Description: added support for LangChain v0.2 for nvidia ai endpoint.
Implremented inMemory storage for chains using
RunnableWithMessageHistory which is analogous to using
`ConversationChain` which was used in v0.1 with the default
`ConversationBufferMemory`. This class is deprecated in favor of
`RunnableWithMessageHistory` in LangChain v0.2
Issue: None

**Description:**
- Updated the format for the 'Action' section in the planner prompt to
ensure it must be one of the tools without additional words. Adjusted
the phrasing from "should be" to "must be" for clarity and
enforceability.
- Corrected the tool appending logic in the
`_create_api_controller_agent` function to ensure that
`RequestsDeleteToolWithParsing` and `RequestsPatchToolWithParsing` are
properly added to the tools list for "DELETE" and "PATCH" operations.
**Issue:** #24382
**Dependencies:** None

Adds MongoDBAtlasVectorSearch to list of VectorStores compatible with
the Indexing API.
(One line change.)
As of `langchain-mongodb = "0.1.7"`, the requirements that the
VectorStore have both add_documents and delete methods with an ids kwarg
is satisfied. #23535 contains the implementation of that, and has been
merged.
Thank you for contributing to LangChain!
- [x] **PR title**: [PebbloSafeLoader] Rename loader type and add
SharePointLoader to supported loaders
- **Description:** Minor fixes in the PebbloSafeLoader:
- Renamed the loader type from `remote_db` to `cloud_folder`.
- Added `SharePointLoader` to the list of loaders supported by
PebbloSafeLoader.
- **Issue:** NA
- **Dependencies:** NA
- [x] **Add tests and docs**: NA
* Please see security warning already in existing class.
* The approach here is fundamentally insecure as it's relying on a block
approach rather than an approach based on only running allowed nodes.
So users should only use this code if its running from a properly
sandboxed environment.
### Description
Missing "stream" parameter. Without it, you'd never receive a stream of
tokens when using stream() or astream()
### Issue
No existing issue available
**Description:** : Add support for chat message history using Couchbase

2. an example notebook showing its use. It lives in

**Description:**
- Updated constructors in PyPDFParser and PyPDFLoader to handle
`extraction_mode` and additional kwargs, aligning with the capabilities
of `PageObject.extract_text()` from pypdf.
- Added `test_pypdf_loader_with_layout` along with a corresponding
example text file to validate layout extraction from PDFs.
**Issue:** fixes#19735
**Dependencies:** This change requires updating the pypdf dependency
from version 3.4.0 to at least 4.0.0.
Additional changes include the addition of a new test
test_pypdf_loader_with_layout and an example text file to ensure the
functionality of layout extraction from PDFs aligns with the new
capabilities.

# Description
This PR aims to solve a bug in `OutputFixingParser`, `RetryOutputParser`
and `RetryWithErrorOutputParser`
The bug is that the wrong keyword argument was given to `retry_chain`.
The correct keyword argument is 'completion', but 'input' is used.
This pull request makes the following changes:
1. correct a `dict` key given to `retry_chain`;
2. add a test when using the default prompt.
- `NAIVE_FIX_PROMPT` for `OutputFixingParser`;
- `NAIVE_RETRY_PROMPT` for `RetryOutputParser`;
- `NAIVE_RETRY_WITH_ERROR_PROMPT` for `RetryWithErrorOutputParser`;
3. ~~add comments on `retry_chain` input and output types~~ clarify
`InputType` and `OutputType` of `retry_chain`
# Issue
The bug is pointed out in

## Description
This pull-request improves the treatment of document IDs in
`MongoDBAtlasVectorSearch`.
Class method signatures of add_documents, add_texts, delete, and
from_texts
now include an `ids:Optional[List[str]]` keyword argument permitting the
user
greater control.
Note that, as before, IDs may also be inferred from
`Document.metadata['_id']`
if present, but this is no longer required,
IDs can also optionally be returned from searches.
This PR closes the following JIRA issues.
* [PYTHON-4446](https://jira.mongodb.org/browse/PYTHON-4446)
MongoDBVectorSearch delete / add_texts function rework
* [PYTHON-4435](https://jira.mongodb.org/browse/PYTHON-4435) Add support
for "Indexing"
* [PYTHON-4534](https://jira.mongodb.org/browse/PYTHON-4534) Ensure
datetimes are json-serializable

- Description: When SQLDatabase.from_databricks is ran from a Databricks
Workflow job, line 205 (default_host = context.browserHostName) throws
an ``AttributeError`` as the ``context`` object has no
``browserHostName`` attribute. The fix handles the exception and sets
the ``default_host`` variable to null

**Description:** At the moment neo4j wrapper is using setVectorProperty,
which is deprecated
([link](https://neo4j.com/docs/operations-manual/5/reference/procedures/#procedure_db_create_setVectorProperty)).
I replaced with the non-deprecated version.
Neo4j recently introduced a new cypher method to associate embeddings
into relations using "setRelationshipVectorProperty" method. In this PR
I also implemented a new method to perform this association maintaining
the same format used in the "add_embeddings" method which is used to
associate embeddings into Nodes.
I also included a test case for this new method.
Description: added support for LangChain v0.2 for PipelineAI
integration. Removed deprecated classes and incorporated support for
LangChain v0.2 to integrate with PipelineAI. Removed LLMChain and
replaced it with Runnable interface. Also added StrOutputParser, that
parses LLMResult into the top likely string.
Issue: None
Dependencies: None.
