Hi All:
I'd like to tie up a loose end with callers of AbstractConfiguration.
AbstractConfiguration(LoggerContext, ConfigurationSource)
There are four call sites that do this:
super(null, ConfigurationSource.NULL_SOURCE);
These are:
-
org.apache.logging.log4j.core.BasicConfigurationFactory.BasicConfiguration.BasicConfiguration()
-
org.apache.logging.log4j.core.config.DefaultConfiguration.DefaultConfiguration()
- org.apache.logging.log4j.core.config.NullConfiguration.NullConfiguration()
-
org.apache.logging.log4j.core.config.composite.CompositeConfiguration.CompositeConfiguration(List<?
extends AbstractConfiguration>)
I am worried about this last one.
So I cannot null check the logger context in the AbstractConfiguration ctor:
protected AbstractConfiguration(LoggerContext loggerContext, final
ConfigurationSource configurationSource) {
this.loggerContext = new WeakReference<>(loggerContext);
// The loggerContext is null for the NullConfiguration class.
// this.loggerContext = new
WeakReference(Objects.requireNonNull(loggerContext, "loggerContext is
null"));
this.configurationSource =
Objects.requireNonNull(configurationSource, "configurationSource is null");
...
}
There are a couple of call sites where we could pass in a LC but we'd need
to add the LC to ctor for classes listed above. The default configs usually
include just console logging, but is that straight to the console or via a
ConsoleAppender?
I could even see adding a ctor
AbstractConfiguration.AbstractConfiguration(NullConfiguration)
to make it obvious that this is the only way is OK to pass null for the
logger context. Then the NullConfiguration ctor does not need to pass null.
Thoughts?
