+	* doc/tar.texi: Minor fix
+	* src/tar.c (doc0, doc1, initialize_argp_doc): Removed.  Rely on

+
+	* README: Fix a typo
+
+2006-09-08  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Adjust to latest gnulib.
+	* lib/.cvsignore: Add at-func.c, configmake.h, fchmodat.c,
+	fcntl.h, fcntl_.h, inttypes_.h, lstat.c, lstat.h.
+	* tests/testsuite.at (AT_TAR_MKHIER): Use install-sh -d

+2006-09-08  Sergey Poznyakoff  <gray@gnu.org.ua>
+
+	* src/incremen.c (try_purge_directory): Initialize struct st.  Fix

+	version.
+
+	* bootstrap (intl_files_to_remove): Do not remove m4/inttypes-h.m4
+	and m4/inttypes-pri.m4
+
+2006-08-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* bootstrap: Set XGETTEXT_OPTIONS to flag our printf-format functions,
+	so that translators are warned about strings that are formats but
+	don't look like formats.  This might help prevent core dumps.
+	* configure.ac (AM_GNU_GETTEXT): Upgrade to need-formatstring-macros.
+	Suggested by Eric Blake to avoid problems like
+	<http://lists.gnu.org/archive/html/bug-coreutils/2006-07/msg00087.html>.
+	(AM_GNU_GETTEXT_VERSION): Upgrade from 0.12.1 to 0.15.  The gettext
+	manual says we should use the version number normally expected of
+	maintainers, neither more nor less.
+
+	* bootstrap (get_translations):
+	Don't exclude ky.po; it is working again.
+
+2006-08-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* bootstrap (get_translations):
+	Don't exclude ja.po; it is working again.
+	Don't remove all old .po files if we're merely updating one.
+	* po/.cvsignore: Add Makevars.
+
+2006-08-07  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/tar.c: Work around limitation imposed by gettext 0.15
+	by concatenating strings with "\v" after translation.
+	(doc): Remove, splitting into:
+	(doc0, doc1): New constants.
+	(argp): Don't use doc; just initialize to NULL.
+	(initialize_argp_doc): New function.
+	(decode_options): Use it.
+
+	* bootstrap: Redo po file retrieval to match Bison's method,
+	since the translation project changed its index format.
+	Don't use --assume-autoconf; it's now replaced
+	by looking in configure.ac.
+	(m4/codeset.m4, m4/intdiv.m4, m4/inttypes-pri.m4, m4/isc-posix.m4):
+	(m4/lcmessage.m4, m4/onceonly_2_57.m4, m4/gettext.m4, m4/glibc21.m4):
+	(m4/inttypes_h.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4):
+	(m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4):
+	Don't rename to ..._gl.m4, as this is no longer needed.
+	(m4/geteext.m4): Patch to remove the need for intl/*.
+	Use autopoint manually, then remove the intl files,
+	then undo changes to gnulib files that autoreconf made,
+	and then run aclocal/autoconf/autoheader/automake.
+	This makes our bootstrap procedure closer to Bison's.
+	(po/Makevars): Generate automatically.
+	* configure.ac (AC_PREREQ): Update from 2.59 to 2.60.
+	(gl_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Remove.
+	* gnulib.modules: Add inttypes, stdint.
+	* lib/.cvsignore: Add close-stream.c, close-stream.h,
+	stdint.h, stdint_.h.
+	* po/Makefile: Remove; now automatically generated.
+
+	* src/incremen.c (read_incr_db_01): Check input strings more
+	carefully.  Do not pass arbitrary char values to isspace, as
+	this has undefined behavior.  Likewise for assigning arbitrary
+	uintmax_t values to other types.
+	(read_negative_num, read_unsigned_num, read_timespec):
+	New functions, to check input values a bit more carefuly.
+	(read_num): Use read_unsigned_num.  New arg MAX_VAL;
+	all callers changed.
+	(read_incr_db_2): Use these new functions.
+	Use a consistent diagnostic for unexpected EOF.
+	(read_directory_file): Do not assign arbitrary uintmax_t value
+	to int.
+	(read_timespec, write_directory_file_entry, write_directory_file):
+	Handle negative time_t values correctly.  We don't bother to do
+	this with pre-2 formats, since presumably the time stamps were
+	output incorrectly.
+
+	* src/tar.c (doc): Don't use \v in an argument to gettext;
+	gettext 0.15 rejects this.
+
+2006-07-24  Sergey Poznyakoff  <gray@gnu.org.ua>
+
+	* src/tar.c (decode_options): Do not require -L with -M -Hpax.
+	It could be needed in future, but currently it is not.
+	* src/create.c (to_chars_subst): Update comment regarding OLDGNU
+	vs. GNU format differences.
+	(mode_to_chars): Treat OLDGNU_FORMAT same as GNU_FORMAT. Fixes bug
+	reported by TAMUKI Shoichi <tamuki@linet.gr.jp>, which caused
+	equivalent `tar cf ...' and `tar rf ...' commands to produce
+	different archives.
+
+	* tests/append02.at: New test case
+	* tests/Makefile.am, tests/testsuite.at: Add append02.at
+
+2006-07-20  Paul Eggert  <eggert@cs.ucla.edu>

+	it with --assume-autoconf='latest-stable'.
+
+2006-07-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Adjust to recent gnulib changes.
+	* lib/.cvsignore: Remove atexit.c, exit.c, getndelim2.c, getndelim2.h,
+	pathmax.h, paxconvert.c, paxerror.h, xstrdup.c.
+	Add inttypes.h, mktime.c, wcwidth.h, xstrndup.c, xstrndup.h.
+	* src/create.c (start_header): Adjust to API change to mode_adjust.

+The notion of sparse file, and the ways of handling it from the point
+of view of @GNUTAR{} user have been described in detail in
+@ref{sparse}.  This chapter describes the internal format @GNUTAR{}
+uses to store such files.
+
+The support for sparse files in @GNUTAR{} has a long history.  The
+earliest version featuring this support that I was able to find was 1.09,
+released in November, 1990.  The format introduced back then is called
+@dfn{old GNU} sparse format and in spite of the fact that its design
+contained many flaws, it was the only format @GNUTAR{} supported 
+until version 1.14 (May, 2004), which introduced initial support for
+sparse archives in @acronym{PAX} archives (@pxref{posix}).  This
+format was not free from design flows, either and it was subsequently
+improved in versions 1.15.2 (November, 2005) and 1.15.92 (June,
+2006). 
+
+In addition to GNU sparse format, @GNUTAR{} is able to read and
+extract sparse files archived by @command{star}.
+
+The following subsections describe each format in detail.
+

+@cindex sparse formats, Old GNU
+@cindex Old GNU sparse format
+The format introduced some time around 1990 (v. 1.09).  It was
+designed on top of standard @code{ustar} headers in such an
+unfortunate way that some of its fields overwrote fields required by
+POSIX.
+
+An old GNU sparse header is designated by type @samp{S}
+(@code{GNUTYPE_SPARSE}) and has the following layout:
+
+@multitable @columnfractions 0.10 0.10 0.20 0.20 0.40
+@headitem Offset @tab Size @tab Name   @tab Data type   @tab Contents

+@item        345 @tab  12  @tab atime  @tab Number      @tab @code{atime} of the file.
+@item        357 @tab  12  @tab ctime  @tab Number      @tab @code{ctime} of the file .
+@item        369 @tab  12  @tab offset @tab Number      @tab For
+multivolume archives: the offset of the start of this volume.
+@item        381 @tab   4  @tab        @tab N/A         @tab Not used.
+@item        385 @tab   1  @tab        @tab N/A         @tab Not used.
+@item        386 @tab  96  @tab sp     @tab @code{sparse_header} @tab (4 entries) File map.
+@item        482 @tab   1  @tab isextended @tab Bool        @tab @code{1} if an
+extension sparse header follows, @code{0} otherwise.
+@item        483 @tab  12  @tab realsize @tab Number      @tab Real size of the file.
+@end multitable
+
+Each of @code{sparse_header} object at offset 386 describes a single
+data chunk. It has the following structure: 
+
+@multitable @columnfractions 0.10 0.10 0.20 0.60
+@headitem Offset @tab Size @tab Data type   @tab Contents
+@item          0 @tab   12 @tab Number      @tab Offset of the
+beginning of the chunk.
+@item         12 @tab   12 @tab Number      @tab Size of the chunk.
+@end multitable
+
+If the member contains more than four chunks, the @code{isextended}
+field of the header has the value @code{1} and the main header is
+followed by one or more @dfn{extension headers}.  Each such header has
+the following structure:
+
+@multitable @columnfractions 0.10 0.10 0.20 0.20 0.40
+@headitem Offset @tab Size @tab Name   @tab Data type   @tab Contents

+(21 entires) File map.
+@item        504 @tab    1 @tab isextended @tab Bool    @tab @code{1} if an
+extension sparse header follows, or @code{0} otherwise.
+@end multitable
+
+A header with @code{isextended=0} ends the map.

+@vrindex GNU.sparse.numbytes, extended header variable
+Size of the data block
+@end table
+
+The latter two variables repeat for each data block, so the overall
+structure is like this:
+
+@smallexample
+@group
+GNU.sparse.size=@var{size}      
+GNU.sparse.numblocks=@var{numblocks} 
+repeat @var{numblocks} times
+  GNU.sparse.offset=@var{offset}    
+  GNU.sparse.numbytes=@var{numbytes}  
+end repeat
+@end group
+@end smallexample
+
+This format presented the following two problems:
+
+@enumerate 1
+@item
+Whereas the POSIX specification allows a variable to appear multiple
+times in a header, it requires that only the last occurrence be
+meaningful.  Thus, multiple occurrences of @code{GNU.sparse.offset} and
+@code{GNU.sparse.numbytes} are conflicting with the POSIX specs.
+
+@item
+Attempting to extract such archives using a third-party @command{tar}s
+results in extraction of sparse files in @emph{compressed form}.  If
+the @command{tar} implementation in question does not support POSIX
+format, it will also extract a file containing extension header
+attributes.  This file can be used to expand the file to its original
+state.  However, posix-aware @command{tar}s will usually ignore the
+unknown variables, which makes restoring the file more
+difficult.  @xref{extracting sparse v.0.x, Extraction of sparse
+members in v.0.0 format}, for the detailed description of how to
+restore such members using non-GNU @command{tar}s.
+@end enumerate
+
+@cindex sparse formats, v.0.1
+@GNUTAR{} 1.15.2 introduced sparse format version @code{0.1}, which
+attempted to solve these problems.  As its predecessor, this format
+stores sparse map in the extended POSIX header.  It retains
+@code{GNU.sparse.size} and @code{GNU.sparse.numblocks} variables, but
+instead of @code{GNU.sparse.offset}/@code{GNU.sparse.numbytes} pairs
+it uses a single variable:
+
+@table @code
+@item GNU.sparse.map
+@vrindex GNU.sparse.map, extended header variable
+Map of non-null data chunks.  It is a string consisting of
+comma-separated values "@var{offset},@var{size}[,@var{offset-1},@var{size-1}...]" 
+@end table
+
+To address the 2nd problem, the @code{name} field in @code{ustar}
+is replaced with a special name, constructed using the following pattern:
+
+@smallexample
+%d/GNUSparseFile.%p/%f
+@end smallexample
+
+@vrindex GNU.sparse.name, extended header variable
+The real name of the sparse file is stored in the variable
+@code{GNU.sparse.name}.  Thus, those @command{tar} implementations
+that are not aware of GNU extensions will at least extract the files
+into separate directories, giving the user a possibility to expand it
+afterwards.  @xref{extracting sparse v.0.x, Extraction of sparse
+members in v.0.1 format}, for the detailed description of how to
+restore such members using non-GNU @command{tar}s.
+
+The resulting @code{GNU.sparse.map} string can be @emph{very} long.
+Although POSIX does not impose any limit on the length of a @code{x}
+header variable, this possibly can confuse some tars.
+
+@node PAX 1
+@appendixsubsec PAX Format, Version 1.0
+
+@cindex sparse formats, v.1.0
+The version @code{1.0} of sparse format was introduced with @GNUTAR{}
+1.15.92.  Its main objective was to make the resulting file
+extractable with little effort even by non-posix aware @command{tar}
+implementations.  Starting from this version, the extended header
+preceding a sparse member always contains the following variables that
+identify the format being used:
+
+@table @code
+@item GNU.sparse.major
+@vrindex GNU.sparse.major, extended header variable
+Major version
+
+@item GNU.sparse.minor
+@vrindex GNU.sparse.minor, extended header variable
+Minor version
+@end table
+
+The @code{name} field in @code{ustar} header contains a special name,
+constructed using the following pattern:
+
+@smallexample
+%d/GNUSparseFile.%p/%f
+@end smallexample
+
+@vrindex GNU.sparse.name, extended header variable, in v.1.0
+@vrindex GNU.sparse.realsize, extended header variable
+The real name of the sparse file is stored in the variable
+@code{GNU.sparse.name}.  The real size of the file is stored in the
+variable @code{GNU.sparse.realsize}.
+
+The sparse map itself is stored in the file data block, preceding the actual
+file data.  It consists of a series of octal numbers of arbitrary length, delimited 
+by newlines. The map is padded with nulls to the nearest block boundary.
+
+The first number gives the number of entries in the map. Following are map entries,
+each one consisting of two numbers giving the offset and size of the
+data block it describes.
+
+The format is designed in such a way that non-posix aware tars and tars not
+supporting @code{GNU.sparse.*} keywords will extract each sparse file
+in its condensed form with the file map prepended and will place it
+into a separate directory.  Then, using a simple program it would be
+possible to expand the file to its original form even without @GNUTAR{}.
+@xref{Sparse Recovery}, for the detailed information on how to extract
+sparse members without @GNUTAR{}.

   POSIX requires the latest occurrence of the variable to override all
   previous occurrences.
-     
-   To avoid this incompatibility new keyword GNU.sparse.map was introduced
-   in tar 1.15.2. Some people might still need the 1.14 way of handling
-   sparse files for the compatibility reasons: it can be achieved by
-   specifying `--pax-option delete=GNU.sparse.map' in the command line.
+   
+   To avoid this incompatibility two following versions were introduced.

-   See FIXME-1.14-1.15.1-1.20, below.
+   * 0.1
+
+   Used by tar 1.15.2 -- 1.15.91 (alpha releases).
+   
+   The sparse file map is stored in
+   x header:
+
+   GNU.sparse.size      Real size of the stored file
+   GNU.sparse.numblocks Number of blocks in the sparse map
+   GNU.sparse.map       Map of non-null data chunks. A string consisting
+                       of comma-separated values "offset,size[,offset,size]..."
+
+   The resulting GNU.sparse.map string can be *very* long. While POSIX does not
+   impose any limit on the length of a x header variable, this can confuse some
+   tars.
+
+   * 1.0
+
+   Starting from this version, the exact sparse format version is specified
+   explicitely in the header using the following variables:
+
+   GNU.sparse.major     Major version 
+   GNU.sparse.minor     Minor version
+
+   X header keeps the following variables:
+   
+   GNU.sparse.name      Real file name of the sparse file
+   GNU.sparse.realsize  Real size of the stored file (corresponds to the old
+                        GNU.sparse.size variable)
+
+   The name field of the ustar header is constructed using the pattern
+   "%d/GNUSparseFile.%p/%f".
+   
+   The sparse map itself is stored in the file data block, preceding the actual
+   file data. It consists of a series of octal numbers of arbitrary length,
+   delimited by newlines. The map is padded with nulls to the nearest block
+   boundary.
+
+   The first number gives the number of entries in the map. Following are map
+   entries, each one consisting of two numbers giving the offset and size of
+   the data block it describes.
+
+   The format is designed in such a way that non-posix aware tars and tars not
+   supporting GNU.sparse.* keywords will extract each sparse file in its
+   condensed form with the file map attached and will place it into a separate
+   directory. Then, using a simple program it would be possible to expand the
+   file to its original form even without GNU tar.
+
+   Bu default, v.1.0 archives are created. To use other formats,
+   --sparse-version option is provided. Additionally, v.0.0 can be obtained
+   by deleting GNU.sparse.map from 0.1 format: --sparse-version 0.1
+   --pax-option delete=GNU.sparse.map

Paul Eggert	01b6fb98bf	* bootstrap: Set XGETTEXT_OPTIONS to flag our printf-format functions, so that translators are warned about strings that are formats but don't look like formats. This might help prevent core dumps. * configure.ac (AM_GNU_GETTEXT): Upgrade to need-formatstring-macros. Suggested by Eric Blake to avoid problems like <http://lists.gnu.org/archive/html/bug-coreutils/2006-07/msg00087.html>. (AM_GNU_GETTEXT_VERSION): Upgrade from 0.12.1 to 0.15. The gettext manual says we should use the version number normally expected of maintainers, neither more nor less.	2006-08-11 21:39:36 +00:00

Paul Eggert	0680ad4d42	* src/tar.c: Work around limitation imposed by gettext 0.15 by concatenating strings with "\v" after translation. (doc): Remove, splitting into: (doc0, doc1): New constants. (argp): Don't use doc; just initialize to NULL. (initialize_argp_doc): New function. (decode_options): Use it.	2006-08-08 05:28:32 +00:00
Paul Eggert	1942370acd	Fix typo: remove po/tar.html.	2006-08-07 22:58:12 +00:00
Paul Eggert	94de7c4c77	* bootstrap: Redo po file retrieval to match Bison's method, since the translation project changed its index format. Don't use --assume-autoconf; it's now replaced by looking in configure.ac. (m4/codeset.m4, m4/intdiv.m4, m4/inttypes-pri.m4, m4/isc-posix.m4): (m4/lcmessage.m4, m4/onceonly_2_57.m4, m4/gettext.m4, m4/glibc21.m4): (m4/inttypes_h.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4): (m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4): Don't rename to ..._gl.m4, as this is no longer needed. (m4/geteext.m4): Patch to remove the need for intl/. Use autopoint manually, then remove the intl files, then undo changes to gnulib files that autoreconf made, and then run aclocal/autoconf/autoheader/automake. This makes our bootstrap procedure closer to Bison's. (po/Makevars): Generate automatically. configure.ac (AC_PREREQ): Update from 2.59 to 2.60. (gl_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Remove. * gnulib.modules: Add inttypes, stdint. * lib/.cvsignore: Add close-stream.c, close-stream.h, stdint.h, stdint_.h. * po/Makefile: Remove; now automatically generated.	2006-08-07 22:57:25 +00:00
Paul Eggert	05805868f2	(read_incr_db_01): Check input strings more carefully. Do not pass arbitrary char values to isspace, as this has undefined behavior. Likewise for assigning arbitrary uintmax_t values to other types. (read_negative_num, read_unsigned_num, read_timespec): New functions, to check input values a bit more carefuly. (read_num): Use read_unsigned_num. New arg MAX_VAL; all callers changed. (read_incr_db_2): Use these new functions. Use a consistent diagnostic for unexpected EOF. (read_directory_file): Do not assign arbitrary uintmax_t value to int. (read_timespec, write_directory_file_entry, write_directory_file): Handle negative time_t values correctly. We don't bother to do this with pre-2 formats, since presumably the time stamps were output incorrectly.	2006-08-07 21:29:27 +00:00
Paul Eggert	57aa98047e	gettext 0.15 rejects this.	2006-08-07 21:12:21 +00:00

Sergey Poznyakoff	f4e4adea80	(to_chars_subst): Update comment regarding OLDGNU vs. GNU format differences. (mode_to_chars): Treat OLDGNU_FORMAT same as GNU_FORMAT. Fixes bug reported by TAMUKI Shoichi <tamuki@linet.gr.jp>, which caused equivalent `tar cf ...' and `tar rf ...' commands to produce different archives.	2006-07-24 09:13:21 +00:00
Sergey Poznyakoff	7110641821	(decode_options): Do not require -L with -M -Hpax. It could be needed in future, but currently it is not.	2006-07-24 09:12:55 +00:00
Paul Eggert	fce454b5ca	* bootstrap: Adjust to today's change to gnulib-tool by invoking it with --assume-autoconf='latest-stable'.	2006-07-20 16:57:31 +00:00
Paul Eggert	8ad985ea6c	Adjust to recent gnulib changes. * lib/.cvsignore: Remove atexit.c, exit.c, getndelim2.c, getndelim2.h, pathmax.h, paxconvert.c, paxerror.h, xstrdup.c. Add inttypes.h, mktime.c, wcwidth.h, xstrndup.c, xstrndup.h. * src/create.c (start_header): Adjust to API change to mode_adjust.	2006-07-17 05:47:26 +00:00
