Add multitenancy support for background tasks (#6059) * Remove initial migrations Deleted obsolete initial migration files from multiple databases: MySQL, SQL Server, SQLite, and PostgreSQL. This cleanup helps maintain a streamlined and updated migration history. * Add Document base class and create tenant-specific indices Introduced a new abstract `Document` base class to unify common properties. Implemented tenant-specific unique indices across multiple collections by including `TenantId` alongside `Id` to ensure uniqueness within tenant scopes. * Remove outdated migration files Deleted various migration files under MySql, PostgreSql, Sqlite, and SqlServer directories. This cleanup removes unnecessary schema definitions and helps to streamline the codebase. * Refactor workflow identity assignment logic Streamline workflow identity handling to ensure consistent assignment of Id, DefinitionId, and TenantId values. This change integrates tenant prefix and version suffix cleanly, enhancing clarity and maintainability. * Enable multitenancy support Added configuration for a new tenant (tenant-1) in appsettings.json and enabled multitenancy feature in Program.cs. This change allows the application to support multiple tenants, with specific configurations for each. * Refactor route table update to run as startup task Replaced `UpdateRouteTableHostedService` with `UpdateRouteTableStartupTask` to ensure route table updates are executed during application startup instead of as a hosted service. Updated configuration in `HttpFeature` and adjusted trigger validation logic in `ValidateWorkflowRequestHandler`. * Add recurring task scheduling and single-node task support. Introduce `IntervalExpressionType`, recurring task scheduling classes, and `SingleNodeTaskAttribute`. Update `RecurringTasksRunner` to handle schedules and add single-node task logic to `StartupTasksRunner`. Ensure proper namespace changes and configure sample recurring tasks. * Refactor recurring tasks scheduling system Replaced existing scheduling classes with a more modular and granular approach. Introduced new classes and interfaces like `ISchedule`, `CronSchedule`, `IntervalSchedule`, and `RecurringTaskScheduleManager`. Updated related methods and code to comply with the new design. * Refactor background task management Removed `ExpiredSecretsHostedService` and refactored it into a recurring task. Introduced `TaskExecutor` for shared task execution logic. Updated and renamed feature classes to better represent their purpose, improving task scheduling and execution management. * Add BackgroundTask abstract class to Elsa.Common module This new abstract class implements the IBackgroundTask interface with default methods for executing, starting, and stopping tasks asynchronously. It provides a basic framework for background task management in the Elsa.Common module. * Switch to CreateAsyncScope in DefaultTenantScopeFactory Updated the CreateScope method to use CreateAsyncScope instead of CreateScope. This change improves asynchronous handling of service scopes within the DefaultTenantScopeFactory class. * Add tenant handling and move StartWorkers background task Introduce ITenantAccessor in Worker class for multitenancy support. Rename and relocate StartWorkers service to BackgroundTask, ensuring smoother workflow initialization. Also, update the configuration to support Azure Service Bus connection string. * Add tenant support and refactor ProtoActor client Integrated ITenantAccessor in ProtoActorWorkflowClient class to handle multi-tenancy. Refactored methods in the client to support custom headers and added async disposable pattern in various services for proper resource management. Additionally, enabled Azure Service Bus and updated related documentation. * Add support for custom headers in ProtoActor grain methods Introduced a T4 template to generate grain methods with custom headers, enabling the use of tenant ID in requests. Updated `ProtoActorWorkflowClient` to employ these methods, removing redundant code and directly utilizing the client for various workflow operations. * Add tenant middleware to MassTransit configurations Introduced multitenancy middleware for MassTransit message handling. Added new message type `OrderReceived` and updated RabbitMQ setup in Elsa Server. Applied middleware to configure tenant data on send, publish, and consume operations. * Add new product workflow and streamline ID handling Introduced a new `RequestResponseWorkflow` for handling product requests. Simplified ID handling in `WorkflowBuilder` and `ClrWorkflowsProvider` by defaulting to empty strings and adding a version prefix. Enhanced `HttpWorkflowsMiddleware` to correctly parse full request paths. * Remove redundant files and update configuration Deleted unused files `Product.cs` and `RequestResponseWorkflow.cs` to clean up the codebase. Updated `Program.cs` configuration: switched MassTransitBroker to Memory and disabled multitenancy. * Remove MultitenantRecurringTaskService and update AzureServiceBus Removed `MultitenantRecurringTaskService` and adjusted related code for Azure Service Bus to work without it. This includes removal of tenant accessor dependency from `Worker` and cleanup of service configuration flags in `Program.cs`. * Increase signal wait timeout to 10000 milliseconds. Extended the default timeout for signal awaiting methods from 8000 to 10000 milliseconds. This change ensures more flexible and resilient waiting periods, reducing timeout occurrences in scenarios with longer processing times. * Refactor scheduling service to be a background task Renamed `CreateSchedulesHostedService` to `CreateSchedulesBackgroundTask` and refactored it to inherit from `BackgroundTask` instead of `BackgroundService`. Simplified the constructor by injecting the required dependencies directly, eliminating the need for a scoped factory. * Refactor workflow version suffix formatting Changed the version suffix format from `:v{version}` to `v{version}` and adjusted the ID concatenation accordingly. This improves consistency and readability of workflow IDs. * Enable multitenancy support in Quartz scheduler Added `TenantJobListener` to inject tenant context into jobs. Modified `QuartzWorkflowScheduler` to incorporate tenant IDs into job data maps and adjusted the configuration to acknowledge multitenancy settings. * Remove ConfigureSchedulerHostedService and TenantJobListener Consolidated tenant resolution logic into JobExecutionExtensions class. Updated ResumeWorkflowJob and RunWorkflowJob to use the new extension method for tenant retrieval. This simplifies the QuartzSchedulerFeature setup by removing the hosted service configuration. * Refactor HTTP feature and update route table task Move 'UpdateRouteTableStartupTask' from 'HostedServices' to 'Tasks' and update dependency injection configurations accordingly. Simplify 'DefaultRouteTableUpdater' by removing unnecessary options and tenant-agnostic settings from filters. * Disable multitenancy in Program.cs The useMultitenancy flag has been changed from true to false. This update affects the Elsa.Server.Web application configuration. * Simplify variable usage in HttpWorkflowsMiddleware Replaced 'fullPath' variable with 'path' to streamline code. This change enhances readability by reducing redundancy and ensures consistency in variable naming throughout the method. * Enable multitenancy and refactor tenant handling logic Enable multitenancy in the application and refactor tenant handling logic to use ITenantFinder and ITenantContextInitializer interfaces. Added header constants, updated middleware to use these interfaces, and moved extension methods to the appropriate namespace. * Add input validation to user registration form Implemented checks to ensure all required fields are filled and that input data adheres to format requirements. This change reduces errors and enhances form reliability. * Remove unused import from TenantPrefixHttpEndpointRoutesProvider This change cleans up the code by removing an unnecessary import statement. It improves code readability and reduces clutter, making future maintenance easier. The functionality remains unchanged. * Rename filter scope to "tenantPublish" in Probe method Updated the Probe method in TenantPublishMiddleware.cs to use "tenantPublish" instead of "tenantSend" for better clarity. Ensures consistency with the method's context and aligns with naming conventions. * Refactor: Remove extraneous whitespace Eliminate unnecessary whitespace in ProtoActorWorkflowClient.cs for cleaner code. This change helps maintain consistent formatting and improves readability. * Refactor DefaultRegistriesPopulator for cleaner initialization Converted constructor to use read-only fields directly, removing unnecessary instance variables. This change simplifies the code by reducing redundancy and making the constructor cleaner. 2024-10-28 18:38:24 +00:00			`namespace Elsa.Common;`
