GitHub Bot Help

/bot [-h] ['run', 'kill', 'skip', 'reuse-pipeline'] ...

Provide a user friendly way for developers to interact with a Jenkins server.

Run /bot [-h|--help] to print this help message.

See details below for each supported subcommand.

Details

run [--reuse-test (optional)pipeline-id --disable-fail-fast --skip-test --stage-list "A10-PyTorch-1, xxx" --gpu-type "A30, H100_PCIe" --test-backend "pytorch, cpp" --add-multi-gpu-test --only-multi-gpu-test --disable-multi-gpu-test --post-merge --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" --detailed-log --debug(experimental)]

Launch build/test pipelines. All previously running jobs will be killed.

--reuse-test (optional)pipeline-id (OPTIONAL) : Allow the new pipeline to reuse build artifacts and skip successful test stages from a specified pipeline or the last pipeline if no pipeline-id is indicated. If the Git commit ID has changed, this option will be always ignored. The DEFAULT behavior of the bot is to reuse build artifacts and successful test results from the last pipeline.

--disable-reuse-test (OPTIONAL) : Explicitly prevent the pipeline from reusing build artifacts and skipping successful test stages from a previous pipeline. Ensure that all builds and tests are run regardless of previous successes.

--disable-fail-fast (OPTIONAL) : Disable fail fast on build/tests/infra failures.

--skip-test (OPTIONAL) : Skip all test stages, but still run build stages, package stages and sanity check stages. Note: Does NOT update GitHub check status.

--stage-list "A10-PyTorch-1, xxx" (OPTIONAL) : Only run the specified test stages. Examples: "A10-PyTorch-1, xxx". Note: Does NOT update GitHub check status.

--gpu-type "A30, H100_PCIe" (OPTIONAL) : Only run the test stages on the specified GPU types. Examples: "A30, H100_PCIe". Note: Does NOT update GitHub check status.

--test-backend "pytorch, cpp" (OPTIONAL) : Skip test stages which don't match the specified backends. Only support [pytorch, cpp, tensorrt, triton]. Examples: "pytorch, cpp" (does not run test stages with tensorrt or triton backend). Note: Does NOT update GitHub pipeline status.

--only-multi-gpu-test (OPTIONAL) : Only run the multi-GPU tests. Note: Does NOT update GitHub check status.

--disable-multi-gpu-test (OPTIONAL) : Disable the multi-GPU tests. Note: Does NOT update GitHub check status.

--add-multi-gpu-test (OPTIONAL) : Force run the multi-GPU tests in addition to running L0 pre-merge pipeline.

--post-merge (OPTIONAL) : Run the L0 post-merge pipeline instead of the ordinary L0 pre-merge pipeline.

--extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" (OPTIONAL) : Run the ordinary L0 pre-merge pipeline and specified test stages. Examples: --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx".

--detailed-log (OPTIONAL) : Enable flushing out all logs to the Jenkins console. This will significantly increase the log volume and may slow down the job.

--debug (OPTIONAL) : Experimental feature. Enable access to the CI container for debugging purpose. Note: Specify exactly one stage in the stage-list parameter to access the appropriate container environment. Note: Does NOT update GitHub check status.

For guidance on mapping tests to stage names, see docs/source/reference/ci-overview.md
and the scripts/test_to_stage_mapping.py helper.

kill

kill

Kill all running builds associated with pull request.

skip

skip --comment COMMENT

Skip testing for latest commit on pull request. --comment "Reason for skipping build/test" is required. IMPORTANT NOTE: This is dangerous since lack of user care and validation can cause top of tree to break.

reuse-pipeline

reuse-pipeline

Reuse a previous pipeline to validate current commit. This action will also kill all currently running builds associated with the pull request. IMPORTANT NOTE: This is dangerous since lack of user care and validation can cause top of tree to break.

📝 Walkthrough

Walkthrough

RPC infrastructure hardening for resilience and graceful shutdown. Changes include immediate shutdown with request cancellation semantics, improved event loop startup reliability via increased delays and synchronization, centralized error handling helpers, and removal of test waivers with enhanced resource cleanup patterns.

Changes

Cohort / File(s) Summary
RPC Client Startup Resilience
tensorrt_llm/executor/rpc/rpc_client.py
Increased initial sleep delays (0.1s → 0.2s) in _ensure_event_loop and run_loop(). Added lazy response reader startup with non-blocking deferral and try/except around loop-start logic to prevent exception propagation.
RPC Server Shutdown & Cancellation
tensorrt_llm/executor/rpc/rpc_server.py
Changed shutdown to immediate cancellation instead of waiting for pending work. Added internal helpers: _cancel_pending_queue_requests, _send_error_response, _handle_shutdown_request. Integrated RPCCancelled checks before and during request processing; streaming requests trigger cancellation on shutdown detection. Updated error handling to differentiate streaming vs. non-streaming responses.
RPC Proxy Synchronization & Robustness
tensorrt_llm/executor/rpc_proxy.py
Added main_loop_started Event for synchronization; early response reader startup with explicit readiness check. Wrapped RPC submission with try/except for _results cleanup. Enhanced shutdown robustness via hasattr checks and exception handling around MPI session, RPC client close, and main loop cancellation with timeout-based thread join. Simplified main loop task composition.
Test Resource Cleanup & Skip Removal
tests/unittest/executor/test_rpc.py, tests/unittest/executor/test_rpc_proxy.py, tests/unittest/executor/test_rpc_worker.py
Replaced context-managed client/server cleanup with explicit construction, try/finally blocks, and ordered shutdown/close sequences. Updated test assertions to expect RPCCancelled behavior on shutdown. Removed skip decorators to enable previously skipped tests; added skip marker for flaky performance test. Changed address generation to unique IPC addresses.
Test Waivers Reduction
tests/integration/test_lists/waives.txt
Removed multiple SKIP entries for tests under unittest/executor and unittest/llmapi, reducing waived test exclusions.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~60 minutes

  • rpc_server.py: Requires careful analysis of new request cancellation flow, integration of _handle_shutdown_request across all request paths, and error handling differentiation between streaming/non-streaming modes
  • rpc_proxy.py: Multiple synchronization mechanisms, shutdown robustness with error handling, and state management during initialization and cleanup
  • rpc_client.py: Timing-sensitive logic changes and lazy initialization; verify no race conditions introduced
  • Test files: Validate that new cleanup patterns properly release resources and that removed skip decorators don't mask underlying flakiness beyond the explicitly marked performance test

Either add 1s headroom or fix the comment. Adding headroom matches intent and avoids client timing out before server’s timeout response arrives.

🧹 Nitpick comments (10)
tensorrt_llm/executor/rpc/rpc_client.py (2)

254-271: Reader startup robustness: narrow exception and log stack.

Logic is good; avoid blind except Exception and log traceback for diagnosis.

-        except Exception as e:
-            logger_debug(f"Error starting response reader: {e}")
+        except (RuntimeError, asyncio.CancelledError) as e:
+            logger_debug(f"Error starting response reader: {e}")
+        except Exception:
+            logger.exception("Error starting response reader")
             # Don't raise here, let it retry on next call
             self._reader_task = None

Ruff BLE001.


359-359: Replace fixed sleep with readiness wait.

Poll is_running() with a short backoff and timeout instead of a magic 0.2s.

-            # Give the loop a moment to start
-            time.sleep(0.2)
+            # Wait for the loop to start running (max 1s)
+            waited = 0.0
+            while not self._loop.is_running() and waited < 1.0:
+                time.sleep(0.01)
+                waited += 0.01
tests/unittest/executor/test_rpc.py (4)

217-229: Test semantics: create pendings before shutdown.

This test now enqueues requests after triggering shutdown. To validate “pending requests are cancelled when server shuts down,” enqueue first, then shutdown.

-        client = RPCClient(addr)
-        try:
-            client.shutdown_server()
-            pending_futures = [client.task().remote_future() for _ in range(10)]
+        client = RPCClient(addr)
+        try:
+            pending_futures = [client.task().remote_future() for _ in range(10)]
+            client.shutdown_server()

284-297: Ensure deterministic server teardown.

After remote shutdown, explicitly call server.shutdown() locally to join the dispatcher instead of relying on sleep(1.0).

-    finally:
-        # Wait for the server dispatcher thread to quit
-        time.sleep(1.0)
+    finally:
+        # Join dispatcher deterministically
+        server.shutdown()

299-301: Track flaky test with an issue ID.

Add a reference (issue/URL) to the skip reason to avoid permanent skip.

-@pytest.mark.skip(reason="This test is flaky, need to fix it")
+@pytest.mark.skip(reason="Flaky; tracked in ISSUE-XXXX: fix perf timing nondeterminism")

375-393: Teardown order and sleeps.

Good: server first, then client. Prefer joining or polling over fixed sleep(1.0) to shorten tests and reduce flakiness.

-        # Wait longer to ensure all background threads exit completely
-        time.sleep(1.0)
+        # Optional: poll for thread shutdown instead of fixed sleep
+        # e.g., wait up to 1s in 20 * 50ms steps if available
tensorrt_llm/executor/rpc_proxy.py (4)

67-77: Avoid inner import; consider public starter.

  • Remove inner import time; use the module-level import.
  • Using a private _start_response_reader_lazily is brittle; consider exposing a public ensure_reader_started() on RPCClient later.
-        if hasattr(self.rpc_client, '_start_response_reader_lazily'):
-            self.rpc_client._start_response_reader_lazily()
-            # Give response reader time to start
-            import time
-            time.sleep(0.1)
+        if hasattr(self.rpc_client, '_start_response_reader_lazily'):
+            self.rpc_client._start_response_reader_lazily()
+            time.sleep(0.1)  # Give response reader time to start

298-320: Register result before submit; drop unused exception var and log.

  • Great race fix moving registration before send.
  • Remove unused e and log with traceback if needed.
-        except Exception as e:
+        except Exception:
             # Clean up on error
             self._results.pop(client_id, None)
-            raise
+            logger.exception("submit() failed")
+            raise

Ruff F841.


346-364: Shutdown: avoid blind except, prefer logger.exception.

Use specific exceptions where possible, or at least log stack traces.

-            except Exception as e:
-                logger.warning(f"Error during main loop shutdown: {e}")
+            except Exception:
+                logger.exception("Error during main loop shutdown")
-            except Exception as e:
-                logger.warning(f"Error during MPI session shutdown: {e}")
+            except Exception:
+                logger.exception("Error during MPI session shutdown")
-        except Exception as e:
-            logger.warning(f"Error during RPC client close: {e}")
+        except Exception:
+            logger.exception("Error during RPC client close")

Ruff BLE001.


369-373: Remove f-strings without placeholders.

Ruff F541: unnecessary f prefix.

-                logger_debug(f"Shutting down mpi session", color="yellow")
+                logger_debug("Shutting down mpi session", color="yellow")
-                logger_debug(f"Mpi session shutdown", color="yellow")
+                logger_debug("Mpi session shutdown", color="yellow")

**/*.py: Python code must target Python 3.8+.
Indent Python code with 4 spaces; do not use tabs.
Maintain module namespace when importing; prefer 'from package.subpackage import foo' then 'foo.SomeClass()' instead of importing the class directly.
Python filenames should be snake_case (e.g., some_file.py).
Python classes use PascalCase names.
Functions and methods use snake_case names.
Local variables use snake_case; prefix 'k' for variables that start with a number (e.g., k_99th_percentile).
Global variables use upper SNAKE_CASE prefixed with 'G' (e.g., G_MY_GLOBAL).
Constants use upper SNAKE_CASE (e.g., MY_CONSTANT).
Avoid shadowing variables from an outer scope.
Initialize all externally visible members of a class in the constructor.
Prefer docstrings for interfaces that may be used outside a file; comments for in-function or file-local interfaces.
Use Google-style docstrings for classes and functions (Sphinx-parsable).
Document attributes and variables inline so they render under the class/function docstring.
Avoid reflection when a simpler, explicit approach suffices (e.g., avoid dict(**locals()) patterns).
In try/except, catch the most specific exceptions possible.
For duck-typing try/except, keep the try body minimal and use else for the main logic.

472-481: LGTM: validates RPCCancelled on in-flight future after shutdown.

tensorrt_llm/executor/rpc_proxy.py (2)

109-111: LGTM: handle RPCCancelled explicitly in fetch loop.


140-166: Main loop readiness signal: good; keep wait bounded.

The event-based readiness + 5s wait is solid; nothing to change.

tensorrt_llm/executor/rpc/rpc_server.py (3)

248-266: LGTM: centralized error response helper is clear and correct.


289-301: LGTM: respect shutdown in worker loop before processing.


446-485: LGTM: graceful streaming cancellation on shutdown.

Minor: Ruff TRY003 suggests moving long messages into exception types, but acceptable as-is.

The performance results of some kernels could be easily affected by the warm/cold L2 cache status. To achieve more precise profiling results, the L2 cache is cleared for every execution by the circular buffer method for better benchmarking during autotuning.

Before this commit, the kv cache manager does the same regardless, which causes a mis-calculation in free memory available to allocate for the KV cache manager, hence causing a crash.

This commit fixes this by letting KV cache manager initialization be aware whether it is doing the dry run or not. If it is a dry run, use the max_tokens setting that is already pre-calculated and filled into kv_cache_config.max_tokens.
