CpioArchiveEntry ignores invalid modes
--------------------------------------
Key: COMPRESS-55
URL: https://issues.apache.org/jira/browse/COMPRESS-55
Project: Commons Compress
Issue Type: Bug
Reporter: Sebb
CpioArchiveEntry has the following code:
{code}
default:
// FIXME: testCpioUnarchive fails if I change the line to
// actually throw the excpetion
new IllegalArgumentException("Unknown mode (full mode: " + mode
+ ", masked mode: " + (mode & S_IFMT));
}
{code}
As the comment says, rejecting invalid modes causes test failures.
These appear to be caused by the code
{bq} this.cpioEntry.setMode(0);
in the method CpioArchiveOutputStream.finish()
Is a mode of 0 allowed? If so, then setMode needs to allow it, otherwise the
method call needs to change to something else.
