For example, `translate('**a')` is rejected but not `translate('**')`\r\n\r\nRejecting such segments is longstanding **pathlib** behaviour, but it has no precedent in the **glob** module -- `glob.glob(recursive=True)` happily accepts such segments.\r\n\r\n```python\r\n\u003e\u003e\u003e import glob\r\n\u003e\u003e\u003e glob.glob('**.py', recursive=True)\r\n['blah.py']\r\n\u003e\u003e\u003e glob.translate('**.py', recursive=True)\r\nTraceback (most recent call last):\r\n  File \"\u003cstdin\u003e\", line 1, in \u003cmodule\u003e\r\n    glob.translate('**.py', recursive=True)\r\n    ~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^\r\n  File \"/home/barney/projects/cpython/Lib/glob.py\", line 304, in translate\r\n    raise ValueError(\"Invalid pattern: '**' can only be an entire path component\")\r\nValueError: Invalid pattern: '**' can only be an entire path component\r\n```\r\n\r\n`translate()` should treat these segments similar to `glob()`, and leave the pattern validation stuff to pathlib.\r\n\r\n### CPython versions tested on:\r\n\r\nCPython main branch\r\n\r\n### Operating systems tested on:\r\n\r\nLinux\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-116378\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/barneygale","@type":"Person","name":"barneygale"},"datePublished":"2024-03-05T19:34:32.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/116377/cpython/issues/116377"}
