python - How to get stack trace of exception happening in __del__? -

-

is there easy way stack trace printed exception happens in __del__? in case, there's no __del__ method defined object

exception typeerror: "'nonetype' object not callable" in <bound method interactivesession.__del__ of <tensorflow.python.client.session.interactivesession object @ 0x2867710>> ignored

you'd have detect error manually inside __del__:

def __del__(self):     try:         cleanup()     except exception:         import traceback         traceback.print_exc()          # let error keep propagating.         raise

there's no way configure python exceptions raised __del__. it's direct call pyerr_writeunraisable, no place provide callback, no configuration possible print stack trace, , retrieve exception information afterward.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
