This is related to #28898. This commit adds the acceptor thread name to
the method checking if this thread is a transport thread. Additionally,
it modifies the nio http transport to use the same worker name as the
netty4 http server transport.
This is related to #27260. This commit combines the AcceptingSelector
and SocketSelector classes into a single NioSelector. This change
allows the same selector to handle both server and socket channels. This
is valuable as we do not necessarily want a dedicated thread running for
accepting channels.
With this change, this commit removes the configuration for dedicated
accepting selectors for the normal transport class. The accepting
workload for new node connections is likely low, meaning that there is
no need to dedicate a thread to this process.
Currently the engine is initialized with a hardcoded 256MB of RAM. Elasticsearch
may never use more than that for a given shard, `IndexingMemoryController` only
has the power to flush segments to disk earlier in case multiple shards are
actively indexing and use too much memory.
While this amount of memory is enough for an index with few fields and larger
RAM buffers are not expected to improve indexing speed, this might actually be
little for an index that has many fields.
Kudos to @bleskes for finding it out when looking into a user who was reporting
a **much** slower indexing speed when upgrading from 2.x to 5.6 with an index
that has about 20,000 fields.
We currently have a specific REST action to retrieve all indices and types mappings, which used internally the get index API. This doesn't seem to be required anymore though as the existing RestGetMappingAction could as well take the requests with no indices and types specified.
This commit removes the RestGetAllMappingsAction in favour of using RestGetMappingAction also for requests that don't specify indices nor types.
The Index Audit trail allows the override of the template index
settings with settings specified on the conf file.
A bug will manifest when such conf file settings are specified
for templates that need to be upgraded. The bug is an endless
upgrade loop because the upgrade, although successful, is
not reckoned as such by the upgrade service.
move `finger_print`, `pattern` and `standard_html_strip` analyzers
to analysis-common module. (both AnalysisProvider and PreBuiltAnalyzerProvider)
Changed PreBuiltAnalyzerProviderFactory to extend from PreConfiguredAnalysisComponent and
changed to make sure that predefined analyzers are always instantiated with the current
ES version and if an instance is requested for a different version then delegate to PreBuiltCache.
This is similar to the behaviour that exists today in AnalysisRegistry.PreBuiltAnalysis and
PreBuiltAnalyzerProviderFactory. (#31095)

This is related to #28898. This commit adds cors support to the nio http
transport. Most of the work is copied directly from the netty module
implementation. Additionally, this commit adds tests for the nio http
channel.
When the last indexing operation is completed, we will fire a global
checkpoint sync. Since a global checkpoint sync request is a replication
request, it will acquire an index shard permit on the primary when
executing. If this happens at the same time while we are issuing the
synced-flush, the synced-flush request will fail as it thinks there are
in-flight operations. We can avoid such situation by retrying another
synced-flush if the current request fails due to ongoing operations on
the primary.
Closes#29392
This commit adds a new writeBlobAtomic() method to the BlobContainer
interface that can be implemented by repository implementations which
support atomic writes operations.
When the BlobContainer implementation does not provide a specific
implementation of writeBlobAtomic(), then the writeBlob() method is used.

This will be necessary for the `docvalue_fields` option to work correctly once
we use the field's doc-value format to format doc-value fields. Binary values
are formatted as base64-encoded strings.
In spite of the existing caching, I have seen a number of nodes hot threads
where one thread had been spending all its cpu on computing the size of a
directory. I am proposing to move the computation of the size of the directory
to `StoreDirectory` in order to skip recomputing the size of the directory if
no changes have been made. This should help with users that have read-only
indices, which is very common for time-based indices.
Currently this class takes care of moth selecting the relevant value, and
replacing missing values if any. This is fine for sorting, which always needs
to do both at the same time, but we also have a number of aggregations and
script utils that need to retain information about missing values so this change
proposes to decouple selection of the relevant value and replacement of missing
values.
* Fix index prefixes to work with span_multi
Text fields that use `index_prefixes` can rewrite `prefix` queries into
`term` queries internally. This commit fix the handling of this rewriting
in the `span_multi` query.
This change also copies the index options of the text field into the
prefix field in order to be able to run positional queries. This is mandatory
for `span_multi` to work but this could also be useful to optimize `match_phrase_prefix`
queries in a follow up. Note that this change can only be done on indices created
after 6.3 since we set the index options to doc only in this version.
Fixes#31056
ObjectParser should throw XContentParseExceptions, not IAE. A dedicated parsing
exception can includes the place where the error occurred.

This snapshot includes:
- LUCENE-8341: Record soft deletes in SegmentCommitInfo which will resolve#30851
- LUCENE-8335: Enforce soft-deletes field up-front
When `lenient=false`, attempts to create match phrase queries with custom analyzers against non-text fields will throw an IllegalArgumentException.
Also changes `*Match*QueryBuilderTests` so that it avoids this scenario
Fixes#31061
The majority of Responses inheriting from AcknowledgeResponse implement
the readFrom and writeTo serialization method in the same way. Moving this
as a default into AcknowledgeResponse and letting the few exceptions that
need a slightly different implementation handle this themselves saves a lot
of duplication.
Specifying `index_phrases: true` on a text field mapping will add a subsidiary
[field]._index_phrase field, indexing two-term shingles from the parent field.
The parent analysis chain is re-used, wrapped with a FixedShingleFilter.
At query time, if a phrase match query is executed, the mapping will redirect it
to run against the subsidiary field.
This should trade faster phrase querying for a larger index and longer indexing
times.

This commit fixes an issue with
PersistentTasksCustomMetaDataTests#testMinVersionSerialization. There
were two problems here:
- some versions do not have future compatible version (e.g., betas)
- the feature logic was incorrect
With #31020 we introduced the ability for transport clients to indicate what features they support
in order to make sure we don't serialize object to them they don't support. This PR adapts the
serialization logic of persistent tasks to be aware of those features and not serialize tasks that
aren't supported.
Also, a version check is added for the future where we may add new tasks implementations and
need to be able to indicate they shouldn't be serialized both to nodes and clients.
As the implementation relies on the interface of `PersistentTaskParams`, these are no longer
optional. That's acceptable as all current implementation have them and we plan to make
`PersistentTaskParams` more central in the future.

We compute a random version and later try to compute the version prior
that random version. If the random version is the earliest version in
our list of versions then it, by definition, does not have a previous
version. Yet trying to find its previous is someting we do and so the
test fails. This commit adds a version check to the randomization so
that we do not select the earliest version in our list.
This is related to #31017. That issue identified that these three http
methods were treated like GET requests. This commit adds them to
RestRequest. This means that these methods will be handled properly and
generate 405s.
This commit introduces the ability for a client to communicate to the
server features that it can support and for these features to be used in
influencing the decisions that the server makes when communicating with
the client. To this end we carry the features from the client to the
underlying stream as we carry the version of the client today. This
enables us to enhance the logic where we make protocol decisions on the
basis of the version on the stream to also make protocol decisions on
the basis of the features on the stream. With such functionality, the
client can communicate to the server if it is a transport client, or if
it has, for example, X-Pack installed. This enables us to support
rolling upgrades from the OSS distribution to the default distribution
without breaking client connectivity as we can now elect to serialize
customs in the cluster state depending on whether or not the client
reports to us using the feature capabilities that it can under these
customs. This means that we would avoid sending a client pieces of the
cluster state that it can not understand. However, we want to take care
and always send the full cluster state during node-to-node communication
as otherwise we would end up with different understanding of what is in
the cluster state across nodes depending on which features they reported
to have. This is why when deciding whether or not to write out a custom
we always send the custom if the client is not a transport client and
otherwise do not send the custom if the client is transport client that
does not report to have the feature required by the custom.

With the default distribution changing in 6.3, clusters might now contain custom metadata that a
pure OSS transport client cannot deserialize. As this can break transport clients when accessing
the cluster state or reroute APIs, we've decided to exclude any custom metadata that the transport
client might not be able to deserialize. This will ensure compatibility between a < 6.3 transport
client and a 6.3 default distribution cluster. Note that this PR only covers interoperability with older
clients, another follow-up PR will cover full interoperability for >= 6.3 transport clients where we will
make it possible again to get the custom metadata from the cluster state.

This change adds an option named `split_queries_on_whitespace` to the `keyword`
field type. When set to true full text queries (`match`, `multi_match`, `query_string`, ...) that target the field will split the input on whitespace to build the query terms. Defaults to `false`.
Closes#30393
The randomized alias names could contain unicode controll charactes that don't
survive an xContent rendering and parsing roundtrip when using the YAML xContent
type. This fix filters the randomized unicode string for control characters to
avoid this particular problem.
Closes#30911
In case an error is returned when calling search_shards on a remote
cluster, which will lead to throwing an exception in the coordinating
node, we should make sure that the status code returned by the
coordinating node is the same as the one returned by the remote
cluster. Up until now a 500 - Internal Server Error was always
returned. This commit changes this behaviour so that for instance if an
index is not found, which causes an 404, a 404 is also returned by the
coordinating node to the client.
Closes#27461
This commit reworks testing for `ListTasksResponse` so that random
fields insertion can be tested and xcontent equivalence can be checked
too. Proper exclusions need to be configured, and failures need to be
tested separately. This helped finding a little problem, whenever there
is a node failure returned, the nodeId was lost as it was never printed
out as part of the exception toXContent.
This is related to #30141. Right now in the transport client we open a
temporary node connection and take the node information. This node
information is used to open a permanent connection that is used for the
client. However, we continue to use the configured transport address.
If the configured transport address is a load balancer, you might
connect to a different node for the permanent connection. This causes
the handshake validation to fail. This commit removes the handshake
validation for the transport client when it simple node sample mode.
Since master will always communicate with a >=6.4 node, the logic for
checking if the node is 6.4 and conditionally reading and writing based
on that can be removed from master. This logic will stay in 6.x as it is
the bridge to the cleaner response in master. This also unmutes the
failing test due to this bwc change.
