Remove -I as an alias for -T, for now.
Add @dircategory.
Update copyright. Remove "Published by".
Dates beginning with / or . are taken to be file names.
(usage): Remove -I as an alias for -T>
(OPTION_STRING): Remove -I.
(decode_options): Dates that look like an absolute path name,
or that start with '.', are presumed to be file names whose
dates are taken.
Remove 'I' as an aliase for 'T'.
Update copyright.
> (relativize): New function, with much of old start_header's guts.
Handle filesystem prefixes.
(start_header): Use this new function.
(init_sparsearray): Don't bother to zero out the new array; it's not needed.
(deal_with_sparse): Fix array allocation bug.
(create_archive): Don't assume '/' is the only separator.
(dump_file): Likewise.
Don't worry about leading / in symlink targets.
(time): Remove decl; likewise.
(child_open_for_uncompress): Use new full_write semantics.
(flush_write): Use ISSLASH instead of testing for '/'.
(flush_read): Likewise.
(make_directories): Skip filesystem prefixes.
Don't assume '/' is the only separator.
(extract_sparse_file): Use new full_write semantics.
On write error, return instead of invoking skip_file.
Do not free sparsearray; caller does this now.
(apply_nonancestor_delayed_set_stat): Do not assume '/' is the only
separator.
(extract_archive): Don't assume file name lengths fit in int.
Report what got stripped from member name; it might be more than '/'.
Use new full_write semantics.
Do not pass redundant trailing "/" to mkdir, as POSIX does not allow
mkdir to ignore it.
Do not report mkdir error if old_files_option == KEEP_OLD_FILES.
(long_options): Have getopt set the --no-recursion flag.
(decode_options): Initialize recursion_option to FNM_LEADING_DIR.
Remove case for NO_RECURSE_OPTION.
following changes: Use @sc where appropriate. Document the ranges of
supported times more precisely. Add Eggert to getdate authors.
Document old Latin 12m/12pm tradition. Remove list of alphabetic time
zone names, as it wasn't correct and people shouldn't be relying on it
anyway. Relative items also account for non-DST adjustments. Fix
some misspellings.
(long_options): Now static.
(long_options, usage, decode_options): -j is now short for --bzip2,
and -I is now an alias for -T.
(decode_options, main): argv is not const pointer now.
(decode_options): Invoke prepend_default_options to support TAR_OPTIONS.
In diagnostic, mention the string that was the invalid blocking factor,
tape length, group, owner, or record size.
--delete is no longer incompatible with -f -, undoing 2000-01-07 change.
(main): Invoke extract_finish at end of extraction.
(gnu_list_name): Remove decl.
(struct link): Remove "next" member.
(linklist): Remove.
(start_header): Say "leading `FOO'" rather than "`FOO' prefix" for consistency
with other diagnostics.
(deal_with_sparse): Check for I/O error when closing the file.
(create_archive):
Do not allocate an array of size PATH_MAX, as PATH_MAX might be (size_t) -1.
Instead, allocate an array with the size that's needed.
(hash_link, compare_links): New functions.
(dump_file): Do not exhaust open file descriptors when descending deeply
into a directory, by using savedir rather than opendir/readdir.
Do not zero-fill the name buffer unnecessarily.
Hash the set of links already created, instead of using a linked list.
Fix some bugs in outputting sparse files which caused the sparse tables
to be incorrect.
When a file unexpectedly shrinks, output zeros rather than garbage.
Do not allocate an array of size PATH_MAX, as PATH_MAX might be (size_t) -1.
Instead, allocate an array with the size that's needed.
