+
+ * NEWS: New option --atime-preserve=system, which uses O_NOATIME.
+
+ * configure.ac: Prefer AC_CHECK_HEADERS_ONCE to AC_CHECK_HEADERS.
+ Check for stropts.h and sys/filio.h too, for _FIOSATIME.
+ * doc/tar.texi: Change "modification time" to "data modification
+ time", "change time" to "status change time", and "filesystem" to
+ "file system", so that we use terminology consistent with POSIX.
+ Use American spacing rather than French for sentence ends.
+ "non-dependable" -> "undependable".
+ (Option Summary, Attributes): Explain better the pitfalls of the
+ --atime-preserve option, and suggest read-only mounts,loopback
+ mounts, and noatime mounts for older systems.
+ * doc/value.texi (op-atime-preserve-system): Renamed from
+ op-atime-preserver-system to fix a misspelling.
+ * src/common.h (enum atime_preserve): Use lower case for enum values.
+ * src/compare.c: Don't include utimens.h; no longer needed.
+ (diff_file): Use set_file_atime rather than utimens; avoid closing
+ diff_handle until after this, so that we can set the file time stamp
+ via the file descriptor rather than via its name.
+ * src/create.c: Don't include utimens.h; no longer needed.
+ (dump_regular_finish): Remove. All callers now do its work inline.
+ (dump_dir): New arg FD. All callers changed.
+ Use fdsavedir rather than savedir.
+ (unknown_file_error): Arg is a const pointer now.
+ (dump_file0): 2nd arg is a const pointer now.
+ Treat directories more like files, with respect to --atime-preserve.
+ For example, also warn if a directory changes while we are dumping it.
+ Prefer file descriptors to file names when retrieving/setting file
+ attributes; this saves path-resolution time and allows us to avoid
+ changing mtime/ctime on Solaris when restoring atime as root.
+ Use O_DIRECTORY when opening directories, to avoid some race conditions.
+ Do not reset atime if mtime has changed. Report an error if
+ we cannot reset atime.

+
+ First cut at adding support for --atime-preserve=system.
+ * doc/tar.texi (Option Summary): First cut at documenting it.
+ All other uses of --atime-preserve changed to --atime-preserve=replace.
+ * doc/value.texi (op-atime-preserve-replace, op-atime-preserver-system):
+ New.
+ (op-atime-preserve): Mention METHOD.
+ * src/common.h (atime_preserve): New enum.
+ (atime_preserve_option): Now of the enum type rather than bool.
+ All uses changed.
+ * src/compare.c (diff_file): Read with O_NOATIME if asked for.
+ * src/create.c (dump_file0): Read regular and CTG files with O_NOATIME
+ if asked for.
+ * src/tar.c (usage): Mention new usage.
+ (parse_opt): Parse new usage.

+
+ * THANKS: Convert back to UTF-8, sort (using LC_ALL=C on Debian
+ stable), and consistently use tabs rather than spaces.

+ yesterday. Thanks Eric Blake.

+ * po/POTFILES.in: Add rpmatch.c
+ * src/tar.c (confirm): Rewritten using rpmatch.
+ (decode_options): Minor optimizations
+ (main): Call stdopen() to ensure the first three descriptors are
+ open.
+
+ * tests/multiv01.at, tests/multiv02.at, tests/multiv03.at,
+ tests/multiv04.at, tests/sparsemv.at, tests/sparsemvp.at,
+ tests/star/multi-fail.at: Close stdin so that if something fails
+ causing tar to ask for the next volume, it won't hang the
+ testsuite.
+
+ * src/buffer.c (flush_write,flush_read): Change data type.
+ (flush_archive): Compute actual buffer fill level before calling
+ low level function.
+ (close_archive): Call flush_archive again if the first call
+ resulted in partially filled buffer.
+ (try_new_volume): Rewritten handling of initial headers.
+ (add_chunk_header): New function. Write an additional header
+ before the continuation chunk. The purpose of the header is to
+ allow third-party tars to extract the member.
+ (simple_flush_write): Take an argument.
+ (_gnu_flush_write): Correctly handle partially filled buffers.
+ * src/common.h (flush_read,flush_write): Functions, again.
+ (write_extended): Changed declaration
+ (xheader_format_name): New declaration
+ * src/create.c (write_extended): Change type and meaning of

+2005-11-10 Sergey Poznyakoff <gray@gnu.org.ua>
+
+ Fix splitting of sparse files between the volumes.
+
+ * src/buffer.c (try_new_volume): Bugfix. Always check
+ continued_file_name. If it is absent, the volume is out
+ of sync.
+ (add_multi_volume_header): Create GNU.volume.filename keyword in
+ the extended header.
+ * src/sparse.c (sparse_dump_region): Call mv_size_left.
+ (sparse_dump_file): Enclose the loop in mv_begin/mv_end.

+
+ * src/buffer.c: Rewritten in a more modular fashion to provide
+ GNU extensions (multi-volume archives and archive labels) in
+ pax format.
+ NOTICE, that some of the aspects (e.g. splitting the archive
+ on the extended header boundary) are still not solved, others
+ (splitting a sparse file between the volume) require additional
+ testing. Wait for the next commit.

+
+2005-11-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/xheader.c (struct xhdr_tab.coder): Last arg is void const *,

+ * NEWS: Minor language and white space fixes.
+
+ * tests/truncate.at: Create files whose time stamps must fall on

in system.h.
