Alon Amid created ARROW-1659:


 Summary: "stdlib.h: No such file or directory" when 
cross-compiling for RISC-V with GCC 7.2
 Key: ARROW-1659
 URL: https://issues.apache.org/jira/browse/ARROW-1659
 Project: Apache Arrow
  Issue Type: Bug
  Components: C++
 Environment: RISC-V, Cross-compiling for RISC-V Linux with GCC 7.2
Reporter: Alon Amid


I’ve been attempting to cross-compile Arrow for RISC-V.
I was trying to build Arrow with Plasma and Python, but without the compression 
libraries (snappy, brotli, zstd, lz4).
I was getting several errors indicating that stdlib.h is missing. An example 
error is:

ARROW-1535 is resolved so the sdist artifact should be able to be 
installed. If you could help kick the tires with Python 3.7 before Arrow 0.8.0 
is released (end of October / early November) that would be helpful in case we 
missed some detail

[jira] [Created] (ARROW-1658) [Python] Out of bounds dictionary indices causes segfault after converting to pandas

[Wes McKinney (JIRA)]

Wes McKinney created ARROW-1658:
---

 Summary: [Python] Out of bounds dictionary indices causes segfault 
after converting to pandas
 Key: ARROW-1658
 URL: https://issues.apache.org/jira/browse/ARROW-1658
 Project: Apache Arrow
  Issue Type: Bug
  Components: Python
Affects Versions: 0.7.1
Reporter: Wes McKinney
 Fix For: 0.8.0


Minimal reproduction:

{code}
import numpy as np
import pandas as pd
import pyarrow as pa
 
num = 100
arr = pa.DictionaryArray.from_arrays(
np.arange(0, num),
np.array(['a'], np.object),
np.zeros(num, np.bool),
True)

print(arr.to_pandas())
{code}

At no time in the Arrow codebase do we validate that the dictionary indices are 
in bounds. It seems that pandas is overly trusting of the validity of the 
indices. So we should add a method someplace to validate that the dictionary 
non-null indices are not out of bounds (perhaps in 
{{CategoricalBlock::WriteIndices}}).

As an aside: there may be other times when doing analytics on categorical data 
that external data will have out of bounds index values. We should plan for 
these and decide whether to raise an exception or treat them as null

https://github.com/apache/arrow/pull/1188

ARROW-1535: [Python] Enable sdist tarballs to be installed

The tarballs produced by `setup.py sdist` have always been broken. This 
creates a tarball that can be installed assuming that the Arrow/Parquet C++ 
libraries are installed already on the target system.

I wanted to see if I could bundle the `cpp/cmake_modules` files without 
using a symlink but I couldn't figure it out; it might require subclassing the 
sdist cmdclass to make this work. I'm not sure having the symlink is so bad

commit 310af1b7c4664a130cc67047d50f8364e2f6eb33
Author: Wes McKinney 
Date:   2017-10-08T17:51:59Z

Move all cmake files to cpp/cmake_modules, fix up sdist tarball so it can 
be built/installed

Paddy Horan commented on ARROW-1642:


I'm attempting to add the Meson build for windows, but I have a lot to learn so 
I wouldn't expect much from me.  If I get something workable I'll share it with 
you and maybe it saves you some time when you get around to migrating to Meson.

Either way I'll definitely test it on windows / attempt to tweak it to work on 
windows.
