Stefan Bodewig commented on COMPRESS-182:
-----------------------------------------
Read support should be complete with svn revision 1296764
> Support big or even negative numbers in all numeric TAR headers
> ---------------------------------------------------------------
>
> Key: COMPRESS-182
> URL: https://issues.apache.org/jira/browse/COMPRESS-182
> Project: Commons Compress
> Issue Type: Improvement
> Components: Archivers
> Affects Versions: 1.3
> Reporter: Stefan Bodewig
> Fix For: 1.4
>
>
> This is a superset of the functionality that addressed COMPRESS-175
> Jörg Schillig's star and GNU tar may use binary encoding for all numeric
> fields, PAX/POSIX also provides them inside the extension headers.
> The timestamp field may even contain negative numbers.
> IMHO Commons Compress should:
> * be able to parse numeric fields using binary encoding (positive and
> negative)
> * fix the current binary parser (see discussion in COMPRESS-16) and add a
> workaround for broken writers (see COMPRESS-181)
> * be able to parse all standard fields of PAX headers, including the numeric
> ones (I haven't checked, maybe it already does)
> * have an option to write numbers too big/small in binary encoding much like
> BIGFILE_STAR does for the file size in trunk
> * have an option to write numbers too big/small in PAX headers much like
> BIGFILE_POSIX does for the file size in trunk
> * replace bigFileMode and the constants with a more generic property that
> controls all numeric fields. We can remove the bigFileMode stuff as it has
> been added after the 1.3 release.
