## Requirements

### Server

 * A posix like shell
 * Python (>= 3.2 required)
 * SSH client
 * Asciidoc (for building the manpages)

### Client ("target host")

 * A posix like shell
 * SSH server


## Installation

### Preparation

Ensure you have Python 3.2 installed on the machine you use to **deploy to the targets**
(the ***source host***).

#### Archlinux

Archlinux already has python >= 3.2, so you only need to do:

    pacman -S python

#### CentOS

See the "From source" section

#### Debian

For Debian >= wheezy:

    aptitude install python3

On squeeze you can add following line in **/etc/apt/sources.list**

  deb http://ftp.debian.org/debian wheezy main

And add pinning entry in **/etc/apt/preferences.d/wheezy**:

  Package: *
  Pin: release n=wheezy
  Pin-Priority: 1

Please be aware that both **openssh-server** and **openssh-client** might be
removed on **python3.2** installation. You surely want to reinstall them:

  apt-get install -t wheezy openssh-server openssh-client

For older Debian versions, installing python 3.2 manually is required.


#### Fedora

For Fedora >= 15:

    yum install python3

#### FreeBSD

For the port:

    cd /usr/ports/lang/python32/ && make install clean

For the package:

    pkg_add -r python32

#### Gentoo

Gentoo only provides python 3.2 in testing packages (http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=3&chap=3).
If you want to ensure nothing breaks you must set back the python version to what was default before.

    emerge -av =python-3.2.2 --autounmask-write
    emerge -av =python-3.2.2
    eselect python list
    eselect python list set python3.2

#### Max OS X

You can choose between Homebrew and Macports, either way works:

[Homebrew](http://mxcl.github.com/homebrew/) variant:

    brew install python3

[Macports](http://www.macports.org/install.php) variant:

    port install python32
    ln -s /opt/local/bin/python3.2 /opt/local/bin/python3

#### From Source

For those operating systems not yet support Python 3.2:

    pyversion=3.2.3
    wget http://www.python.org/ftp/python/$pyversion/Python-${pyversion}.tar.bz2
    tar xvfj Python-${pyversion}.tar.bz2
    cd Python-${pyversion}
    ./configure
    make
    sudo make install

This installs python 3.2 to /usr/local/bin. Ensure this directory is in
your PATH environment variable.


### Get cdist

You can clone cdist from git, which gives you the advantage of having
a version control in place for development of your own stuff as well.
To install cdist, execute the following commands:

    git clone git://git.schottelius.org/cdist
    cd cdist
    export PATH=$PATH:$(pwd -P)/bin

    # If you want the manpages
    ./build man
    export MANPATH=$MANPATH:$(pwd -P)/doc/man


### Available versions

There are at least the following branches available:

 * Development: master
 * 2.0: Python rewrite of cdist core [stable branch]

Old versions:

 * 1.7: Bugfixes, cleanups, new type and explorer rename
 * 1.6: New types, cleaned up \_\_package* types, internal cleanup
 * 1.5: Focus on object orientation instead of global stage orientation
 * 1.4: Support for redefiniton of objects (if equal)
 * 1.3: Support for local and remote code execution (current stable)
 * 1.2: Dependencies supported
 * 1.1: \_\_file to \_\_file, \_\_directory, \_\_link migration
 * 1.0: First official release

Other branches may be available for features or bugfixes, but they
may vanish at any point. To select a specific branch use

    # Generic code
    git checkout -b <name> origin/<name>
    
    # Stay on a specific version
    version=2.0
    git checkout -b $version origin/$version

### Mirrors

 * git://github.com/telmich/cdist.git ([github](https://github.com/telmich/cdist))
 * git://git.code.sf.net/p/cdist/code ([sourceforge](https://sourceforge.net/p/cdist/code))

## Update

To upgrade cdist in the current branch use

    git pull

    # Also update the manpages
    ./build man
    export MANPATH=$MANPATH:$(pwd -P)/doc/man

If you stay on a version branche (i.e. 1.0, 1.1., ...), nothing should break.
The master branch on the other hand is the development branch and may not be
working, break your setup or eat the tree in your garden.

### Upgrading from 1.7 to 2.0

* Ensure python (>= 3.2) is installed on the server
* Use "cdist config host" instead of "cdist-deploy-to host"
* Use "cdist config -p host1 host2" instead of "cdist-mass-deploy"
* Use "cdist banner" for fun
* Use **\_\_object_fq** instead of **\_\_self** in manifests

### Upgrading from 1.6 to 1.7

* If you used the global explorer **hardware_type**, you need to change
  your code to use **machine** instead.

### Upgrading from 1.5 to 1.6

* If you used **\_\_package_apt --preseed**, you need to use the new
  type **\_\_debconf_set_selections** instead.
* The **\_\_package** types accepted either --state deinstalled or
  --state uninstaaled. Starting with 1.6, it was made consistently
  to --state removed.

### Upgrading from 1.3 to 1.5

No incompatiblities.

### Upgrading from 1.2 to 1.3

Rename **gencode** of every type to **gencode-remote**.

### Upgrading from 1.1 to 1.2

No incompatiblities.

### Upgrading from 1.0 to 1.1

In 1.1 the type **\_\_file** was split into **\_\_directory**, **\_\_file** and
**\_\_link**. The parameter **--type** was removed from **\_\_file**. Thus you
need to replace **\_\_file** calls in your manifests:

 * Remove --type from all \_\_file calls
 * If type was symlink, use \_\_link and --type symbolic
 * If type was directory, use \_\_directory
