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.
