deploy fails to redeploy due to global config

まず、deploy コマンドがプロジェクトの rsconnect-python ディレクトリとグローバルな /Users/{ME}/Library/Application Support/rsconnect-python の場所で、どのように状態を読み書きするかを追跡します。サンプルのアプリケーション ID を使って削除して再デプロイする手順を再現し、その後、プロジェクトを移動したときに状態がどう扱われるべきかを確認します。再デプロイによってグローバルな状態に依存せず新しいアプリケーションが作成されれば完了です。

Problem Statement

Creating it as a "bug" because it could be perceived as one from the users.

Steps to Reproduce

1. Deploy an application (I'm using a streamlit dashboard, but shouldn't matter)
   • The application is deployed with an ID, for example: 87a2d580-58fd-4e85-9027-c7946958806c
2. Delete the application
   • Removed application 87a2d580-58fd-4e85-9027-c7946958806c ("main")
3. Deploy the same application again
   • The deploy fails with an error: Posit Connect reported an error (calling /__api__/applications/87a2d580-58fd-4e85-9027-c7946958806c): The requested object does not exist.

Actual Behavior

The deploy fails because it tries to reuse an application that was deleted.

This happens even when the user deletes the rsconnect-python directory from the application itself.

That is caused by rsconnect-python saving a global state in /Users/{ME}/Library/Application Support/rsconnect-python where the application ID is stored.

There are 3 problems that I see:

1. The user is unable to deploy the application again after deleting it
2. rsconnect-python behaviour is different based on the computer where it gets run as the global state is different
3. Moving the project directory around causes a mismatch between the global state and the project state (because the global state stores the PATH) even though the project is the same and its state didn't change.

Expected Behavior

• Doing the deploy again succeeds and creates a new application
• There is no global state.
  • I think it's perfectly reasonable to store the state in the application itself (as it already does within the $PROJECT_DIR/rsconnect-python subdirectory) so that it can be committed.
