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
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
upload44
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.
upload44 [
-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
