This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. Confirmed ... I'm able to create such archives with gzip - tar is not able to recognize archive header in those files - if the only one file is present in the .tar.gz archive . The same is for e.g. midnight commander archive viewer. Adding gzip maintainer to cc to check whether the issue is in tar or gzip. Easily reproducible by gzip -c <file> | tar tz . Additionally - by `gzip -c <several files> >archive.tar.gz` I was easily able to create archive which shows: gzip -lv archive.tar.gz method crc date time compressed uncompressed ratio uncompressed_name defla 73a9f53f May 11 15:16 22210 14256 -55.6% archive.tar (archive.tar file is probably corrupted as I can't extract it). Probably notabug in tar, but misuse of gzip/some suffix magic ... sorry for confusing comment#3/#4 - maybe the same or similar confusion like archive creator. Most probably NOTABUG - as if you gunzip the archive, you have .tar which is still gzip-compressed, so it looks like double gzip compression and only suffix magic. To be sure it would be necessary to know how the archive was created. |
