Antoine Musso 20cf8d5e70 project matrix: rename variable/refactor
While reviewing the YAML axis execution strategy for the matrix project,
Darragh Bailey suggested to:

* use proper variable naming
* JJB exceptions
* Rely on hudson_model
* Drop trailing slashes

Slightly refactor the matrix project method.

For the combination touchstones, the web interface list the result has
'Stable', 'Unstable'.  Map 'Stable' to 'Success' which is actually in
hudson.model.Result.  Add a basic test to cover that.

"""
The matrix project module handles creating Jenkins matrix
projects. To create a matrix project specify ``matrix`` in the
``project-type`` attribute to the :ref:`Job` definition.
Currently it supports four axes which share the same
internal YAML structure:
* label expressions (``label-expression``)
* user-defined values (``user-defined``)
* slave name or label (``slave``)
* JDK name (``jdk``)
Requires the Jenkins :jenkins-wiki:`Matrix Project Plugin
<Matrix+Project+Plugin>`.
The module also supports additional, plugin-defined axes:
* DynamicAxis (``dynamic``), requires the Jenkins
:jenkins-wiki:`DynamicAxis Plugin <DynamicAxis+Plugin>`
* GroovyAxis (``groovy``), requires the Jenkins
:jenkins-wiki:`GroovyAxis Plugin <GroovyAxis>`
* YamlAxis (``yaml``), requires the Jenkins
:jenkins-wiki:`Yaml Axis Plugin <Yaml+Axis+Plugin>`
To tie the parent job to a specific node, you should use ``node`` parameter.
On a matrix project, this will tie *only* the parent job. To restrict axes
jobs, you can define a single value ``slave`` axis.
:Job Parameters:
.. note::
You can only pick one of the strategies.
* **execution-strategy** (optional, built in Jenkins):
* **combination-filter** (`str`): axes selection filter
* **sequential** (`bool`): run builds sequentially (default false)
* **touchstone** (optional):
* **expr** (`str`) -- selection filter for the touchstone build
* **result** (`str`) -- required result of the job: \
stable (default) or unstable
* **yaml-strategy** (optional, requires
:jenkins-wiki:`Yaml Axis Plugin <Yaml+Axis+Plugin>`):
* **exclude-key** (`str`) -- top key containing exclusion rules
* Either one of:
* **filename** (`str`) -- Yaml file containing exclusions
* **text** (`str`) -- Inlined Yaml. Should be literal
``text: | exclude:...``
* **axes** (`list`):
* **axis**:
* **type** (`str`) -- axis type, must be either type defined by
:jenkins-wiki:`Matrix Project Plugin <Matrix+Project+Plugin>`
(``label-expression``, ``user-defined``, ``slave`` or ``jdk``) or
a type defined by a plugin (see top of this document for a list
of supported plugins).
* **name** (`str`) -- name of the axis
* **values** (`list`) -- values of the axis
The module supports also ShiningPanda axes:
Example:
.. literalinclude:: /../../tests/general/fixtures/matrix-axis003.yaml
Requires the Jenkins :jenkins-wiki:`ShiningPanda Plugin <ShiningPanda+Plugin>`.
Example:
.. literalinclude:: /../../tests/yamlparser/fixtures/project-matrix001.yaml
:language: yaml
Examples for yaml axis:
.. literalinclude:: /../../tests/general/fixtures/matrix-axis-yaml.yaml
:language: yaml
.. literalinclude::
/../../tests/general/fixtures/matrix-axis-yaml-strategy-file.yaml
:language: yaml
.. literalinclude::
/../../tests/general/fixtures/matrix-axis-yaml-strategy-inlined.yaml
:language: yaml
