.Sh DESCRIPTION
.Nm
creates and manipulates streaming archive files.
This implementation can extract from tar, pax, cpio, zip, jar, ar,
and ISO 9660 cdrom images and can create tar, pax, cpio, ar,
and shar archives.
.Pp
The first synopsis form shows a
.Dq bundled
option word.
This usage is provided for compatibility with historical implementations.
See COMPATIBILITY below for details.
.Pp
The other synopsis forms show the preferred usage.
The first option to
.Nm
is a mode indicator from the following list:
.Bl -tag -compact -width indent
.It Fl c
Create a new archive containing the specified items.
.It Fl r
Like
.Fl c ,
but new entries are appended to the archive.
Note that this only works on uncompressed archives stored in regular files.
The
.Fl f
option is required.
.It Fl t
List archive contents to stdout.
.It Fl u
Like
.Fl r ,
but new entries are added only if they have a modification date
newer than the corresponding entry in the archive.
Note that this only works on uncompressed archives stored in regular files.
The
.Fl f
option is required.
.It Fl x
Extract to disk from the archive.
If a file with the same name appears more than once in the archive,
each copy will be extracted, with later copies overwriting (replacing)
earlier copies.
.El
.Pp
In
.Fl c ,
.Fl r ,
or
.Fl u
mode, each specified file or directory is added to the
archive in the order specified on the command line.
By default, the contents of each directory are also archived.
.Pp
In extract or list mode, the entire command line
is read and parsed before the archive is opened.
The pathnames or patterns on the command line indicate
which items in the archive should be processed.
Patterns are shell-style globbing patterns as
documented in
.Xr tcsh 1 .
.Sh OPTIONS
Unless specifically stated otherwise, options are applicable in
all operating modes.
.Bl -tag -width indent
.It Cm @ Ns Pa archive
(c and r mode only)
The specified archive is opened and the entries
in it will be appended to the current archive.
As a simple example,
.Dl Nm Fl c Fl f Pa - Pa newfile Cm @ Ns Pa original.tar
writes a new archive to standard output containing a file
.Pa newfile
and all of the entries from
.Pa original.tar .
In contrast,
.Dl Nm Fl c Fl f Pa - Pa newfile Pa original.tar
creates a new archive with only two entries.
Similarly,
.Dl Nm Fl czf Pa - Fl -format Cm pax Cm @ Ns Pa -
reads an archive from standard input (whose format will be determined
automatically) and converts it into a gzip-compressed
pax-format archive on stdout.
In this way,
.Nm
can be used to convert archives from one format to another.
.It Fl b Ar blocksize
Specify the block size, in 512-byte records, for tape drive I/O.
As a rule, this argument is only needed when reading from or writing
to tape drives, and usually not even then as the default block size of
20 records (10240 bytes) is very common.
.It Fl C Ar directory
In c and r mode, this changes the directory before adding
the following files.
In x mode, change directories after opening the archive
but before extracting entries from the archive.
.It Fl -check-links
(c and r modes only)
Issue a warning message unless all links to each file are archived.
.It Fl -chroot
(x mode only)
.Fn chroot
to the current directory after processing any
.Fl C
options and before extracting any files.
.It Fl -exclude Ar pattern
Do not process files or directories that match the
specified pattern.
Note that exclusions take precedence over patterns or filenames
specified on the command line.
.It Fl -format Ar format
(c, r, u mode only)
Use the specified format for the created archive.
Supported formats include
.Dq cpio ,
.Dq pax ,
.Dq shar ,
and
.Dq ustar .
Other formats may also be supported; see
.Xr libarchive-formats 5
for more information about currently-supported formats.
In r and u modes, when extending an existing archive, the format specified
here must be compatible with the format of the existing archive on disk.
.It Fl f Ar file
Read the archive from or write the archive to the specified file.
The filename can be
.Pa -
for standard input or standard output.
If not specified, the default tape device will be used.
(On
.Fx ,
the default tape device is
.Pa /dev/sa0 . )
.It Fl H
(c and r mode only)
Symbolic links named on the command line will be followed; the
target of the link will be archived, not the link itself.
.It Fl h
(c and r mode only)
Synonym for
.Fl L .
.It Fl I
Synonym for
.Fl T .
.It Fl -include Ar pattern
Process only files or directories that match the specified pattern.
Note that exclusions specified with
.Fl -exclude
take precedence over inclusions.
If no inclusions are explicitly specified, all entries are processed by
default.
The
.Fl -include
option is especially useful when filtering archives.
For example, the command
.Dl Nm Fl c Fl f Pa new.tar Fl -include='*foo*' Cm @ Ns Pa old.tgz
creates a new archive
.Pa new.tar
containing only the entries from
.Pa old.tgz
containing the string
.Sq foo .
.It Fl j
(c mode only)
Compress the resulting archive with
.Xr bzip2 1 .
In extract or list modes, this option is ignored.
Note that, unlike other
.Nm tar
implementations, this implementation recognizes bzip2 compression
automatically when reading archives.
.It Fl k
(x mode only)
Do not overwrite existing files.
In particular, if a file appears more than once in an archive,
later copies will not overwrite earlier copies.
.It Fl -keep-newer-files
(x mode only)
Do not overwrite existing files that are newer than the
versions appearing in the archive being extracted.
.It Fl L
(c and r mode only)
All symbolic links will be followed.
Normally, symbolic links are archived as such.
With this option, the target of the link will be archived instead.
.It Fl l
This is a synonym for the
.Fl -check-links
option.
.It Fl m
(x mode only)
Do not extract modification time.
By default, the modification time is set to the time stored in the archive.
.It Fl n
(c, r, u modes only)
Do not recursively archive the contents of directories.
.It Fl -newer Ar date
(c, r, u modes only)
Only include files and directories newer than the specified date.
This compares ctime entries.
.It Fl -newer-mtime Ar date
(c, r, u modes only)
Like
.Fl -newer ,
except it compares mtime entries instead of ctime entries.
.It Fl -newer-than Pa file
(c, r, u modes only)
Only include files and directories newer than the specified file.
This compares ctime entries.
.It Fl -newer-mtime-than Pa file
(c, r, u modes only)
Like
.Fl -newer-than ,
except it compares mtime entries instead of ctime entries.
.It Fl -nodump
(c and r modes only)
Honor the nodump file flag by skipping this file.
.It Fl -null
(use with
.Fl I ,
.Fl T ,
or
.Fl X )
Filenames or patterns are separated by null characters,
not by newlines.
This is often used to read filenames output by the
.Fl print0
option to
.Xr find 1 .
.It Fl -numeric-owner
(x mode only)
Ignore symbolic user and group names when restoring archives to disk,
only numeric uid and gid values will be obeyed.
.It Fl O
(x, t modes only)
In extract (-x) mode, files will be written to standard out rather than
being extracted to disk.
In list (-t) mode, the file listing will be written to stderr rather than
the usual stdout.
.It Fl o
(x mode)
Use the user and group of the user running the program rather
than those specified in the archive.
Note that this has no significance unless
.Fl p
is specified, and the program is being run by the root user.
In this case, the file modes and flags from
the archive will be restored, but ACLs or owner information in
the archive will be discarded.
.It Fl o
(c, r, u mode)
A synonym for
.Fl -format Ar ustar
.It Fl -one-file-system
(c, r, and u modes)
Do not cross mount points.
.It Fl -options Ar options
Select optional behaviors for particular modules.
The argument is a text string containing comma-separated
keywords and values.
These are passed to the modules that handle particular
formats to control how those formats will behave.
Each option has one of the following forms:
.Bl -tag -compact -width indent
.It Ar key=value
The key will be set to the specified value in every module that supports it.
Modules that do not support this key will ignore it.
.It Ar key
The key will be enabled in every module that supports it.
This is equivalent to
.Ar key Ns Cm =1 .
.It Ar !key
The key will be disabled in every module that supports it.
.It Ar module:key=value , Ar module:key , Ar module:!key
As above, but the corresponding key and value will be provided
only to modules whose name matches
.Ar module .
.El
The currently supported modules and keys are:
.Bl -tag -compact -width indent
.It Cm iso9660:joliet
Support Joliet extensions.
This is enabled by default, use
.Cm !joliet
or
.Cm iso9660:!joliet
to disable.
.It Cm iso9660:rockridge
Support Rock Ridge extensions.
This is enabled by default, use
.Cm !rockridge
or
.Cm iso9660:!rockridge
to disable.
.It Cm gzip:compression-level
A decimal integer from 0 to 9 specifying the gzip compression level.
.It Cm xz:compression-level
A decimal integer from 0 to 9 specifying the xz compression level.
.It Cm mtree: Ns Ar keyword
The mtree writer module allows you to specify which mtree keywords
will be included in the output.
Supported keywords include:
.Cm cksum , Cm device , Cm flags , Cm gid , Cm gname , Cm indent ,
.Cm link , Cm md5 , Cm mode , Cm nlink , Cm rmd160 , Cm sha1 , Cm sha256 ,
.Cm sha384 , Cm sha512 , Cm size , Cm time , Cm uid , Cm uname .
The default is equivalent to:
.Dq device, flags, gid, gname, link, mode, nlink, size, time, type, uid, uname .
.It Cm mtree:all
Enables all of the above keywords.
You can also use
.Cm mtree:!all
to disable all keywords.
.It Cm mtree:use-set
Enable generation of
.Cm /set
lines in the output.
.It Cm mtree:indent
Produce human-readable output by indenting options and splitting lines
to fit into 80 columns.
.It Cm zip:compression Ns = Ns Ar type
Use
.Ar type
as compression method.
Supported values are store (uncompressed) and deflate (gzip algorithm).
.El
If a provided option is not supported by any module, that
is a fatal error.
.It Fl P
Preserve pathnames.
By default, absolute pathnames (those that begin with a /
character) have the leading slash removed both when creating archives
and extracting from them.
Also,
.Nm
will refuse to extract archive entries whose pathnames contain
.Pa ..
or whose target directory would be altered by a symlink.
This option suppresses these behaviors.
.It Fl p
(x mode only)
Preserve file permissions.
Attempt to restore the full permissions, including owner, file modes, file
flags and ACLs, if available, for each item extracted from the archive.
By default, newly-created files are owned by the user running
.Nm ,
the file mode is restored for newly-created regular files, and
all other types of entries receive default permissions.
If
.Nm
is being run by root, the default is to restore the owner unless the
.Fl o
option is also specified.
.It Fl q ( Fl -fast-read )
(x and t mode only)
Extract or list only the first archive entry that matches each pattern
or filename operand.
Exit as soon as each specified pattern or filename has been matched.
By default, the archive is always read to the very end, since
there can be multiple entries with the same name and, by convention,
later entries overwrite earlier entries.
This option is provided as a performance optimization.
.It Fl S
(x mode only)
Extract files as sparse files.
For every block on disk, check first if it contains only NULL bytes and seek
over it otherwise.
This works similiar to the conv=sparse option of dd.
.It Fl -strip-components Ar count
(x mode only)
Remove the specified number of leading path elements.
Pathnames with fewer elements will be silently skipped.
Note that the pathname is edited after checking inclusion/exclusion patterns
but before security checks.
.It Fl s Ar pattern
Modify file or archive member names according to
.Pa pattern .
The pattern has the format
.Ar /old/new/ Ns Op gps
where
.Ar old
is a basic regular expression,
.Ar new
is the replacement string of the matched part,
and the optional trailing letters modify
how the replacement is handled.
If
.Ar old
is not matched, the pattern is skipped.
Within
.Ar new ,
~ is substituted with the match, \1 to \9 with the content of
the corresponding captured group.
The optional trailing g specifies that matching should continue
after the matched part and stopped on the first unmatched pattern.
The optional trailing s specifies that the pattern applies to the value
of symbolic links.
The optional trailing p specifies that after a successful substitution
the original path name and the new path name should be printed to
standard error.
.It Fl T Ar filename
In x or t mode,
.Nm
will read the list of names to be extracted from
.Pa filename .
In c mode,
.Nm
will read names to be archived from
.Pa filename .
The special name
.Dq -C
on a line by itself will cause the current directory to be changed to
the directory specified on the following line.
Names are terminated by newlines unless
.Fl -null
is specified.
Note that
.Fl -null
also disables the special handling of lines containing
.Dq -C .
.It Fl U
(x mode only)
Unlink files before creating them.
Without this option,
.Nm
overwrites existing files, which preserves existing hardlinks.
With this option, existing hardlinks will be broken, as will any
symlink that would affect the location of an extracted file.
.It Fl -use-compress-program Ar program
Pipe the input (in x or t mode) or the output (in c mode) through
.Pa program
instead of using the builtin compression support.
.It Fl v
Produce verbose output.
In create and extract modes,
.Nm
will list each file name as it is read from or written to
the archive.
In list mode,
.Nm
will produce output similar to that of
.Xr ls 1 .
Additional
.Fl v
options will provide additional detail.
.It Fl -version
Print version of
.Nm
and
.Nm libarchive ,
and exit.
.It Fl w
Ask for confirmation for every action.
.It Fl X Ar filename
Read a list of exclusion patterns from the specified file.
See
.Fl -exclude
for more information about the handling of exclusions.
.It Fl y
(c mode only)
Compress the resulting archive with
.Xr bzip2 1 .
In extract or list modes, this option is ignored.
Note that, unlike other
.Nm tar
implementations, this implementation recognizes bzip2 compression
automatically when reading archives.
.It Fl z
(c mode only)
Compress the resulting archive with
.Xr gzip 1 .
In extract or list modes, this option is ignored.
Note that, unlike other
.Nm tar
implementations, this implementation recognizes gzip compression
automatically when reading archives.
.It Fl Z
(c mode only)
Compress the resulting archive with
.Xr compress 1 .
In extract or list modes, this option is ignored.
Note that, unlike other
.Nm tar
implementations, this implementation recognizes compress compression
automatically when reading archives.
.El
.Sh ENVIRONMENT
The following environment variables affect the execution of
.Nm :
.Bl -tag -width ".Ev BLOCKSIZE"
.It Ev LANG
The locale to use.
See
.Xr environ 7
for more information.
.It Ev TAPE
The default tape device.
The
.Fl f
option overrides this.
.It Ev TZ
The timezone to use when displaying dates.
See
.Xr environ 7
for more information.
.El
.Sh FILES
.Bl -tag -width ".Ev BLOCKSIZE"
.It Pa /dev/sa0
The default tape device, if not overridden by the
.Ev TAPE
environment variable or the
.Fl f
option.
.El
.Sh EXIT STATUS
.Ex -std
.Sh EXAMPLES
The following creates a new archive
called
.Ar file.tar.gz
that contains two files
.Ar source.c
and
.Ar source.h :
.Dl Nm Fl czf Pa file.tar.gz Pa source.c Pa source.h
.Pp
To view a detailed table of contents for this
archive:
.Dl Nm Fl tvf Pa file.tar.gz
.Pp
To extract all entries from the archive on
the default tape drive:
.Dl Nm Fl x
.Pp
To examine the contents of an ISO 9660 cdrom image:
.Dl Nm Fl tf Pa image.iso
.Pp
To move file hierarchies, invoke
.Nm
as
.Dl Nm Fl cf Pa - Fl C Pa srcdir\ . | Nm Fl xpf Pa - Fl C Pa destdir
or more traditionally
.Dl cd srcdir \&; Nm Fl cf Pa -\ . | ( cd destdir \&; Nm Fl xpf Pa - )
.Pp
In create mode, the list of files and directories to be archived
can also include directory change instructions of the form
.Cm -C Ns Pa foo/baz
and archive inclusions of the form
.Cm @ Ns Pa archive-file .
For example, the command line
.Dl Nm Fl c Fl f Pa new.tar Pa foo1 Cm @ Ns Pa old.tgz Cm -C Ns Pa /tmp Pa foo2
will create a new archive
.Pa new.tar .
.Nm
will read the file
.Pa foo1
from the current directory and add it to the output archive.
It will then read each entry from
.Pa old.tgz
and add those entries to the output archive.
Finally, it will switch to the
.Pa /tmp
directory and add
.Pa foo2
to the output archive.
.Pp
An input file in
.Xr mtree 5
format can be used to create an output archive with arbitrary ownership,
permissions, or names that differ from existing data on disk:
.Pp
.Dl $ cat input.mtree
.Dl #mtree
.Dl usr/bin uid=0 gid=0 mode=0755 type=dir
.Dl usr/bin/ls uid=0 gid=0 mode=0755 type=file content=myls
.Dl $ tar -cvf output.tar @input.mtree
.Pp
The
.Fl -newer
and
.Fl -newer-mtime
switches accept a variety of common date and time specifications, including
.Dq 12 Mar 2005 7:14:29pm ,
.Dq 2005-03-12 19:14 ,
.Dq 5 minutes ago ,
and
.Dq 19:14 PST May 1 .
.Pp
The
.Fl -options
argument can be used to control various details of archive generation
or reading.
For example, you can generate mtree output which only contains
.Cm type , Cm time ,
and
.Cm uid
keywords:
.Dl Nm Fl cf Pa file.tar Fl -format=mtree Fl -options='!all,type,time,uid' Pa dir
or you can set the compression level used by gzip or xz compression:
.Dl Nm Fl czf Pa file.tar Fl -options='compression-level=9' .
For more details, see the explanation of the
.Fn archive_read_set_options
and
.Fn archive_write_set_options
API calls that are described in
.Xr archive_read 3
and
.Xr archive_write 3 .
.Sh COMPATIBILITY
The bundled-arguments format is supported for compatibility
with historic implementations.
It consists of an initial word (with no leading - character) in which
each character indicates an option.
Arguments follow as separate words.
The order of the arguments must match the order
of the corresponding characters in the bundled command word.
For example,
.Dl Nm Cm tbf 32 Pa file.tar
specifies three flags
.Cm t ,
.Cm b ,
and
.Cm f .
The
.Cm b
and
.Cm f
flags both require arguments,
so there must be two additional items
on the command line.
The
.Ar 32
is the argument to the
.Cm b
flag, and
.Ar file.tar
is the argument to the
.Cm f
flag.
.Pp
The mode options c, r, t, u, and x and the options
b, f, l, m, o, v, and w comply with SUSv2.
.Pp
For maximum portability, scripts that invoke
.Nm tar
should use the bundled-argument format above, should limit
themselves to the
.Cm c ,
.Cm t ,
and
.Cm x
modes, and the
.Cm b ,
.Cm f ,
.Cm m ,
.Cm v ,
and
.Cm w
options.
.Pp
Additional long options are provided to improve compatibility with other
tar implementations.
.Sh SECURITY
Certain security issues are common to many archiving programs, including
.Nm .
In particular, carefully-crafted archives can request that
.Nm
extract files to locations outside of the target directory.
This can potentially be used to cause unwitting users to overwrite
files they did not intend to overwrite.
If the archive is being extracted by the superuser, any file
on the system can potentially be overwritten.
There are three ways this can happen.
Although
.Nm
has mechanisms to protect against each one,
savvy users should be aware of the implications:
.Bl -bullet -width indent
.It
Archive entries can have absolute pathnames.
By default,
.Nm
removes the leading
.Pa /
character from filenames before restoring them to guard against this problem.
.It
Archive entries can have pathnames that include
.Pa ..
components.
By default,
.Nm
will not extract files containing
.Pa ..
components in their pathname.
.It
Archive entries can exploit symbolic links to restore
files to other directories.
An archive can restore a symbolic link to another directory,
then use that link to restore a file into that directory.
To guard against this,
.Nm
checks each extracted path for symlinks.
If the final path element is a symlink, it will be removed
and replaced with the archive entry.
If
.Fl U
is specified, any intermediate symlink will also be unconditionally removed.
If neither
.Fl U
nor
.Fl P
is specified,
.Nm
will refuse to extract the entry.
.El
To protect yourself, you should be wary of any archives that
come from untrusted sources.
You should examine the contents of an archive with
.Dl Nm Fl tf Pa filename
before extraction.
You should use the
.Fl k
option to ensure that
.Nm
will not overwrite any existing files or the
.Fl U
option to remove any pre-existing files.
You should generally not extract archives while running with super-user
privileges.
Note that the
.Fl P
option to
.Nm
disables the security checks above and allows you to extract
an archive while preserving any absolute pathnames,
.Pa ..
components, or symlinks to other directories.

.Sh STANDARDS
There is no current POSIX standard for the tar command; it appeared
in
.St -p1003.1-96
but was dropped from
.St -p1003.1-2001 .
The options used by this implementation were developed by surveying a
number of existing tar implementations as well as the old POSIX specification
for tar and the current POSIX specification for pax.
.Pp
The ustar and pax interchange file formats are defined by
.St -p1003.1-2001
for the pax command.
.Sh HISTORY
A
.Nm tar
command appeared in Seventh Edition Unix, which was released in January, 1979.
There have been numerous other implementations,
many of which extended the file format.
John Gilmore's
.Nm pdtar
public-domain implementation (circa November, 1987)
was quite influential, and formed the basis of GNU tar.
GNU tar was included as the standard system tar
in
.Fx
beginning with
.Fx 1.0 .
.Pp
This is a complete re-implementation based on the
.Xr libarchive 3
library.
.Sh BUGS
This program follows
.St -p1003.1-96
for the definition of the
.Fl l
option.
Note that GNU tar prior to version 1.15 treated
.Fl l
as a synonym for the
.Fl -one-file-system
option.
.Pp
The
.Fl C Pa dir
option may differ from historic implementations.
.Pp
All archive output is written in correctly-sized blocks, even
if the output is being compressed.
Whether or not the last output block is padded to a full
block size varies depending on the format and the
output device.
For tar and cpio formats, the last block of output is padded
to a full block size if the output is being
written to standard output or to a character or block device such as
a tape drive.
If the output is being written to a regular file, the last block
will not be padded.
Many compressors, including
.Xr gzip 1
and
.Xr bzip2 1 ,
complain about the null padding when decompressing an archive created by
.Nm ,
although they still extract it correctly.
.Pp
The compression and decompression is implemented internally, so
there may be insignificant differences between the compressed output
generated by
.Dl Nm Fl czf Pa - file
and that generated by
.Dl Nm Fl cf Pa - file | Nm gzip
.Pp
The default should be to read and write archives to the standard I/O paths,
but tradition (and POSIX) dictates otherwise.
.Pp
The
.Cm r
and
.Cm u
modes require that the archive be uncompressed
and located in a regular file on disk.
Other archives can be modified using
.Cm c
mode with the
.Pa @archive-file
extension.
.Pp
To archive a file called
.Pa @foo
or
.Pa -foo
you must specify it as
.Pa ./@foo
or
.Pa ./-foo ,
respectively.
.Pp
In create mode, a leading
.Pa ./
is always removed.
A leading
.Pa /
is stripped unless the
.Fl P
option is specified.
.Pp
There needs to be better support for file selection on both create
and extract.
.Pp
There is not yet any support for multi-volume archives or for archiving
sparse files.
.Pp
Converting between dissimilar archive formats (such as tar and cpio) using the
.Cm @ Ns Pa -
convention can cause hard link information to be lost.
(This is a consequence of the incompatible ways that different archive
formats store hardlink information.)
.Pp
There are alternative long options for many of the short options that
are deliberately not documented.

/*
* This getopt implementation has two key features that common
* getopt_long() implementations lack. Apart from those, it's a
* straightforward option parser, considerably simplified by not
* needing to support the wealth of exotic getopt_long() features. It
* has, of course, been shamelessly tailored for bsdtar. (If you're
* looking for a generic getopt_long() implementation for your
* project, I recommend Gregory Pietsch's public domain getopt_long()
* implementation.) The two additional features are:
*
* Old-style tar arguments: The original tar implementation treated
* the first argument word as a list of single-character option
* letters. All arguments follow as separate words. For example,
* tar xbf 32 /dev/tape
* Here, the "xbf" is three option letters, "32" is the argument for
* "b" and "/dev/tape" is the argument for "f". We support this usage
* if the first command-line argument does not begin with '-'. We
* also allow regular short and long options to follow, e.g.,
* tar xbf 32 /dev/tape -P --format=pax
*
* -W long options: There's an obscure GNU convention (only rarely
* supported even there) that allows "-W option=argument" as an
* alternative way to support long options. This was supported in
* early bsdtar as a way to access long options on platforms that did
* not support getopt_long() and is preserved here for backwards
* compatibility. (Of course, if I'd started with a custom
* command-line parser from the beginning, I would have had normal
* long option support on every platform so that hack wouldn't have
* been necessary. Oh, well. Some mistakes you just have to live
* with.)
*
* TODO: We should be able to use this to pull files and intermingled
* options (such as -C) from the command line in write mode. That
* will require a little rethinking of the argument handling in
* bsdtar.c.
*
* TODO: If we want to support arbitrary command-line options from -T
* input (as GNU tar does), we may need to extend this to handle option
* words from sources other than argv/arc. I'm not really sure if I
* like that feature of GNU tar, so it's certainly not a priority.

* Try to figure out how deep we can go in our tests. Assumes that
* the first call to this function has the longest starting cwd (which
* is currently "<testdir>/original"). This is mostly to work around
* limits in our Win32 support.
*
* Background: On Posix systems, PATH_MAX is merely a limit on the
* length of the string passed into a system call. By repeatedly
* calling chdir(), you can work with arbitrarily long paths on such
* systems. In contrast, Win32 APIs apply PATH_MAX limits to the full
* absolute path, so the permissible length of a system call argument
* varies with the cwd. Some APIs actually enforce limits
* significantly less than PATH_MAX to ensure that you can create
* files within the current working directory. The Win32 limits also
* apply to Cygwin before 1.7.
*
* Someday, I want to convert the Win32 support to use newer
* wide-character paths with '\\?\' prefix, which has a 32k PATH_MAX
* instead of the rather anemic 260 character limit of the older
* system calls. Then we can drop this mess (unless we want to
* continue to special-case Cygwin 1.5 and earlier).

* d0/l1 can't be extracted, none of these three will be
* extracted.
*
* It may be worth extending this test to force a particular
* archiving order so as to exercise both of the cases described

* This is a new directory-walking system that addresses a number

* pathname-length limits (other than the size of 'int'), handles
* deep logical traversals, uses considerably less memory, and has
* an opaque interface (easier to modify in the future).
*
* Internally, it keeps a single list of "tree_entry" items that
* represent filesystem objects that require further attention.
* Non-directories are not kept in memory: they are pulled from
* readdir(), returned to the client, then freed as soon as possible.
* Any directory entry to be traversed gets pushed onto the stack.
*
* There is surprisingly little information that needs to be kept for
* each item on the stack. Just the name, depth (represented here as the
* string length of the parent directory's pathname), and some markers
* indicating how to get back to the parent (via chdir("..") for a
* regular dir or via fchdir(2) for a symlink).

* * Supports very deep logical traversals. The fts package

* to the pending list; do_chdir() actually executes any pending chdir.
