Add basic dependency handling to PackageTrack and PackagerGroup.
PackageTrack now extracts dependency information from the debian/control
file and PackagerGroup sorts the tracks based on this information so
that packages on which other packages in the group depend on are built
first and their newly built binaries are installed added to the pbuilder
instance.
Also add some test cases.

| 42 | 1 README for TreePackager |
| 2 ======================= | |
| 3 | |
| 4 | |
| 5 TreePackager is a tool to automatically build debian packages from SVN. | |
| 6 | |
| 7 | |
| 8 Prerequisites | |
| 9 ------------- | |
| 10 | |
| 11 You need the following software to run TreePackager. In the list below, | |
| 12 parentheses contain the name of the corresponding package in Debian Etch | |
| 13 if its not the same as the software. The version required is usually | |
| 14 the one from debian etch. | |
| 15 | |
| 16 Python 2.4 (python2.4-minimal) | |
| 17 Debian devscripts (devscripts) | |
| 18 subversion | |
| 19 pbuilder | |
| 20 sudo | |
| 21 bzip2 | |
| 22 | |
| 23 For the web front-end you also need the following software: | |
| 24 | |
| 25 Genshi (python-genshi) | |
| 26 CherryPy (python-cherrypy) | |
| 27 | |
| 28 Some of the packagers require additional software. The KDEPIM | |
| 29 enterprise branch packagers require the following additional software: | |
| 30 | |
| 31 autoconf2.13 | |
| 32 automake1.9 | |
| 33 | |
| 34 | |
| 35 Installation | |
| 36 ------------ | |
| 37 | |
| 38 You can run the tree packager itself directly from the source tree. | |
| 39 However, you need to configure it first and setup pbuilder. | |
| 40 | |
| 41 | |
| 42 Configuration | |
| 43 ------------- | |
| 44 | |
| 45 To understand the configuration, first a few notes about the | |
| 46 architecture of TreePackager. The TreePackager consist of one program | |
| 47 that periodically updates svn working directories and if something has | |
| 48 changed, builds a new debian package from the working directory. The | |
| 49 program should run as a normal user. The sample configuration assumes | |
| 50 that it's the user "builder" with a home directory "/home/builder". The | |
| 51 default configuration manages a directory tree under | |
| 52 "/home/builder/enterprise". | |
| 53 | |
| 54 The binary packages are built with pbuilder. Because pbuilder uses a | |
| 55 chroot environment to build the packages, it must be run as root. The | |
| 56 tree packager therefore needs a way to run pbuilder as root even though | |
| 57 itself runs as a non-root user. By default the tree packager uses sudo, | |
| 58 so you have to setup sudo to allow the tree packager user to invoke | |
| 59 pbuilder without a password. This can be accomplished with the | |
| 60 following line in /etc/sudoers (using the default user name): | |
| 61 | |
| 62 builder ALL = NOPASSWD: /usr/sbin/pbuilder | |
| 63 | |
| 64 | |
| 65 Configure TreePackager | |
| 66 ~~~~~~~~~~~~~~~~~~~~~~ | |
| 67 | |
| 68 The file demo.cfg contains example configuration that contains most of | |
| 69 what is needed to package KDEPIM and kde-i18n from the KDEPIM enterprise | |
| 70 branch. Copy this file to treepkg.cfg and adapt it to your needs. The | |

85 corresponding pkg_-section). One thing needed by a packager is the |
| 72 | 86 contents of the debian sub-directory of the debian source package. When |
| 87 creating the source package, the packager simply copies the | |
| 88 sub-directory "debian" of the base_dir into the directory making up the | |
| 89 source tree. How the debian directory is created and maintained is up | |
| 90 to you. Usually it's a good idea to start with the debian sub-directory | |
| 91 an existing debian package for the software. | |
