==========================
Nico Schottelius <nico-cdist--@--schottelius.org>
NAME
----
cdist-type__package_pip - Manage packages with pip
DESCRIPTION
-----------
Pip is used in Python environments to install packages.
It is also included in the python virtualenv environment.
REQUIRED PARAMETERS
-------------------
state::
Either "present" or "absent".
OPTIONAL PARAMETERS
-------------------
name::
If supplied, use the name and not the object id as the package name.
pip::
Instead of using pip from PATH, use the specific pip path.
EXAMPLES
--------
--------------------------------------------------------------------------------
# Install a package
__package_pip pyro --state present
# Use pip in a virtualenv located at /root/shinken_virtualenv
__package_pip pyro --state present --pip /root/shinken_virtualenv/bin/pip

__typename /foo/bar/ # trailing slash will be stripped, can be documented
__typename /foo//bar//baz # // will be converted to / implicitly through fs; error prone; disallow
require="__a//b//c" __typename # // will be converted to / implicitly through fs; error prone; disallow
Solution:
1) allow require __a//b: type __a, object id /b
=> strip first slash of object id, as we do in non-dep-mode
2) allow _one_ trailing /: __type /foo/bar/ and require="__foo/abc/"
=> strip one leading slash of object id
3) disallow // within object id
4) disallow starting or ending / after 1) and 2)

HOW TO SUBMIT A NEW TYPE
------------------------
For detailled information about types, see cdist-type(7).
Submitting a type works as described above, with the additional requirement
that a corresponding manpage named man.text in asciidoc format with
the manpage-name "cdist-type__NAME" is included in the type directory
AND asciidoc is able to compile it (i.e. do NOT have to many "=" in the second
line).
Warning: Submitting "exec" or "run" types that simply echo their parameter in
gencode* will not be accepted, because they are of no use. Every type can output
code and thus such a type introduces redundant functionality that is given by
core cdist already.

Description:
Type that supports transfer of huge data, which is a general problem in
configuration management systems.
Good solution using standardised rsync approach.
Problem:
Uses root@$__target_host:$destination notation for transfer.
This breaks the concept of being able to replace __remote_exec and
__remote_copy and then doing chroot or different stuff.
This breaks for instance, if __remote_copy = cp and the destination is
a local chroot.
Solutions:
- Have cdist provide support for rsync syntax?
- Integrate __rsyncer more in line with philosohpy of other components
- Think about the general way of __rsyncer and what cdist would need
to provide for general solution.

cdist-type__rsyncer(7)
======================
Daniel Maher <phrawzty+cdist at gmail.com>
NAME
----
cdist-type__rsyncer - Use rsync to copy files.
DESCRIPTION
-----------
This type is used to trigger rsync to copy files from the machine running cdist
(source) to the target machine in question (destination). The likely usage is
the rapid deployment of full directory trees, the cohorency of which can be
guarunteed with the optional --delete argument, which will remove any files
from the destination which are not present on the source.
REQUIRED PARAMETERS
-------------------
source::
The full path of the source from which to copy. This is passed directly
to rsync.
OPTIONAL PARAMETERS
-------------------
destination::
The full path of the destination. This is passed directly to rsync.
Default: object_id
delete::
If true, remove files from destination which are not in source. This is
effectively the --delete argument of rsync.
Default: false
rsyncbin::
Specify the full path to the rsync binary.
Default: `which rsync`
EXAMPLES
--------
--------------------------------------------------------------------------------
# Basic example
__rsyncer '/home/foo' --source '/opt/dist/foo'
# Fancier example
__rsyncer FOO --source '/opt/dist/foo' --destination '/home/foo/' --delete true
