swid_generator 0.3.0

Application which generates SWID-Tags from Linux installed packages, using tools like DPGK or RPM.

A small application for Python 2 and 3 which generates SWID tags from Linux package managers like dpkg, rpm or pacman.

Usage

The tool provides 2 subcommands to generate SWID tags or Software IDs.

Generate SWID tags:

usage: swid_generator swid [-h] [--env {auto,dpkg,pacman,rpm}]
                           [--doc-separator DOCUMENT_SEPARATOR] [--regid REGID]
                           [--entity-name ENTITY_NAME] [--full] [--pretty]
                           [--software-id SOFTWARE-ID | --package PACKAGE]

Generate SWID tags.

optional arguments:
  -h, --help            Show this help message and exit.
  --env {auto,dpkg,pacman,rpm}
                        The package manager environment to be used. Defaults to "auto".
                        If the environment can not be autodetected, the exit code is set
                        to 3.
  --doc-separator DOCUMENT_SEPARATOR
                        The separator string by which the SWID XML documents are
                        separated. Example: For one newline, use $'\n'.
  --regid REGID         The regid to use in the generated output. May not contain any
                        whitespace characters. Default is
                        "regid.2004-03.org.strongswan".
  --entity-name ENTITY_NAME
                        The entity name used in the <Entity> XML tag. Default is
                        "strongSwan Project".
  --full                Dump the full SWID tags including file tags for each package.
  --pretty              Indent the XML output.

targeted requests:
  You may do a targeted request against either a Software-ID or a package name. The
  output only contains a SWID tag if the argument fully matches the given target. If
  no matching SWID tag is found, the output is empty and the exit code is set to 1.

  --software-id SOFTWARE-ID
                        Do a targeted request for the specified Software-ID. A Software-
                        ID is made up as follows: "{regid}_{unique-id}". Example: "regid
                        .2004-03.org.strongswan_Ubuntu_12.04-i686-strongswan-4.5.2-1.2".
                        If no matching package is found, the output is empty and the
                        exit code is set to 1.
  --package PACKAGE     Do a targeted request for the specified package name. The
                        package name corresponds to a package name returned by the
                        environment's package manager, e.g "glibc-headers" on a dpkg
                        managed environment. If no matching package is found, the output
                        is empty and the exit code is set to 1.

Generate Software IDs:

usage: swid_generator software-id [-h] [--env {auto,dpkg,pacman,rpm}]
                                  [--doc-separator DOCUMENT_SEPARATOR] [--regid REGID]

Generate Software-IDs.

optional arguments:
  -h, --help            Show this help message and exit.
  --env {auto,dpkg,pacman,rpm}
                        The package manager environment to be used. Defaults to "auto".
                        If the environment can not be autodetected, the exit code is set
                        to 3.
  --doc-separator DOCUMENT_SEPARATOR
                        The separator string by which the SWID XML documents are
                        separated. Example: For one newline, use $'\n'.
  --regid REGID         The regid to use in the generated output. May not contain any
                        whitespace characters. Default is
                        "regid.2004-03.org.strongswan".

Possible Return Codes

If the application fails somehow, an exit code is set appropriately:

  • 1: A targeted request did not return any results.
  • 2: Invalid arguments passed.
  • 3: Either the given environment is not installed or the environment could not be autodetected.

The exit code can be shown with:

$ echo $?

Reserved Characters

URI reserved characters (:/?#[]@!$&'()*+,;=) in the package name / version section of the Unique-ID are replaced with a tilde (~) sign.

Installation

The following package managers are supported:

  • dpkg (Debian, Ubuntu, Linux Mint, …)
  • pacman (Arch Linux, Manjaro, …)
  • rpm (Fedora, Red Hat, OpenSUSE, …)

The following Python versions are fully supported:

  • Python 2.7
  • Python 3.3+
  • PyPy

Python 2.6 should also work, but you need to manually install the argparse library from the Python Package Index (or via your regular package manager).

Install with pip

The recommended way to install swidGenerator is using pip:

$ sudo pip install -U swid_generator

This will automatically install the latest version from the Python Package Index.

Manual Installation

Get code:

$ wget https://github.com/strongswan/swidGenerator/archive/v0.3.0.zip
$ unzip v0.3.0.zip
$ cd swidGenerator-0.3.0

Install:

$ sudo python setup.py install

Development Installation

To make invocation easier during development, use pip’s editable installation feature instead, which means that changes in the code are immediately reflected:

$ pip install -e .

Invoke application

If you have installed the application, you can run the generator via the swid_generator binary:

$ swid_generator

You can also invoke the generator directly from the source directory, without any prior installation:

$ python -m swid_generator.main

Testing

Setup

Testing for swidGenerator is set up using Tox and pytest. Violations of the coding guidelines (PEP8 with a few small tweaks) are counted as test fails.

The only requirement to run the tests is tox:

$ pip install tox

Running tests

To test only a single Python version, use the -e parameter:

$ tox -e py27

To see the coverage, use the cov testenv (which uses Python 2.7 by default):

$ tox -e cov

You can also combine multiple testenvs, just make sure that you have the corresponding Python versions installed:

$ tox -e py27,py34,cov

CI

We use different continuous integration / quality assurance services:

Coding Guidelines

Use PEP8 with --max-line-length=109 and the following error codes ignored: E126 E127 E128.

Packaging

Upload to PyPI

To upload a new version to PyPI, configure your .pypirc and execute the following commands:

$ pip install wheel
$ python setup.py register
$ python setup.py sdist upload
$ python setup.py bdist_wheel upload

Building .deb Package

You can create an unsigned .deb package using the package.sh script:

$ ./package.sh
...
$ ls dist/
swid-generator_0.1.1-1_all.deb

Note that this only works on a debian based system. Take a look at the comments in the script for more information.

Building the Manpage

You can build a manpage using Sphinx:

$ cd docs
$ make man
$ man ./_build/man/swid_generator.1
