Summary: Tar target cannot add file with size > 2GB
Product: Ant
Version: 1.6.5
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Core tasks
AssignedTo: dev@ant.apache.org
ReportedBy: sagar.ipte@gmail.com
Hello:
While adding a file with size > 2GB in tar file using tar task of ant, I am getting exception similar to
�request to write '1024' bytes exceeds size in header of '-2147483648' bytes�
This is thrown at line 238 in TarOutputStream.
I looked into the code, and it seems the issue is related to downcasting of long value to int.
TarEntry reads the file size as long which is correct.
But when TarEntry is added into TarOutputStream (line 138), TarOutputStream downcasts file size value
from long to int
line 167 in TarOutputStream is as follows
this.currSize = (int) entry.getSize();
This is incorrect, this way it will never allow to add file size > than 2147483647 bytes i.e 2GB.
TarOutputStream should maintain entry size as long only.
Thanks
- Sagar
