This commit adds cross-settings validation for the low/high/flood stage
disk watermark settings. This validation was enabled by the introduction
of multiple settings validation.
Relates #25600
The created and found fields in index and delete responses became obsolete after the introduction of the result field in index, update and delete responses (#19566).
After deprecating the created and found fields in 5.x (#19633), now they are removed.
Fixes#19630
* Improved REST endpoint exception handling, see #15335
Also improved OPTIONS http method handling to better conform with the
http spec.
* Tidied up formatting and comments
See #15335
* Tests for #15335
* Cleaned up comments, added section number
* Swapped out tab indents for space indents
* Test class now extends ESSingleNodeTestCase
* Capture RestResponse so it can be examined in test cases
Simple addition to surface the RestResponse object so we can run tests
against it (see issue #15335).
* Refactored class name, included feedback
See #15335.
* Unit test for REST error handling enhancements
Randomizing unit test for enhanced REST response error handling. See
issue #15335 for more details.
* Cleaned up formatting
* New constructor to set HTTP method
Constructor added to support RestController test cases.
* Refactored FakeRestRequest, streamlined test case.
* Cleaned up conflicts
* Tests for #15335
* Added functionality to ignore or include path wildcards
See #15335
* Further enhancements to request handling
Refactored executeHandler to prioritize explicit path matches. See
#15335 for more information.
* Cosmetic fixes
* Refactored method handlers
* Removed redundant import
* Updated integration tests
* Refactoring to address issue #17853
* Cleaned up test assertions
* Fixed edge case if OPTIONS method randomly selected as invalid method
In this test, an OPTIONS method request is valid, and should not return
a 405 error.
* Remove redundant static modifier
* Hook the multiple PathTrie attempts into RestHandler.dispatchRequest
* Add missing space
* Correctly retrieve new handler for each Trie strategy
* Only copy headers to threadcontext once
* Fix test after REST header copying moved higher up
* Restore original params when trying the next trie candidate
* Remove OPTIONS for invalidHttpMethodArray so a 405 is guaranteed in tests
* Re-add the fix I already added and got removed during merge :-/
* Add missing GET method to test
* Add documentation to migration guide about breaking 404 -> 405 changes
* Explain boolean response, pull into local var
* fixup! Explain boolean response, pull into local var
* Encapsulate multiple HTTP methods into PathTrie<MethodHandlers>
* Add PathTrie.retrieveAll where all matching modes can be retrieved
Then TrieMatchingMode can be package private and not leak into RestController
* Include body of error with 405 responses to give hint about valid methods
* Fix missing usageService handler addition
I accidentally removed this :X
* Initialize PathTrieIterator modes with Arrays.asList
* Use "== false" instead of !
* Missing paren :-/
Today when we run out of disk all kinds of crazy things can happen
and nodes are becoming hard to maintain once out of disk is hit.
While we try to move shards away if we hit watermarks this might not
be possible in many situations. Based on the discussion in #24299
this change monitors disk utilization and adds a flood-stage watermark
that causes all indices that are allocated on a node hitting the flood-stage
mark to be switched read-only (with the option to be deleted). This allows users to react on the low disk
situation while subsequent write requests will be rejected. Users can switch
individual indices read-write once the situation is sorted out. There is no
automatic read-write switch once the node has enough space. This requires
user interaction.
The flood-stage watermark is set to `95%` utilization by default.
Closes#24299
Add an Important admonition for upgrading via the command line
using the Windows MSI Installer. This calls out the need to pass
the same command line options for an upgrade as were used for
the initial installation.
* Adds check for negative search request size
This change adds a check to `SearchSourceBuilder` to throw and exception if the size set on it is set to a negative value.
Closes#22530
* fix error in reindex
* update re-index tests
* Addresses review comment
* Fixed tests
* Added random negative size test
* Fixes test
This commit adds a note to the docs regarding explicilty setting a
publish host if the network.host setting results in multiple bind
addresses.

Currently QueryParseContext is only a thin wrapper around an XContentParser that
adds little functionality of its own. I provides helpers for long deprecated
field names which can be removed and two helper methods that can be made static
and moved to other classes. This is a first step in helping to remove
QueryParseContext entirely.
Expand `/_cat/nodes` with already present information about available disk space `diskAvail` (alias: `d`, `disk`) by:
* `diskTotal` (alias `dt`): total disk space
* `diskUsed` (alias `du`): used disk space (`diskTotal - diskAvail`)
* `diskUsedPercent` (alias `dup`): used disk space percentage
Note: The available disk space is the number of bytes available to the node's Java virtual machine. The size might be smaller than the real one. That means the used disk space (percentage) is larger.
Closes#21679
We previously tried to maintain (while not formally supporting) 32-bit
support, although we never tested this anywhere in CI. Since we do not
formally support this, and 32-bit usage is very low, we have elected to
no longer maintain 32-bit support. This commit removes any implication
of 32-bit support.

Changed `rescore`s to `rescore` requests as an backtick followed by the s character appears to be interpreted as an apostrophe which then leads to an unbalanced backtick for the next code span in the remainder of the paragraph
Closes#25443
This commit removes the default path settings for data and logs. With
this change, we now ship the packages with these settings set in the
elasticsearch.yml configuration file rather than going through the
default.path.data and default.path.logs dance that we went through in
the past.

This commit removes path.conf as a valid setting and replaces it with a
command-line flag for specifying a non-default path for configuration.

#25147 added the translog deletion policy but didn't enable it by default. This PR enables a default retention of 512MB (same maximum size of the current translog) and an age of 12 hours (i.e., after 12 hours all translog files will be deleted). This increases to chance to have an ops based recovery, even if the primary flushed or the replica was offline for a few hours.
In order to see which parts of the translog are committed into lucene the translog stats are extended to include information about uncommitted operations.
Views now include all translog ops and guarantee, as before, that those will not go away. Snapshotting a view allows to filter out generations that are not relevant based on a specific sequence number.

The `document_type` parameter is no longer required to be specified,
because by default from 6.0 only a single type is allowed. (`index.mapping.single_type` defaults to `true`)
* [Analysis] Parse synonyms with the same analysis chain
Synonym Token Filter / Synonym Graph Filter tokenize synonyms with whatever tokenizer and token filters appear before it in the chain.
Close#7199
* Add MSI installation to documentation
Move installation documentation for Windows with the .zip archive into the zip and tar installation documentation, and clearly indicate any differences for installing on macOS/Linux and Windows.
* Separate out installation with .zip on Windows
With #23997 we have introduced a new internal index option that allows to resolve index expressions only against concrete indices while ignoring aliases. Such index option was applied to IndicesAliasesRequest, so that the index part of alias actions would only be resolved against concrete indices.
Same is done in this commit with delete index request. Deleting aliases has always been confusing as some users expect it to only remove the alias from the index (which has its own specific API). Even worse, in case of filtered aliases, deleting an alias may leave users with the expectation that only the documents that match the filter are deleted, which was never the case. To address all this confusion, delete index api works now only against concrete indices. WIldcard expressions will be only resolved against concrete index, as if aliases didn't exist. If one tries to delete against an alias, an IndexNotFoundException will be thrown regardless of whether the alias exists or not, as a concrete index with such a name doesn't exist.
