The implementer must either:\n\n- Read the entire entry and write afterwards (which is memory-intensive and inefficient for large files), or\n- Use a temporary file for buffered copying.\n\nBoth approaches are more complex and less performant, due to the need to decompress and recompress data.\n\nIt would be much more performant and friendly by implementing a `copy()` method, using the similar internal buffered copying technique introduced by #134627 with the internal `_ZipRepacker`.\n\nThis also opens the door to support an efficient `move()` operation, composed of `copy()`, `remove()`, and optionally `repack()`.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-151825\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/danny0838","@type":"Person","name":"danny0838"},"datePublished":"2026-06-21T00:24:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/151824/cpython/issues/151824"}
