Bug#1004870: python-xarray: autopkgtest regression on s390x

[Rajendra Kharat1]

Hi Graham,

We have identified the RCA of the problem that reported last month related to python-xarray. The problem was in pandas library where handling of big endian arch was not available in below file.


pandas/_libs/tslibs/conversion.pyx +225



By the time we identify this issue and fix it, from the pandas repo owners have already fixed that and with latest pandas package we are not getting that error.



Could you please upgrade the both pandas and xarray and confirm once.



Thanks,

Rajendra

Hi Graham,

Could you please share the steps to reproduce the issue.
As when I am trying to reproduce I ran into different problem of segmentation fault.
Below are the steps that I followed.
1. Install python3-xarray on debian on s390x arch.
2. cd /usr/lib/python3/dist-packages/xarray
3. python3 -m pytest tests/ -vvv

For now I am debugging the segmentation fault, however just wanted to validate the steps to reproduce.

Thanks,
Rajendra

Hi Rajendra

Thanks for taking a look!

Unfortunately, that cannot be the solution, as that commit is already
present in the version of pandas in the archive [1].

Regards
Graham
