Summary by Sourcery

This pull request introduces the ability to resume the transfer flow after a consent redirect. It leverages sessionStorage to persist the state of the transfer dialog and endpoint browser, allowing users to continue their transfer process seamlessly after granting consent. It also adds a check for resumeTransferFlow to web/static/main.js to handle the resumption of the transfer flow.

New Features:

• Implements a mechanism to resume the transfer flow after a consent redirect, preserving the state of the transfer dialog and endpoint browser using sessionStorage.

Enhancements:

• The transfer UI manager, endpoint manager, and endpoint browser components now independently manage their state using sessionStorage, allowing the application to restore the UI to its previous state after a redirect or page reload.
• The endpoint browser now caches its state when consent is required, allowing the application to restore the browser to its previous state after the user grants consent.

Reviewer's Guide by Sourcery

This pull request introduces session storage to persist and resume the transfer flow, especially when consent is required. It also refactors the endpoint manager to use a state object and modifies the browse button functionality to support resuming the flow.

Implements session storage to persist and resume the transfer flow across page reloads or when consent is required.	Utilizes sessionStorage to store the state of various components within the transfer dialog. Components independently manage their own sessionStorage to save and load state. Adds a resumeTransferFlow function to web/static/main.js to check for a flag in sessionStorage and resume the flow if it exists. Adds saveCache to TransferUIManager to save the component state to sessionStorage. Adds loadCache to TransferUIManager to load the component state from sessionStorage. Adds saveCache to TransferEndpointManager to save the component state to sessionStorage. Adds loadCache to TransferEndpointManager to load the component state from sessionStorage. Adds saveCache to TransferDialogController to save the component state to sessionStorage.	web/static/components/transfer/transfer-ui-manager.js web/static/components/transfer/transfer-endpoint-manager.js web/static/main.js web/static/components/transfer/transfer-dialog-controller.js web/static/components/endpoint-browse/index.js
Updates the endpoint manager to use a state object for managing its properties.	Replaces individual properties like currentEndpoint, endpointManagerList, currentSearchToken, searchTokenIterator, and initialized with a single state object. Updates references to these properties throughout the TransferEndpointManager class to use the state object.	web/static/components/transfer/transfer-endpoint-manager.js
Modifies the browse button functionality to support resuming the transfer flow after consent is granted.	Caches necessary data for view reconstruction when the browse dialog is opened. Saves the state of the endpointManager and the controller to sessionStorage before showing the browse dialog. Introduces a showBrowseDialog method to encapsulate the browse dialog logic.	web/static/components/transfer/transfer-ui-manager.js

PR Overview

This PR adds a resume flow for the transfer process after consent redirects by leveraging redux‐persist with sessionStorage. Key changes include:

• Configuring a Redux store with redux‐persist for transfer state management.
• Integrating a resume flow in main.js that restores a previous transfer session.
• Updating multiple transfer components (dialog controller, UI manager, endpoint manager, and endpoint browser) to support independent state management and caching.

• The use of new Function to reconstruct a callback from a string can introduce security risks if the stored string is tampered with. Consider using a safer serialization/deserialization approach for callbacks.

window.location.reload() does not accept a URL parameter; instead, assign the URL to window.location.href. For example, replace the line with: window.location.href = consentLink.getAttribute("data-url");

Suggested change

	window.location.reload(consentLink.getAttribute("data-url"));
	window.location.href = consentLink.getAttribute("data-url");
