------------------------------------
Summary: TarArchiveEntry: getDirectoryEntries not working
Key: COMPRESS-366
URL: https://issues.apache.org/jira/browse/COMPRESS-366
Project: Commons Compress
Issue Type: Bug
Components: Archivers
Affects Versions: 1.12
Environment: Eclipse 4.6, Linux 64 Bit
Reporter: Casi Colada
Priority: Minor
TarArchiveEntry.getDirectoryEntries() always returns an empty array. This is
because entry.getFile() returns null for a directory entry.
Let folder.tar be a Tar Archive which contains a folder, and that folder
contains a file. Consider the following snippet:
----
import java.io.FileInputStream;
import org.apache.commons.compress.archivers.tar.*;
public class GetDirectoryEntriesBug {
public static void main(String[] args) throws Exception {
TarArchiveInputStream tais = new TarArchiveInputStream(new
FileInputStream("folder.tar"));
for(TarArchiveEntry entry; (entry = tais.getNextTarEntry()) !=
null; ) {
System.out.println("Name: " + entry.getName() + ",
isDirectory: " + entry.isDirectory() + ", getDirectoryEntries().length: " +
entry.getDirectoryEntries().length);
}
tais.close();
}
}
----
Output:
Name: folder/file, isDirectory: false, getDirectoryEntries().length: 0
Name: folder/, isDirectory: true, getDirectoryEntries().length: 0
I expected that, for "folder/", getDirectoryEntries() will not return an empty
array.
