Summary

The PerfCI workloads pipeline was missing the Windows Server 2025 workload from its scheduled list, even though the rest of the wiring was already in place:

  • WINDOWS_SERVER_2025_URL = credentials('perfci_windows_server_2025_url') (line 25)
  • case "windows_vm_scale_windows_server_2025" in the workload switch (line 154)

Because windows_vm_scale_windows_server_2025 was absent from the workloads list, the case was dead code and the workload never ran.

Change

jenkins/PerfCI/03_PerfCI_Workloads_Deployment/Jenkinsfile

  • Add 'windows_vm_scale_windows_server_2025' to the workloads list, after windows_vm_scale_windows_server_2022.

This matches how .github/workflows/Nightly_Perf_Env_CI_Scale.yml already runs the same workload.

Testing

  • PYTHONPATH=. python3 -m pytest -q tests/unittest/ → 39 passed
  • No code or template changes; the new entry reuses the existing parsing path (parts[0] + "_" + parts[1] → windows_vm, RUN == "scale"), the existing switch case, and the existing credential.

Summary by CodeRabbit

  • New Features
    • Added support for deploying the Windows Server 2025 scale workload in the performance CI pipeline.
  • Bug Fixes
    • Fixed retries for scale workloads so they continue using the correct workload-specific behavior after an earlier attempt fails. This helps ensure repeated attempts run consistently and produce reliable performance test results.

Walkthrough

The deployment workload list now includes windows_vm_scale_windows_server_2025. Each retry restores the original workload name before parsing.

Changes: Windows scale workload deployment

The deployment workload list includes windows_vm_scale_windows_server_2025. Each retry resets the workload name to its original value before parsing. This preserves scale-specific parsing on retries.

Preserve the workload name across retries.

If the 2025 scale run fails after warm-up, the next attempt passes an empty SCALE. A successful single-VM run can then mark the scale workload as successful.

Restore workload from originalWorkload at the start of each attempt.

[Claude Code] Addressed in e2941cd.

workload is now restored from originalWorkload at the start of every retry attempt:

for (int i = 0; i < retryCount && !success; i++) {
    // A previous attempt reassigns workload to the base name, so restore it
    // before parsing: otherwise a retried scale workload runs as its non-scale
    // variant and can be reported as successful
    workload = originalWorkload
    try {

A retried *_scale workload now re-parses as the scale variant instead of falling into the non-scale branch with SCALE="", so a failed scale run can no longer be masked by a passing single-VM retry.

Fixed in this PR rather than a follow-up because it directly affects the new windows_vm_scale_windows_server_2025 entry; note that it applies to every *_scale workload in the list.

Add windows_vm_scale_windows_server_2025 to the workloads list so the
Windows Server 2025 scale run is scheduled alongside the 2022 one.

Also restore workload from originalWorkload at the start of every retry
attempt: a previous attempt reassigns workload to its base name, so a
retried scale workload ran as the non-scale variant with an empty SCALE
and could be reported as successful.

[Claude Code] Squashed into a single commit (29a2f93) and force-pushed.

The commit now contains both changes:

  • windows_vm_scale_windows_server_2025 added to the workloads list.
  • The retry fix you reported: workload = originalWorkload at the start of every attempt in the retry loop, so a retried *_scale workload re-parses as the scale variant instead of running as the non-scale one with SCALE="".
