| * Test 1b: Strip components extracting archives involving hardlinks. |
| * |
| * This next is a complicated case. d0/l1, d0/d1/l2, and |
| * d0/d1/d2/f1 are all hardlinks to the same file; d0/l1 can't |
| * be extracted with --strip-components=2 and the other two |
| * can. Remember that tar normally stores the first file with |
| * a body and the other as hardlink entries to the first |
| * appearance. So the final result depends on the order in |
| * which these three names get archived. If d0/l1 is first, |
| * none of the three can be restored. If either of the longer |
| * names are first, then the two longer ones can both be |
| * restored. Note that the "tar -cf" command above explicitly |
| * lists d0/l1 before d0/d1. |
| * |
| * It may be worth extending this test to exercise other |
| * archiving orders. |
| * |
| * Of course, this is all totally different for cpio and newc |
| * formats because the hardlink management is different. |
| * TODO: Rename this to test_strip_components_tar and create |
| * parallel tests for cpio and newc formats. |
