🐛 fix(chat.py): catch exception when building graph and yield error message
When the flow_id is invalid, the yield statement should return an error message instead of data. Additionally, when building the graph, an exception could occur, so we added a try-except block to catch any exceptions and yield an error message instead of data.
- The radial progress now displays the percentage value correctly.
- In the build trigger, we now properly handle the end of a stream event and fixed an issue with the RadialProgressComponent when isBuilding is true.
This commit adds a value state to the RadialProgress component, replacing the progressContext previously used. It also removes the progressContext, as it is no longer needed.
The flows and tabIndex variables were not being used in the component, so they were removed. The tabId variable from the TabsContext is now being used instead to upload the file to the correct tab.
✨ feat(endpoints.py): add UploadFileResponse schema to standardize upload file response
The client_id parameter in the create_upload_file endpoint has been renamed to flow_id to improve semantics. The UploadFileResponse schema has been added to standardize the response of the create_upload_file endpoint. The response now includes the flowId and file_path fields.
✨ feat(utils.py): remove unused functions and add docstring to save_uploaded_file function
The try-except block in the create_upload_file function handles exceptions that may occur when saving uploaded files. The save_uploaded_file function now has a docstring that explains its purpose and returns the path to the saved file. The unused functions save_cache and load_cache have been removed.
The file upload functionality has been refactored to use a separate function called uploadFile, which is imported from the API controller. This improves the separation of concerns and makes the code more modular.
The uploadFile function allows the user to upload a file to the server. It takes in a file and an ID of the flow to upload the file to. The function creates a FormData object and appends the file to it. It then sends a POST request to the server with the FormData object as the body. The server responds with a Promise containing the response data.
This commit adds a new type definition for the UploadFileTypeAPI, which includes a single property file_path of type string. This type will be used to define the response of an API endpoint that handles file uploads.
✨ feat(constants.py): add default config for CTransformers
🚀 feat(llms.py): add method to format ctransformers field in LLMFrontendNode
The fix in loading.py ensures that the *kwargs are converted to a dictionary when the key contains "config". The addition of the default config for CTransformers in constants.py provides a default configuration for the CTransformers model. The new method in llms.py formats the ctransformers field in the LLMFrontendNode.
The conditional statement in the update_flow function was incorrect. The if statement was checking for the opposite of what was intended. The fix changes the if statement to check for the correct condition.
✨ feat(chat.py): add progress logging to stream_build function
The variable node was renamed to vertex to improve semantics and consistency with the naming conventions. Progress logging was added to the stream_build function to provide feedback to the user on the progress of the build process.
🐛 fix(index.tsx): fix typo in setSuccessData function call
✨ feat(index.tsx): add success logging to handleBuild function
A typo in the setSuccessData function call was fixed. Success logging was added to the handleBuild function to provide feedback to the user on the success of the build process.
The input parameter now accepts a Path object in addition to a string or dictionary. This improves the flexibility of the function and allows for easier file handling.
The `getPythonCode` function now accepts a `tweaks` parameter which is used to customize the behavior of the flow. The `buildTweaks` function is called to generate the `tweaks` object which is then passed to the `load_flow_from_json` function. This allows for more flexibility in the usage of the flow.
The fix_memory_inputs function was refactored to reduce nesting and improve readability. The function now checks if the langchain_object has a memory attribute and if it is not None before proceeding. The try-except block was also refactored to reduce nesting.
✨ feat(process.py): add input validation to process_tweaks function
The process_tweaks function has been refactored to improve readability and maintainability. The apply_tweaks function has been added to apply the tweaks to the node. The validate_input function has been added to validate the input parameters. The process_tweaks function now raises a ValueError if the input is not in the expected format.
🔀 refactor(base.py): import Chain from langchain.chains.base instead of importing it from langflow.graph.vertex.types
🔀 refactor(process.py): remove print statement from process_tweaks function
🔀 refactor(process.py): change load_flow_from_json function signature to accept optional tweaks parameter
🔀 refactor(process.py): change return type of build method in Graph class from List[Vertex] to Chain
🧪 test(loading.py): add test case for loading a flow from a JSON file and applying tweaks
🧪 test(loading.py): remove unused import statement
The import statement for Chain in base.py is now more explicit and imports it from langchain.chains.base instead of importing it from langflow.graph.vertex.types. The load_flow_from_json function in process.py now accepts either a JSON file path or a JSON object. The print statement in process_tweaks function has been removed. The load_flow_from_json function in process.py now accepts an optional tweaks parameter. The return type of the build method in the Graph class has been changed from List[Vertex] to Chain. A new test case has been added to loading.py to test loading a flow from a JSON file and applying tweaks. An unused import statement has been removed from loading.py.
✨ feat(__main__.py): add support for running Langflow on MacOS and Linux using gunicorn
The changes add support for running Langflow on Windows by using uvicorn instead of gunicorn. This is because Windows doesn't support gunicorn. The changes also add support for running Langflow on MacOS and Linux using gunicorn. This is because MacOS requires an env variable to be set to use gunicorn.
The prepare-commit-msg git hook was removed from the frontend directory. This hook was not being used and was not necessary for the project's development workflow.
The conditional statement was checking if "nodes" is in "graph_data['data']" instead of checking if "nodes" is in "graph_data". This fix ensures that the correct data is processed and avoids potential errors.
The only change in this commit is the removal of an unnecessary newline at the beginning of the file. This improves the code's readability and consistency.
🔥 chore(main.py): remove unused imports and variables
The `flow_data_store` variable in `chat.py` was missing a type hint, which was added to improve code readability and maintainability. In `main.py`, unused imports and variables were removed to improve code cleanliness.
