# 1 Introduction

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 in this article will be of interest only to those on the Ports Management team.

## 1.1 The codebase

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, 10, 10-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 the Subversion repository `base/projects/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

## 1.2 Notes on the codebase

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.

> Note: Also during this process, the codebase was migrated to the Subversion repository. For reference, the previous version may still be found in CVS.
