Pius 40f3b5ab76 Update snapshots.asciidoc
>However, the version of the new cluster should be the same or newer than the cluster that was

Afaik, you can't restore a snapshot to a newer cluster that is not consecutively newer (i.e. can't restore 1.x snapshot to a 5.x cluster).  This is to clarify the statement above moving forward.

Lee Hinman 2be52eff09 Circuit break the number of inline scripts compiled per minute
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,

        "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.

Lee Hinman 124a9fabe3 Circuit break on aggregation bucket numbers with request breaker
This adds new circuit breaking with the "request" breaker, which adds
circuit breaks based on the number of buckets created during
aggregations. It consists of incrementing during AggregatorBase creation

This also bumps the REQUEST breaker to 60% of the JVM heap now.

The output when circuit breaking an aggregation looks like:

```json

  "shard" : 0,
  "index" : "i",
  "node" : "a5AvjUn_TKeTNYl0FyBW2g",

Colin Goodheart-Smithe b717ad8eb6 Enable option to use request cache for size > 0
Previously if the size of the search request was greater than zero we would not cache the request in the request cache.

This change retains the default behaviour of not caching requests with size > 0 but also allows the `request_cache=true` query parameter
to enable the cache for requests with size > 0

And deprecate it for 5.0.

Nik Everett b665d8a187 Painless: Add flag support to regexes
Painless: Add support for //m
Painless: Add support for //s
Painless: Add support for //i

Painless: Add support for //U
Painless: Add support for //l
  This means "literal" and is exposed for completeness sake with
  the java api.
Painless: Add support for //c
  c enables Java's CANON_EQ (canonical equivalence) flag which makes
  unicode characters that are canonically equal match. Java's javadoc
  gives "a\u030A" being equal to "\u00E5". That is that the "a" code
  point followed by the "combining ring above" code point is equal to
  the "a with combining ring above" code point.

Nik Everett 8d3ef742db Painless: =~ and ==~ operators
Adds support for the find operator (=~) and the match operator (==~)
to painless's regexes. Also whitelists most of the Matcher class and
documents regex support in painless.

The find operator (=~) returns a boolean that is the result of building
a matcher on the lhs with the Pattern on the RHS and calling `find` on
it. Use it like this:

```
if (ctx._source.last =~ /b/)
```

The match operator (==~) returns boolean like find but instead of calling
`find` on the Matcher it calls `matches`.

```
if (ctx._source.last ==~ /[^aeiou].*[aeiou]/)
```

Finally, if you want the actual matcher you do:

```
Matcher m = /[aeiou]/.matcher(ctx._source.last)
```

Jason Tedor da74323141 Register thread pool settings
This commit refactors the handling of thread pool settings so that the
individual settings can be registered rather than registering the top
level group. With this refactoring, individual plugins must now register
their own settings for custom thread pools that they need, but a
dedicated API is provided for this in the thread pool module. This
commit also renames the prefix on the thread pool settings from
"threadpool" to "thread_pool". This enables a hard break on the settings
so that:
 - some of the settings can be given more sensible names (e.g., the max
   number of threads in a scaling thread pool is now named "max" instead
   of "size")
 - change the soft limit on the number of threads in the bulk and
   indexing thread pools to a hard limit
 - the settings names for custom plugins for thread pools can be
   prefixed (e.g., "xpack.watcher.thread_pool.size")
 - remove dynamic thread pool settings

Lee Hinman a4060f7436 Remove vestiges of script engine sandboxing
This removes all the mentions of the sandbox from the script engine
services and permissions model. This means that the following settings
are no longer supported:

```yaml
script.inline: sandbox
script.stored: sandbox
```

Instead, only a `true` or `false` value can be specified.

Since this would otherwise break the default-allow parameter for
languages like expressions, painless, and mustache, all script engines
have been updated to have individual settings, for instance:

```yaml
script.engine.groovy.inline: true
```

Would enable all inline scripts for groovy. (they can still be
overridden on a per-operation basis).

Expressions, Painless, and Mustache all default to `true` for inline,
file, and stored scripts to preserve the old scripting behavior.

This gives better coverage and consistency with the scripting APIs, by
whitelisting the primary search scripting API classes and using them instead
of only Map and List methods.

For example, accessing fields can now be done with `.value` instead of `.0`
because `getValue()` is whitelisted. For now, access to a document's fields in
this way (loads) are fast-pathed in the code, to avoid dynamic overhead.

Access to geo fields and geo distance functions is now supported.

Nik Everett 4b1c116461 Generate and run tests from the docs
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.

Jason Tedor 5608fa7ac1 Actually bound the generic thread pool
This commit actually bounds the size of the generic thread pool. The
generic thread pool was of type cached, a thread pool with an unbounded
number of workers and an unbounded work queue. With this commit, the
generic thread pool is now of type scaling. As such, the cached thread
pool type has been removed. By default, the generic thread pool is
constructed with a core pool size of four, a max pool size of 128 and
idle workers can be reaped after a keep-alive time of thirty seconds
expires. The work queue for this thread pool remains unbounded.

Daniel Mitterdorfer 52b2016447 Limit request size on transport level
With this commit we limit the size of all in-flight requests on
transport level. The size is guarded by a circuit breaker and is
based on the content size of each request.

By default we use 100% of available heap meaning that the parent
circuit breaker will limit the maximum available size. This value
can be changed by adjusting the setting

network.breaker.inflight_requests.limit

Boaz Leskes 6dd164d0bd Include pings from client nodes in master election
We currently have a `discovery.zen.master_election.filter_client` setting that control whether their ping responses are ignored for master election (which is the current default). With the push to treat client nodes as normal nodes (and promote the transport/rest clients for client work), this should be changed. This commit remove this setting and it's companion `discovery.zen.master_election.filter_data` setting (currently defaulting to  false) in favor of singe `discovery.zen.master_election.ignore_non_master_pings` setting with more intuitive name (defaulting to false).

Jason Tedor 8a05c2a2be Bootstrap does not set system properties
Today, certain bootstrap properties are set and read via system
properties. This action-at-distance way of managing these properties is
rather confusing, and completely unnecessary. But another problem exists
with setting these as system properties. Namely, these system properties
are interpreted as Elasticsearch settings, not all of which are
registered. This leads to Elasticsearch failing to startup if any of
these special properties are set. Instead, these properties should be
kept as local as possible, and passed around as method parameters where
needed. This eliminates the action-at-distance way of handling these
properties, and eliminates the need to register these non-setting
properties. This commit does exactly that.

Additionally, today we use the "-D" command line flag to set the
properties, but this is confusing because "-D" is a special flag to the
JVM for setting system properties. This creates confusion because some
"-D" properties should be passed via arguments to the JVM (so via
ES_JAVA_OPTS), and some should be passed as arguments to
Elasticsearch. This commit changes the "-D" flag for Elasticsearch
settings to "-E".

David Pilato 26863a4d75 Fix: Change docs on "node client" to not use an in-memory node
Currently we suggesting users create a Node (using NodeBuilder in 2.x) to have a client that is capable of keeping up-to-date information. This is generally a bad idea as it means elasticsearch has no control over eg max heap size or gc settings, and is also problematic for users because they must deal with dependency collisions (and in 2.x+ dependencies of elasticsearch itself).

A better alternative, and what we should document, is to run a local elasticsearch server using bin/elasticsearch, and then use the transport client to connect to that local node. This local connection is virtually free, and allows the client code to be completely isolated from the elasticsearch process. Plugins are then also easy to deal with: just install them in elasticsearch as usual.

Simon Willnauer f5e4cd4616 Remove recovery threadpools and throttle outgoing recoveries on the master
Today we throttle recoveries only for incoming recoveries. Nodes that have a lot
of primaries can get overloaded due to too many recoveries. To still keep that at bay
we limit the number of threads that are sending files to the target to overcome this problem.

The right solution here is to also throttle the outgoing recoveries that are today unbounded on
the master and don't start the recovery until we have enough resources on both source and target nodes.

The concurrency aspects of the recovery source also added a lot of complexity and additional threadpools
that are hard to configure. This commit removes the concurrent streamns notion completely and sends files
in the thread that drives the recovery simplifying the recovery code considerably.
Outgoing recoveries are not throttled on the master via a allocation decider.

Robert Muir 7595c4a3c8 Improve network docs
This makes some minor improvements (does not fix all problems!)

It reorders unicast disco in elasticsearch.yml to be right after the network host,
for better locality.

It removes the warning (unreleased) about publish addresses, lets try to really discourage setting
that unless you need to (behind a proxy server). Most people should be fine with `network.host`

Finally it reorganizes the network docs page a bit:

We add a table of 4 "basic" settings at the very beginning:

* network.host
* discovery.zen.ping.unicast.hosts
* http.port
* transport.tcp.port

The first two being the most important, which addresses to bind and talk to, and the other two
being the port numbers.

The rest of the stuff I tried to simplify and reorder under "advanced" headers.

This is just a quick stab, I still think we need more effort into this thing, but we gotta start somewhere.

Which gives back the private IP address, for example `10.240.0.2`.

http://metadata.google.internal/computeMetadata/v1/instance/network-interfaces/0/externalIp

Gives back the public Ip address, for example `130.211.108.21`.

As we have for `ec2`, we can support new network host settings:

* `_gce:privateIp:X_`: The private IP address of the machine for a given network interface.
* `_gce:hostname_`: The hostname of the machine.
* `_gce_`: Same as `_gce:privateIp:0_` (recommended).

    Handle node mode across entire test cluster

    We used static methods reading sys properties to define the node mode
    per cluster. this had lots of problems when tests couldn't cope with
    mixed or only local mode. Now we are passing it down to the cluster from the test
    which allows to @SuppressNetworkMode / @SupressLocalMode on the test to force
    consistent node configurations.

Robert Muir 68307aa9f3 Fix network binding for ipv4/ipv6
When elasticsearch is configured by interface (or default: loopback interfaces),
bind to all addresses on the interface rather than an arbitrary one.

If the publish address is not specified, default it from the bound addresses
based on the following sort ordering:

* ipv4/ipv6 (java.net.preferIPv4Stack, defaults to true)
* ordinary addresses
* site-local addresses
* link local addresses
* loopback addresses

One one address is published, and multicast is still always over ipv4: these
need to be future improvements.

Today this is "unofficial" as conf/scripts, but some people
want to share scripts across different nodes and so on. Because
they cannot configure it, they are forced to use dirty hacks
like symbolic links, which isnt going to work: we aren't going
to recursively scan conf/ and add permissions to all link targets
underneath it, thats crazy.

I really hate adding yet another configuration knob here, but
users resorting to using symlinks are going to be frustrated,
and do things in a more insecure way.

This is basically just a port of the existing functionality, which
is also the reason why this is not a refactoring of the plugin manager,
which will come in a separate commit.

Boaz Leskes 1e35bf3171 Discovery: wait on incoming joins before electing local node as master
During master election each node pings in order to discover other nodes and validate the liveness of existing nodes. Based on this information the node either discovers an existing master or, if enough nodes are found (based on `discovery.zen.minimum_master_nodes>>) a new master will be elected.

Currently, the node that is elected as master will currently update it the cluster state to indicate the result of the election. Other nodes will submit a join request to the newly elected master node. Instead of immediately processing the election result, the elected master
node should wait for the incoming joins from other nodes, thus validating the elections result is properly applied. As soon as enough nodes have sent their joins request (based on the `minimum_master_nodes` settings) the cluster state is modified.

Note that if `minimum_master_nodes` is not set, this change has no effect.

David Pilato d57de59158 Simplify Plugin Manager for official plugins
Plugin Manager can now use another simplified form when a user wants to install an official plugin hosted at elasticsearch download service.

The form we use is:

```sh
bin/plugin install pluginname
```

As plugins share now the same version as elasticsearch, we can automatically guess what is the exact current version of the plugin manager script.

Also, download service will now use `/org.elasticsearch.plugins/pluginName/pluginName-version.zip` URL path to download a plugin.

If the older form is provided (`user/plugin/version` or `user/plugin`), we will still use:

 * elasticsearch download service at `/user/plugin/plugin-version.zip`
 * maven central with groupIp=user, artifactId=plugin and version=version
 * github with user=user, repoName=plugin and tag=version
 * github with user=user, repoName=plugin and branch=master if no version is set

Note that community plugin providers can use other download services by using `--url` option.

If you try to use the new form with a non core elasticsearch plugin, the plugin manager will reject
it and will give you all known core plugins.

```
Usage:
    -u, --url     [plugin location]   : Set exact URL to download the plugin from
    -i, --install [plugin name]       : Downloads and installs listed plugins [*]
    -t, --timeout [duration]          : Timeout setting: 30s, 1m, 1h... (infinite by default)
    -r, --remove  [plugin name]       : Removes listed plugins
    -l, --list                        : List installed plugins
    -v, --verbose                     : Prints verbose messages
    -s, --silent                      : Run in silent mode
    -h, --help                        : Prints this help message

 [*] Plugin name could be:
     elasticsearch-plugin-name    for Elasticsearch 2.0 Core plugin (download from download.elastic.co)
     elasticsearch/plugin/version for elasticsearch commercial plugins (download from download.elastic.co)

Adrien Grand 38f5cc236a Rename caches.
In order to be more consistent with what they do, the query cache has been
renamed to request cache and the filter cache has been renamed to query
cache.

A known issue is that package/logger names do no longer match settings names,
please speak up if you think this is an issue.

Here are the settings for which I kept backward compatibility. Note that they
are a bit different from what was discussed on #11569 but putting `cache` before
the name of what is cached has the benefit of making these settings consistent
with the fielddata cache whose size is configured by
`indices.fielddata.cache.size`:
 * index.cache.query.enable -> index.requests.cache.enable
 * indices.cache.query.size -> indices.requests.cache.size
 * indices.cache.filter.size -> indices.queries.cache.size

jaymode 6b086dc7db change CORS allow origin default to allow no origins
Today, we disable CORS by default, but if a user simply enables CORS their instance of
elasticsearch will allow cross origin requests from anywhere, as the default value for allowed
origins is `*`.

This changes the default to be `null` so that no origins are allowed and the user must explicitly
specify the origins they wish to allow requests from. The documentation also mentions that there
is a security risk in using `*` as the value.

Information about in-progress snapshot and restore processes is not really metadata and should be represented as a part of the cluster state similar to discovery nodes, routing table, and cluster blocks. Since in-progress snapshot and restore information is no longer part of metadata, this refactoring also enables us to handle cluster blocks in more consistent manner and allow creation of snapshots of a read-only cluster.

Adrien Grand ac7ce2b899 Rivers removal.
While we had initially planned to keep rivers around in 2.0 to ease migration,
keeping support for rivers is challenging as it conflicts with other important
changes that we want to bring to 2.0 like synchronous dynamic mappings updates.
Nothing impossible to fix, but it would increase the complexity of how we
deal with dynamic mappings updates and manage rivers, while handling dynamic
mappings updates correctly is important for resiliency and rivers are on the go.
So removing rivers in 2.0 may well be a better trade-off.

Jack Conradson aa968f6b65 Scripting: Add Field Methods
Added infrastructure to allow basic member methods in the expressions
language to be called.  The methods must have a signature with no arguments.  Also
added the following member methods for date fields (and it should be easy to add more)
* getYear
* getMonth
* getDayOfMonth
* getHourOfDay
* getMinutes
* getSeconds

Allow fields to be accessed without using the member variable [value].
(Note that both ways can be used to access fields for back-compat.)

javanna 7bd7ea8f13 Scripting: allow plugins to define custom operations that they use scripts for
Plugins can now define multiple operations/contexts that they use scripts for. Fine-grained settings can then be used to enable/disable scripts based on each single registered context.

Also added a new generic category called `plugin`, which will be used as a default when the context is not specified. This allows us to restore backwards compatibility for plugins on `ScriptService` by restoring the old methods that don't require the script context and making them internally use the `plugin` context, as they can only be called from plugins.

javanna 83fb0a10e5 Scripting: remove support for script.disable_dynamic setting
Now that fine-grained script settings are supported (#10116) we can remove support for the script.disable_dynamic setting.

Same result as `script.disable_dynamic: false` can be obtained as follows:

```
script.inline: on
script.indexed: on
```
An exception is thrown at startup when the old setting is set, so we make sure we tell users they have to change it rather than ignoring the setting.

javanna d9d1e6a67a Scripting: add support for fine-grained settings
Allow to on/off scripting based on their source (where they get loaded from), the  operation that executes them and their language.

The settings cover the following combinations:

- mode: on, off, sandbox
- source: indexed, dynamic, file
- engine: groovy, expressions, mustache, etc
- operation: update, search, aggs, mapping

The following settings are supported for every engine:

script.engine.groovy.indexed.update:    sandbox/on/off
script.engine.groovy.indexed.search:    sandbox/on/off
script.engine.groovy.indexed.aggs:      sandbox/on/off
script.engine.groovy.indexed.mapping:   sandbox/on/off
script.engine.groovy.dynamic.update:    sandbox/on/off
script.engine.groovy.dynamic.search:    sandbox/on/off
script.engine.groovy.dynamic.aggs:      sandbox/on/off
script.engine.groovy.dynamic.mapping:   sandbox/on/off
script.engine.groovy.file.update:       sandbox/on/off
script.engine.groovy.file.search:       sandbox/on/off
script.engine.groovy.file.aggs:         sandbox/on/off
script.engine.groovy.file.mapping:      sandbox/on/off

For ease of use, the following more generic settings are supported too:

script.indexed: sandbox/on/off
script.dynamic: sandbox/on/off
script.file:    sandbox/on/off

script.update:  sandbox/on/off
script.search:  sandbox/on/off
script.aggs:    sandbox/on/off
script.mapping: sandbox/on/off

These will be used to calculate the more specific settings, using the stricter setting of each combination. Operation based settings have precedence over conflicting source based ones.

Note that the `mustache` engine is affected by generic settings applied to any language, while native scripts aren't as they are static by definition.

Also, the previous `script.disable_dynamic` setting can now be deprecated.

Alexander Reelsen 5eeac2fdf6 Netty: Add HTTP pipelining support
This adds HTTP pipelining support to netty. Previously pipelining was not
supported due to the asynchronous nature of elasticsearch. The first request
that was returned by Elasticsearch, was returned as first response,
regardless of the correct order.

The solution to this problem is to add a handler to the netty pipeline
that maintains an ordered list and thus orders the responses before
returning them to the client. This means, we will always have some state
on the server side and also requires some memory in order to keep the
responses there.

Pipelining is enabled by default, but can be configured by setting the
http.pipelining property to true|false. In addition the maximum size of
the event queue can be configured.

The initial netty handler is copied from this repo
https://github.com/typesafehub/netty-http-pipelining

Boaz Leskes f480969503 [Gateway] set a default of 5m to `recover_after_time` when any to the `expected*Nodes` is set
The `recovery_after_time` tells the gateway to wait before starting recovery from disk. The goal here is to allow for more nodes to join the cluster and thus not start potentially unneeded replications. The `expectedNodes` setting (and friends) tells the gateway when it can start recovering even if the `recover_after_time` has not yet elapsed. However, `expectedNodes` is useless if one doesn't set `recovery_after_time`. This commit changes that by setting a sensible default of 5m for `recover_after_time` *if* a `expectedNodes` setting is present.

Closes #6742
