René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"The REPL hangs under no memory on 3.13","articleBody":"# Bug report\n\n### Bug description:\n\nIn the new REPL, failing allocations seem to cause the prompt to get stuck:\n\n```python\n\u003e\u003e\u003e import _testcapi\n\u003e\u003e\u003e _testcapi.set_nomemory(0)  # Now wait forever\n```\n\nI don't expect it to be able to work under no memory, but I do expect it to at least crash gracefully. The basic REPL spits this out before exiting:\n\n```\nobject address  : 0x7f02f532d180\nobject refcount : 3\nobject type     : 0x7f02f5ec7780\nobject type name: MemoryError\nobject repr     : \nlost sys.stderr\n```\n\nIdeally, the new REPL should do something similar. This isn't at all a priority, but something fun for anyone bored and willing to take a stab at it.\n\n### CPython versions tested on:\n\n3.13\n\n### Operating systems tested on:\n\nLinux\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-138491\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/ZeroIntensity","@type":"Person","name":"ZeroIntensity"},"datePublished":"2025-05-17T23:46:05.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/134163/cpython/issues/134163"}
