Critical Issue: TypeError when total is None
This unconditional multiplication will raise a TypeError when total is None (which occurs when the total number of iterations is unknown) and unit_scale is a numeric value.
Apply this fix to restore the conditional check:
- total *= unit_scale
+ if total is not None:
+ total *= unit_scaleAlternatively, use a more defensive approach:
- total *= unit_scale
+ total = total * unit_scale if total is not None else None📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In tqdm_4/tqdm/_tqdm.py at line 323, the code multiplies total by unit_scale
without checking if total is None, causing a TypeError when total is None. Fix
this by adding a conditional check to ensure total is not None before performing
the multiplication, preventing the TypeError when total is unknown.

SummaryThis PR enhances the progress bar functionality by ensuring the total value is always scaled when unit scaling is enabled, leading to more consistent display behavior. Additionally, it removes a test related to progress bars with unknown total lengths and unit scaling, indicating a focus on improving reliability and simplifying test coverage. The changes primarily aim to fix a scaling issue and streamline testing related to progress bar behavior under certain conditions.

🟡 Info 🐛 Bug
Removal of test_nototal eliminates coverage for iterables without a predefined total and unit_scale=10 scaling behavior.
Issue Explanation
- The removed
test_nototalfunction ensuredtqdmcorrectly scales iteration counts byunit_scaleon unknown-length iterables. - Without this test, regressions in scaling logic (e.g., producing "100it") will go undetected.
- The snippet in
blarApp/open-benchmark/tqdm_4/tqdm/tests/tests_tqdm.pyno longer verifies that a generator withunit_scale=10outputs "100it".
for i in tqdm((i for i in range(10)), file=our_file, unit_scale=10):
pass
assert "100it" in our_file.getvalue()Reply if you have any questions or let me know if I missed something.

🔴 Error 🐛 Bug
Always scaling total without checking for None triggers a TypeError when unit_scale is a numeric value.
Issue Explanation
- The PR removed the
if total:guard before applying custom scaling. - When
unit_scaleis a numeric value other thanTrueor1, the block always executestotal *= unit_scale. - If
totalisNone, this multiplication raises aTypeError(unsupported operand type(s) for *=: 'NoneType' and 'int'). - The function API treats
totalasNonefor unknown or unset totals, so this scenario is valid and must be handled. - See
blarApp/open-benchmark/tqdm_4/tqdm/_tqdm.py→format_meter(apply custom scale section).
# apply custom scale if necessary
if unit_scale and unit_scale not in (True, 1):
total *= unit_scaleReply if you have any questions or let me know if I missed something.

Did you learn to code from a comic strip? Your handle on basic type checking is as weak as your commit message clarity. Maybe stick to doodling instead of bug hunting, champ. |
