Uses the new sorting (#20658) in the `_cat` API to support all use
cases natively. We can still resort to piping things through `sort`
if we need to, but we don't have to for basic stuff like sorting!
Removes a non-existant file from the non-`// CONSOLE` list. If you
remove all the non-`// CONSOLE` snippets from a file it must be
removed from the whitelist for the build to pass. Removing the file
entirely counts as removing the snippets.

This causes the snippets to be tested during the build and gives
helpful links to the reader to open the docs in console or copy them
as curl commands.

After this is merged there will be no unconvereted snippets outside
of `reference`.

This tracks the snippets that probably should be converted to
`// CONSOLE` or `// TESTRESPONSE` and fails the build if the list
of files with such snippets doesn't match the list in `docs/build.gradle`.
Setting the file looks like
```
/* List of files that have snippets that probably should be converted to
* `// CONSOLE` and `// TESTRESPONSE` but have yet to be converted. Try and
* only remove entries from this list. When it is empty we'll remove it
* entirely and have a party! There will be cake and everything.... */
buildRestTests.expectedUnconvertedCandidates = [
'plugins/discovery-azure-classic.asciidoc',
...
'reference/search/suggesters/completion-suggest.asciidoc',
]
```
This list is in `build.gradle` because we expect it to be fairly
temporary. In a few months we'll have converted all of the docs and won't
ned it any more.
From now on if you add now docs that contain a snippet that shows an
interaction with elasticsearch you have three choices:
1. Stick `// CONSOLE` on the interactions and `// TESTRESPONSE` on the
responses. The build (specifically (`gradle docs:check`) will test that
these interactions "work". If there isn't a `// TESTRESPONSE` snippet
then "work" just means "Elasticsearch responds with a 200-level response
code and no `WARNING` headers. This is way better than nothing.
2. Add `// NOTCONSOLE` if the snippet isn't actually interacting with
Elasticsearch. This should only be required for stuff like javascript
source code or `curl` against an external service like AWS or GCE. The
snippet will not get "OPEN IN CONSOLE" or "COPY AS CURL" buttons or be
tested.
3. Add `// TEST[skip:reason]` under the snippet. This will just skip the
snippet in the test phase. This should really be reserved for snippets
where we can't test them because they require an external service that
we don't have at testing time.
Please, please, please, please don't add more things to the list. After
all, it sais there'll be cake when we remove it entirely!

Most of the examples in the pipeline aggregation docs use a small
"sales" test data set and I converted all of the examples that use
it to `// CONSOLE`. There are still a bunch of snippets in the pipeline
aggregation docs that aren't `// CONSOLE` so they aren't tested. Most
of them are "this is the most basic form of this aggregation" so they
are more immune to errors and bit rot then the examples that I converted.
I'd like to do something with them as well but I'm not sure what.
Also, the moving average docs and serial diff docs didn't get a lot of
love from this pass because they don't use the test data set or follow
the same general layout.

When compiling many dynamically changing scripts, parameterized
scripts (<https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-scripting-using.html#prefer-params>)
should be preferred. This enforces a limit to the number of scripts that
can be compiled within a minute. A new dynamic setting is added -
`script.max_compilations_per_minute`, which defaults to 15.
If more dynamic scripts are sent, a user will get the following
exception:
```json
{
"error" : {
"root_cause" : [
{
"type" : "circuit_breaking_exception",
"reason" : "[script] Too many dynamic script compilations within one minute, max: [15/min]; please use on-disk, indexed, or scripts with parameters instead",
"bytes_wanted" : 0,
"bytes_limit" : 0
}
],
"type" : "search_phase_execution_exception",
"reason" : "all shards failed",
"phase" : "query",
"grouped" : true,
"failed_shards" : [
{
"shard" : 0,
"index" : "i",
"node" : "a5V1eXcZRYiIk8lecjZ4Jw",
"reason" : {
"type" : "general_script_exception",
"reason" : "Failed to compile inline script [\"aaaaaaaaaaaaaaaa\"] using lang [painless]",
"caused_by" : {
"type" : "circuit_breaking_exception",
"reason" : "[script] Too many dynamic script compilations within one minute, max: [15/min]; please use on-disk, indexed, or scripts with parameters instead",
"bytes_wanted" : 0,
"bytes_limit" : 0
}
}
}
],
"caused_by" : {
"type" : "general_script_exception",
"reason" : "Failed to compile inline script [\"aaaaaaaaaaaaaaaa\"] using lang [painless]",
"caused_by" : {
"type" : "circuit_breaking_exception",
"reason" : "[script] Too many dynamic script compilations within one minute, max: [15/min]; please use on-disk, indexed, or scripts with parameters instead",
"bytes_wanted" : 0,
"bytes_limit" : 0
}
}
},
"status" : 500
}
```
This also fixes a bug in `ScriptService` where requests being executed
concurrently on a single node could cause a script to be compiled
multiple times (many in the case of a powerful node with many shards)
due to no synchronization between checking the cache and compiling the
script. There is now synchronization so that a script being compiled
will only be compiled once regardless of the number of concurrent
searches on a node.

This change removes the multiple ways that plugins can be added to the
integ test cluster. It also removes the use of the default
configuration, and instead adds a zip configuration to all plugins. This
will enable using project substitutions with plugins, which must be done
with the default configuration.
This adds a remote option to reindex that looks like
```
curl -POST 'localhost:9200/_reindex?pretty' -d'{
"source": {
"remote": {
"host": "http://otherhost:9200"
},
"index": "target",
"query": {
"match": {
"foo": "bar"
}
}
},
"dest": {
"index": "target"
}
}'
```
This reindex has all of the features of local reindex:
* Using queries to filter what is copied
* Retry on rejection
* Throttle/rethottle
The big advantage of this version is that it goes over the HTTP API
which can be made backwards compatible.
Some things are different:
The query field is sent directly to the other node rather than parsed
on the coordinating node. This should allow it to support constructs
that are invalid on the coordinating node but are valid on the target
node. Mostly, that means old syntax.
We weren't doing it before because we weren't starting the plugins.
Now we are.
The hardest part of this was handling the files the tests expect
to be on the filesystem. extraConfigFiles was broken.
Two of the snippets in validate weren't working properly so they are
marked as skip and linked to this:
https://github.com/elastic/elasticsearch/issues/18254
We didn't properly handle empty parameter values. We were sending
them as the literal string "null". Now we do better and send them
as the empty string.
This makes it much easier to apply to other projects.
Fixes to doc tests infrastructure:
* Fix comparing lists. Was totally broken.
* Fix order of actual vs expected parameters.
* Allow multiple `// TESTRESPONSE` lines with substitutions to join
into one big list of subtitutions. This makes lets the docs look
tidier.
* Exclude build from snippet scanning
* Allow subclasses of ESRestTestCase access to the admin execution context
Adds infrastructure so `gradle :docs:check` will extract tests from
snippets in the documentation and execute the tests. This is included
in `gradle check` so it should happen on CI and during a normal build.
By default each `// AUTOSENSE` snippet creates a unique REST test. These
tests are executed in a random order and the cluster is wiped between
each one. If multiple snippets chain together into a test you can annotate
all snippets after the first with `// TEST[continued]` to have the
generated tests for both snippets joined.
Snippets marked as `// TESTRESPONSE` are checked against the response
of the last action.
See docs/README.asciidoc for lots more.
Closes#12583. That issue is about catching bugs in the docs during build.
This catches *some* bugs in the docs during build which is a good start.
