This commit removes and forbids the use of lowercase ells ('l') in long
literals because they are often hard to distinguish from the digit
representing one ('1').

We are leaking all kinds of resources if something during Node#close() barfs.
This commit cuts over to a list of closeables to release resources that
also closed remaining services if one or more services fail to close.
Closes#13685
In junit5, a neat assertion method is added which makes testing expected
failures a little more straightforward. The block of code that is
expected to throw is passed in with a lambda expression, and the caught
exception returned for inspection.
This change adds an implementation of expectThrows to ESTestCase. When
junit5 is eventually releassed and we switch to it, we can remove.
Now MasterNodeOperations, ReplicationAllShards, ReplicationSingleShard, BroadcastReplication and BroadcastByNode actions keep track of their parent tasks.
Note for many of the settings we had a netty specific override to a generic transport setting. I have removed those as they are not needed imo (ex. "transport.connections_per_node.recovery" was overriden by "transport.netty.connections_per_node.recovery", which I removed). The netty prefix was kept for settings that are tied to the netty universe - ex. "transport.netty.max_cumulation_buffer_capacity"
Closes#16200
In the early days Elasticsearch used to use the index name as the index identity. Around 1.0.0 we introduced a unique index uuid which is stored in the index setting. Since then we used that uuid in a few places but it is by far not the main identifier when working with indices, partially because it's not always readily available in all places.
This PR start to make a move in the direction of using uuids instead of name by making sure that the uuid is available on the Index class (currently just a wrapper around the name) and as such also available via ShardRouting and ShardId.
Note that this is by no means an attempt to do the right thing with the uuid in all places. In almost all places it falls back to the name based comparison that was done before. It is meant as a first step towards slowly improving the situation.
Closes#16217
This commit limits the `index.translog.sync_interval` to a value not less than `100ms` and
removes the support for fsync on every operation which used to be enabled if `index.translog.sync_interval` was set to `0s`
Now this pr also only schedules an async fsync if the durability is set to `async`. By default not async task is scheduled.
Closes#16152
This commit method renames the ScriptEngineService interface methods
types, extensions, and sandboxed to getTypes, getExtensions, and
isSandboxed, respectively.
This commit converts the script mode settings to the new settings
infrastructure. This is a major refactoring of the handling of script
mode settings. This refactoring is necessary because these settings are
determined at runtime based on the registered script engines and the
registered script contexts.
The search_after parameter provides a way to efficiently paginate from one page to the next. This parameter accepts an array of sort values, those values are then used by the searcher to sort the top hits from the first document that is greater to the sort values.
This parameter must be used in conjunction with the sort parameter, it must contain exactly the same number of values than the number of fields to sort on.
NOTE: A field with one unique value per document should be used as the last element of the sort specification. Otherwise the sort order for documents that have the same sort values would be undefined. The recommended way is to use the field `_uuid` which is certain to contain one unique value for each document.
Fixes#8192
When a Version is passed to `Settings#put(String, Version)` it's id is used as
an integer which should also be used to deserialize it on the consumer end.
Today AssertinLocalTransport expects Version#toString() to be used which can lead
to subtile bugs in tests.
This commit migrates all the settings under network service to the new settings infra.
It also adds some chaining utils to make fall back settings slightly less verbose.
Breaking (but I think acceptable) - network.tcp.no_delay and network.tcp.keep_alive used to accept the value `default` which make us not set them at all on netty. Our default was true so we weren't using this feature. I removed it and now we only accept a true boolean.
* `test.cluster.node.seed` was only used in one place where it wasn't adding value and was now replaced with a constant
* `tests.portsfile` is now an official setting and has been renamed to `node.portsfile`
this commit also convert `search.default_keep_alive` and `search.keep_alive_interval` to the new settings infrastrucutre
