Mohit Arora updated SLING-9030:
-------------------------------
Description:
[SimpleDistributionAgentQueueProcessor.java|https://github.com/apache/sling-org-apache-sling-distribution-core/blob/master/src/main/java/org/apache/sling/distribution/agent/impl/SimpleDistributionAgentQueueProcessor.java#L83]
is responsible for processing a queueItem which is then passed on to
[RemoteDistributionPackageImporter#importPackage()|https://github.com/apache/sling-org-apache-sling-distribution-core/blob/master/src/main/java/org/apache/sling/distribution/packaging/impl/importer/RemoteDistributionPackageImporter.java#L59]
which in turn selects a valid transporter and send the POST request through
[SimpleHttpDistributionTransport#deliverPackage()|https://github.com/apache/sling-org-apache-sling-distribution-core/blob/master/src/main/java/org/apache/sling/distribution/transport/impl/SimpleHttpDistributionTransport.java#L108].
There can be 2 types of exceptions thrown by this deliverPackage() function.
One is a
[RecoverableDistributionException|https://github.com/apache/sling-org-apache-sling-distribution-core/blob/master/src/main/java/org/apache/sling/distribution/common/RecoverableDistributionException.java]
which is a type of DistributionException and another is DistributionException.
As the name suggests, a RecoverableDistributionException is where the transport
is tried again. But it seems there is currently no cap on the number of retries.
For example, if the endpoint is not accessible at the moment, the error logs of
the caller application will be flooded with constant retries of the
DistributionPackages in queue, until the endpoint comes up and the distribution
is successful. The reason being, [the verbose logging done
here|https://github.com/apache/sling-org-apache-sling-distribution-core/blob/master/src/main/java/org/apache/sling/distribution/agent/impl/SimpleDistributionAgentQueueProcessor.java#L151].
This would lead to sharp increase in disk size of the caller application.
Perhaps the logging can be less verbose and can be logged at *WARN* level for
RecoverableDistributionException.

does not distinguish between a RecoverableDistributionException and a normal
DistributionException. This would lead to sharp increase in disk size of the
caller application. Perhaps the logging can be less verbose and can be logged
at *WARN* level for RecoverableDistributionException.
