This processor is useful when all elements of a json array need to be processed in the same way.
This avoids that a processor needs to be defined for each element in an array.
Also it is very likely that it is unknown how many elements are inside an json array.
Modules are an internal implementation detail of our build, and there is
no need to publish them with gradle. This change disables publishing of
all modules.
140 characters is our official line length from CONTRIBUTING.md. It is a
little longer than fits well in github but you can use a userstyle to fix
that. It is perfect for Eclipse and unified diffs but too wide for side by
side diffs. Regardless, its the official limit we've had for years. We just
haven't enforced it automatically and we haven't enforced it using github
because line limits are hard to notice there.
This only hits about 2/3 of the java files - those that didn't have failures
already. If they did have a failure it suppresses them. We should pick files
off that list as time goes on.
For posterity I generated the suppressions by running checkstyle with
ignoreFailures = true, piping the output to a file, and then running it
through this:
perl -ne 'print if s{.*\[ant:checkstyle\] /.+/elasticsearch/}{ <suppress files="} && s{\.java.+}{\.java" checks="LineLength" />}' | uniq
Retrieving distributed DF for TermVectors is beside it's esotheric justification
a very slow process and can cause serious load on the cluster. We also don't have nearly
enough testing for this stuff and given the complexity we should remove it rather than carrying it
around.
During initial cluster forming, when a master is elected, it reaches out to all other masters nodes and ask the last cluster state they persisted. To make sure we select the right state, we must successfully read from a `min_master_nodes` nodes. The gateway currently have specific settings to override this behavior, but I don't think they are ever used. We can drop them and reach out to the discovery layer, the single source of truth for the min master nodes settings.
Closes#16446
This change documents the Terminal abstraction that cli tools use, as
well as simplifies the api to be a minimal set of methods to interact
with a terminal.
Uses a refactored version of Netty's CORS implementation to provide more
robust cross-origin resource request functionality. The CORS specific
Elasticsearch parameters remain the same, just the underlying
implementation has changed.
It has also been refactored in a way that allows dropping in Netty's
CORS handler as a replacement once Elasticsearch is upgraded to Netty 4.
This change rewrites the entire settings filtering mechanism to be immutable.
All filters must be registered up-front in the SettingsModule. Filters that are comma-sparated are
not allowed anymore and check on registration.
This commit also adds settings filtering to the default settings recently added to ensure we don't render
filtered settings.
Early versions of JDK 8 have a compiler bug that prevents assignment to
a definitely unassigned final variable inside the body of a lambda. This
commit adds an early-out to the build process which also gives a useful
error message.
Closes#16418
