Today we force indices that were created with N-2 and older versions of Lucene
to fail on open. This check doesn't even check if the codecs are available. In order
to allow users to open older indices and for us to support N-2 versions this change
adds an API on DirectoryReader to specify a minimum index version on a per reader basis.
This doesn't apply for the IndexWriter which will fail on opening older indices.
Prior to this commit, SuggestComponent used a HashMap as part of the
response it built on the server side. This class is serialized/
deserialized differently depending on the SolrJ ResponseParser used:
a LinkedHashMap when javabin was used, and a SimpleOrderedMap when XML
was used. This discrepancy led to ClassCastException's in downstream
SolrJ code.
This commit fixes the issue by changing SuggestComponent to avoid these
types that are serialized differently. "suggest" response sections now
deserialize as a NamedList in SolrJ, and the SuggesterResponse POJO has
been updated accordingly.
This ensures all derefernced fields are not parsed into actual valuesource
but parsed into a placeholder value. This works for 1-level of dereferencing
* When the schema defines _root_, and you want to do atomic/partial updates...
** _root_ needn't be stored or have docValues any more
** _nest_path_ field isn't needed for this any more
** Simplified internal logic
* Allow (and recommend, eventually insist) that the _root_ field be passed for atomic/partial updates to child docs.
** In the absence of _root_, assume the _route_ param is equivalent to ameliorate back-compat scope. This is a temporary hack; remove in SOLR-15064.
** One of the two is required; you'll get an exception if the assumption is false. THIS IS A BACK-COMPAT CHANGE
* Ensure that the update log contains the _root_ field if it's defined in the schema; in some cases it wasn't. It's important for robustness of atomic/partial updates to child docs. Caveat: the buffer replay scenario is not tested with child docs.
* Limited the cases when a realtime searcher is re-opened. It was being applied to any update that included child docs but now only some narrow subset: only for atomic/partial updates, and when the update log contains an in-place update for the same nest because it's complicated to resolve those log entries.
* Internal improvements to RealTimeGetComponent to aid clarity & robustness & probably performance...
** Use SolrDocumentFetcher.solrDoc(docID, ReturnFields) instead of more manual loading. Will do more with this in another PR.
** Clarify when only root doc IDs are expected.
** Use Resolution enum more, add PARTIAL, remove DOC_WITH_CHILDREN; enhance docs.
** When have ReturnFields, a Set of "onlyTheseFields" becomes redundant. Add a child doc resolution via a transformer when needed.
** Clarified where copy-field targets are removed
* NestPathField should default to single valued, instead of inheriting the schema default, which for ancient schemas was multi-valued.
* AddUpdateCommand.getLuceneDocument(s) methods are very internal; made package visible and refactored a bit for clarity
* DocumentBuilder: when in-place update, skip id and _root_ here, thus also simplifying further logic
* NestedShardedAtomicUpdateTest no longer extends AbstractFullDistribZkTestBase because it wasn't really leveraging the "control client" checking, and it added too much complexity to debug failures.
missing, allBuckets, and numBuckets is not supported with stream method.
So, avoiding picking stream method when any one of them is enabled even if
facet sort is 'index asc'
CopyFields are regenerated in case of replace-field or replace-field-type.
While regenerating, source and destionation are checked against fields but source/dest
could match dynamic rule too.
For example,
<copyField source="something_s" dest="spellcheck"/>
<dynamicField name="*_s" type="string"/>
here, something_s is not present in schema but matches the dynamic rule.
To handle the above case, need to check dynamicFieldCache too while regenerating the
copyFields
Return proper error code on invalid value with in-place update.
Handle invalid value for inc op with the in-place update, uses toNativeType to convert increment value instead of direct parsing. Also, return an error when inc operation is specified for the non-numeric field
SOLR-13027 Use TestInjection so that we always have a Tragic Event
When we encounter a tragic error in the index writer, we can trigger a
leader election instead of queing up a delete and re-add of the node in
question. This should result in a more graceful transition, and the
previous leader will eventually be put into recovery by a new leader.
closes#2120
Prior to this change, it was not feasible to write a custom aggregate function in plugin code
because the FacetContext class did not expose its fields for access outside its package. Also
some of the useful abstract classes for SlotAcc were package-private too
Adds two metrics to the SolrCloud Overseer: solr_metrics_overseer_stateUpdateQueueSize and solr_metrics_overseer_collectionWorkQueueSize with corresponding entries in the the Prometheus exporter's default/stock configuration.

This addresses review feedback from David Smiley on Jira. It moves the request registration to the ContentStreamHandlerBase class instead of doing a hack-ish instanceof check inside HttpSolrCall.
