The new REPL outputs different tracebeck when custom sys.excepthook is used #122478
Description
Activity
And for compile-time errors:
>>> ? File "<unknown>", line 1 ? ^ SyntaxError: invalid syntax >>> import sys; sys.excepthook = lambda *args: sys.__excepthook__(*args) >>> ? Traceback (most recent call last): File "/home/serhiy/py/cpython/Lib/_pyrepl/console.py", line 172, in runsource tree = ast.parse(source) File "/home/serhiy/py/cpython/Lib/ast.py", line 53, in parse return compile(source, filename, mode, flags, _feature_version=feature_version, optimize=optimize) File "<unknown>", line 1 ? ^ SyntaxError: invalid syntax
Seems to be done on purpose in
code.InteractiveInterpreter.showsyntaxerror:
Lines 126 to 132 in bd3d31f
I suppose this could be overridden in _pyrepl to always output with
.write()?- changed the title

Andsys.last_tracebackwas not always correct even with the defaultsys.excepthook.@serhiy-storchaka, can this be closed?

If
sys.systemhookis notsys.__systemhook__, the new REPL outputs the line in the code module in the traceback:>>> xxx Traceback (most recent call last): File "<python-input-0>", line 1, in <module> xxx NameError: name 'xxx' is not defined >>> import sys; sys.excepthook = lambda *args: sys.__excepthook__(*args) >>> xxx Traceback (most recent call last): File "/home/serhiy/py/cpython/Lib/code.py", line 91, in runcode exec(code, self.locals) ~~~~^^^^^^^^^^^^^^^^^^^ File "<python-input-2>", line 1, in <module> xxx NameError: name 'xxx' is not definedLinked PRs
