Allow ConfigInstaller to perform placeholder substitution from framework
properties
-----------------------------------------------------------------------------------
Key: FELIX-2663
URL: https://issues.apache.org/jira/browse/FELIX-2663
Project: Felix
Issue Type: Improvement
Components: File Install
Affects Versions: fileinstall-3.0.2
Reporter: David Hay
The ConfigInstaller class will perform placeholder substitution using
configuration values defined elsewhere in the .cfg file or using System
properties. Would be nice if it could also use properties defined by the
framework (i.e. BundleContext.getProperty())
The use case is this: As part of the OSGi framework initialization, some
properties are set on the framework that define things such as a "home"
directory. The various configuration files could then refer to resources
relative to this "home" directory. For example:
props.setProperty("app.home", homeDir); // homeDir provided by JNDI config, env
variable, etc.
frameworkFactory.newFramework(props);
...
Then, in a configuration file read by the FileInstall bundle, it would be nice
to be able to do:
data.directory=${app.home}/data/
