[jira] [Updated] (ARROW-7442) [Ruby]Specifying column type as time
causes segmentation fault
[ https://issues.apache.org/jira/browse/ARROW-7442?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kitaiti Makoto updated ARROW-7442:
----------------------------------
Description:
Hi, I might find a bug.
When we specify column type as time via Arrow::Table.load's column_types named argument, it causes segmentation fault:
I think Ruby's any extension libraries should not cause SEGV.
Script to reproduce this issue(timedata.rb):
{code:java}
require "arrow"
CSV_FILE = File.join(__dir__, "timedata.csv")
table = Arrow::Table.load(CSV_FILE, column_types: [["datetime", :time]]{code}
Sample CSV file(timedata.csv) is:
{code:java}
id,datetime,name
1,2019-12-19T18:30,
,,
{code}
Result:
{code:java}
% ruby -v ./timedata.rb

Hi, I might find a bug.
When we specify column type as time via Arrow::Table.load's column_types named argument, it causes segmentation fault:
I think Ruby's any extension libraries should not cause SEGV.
{code:java}
require "arrow"
CSV_FILE = File.join(__dir__, "timedata.csv")
table = Arrow::Table.load(CSV_FILE, column_types: [["datetime", :time]]{code}
{code:java}
% ruby -v ./timedata.rb

> Key: ARROW-7442
> URL: https://issues.apache.org/jira/browse/ARROW-7442
> Project: Apache Arrow
> Issue Type: Bug
> Components: Ruby
> Affects Versions: 0.15.1
> Environment: * Ubuntu 10.04 on Windows Subsystem for Linux
> * Windows 10 Enterprise
> * Ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-linux]

> Priority: Major

> Hi, I might find a bug.
> When we specify column type as time via Arrow::Table.load's column_types named argument, it causes segmentation fault:
> I think Ruby's any extension libraries should not cause SEGV.
> Script to reproduce this issue(timedata.rb):
> {code:java}
> require "arrow"
> CSV_FILE = File.join(__dir__, "timedata.csv")
> table = Arrow::Table.load(CSV_FILE, column_types: [["datetime", :time]]{code}
> Sample CSV file(timedata.csv) is:
> {code:java}
> id,datetime,name
> 1,2019-12-19T18:30,
> ,,
> {code}
> Result:
> {code:java}
> % ruby -v ./timedata.rb
