Subject [jira] [Resolved] (COMPRESS-16) unable to extract a TAR file that contains an entry which is 10 GB in size
Date Wed, 07 Dec 2011 12:16:40 GMT

     [ https://issues.apache.org/jira/browse/COMPRESS-16?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Stefan Bodewig resolved COMPRESS-16.
------------------------------------

       Resolution: Fixed
    Fix Version/s: 1.4

writing such entris has been split out as COMPRESS-165.

With svn revision 1211405 I have added tests that prove the tar package now understand both
the star/GNU/BSD variant as well as the POSIX/PAX one.

> I made a TAR file which contains a file entry where the file is 10 GB in size.
> When I attempt to extract the file using TarInputStream, it fails with the following
stack trace:
> 	java.io.IOException: unexpected EOF with 24064 bytes unread
> 		at org.apache.commons.compress.archivers.tar.TarInputStream.read(TarInputStream.java:348)
> 		at org.apache.commons.compress.archivers.tar.TarInputStream.copyEntryContents(TarInputStream.java:388)
> So, TarInputStream does not seem to support large (> 8 GB?) files.
> Here is something else to note: I created that TAR file using TarOutputStream , which
did not complain when asked to write a 10 GB file into the TAR file, so I assume that TarOutputStream
has no file size limits?  That, or does it silently create corrupted TAR files (which would
be the worst situation of all...)?
