The assertBusy method currently has both a Runnable and Callable
version. This has caused confusion with type inference and lambdas
sometimes, in particular with java 9. This change removes the callable
version as nothing was actually using it.
The retry test has failed a couple of times in CI because it wasn't able
to cause any retries. Putting it in a bash `while` loop shows that it
eventually does fail that way. The seed "4F6477A9C999CA20" seems especially
good at failing to get retries. It doesn't fail all the time, but more
than most.
This adds a retry to each test case, retrying a maximum of 10 times or
until it causes the retries. I've seen it fail to get retries 7 times
in a row but not go beyond that. Retrying doesn't seem to really hurt
the test runtime all that much. Most of the time is in the startup
cost.

Rather than having one win against the other, reject duplicated apis. Also enforce the convention that see the api name have the same name as the name of the rest spec file that defines it.
Named queries have a performance bug when they are used with expensive queries
that need to perform a lot of work up-front like fuzzy or range queries
(including with points). The reason is that they currently re-create the weight
and scorer for every hit. Instead we should create weights exactly once and
use a single Scorer for all documents that are on the same segment.
Before the query extraction would have been aborted and the percolator query would be marked as unknown.
This resulted in a situation that these queries always need to be evaluated by the memory index at search time.
By adding support for this query many more percolator query candidate hits can skip the expensive memory index verification step. For example the `match` query parser returns a MatchNoDocsQuery if the query terms are removed by text analysis (lets query text only contained stop words).
Remove the arbitrary limit on epoch_millis and epoch_seconds of 13 and 10
characters, respectively. Instead allow any character combination that can
be converted to a Java Long.
Update the docs to reflect this change.
This commit is a slight refactoring of the use of environment variables
in replacing property placeholders. In commit
115f983827 the constructor for
Settings.Builder was made package visible to provide a hook for tests to
mock obtaining environment variables. But we do not need to go that far
and can instead provide a small hook for this for tests without opening
up the constructor. Thus, in this commit we refactor
Settings.Builder#replacePropertyPlaceholders to a package-visible method
that accepts a function providing environment variables by names. The
public-visible method just delegates to this method passing in
System::getenv and tests can use the package-visible method to mock the
behavior they need without relying on external environment variables.
This change makes ES compile with java9 again, build 118.
* There are a handful of changes due to failure to determine types during compile.
* The attachment plugins which use tika needed to have tika upgraded in order to pickup fixes there for java 9.
* azure discovery and s3 repository indirectly depend on jaxb, which is no longer in the default modules. They now add a jaxb dependency externally, and make JarHell allow for this package.
This commit modifies the settings test for environment variables
placeholders so that it is reproducible. The underlying issue is that
the set of environment variables from system to system can vary, and
this means that's we can never be sure that a failing test will be
reproducible. This commit simplifies this test to not rely on external
forces that could influence reproducibility.

This removes the ScriptMode class entirely, which was an enum with two
options (ON and OFF) which essentially boiled down to true and false.
Now the boolean values are used instead.
We write to Netty channels in an async fashion, but notify listeners via
a transport service adapter before we are certain that the channel write
succeeded. In particular, the tracer logs are implemented via a
transport service adapter and this means that we can write tracer logs
before a write was successful and in some cases the write might fail
leading to misleading logs. This commit attaches the transport service
adapters to channel writes as a listener so that the notification occurs
only after a successful write.

The default jvm.options file ships with the -server flag to force the
server VM on systems where the server VM is not the default. However,
the method of starting the JVM via the Windows service does not support
the command-line flags for selecting the VM because it starts from a
DLL that is specific to the server or client VM. Thus, we need to
filter these options from the jvm.options configuration file when
installing the Windows service.

Today if a shard fails during initialization phase due to misconfiguration, broken disks,
missing analyzers, not installed plugins etc. elasticsaerch keeps on trying to initialize
or rather allocate that shard. Yet, in the worst case scenario this ends in an endless
allocation loop. To prevent this loop and all it's sideeffects like spamming log files over
and over again this commit adds an allocation decider that stops allocating a shard that
failed more than N times in a row to allocate. The number or retries can be configured via
`index.allocation.max_retry` and it's default is set to `5`. Once the setting is updated
shards with less failures than the number set per index will be allowed to allocate again.
Internally we maintain a counter on the UnassignedInfo that is reset to `0` once the shards
has been started.
