gh-159288: Avoid segfault by adding missing recursion checks when walking lazy import chains by brittanyrey · Pull Request #159289 · python/cpython

brittanyrey · 2026-10-13T04:06:55Z

lazy import a.b.c as d nests one placeholder per name component. lazy_import_path() and lazy_import_replay_from() recursed over that chain without a recursion check, so a very long dotted name could overflow the stack.

Add guards to raise a RecursionError instead of failing into a segfault.

Issue: Missing recursion checks building long lazy import alias can segfault #159288

`lazy import a.b.c as d` nests one placeholder per name component. lazy_import_path() and lazy_import_replay_from() recursed over that chain without a recursion check, so a very long dotted name could overflow the C stack. Raise RecursionError instead, as the rest of lazy import resolution does.

FYI, the Android test failure should be fixed by either one of the PRs attached to #159320...
