upgrade. I’d guess it had probably been at least a month or two since I’d last upgraded.

Additional Details

これはこのコードに関連しています：

github.com/discourse/discourse

app/models/user.rb

b9954b53b


      
          def set_default_categories_preferences
            return if self.staged?
          
            values = []
          
            %w{watching watching_first_post tracking muted}.each do |s|
              category_ids = SiteSetting.get("default_categories_#{s}").split("|").map(&:to_i)
              category_ids.each do |category_id|
                next if category_id == 0
                values << "(#{self.id}, #{category_id}, #{CategoryUser.notification_levels[s.to_sym]})"
              end
            end
          
            if values.present?
              DB.exec("INSERT INTO category_users (user_id, category_id, notification_level) VALUES #{values.join(",")}")
            end
          end

ここで起きたことは、カテゴリユーザーのインデックスを以下のように修正したことです：

github.com/discourse/discourse

app/models/category_user.rb

b9954b53b


      
          #  idx_category_users_category_id_user_id  (category_id,user_id) UNIQUE
          #  idx_category_users_user_id_category_id  (user_id,category_id) UNIQUE

サイト設定で、両方とも「デフォルトで監視」かつ「デフォルトで追跡」されているグループがありますか？

以下を確認してください：default categories watching、default categories tracking、default categories muted、default categories watching first post

これで修正されます：

diff --git a/app/models/user.rb b/app/models/user.rb

ただし、この修正はあまり気に入っていません。サイト設定は保存時に重複がないことを検証し、不良データを移行すべきです。

@daniel あなたがこの新しい制約を導入したのだと思います。サイト設定を設定する際に検証を追加するフォローアップはどうでしょうか？

追跡されているカテゴリとウォッチされているカテゴリはありますが、それらの間には重複はありません。これらはすべてトップレベルのカテゴリです。ただし、「デフォルトでウォッチするカテゴリ」と「デフォルトで最初の投稿をウォッチするカテゴリ」の間には重複があります。あるカテゴリが両方に含まれており、そのカテゴリIDが私のデータベース制約エラーで言及されているカテゴリIDと一致しています。これが問題の一部でしょうか？

自分自身への返信：カテゴリをdefault categories watching first postから削除し、default categories watchingにのみ存在するようにしたところ、問題が解決しました。以前はログインできなかったアカウントを持たないユーザーが、今ではログインできるようになりました。

このバグをちょうど体験しました。

default categories regular で「Recruitment Notes」と「Partner Notes」が重複していたため、ユーザーがサインインできませんでした。

設定を保存する際に重複を防止するのは非常に簡単であるはずです。ただし、履歴の修正については確信が持てません。

@vinothkannans 保存時にこれらのデフォルト設定が適切に処理されるよう確認してください。

重複を削除する
カテゴリ A の「デフォルト視聴」を保存しようとしているが、すでにカテゴリ A に「デフォルト追跡」が設定されている場合は、問題点を説明してエラーを発生させる

この事象が起きた原因として、私の推測は以下の通りです。

「Partner Notes」を独自のカテゴリとして作成し、「Default Categories Regular」に設定しました。
「Recruitment Notes」を独自のカテゴリとして作成し、「Default Categories Regular」に設定しました。
「Organizers」を独自のカテゴリとして作成し、「Default Categories Regular」に設定しました。
「Partner Notes」と「Recruitment Notes」の設定を変更して、親カテゴリを「Organizers」にしました（おそらく、「Default Categories Regular」の設定には変更を加えませんでした）。

このバグの修正を強く支持します。新規ユーザーがサインアップできない状態は壊滅的であり、かつ発見が困難です。新規ユーザーは単に諦めて、誰も助けを求めない可能性が高いためです。

当面の間、エラーメッセージに「サインアップで問題が引き続き発生する場合は、サポートまで site email までご連絡ください」という文言を追加することを提案します。
