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

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

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.

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 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.
The errors were caused because release tests would use a copy of

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

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

With the opening of xpack, we still retained a run task within

license/configuration code for run into the main run configuration.
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

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.
This commit renames IndexLifecycleManager to SecurityIndexManager as it
is not actually a general purpose class, but specific to security. It
also removes indirection in code calling the lifecycle service, instead
calling the security index manager directly.
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
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

* An Analyzer for Korean
* An IntervalQuery and IntervalsSource that retrieve minimum intervals of positional queries.

* 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

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.

xpack core contains a fork of `Cron` from quartz who's javadoc has a

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

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

Where possible I changed the links to the new locations, but in some
circumstances the original ticket was closed (suggesting the awaitsfix

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.
Closes#30156
A few of the old style license got kept around because their comment
string did not start with a space. This caused the license check to not
see it as a license and skip it. This commit cleans it up.
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
