(start_header): Use `member names' to refer to archive member names, not
`archive names'. Warn about `..' in member names.
(finish_sparse_file, dump_file):
Quote arbitrary strings in diagnostics.
(finish_sparse_file, dump_file):
Don't assume that gettext preserves errno.
(dump_file): Don't use `access' to determine whether a directory is readable;
this isn't reliable if tar is setuid. Use `opendir' instead.
Check for readdir and closedir failures.
Don't dump sockets as if they were fifos; just warn and skip.
archive_write_error, archive_read_error, flush_archive, close_archive,
init_volume_number, new_volume):
Don't assume that gettext preserves errno.
(xdup2): Don't report errno if dup returns an unexpected nonnegative value.
(open_archive): Reject multivolume verify attempts a bit earlier.
Rename local variable `access', in case it's defined by system header.
(open_archive, backspace_output): Use `Cannot' uniformly, instead of
`Could not' sometimes and `Cannot' others.
(open_archive, flush_read, flush_archive, close_archive, new_volume):
Quote arbitrary strings in diagnostics.
(read_error): Set archive to STDOUT_FILENO temporarily when writing
archive buffer.
(init_volume_number): Check for input and output errors in volno_file.
(new_volume): Use new fatal_exit function to exit, and new xfork
function to fork.
files. Instead, diagnose them a bit better.
Report that a file changed if its ctime changes; this is more
sensitive than mtime+size, and more accurate.
said should be there, but is absent. It was
probably removed between then and now.
Do not pass meaningless errno to ERROR when reporting that the
file changed as we read it.
Add --disable-largefile.
Remove old NeXT dirent problems, or AIX valloc problems.
Remove old union wait advice, and old %lld advice.
Remove advice about FreeBSD 2.1.7, ISC 4.1mu, Ultrix `make'.
Use chdir_do to change into directory.
Use deref_stat instead of stat.
Use add_avoided_name to mark names to be avoided; the old method of
setting a bit with the name caused all descendants of that name to
be avoided, in some circumstances.
(time): Declare if not defined.
(confirm): Don't read past EOF.
(long_options, usage): Add --no-same-owner, --no-same-permissions.
(main): Use clock_gettime if available.
(name_gather): Use chdir_arg to keep track of arguments to chdir.
(addname): Likewise.
(name_match): Use chdir_do to act on chdir args.
(merge_sort): Moved here from incremen.c.
(compare_names, add_hierarchy_to_namelist, collect_and_sort_names):
Likewise.
(name_expand): Remove.
(name_from_list): Skip fack names.
Use chdir_do to act on chdir args.
(struct avoided_name): New struct.
(avoided_names): New var.
(add_avoided_name, is_avoided_name): New functions.
(base_64_digits): Moved here from create.c.
(base64_map): Use UCHAR_MAX for size, not less-clear (unsigned char) -1.
(read_and): Don't get time from header unless we need it now;
as getting time can cause duplicate diagnostics if bogus.
Remove "Hmm, " from diagnostic.
Use "Skipping to next header" uniformly.
(from_header): Renamed from from_chars. All uses changed.
Allow different forms for unportable 2's complement numbers.
Don't check for extended forms when parsing checksums.
Parse base-256 output.
(gid_from_header): Renamed from gid_from_chars. All uses changed.
(major_from_header): Renamed from major_from_chars. All uses changed.
(minor_from_header): Renamed from minor_from_chars. All uses changed.
(mode_from_header): Renamed from mode_from_chars. All uses changed.
(off_from_header): Renamed from off_from_chars. All uses changed.
(size_from_header): Renamed from size_from_chars. All uses changed.
(time_from_header): Renamed from time_from_chars. All uses changed.
Warn about future timestamps.
(uid_from_header): Renamed from uid_from_chars. All uses changed.
(uintmax_from_header): Renamed from uintmax_from_chars. All uses changed.
(tartime): New function, incorporating isotime.
(isotime): Delete.
(print_header): Use tartime.
(base_64_digits): Move to list.c.
(base_8_digits): Remove.
(to_octal): New function, with some of old contents of to_base.
(to_base): Remove.
(to_base256): New function.
(to_chars): Use base 256, not base 64, for huge values.
(mode_to_chars): Don't use two's complement in GNU format or POSIX format.
(dump_file): Interchange last two arguments. If TOP_LEVEL is negative,
it means we have an incremental dump where we don't know whether this
is a top-level call.
Use deref_stat instead of statx / stat / lstat.
Cast result of alloca.
Check for dates if 0 < top_level, not if listed_incremental_option.
Move multiple-link check after directory check.
Do not dump avoided names.
Dump hard links to symbolic names as links, not as separate symbolic links.
start_header cannot return a null pointer, so don't test for it.
Likewise for find_next_block.
(time): No need to declare.
(now): Remove variable.
(extr_init): Don't initialize `now'.
Increment same_permissions_option and same_owner_option if we_are_root
is nonzero; this supports the new --no-same-owner option.
(set_stat): Use start_time instead of `now'.
(print_total_written): Also print human-readable byte count, and bytes/s.
(open_archive, flush_write): Use start_time, not current time.
(flush_read): Report about garbage bytes ignored at end of archive,
but act on non-garbage bytes (instead of ignoring them).
(new_volume): Use WARN for warnings.
