Adding to #55659, we missed another way we could set the task to
failed due to task cancellation. CI revealed that we might also
get a `SearchPhaseExecutionException` whose cause is a
`TaskCancelledException`. That exception is not wrapped so
unwrapping it will not return the underlying `TaskCancelledException`.
Thus to be complete in catching this, we also need to check the
error's cause.

This is a continuation from #55580.
Now that we're parsing phase progresses from the analytics process
we change `ProgressTracker` to allow for custom phases between
the `loading_data` and `writing_results` phases. Each `DataFrameAnalysis`
may declare its own phases.
This commit sets things in place for the analytics process to start
reporting different phases per analysis type. However, this is
still preserving existing behaviour as all analyses currently
declare a single `analyzing` phase.

This change adds validation when running the users tool so that
if Elasticsearch is expected to run in a JVM that is configured to
be in FIPS 140 mode and the password hashing algorithm is not
compliant, we would throw an error.
Users tool uses the configuration from the node and this validation
would also happen upon node startup but users might be added in the
file realm before the node is started and we would have the
opportunity to notify the user of this misconfiguration.
The changes in #55544 make this much less probable to happen in 8
since the default algorithm will be compliant but this change can
act as a fallback in anycase and makes for a better user experience.
Our handling for concurrent refresh of access tokens suffered from
a race condition where:
1. Thread A has just finished with updating the existing token
document, but hasn't stored the new tokens in a new document
yet
2. Thread B attempts to refresh the same token and since the
original token document is marked as refreshed, it decrypts and
gets the new access token and refresh token and returns that to
the caller of the API.
3. The caller attempts to use the newly refreshed access token
immediately and gets an authentication error since thread A still
hasn't finished writing the document.
This commit changes the behavior so that Thread B, would first try
to do a Get request for the token document where it expects that
the access token it decrypted is stored(with exponential backoff )
and will not respond until it can verify that it reads it in the
tokens index. That ensures that we only ever return tokens in a
response if they are already valid and can be used immediately
It also adjusts TokenAuthIntegTests
to test authenticating with the tokens each thread receives,
which would fail without the fix.
Resolves: #54289
The failed_category_count statistic records the number of times
categorization wanted to create a new category but couldn't
because the job had reached its model_memory_limit.

This commit refactors all spatial Field Mappers to a common
AbstractGeometryFieldMapper that implements shared parameter functionality
(e.g., ignore_malformed, ignore_z_value) and provides a common framework for
overriding type parsing, and building in xpack. Common shape functionality is
implemented in a new AbstractShapeGeometryFieldMapper that is reused and
overridden in GeoShapeFieldMapper, GeoShapeFieldMapperWithDocValues,
LegacyGeoShapeFieldMapper, and ShapeFieldMapper. This abstraction provides a
reusable foundation for adding new xpack features; such as coordinate reference
system support.
This commit removes some code duplication in the CCR non-compliance
tests by refactoring an assertion method so that it can be used in both
tests that are present there.
Since #55580 we've introduced a new format for parsing progress
from the data frame analytics process. As the process is now
writing out progress in this new way, we can remove the parsing
of the old format.
Backport of #55711
If we choose to read from two random positions that are 1024 bytes apart then
this counts as a contiguous read for stats purposes, failing this test. This
commit ensures that we always perform a non-contiguous read.
`SearchableSnapshotDirectoryStatsTests#testCachedBytesReadsAndWrites` asserts
that each write takes one clock tick, but we now permit concurrent reads and
writes so each write might take longer. This commit relaxes the assertion to
match.
Closes#55707

improve tests related to stopping using a client that answers and can be
synchronized with the test thread in order to test special situations
relates #55011
This commit fixes reproducible test failures with the
SSLReloadDuringStartupIntegTests on the 7.x branch. The failures only
occur on 7.x due to the existence of the transport client and its usage
in our test infrastructure. This change removes the randomized usage of
transport clients when retrieving a client from a node in the internal
cluster. Transport clients do not support the reloading of files for
TLS configuration changes but if we build one from the nodes settings
and attempt to use it after the files have been changed, the client
will not know about the changes and the TLS connection will fail.
Closes#55524
License state is currently made up of boolean methods that check whether
a particular feature is allowed by the current license state. Each new
feature must copy/past boiler plate code. While that has gotten easier
with utilities like isAllowedByLicense, this is still more cumbersome
than should be necessary. This commit adds a general purpose isAllowed
method which takes a new Feature enum, where each value of the enum
defines the minimum license mode and whether the license must be active
to be allowed. Only security features are converted in this PR, in order
to keep the commit size relatively small. The rest of the features will
be converted in a followup.
This adds a validation to VSParserHelper to ensure that a field or
script or both are specified by the user. This is technically
required today already, but throws an exception much deeper
in the agg framework and has a very unintuitive error for the user
(as well as eating more resources instead of failing early)
The (de)serialization code of the async search response
cannot handle exceptions that extend ElasticsearchException (e.g. ScriptException).
This commit fixes this bug by serializing the error with the more generic
StreamInput#writeException.
EQL will require very similar functionality to async search. This PR refactors
AsyncSearchIndexService to make it reusable for EQL.

This commit refactors geo_shape doc values, fielddata, and utility classes from
the single mapper package in x-pack spatial plugin to a package structure that
is consistent with the server module.
Previously audit messages were indexed when datafeeds that were
assigned to a node were stopped, but not datafeeds that were
unassigned at the time they were stopped.
This change adds auditing for the unassigned case.
Backport of #55656
While we were catching `TaskCancelledException` while we wait for
reindexing to complete, we missed the fact that this exception
may be wrapped in a multi-node cluster. This is the reason
we may still fail the task when stop is called while reindexing.
Some times we're lucky and the exception is thrown by the same
node that runs the job. Then the exception is not wrapped and
things work fine. But when that is not the case the exception is
wrapped, we fail to catch it, and set the task to failed.
The fix is to simply unwrap the exception when we check it it
is `TaskCancelledException`.
Closes#55068

The CacheFile.fileLock() method is used to acquire a lock
on a cache file so that the file can't be deleted (or its file
handle closed) during the execution of a read or a write
operation.
Today this lock is obtained by first acquiring the eviction
lock (the write lock of the readwrite lock), then by checking
if the cache file is evicted and the file channel still open,
and finally by obtaining the file lock (the read lock of the
readwrite lock). Acquiring the read lock while the eviction
lock is held ensures that the cache file eviction cannot
start in the meanwhile. But eviction starts (and terminations)
also acquire the eviction lock; and this lock cannot be
obtained while a read lock is held (the write lock of a
readwrite lock is exclusive).
If we were acquiring a read lock and checking the eviction
flag and file channel existence while holding the read lock
we know that no eviction can start or finish until the
read lock is released.
Backport of #55115.
Replace calls to deprecate(String,Object...) with deprecateAndMaybeLog(...),
with an appropriate key, so that all messages can potentially be deduplicated.
The Kibana CSV export feature uses a non-standard timestamp format.
This change adds it to the formats the find_file_structure endpoint
recognizes out-of-the-box, to make round-tripping data from Kibana
back to Kibana via CSV files easier.

A JSON schema was recently introduced for the REST API specification. #54252
This PR introduces a 3rd party validation tool to ensure that the
REST specification conforms to the schema.
The task is applied to the 3 projects that contain REST API specifications.
The plugin wires this task into the precommit commit task, and should be
considered as part of the public API for the build tools for any plugin
developer to contribute their plugin's specification.
An ignore parameter has been introduced for the task to allow specific
file to be ignored from the validation. The ignored files in this PR
will soon get issues logged and a link so they can be fixed.
Closes#54314
Out of the box "access granted" audit events are not logged
for system users. The list of system users was stale and included
only the _system and _xpack users. This commit expands this list
with _xpack_security and _async_search, effectively reducing the
auditing noise by not logging the audit events of these system
users out of the box.
Closes#37924
The testPerformAction test has been failing periodically due to
how Hamcrest's containsStringIgnoringCase does not lowercase using
the same Locale set in the test infrastructure.
This commit falls back to explicitly lowercasing using the root
locale
This commit adds a new GeoShapeBoundsAggregator to the spatial plugin and registers it with the GeoShapeValuesSourceType. This enables geo_bounds aggregations on geo_shape fields
After #53562, the `geo_shape` field mapper is registered within
a module. This opens the door for introducing a new `geo_shape`
field mapper into the Spatial Plugin that has doc-values support.
This is very much an extension of server's GeoShapeFieldMapper,
but with the addition of the doc values implementation.
Data frame analytics process currently reports progress as
an integer `progress_percent`. We parse that and report it
from the _stats API as the progress of the `analyzing` phase.
However, we want to allow the DFA process to report progress
for more than one phase. This commit prepares for this by
parsing `phase_progress` from the process, an object that
contains the `phase` name plus the `progress_percent` for that
phase.
Backport of #55580
Instead of doing our own checks against REST status, shard counts, and shard failures, this commit changes all our extractor search requests to set `.setAllowPartialSearchResults(false)`.
- Scrolls are automatically cleared when a search failure occurs with `.setAllowPartialSearchResults(false)` set.
- Code error handling is simplified

Issue #55521 suggested that audit messages were not written when
closing an unassigned job. This is not the case, but we didn't
have a test to prove it.
Backport of #55571
The ML info endpoint returns the max_model_memory_limit setting
if one is configured. However, it is still possible to create
a job that cannot run anywhere in the current cluster because
no node in the cluster has enough memory to accommodate it.
This change adds an extra piece of information,
limits.effective_max_model_memory_limit, to the ML info
response that returns the biggest model memory limit that could
be run in the current cluster assuming no other jobs were
running.
The idea is that the ML UI will be able to warn users who try to
create jobs with higher model memory limits that their jobs will
not be able to start unless they add a bigger ML node to their
cluster.
Backport of #55529
Adds a "node" field to the response from the following endpoints:
1. Open anomaly detection job
2. Start datafeed
3. Start data frame analytics job
If the job or datafeed is assigned to a node immediately then
this field will return the ID of that node.
In the case where a job or datafeed is opened or started lazily
the node field will contain an empty string. Clients that want
to test whether a job or datafeed was opened or started lazily
can therefore check for this.
Backport of #55473
PEMUtils would incorrectly fill the encryption password with zeros
(the '\0' character) after decrypting a PKCS#8 key.
Since PEMUtils did not take ownership of this password it should not
zero it out because it does not know whether the caller will use that
password array again. This is actually what PEMKeyConfig does - it
uses the key encryption password as the password for the ephemeral
keystore that it creates in order to build a KeyManager.

In the test after the first load event is is not known which models are cached as

The models could have been loaded 1 or 2 times not exactly twice
This change folds the removal of the in-progress snapshot entry
into setting the safe repository generation. Outside of removing
an unnecessary cluster state update, this also has the advantage
of removing a somewhat inconsistent cluster state where the safe
repository generation points at `RepositoryData` that contains a
finished snapshot while it is still in-progress in the cluster
state, making it easier to reason about the state machine of
upcoming concurrent snapshot operations.
Today a read-only engine requires a complete history of operations, in the
sense that its local checkpoint must equal its maximum sequence number. This is
a valid check for read-only engines that were obtained by closing an index
since closing an index waits for all in-flight operations to complete. However
a snapshot may not have this property if it was taken while indexing was
ongoing, but that's ok.
This commit weakens the check for a complete history to exclude the case of a
searchable snapshot.

This change ensures that we return the latest expiration time
when retrieving the response from the index.
This commit also fixes a bug that stops the garbage collection of saved responses if the async search index is deleted.
