[issue6498] Py_Main() does not return on SystemExit

Mark Hammond added the comment: Isn't the only problem here that the docs refer to SystemError instead of SystemExit - eg 'raise SystemError("foo")' in an interactive session doesn't terminate the process at all (and I don't believe it should) whereas SystemExit obviously does. -- no

Rogi added the comment: @mhammond Wat did you say? I tried to fix this issue at teh time with no success. It would require too much rewriting. I have not found any way to handle exceptions at C level using this function up to teh present time. --

Mark Hammond added the comment: Note the quoted documentation in comment 1, the paragraph "Note that if an otherwise unhandled SystemError ..." I don't think that paragraph is correct - SystemError doesn't seem to terminate Py_Main - but if you replace "SystemError" with "SystemExit", that pa

Eric Frederich added the comment: So there is a disconnect. You can either change the documentation to match the behavior or you can change the code to match the documentation. I would prefer to leave the documentation alone and make Py_Main return rather than exit on sys.exit. That's just

Mark Hammond added the comment: @Rogi - you seem to have a problem with your keyboard - the 'h' and 'e' keys seem to have been swapped. The docs are wrong regardless - I don't think anyone would suggest the behaviour match the docs regarding SystemError - having Py_Main return on SystemError

Rogi added the comment: @mhammond After reading your post again I noticed you talk about SystemError and not SystemExit. In fact, Py_Main() should not return on SystemError. Teh documentation states "if the interpreter exits due to an exception", which implies teh interpreter _exiting_,

Mark Hammond added the comment: @Rogi - you might like to re-read my responses a couple more times: * I refer to SystemError as the docs *you quoted* refer to SystemError. Therefore, we should *not* make the implementation match the docs - the docs would be wrong *even if* we change Python t
