Improve failure handling of retryable errors by retrying remote calls in
a exponential backoff like manner. The delay between a retry would not be
longer than the configured max retry delay. Also retryable errors will be
retried indefinitely.

This change clarifies the documentation of the context completion suggester
regarding filtering and boosting with contexts.
Unlike the suggester v1, filtering on multiple contexts
works as a disjunction, a suggestion matches if it contains at least one of the provided
context values and boosting selects the maximum score among the matching contexts.
This commit also adapts an old test that was written for the v1 suggester and commented out
for version 2 because the behavior changed.
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.
This commit adds settings upgraders for the search.remote.* settings
that can be in the cluster state to automatically upgrade these settings
to cluster.remote.*. Because of the infrastructure that we have here,
these settings can be upgraded when recovering the cluster state, but
also when a user tries to make a dynamic update for these settings.
This commit adds test coverage for two cases not previously covered by
the existing testing. Namely, we add coverage ensuring that the executor
is used to notify listeners being added that are immediately notified
because the shard is closed or because the global checkpoint is already
beyond what the listener knows.
When a replica starts following a newly promoted primary, it may have
some operations which don't exist on the new primary. Thus we need to
throw those operations to align a replica with the new primary. This can
be done by first resetting an engine from the safe commit, then replaying
the local translog up to the global checkpoint.

These logs are incredibly verbose, and it makes chasing normal failures
burdensome. This commit removes the debug logging, which can be
reenabled again if needed.
* SQL: Make Literal a NamedExpression
Literal now is a NamedExpression reducing the need for Aliases for
folded expressions leading to simpler optimization rules.
Fix#33523
* Improves doc values format deprecation message
This changes the deprecation message when doc values fields do not
supply a format form logging a deprecation warning for each offending
field individually to logging a single message which lists all
offending fields
Closes#33572
* Updates YAML test with new deprecation message
Also adds a test to ensure multiple deprecation warnings are collated
into one message
* Condenses collection of fields without format check
Moves the collection of fields that don't have a format to a separate
loop and moves the logging of the deprecation warning to be next to it
at the expesnse of looping through the field list twice
* fixes typo
* Fixes test
Today the full cluster restart tests do not preserve cluster settings on
restart. This is a mistake because it is not an accurate reflection of
reality, we do not expect users to clear cluster settings when they
perform a full cluster restart. This commit makes it so that all full
cluster restart tests preserve settings on upgrade.
Currently we keep track of how many bytes are currently being written to disk
in an AtomicLong within InternalEngine, updating it on refresh. The IndexWriter
has its own accounting for this, and exposes it via a getFlushingBytes method
in the latest lucene 8 snapshot. This commit removes the InternalEngine tracking
in favour of just using the IndexWriter method.
Upgrading list settings is broken because of the conversion that we do
to strings, and then when we try to put back the upgraded value we do
not know that it is a representation of a list. This commit addresses
this by adding special handling for list settings.
This change adds an engine implementation that opens a reader on an
existing index but doesn't permit any refreshes or modifications
to the index.

This allows users to filter out tokens from a TokenStream using painless scripts,
instead of having to write specialised Java code and packaging it up into a plugin.
The commit also refactors the AnalysisPredicateScript.Token class so that it wraps
and makes read-only an AttributeSource.
This change tightens up the meaning of the "input_fields" field
in the file structure finder output. Previously it was permitted
but not calculated for JSON and XML files. Following this change
the field is called "column_names" and is only permitted for
delimited files.
Additionally the way the column names are set for headerless
delimited files is refactored to encapsulate the way they're
named to one line of the code rather than having the same
logic in two places.
When we see a settings value, it could be a list. Yet this should only
happen if the underlying setting type is a list setting type. This
commit adds validation that when we get a setting value that is a list,
that the setting that we are getting is a list setting. And similarly,
if we get a value for a list setting, the underlying value should be a
list.
This change copies and validates the soft-deletes setting during resize.
If the source enables soft-deletes, the target must also enable it.
Closes#33321
I created a test a few days ago and declared a package that doesn't line
up with the directory structure. Oops. I a little surprised nothing
complained. But this fixes it.
Previously, when an arithmetic function got applied on a
table column in the `SELECT` clause, the name of the result
column contained weird characters used internally when
processing the SQL statement e.g.:
SELECT CHAR(emp_no % 10000) FROM "test_emp"
returned:
CHAR((emp_no{f}#14) % 10000))
as the column name instead of:
CHAR((emp_no) % 10000))
Also, fix an issue that causes a ClassCastException to be thrown
when using functions where both arguments are literals.

* LeafCollector.setScorer() now takes a Scorable
* Scorers may not have null Weights
* IndexWriter.getFlushingBytes() reports how much memory is being used by IW threads writing to disk
In some cases we want to skip wiping cluster settings after a REST
test. For example, one use-case would be in the full cluster restart
tests where want to test cluster settings before and after a full
cluster restart. If we wipe the cluster settings before the restart,
then it would not be possible to assert on them after the restart.
* [CCR] Delay auto follow license check
so that we're sure that there are auto follow patterns configured
Otherwise we log a warning in case someone is running with basic or gold
license and has not used the ccr feature.
This is a new index privilege that the user needs to have in the follow cluster.
This privilege is required in addition to the `manage_ccr` cluster privilege in
order to execute the create and follow api.
Closes#33555
Today the FilterRoutingTests take the belt-and-braces approach of excluding
some node attribute values and including some others. This means that we don't
really test that both inclusion and exclusion work correctly: as long as one of
them works as expected then the test will pass. This change improves these
tests by only using one approach at once, demonstrating that both do indeed
work, and adds tests for various other scenarios too.
* Correctly handle NONE keyword for system keystore
As defined in the PKCS#11 reference guide
https://docs.oracle.com/javase/8/docs/technotes/guides/security/p11guide.html
PKCS#11 tokens can be used as the JSSE keystore and truststore and
the way to indicate this is to set `javax.net.ssl.keyStore` and
`javax.net.ssl.trustStore` to `NONE` (case sensitive).
This commits ensures that we honor this convention and do not
attempt to load the keystore or truststore if the system property is
set to NONE.
* Handle password protected system truststore
When a PKCS#11 token is used as the system truststore, we need to
pass a password when loading it, even if only for reading
certificate entries. This commit ensures that if
`javax.net.ssl.trustStoreType` is set to `PKCS#11` (as it would
when a PKCS#11 token is in use) the password specified in
`javax.net.ssl.trustStorePassword` is passed when attempting to
load the truststore.

In some cases we want to deprecate a setting, and then automatically
upgrade uses of that setting to a replacement setting. This commit adds
infrastructure for this so that we can upgrade settings when recovering
the cluster state, as well as when such settings are dynamically applied
on cluster update settings requests. This commit only focuses on cluster
settings, index settings can build on this infrastructure in a
follow-up.
When requesting job stats for `_all`, all ES tasks are accepted
resulting to loads of cluster traffic and a memory overhead.
This commit correctly filters out non ML job tasks.
Closes#33515
We may use different global checkpoints to validate/normalize the range
of a change request if the global checkpoint is advanced between these
calls. If this is the case, then we generate an invalid request range.
