-----------------------------------
Summary: Add plugin/bean scopes to unify object lifecycle
management APIs
Key: LOG4J2-2852
URL: https://issues.apache.org/jira/browse/LOG4J2-2852
Project: Log4j 2
Issue Type: Task
Components: Core
Reporter: Matt Sicker
In the 2.x plugin API, we implement a sort of ad hoc mechanism for lifecycle
and instance management based on a plugin's category. For example, the "Core"
category of plugins all map to lifecycles of a configuration file with each
instance injected into a particular configuration node or nodes. Other plugins
are created in other scopes, and some other code attempts to emulate singleton
scopes via system properties and other similar indirections.
In 3.0, these APIs should be unified into a singular "scope" concept. This idea
is modeled after the
[Context|https://docs.jboss.org/cdi/api/2.0/javax/enterprise/context/spi/Context.html]
API from CDI. A scope should control the lifecycle of a plugin instance which
can be specified through an annotation. Example scopes that need to be
supported include singleton, logger context, configuration, and dependent. The
singleton and dependent scopes should behave analogously to their CDI contexts.
The logger context and configuration scopes should be bound to the lifecycles
of {{LoggerContext}} and {{Configuration}} respectively.
