 		d8b7800183 chore(langgraph): use two phase read to avoid unnecessary data transport (#7660) 
## Summary

Replaces the single-roundtrip `UNION ALL` DeltaChannel read with a
two-stage query that avoids fetching unused snapshot blobs, then removes
the old combined path entirely.

### Problem

`_get_channel_writes_history` used a single `UNION ALL` query that
fetched **all** checkpoint metadata, writes, and blobs for a
`(thread_id, channel)` in one shot. With `snapshot_frequency=N`, this
pulled back O(N/freq) full-size snapshot blobs even though only the
nearest one is needed to seed reconstruction. At 500 turns with
`snapshot_frequency=10`, this meant fetching ~100 complete
message-history snapshots per read.

### Solution

Two-stage read:
- **Stage 1** — lightweight scan of `checkpoints` only (no blob bytes):
walks the parent chain from the target checkpoint and stops at the first
ancestor with a snapshot, returning `chain_cids` and `seed_version`
- **Stage 2** — targeted fetch: only the writes for `chain_cids` and the
single seed blob at `seed_version`

The two-stage path is now unconditional — the old combined query and
`LG_DELTA_TWO_STAGE_QUERY` env-var gate have been removed.

### Sentinel cleanup

`DELTA_SENTINEL` is now a pure in-memory signal and is never written to
storage:
- Postgres `put()` already stripped it from `channel_values` before
writing blobs
- Memory saver `put()` now stores `"empty"` instead of serializing the
sentinel
- `EXT_DELTA_SENTINEL` (msgpack ext code 8) removed from
`JsonPlusSerializer`
- `DELTA_SENTINEL` is kept as an in-memory marker:
`DeltaChannel.checkpoint()` returns it so savers know to skip it, and
`_ChannelWritesHistory.seed` uses it to mean "no snapshot found, start
from empty"

## Performance

Benchmarked at `snapshot_frequency=10` on Postgres (`~100 tok/msg`):

| turns | old combined query | two-stage |
|------:|-------------------:|----------:|
| 50    | 6.0ms              | 2.8ms  (2.1x faster) |
| 100   | 10.1ms             | 5.6ms  (1.8x faster) |
| 500   | **216.1ms**        | 15.3ms (**14x faster**) |

The old query's read time grew super-linearly with turn count because
each read fetched O(N/freq) full snapshot blobs. Two-stage keeps read
depth bounded by `snapshot_frequency` regardless of thread length.

## Test plan

- `make test` in `libs/checkpoint`, `libs/checkpoint-postgres`,
`libs/langgraph`
- Removed `test_delta_sentinel_serde_round_trip` (sentinel no longer
serializable)
- Updated `test_memory.py` — delta channel blobs stored as `"empty"`,
not serialized sentinel
- Updated `test_channels.py` — `channel_values` no longer contains
sentinel key for DeltaChannels
- Deleted `test_delta_channel_two_stage_benchmark.py` (one-stage vs
two-stage comparison; path no longer exists)

Quanzheng LongandGitHub c8c58a0768 fix(langgraph): make NodeTimeoutError retryable by default (#7659) 
## Summary

`NodeTimeoutError` previously inherited from `TimeoutError`, which is a
subclass of `OSError`. Since `OSError` is in the default `RetryPolicy`
blocklist, timeout errors from `TimeoutPolicy` were silently **not
retried** unless the user explicitly set `retry_on=NodeTimeoutError`.

This PR changes `NodeTimeoutError` to inherit from `Exception` directly,
so that the default `RetryPolicy` treats it as retryable — matching user
expectations when both `RetryPolicy` and `TimeoutPolicy` are configured
together.

- Change `NodeTimeoutError(TimeoutError)` →
`NodeTimeoutError(Exception)`
- Add test asserting `NodeTimeoutError` is retryable with the default
policy
- Add observer-ordering tests pinning down `finish=error` emission
timing relative to retry backoff, error handler start, and retry
exhaustion

## Breaking change

Code that catches `NodeTimeoutError` via `except TimeoutError` or
`except OSError` will no longer match. Use `except NodeTimeoutError`
instead.

## Test plan

- [x] `test_should_retry_default_retry_on` — asserts `NodeTimeoutError`
is retryable with default `RetryPolicy()`
- [x] Existing timeout+retry tests continue to pass (`test_retry.py`)

 		40ab009c62 feat: allow graph to graceful shutdown/drain by request (#7274) 
## Summary

Adds cooperative drain support for Pregel runs so a graph can be asked
to stop at the next superstep boundary, persist its checkpoint, and
surface a resumable terminal exception.

- New `RunControl` (in `langgraph.runtime`) — a thread-safe handle whose
`request_drain(reason="shutdown")` sets a single flag.
- New `GraphDrained(GraphBubbleUp)` exception (in `langgraph.errors`)
raised when a run exits early due to drain. Carries the `reason` string.
- New `control: RunControl | None` kwarg on `invoke` / `ainvoke` /
`stream` / `astream` / `stream_v2` / `astream_v2`. Wired through to
`Runtime.control`, so nodes can read `runtime.control.drain_requested` /
`drain_reason` and even call `request_drain()` from inside a node.
- Stream transformers learn `"drained"` as a terminal `SubgraphStatus`.

The intended use is hooking SIGTERM (or any external supervisor signal)
to `control.request_drain("sigterm")` so an in-flight graph run can stop
cleanly and be resumed later from the saved checkpoint.

## Semantics: cooperative, between-superstep

`request_drain()` flips a flag. The Pregel loop checks it at the top of
each `tick()`, **after** the previous superstep's writes have been
applied and checkpointed. It never preempts work that is already
running.

| Scenario | Behavior |
|---|---|
| Node mid-execution (blocking I/O, sleeps, etc.) | Runs to completion.
Drain takes effect on the next superstep. |
| Node with a retry policy currently retrying | Retry loop runs to
exhaustion or success (drain is not checked between retries). Drain
takes effect on the next superstep. |
| Functional API: `@entrypoint` with pending `@task` futures |
Entrypoint and all dispatched tasks complete; drain takes effect after
the entrypoint returns. |
| Graph naturally finishes on the same tick where drain was requested
(no more tasks) | Treated as `done`; returns normally. **No
`GraphDrained` is raised.** The caller can inspect
`control.drain_requested` afterwards to distinguish a
drained-but-completed run from a normal one. |
| More tasks remain | Raises `GraphDrained(reason)`. The checkpoint of
the last completed superstep is saved (also under `durability="exit"`).
Resume with `invoke(None, config)` / `ainvoke(None, config)`. |
| Subgraph requests drain | `GraphDrained` bubbles up through the parent
loop and stops it at its own next superstep boundary; the parent's
checkpoint is saved and resumable. |

Drain does **not** cancel asyncio tasks or kill threads. Pair it with a
graceful timeout + `task.cancel()` (or process exit) if you need a hard
upper bound — see `test_drain_then_cancel_after_graceful_timeout` for
the recommended pattern.

## Usage

```python
from langgraph.runtime import RunControl
from langgraph.errors import GraphDrained

control = RunControl()

# In a signal handler, supervisor, etc.:
# control.request_drain("sigterm")

try:
    result = graph.invoke(input, config, control=control)
    if control.drain_requested:
        # finished naturally on the same tick where drain was requested
        ...
except GraphDrained as e:
    # checkpoint saved; resume later with the same config
    log.info("graph drained: %s", e.reason)
```

## Test plan

- [x] Sync + async drain stops the next superstep
(`test_run_control_request_drain_stops_future_steps[_async]`)
- [x] Drain on the terminal step finishes normally
(`test_drain_requested_in_terminal_step_finishes_normally[_async]`)
- [x] `durability=\"exit\"` persists a resumable checkpoint on drain
(`test_drain_with_exit_durability_persists_resume_checkpoint`)
- [x] Subgraph drain bubbles up and parent resumes correctly
(`test_drain_from_subgraph_can_resume_parent`)
- [x] External thread / task triggering drain mid-run
(`test_external_drain_concurrent_sync` / `_async`)
- [x] Drain + hard cancel after graceful timeout
(`test_drain_then_cancel_after_graceful_timeout`)
- [x] Functional API: in-flight `@task` futures still resolve after
`request_drain()`
(`test_request_drain_allows_inflight_[a]call_scheduling`)
- [x] `control` kwarg wired through `stream_v2`
(`test_stream_v2_accepts_control_for_drain`)
- [x] `Runtime.merge` preserves `control`
(`test_merge_runtime_preserves_run_control`)

1.2.0a1 checkpoint==4.1.0a1 		2026-04-29 15:23:31 -07:00
Sydney RunkleandGitHub f95d2309f9 release(checkpoint-postgres): pin to checkpoint 4.1.0a1 (#7648) 
## Summary
- Bumps `langgraph-checkpoint-postgres`'s pin on `langgraph-checkpoint`
from `>=4.0.3,<5.0.0` to `>=4.1.0a1,<5.0.0` so the postgres alpha
(3.1.0a1) requires the matching checkpoint alpha released in #7647.
- Mirrors the same pin update applied to `langgraph` (1.2.0a1) on
`wfh/releases/timers`.

## Why
The three alphas (checkpoint 4.1.0a1, checkpoint-postgres 3.1.0a1,
langgraph 1.2.0a1) are meant to be tested as a coherent set. `langgraph`
already pins `>=4.1.0a1`; checkpoint-postgres was missed in that release
and is still letting resolvers fall back to 4.0.x.

## Test plan
- [ ] CI green
- [ ] `uv lock` resolves cleanly across libs (verified locally via `make
lock` — no lock file changes since editable paths already resolved to
4.1.0a1)

 		5c18bde0f8 feat(langgraph): DeltaChannel: store sentinel in blobs, reconstruct from checkpoint_writes (#7586) 
# DeltaChannel: sentinel-based checkpoint blobs + write-replay
reconstruction

## Summary

`DeltaChannel` is a new fold-reducer channel that stores only a
zero-byte sentinel in checkpoint blobs instead of the full accumulated
value. On restore, the runtime replays ancestor writes through the
reducer to reconstruct state. For long-running threads with large
accumulating state (e.g. message histories), this delivers dramatically
smaller checkpoint blobs with configurable read-depth bounds.

```python
from typing import Annotated
from typing_extensions import TypedDict
from langgraph.channels.delta import DeltaChannel
from langgraph.graph.message import _messages_delta_reducer

class State(TypedDict):
    # blob per step: ~60 bytes (sentinel) instead of growing full list
    messages: Annotated[list, DeltaChannel(_messages_delta_reducer)]
    # bound read depth to 10 steps via periodic snapshots
    messages_bounded: Annotated[list, DeltaChannel(_messages_delta_reducer, snapshot_frequency=10)]
```

**Takeaway:** `snapshot_frequency=10` matches full-list read latency
while still saving 5x on blob storage and ~4x on total storage.

## How it works

### Checkpoint blobs

`checkpoint()` always returns `DELTA_SENTINEL` (a zero-byte msgpack ext
marker) instead of the accumulated value. On restore, the saver's
`_get_channel_writes_history` walks the ancestor chain collecting
`checkpoint_writes` entries and replays them through the reducer:

```python
# blob stored per step: ~1 byte (sentinel)
# vs. full list growing O(N) every step with BinaryOperatorAggregate
```

### Reducer interface

`DeltaChannel` takes a **batch reducer** `(state, list[writes]) ->
state` — all writes for a step arrive in one call, enabling single-pass
implementations:

```python
# ❌ Don't use add_messages directly — it's a binary operator, not a batch reducer
messages: Annotated[list, DeltaChannel(add_messages)]  # wrong

# ✅ Use _messages_delta_reducer — single pass, dedup by ID, RemoveMessage support
messages: Annotated[list, DeltaChannel(_messages_delta_reducer)]

# ✅ Or write your own batch reducer for custom types
def my_dict_reducer(state: dict, writes: list[dict]) -> dict:
    result = dict(state)
    for w in writes:
        result.update(w)
    return result

files: Annotated[dict, DeltaChannel(my_dict_reducer)]
```

### Snapshot frequency

`snapshot_frequency=N` writes a full `_DeltaSnapshot` blob every N
pregel steps, bounding replay depth regardless of thread length.
Snapshots are eager — written even if the channel had no update that
step, so the depth bound always holds:

```python
# Replay walks at most 10 ancestors before hitting a snapshot
messages: Annotated[list, DeltaChannel(_messages_delta_reducer, snapshot_frequency=10)]
```

### Migration from `BinaryOperatorAggregate`

Pre-existing threads written under `BinaryOperatorAggregate` work
transparently after swapping the annotation — the saver detects a
plain-value ancestor blob and uses it as the reconstruction seed:

```python
# Before: BinaryOperatorAggregate stores full list every step
items: Annotated[list, add_messages]

# After: DeltaChannel — existing checkpoints still readable, new steps use sentinel
items: Annotated[list, DeltaChannel(_messages_delta_reducer)]
```

### Async write-ordering safety

In `durability="async"` mode (default), `put_writes` calls are
fire-and-forget. `AsyncPregelLoop` tracks in-flight `aput_writes`
futures for DeltaChannel channels in `_delta_write_futs` and drains them
via `await asyncio.gather()` in `_checkpointer_put_after_previous`
before `aput()` — ensuring `checkpoint_writes` are durable before the
sentinel blob is committed.

---

## What's in scope

- **`libs/langgraph/langgraph/channels/delta.py`** — `DeltaChannel`
implementation
- **`libs/langgraph/langgraph/graph/message.py`** —
`_messages_delta_reducer` (experimental)
- **`libs/checkpoint/`** — `_get_channel_writes_history` ancestor-walk
API on `BaseCheckpointSaver`, `InMemorySaver` optimized override
- **`libs/checkpoint-postgres/`** — `PostgresSaver` /
`AsyncPostgresSaver` single-roundtrip UNION ALL override
- **`libs/langgraph/langgraph/pregel/`** — `channels_from_checkpoint` /
`create_checkpoint` wiring, async write-ordering safety

---

## Follow-ups

- **Batch reconstruction**: each DeltaChannel field issues its own
`_get_channel_writes_history` call; a single walk collecting all
sentinel channels would reduce roundtrips proportionally to the number
of DeltaChannel fields.
- **Sync write ordering**: `BackgroundExecutor.__exit__` guarantees
completion before `invoke()` returns, but within a run there's no
explicit ordering between `put_writes` and `put`. Two-phase commit for
sync would close this gap.
- **`ShallowPostgresSaver` compatibility**: shallow savers keep only the
latest checkpoint and have no parent chain to walk; DeltaChannel is
currently incompatible and should raise or warn at compile time.
- Updating the writes table w/ delta epoch ids for more efficient reads
- follow up w/ LSD checkpointer implementations to support delta
channel! and update prune

 		800071d0d4 chore: idle timeout (#7631) 
## Summary

Adds per-node `timeout` support to async StateGraph/Pregel nodes and to
the functional API (`@task` / `@entrypoint`). A timeout caps how long a
single node attempt may run, either as a hard wall-clock budget
(`run_timeout`), or as an idle window that resets on observable progress
(`idle_timeout`), or both. When exceeded, LangGraph raises
`NodeTimeoutError`, clears writes from the failed attempt, and lets the
existing retry policy decide whether to retry.

## Public API

A single `timeout=` kwarg on `add_node`, `@task`, `@entrypoint`, and
`NodeBuilder.set_timeout`. Pass a number/`timedelta` for the simple case
(treated as a hard wall-clock cap), or a `TimeoutPolicy` (in
`langgraph.types`) for finer control:

```python
from datetime import timedelta
from langgraph.types import TimeoutPolicy

# simple: hard wall-clock cap on each attempt
builder.add_node("call_model", call_model, timeout=60)
builder.add_node("call_model", call_model, timeout=timedelta(minutes=2))

# full control
builder.add_node(
    "call_model",
    call_model,
    timeout=TimeoutPolicy(
        run_timeout=120,                # hard wall-clock cap in seconds, never refreshed
        idle_timeout=30,                # cap on time without observable progress, units in seconds
        refresh_on="auto",              # "auto" | "heartbeat"
    ),
)
```

- `run_timeout`: hard wall-clock cap on a single attempt; never
refreshed.
- `idle_timeout`: progress-resetting cap. Refreshed by writes, stream
output, yielded async stream chunks, child-task scheduling, runtime
stream-writer calls, and any LangChain callback event from descendants
of the node's run. `runtime.heartbeat()` is a manual signal for work
that doesn't naturally emit any of these.
- `refresh_on="heartbeat"` narrows the refresh source to explicit
`runtime.heartbeat()` only — useful when you want a strict idle
definition that isn't reset by chatty subordinates.

For long-running async work that doesn't naturally emit progress:

```python
async def call_model(state: State, runtime: Runtime) -> State:
    while still_working:
        ...
        runtime.heartbeat()
    return {"messages": [response]}
```

`NodeTimeoutError` subclasses `TimeoutError` and carries `node`,
`timeout`, `run_timeout`, `idle_timeout`, `elapsed`, and `kind` (`"run"`
or `"idle"`). If the node's `retry_policy` permits `TimeoutError` it'll
retry; the timer resets per attempt.

## Why async-only

Sync Python code cannot be safely cancelled in-process, so timeouts only
apply to async nodes/tasks. Sync nodes with a `timeout` are rejected at
compile time (covers direct nodes, wrapped runnables, sequences, and
`RunnableParallel` branches); `run_with_retry` rejects them at runtime
as a safety net.

## What gets cancelled and what doesn't

When a watchdog fires:

1. The attempt scope is closed under a lock so any in-flight
`CONFIG_KEY_SEND` / stream / child-task scheduling that races with the
timeout is dropped atomically.
2. Buffered `task.writes` are cleared so pre-timeout writes from the
failed attempt don't leak into the checkpoint after a retry succeeds.
3. The background `asyncio.Task` is cancelled; its eventual exception is
drained via a done-callback so asyncio doesn't log it.

Only the watchdog's own `TimeoutError` converts to `NodeTimeoutError`,
so user-raised `asyncio.TimeoutError`, built-in `TimeoutError`, and
`NodeTimeoutError` from a child node continue to propagate unchanged.

Child tasks already scheduled before the timeout fired still complete —
they aren't part of the cancelled task's structured cancellation
surface. This is intentional and tested.

## External-watchdog hook

WARNING: THIS API IS IN ALPHA AND SUBJECT TO CHANGE.

`CONFIG_KEY_TIMED_ATTEMPT_OBSERVER` is a per-config callback that
receives lifecycle events for each timed attempt:

- `start` — fired before the proc runs, with `task_id`, `task_name`,
`attempt`, `run_id`, `thread_id`, `checkpoint_ns`, `started_at`, and the
configured `run_timeout_secs` / `idle_timeout_secs` / `refresh_on`.
- `progress` — fired on each progress signal that resets the idle clock,
rate-limited to ~4 events per `idle_timeout` window so token-rate
callbacks don't flood the observer. Carries the same context plus
`progress_at`.
- `finish` — fired with `finished_at`, `status` (`"success"`/`"error"`),
`error_type`, `error_message`. `ParentCommand` and `GraphBubbleUp` are
treated as control flow, not errors.

This lets an orchestrating process listen to `start` + rolling
`progress` to compute its own kill deadline (`progress_at +
idle_timeout_secs`) and hard-kill a worker process if the in-process
cancellation deadlocks. Observer callbacks run in whatever thread fires
them, and any exception they raise is logged and swallowed.

## Implementation Notes

`runtime.heartbeat()` updates the progress timestamp without taking the
guarded write lock. This avoids lock overhead on high-frequency
callback/token paths and accepts a small timestamp race window, which is
negligible for expected coarse idle-timeout configurations.

## Testing

Covers timeout retry behavior, user-raised timeout propagation,
stale-write suppression, stream / callback / heartbeat progress resets,
sync-node rejection, `RunnableParallel` branch validation,
`StateGraph.add_node` behavior, lower-level Pregel behavior, observer
start/progress/finish events, and functional API compatibility.

I am going to implement this as an `idle_timeout` instead. I think
that's a better default behavior.

 		f4aee546ad fix(prebuilt): hydrate ToolNode state from channels via pregel helpers (#7594) 
## Summary

When `ToolNode` receives a bare `[tool_call]` list via the Send API (the
dispatch shape `create_agent` will use once langchain-ai/langchain#36960
lands), hydrate `ToolRuntime.state` from the current channel values
instead of requiring the dispatcher to inline the full agent state dict
into every `Send.arg`.

Motivation: the paired langchain PR drops the `ToolCallWithContext`
wrapper from `create_agent`'s tool dispatch, which eliminates an O(N²)
storage term on `__pregel_tasks` checkpoint writes. Without this
companion change there would be no path for the tool node to see the
graph state.

## What changed

- `libs/prebuilt/langgraph/prebuilt/tool_node.py` — `_extract_state`
grows a third branch for list-form input. When the input is a list whose
last entry is a `ToolCall` dict, read the current channel values via
`CONFIG_KEY_READ` and return them as the state dict.

The full new logic is four lines inline in `_extract_state`:

```python
read = config.get(CONF, {}).get(CONFIG_KEY_READ)
if read is None:
    return {}
# Pregel installs CONFIG_KEY_READ as
# `functools.partial(local_read, scratchpad, channels, managed, task)`.
channels = read.args[1]
return cast("dict[str, Any]", read(list(channels), False))
```

- No changes to the pregel read machinery (`local_read`, `ChannelRead`).
- Only channel values are read; managed values have their own injection
path (`ToolRuntime.context`, `InjectedContext`) and were never in the
pre-fix inlined state dict, so we don't add them here.
- Falls back to `{}` when invoked outside a Pregel context (e.g. direct
`ToolNode(...).invoke([tool_call])` from a test harness), which
preserves existing `ToolNode` direct-invocation test behavior.

- `libs/prebuilt/tests/test_on_tool_call.py` — two new tests covering
the list-form hydration path (sync + async). They build a
`functools.partial` that matches Pregel's real `CONFIG_KEY_READ` shape
and assert `ToolRuntime.state` reflects the current channel values.

## Why it's safe

- **Same snapshot semantics as before.** `Send` is emitted at
end-of-super-step-N; consumed at start-of-super-step-N+1. Channels at
that point reflect every write from super-step N (including the new
AIMessage the tool calls originated from). Parallel tool tasks in the
tools super-step all read the same values since sibling writes don't
land until end-of-super-step.
- **Legacy `ToolCallWithContext` path preserved.** External dispatchers
that still inline state continue to work unchanged — `_extract_state`
checks that branch first.

## Test plan

- [x] `make test` in `libs/prebuilt` — **204 pass**
- [x] Two new hydration tests (sync + async) green
- [x] `make format` / `make lint` / `mypy` clean

 		85cd64ed69 fix(checkpoint): revive lc=2 JSON blobs for safe types without allowlist (#7582) 
## Summary

Fixes #7498 — `MESSAGE_COERCION_FAILURE` when resuming threads
checkpointed before v1.0.1.

**Root cause:** PR #6269 (v1.0.1) added an `_allowed_json_modules`
security gate to `JsonPlusSerializer._reviver`. The gate defaults to
`None`, so old `"json"`-format checkpoint blobs containing `lc=2`
constructor dicts (the pre-msgpack serialization format for pydantic
objects like `HumanMessage`) are now returned as raw dicts instead of
being reconstructed. Those raw dicts reach `add_messages →
convert_to_messages`, which sees `type="constructor"` and raises
`MESSAGE_COERCION_FAILURE`. Fresh first-turn messages are unaffected
because current `dumps_typed` only writes `"msgpack"` blobs.

**Fix:** `_reviver` now reconstructs `lc=2` blobs whose target class is
already in `SAFE_MSGPACK_TYPES` — the same curated allowlist already
used by the msgpack deserialization path (includes all standard
LangChain message types). Unknown classes are still blocked, preserving
the security intent of #6269.

## Changes

- `libs/checkpoint/langgraph/checkpoint/serde/jsonplus.py` — add
`_is_safe_json_type()` helper; update `_reviver` and
`_check_allowed_json_modules` to allow safe types without an explicit
allowlist
- `libs/checkpoint/tests/test_jsonplus.py` — two new regression tests:
safe-type `lc=2` blobs revive correctly; unknown-type `lc=2` blobs stay
blocked

## Test plan

- [ ] `test_lc2_json_safe_type_revives_without_allowlist` —
`HumanMessage`/`AIMessage` lc=2 JSON blobs round-trip to proper
`BaseMessage` objects with no allowlist configured
- [ ] `test_lc2_json_unknown_type_stays_blocked_without_allowlist` —
`pprint.pprint` lc=2 blob still returns raw dict (not reconstructed)
- [ ] `test_deserde_invalid_module` — existing behaviour unchanged
- [ ] Full `test_jsonplus.py` suite: 93/93 passing

 		aeff9549c2 chore: node-level timeouts (#7599) 
This PR implements task/node-level timeouts. 

Since python has a terrible multi-processing model, we make two
concessions:
- we only support for async functions/nodes. Sync nodes with a timeout
raise an error at compile time
- we implement this with asyncio wait_for in the async path.
 
Each timed attempt is wrapped in _retry.py, and the timer is reset on
each node-level retry. When the deadline is exceeded LangGraph raises
NodeTimeoutError, clears buffered writes, and prevents any late writes
or child-task scheduling from leaking past the timeout via
_TimedAttemptScope.

The design also adds a timed-attempt observer hook
(CONFIG_KEY_TIMED_ATTEMPT_OBSERVER) that emits start/finish events with
identifiers and deadlines. This means that if you have an orchestrating
process starting a worker process, it can listen to start/end events and
hard-kill the process to enforce a timeout if there is a deadlock.

ccurmeandGitHub 1a248cba45 release(prebuilt): 1.0.11 (#7610) prebuilt==1.0.11 2026-04-24 14:16:17 -04:00
Hunter LovellGitHubSydney Runkle
 		45246f6c74 feat(prebuilt): allow ToolNode tools to return list[Command | ToolMessage] (#7596) 
## Summary

Extends `ToolNode` so that a single tool invocation can return
`list[Command | ToolMessage]` instead of only a single `Command` or
`ToolMessage`. This brings `ToolNode`'s per-tool-call contract in line
with the rest of LangGraph, where nodes can already return multiple
Commands.

Depends on langchain-ai/langchain#36963 which allows
`list[ToolOutputMixin]` to pass through `BaseTool._format_output`
unchanged.

## Changes

### `libs/prebuilt/langgraph/prebuilt/tool_node.py`

**New list-return gate in `_execute_tool_sync` / `_execute_tool_async`**
— After the existing `Command` and `ToolMessage` checks, a new branch
accepts `list[Command | ToolMessage]` and routes it through
`_validate_tool_command_list`. Lists with non-`Command`/`ToolMessage`
elements raise `TypeError`. Both sync and async paths are updated
symmetrically.

**`_validate_tool_command_list`** — Enforces the terminating-ToolMessage
rule: exactly one `ToolMessage` in the list must carry `tool_call_id ==
<outer_id>` (top-level or nested inside a `Command.update["messages"]`).
Zero or multiple terminators raise `_MissingToolMessageError`.
Individual Commands in the list are validated via the existing
`_validate_tool_command`; when a Command lacks the terminator (which is
allowed since the list-level check handles it), the
`_MissingToolMessageError` is caught and the already-normalized command
from the exception is used.

**`_MissingToolMessageError`** — A `ValueError` subclass raised by
`_validate_tool_command` (and `_validate_tool_command_list`) when no
matching `ToolMessage` is found. Carries the already-normalized command
so callers can recover without re-doing deepcopy/message-conversion
work. Using a typed exception avoids brittle string-matching on error
messages.

**`_combine_tool_outputs`** — Flattens list entries at the top of the
method so downstream combiner logic (parent-`goto` accumulation,
ToolMessage wrapping) is unchanged.

**Response processing moved inside try/except** — In both sync and async
execute methods, the response validation (Command/ToolMessage/list
checks) now runs inside the existing error-handling try block, so
validation errors from the list path go through `_handle_tool_errors`
like other tool errors.

**Return type signatures** widened on `_execute_tool_sync`,
`_execute_tool_async`, `_run_one`, `_arun_one` to include `list[Command
| ToolMessage]`.

### `libs/prebuilt/tests/test_tool_node.py`

New tests covering: valid list returns (top-level terminator, nested
terminator, parent-goto + terminator), regression tests for single
Command/ToolMessage returns, invalid cases (no terminator, multiple
terminators), async parity, integration with mixed list/non-list tool
calls, and `_handle_tool_errors` interaction.

 		0a26b471d3 fix(langgraph): don't propagate ReplayState to subgraphs on plain resume (#7561) 
**Description:**
When clients resume an interrupted subgraph with `Command(resume=...)`
plus an explicit `checkpoint_id` in the config (the pattern LangGraph
Studio and the API server emit on every resume), the subgraph restarts
from its first node instead of continuing at the interrupted node.

Fix: gate `ReplayState` propagation on `is_time_traveling` rather than
`is_replaying`, so a resume that happens to carry a head checkpoint_id
behaves the same as one with just a thread_id.

**Verification:** added regression test
`test_subgraph_interrupt_resume_with_explicit_head_checkpoint_id` (fails
on main, passes with fix, across memory/sqlite/sqlite_aes).
Full `test_time_travel.py`, `test_time_travel_async.py`,
`test_interruption.py`, and all pregel subgraph/interrupt/resume/replay
tests still pass.

 		aa94790f36 fix(langgraph): remove strict add_handler type check that breaks OTel instrumentation (#7544) 
## Summary

Removes the `add_handler()` overrides on `_GraphCallbackManager` and
`_AsyncGraphCallbackManager` that reject handlers not inheriting from
`GraphCallbackHandler`. This fixes a regression in 1.1.7 where
`opentelemetry-instrumentation-langchain` (and likely other libraries
that patch `BaseCallbackManager.__init__`) crash with `TypeError:
handlers must inherit GraphCallbackHandler` at invocation time.

## Why this is safe

The strict type check is redundant — `_configure_graph_callbacks` and
`_filter_graph_handlers` already filter handlers to
`GraphCallbackHandler` instances at construction time. Non-graph
handlers that enter via external patches (like OTel's monkey-patch) are
harmless because `handle_event("on_interrupt", ...)` /
`handle_event("on_resume", ...)` will simply no-op on handlers that
don't implement those methods.

## What changed

- Deleted `add_handler()` override from `_GraphCallbackManager` (was
lines 248-255)
- Deleted `add_handler()` override from `_AsyncGraphCallbackManager`
(was lines 324-331)
- No other changes — 18 lines removed, 0 added

## Test plan

- [x] All 8 existing `test_graph_callbacks.py` tests pass (`make test
TEST=tests/test_graph_callbacks.py`)
- [x] `make lint` passes
- [x] `make format` passes (no changes needed)
- [x] Verified fix locally: `LangchainInstrumentor().instrument()` +
`create_react_agent()` + `graph.ainvoke()` no longer raises `TypeError`
- [x] Verified the graph lifecycle callbacks (`on_interrupt`,
`on_resume`) still work correctly

Closes #7543

Sydney RunkleandGitHub 51cbdbd5cd fix: time travel when going back to interrupt node (#7498) 
# Fix: Create fork checkpoint on subgraph time travel

## Problem

When time-traveling to a subgraph checkpoint that has an interrupt, and
then resuming, the resume would load the **wrong state** — it would pick
up the original execution's latest checkpoint instead of the
time-traveled one.

This happened because replaying from a subgraph checkpoint never created
a new parent checkpoint. If the replay hit an interrupt before
`after_tick()` ran, no checkpoint was written at all, so the parent's
"latest" checkpoint was still the old one from the original execution.

## Fix

When the loop detects a time-travel replay (not an `update_state` fork),
it now **eagerly writes a fork checkpoint** at the start of the tick.
This ensures:

1. The parent thread's latest checkpoint points to the replayed state
2. Subsequent `Command(resume=...)` calls find the correct checkpoint
3. Stale `INTERRUPT` pending writes from the old checkpoint are cleared
(they reference old task IDs)

Additionally, the subgraph replay logic now uses the **parent checkpoint
ID** (from `prev_checkpoint_config`) when resolving subgraph checkpoints
during time-travel, matching the existing behavior for `update_state`
forks.

## Checkpoint flow diagrams

### Before fix: time travel leaves no fork

```
Original execution:

  C0 (start) --> C1 (step_a) --> C2 (ask_1 interrupt) --> C3 (resume) --> C4 (ask_2 interrupt) --> C5 (done)

Time travel to C2 (subgraph config):

  Replay runs... hits interrupt... no new checkpoint written.
  Parent "latest" is still C5.

  Command(resume="new_answer"):
    Loads C5 (wrong!) instead of the replayed C2 state.
```

### After fix: time travel creates a fork

```
Original execution:

  C0 --> C1 --> C2 --> C3 --> C4 --> C5 (done)

Time travel to C2 (subgraph config):

  C0 --> C1 --> C2 --> C3 --> C4 --> C5
                  \
                   F1 (fork, source="fork")  <-- new latest

  Command(resume="new_answer"):
    Loads F1 (correct!) --> resumes from the right state.

  After full resume:

  C0 --> C1 --> C2 --> C3 --> C4 --> C5
                  \
                   F1 --> F2 (ask_1 result) --> F3 (ask_2 interrupt) --> F4 (done)
```

### Manual fork via `update_state` (unchanged)

```
  C0 --> C1 --> C2 --> C3
                  \
                   U1 (source="update")  <-- created by update_state()

  This path already worked. The fix skips update/fork sources
  so existing behavior is preserved.
```

## Changes

- **`libs/langgraph/langgraph/pregel/_loop.py`**:
- Extract `is_time_traveling` flag from the existing replay detection
logic for reuse
- Write a fork checkpoint (`source="fork"`) eagerly at the start of a
time-travel tick, before execution begins
- Clear stale `INTERRUPT` pending writes when creating the fork (they
reference old task IDs that won't match the new checkpoint)
- Unify subgraph replay ID resolution: check `source in ("update",
"fork")` instead of a separate `is_time_traveling` condition, since the
new fork checkpoint now has `source="fork"`
- **`libs/langgraph/tests/test_time_travel.py`** and
**`test_time_travel_async.py`**: Added 4 new test cases (sync + async):
- `test_replay_from_before_interrupt_then_resume` — replays from a
checkpoint before an interrupt, resumes with a new answer, and verifies
the full checkpoint history (source, next, values) at each stage
- `test_subgraph_time_travel_resume_from_first_interrupt` — time-travels
to a subgraph's first interrupt, resumes both interrupts with new
answers, and verifies the fork creates a new branch while preserving the
original
- `test_subgraph_time_travel_resume_from_second_interrupt` —
time-travels to a subgraph's second interrupt, resumes with a new
answer, and verifies the first interrupt's original answer is preserved
- `test_subgraph_time_travel_checkpoint_pattern` — verifies the fork
checkpoint branches from the correct replay point and that the full
checkpoint tree is correct after resume
- **`libs/langgraph/tests/test_pregel.py`** /
**`test_pregel_async.py`**: Updated existing
`test_weather_subgraph_state` to account for the new fork checkpoint
appearing in history (history length increases by 1)
