Hey, it has json ld scripts:
{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Not all types have \"trashcan\" protection and tp_dealloc can overflow stack","articleBody":"We occasionally fix these kinds of bugs, like GH-102356.  However, the fix by adding the \"trashcan\" macros to the tp_dealloc method only fixes that specific type.  It would be better to have a more generic fix.  A crash due to the C stack overflow leaves the user mystified as to what the problem is and these kinds of bugs could be hard to reproduce (requiring long chains of objects calling tp_dealloc recursively).\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-124716\n* gh-132280\n* gh-133199\n* gh-133434\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/nascheme","@type":"Person","name":"nascheme"},"datePublished":"2024-09-27T22:17:44.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/124715/cpython/issues/124715"}
