* Improoce how log is tailed in testclusters on failure
- only print last few lines
- print all errors and warnings
- compact repeating errors and warnings
* Reduce Number of List Calls During Snapshot Create and Delete
Some obvious cleanups I found when investigation the API call count
metering:
* No need to get the latest generation id after loading latest
repository data
* Loading RepositoryData already requires fetching the latest
generation so we can reuse it
* Also, reuse list of all root blobs when fetching latest repo
generation during snapshot delete like we do for shard folders
* Lastly, don't try and load `index--1` (N = -1) repository data, it
doesn't exist -> just return the empty repo data initially
Simplifies AbstractSimpleTransportTestCase to use JVM-local ports and also adds an assertion so
that cases like #44134 can be more easily debugged. The likely reason for that one is that a test,
which was repeated again and again while always spawning a fresh Gradle worker (due to Gradle
daemon) kept increasing Gradle worker IDs, causing an overflow at some point.
Now that ML job configs are stored in an index rather than
cluster state, availability of the .ml-config index is very
important to the operation of ML. When a cluster starts up
the ML persistent tasks will be considered for node
assignment very early on. It is best in this case if
assignment is deferred until after the .ml-config index is
available.
The introduction of data frame analytics jobs has made this
problem worse, because anomaly detection jobs already waited
for the primary shards of the .ml-state, .ml-anomalies-shared
and .ml-meta indices to be available before doing node
assignment, and by coincidence this would probably lead to
the primary shards of .ml-config also being searchable. But
data frame analytics jobs had no other index checks prior to
this change.
This fixes problem 2 of #44156
* Improve Repository Consistency Check in Tests (#44099)
* Check that index metadata as well as snapshot metadata always exists
when referenced by other metadata
* Fix SnapshotResiliencyTests on ExtraFS (#44113)
* As a result of #44099 we're now checking more directories and have to
ignore the `extraN` folders for those like we do for indices already
* Closes#44112
* The incompatible snapshots logic was created to track 1.x snapshots that
became incompatible with 2.x
* It serves no purpose at this point
* It adds an additional GET request to every loading of
RepositoryData (from loading the incompatible snapshots blob)
By default, we don't check ranges while indexing geo_shapes. As a
result, it is possible to index geoshapes that contain contain
coordinates outside of -90 +90 and -180 +180 ranges. Such geoshapes
will currently break SQL and ML retrieval mechanism. This commit removes
these restriction from the validator is used in SQL and ML retrieval.
* Add WARN Logging if Mock Network Accepts Huge Number of Connections
* As discussed, added warn logging to rule out endless accept loops for #43387
* Had to handle it by the relatively awkward override in the mock nio
because we don't have logging in the NIO module where
(`ServerChannelContext` lives)
The base classes for transport requests and responses currently
implement Streamable and Writeable. The writeTo method on these base
classes is implemented with an empty implementation. Not only does this
complicate subclasses to think they need to call super.writeTo, but it
also can lead to not implementing writeTo when it should have been
implemented, or extendiong one of these classes when not necessary,
since there is nothing to actually implement.
This commit removes the empty writeTo from these base classes, and fixes
subclasses to not call super and in some cases implement an empty
writeTo themselves.

* Test fixtures improovements
Don't disable some of the precommit tasks on fixtures.
This no longer makes sense now that a project can both produce and use a
fixture.
In order for this to be possible, had to add an additional configuration
to make JarHell class accessible to the task even if it's not a
dependency of the project and fix some of the third party audit fallout
from #43671 which wasn't detected at the time due to the issue being
fixed here.
Closes#43918
AggregatorFactory was generic over itself, but it doesn't appear we
use this functionality anywhere (e.g. to allow the super class
to declare arguments/return types generically for subclasses to
override). Most places use a wildcard constraint, and even when a
concrete type is specified it wasn't used.
But since AggFactories are widely used, this led to
the generic touching many pieces of code and making type signatures
fairly complex
PrimaryAllocationIT#testForceStaleReplicaToBePromotedToPrimary
relies on the flushing when a shard is no long assigned. This behavior,
however, can be randomly disabled in MockInternalEngine.
Closes#44049
When the ML memory tracker is refreshed and a refresh is
already in progress the idea is that the second and
subsequent refresh requests receive the same response as
the currently in progress refresh.
There was a bug that if a refresh failed then the ML
memory tracker's view of whether a refresh was in progress
was not reset, leading to every subsequent request being
registered to receive a response that would never come.
This change makes the ML memory tracker pass on failures
as well as successes to all interested parties and reset
the list of interested parties so that further refresh
attempts are possible after either a success or failure.
This fixes problem 1 of #44156
The `ShardFailedClusterStateTaskExecutor` fails some shards, which performs a
reroute, but then sometimes schedules a followup reroute. It's not clear from
the code why this followup is necessary, so this commit adds a short comment
describing why it's necessary.
This commit documents the backup and restore of a cluster's
security configuration.
It is not possible to only backup (or only restore) security
configuration, independent to the rest of the cluster's conf,
so this describes how a full configuration backup&restore
will include security as well. Moreover, it explains how part
of the security conf data resides on the special .security
index and how to backup that using regular data snapshot API.

Custom timestamp overrides provided to the find_file_structure
endpoint produced an invalid Grok pattern if the fractional
seconds separator was a dot rather than a comma or colon.
This commit fixes that problem and adds tests for this sort
of timestamp override.
Fixes#44110
This commit replaces usages of Streamable with Writeable for the
MultiSearchRequest class.
I ran into this when developing a custom action that reuses
MultiSearchRequest in the enrich branch.
Relates to #34389
Previously a data frame transform would check whether the
source index was changed every 10 seconds. Sometimes it
may be desirable for the check to be done less frequently.
This commit increases the default to 60 seconds but also
allows the frequency to be overridden by a setting in the
data frame transform config.
Today the `ClusterInfoService` requires the `DiskThresholdMonitor` at
construction time so that it can notify it when nodes report changes in their
disk usage, but this is awkward to construct: the `DiskThresholdMonitor`
requires a `RerouteService` which requires an `AllocationService` which comees
from the `ClusterModule` which requires the `ClusterInfoService`.
Today we break the cycle with a `LazilyInitializedRerouteService` which is
itself a little ugly. This commit replaces this with a more traditional
subject/observer relationship between the `ClusterInfoService` and the
`DiskThresholdMonitor`.
Today `testOnlyBlocksOnConnectionsToNewNodes` fails (extremely rarely) if the
last attempt to connect to `node0` is delayed for so long that the test runs
`nodeConnectionsBlocks.clear()` before the connection attempt obtains the
expected connection block. We can turn this into a reliable failure with this
delay:

This commit reverts the extra logging introduced in #43979 and fixes this
failure by waiting for the connection attempt to hit the barrier before
removing it.
Fixes#40170
Since #42636 we no longer treat connections specially when simulating a
blackholed connection. This means that at the end of the safety phase we may
have just started a connection attempt which will time out, but the default
timeout is 30 seconds, much longer than the 2 seconds we normally allow for
post-safety-phase discovery. This commit adds time for such a connection
attempt to time out.
It also fixes some spurious logging of `this` that now refers to an object with
an unhelpful `toString()` implementation introduced in #42636.
Fixes#44073
Refactor ScrollableHitSource to pump data out and have a simplified
interface (callers should no longer call startNextScroll, instead they
simply mark that they are done with the previous result, triggering a
new batch of data). This eases making reindex resilient, since we will
sometimes need to rerun search during retries.
Relates #43187 and #42612
Today the `index.routing.allocation.initial_recovery._id` setting can only be
set on indices that are the result of a shrink, but the filtered allocation
decider also applies this filter to shards with a recovery source of
`EMPTY_STORE`. The only way to have this setting set while the recovery source
is `EMPTY_STORE` is to force-allocate an empty primary, but such a forced
allocation ignores this allocation decider.
This commit simplifies the allocation decider so that the `initial_recovery`
setting only applies to shards with a recovery source of `LOCAL_SHARDS`.
