Since #51905, we skip translog recovery if the local checkpoint of the
safe commit equals to the global checkpoint. This change adjusts the
test not to create a new snapshot in that case.
Closes#52221
Relates #51905
Separates the translog from the index deletion conditions (allowing the translog to be cleaned
up more eagerly), and avoids taking the write lock on the translog if no clean-up is actually
necessary.
Today we use the translog_generation of the safe commit as the minimum
required translog generation for recovery. This approach has a
limitation, where we won't be able to clean up translog unless we flush.
Reopening an already recovered engine will create a new empty translog,
and we leave it there until we force flush.
This commit removes the translog_generation commit tag and uses the
local checkpoint of the safe commit to calculate the minimum required
translog generation for recovery instead.
Closes#49970
This PR moves the majority of the Watcher REST tests under
the Watcher x-pack plugin.
Specifically, moves the Watcher tests from:
x-pack/plugin/test
x-pack/qa/smoke-test-watcher
x-pack/qa/smoke-test-watcher-with-security
x-pack/qa/smoke-test-monitoring-with-watcher
to:
x-pack/plugin/watcher/qa/rest (/test and /qa/smoke-test-watcher)
x-pack/plugin/watcher/qa/with-security
x-pack/plugin/watcher/qa/with-monitoring
Additionally, this disables Watcher from the main
x-pack test cluster and consolidates the stop/start logic
for the tests listed.
No changes to the tests (beyond moving them) are included.
3rd party tests and doc tests (which also touch Watcher)
are not included in the changes here.
We embed the :reaper project jar in the build-tools jar so we can spawn
a reaper process at build runtime. Due to this, the jar technically
isn't part of the test runtime classpath, but for input snapshotting
purposes, we should be treating it as such. Instead, because it lives
in META-INF, Gradle treats it as a normal file, which in practice means
its hash changes on every build (timestamps, etc).
This commit changes our input snapshotting strategy such that instead
we explicitly add the jar as an input to any test tasks using Gradle's
runtime classpath normalization strategy (ignore timestamps, jar entry
order, etc) and ignore the file in META-INF. This ensures that we can
properly cache test results for build-tools, why still ensuring that
changes to the :reaper project trigger reexecution of tests.
This commit changes the `index.hidden` setting from being final to a
dynamic setting. While the setting being final allows for easier
reasoning about an index, making this setting update-able has more
benefits in that we can upgrade existing indices to be hidden and it
will enable future features that would dynamically make indices hidden.
Backport of #52772
We've pretty well settled on `ContextParser` for a generic interface to
`ObjectParser`-like-things. This switches the interface used for
building parsing pipeline aggregations to `ContextParser` which saves a
couple of little wrappers around `ObjectParser`.
Adds the `?refresh=wait_for` query argument to an index API snippet in
the term vectors API docs.
This should ensure the document is indexed and available before a
subsequent term vectors API request executes.
Fixes#52814.
We were not correctly respecting the download range which lead
to the GCS SDK client closing the connection at times.
Also, fixes another instance of failing to drain the request fully before sending the response headers.
Closes#51446
Currently 3 remote cluster settings (ping interval, skip unavailable,
and compression) have a dependency on the seeds setting being
comfigured. With proxy mode, it is now possible that these settings the
seeds setting has not been configured. This commit removes this
dependency and adds new validation for these settings.
Generalize how queries on `_index` are handled at rewrite time (#52486)
Since this change refactors rewrites, I also took it as an opportunity to adrress #49254: instead of returning the same queries you would get on a keyword field when a field is unmapped, queries get rewritten to a MatchNoDocsQueryBuilder.
This change exposed a couple bugs, like the fact that the percolator doesn't rewrite queries at query time, or that the significant_terms aggregation doesn't rewrite its inner filter, which I fixed.
Closes#49254
* Smarter copying of the rest specs and tests (#52114)
This PR addresses the unnecessary copying of the rest specs and allows
for better semantics for which specs and tests are copied. By default
the rest specs will get copied if the project applies
`elasticsearch.standalone-rest-test` or `esplugin` and the project
has rest tests or you configure the custom extension `restResources`.
This PR also removes the need for dozens of places where the x-pack
specs were copied by supporting copying of the x-pack rest specs too.
The plugin/task introduced here can also copy the rest tests to the
local project through a similar configuration.
The new plugin/task allows a user to minimize the surface area of
which rest specs are copied. Per project can be configured to include
only a subset of the specs (or tests). Configuring a project to only
copy the specs when actually needed should help with build cache hit
rates since we can better define what is actually in use.
However, project level optimizations for build cache hit rates are
not included with this PR.
Also, with this PR you can no longer use the includePackaged flag on
integTest task.
The following items are included in this PR:
* new plugin: `elasticsearch.rest-resources`
* new tasks: CopyRestApiTask and CopyRestTestsTask - performs the copy
* new extension 'restResources'
```
restResources {
restApi {
includeCore 'foo' , 'bar' //will include the core specs that start with foo and bar
includeXpack 'baz' //will include x-pack specs that start with baz
}
restTests {
includeCore 'foo', 'bar' //will include the core tests that start with foo and bar
includeXpack 'baz' //will include the x-pack tests that start with baz
}
}
```
Currently we have two ways to create a GroupShardsIterator: one that will resort the iterators based on their natural ordering, and another one that will leave them in their original order. This is currently done through two constructors, one that accepts a single argument which does the sorting, and another which accepts a second boolean argument to control whether sorting should happen or not. This second constructor is only called externally to disable the sorting.
By introducing a specific method to create a sorted shard iterator we clarify and make it easier to track when we do sort and when we do not as the iterators are externally sorted.
Remove reference to an "SQL API" which could suggest that one needs to
treat this in a special way when configuring the ODBC driver.

Commit #52748 fixed a bug where percolate queries wrapped in a constant score
could report incorrect matches. This commit adds a test to check that it also fixes
the case where a percolate query is sorted by something other than score.
Closes#52618
This change fixes the incomplete backport of #46731 in 7.x (as of 7.5).
We now check if `max_children` is set on the top level nested sort and fails with an
exception if it's not the case.

* Remove TODO in MaxAgeCondition serialization
This removes the TODO with a message for any future readers regarding the code in question.
Resolves#52505
XPackLicenseState reads to necessary to validate a number of cluster
operations. This reads occasionally occur on transport threads which
should not be blocked. Currently we sychronize when reading. However,
this is unecessary as only a single piece of state is updateable. This
commit makes this state volatile and removes the locking.
Currently the shard bulk request can be rejected by the write threadpool
after a mapping update. This introduces a scenario where the mapping
listener thread will attempt to finish the request and fsync. This
thread can potentially be a transport thread. This commit fixes this
issue by forcing the finish action to happen on the write threadpool.
Fixes#51904.
Lucene's RAMDirectory has been deprecated. This commit replaces all uses of
RAMDirectory in elasticsearch with the newer ByteBuffersDirectory. Most uses
are in tests, but the percolator and painless executor may get some small speedups.
The block setup by the test could be released by the nodes cluster info
thread before the disk threshold decider was disabled, now disable
decider first.
Adds an explicit "important" admonition discouraging apps from using
cat APIs.
cat APIs are intended for human consumption via the command line or
Kibana console only. They are not intended for consumption by
applications.
Currently, date ranges queries using NOW-based date math are rewritten to
MatchAllDocs queries when being preprocessed for the percolator. However,
since we added the verification step, this can result in incorrect matches when
percolator queries are run without scores. This commit changes things to instead
wrap date queries that use NOW with a new DateRangeIncludingNowQuery.
This is a simple wrapper query that returns its delegate at rewrite time, but it can
be detected by the percolator QueryAnalyzer and be dealt with accordingly.
This also allows us to remove a method on QueryRewriteContext, and push all
logic relating to NOW-based ranges into the DateFieldMapper.
