Deprecates the optimize_bbox parameter on geodistance queries. This has no longer been needed since version 2.2 because lucene geo distance queries (postings and LatLonPoint) already optimize by bounding box.
In 1e91f3b we disabled annotation processors globally. However, some
project like JMH need annotation processing, so we add an ability to
selectively enabled annotation processing for certain projects by
setting an external property in the corresponding Gradle build script.
Note that `javac` would allow to set a specific annotation processor
with the command line option `-processor`. However, due to a bug in
Gradle we we cannot use this option and need to enable all annotation
processors.
Fix field examples to make documents actually visible
This commit adds refresh calls to field examples an removes not working
`_routing` and `_field_names` script access.
Closes#20118
Catching and suppressing AlreadyClosedException from Lucene is dangerous because it can mean there is a bug in ES since ES should normally guard against invoking Lucene classes after they were closed.
I reviewed the cases where we catch AlreadyClosedException from Lucene and removed the ones that I believe are not needed, or improved comments explaining why ACE is OK in that case.
I think (@s1monw can you confirm?) that holding the engine's readLock means IW will not be closed, except if disaster strikes (failEngine) at which point I think it's fine to see the original ACE in the logs?
Closes#19861
When a SearchContext is closed it's reader / searcher reference is closed too.
If this happens while a search is accessing it's reader reference it can lead
to an unexpected `AlreadyClosedException` or worst case, an already closed MMapDirectory
is access causing a `SIGSEV` like in #20008 (even though the window for this is very small).
SearchContext can be closed concurrently if:
* an index is deleted / removed from the node
* a search context is idle for too long and is cleaned by the reaper
* an explicit freeContext message is received
This change adds reference counting to the SearchContext base class and it's used
inside SearchService each time the context is accessed.
Closes#20008
the setting in elasticsearch.yml, so that when a user uncomments
out a setting by just removing the #, the setting actually
takes effect. Before, it was very easy to uncomment out a
setting by just removing the #, leaving a single whitespace
character before the setting name, which would cause the
setting to not get picked up by Elasticsearch.
Closes#20090
This includes:
- All regular numeric types such as int, long, scaled-float, double, etc
- IP addresses
- Dates
- Geopoints and Geoshapes

Adds ignoreUnavailable to the snapshot status API to be consistent
with the get snapshots API which has a similar parameter. If
ignoreUnavailable is set to true, then the snapshot status request
will ignore any snapshots that were not found in the repository,
instead of throwing a SnapshotMissingException.
Closes#18522
StartupException overrides Throwable#printStackTrace(PrintStream) but
not Throwable#printStackTrace(PrintWriter). The former override is used
when the JVM terminates with an exception, but the latter override can
be used in some logging frameworks when rendering an exception (e.g.,
log4j). This commit adds an override for the latter, with the behavior
for the two overrides being the same.
This commit renames StartupError to StartupException. This rename is due
to the fact that this class inherits from Exception not Error in the
Throwable class hierarchy.
This commit removes the minimum master nodes bootstrap check. The
motivation for this check was to raise awareness of the minimum master
nodes setting but this check gives a false sense of security because
it's too easy to set the setting to one when first standing up a cluster
and never update it when adding master-eligible nodes, or have it out of
sync on various nodes and still pass this check. Since this check does
not have the security that other bootstrap checks provide, it should be
removed in favor of a stronger guarantee in the future. We do log a
warning if an election occurs with minimum master nodes less than a
quorum of master-eligible nodes that participated in an election and
this is the best that we can do right now.
Relates #20082
This commit sets external nodes for integration tests to default to
using 512m of heap. This can be overridden using tests.heap.size (a
system property that we already use elesewhere for setting the size of
the heap for the test runner) or using tests.jvm.argline (this last one
takes precedence).
This commit sets the default min heap equal to the default max
heap. This is to align the default out-of-box settings with the heap
size bootstrap check.
Some time ago, AllocationService.reroute was changed to not only return updates to the routing table but also to the metadata (which contain primary terms and in-sync allocation ids). A lot of test code still only updates the routing table though, which is fixed by this PR.
How index templates match is currently controlled by the
IndexTemplateFilter interface. It is pluggable, to add additional
filter implementations to the default glob matcher.
This change removes the IndexTemplateFilter interface completely. This
is a very esoteric extension point, and not worth maintaining. Instead,
any improvements should be made to all of our glob matching.
This change moves custom ShardsAllocators from registration on
ClusterModule, to implementing getShardsAllocators() in ClusterPlugin.
It also removes the legacy alias "even_shard" for the balanced allocator
which was removed in 2.0.
