Generally we don't advocate for using `stored_fields`, and we're interested in
eventually removing the need for this parameter. So it's best to avoid using
stored fields in our docs examples when it's not actually necessary.
Individual changes:
* Avoid using 'stored_fields' in our docs.
* When defining script fields in top-hits, de-emphasize stored fields.
* Scripting: Deprecate general cache settings
* Add script.disable_max_compilations_rate setting
* Move construction to ScriptCache
* Use ScriptService to do updates of CacheHolder
* Remove fallbacks
* Add SCRIPT_DISABLE_MAX_COMPILATIONS_RATE_SETTING to ClusterSettings
* Node scope
* Use back compat
* 8.0 for bwc
* script.max_compilations_rate=2048/1m -> script.disable_max_compilations_rate=true in docker compose
* do not guard in esnode
* Doc update
* isSnapshotBuild() -> systemProperty 'es.script.disable_max_compilations_rate', 'true'
* Do not use snapshot in gradle to set max_compilations_rate
* Expose cacheHolder as package private
* monospace 75/5m in cbreaker docs, single space in using
* More detail in general compilation rate error
* Test: don't modify defaultConfig on upgrade
Add the character position of a scripting error to error responses.
The contents of the `position` field are experimental and subject to
change. Currently, `offset` refers to the character location where the
error was encountered, `start` and `end` define a range of characters
that contain the error.
eg.
```
{
"error": {
"root_cause": [
{
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"y = x;",
" ^---- HERE"
],
"script": "def x = new ArrayList(); Map y = x;",
"lang": "painless",
"position": {
"offset": 33,
"start": 29,
"end": 35
}
}
```
Refs: #50993
* Check position only for 7.7+
* 7.7 && decrement before assign
* Use correct experimental tag, update doc test responses, off by one yaml
* Do not duplicate error.caused_by in replacement
* Add position under causedby
The example use of a scoring script was incorrectly using a filter
script query, which has no scoring, and thus no _score variable
avialable. This commit converts the example doc to using the newer
script_score query.
* [DOCS] Add template docs to scripts. Reorder template examples.
* Adds a 'Search template' section to the 'How to use scripts' chapter.
This links to the 'Search template' chapter for detailed info and
examples.
* Reorders and retitles several examples in the 'Search template'
chapter. This is primarily to make examples for storing, deleting, and
using search templates more prominent.
* Change <templatename> to <templateid>
