This update introduces a new option to control synchronicity when broadcasting messages in the WorkflowInbox. The 'BroadcastWorkflowInboxMessageOptions' class allows the developer to specify whether the broadcasting will occur synchronously or asynchronously. The update also includes a new Endpoint and Workflow for demonstration and testing of this functionality.
SendHttpRequestTask was deleted and its functionality was merged into SendHttpRequestBase. This consolidation led to the addition of StatusCode and ResponseHeaders output fields in SendHttpRequestBase. Another change includes the update in FlowSendHttpRequest to indicate that it's no longer deprecated. Also, HttpHeaders class was extended to accommodate HttpResponseHeaders objects. The consolidation was done to streamline the HTTP request handling process.
This commit achieves two main goals. Firstly, it introduces two new classes called ScheduledActivity and ScheduledActivityOptions to store scheduled activities' information. Secondly, it modifies how activities are executed in the background by capturing the scheduling information as a serializable format and storing it in the workflow execution context properties dictionary. This change allows the workflow execution context to resume the activity execution context.
This commit adds the ability to manage the background execution state directly within the activity execution context. This includes adding methods to set and verify the background execution state, and modifying the existing code to use these new methods. A method for handling activity scheduling during background execution has also been started, but its implementation is not finished yet. The HTTP Request activities were updated accordingly to reflect these changes.
Significantly enhanced the capabilities of background execution of activities. Included a change in activity type of "SendHttpRequest" from 'Task' to 'Action'. Introduced new classes for handling outcomes of context in background execution. Made some necessary adjustments to HTTP Request Task to handle sending HTTP requests from a background task. Updated several middleware classes to align with these modifications.
The FlowJoin activity's join mode now includes a UIHint, which indicates its input is a dropdown. This improves user interface interaction by allowing the selection of join mode from a dropdown menu rather than manual input.
Added a non-generic version of the GetVariable method to the ExecutionContextProxy and GenerateWorkflowVariableAccessors classes in Elsa.CSharp module. Also, extended the CSharpOptions class to include additional namespaces and assemblies related to System.Text.Json. These adjustments provide a more flexible way to access workflow variables and extend the usability of JSON serialization within workflows.
Updated the HttpEndpoint class to handle non-HTTP contexts better. Instead of throwing an exception when it finds itself in a non-HTTP context, it now creates a bookmark that allows the invoker to save the state and resume execution from there. A callback has also been added to the bookmarks creation process to prepare for resumption actions.
The System.Runtime assembly and namespace has been added to CSharpOptions. This extends the functionality capabilities within the Elsa.CSharp module by providing access to the Guid class and its related methods and properties.
In the ExpressionExecutionContextExtensions module, an additional check and yield operation has been implemented. This allows the inclusion of the workflow result variable, if it exists, to the current context scope.
Added a reference to Variable.Id in the SetVariable activity within the Elsa.Workflows.Core module to ensure the correct variable scope is utilized. This change enhances the precision of the variable resolution process by ensuring the correct variable is identified and updated.
A condition has been added to check if the returnType is of type 'string'. If so, the json is returned as string directly without converting. This is particularly useful to avoid unnecessary conversion when the returnType is already a string.
Introduced HttpEndpointPathUIHandler to provide additional UI options for the Path input field in the HTTP Endpoint activity. This commits also adds SingleLineProps to offer more options for SingleLine input fields across different modules. The implementation improves UI component interactions.
This commit introduces a JSON editor UI hint to HTTP activities within Elsa Workflow. It includes creating new classes for a JSON editor options provider and a handler for this UI hint. Also, these additions are registered within the Elsa Workflow. The hint is applied to the 'RequestHeaders' and 'ResponseHeaders' input fields found in HTTP-related activity classes.
The default authorization handler for HTTP endpoints is now the AuthenticationBasedHttpEndpointAuthorizationHandler instead of the AllowAnonymousHttpEndpointAuthorizationHandler. The configuration was updated in HttpFeature.cs and the override in Program.cs was removed. This provides more security to HTTP endpoints by requiring authentication.
Changed a number of instances in both activities and UI Hints classes across multiple modules in the workflow core to utilize UIHints. The UI hint "DropDown" has been added to relevant input fields to improve the user interface. Special handling for Enum properties in the drop-down options provider has also been created.
A non-generic version of GetVariable method has been added to the ExecutionContextProxy.cs, allowing direct access to variables without specifying a type. To leverage this, Python accessors for getting and setting workflow variables have been added to GenerateWorkflowVariableAccessors.cs. This enhances the interaction between the Python scripts and the context variables.
Implemented logging in the PythonGlobalInterpreterManager class to ensure visibility during Python engine initialization and shutdown. These changes are important for spotting errors, troubleshooting issues, and understanding potential failures in Python engine initialization.
The code has been updated to provide clear and meaningful block reference names using the Humanizer library in the IdentityGraphService. The redundancy in assigning input/output Id's in both IdentityGraphService and InputJsonConverter has also been removed, resulting in cleaner, less convoluted code.
* add a more generic UIHandler to customize how inputAttributes can be handle by the ui
* Add IPropertyUIHandlerResolver and update PropertyUIHandlerResolver
Introduced a new interface, IPropertyUIHandlerResolver, to resolve UI options for a property. Refactored PropertyUIHandlerResolver to implement this interface and removed the unnecessary partial class structure. Also, cleaned up some unnecessary usings in various files for better code organization.
* Refactor variable name and description in InputDescriptor
The 'uISpecifications' variable in the InputDescriptor model is renamed to 'uiSpecifications' for better readability. Additionally, the associated comment was revised to explain that the dictionary is used by the UI.
* "Refactor codebase for improved organization and cleaner architecture"
The codebase has been significantly refactored, moving several classes to more appropriate namespaces for improved organization and cleaner architecture. This includes shifting UI hint handlers, activities, and memory-related components, amongst others. The changes should improve code readability and maintainability, but as this is a broad refactoring effort, thorough regression testing is advised.
* Add CheckList UIHint with associated handler and provider
This update introduces a new UIHint called CheckList to the Elsa.Workflows.Core. This includes the necessary handler and provider classes. The handler is registered in the WorkflowsFeature.cs, and the CheckList UIHint key has been added to the InputUIHints.cs. Various associated files have been created in both the Elsa.Api.Client and Elsa.Workflows.Core project to support this new UIHint.

Modified the GetInput methods to consider the case where the method is called within a composite activity, ensuring that only local variables have precedence over workflow input when executing within a composite activity.
Updated the WorkflowDefinitionActivityProvider code to fetch activity descriptors in a paginated manner. This change will be useful to avoid overloading system resources when interacting with large amounts of data. It retrieves a limited number of descriptors per request, looping until all are fetched.
Closes#4689
The change clears specific activity instance bookmarks in the context from the WorkflowExecutionContext. This is an extra step in the process of clearing bookmarks, which assists in managing and cleaning up workflow state effectively.
Code in several activity files and Worker.cs that involve creating bookmarks and handling messages received was refactored to improve readability and clarity. The instantiated "CreateBookmarkArgs" parameter was split into its individual arguments for improved readability. Logging in the Worker.cs file was also fine-tuned, with explicit count of workflows triggered by service bus messages being included in the debug log.
Refactoring was performed in the ActivityExecutionContext class to use object initializers for readability and clarity. This modification mainly targets the CreateBookmark and ScheduleActivityAsync methods, making their code more explicit and thus easier to understand.
The AutoComplete option has been added to the workflow bookmarks, which determines whether the activity should automatically be completed if no callback is specified. This change improves the flexibility of bookmark creation and impacts various workflow elements and procedures. The corresponding adjustments have been made at functions where bookmarks are used or created.
A Noop method has been added to the WorkflowExecutionContext, and is now assigned to the ExecuteDelegate field when no resumption point is specified. The change, will prevent the invocation of the regular "ExecuteAsync" method, closing the activity without additional operations.
The ObjectConverter file has been updated to support conversion of 'long' type. This is done by adding an additional conditional statement for checking the underlying source type for 'long', then returning the converted value.
Refactored the workflow handling logic and simplified numerous components in the codebase. Major changes include the enhancement of the Workflow Runtime handler, altering the broadcast and deliver functions in the Default Workflow Inbox, and the removal of unnecessary details in the Workflow Runtime feature. Also, unnecessary services and requests were removed for better code efficiency and readability.
The code addition includes two dependencies, IBookmarksPersister and IWorkflowStateExtractor, in the DefaultBackgroundActivityInvoker service. With these changes, during the workflow execution phase, bookmarks are captured and processed for any state changes. These modifications provide more control and efficiency over handling workflow states during the system's background operations.
The code introduces BookmarkPersister for processing bookmarks as part of the workflow runtime. This refactoring improves readability and maintainability by separating the bookmark persisting logic from the PersistBookmarkMiddleware class. A new class, BookmarkUpdater, is also added to handle updating of bookmarks. Changes also include adjustments to several other classes for improved functionality and code consistency.
The BulkDispatchWorkflows.cs activity in Elsa.Workflows.Runtime module has been updated with some key changes: Added detailed description to the input element, introduced the dispatchedInstancesCount to accurately track the number of instances dispatched, and removed some unnecessary white spaces for improved readability.
The ActivityKind property in BulkDispatchWorkflows class has been changed from Job to Task. This updates the type of activity associated with the BulkDispatchWorkflows process within the Elsa workflow runtime module.
Background activities scheduling was moved to its own middleware where the actual scheduling happens instead of in the invoking middleware. Removed ScheduleBackgroundActivities.cs handler and added ScheduleBackgroundActivitiesMiddleware.cs instead. As a part of this change, restructured BackgroundActivityInvokerMiddleware to BackgroundActivityCollectorMiddleware, and updated all relevant references.
Minor modifications to a few other files include changes in their package dependencies and activity kind settings.
Modified methods in the WorkflowInstance.cs to implement re-entrant approach for asynchronous execution. This is achieved by replacing 'await' with task-based calls passed through the Context.ReenterAfter method, providing more efficient non-blocking operations. Minor changes were also made in ClusterExtensions.cs and ProtoActorWorkflowRuntime.cs, including code clean up and slight modifications to maintain consistency.
The changes introduce a batch processing mechanism in the BulkDispatchWorkflows activity. Previously, each workflow was dispatched individually. Now, the process groups the workflows in batches, processes each batch concurrently, and handles errors. This change improves performance, particularly for large data sources.
The JavaScriptEvaluator now accepts an options parameter of type ExpressionEvaluatorOptions. This allows adding custom arguments to the evaluation context. An 'Empty' static instance of ExpressionEvaluatorOptions is added for convenience. Additionally, the usage of MassTransitAzureServiceBus in Program.cs is turned off by setting the flag to 'false'.
This commit includes new integration tests for implicit join scenarios. The tests ensure that join and parallel join activities execute correctly and complete as expected. Additionally, a change has been made to the workflow execution context to prevent duplicate activity scheduling. Now, aside from checking if the activity is already scheduled, it also checks if the activity is scheduled for the specified owner.
Fixes#4703
This commit enhances the configuration options for the MassTransit integration, providing additional settings for both Azure Service Bus and RabbitMq. It also refines the MassTransit workflow dispatcher configuration by allowing for custom dispatcher options. A default RabbitMq connection string has been added to the appsettings.json.
AzureServiceBusOption.cs and RabbitMqOptions.cs files were removed as they're no longer needed. The system now defers the configuration of MassTransit and AzureServiceBus to the application layer (Program.cs). The configuration for PrefetchCount is also allowed at the transport-level. A new abstraction, ConsumerTypeDefinition, collects all the consumer types with their respective definitions if provided. Adjustments have been made in related extension methods and classes to reflect these changes.
Removed the project reference to Elsa.Elasticsearch in Elsa.Scheduling.csproj. This reference is no longer in use and removing it simplifies the project dependencies.
This commit refactors how expression descriptors are created and retrieved across Elsa project. The asynchronous methods have been simplified to synchronous ones removing unnecessary `ValueTask` returns. Additionally, `IExpressionDescriptorRegistryPopulator` has been removed resulting in less complexity and better performance.
Removed HttpResponseHeaders class and refactored HttpRequestHeaders class into HttpHeaders. This commit merges the separate classes to represent HTTP headers into a single class, HttpHeaders. It also includes updates to the related files like HttpJavaScriptHandler and SendHttpRequestBase to reflect these changes.
* Incremental work
* Refactor code for JSON object handling and workflow context
This commit includes a significant rework of JSON object handling by ensuring produced JsonObject remains as JsonObject. Previously unimplemented customer and order workflow context providers have been removed. The test cases have been renamed and updated to confirm the new behavior is working as expected.
