-------------------------------------
Summary: Tests fail when performed within publicly-protected
directory hierarchies
Key: SYSTEMML-1141
URL: https://issues.apache.org/jira/browse/SYSTEMML-1141
Project: SystemML
Issue Type: Improvement
Components: Test
Environment: Unix-based environments
Reporter: Kevin Bates
Priority: Minor
early 10% (536 of 5789) of the tests run via `mvn verify` fail when any of the
parent directories are protected against searches by others (i.e., do not
include at least read/execute for others bits). This issue can be reproduced
by changing permissions on a parent directory above target/testTemp such that
public access is denied. For example, given a directory hierarchy of
/opt/repos/apache/incubator-systemml, `chmod o-rw /opt/repos` removes from
others the ability to access anything under /opt/repos. This will lead to the
test's failure due to an IOException consisting of a stack caused by frame
indicating the following:
```Caused by: java.io.IOException: Resource
file:/opt/repos/apache/incubator-systemml/target/testTemp/functions/recompile/CSVReadUnknownSizeTest/csv_read_unknown/scratch_space/_p1140_192.168.10.115/TmpOutput6/part-00000
is not publicly accessable and as such cannot be part of the public cache.```
(A simple command to reproduce this is `mvn test -e
-Dtest=CSVReadUnknownSizeTest`.)
In enterprise settings, where a different department is responsible for the
security of resources, it would be helpful if the target/testTemp directory
could be configurable via a runtime parameter. This would allow enterprises to
direct the tests to write to a truly temporary location where the restrictions
against "others" is not a requirement.
