G1GC will use humongous allocations when an allocation exceeds half the
chosen region size, which is minimum 1MB. By reducing the recovery
buffer size by 16 bytes we ensure that the recovery buffer is never
allocated as a humongous allocation.
A previous commit taught Elasticsearch packages to respect ES_PATH_CONF
during installs. Missed in that commit was respecting ES_PATH_CONF on
upgrades. This commit does that. Additionally, while ES_PATH_CONF is not
currently used in pre-install, this commit adds respect to the preinst
script in case we do in the future.
In the yaml cluster upgrade tests, we start a scroll in a mixed-version cluster,
then attempt to continue the scroll after the upgrade is complete. This test
occasionally fails because the scroll can expire before the cluster is done
upgrading.
The current scroll keep-alive time 5m. This PR bumps it to 10m, which gives a
good buffer since in failing tests the time was only exceeded by ~30 seconds.
Addresses #46529.
Today we do not consider trimAboveSeqNo when calculating the translog
generation of an index commit. If there is no new indexing after the
primary promotion, then we won't be able to clean up the translog.
Backport of #49612.
The current Docker entrypoint script picks up environment variables and
translates them into -E command line arguments. However, since any tool
executes via `docker exec` doesn't run the entrypoint, it results in
a poorer user experience.
Therefore, refactor the env var handling so that the -E options are
generated in `elasticsearch-env`. These have to be appended to any
existing command arguments, since some CLI tools have subcommands and
-E arguments must come after the subcommand.
Also extract the support for `_FILE` env vars into a separate script, so
that it can be called from more than once place (the behaviour is
idempotent).
Finally, add noop -E handling to CronEvalTool for parity, and support
`-E` in MultiCommand before subcommands.
The testclusters shutdown code was killing child processes
of the ES JVM before the ES JVM. This causes any running
ML jobs to be recorded as failed, as the ES JVM notices that
they have disconnected from it without being told to stop,
as they would if they crashed. In many test suites this
doesn't matter because the test cluster will never be
restarted, but in the case of upgrade tests it makes it
impossible to test what happens when an ML job is running
at the time of the upgrade.
This change reverses the order of killing the ES process
tree such that the parent processes are killed before their
children. A list of children is stored before killing the
parent so that they can subsequently be killed (if they
don't exit by themselves as a side effect of the parent
dying).
Backport of #50175
With #45689 making it so that index metadata is written
after all shards have been snapshotted we can't delete indices
that are part of the upcoming snapshot finalization any longer
and it is not sufficient to check if all shards of an index have been
snapshotted before deciding that it is safe to delete it.
This change forbids deleting any index that is in the process of being
snapshot to avoid issues during snapshot finalization.
Relates #50200 (doesn't fully fix yet because we're not fixing the `partial=true`
snapshot case here
Executing the data frame analytics _explain API with a config that contains
a field that is not in the includes list but at the same time is the excludes
list results to trying to remove the field twice from the iterator. That causes
an `IllegalStateException`. This commit fixes this issue and adds a test that
captures the scenario.
Backport of #50192
* Remove BlobContainer Tests against Mocks
Removing all these weird mocks as asked for by #30424.
All these tests are now part of real repository ITs and otherwise left unchanged if they had
independent tests that didn't call the `createBlobStore` method previously.
The HDFS tests also get added coverage as a side-effect because they did not have an implementation
of the abstract repository ITs.
Closes#30424
Lucene 8.4 added support for "CONTAINS", therefore in this commit those
changes are integrated in Elasticsearch. This commit contains as well a
bug fix when querying with a geometry collection with "DISJOINT" relation.
The release builds use a production license key, and our rest test load
licenses that are signed by the dev license key.
This change adds the new enterprise license Rest tests to the
blacklist on release builds.
Backport of: #50163
Since 7.4, we switch from translog to Lucene as the source of history
for peer recoveries. However, we reduce the likelihood of
operation-based recoveries when performing a full cluster restart from
pre-7.4 because existing copies do not have PPRL.
To remedy this issue, we fallback using translog in peer recoveries if
the recovering replica does not have a peer recovery retention lease,
and the replication group hasn't fully migrated to PRRL.
Relates #45136
Today we do not use retention leases in peer recovery for closed indices
because we can't sync retention leases on closed indices. This change
allows that ability and adjusts peer recovery to use retention leases
for all indices with soft-deletes enabled.

This adds a new field for the inference processor.
`warning_field` is a place for us to write warnings provided from the inference call. When there are warnings we are not going to write an inference result. The goal of this is to indicate that the data provided was too poor or too different for the model to make an accurate prediction.
The user could optionally include the `warning_field`. When it is not provided, it is assumed no warnings were desired to be written.
The first of these warnings is when ALL of the input fields are missing. If none of the trained fields are present, we don't bother inferencing against the model and instead provide a warning stating that the fields were missing.
Also, this adds checks to not allow duplicated fields during processor creation.
This exchanges the direct use of the `Client` for `ResultsPersisterService`. State doc persistence will now retry. Failures to persist state will still not throw, but will be audited and logged.
This commit fixes a bug that caused the data frame analytics
_explain API to time out in a multi-node setup when the source
index was missing. When we try to create the extracted fields detector,
we check the index settings. If the index is missing that responds
with a failure that could be wrapped as a remote exception.
While we unwrapped correctly to check if the cause was an
`IndexNotFoundException`, we then proceeded to cast the original
exception instead of the cause.
Backport of #50176
This test was fixed as part of #49736 so that it used a
TokenService mock instance that was enabled, so that token
verification fails because the token is invalid and not because
the token service is not enabled.
When the randomly generated token we send, decodes to being of
version > 7.2 , we need to have mocked a GetResponse for the call
that TokenService#getUserTokenFromId will make, otherwise this
hangs and times out.
This commit sets xpack.security.ssl.diagnose.trust to false in all
the nodes of our TestClusters when running integTest. This is needed
in 7.x because setting xpack.security.ssl.diagnose.trust to true
wraps SunJSSE TrustManager with our own DiagnosticTrustManager and
this is not allowed when SunJSSE is in FIPS mode.
An alternative would be to set `xpack.security.fips.enabled` to
true which would also implicitly disable
xpack.security.ssl.diagnose.trust but would have additional effects
(would require that we set PBKDF2 for password hashing algorithm in
all test clusters, would prohibit using JKS keystores in nodes even
if relevant tests have been muted in FIPS mode etc.)
A recent change around date parsing (#46675) made it stricter, so we should now also
catch DateTimeExceptions in DateFieldMapper and ignore those when the
`ignore_malformed` option is set.
Closes#50081
We respect ES_PATH_CONF everywhere except package install. This commit
addresses this by respecting ES_PATH_CONF when installing the RPM/Debian
packages.
Today the HTTP exporter settings without the exporter type having been
configured to HTTP. When it is time to initialize the exporter, we can
blow up. Since this initialization happens on the cluster state applier
thread, it is quite problematic that we do not reject settings updates
where the type is not configured to HTTP, but there are HTTP exporter
settings configured. This commit addresses this by validating that the
exporter type is not only set, but is set to HTTP.
The "code_user" and "code_admin" reserved roles existed to support
code search which is no longer included in Kibana.
The "kibana_system" role included privileges to read/write from the
code search indices, but no longer needs that access.

This commit tweaks the workaround introduced in #49211 to support
Gradle 6.0. In the workaround, we specifically override the address
the Gradle daemon binds to by passing the desired address via the
OPENSHIFT_IP environment variable. This works fine for builds using
Gradle 6.0, but for older Gradle versions this causes issues with
inter-daemon communication, specifically when we build BWC branches
not on Gradle 6.0. The fix here is to strip that environment variable
out when building the target BWC branch if that branch is on an
older Gradle version.
This is all temporary and will be removed when this bug fix is released
in Gradle 6.1.

When decoupling the pipeline reduction from regular agg reduction,
MultiBucket aggs were modified to reduce their bucket's pipeline
aggs first before reducing the sibling aggs. This modification
was missed on SingleBucket aggs, meaning any SingleBucket would
fail to reduce any pipeline sub-aggs
The example snippets in the percentile rank agg docs use a test dataset
named `latency`, which is generated from docs/gradle.build.
At some point the dataset and example snippets were updated, but the
text surrounding the snippets was not. This means the text and the
example snippets shown no longer match up.
This corrects that by changing the snippets using /TESTRESPONSE magic comments.
