This starts breaking up the `UpdateHelper.prepare` method so that each piece can
be individually unit tested. No actual functionality has changed.
Note however, that I did add a TODO about `ctx.op` leniency, which I'd love to
remove as a separate PR if desired.
Previously you could set the system property tests.es.path.data and
start the run task with a custom data directory. A change in core to
detect duplicate settings broke this. That change should stay, but we
can work around this easily by only setting path.data to the data
directory if tests.es.path.data is not set.

TransportService and RemoteClusterService are closely coupled already today
and to simplify remote cluster integration down the road it can be a direct
dependency of TransportService. This change moves RemoteClusterService into
TransportService with the goal to make it a hidden implementation detail
of TransportService in followup changes.
This adds `-XX:-OmitStackTraceInFastThrow` to the JVM arguments
which *should* prevent the JVM from omitting stack traces on
common exception sites. Even though these sites are common, we'd
still like the exceptions to debug them.
This also adds the flag when running tests and adapts some tests
that had workarounds for the absense of the flag.

This commit removes a few duplicates from the list of checkstyle

We are back to having a 140-column limit. While at some point we will
apply auto-formatting tools to the code base, that is a down-the-road
thing and adjusting the suppressions now shaves minutes off the build

Separates cluster state publishing from applying cluster states:
- ClusterService is split into two classes MasterService and ClusterApplierService. MasterService has the responsibility to calculate cluster state updates for actions that want to change the cluster state (create index, update shard routing table, etc.). ClusterApplierService has the responsibility to apply cluster states that have been successfully published and invokes the cluster state appliers and listeners.
- ClusterApplierService keeps track of the last applied state, but MasterService is stateless and uses the last cluster state that is provided by the discovery module to calculate the next prospective state. The ClusterService class is still kept around, which now just delegates actions to ClusterApplierService and MasterService.
- The discovery implementation is now responsible for managing the last cluster state that is used by the consensus layer and the master service. It also exposes the initial cluster state which is used by the ClusterApplierService. The discovery implementation is also responsible for adding the right cluster-level blocks to the initial state.
- NoneDiscovery has been renamed to TribeDiscovery as it is exclusively used by TribeService. It adds the tribe blocks to the initial state.
- ZenDiscovery is synchronized on state changes to the last cluster state that is used by the consensus layer and the master service, and does not submit cluster state update tasks anymore to make changes to the disco state (except when becoming master).
Control flow for cluster state updates is now as follows:
- State updates are sent to MasterService
- MasterService gets the latest committed cluster state from the discovery implementation and calculates the next cluster state to publish
- MasterService submits the new prospective cluster state to the discovery implementation for publishing
- Discovery implementation publishes cluster states to all nodes and, once the state is committed, asks the ClusterApplierService to apply the newly committed state.
- ClusterApplierService applies state to local node.

Start moving built in analysis components into the new analysis-common
module. The goal of this project is:
1. Remove core's dependency on lucene-analyzers-common.jar which should
shrink the dependencies for transport client and high level rest client.
2. Prove that analysis plugins can do all the "built in" things by moving all
"built in" behavior to a plugin.
3. Force tests not to depend on any oddball analyzer behavior. If tests
need anything more than the standard analyzer they can use the mock
analyzer provided by Lucene's test infrastructure.
This commit adds a call to jstack to see where each node is stuck when
starting up, if a timeout occurs. This also decreases the timeout back
to 30 seconds.
We want to upgrade to Lucene 7 ahead of time in order to be able to check whether it causes any trouble to Elasticsearch before Lucene 7.0 gets released. From a user perspective, the main benefit of this upgrade is the enhanced support for sparse fields, whose resource consumption is now function of the number of docs that have a value rather than the total number of docs in the index.
Some notes about the change:
- it includes the deprecation of the `disable_coord` parameter of the `bool` and `common_terms` queries: Lucene has removed support for coord factors
- it includes the deprecation of the `index.similarity.base` expert setting, since it was only useful to configure coords and query norms, which have both been removed
- two tests have been marked with `@AwaitsFix` because of #23966, which we intend to address after the merge

The method Boolean#getBoolean is dangerous. It is too easy to mistakenly
invoke this method thinking that it is parsing a string as a
boolean. However, what it actually does is get a system property with
the specified string, and then attempts to use usual crappy boolean
parsing in the JDK to parse that system property as boolean with
complete leniency (it parses every input value into either true or
false); that is, this method amounts to invoking
Boolean#parseBoolean(String) on the result of
System#getProperty(String). Boo. This commit bans usage of this method.

Now that we are on gradle 3.3, we can take advantage of a fix that was
made in 2.14 which properly handles disabling transitive dependencies in
pom generation. As it was currently, we actually ended up generated two
exclusions sections in the generated pom. This is yet another example of
why we need validation on the pom files with our generation here, but I
leave that for another day because I still don't know a good way to do
it.
This moves `updateReplicaRequest` to `createPrimaryResponse` and separates the
translog updating to be a separate function so that the function purpose is more
easily understood (and testable).
It also separates the logic for `MappingUpdatePerformer` into two functions,
`updateMappingsIfNeeded` and `verifyMappings` so they don't do too much in a
single function. This allows finer-grained error testing for when a mapping
fails to parse or be applied.
Finally, it separates parsing and version validation for
`executeIndexRequestOnReplica` into a separate
method (`prepareIndexOperationOnReplica`) and adds a test for it.

This commit adds a build listener to the integ test runner which will
print out an excerpt of the logs from the integ test cluster if the test
run fails. There are future improvements that can be made (for example,
to dump excerpts from dependent clusters like in tribe node tests), but
this is a start, and would help with simple rest tests failures that we
currently don't know what actually happened on the node.
This will allow us to get rid of deprecation warnings that appear when
using 3.3, and also get rid of extra logic for 2.13 required because of
the progress logger.
Search took time uses an absolute clock to measure elapsed time, and

took time, but still provides an absolute clock for the components of

In Gradle 3.4, the buildSrc plugin seems to be packaged into a jar before it is accessed by the rest of the build and the signatures file for the third-party audit task cannot be accessed as

While trying to improve the failure output in #23547, the stderr was
also captured from jrunscript. This was under the assumption that stderr
is only written to in case of an error. However, with java 9, when
JAVA_TOOL_OPTIONS are set, they are output to stderr. And our CI sets
JAVA_TOOL_OPTIONS for some reason. This commit fixes the jrunscript call
to use a separate buffer for stderr.
A previous change to the multi-search request execution to avoid stack
overflows regressed on limiting the number of concurrent search requests
from a batched multi-search request. In particular, the replacement of
the tail-recursive call with a loop could asynchronously fire off all of
the remaining search requests in the batch while max concurrent search
requests are already executing. This commit attempts to address this
issue by taking a more careful approach to the initial problem of
recurisve calls. The cause of the initial problem was due to possibility
of individual requests completing on the same thread as invoked the
search action execution. This can happen, for example, in cases when an
individual request does not resolve to any shards. To address this
problem, when an individual request completes we check if it completed
on the same thread as fired off the request. In this case, we loop and
otherwise safely recurse. Sadly, there was a unit test to check that the
maximum number of concurrent search requests was not exceeded, but that
test was broken while modifying the test to reproduce a case that led to
the possibility of stack overflow. As such, we randomize whether or not
search actions execute on the same thread as the thread that invoked the
action.

This commit upgrades to the newest version of randomized runner. There
is a new additional check that allows ensuring the working directory

example, if you previously told the runner to not wipe the directory, in
order to investigate a failure, the wipe option will delete this data
upon re-running the test.

This commit changes the build hash to be the string "Unknown" when for
some reason this build hash is not available. This aligns the value with
the value we use when the hash is not available from the jar
manifest. This situation can occur when running tests from a worktree
which is not currently handled correctly by JGit, the upstream
dependency that is used to acquire the hash. This causes problems when
running tests locally because the warning header pattern expects a hash
or the string "Unknown". While the warning header pattern be changed to
allow "N/A" as well, it seemed more sensible to align the value here
with the value when the hash is not available from the jar manifest.
Relates #23421
This change adds a new test task, platformTest, which runs `gradle test
integTest` within a vagrant host. This will allow us to still test on
all the supported platforms, but be able to standardize on the tools
provided in the host system, for example, with a modern version of git
that can allow #22946.
In order to have sufficient memory and cpu to run the tests, the
vagrantfile has been updated to use 8GB and 4 cpus by default. This can
be customized with the `VAGRANT_MEMORY` and `VAGRANT_CPUS` environment
variables. Also, to save time to show this can work, it currently uses
the same Vagrantfile the packaging tests do. There are a lot of cleanups
we can do to how the gradle-vagrant tasks work, including generating
Vagrantfile altogether, but I think this is fine for now as the same
machines that would run platformTest run packagingTest, and they are
relatively beefy machines, so the higher memory and cpu for them, with
either task, should not be an issue.
This commit fixes the reproduce line output when the vagrant packagingTest
fails. Before only the `gradle packagingTest` would be output, but the
seed and list of versions was swallowed by groovy with an ancillary
failure (due to the `+` being on the wrong line for a string
continuation). With the new reproduce line, it is now output next to
the task right after failure, contains the actual task (specific to the
box that fails), and contains the seed. It also no longer contains the
upgrade versions list, as the seed is used to determine which of those
to use, and the same file would be read when testing a failure on a
particular git commit. Finally, this also ties bats test setup directly
to packagingTest, instead of to the vagrant up command.
When a rest integ test has multiple nodes, each node is supposed to not
start configuring itself until the first node has been started, so that
the unicast host information can be written. However, this was never
explicitly setup to occur, and we were just very lucky with the current
gradle version and stability of the code always produced a task graph
that had node0 starting first. With the recent refactorings to integ
tests, the order has changed. This commit fixes the ordering by adding
an explicit dependency between the first node and the other nodes.
This commit moves the LICENSE.txt and NOTICE.txt files for each plugin
to be alongside the other plugin files, inside the elasticsearch subdir.
This ensures those files are installed alongside the plugin.
Gradle's finalizedBy on tasks only ensures one task runs after another,
but not immediately after. This is problematic for our integration tests
since it allows multiple project's integ test clusters to be
simultaneously. While this has not been a problem thus far (gradle 2.13
happened to keep the finalizedBy tasks close enough that no clusters
were running in parallel), with gradle 3.3 the task graph generation has
changed, and numerous clusters may be running simultaneously, causing
memory pressure, and thus generally slower tests, or even failure if the
system has a limited amount of memory (eg in a vagrant host).
This commit reworks how integ tests are configured. It adds an
`integTestCluster` extension to gradle which is equivalent to the current
`integTest.cluster` and moves the rest test runner task to
`integTestRunner`. The `integTest` task is then just a dummy task,
which depends on the cluster runner task, as well as the cluster stop
task. This means running `integTest` in one project will both run the
rest tests, and shut down the cluster, before running `integTest` in
another project.
In #23253 we added an the ability to incrementally reduce search results.
This change exposes the parameter to control the batch since and therefore

This commit enforces the requirement of Content-Type for the REST layer and removes the deprecated methods in transport

explicitly have been added to forbidden apis to prevent more of these from entering our code base.

Now that debian is disabled, we are seeing similar failures with fedora
not able to install java. This commit temporarily disables fedora until
it is once again stable.
This changes the way that replica failures are handled such that not all
failures will cause the replica shard to be failed or marked as stale.
In some cases such as refresh operations, or global checkpoint syncs, it is
"okay" for the operation to fail without the shard being failed (because no data
is out of sync). In these cases, instead of failing the shard we should simply
fail the operation, and, in the event it is a user-facing operation, return a
5xx response code including the shard-specific failures.
This was accomplished by having two forms of the `Replicas` proxy, one that is
for non-write operations that does not fail the shard, and one that is for write
operations that will fail the shard when an operation fails.

Currently, stored scripts use a namespace of (lang, id) to be put, get, deleted, and executed. This is not necessary since the lang is stored with the stored script. A user should only have to specify an id to use a stored script. This change makes that possible while keeping backwards compatibility with the previous namespace of (lang, id). Anywhere the previous namespace is used will log deprecation warnings.
The new behavior is the following:
When a user specifies a stored script, that script will be stored under both the new namespace and old namespace.
Take for example script 'A' with lang 'L0' and data 'D0'. If we add script 'A' to the empty set, the scripts map will be ["A" -- D0, "A#L0" -- D0]. If a script 'A' with lang 'L1' and data 'D1' is then added, the scripts map will be ["A" -- D1, "A#L1" -- D1, "A#L0" -- D0].
When a user deletes a stored script, that script will be deleted from both the new namespace (if it exists) and the old namespace.
Take for example a scripts map with {"A" -- D1, "A#L1" -- D1, "A#L0" -- D0}. If a script is removed specified by an id 'A' and lang null then the scripts map will be {"A#L0" -- D0}. To remove the final script, the deprecated namespace must be used, so an id 'A' and lang 'L0' would need to be specified.
When a user gets/executes a stored script, if the new namespace is used then the script will be retrieved/executed using only 'id', and if the old namespace is used then the script will be retrieved/executed using 'id' and 'lang'
This commit introduces sequence-number-based recovery. When a replica
has fallen out of sync, rather than performing a file-based recovery we
first attempt to replay operations since the last local checkpoint on
the replica. To do this, at the start of recovery the replica tells the
primary what its local checkpoint is. The primary will then wait for all
operations between that local checkpoint and the current maximum
sequence number to complete; this is to ensure that there are no gaps in
the operations that will be replayed from the primary to the
replica. This is a best-effort attempt as we currently have no
guarantees on the primary that these operations will be available; if we
are not able to replay all operations in the desired range, we just
fallback to file-based recovery. Later work will strengthen the
guarantees.

This commit adds a MessyRestTestPlugin to the gradle build. It extends
StandaloneRestTestPlugin. The main piece of functionality that it adds
is to copy plugin-metadata from dependencies into the

ensure that permissions for dependencies are applied when running the
tests.
A current limitation is that the permissions are applied differently
than in the distribution sources. When permissions are granted to all
depedencies for a module or plugin, the permissions are granted to all
dependencies on the classpath for tests besides a few hardcoded
exclusions:
- es core
- es test framework
- lucene test framework
- randomized runner
- junit library

If we conditionally do random things, e.g. initialize a node only after the first test, we have to make sure that we unconditionally create a new seed calling random.nextLong(), then initialize the node under a private randomness context. This makes sure that any random usage through Randomness.get() will retrieve the proper random instance through RandomizedContext.current().getRandom(). When running under private randomness, the context will return the Random instance that was created with the provided seed (forked from the main random instance) rather than the main Random that's exposed to tests as well. Otherwise tests become non repeatable because that initialization part happens only before the first executed test.
Moved field values `toXContent` logic to `GetField` (from `GetResult`), which outputs its own fields, and can also parse them now. Also added `fromXContent` to `GetResult` and `GetResponse`.
The start object and end object for `GetResponse` output have been moved to `GetResult#toXContent`, from the corresponding rest action. This makes it possible to have `toXContent` and `fromXContent` completely symmetric, as parsing requires looping till an end object is found which is weird when the corresponding `toXContent` doesn't print that out.
This also introduces the foundation for testing retrieval of _source and stored field values.
Sequence BWC logic consists of two elements:
1) Wire level BWC using stream versions.
2) A changed to the global checkpoint maintenance semantics.
For the sequence number infra to work with a mixed version clusters, we have to consider situation where the primary is on an old node and replicas are on new ones (i.e., the replicas will receive operations without seq#) and also the reverse (i.e., the primary sends operations to a replica but the replica can't process the seq# and respond with local checkpoint). An new primary with an old replica is a rare because we do not allow a replica to recover from a new primary. However, it can occur if the old primary failed and a new replica was promoted or during primary relocation where the source primary is treated as a replica until the master starts the target.
1) Old Primary & New Replica - this case is easy as is taken care of by the wire level BWC. All incoming requests will have their seq# set to `UNASSIGNED_SEQ_NO`, which doesn't confuse the local checkpoint logic (keeping it at `NO_OPS_PERFORMED`)
2) New Primary & Old replica - this one is trickier as the global checkpoint service currently takes all in sync replicas into consideration for the global checkpoint calculation. In order to deal with old replicas, we change the semantics to say all *new node* in sync replicas. That means the replicas on old nodes don't count for the global checkpointing. In this state the seq# infra is not fully operational (you can't search on it, because copies may miss it) but it is maintained on shards that can support it. The old replicas will have to go through a file based recovery at some point and will get the seq# information at that point. There is still an edge case where a new primary fails and an old replica takes over. I'lll discuss this one with @ywelsch as I prefer to avoid it completely.
This PR also re-enables the BWC tests which were disabled. As such it had to fix any BWC issue that had crept in. Most notably an issue with the removal of the `timestamp` field in #21670.
The commit also includes a fix for the default value of the seq number field in replicated write requests (it was 0 but should be -2), that surface some other minor bugs which are fixed as well.
Last - I added some debugging tools like more sane node names and forcing replication request to implement a `toString`
If you write a yaml test with a `warnings` section in a `do` block
that doesn't also have a corresponding `skip` section for `warnings`
then client test runners that don't support `warnings` will fail.
This causes the elasticsearch build to fail so we catch these errors
earlier.

Changes the build to recognize `NORELEASE` as well as `NOCOMMIT` to
mean the same thing as `norelease` and `nocommit` respectively. This
is useful because people have been using them that way but haven't
realized that only the lowercase versions worked.
This also explicitly forbids silly things like `NoReLeAsE` and
`noCOMMIT`, failing the build and telling you to spell them properly.
