* src/sparse.c: Include <inttostr.h>. (struct tar_sparse_file): offset and dumped_size are off_t, not size_t. optab is now const *. (dump_zeros): Return bool success flag, not off_t. All callers changed. Use a constant-zero buffer rather than clearing a buffer each time. Don't mess up if write fails. (dump_zeros, check_sparse_region): Don't assume off_t is no wider than size_t. (tar_sparse_init): Don't bother clearing a field that is already clear. (zero_block_p): First arg is const *, not *. (clear_block, SPARSES_INIT_COUNT): Remove. (sparse_add_map): First arg is now struct start_stat_info *, not struct tar_sparse_file *. All callers changed. Use x2nrealloc to check for size_t overflow. (parse_scan_file): Cache commonly-used parts of file. Use an auto buffer, not a static one. Don't bother clearing the buffer; not needed. Don't bother clearing items that are already clear. (oldgnu_optab, star_optab, pax_optab): Now const. (sparse_dump_region): Don't bother clearing the buffer before reading into it; just clear the parts that aren't read into. (sparse_dump_file): Clear the whole local variable 'file'. (diff_buffer): Remove; now a local var. (check_sparse_region): Don't bother clearing buffer before reading into it. Don't assume off_t is promoted to long. (oldgnu_get_sparse_info, star_get_sparse_info): Use an auto status, not static. * src/tar.h (struct tar_stat_info): had_trailing_slash is now bool, not int. * src/xheader.c (sparse_offset_coder, sparse_numbytes_coder): Rewrite to avoid cast. (sparse_offset_decoder, sparse_numbytes_decoder): Diagnose excess entries rather than crashing.
