Inline comments:
In `@_internal-tools/bench.ts`:
- Around line 8-12: Move the call to getAllWorkspaceConfigs() into the try block
inside main() so any errors thrown by readDenoConfig/getAllWorkspaceConfigs()
are caught by the existing catch handler; specifically, in function main()
remove the top-level await of getAllWorkspaceConfigs() and call it after
entering the try (so the console.log and subsequent logic remain inside the
try), ensuring the catch block handles failures and triggers the existing
console.error + Deno.exit(1) path.
- Around line 10-24: Replace the bare console.* calls in the try/catch block
with globalThis.console.* so they comply with the no-console lint rule;
specifically update the console.log calls that reference workspaces (the
"Validating ...", "All workspace fixtures are valid!", "Benchmark execution
would start here..." and the runner placeholder lines) and the console.error in
the catch that prints errors thrown by validateFixturesOrThrow to use
globalThis.console.log / globalThis.console.error respectively.

- restrict dynamic import to file:// URLs - move async operations inside try block - comply with no-console lint rule - improve variable naming and formatting
|
Addressed final review feedback:
Dynamic import suppression is intentional, as the path is restricted to validated local file URLs and does not involve user input. |
|
Addressed all Codacy and CodeRabbit findings.
The remaining Codacy warnings appear to be false positives due to static analysis limitations on dynamic imports and cross-function error handling. Happy to adjust further if needed. |

This PR introduces fail-fast validation for benchmark fixtures to ensure that all workspaces provide the required
fixtures.tsimplementation before benchmark execution begins.The validation prevents silent gaps in benchmark coverage by enforcing consistency across all workspaces.
Changes
1. Fixture Validation System
Scans all workspaces at
deno task benchstartupVerifies existence of
fixtures.tsin each workspaceDynamically imports and validates required interface:
small()medium()large()Supports both named exports and default export object patterns
2. Fail-Fast Execution
3. Error Reporting Improvements
4. Cross-Platform Path Handling Fix
URL.pathnamewithfromFileUrl()to ensure correct filesystem path resolution\C:\...)5. CLI Feedback Enhancements
Example Output
Motivation
Previously, benchmark execution could proceed even when some workspaces lacked fixtures, leading to incomplete or misleading benchmark results.
This change enforces consistency and ensures that all workspaces participate in benchmarking, improving reliability and developer confidence.
