The RFC 7578 spec for multipart/form-data requests does not require the
body of a request to end with a CRLF, only that each section begins with
a CRLF. While many clients implement multipart requests with the
trailing CRLF, the implementation for fetch in Node.js version 22 and
below does not.
This caused my a good number of hours debugging!
It does turn out that in September 2024 the Node.js fetch implementation
added the CRLF (https://github.com/nodejs/undici/pull/3625), though this
hasn't made it to a Node.js release yet.
This change allows the boundary to end with a newline or
not, as long as the boundary is followed by the end of the request body.
* feat: improve model input fields for huggingface component
1. Make model_id, inference_endpoint and api_token fields required
2. Convert temperature to SliderInput with range 0-2
3. Update temperature info to match HuggingFace's description

* feat(huggingface): update model selection and temperature input
This commit enhances the HuggingFace component by implementing a fixed list of
large language models in the dropdown selection and improving the temperature
input with a slider control.
Key changes in src/backend/base/langflow/components/models/huggingface.py:
- Add DEFAULT_MODEL constant set to "meta-llama/Llama-3.3-70B-Instruct"
- Replace model_id StrInput with DropdownInput containing pre-selected models:
* meta-llama/Llama-3.3-70B-Instruct (default)
* mistralai/Mixtral-8x7B-Instruct-v0.1
* mistralai/Mistral-7B-Instruct-v0.3
* meta-llama/Llama-3.1-8B-Instruct
* Qwen/Qwen2.5-Coder-32B-Instruct
* Qwen/QwQ-32B-Preview
* openai-community/gpt2
* custom option
- Add real_time_refresh to model_id dropdown for dynamic updates
- Implement custom model input field that shows/hides based on selection
- Replace temperature FloatInput with SliderInput for better UX:
* Added RangeSpec with min=0, max=2, step=0.01
* Maintains default value of 0.8
- Add build_config update logic to handle custom model visibility
- Update API URL generation to support custom model IDs
- Import RangeSpec and SliderInput from langflow packages

* [autofix.ci] apply automated fixes
* test(huggingface): update tests for enhanced model selection and UI controls
This commit updates the test suite to verify the new features and changes in
the HuggingFace component, ensuring proper functionality of the model selection
dropdown and improved temperature control.
Key changes in src/backend/tests/unit/components/models/test_huggingface.py:
- Update test_huggingface_inputs to verify new DropdownInput for model_id:
* Check DEFAULT_MODEL as default value
* Verify presence of 'custom' option
* Validate required and real_time_refresh settings
- Add verification for custom_model field:
* Confirm initial custom_model hidden state
* Verify required flag
- Add specific checks for temperature SliderInput:
* Validate default value of 0.8
* Verify RangeSpec configuration (min=0, max=2, step=0.01)
- Improve test structure with detailed assertions for field configurations
- Update imports to include DEFAULT_MODEL constant
Related to previous commit that enhanced the HuggingFace component with
fixed model list and slider controls.

* refactor: Improve file filtering in DirectoryReader
This commit improves the file filtering logic in the DirectoryReader class. Previously, it only excluded files that started with "__" and included all files that were not in a "deactivated" directory. Now, it also considers the depth of the file relative to the safe path. Only files that are one or two levels deep are included in the file list.
