This commit introduces the Elsa.OpenTelemetry module to provide OpenTelemetry sources for tracing workflow and activity execution. Additionally, it updates the program to include default workflow and activity execution pipelines with tracing middleware, and improves pipeline builder extensions to support middleware insertion.
* Improve dispatched workflow input handling
Addressed input handling in dispatch messages by adding `SerializedInput` property. Also removed initialization logic and moved input deserialization to a helper method, ensuring compatibility with both new and deprecated input property formats.
* Update workflow Docker images and version tags
Changed Docker image tags from v3-2-0-rc3 to v3-2-1-preview across multiple GitHub workflows. Updated the VERSION environment variable in packages.yml to reflect the new versioning scheme. These changes ensure consistency with the new preview release.
* Update versioning to include 'preview' in package workflow
Modified the workflow to append 'preview' to the version number for non-tagged builds. This ensures clearer differentiation between stable and non-stable versions in the CI pipeline.
* Add WorkflowInstanceStorageDriver for workflow variable storage
Introduced a new storage driver, WorkflowInstanceStorageDriver, to store workflow variables directly in the workflow state. Updated relevant classes and methods to incorporate this new storage driver, ensuring seamless read/write/delete operations and extending support for it throughout the codebase.
* Refactor object conversion and update variable retrieval.
Switched from JsonObject to JsonNode for object conversion and corrected a typo in the summary comment. Changed the return type of GetVariablesDictionary method and updated its implementation to use VariablesDictionary.
* Rename 'input' to 'serializedInput' in DispatchWorkflowDefinition.
This change clarifies that the input provided to the workflow should be serialized. It enhances the readability and accuracy of the code documentation, ensuring that developers understand the expected format of the input parameter.
* Add priority and deprecation attributes to storage drivers
Introduced a priority attribute to the `IStorageDriver` interface and implemented it in various storage drivers. Additionally, marked `WorkflowStorageDriver` as deprecated and reordered storage driver listing based on priority.
* Switch MassTransit broker to in-memory and refactor converter
Changed MassTransit broker from AzureServiceBus to in-memory for improved performance in development environment. Simplified PolymorphicObjectConverterFactory by removing redundant constructor and dependencies. Removed unused folder from the project file.
Changed the target branch from 'main' to 'patch/3.2.x' in the workflow YAML files. Updated Docker image tags to specific version '3.2.0-rc3' for both elsa-server and elsa-studio.
This commit introduces two new GitHub Actions workflows: one for building and deploying the Elsa Server + Studio Docker image, and another for the Elsa Server Docker image. Both processes automate the build and push actions to Docker Hub using the latest ubuntu version and buildx for multi-platform support.
