Henning Andersen bf444b9f02 Store Pending Deletions Fix (#40345)
FilterDirectory.getPendingDeletions does not delegate, fixed
temporarily by overriding in StoreDirectory.

This in turn caused duplicate file name use after a trimUnsafeCommits
had been done, since a new IndexWriter would not consider the pending
deletes in IndexFileDeleter. This should only happen on windows (AFAIK).

Reenabled doing index updates for all tests using
IndexShardTests.indexOnReplicaWithGaps (which could fail due to above
when using mocked WindowsFS).

Added getPendingDeletions delegation to all elasticsearch
FilterDirectory subclasses that were not trivial test-only overrides to
minimize the risk of hitting this issue in another case.

Removes typed calls from YAML REST tests (#37611)
This PR attempts to remove all typed calls from our YAML REST tests. The PR adds include_type_name: false to create index requests that use a mapping and also to put mapping requests. It also removes _type from index requests where they haven't already been removed. The PR ignores tests named *_with_types.yml since this are specifically testing typed API behaviour.

The change also includes changing the test harness to add the type _doc to index, update, get and bulk requests that do not specify the document type when the test is running against a mixed 7.x/6.x cluster.

Make hits.total an object in the search response (#35849)
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

Add a new "contains" feature (#34738)
The contains syntax was added in #30874 but the skips were not properly
put in place.
The java runner has the feature so the tests will run as part of the
build, but language clients will be able to support it at their own
pace.

Upgrade to Lucene-7.5.0-snapshot-608f0277b0 (#32390)
The main highlight is the removal of the reclaim_deletes_weight in the TieredMergePolicy.
The es setting index.merge.policy.reclaim_deletes_weight is deprecated in this commit and the value is ignored. The new merge policy setting setDeletesPctAllowed should be added in a follow up.

Introduce index store plugins (#32375)
Today we allow plugins to add index store implementations yet we are not
doing this in our new way of managing plugins as pull versus push. That
is, today we still allow plugins to push index store providers via an on
index module call where they can turn around and add an index
store. Aside from being inconsistent with how we manage plugins today
where we would look to pull such implementations from plugins at node
creation time, it also means that we do not know at a top-level (for
example, in the indices service) which index stores are available. This
commit addresses this by adding a dedicated plugin type for index store
plugins, removing the index module hook for adding index stores, and by
aggregating these into the top-level of the indices service.

Add support for switching distribution for all integration tests (#30874)
* remove left-over comment

* make sure of the property for plugins

* skip installing modules if these exist in the distribution

* Log the distrbution being ran

* Don't allow running with integ-tests-zip passed externally

* top level x-pack/qa can't run with oss distro

* Add support for matching objects in lists

Makes it possible to have a key that points to a list and assert that a
certain object is present in the list. All keys have to be present and
values have to match. The objects in the source list may have additional
fields.

example:
```
  match:  { 'nodes.$master.plugins': { name: ingest-attachment }  }
```

* Update plugin and module tests to work with other distributions

Some of the tests expected that the integration tests will always be ran
with  the `integ-test-zip` distribution so that there will be no other
plugins loaded.

With this change, we check for the presence of the plugin without
assuming exclusivity.

* Allow modules to run on other distros as well

To match the behavior of tets.distributions

* Add and use a new `contains` assertion

Replaces the  previus changes that caused `match` to do a partial match.

* Implement PR review comments

Ryan Ernst 212f24aa27 Tests: Clean up rest test file handling (#21392)
This change simplifies how the rest test runner finds test files and
removes all leniency.  Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.

Simon Willnauer ecb01c15b9 Fold InternalSearchHits and friends into their interfaces (#23042)
We have a bunch of interfaces that have only a single implementation
for 6 years now. These interfaces are pretty useless from a SW development
perspective and only add unnecessary abstractions. They also require
lots of casting in many places where we expect that there is only one
concrete implementation. This change removes the interfaces, makes
all of the classes final and removes the duplicate `foo` `getFoo` accessors
in favor of `getFoo` from these classes.

Nik Everett f5f2149ff2 Remove much ceremony from parsing client yaml test suites (#22311)
* Remove a checked exception, replacing it with `ParsingException`.
* Remove all Parser classes for the yaml sections, replacing them with static methods.

I did not rewrite the parsers using `ObjectParser` because I don't think it is worth it right now.

Ryan Ernst 7a2c984bcc Test: Remove multi process support from rest test runner (#21391)
At one point in the past when moving out the rest tests from core to
their own subproject, we had multiple test classes which evenly split up
the tests to run. However, we simplified this and went back to a single
test runner to have better reproduceability in tests. This change
removes the remnants of that multiplexing support.

Nik Everett 9270e8b22b Rename client yaml test infrastructure
This makes it obvious that these tests are for running the client yaml
suites. Now that there are other ways of running tests using the REST
client against a running cluster we can't go on calling the shared
client yaml tests "REST tests". They are rest tests, but they aren't
**the** rest tests.

Nik Everett a95d4f4ee7 Add Location header and improve REST testing
This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

https://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the
appropriate location.

Closes #19079

This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.

Ali Beyad 19d0dbcd17 Removes waiting for yellow cluster health upon index (#19460)
creation in the REST tests, as we no longer need it due
to index creation now waiting for active shard copies
before returning (by default, it waits for the primary of
each shard, which is the same as ensuring yellow health).

Ryan Ernst a4503c2aed Plugins: Remove name() and description() from api
In 2.0 we added plugin descriptors which require defining a name and
description for the plugin. However, we still have name() and
description() which must be overriden from the Plugin class. This still
exists for classpath plugins. But classpath plugins are mainly for
tests, and even then, referring to classpath plugins with their class is
a better idea. This change removes name() and description(), replacing
the name for classpath plugins with the full class name.

Simon Willnauer 502a775a7c Add primitive to shrink an index into a single shard (#18270)
This adds a low level primitive operations to shrink an existing
index into a new index with a single shard. This primitive expects
all shards of the source index to allocated on a single node. Once the target index is initializing on the shrink node it takes a snapshot of the source index shards and copies all files into the target indices data folder. An [optimization](https://issues.apache.org/jira/browse/LUCENE-7300) coming in Lucene 6.1 will also allow for optional constant time copy if hard-links are supported by the filesystem. All mappings are merged into the new indexes metadata once the snapshots have been taken on the merge node.

To shrink an existing index all shards must be moved to a single node (one instance of each shard) and the index must be read-only:

```BASH
$ curl -XPUT 'http://localhost:9200/logs/_settings' -d '{
    "settings" : {
        "index.routing.allocation.require._name" : "shrink_node_name",
        "index.blocks.write" : true 
    }
}
```
once all shards are started on the shrink node. the new index can be created via:

```BASH
$ curl -XPUT 'http://localhost:9200/logs/_shrink/logs_single_shard' -d '{
    "settings" : {
        "index.codec" : "best_compression",
        "index.number_of_replicas" : 1
    }
}'
```

This API will perform all needed check before the new index is created and selects the shrink node based on the allocation of the source index. This call returns immediately, to monitor shrink progress the recovery API should be used since all copy operations are reflected in the recovery API with byte copy progress etc.

The shrink operation does not modify the source index, if a shrink operation should
be canceled or if the shrink failed, the target index can simply be deleted and
all resources are released.

Also removes ensureCanWrite since this already passes the
TRUNCATE_EXISTING flag when opening.

Adds a REST test that fails without this fix due to the classloader
isolation.

Additionally, move SmbDirectoryWrapper into an elasticsearch package instead of a lucene one, so this would be found at compile time instead of runtime.

Ryan Ernst ef4f0a8699 Test: Make rest test framework accept http directly for the test cluster
The rest test framework, because it used to be tightly integrated with
ESIntegTestCase, currently expects the addresses for the test cluster to
be passed using the transport protocol port. However, it only uses this
to then find the http address.

This change makes ESRestTestCase extend from ESTestCase instead of
ESIntegTestCase, and changes the sysprop used to tests.rest.cluster,
which now takes the http address.

Ryan Ernst 3b78267c71 Plugins: Remove site plugins
Site plugins used to be used for things like kibana and marvel, but
there is no longer a need since kibana (and marvel as a kibana plugin)
uses node.js. This change removes site plugins, as well as the flag for
jvm plugins. Now all plugins are jvm plugins.

Simon Willnauer 66d5d0c4f2 Replace IndexSettings annotation with a full-fledged class
The @IndexSettings annoationat has been used to differentiate between node-level
and index level settings. It was also decoupled from realtime-updates such that
the settings object that a class got injected when it was created was static and
not subject to change when an update was applied. This change removes the annoation
and replaces it with a full-fledged class that adds type-safety and encapsulates additional
functionality as well as checks on the settings.

Nik Everett 2cc97a0d3e Remove and ban @Test
There are three ways `@Test` was used. Way one:

```java
@Test
public void flubTheBlort() {
```

This way was always replaced with:

```java
public void testFlubTheBlort() {
```

Or, maybe with a better method name if I was feeling generous.

Way two:

```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
    methodThatThrows();
}
```

This way of using `@Test` is actually pretty OK, but to get the tools to ban
`@Test` entirely it can't be used. Instead:

```java
public void testFoo() {
    try {
        methodThatThrows();
        fail("Expected IllegalArgumentException");
    } catch (IllegalArgumentException e ) {
        assertThat(e.getMessage(), containsString("something"));
    }
}
```

This is longer but tests more than the old ways and is much more precise.
Compare:

```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
    some();
    copy();
    and();
    pasted();
    methodThatThrows();
    code();  // <---- This was left here by mistake and is never called
}
```

to:

```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
    some();
    copy();
    and();
    pasted();
    try {
        methodThatThrows();
        fail("Expected IllegalArgumentException");
    } catch (IllegalArgumentException e ) {
        assertThat(e.getMessage(), containsString("something"));
    }
}
```

The final use of test is:

```java
@Test(timeout=1000)
public void testFoo() {
    methodThatWasSlow();
}
```

This is the most insidious use of `@Test` because its tempting but tragically
flawed. Its flaws are:
1. Hard and fast timeouts can look like they are asserting that something is
faster and even do an ok job of it when you compare the timings on the same
machine but as soon as you take them to another machine they start to be
invalid. On a slow VM both the new and old methods fail. On a super-fast
machine the slower and faster ways succeed.
2. Tests often contain slow `assert` calls so the performance of tests isn't
sure to predict the performance of non-test code.
3. These timeouts are rude to debuggers because the test just drops out from
under it after the timeout.

Confusingly, timeouts are useful in tests because it'd be rude for a broken
test to cause CI to abort the whole build after it hits a global timeout. But
those timeouts should be very very long "backstop" timeouts and aren't useful
assertions about speed.

For all its flaws `@Test(timeout=1000)` doesn't have a good replacement __in__
__tests__. Nightly benchmarks like http://benchmarks.elasticsearch.org/ are
useful here because they run on the same machine but they aren't quick to check
and it takes lots of time to figure out the regressions. Sometimes its useful
to compare dueling implementations but that requires keeping both
implementations around. All and all we don't have a satisfactory answer to the
question "what do you replace `@Test(timeout=1000)`" with. So we handle each
occurrence on a case by case basis.

For files with `@Test` this also:
1. Removes excess blank lines. They don't help anything.
2. Removes underscores from method names. Those would fail any code style
checks we ever care to run and don't add to readability. Since I did this manually
I didn't do it consistently.
3. Make sure all test method names start with `test`. Some used to end in `Test` or start
with `verify` or `check` and they were picked up using the annotation. Without the
annotation they always need to start with `test`.
4. Organizes imports using the rules we generate for Eclipse. For the most part
this just removes `*` imports which is a win all on its own. It was "required"
to quickly remove `@Test`.
5. Removes unneeded casts. This is just a setting I have enabled in Eclipse and
forgot to turn off before I did this work. It probably isn't hurting anything.
6. Removes trailing whitespace. Again, another Eclipse setting I forgot to turn
off that doesn't hurt anything. Hopefully.
7. Swaps some tests override superclass tests to make them empty with
`assumeTrue` so that the reasoning for the skips is logged in the test run and
it doesn't "look like" that thing is being tested when it isn't.
8. Adds an oxford comma to an error message.

The total test count doesn't change. I know. I counted.
```bash
git checkout master && mvn clean && mvn install | tee with_test
git no_test_annotation master && mvn clean && mvn install | tee not_test
grep 'Tests summary' with_test > with_test_summary
grep 'Tests summary' not_test > not_test_summary
diff with_test_summary not_test_summary
```

These differ somewhat because some tests are skipped based on the random seed.
The total shouldn't differ. But it does!
```
1c1
< [INFO] Tests summary: 564 suites (1 ignored), 3171 tests, 31 ignored (31 assumptions)
---
> [INFO] Tests summary: 564 suites (1 ignored), 3167 tests, 17 ignored (17 assumptions)
```

These are the core unit tests. So we dig further:
```bash
cat with_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > with_test_suites
cat not_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > not_test_suites
diff <(sort with_test_suites) <(sort not_test_suites)
```

The four tests with lower test numbers are all extend `AbstractQueryTestCase`
and all have a method that looks like this:

```java
@Override
public void testToQuery() throws IOException {
    assumeTrue("test runs only when at least a type is registered", getCurrentTypes().length > 0);
    super.testToQuery();
}
```

It looks like this method was being double counted on master and isn't anymore.

David Pilato f230eabc15 [cloud-azure] Split azure plugin in 3 plugins
Until now we had a cloud-azure plugin which is providing 3 distinct features:

* discovery on Azure
* snapshot/restore on Aure
* SMB store

This commit splits the plugin by feature so people can use either one or the other or both features.

Doc is updated accordingly.
