core[patch]: release 0.3.29 (#29017)

Resolves https://github.com/langchain-ai/langchain/issues/26918

Unit tests don't raise any additional `LangChainDeprecationWarning`.
Would like guidance on how to test this more thoroughly if needed.

Note: speed up for `bind_tools` path is shown below. This is
**redundant** with the speedup in
https://github.com/langchain-ai/langchain/pull/29015. I include it for
demonstration purposes.

-
-LCEL is a key part of LangChain, allowing you to build and organize chains of processes in a straightforward, declarative manner. It was designed to support taking prototypes directly into production without needing to alter any code. This means you can use LCEL to set up everything from basic "prompt + LLM" setups to intricate, multi-step workflows.

 ## (Optional) bootstrapping a new integration package
 
+In this section, we will outline 2 options for bootstrapping a new integration package, 
+and you're welcome to use other tools if you prefer!
+
+1. **langchain-cli**: This is a command-line tool that can be used to bootstrap a new integration package with a template for LangChain components and Poetry for dependency management.
+2. **Poetry**: This is a Python dependency management tool that can be used to bootstrap a new Python package with dependencies. You can then add LangChain components to this package.
+
+<details>
+    <summary>Option 1: langchain-cli (recommended)</summary>
+
+In this guide, we will be using the `langchain-cli` to create a new integration package
+from a template, which can be edited to implement your LangChain components.
+
+### **Prerequisites**
+
+- [GitHub](https://github.com) account
+- [PyPi](https://pypi.org/) account
+
+### Boostrapping a new Python package with langchain-cli
+
+First, install `langchain-cli` and `poetry`:
+
+```bash
+pip install langchain-cli poetry
+```
+
+Next, come up with a name for your package. For this guide, we'll use `langchain-parrot-link`.
+You can confirm that the name is available on PyPi by searching for it on the [PyPi website](https://pypi.org/).
+
+Next, create your new Python package with `langchain-cli`, and navigate into the new directory with `cd`:
+
+```bash
+langchain-cli integration new
+
+> The name of the integration to create (e.g. `my-integration`): parrot-link
+> Name of integration in PascalCase [ParrotLink]:
+
+cd parrot-link
+```
+
+Next, let's add any dependencies we need
+
+```bash
+poetry add my-integration-sdk
+```
+
+We can also add some `typing` or `test` dependencies in a separate poetry dependency group.
+
+```
+poetry add --group typing my-typing-dep
+poetry add --group test my-test-dep
+```
+
+And finally, have poetry set up a virtual environment with your dependencies, as well
+as your integration package:
+
+```bash
+poetry install --with lint,typing,test,test_integration
+```
+
+You now have a new Python package with a template for LangChain components! This
+template comes with files for each integration type, and you're welcome to duplicate or
+delete any of these files as needed (including the associated test files).
+
+To create any individual files from the [template], you can run e.g.:
+
+```bash
+langchain-cli integration new \
+    --name parrot-link \
+    --name-class ParrotLink \
+    --src integration_template/chat_models.py \
+    --dst langchain_parrot_link/chat_models_2.py
+```
+

+    <summary>Option 2: Poetry (manual)</summary>

 In this guide, we will be using [Poetry](https://python-poetry.org/) for
 dependency management and packaging, and you're welcome to use any other tools you prefer.

+    <TabItem value="tools" label="Tools">
+
+Tools are used in 2 main ways:
+
+1. To define an "input schema" or "args schema" to pass to a chat model's tool calling
+feature along with a text request, such that the chat model can generate a "tool call",
+or parameters to call the tool with.
+2. To take a "tool call" as generated above, and take some action and return a response
+that can be passed back to the chat model as a ToolMessage.
+
+The `Tools` class must inherit from the [BaseTool](https://python.langchain.com/api_reference/core/tools/langchain_core.tools.base.BaseTool.html#langchain_core.tools.base.BaseTool) base class. This interface has 3 properties and 2 methods that should be implemented in a 
+subclass.
+
+| Method/Property         | Description                                          |
+|------------------------ |------------------------------------------------------|
+| `name`                  | Name of the tool (passed to the LLM too).            |
+| `description`           | Description of the tool (passed to the LLM too).     |
+| `args_schema`           | Define the schema for the tool's input arguments.    |
+| `_run`                  | Run the tool with the given arguments.               |
+| `_arun`                 | Asynchronously run the tool with the given arguments.|
+
+### Properties
+
+`name`, `description`, and `args_schema` are all properties that should be implemented
+in the subclass. `name` and `description` are strings that are used to identify the tool
+and provide a description of what the tool does. Both of these are passed to the LLM,
+and users may override these values depending on the LLM they are using as a form of
+"prompt engineering." Giving these a concise and LLM-usable name and description is
+important for the initial user experience of the tool.
+
+`args_schema` is a Pydantic `BaseModel` that defines the schema for the tool's input
+arguments. This is used to validate the input arguments to the tool, and to provide
+a schema for the LLM to fill out when calling the tool. Similar to the `name` and
+`description` of the overall Tool class, the fields' names (the variable name) and
+description (part of `Field(..., description="description")`) are passed to the LLM, 
+and the values in these fields should be concise and LLM-usable.
+
+### Run Methods
+
+`_run` is the main method that should be implemented in the subclass. This method
+takes in the arguments from `args_schema` and runs the tool, returning a string
+response. This method is usually called in a LangGraph [`ToolNode`](https://langchain-ai.github.io/langgraph/how-tos/tool-calling/), and can also be called in a legacy
+`langchain.agents.AgentExecutor`.
+
+`_arun` is optional because by default, `_run` will be run in an async executor.
+However, if your tool is calling any apis or doing any async work, you should implement
+this method to run the tool asynchronously in addition to `_run`.
+
+### Implementation
+
+You can start from the following template or langchain-cli command:
+
+```bash
+langchain-cli integration new \
+    --name parrot-link \
+    --name-class ParrotLink \
+    --src integration_template/tools.py \
+    --dst langchain_parrot_link/tools.py

+                    .replaceAll('__MODULE_NAME__', 'PARROT_LINK')
+                    .replaceAll('__module_name__', 'langchain_parrot_link')

+
+        </details>
+
+    </TabItem>
+    <TabItem value="retrievers" label="Retrievers">
+
+Retrievers are used to retrieve documents from APIs, databases, or other sources
+based on a query. The `Retriever` class must inherit from the [BaseRetriever](https://python.langchain.com/api_reference/core/retrievers/langchain_core.retrievers.BaseRetriever.html) base class. This interface has 1 attribute and 2 methods that should be implemented in a subclass.
+
+| Method/Property         | Description                                          |
+|------------------------ |------------------------------------------------------|
+| `k`                     | Default number of documents to retrieve (configurable). |
+| `_get_relevant_documents`| Retrieve documents based on a query.                 |
+| `_aget_relevant_documents`| Asynchronously retrieve documents based on a query.  |
+
+### Attributes
+
+`k` is an attribute that should be implemented in the subclass. This attribute
+can simply be defined at the top of the class with a default value like
+`k: int = 5`. This attribute is the default number of documents to retrieve
+from the retriever, and can be overridden by the user when constructing or calling
+the retriever.
+
+### Methods
+
+`_get_relevant_documents` is the main method that should be implemented in the subclass.
+
+This method takes in a query and returns a list of `Document` objects, which have 2
+main properties:
+
+- `page_content` - the text content of the document
+- `metadata` - a dictionary of metadata about the document
+
+Retrievers are typically directly invoked by a user, e.g. as
+`MyRetriever(k=4).invoke("query")`, which will automatically call `_get_relevant_documents`
+under the hood.
+
+`_aget_relevant_documents` is optional because by default, `_get_relevant_documents` will
+be run in an async executor. However, if your retriever is calling any apis or doing
+any async work, you should implement this method to run the retriever asynchronously
+in addition to `_get_relevant_documents` for performance reasons.
+
+### Implementation
+
+You can start from the following template or langchain-cli command:
+
+```bash
+langchain-cli integration new \
+    --name parrot-link \
+    --name-class ParrotLink \
+    --src integration_template/retrievers.py \
+    --dst langchain_parrot_link/retrievers.py

+# How to add standard tests to an integration
+
+When creating either a custom class for yourself or to publish in a LangChain integration, it is important to add standard tests to ensure it works as expected. This guide will show you how to add standard tests to each integration type.
+
+## Setup
+
+First, let's install 2 dependencies:
+
+- `langchain-core` will define the interfaces we want to import to define our custom tool.
+- `langchain-tests` will provide the standard tests we want to use, as well as pytest plugins necessary to run them. Recommended to pin to the latest version: <img src="https://img.shields.io/pypi/v/langchain-tests" style={{position:"relative",top:4,left:3}} />
+
+:::note
+
+Because added tests in new versions of `langchain-tests` can break your CI/CD pipelines, we recommend pinning the 
+version of `langchain-tests` to avoid unexpected changes.
+
+:::
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+
+<Tabs>
+    <TabItem value="poetry" label="Poetry" default>
+If you followed the [previous guide](../package), you should already have these dependencies installed!
+
+```bash
+poetry add langchain-core
+poetry add --group test langchain-tests==<latest_version>
+poetry install --with test
+```
+    </TabItem>
+    <TabItem value="pip" label="Pip">
+```bash
+pip install -U langchain-core langchain-tests
+
+# install current package in editable mode
+pip install --editable .
+```
+    </TabItem>
+</Tabs>
+
+## Add and configure standard tests
+
+There are 2 namespaces in the `langchain-tests` package: 
+
+- [unit tests](../../../concepts/testing.mdx#unit-tests) (`langchain_tests.unit_tests`): designed to be used to test the component in isolation and without access to external services
+- [integration tests](../../../concepts/testing.mdx#integration-tests) (`langchain_tests.integration_tests`): designed to be used to test the component with access to external services (in particular, the external service that the component is designed to interact with).
+
+Both types of tests are implemented as [`pytest` class-based test suites](https://docs.pytest.org/en/7.1.x/getting-started.html#group-multiple-tests-in-a-class).
+
+By subclassing the base classes for each type of standard test (see below), you get all of the standard tests for that type, and you
+can override the properties that the test suite uses to configure the tests.
+
+In order to run the tests in the same way as this guide, we recommend subclassing these
+classes in test files under two test subdirectories:
+
+- `tests/unit_tests` for unit tests
+- `tests/integration_tests` for integration tests
+
+### Implementing standard tests
+
+import CodeBlock from '@theme/CodeBlock';
+
+In the following tabs, we show how to implement the standard tests for
+each component type:
+
+<Tabs>
+
+    <TabItem value="chat_models" label="Chat models">
+
+To configure standard tests for a chat model, we subclass `ChatModelUnitTests` and `ChatModelIntegrationTests`. On each subclass, we override the following `@property` methods to specify the chat model to be tested and the chat model's configuration:
+
+| Property | Description |
+| --- | --- |
+| `chat_model_class` | The class for the chat model to be tested |
+| `chat_model_params` | The parameters to pass to the chat
+model's constructor |
+
+Additionally, chat model standard tests test a range of behaviors, from the most basic requirements (generating a response to a query) to optional capabilities like multi-modal support and tool-calling. For a test run to be successful:
+
+1. If a feature is intended to be supported by the model, it should pass;
+2. If a feature is not intended to be supported by the model, it should be skipped.
+
+Tests for "optional" capabilities are controlled via a set of properties that can be overridden on the test model subclass.
+
+You can see the **entire list of configurable capabilities** in the API references for
+[unit tests](https://python.langchain.com/api_reference/standard_tests/unit_tests/langchain_tests.unit_tests.chat_models.ChatModelUnitTests.html)
+and [integration tests](https://python.langchain.com/api_reference/standard_tests/integration_tests/langchain_tests.integration_tests.chat_models.ChatModelIntegrationTests.html).
+
+For example, to enable integration tests for image inputs, we can implement
+
+```python
+@property
+def supports_image_inputs(self) -> bool:
+    return True
+```
+
+on the integration test class.
+

+Details on what tests are run, how each test can be skipped, and troubleshooting tips for each test can be found in the API references. See details:

+
+Configuring the tests consists of implementing pytest fixtures for setting up an
+empty vector store and tearing down the vector store after the test run ends.
+
+| Fixture | Description |
+| --- | --- |
+| `vectorstore` | A generator that yields an empty vector store for unit tests. The vector store is cleaned up after the test run ends. |
+
+For example, below is the `VectorStoreIntegrationTests` class for the [Chroma](https://python.langchain.com/docs/integrations/vectorstores/chroma/)
+integration:
+
+```python
+from typing import Generator
+
+import pytest
+from langchain_core.vectorstores import VectorStore
+from langchain_tests.integration_tests.vectorstores import VectorStoreIntegrationTests
+
+from langchain_chroma import Chroma
+
+
+class TestChromaStandard(VectorStoreIntegrationTests):
+    @pytest.fixture()
+    def vectorstore(self) -> Generator[VectorStore, None, None]:  # type: ignore
+        """Get an empty vectorstore for unit tests."""
+        store = Chroma(embedding_function=self.get_embeddings())
+        try:
+            yield store
+        finally:
+            store.delete_collection()
+            pass
+
+```
+
+Note that before the initial `yield`, we instantiate the vector store with an
+[embeddings](/docs/concepts/embedding_models/) object. This is a pre-defined
+["fake" embeddings model](https://python.langchain.com/api_reference/standard_tests/integration_tests/langchain_tests.integration_tests.vectorstores.VectorStoreIntegrationTests.html#langchain_tests.integration_tests.vectorstores.VectorStoreIntegrationTests.get_embeddings)
+that will generate short, arbitrary vectors for documents. You can use a different
+embeddings object if desired.
+
+In the `finally` block, we call whatever integration-specific logic is needed to
+bring the vector store to a clean state. This logic is executed in between each test
+(e.g., even if tests fail).

It can return chunks element by element or combine elements with the same metadata, with the objectives of (a) keeping related text grouped (more or less) semantically and (b) preserving context-rich information encoded in document structures. It can be used with other text splitters as part of a chunking pipeline.\n",

-    "Similar in concept to the [HTMLHeaderTextSplitter](/docs/how_to/HTML_header_metadata_splitter), the `HTMLSectionSplitter` is a \"structure-aware\" [text splitter](/docs/concepts/text_splitters/) that splits text at the element level and adds metadata for each header \"relevant\" to any given chunk.\n",
-    "\n",
-    "It can return chunks element by element or combine elements with the same metadata, with the objectives of (a) keeping related text grouped (more or less) semantically and (b) preserving context-rich information encoded in document structures.\n",
-    "\n",
-    "Use `xslt_path` to provide an absolute path to transform the HTML so that it can detect sections based on provided tags. The default is to use the `converting_to_header.xslt` file in the `data_connection/document_transformers` directory. This is for converting the html to a format/layout that is easier to detect sections. For example, `span` based on their font size can be converted to header tags to be detected as a section.\n",

+    "The `HTMLSemanticPreservingSplitter` is designed to split HTML content into manageable chunks while preserving the semantic structure of important elements like tables, lists, and other HTML components. This ensures that such elements are not split across chunks, causing loss of contextual relevancy such as table headers, list headers etc.\n",
+    "\n",
+    "This splitter is designed at its heart, to create contextually relevant chunks. General Recursive splitting with `HTMLHeaderTextSplitter` can cause tables, lists and other structered elements to be split in the middle, losing signifcant context and creating bad chunks.\n",
+    "\n",
+    "The `HTMLSemanticPreservingSplitter` is essential for splitting HTML content that includes structured elements like tables and lists, especially when it's critical to preserve these elements intact. Additionally, its ability to define custom handlers for specific HTML tags makes it a versatile tool for processing complex HTML documents.\n",

+    "**IMPORTANT**: `max_chunk_size` is not a definite maximum size of a chunk, the calculation of max size, occurs when the preserved content is not apart of the chunk, to ensure it is not split. When we add the preserved data back in to the chunk, there is a chance the chunk size will exceed the `max_chunk_size`. This is crucial to ensure we maintain the structure of the original document\n",

+       "'Certainly! Quick sort is a popular and efficient sorting algorithm that uses a divide-and-conquer approach to sort elements. Below is a simple implementation of the Quick Sort algorithm in Python:\\n\\n```python\\ndef quick_sort(arr):\\n    # Base case: if the array is empty or has one element, it\\'s already sorted\\n    if len(arr) <= 1:\\n        return arr\\n    else:\\n        # Choose a pivot element from the array\\n        pivot = arr[len(arr) // 2]\\n        \\n        # Partition the array into three parts:\\n        # - elements less than the pivot\\n        # - elements equal to the pivot\\n        # - elements greater than the pivot\\n        less_than_pivot = [x for x in arr if x < pivot]\\n        equal_to_pivot = [x for x in arr if x == pivot]\\n        greater_than_pivot = [x for x in arr if x > pivot]\\n        \\n        # Recursively apply quick_sort to the less_than_pivot and greater_than_pivot subarrays\\n        return quick_sort(less_than_pivot) + equal_to_pivot + quick_sort(greater_than_pivot)\\n\\n# Example usage:\\narr = [3, 6, 8, 10, 1, 2, 1]\\nsorted_arr = quick_sort(arr)\\nprint(\"Sorted array:\", sorted_arr)\\n```\\n\\n### Explanation:\\n1. **Base Case**: If the array has one or zero elements, it is already sorted, so we return it as is.\\n2. **Pivot Selection**: We choose the middle element of the array as the pivot. This is a simple strategy, but there are other strategies for choosing a pivot.\\n3. **Partitioning**: We partition the array into three lists:\\n   - `less_than_pivot`: Elements less than the pivot.\\n   - `equal_to_pivot`: Elements equal to the pivot.\\n   - `greater_than_pivot`: Elements greater than the pivot.\\n4. **Recursive Sorting**: We recursively sort the `less_than_pivot` and `greater_than_pivot` lists and concatenate them with the `equal_to_pivot` list to get the final sorted array.\\n\\nThis implementation is straightforward and easy to understand, but it may not be the most efficient in terms of space complexity due to the use of additional lists. For an in-place version of Quick Sort, you can modify the algorithm to sort the array within its own memory space.'"

+# CrateDB
+
+> [CrateDB] is a distributed and scalable SQL database for storing and
+> analyzing massive amounts of data in near real-time, even with complex
+> queries. It is PostgreSQL-compatible, based on Lucene, and inheriting
+> from Elasticsearch.
+
+
+## Installation and Setup
+
+### Setup CrateDB
+There are two ways to get started with CrateDB quickly. Alternatively,
+choose other [CrateDB installation options].
+
+#### Start CrateDB on your local machine
+Example: Run a single-node CrateDB instance with security disabled,
+using Docker or Podman. This is not recommended for production use.
+
+```bash
+docker run --name=cratedb --rm \
+  --publish=4200:4200 --publish=5432:5432 --env=CRATE_HEAP_SIZE=2g \
+  crate:latest -Cdiscovery.type=single-node
+```
+
+#### Deploy cluster on CrateDB Cloud
+[CrateDB Cloud] is a managed CrateDB service. Sign up for a
+[free trial][CrateDB Cloud Console].
+
+### Install Client
+Install the most recent version of the [langchain-cratedb] package
+and a few others that are needed for this tutorial.
+```bash
+pip install --upgrade langchain-cratedb langchain-openai unstructured
+```
+
+
+## Documentation
+For a more detailed walkthrough of the CrateDB wrapper, see
+[using LangChain with CrateDB]. See also [all features of CrateDB]
+to learn about other functionality provided by CrateDB.
+
+
+## Features
+The CrateDB adapter for LangChain provides APIs to use CrateDB as vector store,
+document loader, and storage for chat messages.
+
+### Vector Store
+Use the CrateDB vector store functionality around `FLOAT_VECTOR` and `KNN_MATCH`
+for similarity search and other purposes. See also [CrateDBVectorStore Tutorial].
+
+Make sure you've configured a valid OpenAI API key.
+```bash
+export OPENAI_API_KEY=sk-XJZ...
+```
+```python
+from langchain_community.document_loaders import UnstructuredURLLoader
+from langchain_cratedb import CrateDBVectorStore
+from langchain_openai import OpenAIEmbeddings
+from langchain.text_splitter import CharacterTextSplitter
+
+loader = UnstructuredURLLoader(urls=["https://github.com/langchain-ai/langchain/raw/refs/tags/langchain-core==0.3.28/docs/docs/how_to/state_of_the_union.txt"])
+documents = loader.load()
+text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
+docs = text_splitter.split_documents(documents)
+
+embeddings = OpenAIEmbeddings()
+
+# Connect to a self-managed CrateDB instance on localhost.
+CONNECTION_STRING = "crate://?schema=testdrive"
+
+store = CrateDBVectorStore.from_documents(
+    documents=docs,
+    embedding=embeddings,
+    collection_name="state_of_the_union",
+    connection=CONNECTION_STRING,
+)
+
+query = "What did the president say about Ketanji Brown Jackson"
+docs_with_score = store.similarity_search_with_score(query)
+```
+
+### Document Loader
+Load load documents from a CrateDB database table, using the document loader
+`CrateDBLoader`, which is based on SQLAlchemy. See also [CrateDBLoader Tutorial].
+
+To use the document loader in your applications:
+```python
+import sqlalchemy as sa
+from langchain_community.utilities import SQLDatabase
+from langchain_cratedb import CrateDBLoader
+
+# Connect to a self-managed CrateDB instance on localhost.
+CONNECTION_STRING = "crate://?schema=testdrive"
+
+db = SQLDatabase(engine=sa.create_engine(CONNECTION_STRING))
+
+loader = CrateDBLoader(
+    'SELECT * FROM sys.summits LIMIT 42',
+    db=db,
+)
+documents = loader.load()
+```
+
+### Chat Message History
+Use CrateDB as the storage for your chat messages.
+See also [CrateDBChatMessageHistory Tutorial].
+
+To use the chat message history in your applications:
+```python
+from langchain_cratedb import CrateDBChatMessageHistory
+
+# Connect to a self-managed CrateDB instance on localhost.
+CONNECTION_STRING = "crate://?schema=testdrive"
+
+message_history = CrateDBChatMessageHistory(
+    session_id="test-session",
+    connection=CONNECTION_STRING,
+)
+
+message_history.add_user_message("hi!")
+```
+
+### Full Cache
+The standard / full cache avoids invoking the LLM when the supplied
+prompt is exactly the same as one encountered already.
+See also [CrateDBCache Example].
+
+To use the full cache in your applications:
+```python
+import sqlalchemy as sa
+from langchain.globals import set_llm_cache
+from langchain_openai import ChatOpenAI, OpenAIEmbeddings
+from langchain_cratedb import CrateDBCache
+
+# Configure cache.
+engine = sa.create_engine("crate://crate@localhost:4200/?schema=testdrive")
+set_llm_cache(CrateDBCache(engine))
+
+# Invoke LLM conversation.
+llm = ChatOpenAI(
+    model_name="chatgpt-4o-latest",
+    temperature=0.7,
+)
+print()
+print("Asking with full cache:")
+answer = llm.invoke("What is the answer to everything?")
+print(answer.content)
+```
+
+### Semantic Cache
+
+The semantic cache allows users to retrieve cached prompts based on semantic
+similarity between the user input and previously cached inputs. It also avoids
+invoking the LLM when not needed.
+See also [CrateDBSemanticCache Example].
+
+To use the semantic cache in your applications:
+```python
+import sqlalchemy as sa
+from langchain.globals import set_llm_cache
+from langchain_openai import ChatOpenAI, OpenAIEmbeddings
+from langchain_cratedb import CrateDBSemanticCache
+
+# Configure embeddings.
+embeddings = OpenAIEmbeddings(model="text-embedding-3-small")
+
+# Configure cache.
+engine = sa.create_engine("crate://crate@localhost:4200/?schema=testdrive")
+set_llm_cache(
+    CrateDBSemanticCache(
+        embedding=embeddings,
+        connection=engine,
+        search_threshold=1.0,
+    )
+)
+
+# Invoke LLM conversation.
+llm = ChatOpenAI(model_name="chatgpt-4o-latest")
+print()
+print("Asking with semantic cache:")
+answer = llm.invoke("What is the answer to everything?")
+print(answer.content)
