We currently check whether translog files can be trimmed whenever we create a new translog generation or close a view. However #25294 added a long translog retention period (12h, max 512MB by default), which means translog files should potentially be cleaned up long after there isn't any indexing activity to trigger flushes/the creation of new translog files. We therefore need a scheduled background check to clean up those files once they are no longer needed.

This commit does two things:
- bumps the version from 6.0.0-alpha3 to 6.0.0-beta1
- renames the 6.0.0-alpha3 version constant to 6.0.0-beta1

This commit adjusts the expectation for the max number of threads in the
scaling thread pool configuration test. The reason that this expectation
is incorrect is because we removed the limitation that the number of
processors maxes out at 32, instead letting it be the true number of
logical processors on the machine. However, when we removed this
limitation, this test was never adjusted to reflect the new reality yet
it never arose since our tests were not running on machines with
incredibly high core counts.

Updating the global checkpoint on a replica can occur for a few
different reasons:
- from inlined global checkpoint updates
- from a primary term transition
- from finalizing recovery
Yet, the trace logging for a global checkpoint update does not present
this information that can be useful when tracing test failures. This
commit adds a reason for the global checkpoint update on a replica so
that we can trace these updates.

This commit enables the console appender for the settings deprecation
logger used in the deprecated settings logging test. This output will be
useful if this test fails again (it failed once mysteriously).
The current BWC code in `BulkItemRequest` mutates the underlying `DocWriteRequests` which causes test failures and unexpected state (our test infra checks bwc serialization on the fly). This PR removes this logic from master. Another PR will add a BWC layer to 5.x only.
This PR contains the logic in https://github.com/elastic/elasticsearch/pull/25510 , which is needed to run the tests.
Previously the primary didn't update it's own local checkpoint (and thus the global checkpoint) before some indexing occurred. With recent changes the primary now properly initializes it self and thus ops recovery is possible even if no indexing has occurred.
This commit adds cross-settings validation for the low/high/flood stage
disk watermark settings. This validation was enabled by the introduction
of multiple settings validation.

When a shard is promoted to replica, it's possible that it was
previously a replica that started following a new primary. When it
started following this new primary, the state of its local checkpoint
tracker was reset. Upon promotion, it's possible that the state of the
local checkpoint tracker has not yet restored from a successful
primary-replica re-sync. To account for this, we must restore the state
of the local checkpoint tracker when a replica shard is promoted to
primary. To do this, we stream the operations in the translog, marking
the operations that are in the translog as completed. We do this before
we fill the gaps on the newly promoted primary, ensuring that we have a
primary shard with a complete history up to the largest maximum sequence
number it has ever seen.

This commit refactors the global checkpont tracker to make it more
resilient. The main idea is to make it more explicit what state is
actually captured and how that state is updated through
replication/cluster state updates etc. It also fixes the issue where the
local checkpoint information is not being updated when a shard becomes
primary. The primary relocation handoff becomes very simple too, we can
just verbatim copy over the internal state.

The created and found fields in index and delete responses became obsolete after the introduction of the result field in index, update and delete responses (#19566).
After deprecating the created and found fields in 5.x (#19633), now they are removed.

Moved SocketAccess.doPrivileged up the stack to DefaultS3OutputStream in repository-S3 plugin to avoid SecurityException by Streams.copy(). A plugin is only allowed to use its own jars when performing privileged operations. The S3 client might open a new Socket on close(). #25192
Indexing ids in binary form should help with indexing speed since we would
have to compare fewer bytes upon sorting, should help with memory usage of
the live version map since keys will be shorter, and might help with disk
usage depending on how efficient the terms dictionary is at compressing
terms.
Since we can only expect base64 ids in the auto-generated case, this PR tries
to use an encoding that makes the binary id equal to the base64-decoded id in
the majority of cases (253 out of 256). It also specializes numeric ids, since
this seems to be common when content that is stored in Elasticsearch comes
from another database that uses eg. auto-increment ids.
Another option could be to require base64 ids all the time. It would make things
simpler but I'm not sure users would welcome this requirement.
This PR should bring some benefits, but I expect it to be mostly useful when
coupled with something like #24615.

This is a regression introduced in #25510, which removed the explicit fetching of upstream. Sadly this doesn't work if you don't have any local branch referring to `upstream` as an upstream branch.
In the past global checkpoint syncing was done in the background based an interval set by an index setting. In order to set that setting something reasonable for a test, the master needed to know about the setting. Therefore the test didn't check global checkpoints if the master was old. These days the global checkpoint sync is inlined with indexing operations and that restriction is not needed.
Some times we need a fix / change to have two parts in two different branches (corresponding to two different ES releases). In order to be able to test these cases you need to run the BWC tests against a local branch rather than then using a branch from `github.com/elastic/elasticsearch`.
This commit adds a system property called `tests.bwc.refspec` that allows you to do it. Note that I've chosen to go with the simplest code change for now, at the expense of some user friendliness.
Adds a unit test that checks the TermSuggestionContext contents that is the result
of TermSuggestionBuilder#build vs. the values the original builder contains.
Transport profiles unfortunately have never been validated. Yet, it's very
easy to make a mistake when configuring profiles which will most likely stay
undetected since we don't validate the settings but allow almost everything
based on the wildcard in `transport.profiles.*`. This change removes the
settings subset based parsing of profiles but rather uses concrete affix settings
for the profiles which makes it easier to fall back to higher level settings since
the fallback settings are present when the profile setting is parsed. Previously, it was
unclear in the code which setting is used ie. if the profiles settings (with removed
prefixes) or the global node setting. There is no distinction anymore since we don't pull
prefix based settings.
In the rolling upgrade tests, there is a test to create an index with
replica shards and ensure that in the mixed cluster environment, the
cluster health is green before any other tests are executed. However,
there were two problems with this. First, if the replica shard was
residing on the restarted node, then delayed allocation will kick in and
cause the cluster health request to timeout after 1m. The fix to this
was to drastically lower the delayed allocation setting. Second, if the
primary exists on the higher version node, then the replica cannot be
assigned to the lower version node because recovery cannot happen from
lower lucene versions. The fix here was to wait for the cluster health
to be yellow instead of green in the mixed cluster environment. In the
fully upgraded cluster, the cluster health check waits for a green
cluster as before.
Closes#25185
This change adds validation to the RemoteClusterConnection to ensure
we always use seed nodes from the same cluster. While we still allow to use
an arbitrary cluster alias we ensure that we, once we connected to a cluster the first time,
we always check against that initial cluster name when we execute a seed node handshake.
sequence number data in Lucene commit points. Instead, the test
retrieves the _seq_no value from the commit point directly and converts
it to a Long value.
This change adds a basic unit test for the SuggestionSearchContext that is
created as output of SuggestionBuilder#build. The current test only adds checks
for the common fields (like text, prefix, fieldName etc...).

We previously grouped all the license and notice files for httpcore, httpcore-nio, httpclient and httpasyncclient under the same license and notice file. There were though subtle differences between those which we didn't keep track of. For instance the httpcore license file has slightly changed since 4.4 which we have missed to track.
This commit goes back to having one license and notice file for each jar, to be completely sure that each dependency is associated with exactly the right licene and notice file.
Closes#25567
