Walkthrough

Fixed a pointer iteration bug in iOS device handling where range-loop variables were all referencing the same memory location. Updated to index-based iteration, ensuring each device address points to its unique slice element.

Changes

Cohort / File(s) Summary
iOS device pointer fix
devices/common.go
Corrected iteration logic to append distinct device pointers by iterating via index instead of range-looping over slice variable

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

  • Pointer aliasing issue: Verify the fix correctly prevents all pointers from referencing the same loop variable
  • Test coverage: Confirm existing tests validate that distinct devices maintain separate pointer addresses

Poem

🐰 Range loops beware, a subtle snare,
Loop variables shared beyond compare!
Index by index, each device stands tall,
With pointers distinct—no more sharing at all! ✨

120-122: Perfect! The verification is complete. Let me review the findings:

Verification Results:

  1. Git History Confirms Fix: Commit 340f82e with message "fix: multiple real devices would override each other's pointers" confirms this was the intended change.

  2. Current Code is Correct: The code at lines 120-122 uses index-based iteration (for i := range iosDevices) and correctly appends &iosDevices[i], taking the address of the actual slice element, not a loop variable.

  3. No Similar Anti-patterns Found: Searched for all append calls with address-of operators throughout the codebase. Results show:

    • Line 121: &iosDevices[i] ✓ (correct - actual element)
    • Line 137: &SimulatorDevice{...} ✓ (correct - new struct)
    • Line 148, 425: &AndroidDevice{...} ✓ (correct - new structs)

    None exhibit the anti-pattern of taking the address of a loop variable.

  4. Fix is Complete and Isolated: The fix is properly contained to just the iOS device iteration section.


Excellent fix for a critical pointer aliasing bug.

The change from value-based ranging to index-based iteration correctly addresses the Go loop variable capture issue. Previously, all pointers would reference the same memory location (the loop variable), causing all iOS devices to point to the last device in the slice. A thorough search of the codebase confirms no similar anti-patterns exist elsewhere.
