* Refactor BookmarkQueueSignaler to use Channel for signaling.
Replaced TaskCompletionSource with a bounded Channel to improve concurrency control and simplify the code. This change ensures better handling of multiple producers while maintaining a single reader model.
* Refactor BookmarkQueueWorker to improve resilience and clarity
Replaced Debouncer with Throttler for rate limiting and added error handling to log exceptions and ensure the worker loop continues safely while allowing proper shutdown on cancellation.
* Handle missing workflow instance during bookmark resumption
Add exception handling for `WorkflowInstanceNotFoundException` to handle cases where the workflow instance does not exist. Log a debug message and return `ResumeBookmarkResult.NotFound()` when such instances are encountered. This ensures better error management and logging for bookmark resumption.
* Refactor default initializations and rename completion methods.
Replaced `default!` with `null!` for input properties to improve clarity and consistency. Renamed methods to better reflect their purpose, changing `CheckIfCompletedAsync` to `AttemptToCompleteAsync`. These changes enhance code readability and maintainability.
* Refactor to use specific exceptions for workflow errors
Replaced generic `InvalidOperationException` with `WorkflowInstanceNotFoundException` and `WorkflowGraphNotFoundException` for improved error context. This enhances clarity and enables more precise error handling.
* Change default value of WorkflowInstanceId to null
Updated the property `WorkflowInstanceId` to use `null!` instead of `default!` to better align with nullable reference type semantics. This ensures clarity and consistency in the codebase regarding expected default values.
* Add handling for WorkflowInstanceSaved in SignalBookmarkQueueWorker
Updated the SignalBookmarkQueueWorker to implement INotificationHandler for WorkflowInstanceSaved. This ensures that workflow instance save events now trigger the bookmark queue worker, improving event handling consistency.
* Update comment to clarify bookmark and workflow instance check
Expanded the comment to explain that the queue item is stored not only when a bookmark is missing but also when the associated workflow instance is not yet in the database. This improves clarity for future maintainers regarding queuing conditions.
* Refactor TenantId string handling and nullability checks.
Moved `StringExtensions` to a common module for reuse. Updated tenant-related logic to utilize null-safe string extensions, enhancing consistency and simplifying nullability handling across the codebase.
* Set StrictMode to false by default in ObjectConverter
Modified the default value of StrictMode to `false` to enable the original flexible behavior. Developers can opt into strict mode by explicitly setting it to `true`. This change aims to enhance backward compatibility and minimize unexpected strict conversions.
* Add tenant ID retrieval to ElsaDbContextBase constructor
Retrieve the current tenant ID if available using ITenantAccessor and assign it to the TenantId property. This ensures proper handling of multi-tenancy scenarios in the database context initialization.
* Disable DbContext pooling, manual OTEL instrumentation, and strict mode.
DbContext pooling is turned off to prevent potential issues with shared context instances. Manual OpenTelemetry instrumentation is disabled to rely on automatic instrumentation instead. Strict mode is also disabled to allow more flexibility in object conversion.
* Fix infinitely waiting Alterations Workflow
Replaced workflow dispatch logic with BookmarkQueue and StimulusHasher for triggering workflows. This fixes the issue where the Alterations workflow would signal completion while a later step awaits a completion bookmark. The Bookmark Queue now handles this.
* Fix race condition and add rate limiting to bookmark queue processing
Introduce rate-limited function invocation for bookmark queue processing using ThrottleDebounce library to optimize performance. Update related classes and interfaces to support asynchronous and cancellation-aware operations, improving system responsiveness. Adjust logging to provide more detailed information during bookmark queue handling.
* Enable workflows on bug branches
This change updates the GitHub Actions workflow configuration to trigger on branches with the 'bug/*' pattern. This allows for automated actions on bug fix branches alongside the main branch, improving development and testing processes.
* Update package versions and add PrivateAssets attributes
Updated multiple package versions to the latest releases and added the `PrivateAssets="All"` attribute to several dependencies to improve project isolation. This ensures that the specified packages will not be propagated as transitive dependencies.
* Fix incorrect serializer and generator references.
Replaced `_payloadSerializer` and `_identityGenerator` with `payloadSerializer` and `identityGenerator` respectively. This resolves potential null reference issues and ensures the correct instances are used during workflow and definition processing.
* Refactor background activity scheduling logic
Moved the state commit outside of the deferred task to ensure workflow state is saved before scheduling activities. This change ensures the workflow instance is updated promptly, preventing potential concurrency issues.
* Add bookmark queue management system
Introduced a comprehensive bookmark queue system to manage and process bookmarks efficiently. This includes entities, stores, filters, processors, and workers for both in-memory and distributed environments. Additionally, added notifications to signal bookmark queue workers and updated related contracts.
* Add state commit handler with various implementations
Introduced ICommitStateHandler for committing workflow state. Provided NoopCommitStateHandler and StoreCommitStateHandler implementations. Updated namespaces and dependencies across the project to incorporate these changes.
* Fix order in CommitAsync method for proper task execution
Reorder `ExecuteDeferredTasksAsync` after `SaveAsync` in `CommitAsync` method to ensure that deferred tasks execute correctly after the state is saved, addressing potential issues with task execution dependencies.
* Remove unused and deprecated middleware and annotations
Deleted unused classes `ExecuteDeferredActivityTasks` and `ScheduleBackgroundActivitiesMiddleware`. Removed unnecessary summary tags and unused usings across multiple files to clean up the codebase.
* Remove unnecessary initial migration files
Deleted initial migration files for alterations, management, and identity contexts. These files are no longer needed and their removal helps keep the repository clean and maintainable.
* Add delay in TriggerBookmarkQueueWorker loop
Introduced a 10-second delay within the while loop of TriggerBookmarkQueueWorker. This change aims to alleviate potential tight loop issues, ensuring better performance and resource management.
* Enable all database providers in migration script
Uncomment the providers array and add previously commented database providers (SqlServer, Sqlite, PostgreSql, Oracle). This ensures compatibility with multiple database systems during the migration process.
* Remove unused Microsoft.Extensions.DependencyInjection import
The import statement for `Microsoft.Extensions.DependencyInjection` was not being utilized and has been removed. This cleanup helps in maintaining cleaner and more readable code without unnecessary imports.
* Add Dapper persistence support for bookmark queue
Introduced a new Dapper-based bookmark queue store and related classes for handling bookmark queue items. Various migrations were added to support the new `BookmarkQueueItems` table with tenant-specific columns. Refactored existing EF Core and in-memory bookmark queue item stores to use a unified interface.
* Add MongoBookmarkQueueStore implementation
Added a MongoDB-based BookmarkQueueStore to handle CRUD operations for bookmark queue items. Updated the workflow runtime persistence feature to include and utilize this new store for managing bookmark queue items.
* Add migration helper for altering columns and update keys
Introduced MigrationHelper to simplify altering DateTime and Boolean columns. Updated keys in KeyValueStore and KeyValueFilter classes to use 'Id' instead of 'Key'. Revised migration scripts to utilize the new helper methods for modifying column types.
* Prevent BookmarkQueueWorker.Stop from cancelling when not running
Previously, the Stop method would always cancel the token source regardless of the worker's state. By checking if the worker is running before cancelling, we avoid unnecessary operations and potential errors related to an already cancelled token source.
* Update database schema and bookmark handling logic
Refactored various database migration scripts to allow nullable `WorkflowInstanceId` fields and added new fields such as `ActivityInstanceId` and `CorrelationId`. Enhanced bookmark queue and bound workflow handling logic to support these new fields, ensuring precise and efficient workflow execution and queuing.
* Refactor BookmarkHash to StimulusHash and introduce ActivityTypeName
Renamed BookmarkHash to StimulusHash across multiple components and added ActivityTypeName to enhance traceability. Updated indices, filters, and entities for this change, ensuring consistent naming and improved functionality.
* Remove unnecessary timeouts in AzureServiceBusTests.
Eliminated redundant timeout parameters in _signalManager.WaitAsync calls to streamline test execution and reduce potential waiting time. This change ensures more efficient and accurate testing synchronization.
* Rename and refactor BookmarkQueueWorkerSignaler
Renamed IBookmarkQueueWorkerSignaler to IBookmarkQueueSignaler across the project for clarity. Updated related classes and methods to reflect this change. Added bookmark queue signaling to ensure new items are processed, and renamed BookmarkQueueStore to EFBookmarkQueueStore for consistency.
* Refactor EF Core stores and add migration field
Refactored EF Core store classes to simplify field usage and constructors. Added "CorrelationId" field and created corresponding index in SQLite and PostgreSQL migration files to support new functionality.
* Update workflow context ID and optimize Task handling
Added `ParentInstanceId` to `BulkDispatchWorkflowsStimulus` for context propagation. Also, reset `TaskCompletionSource` in `BookmarkQueueSignaler` to reduce memory usage and ensure proper task lifecycle management.
* Update async method signature and fix variable usage
Modified `AddAsync` to include the `OnSaveAsync` parameter. Corrected the variable used for `parentInstanceId` and utilized `ActivityTypeNameHelper` for generating type names.
* Reset migrations to 3.2
* Generate 3.3 migrations
