Instead, that block creates generator expressions like `docs = (dict(zip(headers, row)) for row in reader)`\r\n\r\nThese iterables are consumed later, outside the `with file_progress()` block, which consumes the underlying iterator, and in turn updates the progress bar.\r\n\r\nThis means that the `ProgressBar.__exit__` method gets called before the last time the `ProgressBar.update` method gets called. The result is that the code to make the cursor invisible (inside the `update()` method) is called after the cleanup code to make it visible (in the `__exit__` method).\r\n\r\nThe fix is to move consumption of the `docs` iterators within the progress bar block. (\r\n\r\n(An additional fix, to make ProgressBar more robust against this kind of misuse, would to make it refusing to update after its `__exit__` method had been called, just like files cannot be `read()` after they are closed. That requires a in the click library).\r\n\r\nNote that Github diff obscures the simplicity of this diff, it's just indenting a block of code.\r\n\r\n\r\n\r\n----\n:books: Documentation preview :books:: https://sqlite-utils--598.org.readthedocs.build/en/598/\n\r\n", "repo": {"value": 140912432, "label": "sqlite-utils"}, "type": "pull", "active_lock_reason": null, "performed_via_github_app": null, "reactions": "{\"url\": \"https://api.github.com/repos/simonw/sqlite-utils/issues/598/reactions\", \"total_count\": 1, \"+1\": 0, \"-1\": 0, \"laugh\": 0, \"hooray\": 0, \"confused\": 0, \"heart\": 0, \"rocket\": 1, \"eyes\": 0}", "draft": 0, "state_reason": null}
