Description: The lines I have changed looks like incorrectly escaped for
regex. In python 3.11, I receive DeprecationWarning for these lines.
You don't see any warnings unless you explicitly run python with `-W
always::DeprecationWarning` flag. So, this is my attempt to fix it.

Here are the warnings from log files:

```
/usr/local/lib/python3.11/site-packages/langchain/text_splitter.py:919: DeprecationWarning: invalid escape sequence '\s'
/usr/local/lib/python3.11/site-packages/langchain/text_splitter.py:918: DeprecationWarning: invalid escape sequence '\s'

Async Recursive URL loader (#8502)
Description: This PR improves the function of recursive_url_loader, such
as limiting the depth of the access, and customizable extractors(from
the raw webpage to the text of the Document object), so that users can
use other tools to extract the webpage. This PR also includes the
document and test for the new loader.
Old PR closed due to project structure change. #7756

Because socket requests are not allowed, the old unit test was removed.

Improving the text of the invalid tool to list the available tools. (#8767)
Description: When using a ReAct Agent with tools and no tool is found,
the InvalidTool gets called. Previously it just asked for a different
action, but I've found that if you list the available actions it
improves the chances of getting a valid action in the next round. I've
added a UnitTest for it also.

Support evaluating runnables and arbitrary functions (#8698)
Added a couple of "integration tests" for these that I ran.

Main design point of feedback: at this point, would it just be better to
have separate arguments for each type? Little confusing what is or isn't
supported and what is the intended usage at this point since I try to
wrap the function as runnable or pack or unpack chains/llms.

```
run_on_dataset(
...
llm_or_chain_factory = None,
llm = None,
chain = NOne,
runnable=None,
function=None
):
# raise error if none set
```

Downside with runnables and arbitrary function support is that you get
much less helpful validation and error messages, but I don't think we
should block you from this, at least.

(issue #5163) Append reminder to nest multi-prompt router prompt output in JSON markdown code block, resolving JSON parsing error. (#8709)
Resolves occasional JSON parsing error when some predictions are passed
through a `MultiPromptChain`.

Makes [this
modification](https://github.com/langchain-ai/langchain/issues/5163#issuecomment-1652220401)
to `multi_prompt_prompt.py`, which is much cleaner than appending an
entire example object, which is another community-reported solution.

add load() deserializer function that bypasses need for json serialization (#7626)
There is already a `loads()` function which takes a JSON string and
loads it using the Reviver

But in the callbacks system, there is a `serialized` object that is
passed in and that object is already a deserialized JSON-compatible
object. This allows you to call `load(serialized)` and bypass
intermediate JSON encoding.

I found one other place in the code that benefited from this
short-circuiting (string_run_evaluator.py) so I fixed that too.

Tagging @baskaryan for general/utility stuff.

Issue #8089 Improve painless script scoring with params.query_value. (#8086)
This is a minor improvement that replaces the full query_vector with the
reference string `params.query_value` used in the painless scripting

the query about half the size and much easier to read.

Issue 8081 Fix query results size bug. Other bug: pass vector_field param. (#8085)
@baskaryan
#8081 

Likely the reason why the issue occurred is that OpenSearch's default k
is 10, so it needs to be specified.

Here's a similar question about its cousin ElasticSearch

https://discuss.elastic.co/t/elasticsearch-returns-only-10-records-but-the-hit-is-507/136605

I tested this manually and also fixed the same issue in
`_default_painless_scripting_query`. In addition,
`_default_painless_scripting_query` was not passing the `vector_field`
name to a sub call, so I fixed that too.


![image](https://github.com/hwchase17/langchain/assets/32244272/cfb7aad1-f701-49d9-9beb-a723aa276817)

I also tested this in the aws opensearch developer tools.

Provides access to a Document page_content formatter in the AmazonKendraRetriever (#8034)
- Description: 
- Provides a new attribute in the AmazonKendraRetriever which processes
a ResultItem and returns a string that will be used as page_content;
- The excerpt metadata should not be changed, it will be kept as was
retrieved. But it is cleaned when composing the page_content;
    - Refactors the AmazonKendraRetriever to improve code reusability;
- Issue: #7787 
- Tag maintainer: @3coins @baskaryan
- Twitter handle: wilsonleao

**Why?**

Some use cases need to adjust the page_content by dynamically combining
the ResultItem attributes depending on the context of the item.

Fix Issue #6650: Enable Azure Active Directory token-based auth access for AzureChatOpenAI (#8622)
When using AzureChatOpenAI the openai_api_type defaults to "azure". The
utils' get_from_dict_or_env() function triggered by the root validator
does not look for user provided values from environment variables
OPENAI_API_TYPE, so other values like "azure_ad" are replaced with
"azure". This does not allow the use of token-based auth.

By removing the "default" value, this allows environment variables to be
pulled at runtime for the openai_api_type and thus enables the other
api_types which are expected to work.

This fixes #6650

This lets you pass callbacks when you create the summarize chain:

summary = summarize(documents)

Fix Async Retry Event Handling (#8659)
It fails currently because the event loop is already running.

The `retry` decorator alraedy infers an `AsyncRetrying` handler for
coroutines (see [tenacity
line](aa6f8f0a24/tenacity/__init__.py (L535)))
However before_sleep always gets called synchronously (see [tenacity
line](aa6f8f0a24/tenacity/__init__.py (L338))).


Instead, check for a running loop and use that it exists. Of course,
it's running an async method synchronously which is not _nice_. Given
how important LLMs are, it may make sense to have a task list or
something but I'd want to chat with @nfcampos on where that would live.

This PR also fixes the unit tests to check the handler is called and to
make sure the async test is run (it looks like it's just been being
skipped). It would have failed prior to the proposed fixes but passes
now.

OpenSearch supports validation using both Master Credentials (Username

argument `service` in `http_auth` and the existing code will break. To
fix this, I have updated the condition to check if service attribute is
present in http_auth before accessing it.

This adds optional `firestore_client` param to

Callback handler for Amazon SageMaker Experiments (#8587)
## Description

This PR implements a callback handler for SageMaker Experiments which is
similar to that of mlflow.
* When creating the callback handler, it takes the experiment's run
object as an argument. All the callback outputs are then logged to the
run object.
* The output of each callback action (e.g., `on_llm_start`) is saved to
S3 bucket as json file.
* Optionally, you can also log additional information such as the LLM
hyper-parameters to the same run object.
* Once the callback object is no more needed, you will need to call the
`flush_tracker()` method. This makes sure that any intermediate files
are deleted.
* A separate notebook example is provided to show how the callback is
used.

Add Support for Loading Documents from Huawei OBS (#8573)
Description:
This PR adds support for loading documents from Huawei OBS (Object
Storage Service) in Langchain. OBS is a cloud-based object storage
service provided by Huawei Cloud. With this enhancement, Langchain users
can now easily access and load documents stored in Huawei OBS directly
into the system.

Key Changes:
- Added a new document loader module specifically for Huawei OBS
integration.
- Implemented the necessary logic to authenticate and connect to Huawei
OBS using access credentials.
- Enabled the loading of individual documents from a specified bucket
and object key in Huawei OBS.
- Provided the option to specify custom authentication information or
obtain security tokens from Huawei Cloud ECS for easy access.

How to Test:
1. Ensure the required package "esdk-obs-python" is installed.
2. Configure the endpoint, access key, secret key, and bucket details
for Huawei OBS in the Langchain settings.
3. Load documents from Huawei OBS using the updated document loader
module.
4. Verify that documents are successfully retrieved and loaded into
Langchain for further processing.

Please review this PR and let us know if any further improvements are
needed. Your feedback is highly appreciated!

from my understanding, the `check_repeated_memory_variable` validator
will raise an error if any of the variables in the `memories` list are
repeated. However, the `load_memory_variables` method does not check for
repeated variables. This means that it is possible for the
`CombinedMemory` instance to return a dictionary of memory variables
that contains duplicate values. This code will check for repeated

AzureSearch Vector Store: Moving the usage of additional_fields into context of it's definition (bug fix from python error) (#8551)
Description: Using Azure Cognitive Search as a VectorStore. Calling the
`add_texts` method throws an error if there is no metadata property
specified. The `additional_fields` field is set in an `if` statement and
then is used later outside the if statement. This PR just moves the
declaration of `additional_fields` below and puts the usage of it in
context.

Issue: https://github.com/langchain-ai/langchain/issues/8544

Tagging @rlancemartin, @eyurtsev as this is related to Vector stores.

`make format`, `make lint`, `make spellcheck`, and `make test` have been
run

SQL Query Prompt update + added _execute method for SQLDatabase (#8100)
- Description: This pull request (PR) includes two minor changes:

1. Updated the default prompt for SQL Query Checker: The current prompt
does not clearly specify the final response that the LLM (Language
Model) should provide when checking for the query if `use_query_checker`
is enabled in SQLDatabase Chain. As a result, the LLM adds extra words
like "Here is your updated query" to the response. However, this causes
a syntax error when executing the SQL command in SQLDatabaseChain, as
these additional words are also included in the SQL query.

2. Moved the query's execution part into a separate method for
SQLDatabase: The purpose of this change is to provide users with more
flexibility when obtaining the result of an SQL query in the original
form returned by sqlalchemy. In the previous implementation, the run
method returned the results as a string. By creating a distinct method
for execution, users can now receive the results in original format,
which proves helpful in various scenarios. For example, during the
development of a tool, I found it advantageous to obtain results in
original format rather than a string, as currently done by the run
method.
