Without this change, if tar tried to extract a file A/B/C, noticed that A/B didn't exist, attempted to mkdir A/B, and the mkdir failed, it did not diagnose the mkdir failure, but simply reported the failure to open A/B/C. This sometimes led to confusion because it wasn't clear what tar was trying to do, in particular that tar tried to mkdir A/B. With this patch, tar issues two diagnostics in this case: one for A/B and the other for A/B/C. Problem reported by Hauke Laging in <http://lists.gnu.org/archive/html/bug-tar/2010-10/msg00020.html>. * gnulib.modules: Remove faccessat. * src/extract.c (make_directories): New arg INTERDIR_MADE. Diagnose mkdir failure. Return 0 on success, nonzero on failure, as opposed to nonzero iff some directory was created. All callers changed. Simplify the code when mkdir fails, by checking whether the desired file exists unless errno==EEXIST: this is more robust. * tests/extrac15.at: New test, to check this. * tests/Makefile.am (TESTSUITE_AT): Add it. * tests/testsuite.at: Include it.
