fix(setup-js): wrap all sync fs calls in try/catch (eslint-monster remediation) by Copilot · Pull Request #46102 · github/gh-aw

Copilot · 2026-07-17T00:02:57Z

120 ESLint warnings for gh-aw-custom/require-fs-sync-try-catch and gh-aw-custom/require-mkdirsync-try-catch across 55 files in actions/setup/js/ — all unguarded synchronous filesystem operations that would crash the action on I/O errors.

Changes

Critical paths (readFileSync, writeFileSync, mkdirSync for required action state) — rethrow with descriptive message and { cause: err }:

try{fs.mkdirSync(manifestDir,{recursive: true});fs.writeFileSync(manifestPath,JSON.stringify(manifest));}catch(err){thrownewError(`Failed to write manifest to ${manifestPath}: ${err.message}`,{cause: err});}

Non-critical log appends (appendFileSync to GitHub Actions output/log files) — silent catch to avoid crashing the action over a logging failure:
```
try{fs.appendFileSync(githubOutput,content);}catch{/* ignore */}
```
Inline usages — extracted to an intermediate variable before wrapping, e.g. JSON.parse(fs.readFileSync(...)) split into a guarded read + separate parse.

Covers all files listed in the issue plus all other files surfaced by the lint run.

Hey @app/copilot-swe-agent 👋 — great work wrapping all those unguarded readFileSync/writeFileSync/mkdirSync calls across 55 files in actions/setup/js/! This is solid defensive programming that prevents crashes on I/O errors.

One thing that would help reviewers gain confidence:

Consider tests — this PR touches critical paths like create_pull_request.cjs and start_mcp_gateway.cjs. Even smoke-level tests verifying that the error-throw and silent-catch paths behave as expected would go a long way.

If you'd like a hand, you can assign this prompt to your coding agent:

Add tests for the try/catch wrappers introduced in actions/setup/js/ for the most critical files:
- create_pull_request.cjs: verify that a writeFileSync failure throws with a descriptive message and { cause: err }
- start_mcp_gateway.cjs: verify that an mkdirSync failure is surfaced correctly
Follow the existing test patterns in the actions/setup/js/ test directory.

Pull request overview

This PR hardens the JavaScript “setup” action helpers under actions/setup/js/ by wrapping synchronous filesystem operations in try/catch blocks to satisfy the gh-aw-custom/require-fs-sync-try-catch / require-mkdirsync-try-catch ESLint rules and to avoid crashing the action on I/O failures.

Changes:

Wrapped many fs.*Sync calls (mkdir/read/write/append) in try/catch, generally rethrowing with more descriptive errors and { cause: err }.
Adjusted some “best effort” file appends (outputs/logging paths) to fail soft rather than terminate the action.
Updated the generated release.lock.yml manifest/comment metadata consistent with a recompile.

 const destination = options.path || process.env.GITHUB_WORKSPACE || process.cwd();
- fs.mkdirSync(destination, { recursive: true });
+ try {
+ fs.mkdirSync(destination, { recursive: true });


Good defensive handling — wrapping mkdirSync in try/catch gives a clearer failure message. Consider reusing a shared helper for this pattern across the codebase.

github-actions · 2026-07-17T11:36:18Z

+ try {
+ fs.mkdirSync(destination, { recursive: true });
+ } catch (err) {
+ throw new Error(`Failed to create directory ${destination}: ${String(err)}`, { cause: err });


Nice use of the error cause option to preserve the original stack. The String(err) coercion is fine here for the message text.
