Print traceback without an exception

openby mzakharocscopened 2019-04-02updated 2019-05-14

Hello, in CPython, there is a way to print a traceback outside of an exception, through traceback.print_stack() function. What would it take to add similar functionality to micropython?

'module' object has no attribute 'exc_info'

sys.exc_info doesn't seem to be implemented yet, but sys.print_exception was already exist.
I think it won't be too difficult to open the exc_info interface based on the implementation of sys.print_exception, but it will be useful for logging and troubleshooting.

some module like traceback and logging need this interface to work normally.
Hope you can adopt my suggestion.
Tks!

Issue #4667 requests implementing traceback.print_stack() to print the current call stack without an active exception. Issue #7464 requests implementing sys.exc_info() which is needed for traceback and logging modules to work properly. While both issues relate to exception handling and the traceback module, they address different specific features: #4667 wants stack printing without an exception, while #7464 wants exception info retrieval. The implementation of sys.exc_info() (#7464) would be a prerequisite for some traceback functionality but doesn't directly solve the request in #4667 for print_stack() without an exception. They are connected topics in the same code area but address different capabilities.

Suggested action

Keep both issues open as they request different features. The maintainer may want to consider implementing both as they are complementary debugging/introspection capabilities.
