[jira] [Updated] (COMPRESS-16) unable to extract a TAR file that
contains an entry which is 10 GB in size
[ https://issues.apache.org/jira/browse/COMPRESS-16?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
John Kodis updated COMPRESS-16:
-------------------------------
Attachment: 0004-Prefer-octal-over-binary-size-representation.patch
This one-character patch corrects an error in patch 0002.
The expression representing the largest value that an eleven-digit octal number can contain must be forced to a long integer value, as otherwise it overflows the limits of an int and evaluates to zero.

> Key: COMPRESS-16
> URL: https://issues.apache.org/jira/browse/COMPRESS-16
> Project: Commons Compress
> Issue Type: Bug
> Components: Archivers
> Environment: I am using win xp sp3, but this should be platform independent.
> Reporter: Sam Smith
> Attachments: 0001-Accept-GNU-tar-files-with-entries-over-8GB-in-size.patch, 0002-Allow-creating-tar-archives-with-files-over-8GB.patch, 0004-Prefer-octal-over-binary-size-representation.patch, ant-8GB-tar.patch, patch-for-compress.txt

> 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...)?
