| /* |
| * Background: There are two written standards for the tar file format. |
| * The first is the POSIX 1988 "ustar" format, the second is the 2001 |
| * "pax extended" format that builds on the "ustar" format by adding |
| * support for generic additional attributes. Buried in the details |
| * is one frustrating incompatibility: The 1988 standard says that |
| * tar readers MUST ignore the size field on hardlink entries; the |
| * 2001 standard says that tar readers MUST obey the size field on |
| * hardlink entries. libarchive tries to navigate this particular |
| * minefield by using auto-detect logic to guess whether it should |
| * or should not obey the size field. |
| * |
| * This test tries to probe the boundaries of such handling; the test |
| * archives here were adapted from real archives created by real |
| * tar implementations that are (as of early 2008) apparently still |
| * in use. |
