ReconfigureOnChangeFilter should re-use substition properties from initial
configuration
----------------------------------------------------------------------------------------
Key: LBCLASSIC-310
URL: http://jira.qos.ch/browse/LBCLASSIC-310
Project: logback-classic
Issue Type: Improvement
Components: joran
Affects Versions: 0.9.27
Reporter: Gunnar Wagenknecht
Assignee: Logback dev list
Logback configuration files are automatically reloaded when {{scan="true"}} is
set. This is implemented using {{ReconfigureOnChangeFilter}}. The actually
re-configuration happens in {{ReconfiguringThread}} which always creates a new
default {{JoranConfigurator}}.
This is works as long as the initial {{JoranConfigurator}} hasn't been extended
to support additional substitution properties.
{code:java}
// create our customized configurator
final JoranConfigurator configurator = new JoranConfigurator() {
@Override
protected void addImplicitRules(final Interpreter interpreter) {
super.addImplicitRules(interpreter);
// set some properties for log file substitution
if (null != instanceLogfileDirectory) {
interpreter.getInterpretationContext().addSubstitutionProperty("my.property",
calculateMyPropertyValue());
}
}
};
{code}
It should somehow be possible to inherit the custom substitution properties
into the new {{JoranConfigurator}}. Otherwise they are lost on re-configuration.
