Adrien Grand updated LUCENE-4876:
---------------------------------
Attachment: LUCENE-4876.patch
New patch:
* Added CHANGES entries
* Added documentation to PersistentSnapshotDeletionPolicy to make clear that
instances of this classes must not be shared across IndexWriters
* Some Solr tests were failing because Solr expects SolrCore.solrDelPolicy to
be the same instance as IndexWriter.getConfig().getIndexDeletionPolicy(). There
is sensible code relying on it (SnapShooter/ReplicationHandler in particular)
so I preferred emulating the old behavior by making
IndexDeletetionPolicyWrapper.clone() return 'this' for the moment. This is not
a problem because each core has its own private deletion policy and never opens
more than one IndexWriter with it.
> IndexWriterConfig.clone should clone the MergeScheduler

> ConcurrentMergeScheduler has a List<MergeThread> member to track the running
> merging threads, so IndexWriterConfig.clone should clone the merge scheduler
> so that both IndexWriterConfig instances are independant.
