Note

This information is provided primarily for Shorewall developers. Users are expected to install from pre-built tarballs or packages.

Git Taxonomy

The Shorewall Git tree at Sourceforge serves as the master repository for Shorewall 4.4 and later versions. It is not possible to simply export a directory from Git and run the install.sh script in that directory. A build step is required to produce a directory that is suitable for the install.sh script to run in.

trunk

The development branch of each product is kept here.

  • Shorewall

  • Shorewall6

  • Shorewall-lite

  • Shorewall6-lite

There are also several other directories which are described in the following sub-sections.

trunk/docs

The development release XML documents. Depending on the point in the release cycle, these documents may also apply to the current stable version. In that case, there is no docs directory in that release's directory in branches.

trunk/web

The files from the web site that are maintained in HTML format. are kept in this directory.

trunk/manpages, trunk/manpages6, trunk/manpages-lite and trunk/manpages6-lite

The development release XML manpages. Depending on the point in the release cycle, these documents may also apply to the current stable version.

trunk/tools

This is where the release and build tools are kept. There are two subordinate directories:

trunk/tools/build

Tools for building and uploading new releases.

trunk/tools/web

Tools for publishing web content.

Build Tools

As described above, the build tools are kept in trunk/tools/build. They are described in the following sections.

setversion

The setversion script updates the version number in a directory. The script is run with the current working directory being trunk.

setversion version

The version may either be a minor version or a patch version.

build44

This is the script that builds Shorewall packages from Git.

The script copies content from Git using the git archive command. It then uses that content to build the packages. In addition to the usual Gnu utilities, the following software is required:

rpmbuild (I use rpm version 4.4.2.3-20.3)

Required to build the RPM packages.

xsltproc (libxslt -- I use version 1.1.24-19.1)

Required to convert the XML documents to other formats.

Docbook XSL Stylesheets (I use docbook-xsl-stylesheets version 1.74.0-1.35)

Required to convert the XML documents to other formats.

Perl (I use Perl 5.10.0-62.17.1)

Required to massage some of the config files.

xmlto (I use version 0.0.18-182.27)

Required to convert the XML manpages to manpages.

You should ensure that you have the latest script. The scripts change periodically as we move through the release cycles.

The scripts may need to be modified to fit your particular environment. There are a number of variables that are set near the front of the script:

STYLESHEET

Must point to the XHTML docbook.xsl stylesheet from your Docbook XSL Stylesheets installation.

LOGDIR

Directory where you want the build log placed. Defaults to the current working directory.

RPMDIR

Points to your RPM directory .

DIR

Directory where you want the release to be built. Defaults to the current working directory.

GPG

Command to be used for signing your packages

GIT

Shorewall GIT repository

The scripts assume that there will be a separete build directory per major release. To build a release, you cd to the appropriate directory and run the build script.

The general form of the build command is:

build44 [ -options ] release [ prior release ]

where

options

are one of the following. If no options are given then all options are assumed

t

build tar files

r

build RPMs

S

sign the packages using GnuPg

c

Build the shorewall package.

l

Build the shorewall-lite package.

6

Build the shorewall6 package.

L

Build the shorewall6-lite package.

release

The release version to build. Must match the version in the associated Git path.

prior release

The release to be used to generate patch files.

Example 1 - Build Shorewall 4.3.7 and generate patches against 4.3.6:

build44 4.3.7 4.3.6

Example 2 - Build Shorewall 4.2.7.1 Shorewall and generate patches against 4.2.7:

build44 -trSc 4.3.7.1 4.3.7

upload

This script is used to upload a release to lists.shorewall.net. The command is run in the build directory for the major release of the product.

upload [ -products ] release

where

products

specifes the products to upload. If not given, all products are uploaded. This option is generally given only when uploading a patch release.

c

Upload the shorewall package.

l

Upload the shorewall-lite package.

6

Upload the shorewall6 package.

L

Upload the shorewall6-lite package.

release

The version number of the release to update.

Example 1 - Upload release 4.3.7:

upload 4.3.7

Example 2 - Upload shorewall-perl-4.3.7.3:

upload -p 4.3.7.3
