Description

Fixes #60837

Errors thrown within the onReadyCallback passed to setupHistory() were being silently discarded when called from async contexts (event listeners and catch handlers).

This was a regression introduced in #58225.

Changes

• Wrapped callback invocations in try-catch blocks at two locations in lib/internal/repl/history.js:

  1. Line 324-328: Inside the 'flushHistory' event listener
  2. Line 352-356: Inside the kHandleHistoryInitError method

• Use process.nextTick(() => { throw err; }) to properly propagate errors to the event loop, ensuring callback errors are not silently swallowed.

Root Cause Analysis

In ReplHistory.initialize(), when onReadyCallback is invoked:

• Inside event listeners (line 324)
• Inside catch handlers (line 352)

Any errors thrown by the callback were being caught by the surrounding async context and silently discarded. The fix ensures these errors are re-thrown via process.nextTick to properly surface them.

Testing

Verified that callback errors are now properly propagated and cause uncaught exception handlers to fire as expected.
