Prior to this PR, there is a bug in ILM which does not allow ILM to stop
if one or more indices have an index.lifecycle.name which refers to
a policy that does not exist - the operation_mode will be stuck as
STOPPING until either the policy is created or the nonexistent
policy is removed from those indices.
This change allows ILM to stop in this case and makes the logging more
clear as to why ILM is not stopping.
This commit fixes a problem with BWC that was brought up in #40511. A
newer version of the code was emitting a new value for an enum to an
older version, and the older version could not handle that. It caused
the response to error. The MainResponse is now relaxed, and will accept
whatever values the server expose, and holds most of them as Strings
instead of complex objects.
Fixes#40511
We generate two pages with "funny" names:
* _changing_the_client_8217_s_initialization_code.html
* _changing_the_application_8217_s_code.html
The leading `_` comes from us not specifying the name of the page. The
`8217` comes about because of the single quote character. This is a
funny name, but it is the name that we have so we shouldn't change it
without putting in a redirect.
We're looking at switching these docs from being built with the
no-longer-maintained AsciiDoc project to being built with the
actively-maintained Asciidoctor project. Asciidoctor Doesn't include the
`8217`s in the generated ids. That is *better*, but we don't really want
to change the pages. Ultimately we'd prefer none of our pages start with
`_`, but that is a problem for a different time.
Anyway, this pins the ids to their "funny" id so it won't change when we
switch to Asciidoctor. We'll remove it later, when we have more fine
control of our redirects.
Drops the inline callouts from the painless reference book. These
callouts are incompatible with Asciidoctor and we'd very much like to
switch to Asciidoctor for building this book, partially because
Asciidoctor is actively developed and AsciiDoc is not, and partially
because it builds the book three times faster.
This change rejects an illegal combination of flush parameters where
force is true, but wait_if_ongoing is false. This combination is trappy
and should be forbidden.
Closes#36342
If there's an ongoing flush triggered by the translog flush threshold,
we may fail to execute a flush because waitIfOngoing is false by
default.

If a refresh, which is scheduled by the setting change, executes after
the index-2 operation and win the refresh race (i.e., maybeRefresh) with
the scheduledRefresh that we are going to check, then the latter will
return false.

By default, in integ tests we wait for the standalone cluster to start
by using the ant Get task to retrieve the cluster health endpoint.
However the ant task has no facilities for customising the trusted
CAs for a https resource, so if the integ test cluster has TLS enabled
on the http interface (using a custom CA) we need a separate utility
for that purpose.

This change adds information about which UI path
(if any) created ML anomaly detector jobs to the
stats returned by the _xpack/usage endpoint.
Counts for the following possibilities are expected:
* ml_module_apache_access
* ml_module_apm_transaction
* ml_module_auditbeat_process_docker
* ml_module_auditbeat_process_hosts
* ml_module_nginx_access
* ml_module_sample
* multi_metric_wizard
* population_wizard
* single_metric_wizard
* unknown
The "unknown" count is for jobs that do not have a
created_by setting in their custom_settings.
Closes#38403
- Added square brackets for the optional argument of precision

A user reported that the same query that takes ~900ms when querying an index
pattern only takes ~50ms when only querying indices that have matches. The
query is a date range query and we confirmed that the `can_match` phase works
as expected. I was able to reproduce this issue locally with a single node: with
900 1-shard indices, a query to an index pattern that matches all indices runs
in ~90ms while a query to the only index that has matches runs in 0-1ms.
This ended up not being related to the `can_match` phase but to the cost of
resolving aliases when querying an index pattern that matches lots of indices.
In that case, we first resolve the index pattern to a list of concrete indices
and then for each concrete index, we check whether it was matched through an
alias, meaning we might have to apply alias filters. Unfortunately this second
per-index operation runs in linear time with the number of matched concrete
indices, which means that alias resolution runs in O(num_indices^2) overall.
So queries get exponentially slower as an index pattern matches more indices.
I reorganized alias resolution into a one-step operation that runs in linear
time with the number of matches indices, and then a per-index operation that
runs in linear time with the number of aliases of this index. This makes alias
resolution run is O(num_indices * num_aliases_per_index) overall instead. When
testing the scenario described above, the `took` went down from ~90ms to ~10ms.
It is still more than the 0-1ms latency that one gets when only querying the
single index that has data, but still much better than what we had before.
Closes#40248
The xlint exclusions of the following plugins were removed:
* ingest-attachment.
* mapper-size.
* transport-nio. Removing the -try exclusion required some work, because
the NettyAdaptor implements AutoCloseable and NettyAdaptor#close() method
could throw an InterruptedException (ChannelFuture#await() and a generic
Exception is re-thrown, which maybe an ChannelFuture). The easiest way
around this to me seemed that NettyAdaptor should not implement AutoCloseable,
because it is not directly used in a try-with-resources statement.

It is possible to have SSL enabled but security disabled if security
was dynamically disabled by the license type (e.g. trial license).
e.g. In the following configuration:
xpack.license.self_generated.type: trial
# xpack.security not set, default to disabled on trial
xpack.security.transport.ssl.enabled: true
The security feature will be reported as
available: true
enabled: false
And in this case, SSL will be active even though security is not
enabled.
This commit causes the X-Pack feature usage to report the state of the
"ssl" features unless security was explicitly disabled in the
settings.

If a field `field_name` was missing in a document,
doc['field_name'].get(0) incorrectly retrieved
a value of the previously accessed document.
This happened because `get(int index)` function
was just accessing `values[index]` without
checking the number of values - `count`.
This PR fixes this.
There were some test failures caused by the background retention lease sync running on a relocated
primary. This commit fixes the situation that triggered the assertion and reactivates the failing test.

The Eclipse compiler (4.10, Photon) cannot build this test because it cannot
correctly infer the type arguments of the functions. Explicitely adding them
helps in this case.
TimeProcessor didn't implement `getWriteableName()` so the one from
the parent was used which returned the `NAME` of the parent. This
caused `TimeProcessor` objects to be deserialised into
DateTimeProcessor.
Moreover, added a restriction to run the TIME related integration tests
only in UTC timezone.

This change adds the following internal refactorings:
* wraps input analyzers into an unmodifiable map in IndexAnalyzers ctor
* removes duplicated indexSetting in IndexAnalyzers
* removes references to IndexAnalyzers from DocumentMapperParser and TypeParser.ParserContext.
It can always be retrieve it from MapperService directly in those cases
A full format for a DATETIME would be:
`2019-03-30T10:20:30.123+10:00` which is 29 chars long.
For DATE a full format would be: `2019-03-30T00:00:00.000+10:00`
which is also 29 chars long.

It is important that resync actions are not rejected on the primary even if its
`write` threadpool is overloaded. Today we do this by exposing
`registerRequestHandlers` to subclasses and overriding it in
`TransportResyncReplicationAction`. This isn't ideal because it obscures the
difference between this action and other replication actions, and also might
allow subclasses to try and use some state before they are properly
initialised. This change replaces this override with a constructor parameter to
solve these issues.
