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.
Relates #26884
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.
Today we represent each value of a list setting with it's own dedicated key
that ends with the index of the value in the list. Aside of the obvious
weirdness this has several issues especially if lists are massive since it
causes massive runtime penalties when validating settings. Like a list of 100k
words will literally cause a create index call to timeout and in-turn massive
slowdown on all subsequent validations runs.
With this change we use a simple string list to represent the list. This change
also forbids to add a settings that ends with a .0 which was internally used to
detect a list setting. Once this has been rolled out for an entire major
version all the internal .0 handling can be removed since all settings will be
converted.
Relates to #26723
Add fuzzy_transpositions parameter to multi_match and query_string queries.
Add fuzzy_transpositions, fuzzy_prefix_length and fuzzy_max_expansions
parameters to simple_query_string query.
The single shard optimization that we have in our search api changes the type of response returned by the query transport action name based on the shard search request. if the request goes to one shard, we will do query and fetch at the same time, hence the response will be different. The proxying layer used in cross cluster search was not aware of this distinction, which causes serialization issues every time a cross cluster search request goes to a single shard and goes through a gateway node which has to forward the shard request to a data node. The coordinating node would then expect a QueryFetchSearchResult while the gateway would return a QuerySearchResult.
Closes#26833
While working on #26751, I found that we are passing the container name on every single method although we don't need it as it is stored within the blobstore object already.
This commit simplifies a bit that part of the code.
It also removes `repositoryName` from AzureBlobStore which was not used anymore.
Also we move some properties in AzureBlobContainer to `private` members.
This is a follow up to #26764. That commit set SO_LINGER to 0 in order
to fix a scenario where we were running out of resources during CI. We
are primarily interested in setting this to 0 when stopping the
tranport. Allowing TIMED_WAIT is standard for other failure scenarios
during normal operation.
Unfortunately this commit set SO_LINGER to 0 every time we close
NodeChannels. NodeChannels can be closed in case of an exception or
other failures (such as parsing a response). We want to only disable
linger when actually shutting down.
In 5.x pure wildcard queries `*` in `query_string` are rewritten to `exists` query for efficiency.
Though this introduced a change in the document that match such queries because
`exists` query also return documents with an empty value for the field.
This change clarifies this behavior for 5.x and beyond.
Closes#26801
* review
Since `#getAsMap` exposes internal representation we are trying to remove it
step by step. This commit is cleaning up some xcontent writing as well as
usage in tests
Update provides:
* Adds support for Gradle 4.0 (without deprecation warning)
* Full Java 9 support through ASM 6.0
Version 2.4 was buggy (it broke Gradle dependencies on SourceSets), but this version fixes it.
This change adds cgroup memory usage/limit to the OS stats section of
the node stats on Linux. This information is useful because in Docker
containers the standard node stats report the host memory limit, not
taking account of extra restrictions that may have been applied to the
container.
The original idea was to store these values as Long, truncating any values
outside the range of long. However, this meant that in the relatively common
case of no limit being applied, users would not see the same value in the OS
stats as they see by querying Linux directly. So instead the values are stored
as String. This change places a burden on consumers of the strings to
convert the strings to numbers and decide what to do about extremely large
values, but there will be very few consumers and they would need to have a
policy for dealing with "no limit" in any case.
