[GitHub] [arrow] pitrou opened a new pull request #10480: ARROW-12993: [Python] Avoid half-initialized FeatherReader object
pitrou opened a new pull request #10480:
URL: https://github.com/apache/arrow/pull/10480
When trying to read an invalid Feather file, the `stackprinter` project
would crash when walking the stack and attempting to print detailed information
about captured local variables.
Specifically, the crash would occur when looking up the `version` attribute
on the half-initialized FeatherReader object.

Looks good.
We have a similar pattern in `_parquet.pyx` ParquetReader, which is used in parquet.ParquetFile, and you can also get this to crash:
```
In [7]: from pyarrow.parquet import ParquetReader
In [8]: ParquetReader()
Out[8]: <pyarrow._parquet.ParquetReader at 0x7f635377b280>
In [9]: reader = ParquetReader()
In [10]: reader.schema_arrow
Segmentation fault (core dumped)
```
