This change adds "contains" method to LocalCheckpointTracker.
One of the use cases is to check if a given operation has been processed
in an engine or not by looking up its seq_no in LocalCheckpointTracker.

In cases when mixed secure S3 client credentials and insecure S3 client
credentials were used (that is, those defined on the repository), we
were overriding the credentials from the repository using insecure
settings to all the repositories. This commit fixes this by not mixing
up repositories that use insecure settings with those that use secure
settings.
Changes the default of the `node.name` setting to the hostname of the
machine on which Elasticsearch is running. Previously it was the first 8
characters of the node id. This had the advantage of producing a unique
name even when the node name isn't configured but the disadvantage of
being unrecognizable and not being available until fairly late in the
startup process. Of particular interest is that it isn't available until
after logging is configured. This forces us to use a volatile read
whenever we add the node name to the log.
Using the hostname is available immediately on startup and is generally
recognizable but has the disadvantage of not being unique when run on
machines that don't set their hostname or when multiple elasticsearch
processes are run on the same host. I believe that, taken together, it
is better to default to the hostname.
1. Running multiple copies of Elasticsearch on the same node is a fairly
advanced feature. We do it all the as part of the elasticsearch build
for testing but we make sure to set the node name then.
2. That the node.name defaults to some flavor of "localhost" on an
unconfigured box feels like it isn't going to come up too much in
production. I expect most production deployments to at least set the
hostname.
As a bonus, production deployments need no longer set the node name in
most cases. At least in my experience most folks set it to the hostname
anyway.
With the upcoming instance bindings, the singular *Binding name isn't descriptive enough
with multiple binding types. This renames the existing *Binding classes to *ClassBinding.
Mechanical change (with some error messages changed from binding to class binding by
hand).
By moving CompletionStats into the engine we can easily cache the stats for
read-only engines if necessary. It also moves the responsibiltiy out of IndexShard
which has quiet some complexity already.

Today if we fetch common stats from a shard we might get a partial response
if the shard is closed while we fetch the stats. This causes hard to track and
reproduce NPEs. This change streamlines null checking to ensure we only render
stats we actually received.
Wraps all lines in our test framework at 140 characters because that is
our standard line length and removes all of the checkstyle suppressions
for the test framework.
Drops most of `ModuleTestCase` because it isn't used and we're moving
away from using guice in the way that it wants to test anyway. Also
switches a few classes that extend it but don't use it to extend
`ESTestCase` instead.
We currently special-case SynonymFilterFactory and SynonymGraphFilterFactory, which need to
know their predecessors in the analysis chain in order to correctly analyze their synonym lists. This
special-casing doesn't work with Referring filter factories, such as the Multiplexer or Conditional
filters. We also have a number of filters (eg the Multiplexer) that will break synonyms when they
appear before them in a chain, because they produce multiple tokens at the same position.
This commit adds two methods to the TokenFilterFactory interface.
* `getChainAwareTokenFilterFactory()` allows a filter factory to rewrite itself against its preceding
filter chain, or to resolve references to other filters. It replaces `ReferringFilterFactory` and
`CustomAnalyzerProvider.checkAndApplySynonymFilter`, and by default returns `this`.
* `getSynonymFilter()` defines whether or not a filter should be applied when building a synonym
list `Analyzer`. By default it returns `true`.
Fixes#33609
This test occasionally fails in `testCollectSearchShards` waiting on what seems
to be a search request to a remote cluster for one second. Given that the test
fails here very rarely I suspect maybe one second is very rarely not enough so
we could fix it by increasing the max wait time slightly.
Closes#33852
By moving DocStats into the engine we can easily cache the stats for
read-only engines if necessary. It also moves the responsibility out of IndexShard
which has quiet some complexity already.
The documentation currently tells users to use `doc['event_date'].value.getMillis` to access
milliseconds in a date. It turns out the way it works is `doc['event_date'].value.millis`. This
change corrects this and gives a hint at how other date related methods work.
The fix in #33757 introduces some workaround since FilterCodecReader didn't
support unwrapping. This cuts over to a more elegant fix to access the readers
segment infos.
Previously multiple comma separated lists of options where not
recognized correctly which resulted in only the last of them
to be taked into account, e.g.:
For the following query:
SELECT * FROM test WHERE QUERY('search', 'default_field=foo', 'default_operator=and')"
only the `default_operator=and` was finally passed to the ES query.
Fixes: #32602
It is not obvious that a filesystem-level backup may capture an inconsistent
set of files that may fail on restore, or (worse) succeed having silently
discarded some data. This change spells the out, and reorganises the first page
or so of the snapshot/restore docs to make this warning fit more nicely.
This commit changes the random_score function to use the global docID of the document
rather than the segment docID to generate random scores. As a result documents that have
the same segment docID within the shard will generate different scores.
Add minimal sanity checks to custom/scripted similarities.
Lucene 8 introduced more constraints on similarities, in particular:
- scores must not be negative,
- scores must not decrease when term freq increases,
- scores must not increase when norm (interpreted as an unsigned long)
increases.
We can't check every single case, but could at least run some sanity checks.

* Profiler: Don’t profile NEXTDOC for ConstantScoreQuery.
A ConstantScore query will return the iterator of its inner query.
However, when profiling, the constant score query is wrapped separately
from its inner query, which distorts the times emitted by the profiler.
Return the iterator directly in such a case.
Closes#23430
Instead of having one constructor that accepts all arguments, all parameters
should be provided via setters. Only leader and follower index are required
arguments. This makes using this class in tests and transport client easier.
DAYNAME and MONTHNAME functions tests will be skipped if the right JVM parameter (-Djava.locale.providers=COMPAT) is not used in unit testing environment
* TESTS: Set SO_LINGER = 0 for MockNioTransport
* Prevents lingering sockets in TIME_WAIT piling up during test runs and leading to port collisions that manifest as timeouts
* Fixes#32552
Gradle can sometimes emit mixed log lines due to how we spawn things in
separate processes. This commit changes the jarhell integ test to only
look for the exception and message, instead of including the outer part
about the exception in thread main.

The change in #27500 introduces this regression that causes `_get` and `_term_vector`
actions to run on the network thread if the realtime flag is set.
This fixes the issue by delegating to the super method forking on the corresponding threadpool.
We use similar / same concepts in SerachTransportService and HandledTransportAction but both
duplicate the efforts with slightly different implementation details. This streamlines
sending responses / exceptions back to a channel in an ActionListener with appropriate logging.
Make sure that all java files have a package declaration and that all of
the package declarations line up with the directory structure. This
would have caught the bug that I caused in
190ea9a6def9082348d983b16420ef02607d4c17 and fixed in
b6d68bd805f1858a0210e381402236dea1d42509.
The original statement "Runs a match_phrase query on each field and combines the _score from each field." for the phrase type is a but misleading. The phrase type behaves like the best_fields type and does not combine the scores of each fields.
In #33241 we moved the file-based discovery functionality to core
Elasticsearch, but preserved the `discovery-file` plugin, and support for the
existing location of the `unicast_hosts.txt` file, for BWC reasons. This commit
completes the removal of this plugin.
