Web Error handling and exception catching

Project description


This software is not actively maintained. Simple bugfixes and other patches will be accepted, and released.


WebError provides WSGI middleware for the debugging and handling of errors inside of WSGI applications.


There are two primary WSGI middleware components:


This middleware should be used for production deployed applications and is used to track extra information regarding errors that occur. These error entries can additionally be emailed to a given email address using the error_email option. Example usage:

from weberror.errormiddleware import make_error_middleware
app = make_error_middleware(app, global_conf)


This middleware is used to help debug errors in wsgi applications during development and should not be used in production. Example usage:

from weberror.evalexception import make_eval_exception
app = make_eval_exception(app, global_conf)
