Bump haystack-ai from 2.5.0 to 2.30.2

[dependabot]

Bumps haystack-ai from 2.5.0 to 2.30.2.

Release notes

Sourced from haystack-ai's releases.

v2.30.2

🐛 Bug Fixes

• Fixed the Agent exiting prematurely under the default exit_conditions=["text"]. The agent now only stops when the last message is an assistant message with non-empty text (or when no tool invoker is configured). Previously, if the LLM produced an invalid tool call that was discarded, the resulting assistant message with empty text and no tool calls would trigger an exit, preventing the agent from recovering. The agent now continues looping so the model can recover on the next iteration.

v2.30.2-rc1

v2.30.1

⚡️ Enhancement Notes

• AzureOpenAIChatGenerator now accepts a Secret for the azure_endpoint and api_version parameters in addition to a plain string. This makes it possible to resolve these values from environment variables at runtime, for example with Secret.from_env_var("AZURE_OPENAI_ENDPOINT"), so the same serialized pipeline can switch between environments (e.g. dev and prod) by changing environment variables instead of the pipeline definition.

⭐️ Highlights

🐍 Syntax-aware Python code splitting with PythonCodeSplitter

The new PythonCodeSplitter is a syntax-aware splitter for Python source files, built for code-RAG and code-search pipelines where naive line-based splitting tends to cut through functions and lose structural context. It parses sources with the ast module and greedily merges units, such as module docstring, import blocks, top-level functions, class headers, methods, and nested classes, into chunks of roughly max_effective_lines, keeping whole functions and methods together. For functions that exceed oversized_factor * max_effective_lines, it falls back to a line-based secondary split with overlap.

Two options make the resulting chunks more useful downstream: strip_docstrings=True moves docstrings into chunk metadata, and preserve_class_definition=True prepends the enclosing class signature to chunks whose members live in a later chunk. Each chunk also carries rich metadata including start_line, end_line, unit_kinds, include_classes, decorators, docstrings, source_id, and split_id.

from haystack.components.preprocessors import PythonCodeSplitter
splitter = PythonCodeSplitter(
max_effective_lines=80,
strip_docstrings=True,
preserve_class_definition=True,
)
result = splitter.run(documents=[doc])

💬 Pass a plain string to any ChatGenerator

All Haystack ChatGenerator components now accept a plain string for the messages parameter in addition to a list of ChatMessage objects. The string is automatically wrapped in a ChatMessage with the user role. This makes switching from a Generator to a ChatGenerator a one-line change. The change applies to AzureOpenAIChatGenerator, AzureOpenAIResponsesChatGenerator, FallbackChatGenerator, HuggingFaceAPIChatGenerator, HuggingFaceLocalChatGenerator, OpenAIChatGenerator, and OpenAIResponsesChatGenerator, and will soon be rolled out to the ChatGenerators in Haystack Core Integrations.

from haystack.components.generators.chat import OpenAIChatGenerator
generator = OpenAIChatGenerator()
passing a string is equivalent to passing [ChatMessage.from_user("...")]
response = generator.run("What's Natural Language Processing?")
print(response["replies"][0].text)
