| 1926729132 | PR_kwDOCGYnMM5b7Z_y | 598 | Fixed issue #433 - CLI eats cursor | 62745 | closed | 0 | 2 | 2023-10-04T18:06:58Z | 2023-11-04T00:46:55Z | 2023-11-04T00:40:30Z | CONTRIBUTOR | simonw/sqlite-utils/pulls/598 | The issue is that underlying iterator is not fully consumed within the body of the `with file_progress()` block. Instead, that block creates generator expressions like `docs = (dict(zip(headers, row)) for row in reader)` These iterables are consumed later, outside the `with file_progress()` block, which consumes the underlying iterator, and in turn updates the progress bar. This 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). The fix is to move consumption of the `docs` iterators within the progress bar block. ( (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). Note that Github diff obscures the simplicity of this diff, it's just indenting a block of code. <!-- readthedocs-preview sqlite-utils start --> ---- :books: Documentation preview :books:: https://sqlite-utils--598.org.readthedocs.build/en/598/ <!-- readthedocs-preview sqlite-utils end --> | 140912432 | pull | {
