(See https://github.com/ericsnowcurrently/multi-core-python/wiki/3-CPython's-Runtime#cpythons-run-time-data.)\r\n\r\nThe state of each interpreter (`PyInterpreterState`) encapsulates the data which is unique to that interpreter and isolated from other interpreters.  That isolation is important for the proper operation of multiple interpreters in a process, and will be critical for a per-interpreter GIL, AKA PEP 684 (assuming it gets approved).  There are still a number of gaps in isolation which we will address here.\r\n\r\nThe deficiencies may be categorized by the following:\r\n\r\n* shared runtime state (`_PyRuntimeState`) conceptually better suited to each interpreter\r\n* shared runtime state currently protected by the GIL\r\n* shared global variables that shouldn't be shared\r\n* shared global variables currently protected by the GIL\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-100262\n* gh-101941\n* gh-102331\n* gh-102333\n* gh-102334\n* gh-102335\n* gh-102338\n* gh-102339\n* gh-102682\n* gh-102858\n* gh-102925\n* gh-102938\n* gh-103063\n* gh-103084\n* gh-103150\n* gh-103315\n* gh-103460\n* gh-103794\n* gh-105470\n* gh-105514\n* gh-105515\n* gh-105516\n* gh-105517\n* gh-105525\n* gh-105532\n* gh-105619\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/ericsnowcurrently","@type":"Person","name":"ericsnowcurrently"},"datePublished":"2022-12-14T00:09:00.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":18},"url":"https://github.com/100227/cpython/issues/100227"}
