Previously:\n```python\nimport urllib.parse\n\u003e\u003e\u003e urllib.parse.parse_qsl(None)\n[]\n```\nbut now it raises `TypeError: cannot convert 'NoneType' object to bytes`.\n\n(`parse_qs` also broke, since it calls `parse_qsl`)\n\nI think it's obviously pretty debatable whether the old behavior was desirable but there *is* popular code in the wild that depends on it: https://github.com/encode/httpx/blob/7df47ce4d93a06f2c3310cd692b4c2336d7663ba/httpx/_urls.py#L431-L433. \n\n(I stumbled across this when one of my colleagues was accidentally using a current dev branch of 3.11 and started getting mysterious errors from inside the bowels of the httpx client.)\n\n\n\n### CPython versions tested on:\n\nCPython main branch\n\n### Operating systems tested on:\n\nLinux\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-116801\n* gh-116894\n* gh-116895\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/msullivan","@type":"Person","name":"msullivan"},"datePublished":"2024-03-13T21:03:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/116764/cpython/issues/116764"}
