[PAX-LOGGING] Log4J2 status

[Grzegorz Grzybek]

Hello

I'm proud to share the information that all my planned integration tests pass!

I'll do last polishes, talk to Jean Baptiste Onofre tomorrow and I'll think about releasing 1.11.0.CR1. Please check up-to-date https://github.com/ops4j/org.ops4j.pax.logging/tree/master-improvements branch (still not merged with master).

The readme.adoc grew too big - I'll try to change it to manual at some point. And to confluence wiki.

With Log4j2 I'm most satisfied:

 - fragment sample contains @Plugin-s for filters, appenders and trigger policies

 - there are tests using XML and properties syntax

 - there are tests showing restarts and refreshes (just as with Log4J1 and Logback)

 - the tests show that all 3 "backends" work very very consistently wrt configuration, EventAdmin integration, synchronization, OSGIPaxLoggingManager integration, fallback/default logger integration and switching between logging backends without a need to get Logger instance again

 - the most important thing (IMO) is that ALL 11 (*eleven*) ways to print a log work exactly the same. All the below use single backend, single layout and consistent location info detection (previously, %C/%F/%L didn't work for direct use of org.osgi.service.log.LogService)

@Inject
private org.osgi.service.log.LogService osgiLogService;
@Inject
private org.knopflerfish.service.log.LogService fishLogService;

// 1. SLF4j
org.slf4j.LoggerFactory.getLogger(name).info("INFO using SLF4J");

// 2. Commons Logging
org.apache.commons.logging.LogFactory.getLog(name).info("INFO using Commons Logging");

// 3. JULI Logging
org.apache.juli.logging.LogFactory.getLog(name).info("INFO using Juli Logging");

// 4. Avalon Logging
org.ops4j.pax.logging.avalon.AvalonLogFactory.getLogger(name).info("INFO using Avalon Logging");

// 5. JBoss Logging
org.jboss.logging.Logger.getLogger(name).info("INFO using JBoss Logging");

// 6. Knopflerfish - no special facade
fishLogService.log(LogService.LOG_INFO, "INFO using Knopflerfish");

// 7. Log4J1
org.apache.log4j.Logger.getLogger(name).info("INFO using Log4Jv1");

// 8. Logback - only behind SLF4J
//

// 9. Log4J2
org.apache.logging.log4j.LogManager.getLogger(name).info("INFO using Log4Jv2");

// 10. JUL - extra handling without a pax-logging specific facade and shadowing. Only handler redirection
java.util.logging.Logger.getLogger(name).info("INFO using java.util.logging");

// 11. OSGi
osgiLogService.log(LogService.LOG_INFO, "INFO using LogService");

// 12. PaxLoggingService itself
ServiceReference<org.ops4j.pax.logging.PaxLoggingService> sr = context.getServiceReference(org.ops4j.pax.logging.PaxLoggingService.class);
org.ops4j.pax.logging.PaxLoggingService loggingService = context.getService(sr);
loggingService.log(LogService.LOG_INFO, "INFO using PaxLoggingService");
