[issue42548] debugger stops at breakpoint of `pass` that is not actually reached

[Andy S]

Andy S  added the comment:

Then maybe those RMs (for 3.9 and 3.10) should decide on their own? That should 
mean the bug should be reopened for them to get assigned to.

[issue42548] debugger stops at breakpoint of `pass` that is not actually reached

[Andy S]

Andy S  added the comment:

Can reproduce this on 3.9. Is the fact 3.9 is in `bugfix` status enough to 
backport any fixing changes from 3.11 (if that's true and the bug was fixed)?

[issue42548] debugger stops at breakpoint of `pass` that is not actually reached

[Andy S]

New submission from Andy S :

The python (3.6) doc states 
(https://docs.python.org/3/reference/simple_stmts.html#the-pass-statement):

pass is a null operation...

So since this is still an operation one could expect that it can be used as an 
op to breakpoint on while debugging some scripts.

Nevertheless:

$ pdb3.7 ./debug_bug.py 
> /...play/debug_bug.py(1)()
-> a = None
(Pdb) list
  1  -> a = None
  2  
  3  
  4 def fun():
  5 b = False
  6 if a is None:
  7 b = True
  8 pass
  9 else:
 10 pass
 11  
(Pdb) 
 12  
 13 fun()
 14 pass
[EOF]
(Pdb) b 10
Breakpoint 1 at /...play/debug_bug.py:10
(Pdb) run
Restarting ./debug_bug.py with arguments:
./debug_bug.py
> /...play/debug_bug.py(1)()
-> a = None
(Pdb) continue
> /...play/debug_bug.py(10)fun()
-> pass
(Pdb) bt
  /usr/lib/python3.7/bdb.py(585)run()
-> exec(cmd, globals, locals)
  (1)()
  /...play/debug_bug.py(13)()
-> fun()
> /...play/debug_bug.py(10)fun()
-> pass
(Pdb) p b
True
(Pdb)
