(strtoimax): Guard declaration with
`#if !HAVE_DECL_STRTOIMAX', rather than just `#ifndef strtoimax'.
The latter fails because some systems (at least rs6000-ibm-aix4.3.3.0)
have their own, conflicting declaration of strtoimax in sys/inttypes.h.
(strtoumax): Likewise, for completeness (it wasn't necessary).
(delay_set_stat): Initialize it to 0.
(set_mode): New arg current_stat_info. Use it (if nonnull) to avoid
taking an extra stat ourselves. All callers changed.
(set_stat): Likewise.
(apply_nonancestor_delayed_set_stat): New arg 'after_symlinks'.
If false, stop when encountering a struct whose 'after_symlinks' member is
true. Otherwise, go through all structures but check them more carefully.
All callers changed.
(extract_archive): When extracting a deferred symlink, if its parent
directory's status needs fixing, then mark the directory as needing
to be fixed after symlinks.
(extract_finish): Fix status of ordinary directories, then apply delayed
symlinks, then fix the status of directories that are ancestors
of delayed symlinks.
struct hack; this avoids wasted space in some cases.
(name_gather): Use strcpy, not memcpy.
for consistency with other code that does similar things.
(read_name_from_file, name_next, name_gather, add_hierarchy_to_namelist):
Avoid quadratic behavior when reallocating buffers.
Check for buffer size overflow.
(addname): Avoid unnecessary clearing of memory.
This fixes a bug reported by Jose Pedro Oliveira.
(dump_file): Use offsetof when computing sizes for
struct hack; this avoids wasted space in some cases.
name size allocation that caused core dumps.
From Jan.Djarv@mbox200.swipnet.se.
(extract_archive): Use strcpy, not memcpy,
for consistency with other code that does similar things.
(UNSIGNED): Renamed from STRTOUXMAX_UNSIGNED.
(verify): New macro.
(INT): Renamed from uintmax_t.
(strtoumax, strtoull, strtoul): Remove.
(strtoimax, strtol, strtoll): New macros.
(strtoimax): Renamed from strtoumax. Interchange signed with unsigned.
Verify sizes at compile-time, not at run-time.
Prefer strtol to strtoll if both work.
(main): Remove.
Require jm_AC_TYPE_UINTMAX_T and jm_AC_TYPE_UNSIGNED_LONG_LONG since they
are needed to parse the include file.
Do not require jm_AC_HEADER_INTTYPES_H; it's obsolete.
Check for inttypes.h.
Simplify logic behind the args to AC_REPLACE.
(<stdlib.h>, <unistd.h>): Include if available.
("xalloc.h"): Include.
(xmalloc, xstrdup, free): Remove decls; no longer needed.
(xgetcwd): Don't assume sizes fit in 'unsigned'.
Check for overflow when path size gets too large.
Simplify failure code.
NO_IGNORE_CASE_OPTION, NO_WILDCARDS_OPTION, NO_WILDCARDS_MATCH_SLASH_OPTION,
WILDCARDS_OPTION, WILDCARDS_MATCH_SLASH_OPTION): New enum values.
(long_options, usage, decode_options): Add support for --anchored,
--ignore-case, --no-anchored, --no-ignore-case, --no-wildcards,
--no-wildcards-match-slash, --recursion, --wildcards,
--wildcards-match-slash.
(decode_options): Implement the new way of interpreting exclude patterns.
(usage): --newer-mtime takes a DATE operand. DATE may be a file name.
(OPTION_STRING, decode_options): Add -I, -y. Currently these options
just print error messages suggesting alternatives.
(add_filtered_exclude): Remove.
However, check for error even for '-' or '+' case.
(print_header): Try parsing uids and gids as unsigned integers first,
and as a uid_t or gid_t only if that fails. This adds support for
listing positive uids and gids that are greater than UID_MAX and
GID_MAX.
Support hard links to symbolic links.
(struct delayed_symlink): Remove 'names' member, replacing it with
'sources' and 'target' member. All uses changed.
(struct string_list): New type.
(delayed_set_stat, extract_archive): Use offsetof when computing sizes
for struct hack; this avoids wasted space in some cases.
(extract_archive): Fix test for absolute pathnames and/or "..".
Use link_error to report errors for links.
Remove redundant trailing '/' at "really_dir", for all uses, not
just before invoking mkdir.
If overwriting old files, do not worry so much about existing directories.
Fix mode computation in the case where the directory exists.
(apply_delayed_symlinks): If we can't make a hard link to a symbolic
link, make a copy of the symbolic link.
