* src/common.h (name): New field: is_wildcard.
(name_scan): Change protoype.
* src/delete.c: Update calls to name_scan.

only exact matches.

This bug was introduced by the recent lseek-related changes.
* src/delete.c (delete_archive_members):
* src/update.c (update_archive):
Copy the member if acting as a filter, rather than lseeking over
it, which is possible if stdin is a regular file.
* src/list.c (skim_file, skim_member):
* src/sparse.c (sparse_skim_file):
New functions, for copying when a filter.
* src/list.c (skip_file): Remove; replaced with skim_file.
All callers changed.
(skip_member): Reimplement in terms of skim_member.
* src/sparse.c (sparse_skip_file):
Remove; replaced with sparse_skim_file. All callers changed.
* src/update.c (acting_as_filter): New static var.
(update_archive): Set it; this is like delete.c.
* tests/delete01.at (deleting a member after a big one):
* tests/delete02.at (deleting a member from stdin archive):
Also test filter case.
* src/buffer.c, src/delete.c: Do not include system-ioctl.h.
* src/buffer.c (guess_seekable_archive): Remove. This is now done
by get_archive_status, in a different way.
(get_archive_status): New function that gets archive_stat
unless remote, and sets seekable_archive etc.
(_open_archive): Prefer bool for boolean.
(_open_archive, new_volume): Get archive status consistently
by calling get_archive_status in both places.
* src/buffer.c (backspace_output):
* src/compare.c (verify_volume):
* src/delete.c (move_archive):
Let mtioseek worry about mtio.
* src/common.h (archive_stat): New global, replacing ar_dev and
ar_ino. All uses changed.
* src/delete.c (move_archive): Check for integer overflow.
Also report overflow if the archive position would go negative.
* src/system.c: Include system-ioctl.h, for MTIOCTOP etc.
(mtioseek): New function, which also checks for integer overflow.
(sys_save_archive_dev_ino): Remove.
(archive_stat): Now
(sys_get_archive_stat): Also initialize mtioseekable_archive.
(sys_file_is_archive): Don’t return true if the archive is /dev/null
since it’s not a problem in that case.
(sys_detect_dev_null_output): Cache dev_null_stat.
doc: omit MS-DOS mentions in doc
It’s really FAT32 we’re worried about now, not MS-DOS.
And doschk is no longer a GNU program.
With today’s compilers ‘inline’ is typically not needed for
performance (at least the way GNU Tar uses it) and it gets in the
way of portability.
* configure.ac: Omit AC_C_INLINE; no longer needed here.
* lib/attr-xattr.in.h (setxattr, lsetxattr, fsetxattr, getxattr)
(lgetxattr, fgetxattr, listxattr, llistxattr, flistxattr):
* lib/wordsplit.c (skip_delim_internal, skip_delim)
(skip_delim_real, exptab_matches):
* src/delete.c (flush_file):
* src/extract.c (safe_dir_mode):
* src/misc.c (ptr_align):
Now just static, not static inline.
* lib/wordsplit.h (wordsplit_getwords): Remove; no longer used.
* src/common.h (name_more_files): Now COMMON_INLINE, not
extern inline - which is not portable according to C99,
the way we were using it.
* src/common.h (FALLTHROUGH): New macro, for use with gcc
-Wimplicit-fallthrough=5, which is now the default when used with
Gnulib after commit 2017-05-16T16:23:52!eggert@cs.ucla.edu
and with --enable-gcc-warnings
* src/common.h (read_header_mode): New enum.
(read_header): Change type of the 3rd argument.
* src/list.c (read_header): Change type of the 3rd argument.
All callers updated.
* src/buffer.c (try_new_volume): Allow for volumes split at the
extended/ustar header boundary. This is against POSIX specs, but
we must be able to read such archives anyway.
* tests/multiv07.at: New test case.
* tests/Makefile.am: Add multiv07.at
* tests/testsuite.at: Likewise.
* src/compare.c: Update calls to read_header.
* src/delete.c: Likewise.
* src/update.c: Likewise.
* src/buffer.c (match_volume_label): Call set_volume_label.
(check_label_pattern): Get label string
as argument.
(match_volume_label): Handle volume labels stored in
global PAX headers.
* src/common.c (print_header,read_header): Change signature.
(read_header_primitive): Remove prototype.
* src/list.c (recent_global_header): New static.

Save the recent global header.
(volume_label_printed): New static.
(simple_print_header): New function (ex-print_header).
(print_header): Change the signature (all callers updated).
For POSIX formats, print first volume header (if set).
* src/xheader.c (xheader_write_global): Write the data
accumulated in xhdr->stk even if keyword_global_override_list
is empty.
(xheader_read): On unexpected EOF, report error instead of
coredumping.
(XHDR_PROTECTED, XHDR_GLOBAL): New defines.
(struct xhdr_tab): Remove `protected' with `flags'. All uses updated.
(decg): If XHDR_GLOBAL bit is set, call the keyword's decode
method instead of adding it to `kwl'.
* src/compare.c: Update calls to read_header.
* src/create.c: Likewise.
* src/delete.c: Likewise.
* src/update.c: Likewise.
* src/extract.c: Likewise.
(extract_volhdr): Do not print "Reading <label>" statement, because
it is inconsistent: it is not printed if the volume begins with a
member continued from the previous volume.
* tests/label01.at: New testcase.
* tests/label02.at: New testcase.
* tests/Makefile.am, tests/testsuite.at: Add new testcases.
Make sure the files are deleted only if they were succesfully stored
to the archive.
* src/exit.c: New file.
* src/unlink.c: New file.
* src/Makefile.am (tar_SOURCES): Add exit.c and unlink.c.

(fatal_exit_hook): New extern.
* src/create.c (create_archive): Call finish_deferred_unlinks.
(dump_hard_link, dump_file0): Don't actually unlink the file,
queue it to deferred_unlinks instead.
* src/delete.c (records_written): Remove extern: declared in
common.h.
* src/extract.c (extract_archive): Set fatal_exit_hook.
(fatal_exit, xalloc_die): Move to exit.c
* src/system.c (sys_wait_for_child): Exit immediately
if the child dies or exits with a non-zero status.
(sys_child_open_for_compress)
(sys_child_open_for_uncompress): Use set_program_name,
instead of setting program_name directly.
* src/tar.c (main): Use set_program_name,
instead of setting program_name directly.
* tests/Makefile.am (TESTSUITE_AT): Add remfiles01.at
and remfiles02.at.
* tests/testsuite.at: Likewise.
* tests/gzip.at: Reflect the above changes.
