In order to provide pre-compiled binaries of third-party applications for FreeBSD, the Ports Collection is regularly built on one of the “Package Building Clusters.” Currently, the main cluster in use is at http://pointyhat.FreeBSD.org.
This article documents the internal workings of the cluster.
Note: Many of the details will be of interest only to those on the Ports Management team.
Most of the package building magic occurs under the /var/portbuild directory. Unless otherwise specified, all paths will be relative to this location. ${arch} will be used to specify one of the package architectures (amd64, i386™, ia64, powerpc, and SPARC64®), and ${branch} will be used to specify the build branch (7, 7-exp, 8, 8-exp, 9, 9-exp).
Note: Packages are no longer built for Releases 4, 5, or 6, nor for the alpha architecture.
The scripts that control all of this live in /var/portbuild/scripts/. These are the checked-out copies from /usr/ports/Tools/portbuild/scripts/.
Typically, incremental builds are done that use previous packages as dependencies; this takes less time, and puts less load on the mirrors. Full builds are usually only done:
right after release time, for the -STABLE branches
periodically to test changes to -CURRENT
for experimental builds
Until mid-2010, the scripts were completely specific to pointyhat as the head (dispatch) node. During the summer of 2010, a significant rewrite was done in order to allow for other hosts to be head nodes. Among the changes were:
removal of the hard-coding of the string pointyhat
factoring out all configuration constants (which were previously scattered throughout the code) into configuration files (see below)
appending the hostname to the directories specified by buildid (this will allow directories to be unambigious when copied between machines.)
making the scripts more robust in terms of setting up directories and symlinks
where necessary, changing certain script invocations to make all the above easier
This document was originally written before these changes were made. Where things such as script invocations have changed, they are denoted as new codebase: as opposed to old codebase:.
Note: As of December 2010, pointyhat is still running on the old codebase, until the new codebase is considered rock-solid.
