755493 - Remote debuggee hangs if breakpoint is hit when debugger connection is interrupted

Status: NEW

(DevTools :: about:debugging, defect, P3)

Description

[Mark Goodwin [:mgoodwin]]

Interrupted debugger sessions can cause debuggee to hang.

STR:
1) Connect debugger to debuggee
2) Set breakpoint in script
3) Introduce some adverse network conditions (wander out of WIFI range, etc)
4) Cause debugee to hit aforementioned breakpoint
5) When this happened to me, the whole of fennec became unresponsive - I forced the process to stop. In hindsight I perhaps should have tried harder to recover to get more information.

I've not been able to reproduce this issue since initial observation

cc'ing lucasr for a little consultation.

This is hard to reproduce and only happens over wifi, afawk.

Has this ever happened since then Mark? There has been no activity no this bug for over 2 years, so I'm leaning towards closing it unless the problem occured recently.
