[3.10] bpo-45183: don't raise an exception when calling zipimport.zipimporter.find_spec() when the zip file is missing and the internal cache has been reset (GH-28435) ( #28438 )
...
This can occur when the zip file gets deleted, you call zipimport.zipimporter.invalidate_cache(), and then try to use zipimport.zipimporter.find_spec() (i.e. you left the zip file path on sys.path).

Release the GIL while performing isatty() system calls on arbitrary

os.device_encoding() and io.TextIOWrapper. By extension,
io.open() in text mode is also affected.

- Make case-swaps half the cost of any other edit
- Refactor Levenshtein code to not use memory allocator, and to bail early on no match.
- Add comments to Levenshtein distance code
- Add test cases for Levenshtein distance behind a debug macro
- Set threshold to `(name_size + item_size + 3) * MOVE_COST / 6`.
- Reasoning: similar to `difflib.SequenceMatcher.ratio()` >= 2/3:
```
"Multiset Jaccard similarity" >= 2/3
matching letters / total letters >= 2/3
(name_size - distance + item_size - distance) / (name_size + item_size) >= 2/3
1 - (2*distance) / (name_size + item_size) >= 2/3
1/3 >= (2*distance) / (name_size + item_size)
(name_size + item_size) / 6 >= distance
With rounding:
(name_size + item_size + 3) // 6 >= distance
