| 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. | |
