Description

If the current ncf version is used on pre-3.6 CFEngine versions, it fails as the template_method attribute does not exist yet.

We should offer a way to offer this method without breaking old CFEngines!

Note, a workaround exists to solve the problem temporary until it is fixed upstream:

rm /usr/share/ncf/tree/30_generic_methods/file_from_template*
rm /var/rudder/ncf/common/30_generic_methods/file_from_template*
curl https://raw.githubusercontent.com/Normation/ncf/0efb9eb11191fdf31ebb6fba1f4c3a338d925e45/tree/30_generic_methods/file_from_template.cf > /usr/share/ncf/tree/30_generic_methods/file_from_template.cf

Updated by Benoît PECCATTE over 9 years ago

Status changed from 8 to In progress
Target version set to 0.x

First define a new optional attribute to ncf bundles: @agent_version that defines the agent version compatible with this bundle. Currently only >=x.y will be supported.

Then create a shell script that list all .cf files compatible with a given cf-agent version.
This script will be used in body common control to include compatible methods only.

Finally rewrite file_from_template_* to separate 3.5 version and 3.6 version (with mustache suport) and add @agent_version to them.
