フォーラムがダウンし、再構築中にdb:migrateエラーが発生しました

こんにちは。私たちのフォーラム (https://forum.pardus.org.tr) がダウンし、コンソールにアクセスして再構築を試みると、次のエラーが発生しました:

Pups::ExecError: cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' failed with return #<Process::Status: pid 606 exit 1>

ログにもう一つエラーがあります:

rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

ERROR:  unsupported Unicode escape sequence
DETAIL:  \u0000 cannot be converted to text.

以下にログを示します。すべてのプラグインを無効化し、システムを更新し、システムを再起動しましたが、どれも効果ありませんでした。
再構築に失敗した後、アプリは起動しませんが、./launcher start app を実行すると起動します。その後、ウェブサイトは空白の画面を表示し、背景にいくつかのカスタム CSS が読み込まれています:

システムは Ubuntu 16.04.7 LTS で、Discourse の Docker バージョンを使用しています。

何かアドバイスはありますか?

Note: checking out 'v1.0.3'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now atd1db030 が新しいバージョンを切り出しました

データベース内の既存のレコードでマイグレーションが停止しているように見えます。以下の手順を試してみましたか?

  • ./launcher enter app
  • rails c
  • Post.where("raw LIKE '%\u0000%'")

これにより、あなたのサイトの投稿にその Unicode エスケープシーケンスが含まれているか確認できます。私はこの方法を実証していないため、結果は環境によって異なる可能性があります。

@justin ありがとうございます。コマンドを実行した後の出力は以下の通りです:

[1] pry(main)> Post.where("raw LIKE '%\u0000%'")
=> #<Post::ActiveRecord_Relation:0x119cc>

1 行のみ表示されています。この出力をどのように解釈すればよいでしょうか?今後の対応についてご提案をお願いします。

フォラムを運用開始しました。ただし、トップに「極度の負荷により、現在はログアウトしたユーザーと同様に全ユーザーに表示されています」というバナーが表示されています。詳細は後ほど投稿します。

残念ながら、問題が再発しました。アップグレード後、./launcher start app でサイトを起動することはできますが、半分しか動作していないようです。ユーザーはユーザー名とパスワードでのログインができず、他のログイン方法でのみログインできます。また、ユーザーのプロフィールカードを表示しようとしても、ポップアップ表示されません。誰かがユーザーのページや自分のプロフィールページを開こうとすると、タイトルが「Oops - Error 500」の以下のエラーメッセージが表示されます。

Oops

このディスカッションフォーラムを動かしているソフトウェアで予期しない問題が発生しました。ご不便をおかけして申し訳ありません。

エラーに関する詳細情報はログに記録され、自動通知が生成されました。確認いたします。

これ以上の対応は必要ありません。ただし、エラー状態が継続する場合は、エラーを再現する手順など、追加の詳細をサイトのフィードバックカテゴリに投稿してください。

今回は Web インターフェースからアップグレードも試みました。他のいくつかのもの(Docker Manager や公式プラグインなど)のアップグレードには成功し、管理者ログでアップグレードの結果を確認することもできました。
しかし、Discourse インスタンスのアップグレードを試みると、依然として失敗し、ログは以下のようになりました:

[DEPRECATED] The `--deployment` flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use `bundle config set --local deployment 'true'`, and stop using this flag
[DEPRECATED] The `--without` flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use `bundle config set --local without 'test development'`, and stop using this flag
Warning: the running version of Bundler (2.2.15) is older than the version that created the lockfile (2.2.19). We suggest you to upgrade to the version that created the lockfile by running `gem install bundler:2.2.19`.
