This commit adjusts randomization for the cluster shard limit tests so
that there is often more of a gap left between the limit and the size of
the first index. This allows the same randomization to be used for all
tests, and alleviates flakiness in
`testIndexCreationOverLimitFromTemplate`.
Today the comment boldly claims that this line of code keeps nodes above the
10-byte low watermark when in fact this is not true at all. This change fixes
this so that it really does keep nodes above the low watermark.
Fixes#45338. Again.
This is a preliminary of #46250 making the snapshot
delete work by doing all the metadata updates first
and then bulk deleting all of the now unreferenced
blobs.
Before this change, the metadata updates for each shard
and subsequent deletion of the blobs that have become unreferenced
due to the delete would happen sequentially shard-by-shard
parallelising only over all the indices in the snapshot.
This change makes it so the all the metadata updates
happen in parallel on a shard level first.
Once all of the updates of shard-level metadata have finished,
all the now unreferenced blobs are deleted in bulk.
This has two benefits (outside of making #46250 a smaller change):
* We have a lower likelihood of failing to update shard level metadata because
it happens with priority and a higher degree of parallelism
* Deleting of unreferenced data in the shards should go much faster in many cases (rolling indices, large number of indices with many unchanged shards) as well because a number of small bulk deletions (just two blobs for `index-N` and `snap-` for each unchanged shard) are grouped into larger bulk deletes of `100-1000` blobs depending on Cloud provider (even though the final bulk deletes are happening sequentially this should be much faster in almost all cases as you'd parallelism of 50 (GCS) to 500 (S3) snapshot threads to achieve the same delete rates when deleting from unchanged shards).
Due to a regression bug the metadata Active Directory realm
setting is ignored (it works correctly for the LDAP realm type).
This commit redresses it.
Closes#45848
DATE_PART(<datetime unit>, <date/datetime>) is a function that allows
the user to extract the specified unit from a date/datetime field
similar to the EXTRACT (<datetime unit> FROM <date/datetime>) but
with different names and aliases for the units and it also provides more
options like `DATE_PART('tzoffset', datetimeField)`.
Implemented following the SQL server's spec: https://docs.microsoft.com/en-us/sql/t-sql/functions/datepart-transact-sql?view=sql-server-2017
with the difference that the <datetime unit> argument is either a
literal single quoted string or gets a value from a table field, whereas
in SQL server keywords are used (unquoted identifiers) and it's not
possible to use a value coming for a table column.

We cancel ongoing peer recoveries if a node joins the cluster with a completely
up-to-date copy of a shard, because we can use such a copy to recover a replica
instantly. However, today we only look for recoveries to cancel while there are
unassigned shards in the cluster. This means that we do not contemplate the
cancellation of the last few recoveries since recovering shards are not
unassigned. It might take much longer for these recoveries to complete than
would be necessary if they were cancelled.
This commit fixes this by checking for cancellable recoveries even if all
shards are assigned.
Fixes multiple Active Directory related tests that run against the
samba fixture. Some were failing since we changed the realm settings
format in 7.0 and a few were slightly broken in other ways.
We can move to cleanup the tests in a follow up but this work fits
better to be done with or after we move the tests from a Samba
based fixture to a real(-ish) Microsoft Active Directory based
fixture.

This commit change the repositories base paths used in Azure/S3/GCS

- Build paths with PathUtils#get instead of hard-coding a string with
forward slashes.
- Do not try to match the whole message that includes paths. The
file separator is `\\` in windows but when we throw an Elasticsearch
Exception, the message is formatted with LoggerMessageFormat#format
which replaces `\\` with `\` in Path names. That means that in Windows
the Exception message will contain paths with single backslashes while
the expected string that comes from Path#toString on filename and
env.configFile will contain double backslashes. There is no point in
attempting to match the whole message string for the purpose of this test.

The test of constantTimeEquals could get unlucky and randomly produce
the same two strings. This commit tweaks the test to ensure the two
string are unique, and the loop inside constantTimeEquals is actually
executed (which requires the strings be of the same length).

As a result of #45689 snapshot finalization started to
take significantly longer than before. This may be a
little unfortunate since it increases the likelihood
of failing to finalize after having written out all
the segment blobs.
This change parallelizes all the metadata writes that
can safely run in parallel in the finalization step to
speed the finalization step up again. Also, this will
generally speed up the snapshot process overall in case
of large number of indices.
This is also a nice to have for #46250 since we add yet
another step (deleting of old index- blobs in the shards
to the finalization.
When an integration test fails before the assertion of the results it's
missing information, like the file name and the line in the file where
the test resides.

The method Setting#getRaw leaks implementation details about settings,
namely that they are backed by strings. We do not want code to rely upon
this, so this commit makes Setting#getRaw private as a first step
towards hiding the implementaton details of settings from the rest of
the codebase.
This moves the way Painless maintains function headers for use
across compilation into its own class - FunctionTable. This
allows us to store a dedicated object for function lookup at
runtime for the def type instead of a loose Map of functions.
Today plugins may provide upgraders for custom metadata and index metadata, but
these upgraders are bypassed during a rolling restart. Fortunately this
extension mechanism is unused by all known plugins. This commit removes these
extension points.

With this change the test setup for ML config upgrade
tests only waits for v6.6+ ML index templates to be
installed if the old cluster is running version 6.6.0
or higher.
Previously it was always waiting, but timing out without
failing the test if the templates were not installed
within 10 seconds, effectively just adding a pointless
10 second sleep to BWC tests against versions earlier
than 6.6.0. This problem was exposed by #47112.
Fixes#47286
Today if you create an index in a cluster without any data nodes then it will
report yellow health because it never attempts to assign any shards if there
are no data nodes, so the new shards remain at `AllocationStatus.NO_ATTEMPT`.
This commit moves the new primaries to `AllocationStatus.DECIDERS_NO` in this
situation, causing the cluster health to move to red.
Fixes#41073

A refactoring in 6.6 meant that the ML daily
maintenance actions have not been run at all
since then. This change installs the local
master listener that schedules the ML daily
maintenance, and also defends against some
subtle race conditions that could occur in the
future if a node flipped very quickly between
master and non-master.
Fixes#47003
Fixes a bug related to how "closed replicated indices" (introduced in 7.2) interact with the index
metadata storage mechanism, which has special handling for closed indices (but incorrectly
handles replicated closed indices). On non-master-eligible data nodes, it's possible for the
node's manifest file (which tracks the relevant metadata state that the node should persist) to
become out of sync with what's actually stored on disk, leading to an inconsistency that is then
detected at startup, refusing for the node to start up.
Closes#47276
Currently DateMathParser with roundUp = true is relying on the DateFormatter build with
combined optional sub parsers with defaulted fields (depending on the formatter).
That means that for yyyy-MM-dd'T'HH:mm:ss||yyyy-MM-dd'T'HH:mm:ss.SSS
Java.time implementation expects optional parsers in order from most specific to
least specific (reverse in the example above).
It is causing a problem because the first parsing succeeds but does not consume the full input.
The second parser should be used.
We can work around this with keeping a list of RoundUpParsers and iterate over them choosing
the one that parsed full input. The same approach we used for regular (non date math) in
relates #40100

This commit removes a use of Setting#getRaw from the deprecation header
tests. The use of Setting#getRaw is not needed here, the x-content
infrastructure will take care of emitting the appropriate values here,
and so the caller does not need to convert these to string
representations of the settings values.
These settings were using get raw to fallback to whether or not SSL is
enabled. Yet, we have a formal mechanism for falling back to a
setting. This commit cuts over to that formal mechanism.
