Bug fixes
|

|
||||
* LUCENE-8726: ValueSource.asDoubleValuesSource() could leak a reference to
|
||||
IndexSearcher (Alan Woodward, Yury Pakhomov)
|
||||
|
||||
* LUCENE-8735: FilterDirectory.getPendingDeletions now forwards to the delegate
|
||||
even the method is not abstract in the super class. This prevents issues
|
||||
where our best effort in carrying on generations in the IndexWriter since pending
|
||||
deletions are swallowed by the FilterDirectory. (Henning Andersen, Simon Willnauer)
|
||||
|
||||
* LUCENE-8688: TieredMergePolicy#findForcedMerges now tries to create the
|
||||
cheapest merges that allow the index to go down to `maxSegmentCount` segments
|
||||
or less. (Armin Braun via Adrien Grand)
|
||||
|
||||
* LUCENE-8785: Ensure new threadstates are locked before retrieving the number of active threadstates.
|
||||
This causes assertion errors and potentially broken field attributes in the IndexWriter when
|
||||
IndexWriter#deleteAll is called while actively indexing. (Simon Willnauer)
|
||||
|
||||
* LUCENE-8720: NameIntCacheLRU (in the facets module) had an int
|
||||
overflow bug that disabled cleaning of the cache (Russell A Brown)
|
||||
|
||||
* LUCENE-8809: Refresh and rollback concurrently can leave segment states unclosed (Nhat Nguyen)

Versions of Major Components

Carrot2 3.16.0
|

Upgrade Notes
|
||||
----------------------
|
||||
|
||||
* SOLR-13234: The Prometheus Metric Exporter now collects metrics from Solr at a fixed schedule that is controlled
|
||||
by the exporter itself. The default interval is 60s but it can be changed by specifying the --scrape-interval
|
||||
command line parameter to the tool. The collected metrics are cached and returned for any requests coming in before
|
||||
the next scheduled collection. This can impact the freshness of the metrics if prometheus is configured to query the
|
||||
tool more frequently.
|
||||
|
||||
* SOLR-12708: When requesting the status of an async request via REQUESTSTATUS collections API, the response will
|
||||
include the list of internal async requests (if any) in the "success" or "failed" keys (in addition
|
||||
to them being included outside those keys for backwards compatibility). See SOLR-12708 for more
|
||||
details
|
||||
|
||||
Bug fixes
|
||||
----------------------
|
||||
|
||||
* SOLR-13234: Prometheus Metric Exporter not threadsafe. This changes the prometheus exporter to collect metrics
|
||||
from Solr on a fixed interval controlled by this tool and prevents concurrent collections. This change also improves
|
||||
performance slightly by using the cluster state instead of sending multiple HTTP requests to each node to lookup
|
||||
all the cores.
|
||||

* SOLR-12708: Async collection actions should not hide internal failures (Mano Kovacs, Varun Thacker, Tomás Fernández Löbbe)
