---------------------------------------
jcrist opened a new pull request #1517: ARROW-2036: [Python] Support standard
IOBase methods on NativeFile
URL: https://github.com/apache/arrow/pull/1517
Adds support for most common file methods, adding enough to use
`io.TextIOWrapper`.
Added attribtes/methods:
- `closed` attribute
- `readable`, `writable`, `seekable` methods
- `read1` alias for `read` to support `TextIOWrapper` on python 2
- No-op `flush` method
Also refactored the cython internals a bit, adding default settings for
`is_readable` and `is_writable`, which makes subclasses not need to set
them in all places.
Also renamed `is_writeable` to `is_writable` for common spelling with
the standard python method `writable`.

> If `NativeFile` supported most/all of the standard IOBase methods
> ([https://docs.python.org/3/library/io.html#io.IOBase),] then it'd be easier
> to use arrow files with other python libraries. Would at least be nice to
> support enough operations to use `io.TextIOWrapper`.
