Dan Smith reassigned GEODE-716:
-------------------------------
Assignee: Dan Smith
> Race in AttributesMutator.setCacheLoader on partitioned regions can result in
> buckets without a loader
> ------------------------------------------------------------------------------------------------------
>
> Key: GEODE-716
> URL: https://issues.apache.org/jira/browse/GEODE-716
> Project: Geode
> Issue Type: Bug
> Reporter: Dan Smith
> Assignee: Dan Smith
>
> AttributesMutator.setCacheLoader ends up invoking this code in
> PartitionedRegionDataStore.cacheLoaderChanged.
> {code}
> visitBuckets(new BucketVisitor() {
> @Override
> public void visit(Integer bucketId, Region r) {
> AttributesMutator mut = r.getAttributesMutator();
> if (logger.isDebugEnabled()) {
> logger.debug("setting new cache loader in bucket region: {}",
> newLoader);
> }
> mut.setCacheLoader(newLoader);
> }
> });
> {code}
> However, that can miss buckets that are currently being created, because they
> read the existing value for cache loader first, and then later are added to
> localBucket2RegionMap - see PartitionedRegionDataStore.grabFreeBuckets.
> The net result is that some buckets can end up with null for the cache
> loader. If gets a routed to those buckets, they will not invoke the cache
> loader.
