Automated refresh of model profile data for all in-monorepo partner
integrations via `langchain-profiles refresh`.

`test_no_overrides_DO_NOT_OVERRIDE` only treated an override as valid
when the method itself carried an `@pytest.mark.xfail(reason=...)`.
Overrides that re-parametrize a standard test and xfail only a subset of
cases via `pytest.param(..., marks=pytest.mark.xfail(...))` were
rejected.
Loosen the xAI integration tests to handle two recent provider
behaviors: `web_search` responses may now include block types beyond the
core trio, and streaming aggregation under `output_version="v1"` does
not produce a `tool_call` content block (tool calls are only available
on `.tool_calls`).
Bumps the `langchain-tests` minimum across the monorepo from `1.0.0` to
`1.1.9` and adds a partner-level `Makefile` so partner lockfiles can be
regenerated in one command, matching the existing convention under
`libs/`.
Reasoning-emitting chat models return `[reasoning, text]` content blocks
where vanilla models return `[text]`. The shared streaming integration
tests asserted exactly one block, which fails when reasoning blocks are
returned when streaming is otherwise correct.
Relaxed to assert text presence without touching the lifecycle,
`chunk_position`, or `output_version` checks.
Adds a `transformers` attribute to `AgentMiddleware` so middleware can
declare scope-aware `StreamTransformer` factories alongside their
`tools` and lifecycle hooks. `create_agent` merges middleware-registered
factories with any caller-supplied ones at compile time.
## API
```python
class MyMiddleware(AgentMiddleware):
transformers = (MyTransformer,) # factory: (scope,) -> StreamTransformer
```
When the agent compiles, the final transformer order on the run mux is:
1. Built-in ``ToolCallTransformer``
2. Middleware-registered factories, in middleware order
3. Caller-supplied ``transformers=`` from ``create_agent``
This ordering keeps the built-in tool-call projection in front of any
consumer transformers and gives caller-supplied entries the final word.
`ChatFireworks` previously left `max_retries` at `None` (single attempt)
and only retried `APITimeoutError`. When the Fireworks edge drops TCP
without an HTTP response, the SDK wraps `httpx.RequestError` as a bare
`APIConnectionError`, which slipped past the retry decorator. Aligning
the default with the Fireworks SDK and `langchain-openai`
(`max_retries=2`) and broadening the retryable parent class closes both
gaps.
Fireworks integration tests have been flaky against the live API with
429s. Adds a shared, xdist-aware rate limiter and a global retry policy
so transient rate-limit errors no longer fail the suite. Mirrors the
same fix recently applied to `langchain-mistralai`.
Two unrelated nightly-CI failures rooted in upstream API drift. OpenAI
retired `gpt-4o-audio-preview` (now 404) and Azure embedding deployments
running `text-embedding-3-*` with truncated `dimensions` no longer
return unit-norm vectors.
Mistral integration tests have been flaky against the live API. This
adds a shared, xdist-aware rate limiter and a global retry policy so
transient 429s no longer fail the suite.
Closes#37172
---
Bumps `langchain-fireworks` to the rewritten `fireworks-ai` 1.x SDK
(currently 1.2.0a*; Stainless-generated, pure-httpx, no
`grpcio`/`protobuf`/`googleapis-common-protos`).
The motivating bug is a startup crash in self-hosted LangGraph
environments that also import `langchain-google-vertexai`. Importing
`fireworks-ai` 0.19.x eagerly loads vendored grpcio protobuf modules
under `fireworks.control_plane.generated.protos_grpcio.*`, which
register `google/rpc/status.proto`, `google/api/*.proto`, and
`google/longrunning/*.proto` in the default protobuf descriptor pool.
When `langchain-google-vertexai` later triggers
`google.api_core.exceptions` → `grpc_status.rpc_status` →
`google.rpc.status_pb2`, the pool already holds a byte-different
descriptor for `google/rpc/status.proto` and startup dies with:
```
TypeError: Couldn't build proto file into descriptor pool:
duplicate file name google/rpc/status.proto
```
Fleet has been pinning around this by routing Fireworks through
`ChatOpenAI` against the OpenAI-compat endpoint, which works for
inference but means Fireworks `ModelProfile` data never loads — so Kimi
K2.6's ~262k context window goes unrecognized and summarization triggers
below limit.
The 1.x SDK does not vendor protobuf at all. The control-plane gRPC code
path is gone; chat inference goes over httpx. Verified locally that
`import langchain_fireworks` and `from langchain_fireworks import
ChatFireworks` load zero `_pb2` / `google.*` modules.
## What changed in `ChatFireworks`
- Imports switch from `fireworks.client` to the top-level `fireworks`
package.
- Async path now `await client.chat.completions.create(...)`; the 0.x
`acreate` shim is no longer used.
- Error classes remapped to the 1.x hierarchy. `InvalidRequestError` →
`BadRequestError`. `BadGatewayError` and `ServiceUnavailableError` no
longer exist (1.x maps all `>=500` to `InternalServerError`) and were
dropped from the retryable set with no loss of coverage.
`FireworksContextOverflowError`'s parent class becomes
`BadRequestError`.
- `stream_options` is moved into the SDK's `extra_body` because the
Stainless-generated `create()` signature does not model it as a typed
kwarg. Top-level `stream_options` is preserved as a caller convenience;
if a caller supplies both `extra_body["stream_options"]` and a top-level
value, `extra_body` wins and the discarded value is logged.
- The 0.x `(connect, read)` tuple form of `request_timeout` is
normalized to an `httpx.Timeout` so existing user code keeps working.
- The SDK's built-in retry layer is suppressed via `max_retries=0` on
client construction so retries remain owned by
`create_base_retry_decorator` and surface through the LangChain
`run_manager`.
## Lifecycle methods
Adds `close()` and `aclose()` on `ChatFireworks`. The 1.x
`AsyncFireworks` client defaults to `httpx_aiohttp.HttpxAiohttpClient`,
whose underlying aiohttp `ClientSession` is created lazily on first
request. Sync-only paths therefore never open a session — which fixes
the "Unclosed client session" warnings from #37172 at the source.
Callers using async paths can now release the connector
deterministically rather than relying on GC after the event loop has
stopped. An autouse fixture in the integration `conftest.py` calls
`aclose()` between tests to silence the corresponding `Unclosed
connector` warning that surfaces under `pytest-asyncio`.
## Relation to #37227
Supersedes #37227. That PR monkey-patched
`fireworks._util.is_running_in_async_context` and
`fireworks.client.api_client.is_running_in_async_context` to suppress
the 0.x SDK's eager `aiohttp.ClientSession` creation in async contexts.
Both module paths are removed in 1.x; the SDK's lazy-session behavior
makes the suppression unnecessary, and the explicit `aclose()` provides
the cleaner long-term lifecycle hook. Thanks to @keenborder786 for
surfacing the failure mode.
## Installation note
`fireworks-ai` 1.x is currently published as an alpha (`1.2.0a*`); a
stable 1.x is not yet out. `pip install langchain-fireworks` / `uv pip
install langchain-fireworks` will need `--pre` (or `--prerelease=allow`)
until Fireworks GAs 1.x. The `pyproject.toml` adds `[tool.uv] prerelease
= "allow"` so the in-repo dev environment resolves cleanly. The package
version is bumped to `1.4.0` — the public surface (`ChatFireworks`,
`Fireworks`, `FireworksEmbeddings`) is unchanged; the breakage is
confined to internal error classes and the transitive SDK.

Same shape as the merged anthropic patch in #37064, ported to
`libs/partners/openai`.
`_SyncHttpxClientWrapper.__del__` / `_AsyncHttpxClientWrapper.__del__`
check `self.is_closed`, which reads `self._state`. When a wrapper is
created without `__init__` running to completion — `copy.deepcopy` via
`__new__` + `__setstate__`, or a constructor that raised partway through
— `_state` is missing and the finalizer prints
```
Exception ignored in: <function _SyncHttpxClientWrapper.__del__ at 0x...>
Traceback (most recent call last):
File ".../langchain_openai/chat_models/_client_utils.py", line 366, in __del__
if self.is_closed:
File ".../httpx/_client.py", line 228, in is_closed
return self._state == ClientState.CLOSED
AttributeError: '_SyncHttpxClientWrapper' object has no attribute '_state'
```
at GC time. Same noise pattern that #37064 fixed for the anthropic
partner.
Hoist the `is_closed` access inside the existing `try/except` so the
`AttributeError` is swallowed alongside the `close()` / `aclose()`
exceptions that block already handles.
Tests: two new unit tests build the wrappers via `__new__` (no
`__init__` → no `_state`) and call `__del__` directly, mirroring the
tests added in #37064.
Verified:
- `cd libs/partners/openai && make format` -> all checks passed
- `cd libs/partners/openai && make test
TEST_FILE=tests/unit_tests/chat_models/test_client_utils.py` -> 37
passed, 1 skipped (linux-only)
- `cd libs/partners/openai && make lint` -> all checks passed, mypy
clean

changelog</a>.</em></p>
<blockquote>
<h2>3.15 (2026-05-12)</h2>
<ul>
<li>Enforce DNS-length cap on individual labels early in
<code>check_label</code>,
short-circuiting contextual-rule processing for oversized input
while staying compatible with UTS 46 usage.</li>
<li>Tidy core helpers: hoist bidi category sets to module-level
frozensets (avoiding per-codepoint list construction), simplify
length checks, and reuse the shared <code>_unicode_dots_re</code> from
<code>idna.core</code> in the codec module.</li>
<li>Use <code>raise ... from err</code> for proper exception chaining
and
switch internal string formatting to f-strings.</li>
<li>Allow <code>flit_core</code> 4.x in the build backend.</li>
<li>Expand the ruff lint set (flake8-bugbear, flake8-simplify,
pyupgrade, perflint) and apply the surfaced fixes; pin lint CI
to Python 3.14.</li>
<li>Add Dependabot configuration for GitHub Actions.</li>
<li>Convert README and HISTORY from reStructuredText to Markdown.</li>
<li>Reference CVE-2026-45409 for the 3.14 advisory in place of the
initial GHSA identifier.</li>
</ul>
<p>Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for
contributions to this release.</p>
<h2>3.14 (2026-05-10)</h2>
<ul>
<li>Removed opportunity to process long inputs into quadratic
time by rejecting oversize inputs up-front. Closes a bypass
of the CVE-2024-3651 mitigation. [CVE-2026-45409]</li>
</ul>
<p>Thanks to Stan Ulbrych for reporting the issue.</p>
<h2>3.13 (2026-04-22)</h2>
<ul>
<li>Correct classification error for codepoint U+A7F1</li>
</ul>
<h2>3.12 (2026-04-21)</h2>
<ul>
<li>Update to Unicode 17.0.0.</li>
<li>Issue a deprecation warning for the transitional argument.</li>
<li>Added lazy-loading to provide some performance improvements.</li>
<li>Removed vestiges of code related to Python 2 support, including
segmentation of data structures specific to Jython.</li>
</ul>
<p>Thanks to Rodrigo Nogueira for contributions to this release.</p>
<h2>3.11 (2025-10-12)</h2>
<ul>
<li>Update to Unicode 16.0.0, including significant changes to UTS46
processing. As a result of Unicode ending support for it, transitional
processing no longer has an effect and returns the same result.</li>

<blockquote>
<h2>3.15 (2026-05-12)</h2>
<ul>
<li>Enforce DNS-length cap on individual labels early in
<code>check_label</code>,
short-circuiting contextual-rule processing for oversized input
while staying compatible with UTS 46 usage.</li>
<li>Tidy core helpers: hoist bidi category sets to module-level
frozensets (avoiding per-codepoint list construction), simplify
length checks, and reuse the shared <code>_unicode_dots_re</code> from
<code>idna.core</code> in the codec module.</li>
<li>Use <code>raise ... from err</code> for proper exception chaining
and
switch internal string formatting to f-strings.</li>
<li>Allow <code>flit_core</code> 4.x in the build backend.</li>
<li>Expand the ruff lint set (flake8-bugbear, flake8-simplify,
pyupgrade, perflint) and apply the surfaced fixes; pin lint CI
to Python 3.14.</li>
<li>Add Dependabot configuration for GitHub Actions.</li>
<li>Convert README and HISTORY from reStructuredText to Markdown.</li>
<li>Reference CVE-2026-45409 for the 3.14 advisory in place of the
initial GHSA identifier.</li>
</ul>
<p>Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for
contributions to this release.</p>
<h2>3.14 (2026-05-10)</h2>
<ul>
<li>Removed opportunity to process long inputs into quadratic
time by rejecting oversize inputs up-front. Closes a bypass
of the CVE-2024-3651 mitigation. [CVE-2026-45409]</li>
</ul>
<p>Thanks to Stan Ulbrych for reporting the issue.</p>
<h2>3.13 (2026-04-22)</h2>
<ul>
<li>Correct classification error for codepoint U+A7F1</li>
</ul>
<h2>3.12 (2026-04-21)</h2>
<ul>
<li>Update to Unicode 17.0.0.</li>
<li>Issue a deprecation warning for the transitional argument.</li>
<li>Added lazy-loading to provide some performance improvements.</li>
<li>Removed vestiges of code related to Python 2 support, including
segmentation of data structures specific to Jython.</li>
</ul>
<p>Thanks to Rodrigo Nogueira for contributions to this release.</p>
<h2>3.11 (2025-10-12)</h2>
<ul>
<li>Update to Unicode 16.0.0, including significant changes to UTS46
processing. As a result of Unicode ending support for it, transitional
processing no longer has an effect and returns the same result.</li>

<li>Enforce DNS-length cap on individual labels early in

short-circuiting contextual-rule processing for oversized input

<li>Tidy core helpers: hoist bidi category sets to module-level
frozensets (avoiding per-codepoint list construction), simplify
length checks, and reuse the shared <code>_unicode_dots_re</code> from
<code>idna.core</code> in the codec module.</li>
<li>Use <code>raise ... from err</code> for proper exception chaining
and
switch internal string formatting to f-strings.</li>
<li>Allow <code>flit_core</code> 4.x in the build backend.</li>
<li>Expand the ruff lint set (flake8-bugbear, flake8-simplify,
pyupgrade, perflint) and apply the surfaced fixes; pin lint CI

Bumps [idna](https://github.com/kjd/idna) from 3.10 to 3.15.

<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/kjd/idna/blob/master/HISTORY.md">idna's
changelog</a>.</em></p>
<blockquote>
<h2>3.15 (2026-05-12)</h2>
<ul>
<li>Enforce DNS-length cap on individual labels early in
<code>check_label</code>,
short-circuiting contextual-rule processing for oversized input
while staying compatible with UTS 46 usage.</li>
<li>Tidy core helpers: hoist bidi category sets to module-level
frozensets (avoiding per-codepoint list construction), simplify
length checks, and reuse the shared <code>_unicode_dots_re</code> from
<code>idna.core</code> in the codec module.</li>
<li>Use <code>raise ... from err</code> for proper exception chaining
and
switch internal string formatting to f-strings.</li>
<li>Allow <code>flit_core</code> 4.x in the build backend.</li>
<li>Expand the ruff lint set (flake8-bugbear, flake8-simplify,
pyupgrade, perflint) and apply the surfaced fixes; pin lint CI
to Python 3.14.</li>
<li>Add Dependabot configuration for GitHub Actions.</li>
<li>Convert README and HISTORY from reStructuredText to Markdown.</li>
<li>Reference CVE-2026-45409 for the 3.14 advisory in place of the
initial GHSA identifier.</li>
</ul>
<p>Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for
contributions to this release.</p>
<h2>3.14 (2026-05-10)</h2>
<ul>
<li>Removed opportunity to process long inputs into quadratic
time by rejecting oversize inputs up-front. Closes a bypass
of the CVE-2024-3651 mitigation. [CVE-2026-45409]</li>
</ul>
<p>Thanks to Stan Ulbrych for reporting the issue.</p>
<h2>3.13 (2026-04-22)</h2>
<ul>
<li>Correct classification error for codepoint U+A7F1</li>
</ul>
<h2>3.12 (2026-04-21)</h2>
<ul>
<li>Update to Unicode 17.0.0.</li>
<li>Issue a deprecation warning for the transitional argument.</li>
<li>Added lazy-loading to provide some performance improvements.</li>
<li>Removed vestiges of code related to Python 2 support, including
segmentation of data structures specific to Jython.</li>
</ul>
<p>Thanks to Rodrigo Nogueira for contributions to this release.</p>
