* passing sanity - docs incomplete

* adjusted parameter name

* adjusted unit tests for mode=new

* adjusted integration tests for mode=new

* added 'russoz' to list of maintainers for cpanm

* Update tests/integration/targets/cpanm/tasks/main.yml

* Update tests/integration/targets/cpanm/tasks/main.yml

* ensuring backward compatibility + tests

* added changelog fragment

* version for new parameter and adjusted example

* Update plugins/modules/packaging/language/cpanm.py

Co-authored-by: Felix Fontein <felix@fontein.de>

* multiple changes

- some fixes from PR
- supporting tests
- integration is no longer unsupported => destructive, should run on
  apt- and rpm-based systems only

* only run integration tests in redhat-family > v7 or debian-family

module: cpanm
short_description: Manages Perl library dependencies.
description:
- Manage Perl library dependencies using cpanminus.
options:
name:
type: str
description:
- The Perl library to install. Valid values change according to the I(mode), see notes for more details.
- Note that for installing from a local path the parameter I(from_path) should be used.
aliases: [pkg]
from_path:
type: path
description:
- The local directory or C(tar.gz) file to install from.
notest:
description:
- Do not run unit tests.
type: bool
default: no
locallib:
description:
- Specify the install base to install modules.
type: path
mirror:
description:
- Specifies the base URL for the CPAN mirror to use.
type: str
mirror_only:
description:
- Use the mirror's index file instead of the CPAN Meta DB.
type: bool
default: no
installdeps:
description:
- Only install dependencies.
type: bool
default: no
version:
description:
- Version specification for the perl module. When I(mode) is C(new), C(cpanm) version operators are accepted.
type: str
system_lib:
description:
- Use this if you want to install modules to the system perl include path. You must be root or have "passwordless" sudo for this to work.
- This uses the cpanm commandline option C(--sudo), which has nothing to do with ansible privilege escalation.
- >
This option is not recommended for use and it will be deprecated in the future. If you need to escalate privileges
please consider using any of the multiple mechanisms available in Ansible.
type: bool
default: no
aliases: ['use_sudo']
executable:
description:
- Override the path to the cpanm executable.
type: path
mode:
description:
- Controls the module behavior. See notes below for more details.
type: str
choices: [compatibility, new]
default: compatibility
version_added: 3.0.0
name_check:
description:
- When in C(new) mode, this parameter can be used to check if there is a module I(name) installed (at I(version), when specified).
type: str
version_added: 3.0.0
notes:
- Please note that U(http://search.cpan.org/dist/App-cpanminus/bin/cpanm, cpanm) must be installed on the remote host.
- "This module now comes with a choice of execution I(mode): C(compatibility) or C(new)."
- "C(compatibility) mode:"
- When using C(compatibility) mode, the module will keep backward compatibility. This is the default mode.
- I(name) must be either a module name or a distribution file.
- >
If the perl module given by I(name) is installed (at the exact I(version) when specified), then nothing happens.
Otherwise, it will be installed using the C(cpanm) executable.
- I(name) cannot be an URL, or a git URL.
- C(cpanm) version specifiers do not work in this mode.
- "C(new) mode:"
- "When using C(new) mode, the module will behave differently"
- >
The I(name) parameter may refer to a module name, a distribution file,
a HTTP URL or a git repository URL as described in C(cpanminus) documentation.
- C(cpanm) version specifiers are recognized.
