(logging-log4j2) 01/01: Generalize DI usage
Posted by pk...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
pkarwasz pushed a commit to branch fix/generalize-di-usage
in repository https://gitbox.apache.org/repos/asf/logging-log4j2.git
commit 536df2aa1c078f82516e8a70d6e67e1d7b45f1a8
Author: Piotr P. Karwasz <pi...@karwasz.org>
AuthorDate: Mon Mar 4 13:12:25 2024 +0100
Generalize DI usage
This commit ensures that:
* an `InstanceFactory` is created in the Log4j `Provider`,
* the same factory is injected as parameters to all
the components of the chain `Log4jContextFactory`, `ContextSelector`,
`LoggerContext` (child), `Configuration` (grand-child).
* `DI.createInstanceFactory` is called only when strictly necessary.
