Doc-value fields now return a value that is based on the mappings rather than
the script implementation by default.
This deprecates the special `use_field_mapping` docvalue format which was added
in #29639 only to ease the transition to 7.x and it is not necessary anymore in
7.0.
This commit restores a noop version of the AllFieldMapper that is instanciated only
for indices created in 6x. We need this metadata field mapper to be present in this version
in order to allow the upgrade of indices that explicitly disable _all (enabled: false).
The mapping of these indices contains a reference to the _all field that we cannot remove
in 7 so we'll need to keep this metadata mapper in 7x. Since indices created in 6x will not
be compatible with 8, we'll remove this noop mapper in the next major version.
Closes#37429
The certgen, certutil and saml-metadata tools did not correctly return
their exit code to the calling shell.
These commands now explicitly exit with the code that was returned
from the main(args, terminal) method.
Added deprecation warnings for use of include_type_name in put/get index templates.
HLRC changes:
GetIndexTemplateRequest has a new client-side class which is a copy of server's GetIndexTemplateResponse but modified to be typeless.
PutIndexTemplateRequest has a new client-side counterpart which doesn't use types in the mappings

This commit adds classifiers to the distributions indicating the
OS (for archives) and platform. The current OSes are for windows, darwin (ie
macos) and linux. This change will allow future OS/architecture specific
changes to the distributions. Note the docs using distribution links
have been updated, but will be reworked in a followup to make OS
specific instructions for the archives.
In order to support JSON log format, a custom pattern layout was used and its configuration is enclosed in ESJsonLayout. Users are free to use their own patterns, but if smooth Beats integration is needed, they should use ESJsonLayout. EvilLoggerTests are left intact to make sure user's custom log patterns work fine.
To populate additional fields node.id and cluster.uuid which are not available at start time,
a cluster state update will have to be received and the values passed to log4j pattern converter.
A ClusterStateObserver.Listener is used to receive only one ClusteStateUpdate. Once update is received the nodeId and clusterUUid are set in a static field in a NodeAndClusterIdConverter.
Following fields are expected in JSON log lines: type, tiemstamp, level, component, cluster.name, node.name, node.id, cluster.uuid, message, stacktrace
see ESJsonLayout.java for more details and field descriptions
Docker log4j2 configuration is now almost the same as the one use for ES binary.
The only difference is that docker is using console appenders, whereas ES is using file appenders.

The packaging tests currently have a test which installs elasticsearch,
removes it, modifies ownership of /etc/elasticsearch, and
reinstalls. It then checks that the /etc/elasticsearch directory has
ownership that the package expects. But the recursive change touches
files not owned by the package. In the past this worked because we did a
recursive ownership change within the package postinst. However, that
was recently removed, and thus this test no longer makes sense.
The ingest date processor is currently only able to parse joda formats.
However it is not using the existing elasticsearch classes but access
joda directly. This means that our existing BWC layer does not notify
the user about deprecated formats. This commit switches to use the
exising Elasticsearch Joda methods to acquire a date format, that
includes the BWC check and the ability to parse java 8 dates.
The date parsing in ingest has also another extra feature, that the
fallback year, when a date format without a year is used, is the current
year, and not 1970 like usual. This is currently not properly supported
in the DateFormatter class. As this is the only case for this feature
and java time can take care of this using the toZonedDateTime() method,
a workaround just for the joda time parser has been created, that can be
removed soon again from 7.0.
elasticsearch-node tool helps to restore cluster if half or more of
master eligible nodes are lost. Of course, all bets are off, regarding
data consistency.
There are two parts of the tool: unsafe-bootstrap to be used when there
is still at least one master-eligible node alive and detach-cluster,
when there are no master-eligible nodes left.
This commit implements the first part.
Docs for the tool will be added separately as a part of #37812.
* Testing conventions now checks for tests in main

This commit moves the aggregation and mapping code from joda time to
java time. This includes field mappers, root object mappers, aggregations with date
histograms, query builders and a lot of changes within tests.
The cut-over to java time is a requirement so that we can support nanoseconds
properly in a future field mapper.

Users may require the sequence number and primary terms to perform optimistic concurrency control operations. Currently, you can get the sequence number via the `docvalues_fields` API but the primary term is not accessible because it is maintained by the `SeqNoFieldMapper` and the infrastructure can't find it.
This commit adds a dedicated sub fetch phase to return both numbers that is connected to a new `seq_no_primary_term` parameter.
The integ tests currently use the raw zip project name as the
distribution type. This commit simplifies this specification to be
"default" or "oss". Whether zip or tar is used should be an internal
implementation detail of the integ test setup, which can (in the future)
be platform specific.
This is a continuation of #28667 and has as goal to convert all executors to propagate errors to the
uncaught exception handler. Notable missing ones were the direct executor and the scheduler. This
commit also makes it the property of the executor, not the runnable, to ensure this property. A big
part of this commit also consists of vastly improving the test coverage in this area.
Some systems default to a nofile ulimit of 65535. To reduce the pain of
deploying Elasticsearch to such systems, this commit lowers the required
limit from 65536 to 65535.
This commit removes permission editing commands from the postinst
scriptlet. Instead, we now fully configure the owner/group (as well as
sticky bit) for these files and directories.

* Default include_type_name to false for get and put mappings.
* Default include_type_name to false for get field mappings.
* Add a constant for the default include_type_name value.
* Default include_type_name to false for get and put index templates.
* Default include_type_name to false for create index.
* Update create index calls in REST documentation to use include_type_name=true.

* Clarify the different IndexTemplateMetaData toXContent methods.
* Fix FullClusterRestartIT#testSnapshotRestore.
* Fix the ml_anomalies_default_mappings test.
* Fix GetFieldMappingsResponseTests and GetIndexTemplateResponseTests.
We make sure to specify include_type_name=true during xContent parsing,
so we continue to test the legacy typed responses. XContent generation
for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.
This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.
* Fix more REST tests.
* Improve some wording in the create index documentation.
* Add a note about types removal in the create index docs.
* Fix SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL.
* Make sure to mention include_type_name in the REST docs for affected APIs.
* Make sure to use 'expression == false' in FullClusterRestartIT.
* Mention include_type_name in the REST templates docs.

When the deprecation log is written to within scripting support code
like ScriptDocValues, it runs under the reduces privileges of scripts.
Sometimes this can trigger log rolling, which then causes uncaught
security errors, as was handled in #28485. While doing individual
deprecation handling within each deprecation scripting location is
possible, there are a growing number of deprecations in scripts.
This commit wraps the logging call within the deprecation logger use a
doPrivileged block, just was we would within individual logging call
sites for scripting utilities.
In Lucene 8 searches can skip non-competitive hits if the total hit count is not requested.
It is also possible to track the number of hits up to a certain threshold. This is a trade off to speed up searches while still being able to know a lower bound of the total hit count. This change adds the ability to set this threshold directly in the track_total_hits search option. A boolean value (true, false) indicates whether the total hit count should be tracked in the response. When set as an integer this option allows to compute a lower bound of the total hits while preserving the ability to skip non-competitive hits when enough matches have been collected.

* Deprecate types in index API
- deprecate type-based constructors of IndexRequest
- update tests to use typeless IndexRequest constructors
- no yaml tests as they have been already added in #35790

The following updates were made:
* Add deprecation warnings to `RestUpdateAction`, plus a test in `RestUpdateActionTests`.
* Deprecate relevant methods on the Java HLRC requests/ responses.
* Add HLRC integration tests for the typed APIs.
* Update documentation (for both the REST API and Java HLRC).
* Fix failing integration tests.
Because of an earlier PR, the REST yml tests were already updated (one version without types, and another legacy version that retains types).
There are certain BootstrapCheck checks that may need access environment-specific
values. Watcher's EncryptSensitiveDataBootstrapCheck passes in the node's environment
via a constructor to bypass the shortcoming in BootstrapContext. This commit
pulls in the node's environment into BootstrapContext.
Another case is found in #36519, where it is useful to check the state of the
data-path. Since PathUtils.get and Paths.get are forbidden APIs, we rely on
the environment to retrieve references to things like node data paths.
This means that the BootstrapContext will have the same Settings used in the
Environment, which currently differs from the Node's settings.
data files under the cluster name subdirectory has been deprecated and was

Redeprecates the `/_xpack/rollup` endpoints in favor of `/_rollup`.
When we cleanup the rollup in a cluster containing 6.x nodes we need to
use `/_xpack/rollup` instead of `/_rollup` because the 6.x nodes don't
know about `/_rollup`. In those cases we must ignore the deprecation
warnings that the 7.0 node will return for the end point.

Moves all remaining (rolling-upgrade and mixed-version) REST tests to use Zen2. To avoid adding
extra configuration, it relies on Zen2 being set as the default discovery type. This required a few
smaller changes in other tests. I've removed AzureMinimumMasterNodesTests which tests Zen1
functionality and dates from a time where host providers were not configurable and each cloud
plugin had its own discovery.type, subclassing the ZenDiscovery class. I've also adapted a few tests
which were unnecessarily adding addTestZenDiscovery = false for the same legacy reasons. Finally,
this also moves the unconfigured-node-name REST test to Zen2, testing the auto-bootstrapping
functionality in development mode when no discovery configuration is provided.
In real deployments it is important that clusters are properly configured to
avoid accidentally forming multiple independent clusters at cluster
bootstrapping time. However we also expect to be able to unpack Elasticsearch
and start up one or more nodes without any up-front configuration, and have
them do their best to find each other and form a cluster after a few seconds.
This change adds a delayed automatic bootstrapping process to nodes that start
up with no relevant settings set to support the desired out-of-the-box
experience without compromising safety in properly-configured deployments.
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

`MockTcpTransport` with `MockNioTransport`.
If `dpkg` fails, try and look for who has `/var/lib/dpkg/lock` open. If

The `wait_for_metadata_version` parameter will instruct the cluster state
api to only return a cluster state until the metadata's version is equal or
greater than the version specified in `wait_for_metadata_version`. If
the specified `wait_for_timeout` has expired then a timed out response
is returned. (a response with no cluster state and wait for timed out flag set to true)
In the case metadata's version is equal or higher than `wait_for_metadata_version`
then the api will immediately return.
This feature is useful to avoid external components from constantly
polling the cluster state to whether somethings have changed in the
cluster state's metadata.

Some very old ancient versions of Linux do not have /etc/os-release. For
example, old Red Hat-like OS. This commit adds a fallback for handling
pretty name for these OS.
Some OS (e.g., Oracle Linux Server 6.9) have a trailing space at the end
of the PRETTY_NAME line in /etc/os-release. This commit addresses this
by accounting for this trailing space when extracting the pretty name.

Today our OS information returned in node stats only returns a
high-level name of the OS (e.g., "Linux"). Yet, for some uses this is
too high-level and knowing at a finer level of granularity the
underlying OS can be useful. This commit extracts the pretty name on
Linux from /etc/os-release. This pretty name usually includes the Linux
vendor and the Linux vendor version number (e.g., Fedora 28).
With this change, `Version` no longer carries information about the qualifier,
we still need a way to show the "display version" that does have both
qualifier and snapshot. This is now stored by the build and red from `META-INF`.
Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.
I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler
These files don't *need* `settings` either, but this change is large
enough as is.

The java yaml test runner supports sending request headers, yet not all clients support headers. This commit makes sure that we enforce adding a skip section with feature "headers" whenever headers are used in a do section as part of a test. That decreases the chance for new tests to break client builds due to the missing skip section.
Closes#34650
Drops the `Settings` member from `AbstractComponent`, moving it from the
base class on to the classes that use it. For the most part this is a
mechanical change that doesn't drop `Settings` accesses. The one
exception to this is naming threads where it switches from an invocation
that passes `Settings` and extracts the node name to one that explicitly
passes the node name.
This change doesn't drop the `Settings` argument from
`AbstractComponent`'s ctor because this change is big enough as is.
We'll do that in a follow up change.
Drops the `deprecationLogger` from `AbstractComponent`, moving it to
places where we need it. This saves us from building a bunch of
`DeprecationLogger`s that we don't need.

The pull request #34338 added strict deprecation mode to the REST tests
and adds the copy_settings param when testing the shrink of an index.
This parameter has been added in 6.4.0 and will be removed in 8.0, so
the test now needs to take care of the old cluster version when adding
the copy_settings param.
After discussing on the team's FixItFriday, we concluded that
static final instance variables that are mutable should be lowercased.
Historically, DeprecationLogger was uppercased more frequently than lowercased.
#33708 introduced a strict deprecation mode that makes a REST request
fail if there is a warning header in the response returned by
Elasticsearch (usually a deprecation message signaling that a feature
or a field has been deprecated).
This change adds the strict deprecation mode into the REST integration
tests, and makes the tests fail if a deprecated feature is used. Also
any test using a deprecated feature has been modified to pass the build.
The YAML integration tests already analyzed HTTP warnings so they do
not use this mode, keeping their "expected vs actual" behavior.
Today we index the same number of documents (50 documents) in each round
of the rolling upgrade tests. If the actual count does not match, we can
not guess the problematic round.

Changes the default of the `node.name` setting to the hostname of the
machine on which Elasticsearch is running. Previously it was the first 8
characters of the node id. This had the advantage of producing a unique
name even when the node name isn't configured but the disadvantage of
being unrecognizable and not being available until fairly late in the
startup process. Of particular interest is that it isn't available until
after logging is configured. This forces us to use a volatile read
whenever we add the node name to the log.
Using the hostname is available immediately on startup and is generally
recognizable but has the disadvantage of not being unique when run on
machines that don't set their hostname or when multiple elasticsearch
processes are run on the same host. I believe that, taken together, it
is better to default to the hostname.
1. Running multiple copies of Elasticsearch on the same node is a fairly
advanced feature. We do it all the as part of the elasticsearch build
for testing but we make sure to set the node name then.
2. That the node.name defaults to some flavor of "localhost" on an
unconfigured box feels like it isn't going to come up too much in
production. I expect most production deployments to at least set the
hostname.
As a bonus, production deployments need no longer set the node name in
most cases. At least in my experience most folks set it to the hostname
anyway.
In #33241 we moved the file-based discovery functionality to core
Elasticsearch, but preserved the `discovery-file` plugin, and support for the
existing location of the `unicast_hosts.txt` file, for BWC reasons. This commit
completes the removal of this plugin.
New plugin for annotated_text field type.
Largely a copy of `text` field type but adds ability to include markdown-like syntax in the text.
The “AnnotatedText” class parses text+markup and converts into plain text and AnnotationTokens.
The annotation token values are injected unchanged alongside the regular text tokens to provide a
form of additional indexed overlay useful in positional searches and highlighting.
Annotated_text fields do not support fielddata as we want to phase this out.
Also includes a new "annotated" highlighter type that retains annotations and merges in search
hits as additional annotation markup.
Closes#29467
The skip_unavailable setting did not exist until 6.1.0. This means that
we need to skip this test on versions prior to 6.1.0. We need to use
this setting because otherwise we will fail startup without it (since we
are not setting up a real remote cluster connection). This commit adds a
skip for all versions prior to 6.1.0.
The change to upgrade cross-cluster search settings was backported to
6.5.0. Therefore, this assumption needs to be reduced to the latest
version where settings were not automatically upgraded.
