Inline comments:
In `@core/data_manager/strategy/sqlite_strategy_impl.py`:
- Around line 730-731: Update the query construction in the lookback polling
flow so the fresh-row query filtered by id__gt=after_id always applies limit,
while fetching the bounded lookback range separately when lookback is positive.
Preserve the existing unlimited lookback<=0 behavior only where appropriate and
avoid loading the entire backlog into memory.
In `@env/patcheval/openhands_runner.py`:
- Around line 297-305: Replace the blocking stdout.readline loops in
_run_openhands (env/patcheval/openhands_runner.py:297-305) and _run_streamed
(env/patcheval/openhands_runner.py:428-436) with one shared deadline-aware
reader helper, using a reader thread with bounded queue.get or selectors with a
poll interval. Ensure silent child processes are checked against deadline,
killed when timed out, and reported with timed_out, while preserving normal EOF
and output handling at both call sites.
In `@env/patcheval/push_patcheval_images.sh`:
- Line 170: Ensure the success path in the failure-summary logic does not return
a non-zero status when FAIL_FILE is absent. Update the conditional around
FAIL_FILE before the summary so a missing file is treated as zero failures and
the script continues to the existing summary and successful exit.
In `@gateway/admission_control.py`:
- Line 78: Update the max_steps check in the admission-control flow to use the
session-wide binding.llm_step_count instead of
step_count_for(ctx.requested_model), preserving the existing nonnegative-limit
guard and rejection behavior.
- Line 70: Update the admission flow around route_sem.acquire and the
max_inflight_requests check so queued requests are bounded: reserve an admission
slot before waiting for the route semaphore, or enforce an equivalent per-route
queue-size limit with a timeout. Ensure saturated routes cannot retain unbounded
gateway tasks while preserving the existing inflight limit behavior.
- Line 72: Move the cleanup/exception-handling boundary in the route acquisition
flow before async with self._lock so cancellation while waiting for the lock
still invokes release(). Preserve the existing _route_acquired tracking and
release behavior for successful acquisitions, updating the relevant method
containing this lock block.
In `@gateway/app.py`:
- Around line 55-59: Update _ensure_default_max_tokens to be endpoint-aware: for
Responses requests, preserve an existing max_output_tokens value and inject the
configured default using max_output_tokens without adding max_tokens; retain the
current max_tokens behavior for chat and Anthropic requests.
In `@manager/simulation_worker.py`:
- Line 197: Update the task orchestration around _active_snapshot_loop so the
snapshot task is excluded from asyncio.gather(*tasks) with worker tasks; after
workers settle, cancel the snapshot task and await it in a finally block,
allowing cancellation to complete without preventing SimulationRunSummary from
returning.
In `@rl/buffer_server.py`:
- Around line 261-262: Update CloudStrategy.fetch_done_steps_with_context to
return a distinct row identity for each fetched record while separately
returning the next-page cursor used for last_served_id. Ensure the buffer
server’s served_pks check deduplicates by that row identity, so all rows in a
page are processed and pagination still advances with the cursor.
In `@rl/examples/patcheval/env.rjob.sh`:
- Line 48: Remove the plaintext remote DOCKER_HOST fallback in
rl/examples/patcheval/env.sh:31 and ensure the Docker-mode startup path in
run_eval_one.sh rejects insecure tcp:// endpoints unless authenticated TLS,
ssh://, or a Unix socket is configured. rl/examples/patcheval/env.rjob.sh:48
requires no direct change because it uses the separate RJob backend.
In `@rl/examples/patcheval/patcheval_eval_gateway.yaml`:
- Line 11: Revoke and rotate the exposed gateway credential, remove
rl/examples/patcheval/patcheval_eval_gateway.yaml (line 11) from version control
and purge it from repository history, then add that path to
rl/examples/patcheval/.gitignore. Update
rl/examples/patcheval/start_eval_gateway.sh (line 13) so it writes credentials
to an ignored or externally configured path instead of the tracked file.
Apply the same fix in `@rl/examples/patcheval/start_eval_gateway.sh` at line 13:
The launcher selects the tracked secret-bearing configuration path by default.
In `@rl/patches/gdn_packed_seq.py`:
- Around line 58-60: Update the packed sequence handling around
packed_seq_params so that for qkv_format "thd", resolve cu_seqlens_q_padded
using cu_seqlens_q and seq_len before passing offsets to convolution or
recurrence paths, then validate that the final resolved offset equals seq_len
and reject mismatches.
- Around line 85-86: Update the packed-sequence path in the module containing
the causal convolution and torch_chunk_gated_delta_rule dispatch to reject
cu_seqlens_q when deterministic_mode is enabled, matching NVIDIA’s
unsupported-combination behavior; alternatively, provide boundary-aware
convolution and recurrence fallbacks that pass sequence boundaries through both
operations. Preserve existing behavior for unpacked inputs and non-deterministic
packed dispatch.
In `@rl/patches/sitecustomize.py`:
- Around line 14-18: Update the gdn_packed_seq import handling in
sitecustomize.py to fail fast when the required monkey-patch cannot load:
re-raise the caught import exception or disable the default thd path before job
startup, rather than continuing after printing a warning. Ensure Megatron’s
unpatched GatedDeltaNet.forward cannot receive packed_seq_params.
In `@rl/restart_pool_test.sh`:
- Line 32: Update both log redirections in rl/restart_pool_test.sh at lines
32-32 and 37-37 to use securely created mktemp files instead of predictable /tmp
paths, and validate that POOL is a positive integer before using it in any
filename.

Keep the fresh-row query bounded.
With lookback > 0, this removes the only query limit. id__gt=cursor_floor includes the lookback range and all newer terminal rows. A large backlog can therefore load every matching row into memory in one poll.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
One blocking-read pattern defeats both timeouts. Both loops check the deadline only when readline() returns "", which happens at EOF. While a child process stays alive and writes nothing, the loop blocks inside readline(), the deadline test is unreachable, and proc.kill() never runs. Replace the read with a deadline-aware mechanism (reader thread plus bounded queue.get, or selectors with a poll interval) in one shared helper used by both call sites.

The script exits 1 on the success path.
FAIL_FILE is removed at line 159 and recreated only by a failing worker. When every push succeeds, [[ -f "${FAIL_FILE}" ]] returns 1. It is the last command of the else branch, so the if compound returns 1, and set -eo at line 30 terminates the script before the summary at lines 173-181. Operators then see a non-zero exit and no summary after a fully successful run, and any wrapping automation treats the run as failed.

Bound queued route requests.
Line 70 waits before the max_inflight_requests check. Requests queued on a saturated route do not count toward that limit. No timeout or queue-size limit applies to these waiters. A slow upstream can retain unbounded gateway tasks and exhaust capacity.
Reserve a bounded admission slot before waiting, or implement a per-route queue limit with a timeout.

Release the route slot if cancellation occurs before _lock is acquired.
release() releases the semaphore only after _route_acquired is recorded. Cancellation while waiting for _lock occurs before that record and bypasses the inner try, so repeated cancellations can permanently reduce route capacity. Move the cleanup boundary before async with self._lock.

Remove the committed gateway API key and stop writing secrets to tracked paths.
The launcher writes PATCH_EVAL_API_KEY into this tracked configuration file, which is then loaded into gateway route state and used for outbound authorization. Revoke and rotate the exposed key, purge it from repository history, remove the secret-bearing file from version control, and generate configuration only in an ignored or temporary path.

Resolve and validate THD sequence offsets.
When packed_seq_params.qkv_format == "thd", resolve cu_seqlens_q_padded against cu_seqlens_q and seq_len before passing the offsets to the convolution and recurrence paths. Reject offsets whose final value differs from seq_len; otherwise alignment padding can leave seq_idx and recurrence boundaries inconsistent with the processed tensor.

🌐 Web query:
Find the version-applicable source and API contracts for NVIDIA Megatron-LM megatron/core/ssm/gated_delta_net/gdn.py, especially GatedDeltaNet.forward, deterministic mode, cu_seqlens, and causal_conv1d_fn/seq_idx; also find the FLA implementations of chunk_gated_delta_ruleandtorch_chunk_gated_delta_rule, including whether the latter accepts cu_seqlens and how variable-length boundaries are handled.
💡 Result:
In NVIDIA Megatron-LM, the GatedDeltaNet module is defined in megatron/core/ssm/gated_delta_net/gdn.py (or via the facade in megatron/core/ssm/gated_delta_net.py) [1][2][3]. GatedDeltaNet.forward API and Deterministic Mode: The forward pass accepts hidden_states, attention_mask, inference_context, and packed_seq_params [2][4]. When packed_seq_params is provided, it resolves cu_seqlens for query and KV states [1]. A critical restriction is that packed sequences currently do not support deterministic_mode, as noted by the assertion assert not self.config.deterministic_mode [1][3]. The module provides torch_chunk_gated_delta_rule as a Torch-native, deterministic fallback implementation because the underlying Flash Linear Attention (FLA) implementation is not deterministic [4][5]. Causal Conv1D and seq_idx: Megatron Core distinguishes between causal_conv1d_fn and causal_conv1d_varlen_fn [6][7]. While causal_conv1d_fn is typically used for static batching and requires seq_idx to handle sequence boundaries [8], it is noted that this kernel can have API ambiguities (e.g., positional argument collisions between activation and seq_idx depending on the specific kernel version used) [9]. For packed variable-length sequences, Megatron utilizes causal_conv1d_varlen_fn, which accepts cu_seqlens directly [6]. FLA Implementations (chunk_gated_delta_rule / torch_chunk_gated_delta_rule): 1. chunk_gated_delta_rule: This refers to the FLA-native implementation, which manages variable-length state internally [10]. 2. torch_chunk_gated_delta_rule: This is the Megatron-native deterministic fallback [4][5]. It does not natively accept cu_seqlens in its basic signature; instead, the deterministic path is specifically designed to bypass the complex variable-length packing support that requires cu_seqlens, reinforcing the module's enforcement that deterministic mode and packed sequences (THD format) are mutually exclusive [1][3]. Variable-length handling: Variable-length boundaries are managed via packed_seq_params (THD format) in the main path, which uses cu_seqlens to resolve sequences [1][10]. For kernels supporting variable lengths, like causal_conv1d_varlen_fn, boundary handling is performed via either precomputed metadata (seq_idx/seq_start) or computed dynamically from cu_seqlens [6][7].

Reject packed deterministic dispatch or add boundary-aware fallbacks.
When cu_seqlens_q is set, self.conv1d(qkv) at lines 85-86 has no boundary metadata and can convolve across trajectories. The deterministic branch at lines 136-143 calls torch_chunk_gated_delta_rule without cu_seqlens; its recurrence carries state across the concatenated sequence. NVIDIA rejects packed sequences with deterministic_mode. Add an early guard or implement per-sequence fallbacks.

Do not default NCCL_SOCKET_IFNAME to bond0 without validation.
This default is also propagated to the training job. On nodes without an interface matching the bond0 prefix, forcing Socket transport can prevent NCCL from initializing. Leave the setting unset by default, derive it during preflight, or require an explicit value for deployments that guarantee this interface.

Traverse all descendant processes before killing the launcher.
This code finds only children and grandchildren. For launcher -> child -> grandchild -> great-grandchild, the great-grandchild is absent from all_pids. Killing its ancestors can orphan it, so an environment process can continue to send requests after /stop_rollout returns.
Use a work queue that continues querying children until no unvisited descendants remain. Kill the collected PIDs in reverse traversal order.

- all_pids = list(child_pids)

Ray documentation ray start worker before head address behavior
💡 Result:
In a multi-node Ray cluster, the head node must be started before any worker nodes [1][2][3]. The standard procedure is to run ray start --head on the intended head node first [1][2], which initializes the Global Control Store (GCS) and prints the connection address [4][1]. Worker nodes must then be started using ray start --address=<head-node-address>:<port> to connect to that specific GCS instance [4][1][2]. If you attempt to start a worker node before the head node is running, the worker will be unable to connect [4][1]. Specifically: 1. Connection Error: The worker process will fail to connect to the GCS at the specified address [4][1]. 2. Error Message: You will typically see an error such as Unable to connect to GCS at <address>:<port> [4][1][5]. This message explicitly advises users to verify that the Ray GCS is running at the specified address and that there are no network or firewall issues preventing the connection [4][1]. 3. Dependency: Worker nodes rely on the head node's GCS for cluster management, scheduling, and metadata, meaning they cannot participate in the cluster until the head node is active and reachable [6]. For automated cluster deployments (e.g., using the Ray Cluster Launcher or ray up), the orchestration logic typically handles this ordering automatically [7]. If you are manually managing an on-premises cluster, you must ensure the head node is successfully started and reachable from the worker machines before initiating the ray start commands on those workers [1][2].

Start the Ray head before the worker.
If users run these commands in order, the worker can fail because ray start --address requires a reachable Ray head. Move the ray start --head command before the worker command.

Align the PatchEval instructions with non-colocated scheduling.
env.rjob.sh configures 4 actor nodes × 8 GPUs and, with SLIME_COLOCATE=false, run_slime_generator.sh requests 8 dedicated rollout GPUs (2 per engine). The job therefore needs 40 GPUs across 5 nodes. The current 4-node, 32-GPU instructions cannot schedule the rollout workers.
Update the README hardware and Ray startup instructions to use four 8-GPU actor nodes plus one dedicated 8-GPU rollout node. Change SLIME_COLOCATE to false and remove the shared-GPU wording. Update the env.rjob.sh comments from 24 training GPUs across 3 nodes with CP=3 to 32 training GPUs across 4 nodes with CP=4. The executable allocation settings already match this topology.

Abort colocated startup when spread_placement fails.
In SLIME_COLOCATE=true mode, spread_placement must replace slime.ray.placement_group._create_placement_group so it selects SPREAD. The current handler only logs the import error, so training continues with the default PACK strategy and can hit duplicate-GPU/NCCL failures. Use SystemExit, because Python's sitecustomize loader suppresses ordinary exceptions.

Ray placement_group PACK SPREAD strategy bundles documentation scheduling semantics
💡 Result:
In Ray, placement groups are a mechanism for gang scheduling, allowing users to atomically reserve resources (organized as bundles) across nodes [1][2]. The scheduling strategy determines how these bundles are distributed across the cluster [1][3]. Ray supports four primary placement group strategies: 1. PACK (Default): Bundles are packed onto as few nodes as possible on a best-effort basis [1][4]. If strict packing is not feasible (i.e., the requested bundles exceed the capacity of a single node), Ray may distribute them across multiple nodes [1][2]. 2. STRICT_PACK: All bundles must be packed into a single node [4]. If the entire group cannot fit on one node, the creation of the placement group fails [1][2]. 3. SPREAD: Bundles are placed across distinct nodes as evenly as possible on a best-effort basis [4]. If strict spreading is not feasible, bundles may be placed on overlapping nodes [1][3]. 4. STRICT_SPREAD: Each bundle is required to be scheduled on a separate, distinct node [4][2]. When using placement groups, tasks or actors must explicitly utilize the PlacementGroupSchedulingStrategy to access the reserved resources [1][5]. It is important to note that while PACK aims for co-location, it does not strictly guarantee that bundles will be consolidated on one node unless STRICT_PACK is used [1][2]. Users seeking to ensure specific resource topology—such as for performance-sensitive distributed training or inference—should select the strategy that best matches their constraints, keeping in mind that "STRICT" variations provide hard guarantees at the cost of potential scheduling failure if resources are insufficient [1][5].

official Ray placement group PACK SPREAD strategy documentation
💡 Result:
In Ray, placement groups are used to reserve resources across multiple nodes (gang scheduling) and support four primary placement strategies to control how resource bundles are distributed [1][2]. These strategies are configured using the strategy argument in ray.util.placement_group [3][4]. The four supported strategies are: 1. PACK: A best-effort strategy that attempts to place all bundles onto as few nodes as possible [1][4]. If strict packing is not feasible (e.g., resources do not fit on a single node), bundles may be spread across other nodes [1][5]. This is the default strategy [1][6]. 2. SPREAD: A best-effort strategy that attempts to place bundles across distinct nodes as evenly as possible [3][4]. If strict spreading is not feasible, bundles may be placed on overlapping nodes [1][5]. 3. STRICT_PACK: A strict strategy that requires all bundles to be placed onto a single node [3][4]. If the bundles cannot be packed into one node, the placement group creation will fail [1][6]. 4. STRICT_SPREAD: A strict strategy that requires each bundle to be scheduled on a separate, distinct node [3][4]. These strategies allow users to balance resource locality and availability depending on the requirements of their tasks or actors [1][5]. While placement groups reserve the resources, tasks and actors must specifically use the PlacementGroupSchedulingStrategy to utilize the reserved resources [1][2].

Do not use PACK as the isolation control.
_patched_create_placement_group passes identical bundles to Ray and provides no training or rollout role constraints. Ray PACK is best-effort and can place both roles on one node when the topology does not align with the bundle boundary. Add role-aware placement constraints, or reject unsupported topologies.

Ray placement_group ready remove_placement_group actor kill cleanup official documentation
💡 Result:
To remove a placement group in Ray, use the ray.util.remove_placement_group API [1][2]. This API is asynchronous and is designed to free reserved resources (bundles) [1][3][4]. Key points regarding the removal of placement groups and actor cleanup: 1. Automatic vs. Manual Cleanup: By default, a placement group's lifetime is scoped to the driver or the detached actor that created it [1][3][5]. The reserved resources are automatically freed when the creating driver or detached actor exits [1][3]. For manual management, the remove_placement_group function is used [1][3][5]. 2. Actor Handling: When you call remove_placement_group, any actors or tasks currently using the placement group's reserved resources are forcefully killed [1][3]. 3. Graceful Termination Considerations: Ray does not currently provide a direct "graceful" removal flag for placement groups that waits for actors to finish their tasks [6]. If you need to perform cleanup for actors (such as saving state, closing database connections, or running custom shutdown logic), you must handle this manually before calling remove_placement_group [6]. This typically involves: - Requesting the actors to shut down gracefully (e.g., via a remote method call like actor.stop.remote) [6]. - Optionally waiting for those tasks to complete [6]. - Invoking ray.kill(actor) if necessary, or waiting for them to terminate after their graceful shutdown procedures [7][8]. - Finally, calling remove_placement_group to release the resources [1][3][6]. For individual actors, Ray provides the ray_shutdown method to handle graceful cleanup when an actor terminates, but this is triggered by the actor exiting (either naturally, through scope deletion, or via a termination signal) rather than being a built-in mechanism that pauses the placement group removal process [7][8].

Release placement resources on setup failure.
If placement_group() succeeds, an exception during readiness, InfoActor creation, or GPU-ID collection skips the success cleanup. The placement group and already-created actors can then remain alive until the creating driver exits. A same-driver retry can fail to acquire the reserved GPUs. Kill all created actors, call remove_placement_group(pg), and re-raise the original exception.

Do not stringify list content; this drops images from multimodal messages.
OpenAI multimodal messages carry list content:
content = [{"type": "text", ...}, {"type": "image_url", ...}]Lines 83-87 replace that list with a JSON string. rl/llm_proxy.py Line 202 calls normalize_messages before prepare_generate_input, so rl/mask/trajectory_mask_builder.py then receives a string. _convert_content_item_for_tokenization (Lines 172-193) never runs, process_vision_info([model_input_message]) (Line 370) returns no images, and image_data stays empty. The image is dropped from the rollout prompt and from the recorded trajectory.
Only convert content that is neither a string nor a list. This preserves the .startswith guard the docstring describes and keeps multimodal content intact.

Move the timing emission on/off switch into rl/timing_log.py itself instead of guarding every call site. - rl/timing_log.py: add module-level _enabled (default True, overridable via SAFACTORY_TIMING_LOG_ENABLED env, consistent with the existing SAFACTORY_TIMING_LOG path env) and set_enabled() for runtime control. emit() returns early when disabled. - gateway/telemetry.py & manager/simulation_worker.py: drop the per-call 'if _timing_emit is not None' guards; on import failure fall back to a noop lambda so call sites emit unconditionally. The switch now lives in timing_log, not behind scattered guards. RL runs keep timing on by default; non-RL callers can opt out with SAFACTORY_TIMING_LOG_ENABLED=0 or timing_log.set_enabled(False).

Pull the repeated llm_step timing emit (field extraction + _timing_emit call) out of enqueue_success/enqueue_failure into a single TelemetryRecorder._emit_llm_step helper. The two call sites now pass binding/stream_stats/response_body/error_text and let the helper build the event, so the shared field extraction lives once instead of twice. Emission gating stays inside timing_log (set_enabled / env). Co-authored-by: Cursor <cursoragent@cursor.com>

…K); add eval_elapsed_s to episode timing #1: GATEWAY_DEFAULT_MAX_TOKENS env var now read centrally in load_gateway_config instead of app.py; GatewayConfig.default_max_tokens defaults to 32768; app.py reads cfg.default_max_tokens via app.state.gateway_config. #4: store _eval_elapsed into result.metrics['eval_elapsed_s'] and include it in the episode timing emit for offline three-segment (startup/active/eval) analysis.

#3: capture the epoch second when the RJob first enters Running state inside wait_terminal (alongside the existing submit_to_running_ms), carry it out via trace.update_context, surface it through _attach_timing_metrics into result.metrics, and emit it in the episode timing record. rjob_running_ts - rjob_submit_ts yields cluster queue time.

…buffer fetch #6: eliminate the late-flip problem by cursing on job_environments.id instead of session_steps.id. Two-phase fetch: (1) discover finished envs with id > cursor, (2) fetch their terminal steps. Because mark_environment_finished is only called after all steps are is_terminal=True, finished=True guarantees all training-ready steps are terminal — no late flips, no lookback, no served_pks dedup. Both sqlite and cloud strategies implement fetch_finished_env_steps; buffer_server switches to the new cursor and drops FETCH_LOOKBACK/served_pks. Legacy fetch_done_steps_with_context kept for compatibility. Co-authored-by: Cursor <cursoragent@cursor.com>
…er_server, drop strategy changes Replaces per-strategy fetch_finished_env_steps/get_max_env_id (~200 lines) with existing DataManager APIs: list_environment_rows + new 12-line wrapper list_terminal_steps_for_sessions. _build_item_from_row accepts both mapped and raw dict keys. Net: -247 lines, +66 lines. Co-authored-by: Cursor <cursoragent@cursor.com>
