[TRTLLM-7101][infra] Reuse passed tests

[yiqingy0]

Summary by CodeRabbit

• Chores

  • Downstream L0 tests can now opt to reuse prior build artifacts to speed CI runs.
  • Test runs can skip previously passed tests when a reuse artifact path is provided, reducing redundant execution.
  • Added a utility to extract passed test names and update test lists automatically.

• Tests

  • One end-to-end test is currently forced to fail, causing a deterministic test failure.

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

Passes reuseBuild into downstream L0 launches, adds conditional reuse of prior test results by downloading and pruning passed tests, introduces a CLI Python utility to extract/remove passed tests from JUnit results, and makes an integration test fail immediately.

Changes

Cohort / File(s)	Summary
Pipeline fan-out parameterization jenkins/L0_MergeRequest.groovy	Replaced literal false with reuseBuild when calling launchJob for downstream L0 jobs (x86_64 and SBSA single/multi-GPU) so the downstream job can receive reuseBuild and optionally set reuseArtifactPath.
L0 test reuse flow jenkins/L0_Test.groovy	Adds REUSE_ARTIFACT_PATH = env.reuseArtifactPath and a new function def reusePassedTests(pipeline, llmSrc, reusedArtifactPath, stageName, testListFile). When REUSE_ARTIFACT_PATH is set, code downloads previous results, extracts passed tests, and removes them from the current test list in both Slurm multi-node and platform run paths; adds logging and error handling; call sites updated to pass llmSrc.
Result reuse utility script jenkins/scripts/reuse_passed_tests.py	New script with get_passed_tests(input_file, output_file) and remove_passed_tests(input_file, passed_tests_file) plus a small argparse CLI. Parses JUnit XML to list passed tests and filters them from a test list; imports test_rerun.parse_name.
Integration test behavior change tests/integration/defs/test_e2e.py	test_openai_chat_example now immediately calls pytest.fail("test_openai_chat_example"), causing a deterministic early test failure.

1042-1042: Verify reuseBuild is a valid build number or handled as a sentinel

Forwarding reuseBuild to launchJob(...) is fine, but confirm upstream only supplies a numeric build ID, null, or a known sentinel (e.g., "latest"). A non-numeric value may produce an invalid reuseArtifactPath.

• Location to check:

  • jenkins/L0_MergeRequest.groovy — line ~1042
  • Snippet:

    launchJob("L0_Test-x86_64-Single-GPU", reuseBuild, enableFailFast, globalVars, "x86_64", additionalParameters)
    

• Recommended hardening for launchJob(...):

  • Accept reuseBuild values: null (derive last successful), "latest" (treat as last successful), or a numeric build ID.
  • Validate before constructing paths (e.g., numeric check via regex /^\d+$/ or try Integer.parseInt; or use reuseBuild.isInteger() where appropriate). If invalid, skip reuse and log a warning.
  • Also validate/whitelist inputs from the upstream bot if possible.

I can provide a small patch to implement these guards if you want.

---

1098-1098: Incorrect — reuseBuild is already validated in launchJob; no extra check needed for the Multi-GPU call

launchJob(...) guards construction of reuseArtifactPath with a truthy check on reuseBuild, so passing reuseBuild into the Multi-GPU invocation is safe.

• jenkins/L0_MergeRequest.groovy: def launchJob(...) at line 969 — validates reuseBuild before setting parameters['reuseArtifactPath'] (lines ~995–996).
• jenkins/L0_MergeRequest.groovy: Multi-GPU invocation at line 1098 — launchJob("L0_Test-x86_64-Multi-GPU", reuseBuild, ...)

If you want "default to last successful pipeline" behavior when reuseBuild is omitted, that’s a separate behavior change to implement intentionally.

Likely an incorrect or invalid review comment.

---

1200-1200: No change needed — SBSA multi‑GPU already has the same reuse/guard logic

Short verification: I inspected jenkins/L0_MergeRequest.groovy — the SBSA test path contains the same gating and error/commit-guard behaviour as the x86 path (it tracks singleGpuTestFailed, checks requireMultiGpuTesting, blocks multi‑GPU when single‑GPU failed except on PostMerge, then calls launchJob with reuseBuild).

Relevant locations:

• jenkins/L0_MergeRequest.groovy — reuseBuild set from gitlab params (around line ~134)
• launchJob(...) definition (around line ~969)
• x86 multi‑GPU gating & launch (around lines ~1098)
• SBSA single‑GPU gating, requireMultiGpuTesting check and the multi‑GPU launch (launchJob("L0_Test-SBSA-Multi-GPU", ...) at line 1200; gating logic just above)

Action: Ignore the original suggestion to replicate reuse/commit‑guard logic — it’s already present.

Likely an incorrect or invalid review comment.

74-95: Replace brittle sys.argv dispatch with argparse subparsers; fix help text mismatch

1-95: Confirm exit-code semantics for missing files

Currently, missing files print a message and return 0 (success). This may be intentional in the reuse-artifacts flow (no-op when artifacts are absent). Please confirm the desired behavior so CI logic relying on command success/failure remains correct.

If you prefer non-zero exit codes for specific failure modes, I can wire that in and update the Groovy caller(s) accordingly.

---

1-95: Add minimal unit tests for core logic

Recommend adding small unit tests for:

• JUnit root being vs
• Handling of passed/failure/error/skipped
• remove_passed_tests filtering, including blank lines and duplicates

I can scaffold pytest-based tests under a tests/ folder and wire into CI if you want.

354-357: Pass required context into reusePassedTests (pipeline, llmSrc) to avoid runtime failures.

The current implementation of reusePassedTests references pipeline and llmSrc internally but they aren’t in scope. Pass both explicitly from here. Also aligns with the corrected function signature below.

-                // Reuse passed tests
-                if (REUSE_ARTIFACT_PATH) {
-                    reusePassedTests(REUSE_ARTIFACT_PATH, stageName, testListPath)
-                }
+                // Reuse passed tests
+                if (REUSE_ARTIFACT_PATH) {
+                    reusePassedTests(this, llmSrcLocal, REUSE_ARTIFACT_PATH, stageName, testListPath)
+                }

1452-1456: Pass context to reusePassedTests here as well (pipeline and llmSrc).

Mirror the fix from the multinode path so both call sites are consistent and functional.

-        // Reuse passed tests
-        if (REUSE_ARTIFACT_PATH) {
-            reusePassedTests(REUSE_ARTIFACT_PATH, stageName, testDBList)
-        }
+        // Reuse passed tests
+        if (REUSE_ARTIFACT_PATH) {
+            reusePassedTests(this, llmSrc, REUSE_ARTIFACT_PATH, stageName, testDBList)
+        }

1072-1105: Fix undefined vars, quoting, logging, backup path, and wrong helper-script name in reusePassedTests

Verified:

• jenkins/scripts/reuse_passed_tests.py exists and defines get_passed_tests (line 9) and remove_passed_tests (line 42).
• jenkins/L0_Test.groovy currently references delete_passed_tests.py (matches at lines 1082 and 1093) and uses undefined variables pipeline and llmSrc.

Actionable changes (apply the refactor below; it switches to reuse_passed_tests.py and fixes signature, quoting, logging, and backup):

• Files to update:
  • jenkins/L0_Test.groovy (function reusePassedTests, ~lines 1072–1105; references at 1082 & 1093)
  • Ensure calls point to jenkins/scripts/reuse_passed_tests.py

Notes:

• Verified helper script is reuse_passed_tests.py (CLI functions get_passed_tests/remove_passed_tests exist). Update the Groovy calls to that script (replaces delete_passed_tests.py).
• Signature change required: accept pipeline and llmSrc as parameters.
• Quoting and echo usage prevent shell injection and broken outputs; backup now uses .orig suffix next to original file.

🧹 Nitpick comments (1)

jenkins/L0_Test.groovy (1)

28-29: Initialize REUSE_ARTIFACT_PATH defensively (trim to avoid false positives).

Minor: trim any accidental whitespace so the boolean checks behave predictably.

-REUSE_ARTIFACT_PATH = env.reuseArtifactPath
+REUSE_ARTIFACT_PATH = env.reuseArtifactPath?.trim()
