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.

Today when sending a REST error to a client, we send the decoded
path. But decoding that path can already be the cause of the error in
which case decoding it again will just throw an exception leading to us
never sending an error back to the client. It would be better to send
the entire raw path to the client and that is what we do in this commit.

When a snapshot initialization fails, the create snapshot method may return before the snapshot metadata in the cluster state is removed. This can cause follow up snapshot-API related calls to fail due to a snapshot still running. This is causing CI failures when we try to delete indices that were participating in failed snapshot to a read-only repository.
Closes#18121
This commit passes the system property tests.logger.level down to the
external nodes launched in integration tests. Specific tests that want
to override the default logging level should push down a setting to
the nodes using cluster configuration instead of pushing down a system
property to the nodes using cluster configuration.

* ESBlobStore tests must move to the test framework if we want to be able to reuse them in the context of plugins.
* To be able to identify more easily what are Integration Tests vs Unit Tests, this commit renames `*AzureTestCase` to `*AzureIntegTestCase`.
* Move some debug level logs to trace level
* Collapse when possible identical catch blocks
* `blobNameFromUri()` does not need anymore to get the container name. We just split the URI after 3 `/` and simply get the remaining part.
* Added a Unit test for that
* As we renamed some existing classes, checkstyle is now complaining about the lines width.
* While we are at it, let's replace all calls to `execute().actionGet()` with `get()`
* Move `readSettingsFromFile()` in a Util class. Note that this class might be useful for other plugins (S3/EC2/Azure-discovery for instance) so may be we should move it to the test framework?
* Replace some part of the code with lambdas
This test fails spuriosly in CI and is not reproducible locally.
With this commit we temporarily increase the log level in a few
packages that are suspected to reveal the cause.
This commit fixes a test bug in the scaling thread pool configuration
test. In particular, the test randomization could select min and max for
a thread pool configuration where both are equal to zero. This is a
violation of the requirements of the ThreadPoolExecutor. With this
commit, we now ensure that the max is bounded below by one.
Before 5.0 for it was required that the percolator queries were cached in jvm heap as Lucene queries for two reasons:
1) Performance. The percolator evaluated all percolator queries all the time. There was no pre-selecting queries that are likely to match like we have today.
2) Updates made to percolator queries were visible in realtime, Today these changes are visible in near realtime. So updating no longer requires the percolator to have the queries in jvm heap.
So having the percolator queries in jvm heap via the percolator cache is now less attractive. Especially when there are many percolator queries then these queries can consume many GBs of jvm heap.
Removing the percolator cache does make the percolate query slower compared to how the execution time in 5.0.0-alpha1 and alpha2, but it is still faster compared to 2.x and before.
Please note: The maps inside the pirvate singleton instance of Defininition are no longer unmodifiable, but nothing from the outside can modify it! All private :-)
Currently the query builders expose the clauses of the span
query as a modifiable list. Instead we should make the that
getter return an unmodifiable list. Also renaming the method
used to add a clause from `clause(spanQuery)` to
`addClause(spanQuery)`.
#18360 introduced an extra lock in order to allow writes while syncing the translog. This caused a potential deadlock with snapshotting code where we first acquire the instance lock, followed by a sync (which acquires the syncLock). However, the sync logic acquires the syncLock first, followed by the instance lock.
I considered solving this by not syncing the translog on snapshot - I think we can get away with just flushing it. That however will create subtleties around snapshoting and whether operations in them are persisted. I opted instead to have slightly uglier code with nest synchronized, where the scope of the change is contained to the TranslogWriter class alone.
Today when parsing settings during bootstrap, we add a system property
for every Elasticsearch setting. Additionally, settings can be set via
system properties. This commit simplifies this situation.
- settings are no longer propogated to system properties
- system properties can not be used to set settings
- the "es." prefix on settings is no longer required (nor permitted)
- test logging has a dedicated system property (tests.logger.level)

* Docs: Improved tokenizer docs
Added descriptions and runnable examples
* Addressed Nik's comments
* Added TESTRESPONSEs for all tokenizer examples
* Added TESTRESPONSEs for all analyzer examples too
* Added docs, examples, and TESTRESPONSES for character filters
* Skipping two tests:
One interprets "$1" as a stack variable - same problem exists with the REST tests
The other because the "took" value is always different
* Fixed tests with "took"
* Fixed failing tests and removed preserve_original from fingerprint analyzer
The preserve_original option to the ASCIIFoldingFilter doesn't
play well with the FingerprintFilter, as it ends up producing
fingerprints like:
"and consistent godel gödel is said sentence this yes"
The goal of the OpenRefine algorithm is to product a small normalized
ASCII fingerprint. There's no need to expose preserve_original.
We often require a random joda DateTimeZone in our tests. Currently
there are a few options for generating such a random DateTimeZone
from the set of available ids. Currently most random picks are not
really reproducable across different jvms because they rely on order
in the ids set implementation. The helper in DateProcessorFactoryTests
thus performs a sort on the set of ids before random picking from
the result, so I moved this to ESTestCase to make it publicly
available and changed all other tests to use that method.
