uexceptions

This page describes how gopy implements exceptions. The design follows CPython page-for-page. For the upstream reference see cpython/exceptions.

Source map​

The Go code lives at the module root in flat packages.

PackageRole
(TBD)Mirror of the matching CPython source file.

Differences from CPython​

Notes on places where gopy intentionally diverges from CPython.
  • Go's GC owns memory. There is no Py_INCREF / Py_DECREF.
  • Bytecode layout, opcodes, and error messages match CPython 3.14 byte for byte.
  • Goroutines back the C threads model where it shows through.

Status​

See the status table for which functions in this subsystem are ported and which are pending.

Cross reference​

  • CPython companion: cpython/exceptions.
  • Spec: see ~/notes/Spec/1700/ for the port spec covering this subsystem.
