What it is and what it does
zExceptions is a library of exception classes and utilities designed for the Zope web framework ecosystem. It provides a standardized set of HTTP status exceptions, authorization and redirect exceptions, and helper functions for exception handling in Zope applications. The package is built on top of zope.interface, zope.publisher, and zope.security, making it a foundational component for Zope-based projects that need consistent exception semantics across the framework.
The library has been actively maintained since its first release and currently supports modern Python versions (3.10–3.14). It is primarily useful for developers building Zope applications or integrating with the Zope ecosystem, where standardized exception handling and HTTP status code representation are expected. The package has no known security vulnerabilities and is classified as mature.
Use it for
- Raising HTTP status exceptions in Zope web applications with consistent response handling.
- Handling authorization failures with the Unauthorized exception class in Zope-based access control.
- Converting non-HTTP exceptions to HTTP exceptions for consistent error responses in Zope.
- Setting custom response headers and bodies on exceptions within Zope request/response cycles.
