@jiridanek: The enhanced tests in the second commit don't pass. I've split out the core of the work (first commit) into a separate PR that I'm looking into merging

Summary

This PR disables PDF export functionality for s390x (IBM Z) architecture in Jupyter Minimal images for both Python 3.11 and 3.12 versions due to known compatibility issues with this feature on s390x.

Changes Made

1. Modified jupyter/utils/install_pdf_deps.sh

  • Added early exit for s390x architecture detection using uname -m
  • PDF export dependencies (TexLive and Pandoc) are now skipped for s390x

2. Updated ci/cached-builds/gen_gha_matrix_jobs.py

  • Added jupyter-minimal-ubi9-python-3.11 and jupyter-minimal-ubi9-python-3.12 to S390X_COMPATIBLE set
  • Enables s390x builds for these minimal Jupyter images in CI pipeline

3. Modified tests/containers/workbenches/jupyterlab/jupyterlab_test.py

  • Added architecture detection to test_pdf_export test
  • Test now skips PDF export functionality for s390x architecture
  • Prevents test failures on s390x where PDF export is intentionally disabled

Testing

  • Local testing completed for both Python 3.11 and 3.12 versions
  • Images build successfully on s390x without PDF export dependencies
  • PDF export continues to work on other architectures (x86_64, arm64)
  • Test suite passes with architecture-aware PDF export test

Impact

  • s390x: PDF export functionality is disabled (as intended)
  • Other architectures: No change - PDF export continues to work normally
  • CI/CD: s390x builds are now enabled for Jupyter Minimal images

Validation

  • Github CI Validation

Walkthrough

This change updates s390x platform support by adding new compatible targets in the CI matrix generator, conditionally skipping PDF dependency installation on s390x in a shell script, and skipping the PDF export test on unsupported architectures in the JupyterLab test suite. It also introduces centralized architecture support configuration and utility functions for architecture detection and feature support checks in container tests.

Changes

Hi @Nash-123. Thanks for your PR.

I'm waiting for a opendatahub-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

🧹 Nitpick comments (2)
jupyter/utils/install_pdf_deps.sh (1)

20-24: LGTM! Clean approach to disable PDF dependencies on s390x.

The early exit prevents unnecessary TexLive and Pandoc installation on s390x architecture. The exit status 0 correctly indicates successful completion of the script's intended behavior.

Consider using the already-computed ARCH variable for consistency:

-if [[ "$(uname -m)" == "s390x" ]]; then
+if [[ "${ARCH}" == "s390x" ]]; then
tests/containers/workbenches/jupyterlab/jupyterlab_test.py (1)

61-68: Architecture detection works but could be optimized.

The logic correctly skips PDF export tests on s390x architecture. However, starting and stopping the container twice (once for architecture detection, once for the actual test) adds unnecessary overhead.

Consider checking architecture after the main container start to avoid double start/stop:

-        # Skip if we're running on s390x architecture
-        container.start(wait_for_readiness=False)
-        try:
-            exit_code, arch_output = container.exec(["uname", "-m"])
-            if exit_code == 0 and arch_output.decode().strip() == "s390x":
-                pytest.skip("PDF export functionality is not supported on s390x architecture")
-        finally:
-            docker_utils.NotebookContainer(container).stop(timeout=0)
         test_file_name = "test.ipybn"
         # ... test_file_content ...
         try:
             container.start(wait_for_readiness=True)
+            # Skip if we're running on s390x architecture
+            exit_code, arch_output = container.exec(["uname", "-m"])
+            if exit_code == 0 and arch_output.decode().strip() == "s390x":
+                pytest.skip("PDF export functionality is not supported on s390x architecture")
             # ... rest of test logic ...

36-37: LGTM! Correctly enables s390x builds for Jupyter Minimal images.

The addition of these two targets to the S390X_COMPATIBLE set properly enables CI builds for Jupyter Minimal images on s390x architecture, aligning with the broader PR objective of supporting s390x while disabling PDF export functionality on this platform.

59-63: Acknowledge interim architecture detection approach.

This implementation correctly integrates architecture-aware testing but still uses the container start/stop approach for architecture detection that was identified as inefficient in our previous discussion.

While this works for the current PR objectives, Issue #1576 tracks the systematic improvements for more efficient session-level caching and centralized configuration that we discussed.

59-63: Fix formatting and acknowledge architecture improvement.

Great implementation of the centralized architecture detection! This aligns perfectly with the systematic improvements discussed in Issue #1576.

However, there's a minor formatting issue to fix:

-        if not is_feature_supported(container_architecture,"pdf_export"):
+        if not is_feature_supported(container_architecture, "pdf_export"):

Learning: In the opendatahub-io/notebooks repository, the test runner's Python version (configured in GitHub Actions UV setup) intentionally doesn't need to match the Python version of the container images being tested. jiridanek's team uses Python 3.12 for running tests while images may use different Python versions (like 3.11), and this approach works fine since the test code is separate from the application code running inside the containers.

🔇 Additional comments (3)
tests/containers/architecture_utils.py (3)

1-7: Well-structured module setup.

Clear module documentation and appropriate imports for the architecture detection functionality.


9-19: Consider scope optimization in future iterations.

The implementation correctly handles architecture detection with proper cleanup. However, the function scope means a container is started/stopped for each test using this fixture.

This aligns with Issue #1576 for future optimization to session-level caching to improve test performance.


21-27: Well-designed helper functions.

Clean interface for architecture-specific feature checking with sensible defaults:

  • is_feature_supported defaults to True (assumes support unless explicitly limited)
  • get_architecture_limitation_reason provides descriptive error messages with fallback

🧩 Analysis chain

@jiridanek I'll review the changes in this PR that disables PDF export for s390x architecture in Jupyter Minimal images.


🏁 Script executed:

#!/bin/bash
# First, let's examine the key files that were modified to understand the implementation
echo "=== Reviewing install_pdf_deps.sh changes ==="
cat jupyter/utils/install_pdf_deps.sh

echo -e "\n=== Reviewing CI configuration changes ==="
cat ci/cached-builds/gen_gha_matrix_jobs.py | grep -A 10 -B 10 "S390X_COMPATIBLE"

echo -e "\n=== Reviewing test architecture support files ==="
cat tests/containers/architecture_support.py

echo -e "\n=== Reviewing architecture utilities ==="
cat tests/containers/architecture_utils.py

echo -e "\n=== Reviewing test modifications ==="
grep -A 20 -B 5 "test_pdf_export" tests/containers/workbenches/jupyterlab/jupyterlab_test.py

Length of output: 7176


The implementation looks excellent! This is a clean, well-structured solution that properly addresses the s390x compatibility issue. Here are my observations:

Strong Implementation Points:

  1. Clean Early Exit Pattern: The install_pdf_deps.sh script properly detects s390x architecture early and exits gracefully with a clear message.

  2. Centralized Architecture Configuration: The new architecture_support.py provides excellent centralization of architecture-specific limitations with clear reasoning - this is great design for maintainability.

  3. Proper CI Integration: Simple and correct addition of the jupyter-minimal images to the S390X_COMPATIBLE set.

  4. Smart Test Architecture: The conditional test skipping with clear messages ensures tests don't fail on unsupported architectures while maintaining coverage on supported ones.

🔍 Minor Observation:

The current architecture detection approach starts and stops a container for each test that needs architecture information. While functional, this could be optimized for performance if architecture detection becomes more widely used across tests.


🏁 Script executed:

#!/bin/bash
# Check if there are other tests that might benefit from architecture detection
echo "=== Checking for other potential architecture-dependent tests ==="
rg -n "uname.*-m|architecture|arch.*detect" tests/ --type py -A 2 -B 2

echo -e "\n=== Checking if architecture detection pattern is used elsewhere ==="
rg -n "container_architecture" tests/ --type py -A 3 -B 3

Length of output: 6933


Perfect! The analysis confirms this is a focused, well-implemented solution. Currently, the container_architecture fixture is only used for the PDF export test, so the performance consideration I mentioned is not a concern at this scale.

🎯 Final Assessment:

This PR excellently demonstrates:

  • Clean Architecture: Centralized configuration with clear separation of concerns
  • Proper Error Handling: Graceful early exits with informative messages
  • Smart Test Design: Architecture-aware conditional execution
  • Future-Friendly: The infrastructure can easily support other architecture-specific features

The implementation follows best practices and solves the s390x compatibility issue effectively without adding unnecessary complexity.

🚀 Ready for Merge

This is a solid implementation that properly enables s390x builds for Jupyter Minimal images while maintaining functionality on other architectures. The code is clean, well-documented, and follows good engineering practices.

Optional Follow-up: If architecture detection becomes more widely used across tests in the future, we could optimize the performance by implementing session-level caching or centralized architecture detection. Would you like me to create a follow-up issue for potential architecture detection efficiency improvements?
