It required a lot of effort, because this category is big, so after doing 2/3 of the work I put it off for later. Certain circumstances prevented me from completing it. But now I found time to return to it.\r\n\r\nIn the meantime, other people have done some of this work (moving parts of the `_testcapi.c` to a separate files, adding coverage for more C API functions), and some of the legacy C API has been removed. Therefore, it took more than a week to arrange the code, fix conflicts, remove outdated tests and write remaining tests. But some errors may still remain, be careful.\r\n\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-99594\n* gh-99651\n* gh-99868\n* gh-104728\n* gh-106595\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/serhiy-storchaka","@type":"Person","name":"serhiy-storchaka"},"datePublished":"2022-11-19T11:33:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/99593/cpython/issues/99593"}
