Backport of #50927.
Closes#49653. When using _FILE environment variables to supply values
to Elasticsearch, following symlinks when checking that file permissions
are secure.
This commit merely adds the skeleton for the autoscaling project, adding
the basics to include the autoscaling module in the default
distribution, opt-in to code formatting, and a placeholder for the docs.
These policies store statistics, but since stats updating is asynchronous, it's
possible for the update from one test to bleed into a separate one. This change
switches the tests to use separate policy ids so that their stats are tracked
independently. It also relaxes the checking constraint in one of the tests.
Hopefully this:

Tests in BuildPluginIT copy the workspace but exclude the build
directories based on whether the directory string representation
includes `/build/` or not. This check is problematic if the directory
of the project has a parent directory also named `build`. The change in
this commit checks to see if the path relative to the project directory
has any path parts equal to `build`.
This change introduces a new feature for indices so that they can be
hidden from wildcard expansion. The feature is referred to as hidden
indices. An index can be marked hidden through the use of an index
setting, `index.hidden`, at creation time. One primary use case for
this feature is to have a construct that fits indices that are created
by the stack that contain data used for display to the user and/or
intended for querying by the user. The desire to keep them hidden is
to avoid confusing users when searching all of the data they have
indexed and getting results returned from indices created by the
system.
Hidden indices have the following properties:
* API calls for all indices (empty indices array, _all, or *) will not
return hidden indices by default.
* Wildcard expansion will not return hidden indices by default unless
the wildcard pattern begins with a `.`. This behavior is similar to
shell expansion of wildcards.
* REST API calls can enable the expansion of wildcards to hidden
indices with the `expand_wildcards` parameter. To expand wildcards
to hidden indices, use the value `hidden` in conjunction with `open`
and/or `closed`.
* Creation of a hidden index will ignore global index templates. A
global index template is one with a match-all pattern.
* Index templates can make an index hidden, with the exception of a
global index template.
* Accessing a hidden index directly requires no additional parameters.
Backport of #50452
This commit upgrades the OWASP HTML sanitizer used by watcher to the
latest version and also upgrades guava, which it depends on. The guava
upgrade also requires the addition of a new dependency that guava
itself requires as of version 27.0. The sanitizer's behavior has changed to
re-write these templated values with a comment that results in this output
`{<!-- -->{ctx.metadata.name}}`. This would be an issue if we attempted to
sanitize the template, but the code that uses the sanitizer runs the rendered
string through the sanitizer, which means that the templated values have
been replaced already.

When you declare an ObjectParser with top level named objects like we do
with `significant_terms` we didn't support "did you mean". This fixes
that.
Relates #50938
This commit changes our behavior so that when we receive a
request with an invalid/expired/wrong access token or API Key
we do not fallback to authenticating as the anonymous user even if
anonymous access is enabled for Elasticsearch.
If 1000 different category definitions are created for a job in
the first 100 buckets it processes then an audit warning will now
be created. (This will cause a yellow warning triangle in the
ML UI's jobs list.)
Such a large number of categories suggests that the field that
categorization is working on is not well suited to the ML
categorization functionality.
Object fields cannot be used as features. At the moment _explain
API includes them and even worse it allows it does not error when
an object field is excluded. This creates the expectation to the
user that all children fields will also be excluded while it's not
the case.
This commit omits object fields from the _explain API and also
adds an error if an object field is included or excluded.
Backport of #51115
If a transform config got lost (e.g. because the internal index disappeared) tasks could not be
stopped using transform API. This change makes it possible to stop transforms without a config,
meaning to remove the background task. In order to do so force must be set to true.
If some internal `.watcher` or so index gets created during these tests
then the shard counts on snapshot restores and creates won't match up with expectations.
Fixed by only creating the snapshot for the test index
Closes#50819
* Fix Infinite Retry Loop in loading RepositoryData
We were running into an infinite loop when trying to load corrupted (or otherwise un-loadable)
repository data for a repo that uses best effort consistency (e.g. that was just freshly mounted
as done in the test) because we kepy resetting to `-1` on `IOException`, listing and finding the broken
generation `N` and then interpreted the subsequent reset to `-1` as a concurrent change to the repository.
This moves the testing of custom significance heuristic plugins from an
`ESIntegTestCase` to an example plugin. This is *much* more "real" and
can be used as an example for anyone that needs to actually build such a
plugin. The old test had testing concerns and the example all jumbled
together.
elastic/docs#1687 added support for the `[%collapsible]` Asciidoc
attribute, which creates collapsible sections in the HTML output.
This PR makes two related changes to the nodes stats API documentation:
* Makes the response parameter sections collapsible. This allows users
to more easily navigate the page without long walls of text.
* Reorders the response parameter sections to match the default order
returned by the API.
Relates to #47524.
Adds a 'Configure text analysis' page to house tutorial content for the
analysis topic.
Also relocates the following pages as children as this new page:
* 'Test an analyzer'
* 'Configuring built-in analyzers'
* 'Create a custom analyzer'
I plan to add a tutorial for specifying index-time and search-time
analyzers to this section as part of a future PR.
This helps the topic better match the structure of
our machine learning docs, e.g.
https://www.elastic.co/guide/en/machine-learning/7.5/ml-concepts.html
This PR only includes the 'Anatomy of an analyzer' page as a 'Concepts'
child page, but I plan to add other concepts, such as 'Index time vs.
search time', with later PRs.
* Changes titles to sentence case.
* Appends pages with 'reference' to differentiate their content from
conceptual overviews.
* Moves the 'Normalizers' page to end of the Analysis topic pages.
Updates snippet to consistently use 2-space indentation. The snippet

When we receive a request with an Authorization header that contains
a Bearer token that is not generated by us or that is malformed in
some way, attempting to decode it as one of our own might cause a
number of exceptions that are not IOExceptions. This commit ensures
that we catch and log these too and call onResponse with `null, so
that we can return 401 instead of 500.
Resolves: #50497
With elastic/elasticsearch#35848, users can now retrieve total hits as an integer when the `rest_total_hits_as_int` query parameter is `true`. This is the default value.
This updates several snippet examples in the Watcher docs that used a workaround to get a total hits integer.
Updates several example snippets in the Cluster Allocation Explain API
docs to consistently use the `my_index` index.
Previously, the snippets switches from `my_index` to `idx`, which could
confuse users.

* Extend the optimizations for equalities
This commit supplements the optimisations of equalities in conjunctions
and disjunctions:
* for conjunctions, the existing optimizations with ranges are extended
with not-equalities and inequalities; these lead to a fast resolution,
the conjunction either being evaluate to a FALSE, or the non-equality
conditions being dropped as superfluous;
* optimisations for disjunctions are added to be applied against ranges,
inequalities and not-equalities; these lead to disjunction either
becoming TRUE or the equality being dropped, either as superfluous or
merged into a range/inequality.
* Adress review notes
* Fix the bug around wrongly optimizing 'a=2 OR a!=?', which only yields
TRUE for same values in equality and inequality.
* Var renamings, code style adjustments, comments corrections.
* Address further review comments. Extend optim.
- fix a few code comments;
- extend the Equals OR NotEquals optimitsation (a=2 OR a!=5 -> a!=5);
- extend the Equals OR Range optimisation on limits equality (a=2 OR
2<=a<5 -> 2<=a<5);
- in case an equality is being removed in a conjunction, the rest of
possible optimisations to test is now skipped.
* rename one var for better legiblity

The PreConfiguredTokenFilter#singletonWithVersion uses the version
internally for the token filter factories but it registers only one
instance in the cache and not one instance per version. This can lead
to exceptions like the one described in #50734 since the singleton is
created and cached using the version created of the first index
that is processed.
Remove the singletonWithVersion() methods and use the
elasticsearchVersion() methods instead.
Fixes: #50734

Backport / reimplementation of #50786 on 7.x.
Opt-in `buildSrc` for automatic formatting. This required a config tweak
in order to pick up all the Java sources, and as a result more files are
now found in the Enrich plugin, that were previously missed.
I also moved the 2 Java files in `buildSrc/src/main/groovy` into the Java
directory, which required some follow-up changes.
Backport: #50467
This commit adds the name of the current pipeline to ingest metadata.
This pipeline name is accessible under the following key: '_ingest.pipeline'.
Example usage in pipeline:
PUT /_ingest/pipeline/2
{
"processors": [
{
"set": {
"field": "pipeline_name",
"value": "{{_ingest.pipeline}}"
}
}
]
}
Closes#42106
Knowing about used analysis components and mapping types would be incredibly
useful in order to know which ones may be deprecated or should get more love.
Some field types also act as a proxy to know about feature usage of some APIs
like the `percolator` or `completion` fields types for percolation and the
completion suggester, respectively.
Replace DES with AES to align with modern encryption standards
Backport also fixs Files.readString API that is not available in Java 8
Resolves: #50843
It's possible that the index could return no settings and thus throw a
`NullPointerException`.
I wasn't able to reproduce the original issue, but this should guard
against in the future.
