c3fa22fc80 Read POSIX multivolume archives split at the header boundary.
* 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.

166b7c7d02 Fix listing of volume labels (in particular in PAX archives).
* 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.
(list_archive): Always print volume labels.
(read_header_primitive): Remove.
(read_header): Change the signature (all callers updated)
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.

* src/misc.c (struct namebuf): New structure.

checks. This is taken care of in update_archive.

to produce full file names.
* src/names.c (nametail): Remove extra level of
indirection. All uses updated.
(avoided_name_table, add_avoided_name)
(is_avoided_name): Remove.
* src/update.c (update_archive): Change algorithm.
Instead of adding unmodified files to the avoided_name
table, create namelist so that it contains only
modified files.

51aee274e8 Fix handling of files removed during incremental dumps.
Changes to src/create.c and src/incremen.c are partially
based on patch from Alexander Peslyak <solar at openwall.com>.

The new testcases require paxutils commit f653a2b or later.

* src/common.h (struct name): New member `cmdline'.
(dump_file): Change type of the 2nd argument to bool.
(file_removed_diag, dir_removed_diag): New prototypes.
(addname): New argument `cmdline'.
(name_from_list): Change return value.
* src/create.c (dump_dir0, dump_dir): top_level is bool.
(create_archive): Update calls to name_from_list.
Take advantage of the name->cmdline to set top_level argument
during incremental backups.
(dump_file0): top_level is bool.
Do not bail out if a no-top-level file disappears during incremental
backup, use file_removed_diag instead.
(dump_filed): top_level is bool.
* src/incremen.c (update_parent_directory): Silently ignore
ENOENT.  It should have already been reported elsewhere.
(scan_directory): Use dir_removed_diag to report missing directories.
* src/misc.c (file_removed_diag, dir_removed_diag): New functions.
* src/names.c (name_gather): Set ->cmdname.
(addname): Likewise. All uses updated.
(name_from_list): Return struct name const *. All uses updated.

* tests/filerem01.at: New testcase.
* tests/filerem02.at: New testcase.
* tests/Makefile.am, tests/testsuite.at: Add filerem01.at, filerem02.at
* tests/grow.at, test/truncate.at: Use new syntax for genfile --run.

* NEWS: Update.
* doc/tar.texi: Minor fix.

current archive format.
* src/common.h (tar_timespec_cmp): New declaration.

3209329337 Don't filter time stamps through the resolution supported
by struct stat; keep them to full nanosecond resolution.
This affects behavior only on older hosts or file systems
that have lower-resolution time stamps.
* src/common.h (OLDER_STAT_TIME): Parenthesize arg.
(OLDER_TAR_STAT_TIME): New macro.
(code_timespec): New function.
(BILLION, LOG10_BILLION, TIMESPEC_STRSIZE_BOUND): New constants.
* src/compare.c (diff_file): Use full time stamp resolution.
* src/create.c (start_header, dump_file0): Likewise.
(start_header, dump_file0): Adjust to new structure layout.
(dump_regular_finish): Simplify by using timespec_cmp.
* src/extract.c (struct delayed_set_stat): Don't store stat info
that we don't need, to save space.  All uses changed.
(struct delayed_set_stat, struct delayed_link, file_newer_p):
(create_placeholder_file, extract_link, apply_delayed_links):
Use full time stamp resolution.
(check_time): Use code_timespec rather than rolling our own code.
(set_stat, delay_set_stat): Arg now points to tar_stat_info to
avoid losing time information.  All callers changed.
* src/list.c (read_and, decode_header, print_heaeder):
Use full time stamp resolution.
* src/misc.c (code_timespec): New function.
* src/tar.h (struct tar_stat_info): Record atime, mtime, ctime
separately, for benefit of hosts with lower resolution.
* src/update.c (update_archive): Use full time stamp resolution.
* src/xheader.c (code_time): Use new code_timespec function
to simplify code.
(atime_coder, atime_decoder, ctime_coder, ctime_decoder):
(mtime_coder, mtime_decoder): Use full time stamp resolution.

Report time stamps to full resolution in environment.
Report memory allocation failures rather than ignoring them.
* src/system.c (time_to_env): New function.
(oct_to_env, str_to_env, chr_to_env): Report memory allocation failures.
(stat_to_env): Report full resolution in time stamps.

e6d8e9279f (update_archive): Remove call to name_expand; had no effect.
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.
