Patrick Rhomberg resolved GEODE-4902.
-------------------------------------
Resolution: Fixed
> Log markers filter some messages pathologically
> -----------------------------------------------
>
> Key: GEODE-4902
> URL: https://issues.apache.org/jira/browse/GEODE-4902
> Project: Geode
> Issue Type: Bug
> Components: docs, logging
> Reporter: Patrick Rhomberg
> Assignee: Patrick Rhomberg
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.6.0
>
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> Many logging calls across all log levels are marked with
> {{o.a.g.internal.logging.log4j.LogMarker}} markers for selective enabling and
> debugging. All these markers have a parent marker {{GEODE_VERBOSE}}.
> However, per the default given in
> {{geode-core/src/main/resources/log4j2.xml}}, this parent marker is set to
> filter log messages.
> Many of these log messages are invoked at the {{info}} level, suggesting an
> expectation that the message would be seen.
> These markers should be refactored to (a) include by default markers that
> commonly or exclusively appear in coarse-grained logging levels, and (b) to
> reorganize the markers' parent/child relationships so that they are not
> blanket-disabled by default. Only those markers attacked to more verbose
> logging should be disabled by default.
> ---
> Additionally, the log classes {{FastLogger}} and {{LogWriterLogger}} are
> themselves slightly pathological. Notably, the former overrides some
> {{isEnabled}} aliases but leaves exposed default many of the root method
> signatures. The latter pathologically includes a reference to itself as a
> field unto itself in the lines:
> {noformat}
> private final ExtendedLoggerWrapper logWrapper;
> // ...
> private LogWriterLogger(final Logger logger, final String connectionName,
> final boolean isSecure) {
> super((AbstractLogger) logger, logger.getName(),
> logger.getMessageFactory());
> this.logWrapper = this;
> // ...
> }
> {noformat}
> These classes could use refactoring in their own right, perhaps as a separate
> child ticket.
> ---------
> Docs: While only the top-level marker (formerly {{GEMFIRE_VERBOSE}}, now
> {{GEODE_VERBOSE}}) is documented, it may be worth a release note that the
> Log4J2 markers have changed, and anyone be using a custom log4j2.xml after
> discovering these markers will have to update that XML to the new markers.
