Currently when adding a response header, we do some de-duplication, and
maybe drop the header on the floor if we have reached capacity. Yet, we
still update the thread local tracking the response headers. This is
really expensive because under the hood there is a shared reference that
we synchronize on. In the case of a request processed across many shards
in a tight loop, this contention can be detrimental to performance. We
can avoid updating the thread local in these cases though, when the
response header is duplicate of one that we have already seen, or when
it's dropped on the floor. This commit addresses these performance
issues by avoiding the unnecessary set.
As of today the Close Index API does its best to close indices,
but closing an index with ongoing recoveries might or might not
be acknowledged depending of the values of the max seq number
and global checkpoint at the time the
TransportVerifyShardBeforeClose action is executed.
These tests failed because they always expect that the index is
correctly closed on the first try, which is not always the case.
Instead we need to retry the closing until it succeed.
Closes#37571
* Fixes `testTwoNodeFirstNodeCleared` by manipulating voting config exclusions.
* Removes `testRecoveryDifferentNodeOrderStartup` since state recovery is now
handled entirely on the elected master, so the order in which the data nodes
start is irrelevant.
This test was actually passing, for the wrong reason: it asserts a
`MasterNotDiscoveredException` is thrown, expecting this to be due to a failure
to perform state recovery, but in fact it's thrown because the node is not
correctly bootstrapped.
The "include_type_name" parameter was temporarily introduced in #37285 to facilitate
moving the default parameter setting to "false" in many places in the documentation
code snippets. Most of the places can simply be reverted without causing errors.
In this change I looked for asciidoc files that contained the
"include_type_name=true" addition when creating new indices but didn't look
likey they made use of the "_doc" type for mappings. This is mostly the case
e.g. in the analysis docs where index creating often only contains settings. I
manually corrected the use of types in some places where the docs still used an
explicit type name and not the dummy "_doc" type.
This change adds deprecation warning to the indices.get_mapping API in case the
"inlcude_type_name" parameter is set to "true" and changes the parsing code in
GetMappingsResponse to parse the type-less response instead of the one
containing types. As a consequence the HLRC client doesn't need to force
"include_type_name=true" any more and the GetMappingsResponseTests can be
adapted to the new format as well. Also removing some "include_type_name"
parameters in yaml test and docs where not necessary.
Commit #37535 removed an internal restore request in favor of the
RestoreSnapshotRequest. Commit #37449 added a new test that used the
internal restore request. This commit modifies the new test to use the
RestoreSnapshotRequest.
delete and close index actions threw IllegalArgumentExceptions
when attempting to run against an index that has a snapshot
in progress.
This change introduces a dedicated SnapshotInProgressException
for these scenarios. This is done to explicitly signal to clients that
this is the reason the action failed, and it is a retryable error.
relates to #37541.
This is a continuation of #28667 and has as goal to convert all executors to propagate errors to the
uncaught exception handler. Notable missing ones were the direct executor and the scheduler. This
commit also makes it the property of the executor, not the runnable, to ensure this property. A big
part of this commit also consists of vastly improving the test coverage in this area.
This commit adds a set_priority action to the hot, warm, and cold
phases for an ILM policy. This action sets the `index.priority`
on the managed index to allow different priorities between the
hot, warm, and cold recoveries.
This commit also includes the HLRC and documentation changes.
closes#36905
This change adds a way to customize how phrase prefix queries should be created
on field types. The match phrase prefix query is exposed in field types in order
to allow optimizations based on the options set on the field.
For instance the text field uses the configured prefix field (if available) to
build a span near that mixes the original field and the prefix field on the last
position.
This change also contains a small refactoring of the match/multi_match query that
simplifies the interactions between the builders.
Closes#31921
This test failed because the refresh at the end of the test is not guaranteed to run before the
indexing is completed, and therefore there's no guarantee that the refresh will free all operations.
This triggers an assertion failure in the test clean-up, which asserts that there are no more pending
operations.
* SQL: Rename SQL data type DATE to DATETIME
SQL data type DATE has only the date part (e.g.: 2019-01-14)
without any time information. Previously the SQL type DATE was
referring to the ES DATE which contains also the time part along
with TZ information. To conform with SQL data types the data type
`DATE` is renamed to `DATETIME`, since it includes also the time,
as a new runtime SQL `DATE` data type will be introduced down the road,
which only contains the date part and meets the SQL standard.
Closes: #36440
* Address comments
Some systems default to a nofile ulimit of 65535. To reduce the pain of
deploying Elasticsearch to such systems, this commit lowers the required
limit from 65536 to 65535.
We flush quite often in testAddNewReplicas to create the safe index
commit with gaps in sequence numbers. This test is failing recently
because CI is too slow to complete 5 small flushes in 10 seconds.
This commit increases timeout for this test and also ensures to always
terminate the background indexing. The latter is to eliminate unrelated
failures if this test fails again.
Closes#37183
All tests except testRestorePersistentSettings (renamed to
testExceptionWhenRestoringPersistentSettings) worked fine.
testExceptionWhenRestoringPersistentSettings re-written to use a custom
setting, because "minimum master node" setting is no longer available
in Zen2. It turns out there is no good replacement for "minimum master
node" setting for this test, that's why the custom setting is
introduced.
Unfortunately, there is #37485 bug and currently
RestoreService does not perform setting validation. That's why the
test is annotated with @AwaitsFix, the idea is to merge this commit and
then fix the issue and enable the test. (The test passes with a simple
fix, that adds a single line to RestoreService).
When reporting metadata, several clients have issues with the 'ALIAS'
type. To improve compatibility and be consistent with the ANSI SQL
expectations and because they are similar, aliases targets are now
reported as views.
Close#37422
Currently all proxied actions are denied for the `SystemPrivilege`.
Unfortunately, there are use cases (CCR) where we would like to proxy
actions to a remote node that are normally performed by the
system context. This commit allows the system context to perform
proxy actions if they are actions that the system context is normally
allowed to execute.
PutWatchResponse did not allow unknown fields. This commit fixes the
test and ConstructingObjectParser such that it does now allow unknown
fields.

In order to distinguish the ES-SQL type from the standard SQL type
add a new ES-SQL column that will make clear this distingstion,
e.g.: datetime vs TIMSTAMP
Fixes: #37519
Currently it takes a type, but this isn't really needed now that indices can
have at most one type. The only downside is that we might return a different
error when trying to index into a type that doesnt't exist yet.
This commit removes some leniency from REST handling where we move to
reject all requests that have a body where the body is not used during
the course of handling the request. For example,
DELETE /index
{
"query" : {
"term" : {
"field" : "value"
}
}
}
is now rejected.
This introduces a new ssl-config library that can parse
and validate SSL/TLS settings and files.
It supports the standard configuration settings as used in the
Elastic Stack such as "ssl.verification_mode" and
"ssl.certificate_authorities" as well as all file formats used
in other parts of Elasticsearch security (such as PEM, JKS,
PKCS#12, PKCS#8, et al).
