[jira] [Resolved] (LOGCXX-560) Logging in a static initializer

["Stephen Webb (Jira)" <lo...@logging.apache.org>]

     [ https://issues.apache.org/jira/browse/LOGCXX-560?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stephen Webb resolved LOGCXX-560.
---------------------------------
    Fix Version/s: 1.0.0
       Resolution: Fixed

I believe the documentation showing how to put initialisation code in a wrapped call to getlogger() is the most appropriate solution.

> Logging needs to be configured before the first log call. To log in a static initializer code, configuration must be executed during static initialization.
> The log4cxx documentation and examples suggest calling the configure method of the selected configurator in the main routine. It does not currently describe automatic configuration. 
> Automatic configuration currently requires either a special name (log4cxx.xxx or log4j.xxx) for the config file or an environment variable (LOG4CXX_CONFIGURATION or log4j.configuration) set with the name of the config file.
> It would be nice to be able to plug in user specified configuration logic that is invoked by log4cxx.
> One possible approach would be to override autoConfigure() (added in [#135)|https://github.com/apache/logging-log4cxx/pull/135] in a class that inherits from log4cxx::Hierarchy.
> Calling the LogManager::setRepositorySelector static function before other static initialisations is difficult as static initialization order is not easily controlled.
> A new static method LogManager::getLogger("name", MyRepository::Instance()) would prevent static initialization order issues.
