Adds allow_partial_search_results flag to search requests with default setting = true.
When false, will error if search either timeouts, has partial errors or has missing shards rather
than returning partial search results. A cluster-level setting provides a default for search requests with no flag.
Closes#27435
This change makes sure that this function does not create field names that end with a '.', more precisely it only allows
alpha-numeric characters to compose the leaf field name.
Closes#27373
The MockUncasedHostProvider accesses nodes that are not fully built yet, where TransportService.getNode() returns null, which means that the null entries end up in the list of seedNodes that UnicastZenPing then uses.
Cluster settings shouldn't leak into the next test.
I played with failing the test if it left over any settings but that
felt like it added more ceremony then it was worth. The advantage is
that any test that intentionally wants to leave settings in place after
the test would fail and require looking at but, so far as I can tell, we
don't have any such tests.
Currently meta plugins will ask for confirmation of security policy
exceptions for each bundled plugin. This commit collects the necessary
permissions of each bundled plugin, and asks for confirmation of all of
them at the same time.

This introduces a settings updater that allows to specify a list of
settings. Whenever one of those settings changes, the whole block of
settings is passed to the consumer.
This also fixes an issue with affix settings, when used in combination
with group settings, which could result in no found settings when used
to get a setting for a namespace.
Lastly logging has been slightly changed, so that filtered settings now
only log the setting key.
Another bug has been fixed for the mock log appender, which did not
work, when checking for the exact message.

This commit is related to #27260. Currently have a channel context that
implements reading and writing logic for socket channels. Additionally,
we have exception contexts to handle exceptions. And accepting contexts
to handle accepted channels. This PR introduces a ChannelContext that
handles close and exception handling for all channel types.
Additionally, it has implementers that provide specific functionality
for socket channels (read and writing). And specific functionality for
server channels (accepting).
There a number of tests in `AbstractSimpleTransportTestCase` that
create `MockTcpTransport` impls. This commit modifies two of these tests
to use the transport implementation that is being tested.
This commit is related to #27260. Right now we have separate read and
write contexts for implementing specific protocol logic. However, some
protocols require a closer relationship between read and write
operations than is allowed by our current model. An example is HTTP
which might require a write if some problem with request parsing was
encountered.
Additionally, some protocols require close messages to be sent when a
channel is shutdown. This is also problematic in our current model,
where we assume that channels should simply be queued for close and
forgotten.
This commit transitions to a single ChannelContext which implements
all read, write, and close logic for protocols. It is the job of the
context to tell the selector when to close the channel. A channel can
still be manually queued for close with a selector. This is how server
channels are closed for now. And this route allows timeout mechanisms on
normal channel closes to be implemented.
This logging message adds considerable noise to many REST tests, if you
are using something like HTTP basic auth in every API call or set any custom
header.
The log level moves from info to debug, so can still be seen if wanted.

The composite aggregation defers the collection of sub-aggregations to a second pass that visits documents only if they
appear in the top buckets. Though the scorer for sub-aggregations is not set on this second pass and generates an NPE if any sub-aggregation
tries to access the score. This change creates a scorer for the second pass and makes sure that sub-aggs can use it safely to check the score of
the collected documents.
The method `initiateChannel` on `TcpTransport` is explicit in that
channels can be connect asynchronously. All production implementations
do connect asynchronously. Only the blocking `MockTcpTransport`
connects in a synchronous manner. This avoids testing some of the
blocking code in `TcpTransport` that waits on connections to complete.
Additionally, it requires a more extensive method signature than
required for other transports.
This commit modifies the `MockTcpTransport` to make these connections
asynchronously on a different thread. Additionally, it simplifies that
`initiateChannel` method signature.
This is related to #27933. It introduces a jar named elasticsearch-core
in the lib directory. This commit moves the JarHell class from server to

Today a primary shard transfers the most recent commit point to a
replica shard in a file-based recovery. However, the most recent commit
may not be a "safe" commit; this causes a replica shard not having a
safe commit point until it can retain a safe commit by itself.
This commits collapses the snapshot deletion policy into the combined
deletion policy and modifies the peer recovery source to send a safe
commit.

This commit adds the ability to package multiple plugins in a single zip.
The zip file for a meta plugin must contains the following structure:
|____elasticsearch/
| |____ <plugin1> <-- The plugin files for plugin1 (the content of the elastisearch directory)
| |____ <plugin2> <-- The plugin files for plugin2
| |____ meta-plugin-descriptor.properties <-- example contents below
The meta plugin properties descriptor is mandatory and must contain the following properties:
description: simple summary of the meta plugin.
name: the meta plugin name
The installation process installs each plugin in a sub-folder inside the meta plugin directory.
The example above would create the following structure in the plugins directory:
|_____ plugins
| |____ <name_of_the_meta_plugin>
| | |____ meta-plugin-descriptor.properties
| | |____ <plugin1>
| | |____ <plugin2>
If the sub plugins contain a config or a bin directory, they are copied in a sub folder inside the meta plugin config/bin directory.
|_____ config
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
|_____ bin
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
The sub-plugins are loaded at startup like normal plugins with the same restrictions; they have a separate class loader and a sub-plugin
cannot have the same name than another plugin (or a sub-plugin inside another meta plugin).
It is also not possible to remove a sub-plugin inside a meta plugin, only full removal of the meta plugin is allowed.

This commit adds the infrastructure to plugin building and loading to
allow one plugin to extend another. That is, one plugin may extend
another by the "parent" plugin allowing itself to be extended through
java SPI. When all plugins extending a plugin are finished loading, the
"parent" plugin has a callback (through the ExtensiblePlugin interface)
allowing it to reload SPI.
This commit also adds an example plugin which uses as-yet implemented
extensibility (adding to the painless whitelist).
This commit disables the nio transport as an option for the test
transport in integration tests. This is because it does not currently
run properly in intellij due to socket permissions. It should be
reenabled once #27881 is merged (and the proper permissions are added).

Today when we get a metadata snapshot directly from a store directory,

create a CheckIndex under the metadata lock.

Closes#27821
We currently have a complicated port assignment scheme to make sure that the nodes span off by the internal test cluster will be assigned fixed port ranges that will also not collide between clusters. The port ranges need to be fixed in advance so that the nodes will be able to find each other via `UnicastZenPing`.
This approach worked well for the last few years but we are now at a point that our testing has grown beyond it and we exceed the 5 reusable ranges per JVM. This means that nodes are not always assigned the first 5 ports in their range which causes cluster formation issues. On top of that, most of the clusters that are span up don't even rely on `UnicastZenPing` but rather `MockZenPings` that uses in memory maps for discovery (with the down side that they are not influenced by network disruption simulations).
This PR changes `InternalTestCluster` to use port 0 as a fixed assignment. This will allow the OS to manage ports and will ensure we don't have collisions. For tests that need to simulate network disruptions (and thus can't use `MockZenPings`), a new `UnicastHostProvider` is introduced that is based on the current state of the test cluster. Since that is only resolved at run time, it is aware of the port assignments of the OS.

This commit moves GlobalCheckpointTracker from the engine to IndexShard, where it better fits logically: Tracking the global checkpoint based on the local checkpoints of all shards in the replication group is not a property of the engine, but rather a property fulfilled by the current primary shard. The LocalCheckpointTracker on the other hand is driven by the contents of the local translog. By moving GlobalCheckpointTracker to IndexShard, it makes little sense to keep the SequenceNumbersService class around - it would only wrap the LocalCheckpointTracker. This commit therefore removes the class and replaces occurrences of SequenceNumbersService in the engine directly by LocalCheckpointTracker.

When snapshotting the primary we capture a lucene commit at an arbitrary moment from a sequence number perspective. This means that it is possible that the commit misses operations and that there is a gap between the local checkpoint in the commit and the maximum sequence number.
When we restore, this will create a primary that "misses" operations and currently will mean that the sequence number system is stuck (i.e., the local checkpoint will be stuck). To fix this we should fill in gaps when we restore, in a similar fashion to normal store recovery.
Currently randomNonNegativeLong() returns 0 half as often as any positive long,
but random number generators are typically expected to return
uniformly-distributed values unless otherwise specified. This fixes this issue
by mapping Long.MIN_VALUE directly onto 0 rather than resampling.
This commit is related to #27260. It adds a base NioGroup for use in
different transports. This class creates and starts the underlying
selectors. Different protocols or transports are established by passing
the ChannelFactory to the bindServerChannel or openChannel
methods. This allows a TcpChannelFactory to be passed which will
create and register channels that support the elasticsearch tcp binary
protocol or a channel factory that will create http channels (or other).
When an ESSelector is created an underlying nio selector is opened. This
selector is closed by the event loop after close has been signalled by
another thread.
However, there is a possibility that an ESSelector is created and some
exception in the startup process prevents it from ever being started
(however, close will still be called). The allows the selector to leak.
This commit addresses this issue by having the signalling thread close
the selector if the event loop is not running when close is signalled.
Allowing `_doc` as a type will enable users to make the transition to 7.0
smoother since the index APIs will be `PUT index/_doc/id` and `POST index/_doc`.
This also moves most of the documentation to `_doc` as a type name.
Closes#27750Closes#27751
We need to keep index commits and translog operations up to the current

index deletion policy.
Relates #10708
This commit attempts to continue unifying the logic between different
transport implementations. As transports call a `TcpTransport` callback
when a new channel is accepted, there is no need to internally track
channels accepted. Instead there is a set of accepted channels in
`TcpTransport`. This set is used for metrics and shutting down channels.
This is related to #27563. This commit modifies the
InboundChannelBuffer to support releasable byte pages. These byte
pages are provided by the PageCacheRecycler. The PageCacheRecycler
must be passed to the Transport with this change.
This is a follow up to #27695. This commit adds a test checking that
across multiple writes using multiple buffers, a write operation
properly keeps track of which buffers still need to be written.
This is a followup to #27551. That commit introduced a bug where the
incorrect byte buffers would be returned when we attempted a write. This
commit fixes the logic.
This is related to #27563. In order to interface with java nio, we must
have buffers that are compatible with ByteBuffer. This commit introduces
a basic ByteBufferReference to easily allow transferring bytes off the
wire to usage in the application.
Additionally it introduces an InboundChannelBuffer. This is a buffer
that can internally expand as more space is needed. It is designed to
be integrated with a page recycler so that it can internally reuse pages.
The final piece is moving all of the index work for writing bytes to a
channel into the WriteOperation.
This commit adds a new dynamic cluster setting named `search.max_buckets` that can be used to limit the number of buckets created per shard or by the reduce phase. Each multi bucket aggregator can consume buckets during the final build of the aggregation at the shard level or during the reduce phase (final or not) in the coordinating node. When an aggregator consumes a bucket, a global count for the request is incremented and if this number is greater than the limit an exception is thrown (TooManyBuckets exception).
This change adds the ability for multi bucket aggregator to "consume" buckets in the global limit, the default is 10,000. It's an opt-in consumer so each multi-bucket aggregator must explicitly call the consumer when a bucket is added in the response.

* Add accounting circuit breaker and track segment memory usage
This commit adds a new circuit breaker "accounting" that is used for tracking
the memory usage of non-request-tied memory users. It also adds tracking for the
amount of Lucene segment memory used by a shard as a user of the new circuit
breaker.
The Lucene segment memory is updated when the shard refreshes, and removed when
the shard relocates away from a node or is deleted. It should also be noted that
all tracking for segment memory uses `addWithoutBreaking` so as not to fail the
shard if a limit is reached.
The `accounting` breaker has a default limit of 100% and will contribute to the
parent breaker limit.

This potential issue was exposed when I saw this PR #27542. Essentially
we currently execute the write listeners all over the place without

If the listener throws an execption, the exception is caught and logged
at the `warn` level.

Decouple nio constructs from the tcp transport (#27484)
...
Pull request #20220 added a change where the store files
that have the same name but are different from the ones in the
snapshot are deleted first before the snapshot is restored.
This logic was based on the `Store.RecoveryDiff.different`
set of files which works by computing a diff between an
existing store and a snapshot.
This works well when the files on the filesystem form valid
shard store, ie there's a `segments` file and store files
are not corrupted. Otherwise, the existing store's snapshot
metadata cannot be read (using Store#snapshotStoreMetadata())
and an exception is thrown
(CorruptIndexException, IndexFormatTooOldException etc) which
is later caught as the begining of the restore process
(see RestoreContext#restore()) and is translated into
an empty store metadata (Store.MetadataSnapshot.EMPTY).
This will make the deletion of different files introduced
in #20220 useless as the set of files will always be empty
even when store files exist on the filesystem. And if some
files are present within the store directory, then restoring
a snapshot with files with same names will fail with a
FileAlreadyExistException.
This is part of the #26865 issue.
There are various cases were some files could exist in the
store directory before a snapshot is restored. One that
Igor identified is a restore attempt that failed on a node
and only first files were restored, then the shard is allocated
again to the same node and the restore starts again (but fails
because of existing files). Another one is when some files
of a closed index are corrupted / deleted and the index is
restored.
This commit adds a test that uses the infrastructure provided
by IndexShardTestCase in order to test that restoring a shard
succeed even when files with same names exist on filesystem.
Related to #26865
This is related to #27260. Currently, basic nio constructs (nio
channels, the channel factories, selector event handlers, etc) implement
logic that is specific to the tcp transport. For example, NioChannel
implements the TcpChannel interface. These nio constructs at some point
will also need to support other protocols (ex: http).
This commit separates the TcpTransport logic from the nio building
blocks.
This change removes the module named aggs-composite and adds the `composite` aggs
as a core aggregation. This allows other plugins to use this new aggregation
and simplifies the integration in the HL rest client.
This is related to #27260. Currently every nio channel has a profile
field. Profile is a concept that only relates to the tcp transport. Http
channels will not have profiles. This commit moves the profile from the
nio channel to the read context. The context is the level that protocol
specific features and logic should live.

...
Currently we use ActionListener<TcpChannel> for connect, close, and send
message listeners in TcpTransport. However, all of the listeners have to
capture a reference to a channel in the case of the exception api being
called. This commit changes these listeners to be type <Void> as passing
the channel to onResponse is not necessary. Additionally, this change
makes it easier to integrate with low level transports (which use
different implementations of TcpChannel).
This commit removes the ability to use ${prompt.secret} and
${prompt.text} as valid config settings. Secure settings has obsoleted
the need for this, and it cleans up some of the code in Bootstrap.
This is related to #27260. Currently, every ESSelector keeps track of
all channels that are registered with it. ESSelector is just an
abstraction over a raw java nio selector. The java nio selector already
tracks its own selection keys. This commit removes our tracking and
relies on the java nio selector tracking.
It leads to harder-to-parse logs that look like this:
```

This is related to #27260. In the nio transport work we do not catch or
handle `Throwable`. There are a few places where we have exception
handlers that accept `Throwable`. This commit removes those cases.
This commit is a follow up to the work completed in #27132. Essentially
it transitions two more methods (sendMessage and getLocalAddress) from
Transport to TcpChannel. With this change, there is no longer a need for
TcpTransport to be aware of the specific type of channel a transport
returns. So that class is no longer parameterized by channel type.
This is a follow up to #27132. As that PR greatly simplified the
connection logic inside a low level transport implementation, much of
the functionality provided by the NioClient class is no longer
necessary. This commit removes that class.

* This change adds a module called `aggs-composite` that defines a new aggregation named `composite`.
The `composite` aggregation is a multi-buckets aggregation that creates composite buckets made of multiple sources.
The sources for each bucket can be defined as:
* A `terms` source, values are extracted from a field or a script.
* A `date_histogram` source, values are extracted from a date field and rounded to the provided interval.
This aggregation can be used to retrieve all buckets of a deeply nested aggregation by flattening the nested aggregation in composite buckets.
A composite buckets is composed of one value per source and is built for each document as the combinations of values in the provided sources.
For instance the following aggregation:
````
"test_agg": {
"terms": {
"field": "field1"
},
"aggs": {
"nested_test_agg":
"terms": {
"field": "field2"
}
}
}
````
... which retrieves the top N terms for `field1` and for each top term in `field1` the top N terms for `field2`, can be replaced by a `composite` aggregation in order to retrieve **all** the combinations of `field1`, `field2` in the matching documents:
````
"composite_agg": {
"composite": {
"sources": [
{
"field1": {
"terms": {
"field": "field1"
}
}
},
{
"field2": {
"terms": {
"field": "field2"
}
}
},
}
}
````
The response of the aggregation looks like this:
````
"aggregations": {
"composite_agg": {
"buckets": [
{
"key": {
"field1": "alabama",
"field2": "almanach"
},
"doc_count": 100
},
{
"key": {
"field1": "alabama",
"field2": "calendar"
},
"doc_count": 1
},
{
"key": {
"field1": "arizona",
"field2": "calendar"
},
"doc_count": 1
}
]
}
}
````
By default this aggregation returns 10 buckets sorted in ascending order of the composite key.
Pagination can be achieved by providing `after` values, the values of the composite key to aggregate after.
For instance the following aggregation will aggregate all composite keys that sorts after `arizona, calendar`:
````
"composite_agg": {
"composite": {
"after": {"field1": "alabama", "field2": "calendar"},
"size": 100,
"sources": [
{
"field1": {
"terms": {
"field": "field1"
}
}
},
{
"field2": {
"terms": {
"field": "field2"
}
}
}
}
}
````
This aggregation is optimized for indices that set an index sorting that match the composite source definition.
For instance the aggregation above could run faster on indices that defines an index sorting like this:
````
"settings": {
"index.sort.field": ["field1", "field2"]
}
````
In this case the `composite` aggregation can early terminate on each segment.
This aggregation also accepts multi-valued field but disables early termination for these fields even if index sorting matches the sources definition.
This is mandatory because index sorting picks only one value per document to perform the sort.
Right now our different transport implementations must duplicate
functionality in order to stay compliant with the requirements of
TcpTransport. They must all implement common logic to open channels,
close channels, keep track of channels for eventual shutdown, etc.
Additionally, there is a weird and complicated relationship between
Transport and TransportService. We eventually want to start merging
some of the functionality between these classes.
This commit starts moving towards a world where TransportService retains
all the application logic and channel state. Transport implementations
in this world will only be tasked with returning a channel when one is
requested, calling transport service when a channel is accepted from
a server, and starting / stopping itself.
Specifically this commit changes how channels are opened and closed. All
Transport implementations now return a channel type that must comply with
the new TcpChannel interface. This interface has the methods necessary
for TcpTransport to completely manage the lifecycle of a channel. This
includes setting the channel up, waiting for connection, adding close
listeners, and eventually closing.

We use affix settings to group settings / values under a certain namespace.
In some cases like login information for instance a setting is only valid if
one or more other settings are present. For instance `x.test.user` is only valid
if there is an `x.test.passwd` present and vice versa. This change allows to specify
such a dependency to prevent settings updates that leave settings in an inconsistent
state.

We cut over to internal and external IndexReader/IndexSearcher in #26972 which uses
two independent searcher managers. This has the downside that refreshes of the external
reader will never clear the internal version map which in-turn will trigger additional
and potentially unnecessary segment flushes since memory must be freed. Under heavy
indexing load with low refresh intervals this can cause excessive segment creation which
causes high GC activity and significantly increases the required segment merges.
This change adds a dedicated external reference manager that delegates refreshes to the
internal reference manager that then `steals` the refreshed reader from the internal
reference manager for external usage. This ensures that external and internal readers
are consistent on an external refresh. As a sideeffect this also releases old segments
referenced by the internal reference manager which can potentially hold on to already merged
away segments until it is refreshed due to a flush or indexing activity.

If an out of memory error is thrown while merging, today we quietly
rewrap it into a merge exception and the out of memory error is
lost. Instead, we need to rethrow out of memory errors, and in fact any
fatal error here, and let those go uncaught so that the node is torn
down. This commit causes this to be the case.
Relates #27265
The warnings headers have a fairly limited set of valid characters
(cf. quoted-text in RFC 7230). While we have assertions that we adhere
to this set of valid characters ensuring that our warning messages do
not violate the specificaion, we were neglecting the possibility that
arbitrary user input would trickle into these warning headers. Thus,
missing here was tests for these situations and encoding of characters
that appear outside the set of valid characters. This commit addresses
this by encoding any characters in a deprecation message that are not
from the set of valid characters.
Relates #27269
This change adds a new `_split` API that allows to split indices into a new
index with a power of two more shards that the source index. This API works
alongside the `_shrink` API but doesn't require any shard relocation before
indices can be split.
The split operation is conceptually an inverse `_shrink` operation since we
initialize the index with a _syntetic_ number of routing shards that are used
for the consistent hashing at index time. Compared to indices created with
earlier versions this might produce slightly different shard distributions but
has no impact on the per-index backwards compatibility. For now, the user is
required to prepare an index to be splittable by setting the
`index.number_of_routing_shards` at index creation time. The setting allows the
user to prepare the index to be splittable in factors of
`index.number_of_routing_shards` ie. if the index is created with
`index.number_of_routing_shards: 16` and `index.number_of_shards: 2` it can be
split into `4, 8, 16` shards. This is an intermediate step until we can make
this the default. This also allows us to safely backport this change to 6.x.
The `_split` operation is implemented internally as a DeleteByQuery on the
lucene level that is executed while the primary shards execute their initial
recovery. Subsequent merges that are triggered due to this operation will not be
executed immediately. All merges will be deferred unti the shards are started
and will then be throttled accordingly.
This change is intended for the 6.1 feature release but will not support pre-6.1
indices to be split unless these indices have been shrunk before. In that case
these indices can be split backwards into their original number of shards.
While it's not possible to upgrade the Jackson dependencies
to their latest versions yet (see #27032 (comment) for more)
it's still possible to upgrade to the latest 2.8.x version.
We have an hidden setting called `index.queries.cache.term_queries` that disables caching of term queries in the query cache.
Though term queries are not cached in the Lucene UsageTrackingQueryCachingPolicy since version 6.5.
This makes the es policy useless but also makes it impossible to re-enable caching for term queries.
This change appeared in Lucene 6.5 so this setting is no-op since version 5.4 of Elasticsearch
The change in this PR removes the setting and the custom policy.
Only tests should use the single argument Environment constructor. To
enforce this the single arg Environment constructor has been replaced with
a test framework factory method.
Production code (beyond initial Bootstrap) should always use the same
Environment object that Node.getEnvironment() returns. This Environment
is also available via dependency injection.

When partitioning version constants into released and unreleased
versions, today we have a bug in finding the last unreleased
version. Namely, consider the following version constants on the 6.x
branch: ..., 5.6.3, 5.6.4, 6.0.0-alpha1, ..., 6.0.0-rc1, 6.0.0-rc2,
6.0.0, 6.1.0. In this case, our convention dictates that: 5.6.4, 6.0.0,
and 6.1.0 are unreleased. Today we correctly detect that 6.0.0 and 6.1.0
are unreleased, and then we say the previous patch version is unreleased
too. The problem is the logic to remove that previous patch version is
broken, it does not skip alphas/betas/RCs which have been released. This
commit fixes this by skipping backwards over pre-release versions when
finding the previous patch version to remove.

* Enhances exists queries to reduce need for `_field_names`
Before this change we wrote the name all the fields in a document to a `_field_names` field and then implemented exists queries as a term query on this field. The problem with this approach is that it bloats the index and also affects indexing performance.
This change adds a new method `existsQuery()` to `MappedFieldType` which is implemented by each sub-class. For most field types if doc values are available a `DocValuesFieldExistsQuery` is used, falling back to using `_field_names` if doc values are disabled. Note that only fields where no doc values are available are written to `_field_names`.
Closes#26770

* implements existsQuery explicitly on every mapper
* Reinstates ability to perform term query on `_field_names`

These values will need to be changed after backporting this PR to 6.x
It is required in order to work correctly with bulk scorer implementations
that change the scorer during the collection process. Otherwise sub collectors
might call `Scorer.score()` on the wrong scorer.

While opening a connection to a node, a channel can subsequently
close. If this happens, a future callback whose purpose is to close all
other channels and disconnect from the node will fire. However, this
future will not be ready to close all the channels because the
connection will not be exposed to the future callback yet. Since this
callback is run once, we will never try to disconnect from this node
again and we will be left with a closed channel. This commit adds a
check that all channels are open before exposing the channel and throws
a general connection exception. In this case, the usual connection retry
logic will take over.
Relates #26932
Today we return a `String[]` that requires copying values for every
access. Yet, we already store the setting as a list so we can also directly
return the unmodifiable list directly. This makes list / array access in settings
a much cheaper operation especially if lists are large.
The shard preference _primary, _replica and its variants were useful
for the asynchronous replication. However, with the current impl, they
are no longer useful and should be removed.
Closes#26335
* Add additional low-level logging handler
We have the trace handler which is useful for recording sent messages
but there are times where it would be useful to have more low-level
logging about the events occurring on a channel. This commit adds a
logging handler that can be enabled by setting a certain log level
(org.elasticsearch.transport.netty4.ESLoggingHandler) to trace that
provides trace logging on low-level channel events and includes some
information about the request/response read/write events on the channel
as well.
* Remove imports
* License header
* Remove redundant
* Add test
* More assertions
Today we represent each value of a list setting with it's own dedicated key
that ends with the index of the value in the list. Aside of the obvious
weirdness this has several issues especially if lists are massive since it
causes massive runtime penalties when validating settings. Like a list of 100k
words will literally cause a create index call to timeout and in-turn massive
slowdown on all subsequent validations runs.
With this change we use a simple string list to represent the list. This change
also forbids to add a settings that ends with a .0 which was internally used to
detect a list setting. Once this has been rolled out for an entire major
version all the internal .0 handling can be removed since all settings will be
converted.
Relates to #26723
Since `#getAsMap` exposes internal representation we are trying to remove it
step by step. This commit is cleaning up some xcontent writing as well as
usage in tests
This commit fixes a #26855. Right now we set SO_LINGER to 0 if we are
stopping the transport. This can throw a ChannelClosedException if the
raw channel is already closed. We have a number of scenarios where it is
possible this could be called with a channel that is already closed.
This commit fixes the issue be checking that the channel is not closed
before attempting to set the socket option.
Currently we only log generic messages about errors in logs from the
nio event handler. This means that we do not know which channel had
issues connection, reading, writing, etc.
This commit changes the logs to include the local and remote addresses
and profile for a channel.
We use group settings historically instead of using a prefix setting which is more restrictive and type safe. The majority of the usecases needs to access a key, value map based on the _leave node_ of the setting ie. the setting `index.tag.*` might be used to tag an index with `index.tag.test=42` and `index.tag.staging=12` which then would be turned into a `{"test": 42, "staging": 12}` map. The group settings would always use `Settings#getAsMap` which is loosing type information and uses internal representation of the settings. Using prefix settings allows now to access such a method type-safe and natively.
