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.

Today when parsing a request, Elasticsearch silently ignores incorrect
(including parameters with typos) or unused parameters. This is bad as
it leads to requests having unintended behavior (e.g., if a user hits
the _analyze API and misspell the "tokenizer" then Elasticsearch will
just use the standard analyzer, completely against intentions).
This commit removes lenient URL parameter parsing. The strategy is
simple: when a request is handled and a parameter is touched, we mark it
as such. Before the request is actually executed, we check to ensure
that all parameters have been consumed. If there are remaining
parameters yet to be consumed, we fail the request with a list of the
unconsumed parameters. An exception has to be made for parameters that
format the response (as opposed to controlling the request); for this
case, handlers are able to provide a list of parameters that should be
excluded from tripping the unconsumed parameters check because those
parameters will be used in formatting the response.
Additionally, some inconsistencies between the parameters in the code
and in the docs are corrected.

On Windows the JDK uses `CreateFileW` which has a stupidly high
limit for the number of `Handle`s it can make - `16 * 1024 * 1024`.
So this isn't really a problem on Windows at all.
Closes#20732
today it's not possible to use date-math efficiently with the `_rollover`
API. This change adds support for date-math in the target index as well as
support for preserving the math logic when an existing index that was created with
a date math expression all subsequent indices are created with the same expression.
this change adds a hard limit to `index.number_of_shard` that prevents
indices from being created that have more than 1024 shards. This is still
a huge limit and can only be changed via settings a system property.
Surprise! You can use sliced scroll to easily parallelize reindex
and friend. They support it because they use the same infrastructure
as a regular search to parse the search request. While we would like
to make an "automatic" option for parallelizing reindex, this manual
option works right now and is pretty convenient!
This commit fixes the documentation for configuring the Java I/O temp
dir which incorrectly suggested using the -D flag as a parameter on the
command line; these flags have been removed and should now be specified
as arguments to the JVM using either the ES_JAVA_OPTS environment
variable or using the jvm.options configuration file.

Adds a cat api endpoint: /_cat/templates and its more specific version, /_cat/templates/{name}.
It looks something like:
$ curl "localhost:9200/_cat/templates?v"
name template order version
sushi_california_roll *avocado* 1 1
pizza_hawaiian *pineapples* 1
pizza_pepperoni *pepperoni* 1
The specified version (only allows * globs) looks like:
$ curl "localhost:9200/_cat/templates/pizza*"
name template order version
pizza_hawaiian *pineapples* 1
pizza_pepperoni *pepperoni* 1
Partially specified columns:
$ curl "localhost:9200/_cat/templates/pizza*?v=true&h=name,template"
name template
pizza_hawaiian *pineapples*
pizza_pepperoni *pepperoni*
The help text:
$ curl "localhost:9200/_cat/templates/pizza*?help"
name | n | template name
template | t | template pattern string
order | o | template application order number
version | v | version

With the unified release process across the elastic stack, download
links for all products are changing. This change updates docs referring
to the old download and packages urls.
Note that this change also updates the plugin installation command as
the url for downloads is being changed to be consistent with that for
packages (both plural).
The serial collector is not suitable for running with a server
application like Elasticsearch and can decimate performance and lead to
cluster instability. This commit adds a bootstrap check to prevent usage
of the serial collector when Elasticsearch is running in production
mode.

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!

We can now run templates using `explain` and/or `profile` parameters.
Which is interesting when you have defined a complicated profile but want to debug it in an easier way than running the full query again.
You can use `explain` parameter when running a template:
```js
GET /_search/template
{
"file": "my_template",
"params": {
"status": [ "pending", "published" ]
},
"explain": true
}
```
You can use `profile` parameter when running a template:
```js
GET /_search/template
{
"file": "my_template",
"params": {
"status": [ "pending", "published" ]
},
"profile": true
}
```
Funny node names have been removed in #19456 and replaced by UUID. This commit removes these obsolete node names and replace them by real UUIDs in the documentation.

During a networking partition, cluster states updates (like mapping changes or shard assignments)
are committed if a majority of the masters node received the update correctly. This means that the current master has access to enough nodes in the cluster to continue to operate correctly. When the network partition heals, the isolated nodes catch up with the current state and get the changes they couldn't receive before. However, if a second partition happens while the cluster
is still recovering from the previous one *and* the old master is put in the minority side, it may be that a new master is elected which did not yet catch up. If that happens, cluster state updates can be lost.
This commit fixed 95% of this rare problem by adding the current cluster state version to `PingResponse` and use them when deciding which master to join (and thus casting the node's vote).
Note: this doesn't fully mitigate the problem as a cluster state update which is issued concurrently with a network partition can be lost if the partition prevents the commit message (part of the two phased commit of cluster state updates) from reaching any single node in the majority side *and* the partition does allow for the master to acknowledge the change. We are working on a more comprehensive fix but that requires considerate work and is targeted at 6.0.
