Our convention is to use lower case when naming things "Tcp". For
example, `TcpTransport`. This commit renames the outlier
(TcpTransportTests) to use lower case.
When a node which contains the primary shard is unavailable, the primary
stats (and the total stats) of an `IndexStats` will be empty for a short
moment (while the primary shard is being relocated). However, we assume
that these stats are always non-empty when handling `_cat/indices` in
RestIndicesAction. This commit checks the content of these stats before
accessing.
Closes#26942
While opening a connection to a node, a channel can subsequently
close. If this happens, a future callback whose purpose is to close all
other channels and disconnect from the node will fire. However, this
future will not be ready to close all the channels because the
connection will not be exposed to the future callback yet. Since this
callback is run once, we will never try to disconnect from this node
again and we will be left with a closed channel. This commit adds a
check that all channels are open before exposing the channel and throws
a general connection exception. In this case, the usual connection retry
logic will take over.

We had a TODO about adding tests around cached boxing. In #24077
I tracked down the uncached boxing tests and saw the TODO. Cached
boxing testing is a fairly small extension to that work.
This commit fixes an issue with the handling of paths containing
parentheses on Windows. When such a path is used as a component of
Elasticsearch home, then a later echo statement that is guarded by an if
will fail because the parentheses in the path will be confused with the
parentheses defining the if block. This commit fixes the issue by
protecting this echo statement by wrapping the possibly offending path
in quotes.

With this commit we simplify our network layer by only allowing to define a
fixed receive predictor size instead of a minimum and maximum value. This also
means that the following (previously undocumented) settings are removed:
* http.netty.receive_predictor_min
* http.netty.receive_predictor_max
Using an adaptive sizing policy in the receive predictor is a very low-level
optimization. The implications on allocation behavior are extremely hard to grasp
(see our previous work in #23185) and adaptive sizing does not provide a lot of
benefits (see benchmarks in #26165 for more details).
Previously collisions in headers between old and new contexts could be silently ignored, allowing the original context's headers to "win". This commit fixes the headers to require they are disjoint.
the only nodes preference was used as a replacement of `_primary` which was removed. Sadly, it's not the same as we also check that it makes sense - i.e., that the given node has a shard copy. Since the test uses indices with >1 shards, the primaries may be spread to multiple nodes. Using one (like it currently does) will fail for some primaries. Using all will probably end up hitting all nodes.
This commit removed the `_only_nodes` usage in favor a simple search

Cache final result instead of result of advanceExact.
Fix SortedNumericDoubleValues does not test MEDIAN mode
Replace deprecated random string generation method
The rolling-upgrade test was only writing the "minimum_master_nodes" setting to the configuration file of the old nodes, but not the upgraded ones.
Also changes the value of "minimum_master_nodes" from "number_of_nodes" to "(number_of_nodes / 2) + 1".
Today we return a `String[]` that requires copying values for every
access. Yet, we already store the setting as a list so we can also directly
return the unmodifiable list directly. This makes list / array access in settings
a much cheaper operation especially if lists are large.
The shard preference _primary, _replica and its variants were useful
for the asynchronous replication. However, with the current impl, they
are no longer useful and should be removed.
Closes#26335
Right now if you run `gradle regen` on Windows you'll get `CRLF` line
endings on all the ANTLR generated files because we run
```
ant.fixcrlf(srcdir: outputPath) {
patternset(includes: 'Painless*.java')
}
```
The docs for fixcrlf say that the default line endings that it
corrects to is based on the OS:
https://ant.apache.org/manual/Tasks/fixcrlf.html
This change locks it to `LF`.
This test has been failing in th Ruby runner, since it assumed the `headers` feature,
but was not annotated accordingly.
This patch adds the `skip` clause with the `headers` feature.
Closes#26896
Support for search_after and geo distance sorting is broken when the optimized LatLonDocValuesField.distanceSort is used.
This commit fixes the parsing of the search_after value for this case.
* Add additional low-level logging handler
We have the trace handler which is useful for recording sent messages
but there are times where it would be useful to have more low-level
logging about the events occurring on a channel. This commit adds a
logging handler that can be enabled by setting a certain log level
(org.elasticsearch.transport.netty4.ESLoggingHandler) to trace that
provides trace logging on low-level channel events and includes some
information about the request/response read/write events on the channel
as well.
* Remove imports
* License header
* Remove redundant
* Add test
* More assertions
We should unwrap the cause looking for any suppressed errors or root
causes that are errors when checking if we should maybe die. This commit
causes that to be the case.

This commit changes the log level on a write and flush failure to warn
as this is not necessarily an Elasticsearch problem but more likely
indicative of an infrastructure problem.
