Some small clarifications about force-merging and global ordinals, particularly
that global ordinals are cheap on a single-segment index and how this relates
to frozen indices.
Fixes#41687
This commit renames the SLM package from snapshotlifecycle to slm. We
have all come to know index lifecycle management as ILM, the APIs and
settings use ilm, and it would be nice of the package did too. For SLM,
let's use slm for all of these including the package name from the
beginning.
We often start testing with early access versions of new Java
versions and this have caused minor issues in our tests
(i.e. #43141) because the version string that the JVM reports
cannot be parsed as it ends with the string -ea.
This commit changes how we parse and compare Java versions to
allow correct parsing and comparison of the output of java.version
system property that might include an additional alphanumeric
part after the version numbers
(see [JEP 223[(https://openjdk.java.net/jeps/223)). In short it
handles a version number part, like before, but additionally a
PRE part that matches ([a-zA-Z0-9]+).
It also changes a number of tests that would attempt to parse
java.specification.version in order to get the full version
of Java. java.specification.version only contains the major
version and is thus inappropriate when trying to compare against
a version that might contain a minor, patch or an early access
part. We know parse java.version that can be consistently
parsed.
Resolves#43141
In data frame transforms the same scheduler controls both
retries in the event of search failures and gaps between
checks for changes when the transform is running continuously.

This commit removes the method AllocationService.reroute(ClusterState, String, boolean)
in favor of AllocationService.reroute(ClusterState, String).
Motivations are:
there are already 3 other reroute methods in this class
this method is always called with the debug parameter set to false
almost all tests use the method reroute(ClusterState, String)
* As a result of #44665 the collections returned by the deserialization methods on `StreamInput` may be either mutable or immutable now,
this PR adds documentation for that fact
In 7.x we cannot start a new master-eligible node before the cluster has formed
since we first try and update minimum_master_nodes and this is blocked. This
commit changes the test to start a data-only node so that no such adjustment is
necessary.

Add more logging to indexRandom
Seems that asynchronous indexing from indexRandom sometimes indexes
the same document twice, which will mess up the expected score calculations.
For example, indexing:
{ "index" : {"_id" : "1" } }
{"important" :"phrase match", "less_important": "nothing important"}
{ "index" : {"_id" : "2" } }
{"important" :"nothing important", "less_important" :"phrase match"}
Produces the expected scores: 13.8 for doc1, and 1.38 for doc2
indexing:
{ "index" : {"_id" : "1" } }
{"important" :"phrase match", "less_important": "nothing important"}
{ "index" : {"_id" : "2" } }
{"important" :"nothing important", "less_important" :"phrase match"}
{ "index" : {"_id" : "3" } }
{"important" :"phrase match", "less_important": "nothing important"}
Produces scores: 9.4 for doc1, and 1.96 for doc2 which are found in the
error logs.

Fields in JSON logs should be an escaped JSON fields. It is a broken json value at the moment
"stats": "["group1", "group2"]", -> "stats": "[\"group1\", \"group2\"]",
This should later be refactored into a JSON array of strings (the same as types in 7.x)
Today we block access to the pending tasks API before the cluster has recovered
its state. There's no real need to do so, and the master does meaningful work
even before performing state recovery so it might sometimes be useful to allow
access to this API. This commit changes this API to ignore all cluster blocks.
Fixes#44652
Since #44344 we use IndicesOptions.LENIENT_EXPAND_OPEN
when deciding which indices to include in checkpoint
calculation. This change uses the same option when
deciding which indices to search for data and which
indices to get mappings from, otherwise there is a
potential mismatch between the checkpoint details and
what is searched elsewhere.
The field has to be defined in log4j2.properties and should be an
escaped JSON for now (it is a broken JSON at the moment). This should later be refactored into a JSON array
of strings.
Deprecation logger was filtering log entries by key, that means that if two log messages with the same key are logged from different users, then the second log messages will be filtered.
This change allows to log deprecation message with the same key by different users.

backport #44587
* It seems redundant to synchronize here and check that the map hasn't checked via the `isRunning` under the mutex
* The map won't change if under the mutex that locks on all the updates to it
* Without the mutex it's very unlikely to change inside the method call relative to the likelihood of changing until the generic pool where we check for `isRunning` again anyway
-> just remove the synchronization (it's on the IO loop) and check since we do check the running state on the generic pool under the mutex anyway when we actually fail it
We have to copy the field names otherwise we either have a handle of a
list that a caller might mutate or we might mutate when they aren't
expecting it, or worse, a handle of a list that is not mutable (and we
end up mutating the list).

These Azure tests have hard println statements which means we always see
these messages during configuration. Yet, there are unnecessary most of
the time. This commit changes them to use debug logging.
* We only had the `size == 0` optimization in some but not all spots of deserializing collections in this class, fixed the remaining spots.
* Also fixed the a similar spot when deserializing `ThreadContextStruct` that could now be simplified (it was apparently doing it's own version of this optimization for the first map it deserialized before ... but not for the second map -> made it not instantiate anything if both maps are empty since it's always the same object here anyway)
* Optimize some StreamOutput Operations
* Writing numbers byte by byte adds a lot of unnecessary bounds checks to serialization
* Serializing to a threadlocal `byte[]` instead and bulk writing gives about a 50% speedup on `long` and `vlong` (for large numbers) writes and 30% for `int`, `vint` on Linux on an i9
* Using a threadlocal of the maximum string buffer size we used to allocate before also removes allocations when writing strings in general since we now never have to allocate a `byte[]` for that
* And don't have to GC one either resolving the TODO removed here
In https://github.com/elastic/elasticsearch/pull/41913 setting up the
temp dir for ES was moved from the env script to individual cli scripts.
However, moving it to the windows service cli was missed. This commit
restores setting up the temp dir for the windows service control script.
Today when checksumming a plugin zip during plugin install, we read all
of the bytes of the zip into memory at once. When trying to run the
plugin installer on a small heap (say, 64 MiB), this can lead to the
plugin installer running out of memory when checksumming large
plugins. This commit addresses this by reading the plugin bytes in 8 KiB
chunks, thus using a constant amount of memory independent of the size
of the plugin.
This commit converts all remaining TransportRequest and
TransportResponse classes to implement Writeable, and disallows
Streamable implementations.

This commit adds some default CLI JVM options to control the heap size
and the garbage collector used for the CLI tools. We do this because
otherwise the JVM will default to large initial and max heap sizes based
on the RAM visible to the JVM (which could be all the physical RAM on
the machine if not run in a container-aware JVM). This commit therefore
sets the initial heap size to 4m, the max heap size to 64m, the garbage
collector to the serial collector, and leaves this user-configurable by
honoring ES_JAVA_OPTS last.
This adds a new dynamic cluster setting `xpack.data_frame.num_transform_failure_retries`.
This setting indicates how many times non-critical failures should be retried before a data frame transform is marked as failed and should stop executing. At the time of this commit; Min: 0, Max: 100, Default: 10
Several files in the REST APIs nav section are included using
:leveloffset: tags. This increments headings (h2 -> h3, h3 -> h4, etc.)
in those files and removes the :leveloffset: tags.
Other supporting changes:
* Alphabetizes top-level REST API nav items.
* Change 'indices APIs' heading to 'index APIs.'
* Changes 'Snapshot lifecycle management' heading to sentence case.
* We shouldn't just swallow the interrupt here quietly and keep going on the IO thread
* Currently interrupt continues here just the same way an invocation of `acceptIncomingRequests` woudl have made things continue

NamedAnalyzer should return the same AnalysisMode than any custom analyzer it
wraps, otherwise AnalysisMode.ALL. This used to be only CustomAnalyzer in the
past, but with the introduction of the ReloadableCustomAnalyzer this needs to be
added as an option where the analysis mode gets propagated.

elastic/elasticsearch#41281 added custom metadata parameter to
snapshots. During review, the parameter name was changed from '_meta' to
'metadata,' but the documentation wasn't updated. This corrects the
documentation to use the 'metadata' name.
