- Keep **kwargs approach (no exec()) for security
- Integrate path traversal validation from main branch
- Add URL encoding for path parameters
- Merge both test suites (edge cases + security tests)
- All 14 tests passing
- Move BaseBatchesConfig, BaseContainerConfig, BaseEmbeddingConfig, BaseImageEditConfig, BaseImageGenerationConfig, BaseImageVariationConfig, BasePassthroughConfig, BaseRealtimeConfig, BaseRerankConfig, BaseVectorStoreConfig, BaseVectorStoreFilesConfig, BaseVideoConfig to lazy loading

- Move Rules, AsyncHTTPHandler, HTTPHandler to lazy loading via __getattr__
- Move get_num_retries_from_retry_policy, reset_retry_policy to lazy loading
- Move get_secret to lazy loading

- Move core_helpers functions (get_litellm_metadata_from_kwargs, map_finish_reason, process_response_headers) to lazy loading
- Move dot_notation_indexing functions (delete_nested_value, is_nested_path) to lazy loading

- Update Rules() instantiation in client decorator to use getattr for lazy loading
- Update Rules.has_pre_call_rules() usage in function_setup to use getattr

- Update get_litellm_logging_class() usage in function_setup to use getattr for lazy loading
- Fixes NameError: name 'get_litellm_logging_class' is not defined error that occurs when get_litellm_logging_class is lazy-loaded
* fix(utils): use getattr for get_set_callbacks in function_setup
- Update get_set_callbacks() usage in function_setup to use getattr for lazy loading
- Fixes NameError: name 'get_set_callbacks' is not defined error that occurs when get_set_callbacks is lazy-loaded

- Update update_response_metadata (4 occurrences) to use getattr
- Update executor.submit (1 occurrence) to use getattr
- Update get_num_retries_from_retry_policy (2 occurrences) to use getattr
- Update reset_retry_policy (2 occurrences) to use getattr
- Update is_nested_path and delete_nested_value (1 occurrence each) to use getattr
- Update _ensure_extra_body_is_safe (1 occurrence) to use getattr
Fixes NameError errors that occur when these functions/classes are lazy-loaded but used directly in utils.py
* fix(utils): use getattr for _get_base_model_from_litellm_call_metadata in _get_base_model_from_metadata
- Update _get_base_model_from_litellm_call_metadata usage to use getattr for lazy loading
- Fixes NameError: name '_get_base_model_from_litellm_call_metadata' is not defined
* fix(utils): use getattr for second _get_base_model_from_litellm_call_metadata usage
- Fix the second occurrence of _get_base_model_from_litellm_call_metadata on line 7052
- Both occurrences in _get_base_model_from_metadata now use getattr for lazy loading
* fix(utils): fix indentation in _get_base_model_from_metadata function
* fix(utils): use getattr for get_litellm_metadata_from_kwargs in _get_litellm_params
- Update get_litellm_metadata_from_kwargs usage to use getattr for lazy loading
- Fixes NameError: name 'get_litellm_metadata_from_kwargs' is not defined
* fix(utils): fix syntax error in get_litellm_metadata_from_kwargs fix
- Move getattr call before cast statement to fix syntax error
* refactor(utils): lazy load redact_messages imports to improve import time
- Move LiteLLMLoggingObject and redact_message_input_output_from_logging to lazy loading via __getattr__
- Add type stubs in TYPE_CHECKING block for mypy type checking
- These are only used in type annotations (with from __future__ import annotations), so lazy loading works correctly
This reduces import time by deferring the redact_messages module import until these are actually accessed.
* refactor(utils): lazy load CustomStreamWrapper to improve import time
- Move CustomStreamWrapper from streaming_handler to lazy loading via __getattr__
- Add type stub in TYPE_CHECKING block for mypy type checking
- CustomStreamWrapper is not used internally in utils.py, only exported for other modules
This reduces import time by deferring the streaming_handler module import until CustomStreamWrapper is actually accessed.
* refactor(utils): lazy load BaseGoogleGenAIGenerateContentConfig to improve import time
- Move BaseGoogleGenAIGenerateContentConfig from google_genai.transformation to lazy loading via __getattr__
- Add type stub in TYPE_CHECKING block for mypy type checking
- BaseGoogleGenAIGenerateContentConfig is only used in type annotations (with from __future__ import annotations), so lazy loading works correctly
This reduces import time by deferring the google_genai.transformation module import until BaseGoogleGenAIGenerateContentConfig is actually accessed.
* refactor(utils): lazy load BaseOCRConfig, BaseSearchConfig, and BaseTextToSpeechConfig
- Move BaseOCRConfig, BaseSearchConfig, and BaseTextToSpeechConfig to lazy loading via __getattr__
- Add type stubs in TYPE_CHECKING block for mypy type checking
- These config classes are only used in quoted type annotations (forward references), so lazy loading works correctly
This reduces import time by deferring the transformation module imports until these config classes are actually accessed.
* refactor(utils): lazy load BedrockModelInfo, CohereModelInfo, and MistralOCRConfig
- Move BedrockModelInfo, CohereModelInfo, and MistralOCRConfig to lazy loading via __getattr__
- Add type stubs in TYPE_CHECKING block for mypy type checking
- Update internal usages to use getattr pattern for accessing lazy-loaded classes
- These provider-specific model info classes are only used in specific code paths, so lazy loading reduces initial import time
This reduces import time by deferring the bedrock, cohere, and mistral module imports until these classes are actually accessed.
* fix(utils): remove duplicate MistralOCRConfig import in TYPE_CHECKING block
* refactor(utils): lazy load heavy imports to improve import time
- Move BaseVectorStore, CredentialAccessor, and exception_mapping_utils imports to lazy loading via __getattr__
- Add _get_utils_globals() helper function following pattern from _lazy_imports.py
- Refactor __getattr__ to use consistent caching pattern matching __init__.py
- Update load_credentials_from_list to use lazy-loaded CredentialAccessor
This reduces import time and memory usage by only loading these modules when they're actually accessed, not during module import.
* refactor(utils): lazy load additional heavy imports to improve import time
- Move get_llm_provider, _is_non_openai_azure_model to lazy loading
- Move get_supported_openai_params to lazy loading
- Move convert_dict_to_response functions (LiteLLMResponseObjectHandler, convert_to_model_response_object, etc.) to lazy loading
- Move get_api_base and ResponseMetadata to lazy loading
- Move _parse_content_for_reasoning to lazy loading
- Update all internal usages to access via getattr(sys.modules[__name__], ...)
This reduces import time and memory usage by only loading these modules when they're actually accessed, not during module import.
* fix(utils): suppress PLR0915 linter warning for __getattr__ function
The __getattr__ function intentionally has many statements to handle
multiple lazy-loaded imports. Add noqa comment to suppress the warning.
* fix(utils): add type stubs for lazy-loaded functions in TYPE_CHECKING block
Add type imports and declarations in TYPE_CHECKING block to help mypy
understand the types of lazy-loaded functions accessed via __getattr__.
This follows the same pattern used in __init__.py for lazy-loaded items.
