* unzip: ignore chmod errorsNatanael Copa2012-05-281-1/+1
| | | | | | | | This makes unzip to FAT filesystems not exit with error. This is similar to how the "normal" unzip works. Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* update seamless uncompression codeDenys Vlasenko2012-03-061-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes "tar tf hello_world.txz" work without adding special-casing for ".txz" extension.

* Improve unzip's handling of stream ZIP filesDan Fandrich2010-06-181-4/+9
| | | | | | | | | | | Search harder for the ZIP magic numbers at the end of a file by checking 16 KiB from the end instead of just 1 KiB. ZIP files with long comments (such as certain cryptographically signed files) or those sitting in a wrapper could have more than 1 KiB of data after the magic numbers, so they couldn't be read.
