> [Python] Correct issues in numpy_to_arrow conversion routines
> -------------------------------------------------------------
>
> Key: ARROW-2380
> URL: https://issues.apache.org/jira/browse/ARROW-2380
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.9.0
> Reporter: Bryan Cutler
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.10.0
>
>
> Following the discussion at [https://github.com/apache/arrow/pull/1689,]
> there are a few issues with conversion of various types to arrow that are
> incorrect or could be improved:
> * PyBytes_GET_SIZE is being casted to the wrong type, for example
> {{const int32_t length = static_cast<int32_t>(PyBytes_GET_SIZE(obj));}}
> * Handle the possibility with the statement
> {{builder->value_data_length() + length > kBinaryMemoryLimit}}
> if length is larger than kBinaryMemoryLimit
> * Look into using common code for binary object conversion to avoid
> duplication, and allow support for bytes and bytearray objects in other
> places than numpy_to_arrow. (possibly put in src/arrow/python/helpers.h)
