The parser for the Metric config was directly instantiating
the config object, rather than using the builder. That means it was
bypassing the validation logic built into the builder, and would allow
users to create invalid metric configs (like using unsupported metrics).
The job would later blow up and abort due to bad configs, but this isn't
immediately obvious to the user since the PutJob API succeeded.
This change prevents a datafeed using cross cluster search from starting if the remote cluster
does not have x-pack installed and a sufficient license. The check is made only when starting a
datafeed.
Rules allow users to supply a detector with domain
knowledge that can improve the quality of the results.
The model detects statistically anomalous results but it
has no knowledge of the meaning of the values being modelled.
For example, a detector that performs a population analysis
over IP addresses could benefit from a list of IP addresses
that the user knows to be safe. Then anomalous results for
those IP addresses will not be created and will not affect
the quantiles either.
Another example would be a detector looking for anomalies
in the median value of CPU utilization. A user might want
to inform the detector that any results where the actual
value is less than 5 is not interesting.
This commit introduces a `custom_rules` field to the `Detector`.
A detector may have multiple rules which are combined with `or`.
A rule has 3 fields: `actions`, `scope` and `conditions`.
Actions is a list of what should happen when the rule applies.
The current options include `skip_result` and `skip_model_update`.
The default value for `actions` is the `skip_result` action.
Scope is optional and allows for applying filters on any of the
partition/over/by field. When not defined the rule applies to
all series. The `filter_id` needs to be specified to match the id
of the filter to be used. Optionally, the `filter_type` can be specified
as either `include` (default) or `exclude`. When set to `include`
the rule applies to entities that are in the filter. When set to
`exclude` the rule only applies to entities not in the filter.
There may be zero or more conditions. A condition requires `applies_to`,
`operator` and `value` to be specified. The `applies_to` value can be
either `actual`, `typical` or `diff_from_typical` and it specifies
the numerical value to which the condition applies. The `operator`
(`lt`, `lte`, `gt`, `gte`) and `value` complete the definition.
Conditions are combined with `and` and allow to specify numerical
conditions for when a rule applies.
A rule must either have a scope or one or more conditions. Finally,
a rule with scope and conditions applies when all of them apply.
TransportAction has many variants of execute. One of those variants
executes by returning a future, which is then often blocked on by
calling get(). This commit removes this variant of execute, instead
using a helper method for tests that want to block, or having tests
pass in a PlainActionFuture directly as a listener.

* Support RequestedAuthnContext
This implements limited support for RequestedAuthnContext by :
- Allowing SP administrators to define a list of authnContextClassRef
to be included in the RequestedAuthnContext of a SAML Authn Request
- Veirifying that the authnContext in the incoming SAML Asertion's
AuthnStatement contains one of the requested authnContextClassRef
- Only EXACT comparison is supported as the semantics of validating
the incoming authnContextClassRef are deployment dependant and
require pre-established rules for MINIMUM, MAXIMUM and BETTER
Also adds necessary AuthnStatement validation as indicated by [1] and
[2]

Trying to post a new watch without any body currently results in a
NullPointerException. This change fixes that by validating that
Post and Put requests always have a body.
Closes#30057
Allows users of the Low Level REST client to specify which hosts a
request should be run on. They implement the `NodeSelector` interface
or reuse a built in selector like `NOT_MASTER_ONLY` to chose which nodes
are valid. Using it looks like:
```
Request request = new Request("POST", "/foo/_search");
RequestOptions options = request.getOptions().toBuilder();
options.setNodeSelector(NodeSelector.NOT_MASTER_ONLY);
request.setOptions(options);
...
```
This introduces a new `Node` object which contains a `HttpHost` and the
metadata about the host. At this point that metadata is just `version`
and `roles` but I plan to add node attributes in a followup. The
canonical way to **get** this metadata is to use the `Sniffer` to pull
the information from the Elasticsearch cluster.
I've marked this as "breaking-java" because it breaks custom
implementations of `HostsSniffer` by renaming the interface to
`NodesSniffer` and by changing it from returning a `List<HttpHost>` to a
`List<Node>`. It *shouldn't* break anyone else though.
Because we expect to find it useful, this also implements `host_selector`
support to `do` statements in the yaml tests. Using it looks a little
like:
```
---
"example test":
- skip:
features: host_selector
- do:
host_selector:
version: " - 7.0.0" # same syntax as skip
apiname:
something: true
```
The `do` section parses the `version` string into a host selector that
uses the same version comparison logic as the `skip` section. When the
`do` section is executed it passed the off to the `RestClient`, using
the `ElasticsearchHostsSniffer` to sniff the required metadata.
The idea is to use this in mixed version tests to target a specific
version of Elasticsearch so we can be sure about the deprecation
logging though we don't currently have any examples that need it. We do,
however, have at least one open pull request that requires something
like this to properly test it.
Closes#21888
This commit upgrades us to Netty 4.1.25. This upgrade is more
challenging than past upgrades, all because of a new object cleaner
thread that they have added. This thread requires an additional security
permission (set context class loader, needed to avoid leaks in certain
scenarios). Additionally, there is not a clean way to shutdown this
thread which means that the thread can fail thread leak control during
tests. As such, we have to filter this thread from thread leak control.

Make SAML Response Destination check compliant
Only validate the Destination element of an incoming SAML Response
if Destination is present and the SAML Response is signed.
The standard [1] - 3.5.5.2 and [2] - 3.2.2 does mention that the
Destination element is optional and should only be verified when
the SAML Response is signed. Some Identity Provider implementations
are known to not set a Destination XML Attribute in their SAML
responses when those are not signed, so this change also aims to
enhance interoperability.

This is related to #27260 and #28898. This commit adds the transport-nio
plugin as a random option when running the http smoke tests. As part of
this PR, I identified an issue where cors support was not properly
enabled causing these tests to fail when using transport-nio. This
commit also fixes that issue.
Today if a user omits the `_source` entirely or modifies the source
on indexing we have no chance to re-create the document after it has
been added. This is an issue for CCR and recovery based on soft deletes
which we are going to make the default. This change adds an additional
recovery source if the source is disabled or modified that is only kept
around until the document leaves the retention policy window.
This change adds a merge policy that efficiently removes this extra source
on merge for all document that are live and not in the retention policy window
anymore.
This commit adjusts the indentation in the CLI scripts to give a clear
visual indication that the line being indented is a continuation of the
previous line.
SSLTrustRestrictionsTests updates the restrictions YML file during the test run to change the set of restrictions. This update was small, but it wasn't atomic.
If the yml file is reloaded while empty or invalid, then it causes all SSL certificates to be considered invalid (until it is reloaded again), which could break the sniffing/administrative client that runs underneath the tests.
A previous refactoring of the CLI scripts migrated all of the CLI tools
to shell to a common script, elasticsearch-cli. This approach is fine in
Bash where it is easy to tear arguments apart but it doesn't work so
well on Windows where quoting is insane. To avoid having to tear the
arguments apart to separate the first argument to elasticsearch-cli from
the remaining arguments, we instead choose a strategy where we can avoid
tearing the arguments apart. To do this, we will instead pass the main
class by an environment variable and then we can pass the arguments
straight through. This will let us avoid awful quoting issues on
Windows. This is the Windows side of that effort and the Bash side was
in a previous commit.

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.
The primary shard copy on the following has authority of the replication
operations that occur on the following side in cross-cluster
replication. Yet today we are using the primary term directly from the
operations on the leader side. Instead we should be replacing the
primary term on the following side with the primary term of the primary
on the following side. This commit does this by copying the translog
operations with the corrected primary term. This ensures that we use
this primary term while applying the operations on the primary, and when
replicating them across to the replica (where the replica request was
carrying the primary term of the primary shard copy on the follower).
The native realm's usage stats were previously pulled from the cache,
which only contains the number of users that had authenticated in the
past 20 minutes. This commit changes this so that we pull the current
value from the security index by executing a search request. In order
to support this, the usage stats for realms is now asynchronous so that
we do not block while waiting on the search to complete.
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.
The old perform request methods on the REST client have been deprecated
in favor using request-flavored methods. This commit addresses the use
of these deprecated methods in the CCR test suite.
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)
Relates to #23658
This commit adds a check that any class in X-Pack that is a feature
aware custom also implements the appropriate mix-in interface in
X-Pack. These interfaces provide a default implementation of
FeatureAware#getRequiredFeature that returns that x-pack is the required
feature. By implementing this interface, this gives a consistent way for
X-Pack feature aware customs to return the appopriate required feature
and this check enforces that all such feature aware customs return the
appropriate required feature.

We should not allow the user to configure index patterns that also match

This will start throwing errors as soon as the rollup index is created
because the indexer will try to search it.
Note: this does not prevent the user from matching against existing
rollup indices. That should be prevented by the field-level validation
during job creation.

Extends ActionRequestValidationException with a rollup-specific version

instead of `action_request_validation_exception`
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.
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.

Core: Remove RequestBuilder from Action (#30966)
If you invoke elasticsearch-plugin (or any other CLI script on Windows)
with a path that has a percent-encoded space (or any other
percent-encoded character) because the CLI scripts now shell into a
common shell script (elasticsearch-cli) the percent-encoded space ends
up being interpreted as a parameter. For example passing install --batch
file:/c:/encoded%20%space/analysis-icu-7.0.0.zip to elasticsearch-plugin
leads to the %20 being interpreted as %2 followed by a zero. Here, the
%2 is interpreted as the second parameter (--batch) and the
InstallPluginCommand class ends up seeing
file:/c/encoded--batch0space/analysis-icu-7.0.0.zip as the path which
will not exist. This commit addresses this by escaping the %* that is
used to pass the parameters to the common CLI script so that the common
script sees the correct parameters without the %2 being substituted.
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.

Otherwise we could end up with persistent tasks metadata in the cluster that some of the nodes
might not understand in case where the cluster is during rolling upgrade from the default 6.2 to the
default 6.3 distribution.

Today before reading operations on the leading shard, we minimization
the requesting range with the global checkpoint. However, this might
make the request invalid if the following shard generates a requesting
range based on the global-checkpoint from a primary shard and sends
that request to a replica whose global checkpoint is lagged.
Another issue is that we are mutating the request when applying
minimization. If the request becomes invalid on a replica, we will
reroute the mutated request instead of the original one to the primary.
This commit removes the minimization and replaces it by a range check
with the local checkpoint.
* Ensure that a purposefully wrong key is used
Uses a specific keypair for tests that require a purposefully wrong
keypair instead of selecting one randomly from the same pull from
which the correct one is selected. Entropy is low because of the
small space and the same key can be randomly selected as both the
correct one and the wrong one, causing the tests to fail.
The purposefully wrong key is also used in
testSigningKeyIsReloadedForEachRequest and needs to be cleaned
up afterwards so the rest of the tests don't use that for signing.
Resolves#30970
This commit removes the RequestBuilder generic type from Action. It was
needed to be used by the newRequest method, which in turn was used by
client.prepareExecute. Both of these methods are now removed, along with
the existing users of prepareExecute constructing the appropriate
builder directly.
This commit reworks the Sniffer component to simplify it and make it possible to test it.
In particular, it no longer takes out the host that failed when sniffing on failure, but rather relies on whatever the cluster returns. This is the result of some valid comments from #27985. Taking out one single host is too naive, hard to test and debug.
A new Scheduler abstraction is introduced to abstract the tasks scheduling away and make it possible to plug in any test implementation and take out timing aspects when testing.
Concurrency aspects have also been improved, synchronized methods are no longer required. At the same time, we were able to take #27697 and #25701 into account and fix them, especially now that we can more easily add tests.
Last but not least, unit tests are added for the Sniffer component, long overdue.

The shard changes api returns the minimum IndexMetadata version the leader
index needs to have. If the leader side is behind on IndexMetadata version
then follow shard task waits with processing write operations until the
mapping has been fetched from leader index and applied in follower index
in the background.
The cluster state api is used to fetch the leader mapping and put mapping api
to apply the mapping in the follower index. This works because put mapping
api accepts fields that are already defined.

Removes the last remaining server dependencies from jdbc client. In order to do that it introduces the new project sql-shared-proto that contains only XContent-serializable classes. HTTP Client and JDBC now depend only on sql-shared-proto. I had to keep the original sql-proto project since it is used as a dependency by sql-cli and security integration tests.
Relates #29856
This is a bug that was identified by the kibana team. Currently on a
get-license call we do not serialize the hard-coded expiration for basic
licenses. However, the kibana team calls the x-pack info route which
still does serialize the expiration date. This commit removes that
serialization in the rest response.

Currently nio and netty modules use the CompletableFuture class for
managing listeners. This is unfortunate as that class accepts
Throwable. This commit adds a class CompletableContext that wraps
the CompletableFuture but does not accept Throwable. This allows the
modification of netty and nio logic to no longer handle Throwable.
This commit reworks the way our realms perform caching in order to
limit each principal to a single ongoing authentication per realm. In
other words, this means that multiple requests made by the same user
will not trigger more that one authentication attempt at a time if no
entry has been stored in the cache. If an entry is present in our
cache, there is no restriction on the number of concurrent
authentications performed for this user.
This change enables us to limit the load we place on an external system
like an LDAP server and also preserve resources such as CPU on
expensive operations such as BCrypt authentication.
Closes#30355
This commit fixes an issue with dynamic mapping updates when an index
operation is performed against an alias and when the user only has
permissions to the alias. Dynamic mapping updates resolve the concrete
index early to prevent issues so the information about the alias that
the triggering operation was being executed against is lost. When
security is enabled and a user only has privileges to the alias, this
dynamic mapping update would be rejected as it is executing against the
concrete index and not the alias. In order to handle this situation,
the security code needs to look at the concrete index and the
authorized indices of the user; if the concrete index is not authorized
the code will attempt to find an alias that the user has permissions to
update the mappings of.
Closes#30597
The .watcher-history-* template is currently using a plugin-custom index setting xpack.watcher.template.version,
which prevents this template from being installed in a mixed OSS / X-Pack cluster, ultimately
leading to the situation where an X-Pack node is constantly spamming an OSS master with (failed)
template updates. Other X-Pack templates (e.g. security-index-template or security_audit_log)
achieve the same versioning functionality by using a custom _meta field in the mapping instead.
This commit switches the .watcher-history-* template to use the _meta field instead.
Persistent tasks was moved from X-Pack to core in #28455.
However, registration of the named writables and named
X-content was left in X-Pack.
This change moves the registration of the named writables
and named X-content into core. Additionally, the persistent
task actions are no longer registered in the X-Pack client
plugin, as they are already registered in ActionModule.
This change adds a simple header to the transport client
that is present on the servers thread context that ensures
we can detect if a transport client talks to the server in a
specific request. This change also adds a header for xpack
to detect if the client has xpack installed.

Closes#27740
Enables a rolling restart from the OSS distribution to the x-pack based distribution by preventing
x-pack code from installing custom metadata into the cluster state until all nodes are capable of
deserializing this metadata.
When doing a node restart using the test framework, the restarted node does not only use the
settings provided to the original node, but also additional settings provided by plugin extensions,
which does not correspond to the settings that a node would have on a true restart.
This is related to #29500. We are removing the ability to disable http
pipelining. This PR removes the references to disabling pipelining in
the integration test case.

This commit changes the wait for a few netty threads to wait for these
threads to complete after the cluster has stopped. Previously, we were
waiting for these threads before the cluster was actually stopped; the
cluster is stopped in an AfterClass method of ESIntegTestCase, while
the wait was performed in the AfterClass of a class that extended
ESIntegTestCase, which is always executed before the AfterClass of
ESIntegTestCase.
Now, the wait is contained in an ExternalResource ClassRule that
implements the waiting for the threads to terminate in the after
method. This rule is executed after the AfterClass method in
ESIntegTestCase. The same fix has also been applied in
SecuritySingleNodeTestCase.
Closes#30563
Prior to this change an json array element with no fields would be omitted from json array.
Nested inner hits source filtering relies on the fact that the json array element numbering
remains untouched and this causes AOOB exceptions in the ES side during the fetch phase

This is related to #27260. The elasticsearch-nio jar is supposed to be

Fix#29685
This change is to support rolling upgrade from a pre-6.3 default
distribution (i.e. without X-Pack) to a 6.3+ default distribution
(i.e. with X-Pack).
The ML metadata is no longer eagerly added to the cluster state
as soon as the master node has X-Pack available. Instead, it
is added when the first ML job is created.
As a result all methods that get the ML metadata need to be able
to handle the situation where there is no ML metadata in the
current cluster state. They do this by behaving as though an
empty ML metadata was present. This logic is encapsulated by
always asking for the current ML metadata using a static method
on the MlMetadata class.

diskspace and creates a subfolder for storing data outside of Lucene
indexes, but as part of the ES data paths.
Details:
- tmp storage is managed and does not allow allocation if disk space is
below a threshold (5GB at the moment)
- tmp storage is supposed to be managed by the native component but in
case this fails cleanup is provided:
- on job close
- on process crash
- after node crash, on restart
- available space is re-checked for every forecast call (the native
component has to check again before writing)
Note: The 1st path that has enough space is chosen on job open (job
close/reopen triggers a new search)
Watcher tests now always fail hard when watches that were
tried to be triggered in a test using the trigger() method,
but could not because they were not found on any of the
nodes in the cluster.
This change adds version information in case a native ML process crashes, the version is important for choosing the right symbol files when analyzing the crash. Adding the version combines all necessary information on one line.

It is possible for state documents to be
left behind in the state index. This may be
because of bugs or uncontrollable scenarios.
In any case, those documents may take up quite
some disk space when they add up. This commit
adds a step in the expired data deletion that
is part of the daily maintenance service. The
new step searches for state documents that
do not belong to any of the current jobs and
deletes them.

Adjust fast forward for token expiration test
Adjusts the maximum fast forward time for token expiration tests

Resolves: #30062
The part of the history template responsible for slack attachments had a
dynamic mapping configured which could lead to problems, when a string
value looking like a date was configured in the value field of an
attachment.
This commit fixes the template by setting this field always to text.
This also requires a change in the template numbering to be sure this
will be applied properly when starting watcher.

* Refactors ClientHelper to combine header logic
This change removes all the `*ClientHelper` classes which were
repeating logic between plugins and instead adds
`ClientHelper.executeWithHeaders()` and
`ClientHelper.executeWithHeadersAsync()` methods to centralise the
logic for executing requests with stored security headers.
* Removes Watcher headers constant
When the encrpytion of sensitive date is enabled, test that a
scheduled watch is executed as expected and produces the correct value
from a secret in the basic auth header.
The TODOs in the rest actions was incorrect. The problem was that
these rest actions used `follow_index` as first named variable in the path
under which the rest actions were registered. Other candidate rest actions that
also have a named variable as first element in the path (but with a different
name) get resolved as rest parameters too and passed down to the rest
action that actually ends up getting executed.
In the case of the follow index api, a `index` parameter got passed down
to `RestFollowExistingAction`, but that param was never used. This caused the
follow index api call to fail, because of unused http parameters.
This change doesn't fixes that problem, but works around it by using
`index` as named variable for the follow index (instead of `follow_index`).
Relates to #30102
If security is enabled today with ccr then the follow index api will
fail with the fact that system user does not have privileges to use
the shard changes api. The reason that system user is used is because
the persistent tasks that keep the shards in sync runs in the background
and the user that invokes the follow index api only start those background
processes.
I think it is better that the system user isn't used by the persistent
tasks that keep shards in sync, but rather runs as the same user that
invoked the follow index api and use the permissions that that user has.
This is what this PR does, and this is done by keeping track of
security headers inside the persistent task (similar to how rollup does this).
This PR also adds a cluster ccr priviledge that allows a user to follow
or unfollow an index. Finally if a user that wants to follow an index,
it needs to have read and monitor privileges on the leader index and
monitor and write privileges on the follow index.
Make SSLContext reloadable
This commit replaces all customKeyManagers and TrustManagers
(ReloadableKeyManager,ReloadableTrustManager,
EmptyKeyManager, EmptyTrustManager) with instances of
X509ExtendedKeyManager and X509ExtendedTrustManager.
This change was triggered by the effort to allow Elasticsearch to
run in a FIPS-140 environment. In JVMs running in FIPS approved
mode, only SunJSSE TrustManagers and KeyManagers can be used.
Reloadability is now ensured by a volatile instance of SSLContext
in SSLContectHolder.
SSLConfigurationReloaderTests use the reloadable SSLContext to
initialize HTTP Clients and Servers and use these for testing the
key material and trust relations.
This commit is related to #28898. It adds an nio driven http server
transport. Currently it only supports basic http features. Cors,
pipeling, and read timeouts will need to be added in future PRs.
Due to the way composite aggregation works, ordering in GROUP BY can be

Fix 29900
This commit removes the SecurityLifecycleService, relegating its former
functions of listening for cluster state updates to SecurityIndexManager
and IndexAuditTrail.
This change adds a grok_pattern field to the GET categories API
output in ML. It's calculated using the regex and examples in the
categorization result, and applying a list of candidate Grok
patterns to the bits in between the tokens that are considered to
define the category.
This can currently be considered a prototype, as the Grok patterns
it produces are not optimal. However, enough people have said it
would be useful for it to be worthwhile exposing it as experimental
functionality for interested parties to try out.
This is fixing an issue that has come up in some builds. In some
scenarios I see an assertion failure that we are trying to move to
application mode when we are not in handshake mode. What I think is
happening is that we are in handshake mode and have received the
completed handshake message AND an application message. While reading in
handshake mode we switch to application mode. However, there is still
data to be consumed so we attempt to continue to read in handshake mode.
This leads to us attempting to move to application mode again throwing
an assertion.
This commit fixes this by immediatly exiting the handshake mode read
method if we are not longer in handshake mode. Additionally if we swap
modes during a read we attempt to read with the new mode to see if there
is data that needs to be handled.

This commit cleans up some code in the FileUserPasswdStore and the
FileUserRolesStore classes. The maps used in these classes are volatile
so we need to make sure that we don't perform multiple operations with
the map unless we are sure we are using a reference to the same map.
The maps are also never null, but there were a few null checks in the
code that were not needed. These checks have been removed.
The TokenMetaData equals method compared byte arrays using `.equals` on
the arrays themselves, which is the equivalent of an `==` check. This
means that a seperate byte[] with the same contents would not be
considered equivalent to the existing one, even though it should be.
The method has been updated to use `Array#equals` and similarly the
hashcode method has been updated to call `Arrays#hashCode` instead of
calling hashcode on the array itself.
These tests are both in the file `watcher/stats/10_basic`, and have been
failing fairly frequently over the last month with a start-up issue.
The issue is being tracked in #30298.
Dates internally contain milliseconds (which appear when converting them
to Strings) however parsing does not accept them (and is being strict).
The parser has been changed so that Date is mandatory but the time
(including its fractions such as millis) are optional.

This commit adds a general state listener to the SecurityIndexManager,
and replaces the existing health and up-to-date listeners with that. It
also moves helper methods relating to health to SecurityIndexManager
from SecurityLifecycleService.
As conformance to best practices, this changes ensures that if a
SAML Response is signed, we verify the signature before processing
it any further. We were only checking the InResponseTo and
Destination attributes before potential signature validation but
there was no reason to do that up front either.
With the opening of xpack, we still retained a run task within
:x-pack:plugin. However, the root level run task also runs with the
default distribution. This change removes the extra run task inside
xpack in favor of using the root level task, and moves the
license/configuration code for run into the main run configuration.
This commit adds an API to read translog snapshot from Lucene,
then cut-over from the existing translog to the new API in CCR.

This commit removes the hardcoded list of unconfigured ciphers in the
SslIntegrationTests. This list may include ciphers that are not
supported on certain JVMs. This list is replaced with code that
dynamically computes the set of ciphers that are not configured for
use by default.
The HTTPClient used in watcher is based on the apache http client. The
current client is using a lot of defaults - which are not always
optimal. Two of those defaults are the maximum number of total
connections and the maximum number of connections to a single route.
If one of those limits is reached, the HTTPClient waits for a connection
to be finished thus acting in a blocking fashion. In order to prevent
this when many requests are being executed, we increase the limit of
total connections as well as the connections per route (a route is
basically an endpoint, which also contains proxy information, not
containing an URL, just hosts).
On top of that an additional option has been set to evict
long running connections, which can potentially be reused after some
time. As this requires an additional background thread, this required
some changes to ensure that the httpclient is closed properly. Also the
timeout for this can be configured.

Watcher: Remove unneeded index deletion in tests
Starting watcher should wait for the watcher to be started before
marking the status as started, which is now done via a callback.
Also, reloading watcher could set the execution service to paused. This could
lead to watches not being executed, when run in tests. This fix does not
change the paused flag in the execution service, just clears out the
current queue and executions.
Closes#30381
[CCR] added rest specs and simple rest test for follow and unfollow apis, also
Added an acknowledge field in follow and unfollow api responses. Currently these api return an empty response and fixed bug in unfollow api that didn't cleanup node tasks properly.
When validating the search request, we make sure any date_histogram
aggregations have timezones that match the jobs. But we didn't
do any such validation on range queries.
While it wouldn't produce incorrect results, it would be confusing
to the user as no documents would match the aggregation (because we
add a filter clause on the timezone for the agg).
Now the user gets an exception up front, and some helpful text about
why the range query didnt match, and which timezones are acceptable

Upgrade to lucene-7.4.0-snapshot-1ed95c097b
This version contains:
* An Analyzer for Korean
* An IntervalQuery and IntervalsSource that retrieve minimum intervals of positional queries.
* A new API to retrieve matches (offsets and positions) of a query for a single document.
* Support for soft deletes in the index writer.
* A fixed shingle filter that handles index time synonyms.
* Support for emoji sequence in ICUTokenizer (with an upgrade to icu 61.1)
When the watcher service pauses execution due to a cluster state update,
the trigger service and its engines also need to pause properly instead
of keeping going. This is also important when the .watches index is
deleted, so that watches don't stay in a triggered mode.
The IndexAndAliasesResolver resolves the indices and aliases for each
request and also handles local and remote indices. The current
implementation uses the ResolvedIndices class to hold the resolved
indices and aliases. While evaluating the indices and aliases against
the user's permissions, the final value for ResolvedIndices is
constructed. Prior to this change, this was done by creating a
ResolvedIndices for the first set of indices and for each additional
addition, a new ResolvedIndices object is created and merged with
the existing one. With a small number of indices and aliases this does
not pose a large problem; however as the number of indices/aliases
grows more list allocations and array copies are needed resulting in a
large amount of garbage and severely impacted performance.
This change introduces a builder for ResolvedIndices that appends to
mutable lists until the final value has been constructed, which will
ultimately reduce the amount of garbage generated by this code.
When dealing with filtering, a composite aggregation might return empty
buckets (which have been filtered) which gets sent as is to the client.
Unfortunately this interprets the response as no more data instead of
retrying.
This now has changed and the listener keeps retrying until either the
query has ended or data passes the filter.
Fix#30292
This commit fixes an issue with the data diagnostics were
empty buckets are not reported even though they should. Once
a job is reopened, the diagnostics do not get initialized from
the current data counts (especially the latest record timestamp).
The result is that if the data that is sent have a time gap compared
to the previous ones, that gap is not accounted for in the empty bucket
count.
This commit fixes that by initializing the diagnostics with the current
data counts.
Closes#30080
The current implementation starts/stops watcher using an executor. This
can result in our of order operations.
This commit reduces those executor calls to an absolute minimum in order
to be able to do state changes within the cluster state listener method,
which runs in sequence.
When a state change occurs that forces the watcher service to pause
(like no watcher index, no master node, no local shards), the service is
now in a paused state.
Pausing is a super lightweight operation, which marks the
ExecutionService as paused and waits for the currently executing watches
to finish in the background via an executor. The same applies for
stopping, the potentially long running operation is outsourced in to an
executor, as waiting for executed watches is decoupled from the current
state.
The only other long running operation is starting, where watches need to
be loaded. This is also done via an executor, but has an additional
protection by checking the cluster state version it was started with. If
another cluster state version was trying to load the watches, then this
loading will not take effect.
This PR also cleans up some unused states, like the a simple boolean in
the HistoryStore/TriggeredWatchStore marking it as started or stopped,
as this can now be caught in the execution service.
Another advantage of this approach is the fact, that now only triggered
watches are not getting executed, while watches that are run via the
Execute Watch API will still be executed regardless if watcher is
stopped or not.
Lastly the TickerScheduleTriggerEngine thread now only starts on data nodes.
This commit is a follow up to #30135. It updates the stream
compatibility versions in the start_trial requests and responses to
reflect that fact that this work has been backported to 6.3.
Necessary changes so that the licensing functionality can be
used in a JVM in FIPS 140 approved mode.
* Uses adequate salt length in encryption
* Changes key derivation to PBKDF2WithHmacSHA512 from a custom
approach with SHA512 and manual key stretching
* Removes redundant manual padding
Other relevant changes:
* Uses the SAH512 hash instead of the encrypted key bytes as the
key fingerprint to be included in the license specification
* Removes the explicit verification check of the encryption key
as this is implicitly checked in signature verification.
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.
closes#12792
* SQL: Reduce number of ranges generated for comparisons
Rewrote optimization rule for combining ranges by improving the
detection of binary comparisons in a tree to better combine
them in a range, regardless of their place inside an expression.
Additionally, improve the comparisons of Numbers of different types
Also, improve reassembly of conjunction/disjunction into balanced
trees.
Do not promote BinaryComparisons to Ranges since it introduces NULL
boundaries and thus a corner-case that needs too much handling
Compare BinaryComparisons directly between themselves and to Ranges

The elasticsearch-users utility had various messages that were

The variadic constructor was only used in a few places and the
RepositoriesMetaData class is backed by a List anyway, so just using a

xpack core contains a fork of `Cron` from quartz who's javadoc has a
`<table>` with non-html5 compatible stuff. This html5ifies the table and
switches the `:x-pack:plugin:core` project to building javadoc with
HTML5.
This commit refactors the DataStreamDiagnostics class
achieving the following advantages:
- simpler code; by encapsulating the moving bucket histogram
into its own class
- better performance; by using an array to store the buckets
instead of a map
- explicit handling of gap buckets; in preparation of fixing #30080
Starting with the refactoring in https://github.com/elastic/elasticsearch/pull/22778 (released in 5.3) we may fail to properly replicate operation when a mapping update on master fails. If a bulk
operations needs a mapping update half way, it will send a request to the master before continuing
to index the operations. If that request times out or isn't acked (i.e., even one node in the cluster
didn't process it within 30s), we end up throwing the exception and aborting the entire bulk. This is
a problem because all operations that were processed so far are not replicated any more to the
replicas. Although these operations were never "acked" to the user (we threw an error) it cause the
local checkpoint on the replicas to lag (on 6.x) and the primary and replica to diverge.
This PR does a couple of things:
1) Most importantly, treat *any* mapping update failure as a document level failure, meaning only
the relevant indexing operation will fail.
2) Removes the mapping update callbacks from `IndexShard.applyIndexOperationOnPrimary` and
similar methods for simpler execution. We don't use exceptions any more when a mapping
update was successful.
I think we need to do more work here (the fact that a single slow node can prevent those mappings
updates from being acked and thus fail operations is bad), but I want to keep this as small as I can
(it is already too big).
The overall NOTICE file for the ML X-Pack module should
include the notices from the 3rd party C++ components as
well as the 3rd party Java components.
Currently, the only way to get the REST response for the `/_cluster/state`
call to return the `cluster_uuid` is to request the `metadata` metrics,
which is one of the most expensive response structures. However, external
monitoring agents will likely want the `cluster_uuid` to correlate the
response with other API responses whether or not they want cluster
metadata.
We had a number of awaitsFix links that weren't updated after the xpack
merge.
Where possible I changed the links to the new locations, but in some
circumstances the original ticket was closed (suggesting the awaitsfix
should be removed) or was otherwise unclear the status.

Email message IDs are supposed to be unique. In order to guarantee this,
we need to take the action id of a watch action into account as well,
not just the watch id from the watch execution context. This prevents
that two actions from the same watch execution end up with the same
message id.
This is related to #30134. It modifies the start_trial action to require
an acknowledgement parameter in the rest request to actually start the
trial license. There are backwards compatibility issues as prior ES
versions did not support this parameter. To handle this, it is assumed
that a request coming from a node prior to 6.3 is acknowledged. And
attempts to write a non-acknowledged request to a prior to 6.3 node will
throw an exception.
Additionally this PR adds messages about the trial license the user is
generating.
Currently the test picks random java.util.TimeZone ids in some places.
Internally we still need to convert back to joda DateTimeZone by id
occassionally (e.g. when serializing to pre 6.3 versions). There are
some deprecated "SystemV/*" time zones that Jodas DateTimeZone refuses
to convert. This change excludes those rare cases from the set of
allowed random time zones. It would be quiet odd for them to appear in
practice.

[Docs] Add community analysis plugin (#29612)
Adds tasks that check that the all jars that we build have LICENSE.txt
and NOTICE.txt files and that the files are correct. Sets check to
depend on these task.
This is mostly there for extra parnoia because we automatically
configure all Jar tasks to include the LICENSE.txt and NOTICE.txt
files anyway. But it is quite possible to add configuration to those
tasks that would override either file.
This causes check to depend on several more things than it used to.
Take, for example, javadoc:
check depends on the new verifyJavadocJarNotice which depends on
extractJavadocJar which depends on javadocJar which depends on
javadoc, this check now depends on javadoc.
The bundled configuration isn't recognised by eclipse so these
dependencies are missed when it imports the `x-pack:plugin:sql:jdbc`
project. This change makes these dependencies compile dependencies if
the build is running for Eclipse.
Tests need to wait for changes to the job's established memory usage to
propagate and an over enthusiastic optimisation meant jobs were updated
from stale state causing recent change to be lost.
This commit fixes the classpath for the SQL CLI tool on Windows. As the
x-pack bin folder was collapsed into the distribution bin folder, the
location of the classpath here needed to no longer contain the old
plugins directory.
This commit adds the distribution type to the startup scripts so that we
can discern from log output and the main response the type of the
distribution (deb/rpm/tar/zip).
With the move of X-Pack to a module, the classpath for the scripts needs
to be adjusted. This was done on Unix, but not for Windows. This commit
addresses Windows.
This commit adds the distribution flavor (default versus oss) to the
build process which is passed through the startup scripts to
Elasticsearch. This change will be used to customize the message on
attempting to install/remove x-pack based on the distribution flavor.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
The follow index api completely reuses CCS infrastructure that was exposed via:
https://github.com/elastic/elasticsearch/pull/29495
This means that the leader index parameter support the same ccs index
to indicate that an index resides in a different cluster.
I also added a qa module that smoke tests the cross cluster nature of ccr.
The idea is that this test just verifies that ccr can read data from a
remote leader index and that is it, no crazy randomization or indirectly
testing other features.
keep track of shard follow stats inside shard follow stats' node task instead of persistent task status.
By maintaining the shard follow stats inside its node task the stats update is quicker as
no cluster state update is required. The stats are now transient; meaning if the task
is going to run a different node then the stats are gone too. Currently only the processed
global checkpoint is being tracked and this is being restored when a shard follow node task
starts via the indices stats api (the reason of the first change of this change). Other stats
that we may add in the future (like fetch_time, see: https://gist.github.com/s1monw/dba13daf8493bf48431b72365e110717)
it is ok if we start from zero in case a shard follow task moves to another node.
This limit is based on the number of estimate bytes in each translog
operation that fall between the minimum and maximum request sequence number.
If this limit is met then the shard follow task executor will make sure
that a subsequent shard changes request will be performed to fetch the
remaining translog operations.
This limit is needed in order to protect against returning too many
translog operations in a single shard changes response.
