swpackage — Package a software distribution.
swpackage [−p] [−s psf_file] [−f file] [−x option=value] \
[−X options_file] [−W option] [software_selections] [@targets]
swpackage reads a Product Specification File (PSF) and writes a distribution to the specified target. If no options are given a PSF is read on stdin and a distribution is written to the default target either a directory, device, or standard output. To specify standard output use a dash '−' as the target. This implementation only supports writing to stdout.
software_selections
Refer to the software objects (products, filesets) on which to be operated. (Not yet implemented)targets
Refers to the software_collection where the software selections are to be applied. To specify standard output use a dash '−', this overrides media_type setting to 'serial'. Target may be a file system directory, or device file or '−' Currently this implementation only supports a serial archive written to stdout.-f FILE
Reads software_selections from FILE. (Not implemented).-p
Preview the package. Perform all the packaging operations except writing the target. In verbose level 1, nothing is written. Higher verbose levels write information on stdout. Error and warning messages are written to stderr for verbose levels 1 and higher.-s PSF
Specify the PSF file, "−" is standard input.-x option=value
Specify the extended option overriding the defaults file value.-X FILE
Specify the extended options filename, FILE, overriding the default filenames. This option may be given more then once. If the resulting specified value is an empty string then reading of any options file is disabled.-v
(Implementation extension.) Given one time it is identical to −x verbose=2. This option can be given multiple times with increasing effect. level 0: silent on stdout and stderr (not implemented). level 1: fatal and warning messages. −v level 2: level 1 plus file list and trailer message. −vv level 3: level 2 verbose tar-like listing. −vvv level 4: level 3 extra verbose tar listing.-b BYTES
Set blocksize to BYTES number of bytes (octets). The default is 10240. (implementation extension)−−version, −V
Show version. (Implementation extension)−−help
Show help (Implementation extension)-W option[,option,...]
Specify the implementation extension option. Syntax: −W option[=option_argument[,option...] Options may be separated by a comma. The implementation extension options may also be given individually using the '−−long-option[=option_arg]' syntax.-W cksum
Compute posix cksum of the individual files.-W file-digests -W digests
Compute md5 digests of the individual files. (−W digests is deprecated, use −W file-digests).-W files
Store the distribution file list in .../dfiles/files.-W dir=NAME
Use NAME as the path name prefix of a distribution and also as the value of the distribution.control_directory and distribution.tag attribute (if not set). May be set to an empty string to eliminate stray leading "./".-W sign
Compute the md5sum, sha1sum and adjunct_md5sum digests and sign the package.-W dummy-sign
Same as −W sign except use a dummy signature. The signer program is not run and no password is required.-W signer-pgm=SIGNER
Recognized SIGNERs are GPG, PGP2.6, and PGP5. swverify only supports GPG, however, other types can be verified manually using the options of swverify and command line utilities.-W archive-digests
Compute the md5sum, sha1sum and adjunct_md5sum digests. See sw(5) for info on the digest and signed data input files. The sha1sum and md5sum attributes have identical input streams.-W no-sha1
Do not compute the sha1 digest even if directed to by other options. (Deprecated: There is limited reason to use this option).-W signed-file
Write only the signed data to the specified target but do not sign. (Deprecated: There is limited reason to use this option).-W gpg-name=NAME
Use NAME as the user ID to sign. NAME becomes the option arg of the gpg −−local-user option.-W gpg-path=PATH
Use PATH as the gpg homedir.-W gzip
Not implemented.-W bzip2
Not implemented.-W source=FILE
Use serial archive located at FILE as the source instead of the file system. The files referred by the PSF are taken from the serial archive and not the file system.-W numeric-owner
Same as GNU tar option. Emitted archive has only uid and gids.-W absolute-names
Same as GNU tar option. Leading slash '/' are always stripped unless this option is given.-W format=FORMAT
FORMAT is one of:
ustar is the POSIX.1 tar format capable of storing
pathnames up to 255 characters in length.
Identical to GNU tar 1.15.1 −−format=ustar
This is the default format but may be changed by
the options files.
ustar0 is a different POSIX.1 tar personality.
Identical to GNU tar 1.13.25 −−posix −b1 for 99 char pathnames
Has different rendering of device numbers for non-device files,
but otherwise identical to 'ustar'
gnu Identical to GNU tar version 1.15.1 −−format=gnu
oldgnu Identical to GNU tar version 1.13 and later with
block size set to 1. i.e. with option −b1.
Also identical to GNU tar 1.15.1 −−format=oldgnu
gnutar same as oldgnu, oldgnu preferred.
pax Extended header tar (Not implemented).
odc Posix.1 cpio (magic 070707).

Support for embedded cryptographic signature.
Package signing is accomplished by including, as a package attribute, a detached signature in the package metadata (the catalog section of the package). The signed data is the catalog section of the package (see sw(5) for a description) excluding the signature files archive header and data. The package leading directory that does not contain the /catalog/ directory in its name is not included in the signed stream. The signed stream is terminated by two (2) null tar blocks (which are not in the actual package file). The storage section (or payload) of the package is included in the signed data by computing its md5 and sha1 message digests and storing these as attributes in the catalog section.
The signature is generated by the file system signing utility. Currently, swpackage supports GPG PGP-2.6 and PGP-5. The default is GPG but can be selected using the -Wsigner-pgm command line option and the swpackage.swbis_signer_pgm defaults file option. The options and program can the displayed with the -Wshow-signer-pgm option. The options in each case produce a detached ascii-armored signature. The maximum length for the ascii armored file is 1023 bytes.
The passphrase is read by the swpackage utility from the process controlling terminal or stdin if there is no controlling terminal. A separate dedicated process reads the passphrase which may be up to 239 characters in length. It is immediately written into a Unix pipe, read by the signer program on file descriptor three (fd=3), its memory location wiped, and the dedicated process exited.
swpackage does not perform verification of the embedded cryptographic signature, although, a description is included here for completness.
Verification requires verifying the payload section md5 and sha1 message digests and then verifying the signature. Naturally, it is required that the signed data include the payload messages digests. See swverify.
Verification requires re-creating the signed and digested byte streams from the archive file. This is not possible using any known extant tar reading utility because of a lack of ability to write selected archive members to stdout instead of installing in the file system; however, the swverify utility can be used to write these bytes streams to stdout allowing manual inspection and verification. See swverify.
Verification using standard GNU/Linux tools is possible if the archive is installed in the file system. Success depends on the following factors:
1) The tar utility preserves modification times
(e.g. not GNU tar 1.3.19).
2) The archive does not contain Symbolic Links
(see sw(5) for explanation).
3) The file system is a Unix file system (e.g. ext2).
4) The package was created using −Wformat=gnutar or, −Wformat=ustar
with no file name longer than 99 octets.
Recreating the signed and digested byte streams is then accomplished using GNU tar and the file list stored in the \<path\>/catalog/dfiles/files attribute file as follows: In this example, the package has a single path name prefix called, namedir and the file owner/group are root. These restrictions are suited to source packages. Verify the signature:
#!/bin/sh
tar cf − −b1 −−owner=root −−group=root \
−−exclude=namedir/catalog/dfiles/signature \
namedir/catalog | gpg −−verify namedir/catalog/dfiles/signature −
If this fails try using GNU tar option −−posix. If this fails then you are out of luck as nothing in the catalog section can be trusted. Verify the payload digests:
#!/bin/sh
grep −v namedir/catalog namedir/catalog/dfiles/files | \
tar cf − −b1 −−owner=root −−group=root \
−−files-from=− −−no-recursion | md5sum
cat namedir/catalog/dfiles/md5sum
Likewise for the sha1 digest. If the package has symbolic links, Verify the adjunct_md5sum:
#!/bin/sh
grep −v namedir/catalog namedir/catalog/dfiles/files | \
( while read file; do if [ ! −h $file ]; then echo $file; fi done; )|\
tar cf − −b1 −−owner=root −−group=root \
−−files-from=− −−no-recursion | md5sum
cat namedir/catalog/dfiles/adjunct_md5sum
The symbolic link files must be verified manually by comparing to the INFO file information.
The output format is either one of two formats specified in POSIX.1 (ISO/IEC 9945-1) which are tar (header magic=ustar) or cpio (header magic=070707). The default format of the swbis implementation is "ustar". The POSIX spec under specifies definitions for some of the ustar header fields. The personality of the default swbis ustar format mimics GNU tar 1.15.1 and is designed to be compliant to POSIX.1. The personality of the "ustar0" format mimics, for pathnames less than 99 octets, GNU tar 1.13.25 using the "−b1 −−posix" options. This bit-for-bit sameness does not exist for pathnames greater than 99 chars as swbis follows the POSIX spec and GNU tar 1.13.25 does not. The "ustar0" ustar personality is deprecated. It is only slightly different from 'ustar' in how device number fields are filled (with spaces, zeros or NULs) for non-device files. In addition the swbis implementation supports several other tar variants including bit-for-bit mimicry of GNU tar (1.13.25) default format which uses a non-standard name split and file type (type 'L'). This format is known as '−−format=oldgnu'. Also supported is the gnu format of GNU tar 1.15.1 specified by '−−format=gnu' The defacto cpio formats are also supported. "new ASCII" (sometimes called SVR4 cpio) and "crc" cpio formats with header magic "070701" and "070702" respectively. Support for "pax Interchange Format" (Extended header tar) described in IEEE 1003.1-2001 under the "pax" manual page is planned. The entirety of the output byte stream is a single valid file of one the formats mentioned above. The swbis implementation writes its output to stdout. The default output block size is 10240 bytes. The last block is not padded and therefore the last write(2) may be a short write. The selected block size does not affect the output file contents. The swbis implementation is biased, in terms of capability and default settings, to the tar format. Package signing is only supported in tar format.
The input file is called a product specification file or PSF. It contains information to direct swpackage and information that is package meta-data [that is merely transferred unchanged into the global INDEX file]. A PSF may contain object keywords, attributes (keyword/value pairs) and Extended Definitions (described below). An object keyword connotes a logical object (i.e. software structure) supported by the standard. An object keyword does not have a value field after it, as it contains Attributes and Extended Definitions. An attribute keyword conotes an attribute which is always in the form of a keyword/value pair. Attribute keywords not recognized by the standard are allowed and are transferred into the INDEX file. Object keywords not recognized by the standard are not allowed and will generate an error. Extended Definitions may only appear in a PSF (never in a INDEX or INFO created by swpackage). Extended Definitions are translated [by swpackage] into object keywords (objects) and attributes recognized by the standard. Comments in a PSF are not transferred into the INDEX file by the swbis implementation of swpackage. The file syntax is the same as a INDEX, or INFO file. A PSF may contain all objects defined by the standard as well as extended definitions. For additional information see XDSA C701 http://www.opengroup.org/publications/catalog/c701.htm, or sw manual page.
A Product Specification File (PSF) can contain Extended Definitions in the fileset, product or bundle software definitions. They would have the same level or containment relationship as a file or control_file definition in the same contaning object. Extended Definitions represent a minimal, expressive form for specifying files and file attributes. Their use in a PSF is optional in that an equivalent PSF can be constructed without using them, however, their use is encouraged for the sake of brevity and orthogonality. The swbis implementation requires that no [ordinary] attributes appear after Extended Definitions in the containing object, and, requires that Extended Definitions appear before logically contained objects. That is, the parser uses the next object keyword to syntacticly and logically terminate the current object even if the current object has logically contained objects.

control_file source [path]
The source attribute defines the location in distributors's development system where the swpackage utility will find the script. The keyword is the value of the tag attribute and tells the utilities when to execute the script. The path attribute is optional and specifies the file name in the packages distribution relative to the control_directory for software containing the script. If not given the tag value is used as the filename.
directory source [destination]
Applies the source attribute as the directory under which the subsequently listed files are located. If destination is defined it will be used as a prefix to the path (implied) file definition. source is typically a temporary or build location and dest is its unrealized absolute pathname destination.
file *
Specifies every file in current source directory. The directory extended definition must be used before the recursive specification.
file [−t type] [−m mode] [−o owner[,uid]] [−g group[,gid]] [−n] [−v] source [path]
source
source defines the pathname of the file to be used as the source of file data and/or attributes. If it is a relative path, then swpackage searches for this file relative to the the source argument of the directory keyword, if set. If directory keyword is not set then the search is relative to the current working directory of the swpackage utility's invocation. All attributes for the destination file are taken from the source file, unless a file_permissions keyword is active, or the −m, −o, or −g options are also included in the file specification.path
path defines the destination path where the file will be created or installed. If it is a relative path, then the destination path of the of the directory keyword must be active and will be used as the path prefix. If path is not specified then source is used as the value of path and directory mapping applied (if active).-t type
type may one of 'd' (directory), or 'h' (hard link), or 's' (symbolic link). −t d Create a directory. If path is not specified source is used as the path attribute. −t h Create a hard link. path and source are specified. source is used as the value of the link_source attribute, and path is the value of the path attribute. −t s Create a symbolic link. path and source are specified. source is used as the value of the link_source attribute, and path is the value of the path attribute.-m mode
mode defines the octal mode for the file.
file_permissions [−m mode] [−u umask] [−o [owner[,]][uid]] [−g [group[,]][gid]]
Applies to subsequently listed file definitions in a fileset. These attributes will apply where the file attributes were not specified explicitly in a file definition. Subsequent file_permissions definitions simply replace previous definitions (resetting all the options). To reset the file_permission state (i.e. turn it off) use one of the following: file_permissions "" or the preferred way is file_permissions −u 000
exclude source
Excludes a previously included file or an entire directory.
include <filename
The contents of filename may be more definitions for files. The syntax of the included file is PSF syntax.
This section describes attribute usage and conventions imposed by the swbis implementation. Not all attributes are listed here. Those that are have important effects or particular interest.
The standard defines a limited set of attributes for the distribution object. An expanded set is suggested by the informative annex however a conforming implementation is not required act on them. The reason for this is a distribution may be acted upon by a conforming utility in such a way that attributes of the distribution become invalid. For this reason, some attributes that refer to an entire "package" [in other package managers] are referred from the product object and attain their broadened scope by the distributor's convention that their distribution contains just one product. For example, the package NAME and VERSION are referred from the product tag and revision, not the distribution's. This convention supports multiple products in a distribution and is consistent with the standard. tag
tag is the short, file system friendly, name of the distribution. Providing a distribution tag is optional. The swbis implementation will use this as the [single] path name prefix if there is no distribution.control_directory attribute. A distribution tag attribute and swpackage's response to it is an implementation extension. The leading package path can also be controlled with the ”−W dir” option.control_directory
control_directory, in a distribution object, is the constant leading package path. Providing this attribute is optional. A distribution control_directory attribute and swpackage's response to it is an implementation extension. The leading package path can also be controlled with the ”−W dir” option. This attribute will be generated by swpackage if not set in a PSF.
A bundle defines a collection of products whether or not the distribution has all the products present. tag
tag is the short, file system friendly, name of the bundle. This value is used by the swbis implementation as a path name component in the installed software catalog. If it is not present the product tag is used.
A product defines the software product. tag
tag is the short, file system friendly, name of the product. This value is used by the swbis implementation as a path name component in the installed software catalog. It is required. The swbis implementation uses it in a way that is analogous to the RPMTAG_NAME attribute.control_directory
Is the directory name in the distribution under which the product contents are located. This value has no affect on the installed software catalog. If it is not given in a PSF then the tag is used.revision
Is the product revision. It should not contain a "RELEASE" attribute part or other version suffix modifiers. This value is used by the swbis implementation as a path name component in the installed software catalog. It is required by swinstall.vendor_tag
This is a short identifying name of the distributor that supplied the product and associates the vendor object from the INDEX file. This attribute is optional. This attribute value should strive to be unique among all distributors. It is one of the version distinguishing attributes of a product specified by the standard. It is transfered into the installed_software catalog (not as a path name component) by swinstall. If this attribute exists there should also be a vendor object in the PSF in the distribution object that has this tag. This attribute is assigned the value of RPMTAG_RELEASE by swpackage when translating an RPM. In this capacity it serves to distinguish products with the same revision and tag from the same or different distributor. It most closely maps to the RPMTAG_RELEASE or "debian_revision" attributes.
A fileset defines the fileset. tag
tag is the short, file system friendly, name of the fileset. It is required.control_directory
Is the directory name in the product under which the fileset contents are located. This value has no affect on the installed software catalog. If it is not given in a PSF then the tag is used.
This PSF packages every file is current directory. It uses nil control directories so the package structure does not change relative to a vanilla tarball.

This is a sample PSF for a runtime package. It implies multiple products (e.g. sub-packages) using the bundle.contents attribute. Since the bundle and product tags exist in a un-regulated namespace and are seen by end users they should be carefully chosen. Note that the bundle and product have the same tag which may force downstream users to disambiguate using software selection syntax such as fooit,bv=* or fooit,pv=* .

Swpackage does not use any archive writing utilities, it has its own code to generate archives. Package signing uses one of the following: /usr/bin/gpg /usr/bin/pgp (PGP 2.6.x) /usr/bin/pgps (PGP 5) Swpackage will use /usr/bin/uuidgen if present to create the uuid.

A comment after an object keyword is wrongly not allowed by this PSF parser. The −−dir="" does not do what one would expect sometimes. The output stream content is unaffected by the blocksize, that is the last write may be short write. Signing is broken for cpio format archives.
