Added `docker/azurite-data` to the ignore list to exclude local Azurite data files from being included in the repository. Ensures proper handling of temporary files related to Azure storage emulation.
* Refactor flowchart logic and extract activity context utilities
Reorganized flowchart logic by introducing reusable extension methods for activity context operations. Moved "HasPendingWork" and "HasFaultedChildren" methods into extensions to improve readability and maintainability. Updated related flowchart logic to utilize these methods for cleaner and more modular code.
* Refactor join logic and clean up Flowchart activities
Removed obsolete `JoinKind` enum and `IJoinHintProvider` interface, replacing them with the new `JoinMode` concept. Simplified flowchart logic by consolidating flow graph handling and refining activity execution extensions. Updated `FlowJoin` to recommend property-based configuration over explicit usage.
* Avoid invalid test execution when token flow is enabled.
The added check prevents the test from running when `Flowchart.UseTokenFlow` is enabled, as this scenario is incompatible. This ensures test reliability and avoids unnecessary execution.
* Refactor token-based logic in Flowchart activity.
Simplified token handling and introduced clearer logic for WaitAny and WaitAll joins. Improved efficiency by reducing redundant checks and streamlining activity scheduling. This ensures better maintainability and functionality in complex workflows.

Updated flowchart logic to replace the previous `FlowJoinMode` with `MergeMode`, and refactored related extensions to accommodate the new enum. This enhances clarity and flexibility in workflow merging behaviors.
* Mark `FlowJoin` obsolete and enhance merge mode handling
Added the `[Obsolete]` attribute to the `FlowJoin` activity and deprecated properties to encourage using `MergeMode`. Replaced synchronous `GetMergeMode` with an asynchronous `GetMergeModeAsync` to handle legacy `FlowJoin` mappings dynamically. Other minor changes include simplifying variable initialization in `WorkflowExecutionContext`.
* Mark FlowJoin activity as obsolete
The FlowJoin activity is now marked obsolete since all activities support the MergeMode property, eliminating the need for explicit join steps. This change includes an annotation update to clearly communicate its deprecated status.
* Refactor `OnActivityCanceledAsync` method location
Moved the `OnActivityCanceledAsync` method from the `Flowchart.Counters` file to the main `Flowchart` file for improved organization and readability. This ensures the method aligns better with its primary logic and related functionality.
* Refactor flowchart logic to improve cancellation handling
Refactored `OnActivityCanceledAsync` to handle token-based flow and legacy flow separately for better clarity and maintainability. Moved `CompleteIfNoPendingWorkAsync` to a single shared location and updated pending work checks to include unconsumed tokens and faulted activities. Simplified redundant logic and ensured consistency across methods.
* Remove consumed tokens after activity completion
This update ensures that consumed tokens pointing to the completed activity are purged from the token list. This helps maintain a clean state and prevents unnecessary token accumulation during workflow processing.
* Add support for blocking tokens in flowchart activities.
Introduced a `Blocked` property to the `Token` model to prevent scheduling activities prematurely in certain merge modes. Updated token processing logic to handle blocked tokens effectively and ensure proper scheduling or consumption. Simplified token management by removing redundant methods and cleaning up consumed tokens appropriately.
* Refactor Flowchart activity cancellation logic.
Streamlined cancellation logic by separating token and counter flow handling into dedicated methods. Removed redundant properties and logic, improving readability and maintainability. Simplified `OnChildCompletedAsync` and related methods for consistency.
* Refactor token-centric flowchart execution model.
Updated the flowchart ADR to clarify the token-centric approach, including `MergeMode` rules and scheduling logic. Enhanced the model to handle loops, forks, and resumable activities more robustly while improving state management and supporting cancellation. Updated sequence diagram for clarity.
* Remove JoinMode-related methods from ActivityExtensions
The GetJoinMode and SetJoinMode methods were removed as they are no longer needed. This cleanup reduces unused code and improves maintainability of the ActivityExtensions class.
* Remove unused JoinMode enum
The JoinMode enum was determined to be unnecessary and has been deleted to clean up the codebase. This helps reduce redundancy and improve maintainability.
* Remove unused LoopbackDetector class from Flowchart module
The LoopbackDetector class was removed because it is no longer used in the codebase. Its functionality appears to be obsolete or unnecessary for the current requirements of the Flowchart module.
* Update `UseTokenFlow` to be configurable
Made `UseTokenFlow` a static field to allow external configuration. This enables users to switch between the token flow and the old counter-based model as needed. Updated documentation accordingly.
* Updated output handling of asynchronously run workflows to be the same as when run synchronously
* updated tests
* Refactor activity execution mapping and output persistence
Introduced `GetPersistableOutputAsync` in `IActivityExecutionMapper` to streamline output persistence logic. Refactored the handling of activity persistence properties, replacing repetitive code with reusable methods. Removed unused dependencies and redundant methods, optimizing code readability and maintainability.
* Remove docker-compose-datadog.yml from solution file.
The docker-compose-datadog.yml file is no longer included in the solution structure. This change cleans up unused references to ensure the solution remains consistent and up-to-date.
* Refactor workflow extensions and add new utilities
Split and reorganize workflow-related extension methods into `RunActivityExtensions` and `RunWorkflowExtensions` for better modularity. Removed deprecated methods from `ServiceProviderExtensions`. Updated tests and usages to reflect these changes.

* Add support for activity output testing
Removed obsolete test workflows and updated the If activity tests to align with simplified testing practices. Introduced `GetActivityOutput` extension for retrieving activity outputs from workflow results. Refactored related APIs to simplify execution flow and unified cancellation token handling in service methods.
* Remove unused Parlot.Fluent namespace in IfTests.cs
This commit removes an unused "using" directive for the Parlot.Fluent namespace in the IfTests.cs file. Cleaning up unused references helps maintain code clarity and reduces potential confusion.
Updated variable constructors across the codebase to use explicit names and initial values where applicable. Deprecated old constructor overloads and added new methods and overloads for better flexibility and readability. Minor cleanup includes replacing `default` keywords with `null` and streamlining code syntax.
Introduced the ability to set and persist custom names for workflow instances. Updated relevant classes, services, and tests to ensure proper handling of the `Name` property.
Extended test data in `LoopingWorkflow` to include a third item, "Item 3". Updated assertions in `Tests.cs` to validate the new expected output for the additional item.
Refactored TypeJsonConverter to distinguish and properly handle serialization of arrays and generic collections. Updated integration tests to include cases for round-tripping primitive arrays and collections for improved coverage.
Introduce a new integration test to verify workflow serialization functionality, ensuring that newly created workflow definitions can be serialized and deserialized correctly. Adjust default nullability for certain fields in `WorkflowDefinition` to improve consistency and prevent null reference issues. Minor argument update in `New` method of `WorkflowDefinitionPublisher`.
This was broken by both #5871 and #5682:
1. When a List<Guid> was serialized, it was recognized as a primitive collection and thus plainly written to the JSON without any type information: ["d4d8404c-4357-47ff-a343-649a116539f5"]
2. When this JSON was deserialized, due to lack of type info, it was deserialized as List<object>, containing strings. This is already not good.
3. When this List<object> gets serialized again (e.g. due to multiple workflow suspends causing WorkflowState serialization), this time it fails the primitive collection recognition, because object is not a primitive type. It now gets serialized as {"_items": ["d4d8404c-4357-47ff-a343-649a116539f5"], "_type": "Object[]"}
4. When that JSON gets deserialized, it tries to ReadType() but ReadType() fails to parse Object[] since it lacks the logic from TypeJsonConverter to throw away the [] before looking up Object in the WellKnownTypeRegistry, so it returns null as a type. Without a type but being faced with a json object { ... } it now deserializes into an ExpandoObject
5. Any further serialization / deserializations will now cause the expando object to get nested deeper and deeper every time.
#5682 broke serialization in two ways:
- When a generic type was being serialized, such as List`1, the ` was being escaped by JsonSerializer.Serialize to "\u0060". The PolymorphicObjectConverter would then .Trim('"') without unescaping the `, causing "\\u0060" to be written into the final json.
- When the type is generic with one type parameter, e.g. List<T>, and also IEnumerable<T>, as List<T> is, then it would append "[]" at the end of the type name, resulting in: "System.Collections.Generic.List\\u00601[[Elsa.Workflows.IntegrationTests.Serialization.JsonSerialization.WorkflowAction, Elsa.Workflows.IntegrationTests]], System.Private.CoreLib[]" which is very invalid. It may only do that, if the typename was simplified because the elementType is in the WellKnownTypeRegistry. And even then, this is questionable, as you'd be deserializing an string[] where you've serialized a List<string> for example.
