<!-- Thank you for your contribution! Please review https://microsoft.github.io/autogen/docs/Contribute before opening a pull request. --> <!-- Please add a reviewer to the assignee section when you create a PR. If you don't have the access to it, we will shortly find a reviewer and assign them to your PR. --> ## Why are these changes needed? ## Prevent Async Event Loop from Running Indefinitely ### Description This pull request addresses a bug in the python/packages/autogen-core/src/autogen_core/_single_threaded_agent_runtime.py `async send_message` function where messages were being queued for recipients that were not recognized. The current implementation sets an exception on the future object when the recipient is not found, but continues to enqueue the message, potentially leading to inconsistent states. ### Changes Made - Added a return statement immediately after setting the exception when the recipient is not found. This ensures that the function exits early, preventing further processing of the message and avoiding unnecessary operations. - This fix also addresses an issue where the asynchronous event loop could potentially continue running indefinitely without terminating, due to the future not being properly handled when an unknown recipient is encountered. ### Impact This fix prevents messages from being sent to unknown recipients. It also ensures that the event loop can terminate correctly without being stuck in an indefinite state. ### Testing Ensure that the function correctly handles cases where the recipient is not recognized by returning the exception without enqueuing the message, and verify that the event loop terminates as expected. <!-- Please give a short summary of the change and the problem this solves. --> ## Related issue number <!-- For example: "Closes #1234" --> ## Checks - [ ] I've included any doc changes needed for <https://microsoft.github.io/autogen/>. See <https://github.com/microsoft/autogen/blob/main/CONTRIBUTING.md> to build and test documentation locally. - [ ] I've added tests (if relevant) corresponding to the changes introduced in this PR. - [ ] I've made sure all auto checks have passed.

AutoGen Python packages
This directory works as a single uv workspace containing all project packages. See packages to discover all project packages.
Migrating from 0.2.x?
Please refer to the migration guide for how to migrate your code from 0.2.x to 0.4.x.
Development
TL;DR, run all checks with:
uv sync --all-extras
source .venv/bin/activate
poe check
Setup
uv is a package manager that assists in creating the necessary environment and installing packages to run AutoGen.
Note: To prevent incompatibilities between versions the same UV version as is running in CI should be used. Check the version in CI by looking the setup-uv action, here for example.
For example, to change your version to 0.5.18, run:
uv self update 0.5.18
Virtual Environment
During development, you may need to test changes made to any of the packages.
To do so, create a virtual environment where the AutoGen packages are installed based on the current state of the directory.
Run the following commands at the root level of the Python directory:
uv sync --all-extras
source .venv/bin/activate
uv sync --all-extraswill create a.venvdirectory at the current level and install packages from the current directory along with any other dependencies. Theall-extrasflag adds optional dependencies.source .venv/bin/activateactivates the virtual environment.
Common Tasks
To create a pull request (PR), ensure the following checks are met. You can run each check individually:
- Format:
poe format - Lint:
poe lint - Test:
poe test - Mypy:
poe mypy - Pyright:
poe pyright - Build docs:
poe --directory ./packages/autogen-core/ docs-build - Auto rebuild+serve docs:
poe --directory ./packages/autogen-core/ docs-serve - Check samples in
python/samples:poe samples-code-checkAlternatively, you can run all the checks with: poe check
Note
These need to be run in the virtual environment.
Syncing Dependencies
When you pull new changes, you may need to update the dependencies.
To do so, first make sure you are in the virtual environment, and then in the python directory, run:
uv sync --all-extras
This will update the dependencies in the virtual environment.
Creating a New Package
To create a new package, similar to autogen-core or autogen-chat, use the following:
uv sync --python 3.12
source .venv/bin/activate
cookiecutter ./templates/new-package/
