by concatenating strings with "\v" after translation.
(doc): Remove, splitting into:
(doc0, doc1): New constants.
(argp): Don't use doc; just initialize to NULL.
(initialize_argp_doc): New function.
(decode_options): Use it.
carefully. Do not pass arbitrary char values to isspace, as
this has undefined behavior. Likewise for assigning arbitrary
uintmax_t values to other types.
(read_negative_num, read_unsigned_num, read_timespec):
New functions, to check input values a bit more carefuly.
(read_num): Use read_unsigned_num. New arg MAX_VAL;
all callers changed.
(read_incr_db_2): Use these new functions.
Use a consistent diagnostic for unexpected EOF.
(read_directory_file): Do not assign arbitrary uintmax_t value
to int.
(read_timespec, write_directory_file_entry, write_directory_file):
Handle negative time_t values correctly. We don't bother to do
this with pre-2 formats, since presumably the time stamps were
output incorrectly.
vs. GNU format differences.
(mode_to_chars): Treat OLDGNU_FORMAT same as GNU_FORMAT. Fixes bug
reported by TAMUKI Shoichi <tamuki@linet.gr.jp>, which caused
equivalent `tar cf ...' and `tar rf ...' commands to produce
different archives.
(get_max_open_files,closeopen): New functions
(chdir_do): Do not use save_cwd if it was already used more than
max_open_files-4 times to avoid running off the file
descriptors.
argument. All callers changed.
(decode_record): Check for numeric overflow
(xheader_string_end): Return boolean value. Check for possible
numeric overflow
version (1.0) of PAX sparse format.
(pax_sparse_member_p): Fix condition
(pax_dump_header): A dispatcher function
(pax_dump_header_0,pax_dump_header_1): New functions.
(pax_optab): Update
(oldgnu_dump_header): Minor fix: make sure
sparse_header.isextended is set before calling
set_next_block_after
modification times for all archive members during creation.
(struct tar_args): textual_date_option replaced with a linked list
textual_date. All references updated.
(get_date_or_file,report_textual_dates): New functions.
in GNU.sparse.name variable. The name field in the ustar header
now contains generated name (%d/GNUSparseFile.%p/%f), so that
non-pax-aware tars won't extract the file under the original
filename.
files explicitely specified in the command line. Fixes bug
reported by Dat Head on 19 Jun 2006 (descending into mountpoints
with --one-file-system in use)
the --totals option, which specifies a signal upon delivery of which
the statistics must be output.
(main): Call print_total_stats if total_option is set.
(set_start_time): Set volume_start_time and last_stat_time as well
(set_volume_start_time): New function
(compute_duration): Do not call set_start_time, update
last_stat_time instead. Use it in calculation instead of
start_time, which is now set only once, upon startup.
(print_total_written): Removed.
(print_total_stats): New function for printing byte/speed statistics.
(_open_archive): Detect attempts to update compressed archives.
(_gnu_flush_write): Always update prev_written.
(open_archive): Call set_volume_start_time.
number of records between two successive checkpoints (proposed
by Jason Armistead on 2004-06-22).Optional dot starting the
argument means "print dots instead of textual checkpoints".
(tar_help): New function
