Walkthrough

Updated README/docs links to the new quickstart and flashinfer-trace paths; removed the examples/win_at_p.py example script; added CUDA-availability guards to some benchmark tests and a formatting tweak in an integration test.

Changes

Cohort / File(s) Change Summary
Documentation
README.md, docs/index.mdx
Updated Get Started/reference links: quick_startquickstart and ./flashinfer_trace/flashinfer_trace./flashinfer-trace.
Example removal
examples/win_at_p.py
Deleted the example Python script that computed win@p curves (parsing, grouping, baseline selection, CSV output, optional matplotlib plotting, and CLI).
Tests — benchmark guards
tests/bench/test_benchmark.py
Added CUDA-runtime guards (skipif checks) to four tests so they are skipped on systems without CUDA devices.
Tests — formatting
tests/integration/flashinfer/test_rmsnorm.py
Removed an initial blank line (format-only change).

Sequence Diagram(s)

(No sequence diagram provided — changes are documentation, test guards, and file removal; no runtime control-flow feature added.)

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

Areas to pay attention to:

  • Confirm README/docs link targets are correct and that relative paths resolve in the published site.
  • Ensure removal of examples/win_at_p.py doesn't break any referenced docs or CI tasks.
  • Verify the skipif conditions in tests/bench/test_benchmark.py use the intended CUDA-detection logic and that CI still runs the intended test coverage.

Poem

🐰 I hopped through docs to mend a link,
Pulled an old example from the brink,
Tests now skip where GPUs are scarce,
Quiet changes, tidy and terse —
A carrot nod for code that’s pink.

Pre-merge checks and finishing touches

✅ Passed checks (3 passed)
Check name Status Explanation
Description Check ✅ Passed Check skipped - CodeRabbit’s high-level summary is enabled.
Title Check ✅ Passed The pull request title "fix: fix quick start link and examples" directly aligns with the stated PR objectives to "update the link to quick start page; clean examples folder." The title accurately reflects the primary changes: fixing the quick start link references in README.md and docs/index.mdx (updating "quick_start" to "quickstart"), and cleaning the examples folder by removing examples/win_at_p.py. While the changeset includes secondary modifications to test files (blank line removal and CUDA guards), the instructions acknowledge that titles need not capture every detail. The title is concise, specific, and clearly conveys the main purpose of the changes.
Docstring Coverage ✅ Passed Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%.

44-46: Verify CUDA requirement for no-solutions test.

Similar to test_run_all_empty_traceset, this test has no solutions to execute, making the CUDA requirement non-obvious.


79-81: Verify CUDA requirement for CPU-targeted solution.

This test creates a solution with target_hardware=["cpu"] (line 100) and no workloads to execute. The CUDA guard seems potentially unnecessary given the CPU target.


121-123: Verify CUDA requirement for dump_traces test.

Another empty trace set test similar to test_run_all_empty_traceset. The CUDA requirement should be verified.


136-186: ****

No inconsistency exists. test_isolated_runner_runtime_error uses @patch to mock IsolatedRunner, preventing its __init__ from executing and thus no CUDA device enumeration occurs. In contrast, test_run_all_no_workloads instantiates the real Benchmark object, which creates a real IsolatedRunner that calls list_cuda_devices(), requiring the CUDA guard. The different approaches are correct by design.

Likely an incorrect or invalid review comment.


28-30: CUDA guards are justified and necessary—no changes required.

The skipif decorators are correct. The Benchmark class instantiates a runner in its __init__ method, which unconditionally calls fib_utils.list_cuda_devices(). This function calls torch.cuda.device_count() to enumerate available CUDA devices, requiring CUDA to be present even for empty trace sets. The test test_isolated_runner_runtime_error lacks the guard because it mocks the runner class, preventing the real initialization code from executing.

Code Review

This pull request updates a link in README.md and removes the examples/win_at_p.py script. I've provided feedback on the README.md change, as the updated link to the quick start guide appears inconsistent with the documentation's file name (quick_start.mdx), potentially causing a broken link. A code suggestion is provided to align them. The removal of the win_at_p.py example is a significant change; it would be beneficial for future reference to add more context in the pull request description regarding this deletion.

The link to the quick start guide has been changed to use quickstart, but the corresponding documentation file provided in the context is named quick_start.mdx. This inconsistency might lead to a broken link. If the URL path is derived from the filename, it should probably keep the underscore to match.

The updated paths reference non-existent files and directories, creating broken links.

The changes to docs/index.mdx update the paths to:

  • ./start/quickstart (line 23)
  • ./flashinfer-trace (line 25)

However, the actual files and directories still use the old names:

  • ./docs/start/quick_start.mdx (not quickstart)
  • ./docs/flashinfer_trace/ directory (not flashinfer-trace)

Either rename the files and directories to match the new paths, or revert the index.mdx changes to point to the existing paths.

In docs/index.mdx around line 23, the updated link "Get Started:
./start/quickstart" (and similar at line 25 for ./flashinfer-trace) points to
non-existent paths; restore or correct links to the actual files. Change the
links to the existing paths (./start/quick_start.mdx and ./flashinfer_trace/) or
alternatively rename the target files/directories to match the new slugs; update
only the index.mdx links if you prefer not to move files, ensuring relative
paths match the repository structure and verify the links resolve.

Update the path from ./flashinfer-trace to ./flashinfer_trace in docs/index.mdx line 25.

The updated path uses hyphens (./flashinfer-trace), but the actual directory in the repository uses underscores (docs/flashinfer_trace/). This breaks the documentation link. The directory exists at ./flashinfer_trace and contains the schema documentation files.

In docs/index.mdx around line 25, the link text uses the wrong path
'./flashinfer-trace' but the repository directory is './flashinfer_trace';
update the path to './flashinfer_trace' so the documentation link points to the
existing docs/flashinfer_trace/ directory.
